QTC500 gas fire extinguishing device pressure monitoring system
The pressure monitoring system of the fire gas fire extinguishing device includes a gas cylinder pressure sensor, a multi-channel signal collector, an IoT intelligent gateway, and an IoT monitoring cloud platform. The structure is simple, the transformation difficulty is small, and the original equipment is not damaged. Among them, the all-stainless steel gas cylinder pressure sensor is packaged with Hunan Qitai metal sputtering film pressure-sensitive chip, which has high reliability and long-term stability. The sensor is installed at the pressure gauge interface of the cylinder valve, directly replacing the traditional mechanical pressure gauge, and is used for high-precision real-time monitoring of the air pressure in the cylinder.
The signal collector adopts 12-bit 8-channel input high-precision ADC digital-to-analog conversion to realize the collection and conversion of 8/16/32-channel sensor signals of the bottle group, and wireless relay through intelligent gateways such as NB-LOT Internet of Things, 4G, ZigBee, etc. Transmit to cloud server or local server, and realize remote real-time monitoring in 24 hours at the same time. The intelligent gas cylinder IoT monitoring platform can perform information management on the cylinder group, query the operating status of each cylinder pressure data in real time, report alarms in real time for abnormal cylinders, and query in time through various methods such as screen display, PC platform and handheld terminal APP. It is convenient for product maintenance and realizes low-cost and high-efficiency "smart fire protection".
The system is particularly suitable for the monitoring of fire protection equipment in key units such as urban rail transit, data center computer rooms, and telecommunication centers.
