Embodiment 1

[0040] Combination below Figure 1 ~ Figure 3 The method for monitoring abnormal data of the present invention is specifically described, figure 1 It is a schematic diagram of the structure of the production execution system, including:

[0041] The data collection module 10 is used to collect the input data and output data on each station on the production line, wherein, the structural schematic diagram of the production line refers to figure 2As shown in , the production line includes several stations, such as station 1, station 2, station 3..., the data collection module 10 automatically collects some input data and output data on each station on the production line, the input The data includes raw material attributes and station parameters on each station. Raw material attributes include raw material suppliers, batches, production dates and their characteristics. It is understandable that each station can have one or more raw materials. This In the embodiment, take stat...

Embodiment 2

[0058] The difference between this embodiment and the first embodiment is that at a certain moment, more than two input data among several input data are changed at the same time, and they are treated as a whole, for example, the data of raw material A in station 1 is changed at the same time. Batch and press speed. Before the change and after the change, the significance of the output data on each workstation is calculated within a plurality of time widths. The method for calculating the significance is the same as that in Embodiment 1, and will not be repeated here.

[0059] According to the calculated significance results, determine whether the impact of the above changes on the output results at the workstation is significant. If the significance is greater than the confidence coefficient, the production execution system will prompt the manager that the change of the above two input data has a significant impact on the output result of a certain station. Through the metho...

Embodiment 3

[0061] Using the above-mentioned production execution system, this embodiment also provides a method for monitoring production, which is combined below figure 1 , figure 2 and Figure 4 Describes methods for monitoring production.

[0062] Execute step S11, refer to figure 1 As shown in , the data collection module 10 automatically collects the input data and output data of a station in the production line, and this step is the same as that in Embodiment 1, and will not be repeated here. The input data includes several parameters, each parameter has a plurality of set values, several combinations are formed between each set value of each parameter, and the input data formed by each combination produces several batches of products. For example, in this embodiment, take raw material A and raw material B of station 1 as an example for illustration, raw material A is provided by two suppliers, namely supplier A and supplier B, and raw material B is provided by two suppliers, n...

Abstract

The invention provides a production executing system, a method for monitoring data exception and a method for monitoring production; the production executing system comprises a data collecting module, a calculating module, a comparison module, and a reminding module; the data collecting module is used for collecting input data and output data on every work station on a production line; the calculating module is used for calculating the significance of the output data; the comparison module is used for comparing the significance with a confidence coefficient; the reminding module is used for sending the reminding information if the absolute value of the significance is more than or equal to the confidence coefficient of the confidence factor. Through data collection and analysis in production process, the exception of the production data can be independently monitored, the problem reason can be found, thereby providing guidance for production and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a production execution system, a method for monitoring abnormal data and a method for monitoring production. Background technique [0002] In today's industrial automation field, in order to increase competitiveness, manufacturing companies need to simultaneously reduce time to market, increase process visibility and production flexibility, optimize forecasting and scheduling, and reduce scrap, inventory levels and downtime to ensure product quality quality and production efficiency. Therefore, in order to meet these demand goals, the production execution system is usually used in the manufacturing industry to manage production. The production execution system can record the raw material information, station information and station results of each process in the production line, and effectively guide the production of the factory. Operation process, so that it can ...
