System Structure
Through the split ultrasonic parking space detector installed directly above each parking space, the parking space information of each parking space in the parking lot can be collected in real time. When a vehicle is parked in the current parking space, the parking space indicator directly above the parking space line changes from green to red. The area controller connected to the detector will collect the information of each connected detector according to the polling method, and will compress and encode the data according to certain rules and then feed it back to the central controller. The central controller will complete the data processing, and The processed parking space data is sent to each parking space guide screen of the parking lot to display the vacant parking space information, so as to realize the function of guiding the vehicle into the vacant parking space. The system transmits the data to the computer at the same time, and the computer stores the data in the database server. The user can query the real-time parking space information of the parking lot and the year, month, and day statistical data of the parking lot through the computer terminal.
Split-type ultrasonic parking space guidance topology map Split-type parking space guidance, separate the ultrasonic probe from the indicator light. The detector is installed directly above the middle of the parking space, and the split indicator light is installed directly above the front of each parking space line to collect parking space status data in real time, and control the parking space indicator to display red, green or blue according to the full empty status of the parking space.
Features

Split Ultrasonic Parking Space Detector
The Split Ultrasonic Parking Space Detector is a core detection component of the parking guidance system. It consists of a separate ultrasonic sensing unit and a parking indicator light, designed to accurately monitor individual parking space occupancy and provide clear visual guidance.
The ultrasonic probe is installed above the center of each parking space, while the indicator light is mounted in front of the parking space line. Using ultrasonic distance measurement technology, the detector continuously collects real-time parking occupancy data and transmits the information to the area controller via RS485 communication.
When a parking space is vacant, the indicator light displays green. When occupied, it switches to red. Blue indicates fixed parking spaces, and purple indicates reserved parking spaces. Multiple color configurations are supported to meet different parking management requirements.
