Problems solved by technology

[0004] Generally, when there is a problem with the MES server, if the problem cannot be solved within a short period of time, the equipment data cannot be collected, the equipment cannot be operated, and even the entire production workshop cannot be produced, and the loss is generally very serious.

Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] In the MES system, when the MES server does not fail, each data acquisition unit directly communicates with the MES server, and directly uploads the collected data to the MES server to ensure normal production. Once the MES server fails, each data acquisition unit cannot send the collected data to the MES server, which may lead to paralysis of production and cause certain economic losses to the enterprise.

[0031] The core idea of ​​the present invention is to provide a method of using distributed data collection and processing technology when the MES server fails in the offline mode in the MES system, and broadcast the production data stored in each data collection unit locally to others. All data acquisition units realize data synchron...

Abstract

The invention discloses a device and a method for acquiring off-line data of an MES (Manufacturing Execution Method) system. The method comprises the following steps that a plurality of data acquisition units of which one is a host node and the others are auxiliary nodes are set up; when faults happen to an MES server, service logic data are acquired and stored off line through each data acquisition unit, and the acquired service logic data are transmitted to other data acquisition units in a broadcast mode to be stored up; testing data are acquired and stored through each data acquisition unit when the data acquisition unit is used as a testing working station; when the server faults are eliminated, the stored service logic data of all data acquisition units are uploaded to the MES server through the data acquisition unit as the host node; the stored testing data are uploaded to the MES server through each data acquisition unit as the testing working station. Therefore, an off-line data acquisition scheme is provided for companies employing the MES system when faults happen to the MES server, the normal production is ensured, and the loss of enterprises is reduced.

Description

Technical field [0001] The invention relates to the field of offline data acquisition of a manufacturing execution system (manufacturing execution system, MES), in particular to an offline data acquisition device and method in a manufacturing execution system (MES). Background technique [0002] A three-tier enterprise integration model is proposed in the prior art, which divides the enterprise’s information system into three levels: planning layer, execution layer and control layer. The MES system is a workshop-oriented management information system located between the upper-level planning management system and the industrial control system. It provides operators with the execution and tracking information of the production plan and the current status of all resources (personnel, equipment, materials, customer needs, etc.) Information. [0003] In the field of discrete manufacturing, the real-time requirements of the MES system are relatively high. From the analysis of time facto...
