A state machine-based multi-process equipment production control device and method

Abstract

The invention discloses a production control device and method for multi-process equipment on basis of state machines. The production control device comprises an upper computer, an FPGA module connected with the upper computer and ARM modules used for controlling work of all processes, wherein each ARM module is used for controlling the work of one process; the ARM modules used for controlling the work of the processes serve as sub-state machines and are respectively connected with the FPGA module which serves as a main state machine, and the ARM modules and the FPGA module form a star topological structure; the FPGA module is connected with a motor used for shifting workpieces and a sensor used for detecting positions of the workpieces. The FPGA module is connected with the ARM modules through interactive interface modules. The corresponding ARM modules are controlled to be started according to the states of the ARM modules and the positions of the workpieces in production of the multi-process equipment. When customer requirements are changed, the sub-state machines of new processes can be conveniently modified and built. The production control device has the advantages of being high in extendibility, low in cost, high in stability and the like.

Description

Technical field [0001] The invention relates to a multi-process equipment production control device and method, in particular to a multi-process equipment production control device and method based on a state machine. Background technique [0002] In order to improve the production and processing efficiency of workpiece equipment and save production and processing costs, many workpiece equipment adopts multi-process equipment for corresponding processing in the processing and production process. In the processing of each process, it is necessary to rationalize the time and working status of each process. The control of the existing multi-process equipment usually adopts the following methods: [0003] 1. Use a high-speed industrial computer to write the host computer controller, and insert a data acquisition card through the PCI bus to realize the input and output of external signals. Utilize the high-speed computing power of the industrial computer to centrally manage and control...

However, this decentralized control idea has the disadvantage of difficulty in overall coordination

When it is necessary to increase the process, the information between each board needs to be modified, and the scalability is poor.
