[0015] The embodiments will be described in detail below with reference to the drawings. The embodiments described below all represent preferred specific examples of the present invention. The numerical values, shapes, components, arrangement and connection configurations of components, steps, and the order of steps shown in the following embodiments are examples only and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, those not described in the independent claims representing the highest-level concept of the present invention will be described as any component constituting a more preferred form. Note that identical components may be denoted by the same reference numeral and their descriptions may be omitted. [Embodiment]

[0016] Figure 1 is a schematic diagram showing an overview of a transport trolley travel system according to an embodiment of the present invention. As shown in Figure 1, the transport trolley travel system 100 includes transport trolleys 101a to 101d (collectively referred to as transport trolley 101), a control server 102, an operation terminal 103, wireless access points 104a and 104b (collectively referred to as wireless access point 104), and a travel track 107. In addition, multiple areas along the travel track 107 may be equipped with devices (for example, semiconductor manufacturing equipment (not shown)) that provide or receive materials and manufactured goods for transport by the transport trolley 101. The travel track 107 includes track modules 106a to 106g, which will be described later.

[0017] The operating terminal 103 is a communication terminal operated by the user 105, which displays a screen showing the travel status of the transport trolley 101 based on log information collected by the control server 102, and sends instructions to the control server 102. The operating terminal 103 is, for example, a personal computer, a tablet computer, or a smartphone.

[0018] The control server 102 is a server device that performs various controls on multiple transport trolleys 101 located on the travel track 107 and collects information on the operating status of the transport trolleys 101. The control server 102 is connected to the transport trolleys 101 via a wireless access point 104, which will be described later, and sends control commands to the transport trolleys 101. The control server 102 also collects information on the operating status of the transport trolleys 101 (for example, track modules in motion) and, based on instructions from the user 105, transmits the collected operating status information to the operation terminal 103 via the wireless access point 104.

[0019] Transport trolleys 101a to 101d are vehicles that travel on the travel track 107, and are, for example, suspended hoist transport trolleys (OHT (Overhead Hoist Transport) trolleys). Transport trolley 101 travels without a person on board and is a vehicle that travels autonomously or based on remote control (for example, control commands transmitted by the control server 102). Multiple transport trolleys 101 exist on the travel track 107. Each transport trolley 101 is identified by a transport trolley identifier, such as a unique number.

[0020] The travel track 107 is the physical path for the transport trolley 101 to travel. The travel track 107 is mainly installed on the ceiling or floor of a facility such as a factory. The travel track 107 may be realized by suspension rails, guide magnetic tapes, and rails.

[0021] Track modules 106a to 106g (collectively referred to as track module 106) represent logical units used by the control server 102 to manage the travel track 107 by dividing it into separate areas. Each track module 106 is identified by a unique number, such as a track module identifier. The movement of a specific transport trolley 101 across the boundary of one track module 106 to another track module 106 is called "transfer".

[0022] Here, the transfer process will be explained using Figure 3. Figure 3 is a schematic diagram showing an enlarged portion of the travel track of the transport trolley travel system 100 shown in Figure 1. The arrows 301a to 301c in Figure 3 represent the directions of travel of the transport trolleys 101a to 101c, respectively. Figure 3 also shows the transfer process where the transport trolley 101a travels in the direction of travel 301a, crosses the boundary of track module 106g, and enters track module 106a. Similarly, the transfer process for the transport trolley 101c is shown when it travels in the direction of travel 301c, crosses the boundary of track module 106g, and enters track module 106b. The transport trolley 101b is shown traveling within track module 106g in the direction of travel 301b.

[0023] Returning to Figure 1, multiple wireless access points 104 are installed near the travel track 107 and communicate wirelessly with the transport cart 101 based on a predetermined wireless communication standard (e.g., IEEE802.11ac). Specifically, the wireless access points 104 are wired to the control server 102 and relay control commands transmitted by the control server 102 to the transport cart 101, and relay information about the operating status of the transport cart 101 transmitted by the transport cart 101 to the control server 102. The wireless access points 104 also play a role in relaying communication between the operation terminal 103 and the control server 102. Note that the communication relayed may be configured such that a single wireless access point 104 relays communication between the transport cart 101 and the control server 102, and communication between the operation terminal 103 and the control server 102. Alternatively, the relay of communication between the transport trolley 101 and the control server 102, and the relay of communication between the control server 102 and the operation terminal 103 may be exclusively performed by individually assigned wireless access points 104.

[0024] Figure 2 is a block diagram showing the functional configuration of an operating terminal according to an embodiment of the present invention. As shown in Figure 2, the operation terminal 103 comprises an acquisition unit 201, an extraction unit 202, a control unit 203, a storage unit 204, an event determination unit 205, a generation unit 206, a display unit 207, and an input unit 208. Each of the above functions in the operation terminal 103 is realized by hardware such as the CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), auxiliary storage device (eMMC (Embedded Multimedia Card)), non-volatile storage means such as an SSD (Solid State Drive), and a communication module, and by the CPU reading programs stored in ROM and executing them in cooperation with this hardware.

[0025] The acquisition unit 201 acquires event logs related to the travel status of the transport trolley 101, which are recorded by the control server 102 when controlling the transport trolley 101. The acquisition unit 201 is implemented, for example, by a wireless communication interface (not shown) that conforms to a wireless communication standard such as IEEE802.11ac. When the acquisition unit 201 acquires an event log, the storage unit 204 saves the acquired event log. An event log is a log file that records, in chronological order, the time when an event corresponding to a relevant event identifier occurs, based on a predefined "event identifier" associated with various situations (called events) that may occur while the transport trolley 101 is traveling on the travel system 100, and additional information associated with that event (for example, the identifier of a specific transport trolley 101, travel position information, the track module identifier during travel, etc.). The event log is recorded on the transport trolley 101 or the control server 102. The set of event identifiers and additional information recorded for each event that is stored in the event log will be called "event information".

[0026] The memory unit 204 stores event logs related to the driving status of the transport trolley 101, control commands related to the control of the transport trolley 101, and event identifiers. The memory unit 204 also stores bitmaps and the like, which are components (display elements) used to draw the driving status display screen 400. The memory unit 204 may be composed of volatile memory such as RAM, or of non-volatile memory such as eMMC.

[0027] The control unit 203 extracts the event identifier to be extracted (for example, the identifier of a specific transport trolley 101, a transfer event, the track module identifier before the transfer, the track module identifier after the transfer, etc.) selected by the input unit 208 (described later), and the event log stored in the storage unit 204, into the extraction unit 202 Notify them.

[0028] The extraction unit 202 extracts event information to be output from the event log based on the input information from the input unit 208 notified by the control unit 203. More specifically, it extracts event information from the event log in chronological order for a specific track module 106 or a specific transport trolley 101 desired by the user 105. Once the extraction unit 202 has extracted the event information, it notifies the event determination unit 205 of the event information.

[0029] The event determination unit 205 determines whether a transfer event has occurred for a specific transport cart 101 based on the event information notified by the extraction unit 202. More specifically, it uses the event information extracted by the extraction unit 202 to determine whether a transfer event has occurred for each specific transport cart 101 or each specific track module that the user wishes to view. Once the event determination unit 205 has determined whether a transfer event has occurred, it notifies the generation unit 206 of the result of the determination so that the result can be reflected in the data for rendering.

[0030] The generation unit 206 generates drawing data necessary to illustrate the driving situation, including the transfer event of the transport trolley 101. The generation unit 206 also generates display data for display on the display unit 207 based on the drawing data and display elements, and notifies the display unit 207. Drawing data refers to coordinate information necessary to place each display element, such as buttons and text boxes, for drawing visual display information such as a GUI (Graphical User Interface) on the driving situation display screen 400. Display data refers to data in which the display elements are placed at the coordinate positions determined by the aforementioned coordinate information.

[0031] The display unit 207 illustrates information regarding the travel status of the transport trolley 101 to the user 105 based on the display data generated by the generation unit 206. The display unit 207 may be implemented using an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode) display, or the like.

[0032] The input unit 208 receives information from the user 105 regarding the running status of the transport trolley 101 and notifies the control unit 203 of the request containing the received information. More specifically, for example, the user 105 inputs information via the input unit 208, including a specific event identifier or specific event information that they wish to view, the identifier of the track module 106, and the identifier of a specific transport trolley 101. Subsequently, the input unit 208 notifies the control unit 203 of the request containing the input information in order to identify the event information that the event determination unit 205 will extract. The input unit 208 may be implemented in a visual form, such as a GUI, or in an interactive form through a console screen, such as a CUI (Character User Interface). The input unit 208 may also be implemented by hardware such as a tactile switch or a touchscreen.

[0033] Next, using Figure 4, we will explain the display screen showing the travel status of the transport trolley, which is illustrated on the display unit of the operating terminal according to this embodiment. As shown in Figure 4, the running status display screen 400 includes module display axes 401a to 401d corresponding to track modules 106a to 106d, running displays 402a and 402b for transport trolleys 101a and 101b, transfer event messages 403a and 403b, a time marker 404, and a legend display unit 405.

[0034] The module display axes 401a to 401d (collectively referred to as module display axis 401) correspond to the respective track modules 106a to 106d on which the transport trolley 101 travels, and each vertical axis (downward-pointing arrow) indicates the passage of time as it progresses downwards.

[0035] The running indicators 402a and 402b (collectively referred to as running indicators 402) indicate that the transport trolleys 101a and 101b are staying in a specific track module 106, and are located on the module indicator axis corresponding to the track module 106 in which the transport trolley 101 is staying. in, Length of stay toThe corresponding diagrams are shown. To identify the travel indicator 402 for each transport trolley 101, the diagrams may be illustrated using a shading method as shown in Figure 4, or by coloring the vertical axis of the module indicator axis 401. The legend and case example display section 405 represents the distinction in the display method of the travel indicator for each transport trolley.

[0036] Possession event messages 403a-403 b A transfer event message (collectively referred to as a transfer event message 403) displays a transfer event for a specific transport trolley 101 using an arrow pointing from the pre-transfer module to the post-transfer module and the transfer event time. In Figure 4, for example, transfer event message 403a illustrates that a transfer event for transport trolley 101a, corresponding to the travel display 402a, occurred at the time "12:34:56.000" from track module 106a to track module 106b. The transfer event message 403 is also illustrated at a coordinate position on the module display axis 401 corresponding to the time when the transfer event for a specific transport trolley 101 occurred. For example, for each specific transport trolley 101, it is illustrated using an arrow pointing from the pre-transfer track module to the post-transfer module. By including the time when the transfer event occurred in the corresponding transfer event message 403, the user can visually understand when the transfer event occurred. In the embodiment of the present invention, as shown in Figure 4, the transfer event message is illustrated with an arrow, but it is not limited to this, and any other type of line such as a solid line, dotted line, or dashed line may be used. table You may use the symbol.

[0037] The time marker 404 indicates a reference time for displaying the driving status display screen 400. For example, the time marker 404 may indicate the time of the incident when displaying the driving status when a specific incident occurs, such as a collision between two transport trolleys 101 on the transport trolley driving system 100, or it may indicate the time of the event associated with specific event information specified by the user 105.

[0038] The legend display unit 405 shows the association between a specific driving display 402 displayed on the driving status display screen 400 and a specific transport trolley 101.

[0039] The scroll bar 406 moves the display position of the driving status display screen 400 vertically along the module display axis 401. If the position where the event information that user 105 wishes to view is illustrated on the module display axis 401 is far from the reference time indicated by the marker 404, the driving display 402 may be drawn outside the driving status display screen 400. In this case, user 105 may use the scroll bar 406 to adjust the display position so that the event information that user 105 wishes to view can be displayed. Alternatively, the scroll bar 406 may be positioned horizontally and configured to move the display position of the driving status display screen 400 horizontally (not shown). [Description of the flow chart related to the embodiment]

[0040] Next, using Figure 5, we will explain the series of processes from when the operating terminal 103 obtains an event log related to the travel status of the transport trolley 101 from the control server 102, to when it displays the travel status of the transport trolley on the display unit provided by the machine.

[0041] Step S501 is the step in which the acquisition unit 201 acquires an event log related to the transport trolley 101 from the control server 102 and saves the acquired event log to the storage unit 204. Step S501 may be performed periodically at a predetermined time, or it may be performed based on instructions from the user 105 via the input unit 208.

[0042] Step S502 involves the extraction unit 202 and the control unit 203 reading the event log from the storage unit 204. among From input unit 208 、This step involves receiving notifications of multiple or any of the following information for each of the event identifiers to be extracted, the identifier of a specific transport trolley 101, or the identifier of a specific track module 106, and then extracting specific event information. After completing step S502, the operating terminal 103 executes step S600, which is the event determination flow (details will be described separately later).

[0043] Step S503 is when the generation unit 206 uses the event information determined in step S600 as a basis This is the step of generating drawing data for drawing the running status display screen 400. The generation unit 206 determines, for example, the length of the running display 402 for the transporter 101 to be drawn on each module display axis 401, and the coordinates on the running status display screen 400, based on the time information of the module display axis 401 necessary to form the running status display screen 400 based on the time information obtained from the event information extracted by the determination unit 205, and information such as the dwell time of each track module 106 read from the event log related to a specific transporter 101. It also determines the coordinates on the running status display screen 400 for the transfer event message for a transfer event to a new track module.

[0044] Step S504 is a step in which the display unit 207 displays the driving status display screen 400 based on the display data generated by the generation unit 206 in step S503.

[0045] The operating terminal 103 sequentially executes the processes described in steps S501 to S504 above, thereby displaying a running status display screen 400 on the display unit 207 relating to a specific transport trolley 101, a specific track module 106, or a specific event identifier desired by the user 105.

[0046] Figure 6 is a flowchart showing a series of processes in which the transport trolley 101 determines whether a track module has been transferred based on event information received from the extraction unit 202 by the event determination unit 205 of the operation terminal 103. From here, using Figure 6, we will explain the series of processes in step S600 of Figure 5, that is, from when the event determination unit 205 of the operation terminal 103 determines the event information and when the generation unit 206 creates the data for drawing.

[0047] First, in step S601, the event determination unit 205 reads the event information notified by the extraction unit 202 in order to generate drawing data. (Step S601)

[0048] Next, the event determination unit 205 determines, based on the event log, whether or not the transport cart 101 has moved onto a new track module 106 (whether or not a transfer event has occurred) (step S602). More specifically, the event determination unit 205 determines that a "transfer event" has occurred, indicating that the track module 106 has been moved, if it detects event information specific to a transfer (for example, a communication antenna switching event relative to the direction of travel of the transport cart 101, and a barcode reading event, etc.) recorded in the event log by the control server 102 or a specific transport cart 101, or if it is clear from the position information of the transport cart 101 traveling in the event log that it has moved onto the track module 106. Alternatively, the transfer event may be detected by recording event information that includes a specific event identifier defined by the control server 102. If a transfer event occurs in the flow of step S602, execute step S603 (Yes in step S602); if no transfer event occurs, execute step S605 (No in step S602).

[0049] Next, when the event determination unit 205 determines that the next transfer event has occurred, it obtains the time the transfer event occurred from the event log (step S603).

[0050] Next, the event determination unit 205 obtains the identifier of the orbital module 106 before the transfer and the identifier of the orbital module 106 after the transfer from the event logs before and after the transfer event was detected (step S604). On the other hand, if the event determination unit 205 determines in step S602 that no transfer event occurred, it obtains the identifier of the track module that the transport trolley 101 is currently traveling on from the event log (step S605).

[0051] Finally, based on the result of the determination in step S602, the generation unit 206 is notified of the track module information related to the specific transport trolley 101. The generation unit 206 then determines the coordinates and length in the module display axis direction for drawing the travel display 402 related to the travel status of the transport trolley 101, and reflects this in the drawing data (step S606). More specifically, if it is determined in step S602 that a transfer event has occurred, the generation unit 206 is notified of the time the transfer event occurred and the information of the track module 106 that the transport trolley 101 was traveling on before and after that time (track module identifier before transfer and track module identifier after transfer). Based on the notified information, the generation unit 206 determines the coordinates and length for drawing the travel display 402 corresponding to the track module 106 before the transfer and the coordinates and length for drawing the travel display 402 corresponding to the track module 106 after the transfer. Next, the generation unit 206 determines the coordinates to place the transfer event message, including the time and arrow of the transfer event, on the display screen and reflects the result of the transfer event in the drawing data for the running status display screen 400. On the other hand, if it is determined in step S602 that no transfer event occurred, the event determination unit 205 notifies the generation unit 206 of the identifier of the track module 106 that the specific transport trolley 101 is running on, which was acquired in step S605. Based on this notification, the generation unit 206 determines the coordinates for drawing the running display 402 and reflects them in the drawing data.

[0052] Furthermore, the present invention can be implemented not only as a device, but also as a method in which the processing means constituting the device are steps, as a program that causes a computer to execute those steps, as a storage medium such as a computer-readable CD-ROM on which the program is recorded, or as information, data, or signals that represent the program. These programs, information, data, and signals may be distributed via a communication network such as the Internet. [Industrial applicability]
