Universal multifunctional industrial control device and system

Abstract

The embodiment of the invention discloses a universal multifunctional industrial control device and system. The universal multifunctional industrial control device comprises a controller, a pluralityof paths of digital quantity input interfaces, a plurality of paths of analog quantity input interfaces, a plurality of paths of digital quantity output interfaces and a communication interface, wherein the digital quantity input interfaces are connected with an operation state output port of equipment to be controlled, the analog quantity input interfaces are connected with an analog quantity output port of the equipment to be controlled, the digital quantity output interfaces are connected with a control port of an execution action part of the equipment to be controlled, and the communication interface is connected with an upper computer system of the equipment to be controlled, and is used for receiving a signal acquisition and control instruction sent by an upper computer system. The acquired running state data and / or the acquired real-time working data are sent to an upper computer system. Through the input and output of each path in the upper computer system centralized control device, different upper computer systems control different to-be-controlled devices, so that the limitation of hardware is avoided, and the control requirements of different industries can be met.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a general-purpose multifunctional industrial control device and system. Background technique [0002] Industrial control refers to industrial automation control, which is mainly realized by a combination of electronics, machinery, and software. That is industrial control, or factory automation control. It mainly refers to the use of computer technology, microelectronics technology, and electrical means to make the production and manufacturing process of the factory more automated, efficient, precise, and controllable and visible. [0003] At present, the control modes in the field of industrial control are complicated, and there are many ways to realize them. Some use PLC to realize control, and some use a single industrial control control board to realize control. [0004] The existing PLC control, built-in logic operation module, different control programs need to be written...

Problems solved by technology

[0003] At present, the control modes in the field of industrial control are complicated, and there are many ways to realize them. Some use PLC to realize control, and some use a single industrial control control board to realize control.

[0004] The existing PLC control, built-in logic operation module, different control programs need to be written in advance for different devices to be controlled, and the maintenance cost is high, and the system upgrade is inconvenient; although the use of industrial control boards to achieve control can also meet the needs of users. needs, but this mode of industrial control boards basically has a single function and this mode is heavily dependent on industrial computers. This mode is convenient for program upgrades, but this mode is costly and remote control cannot be realized
