control system based on PLC of the mine pressure fanAbstract: Air pressor is a pressed gases to enhance gas pressure or transport gases power supply air pressor is more with its low loss, high efficiency, the advantages of strong adaptability, is widely used in industrial production the enlargement of the scale, the low efficiency of original control mode, repair rate increases and other issues are also increasingly the same time, the rapid development of electronic technology and microelectronics technology, automatic pressure control system by PLC, with high reliability and good energy saving effect, PLC automatic control system is the product of this on the understanding of social development and the demand of cases, a fan for mine pressure in Shandong project background, design and develop a kind of PLC automatic control pressure blower system, replacing the old days of manual control and distributed control, thus improve the degree of automation of the the same time the paper studies for pressor control several ways, and were summarized, at the same time, designed the fan on the overall scheme of the automatic control of pressure, hardware configuration and software and program this system, programmable controller (Siemens S7300 series) as the lower machine, better solved the problems such as automatic control。 Programmable controller。 The automatic
