Compression air foam mixed control system of fire truck

Abstract

The invention discloses a compression air foam mixing control system of a fire truck, which comprises an information collection and state display module, a foam mixing logical control module and a foam mixing proportion real-time control module. The foam mixing proportion real-time control module controls rotating speed of a foam mixing motor according to user panel key input signals transmitted by the information collection and state display module and current water flow and foam flow which are obtained by real-time collection through an internal digital PID controller to achieve the function of maintaining foam mixing proportion stability no matter how the water flow changes. The compression air foam mixing control system of the fire truck enables operation, information display, data collection, data analysis, data processing and data control of a whole machine to be more stable, simple, convenient and audio-visual through a highly integrated visual information system.

Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a control system that always maintains a stable foam mixing ratio no matter how the water flow on the fire truck changes. Background technique [0002] In recent years, the frequent occurrence of natural disasters and emergencies in China has caused concern and demand for special equipment for emergency rescue and disaster relief. Emergency rescue equipment is an important branch of special vehicles. This equipment needs to be able to complete various rescue and disaster relief operations under extremely complex and harsh operating environments, including emergency communications, medical rescue, fire fighting, disinfection, bridge and road repair, and even personnel transfer. [0003] Intelligent automation control system is an indispensable and necessary condition for realizing the above-mentioned operation functions. At present, domestic fire trucks and emergency rescue equipment h...
