Distributed control system of lifting and transferring parking device

Abstract

An overall control system used by the existing lifting and transferring parking device has the disadvantages of large scale, multiple connection cables, complex control, high cost, special design, difficult standardized production, difficult installation and construction, inconvenient maintenance and the like. According to the invention, a distributed control system is composed of a main control device and a number of terminal devices; a PLC device of the main control device simply needs a few of input / output ports; the main control device of a specification can meet the needs of different numbers of layers and different numbers of loading plates; each terminal device is standardizedly designed to simultaneously meet the lifting control and the transferring control of a loading plate; if the parking device needs to increase or decrease the loading plates, the terminal devices are simultaneously increased or decreased without changing the main control device; modular and standardized design is realized; and parts are highly interchangeable. The system has the advantages of convenient production, installation and maintenance, cost saving, being simple, and effectively improved reliability and safety.

Description

technical field [0001] The present invention relates to the field of lifting and traversing mechanical parking equipment (hereinafter referred to as lifting and traversing parking equipment). Standardize the terminal device, greatly reduce the wiring scale, and increase the reliability of the system. Background technique [0002] With the increase of car ownership, the problem of insufficient parking space is becoming more and more obvious. Mechanical parking equipment has been widely used. Among them, lifting and lateral parking equipment occupies more than 80% of the market due to its simple structure, low production cost and wide adaptability. . At present, the lifting and traversing parking equipment adopts an integrated control system with PLC device as the main controller. The lifting motor drive, traversing motor drive and anti-falling device drive of each vehicle-carrying board are controlled by the output signals of the PLC device respectively; Relevant signal poi...

AI Technical Summary

Problems solved by technology

At present, the lifting and traversing parking equipment adopts an integrated control system with PLC device as the main controller. The lifting motor drive, traversing motor drive and anti-falling device drive of each vehicle-carrying board are controlled by the output signals of the PLC device respectively; Relevant signal points for the in-place or over-limit of the lifting action of the vehicle-carrying board, the in-position or failure of the anti-drop device, and the in-position or over-limit of the lateral movement are respectively connected to the input ports of the PLC device, plus the emergency stop switch, human The access of signals such as car wrong-entry detection and man-machine interface devices needs to occupy more input and output ports of the PLC device, which makes the control module of the integrated control system large in scale, with many connecting cables, complex control, and high cost. It must be specially designed according to the specific situation, it is difficult to standardize production, it is difficult to install and construct, and it is inconvenient to maintain
