Fire water monitoring system

Abstract

The invention discloses a fire water monitoring system. The fire water monitoring system comprises a centralized monitoring control host, multiple zone control auxiliary units, pressure sensors, liquid level sensors, valve control modules and fire pump control modules, wherein pressure sensors are arranged on fire hydrants and spray systems arranged on all the floors of a building, and the liquidlevel sensors, the valve control modules and the fire pump control modules are arranged in a water pool, a transfer water tank and a fire water tank on the building, the valve control modules are usedfor controlling water supplement electric valves, and the fire pump control modules are used for controlling fire pumps. Communication networking between the centralized monitoring control host and the zone control auxiliary units is achieved through a local area network. Each zone control auxiliary unit is in signal connection with multiple pressure sensors. The liquid level sensors, the valve control modules and the fire pump control modules are also in signal connection with the zone control auxiliary units. The centralized monitoring control host is connected with a visual graphical interface and data abnormity alarm device. By integrating the liquid level sensors, the valve control modules and the fire pump control modules, the water pool, the transfer water tank and the fire water tank can achieve the remote water supplement function, it can be effectively prevented that the water level is too low, and it is avoided that people have no water for putting out a fire.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a fire-fighting water monitoring system. Background technique [0002] With the rapid development of cities, there are more and more high-rise buildings and super high-rise buildings. In super high-rise buildings, the fire water system is mostly a normal high pressure system. The fire water pool is built on the roof and supplies water to the fire protection system by gravity. Abnormal water pressure often occurs, such as the failure of the pressure reducing valve, the water pressure is too high to cause water leakage, or the water pressure is too low and there is no water available when the fire is needed. Comprehensively understanding the many fire cases in China this year, we found that some fire scenes are not No water in the fire hydrant is the lack of water, which leads to the spread of the fire and causes a major fire. The reason is mainly due to the incomp...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing fire-fighting water system cannot simultaneously observe the real-time static water pressure of the fire-fighting water system, the water levels of the pool, the transfer water tank and the fire-fighting water tank, as well as the opening and closing state of the water supply electric valve and the operating state of the fire pump.
