　　RFID technology parking space detection system working principle

　　The intelligent parking lot management system includes automatic entry and exit recognition of vehicles at entrances and exits, parking space detection and positioning, intelligent guidance and reverse car-finding subsystems. When vehicles enter and exit the parking lot, the low-frequency coils buried in the entrance and exit activate the Dual-frequency electronic tag, the tag actively sends the tag ID and coil address code, which is read by a long-distance 2.4G card reader, connects to the controller, and controls the opening and closing of the gate to achieve non-stop access management.

　　The intelligent vehicle guidance system provides data for parking space guidance according to the real-time status of parking spaces provided by the parking space detection system, and sends the data to the main controller and management computer in real time through the data collector and node controller, and the main controller updates each intersection in time The number of empty cars on the guide screen guides customers to stop. At the same time, the parking space indicator is controlled to display different colors according to the usage of the parking space. Red is occupied and green is vacant. Customers can see it from 50 meters away. According to the color of the parking indicator, customers can quickly find a parking space.

　　The reverse car search system detects and locates the parking space according to the dual-frequency electronic tag on the vehicle. Under the premise of vehicle positioning, the system records the location information of the vehicle. When returning to the parking lot to search for the car, the guest queries the vehicle. The location operation is simpler, just find a query terminal nearby, directly read the ID representing the vehicle's identity for query, the display will show the parking space information corresponding to the voucher, such as "B1 floor, A08 zone". You can quickly guide the guests from a huge blank space to a relatively small area. In this small area, for most guests, finding their own car is no longer a problem. This is achieved. The intelligent process to help guests find a car. It can also be combined with the built-in electronic map in the query terminal to automatically generate a road map in real time to help customers find their vehicles easily and quickly.
