to the project site drawings for the design of system functions based on the current international system, Introduction to the induction of advanced IC card technology and automated control technology for vehicle management and control of parking fees. Out of the parking lot owners through the computer automatically recognize the identity of the cardholder, or block the release of mac brushes to determine charges. First, the system features: 1, using the centralized control system uses a network structure with high reliability, low maintenance industrial bus RS-485 bus interface, the system main equipment are used RS-485 interface to connect to the system bus, connected to the bus insanity workout by the same on the host computer to receive information about each device and operating instructions issued by the device. Thus, the complexity of the system is small, easy to maintain equipment, systems engineering and low cost. System uses the RS-485 bus interface connectivity than 1 km distance, and, the control computer through LAN interconnection, has good scalability. The entire system without supplies, low cost and easy maintenance. 2
, the use of non-contact inductive sensor reader mac makeup access control system technology is successfully applied to high-level non-contact reader technology, the system operational safety, reliability and maintainability are fully guaranteed. Sensor reading distance can be close to (passive 5-20cm ) can be far (active 1-15m ), according to user needs in any combination, extremely easy to use. Induction card, long life, easy to use, computerized management system to make north face denali more simple and convenient parking lots. 3, reliable, and efficient use of national patent brakes, full stretch balanced, low-power, no wear, effectively extending the service life, with the sense coil, the vehicle down automatically after a gate, smashed cars with anti-function. 4
