Abstract
The design of the current car park management system for the medium backward management system, integrated low degree of automation, poor security, human and operational inefficiencies of inadequate in light of the current field of science and technology as research results, design a more advanced technology, Reliable performance, a higher degree of automation Smart car park management system. The design of the guiding ideology based on the improved car park management system reliability, safety and efficiency of China's major cities in the face of "difficult to stop" the settlement of the issue, have a certain role. The system used by the PLC technology, RF card technology to other transport system has some reference.
This paper car park can only control system problems that exist in the PLC PLC and inverter control system can only be used in car parks, and a more in-depth studies.
In this paper, the Intelligent Parking Systems PLC control, charging, billing and security of some of the basic ideas and methods, and gave a briefing on the work focused on the PLC and operating characteristics of principle, also introduced C20P-Omron programmable control Series of C200H-OA223 PLC controller main function modules and application, C20P programming not only simple, high universality, anti-interference capability and high reliability, but also easy to operate and maintain, design, construction, commissioning the advantages of short cycle . It also introduced the MIFARE1ICS50 contactless IC card of the structure, describes the car park management system and the function of the basic modules, and the main circuit and control circuit for the hardware part of the detailed briefing. This article is a car park intelligent design, through the adoption of PLC technology on the design of car park management to car parks intelligent, efficient.
