Abstract

A monitoring method for a manufacturing process comprises: receiving an input signal in which a work-in-process is input onto a conveyor; receiving a motion signal in which each of a plurality of work robots arranged around the conveyor operates; predicting the time-series position of the work-in-process on the conveyor based on the received input signal and the received motion signal; generating a movement image of the work-in-process based on the predicted time-series position of the work-in-process, and generating a process image by aligning the generated movement image with the motion images of each of the plurality of work robots generated based on the received motion signal; and outputting the generated process image to a screen. This monitoring method can monitor the process of manufacturing the work-in-process by generating a process image through the operation signal of the equipment.

Description

Method and System for Monitoring Manufacturing Process The present invention relates to a method and system for monitoring a manufacturing process capable of generating and monitoring a process video of manufacturing work-in-process through an operation signal of equipment. In a manufacturing plant, the manufacturing process is carried out by dozens to hundreds of manufacturing facilities, and the plant manager must record and manage data for each manufacturing facility to ensure that work-in-process is produced according to the target. With the recent advancement of data processing and communication technologies, so-called smart factory technology is being introduced, which manages manufacturing processes by collecting data from sensors equipped at each manufacturing facility. However, most smart factory technologies merely store process status and output the relevant information upon a manager's request, making it difficult for managers to monitor and respond to the overall process situation. In addition, with conventional technology, the load on communication volume generated during the process of collecting data from sensors equipped at each manufacturing facility could be a problem. Furthermore, additional sensing elements are required to identify the location of work-in-process on the manufacturing facility, and consequently, there was also a problem that the operation of the manufacturing facility and the location of the work-in-process had to be monitored separately. Therefore, a means is required to solve the aforementioned problem and efficiently monitor the manufacturing process.
