In view of problems of bad coordination existed in current environment monitoring and control device of mine-used lifesaving cabin in China, the paper proposed a new type of design scheme of environment monitoring and control device of mine-used lifesaving cabin. It made a integrated design of intrinsically safe power supply, sensor, monitoring computer and communication protocol of the device to improve coordination; it used design of low power consumption and anti-interference for sensor to reduce interference of closed environment and other gas to sensor and improve stability and operability of the device.
