基于PIC单片机的粉尘净化控制系统的设计

o solve the existence of a large number of dust in the industrial field, a structure of dust purification system program is designed. Taking PIC microcomputer as the core, by regulating the DC , the speed of the air into the system can be broadly divided into motor control, differential pressure, signal acquisition, keyboard input, and liquid crystal display. Man-interface through the keyboard can be achieved boot, shutdown, as well as the speed of the air-conditioning into the system. The realization of the system of air dust concentration in the automatic monitoring and alarm, and the LCD module dynamically displays the current value of speed and the failure of alarming information. By means of the integrated development environment-MPLAB-IDE v6.60 software, assembling program and off-circuit simulation can be made. Through the cycle the air with dust filter into the system after filtering, the export of air become standard anh healthy for human. This program has a convenient, practical, reliable, economic and other characteristics, and also has a strong promotion.
