Research on Electrical Safety Monitoring System Based on Narrow-Band Internet of Things

Because of the national attention to fire safety, the fire protection industry has developed rapidly. As an important part of fire safety, electrical safety monitoring system has always occupied an important position in the field of safety supervision. Due to the increasing material and cultural needs of the people, the system has higher requirements for network convenience, data accuracy and transmission stability. Therefore, the traditional electrical fire monitoring equipment uses wired equipment to collect information, which has the disadvantages of easy aging, high power consumption and low sensitivity. At the same time, for Zigbee, Wi-Fi, Bluetooth and other wireless technology networking acquisition systems, there are also shortcomings such as limited network transmission data and difficult remote mass data storage. Using the Internet of Things technology, a hardware and software system for electrical safety monitoring is designed. The system mainly includes STM32 processor and corresponding modules, which are responsible for collecting the current, voltage and temperature information of the measured circuit. The data are transmitted to the cloud platform server through the NB-IoT communication module, and the data information is received in real time by the mobile phone terminal, and the detector is remotely controlled. Through the actual test, the system collects data accurately, and the cloud platform storage is convenient for remote access, which has certain application value.
