An intelligent security system based on 5G technology

technical field

The invention relates to the field of security technology, in particular to an intelligent security system based on 5G technology.

Background technique

The security system is the abbreviation of the security system. The security system uses various science and technology such as audio and video, infrared, detection, microwave, control, communication, etc., and adopts various security products and equipment to provide people with a safe living and working environment. system.

Today's communities are basically equipped with security systems. The most common community security system is the access control system. However, the existing access control systems have some problems in the management of people entering and leaving the community:

1. Because in different periods, different communities have different access management requirements for people entering and leaving the community, especially for the access management of some outsiders. To enter the community, outsiders need to open the access control system through security personnel. The security personnel in the community have strict management Outsiders will be registered, but for people who often enter and leave the community but are not residents of the community, such as delivery staff, if they need to register every time they enter and exit, it will greatly increase the workload of security personnel. However, if you do not register and only rely on the identity of the delivery staff, the security personnel will open the access control system for them at will, and there will be potential safety hazards.

2. Some outsiders will enter the community through the access control system when the residents of the community open the access control system, so there are potential safety hazards.

Contents of the invention

The present invention intends to provide an intelligent security system based on 5G technology to adapt to the access management requirements of different communities, to facilitate the management of takeaways entering and leaving the community, and to ensure the safety of residents in the community. The present invention is not only applicable to community scenes and delivery people, but also applicable to company buildings, factory areas and other scenes and couriers.

The present invention provides the following basic solutions: an intelligent security system based on 5G technology, including a 5G communication module, and the intelligent security system communicates with the community access control system through the 5G communication module;

It also includes a collection module, a query module, a judgment module, a passcode generation module and a face recognition module;

The collection module is used to collect the order information of the take-out platform when the order-receiving signal is obtained, and the order information includes user address information, user identity information and takeaway staff identity information;

The query module is used to query the access requirements of the community where the user is located according to the user address information;

The judging module is used to judge whether the community where the user is located allows the delivery person to enter according to the access requirements. If allowed, it is judged whether the community where the user resides needs to pass through the access control system. If necessary, the passcode generation module is triggered to generate a temporary passcode;

The pass code generation module is used to generate a temporary pass code according to the user address information, user identity information and takeaway staff identity information, push it, and send it to the access control system of the corresponding community through the 5G communication module;

The face recognition module is used to collect the facial information of the people entering and leaving the community, and judge whether the people entering and leaving the community are from the community. If they are not from the community, the access control system will be closed and the temporary passcode verification will be activated. The delivery staff will pass the temporary passcode verification. , Open the access control system to enter and exit the community.

Compared with the existing technology, the advantages of this solution are: 1. Collect the current order information in the food delivery platform when the order receiving signal is obtained through the acquisition module, and obtain user address information from it, and then the query module queries the user according to the user address information The entry and exit requirements of the community where the user resides; and then the judging module judges whether the community where the user resides allows takeaways to enter according to the access requirements. If allowed, it judges whether the community where the user resides needs to pass through the access control system. If necessary, the pass code generation module is triggered to generate temporary access For communities that do not allow delivery staff to enter, temporary passcodes are not generated to reduce unnecessary system operation and memory usage, thereby improving system operation speed and more flexibly adapting to different access requirements of the community.

2. A face recognition module is installed at the gate of the community to recognize the faces of people entering and leaving the community. When people who are not in the community are recognized, the access control will be triggered to close, which can prevent outsiders from opening the access control system when the residents of the community open it. In this way, it can be mixed into the community to ensure the safety of life and property of the residents of the community.

3. The pass code generation module generates a temporary pass code based on the user address information, user identity information and delivery staff identity information, pushes it to the delivery staff, and sends it to the access control system of the corresponding community through the 5G communication module; the face recognition module collects the personnel entering and exiting the community Facial information, to determine whether the people entering and exiting the community are people in the community. If not, the access control system will be closed and the temporary pass code verification will be activated. The delivery staff will pass the temporary pass code verification and open the access control system to enter and exit the community, so as to realize food delivery The reasonable management of the entry and exit of the delivery personnel can not only record the entry and exit of the delivery personnel in the community, so as to make inquiries after accidents, but also improve the efficiency of entry and exit, and reduce the burden on security personnel.

Further, the verification of the temporary pass code includes three verification modes: first-level temporary pass code verification, second-level temporary pass code verification and third-level temporary pass code verification;

Level 1 temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2, judging whether the user address information is the address of the community, if the user address information is the address of the community, then open the access control system;

Second level temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2, judging whether the user address information is the address of the community, if the user address information is the address of the community, then judging whether the user is a resident of the community according to the user identity information, if the user is a resident of the community, then opening the access control system;

Three levels of temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2. Determine whether the user address information is the address of the community. If the user address information is the address of the community, judge whether the user is a resident of the community according to the user identity information. If the user is a resident of the community, open the access control system and obtain takeaway Member ID number.

Beneficial effect: the temporary passcode verification includes three verification modes: first-level temporary passcode verification, second-level temporary passcode verification and third-level temporary passcode verification. Different verification modes require different judgments and obtained information. The access control system of the community can choose any verification mode for verification according to its own access requirements. The verification of the first-level temporary passcode only needs to determine whether the user address information is the address of the community. The identification speed is fast and has certain security. The second-level temporary passcode Passcode verification not only needs to determine whether the user’s address information is the address of the community, but also needs to determine whether the user is a resident of the community based on the user’s identity information, which is more secure. The third-level temporary passcode verification not only needs to determine whether the user’s address information is the address of the community. The community address and judging whether the user is a resident of the community also need to obtain the ID number of the delivery person, which has higher security and more comprehensive record information. The choice of three verification modes can better adapt to the access requirements of different communities at different times, and is convenient for the management of the entry and exit of the delivery staff.

Further, the intelligent security system based on 5G technology also includes a position detection module;

The position detection module is used to detect the position information of the delivery person;

The judging module is also used to judge whether the distance between the current location of the delivery person and the user's address is equal to or less than the preset distance according to the location information of the delivery person, and if it is less than, trigger the passcode generation module to push the generated temporary passcode to the takeaway member.

Beneficial effects: the location detection module detects the location information of the delivery person; the judging module judges whether the distance between the delivery person's current location and the user's address is equal to or less than the preset distance according to the location information of the delivery person; Firstly, it is convenient for the delivery staff to find the temporary access code they currently need, and secondly, based on the distance judgment, the temporary access code is pushed, reducing the time for the delivery staff to hold the temporary access code, and improving security.

Further, the intelligent security system based on 5G technology also includes a passcode detection module and a passcode invalidation module;

The communication code detection module is used to detect the unused temporary pass code of the order that the current delivery person is delivering, and the temporary pass code whose user address information is the same community is classified into the same group of temporary pass codes;

The passcode invalidation module is used to detect whether there is an identified temporary passcode in the same group of temporary passcodes, and if so, invalidate other temporary passcodes in the same group of temporary passcodes.

Beneficial effects: the pass code detection module and pass code invalid module are aimed at the situation that the delivery staff delivers multiple users in the same community at the same time. In this case, the delivery staff will get multiple temporary pass codes, but the delivery staff does not need to open the community access control system repeatedly , so invalidate other unnecessary temporary passcodes in time to prevent malicious use of temporary passcodes.

Further, the intelligent security system based on 5G technology also includes a timing module and an early warning module;

The timing module is used to start timing when the delivery person uses the temporary pass code to open the access control, that is, to record the stay time of the delivery person in the community, and stop timing when the delivery person uses the temporary pass code to open the access control again, and the temporary pass is invalid code;

The judging module is also used to judge whether the stay time of the delivery person in the community is greater than the preset stay time, and if it is greater than the preset stay time, an early warning module will be triggered to give an early warning;

The early warning module is used for early warning that the stay time of the delivery staff exceeds the preset stay time.

Beneficial effects: The timing module is used to record the stay time of the delivery person in the community. When the stay time is greater than the preset stay time, the early warning module is used to give an early warning to the security personnel, which is convenient for the security personnel to check the situation and prevent accidents.

Further, the preset stay time is composed of a basic stay time and an automatic cumulative stay time, the basic stay time is the time required for the preset delivery person to enter the community to deliver an order, and the automatic cumulative stay time is based on the current delivery time The user's address information in the order being delivered by the staff is the basic residence time accumulated by the number of other orders in the community.

Beneficial effects: the preset stay time is composed of the basic stay time and the automatic accumulated stay time. When the delivery staff deliver multiple users in the same community at the same time, the preset stay time will be based on the address information of the user in the order currently being delivered by the delivery staff. The number of other orders in the community is automatically increased, so as to reasonably adjust the preset residence time and prevent invalid warnings.

Further, the intelligent security system based on 5G technology also includes a statistical module;

The statistical module is used to count the number of times that the delivery staff enters and exits the community;

The judging module is also used to judge whether the delivery person enters the community for the first time according to the number of times the delivery person enters and exits the community when the delivery person performs temporary passcode verification, and if it is the first time the delivery person enters the community In this community, the access control system is triggered to start the three-level temporary passcode verification.

Beneficial effects: For the first-time delivery staff who enter the community, the three-level temporary passcode verification is activated, so as to obtain comprehensive information of the delivery staff and strengthen the protection of the security of the community.

Specifically, it is connected to the property management platform of each community through the 5G communication module, and the latest access information can be checked on the property management platform through the community name in the user address information. Require.

The judging module is used to judge whether the community where the user is located allows the delivery person to enter according to the access requirements. If allowed, it is judged whether the community where the user resides needs to pass through the access control system. If necessary, the passcode generation module is triggered to generate a temporary passcode.

The pass code generation module is used to generate a temporary pass code according to the user address information, user identity information and delivery person identity information. In this embodiment, a two-dimensional code is used, and the two-dimensional code stores user address information, user identity information and the delivery person identity The information is sent to the corresponding delivery person’s account, pushed to the corresponding delivery person through the delivery platform on the delivery person’s smart device, and sent to the access control system of the corresponding community through the 5G communication module.

The face recognition module is used to collect the facial information of the people entering and leaving the community, and judge whether the people entering and leaving the community are from the community. If they are not from the community, the access control system will be closed and the temporary passcode verification will be activated. The delivery staff will pass the temporary passcode verification. , Open the access control system to enter and exit the community, specifically: through the binocular liveness detection camera installed on the access control system at the entrance and exit of the community, collect the facial information of the people entering and leaving the community, perform face recognition, and connect the binocular liveness detection camera to the access control system to judge the community Whether the person entering or exiting is a member of the community. If not, the access control system will be closed and the temporary passcode verification on the access control system will be activated. The takeaway staff will show the temporary passcode pushed by the takeaway platform on their smart devices for verification. If successful, the access control system will be opened, and the delivery staff can enter and leave the community, and a temporary passcode is unique, and can only be identified twice, and it will fail after the two times, that is, the delivery staff enters the community for identification once, and leaves the community for identification once.

Described temporary pass code verification includes three kinds of verification modes and is respectively: first-level temporary pass code verification, second-level temporary pass code verification and third-level temporary pass code verification, and the community manager can select any verification mode by himself, if not Then the default first-level temporary passcode verification is selected. In this embodiment, the cells all select the first-level temporary passcode verification. The three verification modes are as follows:

Level 1 temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2, judging whether the user address information is the address of the community, if the user address information is the address of the community, then open the access control system;

Second level temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2, judging whether the user address information is the address of the community, if the user address information is the address of the community, then judging whether the user is a resident of the community according to the user identity information, if the user is a resident of the community, then opening the access control system;

Three levels of temporary passcode verification, including:

S1. Identify the passcode, and obtain the user address information, user identity information and delivery person identity information contained in the passcode;

S2. Determine whether the user address information is the address of the community. If the user address information is the address of the community, judge whether the user is a resident of the community according to the user identity information. If the user is a resident of the community, open the access control system and deliver The platform obtains the ID number of the delivery person and records it.

The location detection module is used to detect the location information of the delivery person, specifically locating the location of the delivery person through the delivery person's smart device;

The judging module is also used to determine whether the distance between the current location of the delivery person and the user's address is equal to or less than the preset distance according to the location information of the delivery person. The takeaway platform on the smart device pushes it to the corresponding delivery staff. First, it is convenient for the delivery staff to find the temporary pass code currently needed. Second, it pushes the temporary pass code based on the distance judgment, reducing the time for the delivery staff to hold the temporary pass code. To improve security, in this embodiment, it is assumed that the farthest building in each community is no more than 500 meters from the gate of the community, and the preset distance is 500 meters.

The communication code detection module is used to detect the unused temporary passcode of the order that the current delivery person is delivering on the takeaway platform, and group the temporary passcodes whose user address information is the same community into the same group of temporary passcodes;

The passcode invalidation module is used to detect whether there is an identified temporary passcode in the same group of temporary passcodes, and if it exists, it will be invalid. Once the passcode is recognized once, other temporary passcodes in the same group will be invalid.

The timing module is used to start timing when the delivery person uses the temporary pass code to open the access control, that is, to record the stay time of the delivery person in the community, and stop timing when the delivery person uses the temporary pass code to open the access control again, and the temporary pass is invalid code, that is, the time is recorded when the delivery staff uses the temporary pass code for the first time, and the time is stopped when the delivery staff uses the temporary pass code for the second time.

The judging module is also used to judge whether the stay time of the delivery person in the community is greater than the preset stay time, and if it is greater than the preset stay time, an early warning module is triggered; the preset stay time is automatically accumulated by the basic stay time and Dwelling time, the basic staying time is the time required for the preset delivery person to enter the community to deliver an order, and the automatically accumulated residence time is based on the user address information in the order currently being delivered by the deliveryman for other orders in the community The basic residence time of the accumulated number. The preset stay time will be automatically increased according to the number of other orders in the community based on the user address information in the current order being delivered by the delivery staff, so as to reasonably adjust the preset stay time and prevent invalid warnings. In this embodiment, the basic residence time is 20 minutes.

The early warning module is used to warn the security personnel that there are takeaways whose stay time exceeds the preset stay time. In this embodiment, the early warning module is arranged on the sound and light alarm and the computer. When the judgment module triggers the sound and light alarm to alarm, it will The information contained in the temporary pass code of the time-out deliveryman is sent to the computer.

Specific use: the collection module collects the order information of the food delivery platform when the delivery staff receives the order; the query module queries the corresponding community property management platform according to the user address information in the order information, and obtains the latest access requirements of the community on the management platform ; The judging module judges whether the community where the user is located allows the delivery person to enter according to the access requirements, if allowed, then judges whether the community where the user resides needs to pass through the access control system, if necessary, then triggers the pass code generation module to generate and store user address information, user identity information and the QR code of the identity information of the delivery person, that is, the temporary pass code, and send it to the access control system of the corresponding community through the 5G communication module. For communities where delivery people are not allowed to enter, temporary passcodes are not generated to reduce unnecessary system operation and memory usage, thereby improving system operation speed and more flexibly adapting to different access requirements of the community.

The location detection module locates the location of the delivery person through the delivery person's smart device; the judgment module judges whether the distance between the delivery person's current location and the user's address is less than 500 meters according to the location information of the delivery person, and if it is less than, triggers the passcode generation The module sends the generated temporary passcode to the account of the corresponding delivery person, and pushes it to the corresponding delivery person through the delivery platform on the delivery person's smart terminal.

The binocular liveness detection camera installed on the access control system at the entrance and exit of the community collects the facial information of the people entering and leaving the community for face recognition. People in the community will trigger the closure of the access control system and activate the temporary pass code verification on the access control system, which can prevent outsiders from entering the community through the access control system when the residents of the community open the access control system, thereby ensuring the safety of life and property of the residents of the community .

The takeaway staff presents the temporary passcode pushed by the takeaway platform on their smart devices to verify the first-level temporary passcode. If the verification is successful, the access control system is opened, and the takeaway staff can enter the community. In this way, the reasonable management of the entry and exit of the food delivery personnel can be realized. It can not only record the entry and exit of the delivery personnel in the community, so as to make inquiries after accidents, but also improve the efficiency of entry and exit, and reduce the burden on security personnel.

At the same time, the timing module starts timing when the deliveryman uses the temporary pass code to open the door. Assuming that the number of other orders whose user address information is the community is 1 in the order currently delivered by the deliveryman, the preset stay time is 40 minutes; the judgment module Judging whether the stay time of the delivery person in the community is longer than 40 minutes, if it is longer than 40 minutes, the sound and light alarm will be triggered to alarm, and the information contained in the temporary pass code of the delivery person who has timed out will be sent to the computer, so as to pass through in time The early warning module gives early warning to the security personnel, which is convenient for the security personnel to check the situation and prevent accidents.

In addition, the communication code detection module detects that the number of unused temporary passcodes of the order currently being delivered by the delivery person on the takeaway platform is 2, and will classify the temporary passcodes of the two orders into the same group of temporary passcodes; the invalid passcode module If a temporary passcode is detected and identified once, another temporary passcode of the same group will be invalidated, so as to deal with the situation that the delivery staff delivers multiple users in the same community at the same time. In this case, the delivery staff will get multiple temporary passcodes. However, the delivery staff does not need to open the access control system of the community repeatedly, so the other unnecessary temporary passcodes are invalidated in time to prevent malicious use of temporary passcodes.

Embodiment two

The difference between this embodiment and the foregoing embodiment is that it also includes a statistics module, as shown in FIG. 2 ;

The statistical module is used to count the number of times the delivery staff enters and exits the community, specifically: every time the delivery staff conducts temporary pass code identification twice, it will be added as an entry and exit record, that is, the number of times the delivery staff enters and exits the community;

The judging module is also used to judge whether the delivery person enters the community for the first time according to the number of times the delivery person enters and exits the community when the delivery person performs temporary passcode verification, and if it is the first time that the delivery person enters the community , then the access control system is triggered to start the three-level temporary passcode verification.

For the delivery staff who enter the community for the first time, the three-level temporary passcode verification is activated to obtain comprehensive information of the delivery staff, including the delivery staff's ID number, so as to prevent illegal elements from entering the community disguised as delivery staff and strengthen the control Community security protection.
