[0029] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] In the drawings, functionally identical elements are sometimes represented by the same reference numerals. In addition, the drawings show implementation methods and structural examples according to the principles of the present invention, but these are only used to understand the present invention and are not used to limit the present invention. The description of this specification is only a typical example and does not limit the claims or application examples of the present invention in any sense.

[0031] In the present embodiment, the invention is described in full detail in order to enable those skilled in the art to implement the invention, but it is necessary to understand that other embodiments can also be implemented, and changes in structure / construction and replacement of various elements can be made without departing from the scope and spirit of the technical idea of ​​the invention. Therefore, the following description should not be limited to this for interpretation.

[0032] In addition, for the sake of ease of explanation and observation, the accompanying drawings only show the structural units and their connection relationships required for explanation, and in terms of the product, not all structural units and their connection relationships, such as control lines and information lines, may be shown.

[0033] Figure 1 Schematic diagram showing an existing pull-cord mode andlighting system. Figure 1 In the pull-rope mode andon system, the pull-rope switch (also called "emergency stop switch"), the warning signal light (also called "signal light"), and the production board (also called "signal board") placed at a high place are included. The production board displays multiple lines of information about the corresponding workstation or machine. When a worker finds that a machine failure has occurred at a certain workstation, the warning signal light can be activated by pulling the rope switch. When the warning signal light is on, it means that there is a problem at the workstation and the management personnel need to go to deal with it. After the problem is solved, the pull rope can be pulled to resume production.

[0034] Figure 2 The structural block diagram of the existing pull-cord mode andlight system is shown. In the existing pull-cord mode andlight system 200, for example, pull-cord switches 201-1, 201-2, ..., and 201-N (hereinafter referred to as "pull-cord switches 201" when no distinction is made) are respectively provided at several workstations on the production line. In addition, the pull-cord mode andlight system 200 also includes signal lights 202-1, 202-2, ..., and 202-N (hereinafter referred to as "signal lights 202" when no distinction is made) arranged in association with the pull-cord switches 201-1, 201-2, ..., and 201-N. For example, a pull-cord switch 201 can control the lighting / extinguishing of a signal light 202 through a PLC signal. The pull-cord mode andlight system 200 also includes one or more production kanbans 203 that display information of the corresponding workstations.

[0035] When the operator needs help, finds problems or abnormal conditions related to product manufacturing and quality (for example, machine downtime, quality problems, tooling failure, operator delays, and material shortages), the operator activates the andon system by operating a corresponding one of the pull-wire switches 201-1, 201-2, ..., and 201-N (for example, the pull-wire switch 201-1). At the same time, the corresponding one of the signal lights 202-1, 202-2, ..., and 202-N (for example, the signal light 202-1) is lit by the PLC control on the operating station, and the production board 203 of the andon system is also controlled according to the PLC signal, so that the production board 203 displays which station's pull-wire switch is pulled down, and an alarm music sounds. In the production board 203, information such as the station name and the number of abnormalities can be displayed. In addition, the workstation status can be indicated by marking different background colors on the corresponding area of ​​the workstation, for example, a green background indicates normal, a yellow background indicates a call is in progress, etc., but the setting and definition of the background color is not limited to this, and various colors can be set and defined according to needs.

[0036] The broadcast of the production board 203 releases the information to alert everyone. The site manager responds to the quality requirements and identifies the problem with the operator. If the site manager can solve the problem, the rope is pulled down again and the system returns to normal. If the problem must be solved by seeking help from other departments, the site manager may call the call station set up in a fixed area of ​​the production workshop to release the relevant abnormal situation information and call other relevant personnel to deal with the problem.

[0037] However, in the existing pull-cord mode andon system, since the worker activates the signal light by pulling the cord switch and calls the relevant personnel when he finds a machine failure at a certain workstation, it is impossible to promptly notify the relevant responsible personnel of the relevant abnormal situation information, which will prolong the time to deal with the problem and cause waste. At the same time, this model does not provide background data statistical analysis functions and cannot provide data analysis references for production management personnel.

[0038] In addition, when a machine fails, the relevant responsible person may not be at his / her workstation and may not be notified in time. In addition, in work scenarios such as large factories or many workshops, due to the transmission distance limit of the enterprise's internal LAN, when the distance between the responsible person and the failed machine is far enough, the responsible person may not be notified in time because the information needs to be transferred multiple times.

[0039] Figure 3 FIG. 1 is a block diagram showing a schematic structure of a mobile andon system according to an exemplary embodiment of the present invention. Figure 3As shown, the mobile andon system 300 includes one or more andon callers 301 (301-1, 301-2, ..., 301-N), an andon server 305, and one or more andon mobile portable terminals 307 (307-1, 307-2, ..., 307-M). In addition, the mobile andon system 300 may also include a signal light 302 and a production board 303. Regarding the structure and configuration of the signal light 302 and the production board 303, the existing structure and configuration may be adopted.

[0040] One or more andon callers 301 are respectively configured at one or more workstations in the production line. When an abnormal situation occurs in a workstation of the production line, the operator operates the andon caller of the corresponding workstation to trigger the mobile andon system. The andon caller generates an andon call signal related to the abnormal situation and sends it to the andon server 305 via the enterprise internal LAN 304. The andon caller is typically a pull-cord switch, but it can be any device as long as it has the function of triggering the andon system like a pull-cord switch. Andon callers 301-1, andon callers 301-2, ..., andon callers 301-N can be arranged according to the production line site requirements such as production line scale, production line environment, and production line quality requirements. Abnormal situations are various abnormal situations such as machine shutdown, quality problems, tooling failure, operator delays, material shortages, etc. In addition. The andon call signal includes but is not limited to relevant information of the workstation where the abnormal situation occurs: for example, the name of the production line, the name of the workstation, the name of the abnormal situation, the time when the abnormal situation occurs, the duration of the abnormal situation, the time when the abnormal situation is resolved, the abnormal situation processing status, etc. In addition, the enterprise internal LAN 304 can be either a wired LAN or a wireless LAN.

[0041] The Andon server 305 communicates with one or more Andon callers 301 through a local area network such as an internal enterprise local area network 304, receives and stores the Andon call signal sent by the Andon caller 301. Then, the Andon server 305 retrieves the Andon database 3051 that pre-stores association data that associates various Andon call signals with the Andon mobile portable terminals of the corresponding exception handling personnel according to the Andon call signal, thereby determining the Andon mobile portable terminal 307 associated with the received Andon call signal. Then, the Andon server 305 sends the Andon call signal to the determined corresponding Andon mobile portable terminal 307 via the mobile communication network 306. In addition, the Andon database 3051 can also be stored in an external storage device, and the Andon server 305 calls the Andon database 3051 by accessing the external storage device.

[0042] A corresponding Andon mobile portable terminal 307 among Andon mobile portable terminal 307 - 1 , Andon mobile portable terminal 307 - 2 , . . . , andon mobile portable terminal 307 -M receives an Andon call signal from the Andon server 305 .

[0043] The Andon mobile portable terminal 307 includes a control unit 3071 for controlling the overall operation of the Andon mobile portable terminal, a communication unit 3072 capable of communicating using a mobile data communication function based on various mobile communication standards such as 2G, 3G, 4G, and 5G, and a display unit 3073. Under the control of the control unit 3071, the communication unit 3072 receives an Andon call signal from the Andon server 305 through the mobile communication network 306. Then, the control unit 3071 analyzes the Andon call signal, generates abnormal information related to the abnormal situation indicated by the Andon call signal, and displays a screen containing the abnormal information on the display unit 3073.

[0044] The display method of the abnormal information adopted by the display unit 3073 can be the same as Figure 2 The production board 203 is displayed in the same manner as the production board 203 (for example, refer to Figure 4 ). In addition, as needed, the information can be enlarged or reduced for viewing by zooming in and out of the display screen of the display unit 3073.

[0045] Figure 4 An example of a display screen of an ANDON mobile portable terminal according to an exemplary embodiment of the present invention and a screen of an existing production board are shown. Figure 4 In the market, ANDON mobile portable terminal is used with Figure 2 The production board 203 is displayed in the same manner as the production board 203, for example, information such as the production line name and the number of abnormalities are displayed.

[0046] As described above, in the mobile andon system 300 involved in the present embodiment, the andon caller generates an andon call signal related to the abnormal situation when operated by the operator, and sends it to the andon server 305 via the enterprise's internal LAN 304. The andon server 305 searches the andon database 3051 based on the received andon call signal, determines the andon mobile portable terminal 307 associated with the received andon call signal, and sends the andon call signal to the corresponding andon mobile portable terminal 307 via the mobile communication network 306 based on mobile communication standards.

[0047] As a result, the holder of the ANDON mobile portable terminal 307 can determine the location of the abnormal situation as soon as it occurs, and quickly go to the location of the abnormal situation to solve the abnormal situation, which can shorten the time for handling abnormal situations such as faults.

[0048] Moreover, by using the ANDON mobile terminal with mobile data communication function, even if the relevant responsible personnel are not at their workstations when the machine fails, or the transmission distance of the enterprise's internal LAN is limited in work scenarios such as large factories or many workshops, the abnormal situation can be notified to the responsible personnel in a timely manner. As a result, the time for handling abnormal situations such as failures can be further shortened, production efficiency can be improved, production costs can be reduced, and downtime of production lines can be reduced.

[0049] Figure 5 FIG. 1 is a functional block diagram of an ANDON mobile portable terminal according to another exemplary embodiment of the present invention. Figure 5 In the figure, the ANDON mobile portable terminal 507 includes a control unit 5071, a communication unit 5072, a display unit 5073, a prompt unit 5074, a query unit 5075, and a statistics unit 5076.

[0050] The control unit 5071 controls the overall operation of the Andon mobile portable terminal 507. Under the control of the control unit 5071, the communication unit 5072 receives an Andon call signal from the Andon server through the mobile communication network. Then, the control unit 5071 parses the Andon call signal, generates abnormal information related to the abnormal situation represented by the Andon call signal, and displays the screen containing the abnormal information on the display unit 5073. In addition, in order to allow the holder of the Andon mobile portable terminal 507 to view the abnormal information displayed on the display unit 5073 in a timely manner, or to prevent the holder of the Andon mobile portable terminal 507 from missing the abnormal information, the prompt unit 5074 responds to the reception of the Andon call signal and prompts through at least one of various prompting methods such as vibration, sound, flashing light, text message, email, etc., so that the holder of the Andon mobile portable terminal 507 can view and handle the abnormal information in a timely manner. In addition, when prompting via SMS, email, etc., information related to the abnormal situation, such as the production line name, workstation name, time when the abnormality occurred (for example, the time when the andon pager was operated), can also be prompted in text form.

[0051] Figure 6 It is shown Figure 5 An example of an abnormality prompt of the ANDON mobile portable terminal. Figure 6 In the example, the prompting unit 5074 of the ANDON mobile portable terminal 507 prompts that an abnormal situation has occurred through a mobile phone message such as a text message.

[0052] In addition, the query unit 5075 can respond to the user's query request, access the Andon server through the communication unit 5072 and the mobile communication network to obtain query data, and generate an Andon query report (referred to as "Andon report") containing abnormal details such as groups. Among them, various query conditions such as query time period, shift, production line name, group, etc. can be specified in the query request, and the Andon query report lists the query results according to the specified query conditions. In the Andon query report, as needed, abnormal details such as equipment failure, line stop time, fault description, reasons for line stop due to quality problems, shortage of parts supply and reasons for suspension of production can be recorded. By displaying the Andon query report on the display unit 5073 for the responsible personnel to query, the responsible personnel can more comprehensively and accurately determine the abnormal causes and solutions, and further improve the efficiency of handling abnormal situations.

[0053] In addition, the statistics unit 5076 can respond to the user's statistical request, access the Andon server through the mobile communication network via the communication unit 5072 to obtain statistical data, and generate an Andon statistical report containing abnormal historical statistical information such as the number of abnormalities. For example, various statistical conditions such as the statistical time period, shift, production line name, group, etc. can be specified in the statistical request, and the Andon statistical report lists the statistical results according to the specified statistical conditions. In the Andon statistical report, various abnormal historical statistical information related to abnormal situations such as the type, number, and solution of abnormalities that occurred in the past can be recorded as needed. By displaying the Andon statistical report on the display unit 5073 for the responsible personnel to view, the responsible personnel can accurately determine the machines with a large number of failures, etc., and can improve production efficiency and reduce the downtime of the production line by replacing or deeply repairing the corresponding machines.

[0054] in addition, Figure 7 Show Figure 5 An example of the query and statistics screen of the ANDON mobile portable terminal.

[0055] Figure 8 1 is a flowchart showing the workflow of a mobile andon system according to an exemplary embodiment of the present invention. Figure 3 The structure is used to illustrate the steps of the control method of the mobile andon system.

[0056] In step S801 , one or more andon callers 301 arranged at one or more workstations in the production line are operated by an operator to generate andon call signals, which are then sent to an andon server 305 via the enterprise's internal LAN 304 .

[0057] In step S802 , the Andon server 305 communicates with one or more Andon pagers 301 through a local area network such as the enterprise's internal LAN 304 , and receives an Andon call signal sent by the Andon pager 301 .

[0058] In step S803, the Andon server 305 searches the Andon database 3051 according to the received Andon calling signal, and determines the Andon mobile portable terminal 307 associated with the Andon calling signal.

[0059] In step S804 , the Andon server 305 sends the Andon call signal to the corresponding Andon mobile portable terminal 307 via the mobile communication network 306 .

[0060] In step S805 , the Andon mobile portable terminal 307 receives an Andon call signal from the Andon server 305 through the mobile communication network 306 .

[0061] In step S806 , the ANDON mobile portable terminal 307 analyzes the ANDON call signal and displays abnormal information related to the abnormal situation indicated by the ANDON call signal on the display unit 3073 .

[0062] The above is the basic workflow of the mobile andon system.

[0063] In addition, in adopting Figure 5 In the case of the Andon mobile portable terminal 507, it can further include: a prompting step, in which the prompting unit 5074 responds to the reception of the Andon call signal and prompts through at least one of various prompting methods such as vibration, sound, light flashing, text message, and email; a querying step, in which the querying unit 5075 responds to the user's query request and accesses the Andon server through the mobile communication network, generates an Andon query report containing abnormal details information, and displays it on the display unit 5073; and a statistical step, in which the statistical unit 5076 responds to the user's statistical request and accesses the Andon server through the mobile communication network, generates an Andon statistical report containing abnormal historical statistical information, and displays it on the display unit 5073. In addition, in the prompting step, when prompting through text messages, emails, etc., information related to the abnormal situation, such as the production line name, the workstation name, and the abnormal occurrence time, can also be prompted in text form.

[0064] By adopting the above structure and steps, the holder of the Andong mobile portable terminal can determine the location of the abnormal situation as soon as it occurs, and quickly go to the location of the abnormal situation to solve the abnormality, which can shorten the time for handling abnormal situations such as faults.

[0065] Moreover, by using the ANDON mobile terminal with mobile data communication function, even if the relevant responsible personnel are not at their workstations when the machine fails, or the transmission distance of the enterprise's internal LAN is limited in work scenarios such as large factories or many workshops, the abnormal situation can be notified to the responsible personnel in a timely manner. As a result, the time for handling abnormal situations such as failures can be further shortened, production efficiency can be improved, production costs can be reduced, and downtime of production lines can be reduced.
