I. Introduction
At present, the company’s vehicles are managed manually. When a vehicle enters or exits the company, it is necessary to manually control the automatic retractable door. Whenever a foreign vehicle enters or exits the company, the administrator can only register one by one. When there is human error. It is no longer sufficient to rely on traditional vehicle monitoring and management to ensure timely and effective records of entering and leaving the company’s vehicles. In this regard, we use RFID radio frequency technology to manage the company’s vehicles. This system allows the guards to monitor the vehicles in real time, saving the time of vehicle entry and exit, and greatly reducing the management work intensity.
2. System Principle
1. Label initialization
First, install an RFID electronic tag on the front windshield of the vehicle, and enter the vehicle information and personnel information corresponding to the tag into the software.
2. Vehicle access and monitoring management management
When the vehicle arrives at the entrance, the entrance ground sensor senses the vehicle. At this time, the system starts monitoring and starts to work, and the reader starts to read the electronic tag. If the read tag is registered in the system, the control panel starts the retractable door to open the door. When the vehicle arrives above the ground sensor inside the door, the ground sensor confirms that the vehicle has passed the retractable door, and the system software sends the retractable door closing signal to the control panel, and the reader and monitor also stop working. Conversely, it is the same process when the vehicle leaves the company.

4. Handling of special circumstances
A. Follow the car, pass in the opposite direction, and pass in and out of foreign vehicles
When there is a car passing by the ground, the system starts to work and monitors the implementation of the capture to enter the vehicle. At this time, the door guard also needs to always pay attention to whether the entering and exiting vehicles are labeled with our company. At this time, the reader starts to continuously scan the vehicles within a specific range. The read label system software will be automatically compared with the background database. If the label information is consistent with the background database information, the sensor door will open automatically; the key to solving the following and oncoming vehicles is the count and ground sense of the reader If the number of times read by the reader does not match the number of ground sensing, it means that there are foreign vehicles in it; at this time, the system will alarm; the sensing door is only when the number of times read by the reader and the number of ground sensing When it matches, the door will be closed automatically.
B. In and out of foreign vehicles
For foreign vehicles, the administrator needs to perform card issuance registration procedures for them. All vehicles are recorded by the system. After the card is issued, the personnel of foreign vehicles need to swipe the card once before exiting the system and alarm.
3. System advantages
1. Save manpower, improve work efficiency and economic benefits
2. Automated design, fast entry and exit of vehicles, improved grade and efficiency, and provided high-quality, safe and automatic parking services
3. Can accurately distinguish between free vehicles and foreign vehicles
4. Show the company’s integration strength
