Smart manufacturing is based on sensing technology, network technology, automation technology, and artificial intelligence, through the process of perception, human-computer interaction, decision-making, execution, and feedback to realize product design and manufacturing, enterprise management and services of wisdom.

The characteristics of small profits but quick turnover and fierce product price competition in the electronic assembly industry make the industry pursue more effective control and optimization of raw materials and production tools, so as to maximize the efficiency of factory production resources. Among them, in the production line of the electronic assembly industry, various control and testing links must be included, for example, the materials that are judged to be problematic are removed from the production line.

Currently, the control of various material handling devices on the production line mostly relies on operational services that are constantly running. If you want to adjust the function of the operation service, such as changing the processing action of one or more material processing devices for one or more specific materials, you can usually only change the code of the operation service, upgrade or update the operation service, and After upgrading or updating the operation service, restart the operation service so that the operation service loads the updated code to change the processing action of one or more item processing devices for the specific item.

Since upgrading the operation service program or updating the code requires stopping the operation service, if the operation service is stopped only for emergency or temporary functions, it may affect the production speed, and may cause greater losses.

To sum up, it can be seen that there has been a problem in the prior art for a long time that function adjustment needs to stop the operation service of the control production line, so it is necessary to propose improved technical means to solve this problem.

The system and method disclosed in the present invention are as above, and the difference between it and the prior art is that the present invention dynamically loads and executes external scripts to change the internal data generated by the internal logic by allowing the operation service that executes the internal logic to change the internal data according to the modified data. The internal data changes the processing action of the production line on the target material corresponding to the internal data, so as to solve the problems existing in the previous technology, and can change the processing action of the operation service on the target material without updating or restarting the operation service. Avoid loss of technical efficacy.

The features and implementation methods of the present invention will be described in detail below in conjunction with the drawings and embodiments, the content is enough to enable anyone familiar with the relevant art to easily and fully understand the technical means used to solve the technical problems of the present invention and implement them accordingly, thereby realizing The effect that the present invention can achieve.

The present invention allows the operation service executed in the production line control device to load and execute an external script (Script), so that the operation service judges whether to change the processing action on the target material on the production line according to the execution result of the external script. Wherein, the production line control device may be a computing device.

The system operation of the present invention will be described below with "Fig. 1" the system architecture diagram of the dynamic loading script mentioned in the present invention to change the material processing action. As shown in "Fig. 1", the system of the present invention is applied in a production line control device 100, and includes an operation service 110 and an external script 130. Wherein, the production line control device 100 can execute one or more sets of computer instructions to generate the operation service 110 .

Operation service 110 is responsible for executing predetermined internal logic to perform predetermined processing actions on one or more materials on the production line, and is also responsible for loading and executing external script 130 to control material processing device 410 to perform unscheduled processing on target materials action.

In some embodiments, the operation service 110 can be further shown in "Fig. 2" the schematic diagram of the elements of the present invention to dynamically load scripts to change material processing actions, including logic execution module 210, script loading module The group 220, the script execution module 230, the condition judgment module 250, and the production line control module 260 will be further described below.

The logic execution module 210 is responsible for executing predetermined internal logic to generate internal data corresponding to one or more materials on the production line. In the present invention, the specific material that meets the conditions is also referred to as the target material. Generally speaking, each material on the production line can correspond to one or more internal objects (Object) generated by the operation service 110. The internal data mentioned in the present invention refers to one or more internal objects corresponding to the target material. The attribute value of the attribute.

The script loading module 220 is responsible for loading the external script 130 . It should be noted that the script loading module 220 dynamically loads the external script 130, rather than loading the external script 130 fixedly. The external script 130 is only loaded when there is an unscheduled processing action, and the script loading module 220 will not load the external script 130 when the material on the production line will perform a predetermined processing action.

The script loading module 220 can continuously check the specific directory storing the external script 130, and load the executable external script 130 when there is an executable external script 130 in the specific directory. More specifically, the script loading module 220 can first determine whether the operation service 110 supports the language of the external script stored in a specific directory, if so, it means that the external script can be executed, and the script loading module 220 can load the external script. script, and if the script loading module 220 determines that the operation service 110 does not support the language of the external script stored in the specific directory, or the script loading module 220 cannot recognize the language of the external script in the specific directory, it means that the external script cannot be executed, the script loading module 220 will not load the external script. Wherein, the specific directory is a storage space in the storage medium, and the storage medium can be set in the production line control device 100, or in a storage device (not shown) connected to the production line control device 100, the present invention There are no particular restrictions.

The script execution module 230 is responsible for executing the external script 130 loaded by the script loading module 220, that is, executing the processing logic recorded in the external script 130, and changing the processing logic generated by the logic execution module 210 according to the processing logic of the external script 130. Internal information 150.

In some embodiments, the script execution module 230 can also choose whether to modify the internal data 150 generated by the logic execution module 210 according to the processing logic of the external script 130 . For example, the script execution module 230 can judge whether to change the internal data 150 according to the return value generated by executing the external script 130, that is, when the return value indicates that the internal data needs to be changed or the return value meets a predetermined condition, the script executes The module 230 can modify one or more internal data 150 , and when the returned value indicates that the internal data does not need to be modified or the returned value does not meet the predetermined condition, the script execution module 230 will not modify the internal data 150 .

In addition, in order to avoid unexpected errors when the script execution module 230 executes the external script 130, causing the operation service 110 to be abnormal or to end the execution, the script execution module 230 can also intercept the execution of the external script 130 when executing the external script 130. An error occurred.

The condition judgment module 250 is responsible for judging whether the internal data 150 generated by the logic execution module 210 or the internal data 150 modified by the script execution module 230 meets the processing conditions. For example, the processing conditions can record one or more numerical values or one or more character strings or one or more calculation formulas, and the condition judging module 250 can judge whether the internal data 150 is consistent with any data recorded in the processing conditions The same or match, if yes, the condition judging module 250 can judge that the internal data 150 meets the processing condition, otherwise, the condition judging module 250 can judge that the internal data 150 does not meet the processing condition. It should be noted that the condition judging module 250 can judge whether the internal data 150 matches one or more processing conditions, and the present invention is not particularly limited, and each processing condition corresponds to one or more processing actions, and the present invention does not subject to the above. Generally speaking, each processing condition can record the corresponding processing action, or other modules such as the production line control module can record the processing action corresponding to the processing condition.

The production line control module 260 can obtain the position of each material on the production line. For example, the production line control module 260 can update the position attribute of the internal object corresponding to each material when each material passes a specific position, for example, write the position information of the specific position into the position attribute. Wherein, the specific location may be a counting point, an inspection point, or an operating device (such as the material processing device 410 ) on the production line, but the present invention is not limited thereto.

The production line control module 260 is responsible for controlling the production line to perform processing actions corresponding to the processing conditions of the internal data 150 on the target material when the condition judging module 250 judges that the internal data 150 meets the processing conditions. For example, the production line control module 260 can generate control messages corresponding to processing actions that meet the processing conditions of the internal data 150, and can communicate with wired or wireless information through the communication module (not shown) of the production line control device 100. The communication method transmits the generated control message to the material processing device 410 installed on the production line, so as to control the material processing device 410 to perform specific processing actions through the control message.

In some embodiments, the production line control device 260 can further determine the position of the target material first, and then perform corresponding processing actions according to the position of the target material. In more detail, the production line control device 260 can first read the attribute value indicating the position of the target material from the position attribute of the internal object corresponding to the target material, and can select the corresponding processing action according to the read attribute value And generate corresponding control information, wherein, the processing actions that can be selected by the production line control device 260 include selecting the material processing device 410 for processing and/or selecting the processing actions performed by the material processing device 410, etc. The present invention does not This is not the limit.

The material processing device 410 can receive the control information sent by the production line control module 260, and can perform specific processing actions on the target materials on the production line. For example, the material processing device 410 can remove the target material from the production line, so that the target material does not continue to move along with the production line; the material processing device 410 can also place the target material at a specific position on the production line , such as moving the target material to a location where the target material previously passed to re-enter a device that the target material has previously passed, or to skip a specific device after a device that the target material has not previously passed device, or move the target material to the manual processing area, etc. Wherein, the material processing device 410 can perform corresponding processing actions on the target material according to the received control information.

Next, an embodiment is used to illustrate the operating system and method of the present invention, and please refer to "FIG. 3A" for the flow chart of the method for dynamically loading scripts in the present invention to change material processing actions. In this embodiment, it is assumed that the operation service 110 in the production line control device 100 is developed using C# language, but the present invention is not limited thereto.

When the production line control device 100 starts to operate, the operation service 110 in the production line control device 100 can operate according to a predetermined internal logic, and can generate corresponding internal objects for each material on the production line. In this way, the operation service 110 The logic execution module 210 can execute predetermined internal logic to generate internal data corresponding to each material on the production line (step 310 ). In this embodiment, it is assumed that the logic execution module 210 can generate an internal object containing multiple attributes, including but not limited to type, manufacturer, serial number, serial number, specification, production parameters (such as hide), location, and so on.

Also after the production line control device 100 starts to operate, the script loading module 220 in the operation service 110 can also dynamically load the external script 130 (step 320 ). In this embodiment, it is assumed that the script loading module 220 can continue to connect to the storage device through the network at regular intervals and check whether the executable external script 130 is stored in the specific directory of the storage device. If not, then End the current execution, so that the production line operates according to the predetermined program, if so, the script loading module 220 can load the external script 130, for example, use the function CSSScript.Evaluator.LoadCode () in the C# language to load a specific directory External script 130 in . If the materials on the production line are all normal, then each material can be successfully assembled into a commodity, and the script loading module 220 cannot detect the external script 130 usually, that is, the script loading module 220 does not have the external script 130 to load; If there are target materials on the production line (such as the memories with numbers "6051B1095301" and "6Y21B0416101") that are confirmed not to be assembled on the product before they are assembled into the product, the production line will Relevant personnel or a communication device (not shown) outside the production line can transmit the external script 130 to a specific directory of the storage device, so that the script loading module 220 can load the external script 130 from the specific directory of the storage device.

After the script loading module 220 of the operation service 110 loads the external script 130, the script execution module 230 of the operation service 110 can execute the external script 130 to change the internal data 150 produced by the logic execution module 210 of the operation service (step 330). In this embodiment, it is assumed that the script execution module 230 can detect whether the process of executing the external script 130 occurs when executing the loaded external script 130 (step 331) as shown in the flow of "Fig. 3B". An unexpected error (step 333), if so, the script execution module 230 can intercept the error (step 335), for example, intercept the error that occurs in the execution of the external script 130 through the syntax of try-catch, and can intercept the error End the execution of the external script 130; and if there is no unexpected error in the process of executing the external script 130 by the script execution module 130, and the external script 130 can generate a return value after being executed, then the script execution module 130 The return value generated by 130 determines whether to change the internal data 150 (step 337). For example, the external script 130 can check whether the attribute value of the serial number attribute of each internal object is "6051B1095301" or "6Y21B0416101" (and the external script 130 It is also possible to check whether the attribute value of the type attribute of the internal object is represented as memory), if not, if the return value is false, that is, the external script 130 judges that the attribute value of the number attribute of the currently checked internal object is not "6051B1095301" and "6Y21B0416101", the script execution module 230 may not change any attribute value (internal data) of any internal object, and if the return value is true, that is, the external script 130 judges the attribute of the serial number attribute of the internal object currently checked If the value is "6051B1095301" or "6Y21B0416101", the script execution module 230 can change the attribute value (internal data 150) of the hide attribute of the same internal object to true (step 339).

Returning to "Figure 3A", after the script execution module 230 of the operation service 110 changes the internal data 150 generated by the logic execution module 210 of the operation service, the condition judgment module 250 of the operation service 110 can judge the script execution module 230 Whether the modified internal data 150 meets the processing conditions (step 350). In this embodiment, assuming that the condition judging module 250 includes multiple processing conditions, one of which is that the attribute value of the hide attribute of the internal object is true, the condition judging module 250 can judge that the attribute value of the serial number attribute is " The attribute value of the hide attribute of the internal object of 6051B1095301" or "6Y21B0416101" meets the processing conditions.

When the condition judgment module 250 of the operation service 110 judges that the internal data 150 meets the processing conditions, the production line control module 260 of the operation service 110 can control the production line to perform processing actions corresponding to the processing conditions for the target material (step 360). In this embodiment, assuming that the production line control module 260 can record the processing action corresponding to the processing condition, the production line control module 260 can read the processing action corresponding to the processing condition whose attribute value of the hide attribute is true, for example , to move the target material out of the production line. In this way, the production line control module 260 can be based on the specific material corresponding to the internal object with the attribute value of the hide attribute on the production line (that is, the target material with the number "6051B1095301" or "6Y21B0416101") item) (the attribute value of the position attribute of the internal object whose attribute value is true for the hide attribute) controls the material processing device 410 on the production line to perform processing corresponding to the processing condition for the target material whose attribute value is true for the hide attribute The action is to move the target material with the number "6051B1095301" or "6Y21B0416101" out of the production line, so that the target material with the number "6051B1095301" or "6Y21B0416101" will not be assembled into the product, so as to avoid the shipment of the product containing the problematic Target item numbered "6051B1095301" or "6Y21B0416101".

In this way, through the present invention, specific processing logic can be imported into the production line through external scripts without updating or restarting the operation service, so as to adjust the processing actions scheduled by the production line for specific materials.

In summary, it can be seen that the difference between the present invention and the prior art lies in that the operation service with internal logic can dynamically load and execute external scripts to change the internal data generated by the internal logic, so as to change the production line according to the modified internal data. The technical means of the processing action of the target material corresponding to the internal data can solve the problem in the previous technology that the function adjustment needs to stop the operation service of the control production line, and then achieve no update or restart The operation service changes the processing action of the operation service on the target material to avoid loss of technical efficiency.

Furthermore, the method of dynamically loading scripts of the present invention to change material processing actions can be implemented in hardware, software, or a combination of hardware and software, and can also be implemented in a centralized manner in a computer system or distributed with different components Implemented in a decentralized manner over several interconnected computer systems.
