In this paper, through analyzing the characteristics of the coal yard operation and dust reasons, study design pile of coal dust pollution source monitoring system automatically. Dust sensor and single-chip microcomputer technology, this system is used to test the pile of coal dust control, based on the principle of light scattering, around the single chip microcomputer as the core, the complete detector data acquisition and display circuit design. The system can realize real-time monitoring to the pile of coal dust concentration and control, to develop a complete with low cost, stable operation, the advantages of short development cycle of high performance control system, and master microcontroller system and its related software debugging tools.
