Background technique

With the continuous development of economy and society, the scale of cities continues to expand, and the number of motor vehicles also increases rapidly. The surge in traffic flow has brought great pressure to urban road traffic. The overall traffic flow in many urban areas has been in a state of heavy load, especially during the rush hour, many road sections are prone to frequent traffic congestion, coupled with occasional traffic incidents, seriously affecting people's travel efficiency, even It causes people to misunderstand the administrative inaction of traffic managers and brings about social problems.

In order to solve the traffic jam phenomenon, intelligent traffic guidance system came into being. Currently there are many solutions, generally based on GPS or Beidou satellite vehicle navigation system, but also rely on a powerful traffic road network information system to provide real-time and accurate traffic road condition information. Lack of standard interfaces and compatible protocols, application promotion rate and operation effect are not high.

Detailed ways

The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

RFID is the abbreviation of radio frequency identification in English, which means radio frequency identification. This is a non-contact automatic identification technology. The identification of the target object can be completed by two components: an electronic chip and a reader. WeChat is a free application platform for smart terminal instant messaging with a large number of users. It provides functions such as a public platform, circle of friends, and message push, and supports voice SMS, video, picture, and text transmission.

As shown in accompanying drawing 2, the system that adopts in the present embodiment comprises several parts such as RFID electronic chip, RFID reader, information processing equipment, the central server (comprising database) that supports WeChat and driver's smart phone.

Each RFID electronic chip has a unique electronic code, and the vehicle information is recorded in the chip; and the vehicle driver's smartphone number and WeChat ID are associated with the vehicle's RFID information and stored in the database of the system center;

The information processing equipment is usually installed in the electrical box on the side of the road, and is connected and communicated with the RFID reader through cables.

The system center server is installed in the central computer room of the urban intelligent traffic guidance system, and is connected with the information processing equipment of each road section through a gateway or a router in the form of optical cables or cables.

The overall implementation of this embodiment is carried out according to the flow process of accompanying drawing 1. As shown in accompanying drawing 3, present embodiment is applied in intersection:

a. The urban traffic management department applies for an intelligent traffic guidance system WeChat public platform, and the vehicle driver applies for a subscription number of the urban intelligent traffic guidance WeChat public platform, becomes a member of the intelligent traffic guidance WeChat circle, and logs in to the WeChat platform with a smartphone.

b. The urban intelligent traffic guidance system is networked with the urban road traffic monitoring system to realize information sharing; the central server of the urban intelligent traffic guidance system can retrieve video, pictures, text and other information in the urban road traffic monitoring system at any time.

c. Install RFID chips on all vehicles in the urban intelligent traffic guidance system, and the RFID chips record vehicle information; the vehicle driver's smartphone number and WeChat number are associated with the RFID information of the vehicle and stored in the intelligent traffic guidance system database; the center The server can access the database at any time.

d. Install the first RFID reader at the east, south, west, and north four sections of the urban road intersection, and install the second RFID reader at the same direction section opposite the intersection; all RFID readers are respectively electrically connected to the information processing equipment.

e. Define an address recognizable to both the RFID reader and the information processing device for each of the four road sections, and write the address into the first RFID reader and the second RFID reader corresponding to the four road sections.

f. When a vehicle equipped with an RFID chip passes through the reading range of the first RFID reader, the first RFID reader reads the RFID code of the vehicle and transmits the RFID code and the address corresponding to the road section to the information Handle equipment.

g. After the information processing device receives the RFID code and road section address sent by the first RFID reader, it determines which road section the vehicle corresponding to the RFID is located in, and stores the vehicle information in the information processing device.

h. When a vehicle equipped with an RFID chip drives straight ahead or turns to a certain direction through an intersection, and passes through the reading range of the second RFID reader, the second RFID reader corresponding to the direction reads the RFID of the vehicle Encode and transmit the RFID code and the address corresponding to the road section to the information processing device.

i. The information processing equipment analyzes and judges the forward direction and current route of the vehicle based on the information such as the RFID code and the road address, and transmits the information such as the RFID code, the road address, the forward direction and the current route of the vehicle to the system center server; after that, the information processing device deletes the information to make storage space for subsequent applications. For example, when a vehicle traveling from east to west reaches a crossroad, the first RFID reader 1 (1) first reads the RFID information of the vehicle and transmits the information to the information processing device; after that, the vehicle may select There are three different driving directions: going straight, turning right, and turning left. According to different driving directions, the second reader 1 (2), the second reader 4 (8) and the second reader 2 (4) will respectively record the Vehicle information, and transmit the information to the information processing equipment. The information processing equipment synthesizes the information of the first RFID reader 1 (1) and the second reader 1 (2), and judges that the vehicle is going straight; according to the first RFID reader 1 (1) and the second reader 4 (8) or The information of the second reader 2 (4) judges that the vehicle is turning right or turning left. It is also possible that the second RFID reader 3 (6) may mistakenly read the vehicle information traveling westward on the east side of the intersection, which belongs to the repeated information of the RFID reader on the same road section, and the information processing equipment judges it as meaningless information and directly deletes it.

j. The system center server queries the information in the database of the intelligent traffic guidance system, and finds the vehicle driver's smartphone number and WeChat account corresponding to the RFID code.

k. The system center server, according to the priority of the vehicle's straight line direction and the order of the turning direction, sequentially retrieves the video, pictures and other information of the RFID codes corresponding to several intersections or ramps on the vehicle's forward route from the urban road traffic monitoring system , through the WeChat platform, corresponding to the micro-signal sent to the vehicle driver registration; the situation of important intersections is sent to the driver's WeChat code in text; Passengers go straight or detour other sections of the road. In order to improve the timeliness and save hardware resources, it is suggested that the voice of the driving route can be sent to the vehicle drivers on the relevant road sections in the form of WeChat announcements.

l. According to the video, picture, text, voice and other information provided by the WeChat platform, the driver of the vehicle can avoid road traffic congestion. He can choose to go straight all the way or go straight first and then turn at the next intersection.
