We all know that on March 30, 2020, a forest fire broke out in Xichang City, Liangshan Prefecture, Sichuan Province. The fire spread quickly and endangered the Xichang urban area. A large number of thick smoke drifted into the Xichang urban area. At the same time, local organizations and mobilize all forces to rescue disasters. Until the fire was extinguished, dozens of fire-fighting heroes gave their young lives.
The fire sounded the alarm for us! With the progress of society and the improvement of people's living standards, various types of electrical appliances have entered people's lives. Fires caused by aging lines, irregular power consumption, and carelessness have increased year by year, causing great losses to people's lives and property. How to detect and eliminate hidden dangers in time before an accident is a top priority. Facts have proved that fires caused by electrical circuits can be prevented.
When the current in the circuit is greater than the safe current, it is easy to cause a fire. Then, when the current in the circuit is greater than the safe current, it is necessary to issue an early warning and cut off the circuit in time. There are disadvantages in using the original fuse and safety switch, which obviously can no longer meet the requirements. We need a more advanced fire monitoring system. We can use the terminal plus detection / controller and connect to the data management platform through the network. The terminal monitor collects data, transmits it to the management platform for analysis, and responds accordingly. This is only one of the entry points for fire monitoring. . Then communication must first meet the three most basic requirements: massive terminal access, transmission reliability, and data security. The data traffic we currently use obviously cannot meet the requirements of mass terminals, so is there a communication technology that also meets the above requirements? The answer is yes.
DDA (Dynamic crypto space dense coverage mosquito colony rule: dynamic crypto dense ant colony) low-cost network coverage at communication distance, low power consumption design, anti-interference, communication reliability, data security, mass terminal access, robustness, Ease of use, adaptive frequency band selection and other communication technical indicators are superior to similar communication technologies. It is very suitable for fire monitoring system and has the following characteristics:
1. Low construction cost, no need to replace old equipment, no need to re-wire construction, easy equipment installation, low operation and maintenance cost
2. The reliability of data transmission is ≥99.9%, no packet loss, comparable to wired communication, but the construction cost is lower than the wired solution.
3. Possess strong anti-interference ability. In areas with dense communication, adjustable frequency anti-interference can ensure two-way real-time mass communication.
4. Certified by authoritative organizations, all indicators meet the requirements.
5. Can cooperate with professionals to formulate various energy-saving schemes to improve the utilization rate of electric energy.
