Abstract: A collection module of underground personnel information based on CC2530 was designed. The module takes CC2530 as core and is carried by underground personnel, and can send environment temperature, gas concentration collected by various sensors and coding information of personnel to wireless receiver installed in roadway and then to surface monitoring computer, which can make surface manager know position, numbers and environment state of underground personnel real-timely; when it happens danger, the module can receive alarming information and emergency measures sent by surface monitoring computer and send out corresponding sound and light alarm to suggest underground personnel. The experiment result showed that the module can realize collection and transmission of position, motion state and environment parameters of underground personnel.
