Introduction: In the MES system of the automobile manufacturing industry, according to the body-paint-final assembly process, on-site client clients of the MES system can be deployed at multiple key positions and the exits and entrances of each workshop for on-site operations. The on-site client can be deployed in a designated section in the form of an industrial computer, or operated by an operator in the form of a handheld PDA device.

In the MES system of the automobile manufacturing industry, according to the body-paint-final assembly process, on-site point clients of the MES system can be deployed at multiple key positions and the exits and entrances of each workshop for on-site operations. The on-site client can be deployed in a designated section in the form of an industrial computer, or operated by an operator in the form of a handheld PDA device.

These clients can communicate and exchange data with various modules such as data acquisition equipment, PLC equipment, production equipment, MES system production process control module, background database, workshop LED Display, and printing equipment.

Its functions are mainly to collect, input, query and display on-site data, verify data, print out and process other production information. Another important function is to update the order (finished) status as the vehicle passes the site point.

1: Data collection

This includes acquiring vehicle data from data acquisition systems (RFID, scanner guns, sensing devices).

2: Data input

Automatically or manually generate vehicle data and input, such as vehicle body number and other vehicle data that need to be generated by the MES system in the form of serial numbers.

3: Data query display

According to the vehicle identification data such as the order number, or by manual inquiry, the vehicle order details are displayed at the site.

4: Data verification

Perform data comparison and data verification according to the verification rules to ensure correct operations, correct installation of optional components, and matching of relevant data.

5: Print out

It is used to print the barcodes and forms required by each workshop, as well as the vehicle certificate and maintenance sheet required for submission.

6: Other production information processing

It is mainly the prompt alarm information when the data input fails, or the abnormality such as the verification failure, and various output data information.

After demand analysis, we found that there are commonalities and differences in the functions required by the client at each site. The opposite sex refers to the special operation requirements of a certain section, and needs to be realized by the on-site client. The commonality refers to the functions that almost all on-site point clients need to provide, such as the display of vehicle order numbers, the display of basic vehicle data, as well as the current point-of-point traffic, shift output, cumulative output, etc.

In addition, users also put forward higher stability, real-time, reliability requirements, and the client’s response capability, processing capability, communication capability, etc. must conform to the production rhythm to avoid production downtime.

After technical selection, we recommend the EclipseRCP (RichClientPlatform) platform for the design of on-site client programs. EclipseRCP is a framework for developing thick client applications based on the Eclipse project, which provides a common Eclipse workbench that allows developers to extend and construct powerful cross-platform applications.
