The Outdoor Fire Hydrant IoT Monitoring Terminal can monitor various status information of fire hydrants without altering their original structure. Utilizing low-power detection technology and IoT transmission technology, it transmits alarm information such as water outflow, temperature, pressure, and vibration to the cloud platform via NB, LoRa, LoRaWAN, etc., enabling centralized supervision of fire hydrants. It addresses numerous issues in current fire hydrant management, including illegal theft of firefighting water, insufficient pressure in fire pipelines, hydrant collision and tilting, and weak regulatory capacity of municipal water departments.
◆Pressure Monitoring: Monitors pipeline pressure and judges the pressure condition based on set thresholds. Under normal conditions, it uploads pipeline pressure values according to the set reporting interval; when pressure is too low or too high, it reports immediately.
◆Pipeline Temperature Monitoring: The system monitors pipeline temperature. When the temperature falls below the set value, it reports immediately. This function is particularly suitable for early warning in fire pipelines prone to freezing in northern regions.
◆ Flow Velocity Monitoring: The system monitors pipeline water flow velocity to prevent on-site faults such as leaks and water theft.
◆ Vibration & Overturning Alarm: The device body monitors in real-time for strong external impacts on the hydrant, including human vandalism such as overturning.
◆ Anti-Cover Opening Alarm: The device body is designed with an anti-cover opening function to prevent human damage and maintenance faults.
◆ Battery Level Reporting: Monitors the voltage of the power supply battery. When uploading heartbeat data and alarm information, the voltage value is included. The management platform judges the battery's working condition based on the uploaded voltage value and reminds users to replace the battery.
◆Device Positioning: The system features built-in positioning. After installation, there's no need to manually record the device location; the system automatically reports the device's latitude and longitude. This facilitates platform management of device locations and avoids human operational errors.
