Thus, through installing first sensing head 303 and second sensing head 304 respectively in the front side and the rear side of ooff valve 600, utilize first sensing head 303 can real-time detection ooff valve 600 front side's water pressure, and utilize second sensing head 304 can real-time detection ooff valve 600 rear side's water pressure, thereby can obtain the inside ooff valve 600 both sides of water gauge main part 100 water pressure, the staff of being convenient for accurately and fast confirm whether the inside water pressure of water gauge main part 100 changes, and can confirm whether water pressure is in abnormal state fast according to the change of water pressure, improve accuracy and reliability that detect whether water pressure changed when promoting the efficiency of detecting water pressure, and in time send the warning to the staff when water pressure is in unusual, the user of being convenient for in time maintains or adjusts the fire water gauge.
As shown in fig. 8, optionally, after acquiring the pressure information in the fire-fighting pipeline and monitoring the change value of the pressure, the method further includes: SO3 judges the state of the fire-fighting pipeline according to the pressure information, and sends out warning information under the condition that the pressure information is abnormal. Thus, when the fire-fighting pipeline is in a normal use state, the pressure in the fire-fighting pipeline is obtained by the pressure sensing assembly 302, and the pressure in the fire-fighting pipeline is continuously monitored in real time through the pressure sensing assembly 302 in the use process, when the change of the pressure in the fire-fighting pipeline is detected, the use state of the fire-fighting pipeline is observed at the moment, when the fire-fighting pipeline cannot be continuously used normally, the abnormal pressure is indicated, and warning information is sent to a worker, so that the worker is reminded of overhauling a fire-fighting water meter or the fire-fighting pipeline, the situation that the fire-fighting pipeline is used under the condition that the pressure in the fire-fighting pipeline is abnormal can be avoided, the safety when the fire-fighting pipeline is used is improved, and the fire-fighting pipeline can be better used under the emergency condition.

It can be appreciated that: the geographical position information of the fire fighting water meter can be determined through the positioning component 700, the positioning component 700 is GPS positioning, and the GPS positioning is internally provided with a terminal of a GPS module and a mobile communication module, so that positioning data obtained by the GPS module are transmitted to a server on the Internet through the mobile communication module, and the position of the terminal can be inquired on a computer or a mobile phone, and a worker can quickly and accurately determine the specific position of the fire fighting water meter with abnormality.
Optionally, the pressure information presence abnormality includes: the pressure in the fire line is lower than the normal pressure value. Therefore, under the condition that the pressure in the fire-fighting pipeline is lower than the normal pressure value, the pressure in the fire-fighting pipeline is in a smaller state, at the moment, the fire-fighting pipeline is likely to have a water leakage phenomenon or other water pipes are connected into the fire-fighting pipeline, so that the pressure in the fire-fighting pipeline is reduced, at the moment, warning information is sent to a worker, the worker can be quickly reminded that the fire-fighting pipeline is in an abnormal state, and the worker can overhaul the fire-fighting pipeline in time.
Optionally, calculating the water flow rate through the fire conduit based on the pressure variation value comprises: the opening degree of the on-off valve 600 is calculated from the pressure difference between the front and rear of the on-off valve 600, and the water flow rate is calculated from the opening degree of the on-off valve 600 and the pressure value of the rear side of the on-off valve 600. In this way, since the opening degree of the switching valve 600 is related to the pressure difference before and after the switching valve 600, and the larger the pressure difference before and after the switching valve 600 is, the smaller the opening degree of the switching valve 600 is, and the larger the opening degree of the switching valve 600 is, the opening degree of the switching valve 600 can be accurately calculated by using the pressure difference before and after the switching valve 600, and the flow rate of water is related to the opening degree of the valve, and the pressure difference before and after the valve, so that the water flow rate of the fire-fighting pipeline can be accurately calculated according to the opening degree of the switching valve 600 and the pressure value at the rear side of the switching valve 600, the metering error is reduced, the metering result is more reliable, and the metering precision and the reliability of the metering result are improved.
Alternatively, the relationship between the pressure difference before and after the on-off valve 600 and the water flow is positive, namely: q= Δp×k, where Q is water flow, Δp is a pressure difference between the front and rear of the switching valve 600, K is a fixed coefficient, and K is related to a flow area of the pipeline, and under a condition that the flow area of the pipeline is constant, the fixed coefficient k=0.62 is taken. In this way, the water flow rate can be accurately calculated by using the positive correlation between the pressure difference and the water flow rate, and in addition, when calculating the water flow rate, the flow resistance of the pipeline, the fluid density and the like are not considered, for example: the pressure of the front side of the switch valve 600 is determined to be 5MPa by the first sensing head 303, the pressure of the rear side of the switch valve 600 is determined to be 4.2MPa by the second sensing head 304, and then the pressure difference Δp=5 MPa-4.2 mpa=0.8 MPa before and after the switch valve 600, and at this time, the water flow q=0.8 mpa×0.62=0.496; when the pressure difference Δp is 0.9, 1, 1.3 in order, then the water flow rate Q is 0.558, 0.62, and 0.806 in order.
It can be appreciated that: the pressure difference is often determined by a fluid channel formed by the opening degree of the valve, and the smaller the opening degree of the on-off valve 600 is, the larger the pressure difference between the front side and the rear side of the on-off valve 600 is; the larger the opening of the switching valve 600 is, the smaller the pressure difference between the front side and the rear side of the switching valve 600 is, so that the magnitude of the flow rate of water is related to not only the opening of the valve but also the pressure difference between the front side and the rear side of the valve, and therefore, when the opening of the valve is changed, not only the flow rate of water is changed, but also the pressure difference between the front side and the rear side of the valve is changed, and in addition, if the switching valve 600 is in the all-open state, the pressure on the front side of the switching valve 600 is higher than the pressure on the rear side of the switching valve 600, which means that the fire pipe has a water leakage phenomenon or other water pipes are connected into the fire pipe, and the pressure in the fire pipe is always at a smaller value, and at this time, the fire pipe needs to be overhauled.
