Method and system for production monitoring

Abstract

The invention relates to a method and system for production monitoring. The method for production monitoring comprises the steps of (1) collecting the times when a product enters working procedures, operation the starting times of the working procedures, and the operation stopping times of the working procedures, (2) calculating retention times and actual operation times of the working procedures according to collected data, wherein the retention time of each working procedure is obtained by using the time when the product enters a next working procedure of the working procedure to minus the time when the product enters the working procedure, the actual operation time of each working procedure is obtained by using the operation stopping time of each working procedure to minus the operation starting time of each working procedure; (2) determining the average output time of products of a production line according to the retention times and the actual operation times of the working procedures, wherein the value of the average output time is equal to a maximum value in average retention times of the working procedures; (3) carrying out comparison between the actual operation times of the working procedures and the average output time, and adjusting configuration of the working procedures according to comparison results. The method and system for production monitoring can carry out monitoring management in a real-time, high-efficiency and accurate mode, and improve production efficiency of the production line.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a production monitoring method and system. Background technique [0002] With the diversification of customer needs and the shortening of product life cycle, the manufacturing industry needs to change the production mode of large batch automation to the production mode of high variety and small quantity and short delivery time. The production line composed of manual and automated machinery and equipment is increasing day by day. [0003] As a person with subjective initiative, the efficiency of his work is constantly changing due to the influence of many factors. On the same production line, due to the difference in the production of products and their quantities, the time required for the work of each process (also called is the residence time) is different, especially in the case of producing multiple products at the same time, it is difficult to quantitatively measure th...

Problems solved by technology

[0006] 1. The existing production management system can formulate production plans for various periods according to the order and supply of parts, but in the production process, it is often impossible to implement the plan due to various reasons, and the system cannot adjust the production plan in time;

[0007] 2. Unable to grasp the production status of each process in the production process, congestion occurs in some processes, and waiting occurs in some processes;

[0008] 3. On the production line that produces multiple products at the same time, there is no management of the production sequence of the products, let alone optimization

[0009] The patent application with the application number 200610159979.2 provides a production management system that can reduce the man-hours required from finding a problem to analyzing the cause in the production system. This method needs to know the exact information of the product with the problem, and obtain the process association through this information information, this method requires complex software and hardware systems, complex processing logic, and requires production line operators to input data, which increases their workload and reduces efficiency

[0010] It can be seen that after the production plan is formulated, the existing technology lacks real-time monitoring means in the production process, and the implementation status of the production plan and its difference from the production plan are confirmed through manual statistics.
