Description

Technical Field

[0001] The present invention relates to an abnormality location identification system for identifying a location where an abnormality of a heat-sensitive wire occurs in a power supply device having a power supply line arranged along a moving path of a moving body and supplying power to the moving body and a heat-sensitive wire arranged along the power supply line. Background Art

[0002] An example of a power supply device such as the above is disclosed in Japanese Patent Application Laid-Open No. 10-201006 (Patent Document 1). In the following description of the background art, the symbols in Patent Document 1 are cited in parentheses. The power supply device disclosed in Patent Document 1 includes: an induction line (14) arranged along the moving path of the transport vehicle (V) to supply power to the transport vehicle (V); a heat-sensitive wire (15) arranged along the induction line (14); and a protection device (25). The protection device (25) includes a DC power supply (33) connected to a pair of conductors (17) constituting the heat-sensitive wire (15), and, as a means for detecting that the conductors (17) are short-circuited, includes a detection resistor (34) connected in series to the conductors (17) and an instrument relay (35) connected in parallel to the detection resistor (34). When the conductor (17) is short-circuited, the position of the short-circuited point of the conductor (17) is determined by checking the current value that changes according to the position of the short-circuited point of the conductor (17) through the meter relay (35). Summary of the invention

[0003] In the case of an abnormality such as a short circuit in a heat-sensitive wire, from the perspective of improving the work efficiency of the operator corresponding to the abnormality, it is ideal that the operator can easily grasp the estimated position of the abnormality generating part of the heat-sensitive wire on the wiring layout of the heat-sensitive wire. In this regard, in the technology described in Patent Document 1, the operator can grasp the distance along the heat-sensitive wire from the short-circuit point as the position of the short-circuit point in the heat-sensitive wire. However, most heat-sensitive wires are wired along complex paths, and it is difficult for the operator to grasp the position of the short-circuit point on the wiring layout of the heat-sensitive wire when only the distance to the short-circuit point is known, and the work efficiency of the operator for repairing the abnormality is easily reduced.

[0004] Therefore, it is desired to realize a technology that allows an operator to easily grasp the estimated position of the abnormality occurrence site where the abnormality occurred in the heat-sensitive wire on the wiring layout of the heat-sensitive wire when an abnormality occurs in the heat-sensitive wire.

[0005] The abnormality location determination system involved in the present disclosure is an abnormality location determination system for determining a location where an abnormality of a heat-sensitive line has occurred in a power supply device, the power supply device comprising a power supply line arranged along a moving path of a moving body and supplying power to the aforementioned moving body, a power supply device connected to the aforementioned power supply line and supplying power to the aforementioned power supply line, the aforementioned heat-sensitive line arranged along the aforementioned power supply line, and an abnormality detection device for detecting an abnormality of the aforementioned heat-sensitive line, the abnormality location determination system comprising: a display device that displays information; a control device that controls the aforementioned display device; and a storage device that stores map data of the aforementioned power supply device, wherein the aforementioned map data includes power supply configuration information showing the configuration of the aforementioned power supply device, power supply line configuration information showing the configuration of the aforementioned power supply line connected to the aforementioned power supply device, and and heat-sensitive wire configuration information showing the configuration of the heat-sensitive wires configured along the power supply line, the control device comprising a distance information acquisition unit and an abnormal part display processing unit, the distance information acquisition unit acquiring distance information showing the distance from the power supply device to the position where the abnormality of the heat-sensitive wires occurred when the abnormality of the heat-sensitive wires is detected by the abnormality detection device, the abnormal part display processing unit executing: abnormal part inference processing, which infers the position of the abnormal part where the abnormality of the heat-sensitive wires occurred based on the distance information; and display processing, which displays a map showing the configuration of the heat-sensitive wires on the display device based on the map data, and displays the inferred position of the abnormal part where the abnormality occurred inferred by the abnormal part inference processing on the map.

[0006] According to this configuration, when an abnormality of a heat-sensitive wire such as a short circuit or a broken wire is detected, the estimated location of the abnormality where the abnormality of the heat-sensitive wire occurred can be displayed on a map showing the configuration of the heat-sensitive wire displayed on the display device (i.e., on the wiring layout of the heat-sensitive wire). Therefore, the operator can easily grasp the estimated location of the abnormality on the wiring layout of the heat-sensitive wire based on the information displayed on the display device. Thus, for example, when the operator goes to the abnormality location for inspection or repair, the operator can easily grasp at which place in the power supply equipment the abnormality of the heat-sensitive wire occurred.

[0007] As described above, according to this configuration, an operator can easily grasp the estimated position of the abnormality occurrence site where the abnormality of the heat-sensitive wire has occurred on the wiring layout of the heat-sensitive wire.

[0008] Further features and advantages of the abnormality identification system will become apparent from the following description of the embodiments described with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] An embodiment of the abnormality location identification system will be described with reference to the drawings. The abnormality location identification system S is a system for identifying a location where an abnormality of the heat-sensitive wire 4 has occurred in the power supply facility 100 .

[0011] The power supply equipment 100 is a device for supplying power to the moving object 1 moving along the moving path 2. In the power supply equipment 100 of the present embodiment, the wireless power supply technology is used to supply power to the moving object 1 in a contactless manner.

[0012] Figure 1 An article transport device 200 is shown as an example of a device to which the power supply device 100 is applicable. Figure 1 In the example shown, the moving path 2 is formed in a manner that passes through a processing device 21 that processes an unillustrated article (or a content contained in the article), and the moving body 1 (here, an unmanned transport vehicle) moves along the moving path 2 to transport the article. For example, the article that becomes the processing object in the processing device 21 is transported into the processing device 21 by the moving body 1, and the article that has been processed in the processing device 21 is transported out of the processing device 21 by the moving body 1. The article is, for example, a FOUP (Front Opening Unified Pod) that accommodates semiconductor wafers.

[0013] The movement path 2 may be formed physically or virtually. Figure 3 In the embodiment, it is assumed that the moving path 2 is physically formed by the rails 20 (here, a pair of rails 20 arranged at intervals in the horizontal direction). When the moving path 2 is virtually formed, the moving path 2 is formed using, for example, a two-dimensional code or RF (Radio Frequency) tag set on the ground.

[0014] Figure 3The moving body 1 illustrated in the figure is constructed as follows. The moving body 1 includes a traveling portion 11 that travels along a moving path 2 (here, a track 20) ​​and a main body 10 connected to the traveling portion 11. Articles are transported by the moving body 1 in a state of being contained in the main body 10. The traveling portion 11 includes traveling wheels 13 that roll on a traveling surface (here, an upper surface) of the track 20 and a traveling drive portion 12 (for example, an electric motor such as a servo motor) that rotates the traveling wheels 13. The traveling wheels 13 are rotationally driven by the traveling drive portion 12, so that the traveling portion 11 travels along the track 20. The traveling portion 11 also includes guide wheels 14 that roll on a guide surface (here, a side surface) of the track 20, and the traveling portion 11 travels along the track 20 in a state where the guide wheels 14 are contacted and guided by the guide surface of the track 20.

[0015] exist Figure 3 In the example shown, the moving body 1 is a ceiling transport vehicle that travels along a track 20 suspended from the ceiling, but the type of the moving body 1 is not limited thereto. For example, the moving body 1 may be a rail-mounted vehicle that travels along a track provided on the ground, a traveling vehicle (shuttle vehicle) that travels along a track provided corresponding to a plurality of shelves for storing articles, a traveling vehicle of a stacking crane, or the like.

[0016] like Figure 2 and Figure 3 As shown, the power supply device 100 includes a power supply line 3 and a power supply device 5 connected to the power supply line 3. The power supply device 5 supplies power to the power supply line 3. The power supply device 5 is, for example, a power supply board in which a device for supplying power is installed. The power supply device 5 supplies AC current to the power supply line 3. The power supply device 5 includes a power supply circuit such as a switching power supply circuit having an inverter circuit. The power supply device 5 outputs AC current to the power supply circuit by, for example, pulse width modulation (PWM: Pulse Width Modulation).

[0017] The power supply line 3 is arranged along the moving path 2 of the moving body 1. Figure 3 In the example shown, the power supply line 3 is arranged along the track 20 forming the moving path 2. And, the power supply line 3 supplies electric power to the moving body 1. The method of supplying electric power from the power supply line 3 to the moving body 1 may be either a non-contact method or a contact method. For example, in the non-contact method, electric power is supplied to the moving body 1 from the power supply line 3 as an induction line, and in the contact method, electric power is supplied to the moving body 1 from the power supply line 3 as a trolley line. In this embodiment, the method of supplying electric power from the power supply line 3 to the moving body 1 is a non-contact method. That is, the power supply line 3 supplies electric power to the moving body 1 in a non-contact manner. As Figure 3 As shown in FIG. 1 , the power supply line 3 includes a conductor wire body 3a (core wire) formed of a conductor and a sheath 3b formed of an insulator and covering the conductor wire body 3a. Figure 3In the example, the power supply line 3 is shown to have a conductor wire having a conductor wire body 3a and a coating 3b, but the power supply line 3 can also be configured as follows: it has a conductor wire bundle and an insulating coating covering the periphery of the conductor wire bundle, and the conductor wire bundle is formed by bundling multiple conductor wires having a conductor wire body 3a and a coating 3b.

[0018] The mobile body 1 includes a power receiving device 15 that receives power from the power supply line 3. In the present embodiment, the power receiving device 15 receives power from the power supply line 3 in a non-contact manner. Figure 3 or later reference Figure 6 As shown, in this embodiment, two power supply lines 3 are arranged along the movement path 2, and the power receiving device 15 is arranged between the two power supply lines 3 and receives power supply from the two power supply lines 3 in a non-contact manner. Figure 3 In the illustrated example, one power supply line 3 is arranged along one of the pair of rails 20 , and another power supply line 3 is arranged along the other of the pair of rails 20 .

[0019] As in Figure 2 As shown in the simplified form in FIG. 2 , the power supply line 3 and the heat-sensitive wire 4 described later are arranged so as to extend from the power supply device 5, extend along the moving path 2, and return to the power supply device 5 (in other words, the same power supply device 5). That is, the power supply line 3 and the heat-sensitive wire 4 are arranged so as to form a closed loop. As described above, in this embodiment, two power supply lines 3 are arranged along the moving path 2, but these two power supply lines 3 constitute the same closed loop.

[0020] One closed loop may be formed by one continuous power supply line 3 or by a plurality of power supply lines 3 connected to each other via a connection portion such as a connector or a terminal block. Similarly, one closed loop may be formed by one continuous heat-sensitive wire 4 or by a plurality of heat-sensitive wires 4 connected to each other via a connection portion such as a connector or a terminal block. In addition, each of the portions of one continuous power supply line 3 having different extension directions (extension directions of the power supply line 3) may be regarded as one power supply line 3. For example, in the present embodiment, as described above, two power supply lines 3 are arranged along the moving path 2, but these two power supply lines 3 may be two power supply lines 3 connected to each other via a connection portion, or may be two power supply lines 3 in the case where each of the portions of one continuous power supply line 3 having different extension directions is regarded as one power supply line 3. Similarly, each of the portions of one continuous heat-sensitive wire 4 having different extension directions (extension directions of the heat-sensitive wire 4) may be regarded as one heat-sensitive wire 4.

[0021] The power received by the power receiving device 15 is used to perform at least a part of the movement of the moving body 1 (for example, the movement along the moving path 2). That is, the power received by the power receiving device 15 is supplied to an actuator (for example, the above-mentioned travel drive unit 12) for causing the moving body 1 to move. The power receiving device 15 includes, for example, a pickup coil. The magnetic field generated around the power supply line 3 supplied with the alternating current induces alternating current power in the pickup coil. The alternating current power is converted into direct current, for example, and supplied to the actuator for causing the moving body 1 to move.

[0022] like Figure 2 As shown, in the present embodiment, the power supply device 100 includes a plurality of power supply units, which are a set of a power supply line 3 and a power supply device 5 connected to the power supply line 3. That is, the power supply device 100 includes a plurality of power supply lines 3 and a power supply device 5 connected to each of the plurality of power supply lines 3. Here, the so-called "plurality of power supply lines 3" means that when a power supply line 3 that is arranged so as to extend from the power supply device 5 and extend along the moving path 2 and return to the power supply device 5 is regarded as one power supply line 3, there are a plurality of such power supply lines 3.

[0023] Each of the plurality of power supply units supplies power to the mobile object 1 in the power supply area for which it is responsible. The two power supply devices 5 that are different from each other are the first power supply device 51 and the second power supply device 52. Figure 6 In the example, the area where the power supply line 3 connected to the first power supply device 51 is arranged (but excluding the portion between the first power supply device 51 and the junction box T described later) is a power supply area supplied with power from the first power supply device 51, and the area where the power supply line 3 connected to the second power supply device 52 is arranged (but excluding the portion between the second power supply device 52 and the junction box T described later) is a power supply area supplied with power from the second power supply device 52. Although details are omitted, in order to enable the mobile body 1 to receive power supply in the transfer section between the power supply areas, the plurality of power supply devices 5 are controlled in such a manner that the phases of the alternating currents of the two power supply lines 3 arranged in the transfer section are consistent.

[0024] The power supply device 100 includes a heat-sensitive wire 4 arranged along the power supply line 3 in addition to the power supply line 3. The heat-sensitive wire 4 is arranged so as to extend along the movement path 2 together with the power supply line 3. In the present embodiment, the power supply device 100 includes a plurality of power supply lines 3, and the heat-sensitive wire 4 is arranged along each of the plurality of power supply lines 3.

[0025] like Figure 3As shown, the heat-sensitive wire 4 includes a first conductor 41 and a second conductor 42 as a pair of conductors. Each of the first conductor 41 and the second conductor 42 is a coated conductor wire in which a core wire 4a formed of a conductor is coated with an insulator 4b that softens at a predetermined temperature. Furthermore, the heat-sensitive wire 4 is formed by twisting the first conductor 41 and the second conductor 42, which are a pair of conductors, into a so-called twisted pair of twisted wires by further coating them with a coating material 4c. The heat-sensitive wire 4 is configured such that if the insulator 4b softens, the core wire 4a of the first conductor 41 and the core wire 4a of the second conductor 42 come into contact and short-circuit. In addition, even if the insulator 4b softens, the core wire 4a is suppressed from being exposed to the outside because the first conductor 41 and the second conductor 42 are coated with the coating material 4c.

[0026] The heat-sensitive wire 4 is arranged along the power supply line 3 so as to detect abnormal heating of the power supply line 3 or its surroundings. Figure 3 In the example shown, the heat-sensitive wire 4 is arranged at a position adjacent to the power supply wire 3 (here, at a position in contact with the power supply wire 3 from the outside). In addition, when the power supply wire 3 includes a conductor wire bundle and an insulating sheath covering the periphery of the conductor wire bundle as described above, the heat-sensitive wire 4 may be arranged inside the insulating sheath. In this case, the heat-sensitive wire 4 is arranged at the center of the power supply wire 3 in a manner surrounded by a plurality of conductor wires constituting the conductor wire bundle, for example.

[0027] The power supply device 100 includes an abnormality detection device 6 for detecting an abnormality of the heat-sensitive wire 4. When the abnormality detection device 6 detects an abnormality of the heat-sensitive wire 4, for example, a control device 7 described later performs an abnormality control corresponding to the abnormality of the heat-sensitive wire 4. The abnormality control is, for example, a control to stop the power supply of the power supply device 5 to the power supply line 3.

[0028] The abnormality of the heat-sensitive wire 4 detected by the abnormality detection device 6 includes a short circuit of the heat-sensitive wire 4 caused by heat. For example, the heat-sensitive wire 4 is short-circuited due to abnormal heat of the power supply line 3 or its periphery. As a cause of abnormal heat generation of the power supply line 3, for example, the temperature of the power supply line 3 rises due to an overcurrent or a short circuit caused by an overload. In addition, as a cause of abnormal heat generation around the power supply line 3, for example, the temperature of the metal (for example, a metal tool left by an operator by mistake) existing around the power supply line 3 rises due to the influence of the magnetic field generated around the power supply line 3. It is also possible to set it as follows: Among the abnormalities of the heat-sensitive wire 4 detected by the abnormality detection device 6, in addition to the short circuit of the heat-sensitive wire 4, the disconnection of the heat-sensitive wire 4 caused by poor installation or aging, etc.

[0029] like Figure 4 As shown, in this embodiment, the abnormality detection device 6 is provided in the power supply device 5. Specifically, as Figure 5As shown, the abnormality detection device 6 includes a first substrate 61 built into the power supply device 5. The first substrate 61 is a heat-sensitive wire substrate for detecting abnormalities of the heat-sensitive wire 4. The abnormality detection device 6 also includes a second substrate 62 built into the power supply device 5. The second substrate 62 is an abnormality occurrence location identification substrate for identifying an abnormality occurrence location 9 where the abnormality of the heat-sensitive wire 4 has occurred.

[0030] The connection state between the abnormality detection device 6 and the heat-sensitive wire 4 is switched to a first connection state (in which the first substrate 61 and the heat-sensitive wire 4 are connected) by a switching device 60 such as a relay. Figure 5 The state shown by the solid line in FIG. 1 ) and the second connection state in which the second substrate 62 is connected to the heat-sensitive wire 4 (in FIG. 1 ). Figure 5 The connection state between the abnormality detection device 6 and the heat-sensitive wire 4 is normally set to the first connection state, and is switched to the second connection state when the abnormality detection device 6 (specifically, the first substrate 61) detects an abnormality in the heat-sensitive wire 4.

[0031] exist Figure 5 In the example shown, the first substrate 61 includes a signal output unit 6c, a first detection circuit 6a, and a second detection circuit 6b. In the first connection state described above, one end of the heat-sensitive wire 4 is connected to the signal output unit 6c and the first detection circuit 6a, and the other end of the heat-sensitive wire 4 is connected to the second detection circuit 6b. Specifically, one end of the first conductive wire 41 is connected to the signal output unit 6c, one end of the second conductive wire 42 is connected to the first detection circuit 6a, and the other end of the first conductive wire 41 and the other end of the second conductive wire 42 are connected to the second detection circuit 6b.

[0032] The signal output unit 6c includes a circuit (e.g., a DC / DC converter) constituting a power supply, and supplies power to the first conductive wire 41 and the second conductive wire 42. The first detection circuit 6a monitors the current flowing through the portion on the one end side of the second conductive wire 42. The second detection circuit 6b monitors the current flowing through the connection portion between the other end of the first conductive wire 41 and the other end of the second conductive wire 42. The first detection circuit 6a and the second detection circuit 6b include, for example, a mechanical relay having a coil and contacts. The first detection circuit 6a and the second detection circuit 6b determine that a signal is detected when a current (e.g., a current sufficient to close the contacts of the relay, the same applies below) flows through the monitoring target portion of each current, and determine that a signal is not detected when a current does not flow through the monitoring target portion of each current.

[0033] When the heat-sensitive wire 4 is normal, it is determined that a signal is detected in both the first detection circuit 6a and the second detection circuit 6b. On the other hand, when a short circuit occurs in the heat-sensitive wire 4, it is determined that a signal is detected in the first detection circuit 6a, but it is determined that a signal is not detected in the second detection circuit 6b. In the case where a break occurs at the other end side of the heat-sensitive wire 4 (the side connected to the second detection circuit 6b) closer to the short-circuit location, the same determination is made. In addition, when a break occurs in the heat-sensitive wire 4, it is determined that a signal is not detected in both the first detection circuit 6a and the second detection circuit 6b. In the case where a short circuit occurs at the other end side of the heat-sensitive wire 4 closer to the short-circuit location, the same determination is made.

[0034] The abnormality detection device 6 (specifically, the operation processing device included in the abnormality detection device 6) determines that an abnormality (specifically, a short circuit) has occurred in the heat-sensitive wire 4 when the state in which the signal is detected in both the first detection circuit 6a and the second detection circuit 6b changes to the state in which the signal is detected in the first detection circuit 6a and the signal is not detected in the second detection circuit 6b. In addition, the abnormality detection device 6 determines that an abnormality (specifically, a break) has occurred in the heat-sensitive wire 4 when the state in which the signal is detected in both the first detection circuit 6a and the second detection circuit 6b changes to the state in which the signal is not detected in both the first detection circuit 6a and the second detection circuit 6b.

[0035] In addition, the first substrate 61 may be configured not to include the first detection circuit 6a. In this case, when the state where the second detection circuit 6b detects a signal changes to the state where the second detection circuit 6b does not detect a signal, the abnormality detection device 6 determines that an abnormality has occurred in the heat-sensitive wire 4. The abnormality of the heat-sensitive wire 4 is detected without distinguishing between a short circuit and a disconnection.

[0036] exist Figure 5 In the example shown, the second substrate 62 includes a reference voltage generating unit 6d, a voltage detecting unit 6e, and a resistor 6f. In the second connection state described above, one end of the first wire 41 is connected to the reference voltage generating unit 6d via the resistor 6f, one end of the second wire 42 is grounded, and the other end of the first wire 41 is connected to the other end of the second wire 42. The voltage detecting unit 6e detects the voltage between the resistor 6f and one end of the first wire 41.

[0037] The reference voltage generated by the reference voltage generating unit 6d is divided by the resistor 6f and the conductor resistance of the heat-sensitive wire 4. Here, the conductor resistance of the heat-sensitive wire 4 changes in accordance with the abnormality generating part 9 (specifically, the generating part of the short circuit). Specifically, the conductor resistance of the heat-sensitive wire 4 increases as the distance between one end of the heat-sensitive wire 4 (the end connected to the reference voltage generating unit 6d) and the abnormality generating part 9 increases. Therefore, the distance from the abnormality detecting device 6 to the abnormality generating part 9 (in this embodiment, the same as the distance from the power supply device 5 to the abnormality generating part 9) can be estimated based on the detection value of the reference voltage by the voltage detecting unit 6e. In this way, the abnormality detecting device 6 estimates the distance to the abnormality generating part 9 by using the fact that the conductor resistance of the heat-sensitive wire 4 changes in accordance with the abnormality generating part 9 (specifically, the generating part of the short circuit). In addition, the estimation method of the distance to the abnormality generating part 9 shown here is an example, and other estimation methods can also be adopted.

[0038] Next, the structure of the abnormal part identification system S according to this embodiment will be described. Figure 4 As shown, the abnormal part determination system S includes: a display device 80 that displays information; a control device 7 that controls the display device 80; and a storage device 82 that stores map data 83 of the power supply device 100. In this embodiment, the control device 7 also controls the power supply device 5. In addition, the control device 7 may also be a device different from the device that controls the power supply device 5. In this case, the control device 7 may not be configured in a manner that can communicate with the power supply device 5. The abnormal part determination system S also includes an input device 84. Each function of the control device 7 is realized by the cooperation of hardware such as a computing processing device and a program executed on the hardware.

[0039] Figure 4 The devices shown are at least conceptually distinguished, and two or more devices (for example, the control device 7 and the power supply device 5) may be provided in a common device, and one device may be a collection of multiple devices. In addition, the functional units of the control device 7 are at least logically distinguished, but they do not necessarily have to be physically distinguished. In addition, at least part of the functions of the abnormality detection device 6 (for example, the function of determining the abnormality of the heat-sensitive wire 4 or the function of inferring the distance from the abnormality occurrence site 9) can also be implemented by the control device 7.

[0040] The control device 7 generates a display screen 81 (see Figures 6 to 8 ) to display a display image, and controls the display device 80 so that the display image is displayed on the display screen 81. As the display device 80, a liquid crystal display or an organic EL (Electro Luminescence) display can be exemplified. Figures 6 to 8In the example, the display screen 81 is provided on the outer surface of the display device 80, but the display screen 81 may be a screen projected onto a screen or the like.

[0041] The control device 7 obtains operation information indicating the content of the operation (e.g., numerical input operation or screen operation, etc.) performed by the operator or the like on the input device 84. The control device 7, for example, generates a display image corresponding to the content of the screen operation. As the input device 84, a keyboard or a pointing device (mouse, touch pad, touch panel, etc.) can be exemplified. In addition, the display device 80 can also be a device in which the input device 84 is integrated, such as a device in which the display screen 81 functions as a touch panel.

[0042] The storage device 82 includes a storage medium capable of storing and rewriting information. The control device 7 refers to the storage device 82 to obtain information stored in the storage device 82 (for example, information included in the map data 83). As the storage device 82, a flash memory or a hard disk drive can be exemplified. The storage device 82 can also be provided in a server or a cloud server capable of communicating with the control device 7.

[0043] The map data 83 stored in the storage device 82 includes power configuration information showing the configuration of the power supply device 5, power supply line configuration information showing the configuration of the power supply line 3 connected to the power supply device 5, and heat-sensitive line configuration information showing the configuration of the heat-sensitive line 4 arranged along the power supply line 3. The map data 83 may also include other information necessary for displaying the map M described later. As other information, information on the layout of the moving path 2 or information on the address (address number) set on the moving path 2 can be exemplified.

[0044] In the present embodiment, the power supply device 100 includes a plurality of power supply lines 3 and a plurality of power supply devices 5. Therefore, the power supply configuration information included in the map data 83 is information showing the configuration of the plurality of power supply devices 5, the power supply line configuration information included in the map data 83 is information showing the configuration of the power supply lines 3 connected to each of the plurality of power supply devices 5, and the heat-sensitive line configuration information is information showing the configuration of the heat-sensitive lines 4 arranged along each of the plurality of power supply lines 3.

[0045] The control device 7 includes a distance information acquisition unit 71 and an abnormal part display processing unit 72. In the present embodiment, the control device 7 further includes a power source identification information acquisition unit 70.

[0046] The distance information acquisition unit 71 is a functional unit that acquires distance information indicating the distance from the power supply device 5 (specifically, the target power supply device described later) to the position where the abnormality of the heat-sensitive wire 4 has occurred when the abnormality detection device 6 detects the abnormality of the heat-sensitive wire 4. In the present embodiment, the distance information acquisition unit 71 acquires the value of the distance input by the operator using the input device 84 as the distance information. For example, the value of the distance to the abnormality occurrence position 9 estimated by the abnormality detection device 6 (specifically, the second substrate 62) is displayed on the display unit of the power supply device 5, and the operator inputs the displayed value using the input device 84. In this case, for example, if it is configured so that when the abnormality of the power supply device 5 occurs, zero is displayed as the value of the distance on the display unit of the power supply device 5, it is easy to distinguish between the abnormality of the heat-sensitive wire 4 and the abnormality of the power supply device 5. In addition, instead of the configuration in which the operator inputs the distance value as described above, it is also possible to set the configuration as follows: the distance information acquisition unit 71 communicates with the abnormality detection device 6 or the power supply device 5 through the control device 7, and obtains the value of the distance to the abnormality occurrence site 9 inferred by the abnormality detection device 6 as distance information.

[0047] In a case where the abnormality detection device 6 is arranged at a position different from the power supply device 5, etc., and in a case where the distance value input to the control device 7 by the operator or through communication is the value of the distance from a reference position different from the power supply device 5 to the abnormality occurrence position 9, the distance information acquisition unit 71 obtains the value of the distance from the power supply device 5 to the abnormality occurrence position 9 by performing an operation based on the distance value input to the control device 7 (for example, the sum of the distance values ​​between the power supply device 5 and the reference position).

[0048] The power source identification information acquisition unit 70 is a functional unit that acquires power source identification information that identifies the target power source device as the power source device 5 connected to the power supply line 3 along which the abnormal heat-sensitive wire 4 runs. In the present embodiment, the operator specifies the power source device 5 using the input device 84, and the power source identification information acquisition unit 70 acquires information that identifies the power source device 5 specified by the operator as the power source identification information. For example, the operator specifies the power source device 5 connected to the power supply line 3 along which the abnormal heat-sensitive wire 4 runs (in other words, the power source device 5 to which the abnormal heat-sensitive wire 4 is connected) by abnormality notification using a warning sound or a warning light, a screen display, etc., and specifies the specified power source device 5 using the input device 84. The operator specifies the power source device 5 by, for example, selecting the power source device 5 by a click operation or inputting a number that specifies the power source device 5 on the map M described later. In addition, instead of such a configuration, for example, the power source identification information acquisition unit 70 may acquire the power source identification information through communication between the control device 7 and the abnormality detection device 6 or the power source device 5.

[0049] The abnormal part display processing unit 72 is a functional unit that performs abnormal part estimation processing and display processing. The abnormal part estimation processing is a processing for estimating the position of the abnormal part 9 where the abnormality of the heat-sensitive line 4 occurs based on the distance information. In the present embodiment, in the abnormal part estimation processing, the position of the abnormal part 9 is estimated based on the distance information and the power source determination information. The display processing is a processing in which the map M showing the arrangement of the heat-sensitive line 4 is displayed on the display device 80 based on the map data 83, and the estimated position E of the abnormal part 9 estimated by the abnormal part estimation processing is displayed on the map M.

[0050] Figure 6 FIG. 8 shows a case where the map M is displayed on the display screen 81 through display processing. Figure 6 , the layout of the moving path 2 is shown (see Figure 1 ). In the map M, the moving path 2, the power supply line 3, the power supply device 5, the junction box T described later, and the address of the moving path 2 (here, a numerical value such as "0000"). Here, two power supply devices 5, namely the first power supply device 51 and the second power supply device 52, the power supply line 3 connected to the first power supply device 51, the heat-sensitive wire 4 arranged along the power supply line 3 (the heat-sensitive wire 4 connected to the first power supply device 51), the power supply line 3 connected to the second power supply device 52, and the heat-sensitive wire 4 arranged along the power supply line 3 (the heat-sensitive wire 4 connected to the second power supply device 52) are displayed. In addition, for example, the power supply device 5, the portion between the power supply device 5 and the junction box T in the power supply line 3, the portion between the power supply device 5 and the junction box T in the heat-sensitive wire 4, etc., can also be displayed in a place different from the actual one on the map M in consideration of easy observation.

[0051] As in Figure 2 As shown in the simplified form in FIG. 1 , in the present embodiment, the power supply line 3 and the heat-sensitive line 4 are arranged in a manner to form a circumferential path P extending from the power supply device 5 and returning to the power supply device 5 (in other words, the same power supply device 5). Here, one side of the circumferential direction C of the circumferential path P is set as the first side C1, and the side opposite to the first side C1 is set as the second side C2. In the present embodiment, the power supply device 100 has a junction box T, and the first part of the power supply line 3 extending from the power supply device 5 to the first side C1 to the junction box T and the second part of the power supply line 3 extending from the power supply device 5 to the second side C2 to the junction box T are arranged adjacent to each other so as to make it difficult to generate a magnetic field in the surroundings (in other words, to form a non-inductive line). Therefore, in Figure 6 In the example shown, the portion of the power supply line 3 between the power supply device 5 and the junction box T is represented by one line segment. Figure 6 In the illustrated example, the portion of the heat-sensitive line 4 between the power supply device 5 and the junction box T is also represented by a single line segment.

[0052] In the abnormal part inference processing, the abnormal part display processing unit 72 infers the position of the distance indicated by the distance information (the distance information acquired by the distance information acquisition unit 71) that has advanced from the power supply device 5 (specifically, the target power supply device, the same below) along the heat-sensitive line 4 as the position of the abnormal part 9. Specifically, in the abnormal part inference processing, the abnormal part display processing unit 72 infers the first position E1 that has advanced from the power supply device 5 along the surrounding path P (the surrounding path P formed by the heat-sensitive line 4, the same below) to the first side C1 by the distance indicated by the distance information and the second position E2 that has advanced from the power supply device 5 along the surrounding path P to the second side C2 by the distance indicated by the distance information as the position of the abnormal part 9. Furthermore, as Figure 7 As shown, the abnormality location display processing unit 72 displays both the first position E1 and the second position E2 as the estimated position E of the abnormality occurrence location 9 on the map M during the display processing. Figure 7 In, with Figure 6 Differently, the power supply line 3 is not shown.

[0053] exist Figure 7 In the example, it is assumed that the target power supply device (power supply device 5 connected to the power supply line 3 along which the abnormal heat-sensitive line 4 is running) is the first power supply device 51. Figure 7 In the figure, two estimated positions E, namely, a first position E1 which has advanced from the first power supply device 51 along the circumferential path P to the first side C1 by a distance indicated by the distance information, and a second position E2 which has advanced from the first power supply device 51 along the circumferential path P to the second side C2 by a distance indicated by the distance information, are displayed on the map M. Here, the estimated positions E are indicated by double circular marks.

[0054] Here, it is appropriate that the abnormal part display processing unit 72 is configured as follows: in the display processing, the configuration path of the heat-sensitive line 4 from the power supply device 5 (specifically, the target power supply device) to the estimated position E of the abnormal occurrence part 9 is emphasized and displayed in comparison with the configuration paths of the heat-sensitive line 4 of other parts. For example, by making the color (hue, brightness, etc.) different, the thickness different, the shape (solid line, dotted line, single-point dash line, etc.) different, or a combination thereof, the configuration path of the heat-sensitive line 4 from the power supply device 5 to the estimated position E of the abnormal occurrence part 9 can be emphasized and displayed in comparison with the configuration paths of the heat-sensitive line 4 of other parts. Figure 7 In the example shown, as indicated by the symbol "H", both the arrangement path of the heat-sensitive wire 4 from the first power supply device 51 to the first position E1 and the arrangement path of the heat-sensitive wire 4 from the first power supply device 51 to the second position E2 are made thicker than the arrangement path of the heat-sensitive wire 4 in other parts. Figure 7In the embodiment, both the first position E1 and the second position E2 are set as the objects to be highlighted, but only one of the first position E1 and the second position E2 (for example, the one selected by the operator) may be set as the object to be highlighted.

[0055] For example, if the abnormal part determination system S is constructed as follows, it is easy to determine the configuration path of the heat-sensitive line 4 from the power supply device 5 to the estimated position E of the abnormal part 9. The control device 7 is configured to be able to accept an abnormal part display operation for displaying the abnormal part 9. Moreover, in a state where the abnormal part display processing unit 72 does not accept the abnormal part display operation, in the display processing, both the power supply device 5 (specifically, the target power supply device, the same below) and the estimated position E of the abnormal part 9 are displayed on the map M, or the entire path of the heat-sensitive line 4 from the power supply device 5 to the estimated position E of the abnormal part 9 is displayed on the map M. Figure 7 In the illustrated example, the entire path of the heat-sensitive line 4 from the power supply device 5 to the estimated position E (here, both the first position E1 and the second position E2 ) of the abnormality occurrence site 9 is displayed on the map M.

[0056] Furthermore, when the abnormal part display processing unit 72 has accepted the abnormal part display operation, in the display processing, the map M of the surrounding area of ​​the estimated position E of the abnormal part 9 is displayed on the display device 80. Specifically, when the operation of selecting the first position E1 (for example, a click operation using the input device 84) has been accepted as the abnormal part display operation, the map M of the surrounding area of ​​the first position E1 is displayed, and when the operation of selecting the second position E2 has been accepted as the abnormal part display operation, the map M of the surrounding area of ​​the first position E1 is displayed. Figure 8 (d) shows a map M of the vicinity of the second position E2. Here, when the map M of the vicinity of the estimated position E of the abnormality occurrence site 9 is displayed on the display device 80, the map M is displayed as shown in FIG. Figure 8 As in the example shown in (d), it is appropriate to compare the normal display processing (the state where the abnormal part display operation is not accepted, refer to Figure 7 ) is compared to the above, and the periphery of the estimated position E of the abnormality occurrence site 9 is displayed enlarged.

[0057] In addition, even if the abnormal part determination system S is constructed as follows in addition to or instead of the above-mentioned construction, it is easy to determine the configuration path of the heat-sensitive line 4 from the power supply device 5 to the estimated position E of the abnormal part 9. The control device 7 is constructed so as to be able to accept an animation playback request operation. The animation playback request operation is, for example, set to a click operation on a button image representing "animation playback" using the input device 84. Moreover, when the animation playback request operation has been accepted, the abnormal part display processing unit 72 performs the following animation playback processing in the display processing: the reference position A of the map M displayed on the display device 80 is moved along the configuration path of the heat-sensitive line 4 from the power supply device 5 (specifically, the target power supply device) to the estimated position E of the abnormal part 9, and the map M is displayed at the same time. Figure 8 In Figure 8 (a) Figure 8 (b) Figure 8 (c) Figure 8 (d) shows in chronological order that the second position E2 (refer to Figure 7 ) is a map M displayed when an operation is requested to reproduce the animation of the object. Here, the reference position A is indicated by a double-circle mark which is the same as the estimated position E.

[0058] exist Figure 8 (a) to Figure 8 In the example shown in (d), the map M is displayed in a manner that the reference position A is arranged at the center position of the display area of ​​the map M (here, the entire area of ​​the display screen 81). In addition, the map M may be displayed in a manner that the reference position A is arranged at a position different from the center position of the display area of ​​the map M. For example, in a case where there is no object to be displayed (display object) on either side due to reasons such as being close to the end of the layout of the moving path 2, the map M may be displayed in a manner that the reference position A is arranged on the side where there is no display object relative to the center position of the display area of ​​the map M. In this case, the map M can be displayed in a manner that the display area on the side opposite to the side where there is no display object is widened.

[0059] [Other implementation methods] (1) In the above-mentioned embodiment, the following configuration is used as an example for explanation: in the abnormal part inference processing, the abnormal part display processing unit 72 infers the first position E1, which is the position that has advanced the distance indicated by the distance information from the power supply device 5 along the circumferential path P to the first side C1, and the second position E2, which is the position that has advanced the distance indicated by the distance information from the power supply device 5 along the circumferential path P to the second side C2, as the position of the abnormal part 9. However, the present disclosure is not limited to such a configuration, and may also be configured as follows: in a case where the inferred position E can be narrowed down to either the first position E1 or the second position E2, only either the first position E1 or the second position E2 is inferred as the position of the abnormal part 9. For example, in a case where the inferred position E can be narrowed down to either the first position E1 or the second position E2, the abnormal part 9 can be inferred from the second substrate 62 (specifically, the reference voltage generating unit 6d, refer to Figure 5 ) is determined as the first side C1 along the circumferential path P, only the first position E1 can be inferred as the position of the abnormality occurrence part 9. In addition, for example, when the side away from the connection part with the second substrate 62 along the circumferential path P can be determined as the second side C2, only the second position E2 can be inferred as the position of the abnormality occurrence part 9.

[0060] (2) In the above-mentioned embodiment, the following configuration is described as an example: the power supply device 100 includes a plurality of power supply units, and the power supply unit is a group of the power supply line 3 and the power supply device 5 connected to the power supply line 3. However, the present disclosure is not limited to such a configuration, and the power supply device 100 may also include only one power supply unit. In this case, unlike the above-mentioned embodiment, it is not necessary to provide the power source determination information acquisition unit 70 in the control device 7.

[0061] (3) In addition, as long as no contradiction is generated, the configuration disclosed in each of the above-mentioned embodiments can also be combined with the configuration disclosed in other embodiments and applied (including the combination of the embodiments described as other embodiments). With regard to other configurations, the embodiments disclosed in this specification are merely illustrative in all aspects. Therefore, various changes can be appropriately made without departing from the scope of the present disclosure.

[0062] [Summary of this embodiment] Hereinafter, an overview of the abnormal part identifying system described above will be described.

[0063] An abnormality location determination system is an abnormality location determination system for determining a location where an abnormality of a heat-sensitive line has occurred in a power supply device, the power supply device comprising a power supply line arranged along a moving path of a moving body and supplying power to the moving body, a power supply device connected to the power supply line and supplying power to the power supply line, the heat-sensitive line arranged along the power supply line, and an abnormality detection device for detecting an abnormality of the heat-sensitive line, the abnormality location determination system comprising: a display device for displaying information; a control device for controlling the display device; and a storage device for storing map data of the power supply device, wherein the map data includes power supply configuration information showing the configuration of the power supply device, power supply line configuration information showing the configuration of the power supply line connected to the power supply device, and an abnormality detection device for detecting an abnormality of the heat-sensitive line. The control device is provided with a distance information acquisition unit and an abnormal part display processing unit. When the abnormality of the heat-sensitive wire is detected by the abnormality detection device, the distance information acquisition unit acquires distance information showing the distance from the power supply device to the position where the abnormality of the heat-sensitive wire occurs. The abnormal part display processing unit performs: abnormal part inference processing, which infers the position of the abnormal part where the abnormality of the heat-sensitive wire occurs based on the distance information; and display processing, which displays a map showing the configuration of the heat-sensitive wire on the display device based on the map data, and displays the inferred position of the abnormal part inferred by the abnormal part inference processing on the map.

[0064] According to this configuration, when an abnormality of a heat-sensitive wire such as a short circuit or a broken wire is detected, the estimated location of the abnormality where the abnormality of the heat-sensitive wire occurred can be displayed on a map showing the configuration of the heat-sensitive wire displayed on the display device (i.e., on the wiring layout of the heat-sensitive wire). Therefore, the operator can easily grasp the estimated location of the abnormality on the wiring layout of the heat-sensitive wire based on the information displayed on the display device. Thus, for example, when the operator goes to the abnormality location for inspection or repair, the operator can easily grasp at which place in the power supply equipment the abnormality of the heat-sensitive wire occurred.

[0065] As described above, according to this configuration, an operator can easily grasp the estimated position of the abnormality occurrence site where the abnormality of the heat-sensitive wire has occurred on the wiring layout of the heat-sensitive wire.

[0066] Here, it is appropriate that the power supply line and the heat-sensitive line are arranged in a manner of extending from the power supply device, extending along the moving path and returning to the power supply device, and the abnormal part display processing unit infers the position of the power supply device along the heat-sensitive line for a distance indicated by the distance information as the position of the abnormal occurrence site in the abnormal part inference processing.

[0067] According to this configuration, when an abnormality in the heat-sensitive rays is detected, the estimated position of the abnormality occurrence site displayed on the display device can be estimated with high accuracy.

[0068] In the configuration for inferring the position of the abnormality occurrence site as described above, it is appropriate that the heat-sensitive wire is configured in a manner of forming a circumferential path extending from the power supply device and returning to the power supply device, one side of the circumferential direction of the circumferential path is set as the first side, and the side opposite to the first side is set as the second side, and the abnormality location display processing unit performs the following processing: in the abnormality location inference processing, the first position, which is the position that has advanced from the power supply device along the circumferential path to the first side by the distance indicated by the distance information, and the second position, which is the position that has advanced from the power supply device along the circumferential path to the second side by the distance indicated by the distance information, are inferred as the positions of the abnormality occurrence site, and in the display processing, both the first position and the second position are displayed on the map as the inferred positions of the abnormality occurrence site.

[0069] According to this configuration, when the heat-sensitive wires are arranged in a manner to form a circular path, considering that there are basically two positions that have traveled the same distance from the power supply device along the heat-sensitive wires, two positions that are candidates for the estimated positions of the abnormality occurring on the wiring layout of the heat-sensitive wires can be displayed on the display device.

[0070] In the abnormal part determination system of each of the above-mentioned structures, it is suitable that the control device is capable of accepting an abnormal part display operation for displaying the abnormal part, and the abnormal part display processing unit performs the following processing: in a state where the abnormal part display operation is not accepted, in the above-mentioned display processing, both the power supply device and the estimated position of the abnormal part are displayed on the above-mentioned map, or the entire path of the heat-sensitive line from the above-mentioned power supply device to the estimated position of the above-mentioned abnormal part is displayed on the above-mentioned map; in a state where the abnormal part display operation is accepted, in the above-mentioned display processing, the above-mentioned map of the surrounding area of ​​the estimated position of the above-mentioned abnormal part is displayed on the above-mentioned display device.

[0071] According to this configuration, the operator can easily grasp the positional relationship between the power supply device and the estimated position of the abnormality occurrence location when both the power supply device and the estimated position of the abnormality occurrence location are displayed on the map, or when the entire path of the heat-sensing line from the power supply device to the estimated position of the abnormality occurrence location is displayed on the map. In addition, the operator performs the abnormality location display operation to display a map of the surrounding area of ​​the estimated position of the abnormality occurrence location on the display device, thereby easily grasping the structure of the power supply equipment in the vicinity of the abnormality occurrence location.

[0072] Preferably, in the display process, the abnormality location display processing unit displays an arrangement path of the heat-sensitive line from the power supply device to the estimated position of the abnormality occurrence location in an emphasized manner compared with arrangement paths of the heat-sensitive line in other portions.

[0073] According to this configuration, information that makes it easy to identify the arrangement path of the heat-sensitive line from the power supply device to the estimated position of the abnormality occurrence site can be displayed on the display device.

[0074] In addition, it is suitable that the control device is configured to accept an animation reproduction request operation, and when the abnormal part display processing unit has accepted the animation reproduction request operation, in the display processing, the reference position of the map displayed on the display device is moved along the configuration path of the thermal line from the power supply device to the estimated position of the abnormality occurrence site and the animation reproduction processing of the map is simultaneously displayed.

[0075] According to this configuration, information that makes it easy to identify not only the shape but also the direction of the arrangement path of the heat-sensitive line from the power supply device to the estimated position of the abnormality occurrence site can be displayed on the display device.

[0076] The abnormal part identification system according to the present disclosure only needs to achieve at least one of the above-mentioned effects.
