Description

Monitoring system and method thereof

The invention relates to a monitoring system and a method thereof, in particular to a monitoring system and method thereof for accurately comparing a real production situation of a production line with a standard process to effectively help a manager to understand the production operation process at any time. .

With the evolution of the times, the process of technological products has become more and more complicated and sophisticated. Among them, the production process of the technology product is divided into a plurality of production processes by the production line to standardize and accelerate the process of the technology product, which is a method of frequent use.

However, the existing production lines often waste because of the inability to immediately discover problems or malfunctions in one of the production processes. What's more, when a machine responsible for a production process in a production line fails, it may be caused by more serious damage due to continuous operation, and even cause interruption of the production line. Therefore, the current production line is greatly limited in application, which is one of the major problems that need to be overcome.

As described above, the inventors of the present invention have conceived and designed a monitoring system and a method thereof to improve the lack of the prior art, thereby enhancing the industrial use and utilization.

In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a monitoring The system and its method to solve the problem that the prior art cannot be immediately discovered and processed when a problem or failure occurs in the production line.

According to the purpose of the present invention, a monitoring system is provided, which is suitable for use in a production line, and comprises: at least one camera module, a storage module and a processing module. At least one camera module separately performs image capture on a plurality of production programs executed in the production line, and correspondingly generates a plurality of image data. The storage module stores each image data and a plurality of standard image data corresponding to each production program. The processing module compares each image data with each corresponding standard image data to selectively generate warning messages corresponding to the respective production programs.

Preferably, the processing module can separately set the threshold value for each production program, and when the processing module compares the image data captured by each production program with the corresponding standard image data, respectively, the comparison difference is generated respectively. Value, and the processing module compares each comparison difference value with each corresponding threshold value. If the comparison difference value exceeds its corresponding threshold value, the processing module generates for the corresponding production program. Warning message.

Preferably, the processing module can immediately compare the received image data with the corresponding standard image data by receiving the first image data.

Preferably, the processing module can further set at least one production program as a key production program. When the warning message generated by the processing module is a corresponding key production program, the processing module generates a stop message to suspend the operation of the production line.

Preferably, when the number of occurrences of the warning message corresponding to a certain production program exceeds a preset value, the processing module can set the production program as a key production program.

Furthermore, according to the object of the present invention, a monitoring method is proposed, which is suitable for a production line. The method includes the following steps: performing image capture on a plurality of production programs executed in the production line through at least one camera module, and respectively generating a plurality of image data; storing each image data through the storage module and correspondingly a plurality of standard image data of the production process; and comparing each image data with each corresponding standard image data through the processing module to selectively generate warning messages corresponding to the respective production programs.

The technical features, contents, and advantages of the present invention, as well as the advantages thereof, can be understood by the present inventors, and the present invention will be described in detail with reference to the accompanying drawings. The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

Please refer to FIG. 1, which is a block diagram of the monitoring system of the present invention. As shown in the figure, the monitoring system 1 of the present invention comprises a camera module 11, a storage module 12 and a processing module 13. The camera module 11 can capture images of various production programs in the production line to correspondingly generate image data 111. The storage module 12 stores the image data 111 and standard image data 112 corresponding to each production program. The processing module 13 compares the image data 111 generated by each production program and the standard image data 112 corresponding to each production program to selectively generate the warning message 131 for each production program.

Please refer to FIG. 2, which is a schematic diagram of an embodiment of a monitoring system of the present invention. As shown in the figure, the monitoring system of the production line is provided with a plurality of camera modules 23, and each camera module 23 captures images of a plurality of production programs 21 in the production line and forms image data. The image data can be stored in the storage module for a long time, so that the image data at a certain point in time can be read at any time, and the status of the production program 21 corresponding to the image data is confirmed at that time. The storage module stores standard image data corresponding to each production program 21, so that the processing module can compare the corresponding image data and the standard image data for each production program 21, and generate a comparison difference value. The larger the difference value of the comparison corresponding to a certain production program 21, the higher the difference between the actual production situation of the production program 21 and the standard process. If the ratio of the difference corresponding to a certain production program 21 exceeds the threshold set by the processing module for the production program 21, the processing module will issue a production program 21 A warning message. The warning message can be a light signal, a warning tone or a combination thereof, but is not limited thereto.

It is worth mentioning that the threshold set by the processing module for each production program 21 can be adjusted separately according to the importance of the production program 21. For example, if a production program 21 is less important, the processing module can set its corresponding threshold to be higher, that is, when the processing module performs image comparison for the production program 21 and generates a comparison difference. At the time of the value, the comparison difference value is less likely to exceed the threshold value and the processing module issues a warning signal. In other words, since the production process 21 is less important, the actual production situation that can be tolerated is quite different from the standard process. In the larger difference range, no warning message is generated, and vice versa.

Incidentally, when the camera module 23 generates image data and stores it in the storage module, the processing module also instantly compares the image data in the storage module and its corresponding standard image data. By instant image comparison, when the actual production situation of a production program 21 is too different from the standard process, the processing module can immediately generate a warning message so that the line manager can respond to the warning message as early as possible. .

In addition, there are certain production processes 21 in the production line. In the event of a malfunction or error, if the production line is not immediately suspended, it will cause additional damage to the production line or even damage the operation of the production line. For the production programs 21, if the processing module finds an error by comparing the images, only the warning message is insufficient. Therefore, the processing module can set such a production program 21 as the key production program 22. When the processing module finds the difference between the actual production situation of the key production program 22 and the standard process by the image comparison method, the difference between the actual production situation and the standard process exceeds the tolerance range, that is, when the comparison error value corresponding to a certain key production program 22 exceeds the corresponding key production. The threshold of the program 22, the processing module is in addition to the key The production program 22 generates a warning message to alert the manager to generate a stop message to temporarily suspend the operation of the production line to avoid further damage from the failure of the key production program 22.

Incidentally, when some production programs 21 frequently make mistakes such that the number of warning signals generated for the production program 21 exceeds a predetermined value, the processing module can set the production program 21 as the key production program 22. When the production program 21 (which has been set as the key production program 22), an error occurs again, that is, the processing module again issues a warning message to the production program 21, and the processing module will issue a stop message to suspend the production line. Easy troubleshooting or error handling.

Although the foregoing description of the monitoring method of the present invention has been described in the foregoing description of the monitoring system of the present invention, for the sake of clarity, the flowchart will be described in detail below.

Please refer to FIG. 3, which is a flow chart of the steps of the monitoring method of the present invention. As shown in the figure, the monitoring method of the present invention comprises the following steps: in step S11, image capture is performed on a plurality of production programs executed in a production line through at least one camera module, and corresponding plurality of image data are respectively generated.

In step S12, each image data and a plurality of standard image data corresponding to each production program are stored by the storage module.

In step S13, each image data is compared with each corresponding standard image data through the processing module to selectively generate warning messages corresponding to the respective production programs.
