Overview

Product Overview: Generally, coal mines have a wide range of depths and tunnels that are tens of kilometers long. The safety of personnel working inside them is very important, especially in case of collapse or other dangerous situations in the coal mine, which require immediate rescue. 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, is born in response to this demand. The LoRaWAN-BGPL10 personnel positioning card is an intelligent device that supports Bluetooth 4.0 and the LoRaWAN communication protocol specification. It can receive mining Bluetooth tag broadcast data and transmit the data to the main station through LoRa channel transparently. function

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.
