Research on Grid-based Environmental Monitoring System in Tibetan Region Based on CAT1 and RT-Thread

In order to meet the need for grid-based ecological environment management in the Tibetan region, a CATI and RT-Thread-based grid-based environmental monitoring system was developed. The STM32L476 low-power microprocessor is used to design and implement the main controller, and temperature, humidity, smoke, and flame data are collected by sensors. Through CAT-I IoT technology, it is interfaced with the IoT platform. The system employs a domestic RT-Thread embedded real-time operating system for system control and data processing at the periphery. It incorporates the high speed, low latency, and low cost characteristics of CAT-I communication technology, which simplifies and reduces the cost of the overall system structure and has significant advantages for the Tibetan region’s integrated grid environmental monitoring and governance. The system has been evaluated in the Qinghai region of Yushu. The system is stable and dependable, easy to operate and maintain, and guarantees accurate data for the comprehensive administration of the local ecological environment.
