Description

[Technical field]

[0001] The present invention relates to a communication terminal and a driving status display method. [Background technology]

[0002] Conventionally, a transport vehicle traveling system has been known in which one or more transport vehicles autonomously travel along a track to transport production materials or products. The transport vehicle traveling system includes a control device, which manages and monitors the traveling status of the transport vehicle, and sequentially records various situations that may occur during the control of the traveling transport vehicle and the status of the operation of the transport vehicle as log information. In addition, the transport vehicle traveling system may be composed of multiple track modules logically divided into units in which the traveling range is expanded by extending the track on which the transport vehicle travels, or into sections of a certain area.

[0003] In such a transport vehicle traveling system, information on the operation status of the transport vehicle is displayed on a monitor, etc., so that the manager can easily understand it. Here, Patent Document 1 discloses an operation status display system that specifies and accumulates time information and the position information of the transport vehicle corresponding to the time information every predetermined time, and displays the operation status of the transport vehicle for a specified item at a specified analysis location and time period. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-111381 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the operation status display system disclosed in Patent Document 1 merely illustrates the status of the transport vehicle operating in real time. For example, there is a problem that the manager cannot use log information to look back and grasp the status in order to troubleshoot. In addition, when a trouble occurs while the transport vehicle is traveling while transferring between track modules, it is not possible to know how the transport vehicle has been traveling while transferring between track modules until the trouble occurs.

[0006] The present invention has been made in consideration of the above circumstances, and its main object is to provide a communication terminal that displays the traveling status of a transport vehicle in chronological order, allowing the traveling status to be easily grasped. [Means for solving the problem]

[0007] A communication terminal according to one embodiment of the present invention is a communication terminal in a transport system in which a transport vehicle runs on a running track consisting of a plurality of track modules, which controls the transport vehicle and acquires an event log from a control server that collects an event log of the running status of the transport vehicle, and is equipped with an input unit that accepts a request from a user including specific event information, a specific transport vehicle identifier, or a track module identifier, an extraction unit that extracts the specific event information from the event log based on the request, an event determination unit that determines whether a transfer event has occurred based on the extracted specific event information, and if it is determined as a result of the determination that a transfer event has occurred, notifies information on the transfer event from the event information including the transfer event time, the track module before the transfer, and the track module after the transfer, and a display unit that displays a running status display screen showing the running status of the transport vehicle including a display of the transfer event based on the information about the transfer event.

[0008] With this, the communication terminal can display on its own display unit what track module the transport vehicle transferred from to what track module at what time based on the event log obtained from the control server, thereby improving user convenience.

[0009] A driving status display method according to one embodiment of the present invention is a driving status display method in a communication terminal in a transport system in which a transport vehicle travels on a traveling track consisting of a plurality of track modules, the method acquiring an event log from a control server that controls the transport vehicle and collects an event log of the driving status of the transport vehicle, the method including the steps of: receiving a request including specific event information, a specific transport vehicle identifier, or a track module identifier; extracting the specific event information from the event log based on the request; determining whether a transfer event has occurred based on the extracted specific event information, and if it is determined as a result of the determination that a transfer event has occurred, determining information on the transfer event including the transfer event time, the track module before the transfer, and the track module after the transfer from the event information; and displaying a driving status display screen showing the driving status of the transport vehicle including a display of the transfer event based on the transfer event information.

[0010] This provides the same effects as the above-mentioned communication terminal.

[0011] In addition, the traveling status display screen further includes a module display axis corresponding to a plurality of track modules arranged in parallel along a time axis, a traveling display illustrated on the module display axis of the track module along which the transport vehicle travels based on the event log, and a time marker illustrated perpendicular to the module display axis and indicating a time corresponding to specific event information included in the event information, and the display of the transfer event included in the display step is preferably displayed at a coordinate position corresponding to the time when the transfer event occurred by a transfer event message including an indication pointing from the module display axis of the track module before the transfer to the module display axis of the track module after the transfer, and a time display of the time when the transfer event occurred.

[0012] This makes it possible to more specifically illustrate the traveling status of the transport vehicle over time. Effect of the Invention

[0013] According to the present invention, when an important event occurs, such as during trouble analysis, it is possible to specifically illustrate, based on accumulated log information, which of multiple track modules the transport vehicle was traveling on, thereby improving user convenience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, the embodiment will be specifically described with reference to the drawings. The embodiments described below each show a preferred specific example of the present invention. The numerical values, shapes, components, the arrangement and connection of the components, steps, and the order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, those components that are not described in the independent claims showing the highest concept of the present invention are described as any components that constitute a more preferred embodiment. Note that the same reference numerals are used for the same components, and descriptions thereof may be omitted. [Embodiment Mode]

[0016] FIG. 1 is a schematic diagram showing an overview of a transport vehicle traveling system according to an embodiment of the present invention. 1, the transport vehicle traveling system 100 includes transport vehicles 101a to 101d (collectively referred to as transport vehicles 101), a control server 102, an operation terminal 103, wireless access points 104a and 104b (collectively referred to as wireless access points 104), and a traveling track 107. In addition, in a plurality of areas along the traveling track 107, devices (e.g., semiconductor manufacturing devices (not shown)) that provide or receive materials, products, and the like to be transported by the transport vehicle 101 may be installed. The traveling track 107 includes track modules 106a to 106g, which will be described later.

[0017] The operation terminal 103 is a communication terminal operated by a user 105 to display a screen showing the traveling status of the transport vehicle 101 based on log information related to the transport vehicle 101 collected by the control server 102, and to transmit instructions to the control server 102. The operation terminal 103 is, for example, a personal computer, a tablet computer, or a smartphone.

[0018] The control server 102 is a server device for performing various controls of the multiple transport vehicles 101 present on the travel track 107 and for collecting information on the operation status of the transport vehicles 101. The control server 102 is network-connected to the transport vehicles 101 via a wireless access point 104 described later, and transmits control commands to the transport vehicles 101. The control server 102 also collects information on the operation status of the transport vehicles 101 (e.g., a track module in motion) from the transport vehicles 101, and transmits the collected information on the operation status to the operation terminal 103 via the wireless access point 104 based on an instruction from a user 105.

[0019] The transport vehicles 101a to 101d are vehicles that travel on a travel track 107, and are, for example, overhead hoist transport vehicles (OHT (Overhead Hoist Transport) vehicles). The transport vehicles 101 travel without a person on board, and travel autonomously or based on remote control (for example, control commands transmitted by a control server 102). There are a plurality of transport vehicles 101 on the travel track 107. Each transport vehicle 101 is identified by a transport vehicle identifier, which is a unique number or the like.

[0020] The running track 107 is a physical route along which the transport vehicle 101 runs. The running track 107 is mainly provided on the ceiling or floor of a facility such as a factory. The running track 107 may be realized by a suspended rail, a guide magnetic tape, a rail, or the like.

[0021] The track modules 106a to 106g (collectively referred to as track modules 106) are logical units that allow the control server 102 to manage the traveling track 107 by dividing it into areas. Each track module 106 is identified by a unique number such as a track module identifier. In addition, the movement of a specific transport vehicle 101 across the boundary of a track module 106 to another track module 106 is referred to as "transfer."

[0022] Here, the transfer will be described with reference to FIG. 3. FIG. 3 is a schematic diagram showing an enlarged portion of the travel track of the transport vehicle travel system 100 shown in FIG. 1. Arrows 301a to 301c in FIG. 3 indicate the travel directions of the transport vehicles 101a to 101c, respectively. FIG. 3 also shows a transfer state in which the transport vehicle 101a travels in the travel direction 301a, crosses the boundary of the track module 106g, and enters the track module 106a. Similarly, the transfer state of the transport vehicle 101c, when traveling in the travel direction 301c, crosses the boundary of the track module 106g and enters the track module 106b, is shown. Note that the transport vehicle 101b is shown traveling in the travel direction 301b in the track module 106g.

[0023] Returning to FIG. 1, a plurality of wireless access points 104 are installed near the travel track 107, and perform wireless communication with the transporting vehicle 101 based on a predetermined wireless communication standard (for example, IEEE802.11ac, etc.). Specifically, the wireless access point 104 is connected to the control server 102 by wire, and relays control commands transmitted by the control server 102 to the transporting vehicle 101, and relays information on the operation status of the transporting vehicle itself transmitted by the transporting vehicle 101 to the control server 102. The wireless access point 104 also plays a role of relaying communication between the operation terminal 103 and the control server 102. Note that the communication to be relayed may be configured such that a single wireless access point 104 relays communication between the transporting vehicle 101 and the control server 102 and communication between the operation terminal 103 and the control server 102. In addition, the relay of communications between the transport cart 101 and the control server 102, and the relay of communications between the control server 102 and the operation terminal 103 may be exclusively performed by individually assigned wireless access points 104, respectively.

[0024] FIG. 2 is a block diagram showing a functional configuration of the operation terminal according to the embodiment of the present invention. 2, the operation terminal 103 includes 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. The above-mentioned functions of the operation terminal 103 are realized by hardware such as a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), an auxiliary storage device (embedded multimedia card (eMMC)), a non-volatile storage unit such as a solid state drive (SSD), and a communication module, which the operation terminal 103 includes, and by the CPU reading out a program stored in the ROM and executing the program in cooperation with the hardware.

[0025] The acquiring unit 201 acquires an event log related to the traveling state of the transport vehicle 101 recorded by the control server 102 when the transport vehicle 101 is controlled. The acquiring unit 201 is realized by, for example, a wireless communication interface (not shown) conforming to a wireless communication standard such as IEEE802.11ac. When the acquiring unit 201 acquires the event log, the storage unit 204 stores the acquired event log. Note that the event log is a log file in which, when an event corresponding to an event identifier occurs based on an "event identifier" defined in advance by linking it to various situations (called events) that may occur while the transport vehicle 101 is traveling on the traveling system 100, the time of the event occurrence and additional information associated with the event (for example, an identifier of a specific transport vehicle 101, traveling position information, a track module identifier during traveling, etc.) are recorded in chronological order. The event log is recorded in the transport vehicle 101 or the control server 102. In addition, a collection of the event identifier and additional information recorded for each occurrence of an event stored in the event log is referred to as "event information".

[0026] The storage unit 204 stores an event log related to the traveling state of the transporting vehicle 101, control commands related to the control of the transporting vehicle 101, and event identifiers. The storage unit 204 also stores bitmaps and the like that serve as components (display elements) used to draw the traveling status display screen 400. The storage unit 204 may be configured with a volatile memory such as a RAM, or may be configured with a non-volatile memory such as an eMMC.

[0027] The control unit 203 notifies the extraction unit 204 of the event identifier to be extracted (e.g., information such as the identifier of a specific transport vehicle 101, the transfer event, the track module identifier before the transfer, and the track module identifier after the transfer) selected by instructions from the input unit 208 (described later), and the event log stored in the memory unit 204.

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

[0029] The event determination unit 205 determines whether or not a transfer event has occurred for a specific transport vehicle 101 based on the event information notified by the extraction unit 202. More specifically, the event determination unit 205 determines whether or not a transfer event has occurred for each specific transport vehicle 101 or each specific track module that the user wishes to view, using the event information extracted by the extraction unit 202. When the event determination unit 205 determines whether or not a transfer event has occurred, the event determination unit 205 notifies the generation unit 206 based on the result of the determination so that the result is reflected in the data for drawing.

[0030] The generating unit 206 generates drawing data necessary for illustrating a traveling situation including a transfer event of the transport vehicle 101. The generating unit 206 also generates display data for displaying on the display unit 207 based on the drawing data and display elements, and notifies the display unit 207 of the data. The drawing data refers to coordinate information necessary for arranging each of the display elements, such as buttons and text boxes, for drawing visual display information such as a GUI (Graphical User Interface), on the traveling situation display screen 400. The display data refers to data in which the display elements are arranged at coordinate positions determined by the above-mentioned coordinate information.

[0031] The display unit 207 displays information on the traveling status of the transport vehicle 101 based on the display data of the generation unit 206 for the user 105. The display unit 207 may be realized by an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode) display, or the like.

[0032] The input unit 208 receives each item of information on the traveling status of the transport vehicle 101 desired by the user 105, and notifies the control unit 203 of a request including the received information. More specifically, for example, the user 105 inputs information including a specific event identifier or specific event information that the user 105 desires to view, an identifier of the track module 106, and an identifier of the specific transport vehicle 101, via the input unit 208. Then, the input unit 208 notifies the control unit 203 of a request including the input information in order to specify the event information to be extracted by the event determination unit 205. The input unit 208 may be, for example, a visual aspect such as a GUI, or an interactive aspect through a console screen such as a CUI (Character User Interface). The input unit 208 may also be realized by hardware such as a tactile switch or a touch screen.

[0033] Next, a display screen of the traveling status of the transporting platform vehicle shown on the display unit of the operation terminal according to this embodiment will be described with reference to FIG. As shown in FIG. 4, the traveling status display screen 400 includes module display axes 401a to 401d corresponding to the track modules 106a to 106d, traveling displays 402a and 402b of the transport vehicles 101a and 101b, transfer event messages 403a and 403b, a time marker 404, and a legend display section 405.

[0034] The module display axes 401a to 401d (collectively referred to as the module display axis 401) correspond to the track modules 106a to 106d along which the transport vehicle 101 travels, and each vertical axis (downward arrow) indicates the flow of time passing downward.

[0035] The travel displays 402a and 402b (collectively referred to as travel displays 402) indicate the state in which the transporting vehicles 101a and 101b are staying at a specific track module 106, and are illustrated by corresponding the stay time on the module display axis corresponding to the track module 106 at which the transporting vehicle 101 is staying. In order to distinguish the travel displays 402 for each transporting vehicle 101, they may be illustrated in a shading manner as shown in FIG. 4, or may be illustrated by coloring the vertical axis of the module display axis 401. In addition, the legend case display section 405 indicates the display manner distinction of the travel displays for each transporting vehicle.

[0036] The transfer event messages 403a to 403d (collectively referred to as transfer event messages 403) display a transfer event of a specific transport vehicle 101 by an arrow pointing from a pre-transfer module to a post-transfer module and a transfer event time. In FIG. 4, for example, the transfer event message 403a illustrates that a transfer event from the track module 106a to the track module 106b of the transport vehicle 101a corresponding to the travel display 402a occurred at the time "12:34:56.000". The transfer event message 403 is illustrated at a coordinate position on the module display axis 401 corresponding to the position at the time when the transfer event of the specific transport vehicle 101 occurred. For example, for each specific transport vehicle 101, an arrow is illustrated starting from the pre-transfer track module toward the post-transfer module. Also, the time when the transfer event occurred is included in the corresponding specific transfer event message 403, so that the user can visually know the timing when the transfer event occurred. Note that, in the embodiment of the present invention, the transfer event message is illustrated by an arrow as shown in Fig. 4, but this is not limiting, and any marking such as a solid line, a dotted line, or a dashed line may be used.

[0037] The time marker 404 indicates a reference time for displaying the traveling status display screen 400. For example, the time marker 404 may indicate a trouble occurrence time when displaying a traveling status when a specific trouble such as a collision between the transporting vehicles 101 occurs on the transporting vehicle traveling system 100, or may indicate an event occurrence time associated with specific event information designated by the user 105.

[0038] The legend display section 405 indicates the association between a specific travel display 402 displayed on the travel status display screen 400 and a specific transport vehicle 101 .

[0039] The scroll bar 406 moves the display position of the driving status display screen 400 vertically along the module display axis 401. When the position on the module display axis 401 where the event information that the user 105 wishes to view is shown is far from the reference time indicated by the marker 404, the driving display 402 may be drawn at a position outside the driving status display screen 400. In this case, the user 105 may use the scroll bar 406 to adjust the display position so that the event information that the user wishes to view can be displayed. The scroll bar 406 may also be arranged horizontally to move the display position horizontally on the driving status display screen 400 (not shown). [Explanation of flow according to embodiment]

[0040] Next, using Figure 5, we will explain a series of processes from when the operation terminal 103 acquires an event log related to the traveling status of the transport vehicle 101 from the control server 102 to when it displays the traveling status of the transport vehicle on the display unit equipped with the device itself.

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

[0042] Step S502 is a step in which the extraction unit 202 extracts specific event information from the event log read by the control unit 203 from the storage unit 204 upon receiving notification of multiple or any pieces of information for each of the event identifier to be extracted notified by the input unit 208, the identifier of the specific transport vehicle 101, or the identifier of the specific track module 106. After completing execution of step S502, the operation terminal 103 executes step S600 (details of which will be described separately later) which is an event determination flow.

[0043] In step S503, the generation unit 206 generates a This is a step of generating drawing data for drawing the traveling status display screen 400 based on the time information obtained from the event information extracted by the determination unit 205. The generation unit 206 determines the length of the traveling display 402 related to the transporting vehicle 101 to be drawn on each module display axis 401 and the coordinates on the traveling status display screen 400 based on information such as the time information of the module display axis 401 required for forming the traveling status display screen 400 based on the time information obtained from the event information extracted by the determination unit 205 and the stay time of each track module 106 read from the event log related to the specific transporting vehicle 101. In addition, the generation unit 206 determines the coordinates on the traveling status display screen 400 of a transfer event message for a transfer event to a new track module.

[0044] In step S504, the display unit 207 displays the driving situation display screen 400 based on the display data generated by the generation unit 206 in step S503.

[0045] The operation terminal 103 sequentially executes the processing of steps S501 to S504 described above to display on the display unit 207 a driving status display screen 400 relating to a specific transport vehicle 101, a specific track module 106, or a specific event identifier desired by the user 105.

[0046] Fig. 6 is a flow diagram showing a series of processes in which the event determination unit 205 included in the operation terminal 103 determines whether the transport vehicle 101 will transfer the track module from the event information notified from the extraction unit 202. From here, a series of processes in step S600 in Fig. 5, that is, the series of processes from when the event determination unit 205 included in the operation terminal 103 determines the event information to when the generation unit 206 creates drawing data, will be described with reference to Fig. 6.

[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 whether the transport vehicle 101 has been transferred to a new track module 106 (whether a transfer event has occurred) based on the event log (step S602). More specifically, the event determination unit 205 determines that a "transfer event" indicating that the track module 106 has been moved has occurred when the control server 102 or a specific transport vehicle 101 detects event information specific to transfer recorded in the event log (for example, a communication antenna switching event in the traveling direction of the transport vehicle 101, and a barcode reading event, etc.), or when it is clear that the transport vehicle 101 has transferred to the track module 106 based on the position information of the transport vehicle 101 traveling recorded in the event log. In addition, the transfer event may be detected by recording event information including a specific event identifier determined by the control server 102. If a transfer event occurs in the flow of step S602, step S603 is executed (Yes in step S602), and if a transfer event does not occur, step S605 is executed (No in step S602).

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

[0050] Next, the event determination unit 205 acquires the identifier of the trajectory module 106 before the transfer and the identifier of the trajectory module 106 after the transfer from the event logs before and after the transfer event is detected (step S604). On the other hand, if the event determination unit 205 determines in step S602 that a transfer event has not occurred, the identifier of the track module on which the transport vehicle 101 is traveling is obtained from the event log (step S605).

[0051] Finally, as a result of the judgment in step S602, the information of the track module related to the specific transport vehicle 101 is notified to the generation unit 206, whereby the generation unit 206 determines the coordinates and the length in the module display axis direction for drawing the traveling display 402 related to the traveling situation of the transport vehicle 101, and reflects them in the drawing data (step S606). More specifically, when it is judged in step S602 that a transfer event has occurred, the time when the transfer event occurred and the information of the track module 106 on which the transport vehicle 101 has traveled before and after the time (the track module identifier before transfer and the track module identifier after transfer) are determined, and notified to the generation unit 206. Based on the notified information, the generation unit 206 determines the coordinates and length for drawing the traveling display 402 corresponding to the track module 106 before transfer and the coordinates and length for drawing the traveling display 402 corresponding to the track module 106 after transfer. Next, the generation unit 206 determines the coordinates for arranging a transfer event message including the time and an arrow of the timing when the transfer event occurred on the display screen, and reflects the result of the transfer event in the drawing data of the traveling status display screen 400. On the other hand, if it is determined in step S602 that a transfer event has not occurred, the event determination unit 205 notifies the generation unit 206 of the identifier of the track module 106 on which the specific transport vehicle 101 is traveling, which was acquired in step S605. The generation unit 206 determines the coordinates for drawing the traveling display 402 based on the notification, and reflects the coordinates in the drawing data.

[0052] The present invention can be realized not only as an apparatus, but also as a method in which the processing means constituting the apparatus are steps, as a program for causing a computer to execute those steps, as a computer-readable storage medium such as a CD-ROM on which the program is recorded, or as information, data or signals indicating the program.These programs, information, data and signals may be distributed via a communication network such as the Internet.
