Embodiment Construction

[0050] In the existing industrial control system, it usually consists of multiple links, with figure 1 The servo control system shown is taken as an example, including the host controller located in the host computer, the servo controller communicated with the host controller, and the servo motor (Servo Motor) connected to the servo controller, wherein the host controller and Serial communication technology can be used between the servo controllers, and between the servo controller and the servo motor, for example, the upper controller and the servo controller are connected by RS232C serial interface and communicate based on the serial communication protocol. A servo motor is a device that controls the operation of mechanical equipment in a servo control system. The servo motor can control the speed and the precision of the position control is very accurate, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo moto...

Abstract

The invention relates to the computer control technology, and particularly relates to the device operation control technology in an industrial control system, wherein the accuracy of the industrial system is ensured and the control of the running time is further realized. According to the embodiments of the invention, a method and a device for preventing the replacement of original equipment in the industrial control system are provided. The configured verification information of controlled equipment is pre-stored in control equipment. Meanwhile, before the operation of the controlled equipment each time, whether the controlled equipment is replaced or not is verified according to the verification information. Therefore, the control accuracy of the system is ensured. Furthermore, the running time of the controlled equipment or the industrial control system of the controlled equipment is monitored.

Description

technical field [0001] The invention relates to computer control technology, in particular to a device operation control technology in an industrial control system realized by serial communication technology. Background technique [0002] With the development of computer networking and microcomputer graded distributed application systems, the function of communication is becoming more and more important. Communication refers to the information transmission between the computer and the outside world, including the transmission between computers, as well as the transmission between computers and external devices, such as terminals, printers, and disks. In the field of communication, according to the number of data bits transmitted each time in data communication, the communication methods can be divided into: parallel communication and serial communication (Serial Communication). [0003] Serial communication refers to the serial transmission of data between the computer host...
