A wireless pressure gauge is an intelligent monitoring device that utilizes IoT technology for digital data transmission. It employs wireless networks and other transmission methods to send real-time collected data to the cloud, enabling remote transmission and aggregation of measurement data. This characteristic makes wireless pressure gauges irreplaceable in smart fire protection pipeline networks.

In urban areas, the typical wireless range is 1–2 kilometers, while in suburban or open areas, the range can be even greater. The network deployment topology can be designed according to specific applications and scenarios. LoRa is suitable for applications with low communication frequency and small data volumes. According to Semtech's explanation, one SX1301 gateway has 8 channels and, using the LoRaWAN protocol, can receive approximately 1.5 million data packets per day. If your application sends one packet per hour, one SX1301 gateway can handle about 62,500 terminal devices.

From the perspective of LoRa network applications, there are large networks and small networks. A small network refers to a self-contained system where users set up their own nodes, gateways, and servers. A large network refers to extensive, foundational network deployments, similar to China Mobile's communication network. From the perspective of LoRa industry practitioners, many telecom operators are also involved. As LoRa devices and networks increase, spectrum interference between them exists, which imposes requirements on the allocation and management of communication spectra. A unified coordination and management mechanism is needed, such as the management of a large network.

Application Cases

Wireless transmission fire pressure sensors can utilize various transmission methods such as GPRS, Bluetooth, WiFi, Zigbee, and LoRa. Fire detectors are critical components of intelligent building fire protection systems. They can detect signals such as smoke, high temperatures, and flames generated by fires, convert these signals into electrical signals, and transmit them to the alarm system. There are many types of fire detectors, including smoke detectors, heat detectors, and flame detectors, each with different detection sensitivities and applicable ranges.

Wireless Pressure Gauge

Fire protection pipeline networks involve a large number of devices, including deluge systems, sprinkler systems, fire pumps, and water tanks. By using real-time monitoring with wireless pressure gauges, the operational status of these devices can be comprehensively and accurately monitored, allowing for timely detection of abnormalities and providing strong data support for maintenance work.

Wireless Pressure Gauge

Wireless pressure gauges can also assess the water supply status and pressure changes in fire protection pipeline networks, enabling real-time monitoring. They facilitate timely responses to various pipeline abnormalities and support improvements and optimizations to the fire protection system. Wireless pressure gauges also support multiple protective measures to ensure stable device performance and adaptability to various complex environments and changes.

Application Cases
LoRa water pressure monitoring technology has achieved significant results in practical applications:

A logistics park in Shanghai deployed LoRaWAN pipeline pressure sensors (LORAWAN7215) with IoT gateways, enabling remote real-time monitoring of the fire protection pipeline water pressure. This addressed issues such as low efficiency and inaccuracies in traditional manual inspections, as well as difficulties in wired deployments, thereby improving the efficiency and reliability of fire protection system management.

The tunnel water fire protection system of CCCC Expressway utilized an automatic monitoring system based on LoRa and other wireless transmission technologies to achieve online monitoring and early warning of water levels in high-level tanks and water pressure in fire protection pipelines. This effectively reduced the cost and difficulty of manual inspections and resolved maintenance delays caused by remote locations and outdated traditional inspection methods.

I hope this information helps you gain a comprehensive understanding of the application of LoRa water pressure sensors in building fire protection pipeline systems. If you can share more specific project scenarios (e.g., whether it is for new buildings or retrofitting old ones, the specific height and area of the building), I may be able to provide more targeted suggestions.
