Problems solved by technology

[0003] From the end of 2012 to the beginning of the year, Ford officially released two videos in a row, introducing how they use 3D printing technology to flexibly manufacture models and parts. Developing solid (clay) models is the best practice in the research and development process, but it is also very time-consuming. also expensive
[0007] But in reality, the preparation time for production change is still calculated into the production efficiency, and the production change is done manually, or the production change preparation is not prepared in advance, resulting in low production efficiency and flexible production that cannot meet the expected value.

Embodiment 1

[0047] An integrated virtual commissioning of manufacturing execution system and production line is based on the design requirements of the real production line, such as Figure 7 As shown, write a virtual PLC program; use the virtual debugging method to debug the virtual PLC program; the manufacturing execution system issues instructions to control the virtual PLC program; use the virtual PLC program to control the virtual model of the factory production line; judge the factory according to the real production line designed Does the operating result of the virtual model of the production line need to debug and rectify the manufacturing execution system until the operating result of the virtual model of the factory production line is consistent with the designed real production line;

[0048] Judging whether the control effect of the virtual PLC program is the same as that of the real PLC program, and rectifying and debugging the virtual PLC program;

[0049] According to whet...

Embodiment 2

[0139] Embodiment 2 is a variation of embodiment 1

[0140] For the production queue of the manufacturing execution system of the flexible replacement production line, the production sequence is constructed in the form of dynamic reconstruction to improve production efficiency. Such as Figure 5 as shown,

[0141] Further, the basic approach is that there are several production sequences in the control system of the entire production line, and there are different parts A, B, etc. in these production sequences.

[0142] Furthermore, when A is processed and then B is processed, we need to change the production process formula slightly. If it is artificially replaced, it may not be possible for the heavy fixtures to be humanly accessible. We need AGV to carry the fixtures and other preparations for production change.

[0143] Furthermore, if you just wait for the processing of product A to be completed, and then issue a production replacement preparation command in the manageme...

Embodiment 3

[0149] Embodiment 3 is a variation of embodiment 1

[0150] Embodiment 3 discloses a virtual commissioning method integrated with manufacturing execution system and production line, see image 3 As shown, the method includes:

[0151] Step S01: determine whether the control result of the virtual PLC program is the same as that of the real PLC program, see Figure 4 shown;

[0152] Step S02: Use the virtual PLC program written to control the operation of the virtual production line. If the production capacity, tempo and process information of the virtual production line are the same as those of the designed production line, it means that the control results of the virtual PLC program and the real PLC program are the same ;

[0153] Step S03: If the production capacity, tempo, process and other information of the virtual production line under the control of the manufacturing execution system are different from the designed production line, then gradually modify the virtual PL...

Abstract

The present invention provides a production queue construction method and system for a flexible production line manufacturing execution system, including: step M1: when different production queues appear in the management and control system of the entire production line, perform production change preparation verification; step M2: After the verification of production change preparation is successfully completed, based on the calculation algorithm of flexible production change based on dynamic reconstruction, the number of production queues prepared in advance for production change is obtained; Step M3: According to the number of production queues prepared in advance for production change, control The system issues production replacement preparation instructions in advance, calls the production replacement instructions, and completes the construction of a flexible production replacement production line; compared with ordinary production replacement methods, the present invention can save invalid waiting time between beats and improve production efficiency; improve The entire production line is flexible and highly automated.

Description

technical field [0001] The present invention relates to a manufacturing execution system for a flexible replacement production line, in particular to a production queue construction method and system for the flexible replacement production line manufacturing execution system, and more specifically to a replacement production line in the automobile manufacturing industry. Background technique [0002] Flexible manufacturing technology (FMS, Flexible manufacturing System), also known as flexible integrated manufacturing technology, is a general term for modern advanced manufacturing technology. Flexible manufacturing technology integrates automation technology, information technology and production and processing technology. It combines the isolated engineering design, manufacturing, operation and management processes in factories and enterprises in the past, with the support of computers, software and databases, to form an enterprise covering the entire enterprise. organic sy...
