Design of integrated communication system of mine emergency rescue command

Taking development trend of mine emergency rescue command communication system as design requirements, a design scheme of integrated communication system of mine emergency rescue command which combines with wired SHDSL, wireless WiFi and satellite communication technologies was proposed based on three-level command information transmission model. The test results show that the system meet needs of converged communication of various real-time data such as voice, video, environment monitoring parameter and personnel vital sign parameter with high transmission rate and long communication distance.
