Ventilator non-stop switching system

Abstract

The invention discloses a ventilator non-stop switching system. The ventilator non-stop switching system comprises an upper computer module, a switch module, a central control processing module, a system control module and a ventilator module. A communication serial port of the upper computer module is connected with a communication serial port of the central control processing module through the switch module; the communication serial port of the central control processing module is connected with a communication serial port of the system control module, a signal output end of the system control module is connected with a signal input end of the ventilator module, and the communication serial port of the ventilator module is in bidirectional communication with the communication serial port of the system control module. Through fusion of the control system and a switching method, the ventilator can be switched off without stopping air, potential safety hazards such as harmful and flammable and explosive gas overrun and air stopping existing in original air stopping and switching-off are avoided, safe and efficient production is guaranteed, and good application and popularization value is achieved; and according to the scheme, economic benefits are greatly increased, and working efficiency and safety are greatly improved.

Description

technical field [0001] The invention belongs to the field of automatic control, and more specifically, the invention relates to a non-stop reversing system of a ventilator. Background technique [0002] Nowadays, ventilators are widely used for ventilation and air induction of boilers and industrial furnaces, ventilation, dust removal and cooling of shafts and tunnels. Ventilators are responsible for the important task of ensuring the safe production of equipment, and their safe operation status is the key to the safe operation of various equipment. Taking a draw-out ventilator room as an example, it is equipped with two counter-rotating axial flow fans, each fan is equipped with a vertical damper and a horizontal rotary blade damper, and the control system with the programmable logic controller as the core Realize online monitoring to achieve the purpose of non-stop wind down. There will be no wind for a short period of time (1 to 2 minutes) during the original reversing ...

AI Technical Summary

Problems solved by technology

There will be no wind for a short period of time (1 to 2 minutes) during the original reversing process. During this short period of wind suspension, there are potential safety hazards of harmful and flammable and explosive gases exceeding the limit, which is very likely to cause safety accidents and accidents. The expansion of the system will bring major safety hazards and huge economic losses
