Problems solved by technology

[0003] In the currently disclosed systems, the sensor and the upper computer basically use wireless communication. The sensor is generally an independent device and fixed at the position to be detected. Most of the sensors are powered by a built-in battery, and the working life is short. within three years

Moreover, due to the constraints of the battery power of this type of sensor, the frequency of data collection and transmission needs to be limited. Generally, the transmission time interval is more than ten minutes to tens of minutes.

In addition, data transmission adopts wireless communication, which is extremely susceptible to interference in a noisy industrial environment, resulting in a decrease in the quality and efficiency of transmitted data, which limits the application of most existing sensors
