Production process information collection system for machine manufacturing workshop based on RFID

Abstract

The invention belongs to the technical field of machine manufacturing, and discloses a production process information collection system for a machine manufacturing workshop based on RFID. The system comprises an RFID collecting module, an image collecting module, a central control module, a wireless communication module, a data matching module, a data judging module, a data storage module, an alarm module, and a display module. Through the RFID collecting module and the data judging module, the system does not need to carry out the manual statistical operation of the produced workpieces, number and time, thereby greatly reducing the monitoring burden of a workshop group. Meanwhile, the image collection module collects an image comprising the workpiece state information of the machine manufacturing workshop and the state information of equipment, does not need manual statistics and table filling, guarantees the authenticity of data, greatly reduces the cost, and improves the productionmanagement efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an RFID-based production process information collection system in a mechanical manufacturing workshop. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The machinery manufacturing industry provides technical equipment for the entire national economy. Mechanical products refer to the finished products or accessories provided by machinery manufacturers to users or the market, such as automobiles, engines, machine tools, etc. are called mechanical products. According to traditional habits, any mechanical product can be rega...

AI Technical Summary

Problems solved by technology

The essence of the assembly sequence planning problem is an NP combinatorial optimization problem. There are two traditional methods of assembly sequence planning: one is based on the knowledge and experience of the assembly engineer, and this method is greatly affected by the designer's knowledge limitations and subjectivity , especially for the assembly process of complex parts, the designed assembly sequence is often not optimal, or even infeasible

The second is the graph search algorithm, but when the number of product parts is large, there will be a problem of assembly sequence combination explosion

[0008] It takes a lot of time to collect accurate actual production information for existing machinery manufacturing and processing. In particular, traditional processing equipment generally does not have data acquisition devices, which restricts the improvement of production management level of similar enterprises and leads to low production efficiency; at the same time If the production status information cannot be collected accurately and effectively, the closed-loop control of the entire production process cannot be realized, which affects the improvement of production efficiency and restricts the management level of the enterprise

[0009] Traditionally, the combination of FPGA and DSP is used to collect and process data. The data flow will consume a lot of time and the data reliability will decrease.
