Description

[Technical field]

[0001] The present invention relates to an information display system including a display device that displays information, a control device that controls the display device, and a recording device. [Background technology]

[0002] An example of such an information display system is disclosed in the following Patent Document 1 (JP 2016-52919 A). In the following description of this background art, the reference characters and names in Patent Document 1 will be cited in parentheses.

[0003] The information display system of Patent Document 1 includes a display device (display 128) that displays information, and a recording device (storage 123) that stores position information indicating the position of the transport vehicle (112) and the time when the transport vehicle was located in association with each other. The display device (128) displays a transport vehicle mark (transport vehicle icon 133) indicating the position of the transport vehicle (112) corresponding to a predetermined time on a map (route map 132) of the travel route of the transport vehicle (112).

[0004] In addition, the storage device (123) stores status information indicating the status of the transport vehicle (112) in association with the time when the status information was acquired. The display device (128) is provided with a display area for a status graph (134) that visually shows the change over time of the status information corresponding to a predetermined time, in addition to the display area for the map (132) of the travel route of the transport vehicle (112) and the transport vehicle mark (133).

[0005] In Patent Document 1, the status information indicating the status of the transport vehicle (112) includes the operating mode status of the transport vehicle (112), an abnormality code indicating the type of abnormality, the detection status of multiple luggage sensors provided on the lifting platform (114), information on whether luggage is present on the lifting platform (114), output values ​​of encoders provided corresponding to the front and rear wheels of the cart (113), respectively, the speed obtained from the encoder output values ​​and time information from a timer, and the output voltage value of the battery installed in the transport vehicle (112).

[0006] [Patent Document 1] JP 2016-52919 A Summary of the Invention [Problem to be solved by the invention]

[0007] When a transport vehicle is traveling, it would be useful to know how much vibration was measured on the transport vehicle. For example, if it were possible to know at which location on the travel path of the transport vehicle a large vibration was measured, it would be possible to infer that some abnormality has occurred in that part of the travel path. However, in the technology described in Patent Document 1, information on the vibration of the transport vehicle (112) is not acquired as status information indicating the status of the transport vehicle (112).

[0008] Furthermore, in the technology of Patent Document 1, the status graph (134) only shows the change over time of the status information within a predetermined period, and even if one looks at the status graph (134), it is unclear which part of the status graph (134) showing the change over time of the status information within the predetermined period shows the status at a predetermined time corresponding to the position of the carrier mark (133). In other words, even if one wants to check the status at a specific time among the changes over time of the status information displayed on the status graph (134), it is not easy to know where on the travel route the carrier was traveling at that time.

[0009] Therefore, it is desirable to realize an information display system that allows the relationship between the shape and structure of the vehicle's travel route and vibration to be easily understood. [Means for solving the problem]

[0010] In view of the above, a characteristic configuration of the information display system is an information display system comprising a display device that displays information, a control device that controls the display device, and a recording device, wherein the recording device records transport vehicle driving data, which is data in which position information indicating the position of the transport vehicle and vibration information indicating vibrations measured by the transport vehicle are associated, and route map data, which is data on a map of the driving route traveled by the transport vehicle, and the control device sets a first display area and a second display area on a display screen of the display device, and executes a map display process that displays at least a portion of the map based on the route map data in the first display area, a transport vehicle display process that displays a transport vehicle mark indicating the position of the transport vehicle at the display target time on the map displayed in the first display area by the map display process, a graph display process that displays in the second display area a vibration result graph showing the vibration information at least at the display target time and the times before and after it, and a position mark display process that displays in the second display area a position mark indicating a position on the vibration result graph corresponding to the display target time.

[0011] According to this configuration, the map of the travel route and the position of the transport vehicle on the map at the display target time are displayed in the first display area of ​​the display screen of the display device by the map display process and the transport vehicle display process. In addition, the graph display process and the position mark display process display a vibration result graph showing at least the vibration information at the display target time and before and after the display target time, and a position mark showing the position on the vibration result graph corresponding to the display target time. In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp what kind of vibration was measured when the transport vehicle is at what position on the travel route. Therefore, an information display system that allows the relationship between the shape and structure of the travel route shown on the map and the vibration to be easily grasped can be realized.

[0013] An embodiment of the information display system will be described with reference to the drawings. In this embodiment, an example in which the information display system displays information output from a vibration measuring device 20 mounted on a transport vehicle 3 that transports an article will be described. Therefore, in the following description, first, an example in which the vibration measuring device 20 is mounted on a transport vehicle 3 that transports an article and the vibration measuring device 20 performs vibration measurement will be described. FIG. 1 is a plan view of an article transport facility 200 in which vibration measurement is performed using the vibration measuring device 20. FIG. 2 is a side view of a transport vehicle 3 that mounts the vibration measuring device 20. FIG. 3 is a schematic block diagram showing the configuration of the transport vehicle 3 and the vibration measuring device 20. FIGS. 4 and 5 are explanatory diagrams of the operating state of a guide wheel 17 provided on the transport vehicle 3. In the following description, the direction along the travel path 1 is the travel direction Y, and the direction along the horizontal plane and perpendicular to the travel direction Y is the width direction X. The vertical direction Z is a direction perpendicular to the travel direction Y and the width direction X.

[0014] The article transport facility 200 includes a traveling rail 2 suspended from a ceiling and installed along a travel path 1, and a transport vehicle 3 suspended from the traveling rail 2, traveling on the traveling rail 2 along the travel path 1, and transporting a container W. That is, the transport vehicle 3 described in this embodiment is a so-called ceiling transport vehicle. The transport vehicle 3 transports, for example, a container W such as a FOUP (Front Opening Unified Pod) that contains articles such as wafers that are materials for semiconductor substrates.

[0015] As shown in FIG. 1, the travel path 1 includes, for example, one circular main path 1M, a plurality of circular sub-paths 1S passing through a plurality of processing devices 202, and a maintenance path 1C provided in a maintenance area E2 described later. The travel path 1 is a one-way street. The transport vehicle 3 travels on the travel path 1 from the upstream side of the travel direction Y to the downstream side of the travel direction Y. The travel path 1 also includes a transport area E1, which is an area through which the transport vehicle 3 passes when transporting a container W, and a maintenance area E2, which is an area through which the transport vehicle 3 passes when performing maintenance. In the maintenance area E2, for example, a maintenance lifter 204 is disposed for lowering the transport vehicle 3 suspended from the travel rail 2 to the ground side for maintenance. As shown in FIG. 4 and FIG. 5, the transport vehicle 3 is guided by a pair of travel rails 2.

[0016] Processing equipment 202 is, for example, a semiconductor processing equipment for performing various processes such as exposure processing and etching processing. In this case, the above-mentioned FOUP is transported as a container W in item transport facility 200. Note that the container W and the items contained in the container W may be other objects. For example, transport vehicle 3 may transport a reticle used in an exposure processing of a wafer in the manufacturing process of a semiconductor substrate as the item, and a reticle pod that contains the reticle as the container W. A mounting table 203 is provided in each processing equipment 202.

[0017] As shown in Fig. 2, the transport vehicle 3 includes a traveling mechanism 5 that travels along the travel path 1 while being guided by a traveling rail 2 that is arranged and supported by being suspended from the ceiling along the travel path 1, and a transport vehicle main body 12 that is positioned below the travel rail 2 and supported by being suspended from the traveling mechanism 5. The transport vehicle 3 also includes a holding mechanism 6 that suspends and holds a container W, and a lifting mechanism 7 that raises and lowers the holding mechanism 6. As shown in Fig. 2, the transport vehicle 3 travels with the holding mechanism 6 raised to transport the container W.

[0018] As shown in Figs. 2, 4 and 5, each traveling mechanism 5 is provided with a pair of traveling wheels 15 that are rotationally driven by an electric traveling actuator 35. The traveling actuator 35 is, for example, a motor (travel motor). The traveling wheels 15 roll on a traveling surface formed on each upper surface of the traveling rails 2. Although not shown in detail, the traveling mechanism 5 is provided with a pair of traveling auxiliary wheels 16 that freely rotate around an axis (around a vertical axis) along the vertical direction Z in a state of contact with each inner surface of the pair of traveling rails 2.

[0019] As shown in Figs. 4 and 5, the branching section of the travel path 1 is provided with a guide rail 13 extending in a direction along the travel direction Y of the transport vehicle 3. Although not shown, a similar guide rail 13 is also provided in the merging section of the travel path 1. The guide rail 13 has a pair of guide surfaces 14 (first guide surface 14a, second guide surface 14b). The pair of guide surfaces 14 (first guide surface 14a, second guide surface 14b) are the first guide surface 14a and the second guide surface 14b that face opposite each other in the width direction X perpendicular to the travel direction Y and extend along the travel direction Y. In addition, the transport vehicle 3 is provided with a guide wheel 17 that rotates around a vertical axis (around a vertical axis) along the vertical direction Z. The guide wheel 17 is arranged so that its position can be changed to the right or left of the guide rail 13, which is located in the center between a pair of left and right running rails 2, and rotates in contact with the first guide surface 14a, which is the guide surface 14 on the right side of the guide rail 13, or the second guide surface 14b, which is the guide surface 14 on the left side.

[0020] The vehicle control unit 4 provided in the transport vehicle 3 controls the running mechanism 5 to perform a switching operation to selectively abut the guide wheel 17 against either of the pair of guide surfaces 14 in the branching section and the merging section, as described below.

[0021] FIG. 4 shows an example of the case where the transport vehicle 3 is caused to proceed (in this example, to travel straight) to the right path in the traveling direction Y in the branching section. In this case, the vehicle control unit 4 positions the guide wheel 17 on the side of the first guide surface 14a of the guide rail 13 (on the right side in the traveling direction Y). As a result, the transport vehicle 3 travels in a state where the first guide surface 14a of the guide rail 13 and the guide wheel 17 are in contact with each other. As shown in FIG. 4, when the transport vehicle 3 travels straight through the path on the right side (first side X1 in the width direction) in the branching section, the travel rail 2 on one of the left and right sides (here, the left side) of the pair of traveling rails 2 is interrupted, and the left traveling wheel 15 and the traveling auxiliary wheel 16 are in a state of being derailed. Note that the traveling auxiliary wheel 16 is omitted in FIG. 4 for simplification. However, the guide rail 13 receives the load of the transport vehicle 3 through the guide wheel 17 and guides and supports it, so that the transport vehicle 3 is prevented from falling off the traveling rail 2, and the transport vehicle 3 can travel straight in the branching section.

[0022] FIG. 5 is an example in which the transport vehicle 3 is caused to proceed to a left path in the traveling direction Y in the branching section (branching along a curved path in this example). In this case, the vehicle control unit 4 positions the guide wheel 17 on the side of the second guide surface 14b of the guide rail 13 (on the left side in the traveling direction Y). As a result, the transport vehicle 3 is guided in a state in which the second guide surface 14b of the guide rail 13 and the guide wheel 17 are in contact with each other. As shown in FIG. 5, when the transport vehicle 3 branches through a path on the left side (second side X2 in the width direction) in the branching section, the travel rail 2 on one of the left and right sides (here, the right side) of the pair of travel rails 2 is interrupted, and the right travel wheel 15 and the travel auxiliary wheel 16 are in a state of derailment. However, the guide rail 13 receives the load of the transport vehicle 3 through the guide wheel 17 and guides and supports it, so that the transport vehicle 3 is prevented from falling off the travel rail 2, and the transport vehicle 3 can branch and travel in the branching section.

[0023] As shown in FIG. 3, the transport vehicle 3 includes a position detection sensor 8, a speed sensor 9, an object detection sensor 10, and a communication unit 11 in addition to the above-mentioned components.

[0024] The vehicle control unit 4 controls the operation of the transport vehicle 3. For example, the vehicle control unit 4 can wirelessly communicate information with an equipment control unit H that manages the entire article transport equipment 200 via the communication unit 11. Then, based on a transport command from the equipment control unit H, the vehicle control unit 4 autonomously controls the transport vehicle 3 to travel, transport the container W between different mounting tables 203, stops the transport vehicle 3 above a designated mounting table 203, and moves the holding mechanism 6 up and down to transfer the container W.

[0025] The position detection sensor 8 is used to detect the position of the transport vehicle 3. For example, as shown in FIG. 3, a position index B indicating the position on the travel route 1 is arranged along the travel route 1. The position index B can be, for example, a one-dimensional or two-dimensional barcode or a marker with numbers or letters. The position detection sensor 8 can be a barcode reader, an image recognition device, or a character recognition device that recognizes numbers and letters. The position detection sensor 8 can derive the travel distance of the transport vehicle 3 using a sensor that detects the rotation angle of the axle (not shown) of the running wheel 15. The position detection sensor 8 can detect the current position of the transport vehicle 3 on the travel route 1 based on the travel distance of the transport vehicle 3 after detecting the position index B. The position information detected by the position detection sensor 8 is transmitted to the vehicle control unit 4. In this way, the transport vehicle 3 can detect its position on the travel route 1 using multiple position indexes B. Furthermore, the transportation vehicle 3 successively transmits detected position information to the equipment control unit H, and the equipment control unit H can transmit to the transportation vehicle 3 a transportation command generated based on the position information.

[0026] The speed sensor 9 is used to detect the traveling speed of the transport vehicle 3. The speed sensor 9 can be realized by using, for example, a sensor that detects the rotation angle of the axle (not shown) of the traveling wheel 15. In that case, the speed sensor 9 derives the rotation speed of the axle based on the rotation angle of the axle (not shown) of the traveling wheel 15, and can derive the traveling speed of the transport vehicle 3 based on the rotation speed. Then, the speed sensor 9 may transmit the derived traveling speed to the vehicle control unit 4. Alternatively, the speed sensor 9 may sequentially transmit the measured rotation angle of the axle (not shown) of the traveling wheel 15 to the vehicle control unit 4, and the vehicle control unit 4 may derive the traveling speed of the transport vehicle 3 based on the value of the rotation angle.

[0027] The object detection sensor 10 is used to detect objects that may be obstacles to the traveling transport vehicle 3. For example, a plurality of transport vehicles 3 are present on the travel route 1 and travel simultaneously. Therefore, in order to prevent collisions with other transport vehicles 3, the transport vehicle 3 is provided with an object detection sensor 10 that detects objects that exist within a set area ahead in the travel direction Y.

[0028] 6 and 7 are diagrams for explaining the detection area 18 of the object detection sensor 10 of the transport vehicle 3. As shown in Fig. 6, when the front of the travel direction Y of the transport vehicle 3 is a straight section, the detection area 18 set ahead of the travel direction Y of the transport vehicle 3 is shaped to extend longer along the travel direction Y than the width direction X. On the other hand, as shown in Fig. 7, when the front of the travel direction Y of the transport vehicle 3 is a curved section, the detection area 18 set ahead of the travel direction Y of the transport vehicle 3 is shaped to extend longer along the width direction X than the travel direction Y in accordance with the curved travel route 1.

[0029] Next, the vibration measuring device 20 mounted on the transport vehicle 3 will be described. As shown in FIG. 3, the vibration measuring device 20 includes a vibration measuring unit 21 for measuring vibration, a position information acquiring unit 22 for acquiring position information indicating the position of the transport vehicle 3, a state information acquiring unit 23 for acquiring transport vehicle state information indicating the state of the transport vehicle 3, a recording unit 24 for recording the measurement result by the vibration measuring unit 21, the transport vehicle state information, and the position information in association with each other, and an output unit 25 for outputting the information recorded in the recording unit 24. The vibration measuring device 20 includes an information communication function, an information processing function, an information storage function, and the like, and may realize the functions of the vibration measuring unit 21, the position information acquiring unit 22, the state information acquiring unit 23, the recording unit 24, and the output unit 25 by using at least some of these functions as described later. The vibration measuring device 20 may be realized by a single device equipped with these functions, or may be realized by a plurality of devices equipped with these functions.

[0030] The vibration measuring unit 21 can be realized by using a sensor capable of measuring physical quantities representing vibrations such as vibration amplitude, frequency, acceleration, etc. The vibration measuring unit 21 may also be configured to be capable of measuring vibrations in three mutually orthogonal directions, for example, the X direction, the Y direction, and the Z direction. Alternatively, the vibration measuring unit 21 may be configured to be capable of measuring vibrations in two or one of the X direction, the Y direction, and the Z direction. The vibration measuring unit 21 may acquire time information about the time when the measurement result was acquired together with the vibration measurement result.

[0031] The position information acquiring unit 22 acquires position information indicating the position of the transport vehicle 3. For example, the position information acquiring unit 22 acquires position information indicating the position of the transport vehicle 3 detected by the position detection sensor 8 of the transport vehicle 3, using an information communication function of the vibration measuring device 20. The position information acquiring unit 22 may acquire time information about the time when the position information was detected together with the position information.

[0032] The status information acquiring unit 23 acquires vehicle status information indicating the status of the vehicle 3. For example, the status information acquiring unit 23 acquires the vehicle status information measured by the vehicle 3 by utilizing an information communication function provided in the vibration measuring device 20. The status information acquiring unit 23 may acquire time information about the time when the vehicle status information was measured together with the vehicle status information.

[0033] The transport vehicle status information includes at least one of the travel speed of the transport vehicle 3, the acceleration state of the transport vehicle 3, the operating state of the operating mechanism equipped in the transport vehicle 3, and the detection state of the sensor equipped in the transport vehicle 3 (such as the object detection sensor 10, for example).

[0034] The travel speed of the transport vehicle 3 is a value measured by the speed sensor 9 of the transport vehicle 3. The acceleration state of the transport vehicle 3 (i.e., acceleration indicating an accelerating state, a decelerating state, a constant speed state, etc.) can be determined by calculating the change in the travel speed measured by the speed sensor 9 of the transport vehicle 3. The vehicle control unit 4 of the transport vehicle 3 may calculate the acceleration state of the transport vehicle 3, and the state information acquisition unit 23 of the vibration measuring device 20 may acquire the calculated acceleration state. Alternatively, the state information acquisition unit 23 of the vibration measuring device 20 may calculate the acceleration state from the acquired travel speed of the transport vehicle 3 using the arithmetic processing function of the vibration measuring device 20. For example, it is considered that the vibration of the transport vehicle 3 becomes relatively large when the transport vehicle 3 is accelerating or decelerating, and that the vibration of the transport vehicle 3 becomes relatively small when the transport vehicle 3 is traveling at a constant speed.

[0035] The operating state of the operating mechanism of the transport vehicle 3 is information on the operating state of the operating mechanisms of the transport vehicle 3, such as the travel mechanism 5, the holding mechanism 6, and the lifting mechanism 7. For example, the transport vehicle 3 is provided with the guide wheel 17 shown in FIG. 4 and FIG. 5 as a part of the travel mechanism 5, and the operation of the guide wheel 17 is controlled by the vehicle control unit 4. The state information acquisition unit 23 can acquire information indicating whether the guide wheel 17 is located on the right side or the left side in the travel direction Y from the vehicle control unit 4 of the transport vehicle 3. The operating state is not limited to the state of the guide wheel 17 (i.e., the travel mechanism 5). For example, it may be the operating state of the lifting mechanism 7, the operating state of the holding mechanism 6, etc. For example, when the guide wheel 17 of the travel mechanism 5 operates (i.e., when the position of the guide wheel 17 is switched between left and right), the vibration of the transport vehicle 3 is considered to be relatively large.

[0036] The detection state of the object detection sensor 10 provided in the transport vehicle 3 is, for example, information about the shape of the detection area 18 of the object detection sensor 10 shown in Figs. 6 and 7, information about whether an object is detected, and the like. The state of the detection area 18 of the object detection sensor 10 of the transport vehicle 3 is controlled by the vehicle control unit 4. Information about whether the object detection sensor 10 is detecting an object is transmitted to the vehicle control unit 4. The state information acquisition unit 23 can acquire information about the detection state of the object detection sensor 10 of the transport vehicle 3 from the vehicle control unit 4 of the transport vehicle 3. For example, when the object detection sensor 10 detects an object, it is considered that the vibration of the transport vehicle 3 becomes relatively large due to reasons such as the deceleration of the transport vehicle 3.

[0037] As described above, the status information acquiring unit 23 can acquire, as the vehicle status information, information indicating the behavior of the vehicle 3 that may affect the vibration measured by the vibration measuring unit 21. Therefore, by referring to such vehicle status information, the user can easily analyze whether or not the vibration is strongly affected by the status of the vehicle 3.

[0038] The recording unit 24 records the measurement results (vibration information) by the vibration measuring unit 21, the transport vehicle state information, and the position information in a mutually associated manner. The recording unit 24 can be realized by utilizing the information storage function of the vibration measuring device 20. For example, when the measurement results by the vibration measuring unit 21, the transport vehicle state information, and the position information are all associated with time information as described above, the recording unit 24 can record the measurement results by the vibration measuring unit 21 at the same time or within a predetermined time range, the transport vehicle state information, and the position information in a mutually associated manner. Note that, when the information is not associated with time information, the recording unit 24 may record the measurement results by the vibration measuring unit 21, the transport vehicle state information, and the position information recorded simultaneously or within a predetermined time period in a mutually associated manner as one data set.

[0039] The vibration information may be a physical quantity representing the vibration such as the amplitude, frequency, acceleration, etc. of the vibration measured by the vibration measuring unit 21, or may be a value calculated from these. For example, the vibration information may be an effective value (RMS: root mean square) calculated from the vibration waveform.

[0040] In this way, the recording unit 24 can record the transport vehicle travel data in which at least the position information indicating the position of the transport vehicle 3 and the vibration information indicating the vibration measured by the transport vehicle 3 are associated with each other, or the transport vehicle travel data which is data in which at least the position information indicating the position of the transport vehicle 3, the vibration information indicating the vibration measured by the transport vehicle 3, and the transport vehicle status information indicating the status of the transport vehicle 3 are associated with each other. The position information, the vibration information, and the transport vehicle status information included in the transport vehicle travel data may be associated with time information. In addition, the recording unit 24 can record information on the positions that the transport vehicle 3 has passed during its travel as route map data which is data on the map of the travel route 1 that the transport vehicle 3 has traveled. The information on the positions that the transport vehicle 3 has passed during its travel may be associated with time information.

[0041] The output unit 25 outputs the information recorded in the recording unit 24. For example, the output unit 25 can use an information communication function of the vibration measuring device 20 to output the information recorded in the recording unit 24 to another device that can communicate with the vibration measuring device 20. Note that the output unit 25 not only outputs information in a form to be transmitted to another device, but may also display and output information to the display device 41, print information on paper, output information to a portable storage device, and the like.

[0042] As described above, by using the vibration measuring device 20 of this embodiment, it is possible to obtain information indicating the vibration measured at each position on the travel route 1 along which the transport vehicle 3 has traveled and the state of the transport vehicle 3 at that position. As a result, a user who receives the output of such information can properly grasp information such as at which position on the travel route 1 of the transport vehicle 3 the vibration becomes large and in what state the transport vehicle 3 is at that time. In other words, the vibration measuring device 20 of this embodiment can output information for properly analyzing the cause of the measured vibration.

[0043] Next, the information display system will be described. 8 is a diagram for explaining the configuration of an information display system. As shown in the figure, the information display system includes a display device 41 that displays information, a control device 40 that controls the display device 41, a recording device 45, and an input receiving unit 56. The information display system can be realized using one or more computer devices that include an information display function (i.e., the display device 41), an information communication function, an information calculation function (i.e., the control device 40), an information storage function (i.e., the recording device 45), and an information input receiving function such as a keyboard or a mouse (i.e., the input receiving unit 56).

[0044] The recording device 45 records the vehicle travel data, which is data in which position information indicating the position of the vehicle 3 is associated with vibration information indicating vibrations measured by the vehicle 3, and the route map data, which is data on the map of the travel route 1 traveled by the vehicle 3 (i.e., information on the positions the vehicle 3 passed during its travel). In other words, the vehicle travel data and the route map data are linked by the position of the vehicle 3 at each point in time during its travel. Therefore, if the position of the vehicle 3 at a specific point in time is specified, the vibration information at that position is identified, and it is also identified which part of the map of the travel route 1 corresponds to that position.

[0045] The transport vehicle travel data and the route map data recorded in the recording device 45 are constructed using data output from the output unit 25 of the vibration measuring device 20. For example, when a computer device realizing the information display system and the vibration measuring device 20 are capable of communicating with each other, the information included in the transport vehicle travel data and the route map data may be output from the output unit 25 of the vibration measuring device 20 to the computer device realizing the information display system. Alternatively, the information included in the transport vehicle travel data and the route map data may be output from the output unit 25 of the vibration measuring device 20 to a portable storage device, and then the portable storage device may be connected to the computer device realizing the information display system to read out the stored information, thereby recording the information included in the transport vehicle travel data and the route map data in the recording device 45.

[0046] The control device 40 sets a first display area 43 and a second display area 44 on a display screen 42 of a display device 41, and executes a map display process, a carrier display process, a graph display process, and a position mark display process, which will be described later.

[0047] The map display process is a process of displaying at least a part of a map based on the route map data in the first display area 43. In the example shown in Fig. 8, a travel route mark 46 corresponding to the travel route 1 is displayed. For example, the control device 40 can display the travel route mark 46 by connecting positions that the transport vehicle 3 has passed during its travel with a line. Alternatively, when map information of the travel route 1 is already available, for example, when the travel rail 2 has been laid, the control device 40 may display the travel route map with the travel route mark 46.

[0048] The transportation vehicle display process is a process of displaying a transportation vehicle mark 47 indicating the position of the transportation vehicle 3 at a display target time on the map (travel route mark 46) displayed in the first display area 43 by the map display process. In the example shown in Fig. 8, the control device 40 displays the transportation vehicle mark 47 at a position corresponding to the position of the transportation vehicle 3 at a specific time (i.e., the display target time) on the travel route map displayed by the travel route mark 46 based on route map data which is map data of the travel route 1 traveled by the transportation vehicle 3 (i.e., information on the positions passed by the transportation vehicle 3 during its travel). The shape, pattern, etc. of the transportation vehicle mark 47 can be set appropriately.

[0049] The graph display process is a process of displaying a vibration result graph 48 showing vibration information at least at a display target time point and the times before and after that in the second display area 44. In the example shown in Fig. 8, the control device 40 displays a vibration result graph 48 which graphs the transition of vibration information at a specific time point (i.e., a display target time point) and the times before and after that, based on the carrier travel data which is data in which position information showing the position of the carrier 3 is associated with vibration information showing vibrations measured by the carrier 3.

[0050] The position mark display process is a process for displaying a position mark 49 indicating a position corresponding to a display target time point on the vibration result graph 48 in the second display area 44. In the example shown in Fig. 8, the control device 40 displays a dashed line 49a indicating the display target time point and an arrow 49b pointing to the dashed line 49a as the position mark 49. The shape, pattern, etc. of the position mark 49 can be set as appropriate.

[0051] In this way, the map of the travel route 1 and the position of the transport vehicle 3 on the map at the display target time are displayed in the first display area 43 in the display screen 42 of the display device 41 by the map display process and the transport vehicle display process. In addition, the graph display process and the position mark display process display the vibration result graph 48 showing at least the vibration information at the display target time and before and after the display target time, and the position mark 49 showing the position on the vibration result graph 48 corresponding to the display target time. In other words, a person who sees the display screen 42 including the first display area 43 and the second display area 44 can visually and easily grasp what kind of vibration was measured when the transport vehicle 3 was at what position on the travel route 1. Therefore, an information display system that can easily grasp the relationship between the shape and structure of the travel route 1 shown on the map and the vibration can be realized.

[0052] The transportation vehicle travel data may further include travel speed information indicating the travel speed of the transportation vehicle 3, and the travel speed information may be data associated with the position information and the vibration information. Then, the control device 40 may execute a reproduction display process in which the transportation vehicle mark 47 is moved relative to the map at a speed corresponding to the travel speed of the transportation vehicle 3 based on the transportation vehicle travel data in the transportation vehicle display process, and the position mark 49 is moved relative to the vibration result graph 48 at a speed corresponding to the movement speed of the transportation vehicle mark 47 in the position mark display process. Alternatively, the control device 40 may move the transportation vehicle mark 47 relative to the map at a constant speed that is unrelated to the travel speed of the transportation vehicle 3.

[0053] Although not shown, the control device 40 may display playback control buttons such as a playback start button and a playback stop button on the display screen 42, and perform playback display processing in response to an operation input (i.e., an instruction related to playback display such as playback start and playback stop) performed by the user using an input receiving unit 56 such as a mouse. Alternatively, the control device 40 may automatically perform playback display processing even if the user does not perform an operation input to the playback start button.

[0054] By executing such map display processing, carrier display processing, and reproduction display processing, a map of the travel route 1 and a carrier mark 47 indicating the position of the carrier 3 on the map at the display target time are displayed in a first display area 43 in a display screen 42 of the display device 41, and further, the carrier mark 47 moves relatively to the map at a speed corresponding to the travel speed of the carrier 3 based on the carrier vehicle travel data. Also, by executing the graph display processing, position mark display processing, and reproduction display processing, a vibration result graph 48 indicating vibration information at least at the display target time and before and after that, and a position mark 49 indicating a position on the vibration result graph 48 corresponding to the display target time are displayed in a second display area 44 in the display screen 42 of the display device 41, and further, the position mark 49 moves relatively to the vibration result graph 48 at a speed corresponding to the travel speed of the carrier 3 based on the carrier vehicle travel data. In other words, a person looking at the display screen 42 including the first display area 43 and the second display area 44 can easily visually grasp at what position the transport vehicle 3 is located on the travel route 1, at what speed the transport vehicle 3 is moving, and at what values ​​the vibration has changed.

[0055] For example, in the first display area 43, the control device 40 can perform a playback display process such as fixing the display position of the transport vehicle mark 47 and moving the driving route mark 46 indicating the driving route map, a playback display process such as fixing the driving route mark 46 indicating the driving route map and moving the display position of the transport vehicle mark 47, and a playback display process such as moving both the display position of the transport vehicle mark 47 and the driving route mark 46 indicating the driving route map.

[0056] In addition, in the second display area 44, the control device 40 can perform a playback display process such as fixing the display position of the position mark 49 indicating the time to be displayed and moving the vibration result graph 48, a playback display process such as fixing the display of the vibration result graph 48 and moving the display position of the position mark 49 indicating the time to be displayed, and a playback display process such as moving both the display position of the position mark 49 indicating the time to be displayed and the vibration result graph 48.

[0057] The control device 40 can change the information displayed in the first display area 43 and the second display area 44 in response to an instruction received from a user via, for example, the input receiving unit 56. Below, several examples of display screens in the first display area 43 and the second display area 44 will be described.

[0058] 9 is a diagram showing an example of a display screen of the display device 41. In this example, the transport vehicle running data further includes transport vehicle status information indicating the status of the transport vehicle 3, and the transport vehicle status information is data associated with position information and vibration information. In the graph display process, the control device 40 displays a transport vehicle status graph 50 indicating the transport vehicle status information at least at the display target time point and the times before and after the display target time point together with a vibration result graph 48 in the second display area 44, and in the position mark display process, displays a position on the transport vehicle status graph 50 corresponding to the display target time point by a position mark 49 in the second display area 44.

[0059] In the example shown in FIG. 9, the information on the travel speed of the transport vehicle 3 is set as the transport vehicle status information. In the graph display process, the control device 40 displays a vibration result graph 48 in which the transition of vibration information at a specific time point (i.e., the display target time point) and the time before and after the specific time point are graphed, and a transport vehicle status graph 50 in which the transition of the travel speed is graphed, based on the transport vehicle travel data in which the information on the travel speed of the transport vehicle 3 (transport vehicle status information) is associated with the position information and the vibration information. In this way, a person who sees the display screen 42 including the first display area 43 and the second display area 44 can visually and easily grasp what vibration was measured and what state the transport vehicle 3 was in when the transport vehicle 3 was at what position on the travel route 1. As a result, there is an advantage that it is easy to grasp the relationship between the shape and structure of the travel route 1 shown on the map, the vibration, and the state of the transport vehicle 3.

[0060] 9, the vibration result graph 48 and the transport vehicle status graph 50 are displayed in one second display area 44, but for example, a plurality of second display areas 44 may be provided on the display screen 42, and the vibration result graph 48 and the transport vehicle status graph 50 may be displayed in each second display area 44. In that case, the position mark 49 may also be displayed in each second display area 44.

[0061] In addition, the control device 40 executes a transport vehicle status display process to display a transport vehicle status mark 51 indicating transport vehicle status information on the map displayed by the map display process, corresponding to the transport vehicle mark 47 displayed by the transport vehicle display process.

[0062] In the example shown in FIG. 9, the information on the operation state of the guide wheel 17 (i.e., whether the guide wheel 17 is located on the right side or the left side in the traveling direction Y) is the transport vehicle state information. Then, in the transport vehicle state display process, the control device 40 displays the transport vehicle state mark 51 indicating the operation state of the guide wheel 17 in correspondence with the transport vehicle mark 47 displayed in the transport vehicle display process on the map displayed in the map display process based on the transport vehicle travel data in which the information on the operation state of the guide wheel 17 (transport vehicle state information) is data associated with the position information and the vibration information. In the illustrated example, the state in which the guide wheel 17 is located on the left side in the traveling direction Y is displayed. In this way, a person who sees the display screen 42 including the first display area 43 and the second display area 44 can visually and easily grasp what vibration was measured and what state the guide wheel 17 of the transport vehicle 3 was in when the transport vehicle 3 was in the traveling route 1.

[0063] 10 and 11 are diagrams showing examples of the display screen of the display device 41. In this example, the transport vehicle running data further includes transport vehicle status information indicating the status of the transport vehicle 3, and the transport vehicle status information is data associated with the position information and the vibration information. Then, the control device 40 further executes a transport vehicle status display process to display a transport vehicle status mark 51 indicating the transport vehicle status information on the map displayed by the map display process, in correspondence with the transport vehicle mark 47 displayed by the transport vehicle display process.

[0064] In the example shown in FIG. 10 and FIG. 11, information on the travel speed of the transport vehicle 3 is used as the transport vehicle status information. Then, in the transport vehicle status display process, the control device 40 displays a transport vehicle status mark 51 indicating the travel speed of the transport vehicle 3 in correspondence with the transport vehicle mark 47 displayed by the transport vehicle display process on the map displayed by the map display process based on data in which the information on the travel speed of the transport vehicle 3 (transport vehicle status information) is associated with the position information and the vibration information. For example, in FIG. 10 and FIG. 11, the travel speed of the transport vehicle 3 is displayed as the transport vehicle status information by a dashed arrow as the transport vehicle status mark 51. In this case, the longer the dashed arrow, the faster the travel speed is indicated. In other words, the dashed arrow as the transport vehicle status mark 51 shown in FIG. 10 is displayed in a longer shape than the dashed arrow as the transport vehicle status mark 51 shown in FIG. 11, so it can be seen that the travel speed of the transport vehicle 3 at the time shown in FIG. 10 is faster. In this way, a person looking at the display screen 42 including the first display area 43 and the second display area 44 can easily visually understand what vibrations were measured and what the speed of the transport vehicle 3 was when the transport vehicle 3 was at a particular position on the travel route 1.

[0065] FIG. 12 is a diagram showing an example of a display screen of the display device 41. In this example, the transport vehicle travel data further includes detection area information indicating the state of the detection area 18 of the object detection sensor 10 provided in the transport vehicle 3, and the detection area information is data associated with the position information and the vibration information. Then, the control device 40 further executes a detection area display process to display a detection area mark 53 indicating the state of the detection area 18 at the time of display, on the map displayed by the map display process, corresponding to the transport vehicle mark 47 displayed by the transport vehicle display process, based on the transport vehicle travel data. For example, in FIG. 12, the horizontal shape of the detection area 18 is displayed as the transport vehicle state information in a dashed line shape as the detection area mark 53. The shape of the detection area mark 53 shown in FIG. 12 is the same as the shape of the detection area 18 shown in FIG. 7. In this way, a person who sees the display screen 42 including the first display area 43 and the second display area 44 can visually and easily grasp what vibration was measured and what state the detection area 18 of the object detection sensor 10 of the transport vehicle 3 was in when the transport vehicle 3 was at what position on the travel route 1. The shape, pattern, etc. of the detection area mark 53 can be set appropriately.

[0066] FIG. 13 is a diagram showing an example of a display screen of the display device 41. In this example, the control device 40 further executes a route shape display process to display, in the second display area 44, a route shape display 52 showing the characteristics of the shape of the travel route 1 traveled by the carrier 3 in association with the position where the vibration displayed in the vibration result graph 48 was measured. In the example shown in FIG. 13, the pattern of a part of the second display area 44 (a part corresponding to a curved section of the travel route 1) is different from the rest. Then, the route shape display 52 "180° inner wheel R500" is displayed, which means that the curved section is a 180° rotation with a curvature radius of 500 mm on the inner wheel side of the travel route 1. In this way, a person who sees the display screen 42 including the second display area 44 can visually and easily grasp the relationship between the shape of the travel route 1 and the vibration.

[0067] 14 is a diagram showing an example of a display screen of the display device 41. In this example, the control device 40 executes a vibration point mark display process for displaying on a map a vibration point mark 54 indicating a point on the travel route 1 where the vibration value indicated in the vibration information exceeds a predetermined judgment threshold value. A mouse pointer 55 is also displayed in the first display area 43. In this way, a person who sees the first display area 43 can easily understand at which point on the travel route 1 a large vibration is occurring. In addition, the first display area 43 shown in FIG. 14 also displays a transport vehicle state mark 51 indicating the travel speed of the transport vehicle 3.

[0068] The control device 40 can further execute an operation reception process for receiving a selection operation for the vibration point mark 54 displayed by the vibration point mark display process. For example, the user can operate an input reception unit 56 such as a mouse to perform a selection input for a specific vibration point mark 54 with a mouse pointer 55. When the control device 40 receives a selection operation for the vibration point mark 54 by the operation reception process, the control device 40 starts a playback display process from a point upstream of the point indicated by the vibration point mark 54, as shown in FIG.

[0069] In this way, when the playback display process accepts an operation on the vibration point mark 54, playback display is performed from a point upstream of the point indicated by the vibration point mark 54, so that information that makes it easy to understand the shape and structure of the travel path 1 before and after a point on the travel path 1 where the vibration of the transport vehicle 3 is relatively large, and the travel speed of the transport vehicle 3, can be displayed on the display device 41.

[0070] Other embodiments Next, other embodiments of the information display system will be described.

[0071] (1) In the above embodiment, the transport vehicle 3 is an overhead transport vehicle. However, the transport vehicle 3 is not limited to such a configuration, and may be, for example, an automatic guided vehicle (AGV), a sorting transfer vehicle (STV), a stacker crane, or an autonomous mobile robot (AMR).

[0072] (2) In the above embodiment, an example has been described in which the position detection sensor 8 detects the position of the transport vehicle 3 based on the position index B indicating the position on the travel route 1, but the position detection sensor 8 may detect the position of the transport vehicle 3 by other means. For example, the position detection sensor 8 may detect the position of the transport vehicle 3 by receiving a signal from a GNSS satellite that constitutes the GNSS (Global Navigation Satellite System).

[0073] (3) In the above embodiment, the content of the transport vehicle status information can be changed as appropriate. For example, the information may include information on the detection state of various sensors equipped in the transport vehicle 3. Examples of the various sensors equipped in the transport vehicle 3 include a sensor that detects the operating state of the holding mechanism 6 that holds the container W, a sensor that detects the operating state of the lifting mechanism 7 that lifts and lowers the holding mechanism 6, and the like.

[0074] (4) In the above embodiment, an example has been described in which the first display area 43 and the second display area 44 are clearly separated on the display screen 42, but how the first display area 43 and the second display area 44 are displayed on the display screen 42 can be set as appropriate. For example, the first display area 43 and the second display area 44 may be displayed so as to partially overlap on the display screen 42. Also, a display area other than the first display area 43 and the second display area 44 may be displayed on the display screen 42.

[0075] (5) In the above embodiment, the control device 40 may, in response to instructions given by the user by operating the input receiving unit 56, zoom in and out on the map of the driving route 1 displayed in the first display area 43, and move it up, down, left, and right, and may also zoom in and out on a graph, etc. displayed in the second display area 44, and move it up, down, left, and right.

[0076] (6) In the above embodiment, if the transition of the information to be displayed in the second display area 44 can be known, the horizontal axis of the graph displayed in the second display area 44 can be set appropriately. For example, the horizontal axis may be the total travel distance of the transport vehicle 3, the order in which the information was recorded, or the like.

[0077] (7) In the above embodiment, the contents of the reproduction display process can be changed as appropriate. For example, when the user instructs to select and move the transportation vehicle mark 47 in the first display area 43 using the input receiving unit 56 such as a mouse (i.e., dragging the transportation vehicle mark 47 with the mouse), the control device 40 may perform a reproduction display process in which the control device 40 moves the transportation vehicle mark 47 relative to the map (travel route mark 46) in response to the instruction and accordingly moves the position mark 49 in the second display area 44 relatively to the vibration result graph 48.

[0078] (8) In the above embodiment, the vehicle status mark 51 indicating the traveling speed of the vehicle 3 is displayed as a dashed arrow as shown in Fig. 10 and Fig. 11, but the display mode of the vehicle status mark 51 can be changed as appropriate. For example, a numerical value (i.e., text information) indicating the traveling speed of the vehicle 3 may be displayed as the vehicle status mark 51.

[0079] (9) The configurations disclosed in the above-described embodiments can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. As for other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications can be made as appropriate within the scope of the present disclosure.

[0080] [Summary of the above embodiment] The information display system described above will now be outlined.

[0082] According to this configuration, the map of the travel route and the position of the transport vehicle on the map at the display target time are displayed in the first display area of ​​the display screen of the display device by the map display process and the transport vehicle display process. In addition, the graph display process and the position mark display process display a vibration result graph showing at least the vibration information at the display target time and before and after the display target time, and a position mark showing the position on the vibration result graph corresponding to the display target time. In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp what kind of vibration was measured when the transport vehicle is at what position on the travel route. Therefore, an information display system that allows the relationship between the shape and structure of the travel route shown on the map and the vibration to be easily grasped can be realized.

[0083] Here, the transport vehicle driving data further includes transport vehicle status information indicating the status of the transport vehicle, and the transport vehicle status information is data associated with the position information and the vibration information, and in the graph display process, the control device preferably displays a transport vehicle status graph indicating the transport vehicle status information at least at the display target time and the times before and after it in the second display area together with the vibration result graph, and in the position mark display process, displays a position on the transport vehicle status graph corresponding to the display target time in the second display area using the position mark.

[0084] According to this configuration, the graph display process and the position mark display process display a vehicle status graph showing vehicle status information at least at the display target time and the time before and after the display target time in the second display area of ​​the display screen of the display device, together with a vibration result graph and a position mark showing a position on the vibration result graph corresponding to the display target time. In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp what vibration was measured and what state the vehicle was in when the vehicle was at a certain position on the travel route. As a result, there is an advantage that it is easy to grasp the relationship between the shape and structure of the travel route shown on the map, the vibration, and the state of the vehicle.

[0085] In addition, it is preferable that the transport vehicle driving data further includes transport vehicle status information indicating the status of the transport vehicle, and the transport vehicle status information is data associated with the position information and the vibration information, and the control device further executes a transport vehicle status display process to display a transport vehicle status mark indicating the transport vehicle status information on the map displayed by the map display process, in correspondence with the transport vehicle mark displayed by the transport vehicle display process.

In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp what vibration was measured and what status the vehicle was in when the vehicle was at what position on the travel route.

[0087] It is also preferable that the transport vehicle status information includes at least one of the travel speed of the transport vehicle, the acceleration state of the transport vehicle, the operating state of a travel mechanism equipped in the transport vehicle, and the detection state of a sensor equipped in the transport vehicle.

[0088] According to this configuration, the graph display process and the position mark display process display a vehicle status graph showing vehicle status information including at least one of the travel speed of the vehicle, the acceleration state of the vehicle, the operating state of the travel mechanism of the vehicle, and the detection state of the sensor of the vehicle at the display target time and the time before and after the display target time, together with a vibration result graph and a position mark showing a position on the vibration result graph corresponding to the display target time. Here, the travel speed of the vehicle, the acceleration state of the vehicle, the operating state of the travel mechanism of the vehicle, and the detection state of the sensor of the vehicle as the vehicle status information showing the state of the vehicle may affect the vibration measured by the vehicle. Therefore, a person who sees the display screen including the second display area can visually easily grasp whether the cause of the vibration of the vehicle is the state of the vehicle.

[0089] In addition, it is preferable that the control device further executes a route shape display process to display in the second display area a route shape display indicating characteristics of the shape of the travel route traveled by the transport vehicle, in correspondence with the position where the vibration was measured, which is displayed in the vibration result graph.

[0090] According to this configuration, a person viewing the display screen including the second display area can visually and easily grasp the relationship between the shape of the travel route and the vibration.

In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp what kind of vibration was measured and what the state of the detection area of ​​the object detection sensor of the transport vehicle was when the transport vehicle was at what position on the travel route.

[0093] In addition, it is preferable that the transport vehicle driving data further includes driving speed information indicating the driving speed of the transport vehicle, and the driving speed information is data associated with the position information and the vibration information, and the control device executes a playback display process in which, in the transport vehicle display process, the transport vehicle mark is moved relative to the map at a speed corresponding to the driving speed of the transport vehicle based on the transport vehicle driving data, and, in the position mark display process, the position mark is moved relative to the vibration result graph at a speed corresponding to the moving speed of the transport vehicle mark.

[0094] According to this configuration, the map display process, the carrier display process, and the playback display process display a map of the travel route and a carrier mark indicating the position of the carrier on the map at the display target time in the first display area of ​​the display screen of the display device, and the carrier mark moves relatively to the map at a speed corresponding to the travel speed of the carrier based on the carrier travel data. Also, the graph display process, the position mark display process, and the playback display process display a vibration result graph indicating vibration information at least at the display target time and before and after the display target time, and a position mark indicating a position on the vibration result graph corresponding to the display target time, and the position mark moves relatively to the vibration result graph at a speed corresponding to the travel speed of the carrier based on the carrier travel data. In other words, a person who sees the display screen including the first display area and the second display area can visually and easily grasp at what position the carrier is located on the travel route, at what speed the carrier is moving, and at what value the vibration is changing.

[0095] In addition, the control device further executes a vibration point mark display process for displaying on the map a vibration point mark indicating a point on the driving route where the vibration value indicated in the vibration information exceeded a predetermined judgment threshold, and an operation reception process for receiving a selection operation on the vibration point mark displayed by the vibration point mark display process, and when the selection operation on the vibration point mark is received by the operation reception process, it is preferable that the control device executes the playback display process from a point upstream of the point indicated by the vibration point mark.

[0096] According to this configuration, the vibration point mark display process displays vibration point marks indicating points where the vibration of the transport vehicle is relatively large on a map on the travel route in a first display area on the display screen of the display device. As a result, a person who sees the first display area can easily understand at which point on the travel route a large vibration is occurring. Furthermore, according to this configuration, when the playback display process accepts an operation on the vibration point mark, playback display is performed from a point upstream of the point indicated by the vibration point mark, so that information can be displayed on the display device that makes it easy to understand the shape and structure of the travel route before and after a point on the travel route where the vibration of the transport vehicle is relatively large, and the travel speed of the transport vehicle.
