The monitoring center 1 can monitor the corresponding inspection sign-in personnel information, time, and fire hydrant number in real time , Route, area and other information, the monitoring center 1 can remotely arm and disarm or authorize the opening according to the request or information of the on-site staff. Once a fire occurs, enter the corresponding fire address, and the electronic map of the monitoring center 1 will automatically display Information about the surrounding fire hydrants 16 and commanders can pick out the appropriate fire hydrants 16, automatically formulate the best driving route, and remotely authorize disarming in advance.
[0043] The reed switch 13 of the tamper-proof sensor in the fire hydrant 16 is normally closed. When the water outlet switch is turned off without authorization to take water or is forced to turn off the water outlet switch, valuable parts of the fire hydrant 16 and the valve in the fire hydrant 16 are stolen. The rod will rise, and the permanent magnet 4 will rise, and it will be separated from the reed switch 13 of the tamper-proof sensor. The dry reed switch 13 is in the disconnected state, and the tamper-proof sensor is pushed, and the micro-control chip will start the high-pitched buzzer. The device emits a harsh buzzing sound, and at the same time, reports the alarm to the monitoring center 1, so that it can warn or scare people who open it abnormally or thief, and prevent the situation from getting worse.
[0044] The monitoring center 1 can assign relevant processing according to the various information uploaded in real time by each fire hydrant 16, such as notifying the water company to pressurize if the water pressure is not enough, and the water flow sensor prompts water leakage to notify the patrol personnel to check and prevent water leakage again. The tamper-proof sensor and the water flow sensor jointly indicate that the water has been taken abnormally, and the manager will be notified to stop it.
