The present invention also discloses the working method of the above-mentioned intelligent parking management system based on the Internet of Things, the method is as follows:

When a vehicle passes the location of the RFID high-frequency reader at the entrance checkpoint, the RFID high-frequency reader reads the card number of the vehicle, and then passes the number of the parking area and the read card number through the Zigbee terminal node of the entrance checkpoint Send it to the Zigbee coordinator node in the vehicle information management center, and then the Zigbee coordinator node will pass the data information to the central control system for processing through the RS232 interface, and start recording the dwell time of the entering vehicle;

When a vehicle passes the position of the RFID high-frequency reader at the exit checkpoint, the RFID high-frequency reader reads the card number of the vehicle leaving, and then passes the number of the parking area and the read card number through the Zigbee at the exit checkpoint The terminal node sends it to the Zigbee coordinator node of the vehicle information management center, and then the Zigbee coordinator node passes the data information to the central control system for processing through the RS232 interface, and stops timing the vehicle residence time corresponding to the card, and at the same time, according to the vehicle stay time The time record calculates the parking fee and completes the update of the system management information;

The vehicle information processing center receives and processes the information sent by the entrance checkpoint and the exit checkpoint. When receiving the information sent by the entrance checkpoint, it means that a vehicle has entered the parking lot, and starts to record the parking information of the vehicle, including the parking area number of the vehicle. , card number and time information; when the information sent by the exit checkpoint is received, indicating that a vehicle has left the parking lot, stop recording the vehicle’s residence time, and calculate the parking fee that the driver should pay according to the recorded result, and clear the corresponding record.

Beneficial effect: compared with the prior art, the present invention has the following advantages:

The intelligent parking management system based on the Internet of Things described in the present invention combines the RFID radio frequency identification technology of the Internet of Things system, the Zigbee wireless communication technology and the basic flow of parking management in the parking lot to realize the integration of the Internet of Things technology into the traditional parking lot. In the car management system, accelerate the pace of modernization of the intelligent parking management system in the parking lot, improve the efficiency of the parking management in the parking lot, and facilitate the quick and convenient parking of the car owner.

Detailed ways

Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

Example

The intelligent parking management system based on the Internet of Things as shown in the figure includes: entrance checkpoint, exit checkpoint and vehicle information processing center; described entrance checkpoint and exit checkpoint include: RFID high-frequency reader and connected with it Zigbee terminal node; Described vehicle information processing center comprises: central control system and Zigbee coordinator node; Described central control system adopts the S3C2440 chip of ARM9 framework as central processing unit, and carries out data interaction with ZIGBEE coordinator node by RS232 interface.

The working method of the above-mentioned intelligent parking management system based on the Internet of Things is as follows:

When the vehicle enters the parking lot, the driver receives a radio frequency identification card. When the vehicle passes the RFID high-frequency reader at the entrance area, the machine reads the radio frequency identification card number. The serial number is "0X0B". If the vehicle passes the position detection of the entrance checkpoint in zone B, the serial number in this zone and the read card number will send "0X0B" + "card number" to the Zigbee coordinator node of the vehicle information management center through the Zigbee terminal node information; then detect that the landing pole at the entrance of the area is raised, and the vehicle can drive into the park, and the system starts to record the residence time of the entering vehicle; when the vehicle leaves, the vehicle will pass through the exit checkpoint, and the driver swipes the card again, for example, In area B, the number of the area and the read card number will send "0X0B" + "card number" information to the Zigbee coordinator node of the vehicle information management center through the Zigbee terminal node, and the system will stop recording the residence time of the leaving vehicle , and calculate the parking fee according to the time record of the vehicle's stay, so as to complete the update of the system management information. Finally, the landing lever at the exit of Area B is raised, and the driver drives away from the parking area.

In this embodiment, during the system operation, the vehicle stay information record is realized by the timing mark bit and the stay time value; when the Zigbee coordinator node of the information processing center receives the card number sent by the Zigbee terminal node of the entry checkpoint, the corresponding corresponding The timing flag of the card, when receiving the card number sent by the Zigbee terminal node of the exit checkpoint, then clear the timing flag of the corresponding card; the information processing node will check the timing flags of all cards every 1 second, if If the flag bit is 1, add 1 to the time record value of the corresponding card, otherwise clear the time record value of the corresponding card. In this way, it is possible to record the parking time of vehicles in the parking lot in seconds.
