General assembly workshop repair area exhaust fan control management system and method

Abstract

The invention relates to a general assembly workshop repair area exhaust fan control management system and method. The invention discloses a control and management system for pumping and exhausting fans in a repair area of a general assembly workshop. The control and management system comprises a main switch control device, a plurality of opening control devices and a plurality of fan switch controllers; the main switch control device comprises a main switch power supply, a PLC controller and a switch. The main switch power supply is used for supplying power to the PLC and the switch, and thePLC is used for transmitting a control signal to the opening control device through the switch; the opening control device comprises an opening power supply, an interface module, a power module and aplurality of output modules; and the opening power supply is used for supplying power to the interface module and the power module. According to the invention, all the fan switch controllers are controlled by the main switch control device through the PLC and the opening control device, so the control management of the suction and exhaust fans in the general assembly workshop is realized, and manual intervention is not needed.

Description

technical field [0001] The invention relates to the field of control systems, in particular to a system and method for controlling and managing exhaust fans in the rework area of ​​an assembly workshop. Background technique [0002] At present, the general assembly rework area of ​​the automobile industry is the initial start-up detection area of ​​the vehicle. Vehicle exhaust emissions are collected and processed by exhaust fan devices. At present, separate manual start-up exhaust fans are set up. Generally, the rework area consists of about 30 exhaust fans (industry plan 1) ), the status quo requires employees to manually turn on / off one by one a total of 10 times a day (work, morning break, lunch break, off work, afternoon break), resulting in more indirect fans running every day, resulting in energy waste throughout the year; the rework area corresponds to turning on the fans of vehicles reworked on weekends Overuse, running time is out of control, resulting in energy wa...

Problems solved by technology

[0002] At present, the general assembly rework area of ​​the automobile industry is the initial start-up detection area of ​​the vehicle. Vehicle exhaust emissions are collected and processed by exhaust fan devices. At present, separate manual start-up exhaust fans are set up. Generally, the rework area consists of about 30 exhaust fans (industry plan 1) ), the status quo requires employees to manually turn on / off one by one a total of 10 times a day (work, morning break, lunch break, off work, afternoon break), resulting in more indirect fans running every day, resulting in energy waste throughout the year; the rework area corresponds to turning on the fans of vehicles reworked on weekends Excessive use, running time is out of control, resulting in energy waste

[0003] During the construction of the vehicle production workshop, the exhaust fan was not considered to be managed according to automatic operation control, and the pipeline was operated through manual intervention by employees more than 10 times a day. The effect was not ideal, and there was insufficient precision and energy Waste, specifically the following disadvantages: 1) Manually start and stop multiple typhoon cabinets one by one, resulting in a waste of man-hours; 2) There is no responsibility to control the start and stop of the fan during the weekend when the vehicle is being repaired, and anyone can open the wind cabinet at will; 3) Changes in production scheduling, production time and non-production time cannot be confirmed, and can only be managed through personnel intervention; the above problems are mainly summarized into three points: there is a large and obvious waste of energy, and its operation is time-consuming and laborious, and the effect is not good

However, it still cannot effectively solve the above problems

[0005] Therefore, there are deficiencies in the existing exhaust fan control system in the rework area of ​​the assembly workshop, which needs to be improved and improved
