Option 1: Each fire pool is equipped with a passive output liquid level sensor with a liquid crystal display device, high and low water level alarm function, and wireless medium transmission (GPS/NB, etc.). A server is set up at the headquarters to receive the collection information of all liquid level sensors. , equipped with alarm function and displaying each device on the floor plan.Option 2: Each fire pool is equipped with a passive output liquid level sensor with a liquid crystal display device, which has high and low water level alarm functions, and is transmitted via wireless media (LoRa). A display device is installed in the duty room on the first floor of each factory area. The duty room is connected to the fire protection Within 500 meters of the pool, it receives information collected by the liquid level sensor in the factory area and has an alarm function.

Signal collection: The liquid level height information collection of the fire pool uses a wireless pressure transmitter and uses NB-IoT signal transmission.Software functions: Each fire pool monitoring point is displayed on the floor plan; the liquid level monitoring point information is viewed in real time; the data collection and upload interval is modified; the upper and lower limits of the fire pool liquid level alarm are modified; the software alarms when the liquid level exceeds the set upper and lower alarm limits; Historical alarm records are saved and can be queried.

Signal collection: The liquid level height information collection of the fire pool uses a wireless pressure transmitter and uses LoRa signal transmission.The liquid level information transmission method of the fire pool is as follows: software function; real-time viewing of liquid level monitoring point information; modification of data collection and upload interval; modification of the upper and lower alarm limits of the fire pool liquid level; software alarm when the liquid level exceeds the set upper and lower alarm limits ; Historical alarm records are saved and can be queried.
