Application case of Che’an Technology Vehicle Guidance System in Tianjin West Railway Station
chrispeng [ad_1]
There are 963 parking spaces in Tianjin West Railway Station, including 443 parking spaces in the South Plaza, 280 parking spaces in the North Plaza, and 240 parking spaces in the control center. In order to provide car owners with a safer, more comfortable, convenient and fast parking environment, the car-safe vehicle guidance system is adopted in the parking lot system to realize the high-efficiency, energy-saving and environmental protection of the parking lot.
Vehicle guidance system
The vehicle guidance system consists of workstations, communicators, vehicle guidance controllers, parking detectors (ultrasonic probes) and location guidance display devices. The system monitors the situation of the parking spaces at any time and transmits the data to the vehicle guidance control system. The computer collects and processes all the data, and then sends out control signals to the guidance and indication screens to guide each car to find the vacant space on the nearest path, and record it at any time Vacancy rate changes. The counting of vehicles is realized by ultrasonic detectors.
1.Traffic flow detection function
The vehicle flow detection system is used to detect the number of vehicles entering and exiting the entrance and exit of the parking area and the entrance and exit of each parking area. The data is sent to the main controller in real time through the data collector and node controller, and the main controller updates the guide screen of each entrance in time through calculations. There are vacant parking spaces and guide customers to park. This system is composed of vehicle detectors, dedicated infrared beams, controllers, data collectors, etc. It has the functions of flow detection, retrograde detection and car following detection, and can accurately determine the direction of the vehicle and the number of vehicles passing by.
The traffic detector detects the vehicles entering and exiting the parking lot, including the vehicles parked in the parking space and the vehicles driving in the parking lot. If only the parking space detector detects the number of vehicles, it is impossible to accurately count the actual number of vehicles in the parking lot.
2.Automatic parking guidance function
The system has an automatic parking space guidance function. After the vehicle enters the field, the owner can quickly find the empty parking space through the information display system on the channel to display the vacancy of the parking space in each area.
3.System control and self-check function
The system updates the number of parking spaces on each guide screen in real time, uploads the data to the management computer in real time, and visually reflects the usage of parking spaces on the electronic map. The control system can work independently after setting the parameters through the boot system software. At this time, the computer shutdown or failure will not affect the system functions. The control system is composed of a main controller, a node controller, and a data collector. It collects the status of the parking space detector and the traffic flow detector in real time, performs calculations on the number of parking spaces, and sends the calculation results to the guide screen and the management computer. The control system has a self-inspection function, which sends out alarm information to faulty equipment to indicate equipment failure. The specific location can be found through the management software, which is convenient for maintenance personnel to carry out system maintenance.
4. Boot the system management software
The boot system management software has the following functions:
◆Electronic map shows the status of parking spaces
◆Parking overtime alarm and equipment failure alarm
◆VIP parking management
◆Event record table
◆History table
◆Administrative Management
5. Chart report form
In this interface, you can enter various function menus to operate, and perform system settings, data query, report printing, data maintenance, etc. according to different needs. After the operation is completed, return to this interface.
When the system is working normally, the parking space on the electronic map will be displayed according to whether the parking space is occupied or not. If there is a car in the parking space, the parking space will be set to red, which is convenient for managers to understand the usage of the parking space. In the information bar on the left side of the interface Display the total parking space usage of the parking lot, such as the total number of parking spaces, the number of empty parking spaces, etc.
In addition, for some parking spaces actually occupied by Chang, an alarm message will be issued, and the position of the parking space will be displayed in the box at the lower left corner of the interface, and the display will remind the system manager to pay attention to whether there is any abnormal situation.
