The application scenarios of the embodiments of the present invention are explained below:

Fig. 1 is an application scene diagram of the control method of the anti-electric wall device provided by the embodiment of the present invention. The control method of the anti-electric wall device provided by the embodiment of the present invention can be applied to the application scene of indoor leakage protection. Exemplarily, this The execution body of the anti-electric wall device control method provided by the embodiment of the invention may be an electronic device, more specifically, for example, an anti-electric wall device, and the anti-electric wall device may be an independent electronic device, such as a smart socket; Electronic devices in smart home appliances, such as anti-electric wall modules installed in water heaters. In this embodiment, the smart socket is used as the execution subject of the method for controlling the electric wall device provided by the embodiment of the present invention for description. As shown in Figure 1, the power connector of the smart socket is plugged into the indoor power supply, and the indoor power supply is electrically connected to the power supply line; the power adapter of the smart water heater is plugged into the smart socket, and when the smart socket is turned on, the indoor power supply and the power supply are connected. The electrical connection between the smart water heaters so that the smart water heaters are powered. At the same time, smart home appliances such as smart washing machines and smart refrigerators are installed indoors, and the smart washing machines and smart refrigerators are powered by connecting to other indoor power sources.

In the power consumption scenario shown in Figure 1, when a leakage occurs in an indoor smart home appliance, it generally appears as a ground wire electrification. Household appliances on the power lines all have hidden dangers of leakage, which seriously endanger personal safety. In the prior art, for example, smart sockets and other anti-electric wall equipment with anti-leakage function, when an electric leakage signal is detected, the usual solution is to cut off the power supply of some or all of the sockets. At this time, if the leakage device is not directly plugged into the anti-electric wall equipment, even if the power supply of all the sockets is cut off, the leakage phenomenon cannot be eliminated, and the leakage protection of various household appliances in the house cannot be achieved, which will affect the power consumption of users. Safety, therefore, all household appliances must be equipped with anti-electricity wall equipment to eliminate the risk of leakage. However, at the same time, it will increase the cost of generation, use and maintenance of household appliances.

In another related technical solution, for example, smart sockets and other anti-electricity wall equipment with anti-leakage function, when the leakage signal is detected, the leakage signal is uploaded to the cloud server, and the leakage signal is analyzed on the cloud server side , so as to control the power-off of the bound smart home appliances under the same account to realize leakage protection. However, in this technical solution, because the device responsible for power-off control of smart home appliances is a cloud server, and the cloud server needs good network status support to ensure timely response to power leakage accidents of smart home appliances. The problem of untimely response to equipment leakage accidents affects the safety of equipment use.

Therefore, there is an urgent need for a method for controlling electric wall equipment, which can complete leakage protection for multiple home appliances in a house in a local area network without network support.

The technical solution of the present invention and how the technical solution of the present invention solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 2 is a flow chart of a method for controlling an anti-electric wall device provided by an embodiment of the present invention, which is applied to an anti-electric wall device. As shown in Fig. 2, the method for controlling an anti-electric wall device provided by this embodiment includes the following steps:

Step S101 , when an electric leakage signal is detected, a candidate device ID is obtained, where the candidate device ID represents the device ID of an intelligent device under the same local area network as the firewall device.

Exemplarily, the anti-electric wall equipment is, for example, a smart socket, and the anti-electric wall equipment is connected to the indoor power supply, and can detect whether the ground wire is electrified, so as to determine whether electric leakage occurs in the indoor household appliances. Specifically, the leakage signal may be generated according to the ground voltage detected by the firewall device, for example, when the ground voltage is greater than a preset threshold, the leakage information is generated, that is, the leakage signal is detected.

Furthermore, the anti-electric wall equipment has a communication function, and can join and form a local area network. In one possible implementation, the smart device is an electronic device with a network communication function, and the anti-electric wall equipment and other smart devices are joined by other network devices. , such as a local area network formed by routers, anti-electric wall equipment and other intelligent devices are in the same local area network. Among them, the establishment and connection of the local area network can be realized through wireless communication modules such as network cards and bluetooth chips built in the anti-electric wall equipment and other smart devices. repeat.

Wherein, the candidate device identifier is the device identifier of the smart device under the same local area network as the firewall device. Specifically, the device identifier may be the machine serial number, physical address, etc. of the smart device that can be used to distinguish different smart devices. The identification code can obtain candidate device identifications by detecting the device identifications of the registered smart devices in the local area network. Wherein, the method for detecting the device identifier of the device registered in the local area network is a prior art known to those skilled in the art, and will not be repeated here.

Step S102, according to preset security configuration information, determine a target device ID among candidate device IDs, and establish a secure connection with the target home appliance, wherein the target home appliance is a smart device corresponding to the target device ID.

Exemplarily, the security configuration information is the configuration information preset in the firewall device, and the security configuration information is used to indicate the target of leakage detection, more specifically, for smart devices under the same local area network, some of them are household appliances with leakage risk Electrical appliances, such as refrigerators, water heaters, etc., and the other part is terminal equipment that uses low-voltage direct current and has no risk of leakage, such as smart phones and tablet computers. According to the security configuration information, determine the device identification corresponding to the household appliance with the leakage risk, which is the target device identification.

Wherein, in a possible implementation manner, the security configuration information includes identification information, and the identification information is used to indicate the identity of the target device. The security configuration information may be obtained in advance by accessing the cloud server and stored inside the firewall device. The security configuration information may also be user-defined input, and no more examples will be given this time.

Further, after determining the target device ID among the candidate device IDs, a secure connection is established with the target household electrical appliance corresponding to the target device ID through the network communication protocol corresponding to the local area network, so that the firewall device can control the target household electrical appliance. Here, it should be noted that the secure connection established between the anti-electric wall device and the target home appliance means that the target home appliance performs security verification on the anti-electric wall device, and gives the anti-electric wall device such as turning on and off the target home appliance. The process of advanced control permissions of the device. Different from the scheme of turning on and off the home appliances through the cloud service (cloud), because the cloud server has authorized the cloud server through the way of binding the home appliances with the APP when connecting the home appliances, it can guarantee the control process. security. However, the anti-electric wall device control method provided in this embodiment is applied to a local area network. Since the candidate home appliance is discovered after the anti-electric wall device is scanned in the local area network, the connection between the anti-electric wall device and the candidate home appliance cannot be guaranteed. safety. Therefore, based on the security configuration information, you need to perform mutual authorization verification between the anti-wall device and the candidate home appliance, and then give you the high-level control authority of the anti-wall device to control the target home appliance, that is, secure connection.

Furthermore, the reason why the method provided in this embodiment establishes a secure connection with the involved home appliances after detecting the leakage signal is that the solution of the cloud server (cloud) to control the indoor home appliances is different. The overall computing power and data processing power are far lower than those of the cloud server. On this premise, for the sake of the safety of home appliances, usually in the local area network, the target home appliances and anti-electric wall equipment The establishment of a secure connection, that is, the high-level control authority given by the target home appliance to the firewall device, is time-limited. Therefore, the firewall device is required to continuously send requests and data with multiple target home appliances to ensure that the firewall device and Multiple target home appliances are always in a secure connection state, and this solution will cause high loads on the computing resources of the anti-electric wall equipment and problems such as device heating, reduce the stability and service life of the anti-electric wall equipment, and occupy the network resources in the local area network. Network resources affect the overall anti-electricity performance of the anti-electricity wall equipment. However, the solution in this embodiment, after detecting the leakage signal, performs a safe connection, which is equivalent to making a safe connection between the anti-electric wall device and the target home appliance device on demand, and can further reduce the risk of protection by using a single-threaded processing solution connected sequentially. The computing resource requirements of the electric wall equipment can avoid the above-mentioned problems such as the high load of the electric wall equipment and the heating of the equipment, and improve and reduce the stability of the electric wall equipment.

Step S103 , sending control signals to each target household electrical appliance in sequence, so as to sequentially and correspondingly shut down each target household electrical appliance until no electric leakage signal is detected any more.

Further, in the application scenario provided by this embodiment, the number of target household appliances is at least two. After at least two target home appliances are determined, turn off the above-mentioned at least two home appliances one by one. At the same time, as the basic function of the anti-electric wall device, the anti-electric wall device will detect the leakage signal in real time, and continuously turn off each of the above-mentioned target home appliances. , when the leakage signal disappears, it means that the currently closed target home appliance is a leakage device, so as to complete the location of the leakage device, and the remaining target home appliances do not need to continue to be closed, and the anti-power wall device will no longer report to the remaining target home appliances. Send a control signal.

Fig. 3 is a schematic diagram of the process of sequentially shutting down the target household electrical appliances provided by the embodiment of the present invention. As shown in Fig. Refrigerators and smart washing machines are under the same LAN. After the smart socket detects the leakage signal of the power supply line and establishes a safe connection with the smart water heater, smart refrigerator, and smart washing machine, the smart socket first sends a control signal to the smart water heater to turn off the smart water heater, so that the smart water heater is electrically connected to the power supply line. Disconnect (indicated by a "cross" in the figure, the same below) and confirm that the leakage signal still exists according to the real-time detection of the leakage signal; after that, the smart socket continues to send a control signal to the smart refrigerator to turn off the smart refrigerator, and sends a signal to the smart refrigerator. After the control signal, the smart socket cannot detect the leakage information, indicating that the leakage accident is caused by the smart refrigerator; since the leakage phenomenon has disappeared, the smart socket will no longer send control signals to the smart washing machine, so that the smart washing machine can continue to work.

In this embodiment, when the leakage signal is detected, the candidate device identifier is obtained, and the candidate device identifier represents the device identifier of the smart device under the same local area network as the electronic device; according to the preset security configuration information, the candidate device identifier is determined. Identify the target device, and establish a secure connection with the target home appliance, where the target home appliance is the smart device corresponding to the target device identification; send control signals to each target home appliance in turn, so as to turn off each target home appliance in turn, until no longer detected to the leakage signal. Due to the security configuration information, the target device identification determined in the local area network environment indicates the indoor smart device that may cause leakage accidents. Based on the target device identification, a secure connection is established and the corresponding smart devices are controlled to shut down in turn, so as to realize the protection of the leakage device. Directional shutdown improves the leakage protection effect and response speed, and improves the safety of home appliances.

Fig. 4 is a flow chart of a method for controlling an anti-electric wall device provided by another embodiment of the present invention. As shown in Fig. 4, the method for controlling an anti-electric wall device provided by this embodiment can On the basis of the device control method, steps S102-S103 are further refined, and a step of obtaining a dynamic device connection key from the cloud server is added before S101, wherein the target household electrical appliance includes a power control interface, and the power control interface is used for Turn off the smart device. Then, the method for controlling an electric wall device provided in this embodiment includes the following steps:

Step S201, obtain dynamic security configuration information through the cloud server, and the dynamic security configuration information includes identification information and a corresponding dynamic device connection key.

Exemplarily, the identification information is used to indicate the identification of the target device, and the device connection key is an encryption parameter for establishing a secure connection based on a local area network between the firewall device and the target home appliance device. The firewall device can obtain the security configuration information from the cloud server according to a preset policy, so as to determine the target device ID among the candidate device IDs and the key for establishing a secure connection with the target home appliance. Specifically, for example, according to the preset Access to the cloud server at intervals, or receive pushes from the cloud server, or obtain security configuration information based on the subscription model, etc. This process will not be described in detail this time.

Among them, the device connection key is a dynamic key, that is, every preset period of time, the cloud service updates the key and synchronizes it to the corresponding home appliance, thereby improving the security of the smart anti-power wall for controlling the leakage of the target home appliance , to avoid illegal control of target home appliances by illegally authorized devices.

Optionally, after step S201, further include:

Step S202, scanning for device identifications of smart devices in the same local area network as the firewall device.

Step S203, according to the device identification of the smart device in the same local area network as the firewall device, and the preset security configuration information, determine the key household appliances, and establish a pre-secure connection with the key household appliances, wherein the security configuration information uses It is used to indicate the equipment identification of key household appliances.

Exemplarily, the key household electrical appliances refer to smart devices with high leakage risk or hazard, such as smart water heaters. Key household electrical appliances can be determined through user-defined configuration and other methods. Furthermore, the security configuration information also includes the device identification used to indicate the key household appliances. Before detecting the leakage signal, first scan the device identification of the smart device currently under the same local area network to determine the status of the smart device currently under the same local area network. Whether the device identifier includes the device identifier of the key household appliance, and if so, determine that the household appliance corresponding to the device identifier is the key household appliance.

Furthermore, after the key household appliances are determined, in order to avoid serious consequences caused by the leakage accident of the key household appliances, it is necessary to improve the power-off response speed of the key household appliances. The device establishes a front safety connection, which refers to the safety connection established with the smart device before the leakage signal is detected, so that the anti-power wall device and the key household appliances are always in a state of safe connection.

Step S204, when the electric leakage signal is detected, a candidate device ID is obtained, where the candidate device ID represents the device ID of an intelligent device under the same local area network as the firewall device.

Step S205, according to the identification information and the corresponding device connection key, determine the target device ID among the candidate device IDs, and establish a secure connection with the smart device corresponding to the target device ID.

Exemplarily, according to the identification information in the security configuration information and the corresponding device connection key, the target device identification specified by the identification information can be determined, and then, through the device connection key corresponding to the identification information, the target home appliance corresponding to the target device identification The device sends a secure connection request and verifies the device connection key to achieve a secure connection between the firewall device and the target home appliance. In this embodiment, by setting the device connection key corresponding to the identification information in the configuration information, the control security between the firewall device and the target home appliance device is ensured, and a secure connection between the two is realized.

Optionally, it also includes: if the smart device corresponding to the target device identifier is a key household electrical appliance, using the front-end security connection as a secure connection between the firewall device and the target device identifier.

Exemplarily, among the multiple target device identifiers, if the device identifier indicating the key household electrical appliance in the security configuration information is included, that is, there is a key household appliance among the multiple target household appliances, at this time, in order to realize the fast In response, the front safety connection of the key home appliance is used as the safety connection of the key home appliance, and the subsequent control signal is sent based on the safety connection. The secure connection established in advance, therefore, omits the step of establishing a secure connection between the anti-electric wall equipment and key household appliances, improves the speed of the anti-electric wall equipment for leakage protection of key household appliances, and realizes the security of key household appliances. Fast power off, improve the effect of leakage protection.

Fig. 5 is a schematic diagram of an anti-electric wall device provided by an embodiment of the present invention that performs power-off control on key household appliances when a leakage signal is detected. As shown in Fig. 5, the anti-electric wall device is a smart socket, and the target home appliance is Smart water heaters, smart washing machines, and smart refrigerators. Among them, smart water heaters are key household appliances. Before the smart socket detects the leakage signal, it has established a pre-safe connection with the smart water heater. When the smart socket detects the leakage signal of the power supply line, it will establish a secure connection with the smart washing machine and the smart refrigerator according to the device connection key corresponding to each target appliance in the security configuration information, and then connect the smart washing machine and smart refrigerator through the secure connection. The smart refrigerator performs power-off control (not shown in the figure); since the smart socket has established a front safety connection with the smart water heater, when the smart socket detects an electric leakage signal, the smart socket uses the front safety connection as a safety connection and directly sends to the smart The water heater sends a control signal to turn off the smart water heater to ensure rapid power-off of key household appliances.

Optionally, also include:

Step S206, determining the security connection status of each target home appliance, the security connection status is used to represent whether the security connection between the firewall device and the target home appliance is successfully established.

In step S207, according to the secure connection status of each target household electrical appliance, after determining that the secure connection with the target household electrical appliance is successfully established, a control signal is sent to the power control interface of the target household electrical appliance with which the secure connection is successfully established.

Connection abnormality alarm. The leakage protection process has high requirements for real-time response. Therefore, in order to avoid the real-time problem of leakage protection caused by the failure to send control in time due to the abnormal safety connection, the anti-electricity wall device first determines the safety connection status with the target home appliance. After it is determined that the secure connection with the target household electrical appliance is successfully established, a control signal is sent to the power control interface of the target household electrical appliance that successfully establishes the secure connection. In this way, the real-time problem of leakage protection caused by multiple attempts to send control signals is avoided. Optionally, when the anti-electric wall device determines that it cannot establish a safe connection with the target home appliance, it can send an alarm through a speaker or send an alarm message to inform the user that there is a leakage but cannot perform automatic leakage protection, and remind the user Perform manual processing to improve the effectiveness and safety of leakage protection.
