Description

Technical Field

[0001] This invention relates to the field of production management technology, and to a production system and control method that can identify the sequence of production equipment. Background Technology

[0002] Manufacturing execution systems (MES) are computerized systems used in manufacturing to track and record the transformation process from raw materials to finished products. The information provided by MES helps manufacturing decision-makers understand how to optimize the current state of the factory floor to increase output. MES can control multiple elements of the production process, such as inputs, personnel, machines, and support services.

[0003] Although many manufacturing companies have already started using MES (Manufacturing Execution System) to control their work sites, there are still many shortcomings. For example, production line sites often need to be rearranged to meet user production needs or adjust product manufacturing formulas. MES cannot detect the arrangement order of each production line site in real time, so manual operation is required, which wastes a lot of manpower, material resources and time. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention relates to a production system capable of identifying the arrangement sequence of production equipment, comprising: multiple production devices and a MES (Manufacturing Execution System) terminal. Each production device has a tag and a reading module. Each tag is disposed on a first side of each production device and stores tag information. Each reading module is disposed on a second side of each production device and is used to read the tags facing the second side. The MES terminal is communicatively connected to each production device and stores preset tag information for one of the tags of each production device, designating one of the production devices as a selected production device. When the reading module of the selected production device fails to read any tag, the reading module uploads a tag unread message to the MES terminal, and the MES terminal sets the device serial number of the selected production device to 1. When the reading module of the selected production device reads the tag of the production device, the reading module obtains the tag information and uploads the tag information of the production device to the MES terminal. When the MES device receives the tag information of the production equipment, it sets the device serial number of the selected production equipment to the device serial number corresponding to the tag information plus 1.

[0005] Specifically, when the tag of the selected production equipment is not read by any reading module, the MES device will set the device serial number of the selected production equipment to the last 1.

[0006] Specifically, the MES device determines whether the tag information of the selected production equipment received by the MES device has changed compared to the preset tag information of the production equipment corresponding to the tag information stored on the MES device. When the MES device confirms that the tag information has changed compared to the preset tag information, the reading module of the selected production equipment rereads the tag of the production equipment and uploads it to the MES device. The MES device then resets the device serial number of the selected production equipment based on the reread tag. When the MES device confirms that the tag information has not changed compared to the preset tag information, the device serial number set by the MES device remains unchanged.

[0007] Specifically, the MES device also finds the device serial number corresponding to the set tag information within the MES device based on the tag information input by the user.

[0008] This invention also provides a control method for a production system capable of identifying the arrangement sequence of production equipment, adapted to a Manufacturing Execution System (MES) terminal. The MES terminal is communicatively connected to multiple production devices. Each production device has a tag and a reading module. Each tag is located on a first side of each production device and stores tag information. Each reading module is located on a second side of each production device and is used to read the tags facing the second side. The method includes: when the reading module of a selected production device does not read any tag, the reading module uploads a tag not read information to the MES terminal, and the MES terminal sets the device serial number of the selected production device to 1. When the reading module of the selected production device reads the tag of the production device, the reading module obtains the tag information and uploads the tag information of the production device to the MES terminal. When the MES terminal receives the tag information of the production device, it sets the device serial number of the selected production device to the device serial number corresponding to the tag information plus 1.

[0009] Specifically, it also includes: when the tag of the selected production equipment is not read by any reading module, the MES device terminal sets the device serial number of the selected production equipment to the last 1.

[0010] Specifically, it also includes: determining, through the MES device terminal, whether the tag information of the selected production device received by the MES device terminal has changed compared to the preset tag information of the production device corresponding to the tag information stored on the MES device terminal. When the MES device terminal confirms that the tag information has changed compared to the preset tag information, the reading module of the selected production device rereads the tag of the production device and uploads it to the MES device terminal, and the MES device terminal resets the device serial number of the selected production device based on the reread tag. When the MES device terminal confirms that the tag information has not changed compared to the preset tag information, the device serial number set by the MES device terminal remains unchanged.

[0011] Specifically, it also includes: finding the device serial number corresponding to the set tag information within the MES device based on the tag information input by the user.

[0012] Compared with existing technologies, the production system of the present invention, which can identify the order of production equipment, determines whether the selected production equipment is at the beginning of the sequence by checking whether the reading module of the selected production equipment can read the tag of the production equipment preceding it. When the reading module does not read any tag, the selected production equipment is at the beginning of the sequence, and the MES device sets the equipment number of the selected production equipment to 1. When the reading module has read the tag of the production equipment preceding it, the selected production equipment is not at the beginning of the sequence. The tag information of the production equipment can be obtained and uploaded to the MES device, whereby the MES device sets the equipment number of the selected production equipment to the equipment number corresponding to the tag information plus 1. By checking whether the tag of the selected production equipment can be read by the reading module of the production equipment following it, the system determines whether the selected production equipment is at the end of the sequence. Furthermore, the production system capable of identifying the arrangement order of production equipment can also determine, via the MES device, whether the quantity of production equipment has changed or the order has been rearranged. Additionally, the production system capable of identifying the arrangement order of production equipment can also perform rapid location and search operations on the production equipment via the MES device.

Figure 1 A flowchart illustrating a control method for a production system capable of identifying the sequence of production equipment. Detailed Implementation

[0014] Some embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Component symbols used in the following description are considered identical or similar when appearing in different drawings. These embodiments are only a part of the present invention and do not disclose all possible implementations of the invention. More precisely, these embodiments are merely examples of the apparatus and methods within the scope of the present invention's patent application.

[0015] Figure 1This is a schematic diagram of a production system 10 capable of identifying the order of production equipment according to an embodiment of the present invention. The production system 10 capable of identifying the order of production equipment according to an embodiment of the present invention includes multiple production equipment 100 and a MES device terminal 200. Each production equipment 100 further includes a tag 111 and a reading module 112. The tag 111 stores tag information, and the reading module 112 is used to read the tag 111 of the preceding production equipment 100 located in the production equipment 100 where the reading module 112 is located. The MES device terminal 200 is communicatively connected to the production equipment 100 and stores preset tag information of the tags 111 of the production equipment 100, designating one of the production equipment 100 as the selected production equipment. When the reading module 112 of the selected production equipment fails to read any tag 111, the reading module 112 uploads unread tag information to the MES device terminal 200, and the MES device terminal 200 sets the device number of the selected production equipment to 1. In other words, when the reading module 112 of the selected production equipment cannot read the tag 111 of the production equipment 100 preceding the selected production equipment, it means that the selected production equipment is already the first one, and there are no other production equipment 100s preceding it. For ease of explanation, the equipment number of the selected production equipment at this time can be set to 1, but it is not limited to this. When the reading module 112 of the selected production equipment reads the tag 111 of the production equipment 100, the reading module 112 obtains the tag information of the tag 111 and uploads the tag information of the production equipment 100 to the MES device terminal 200. In other words, when the reading module 112 of the selected production equipment has already read the tag 111 of the production equipment 100 preceding the selected production equipment, it means that the selected production equipment is not the first one, and the obtained tag information of the tag 111 is uploaded to the MES device terminal 200 so that the MES device terminal 200 can subsequently set the equipment number of the selected production equipment based on the tag information. When the MES device terminal 200 receives the tag information of production device 100, it sets the device serial number of the selected production device to the device serial number corresponding to the tag information plus 1. In other words, when the MES device terminal 200 receives the tag information of production device 100 uploaded by the selected production device reading module 112, the MES device terminal 200 first obtains the device serial number of the production device 100 corresponding to the tag information. Simply put, the MES device terminal 200 first obtains the device serial number of the production device 100 preceding the selected production device. The device serial number of the selected production device is set based on the device serial number of production device 100 plus 1, but is not limited to this. This allows for faster and more flexible production line site layout, enabling synchronization with the MES device terminal 200 and quick location of the required production device 100 corresponding to the tag information. Furthermore, when production device 100 is removed, added, or its order is changed, this will also be synchronized to the MES device terminal 200.Production equipment 100 can be manual production equipment, automated equipment, etc. on the production line, but is not limited to this.

[0016] In one embodiment of the present invention, tag 111 is an electronic tag 111 with identification or reading functions, but is not limited thereto. Tag 111 is installed on a first side of production equipment 100, and tag 111 stores tag information. The tag information contains relevant information about the production equipment 100 where tag 111 is located, which may include the name of the production equipment 100, the arrangement order of the production equipment 100, and the production line plan suitable for the production equipment 100. Of course, users can write the above-mentioned relevant information onto the tag 111 via computer connection using encoding or programming, so that each tag 111 can record relevant information about the production equipment 100 that uniquely corresponds to it. For ease of explanation, the tag 111 in this embodiment has information identification and information recording functions, but is not limited thereto.

[0017] In one embodiment of the present invention, the reading module 112 is a sensor with identification or reading functions, but is not limited thereto. The reading module 112 is installed on the second side of the production equipment 100, and is used to read the tag 111 facing the second side. Simply put, the reading module 112 can only read the tag 111 of the production equipment 100 preceding the production equipment 100 where the reading module 112 is located. The reading module 112 also needs to upload the results read to the MES device terminal 200 so that the MES device terminal 200 can subsequently assign or set the device serial number of the production equipment 100 corresponding to the tag 111. For ease of explanation, the reading module 112 in this embodiment has information identification, information processing, and information transmission functions, but is not limited thereto.

[0018] In one embodiment of the present invention, the MES device terminal 200 is a device terminal with communication functions, mainly used to sort the device serial numbers of the production equipment 100 where the tag information is located according to the tag information of the production equipment 100 uploaded by the reading module 112 of the selected production equipment. Of course, the sorting is arranged by the user according to the production plan to suit the transmission targets of different production equipment 100, in order to ensure that the MES device terminal 200 transmits the product or formula to the production equipment 100. Secondly, the order of the production equipment 100 can be changed according to different production plans, and the MES device terminal 200 can be used to update the device serial numbers of the production equipment 100. This is mainly to allow users to make specific changes according to different standards and requirements of the production line to adapt to the actual production situation, but it is not limited thereto. It should be noted that, for ease of explanation, the serial numbers of each production device 100 can be named using Arabic numerals, such as 1, 2, 3, 4, 5, etc. Alternatively, a combination of one or more of the following formats can be used to name the serial numbers of the production devices 100: uppercase letters, lowercase letters, uppercase numbers, or lowercase numbers, but this is not a limitation. The MES device terminal 200 also needs to determine whether there have been any changes between the received tag information of the production devices 100 and the preset tag information corresponding to the tag information of the production devices 100 stored in the MES device terminal 200, in order to further confirm whether the production devices 100 have been removed, added, or had their order changed. For ease of explanation, the MES device terminal 200 in this embodiment has information query, information transmission, and information recording functions, but this is not a limitation.

[0019] Please see Figure 1In some embodiments of the present invention, the user needs to first sort the production equipment 100 in a simple order, ensuring that one side of the reading module 112 of the production equipment 100 faces the label 111 of another production equipment 100, so that the reading module 112 can read the label 111 of the production equipment 100 preceding the production equipment 100 where the reading module 112 is located. Of course, during the simple sorting of production equipment 100, production equipment 100 can also be removed or added, or the order of production equipment 100 can be changed, to adapt to different production plans on the production line. Furthermore, the MES device terminal 200 also stores preset label information corresponding to the label information of the production equipment 100, so that the MES device terminal 200 can determine whether there are changes in the quantity or order of the production equipment 100. In detail, after the user sorts the production equipment 100, each reading module 112 first reads the tag 111 of the previous production equipment 100. The MES device terminal 200 then sets one of the production equipment 100 as the selected production equipment. If the reading module 112 of the selected production equipment does not read any tag 111, it indicates that the selected production equipment is at the beginning of the sort, and the unread tag information read by the reading module 112 is uploaded to the MES device terminal 200. The MES device terminal 200 also sets the device number of the selected production equipment (where the reading module 112 is located) to 1 based on the unread tag information. If the reading module 112 of the selected production equipment reads the tag 111 of the production equipment 100, it indicates that the selected production equipment is not at the beginning of the sort, and there is a production equipment 100 preceding the selected production equipment in the sort. The reading module 112 of the selected production equipment obtains the tag information of the tag 111 of the preceding production equipment 100 and uploads the tag information to the MES device terminal 200. When the MES device terminal 200 receives the tag information of the production device 100, it searches for the device serial number of the production device 100 corresponding to the tag information and sets the device serial number of the selected production device to be one greater than the device serial number corresponding to the tag information. This facilitates the subsequent sorting of the production devices 100 by the MES device terminal 200 and prevents duplicate or disordered device serial numbers of the production devices 100, but is not limited to this.

[0020] Next, in one embodiment of the present invention, when the label 111 of the selected production equipment is not read by any reading module 112, it means that the selected production equipment is at the end of the sorting, and there is no production equipment 100 after the selected production equipment in the sorting. The MES device terminal 200 sets the equipment number of the selected production equipment to the last 1.

[0021] Through the above operations, the MES device terminal 200 can carefully determine whether the tag information of the production equipment 100 uploaded by the selected production equipment has changed from the preset tag information of the production equipment 100 corresponding to the tag information stored in the MES device terminal 200. For example, this can be used to identify problems such as the production equipment 100 being suddenly removed, added, or having its order changed. When the MES device terminal 200 confirms that the label information has changed from the preset label information, it selects the reading module 112 of the production equipment to reread the label 111 of the production equipment 100 and uploads the reread result to the MES device terminal 200. This allows the MES device terminal 200 to reset the equipment serial number of the selected production equipment based on the reread label 111. Subsequently, the MES device terminal 200 will again check whether the label information has changed from the preset label information. The goal is to ensure that the uploaded label information matches the preset label information, thus confirming that the sorting of the production equipment 100 and the MES device terminal 200 is consistent. This prevents errors in product delivery due to inconsistencies between the sorting of the production equipment 100 and the sorting in the MES device terminal 200, which could affect production efficiency.

[0022] In one embodiment of the present invention, when the MES device terminal 200 confirms that the tag information has not changed from the preset tag information, the device serial number of the selected production equipment set by the MES device terminal 200 remains unchanged. In other words, if the actual sorting of the production equipment 100 is consistent with the sorting of the production equipment 100 set in the MES device terminal 200, and there is no situation where the production equipment 100 is removed, added, or its order is changed, then it is not necessary for the MES device terminal 200 to change the original sorting of the production equipment 100; it is sufficient to maintain the original sorting, but this is not a limitation.

[0023] Next, in one embodiment of the present invention, the MES device terminal 200 can also find the device serial number of the production device 100 corresponding to the set tag information by the user inputting a certain tag information, so that the user can quickly find or quickly locate the arrangement order of one of the many production devices 100 stored in the MES device terminal 200 through the MES device terminal 200, but it is not limited thereto.

[0024] The production system 10 of the present invention, which can identify the arrangement order of production equipment, allows users to promptly obtain relevant information about production equipment 100 through the MES device terminal 200 via the above-described operation process. It can also further confirm whether production equipment 100 has been removed, added, or had its order changed. This only requires the reading module 112 to read the tag 111 and upload the result obtained by the reading module 112 to the MES device terminal 200, which can then confirm whether there have been changes in the quantity or order of production equipment 100. This facilitates the MES device terminal 200 in locating or replacing production equipment 100, thereby simplifying manual adjustments. It is convenient to use and highly practical.

[0025] Please see Figure 2 The following is based on the present invention. Figure 1 This embodiment describes the control method for a production system 10 capable of identifying the arrangement order of production equipment. Adapted to a MES device 200, the MES device 200 is communicatively connected to multiple production equipment 100. Each production equipment 100 has a tag 111 and a reading module 112. The tag 111 is located on a first side of the production equipment 100 and stores tag information. The reading module 112 is located on a second side of the production equipment 100 and is used to read the tag 111 facing the second side. The MES device 200 also stores preset tag information for the tags 111 of the production equipment 100 and selects one of the production equipment 100 as the selected production equipment.

[0026] In step S1, it is determined whether the reading module 112 of the selected production equipment has read the tag 111 of the previous production equipment 100. Specifically, the user first performs a simple sorting of the production equipment 100 and selects one of them as the selected production equipment. The reading module 112 of the selected production equipment then determines whether it has read the tag 111 of the production equipment 100 that precedes the selected production equipment in the sorting. If the tag 111 of the previous production equipment 100 is not read, step S2 is executed. If the tag 111 of the previous production equipment 100 is read, step S3 is executed.

[0027] In step S2, the MES device terminal 200 sets the device serial number of the selected production device to 1. Specifically, after step S1, if the reading module 112 of the selected production device does not read the tag 111 of the production device 100 that precedes the selected production device in the sorting, it indicates that the selected production device is currently at the beginning of the sorting, or in other words, there is no production device 100 preceding the selected production device in the sorting. The reading module 112 uploads the unread tag information of production device 100 to the MES device terminal 200, and the MES device terminal 200 sets the device serial number of the selected production device to 1 based on the unread tag information.

[0028] In step S3, the reading module 112 of the selected production equipment obtains the tag information of the production equipment 100. Specifically, after completing step S1, if the reading module 112 has read the tag 111 of the production equipment 100 that precedes the selected production equipment in the sorting, it indicates that the selected production equipment is not at the beginning of the sorting, or in other words, there is a production equipment 100 preceding the selected production equipment in the sorting. The reading module 112 obtains the tag information of the tag 111 of the production equipment 100 and uploads the tag information to the MES device terminal 200.

[0029] In step S4, the MES device terminal 200 sets the device serial number of the selected production device to the device serial number corresponding to the tag information plus 1. Specifically, when the MES device terminal 200 receives the tag information of the production device 100 uploaded by the reading module 112 of the selected production device, it searches for the device serial number of the production device 100 corresponding to the tag information set in the MES device terminal 200, and sets the device serial number of the selected production device to the aforementioned device serial number of the production device 100 plus 1.

[0030] In step S5, it is determined whether the label 111 of the selected production equipment has been read by the reading module 112 of the next production equipment 100. Specifically, after step S4, it is determined whether the label 111 of the selected production equipment has been read by the reading module 112 of the production equipment 100 that is next in the selected production equipment sequence. If label 111 has not been read by the reading module 112, then step S6 is executed. If label 111 has been read by the reading module 112, then step S7 is executed.

[0031] In step S6, the MES device terminal 200 sets the device serial number of the selected production device to the last 1. Specifically, after executing step S5, if the tag 111 of the selected production device is not read by the reading module 112 of the production device 100 that is next in the selected production device in the sort, it means that the selected production device is at the end of the sort, and the MES device terminal 200 sets the device serial number of the selected production device to the last 1.

[0032] In step S7, the MES device terminal 200 maintains the device sequence number of the selected production device. Specifically, after step S5, when the tag 111 of the selected production device has been read by the reading module 112 of the production device 100 that is next in the selected production device in the sort, it indicates that the selected production device is not at the end of the sort, or that there is a production device 100 next to the selected production device in the sort, and the MES device terminal 200 needs to maintain the device sequence number of the selected production device.

[0033] In step S8, it is determined whether the tag information uploaded by the selected production equipment has changed compared to the preset tag information corresponding to the tag information stored in the MES device terminal 200. Specifically, it is determined whether the tag information of the production equipment 100 uploaded by the selected production equipment has changed compared to the preset tag information of the production equipment 100 corresponding to the tag information stored in the MES device terminal 200. If the tag information has changed compared to the preset tag information, then step S9 is executed. If the tag information has not changed compared to the preset tag information, then it is not necessary to modify the equipment serial number of the selected production equipment.

[0034] In step S9, the MES device terminal 200 resets the device serial number of the selected production device. Specifically, after completing step S8, when the MES device terminal 200 confirms that the tag information has changed from the preset tag information, the reading module 112 of the selected production device needs to reread the tag 111 of the production device 100 and upload the reread result to the MES device terminal 200. The MES device terminal 200 then resets the device serial number of the selected production device again based on the reread result.

[0035] In summary, a production system 10 provides a more convenient way to identify the order of production equipment. By checking whether the reading module 112 of the selected production equipment can read the tag 111 of the production equipment 100 preceding it in the sequence, it can determine whether the selected production equipment is currently at the beginning of the sequence. When the reading module 112 does not read any tag 111, the selected production equipment is at the beginning of the sequence, and the MES device terminal 200 sets the equipment number of the selected production equipment to 1. When the reading module 112 has read the tag 111 of the production equipment 100 preceding it in the sequence, the selected production equipment is not at the beginning of the sequence. The tag information of the production equipment 100 can be obtained and uploaded to the MES device terminal 200, which then sets the equipment number of the selected production equipment to the equipment number corresponding to the tag information plus 1. By checking whether the label 111 of the selected production equipment can be read by the reading module 112 of the production equipment 100 that follows the selected production equipment in the sorting, it can be determined whether the selected production equipment is at the end of the sorting. Furthermore, the production system 10, which can identify the order of production equipment, can also use the MES device terminal 200 to determine whether the quantity or order of production equipment 100 has changed. Additionally, the production system 10, which can identify the order of production equipment, can also use the MES device terminal 200 to perform rapid location and search operations on production equipment 100. This prevents errors in product delivery due to inconsistencies between the sorting and quantity of production equipment 100 and the sorting and quantity in the MES device terminal 200, thereby affecting production efficiency. Moreover, other objects and advantages of the present invention can be further understood from the technical features disclosed in the present invention.
