【摘要】：本课题研究的是水泵性能参数在线监测和故障诊断系统,可降低煤矿井下的事故发生率,也可为水泵的科学管理运作提供现场参数。水泵的性能参数监测主要包括硬件设计、软件设计和仿真调试三部分,水泵故障诊断系统主要介绍转子轴向位移的检测方案。水泵性能参数监测的硬件设计主要是根据所设计的总体方案和模块功能选择出相应的硬件,主要包括数据信号采集、串口通信、最小系统、按键电路和液晶显示部分设计。根据硬件设计原理图和系统PCB图制作出相应电路板,并对电路板进行调试,以确认电路板的正确性。软件部分设计是使用Keil uvision4 C51软件开发系统,设计程序包括主程序、数据采集处理子程序、菜单子程序、显示子程序和串口通信子程序。数据采集处理子程序是采集水泵的流量、扬程、功率和转速四路信号。仿真调试是用Proteus仿真软件对单片机和外围器件进行仿真调试,为了验证系统工作的正确性和合理性需对系统进行现场试验。水泵故障诊断系统是根据确立的转子轴向位移检测参数、以单片机为控制核心建立的系统,根据系统的方案阐述其硬件组成和软件设计要点。图[46]表[15]参[41]
[Abstract]:In this paper, the on-line monitoring and fault diagnosis system of pump performance parameters is studied, which can reduce the accident rate in coal mine and provide the field parameters for the scientific management and operation of water pump. The performance parameter monitoring of water pump mainly includes three parts: hardware design, software design and simulation debugging. The detection scheme of rotor axial displacement is mainly introduced in the pump fault diagnosis system. The hardware design of pump performance parameter monitoring is mainly based on the design of the overall scheme and module function to select the corresponding hardware, including data acquisition, serial communication, minimum system, key circuit and liquid crystal display part design. According to the schematic diagram of hardware design and the PCB diagram of the system, the corresponding circuit board is made, and the circuit board is debugged to confirm the correctness of the circuit board. The software part is designed by using Keil uvision4 C51 software development system. The design program includes main program, data acquisition and processing subroutine, menu subprogram, display subprogram and serial communication subprogram. The subroutine of data acquisition and processing is to collect four signals of flow, head, power and speed of water pump. In order to verify the correctness and rationality of the system, the system needs to be tested on the spot in order to verify the correctness and rationality of the system. The water pump fault diagnosis system is based on the established axial displacement detection parameters of the rotor and the single-chip microcomputer as the control core. According to the scheme of the system, the hardware composition and the key points of software design are expounded. Figure [46] Table [15] refs [41]
