Design of Mine-used M2M Terminal System Based on WCDMA

In order to transfer information of underground personnels, devices and environment to information center of coal mine through existing underground communication network, the paper put forward a design scheme of mine-used M2M terminal system based on WCDMA, and introduced hardware and software design of the system in details. The system realizes functions of information acquisition of underground targets, human-computer interaction operation and data communication, and realizes Internet of Things of things and things, things and people, and things and network by transmitting data through WCDMA.
