Description

Technical Field

[0001] The invention belongs to the technical field of production monitoring, and in particular relates to a workstation capacity monitoring system. Background Art

[0002] Resource allocation in the production line has always been an important issue in production and processing. In metal processing, the output speed is limited. It is not as high-speed as the electronics industry. It focuses more on the control of manpower, machines and materials. The manufacturing order (hereinafter referred to as the manufacturing order) is the basis for controlling production line resources. Generally speaking, the number of resources such as workstations, machines, materials and personnel, working hours and output targets will be recorded in the manufacturing order. After the management issues the manufacturing order, the on-site staff can select the corresponding workstations, machines and materials according to the content of the manufacturing order and start manufacturing the product.

[0003] The above-mentioned production orders will be decided by the production management unit, warehouse management unit and financial unit before the machines on the production line are put into operation. When the production order needs to be changed, the personnel need to return the production order to the production management unit and regenerate a new production order and enter it into the back-end server. In the process of generating a new production order, in addition to considering the re-examination and approval of each unit, it may also be necessary to reallocate machines, or there may be a temporary situation where staff need to supervise multiple production lines. Only in this way can the back-end server correctly record the machine utilization rate and man-hours.

[0004] In traditional production lines, the on-duty personnel of the day usually record their personal working hours, product quality, material loss, etc. by handwriting on the whiteboard next to each machine, so as to check with the production order. Although this method has the lowest cost, the calculation of working hours needs to be manually counted, so the accounting department needs to count the total working hours every other day. If there is a staff change on the same day, the working hour statistics will be more complicated. If other machines need to be changed after the line is opened, it will also affect the calculation of the machine utilization rate. Although many manufacturers have introduced enterprise resource planning (ERP) systems and used them for the production of instructions. However, the current ERP system's recording method is fixed. Regardless of whether it is before or after the line is opened, as long as there is a change in the production order, the staff can only return the order to the production management personnel, who will coordinate with the relevant units according to the change content and change the resources required. During this period, it is necessary to re-evaluate the available machines, materials, staff and scheduling time on site. If multiple production orders need to be changed, it is very easy to have difficulty in mobilizing resources and the mobilization is prone to errors. Summary of the invention

[0005] In view of the above problems existing in the prior art, the main purpose of the present invention is to provide a workstation capacity monitoring system to facilitate the allocation and recording of production line resources and realize real-time changes of production orders by the back-end server.

[0027] See also Figures 1 to 5 , a workstation capacity monitoring system 100 provided by an embodiment of the present invention includes:

[0028] It includes at least one workstation and a backend server 130; wherein,

[0029] The work station includes a machine, a work reporting module and an input module. A communication interface of the work reporting module is electrically connected to the input module, and another communication interface of the work reporting module is connected to the communication interface of the back-end server 130 through a local area network, so that when the machine outputs an object, the signal generated by the input module is transmitted to the back-end server 130;

[0030] The backend server 130 further includes a processing unit 131 and a storage unit 132. The processing unit 131 is electrically connected to the storage unit 132 and the backend server 130. The processing unit 131 runs an analysis program 135 in the storage unit 132 to process the received signal and output the target result of the workstation.

[0031] With the above system, the control object at the machine is monitored by the input module. The corresponding signal generated by the input module during control will be transmitted to the back-end server 130 through the reporting module for storage and analysis, and the target result of the analysis output will be sent to the corresponding target user, so as to facilitate the target user to remotely allocate and record production line resources. The back-end server 130 can be used to directly change the production order in real time, the production line is more information-based, the data is more visualized, and the management is more refined, which is conducive to the modern management of the factory.

[0032] See also Figure 1 and Figure 2 Specifically, in this embodiment, the workstation capacity monitoring system 100 includes a first workstation 110, a second workstation 120 and a backend server 130. The first workstation 110 and the second workstation 120 are connected to the backend server 130 via a local area network. Preferably, the backend server 130 has certain open permissions so that it can also accept access from other clients.

[0033] Specifically, in this embodiment, in order to distinguish workstations of different attributes, the workstations are defined as a first workstation 110 and a second workstation 120. The first workstation 110 is a manual feeding machine, while the second workstation 120 is an automatic feeding machine. There is no limit to the number of the first workstation 110 and the second workstation 120, which can be set according to the configuration of the actual on-site environment. In this embodiment, a single first workstation 110 and a single second workstation 120 are used as an example, but the invention is not limited thereto.

[0034] Specifically, in this embodiment, the workstation includes a first workstation 110 composed of at least one first machine 111, a first work reporting module 112 and a first input module 113, wherein the number of the first machine 111 can be set according to the actual production line configuration. The first work reporting module 112 has a first communication conversion unit 112a, a first communication interface 112b and a second communication interface 112c. The first communication conversion unit 112a is electrically connected to the first communication interface 112b and the second communication interface 112c. The type of the first communication interface 112b can be but is not limited to an analog input / output interface (Analog I / O), a digital input / output interface (Digital I / O), a serial interface (Serial Port) or a parallel interface (Parallel Port). The second communication interface 112c is an interface that complies with the Ethernet transmission protocol, so the second communication interface 112c is not limited to a wired connection (cable) or wireless transmission (wireless).

[0035] The first module is electrically connected to the first input module 113 through its first communication interface 112b, and is connected to the local area network (LAN) through its second communication interface 112c, so that when the first machine 111 outputs the first object, the first input module 113 generates a first signal and outputs it to the first reporting module 112; when the first machine 111 outputs the second object, the first input module 113 generates a second signal and outputs it to the first reporting module 112. The first object and the second object are output products produced by the first machine 111. The first object is a general term for normal output good products, and the second object is a general term for defective output products. In the following text, in order to facilitate the distinction between good products and defective products, good products are defined as first objects, and defective products are defined as second objects. Therefore, when the output of the first machine 111 is the first object, the first input module 113 is defined to output the first signal. If the output of the first machine 111 is the second object, the first input module 113 is defined to output the second signal. The first input module 113 can be a single button or a combination of multiple buttons, or a barcode scanner or an RFID card reader. The staff at the first workstation 110 can operate the first input module 113 and determine the corresponding output signal according to the product output status of the first machine 111. Then, the first communication conversion unit 112a of the first reporting module 112 converts the first signal (or the second signal) into an Ethernet packet, and the converted signal is defined as the third signal. The fifth communication interface 133 of the back-end server 130 is connected to the local area network, so the first reporting module 112 sends the third signal to the fifth communication interface 133 of the back-end server 130 through the local area network.

[0036] Specifically, in this embodiment, the first work station 110 also includes a verification module 114 electrically connected to the first work reporting module 112, and the verification module 114 is used to confirm the identity information of the staff, and the verification module 114 confirms the opening time and closing time of the first work station 110, and it will send the aforementioned identity information, opening time and closing time to the back-end server 130 through the first work reporting module 112.

[0037] Specifically, in this embodiment, the workstation includes a second workstation 120 composed of at least one second machine 121, a second work reporting module 122 and a second input module 123, wherein the number of the second machines 121 can be set according to the actual production line configuration. The second reporting module 122 has a second communication conversion unit 122a, a third communication interface 122b and a fourth communication interface 122c, wherein the second communication conversion unit 122a is electrically connected to the third communication interface 122b and the fourth communication interface 122c; wherein the third communication interface 122b is electrically connected to the second input module 123, the fourth communication interface 122c is connected to a local area network, and the local area network is connected to a fifth communication interface 133 of the back-end server 130, so when the second machine 121 outputs a first object, the second input module 123 generates a first signal to the second reporting module 122; and when the second machine 121 outputs a second object, the second input module 123 generates a second signal to the second reporting module 122, and then the second reporting module 122 converts the first signal (or the second signal) into a third signal, and sends the third signal to the back-end server 130.

[0038] Specifically, in this embodiment, the material matching module 124 included in the workstation is arranged in front of the input end of the second machine 121, and is electrically connected to the second reporting module 122 for checking the input materials input into the second machine 121: when the material matching module 124 detects that the input materials do not match the input channel of the second machine 121, it will send a first warning signal to the second reporting module 122, and then the second reporting module 122 will forward the first warning signal to the back-end server 130; if the material matching module 124 detects that the input materials match the input channel of the second machine 121, the material matching module 124 counts the number of input materials and sends the counted number to the back-end server 130. It should be understood that the material matching module 124 can realize the identification of materials by infrared recognition, near-field communication (NFC) or image recognition.

[0039] Specifically, in this embodiment, the backend server 130 includes not only a processing unit 131, a storage unit 132 and a fifth communication interface 133 electrically connected to the processing unit 131, but also an alarm module 134 electrically connected to the processing unit 131. The storage unit 132 stores the analysis program 135 and the target results of each workstation; the fifth communication interface 133 is connected to the local area network to transmit the third signal sent by the first workstation 110 and the second workstation 120; the processing unit 131 converts the third signal of the Ethernet back to the corresponding first signal (or second signal); the processing unit 131 runs the analysis program 135 in the storage unit 132, so that the analysis program 135 can output the target results of the first workstation 110 and the second workstation 120 according to the first signal and the second signal, and then the processing unit 131 determines whether to drive the alarm module 134 to send the target result to the corresponding target user according to the target result.
