Application Background<\/h3>\n
Fire safety is a very important part of urban public safety. High-rise, public buildings are huge in volume, complex in function, densely populated, with many sources of danger and large fire loads, which bring severe challenges to fire prevention and control. After the wireless remote pressure acquisition terminal, it can discover the water pressure status of the fire hydrant outlet in time, and signal at the first time after the water pressure is too low (high), and the platform will notify the property or relevant personnel to deal with it. Prevent fire accidents when the hydrant without water.<\/div>\n
Fire pumps are important equipment for fire fighting and rescue, and play an extremely important role in fire fighting. Fire pumps still have to play a role for some time after the fire, to complete the work of fighting the building fire. The fire pump room adopts wireless remote pressure collection terminal equipment, which does not require wiring and does not damage the original structure. The water pressure status of the water inlet and outlet of the fire pump can be found in time, and a signal will be sent out in time after the water pressure is too low (high) to notify the property owner or relevant personnel to deal with it. Guarantee that the water pump can meet the requirements of the head.<\/div>\n
After installing the wireless pressure sensing terminal, it can discover the water pressure status of fire hydrant and pump outlet in time. If the sensing terminal monitors that the water pressure is too low (high) and sends out a signal at the first time, the platform will notify the property owners or relevant personnel to deal with it.<\/div>\n

No signal in the basement is also a common situation, such as garages, underground shopping malls, subway, people usually enter these places can feel the cell phone signal instantly become weak or even no signal at all. That's because the basement is basically closed around, blocked by the house floor too much, basically can not receive the signal of the base station, want to improve the signal only to think of ways. At present, most of the basement only for the 4G signal to make up for the blind, NB-IOT \/ LORAWAN signal is very poor or almost nothing.<\/div>\n

Through the wireless Lora will transmit the sensor data to the place where there is 4G\/NB-IOT\/LORAWAN signal, and then upload the data to the cloud, solving the problem of data collection back to the blind area of NB-IOT\/LORAWAN wireless signal coverage.The Lora signal can be transmitted for 1500 meters in the open. Basement straight line transmission can penetrate 1-3 layers, and level transmission depends on the site survey. The company has a special test tool, can greatly reduce the signal instability factors. At present, there are many application cases, the data upload is stable and reliable.<\/p>\n
