Application case of multi-parameter monitoring terminal in outdoor fire hydrant WE-NBFH02B

Outdoor fire hydrant is set in the building outside the fire water supply network water supply facilities, mainly for fire engines from the municipal water supply network or outdoor fire water supply network to take water to implement the fire, but also can be directly connected to the water belt, water gun out of water to extinguish the fire, is to fight the fire one of the important fire fighting facilities.

At present, quite a lot of fire hydrant maintenance is not enough in place, some fire hydrant there is no water, water leakage, damage, be captured and other phenomena. Fire occurs if you can not play a role, miss the best time to extinguish the fire, the consequences will be unimaginable.

Outdoor hydrant monitoring terminalsWithout changing the original hydrant structure, you can monitor the hydrant's various status information, using low-power detection technology and Internet of Things transmission technology, the water, temperature, pressure, vibration and other alarm information through wireless (e.g., the fire hydrant).NB-IOT, standard LoRaWAN, CLAA, LinkWAN) transmitted to the server, realizing the centralized supervision of fire hydrants. It solves many problems of fire hydrant management, such as illegal theft of fire water, insufficient pressure of fire pipeline, tilting of fire hydrant by collision, and weak supervisory power of municipal active water department.

Characteristics:

• Pressure collection, high and low pressure alarms
• Temperature monitoring
• anti-theft water monitoring
• Vibration, tipping alarms
• Anti-open lid alarm
• Equipment satellite positioning
• Alarm thresholds can be set

Equipment body size and appearance

Function

Pressure monitoring: Monitor the pipeline pressure, determine the pipeline pressure situation according to the set threshold, under normal circumstances, it will upload the pipeline pressure value according to the set reporting time; when the pressure value is too low or too high, it will report the pipeline pressure instantly.

Pipe temperature monitoring: The system monitors the pipe temperature and reports instantly when the temperature falls below the set value; this feature is especially suitable for early warning of fire fighting pipes that are prone to freezing in the north.

Flow rate monitoring: The system monitors the rate of water flow through the pipes to prevent leaks, water theft and other on-site failures.

Vibration, tipping alarms: The main body of the device monitors in real time the fire hydrant by strong external impact, or even tipping and other acts of vandalism.

Anti-open lid alarm: The main body of the equipment is designed with an anti-opening lid function to avoid human damage and maintenance failures.

Battery level reporting: Monitor the voltage of the power supply battery, when uploading the heartbeat data and alarm information, the voltage value follows the upload, the management platform according to the uploaded voltage value, judge the working condition of the battery, remind the household to replace the battery.

Equipment Positioning: The system has the function of equipment positioning. After the equipment installation is completed, there is no need to record the equipment location, and the system will automatically report the radius and latitude of the equipment location. It is convenient for the platform to manage the location of the equipment and avoid the mistakes of personnel operation.
