What is the components of a ultrasonic parking guidance system

The ultrasonic parking guidance system is mainly used to guide the vehicles that need to park, so that the vehicles can enter the destination parking space smoothly. Generally used in parking lots, it is convenient for parking people to park, making parking lot management standardized and orderly, and it is a powerful supplement to the intelligent parking lot system.

The working principle is as follows. First, an ultrasonic detector is installed on each parking space, and then ultrasonic detection technology is used to detect the parking space. It can detect whether the parking space is free, and send the data to the processing center. The information is output through the processing center. Feedback to each indicator display.

From the above, we can roughly see that the parking space guidance system consists of three parts, as follows.
1. Data acquisition system
The parking guidance system installs an ultrasonic probe directly above each parking space, and connects the probe to the probe controller through the RS485 bus. The probe controller summarizes and processes the collected information, and then connects to the collection terminal through an RS485 bus. The acquisition terminal transmits the information of each parking space to the data processing center through the CAN bus, and the data center transmits the data to the management computer in real time, and the computer analyzes and processes the data. Here, the data center can also transmit the data to the collection terminal, and the collection terminal can send the information to the empty parking space display screen for parking guidance.

2. Central processing system
Central processing mainly analyzes the collected data and transmits it to the corresponding display device, mainly in the following aspects;
1. Use the management computer to publish relevant data to the local area network;
2. It can transmit data to the city parking guidance system control center through GSM and wireless MODEM.
3. Publish the parking space data in the parking lot.

3. Output display system
In this part, the common ones are the display screen and the guiding license plate, which constitute the transmission display system. The central processing system analyzes and processes the collected information and sends it to each display screen to display parking space information and provide parking guidance.
