A data acquisition module device based on opc and ua protocols

Abstract

The invention provides a data acquisition module device based on OPC and UA protocols, which relates to the technical field of data acquisition modules, and includes a housing; two rectangular protrusions are symmetrically arranged on the housing, and a group of round holes are opened on the protrusions. The bottom of the housing is provided with a set of rectangular heat sinks; a protective cover is installed on the housing, and two slidingly connected scraping blocks are symmetrically installed on the protective cover, and an antenna is installed on the housing; the inner side of the protective cover is provided with a Group of rectangular card blocks. The installation structure of the connection mechanism is improved. Through the setting of the clamping block, when the bolt is turned, the clamping block will be pushed to clamp and fix the external circuit. There are T-shaped protrusions and T-shaped grooves on the connection shell A and the connection shell B. , the T-shaped protrusion and the T-shaped groove cooperate to facilitate the installation of the connection shell A and the connection shell B. The setting of the snap-in mechanism plays the role of auxiliary fixing of the connection mechanism. When the pressing seat is pressed down, the barb will go down Move to facilitate the removal of the connecting mechanism.

Description

technical field [0001] The invention belongs to the technical field of data acquisition modules, and more specifically relates to a data acquisition module device based on OPC and UA protocols. Background technique [0002] Data acquisition is a bridge connecting the computer with the external physical world. The data acquisition module is composed of sensors, controllers and other units. The data acquisition card, data acquisition module, and data acquisition instrument are all data acquisition tools. In the OPC and UA protocols Data collection will be carried out through the data collection module, and the existing data collection module is controlled by components such as the main cabinet, display screen and PLC control cabinet. [0003] For example, the application number: CN201910059422.9 Chinese invention patent, virtual debugging system based on OPC UA industrial communication protocol, the module is mainly divided into data acquisition layer, data interaction layer, ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a data acquisition module device based on OPC and UA protocols to solve the problem that dust will adhere to the heat dissipation structure when the existing data acquisition module is used, and the dust affects the heat dissipation inside the data acquisition module. , it is cumbersome to use tools such as rags to clean up. After the external line is connected to the connecting terminal, it is impossible to intuitively judge whether the line and the connecting terminal are powered on, which affects data collection. Most of the connecting terminals are welded on the module. Yes, it is more labor-intensive during replacement and maintenance. After the external terminal is clamped to the module, the fixing effect of the connection is poor, and the problem of loosening of the terminal connection shell is prone to occur.
