Door control unit for local and overall upgrading and rebuilding

Abstract

The invention relates to the field of automated control, in particular to a door control unit for local and overall upgrading and rebuilding, that is, a universal DCU. The door control unit comprisesa DCU core module, a power supply module, a driving module and an interface module; the DCU core module is used for calculating and giving an instruction to achieve control over opening or closing ofa platform door through the driving module or used for acquiring and recording real-time state information of the platform door; the power supply module is used for being connected with a power supplyto supply power to the DCU core module; the driving module is used for acquiring the instruction given by the DCU core module and driving and controlling a platform door motor to work to achieve control over opening or closing of the platform door; and the interface module is used for being connected with existing DCU interface equipment or devices of different manufactures, and then data transmission between the universal DCU and original equipment or devices is achieved. According to the door control unit for local and overall upgrading and rebuilding, DCUs of all the manufactures can be replaced, the universality is high, the product researching, developing and manufacturing period is shortened, and the door control unit can quickly respond to market changes; and negative influences onthe environment are reduced, reusing, upgrading, maintaining and treatment after product abandonment are convenient, the working efficiency is improved, and the operating cost is reduced.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a gate control unit used for partial and overall upgrading. Background technique [0002] Platform doors are a series of doors set along the edge of the subway / intercity rail platform, consisting of fixed doors, sliding doors, emergency doors and end doors. The sliding door corresponds to the train door and is used for passengers to get on and off the train. Because the subway has the characteristics of convenience, punctuality and quickness, it has gradually become one of the most important means of transportation in people's daily work and life. The platform screen door is integrated with the station platform, which perfectly solves the safety and energy consumption problems of the platform. The platform door has become the standard configuration of rail transit construction. [0003] As the core of the platform door electrical system, DCU (Door Control Unit) controls the op...

AI Technical Summary

Problems solved by technology

Many subway line platform doors, especially the core control equipment DCU, due to equipment shutdown and product upgrading, spare parts cannot be purchased or the purchase price is extremely high, and the procurement cycle is too long. While repairing in time, it is more likely to affect the daily operation of the subway, and may even endanger the safety of passengers in serious cases

[0005] At present, if the DCU is to be replaced in the domestic subway, the core equipment such as the unit controller PEDC and upper computer of the corresponding manufacturer must be replaced, which will not only lead to a long maintenance time, but also cause a great waste of resources
