Problems solved by technology

[0002] At present, the development of various special equipment requires a large number of tests to verify its functionality and reliability, and to effectively improve product quality. However, it is difficult to obtain equipment parameters through wired methods during the test process. At the same time, there is strong electromagnetic interference in the test environment. Wireless communication is carried out through traditional Bluetooth, WIFI, LORA, Zigbee, etc. At the same time, in order to obtain higher acquisition accuracy and sampling frequency, a higher transmission bit rate is required. Except for WIFI, the other bit rates of traditional wireless transmission are very low. However, WIFI communication is less secure and susceptible to interference, and the peripheral design components are complex

In addition, in some complex application environments, communication devices cannot be powered by wired means, and wireless power supply or batteries are required.

Batteries have natural use defects, and the environmental requirements are relatively high. Temperature and pressure will affect their life and use.

Therefore, the communication modules in the prior art cannot reliably acquire signals in environments such as strong electromagnetic interference, high rotation, and high temperature.
