The application of NB-IoT Wireless Smart Meters in the smart fire protection project at Guangzhou International Finance Center:

Fire water supply equipment is one of the important indicators for evaluating urban fire safety and fire prevention capabilities. As an essential part of public fire protection infrastructure, its proper functioning is directly related to the safety of people's lives and property.

Although most cities have established fire water supply facilities, it is often difficult to effectively monitor their actual operating conditions. In practical applications, these facilities are widely distributed, vulnerable to damage, difficult to maintain, and complicated to manage. Problems such as water leakage and unauthorized water usage may occur frequently. As a result, insufficient water pressure at the scene of a fire may prevent firefighting equipment from functioning properly, delaying the optimal time for firefighting and posing a greater threat to people's lives and property.

Therefore, in order to improve the emergency response efficiency of fire water supply systems and better protect people's safety, NB-IoT Wireless Smart Meters can be connected to an IoT-based remote fire monitoring system. By combining sensor technology with IoT communication technology, the system can remotely monitor the status of indoor fire hydrants, fire hydrant pipeline pressure, automatic sprinkler system water pressure, water levels in elevated fire water tanks and fire water reservoirs, as well as the opening and closing status of fire water supply pipeline valves.

Through a PC-based system or mobile APP, users can dynamically monitor and visualize the fire safety status of connected facilities and obtain real-time information about the operating conditions of fire water supply equipment. This helps ensure that the fire water supply system can function properly in the event of a fire, improving firefighting effectiveness and reducing potential losses.

TOPRIE's NB-IoT Wireless Smart Meter is specifically designed for monitoring fire water supply systems. The system consists of wireless pressure and temperature gauges, water leakage detectors, wireless level sensors, and water quality meters.

By installing these smart meters throughout the fire water supply system, users can monitor parameters such as pressure, liquid level, temperature, TDS (water quality), and gas concentration in real time. The collected data can be transmitted to IoT cloud platforms, including China Telecom IoT Platform, China Mobile OneNET, Huawei IoT Platform, and TLINK.

Data can be accessed through computers and mobile devices. When abnormal conditions are detected, the smart meters can immediately send alarm notifications via WeChat, SMS, voice calls, and email, allowing fire safety personnel to take appropriate action promptly.

The smart meters are powered by built-in lithium batteries and can operate for more than five years, significantly reducing the need for frequent battery replacement.

The pressure and level sensors of the NB-IoT Wireless Smart Meter feature built-in historical data storage and support historical data retransmission after network interruptions. If a network outage occurs, the smart meter automatically stores the data locally. Once the network connection is restored, the stored historical data can be transmitted to the IoT cloud platform, helping prevent data loss.

The smart meter also supports local data storage and USB data export, providing two levels of data protection for improved reliability and security.

In addition, the NB-IoT Wireless Smart Meter is designed to meet the requirements of demanding industrial environments, including moisture resistance, water resistance, explosion protection, dust resistance, and immersion resistance.

The pressure sensor offers excellent temperature and long-term stability, features a 200% FS overload pressure design, and uses a corrosion-resistant and impact-resistant 316L isolation diaphragm, allowing it to come into direct contact with most media.

Shenliang Logistics was selected as one of the Sixth Batch of National Key Leading Enterprises in Agricultural Industrialization. As a logistics and transportation base for grain, oil, bulk goods, feed, and other products, the company mainly operates grain logistics projects, aiming to leverage the advantages of the Machong grain and oil industry cluster. It integrates functions including grain terminals, transit storage, inspection and processing, distribution and bonded logistics, and market trading, forming a regional comprehensive grain logistics center.

The site covers an area of approximately 80,000 square meters, with a total building area of approximately 224,000 square meters. During large-scale production and logistics operations, fire safety is a critical issue that cannot be overlooked. To ensure safe and stable business operations, fire safety must be given high priority throughout the organization.

After TOPRIE's NB-IoT Wireless Smart Meters were installed as part of the smart fire protection project at Guangzhou International Finance Center, staff could not only view real-time data directly on the display of the wireless pressure gauges, but also remotely monitor and configure connected devices through the IoT cloud platform, WeChat Official Account, and WeChat Mini Program.

Once the monitored data exceeds a predefined threshold, the system can automatically trigger alarms through the configured notification methods, including WeChat, SMS, voice calls, and email.

This intelligent monitoring solution helps ensure that fire water supply equipment can function effectively in the event of a fire, improving firefighting and emergency response efficiency while providing an additional layer of protection for people's lives and property.
