Abstract :
The paper mainly elaborates the design of hardware and software about intelligent monitoring system. The hardware includes DSP (That is a digital signal processor.), a variety of sensors, external circuits, the system debugging and simulating. The software includes a main program and a bus communication protocol. The system can realize functions of automatic detection and procession faults, automatic protection, and automatic display various technical indicators. These technical indicators include gas pressure, gas concentration, environment temperature, humidity, ventilator speed and motor running states. And it can achieve centralized monitoring and remote controlling, too. The experimental result shows that the intelligent monitoring system has a stable performance, flexible control and strong adaptability. The system can be widely used in coal mine ventilator surveillance occasions to promote their safety and reliability. The system can avoid gas explosion accidents caused by poor ventilation and reduce energy consumption.
