Description

Technical Field

[0001] The present invention relates to an information display system including a display device for displaying information, a control device for controlling the display device, and a recording device. Background Art

[0002] An example of such an information display system is disclosed in the following Patent Document 1 (Japanese Patent Application Laid-Open No. 2016-52919). In the following description of the background art, the symbols and names in Patent Document 1 are cited in parentheses.

[0003] The information display system of patent document 1 comprises: a display device (display 128) which displays information; and a recording device (memory 123) which stores position information indicating the position of a transport vehicle (112) in association with the time at which the transport vehicle is located. Furthermore, in the display device (128), a transport vehicle mark (transport vehicle icon 133) indicating the position of the transport vehicle (112) corresponding to a predetermined time is displayed on a map (route map 132) of the travel route of the transport vehicle (112).

[0004] In addition, the storage device (123) stores the status information showing the status of the transport vehicle (112) in association with the time when the status information is obtained. In addition, in the display device (128), in addition to the map (132) of the driving route of the transport vehicle (112) and the display area of ​​the transport vehicle mark (133), a display area of ​​a status curve graph (134) that intuitively shows the change of the status information corresponding to a predetermined time with time is also provided.

[0005] Patent document 1 records, as status information indicating the status of the transport vehicle (112), the status of the operating mode of the transport vehicle (112), an abnormality code indicating the type of abnormality, the detection status of multiple cargo sensors installed on the lifting platform (114), information on whether there is cargo on the lifting platform (114), the output value of the encoder installed corresponding to the front wheels and the rear wheels of the trolley (113), the speed obtained based on the output value of the encoder and the time information of the timer, the output voltage value of the battery mounted on the transport vehicle (112), and other information. Summary of the invention

[0006] When the transport vehicle is traveling, it is useful to know the magnitude of vibration measured in the transport vehicle. For example, if it is known at which location in the travel path of the transport vehicle a large vibration is measured, it can be inferred that some abnormality has occurred in the travel path at that location. However, in the technology described in Patent Document 1, there is no operation of obtaining information on the vibration of the transport vehicle as status information indicating the status of the transport vehicle.

[0007] Furthermore, in the technology of Patent Document 1, the state curve diagram only shows the change of state information over time within a predetermined period, and even if the state curve diagram is observed, it is not clear which part of the state curve diagram showing the change of state information over time within a predetermined period shows the state at a predetermined time corresponding to the position of the transport vehicle mark. That is, in the change of state information over time shown in the state curve diagram, even if one wants to confirm the state at a particularly specified time, it is not easy to understand at which place on the driving path the transport vehicle is traveling at that time.

[0008] Therefore, it is desired to realize an information display system that can easily understand the relationship between the shape or structure of the travel path of the transport vehicle and the vibration.

Solutions to Solve the Problem

[0009] In view of the above, the information display system is characterized in that: the information display system is an information display system including a display device for displaying information, a control device for controlling the display device, and a recording device, the recording device recording data that establishes an association between position information showing the position of the transport vehicle and vibration information showing vibration measured in the transport vehicle, namely, transport vehicle travel data, and data of a map of a travel route that the transport vehicle has traveled, namely, path map data, the control device: setting a first display area and a second display area on a display screen of the display device, and performing the following processing: map display processing, which displays at least a part of the map based on the path map data in the first display area; transport vehicle display processing, which displays a transport vehicle mark showing the position of the transport vehicle at a display target time point on the map displayed in the first display area by the map display processing; graph display processing, which displays a vibration result graph showing the vibration information at least at the display target time point and the time before and after the display in the second display area; and position mark display processing, which displays a position mark showing a position on the vibration result graph corresponding to the display target time point in the second display area.

[0010] According to this configuration, through map display processing and transport vehicle display processing, the first display area in the display screen of the display device displays a map of the travel path and the position of the transport vehicle on the map at the display object time point. Through graph display processing and position mark display processing, the second display area in the display screen of the display device displays a vibration result graph showing vibration information at least at the display object time point and before and after it and a position mark showing the position corresponding to the above-mentioned display object time point on the vibration result graph. That is, a person who observes the display screen including the first display area and the second display area can intuitively and easily grasp what kind of vibration is measured when the transport vehicle is at which position in the travel path. Therefore, it is possible to realize an information display system that can easily grasp the relationship between the shape or structure of the travel path shown by the map and the vibration.

[0012] An embodiment of the information display system is described based on the accompanying 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 articles is described. Therefore, in the following description, first, an example is described in which the vibration measuring device 20 is mounted on the transport vehicle 3 that transports articles, and the vibration measuring device 20 performs vibration measurement. Figure 1 1 is a top view of the article transport facility 200 that performs vibration measurement using the vibration measuring device 20 . Figure 2 It is a side view of the transport vehicle 3 on which the vibration measuring device 20 is mounted. Figure 3 It is a schematic block diagram showing the configuration of the transport vehicle 3 and the vibration measuring device 20 . Figure 4 and Figure 5 1 is an explanatory diagram of the operating state of the guide wheel 17 provided in the transport vehicle 3. In the following description, the direction along the travel path 1 is referred to as the travel direction Y, and the direction along the horizontal plane and perpendicular to the travel direction Y is referred to as the width direction X. The up-down direction Z is a direction perpendicular to the traveling direction Y and the width direction X.

[0013] The article conveying device 200 includes: a travel track 2, which is suspended and supported on the ceiling and is arranged along the travel path 1; and a conveying vehicle 3, which is suspended and supported on the travel track 2, travels along the travel path 1 on the travel track 2, and conveys the container W. That is, the conveying vehicle 3 described in this embodiment is a so-called ceiling conveying vehicle. The conveying vehicle 3 conveys, for example, a FOUP (Front Opening Unified Pod) or the like containing articles such as wafers used as materials for semiconductor substrates as containers W.

[0014] like Figure 1 As shown, the travel path 1 has, for example, a ring-shaped main path 1M, a plurality of ring-shaped 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 one-way traffic. The transport vehicle 3 travels on the travel path 1 from the upstream side of the travel direction Y toward the downstream side of the travel direction Y. The travel path 1 includes an area passed through when transporting a container W, namely the transport area E1, and an area passed through when performing maintenance on the transport vehicle 3, namely the maintenance area E2. In the maintenance area E2, for example, a maintenance elevator 204 is provided for maintenance, and the maintenance elevator 204 is used to lower the transport vehicle 3 suspended on the travel track 2 to the ground side. As shown in FIG. Figure 4 and Figure 5 As shown, the transport vehicle 3 is guided by a pair of travel rails 2 .

[0015] The processing device 202 is, for example, a semiconductor processing device for performing various processes such as exposure processing or etching processing. In this case, in the article conveying device 200, the FOUP is conveyed as a container W. In addition, the container W and the article contained in the container W may also be other objects. For example, the conveying vehicle 3 may also convey a mask used for exposure processing of a wafer in the manufacturing process of a semiconductor substrate as an article and a mask box containing the mask as a container W. A loading table 203 is also provided at each processing device 202.

[0016] like Figure 2 As shown, the transport vehicle 3 includes: a travel mechanism 5, which is guided by a travel track 2 arranged to be suspended from the ceiling along the travel path 1, and travels along the travel path 1; and a transport vehicle body 12, which is located below the travel track 2 and is suspended from the travel mechanism 5. The transport vehicle 3 includes a holding mechanism 6 for suspending and holding the container W and a lifting mechanism 7 for raising and lowering the holding mechanism 6. Figure 2 As shown, the transport vehicle 3 transports the container W while traveling in a state where the holding mechanism 6 is raised.

[0017] like Figure 2 , Figure 4 as well as Figure 5 As shown, 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 (traveling motor). The traveling wheels 15 roll on a traveling surface formed by the upper surface of each traveling rail 2. Although not shown in detail, the traveling mechanism 5 is provided with a pair of traveling auxiliary wheels 16 that are freely rotatable around an axis (around an upper and lower axis) along the up-down direction Z in a state where the pair of traveling auxiliary wheels 16 abut against the inner side surface of each traveling rail 2 in the pair of traveling rails 2.

[0018] like Figure 4 and Figure 5As shown, in the branch section of the travel path 1, there is a guide track 13 extending in the direction along the travel direction Y of the transport vehicle 3. In addition, although not shown in the figure, the same guide track 13 is also provided in the merging section of the travel path 1. The guide track 13 includes a pair of guide surfaces 14 (a first guide surface 14a and a second guide surface 14b). The pair of guide surfaces 14 (the first guide surface 14a and the second guide surface 14b) are the first guide surface 14a and the second guide surface 14b facing opposite sides in the width direction X orthogonal to the travel direction Y and extending along the travel direction Y respectively. The transport vehicle 3 is provided with a guide wheel 17 that rotates around a longitudinal axis (around the upper and lower axis) along the up and down direction Z. The guide wheel 17 is provided in such a manner that it can change position further to the right and left than the guide rail 13 arranged in the center portion between the pair of left and right travel rails 2, and the guide wheel 17 rotates by contacting the right guide surface 14 of the guide rail 13, namely the first guide surface 14a, or the left guide surface 14, namely the second guide surface 14b.

[0019] As described below, the vehicle control unit 4 included in the transport vehicle 3 causes the travel mechanism 5 to perform a switching operation to selectively bring the guide wheels 17 into contact with one of the pair of guide surfaces 14 in the diverging section and the merging section.

[0020] Figure 4 This is an example of a case where the transport vehicle 3 is caused to travel on a path to the right in the travel direction Y in the branch section (in this example, to travel straight). In this case, the vehicle control unit 4 positions the guide wheel 17 on the first guide surface 14a side of the guide rail 13 (to the right in the travel direction Y). As a result, the transport vehicle 3 travels in a state where the first guide surface 14a of the guide rail 13 is in contact with the guide wheel 17. Figure 4 As shown, when the transport vehicle 3 goes straight through the path on the right side (the first side X1 in the width direction) in the branch section, the travel track 2 on one side (here, the left side) of the pair of travel tracks 2 is interrupted, and the left travel wheel 15 and the travel auxiliary wheel 16 are in a state of being disengaged. Figure 4 In the figure, the auxiliary travel wheels 16 are omitted for simplicity. However, the guide rail 13 receives and guides the load of the transport vehicle 3 via the guide wheels 17, thereby preventing the transport vehicle 3 from falling off the travel rail 2, and the transport vehicle 3 can travel straight in the branch section.

[0021] Figure 5This is an example of making the transport vehicle 3 travel along a path to the left in the driving direction Y in the branch section (in this example, branching along a curved path). In this case, the vehicle control unit 4 makes the guide wheel 17 located on the second guide surface 14b side of the guide rail 13 (to the left in the driving direction Y). As a result, the transport vehicle 3 is guided in a state where the second guide surface 14b of the guide rail 13 is in contact with the guide wheel 17. Figure 5 As shown, when the transport vehicle 3 branches through the path on the left side (the second side X2 in the width direction) in the branch section, the travel track 2 on one side (here, the right side) of the pair of travel tracks 2 is interrupted, and the right travel wheel 15 and the travel auxiliary wheel 16 are in a state of being disengaged. However, the guide rail 13 blocks and guides the load supporting the transport vehicle 3 via the guide wheel 17, thereby preventing the transport vehicle 3 from falling off the travel track 2, and the transport vehicle 3 can branch and travel in the branch section.

[0022] like Figure 3 As shown, the transport vehicle 3 includes a position monitoring sensor 8 , a speed sensor 9 , an object monitoring sensor 10 , and a communication unit 11 in addition to the above.

[0023] The vehicle control unit 4 controls the movement of the transport vehicle 3. For example, the vehicle control unit 4 can communicate information with the device control unit H that manages the entire article transport facility 200 through wireless communication via the communication unit 11. Furthermore, based on the transport instruction from the device control unit H, the vehicle control unit 4 autonomously controls the transport vehicle 3 to travel, transport the container W between different loading platforms 203, stop above the designated loading platform 203, and raise or lower the holding mechanism 6, thereby transferring the container W.

[0024] In order to detect the position of the transport vehicle 3, a position monitoring sensor 8 is used. Figure 3 As shown, in the driving path 1, a position mark B showing the position in the driving path 1 is arranged along the driving path 1. The position mark B can be set as a one-dimensional or two-dimensional bar code, or a mark with numbers or characters recorded on it. The position monitoring sensor 8 can be set as a bar code reader or an image recognition device, or a character recognition device that recognizes numbers or characters. The position monitoring sensor 8 can use a sensor that detects the rotation angle of the axle (not shown) of the driving wheel 15 to derive the travel distance of the transport vehicle 3. Moreover, the position monitoring sensor 8 can detect the current position of the transport vehicle 3 in the driving path 1 based on the travel distance of the transport vehicle 3 from the detection of the position mark B. The position information detected by the position monitoring sensor 8 is transmitted to the vehicle control unit 4. In this way, the transport vehicle 3 can use multiple position marks B to detect the position in the driving path 1. The transport vehicle 3 sends the detected position information to the device control unit H one by one, and the device control unit H can send the transport instruction generated based on the position information to the transport vehicle 3.

[0025] In order to detect the travel speed of the transport vehicle 3, a speed sensor 9 is used. For example, the speed sensor 9 can be implemented using a sensor that detects the rotation angle of the axle (not shown) of the running wheel 15. In this case, the speed sensor 9 can derive the rotation speed of the axle based on the rotation angle of the axle (not shown) of the running wheel 15, and derive the travel speed of the transport vehicle 3 based on the rotation speed. Moreover, the speed sensor 9 only needs to transmit the derived travel speed to the vehicle control unit 4. Alternatively, the speed sensor 9 can successively transmit the measured rotation angle of the axle (not shown) of the running wheel 15 to the vehicle control unit 4, and the vehicle control unit 4 derives the travel speed of the transport vehicle 3 based on the value of the rotation angle.

[0026] The object monitoring sensor 10 is used to monitor objects that become obstacles for the traveling transport vehicle 3. For example, there are multiple transport vehicles 3 on the travel path 1, and the multiple transport vehicles 3 travel at the same time. Therefore, in order to prevent collision with other transport vehicles 3, the transport vehicle 3 is provided with an object monitoring sensor 10, which detects objects existing in a set area in front of the travel direction Y.

[0027] Figure 6 and Figure 7 3 is a diagram illustrating the monitoring area 18 of the object monitoring sensor 10 of the transport vehicle 3. Figure 6 As shown in FIG. 1 , when the front of the transport vehicle 3 in the travel direction Y is a straight section, the monitoring area 18 set in front of the transport vehicle 3 in the travel direction Y is made to be longer in the travel direction Y than in the width direction X. Figure 7 As shown, when there is a curved section ahead of the transport vehicle 3 in the driving direction Y, the monitoring area 18 set ahead of the transport vehicle 3 in the driving direction Y is made to extend longer in the width direction X than in the driving direction Y in accordance with the curved driving path 1.

[0028] Next, the vibration measuring device 20 mounted on the transport vehicle 3 will be described. Figure 3As shown, the vibration measuring device 20 includes: a vibration measuring unit 21 that measures vibration; a position information acquisition unit 22 that acquires position information indicating the position of the transport vehicle 3; a state information acquisition unit 23 that acquires transport vehicle state information indicating the state of the transport vehicle 3; a recording unit 24 that records the measurement result measured 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 that outputs the information recorded in the recording unit 24. In addition, the vibration measuring device 20 includes an information communication function, an information calculation processing function, an information storage function, etc. As described later, at least a part of these functions may be used to realize the functions of the vibration measuring unit 21, the position information acquisition unit 22, the state information acquisition unit 23, the recording unit 24, and the output unit 25. The vibration measuring device 20 may be realized by a single device equipped with these functions, or by a plurality of devices equipped with these functions.

[0029] The vibration measuring unit 21 can be implemented using a sensor that can measure physical quantities representing vibrations, such as the amplitude, frequency, and acceleration of vibrations. The vibration measuring unit 21 can be configured to measure vibrations in three mutually orthogonal directions, namely, the X direction, the Y direction, and the Z direction, for example. Alternatively, the vibration measuring unit 21 can be configured to measure vibrations in two directions or one direction among the X direction, the Y direction, and the Z direction. The vibration measuring unit 21 can also obtain time information about the time when the measurement result of the vibration is obtained together with the measurement result of the vibration.

[0030] The position information acquisition unit 22 acquires position information indicating the position of the transport vehicle 3. For example, the position information acquisition unit 22 acquires position information indicating the position of the transport vehicle 3 monitored by the position monitoring sensor 8 of the transport vehicle 3 using the information communication function of the vibration measurement device 20. The position information acquisition unit 22 may acquire time information about the time when the position information is monitored together with the position information.

[0031] The state information acquisition unit 23 acquires the transport vehicle state information indicating the state of the transport vehicle 3. For example, the state information acquisition unit 23 acquires the transport vehicle state information measured in the transport vehicle 3 using the information communication function of the vibration measuring device 20. The state information acquisition unit 23 may acquire time information about the time when the transport vehicle state information is measured together with the transport vehicle state information.

[0032] The transport vehicle state information includes at least one of the travel speed of the transport vehicle 3 , the acceleration state of the transport vehicle 3 , the operation state of the operation mechanism of the transport vehicle 3 , and the monitoring state of the sensor (eg, the object monitoring sensor 10 ) of the transport vehicle 3 .

[0033] 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 accelerated state, a decelerated 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. Alternatively, the vehicle control unit 4 of the transport vehicle 3 calculates the acceleration state of the transport vehicle 3, and the state information acquisition unit 23 of the vibration measuring device 20 obtains the calculated acceleration state. Alternatively, the state information acquisition unit 23 of the vibration measuring device 20 may calculate the acceleration state based on the obtained travel speed of the transport vehicle 3 using the calculation processing function of the vibration measuring device 20. For example, it can be considered that the vibration of the transport vehicle 3 is relatively large when the transport vehicle 3 is accelerated and when it is decelerated, and the vibration of the transport vehicle 3 is relatively small when the transport vehicle 3 is traveling at a constant speed.

[0034] The operating state of the operating mechanism of the transport vehicle 3 is information about the operating state of the operating mechanism of the transport vehicle 3, such as the travel mechanism 5, the holding mechanism 6, and the lifting mechanism 7. Figure 4 and Figure 5 The guide wheel 17 shown is a part of the traveling mechanism 5, and the movement of the guide wheel 17 is controlled by the vehicle control unit 4. Moreover, the state information acquisition unit 23 can obtain information showing which side the guide wheel 17 is located on, the right side or the left side, in the traveling direction Y from the vehicle control unit 4 of the transport vehicle 3. In addition, the operation state is not limited to the state of the guide wheel 17 (i.e., the traveling mechanism 5). For example, it can also be the operation state of the lifting mechanism 7, the operation state of the holding mechanism 6, etc. For example, it can be considered that when the guide wheel 17 of the traveling mechanism 5 is in operation (i.e., when the position of the guide wheel 17 is switched left and right), the vibration of the transport vehicle 3 is relatively large.

[0035] The monitoring state of the object monitoring sensor 10 provided on the transport vehicle 3 is, for example, Figure 6 and Figure 7 The shape of the monitoring area 18 of the object monitoring sensor 10 shown in the figure or the information on whether an object is monitored, etc. The vehicle control unit 4 controls the state of the monitoring area 18 of the object monitoring sensor 10 of the transport vehicle 3. The information on whether the object monitoring sensor 10 monitors the object is transmitted to the vehicle control unit 4. In addition, the state information acquisition unit 23 can obtain information about the monitoring state of the object monitoring sensor 10 of the transport vehicle 3 from the vehicle control unit 4 of the transport vehicle 3. For example, it can be considered that the vibration of the transport vehicle 3 is relatively large due to the reason that the transport vehicle 3 decelerates when the object monitoring sensor 10 monitors the object.

[0036] As described above, the state information acquisition unit 23 can acquire, as the transport vehicle state information, information indicating the behavior of the transport vehicle 3 that may affect the vibration measured by the vibration measurement unit 21. Therefore, the user can easily analyze whether the vibration is strongly affected by the state of the transport vehicle 3 by referring to such transport vehicle state information.

[0037] The recording unit 24 records the measurement results (vibration information), the transport vehicle status information, and the position information measured by the vibration measuring unit 21 in association with each other. The recording unit 24 can be realized by using the information storage function possessed by the vibration measuring device 20. For example, as described above, when the measurement results, the transport vehicle status information, and the position information measured by the vibration measuring unit 21 are all associated with the time information, the recording unit 24 can record the measurement results, the transport vehicle status information, and the position information measured by the vibration measuring unit 21 at the same time or within a predetermined time range in association with each other. In addition, when these information are not associated with the time information, the recording unit 24 only needs to record the measurement results, the transport vehicle status information, and the position information measured by the vibration measuring unit 21 recorded at the same time or within a predetermined time as a data set in association with each other.

[0038] The vibration information may be a physical quantity representing vibration, such as the amplitude, frequency, acceleration, etc., measured by the vibration measuring unit 21, or a value calculated from these. For example, the vibration information may be an effective value (RMS: root mean square) calculated from the vibration waveform.

[0039] In this way, the recording unit 24 can record: at least the transport vehicle travel data that establishes an association between the position information showing the position of the transport vehicle 3 and the vibration information showing the vibration measured in the transport vehicle 3; or at least the transport vehicle travel data that establishes an association between the position information showing the position of the transport vehicle 3, the vibration information showing the vibration measured in the transport vehicle 3, and the transport vehicle status information showing the status of the transport vehicle 3. The time information can also be associated with the position information, vibration information, and transport vehicle status information included in the transport vehicle travel data. The recording unit 24 can record the information of the position that the transport vehicle 3 has passed during travel as the data of the map of the travel route 1 that the transport vehicle 3 has traveled, that is, the path map data. The time information can also be associated with the information of the position that the transport vehicle 3 has passed during travel.

[0040] The output unit 25 outputs the information recorded in the recording unit 24. For example, the output unit 25 can output the information recorded in the recording unit 24 to other devices that can communicate with the vibration measuring device 20 using the information communication function of the vibration measuring device 20. In addition, the output unit 25 not only outputs the information in the form of sending it to other devices, but also can display the information on the display device 41, print it on paper, and output the information to a removable storage device.

[0041] As described above, by using the vibration measuring device 20 of the present embodiment, it is possible to obtain information showing the vibration measured at each position of the travel path 1 where the transport vehicle 3 has traveled and the state of the transport vehicle 3 at that position. As a result, the user who receives the output of this information can appropriately grasp the information about which position of the travel path 1 of the transport vehicle 3 the vibration becomes larger and what state the transport vehicle 3 is in at that time. That is, according to the vibration measuring device 20 involved in the present embodiment, it is possible to output information for appropriately analyzing the cause of the measured vibration.

[0042] Next, the information display system will be described. Figure 8 : is a diagram for explaining the configuration of the information display system. As shown in the figure, the information display system includes a display device 41 for displaying information, a control device 40 for controlling the display device 41, a recording device 45, and an input receiving unit 56. The information display system can be realized by using a single or multiple computer devices having an information display function (i.e., the display device 41), an information communication function, an information calculation processing 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).

[0043] The recording device 45 records: data that establishes a correlation between position information showing the position of the transport vehicle 3 and vibration information showing the vibration measured in the transport vehicle 3, namely, the transport vehicle travel data; and data of a map of the travel path 1 on which the transport vehicle 3 has traveled (i.e., information on the positions that the transport vehicle 3 has passed during travel), namely, the path map data. That is, the transport vehicle travel data and the path map data establish a relationship at the positions of each time point during the travel of the transport vehicle 3. Therefore, if the position of the transport vehicle 3 at a specially specified time point is specified, the vibration information at the position is specially specified, and it is specially specified which part of the map of the travel path 1 the position corresponds to.

[0044] The data output from the output unit 25 of the vibration measuring device 20 is used to create the transport vehicle travel data and path map data recorded in the recording device 45. For example, in the case where the computer device implementing the information display system and the vibration measuring device 20 can communicate information with each other, it is sufficient to output the information included in the transport vehicle travel data and the path map data from the output unit 25 of the vibration measuring device 20 to the computer device implementing the information display system. Alternatively, the output unit 25 of the vibration measuring device 20 outputs the information included in the transport vehicle travel data and the path map data to a portable storage device, and then the portable storage device is connected to the computer device implementing the information display system and the stored information is read out, so that the information included in the transport vehicle travel data and the path map data can be recorded in the recording device 45.

[0045] 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 transport vehicle display process, a graph display process, and a position mark display process as described later.

[0046] The map display process is a process of displaying at least a portion of a map based on the route map data in the first display area 43. Figure 8 In the example shown, 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 the positions that the transport vehicle 3 has passed during travel with a line. Alternatively, the control device 40 can also display the travel route map using the travel route mark 46 when map information of the travel route 1 already exists, such as when the travel track 2 is laid.

[0047] The transport vehicle display process is a process of displaying a transport vehicle mark 47 showing the position of the transport vehicle 3 at the display target time point on the map (travel route mark 46) displayed in the first display area 43 by the map display process. Figure 8 In the example shown, the control device 40 displays a transport vehicle mark 47 at a location corresponding to the position of the transport vehicle 3 at a specially specified time point (i.e., the display object time point) in the travel route map displayed by the travel route mark 46, based on the route map data which is the data of the map of the travel route 1 that the transport vehicle 3 has traveled (i.e., information on the positions that the transport vehicle 3 has passed during travel). In addition, the shape, pattern, etc. of the transport vehicle mark 47 can be appropriately set.

[0048] The graph display process is a process of displaying a vibration result graph 48 showing vibration information at least at the display target time point and the time before and after it in the second display area 44. Figure 8In the example shown, the control device 40 displays a vibration result graph 48 that graphs the transition of vibration information at a specifically specified time point (i.e., the display object time point) and the time before and after it based on data that establishes an association between position information showing the position of the transport vehicle 3 and vibration information showing the vibration measured in the transport vehicle 3, i.e., transport vehicle travel data.

[0049] The position mark display process is a process of 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. Figure 8 In the example shown, the control device 40 displays a dotted line 49a indicating a display target time point and an arrow 49b indicating the dotted line 49a as the position mark 49. The shape, pattern, etc. of the position mark 49 can be set as appropriate.

[0050] In this way, through the map display processing and the transport vehicle display processing, the first display area 43 in the display screen 42 of the display device 41 displays the map of the travel route 1 and the position of the transport vehicle 3 on the map at the display object time point. Through the curve display processing and the position mark display processing, the second display area 44 in the display screen 42 of the display device 41 displays the vibration result curve 48 showing the vibration information at least at the display object time point and before and after it and the position mark 49 showing the position corresponding to the above-mentioned display object time point on the vibration result curve 48. That is, a person who observes the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily grasp what kind of vibration is measured when the transport vehicle 3 is at which position on the travel route 1. Therefore, it is possible to realize an information display system that can easily grasp the relationship between the shape or structure of the travel route 1 shown by the map and the vibration.

[0051] Alternatively, the transport vehicle travel data may further include travel speed information indicating the travel speed of the transport vehicle 3, and the travel speed information may be data associated with the position information and the vibration information. Furthermore, the control device 40 may also perform the following reproduction display processing: in the transport vehicle display processing, the transport vehicle mark 47 is moved relative to the map at a speed corresponding to the travel speed of the transport vehicle 3 based on the transport vehicle travel data, and in the position mark display processing, the position mark 49 is moved relative to the vibration result curve 48 at a speed corresponding to the moving speed of the transport vehicle mark 47. Alternatively, the control device 40 may also move the transport vehicle mark 47 relative to the map at a certain speed that is independent of the travel speed of the transport vehicle 3.

[0052] Although not shown in the figure, the control device 40 may display buttons for controlling reproduction, such as a reproduction start button or a reproduction stop button, on the display screen 42, and perform reproduction display processing in accordance with input operations (i.e., instructions related to reproduction display, such as reproduction start and reproduction stop) performed by the user through the input receiving unit 56 such as a mouse. Alternatively, the control device 40 may automatically perform reproduction display processing even if the user does not perform an input operation on the reproduction start button.

[0053] By executing such map display processing, transport vehicle display processing, and playback display processing, a map of the travel route 1 and a transport vehicle mark 47 showing the position of the transport vehicle 3 at the display target time point on the map are displayed in the first display area 43 in the display screen 42 of the display device 41, and the transport vehicle mark 47 moves relative to the map at a speed corresponding to the travel speed of the transport vehicle 3 based on the transport vehicle travel data. By executing the graph display processing, the position mark display processing, and playback display processing, a vibration result graph 48 showing vibration information at least at the display target time point and before and after the display target time point and a position mark 49 showing the position on the vibration result graph 48 corresponding to the above-mentioned display target time point are displayed in the second display area 44 in the display screen 42 of the display device 41, and the position mark 49 moves relative to the vibration result graph 48 at a speed corresponding to the travel speed of the transport vehicle 3 based on the transport vehicle travel data. That is, a person viewing the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily understand at which position of the transport vehicle 3 on the travel path 1 the transport vehicle 3 is, at what speed the transport vehicle 3 moves, and at what value the vibration changes.

[0054] For example, the control device 40 is capable of performing a reproduction display processing in the first display area 43, such as fixing the display position of the transport vehicle mark 47 and moving the travel route mark 46 showing the travel route map, or a reproduction display processing such as fixing the travel route mark 46 showing the travel route map and moving the display position of the transport vehicle mark 47, or a reproduction display processing such as moving both the display position of the transport vehicle mark 47 and the travel route mark 46 showing the travel route map, etc.

[0055] The control device 40 is capable of performing a reproduction display processing in the second display area 44, such as fixing the display position of the position mark 49 indicating the display object time point and moving the vibration result curve graph 48, or fixing the display of the vibration result curve graph 48 and moving the display position of the position mark 49 indicating the display object time point, or a reproduction display processing such as moving both the display position of the position mark 49 indicating the display object time point and the vibration result curve graph 48.

[0056] The control device 40 can change the information displayed in the first display area 43 and the second display area 44 according to, for example, an instruction received from the user by the input receiving unit 56. Some display screen examples in the first display area 43 and the second display area 44 are described below.

[0057] Fig. 9 4 is a diagram showing an example of a display screen of the display device 41. In this example, the transport vehicle driving data also includes transport vehicle status information showing the status of the transport vehicle 3, and the transport vehicle status information becomes data associated with the position information and the vibration information. Moreover, in the graph display processing, the control device 40 displays the transport vehicle status curve graph 50 showing the transport vehicle status information at least at the display object time point and the time before and after it in the second display area 44 together with the vibration result curve graph 48, and in the position mark display processing, the position corresponding to the display object time point on the transport vehicle status curve graph 50 is displayed in the second display area 44 through the position mark 49.

[0058] exist Fig. 9 In the example shown, the information about the travel speed of the transport vehicle 3 is used as the transport vehicle state information. Moreover, the control device 40, in the graph display processing, based on the information about the travel speed of the transport vehicle 3 (transport vehicle state information) and the position information and vibration information, establishes data, that is, the transport vehicle travel data, which is associated, and displays the vibration result graph 48 and the transport vehicle state graph 50 that graphs the transition curve of the vibration information at a specially specified time point (that is, the display object time point) and the time before and after. In this way, a person who observes the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily grasp what kind of vibration is measured and what state the transport vehicle 3 is when the transport vehicle 3 is at which position of the travel path 1. As a result, there is an advantage that it is easy to easily grasp the relationship between the shape or structure of the travel path 1 shown by the map, the vibration and the state of the transport vehicle 3.

[0059] In addition, Fig. 9 In the embodiment, 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 this case, the position mark 49 only needs to be displayed in each second display area 44.

[0060] Furthermore, the control device 40 executes a transportation vehicle state display process for displaying a transportation vehicle state mark 51 indicating transportation vehicle state information on the map displayed by the map display process, in correspondence with the transportation vehicle mark 47 displayed by the transportation vehicle display process.

[0061] exist Fig. 9 In the example shown, information about the operating state of the guide wheel 17 (i.e., the state of which side the guide wheel 17 is located on, the right side or the left side, in the driving direction Y) is used as the transport vehicle state information. Moreover, in the transport vehicle state display processing, the control device 40 displays the transport vehicle state mark 51 showing the operating state of the guide wheel 17 corresponding to the transport vehicle mark 47 displayed by the transport vehicle display processing on the map displayed by the map display processing, based on the information about the operating state of the guide wheel 17 (transport vehicle state information) and the data associated with the position information and the vibration information, that is, the transport vehicle driving data. In the example shown, the state of the guide wheel 17 being located on the left side in the driving direction Y is displayed. In this way, a person observing the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily understand what kind of vibration is measured and what state the guide wheel 17 of the transport vehicle 3 is in when the transport vehicle 3 is at which position on the driving path 1.

[0062] Fig.10 and Fig.11 is a diagram showing an example of a display screen of the display device 41. In this example, the transport vehicle travel data also includes transport vehicle status information showing the status of the transport vehicle 3, and the transport vehicle status information is data associated with the position information and the vibration information. Moreover, the control device 40 further performs the following transport vehicle status display processing: on the map displayed by the map display processing, the transport vehicle status mark 51 showing the transport vehicle status information is displayed corresponding to the transport vehicle mark 47 displayed by the transport vehicle display processing.

[0063] exist Fig.10 and Fig.11 In the example shown, the information about the travel speed of the transport vehicle 3 is used as the transport vehicle status information. Furthermore, in the transport vehicle status display processing, the control device 40 establishes data related to the information about the travel speed of the transport vehicle 3 (the transport vehicle status information) and the position information and the vibration information, and displays the transport vehicle status mark 51 indicating the travel speed of the transport vehicle 3 on the map displayed by the map display processing in correspondence with the transport vehicle mark 47 displayed by the transport vehicle display processing. For example, in Fig.10 and Fig.11 In the example, the dashed arrow as the transport vehicle status mark 51 shows the travel speed of the transport vehicle 3 as the transport vehicle status information. In this case, the longer the dashed arrow is, the faster the travel speed is. That is, Fig.10 The dashed arrow shown as the transport vehicle status mark 51 is Fig.11 The dotted arrow shown as the transport vehicle status mark 51 is longer in shape, so it can be seen that Fig.10Thus, a person who observes the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily understand what vibration is measured and what state the speed of the transport vehicle 3 is when the transport vehicle 3 is at which position on the travel path 1.

[0064] 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 also includes monitoring area information showing the state of the monitoring area 18 of the object monitoring sensor 10 possessed by the transport vehicle 3, and the monitoring area information becomes data associated with the position information and the vibration information. Moreover, the control device 40 further performs the following monitoring area display processing: based on the transport vehicle travel data, on the map displayed by the map display processing, a monitoring area mark 53 showing the state of the monitoring area 18 at the display object time point is displayed corresponding to the transport vehicle mark 47 displayed by the transport vehicle display processing. For example, in Fig.12 In FIG. 1 , as the state information of the transport vehicle, the shape of the monitoring area 18 in the horizontal direction is displayed using a dotted line graphic as a monitoring area mark 53 . Fig.12 The shape of the monitoring area mark 53 shown is similar to Figure 7 The shape of the monitoring area 18 shown is the same. In this way, a person who observes the display screen 42 including the first display area 43 and the second display area 44 can intuitively and easily understand what kind of vibration is measured and what state the monitoring area 18 of the object monitoring sensor 10 of the transport vehicle 3 is in when the transport vehicle 3 is at which position on the travel path 1. In addition, the shape, pattern, etc. of the monitoring area mark 53 can be appropriately set.

[0065] Fig.13 4 is a diagram showing an example of a display screen of the display device 41. In this example, the control device 40 further performs the following path shape display processing: in the second display area 44, a path shape display 52 showing the characteristics of the shape of the travel path 1 on which the transport vehicle 3 has traveled is displayed in correspondence with the position where the vibration shown by the vibration result graph 48 is measured. Fig.13 In the example shown, the pattern of a part of the second display area 44 (the part corresponding to the curved section of the travel route 1) is different from the other parts. In addition, a path shape display 52 of "180° inner circle R500" is displayed, which means that the curved section is a 180° rotation with a curvature radius of 500 mm on the inner circle side of the travel route 1. In this way, a person who observes the display screen 42 including the second display area 44 can intuitively and easily understand the relationship between the shape of the travel route 1 and the vibration.

[0066] Fig.14is a diagram showing an example of a display screen of the display device 41. In this example, the control device 40 performs the following vibration location mark display processing: a vibration location mark 54 is displayed on the map, and the vibration location mark 54 shows a location on the driving path 1 where the vibration value indicated by the vibration information exceeds a predetermined judgment threshold. In the first display area 43, a mouse pointer 55 is also displayed. In this way, a person observing the first display area 43 can easily understand at which location on the driving path 1 a large vibration occurs. Fig.14 The first display area 43 shown further displays a transport vehicle state mark 51 indicating the travel speed of the transport vehicle 3 .

[0067] The control device 40 can further perform the following operation acceptance processing: accepting a selection operation of the vibration location mark 54 displayed by the vibration location mark display processing. For example, the user can operate the input acceptance unit 56 such as a mouse to perform a selection input of a specially specified vibration location mark 54 through the mouse pointer 55. In addition, when the control device 40 has accepted the selection operation of the vibration location mark 54 through the operation acceptance processing, as shown in FIG. Fig.15 As shown, the reproduction and display processing starts from a point on the upstream side of the point indicated by the vibration point mark 54.

[0068] In this way, through the reproduction display processing, when the operation of the vibration location mark 54 has been accepted, the reproduction display is performed from a location further upstream than the location indicated by the vibration location mark 54, so that information such as the shape or structure before and after the location where the vibration of the transport vehicle 3 on the travel path 1 is relatively large and the travel speed of the transport vehicle 3 can be displayed on the display device 41, which makes it easy to understand.

[0069] Next, other embodiments of the information display system will be described.

For example, the position monitoring sensor 8 may also detect the position of the transport vehicle 3 by receiving a signal from a GNSS (Global Navigation Satellite System) satellite that creates a GNSS.

[0072] (3) In the above-mentioned embodiment, the content of the transport vehicle status information can be appropriately changed. For example, it can also include information on the monitoring status of various sensors provided in the transport vehicle 3. Examples of various sensors provided in the transport vehicle 3 include a sensor for detecting the operating status of the holding mechanism 6 for holding the container W, a sensor for detecting the operating status of the lifting mechanism 7 for lifting the holding mechanism 6, and the like.

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. A display area different from the first display area 43 and the second display area 44 may also be displayed on the display screen 42.

For example, the horizontal axis may be the total travel distance of the transport vehicle 3, the order of recorded information, etc.

For example, the control device 40 can also perform the reproduction display processing as follows: in the first display area 43, when the user has used the input receiving unit 56 such as a mouse to select and move the transport vehicle mark 47 (i.e., drag the transport vehicle mark 47 with the mouse), the transport vehicle mark 47 is moved relative to the map (travel path mark 46) in accordance with the instruction, and the position mark 49 is moved relative to the vibration result curve graph 48 in the second display area 44 accordingly.

[0077] (8) In the above embodiment, Fig.10 and Fig.11 The example of the transport vehicle status mark 51 showing the travel speed of the transport vehicle 3 shown by the dashed arrow is described, but the display form of the transport vehicle status mark 51 can be appropriately changed. For example, a numerical value (i.e., text information) showing the travel speed of the transport vehicle 3 can also be displayed as the transport vehicle status mark 51.
