Brief introduction of data acquisition technology for dry Yuankun and MES system

Mes system improves the production mode of traditional manufacturing, collects all the links in production, summarizes it into the total database, and analyzes the data and provides management queries. How to collect all kinds of data of workshop efficiently is an important key link to determine the success or failure of an MES project. Let's briefly discuss a few types of common data collection methods.

MES System Data acquisition

Data collection is the fundamental of MES system business, and also the basis of statistical analysis of MES system. According to different data, application scenarios, personnel ability and equipment input, the MES system needs different data collection methods and different data collection devices. According to the classification of various types of data, the use of different data collection methods.

1, the data must be entered into the data must be entered into the system must be directly obtained from the external data. The system can establish itself as the enterprise's own data collection project library through the specification basic definition function and the process data basic definition function. such as product coding, product flow, process name, process conditions objectives, etc.

2, the MES system automatically generates the data in the production process, some of the data triggered by the event can be automatically collected by the system in the process, including: The start of operation time, end time, equipment status. This kind of data, can be triggered by time, according to the original set of basic data, automatically collected by the system.

3, through the bar code collection way through the barcode collection manufacturing data is one of the most common way. The prerequisite for Barcode data collection is that the information can be expressed in an encoded manner or mapped to the corresponding relationship with the preset data through coding. Barcode method can collect data mainly include: Product lot number, material lot, processing resource numbers, transport resource number, personnel number, exception category, abnormal phenomenon, equipment status (maintenance, maintenance, failure to stop, etc.), the start of the job, the end of the job. Barcode can improve the accuracy of data entry, improve the speed of entry, and low cost. Therefore, it is advisable to classify and encode the data as much as possible, and convert it into a barcode to express it in order to facilitate field data collection.

4, the way to collect equipment data if enterprises need to control equipment, at any time to monitor the operation of equipment and facilities, can be used in the following ways: DNC network card, macro instructions, PLC acquisition method, but also some data can be collected through the barcode to achieve the desired goal, The key is to see if the need for business needs and choose a different way. Real-time and accurate production data acquisition and realization is an important foundation of MES success, the enterprise MES system construction should fully consider the characteristics of its data collection, in the process of acquisition, according to the integrity, real-time principle, a variety of collection technology comprehensive application, the principle of human-machine integration, easy to integrate application principles, use a variety of data acquisition methods , and utilize the organic combination of computer, data network language communication equipment, various technical standards and real-time historical database software to realize integrated application of production data.
