Problems solved by technology

[0002] At present, wireless data communication networks based on technologies such as Bluetooth, WIFI, and Zigbee play an extremely important role in industrial and agricultural production, commercial activities, and daily life, and also effectively overcome the data communication problems existing in traditional online data communication networks Network construction is difficult, construction and maintenance costs are high, system expansion ability is poor, the communication network is easily interrupted due to cable failure, poor failure resistance and low efficiency of troubleshooting operations, etc. The data wireless data communication devices used to build a wireless communication network are usually traditional wireless data transceiver base stations, wireless routers and other equipment during operation. Although they can meet the needs of use, on the one hand, there are insufficient sealing performance and safety protection performance of the equipment. It is very easy to cause equipment failure due to dust, liquid droplets and other pollutants in the external environment, and it is also very easy to cause flammable gas, dust, etc. Combustion or even explosion has seriously affected the safety and stability of communication operations and normal production operations. On the other hand, due to the interference of complex electromagnetic environments and terrain, especially in harsh working environments such as mines, it is very easy to cause wireless communication problems. The signal is due to electromagnetic interference, which leads to low data communication efficiency, serious data loss, serious clutter pollution in communication wireless signals, and serious communication signal attenuation, which seriously affects the reliability and stability of communication signal transmission. The distance of wireless communication operation is shortened. Therefore, in view of this problem, it is urgent to develop a wireless data communication device that can effectively overcome the complex electromagnetic pollution environment and has good safety protection capabilities to meet the needs of actual use.
