Design of Wireless Network Monitoring and Control System of Safety Parameter for Mine Air Shaft and Its Key Technologies

In view of the problems of safety parameter monitoring and data transmission of mine surface air shaft,the paper put forward a design scheme of wireless network monitoring and control system of safety parameter for mine air shaft which adopted DSP monitoring and control substation and transmitting data by wireless network,and emphatically expounded key technologies of design of monitoring and control substation,interface circuit,network selection,optimal design of wireless channel,and software design of upper and down comuputer.The system uses DSP monitoring and control substation to sample,process and display all the parameters of air shaft,and then transmit the data to the control center on ground through wireless network, which can monitor and process fault of the air shaft timely,and achieves safety production.
