Description

  The present invention relates to an on-vehicle test apparatus and an on-vehicle test method for automatically inspecting equipment mounted on a train.

  In recent years, the needs of customers such as high-speed transportation and improvement of riding comfort are increasing in railway vehicles, and many devices such as ATS (Automatic Train Stop) are installed as means for meeting such needs. On the other hand, the configuration of these devices is complicated, and the inspection is also complicated. Therefore, not only the above-mentioned needs but also the needs for facilitating the maintainability of the on-vehicle equipment are increasing more and more.

  In general, the on-board equipment described above undergoes inspection before leaving the vehicle base, so-called departure inspection. If an abnormality is found in the on-board equipment during this departure inspection, the train is operated smoothly by taking measures such as repairing the equipment and substituting for other vehicles or trains. However, in the case of inspection by visual inspection or manual operation, a great amount of time and man-hours are required, so introduction of means capable of performing the departure inspection more efficiently has been demanded.

  As a means for solving such a problem, a conventional inspection system represented by Patent Document 1 below performs a predetermined inspection on a device such as a door device or a broadcasting device by a management device that manages on-vehicle devices. A command is sent, information indicating the presence or absence of abnormality from each device is collected, and the inspection result is displayed on a predetermined display.

JP-A-01-138903

  However, the conventional technique represented by the above-mentioned Patent Document 1 is insufficient for the need to obtain the inspection result in a shorter time because the inspection of each device is executed serially. In particular, in recent years, the function of the device tends to become more sophisticated and complicated, and the conventional technique has a problem that it takes a long time to obtain all inspection results.

  The present invention has been made in view of the above, and an object of the present invention is to obtain an on-vehicle test apparatus and an on-vehicle test method capable of reducing the time required for inspection.

In order to solve the above-described problems and achieve the object, the present invention is an on-board test apparatus that performs inspection and testing of a plurality of devices mounted on a train, and the inspection work of one device is the other based whether affecting inspection of equipment, the equipment affecting other inspection from each device is set to a first inspection device for implementing in the foreground, the first inspection Among the devices other than the device , the device having the longest time required for inspection is set as the second inspection device that is implemented only in the background , and the device other than the first inspection device and the device other than the second inspection device An inspection device classification setting unit for setting the device as a third inspection device that can be implemented in both the foreground and the background, the first inspection device, the second inspection device, and the third inspection device. Inspection time and background A scheduling unit that schedules each inspection order of inspection equipment to be performed in the foreground and inspection equipment to be performed in the background based on availability and availability in the foreground, and an inspection order scheduled by the scheduling unit And an inspection execution unit that generates an inspection execution command for the first inspection device, the second inspection device, and the third inspection device.

  According to the present invention, the inspection equipment that can be executed in the background is scheduled, and the foreground inspection process and the background inspection process are performed in parallel, so the time required for the inspection can be shortened. There is an effect.

  Embodiments of an on-vehicle test apparatus and an on-vehicle test method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an on-vehicle test apparatus 100 according to an embodiment of the present invention. FIG. 2 is a diagram illustrating an example of a management table used in the automatic departure inspection process.

  The on-board test apparatus 100 shown in FIG. 1 mainly includes a departure inspection device selection unit (hereinafter simply referred to as “selection unit”) 11, a departure inspection execution unit (hereinafter simply referred to as “inspection execution unit”). 13, an inspection equipment category setting unit (hereinafter simply referred to as “setting unit”) 14, a scheduling unit 16, a departure inspection result display unit (hereinafter simply referred to as “result display unit”) 15, and a storage unit 12. It is configured.

  The management table 30 shown in FIG. 2 shows, as an example, a device code 31, a reference inspection cycle 32, a longest inspection cycle 33, a previous inspection execution date 34, and a previous inspection result 35. The reference inspection cycle 32 indicates a standard inspection cycle set for each device. The longest inspection period 33 indicates an inspection period that cannot be extended any longer.

  Of the items shown in FIG. 2, the equipment code 31, the reference inspection cycle 32, and the longest inspection cycle 33 are edited and updated by the ground data management device 20. This editing / updating work is performed, for example, when a device is added or the inspection cycle is changed. The data of the management table 30 edited and updated by the ground data management device 20 is recorded on, for example, a portable IC card and the storage unit via a predetermined data reading means installed in the on-board test device 100 12 is written. Note that the data of the management table 30 may be transferred by wireless means mounted on the ground data management device 20 and the on-vehicle test device 100.

  The inspection date and the inspection result are written in the previous inspection execution date 34 and the previous inspection result 35 of the management table 30 every time inspection is performed in the on-vehicle test apparatus 100.

  The management table 30 shown in FIG. 2 is configured so that the reference inspection period 32 and the like are described for each device (device code), but is not limited to this. For example, since there are a plurality of test items in the ATS, the management table 30 may be configured to manage the reference inspection period 32 and the like for each test item. In other words, the management table 30 may be divided into test item units instead of device units. Thus, if the test items are subdivided, the inspection time can be further shortened.

  FIG. 3 is a diagram illustrating an example of a train information management apparatus to which the on-vehicle test apparatus 100 according to the embodiment of the present invention is applied. In FIG. 3, as the components of the train information management device, central devices 100a and 100b mounted on both leading vehicles, a display 40 connected to each central device, and a terminal device 200a mounted on each vehicle, 200b, 200n-1, 200n, and devices A and B connected to each terminal device are shown. In addition, the train information management device is installed in each of a plurality of vehicles constituting one train, and is connected to each other to process train operation information, train position information, installed equipment information, etc. The on-vehicle test apparatus of the form handles one of the functions of the train information management apparatus.

  Central apparatuses 100a and 100b correspond to on-vehicle test apparatus 100 shown in FIG. The devices A and B are, for example, a door, a pantograph (hereinafter simply referred to as “panter”), a broadcasting device, a brake device, a marker lamp, and an ATS mounted on the vehicle.

  Each terminal device 200a to 200n is connected to each other via an inter-vehicle transmission line, transmits an inspection command from each central device to each device A, B, and further sends an inspection result from each device A, B to each central device. It is configured to be able to transmit to the device.

  The display device 40 is equipped with a display capable of touch panel operation. For example, when an ATS inspection execution operation is performed, the display results from the central devices are collectively displayed.

  Hereinafter, the content of the automatic departure inspection process performed by the on-vehicle test apparatus 100 according to the present embodiment will be specifically described. FIG. 4 is a flowchart showing an example of automatic departure inspection processing, FIG. 5 is a flowchart for explaining departure inspection equipment selection processing, and FIG. 6 shows an example of a menu displayed on the display unit. FIG. 7 is a diagram for explaining the inspection order scheduling process, and FIG. 8 is a diagram showing the inspection equipment executed in the foreground and the background based on the equipment attributes shown in FIG. It is a flowchart which determines the inspection apparatus to perform.

  In FIG. 4, the selection part 11 performs the selection process of an automatic departure inspection apparatus (step S10). Details of the selection process will be described later with reference to FIG.

  The devices selected by the selection unit 11 and the devices not selected are visualized and displayed on the display 40. This display is referred to as “menu display” (step S11). FIG. 6 shows an example of the menu display. For example, as an example of the selected equipment, ATS, equipment maintenance status, front / rear indicator lamp, broadcasting device, and brake are shown. Moreover, as an example of the equipment that was not selected, a panter lifting / lowering, door opening / closing, and a start-up test are shown.

  Next, when the crew member selects the inspection target device from the menu display, the setting unit 14 determines the inspection device to be executed in the foreground and the inspection device to be executed in the background from the selected devices. The scheduling unit 16 executes a comprehensive departure inspection order scheduling process (hereinafter simply referred to as “scheduling process”) in consideration of the time required for inspection of each device (step S12). Details of processing in the setting unit 14 and the scheduling unit 16 will be described later with reference to FIGS.

  Next, the inspection execution part 13 produces | generates the inspection instruction | command which makes each apparatus perform inspection according to the result of a scheduling process. And the result display part 15 displays the inspection result from each apparatus on the display 40 sequentially (step S13). Finally, the on-vehicle test apparatus 100 stores the inspection result in the storage unit 12 (step S14).

  As described above, since the on-vehicle test apparatus 100 according to the present embodiment discriminates devices that can be inspected in the background and schedules the inspection order of the devices, the foreground is conventionally used. Compared with the case where all the devices are inspected, the time required for the inspection can be greatly reduced.

(Department inspection equipment selection processing)
Next, the departure inspection device selection process in step 10 will be specifically described with reference to FIG. The selection unit 11 obtains the number of days elapsed from the previous inspection execution date (days after the previous inspection ΔD) by subtracting the previous inspection execution date from the day of the inspection (that day) (step S20).

  When the number of days after the previous inspection ΔD is longer than the longest inspection cycle 33 shown in FIG. 2 (Yes in step S21), the selection unit 11 selects the device to be inspected (step S22).

  In step 21, when the longest inspection cycle 33 is shorter than the number of days after the previous inspection ΔD (No in step S21), the selection unit 11 determines whether or not the previous inspection execution result is NG. When the previous inspection execution result is NG (step S23, Yes), the selection unit 11 selects the inspection target device in the same manner as described above (step S22).

  In step 23, when the previous inspection execution result is OK (step S23, No), the selection unit 11 does not select the inspection target device (step S24).

  Note that the screen of the display device 40 may be configured to display all the devices to be inspected and the devices not to be inspected so that the crew can arbitrarily select these devices. As shown in the display example of FIG. 6, the device to be inspected is displayed in black and the device that is not inspected is displayed in white so that the crew can determine whether the device is the device to be inspected. It is desirable to do.

  Next, the table shown in FIG. 7 shows device codes 51 and device attributes. The attributes of the device include operation necessity 52, background inspection availability 54, and inspection time 55.

  The necessity / unnecessity of operation 52 indicates whether or not an operation is required at the time of inspection, and whether or not inspection is possible in the background 54 indicates whether or not other inspections are affected even if executed in the background. . In the column of the device code 51 shown in FIG. 7, in order to make the description easy to understand, specific device names are illustrated instead of device codes generally indicated by numbers or symbols.

  The table shown in FIG. 7 is described as a specific example as follows. For example, in the case of a broadcasting apparatus, since it can be executed without the operation of the examiner, “unnecessary” is entered in the column of operation necessity 52. Next, even if other inspections are performed during the inspection of the broadcasting apparatus, there is no influence, and therefore “permitted” is entered in the column of the inspection availability 54 in the background. Furthermore, since the required time for inspection is relatively short, “short” is entered in the column of required time for inspection 55.

  In the case of a door, it can be executed without the operator's operation, but since it involves opening and closing the door, the field of whether or not the inspection can be performed in the background 54 should be considered in consideration of the influence on the worker being inspected. Is input “prohibited”.

  In the case of ATS, as with the door, it can be executed without any operation by the examiner, but it may take several minutes for the inspection. Entered.

  In the case of a punter, since an operation for raising and lowering the punter is required when measuring the operation time of the punter, “necessary” is entered in the column of necessity / non-necessity of operation 52, and the worker is instructed to In order to measure the operation time, “prohibited” is entered in the field of the check availability 54 in the background.

  The contents specified in the table shown in FIG. 7 are examples, and the present invention is not limited to these contents. In addition, in the column of the inspection required time 55 in FIG. 7, “long” or “short” is described as an example, but time notation may be used, and in this way, scheduling can be performed more finely. is there.

(Inspection equipment category setting section)
In FIG. 8, the setting unit 14 can check in the background based on whether or not the inspection target device selected from the menu display is a device that is highly likely to affect other inspections. Discriminate between devices and devices that cannot be checked in the background. Whether or not the device has a high possibility of affecting other inspections is based on the “necessity of operation” 52 shown in FIG.

  This will be specifically described as follows. Examples of inspection equipment to be executed in the foreground include equipment such as a door that can be affected by opening and closing of the door. In addition, examples of inspection equipment to be executed in the background include equipment that does not affect workers, such as ATS. The inspection equipment to be executed in the background includes equipment that can also be executed in the foreground.

  If it is determined that the selected device is a device that can be inspected in the background (step S30, Yes), the setting unit 14 determines whether the device requires the longest inspection time. For example, when both the ATS and the broadcasting apparatus are devices that can be inspected in the background, the setting unit 14 compares the inspection required time of the ATS and the inspection required time of the broadcasting apparatus. Here, although the time required for inspection is compared with respect to the two apparatuses, the number is not limited to two.

  If the setting unit 14 determines that the time required for the ATS inspection is the longest (Yes in Step S31), the setting unit 14 sets the ATS in the inspection device to be executed only in the background (Step S32). If the setting unit 14 determines that the required time for inspection of the broadcasting device is shorter than the required time for inspection of the ATS (No in step S31), the setting unit 14 sets the inspection device that can be implemented in both the foreground and the background to the broadcasting device. Is set (step S33).

  If it is determined in step S30 that the device cannot be inspected in the background (step S30, No), the setting unit 14 determines whether or not the operation requires an operation for inspection. For example, when the panter and the door device are items that cannot be inspected in the background, the setting unit 14 discriminates between devices that require an operator's operation and devices that do not require operation during the inspection. Here, although the time required for inspection is compared with respect to the two apparatuses, the number is not limited to two.

  In the case of a device that requires an operator's operation (step S34, Yes), for example, a panter is set as an inspection device to be preferentially performed in the setting unit 14 and foreground (step S35). Further, in the case of equipment that does not require the operator's operation (step S34, No), the setting unit 14 sets, for example, a door device as a normal inspection equipment to be implemented in the foreground (step S36).

  In this way, the setting unit 14 sets the inspection device to be preferentially executed. For example, when the inspection result of the device that requires the operator's operation is NG, the normal inspection device is being inspected. Since the cause of NG can be confirmed, the efficiency of inspection work can be improved.

  As described above, the setting unit 14 uses the first inspection device (for example, a door device) to be performed in the foreground based on whether or not the inspection operation of one device affects the inspection operation of another device. Or panta). Further, the setting unit 14 sets a device other than the first inspection device as a second inspection device (for example, ATS) that implements the device having the longest inspection time only in the background based on the inspection time. Then, a device other than the second inspection device is set as a third inspection device (for example, a broadcasting device) that can be implemented in both the foreground and the background.

(Scheduling part)
Next, the scheduling unit 16 is based on the inspection time of the first inspection device, the second inspection device, and the third inspection device, whether or not the background inspection can be performed, and whether or not the foreground operation is possible. Then, the scheduling process of each inspection order of the inspection device performed in the foreground and the inspection device performed in the background is performed (step S37).

  A specific example will be described as follows. For example, the scheduling unit 16 causes the second inspection device (for example, ATS) set in step S32 and the third inspection device (for example, broadcasting device) set in step S33 to be inspected in the background. Schedule as follows.

  In addition, when these inspection devices are serially inspected in the background (for example, after inspecting the ATS, inspecting the broadcasting device), the burden on the on-board testing device 100 can be reduced. Is possible.

  On the other hand, when these inspection devices are inspected in parallel in the background (for example, ATS inspection and broadcasting device inspection are performed in parallel), they are inspected compared to serial inspection. It is possible to shorten the time.

  For example, the scheduling unit 16 schedules the inspection device (for example, a door) set in step S35 and the inspection device (for example, a panta) set in step S36 to be inspected in the foreground.

  In addition, the scheduling unit 16 takes into account the time from the start of inspection in the foreground to the completion (foreground inspection time) and the time from the start of inspection in the background to the completion (background inspection time). Determine whether to check in the foreground or in the background, and set the above-mentioned third inspection device (for example, broadcasting device) as a device to be checked in the foreground or check in the background Decide whether to set the device.

  This will be described in more detail as follows. For example, the scheduling unit 16 causes the third inspection device (for example, a broadcasting device) set in step S33 to be inspected in the foreground, and only the second inspection device (for example, ATS) set in step S32. Can be scheduled to be checked in the background. In this scheduling, for example, the scheduling unit 16 determines whether or not the ATS inspection time is shorter than the total time of the broadcasting device inspection time, the door inspection time, and the panter inspection time. When the ATS inspection time is longer, the scheduling unit 16 performs scheduling so that only the ATS inspection is executed in the background.

  With this configuration, for example, it is possible to check a plurality of devices in the foreground while checking the ATS in the background. Further, the burden on the on-board test apparatus 100 can be reduced as compared with a case where inspection devices (for example, ATS and broadcasting apparatus) are inspected in parallel in the background.

(Department inspection execution department)
The inspection execution unit 13 generates an inspection execution command for the first inspection device, the second inspection device, and the third inspection device based on the inspection order scheduled by the scheduling unit 16. The result display unit 15 visualizes the inspection result from each device and displays it on the display 40.

  The types of inspection execution commands will be specifically described as follows. For example, in the case of ATS, the inspection execution unit 13 transmits an inspection execution command to a plurality of processing systems of the ATS. The result display unit 15 visualizes the inspection result from the ATS and displays it on the display 40.

  Similarly, in the case of a marker lamp, a lighting command (inspection execution command) is transmitted from the ATS to the marker lamp, and an inspection result is displayed depending on whether there is a response. In the case of a broadcasting device, the ATS performs a noise test (inspection execution command) on each broadcasting device, and the inspection result is displayed according to the sound volume. In the case of a punter, for example, by a worker's operation, the time from when a command to lower the panta is output to when it is actually lowered is measured, and the inspection result is displayed according to that time. The same applies to raising the punter. In the case of a startup test, the ATS sends a startup command (inspection execution command) to the automatic train control device (inverter, etc.), the control train is confirmed by the automatic train control device, and the check result is displayed as the inspection result. To do. In the case of a door, an opening / closing command (inspection execution command) is transmitted from the ATS to each door, and when an abnormality is confirmed during opening / closing, the position of the door confirmed to be abnormal is visualized and displayed.

  As described above, the on-vehicle test apparatus 100 according to the present embodiment schedules inspection devices that can be executed in the background, and performs the background inspection process in parallel with the foreground inspection process. Therefore, it is possible to perform a plurality of departure inspections simultaneously. For example, if the ATS inspection time is about several minutes and the other inspection devices are completed in about several tens of seconds, the conventional technology performs the inspection of each device serially. In some cases, the results of other inspection equipment could not be obtained until completion. In particular, as the function of the device is improved, such a problem appears more prominently. Therefore, there is a problem that the efficiency of the departure inspection work cannot be improved. The on-vehicle test apparatus 100 according to the present embodiment, for example, inspects a panter or door device that is a relatively short inspection device in the foreground, and in parallel, an ATS that is a relatively long inspection operation. Can be inspected in the background, so the time required for departure inspection can be greatly reduced compared to the prior art.

  In addition, the on-vehicle test apparatus 100 according to the present embodiment discriminates not only the length of the inspection work but also the equipment that is preferably inspected in the foreground, so that the inspection work of the worker is not hindered. It is possible to carry out departure inspection in line with the actual situation.

  In addition, since the on-board test apparatus 100 according to the present embodiment can perform the departure inspection by subdividing into test items as described above, the inspection time can be further shortened.

  In the above description, the on-board test device 100 is applied on the premise that inspection before departure is premised, but it can also be applied to inspections performed after warehousing, inspections performed periodically, and the like. is there.

  The structure shown in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and a part thereof is not deviated from the gist of the present invention. Needless to say, it is possible to change the configuration such as omission.

  As described above, the present invention can be applied to an on-vehicle test apparatus and an on-vehicle test method for automatically inspecting equipment mounted on a train, and in particular, to shorten the inspection time during departure inspection. It is useful as an invention that can.
