With the rapid development of information technology, the era of big data has also followed. The generation of various data has driven the development of data collection systems, and gradually applied to various fields. In the manufacturing industry, the system has become an increasingly important technical means. It is an important part of quality control in the manufacturing process of the manufacturing industry. It can directly reflect the quality of the product, and can also be used as an important aspect in daily quality management. reference.

In today's manufacturing industry, data collection is still a major difficulty. Mainly reflects the following aspects:

1. At present, most enterprises still retain the traditional data collection method of manual recording. During the data collection process, there will be collection errors caused by human reasons, and their work efficiency is very low.

2. In order to adapt to the current informatization environment, some enterprises will introduce some relevant technical means, but because the enterprise has not selected a data collection system suitable for itself, and at the same time, most manufacturers' equipment source programs are not allowed to be modified, so it still cannot be achieved. The real-time and accuracy of the collection work.

3. Enterprises will purchase new equipment from time to time on the basis of old equipment, resulting in the problem of inconsistency between new and old equipment. With the innovation of control system technology, many equipment do not have network ports, most of which are DB9 and round mouth. There is no Ethernet expansion module corresponding to the product on the market, resulting in the data acquisition system not being applied well.

4. Because most of the equipment purchased by most enterprises before and after is rarely from the same manufacturer, the network segments of the equipment with network ports are not uniform and the allocation of equipment station numbers (ID) with serial ports overlaps, which makes it difficult for enterprises to informatize data Collection management.

In response to this series of problems in the manufacturing industry, the data acquisition system has exerted its unique advantages.

1. The application of the system can help enterprises to collect various types of data in the production process in real time, instead of manual operations, it also avoids certain losses caused by personnel work errors, which not only improves work efficiency, but also It can monitor all abnormal data in the production process in real time, which provides another layer of guarantee for the quality of the product.

2. The data collection system provides the production data of each device, making the production situation intuitive and clear, which is convenient for the company's management personnel to analyze the production situation, and at the same time help the enterprise optimize production and make the production plan more scientific and reasonable.

In summary, in order to implement the adjustment of the plant equipment information collection structure and make it better, and secondly, in order to improve the configurability, reconfigurability and scalability of the plant production equipment, the application of the data collection system is essential one less link.
