Problems solved by technology

[0003] Civil air defense basements usually have less ventilation and are more humid, especially in the mildewy rainy season in southern spring, the basement is even more humid. The electrical components in the control electrical box are easily oxidized and corroded, causing the civil air defense equipment to fail to operate normally.
[0004] At the same time, the multi-line electrical components in the control electric box are relatively complicated, and the wiring installation time is long. There are many control lines for the valve and it is difficult to install far away.

Abstract

The invention discloses a chip-controlled civil air defense ventilation system. The chip-controlled civil air defense ventilation system comprises an on-duty control unit, an air inlet control unit, an air inlet unit, an air exhaust control unit and an air exhaust unit; the on-duty control unit, the air inlet control unit and the air exhaust control unit are in RS485 communication connection; andthe air inlet control unit is electrically connected with the air inlet unit, and the air exhaust control unit is electrically connected with the air exhaust unit. According to the chip-controlled civil air defense ventilation system, the RS485 communication mode is adopted for communication among the on-duty control unit, the air inlet control unit and the air exhaust control unit; the chip-controlled civil air defense system has the characteristics of being long in distance, resistant to interference, multiple in nodes and low in cost; and conversion and interlocking of ventilation modes during civil air defense engineering wartime are achieved, laying of wires and cables is reduced, the construction time is saved, and the wire material cost and the labor cost are reduced.

Description

technical field [0001] The invention relates to the field of air defense ventilation systems, in particular to a chip-controlled air defense ventilation system. Background technique [0002] The existing technology is to use the electrical components and control lines in the control electric box to automatically control the opening of the fan and the opening of the manual electric valve, so as to realize the purpose of switching and interlocking the ventilation mode in wartime. [0003] Civil air defense basements usually have less ventilation and are more humid, especially in the mildewy rainy season in southern spring, the basement is even more humid. The electrical components in the control electrical box are easily oxidized and corroded, causing the civil air defense equipment to fail to operate normally. [0004] At the same time, the electrical components in the control electric box are more complex and the wiring installation time is long. There are many control lines...
