Embodiment Construction
[0042] Please refer to figure 1 , Is a schematic flow chart of an embodiment of a method for alarming abnormal water pressure in a fire water supply pipe network provided by the present invention. It includes:
[0043] Step S11: Collect the water pressure value of the monitored part in the fire water supply pipe network.
[0044] Among them, step S11 mainly realizes the collection of water pressure values through equipment such as water pressure sensors. The monitored part usually refers to the fire hydrant in the fire water supply pipe network. Specifically, the water pressure sensor can be installed in the lower part of the fire hydrant and the fire pipe connection. In addition, step S11 can collect water pressure values in real time or at regular intervals. Preferably, since the water pressure abnormal alarm does not have high requirements for real-time performance, you can choose to collect water pressure values at regular intervals, for example: every 1 minute or 3 minu...

The invention provides a method and a system for warning abnormal water pressure of a fire-fighting water supply pipe network. The method includes: a water pressure value at the monitored position in the fire-fighting water supply pipe network is acquired; when the acquired water pressure value is less than a standard water pressure value, a warning level at the water pressure dimension is determined according to level of the acquired water pressure value less than the standard water pressure value, and a warning level at the time dimension is determined according to duration time of the water pressure value at the monitored position less than the standard water pressure value continuously; a final warning level is determined according to the determined warning level at the water pressure dimension and the determined warning level at the time dimension, and warning is performed according to a warning strategy corresponding to the determined final warning level. The method and the system for warning the abnormal water pressure of the fire-fighting water supply pipe network can achieve multi-dimensional and multi-level warning modes. Compared with an existing warning mode, the method and the system for warning the abnormal water pressure of the fire-fighting water supply pipe network can reflect abnormal conditions of the water pressure and have good warning effect.
Description
Technical field [0001] The invention relates to the technical field of fire safety, and in particular to a method and system for alarming abnormal water pressure in a fire water supply pipe network. Background technique [0002] Fire water supply pipe network includes: city fire water supply pipe network and building fire water supply pipe network, which is an important part of urban infrastructure and building fire safety. Especially in the long-term use of high-rise buildings, due to the lack of fire safety awareness of property personnel, they neglected the management and maintenance of fire alarm systems, fire water supply pipe networks, fire hydrants and other fire fighting facilities, resulting in long-term failure or paralysis of some fire fighting facilities. It cannot be used normally. When a fire occurs, the fire fighting system cannot be linked in time and cannot play its due role. For this reason, some existing schemes for monitoring and alarming the water pressure o...
