Production line data exchange system

Abstract

The invention discloses a data exchange system for a production line, comprising: a data collection station, a PLC controller, a monitoring system, a data collection network, a switch, an Ethernet local area network, a database server, an IFIX centralized control server, and a centralized control terminal. The data collection station, The PLC controller and monitoring system are connected to the data acquisition network through industrial optical fibers, the data acquisition network is connected to the Ethernet LAN through a switch, and the database server, IFIX centralized control server and centralized control terminal are directly connected to the Ethernet LAN. The production line data exchange system provided by the present invention has a brand-new structural framework, complete networking integration capabilities, flexible application configuration modes, powerful real-time information processing capabilities, and rich display means, providing efficient application tools and reliable production process control for enterprises. Supported by information, real-time and accurate collection of production, equipment, quality, and consumption data of each on-site equipment is realized, and data services are provided for management at all levels of the enterprise.

Description

technical field [0001] The invention relates to the technical field of workshop data collection, management and control, in particular to a production line data exchange system. Background technique [0002] At present, the following problems generally exist in the production line data exchange system in the industry: [0003] 1. Lack of overall planning. When building various automated acquisition and control systems, the enterprise lacks an overall plan for the informatization of the entire workshop, which is mainly reflected in the following aspects: 1) When designing and deploying the system, there is no clear definition of its information interface, resulting in the loss of some important information , or cannot establish a smooth channel for information transmission. 2) There is a lack of standardized and unified data exchange rules.

AI Technical Summary

Problems solved by technology

When building various automated acquisition and control systems, the enterprise lacks an overall plan for the informatization of the entire workshop, which is mainly reflected in the following aspects: 1) When designing and deploying the system, there is no clear definition of its information interface, resulting in the loss of some important information , or cannot establish a smooth channel for information transmission

2) Lack of standardized and unified data exchange rules

The data interfaces of many systems are chaotic and disorderly, which creates huge troubles for subsequent integration, and also increases the workload of maintenance

3) The functions of each system expand out of order, resulting in overlapping with each other

On the one hand, a lot of repetitive work has been done, wasting manpower and material resources; on the other hand, the boundaries of the system are blurred, and the business implementation is cumbersome and complicated

4) Repeated waste of hardware construction

Each system is self-contained, and data storage, post-processing, and terminal configuration are only based on the application requirements of the system, resulting in low equipment utilization

A considerable degree of repeated construction has been done on the hardware facilities, which not only increases the investment cost of the factory, but also increases the workload and difficulty for subsequent hardware maintenance

[0004] 2. Weak security mechanism

The common problem at present is that there is a lack of reliable and effective security protection mechanisms and means between the data acquisition terminal and the original equipment, and between the data acquisition system and the management system

These industrial control terminals are expensive and spare parts are scarce. Once they are attacked and fail, the equipment will not be able to be used directly, and the losses caused to the enterprise will be immeasurable

[0005] 3. The integration efficiency is not high

Data collection in the traditional sense focuses its main functions on the realization of information collection services for the main underlying automation equipment, and its information flow is only bottom-up in most cases, resulting in information disconnection

After enterprises deploy these systems, they often can only achieve "monitoring" instead of "control"; let alone multi-system linkage, they can only do their own thing

[0006] 4. It is difficult to maintain the system in the later stage

Since there are often multiple devices of various models and specifications in the workshop of an enterprise, the most direct manifestation of the consequences is that there are quite complex and large numbers of client versions in the entire system, and the acquisition program of each device Both require separate maintenance and manual settings, making workshop maintenance personnel miserable

At the same time, the entire system lacks the continuous offline remote upgrade function for client programs. Maintenance personnel must use mobile physical storage media to replace manually set client programs one by one; and when replacing, they must exit the system and restart start, which means that normal production and data collection activities must be temporarily suspended
