Data acquisition device in support of multiple industrial control protocols

Abstract

The invention discloses a device capable of supporting data collection of various industrial control protocols, and relates to industrial control technology and IT data collection technology. Technical points of the present invention: including a console, an electrical control cabinet and analog industrial infrastructure equipment; the console has a signal connection with the electrical control cabinet; multiple PLC controllers supporting different industrial control protocols are arranged in the electrical control cabinet Each PLC controller is signal-connected to the basic equipment of the simulated industrial site through the wiring panel in the electrical control cabinet; the power input end of each PLC controller is connected to a general selection switch and connected to the power supply; the console integrates a variety SCADA system and professional data acquisition software matching with various PLC controllers; the console inquires the PLC controller model of the current access device, calls the SCADA system matching the model and then establishes the PLC control with the current access device device communication channel.

Description

technical field [0001] The invention relates to industrial control technology, in particular to a technology supporting data collection of various industrial control protocols. Background technique [0002] The general framework of the industrial control system includes the basic equipment on site, that is, the controlled object, the electrical control cabinet and the console. The electrical control cabinet includes a wiring panel and a central control component - PLC controller (programmable logic controller). The PLC controller is connected to the basic equipment on site through the wiring panel for signal connection. The console has a signal connection with the PLC controller in the electrical control cabinet. Generally speaking, the console is an industrial control computer, on which is installed a SCADA (Supervisory Control And Data Acquisition, that is, data acquisition and monitoring control) system, which can establish a communication channel with the PLC controlle...

AI Technical Summary

Problems solved by technology

When different environmental systems need to be studied and PLC control equipment supporting different industrial control protocols is put in, the test bed cannot be updated in a timely and convenient manner, resulting in the outdated test bed device

[0004] Due to the inability to easily replace the basic equipment, it is necessary to establish a separate test bed for devices with different industrial control protocols

For the research and analysis of various industrial control protocols, the cost of this method is high and the operation is troublesome.
