小型PLC自动控制器的嵌入式设计与实现
Embedded design and implementation of small automatic controller for PLC
摘要
Abstract
In order to eliminate the disadvantages of low calibration efficiency and low test accuracy of manual debugging parameters in original production process of PLC,a small automatic controller for PLC was designed and implemented. The func-tions of AIO module,DIO module,PTA module and CPU module in PLC hardware are analyzed in detail. The automatic detec-tion scheme in module level of small automatic controller for PLC is designed on the basis of the module functions. The process of automatic detection of AIO module is analyzed emphatically. The realization process of the matrix switch and the host computer software in the automatic controller is described. The least square fitting method is used to calibrate the data in the AIO module to reduce the interference degree of the system error and improve the detection precision. The experimental results show that the detection scheme for each module of the designed automatic controller is feasible and has high test precision.关键词
