Problems solved by technology

[0002] Most of the traditional sensor network data collection adopts wired transmission or single wireless transmission mode, which has a single function and poor general performance. To realize multi-functional data collection, it is necessary to gather multiple single-function devices to form a bulky operating system, which is not conducive to the system It is difficult to guarantee the reliability of the system; and the working frequency band of the wired or single wireless transmission mode is easily interfered by other radio waves, and the stability performance is poor, resulting in inaccurate data collection and transmission; The final accuracy of data collection cannot be guaranteed due to the inability to intelligently fuse data for functional data collection and transmission
