1、 Project background:

With the trend of industrial production automation more and more obvious, intelligent production machinery and equipment has replaced most of the manual labor, of course, to a certain extent, industrial production capacity is gradually improving. In order to realize the intelligent production, according to the market demand, the manufacturing execution system management is implemented through RFID technology, including the control of production execution, monitoring and management, and the management of production equipment and raw materials is realized on the basis of intelligent production and manufacturing raw material management system and machine interconnection. We will continue to achieve customized, multi variety, small batch production of products. RFID technology makes traditional production more intelligent.

RFID tag is used for raw material management. It can track and record all attributes related to each part, including production process, next process, its own color and size, and even quantity, flow direction or customized customer information. These information can be extended to the finished products after assembly. It can carry out fine production according to the needs of customers, and gradually enter the customization when the raw materials begin to flow into the production chemical production. The controller can sign and replace the original barcode technology with the RFID tag. The RFID tag can be read in a long distance and batch to avoid defects. The barcode must be visible to read, which can automatically identify and add quality data detection. It can be identified in batch, which can automatically identify the sequence and greatly improve the production level, Avoid the adverse effects of manual operation misoperation or omission. At the same time, the RFID tag is printed with chip barcode, which is compatible with the old equipment and avoids the waste of assets.

RFID technology has the following advantages in intelligent manufacturing

1. Automatic data acquisition does not need any contact, and the whole process does not need manual intervention, so it is not easy to damage;

2. It can also collect the information of objects in running state and identify multiple cards at the same time;

3. It is suitable for a series of requirements, such as bad production environment, difficult for personnel to realize, large amount of data storage, high demand for real-time data transmission, reliable and effective data transmission, etc.

Generally speaking, RFID has a great application prospect for real-time data collection in intelligent production, storage and logistics environment. It realizes the integrated management of raw materials, factory manufacturing, sales and customer demand. It can be produced flexibly according to time, demand and order, realizing real intelligent manufacturing.

All devices communicate with the acquisition server through the network, and the existing MES interfaces with the acquisition server through the database. To get all the database middleware on the data acquisition server can reduce the difficulty of the existing system conversion, clarify the work responsibility, facilitate the future maintenance and troubleshooting, improve the security of the server, reduce the openness, provide the maximum conversion and improve the production efficiency.

In order to maintain the efficiency and accuracy of production, manufacturing enterprises put forward higher requirements for the automation of production process. Without highly organized and integrated control system, it is difficult to complete such a complex task. As the development direction of future manufacturing technology, intelligent production will have a profound impact on manufacturing mode and manufacturing enterprises. As an automatic identification and acquisition technology, RFID makes production more intelligent.

RFID intelligent production adopts a novel, comprehensive and advanced production management structure, which collects data layer through Internet of things sensors, and realizes functions of material inventory, transportation, product detection, product positioning, traffic, environmental control, production process, product quality detection, finished product inventory, access control, process design and real-time adjustment through a series of software, Effective management of the whole production line to achieve the best production effect.
