Signal is surveyed, when turbine 31 has rotation, shows that the current in fire hydrant have flowing, and the flow velocity exceedes threshold value, if current this disappears
Anti- bolt then there are leak or steals the problem of using fire hydrant water, if flow velocity is smaller, can determine whether to deposit for the fire hydrant without fire-fighting task
In seepy question, and when flow velocity is larger, then exist and steal water or seepy question, by by two kinds of situations be characterized as leak report and
Correlation report is sent by wireless transport module, in order to which monitoring center is monitored the working status of each fire hydrant, with energy
Fire hydrant is overhauled in time, it is ensured that the safety that follow-up fire-fighting uses.
At this time it is also possible to send hydraulic pressure data, the hydraulic pressure for the fire hydrant for judging currently to go wrong in order to monitoring center is
It is no to meet fire-fighting requirement, it is ensured that be carrying out the fire fighting truck of fire-fighting task can search out recently and hydraulic pressure meet the requirements
Fire hydrant supply water.
And water consumption is calculated based on lasting flow velocity measurement data by metering module 592, so as to by with reality
Border performs the time of task compared with water consumption, judges that corresponding fire-fighting whether there is water consumption problem outside the plan, such as leak, steathily
With fire demand water problem.
Second forwarding step S3, when the flow rate of water flow in water lines exceedes scheduled duration less than the duration of threshold value,
Start wireless transport module 22 by predetermined period and send real-time hydraulic pressure data.To guarantee in time to the hydraulic pressure in fire hydrant
Be monitored, it is ensured that fire-fighting using when be capable of providing expectation hydraulic pressure.
3rd forwarding step S4, the magnetic monitoring signals characterization of magnetic reed switch output of the control module 57 in protective cover are supervised
When the changes of magnetic field amplitude that location puts place exceedes threshold value, control wireless transport module 22 sends real-time hydraulic pressure data and/or leak
Report, or start display screen work scheduled duration to show hydraulic pressure data.Personnel easy to operation are beamed back in maintenance process
The operation of data.
4th forwarding step S5, when the fluctuating range of hydraulic pressure in water lines exceedes threshold value, starts wireless transport module 22
Send real-time hydraulic pressure data.It can not meet fire-fighting requirement to prevent the hydraulic pressure in fire hydrant from becoming too low, it is ensured that fire-fighting
Bolt energy normal water supply.
