This article mainly explains "what are the methods of MES system data collection". The explanation content in this article is simple and clear, and it is easy to learn and understand. Please follow the ideas of Xiaobian to study and learn "what are the methods of MES system data collection" together.
1. Data that must be entered
Data that must be entered refers to data that the system must obtain directly from outside. The system can completely establish its own data collection project library through the specification basic definition function and the process data basic definition function.
For example, product code, product flow, process name, process condition target, etc.
2. Data automatically generated by the system
Some data triggered by events in the production process can be automatically collected by the system during the process, mainly including: the start time of the process operation, the end time, the equipment status, etc. This kind of data can be triggered by time and automatically collected by the system according to the original set of basic data.
3. By means of barcode collection
One of the most common ways to collect manufacturing data is through bar codes. The premise of barcode data collection is that information can be expressed in a coded way or a corresponding relationship with preset data can be established by coding.
The data collected by barcode mode mainly include: product batch number, material batch number, processing resource number, transportation resource number, personnel number, abnormal category, abnormal phenomenon, equipment status (repair, maintenance, fault shutdown, etc.), operation start, operation end, etc.
Barcode can improve the accuracy of data entry, improve the speed of entry, and the cost is low. Therefore, it is recommended to classify the data as much as possible and then encode it, and convert it into barcode expression to facilitate field data collection.
4. Sensor data acquisition
Some industries have strict requirements for temperature, pressure, humidity, etc., and their related data sources can be increased by various sensors. The acquisition mode is mainly composed of temperature sensor, pressure sensor, wireless data acquisition card and PC.
5. RFID data collection
In the automotive industry, automated logistics tracking is a prerequisite for smooth production, as production is entirely to order and there are hardly two identical ordered cars. For each production process, the car must be clearly identified to avoid problems such as incorrect installation of air conditioners and different paint colors. RFID technology is applied to the assembly line to produce customized cars in as large quantities as possible. Users can choose the colors and engine models they need from tens of thousands of internal and external options, so that hundreds of models of cars have to be assembled on the assembly line. RFID system is equipped on the assembly line, using reusable electronic tags, which can carry all the information required by the car in detail, and RFID readers are available at each working point, which can ensure that the car can complete the assembly task without error at each assembly line position.
Real-time, accurate production data acquisition and realization is an important basis for the success of MES manufacturing execution system. The characteristics of data acquisition should be fully considered in the construction of MES manufacturing execution system software. In the acquisition process, according to the principles of integrity, real-time, comprehensive application of multiple acquisition technologies, man-machine integration, and easy integration, various data acquisition methods should be used, and computer, data network, communication equipment, The organic combination of various technical standards and real-time historical database software realizes the integrated application of production data.
In short, MES manufacturing execution system is characterized by the ability to collect all kinds of information and data in the production process in real time, and then collect them into the database for data analysis and management query. How to collect all kinds of workshop data efficiently is an important key link to determine the success or failure of an MES manufacturing execution system software project.
Thank you for your reading. The above is the content of "What are the ways of MES system data collection?" After studying this article, I believe everyone has a deeper understanding of the ways of MES system data collection. The specific use situation still needs to be verified by practice. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
