Embodiment Construction

[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0012] The outlet pressure of the water pump is related to the speed of the water pump and the water flow: when the water flow remains constant, the outlet pressure of the water pump is proportional to the speed of the engine, that is, the higher the speed, the greater the outlet pressure, and the lower the speed, the smaller the outlet pressure; when the water pump When the rotation speed is constant, the greater the water flow, the lower the outlet pressure, and the smaller the water flow, the greater the outlet pressure. In actual use, it is often hoped that even if the flow of water changes, the outlet pressure of the water pump is still constant, and the pressure of the outlet water can be flexibly set according to ac...

Abstract

The invention discloses a fire vehicle water pump control system which comprises an information collecting and processing module, a pump operation logic control module and a pumping pressure real-time control module, wherein the pumping pressure real-time control module carries out closed-loop control on the revolving speed of the engine according to a user key input signal and a sensor input signal transmitted from the information collecting and processing module; and therefore, when the fire vehicle injects water or the mixed liquid of water and foam in the fire hazard field, the outlet pressure of the water pump is kept constant as much as possible. According to highly-integrated visualizing information, the operation of the complete machine, data acquisition, information displaying, data analysis and data processing and controlling can be more stably, simply and visually carried out.

Description

technical field [0001] The patent of the present invention relates to the field of automatic control, especially a control system for ensuring constant pressure of the water pump of the fire truck. Background technique [0002] In recent years, frequent natural disasters and emergencies in China have aroused attention and demand for special equipment for emergency rescue and disaster relief. Emergency and disaster relief equipment is an important branch of special vehicles. This kind of equipment needs to be able to complete various rescue and disaster relief operations in an extremely complex and harsh operating environment, including emergency communication, medical rescue, fire extinguishing, disinfection, bridge and road repair, and even personnel transfer, etc. [0003] The intelligent automation control system is an indispensable condition for realizing the above-mentioned operation functions. At present, domestic fire trucks and emergency rescue equipment have not y...
