product overview

Generally, the depth range of coal mines is wide, and the tunnels are tens of kilometers long. The safety protection of the workers inside is very important, especially when there is a collapse or other dangerous situation in the coal mine, rescue needs to be carried out in a timely manner, and rescue first requires geographical location information. Therefore, the personnel positioning card product used for underground work in mines, also known as "intelligent information mining lights", has emerged in response to this demand.

LoRaWAN-BGPL10The personnel positioning card is a type that supports Bluetooth4.0, supportLoRaWANIntelligent devices with communication protocol specifications. Can receive mining Bluetooth tag broadcast data and transmit it throughLoRaChannel transmits data transparently to the main station.
