Problems solved by technology

[0004] 1. The ZigBee protocol stack itself has certain disadvantages. For example, if the network coordinator cannot work normally due to power failure or other reasons and needs to be restarted, all sensor nodes need to be restarted at this time, otherwise the sensor nodes will try to connect to other networks.
Also, if it is necessary to form a more complex tree or grid network, the power consumption will inevitably increase, and the network link will be relatively unreliable
[0005] 2. Since the frequency band used by ZigBee in China is 2.4GHz, compared with the frequency band below 1GHz, this frequency band has shorter transmission distance, greater attenuation in the transmission process, weak signal penetration and diffraction capabilities, and greater negative effects of multi-path propagation. In addition, the frequency band is already very crowded at present, and there are still many different standards such as WIFI and Bluetooth, and the mutual interference is relatively large.
