Description

  The present invention relates to a rail vehicle inspection system for inspecting a rail vehicle.

  Since rail vehicles such as the Shinkansen are required to ensure safe operation, various inspections are performed on the rail vehicles. Various inspections are roughly divided into regular inspections and temporary inspections.

  Periodic inspection includes general inspection, bogie inspection, work inspection and police inspection.

  In the general inspection, all devices of the rail vehicle are removed, and a detailed inspection is performed over the whole.

  In the cart inspection, main devices such as a brake device, a main motor, and a drive device mounted on the carriage of the rail vehicle are removed, and an inspection related to the cart including these main devices is performed.

  In the work inspection and the alternating inspection, inspection relating to a device that is particularly important in operation of a current collector, a carriage (including a brake device) and the like is performed without disassembling the rail vehicle. The alternating inspection is an inspection that is more detailed than the work inspection, and is performed with a longer inspection cycle than the work inspection.

  The temporary inspection is an inspection performed at a timing different from the periodic inspection, for example, when a sudden trouble occurs in the vehicle. For this reason, the inspection place where the inspection of the temporary inspection is performed is often set temporarily at or near the trouble occurrence point.

  Conventionally, the inspection results of these periodic inspections and temporary inspections are generally managed on a paper medium. However, there is a problem that it takes time and labor to share the inspection result among a plurality of inspectors. There is also a problem that human errors such as mistakes in entering test results are likely to occur.

  Thus, for example, Patent Document 1 proposes to digitize inspection results using an information terminal. In the system disclosed in this document, after the inspection is completed, the information terminal used by the inspector is connected to a personal computer or server so that the inspection result data stored in the information terminal is shared among the inspectors. It has become.

JP 2008-185556 A

  By the way, a regular inspection and a temporary inspection of a rail vehicle are generally performed simultaneously by a plurality of inspectors.

  However, in the system disclosed in Patent Document 1, since the inspection result data of each information terminal is shared with other inspectors for the first time after the inspection of the rail vehicle, the progress status and inspection results of other inspectors during the inspection. I can not grasp at all. Therefore, it is difficult to efficiently inspect the rail vehicle with a plurality of inspectors.

  An object of the present invention is to efficiently perform inspection of a rail vehicle by a plurality of inspectors.

  The present invention created in order to solve the above problems is a rail vehicle inspection system for inspecting a rail vehicle by a plurality of inspectors, and includes a plurality of information terminals carried by each inspector. The information terminal includes a first storage unit that stores first inspection result data relating to the rail vehicle of the inspector carrying the information terminal, and a second memory that stores second inspection result data relating to the rail vehicle of the other inspector. And a display unit capable of displaying the first inspection result data and the second inspection result data stored in the first storage unit and the second storage unit, and each information terminal is connected to other information terminals. The first inspection result data stored in the first storage unit of the other information terminal is received by direct wireless communication with the first storage unit, and the received first inspection result data is stored in the second storage unit as the second inspection result data. It is characterized by doing. Here, the “rail vehicle” includes a rail vehicle (for example, a bullet train) and a monorail vehicle. According to such a configuration, the mutual test result data can be displayed on the display unit of each information terminal by direct wireless communication between each information terminal. Therefore, even when a rail vehicle is inspected by a plurality of inspectors, the progress and inspection results of each inspector can be shared with each other in real time.

  Here, it is conceivable to communicate between each information terminal via a LAN (Local Area Network). However, since rail vehicles are very long, inspection of rail vehicles is often performed outdoors where no LAN is provided. In addition, in the case of a temporary inspection or the like, since the inspection place tends to be different every time, it is practically difficult to previously install a LAN for communication between information terminals at the inspection place. Accordingly, in the present invention, direct wireless communication that does not require a LAN is used for communication between each information terminal in consideration of the circumstances peculiar to such rail vehicles.

  The above configuration further includes a plurality of torque wrenches carried by each inspector, and each torque wrench tightens the fastening member of the rail vehicle with a set torque value and transmits tightening work data relating to the tightening work. Each information terminal generates the first inspection result data based on the tightening work data received from the torque wrench corresponding to the inspector carrying the information terminal, and the generated first inspection result data It is preferable to store in one storage unit. Here, the “fastening member” includes a bolt and a nut. If it does in this way, about the fastening operation | work of the fastening member by the torque wrench which occupies most inspections of a rail vehicle, the progress condition and inspection result can be shared in real time among several inspectors.

  In the above configuration, each information terminal further includes a third storage unit in which set torque value data of each fastening member of the rail vehicle is registered in advance, and each information terminal is an inspector carrying the information terminal. Set torque value data corresponding to the inspection content is read from the third storage unit and transmitted, and each torque wrench is set based on the set torque value data received from the information terminal corresponding to the inspector carrying the torque wrench. It is preferable to automatically set the torque value. In this way, since the set torque value corresponding to the inspection contents of the inspector is automatically set, it is possible to prevent the setting torque value from being set erroneously.

  In the above configuration, the display unit can input data using a touch panel, and the first inspection result data and the second inspection result data include signature data handwritten by the inspector who has performed each inspection using the touch panel. Is preferred. In this way, the inspector who performed each inspection can be specified from the signature data.

  According to the present invention, inspection of a rail vehicle can be efficiently performed by a plurality of inspectors.

  Hereinafter, an example of an embodiment according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the inspection system according to this embodiment is a system for inspecting a rail vehicle 2 by a plurality of inspectors 1 and includes a torque wrench 3 and an information terminal 4.

  For example, the plurality of inspectors 1 are divided into a first position (for example, the right side) and a second position (for example, the left side) of the rail vehicle 2 and perform the inspection. Also, in each of the first and second positions of the rail vehicle 2, for example, when the inspection vehicle 1 is divided into an inspector 1 that advances the inspection from the front to the rear and an inspector 1 that advances the inspection from the rear to the front. There is.

  Each of the plurality of inspectors 1 carries a dedicated torque wrench 3 and an information terminal 4. For this reason, there are a plurality of torque wrenches 3 and a plurality of information terminals 4 according to the number of inspectors 1. The torque wrench 3 and the information terminal 4 carried by the same inspector 1 function as a set of devices that can communicate with each other. In the present embodiment, direct wireless communication is possible between the set of torque wrench 3 and the information terminal 4. As the wireless communication, short-range communication such as Bluetooth (registered trademark) can be used. In addition, you may communicate by wire between a set of torque wrench 3 and the information terminal 4. FIG.

  As shown in FIG. 2, the torque wrench 3 tightens a bolt for fixing each inspection target of the rail vehicle with a set torque value, and includes a torque detection unit 31 that detects torque value data acting on the bolt. ing. The tightening work data including the torque value data detected by the torque detector 31 is wirelessly transmitted to the information terminal 4 that is paired with the torque wrench 3. In addition, although the volt | bolt is illustrated as a fastening member, a fastening member is not limited to this.

  The torque wrench 3 further has a function of preventing twice tightening (when a bolt already tightened with a specified torque value is tightened again) and a function of counting the number of tightening operations. The tightening work data transmitted wirelessly to the information terminal 4 further includes data related to twice tightening and data related to the number of times of tightening work. The torque value and the angle (the rotation angle of the bolt) are monitored at the same time to prevent double tightening. By counting the number of tightening operations, it is possible to determine that the bolt has been forgotten to be tightened when the number of tightening operations is smaller than the number of bolts required for tightening. At this time, since it has a function of preventing double tightening, it is possible to prevent the number of tightening operations from being erroneously counted by double tightening.

  The torque wrench 3 is automatically set with a set torque value corresponding to the inspection content of the inspector 1 carrying the torque wrench 3. The torque wrench 3 can also manually set the set torque value for the purpose of correcting the automatically set torque value.

  The information terminal 4 is a tablet terminal that includes a storage unit 41, a display unit 42, and a determination unit 43.

  The memory | storage part 41 memorize | stores the 1st test result data regarding the rail vehicle 2 of the inspector 1 who carries the information terminal 4, and the 2nd test result data regarding the rail vehicle 2 of the other inspector 1 And a third storage unit 41c in which all inspection content data of general inspection, cart inspection, work inspection, police inspection, and temporary inspection are registered in advance. The inspection content data includes set torque value data of each bolt of the rail vehicle 2. The storage unit 41 includes a storage device such as an SSD built in the information terminal 4.

  The display unit 42 can perform touch panel input. When the inspector 1 selects an inspection content such as a general inspection from the menu displayed on the display unit 42, set torque value data corresponding to the selected inspection content is read from the third storage unit 41c, and the information It is wirelessly transmitted to the torque wrench 3 that forms a pair with the terminal 4. When the torque wrench 3 receives the set torque value data from the information terminal 4 paired with the torque wrench 3, the torque wrench 3 automatically sets the set torque value based on the set torque value data.

  The determination unit 43 generates first inspection result data based on the tightening work data received from the torque wrench 3 paired with the information terminal 4. Specifically, the determination unit 43 compares the tightening work data received from the torque wrench 3 paired with the information terminal 4 and the inspection content data stored in the third storage unit 41c, up to the set torque value. Determine whether the bolt is tightened correctly. The first inspection result data includes the pass / fail of the tightening operation determined by the determination unit 43 and the actual tightening torque value, and these data are stored in the first storage unit 41a. The determination unit 43 is configured by a CPU built in the information terminal 4.

  The determination unit 43 detects the second tightening of the bolt based on the data regarding the second tightening, and detects forgetting to tighten the bolt based on the data regarding the number of tightening operations. The information terminal 4 has a function of generating an alarm when the determination unit 43 detects that the bolt has been tightened twice or forgotten. Thereby, so-called Pokayoke becomes possible. As an alarm notification method, any one of visual notification method displayed on the display unit 42 of the information terminal 4, audio notification method through sound, notification method through vibration tactile sense, or visual, auditory, and tactile information 2 A notification method by using two or more in combination can be used. Note that the torque wrench 3 may issue an alarm.

  Each information terminal 4 can directly wirelessly communicate with another information terminal 4. Through this wireless communication, each information terminal 4 transmits the first inspection result data stored in the first storage unit 41a of the information terminal 4 to the other information terminals 4. At the same time, each information terminal 4 receives the first inspection result data stored in the first storage unit 41a of the other information terminal 4, and also receives the first inspection result data of the other information terminal 4 received. The second inspection result data is stored in the second storage unit 41b. As wireless communication, short-range communication such as Bluetooth (registered trademark) can be used. The communicable distance between each information terminal 4 is set to be longer than the communicable distance between the pair of torque wrench 3 and the information terminal 4.

  By such wireless communication between each information terminal 4, each information terminal 4 can display each other's inspection result data on the display unit 42. Thereby, the plurality of inspectors 1 can share each progress status and inspection result with each other in real time. Specifically, for example, between the inspector 1 who carries out the inspection on the first side of the rail vehicle 2 and the inspector 1 that carries out the inspection on the second side of the rail vehicle 2, the progress status and the inspection result are displayed. Can be shared in real time. As a result, when there is a delay in the inspection of a part of the rail vehicle 2, all the inspections regarding the rail vehicle 2 can be rapidly advanced by increasing the number of inspectors 1 of the inspection in which the delay occurs. it can. In addition, even if the inspection of the rail vehicle 2 is resumed after being temporarily interrupted by a break or the like, each inspector 1 can accurately grasp the inspected location, so that the inspected location is duplicated. Can be avoided. Therefore, the inspection of the rail vehicle 2 performed by the plurality of inspectors 1 can be efficiently performed.

  In the present embodiment, the display section 42 of the information terminal 4 displays a sign entry field for handwriting input of the signature of the inspector 1 before the examination by the inspector 1 is started and / or after the examination is completed. (See FIG. 9 described later). For this reason, when the inspector 1 inputs a signature by hand on the touch panel in the signature entry field, signature data is generated. This sign data is included in the first inspection result data and the second inspection result data, and is shared among the plurality of inspectors 1.

  The information terminal 4 may further have a function of issuing an alarm when the signature entered in the signature entry field is different from the past signature of the inspector 1. Thereby, the impersonation of others can be prevented. The signature data preferably includes data obtained by converting the handwritten data into a character code by character recognition in addition to the handwritten data. Thereby, it becomes easy to search and analyze the inspection result for each inspector 1.

  Next, a processing flow of the inspection system according to the present embodiment will be briefly described. The inspection system according to the present embodiment can be applied to all inspections such as general inspection, bogie inspection, work inspection, police inspection, and extraordinary inspection. The case where it is applied will be described as an example. These replacement operations include a tightening operation for tightening the slot plate and / or the horn with a bolt, and a confirmation operation after the tightening operation. The post-confirmation work is performed by the inspector 1 who performed the tightening work.

  As shown in FIG. 3, the flow of the inspection system according to the present embodiment includes steps S1 to S9.

  In step S <b> 1, the inspector 1 uses the display unit 42 of the information terminal 4 to select an inspection type from general inspection, cart inspection, work inspection, alternating inspection, and extraordinary inspection. An example of a display screen for selecting the examination type is shown in FIG. In the case of the display screen of FIG. 4, for example, when “work inspection” is pressed among the inspection types, the process proceeds to step S2 corresponding to the work inspection. Even when a button for another examination type is pressed, the process proceeds to a step corresponding to the selected examination type.

  In step S <b> 2, the inspector 1 uses the display unit 42 of the information terminal 4 to input the inspection date, organization, car number, and the like. An example of the display screen of the information terminal 4 for inputting the organization and the car number is shown in FIG. In the case of the display screen of FIG. 5, if “confirm” at the bottom of the screen is pressed after inputting the organization and car number, the process proceeds to step S3.

  In step S <b> 3, the inspector 1 uses the display unit 42 of the information terminal 4 to select a replacement pattern for the slot plate and the horn. An example of the display screen of the information terminal 4 for selecting an exchange pattern is shown in FIG. As an exchange pattern, there is a case where there is a replacement of a chipboard and a case where a horn is exchanged. Of these, when the horn is replaced, only the first horn of the rail vehicle 2 is replaced, only the second horn is replaced, and the first and second horns may be replaced. included. In the case of the display screen of FIG. 6, after selecting one of the replacement patterns and pressing “OK” at the bottom of the screen, the process proceeds to step S4.

  In step S <b> 4, the inspector 1 uses the display unit 42 of the information terminal 4 to confirm the type of the board. This is because there are a plurality of types of the ground plates having different characteristics such as wear resistance. An example of the display screen of the information terminal 4 for confirming the type of the board is shown in FIG. In the case of the display screen of FIG. 7, after selecting one of the types of the slot boards and pressing “OK” at the bottom of the screen, the process proceeds to step S <b> 5. In addition, when the pattern which does not replace | exchange a board is selected by step S4, step S4 is abbreviate | omitted.

  In step S5, the inspector 1 performs a bolt tightening operation and a confirmation operation after the tightening operation, and confirms the inspection results of these operations in real time using the display unit 42 of the information terminal 4. An example of the display screen of the information terminal 4 displaying the inspection result is shown in FIG. In the display screen of FIG. 8, (1), (2), (a) and (b) are information about the filing plate, and (3), (4), (c) and (d) are information about the horn. Moreover, the upper part of the screen is a first area 5 showing a chipboard and a horn by a photograph or a schematic view, and the lower part of the screen is a second area 6 showing an inspection result by characters or symbols. In the first region 5, the portions corresponding to the respective bolts are color-coded according to the inspection result and the work progress. For example, the inspection pass portion 7 is a green circle, the inspection failure portion 8 is a red circle, and the inspection unnecessary portion 9 is a black circle. On the other hand, in the second area 6, the actual tightening torque value of each bolt and the determination result of the post-check (pass: OK, fail: NG) are displayed. Also in the second region 6, the portions corresponding to the respective bolts are color-coded according to the inspection result and the work progress. For example, the inspection pass part 10 is green, and the inspection failure part 11 is red. In the case of the display screen of FIG. 8, when “confirm” on the right side of the screen is pressed after all displayed examinations are completed, the process proceeds to step S <b> 6.

  Here, on the display screen of FIG. 8, the inspection results of the two inspectors 1 on the first and second sides are displayed together. This is realized by sharing the inspection result of each inspector 1 in real time by direct wireless communication between the respective information terminals 4. The display format of the inspection result can be freely changed. For example, it is possible to switch to a display screen on which only the inspection result of the inspector 1 carrying the information terminal 4 is displayed or a display screen on which only the inspection result of the other inspector 1 is displayed.

  In the display screen of FIG. 8, a passing range (designated torque) of the tightening torque value is displayed, and the inspector 1 recognizes in advance the tightening torque value to be applied to each bolt.

  In the display screen of FIG. 8, the judgment result of some bolts is rejected (NG), but if the part corresponding to the failed bolt is selected on the screen, the tightening operation can be performed again. Can be done. This tightening operation can be corrected in units of one bolt.

  In step S <b> 6, the inspector 1 uses the display unit 42 of the information terminal 4 to input the signature by hand in the user signature entry field of the torque wrench 3 carried by the inspector 1. An example of the display screen of the information terminal 4 displaying the user signature entry field is shown in FIG. In the case of the display screen of FIG. 9, after inputting a signature in the user signature entry field and pressing “OK” at the bottom of the screen, the process proceeds to step S <b> 7. In this embodiment, the sign of the user of the torque wrench 3 is obtained after completion of the tightening work and the post-confirmation, but the user of the torque wrench 3 is requested before starting the tightening work and post-confirmation. You may make it ask for a signature.

  In step S <b> 7, the inspector 1 uses the display unit 42 of the information terminal 4 to confirm a check table for the replacement work of the slot plate and the horn. An example of the display screen of the information terminal 4 displaying the check table is shown in FIG. In the case of the display screen of FIG. 10, if there is no problem with each item displayed in the check table, the inspector 1 sequentially checks the check boxes corresponding to the items in the check table. After checking all the check boxes, pressing “OK” at the bottom of the screen shifts to step S8.

  In step S8, the inspector 1 uses the display unit 42 of the information terminal 4 to finally confirm the list of inspection results so far. An example of the display screen of the information terminal 4 that displays the inspection result list is shown in FIG.

  In step S <b> 9, the inspector 1 uses the display unit 42 of the information terminal 4 to input the signature by handwriting in the person-in-charge signature entry field. In the case of the display screen of FIG. 11, all the check boxes provided for predetermined items in the inspection result list are checked, and after the signature is handwritten in the person-in-charge sign entry field at the top of the screen, “ When “OK” is pressed, a series of data so far is stored as a final result. After saving, the display unit 42 of the information terminal 4 returns to the initial screen shown in FIG.
