The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a water consumption state detection system for a fire hydrant provided in an embodiment of the present invention, and as shown in fig. 1, the water consumption state detection system for a fire hydrant includes a fire hydrant, a wireless remote acquisition device, and a server, a corresponding electronic tag is provided on the fire hydrant, a water inlet end of a valve flap of the fire hydrant is connected to a well chamber through a water inlet pipe, a water outlet end of the valve flap of the fire hydrant is connected to a water outlet pipe, and electronic pressure gauges are respectively installed at the water inlet end and the water outlet end of the valve flap of the fire hydrant.
It is understood that a hydrant is a fixed fire-fighting device and its main functions are to control combustibles, isolate comburents, eliminate ignition sources, etc. If the fire hydrant is in the water use state, a danger is indicated, that is, a fire can be found through the water use state of the fire hydrant.
Based on this, the embodiment of the invention provides a system for detecting the water condition of the fire hydrant, wherein the fire hydrant is provided with a corresponding electronic tag, and the fire hydrant can be identified through the electronic tag so as to track the fire occurrence place.
An electronic pressure gauge is respectively installed at the water inlet end and the water outlet end of the valve clack of the fire hydrant and is respectively used for detecting the water pressure of the water inlet end and the water pressure of the water outlet end and recording the time for detecting the water pressure.
The two electronic pressure gauges upload the time for detecting the water pressure at the water inlet end, the time for detecting the water pressure at the water outlet end and the water pressure at the water outlet end to a server through a wireless remote acquisition device; and the server is used for judging the water using state and the water using duration of the fire hydrant according to the time for detecting the water pressure of the water inlet end, the time for detecting the water pressure of the water outlet end and the water pressure of the water outlet end.
The electronic pressure gauges are respectively arranged at the water inlet end and the water outlet end of the valve flap of the fire hydrant and are respectively used for detecting the water pressure at the water inlet end and the water pressure at the water outlet end of the valve flap of the fire hydrant; and judging the water using state and the water using duration of the fire hydrant according to the time for detecting the water pressure of the water inlet end, the time for detecting the water pressure of the water outlet end and the water pressure of the water outlet end. According to the pressure change of the water inlet pipeline and the pressure change of the water outlet pipeline, the water using state of the fire hydrant is judged, so that the fire disaster condition can be further known, and the fire hydrant is simple and convenient.
In a possible embodiment, the server is configured to determine the water usage status and the water usage duration of the fire hydrant according to the time of detecting the water pressure of the water inlet end, the time of detecting the water pressure of the water outlet end, and includes: when the water pressure at the water inlet end is changed from 0 to be larger than 0 and the water pressure at the water outlet end is reduced to exceed a preset proportional value within a preset time period, judging that the valve clack of the fire hydrant is opened and the fire hydrant is in a water using state; and determining the duration of the fire hydrant in the water using state according to the time for detecting the water pressure of the water inlet end and the time for detecting the water pressure of the water outlet end. When the water pressure at the water inlet end is changed from more than 0 to 0 and the water pressure at the water outlet end rises over a preset proportion value in a preset time period, the valve clack of the fire hydrant is judged to be closed, and the fire hydrant is in an unused state.
