Industrial control system

Abstract

The invention provides an industrial control system comprising a PCI interface movement control card used for controlling electrical mechanical equipment, the PCI interface motion control card is inserted into a PCI socket of the industrial control host, and the industrial control host is in communication connection with a HMI human-computer interface based on TCP / IP or a Modbus protocol of a serial port or 485 interface. The input unit of the HMI human-computer interface is a touch input device, and the display unit is a touch screen. According to the industrial control system, the PCI interface movement control card for controlling the electrical mechanical equipment is connected with the industrial control host, the industrial control host is in communication connection with the HMI human-computer interface, the terminal user can control the mechanical equipment by using a human-computer interface with a touch screen, the industrial control system fully utilizes the strong expansibility of the industrial control host, and combines with the environment-friendly operability of the human-computer interface, the requirements of the system on field space are reduced, and the stability and convenience of the system are improved.

Description

technical field [0001] The invention relates to the technical field of equipment control systems, in particular to an industrial control system.

[0002] Existing equipment control systems are mainly divided into two categories, such as figure 1 , 2 As shown: one type is based on PLC (Programmable Logic Controller, programmable logic controller) as the core, and assists in using HMI (Human Machine Interface, human-machine interface) to control the equipment, with a human-machine interface 11, a PLC controller 12, and The electric mechanical equipment 13, the PLC controller 12 and the man-machine interface 11 are connected by communication. The screen functions of the PLC controller 12 and the man-machine interface 11 are simple and stable, and the operation is convenient. limited; the other type is centered on the motion control card 22, which generally has a PCI (Peripheral Component Interconnect standard) interface, and the motion control card 22 is inserted into the industrial control computer host (abbreviation: industrial control host 20) on the PCI socket, developers use the SDK (Software Development Kit, Software Development Kit) provided by the control card supplier to develop applications to control equipment and electric mechanical equipment 23, users and industrial control computers (referred to as: industrial computer) 21) Interaction requires a display 24, a keyboard 25 and a mouse 26

The industrial computer has powerful functions and strong expandability, but the operation needs to cooperate with the monitor, keyboard and mouse. This is limited by the space on site, which poses a problem for the equipment control system based on the industrial computer.
