Research On Dynamic Monitoring Of Pressure Balancing Ventilation

Research On Dynamic Monitoring of Pressure Balancing Ventilation Abstract The existing mine monitoring system has low anti-disturbance capability and is limited in transmitting distance. A new type single chip modem introduced in this thesis has solved that problem effectively. Be aimed at dynamic monitoring of pressure balancing ventilation, a general purpose underground sub station has been developed, which reflects real time parameters of monitored items accurately. In accordance with explosion-proof electrical apparatus regulation for mining purpose, an interface circuit for communication has been designed and softwares for communications and monitoring have also been developed. It is a first application of FSK modem in dynamic monitoring system of pressure balancing ventilation. The thesis also describes the result of on-line tests and shows that the scheme is correct and feasible.
