A device that can support data collection of multiple industrial control protocols

Abstract

The invention discloses a data acquisition device in support of multiple industrial control protocols, and relates to the technique of industrial control and the technique of IT data acquisition. The technical key point provided by the invention comprises a control table, an electrical control cabinet and analog industrial infrastructures. The control table is in signal connection with the electrical control cabinet; multiple PLC controllers in support of the multiple different industrial control protocols are arranged in the electrical control cabinet; the PLC controllers are in signal connection with the analog industrial site infrastructures through a wiring panel in the electrical control cabinet; the power input ends of the PLC controllers are gathered in a master selection switch and are connected with a power supply; multiple SCADA systems and professional data collection software matching with the PLC controllers are integrated on the control table; and the control table inquires the types of the PLC controllers currently accessing the device, invokes the SCADA systems matching with the types and further builds communication channels with the PLC controllers currently accessing the device.

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.
