Abstract:

In order to design a monitoring and control substation for coal mine safety which has low cost, low power consumption, easy operation, strong function and high reliability, the paper proposes the design scheme of the monitoring and control substation for coal mine safety. According to the actual production safety in coal mines, the paper proposes using MCS-51 series microcontroller as the core controller and using CAN field bus as communication. Firstly, the paper gives the overall structure design of the monitoring and control substation for coal mine safety, and then introduces emphatically the design process of the analog input signal processing system, finally explain the design of the smallest single-chip system and its parts which includes keyboard, display, alarm, communication and so on. To verify the validity and the feasibility of the design scheme of the monitoring and control substation for coal mine safety, the paper using Proteus software to simulate the design content. The simulation results show that:the monitoring and control substation for coal mine safety has the alarm function when the parameter such as gas or temperature exceed the standard, and has the indication function for the motor is operating or stop, door is opening or closing. The designed monitoring and control substation for coal mine safety has a certain practical application value.
