（1）、 System Overview

The ultrasonic parking guidance system is an intelligent parking lot parking monitoring and guidance management system. The system relies on ultrasonic detectors installed above each parking space to collect real-time information on the occupancy and idle status of the parking space. The supporting parking guidance controller summarizes the front-end equipment data in a polling manner and transmits it to the data center for processing through a high-speed bus. Finally, real-time parking data will be synchronized to the on-site LED guidance screen, accurately guiding car owners to quickly find available parking spaces, effectively reducing search time and alleviating traffic congestion in the venue. This system is suitable for various indoor parking lots such as urban complexes, shopping malls, office buildings, and parks. It can provide efficient, convenient, and comfortable parking services for car owners, and comprehensively improve the digital and intelligent operation and management level of parking lots.

（2）、 Core functions and product features

1. Minimalist communication, reducing costs and increasing efficiency

Support power line carrier communication mode, relying on existing power lines to achieve data transmission, without the need to lay a large number of communication pipelines, greatly simplifying the construction process, reducing project wiring and later operation and maintenance costs. Simultaneously adopting RS485+TCP/IP dual layer network architecture, combining the advantages of half duplex and full duplex communication modes, balancing the high-speed and stable data transmission, streamlining equipment nodes, and significantly improving the overall anti-interference ability and operational reliability of the system.

2. Easy installation and strong adaptability

Equipped with industrial grade wireless ultrasonic detectors, it completely solves the pain points of cumbersome wiring and difficult construction in traditional mechanical three-dimensional garages and irregular parking spaces. The equipment does not require redundant cable trays for wiring, with flexible installation and convenient maintenance in the later stage. It is suitable for various conventional parking spaces and mechanical mixed parking spaces.

3. Global compatibility and unified management

The system communication protocol has strong compatibility and can achieve seamless integration of wired and wireless devices. It supports integrated control of mixed scenarios of ordinary flat parking spaces and mechanical three-dimensional parking spaces, breaking down barriers to scene adaptation and adapting to diversified parking lot layouts.

4. Real time monitoring and data visualization

It can monitor the status of all parking spaces in real-time 24 hours a day, automatically count the number of occupied and vacant parking spaces, accurately record the entry and exit data of vehicles at each time period, generate basic parking lot operation data reports, and provide accurate data support for management personnel to monitor the parking lot status, coordinate scheduling, and analyze operations in real time.

5. Flexible configuration and high scalability

All terminal devices are equipped with independent address coding to form a standardized grid network architecture. Management personnel can flexibly adjust the correlation logic between the terminal and the guidance screen through the supporting guidance software, with simple parameter configuration and convenient operation, suitable for scenarios such as parking space renovation and area expansion in the later stage of the parking lot.

6. Offline independent operation, high stability

The system adopts a software hardware separation operation mode, and the PC side is only responsible for parameter configuration and basic data storage, and does not participate in core businesses such as real-time guidance of the parking lot and parking space monitoring. The equipment can operate independently and stably without the computer, avoiding system crashes caused by computer failures or shutdowns, and ensuring the normal operation of the parking lot 24/7.

7. B/S cloud architecture, convenient operation and maintenance

The management platform adopts mainstream B/S architecture, and the system main program is deployed on the server side. Management personnel do not need to install dedicated clients, and can log in to the background anytime and anywhere through a browser to view yard data, manage equipment, and adjust parameters. System upgrade and maintenance only require server operation, without the need for end-to-end debugging, greatly reducing the difficulty and cost of operation and maintenance.

8. Multi functional linkage, intelligent control

The parking controller is equipped with two relay output interfaces, which can flexibly connect to supporting equipment such as traffic lights, parking indicators, and barrier gates to achieve linkage functions such as parking status light prompts and traffic control at the entrance and exit of the parking lot. It builds an integrated intelligent parking control system and improves the level of precision in parking lot management.
