Research of Measuring System of Performance of Mine Ventilator Based on PLC

  • 摘要: 针对现有的基于单片机的通风机性能测定系统存在编程难、不易懂,稳定性和可靠性不高等问题,介绍了一种基于PLC的矿井通风机性能测定系统的设计,详细介绍了该系统的工作原理、硬件组成和软件设计。该系统采用分布式测定方法,在完成对通风机风速、相对静压、轴温、大气压力、相电流、相电压等参数实时采集的同时,还可计算出通风机风量、功率、效率等参数;采用PLC作为测定终端系统的核心控制部件,保证了整个系统的稳定性和可靠性。

     

    Abstract: In view of problems of existing measuring system of performance of mine ventilator based on MCU such as complex programming, complicated grasping and low stability and reliability, the paper introduced a design of measuring system of performance of mine ventilator based on PLC. It introduced working principle, hardware composition and software design of the system in details. The system adopts distributed measuring method, which can complete real-time collection of parameters of wind speed, relative static pressure, axle temperature, atmospheric pressure, phase current and phase voltage of mine ventilator, meanwhile can calculate air volume, power and efficiency of mine ventilator, etc. The system uses PLC as the core control unit for testing termination, which guarantees stability and reliability of the whole system.
