When the ultrasonic parking space detection device is used, when a vehicle drives into an idle parking space, the ultrasonic parking space detector detects that the idle parking space is or has already parked the vehicle and then sends acquired parking space parking information to the node controller, the node controller collects the information that the parking space is or has already parked the vehicle and then uploads the parking information to the central control module and sends a control signal to the wireless sensor, and the wireless sensor cuts off the power supply of the spotlight after receiving the control signal sent by the node controller, so that the spotlight is automatically extinguished when the vehicle is parked, the existing vehicle in the parking space is conveyed to a vehicle owner, the vehicle owner can conveniently select a proper idle parking space, the vehicle parking time after the vehicle enters the parking lot is shortened, and the parking efficiency of the parking lot is improved; when the vehicle leaves the parking space, the ultrasonic parking space detector detects that the parking space of the parked vehicle is in an idle state and then sends the collected parking space parking information to the node controller, the node controller sends a control signal to the wireless sensor, and the wireless sensor controls the spotlight to be lighted.
As an embodiment of the present invention, the system further includes a network adaptor, wherein the network adaptor is configured to analyze data flowing between the LORA wireless control module and the central control module, obtain information on the number of vehicles detected by the wave frequency vehicle detector at each exit of the parking lot, and send a control decision for controlling the route of the vehicle leaving the parking lot to the LORA wireless control module according to the information on the number of vehicles.
When in use, in the parking process of vehicles in a parking lot, because the network adapter is internally provided with network data monitoring, the network adapter analyzes data flowing between the LORA wireless control module and the central control module, analyzes the information of the number of vehicles detected by the wave frequency vehicle detector at each exit of the parking lot, compares the information of the number of vehicles waiting for going out according to the information of the number of vehicles waiting for going out at each exit of the parking lot to obtain an exit of the parking lot with less number of vehicles waiting for going out, sends the exit position with less number of vehicles waiting for going out of the current parking lot to the central control module through a wireless broadband ad hoc network, sends the position planning information to the LORA wireless control module after receiving the position, sends the direction indicator light information related to path planning to the intelligent signal controller by the LORA wireless control module, and controls the direction indicator light to change by the intelligent signal controller, for example, the left-turn green, the straight-going green and the right-turn green are changed into the left-turn red, the straight-going red and the right-turn green, so that the vehicles needing to drive away from the parking lot are induced to rapidly drive to the exit with a small number of vehicles waiting for going out, the blockage avoiding measures in the parking lot are realized, the unobstructed degree of the roads in the parking lot is promoted, the parking efficiency in the parking lot is improved, and the excessive blockage at the entrance and the exit of the parking lot is avoided.
The specific working process is as follows:
when a vehicle parks in a large urban underground parking lot, a vehicle owner can select whether to drive into the parking lot according to the parking space condition of the underground parking lot shown by an outdoor guide screen, the vehicle drives into a camera in an outdoor module to take a picture of the vehicle, then the vehicle drives into the underground parking lot, a parking space detection module collects real-time free parking space data in the parking lot and feeds the collected data back to a central processing module through RS-485 communication, the central processing module processes the free parking space data collected by the parking space detection module and feeds the data back to the outdoor guide screen to display free parking space information, so that the vehicle owner can know the free parking space information in the parking lot in real time and conveniently enter the parking lot to park; under the condition that a lot of vehicles are driven into an urban parking lot, when the vehicles are driven into a main road in an underground parking lot, when the vehicles approach a guide module, the guide module detects the number of the vehicles on the main road, and sends information to a central processing module in an RS-232 communication mode, a parking space detection module feeds back the information of the current idle parking space to the central processing module through RS-485 communication, the central processing module matches the data sent by the guide module with the data fed back by the parking space detection module so as to match the information of the specific parking space of the vehicles currently driven close to the guide module at the near-far parking distance, the central processing module sends the information of the specific parking space into the guide module in an RS-485 communication mode, and the guide module induces the current vehicles to drive to the idle parking space according to the plan of the central processing module by displaying direction signals, until the vehicle drives into the vacant parking space preset by the central processing module, the vehicle in the parking lot can rapidly and orderly drive into the parking space; when a vehicle drives into a parking space, the parking space detection module senses that the detected parking space is parked into the vehicle, the parking space detection module collects parking information of the parking space and feeds the information back to the central processing module through RS-485 communication, and the central processing module screens out the parking space when subsequently pairing vehicle parking data after receiving the information; when a parked vehicle exits from the parking lot from the parking space, the parking space detection module senses that no vehicle is parked in the current parking space, so that the information of the idle parking space is sent to the central processing module, and the central processing module is enabled to carry out vehicle parking pairing.
