Design and application of mine-used intrinsically-safe network access device

In view of problems of low flexibility and mobility existed in industrial Ethernet in underground difficult cable laying or welding occasions, as well as mobile data transmission, a mine-used intrinsically-safe network access device based on 2.4G-WiFi was designed. Wired Ethernet data was transmited by 2.4G-wireless transmission. The practical application results validate the access device is stable and reliable.
