Ultrasonic parking sensor guidance system for indoor parking lot

Ultrasonic with LED indicator all-in-one parking sensor guidance system used for indoor basement parking lot 

Through the front-mounted ultrasonic parking space detector installed directly above each parking space line, 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 indicator light integrated with the front-mounted ultrasonic parking space detector 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 according to certain rules, the data will be compressed and encoded and then fed back to the central controller. The central controller completes the data processing, and The processed parking space data is sent to each parking space guide screen of the parking lot to display the empty parking space information, so as to realize the function of guiding the vehicle into the empty parking space. The system transmits data to the computer at the same time, and the computer stores the data to the database server. The user can query the real-time parking space information of the parking lot and the year, month, and day statistics of the parking lot through the computer terminal.

2.Node Controller

The node controller cyclically detects the status of the connected detectors and uploads the relevant information to the central controller. We recommend that each node controller be connected to control up to 62 terminals.

The node controller is used to connect the central controller and parking detectors, LED display screens, etc., using RS485, CAN bus hybrid communication mechanism, to solve the problem of unreliable long-distance communication, network node expansion, group management, etc.

3.Central controller

The central controller is the core of the entire system, and is the collection and control center of the entire intelligent parking guidance system. It realizes the guidance function of the vehicle by updating the real-time data of the parking guidance screen. A central controller can control up to 62 node controllers.

4.Indoor LED Display

A parking guidance display screen is installed at important intersections in the parking lot. The guidance screen is composed of high-brightness LED modules, drive units, brackets and other parts. It receives the output information of the centralized controller, displays the number of empty parking spaces in the area in the form of numbers, arrows, etc., guides car owners to find empty parking spaces quickly, and ensures unblocked parking and full use of parking spaces.

5.Outdoor Guide LED Display

A large parking guide screen is installed at each entrance of the parking lot to display information about the remaining parking spaces in the parking lot. The display screen is composed of high-brightness LED modules, drive circuits, brackets and other parts. It receives the parking statistics information of the centralized controller, and displays the current number of empty parking spaces in the parking lot in numbers and texts in real time, prompting the vehicle drivers who are ready to enter. Use it 24 hours a day.
