Smart Fire Fighting Project Solution in ShenZhen Shenliang Logistics

      NB-IOT wireless intelligent instrument used in ShenZhen Shenliang Logistics Smart Fire Fighting Project:

      Fire water supply equipment is one of the important indicators to measure the urban fire safety environment quality and fire control ability. As an important part of public fire protection facilities, whether it can play its role is directly related to the safety of people's lives and property. At present, most cities have built firefighting water equipment, but they cannot effectively monitor the actual use of firefighting water supply equipment. In actual applications, there are characteristics such as scattered installation, easy destruction, difficult maintenance, and complicated management. Phenomenon such as water use leads to insufficient water supply pressure at the fire site, so that the fire fighting equipment cannot play its role in extinguishing the fire, delaying the best time to extinguish the fire, and thus threatening people's lives and property safety.

      Therefore, in order to improve the efficiency of firefighting and rescue of firefighting water supply equipment and protect people's lives. The NB-IOT wireless intelligent instrument is used to connect the IoT fire remote monitoring system, which can be combined with sensor technology and IoT communication technology to remotely monitor the indoor hydrant status, hydrant pipe pressure, automatic sprinkler system water pressure, and high-level fire water tank and the fire tank water level, fire water supply pipeline valve opening and closing status, etc. And through the PC computer, mobile phone APP system, dynamic monitoring, three-dimensional displays the fire safety status of the networked unit. Real-time monitoring of the use of fire water supply equipment to ensure that the fire water supply equipment can play an important role when sending fire, which can ensure life safety and reduce the loss caused by fire.

      Shenliang Logistics was selected as the "Sixth Batch of National Key Leading Enterprise Units in Agricultural Industrialization" as a storage and transportation base for grain, oil, bulk and feed, mainly for the construction and operation of deep grain grain logistics node projects, giving full play to the grain and oil industry cluster in Mayong Effect, build a comprehensive grain circulation service provider integrating grain and oil terminals, transit reserves, testing and processing, distribution bonded, market transactions and other functions, and form a regional grain logistics center. It covers an area of 80,000 square meters and a building area of 224,000 square meters. During the large-scale production process of the enterprise, the fire safety problem has become an important issue that cannot be ignored. In order to ensure the safety of production and operation of the enterprise, all personnel of the enterprise must pay attention to the work of fire safety.

NB-IOT wireless intelligent instrument is specially designed for monitoring fire water system. NB-IOT wireless intelligent instrument is composed of wireless pressure, temperature gauge, water immersion, wireless liquid level and water quality gauge. The instrument is installed in each fire water system, which can monitor the pressure, liquid level, temperature, TDS (water quality), gas and other data in real time. Data can be transferred to the IoT cloud platform (currently supports several major IoT platforms such as telecommunication platforms, mobile onenet platforms, Huawei platforms, TLINK platforms), and data can be viewed on computers and mobile phones. When the data monitoring is abnormal, the intelligent instrument will immediately send out alarm information through WeChat, SMS, phone, mailbox, etc., so that firefighters can make specific firefighting response. In addition, the smart meter has a built-in lithium battery for power supply and can work for more than five years, which solves the trouble and worry of frequently changing the battery.

      The pressure and liquid level sensors of NB-IOT wireless smart meters have their own historical data storage function and support historical data breakpoint continuous transfer function. If the network interruption occurs under special circumstances, the smart meter will Transmit historical data to the IoT cloud platform as soon as possible to avoid data loss and other phenomena. The smart meter itself also comes with saved data and can be exported with USB at any time. Data is saved on both sides, which is reliable and safe.

      In addition, the NB-IOT wireless intelligent instrument can meet the requirements of harsh working conditions such as moisture resistance, waterproof, explosion-proof, dust-proof, and anti-soaking. The pressure sensor has high temperature stability and time stability, and it has a 200% FS overload pressure design and corrosion resistance and impact resistance 316L isolation diaphragm, which can be in direct contact with most media.

      After installing Topray NB-IOT wireless smart instrument in Dongguan Shenliang Logistics, the staff can not only see the data directly on the display interface of the wireless pressure gauge, but also through the Internet of Things cloud platform or WeChat public account, WeChat applet remotely monitor and configure the binding device. Once the data exceeds its limited range, it can be alarmed by the set method. The alarm methods include WeChat, SMS, voice, and mailbox. This ensures that the firefighting water supply equipment can play its role when a fire occurs, which not only improves the firefighting and rescue efficiency of the firefighting water supply equipment, but also further guarantees the safety of people.
