Parking lot management system of PLC control

Abstract

The invention provides a parking lot management system of PLC control. The system comprises an IC card reader, a computer system, a PLC, a parking stall display board, a barrier-gate front inspection module, a barrier-gate rear inspection module, a parking stall sensor and a barrier gate. The computer system is formed by a computer, a communication line and configuration software and is used to mainly complete functions of IC card verification, temporary parking IC card management, control signal receiving and sending, data statistics and form printing. When receiving a control signal of a central computer, the PLC controls opening and closing of the barrier gate. The barrier-gate front inspection module and the barrier-gate rear inspection module are used to realize an anti-smashing vehicle function, which means that when the vehicle is under the barrier gate, a brake bar does not drop; and after the vehicle is left, the brake bar is automatically dropped. According to the control signal sent by the central computer, the PLC control makes logic determination and a corresponding parking stall navigational lamp is opened on the parking stall display board. The parking stall sensor sends a signal that the vehicle arrives at an assigned parking stall to the central computer and the central computer displays parking stall state information.

Description

technical field [0001] The invention relates to a parking lot management system, in particular to a PLC-controlled parking lot management system. Background technique [0002] With the development of social economy and the improvement of people's living standards, owning a private vehicle is no longer an unattainable dream. At present, more and more families or individuals own vehicles. But it has become a thorny problem for drivers to face. Therefore, solving the difficulty of parking has become a problem that the property management of the community must first consider. Whether it is a new residential area or a new public building, a certain scale of parking lot must be considered, and the corresponding parking lot management system has been more and more widely used. Advanced technology and highly automated electromechanical equipment are used to integrate machinery, electronic computers Organically combined with automatic control equipment and smart IC card technology, ...

AI Technical Summary

Problems solved by technology

However, at present, if some small parking lots in some communities want to use a lot of high-tech, there will be problems of insufficient funds, imperfect maintenance and management, and sometimes the consideration is not comprehensive enough. Therefore, it is necessary to solve the problems of high vehicle management costs and low service efficiency.
