Motor control method based on DCS system

Abstract

The invention relates to a motor control method and discloses a motor control method based on a DCS system. A computer sets motor operation and control parameters via network service so as to operateand control the motor. The DCS system comprises a control motor and an upper computer connected with the control motor, wherein the control motor is connected with a plurality of motors of various types, and a standard motor module is arranged in the control motor. The control method is as follows: firstly setting the equipment parameter, the operation parameter, the starting up and stopping parameter and the fault alarm parameter of each motor; calling the motor subprogram; then calling the standard motor module to perform signal processing and control on different types of motors; after finishing subprogram processing, returning to the body program which controls the motor; and meanwhile, outputting a corresponding control order, the current operation state of each motor and the fault information of the motor on the display window of the upper computer. The motor control of the invention is designed into a standard motor module, thus improving popularity.

Description

technical field [0001] The invention relates to a motor control method, in particular to a DCS system-based motor control method. Background technique [0002] For any motor control, the final control output is at most 2: start, stop, and the feedback signal of the motor is generally ready, start and stop feedback. Although there are only these limited simple signals, there are many types of motor control. In the DCS system, the motor is the most basic control unit. The quality of motor control determines the stability of the entire DCS system. [0003] In the existing public documents, the application number is 200410094969.6, the application date is November 19, 2004, the publication date is May 25, 2005, and the applicant is Panasonic Electric Industrial Co., Ltd. The Chinese invention patent application discloses a generator control A system, a generator control method, a program, and a recording medium. In the system, when the user changes the setting state of the devi...

Problems solved by technology

[0004] The present invention aims at improving the motor control existing in the prior art, which needs to compile different motor control programs for different motor types, which is not only time-consuming, but also has a low degree of human-computer interaction setting, and provides a motor control system applicable to the current DCS. For different motor types in the system, you only need to do some simple parameter settings before calling this subroutine, and you don’t need to compi
