First, the existing enterprise information system problems and bottlenecks

Since 2000, most domestic manufacturing enterprises have implemented the selection and construction of information systems, including enterprise resource planning (ERP). Enterprises through the implementation of information technology to build a more complete enterprise management information platform to establish a sustainable enterprise system application architecture.

1.1 existing ERP system data real-time, data accuracy and other hidden issues

ERP is a "3-stream" integration of logistics, cash flow and information flow. ERP is a real-time on-line transaction processing system. ERP data is highly shared and data is shared among different subsystems. As a result, the ERP system has high requirements on the timeliness and accuracy of the data. If the information is not timely, it will inevitably affect the system's efficiency. Inaccurate data will reduce the credibility of the system, and even misleading the production and operation of the command.

1.2 The traditional ERP system Raw data acquisition methods and access to logistics status limit the value of ERP play

After the ERP system is put into operation, the data input and information acquisition become the important and heavy work of the system. As we all know, ERP system business process is seamlessly integrated, well-designed ERP internal data flow is not repeated input of large amounts of data. However, there are two situations that the system itself can not solve. One is that the raw data enters the system and the other is the collection of the logistics status.

Raw data appears between ERP and external systems or between supply chain partners such as customers or suppliers. Typical raw data such as:

1) sales orders and customer information

2) supplier information

3) Information on material transfer and handover between independent units in the supply chain

4) non-material financial documents

5) out of storage materials and location of the identification and input

6) On-site product identification, circulation information and quality information collection and input

The above six examples of data, can not be derived from the existing data within the system. With the expansion of business scale and group business, the collection and processing of data has become more and more difficult.

Second, efficient and accurate enterprise information system should look like?

How to realize intelligent management in the process of production, delivery and logistics, how to obtain real-time dynamic data in a comprehensive, real-time and accurate manner on a unified platform so as to realize the seamless connection and sharing of information data, to create a production and marketing integration, Third-stream synchronization of integrated, intelligent operation and control system, is a good functioning of the effectiveness of enterprise information systems expectations, but also a COSCO stage of the pursuit of the goal.

Some enterprises have implemented ERP, in addition to the existing functions of ERP, an enterprise can efficiently and accurately implement the enterprise information should also have the following characteristics:

The first is the original data after identification, cleaning, input manual processing, you need to fully ensure the accuracy of data entry, to prevent errors;

Second is to ensure timely data entry;

Once again, real-time access to accurate logistics status.

In short, after solving the above bottleneck problem of ERP running process, it ensures the accuracy of data collection and real-time information input, is the effect expectation of an efficient and accurate enterprise information system operation, and is the good guarantee of the business activities of enterprises.

The arrival of the Internet of Things wave has created an era of "post-ERP" for enterprises because the Internet of Things technology can effectively solve problems such as information collection, process management and process optimization of production processes. The closed-loop application and production process of an ERP system can Trace the open-loop application of ancillary management systems for effective system integration, to achieve the goal of integrating the two cultures and establish a "smart factory."

Third, the "production process traceability support management system" and the difference between ERP systems and combinations

3.1 The production process can track the difference between secondary management systems and ERP

ERP is a "3-stream" integration of logistics, cash flow and information flow. ERP is a real-time online transaction processing system, ERP data is highly shared and data is shared among different subsystems.

Production process traceability management system uses RFID data acquisition means, you can achieve real-time data acquisition, and completely solve the production process integration of logistics and information flow to meet the lean production of real-time data acquisition accuracy, accuracy is to resolve the ERP system Increasing information identification and collection bottlenecks effective method of ERP system is an effective complement.

The traceable auxiliary management system in production process of this project is based on such a key issue as the starting point, in order to obtain real-time, accurate data and seamless, rapid data entry as the starting point for the design and development.

3.2 Production Process Traceability Auxiliary Management System How to combine ERP?

Production process traceability management system based on RFID automatic identification RFID technology, with its waterproof, moisture, oil, lightning protection, anti-electromagnetic interference, high temperature and other complex environments Excellent application capabilities, and the reading distance, long life Advantages, making intelligent enterprise applications, lean management possible.

3.3 RFID RFID introduction

In enterprise applications, Automatic Identification Data Collection (AIDC), the most promising automatic identification and data acquisition technology, is Radio Frequency Identification (RFID) technology. RFID system consists of RFID tags and readers.

An RFID tag is an integrated circuit IC chip with an antenna, where data is stored on the IC and communicated to the outside through an antenna. RFID tag size, mode of operation, accuracy, there are many types of costs are also very different, according to the needs of different businesses with different types. An RFID reader consists of one or more antennas that receive and transmit signals, and a microprocessor that decodes the received signal. Processed data is connected to the ERP system host via a conventional cable or local area wireless network WLEN. The reader can be made with the handheld terminal or it can be stationary and installed at a location such as the entrance to the factory, the door to the warehouse, the shelf or the production line.

RFID does not require visual contact between the object and the card reader. This allows for unattended identification and information storage. RFID can be read through a variety of materials other than packaging, shipping containers and metals. Read up to 100 RFID tags simultaneously.

3.4 RFID-based production process traceability management system combined with examples

Example 1: arrival receipt

ERP system also need to manually enter the variety of specifications of the incoming material to the system, and then find the purchase contract, purchase order and its corresponding, is a very cumbersome process.

Excellent ERP systems provide a range of list options to reduce part of the manual input, reducing the workload and increasing accuracy. Even so, the identification of incoming materials is still the bottleneck of the entire logistics process.
