A three-dimensional parking lot is a new type of parking lot that fully utilizes urban space, maximizes utilization, and saves urban land. At the same time, the parking environment in the parking lot is relatively complex, and car owners cannot quickly find empty parking spaces when entering the parking lot, wasting parking time. At the same time, it is easy to cause congestion in the parking lot and scratches between vehicles.

The three-dimensional garage parking space guidance system is equipped with a wireless ultrasonic parking space detector in the center of the parking space iron plate to obtain parking space status information. A parking space indicator light is installed above each group of garages, and the wireless detector uploads the status of the parking space to the corresponding wireless parking space indicator light of the group of garages through wireless communication in real time. The parking space indicator light collects all parking space status information of the group of garages, and when there are empty parking spaces in the three-dimensional garage, the indicator light displays green, and when there are no empty parking spaces, the indicator light displays red; The wireless parking indicator lights encode the information of the group of three-dimensional parking spaces and upload it to the wireless node controller. The central controller collects all node controller data information, completes data processing, and updates the remaining number of parking spaces displayed on the parking guidance screen in real time, thereby achieving the function of guiding vehicles into empty parking spaces. The system simultaneously transmits data to the computer, which stores the data on the database server. Users can query real-time parking space information and annual, monthly, and daily statistical data of the parking lot through the computer terminal.

The three-dimensional parking space guidance system can be compatible with front mounted and split type ultrasonic guidance systems, meeting the needs of mixed parking lots with ordinary parking spaces and mechanical parking spaces.

Ground mounted ultrasonic parking detector

The ground mounted parking spot detector is an important component of the three-dimensional garage parking spot guidance system, installed in the middle of each parking spot iron plate. It uses the working principle of ultrasonic distance measurement to obtain parking spot status information, and uploads the parking spot status to the corresponding wireless parking spot indicator light of this group of garages in real time through wireless communication. The parking spot indicator light collects all parking spot status information of this group of garages, determines whether there are empty parking spots in this group of garages, and displays the corresponding color status to guide car owners to stop. All parking spot information is uploaded to the wireless node controller through wireless communication.
