Description

  The present invention relates to a train radio system in which a mobile station mounted on a train can communicate with a central device via a base station.

  In a conventional train radio system, a mobile station is mounted on a train, and an audio signal, a control signal, and a data signal are transmitted between the inside of the train and the outside of a command station that serves as a train management unit including a base station, a central device, and an operation management device. Such data communication is performed. An example of a train radio system that performs data communication is a mobile radio system disclosed in Patent Document 1.

  In a conventional train radio system, for example, a mobile station mounted on a train has vehicle state information (such as failure information) from an on-board monitor device, a stop signal from a stop button, an on-vehicle ATO (Automatic Train Operation) device. A signal input and data input from an on-board device such as a train control signal is taken in, and transmission data including this content is transmitted.

  On the other hand, in the train management unit, the transmission data of the mobile station is received as received data by the central device via the base station (device), and the central device receives the received data as data related to the train operation. It is transmitted to external equipment such as ATO central equipment, CTC equipment, and power distance control equipment.

  Further, in the above-described conventional train radio system, for example, a mobile station performs a communication state test (communication test) with a central device via a base station for a start-up inspection or a maintenance inspection at the start of train operation. It has been broken. As a communication test, for example, a call is performed between a train crew and a commander at a command station.

JP 2001-86055 A

  As described above, in the conventional train radio system, a communication test such as a call test is performed in a start-up inspection and a maintenance check at the start of operation, but in a mobile station that transmits an important signal related to train operation, There is no means for checking the state of signal input and data input from an on-board device (such as an on-board monitor device) to the mobile station. Therefore, if the input to this mobile station is interrupted for some reason, even if a failure occurs after the train is operating, the mobile station will not send a signal indicating the occurrence of the failure. There was a problem that the state could not be grasped and the train operation was greatly affected.

  In mobile stations, there is no testing means to confirm the status of signal input and data input from on-board equipment of trains, such as on-board monitoring equipment, stop button, on-board ATO equipment, etc., and confirmation tests are conducted at start-up inspections, maintenance inspections, etc. The reason why the implementation is difficult is as follows.

  First, when a mobile station receives a signal input or data input from an on-board monitor device or the like, it is transmitted to the central device via the base station (device) as it is. For this reason, even if signals and data are input to the mobile station from the on-board monitor device, stop button, on-vehicle ATO device, etc. as a test, the mobile station sends the data as it is to the central device via the base station. The central device transmits data to the ground external devices such as the operation management device, the ATO central device, the CTC device, and the power distance control device as they are.

  As a result, despite the fact that on-board equipment signal input and data input (these inputs only indicate temporary information) were performed on the mobile station as a test, the ground side (train management unit) As a result of determining the provisional information as true information at the side), it may cause a failure and misrecognition in the train, greatly affect train operation such as power stoppage and signal stop, and hinder stable operation There was a problem that there was a possibility. For example, if the emergency signal (emergency signal: a signal that stops the power on the orbit) is output as a test signal, but the ground side has misrecognized that the emergency signal was output as a normal signal, There was a problem that the electric power on the track was stopped, which greatly affected the operation of other trains.

  In a conventional train radio system, a test result is obtained even if a signal is input to a mobile station from a train on-board device (on-vehicle monitor device, stop button, on-vehicle ATO device, etc.) and data is input to the user. There is a problem that the quality of the input state to the mobile station cannot be judged.

  The present invention has been made to solve the above-mentioned problems, and train radio that can output to a user the result of the input state such as signal input and data input from the on-board device of the train to the mobile station. The purpose is to realize the system.

According to a first aspect of the present invention, there is provided a train radio system comprising: a train equipped with a predetermined on-board device that is used internally and outputs predetermined processing result information; and a mobile station capable of inputting the predetermined processing result information; A train installed independently from the train and having a central station capable of communicating with the mobile station and a central device capable of receiving transmission data including the predetermined processing result information from the mobile station via the base station A train radio system including a management unit, wherein the train is further equipped with an on-board indicator, and the mobile station is in a communication mode with the base station when the test mode is set, as the result of the determination the quality of the input state to move station information can be displayed quality determination information based on the determination result to the vehicle on the display.

Mobile station in a train radio system is the invention of claim 1, wherein, in the setting of the test mode, and determine the quality of the input state to move station of a predetermined processing result information, quality determination based on the determination result since information can be displayed on the onboard display, train users, such as crew by referring to the vehicle on the display unit in a test mode, simply the quality of the input state of the mobile station of predetermined processing result information Can be recognized.

Further, since the mobile station cuts off communication with the base station when the test mode is set, the mobile station can reliably prevent the transmission data including the predetermined processing result information from being transmitted to the train management unit during the test mode. Can be avoided.

<Prerequisite technology>
In order to facilitate understanding of the features of the present invention, a specific configuration and operation of a conventional train radio system which is a prerequisite technology of the present invention will be described.

  FIG. 7 is a block diagram showing a configuration of a conventional train radio system which is a prerequisite technology of the present invention. As shown in the figure, in the conventional train radio system, the train 51 is provided with various on-vehicle devices including a mobile station 52, an on-vehicle monitor device 55, a stop button 56, and an on-vehicle ATO device 57. On the other hand, the central device 54 arranged at the command station in the train 51 and the train management unit 5 can communicate with the mobile station 52 of the train 51 via the base station 53 (53a, 53b). Information including a voice signal, a control signal, and a data signal obtained from the monitor device 55, the stop button 56, and the on-vehicle ATO device 57 can be transmitted from the mobile station 52 to the base station 53 as transmission data.

  Hereinafter, a device that collectively refers to the on-vehicle monitor device 55, the stop button 56, and the on-vehicle ATO device 57 is referred to as an “on-vehicle device 55X”, and an audio signal from the on-vehicle monitor device 55, the stop button 56, and the on-vehicle ATO device 57. The information including the control signal and the data signal may be collectively referred to as “processing result information S55X”.

  On the other hand, the train management unit 5 includes a central device 54, an external ground device 58, and a base station 53, and can communicate with the train 51 by wireless communication between the base station 53 and the mobile station 52. The base station 53 is composed of a plurality of base stations 53a, 53b,..., Each being distributed and arranged at a predetermined location.

  The central device 54 receives the transmission data S52 obtained from the mobile station 52 via the base station 53, and the contents of the transmission data S52 are used as transmission data relating to train operation as an operation management device, an ATO central device, and a CTC device. , To the ground external device 58 including a power distance control device.

  FIG. 8 is an explanatory diagram showing a sequence of control signals and data signals which are processing result information of the conventional train radio system shown in FIG. In the conventional train radio system shown in FIG. 7, control signals and data signals are transmitted in the flow shown in FIG.

  In FIG. 8, the base station 53 has a function of receiving radio waves from the mobile station 52 and transferring data to the central device 54, and converting data from the central device 54 into radio waves and transmitting the radio waves to the mobile station 52. Therefore, it is collectively shown as “central device / base station” in the central device 54.

  First, in step ST51, the mobile station 52 provided in the train 51 receives vehicle state information (such as fault information) from the on-board monitor device 55, a stop signal from the stop button 56, and a train control signal from the on-vehicle ATO device 57. Is received from the on-board device 55X.

  In step ST52, the mobile station 52 transmits transmission data S52 including the processing result information S55X to the central apparatus 54 via the base station 53.

  Thereafter, in step ST53, transmission data S54 including transmission data S52 (processing result information S55X) is transmitted from the central apparatus 54 to the ground external apparatus 58. The ground external device 58 controls the operation of the train including the train 51 based on the transmission data S54 that is data related to the train 51 operation.

  In the conventional train radio system shown in FIG. 7 and FIG. 8, for example, a communication state test with the central device 54 via the base station 53 (for the start-up inspection and the maintenance inspection at the start of operation of the train 51). Communication test). As a communication test, for example, a call is performed between a crew member of the train 51 and a commander at the command station.

  As described above, in the conventional train radio system, a communication test such as a call test is performed in a start-up inspection or a maintenance inspection at the start of operation. However, the mobile station 52 itself that receives the processing result information S55X that is an important signal related to the operation of the train 51 and transmits the transmission data S52 including the processing result information S55X has a means for confirming whether the input state of the processing result information S55X is acceptable. Absent. Therefore, as described above, if the input of the processing result information S55X to the mobile station 52 is interrupted due to some factor, even if a failure occurs after the train 51 is operated, the train management unit 5 uses the vehicle of the train 51. The state cannot be grasped and the operation of the train 51 may be greatly affected.

  The reason is that when the mobile station 52 inputs the processing result information S55X from the on-board device 55X, all the data is transmitted as it is to the central device 54 via the base station 53 as transmission data S52. For this reason, even if the processing result information S55X is input from the onboard device 55X of the train 51 to the mobile station 52 as a test, the mobile station 52 uses the content as it is as transmission data S52 via the base station 53 via the central device 54. The central device 54 transmits the content of the transmission data S52 to the ground external device 38 as transmission data S54 as it is.

  As a result, as described above, although the processing result information S55X of the on-board device 55X is output to the mobile station 52 as a test, a failure occurs in the train 51 in the train management unit 5 having the central device 54. As a cause of misrecognition, there is a problem that it has a great influence on train operation such as power stoppage and signal stop, and may interfere with stable operation.

<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of a train radio system according to Embodiment 1 of the present invention.

  As shown in the figure, the train radio system according to the first embodiment includes a train management unit 1 and a train 11.

  The train 11 is equipped with a mobile station 12, an on-vehicle monitor device 15, a stop button 16, an on-vehicle ATO device 17, a test condition generating device 19, and a (on-vehicle) display 20.

  The on-vehicle monitor device 15 outputs vehicle state information (such as failure information) S15 of the train 11 to the mobile station 12 by serial transmission, for example. When the button is pressed, the stop button 16 outputs a stop signal S16 to the mobile station 12, for example, by signal transmission using a contact. The on-board ATO device 17 outputs a train control signal S17 for automatic train operation to the mobile station 12 by signal transmission using, for example, a contact.

  Hereinafter, for convenience of explanation, when the on-board monitor device 15, the stop button 16, and the on-vehicle ATO device 17 are generically referred to, they may be simply referred to as “on-vehicle device 15X” (predetermined on-vehicle device). When the state information S15, the stop signal S16, and the train control signal S17 are collectively referred to, they may be simply referred to as “processing result information S15X”.

  The test condition generator 19 outputs to the mobile station 12 test condition information S19 for instructing test conditions such as test start and test cancellation using an operation by a test switch as a trigger.

  The mobile station 12 transmits transmission data S12 including the processing result information S15X toward the base station 13 (13a, 13b) during normal time (in operation mode). The normal time means a period other than the test mode described later.

  On the other hand, in the test mode until the test condition information S19 instructs the start of the test and the end of the test is instructed, the mobile station 12 performs an input state pass / fail judgment test on the processing result information S15X and indicates the judgment result. The test determination result information D12 is output on the display 20 so that the user can visually recognize it. At this time, the mobile station 12 masks the wireless transmission by blocking the wireless transmission of the transmission data S12 including the processing result information S15X. The indicator 20 has display functions such as LED lighting and display display. In addition, when the display device 20 is used even in the normal time, the user can be made to recognize that the display is a display in the test mode from a comparative viewpoint by changing the lighting cycle of the LED from the normal time in the test mode.

  On the other hand, the train management unit 1 installed independently of the train 11 includes a central device 14, an external ground device 18, and a base station 13, and communicates with the train 11 by wireless communication between the base station 13 and the mobile station 12. Is possible. The base station 13 is composed of a plurality of base stations 13a, 13b,..., Each being distributed and arranged at a predetermined location.

  The central apparatus 14 receives transmission data S12 transmitted from the mobile station 12 via the base station 13, and manages the contents of the transmission data S12 (processing result information S55X) as transmission data S14 that is data related to train operation. It is transmitted to the ground external device 18 including a device, an ATO central device, a CTC device, a power distance control device, and the like. And the ground external apparatus 18 performs operation control of the train including the train 11 based on the transmission data S14.

  FIG. 2 is an explanatory diagram schematically showing a test operation mainly in the test mode in the train radio system of the first embodiment.

  In FIG. 2, the base station 13 receives the radio wave from the mobile station 12 and passes the data to the central device 14, and also converts the data from the central device 14 into a radio wave and transmits it to the mobile station 12. Therefore, it is collectively shown as “central device / base station” including the central device 14.

  The train radio system according to the first embodiment indicates the input state of the processing result information S15X output from the onboard device 15X to the mobile station 12 in the start-up inspection and maintenance inspection when the train 11 starts operation. A test operation to perform a pass / fail judgment test is possible.

  Hereinafter, a test operation of the train radio system according to the first embodiment will be described with reference to FIG.

  First, a test ON operation is performed in step ST11. That is, in step ST11, the user (crew, etc.) moves the test condition information S19 instructing the test start from the test condition generator 19 by operating a test switch or the like provided in the test condition generator 19 of the train 11. By outputting to the station 12, the mobile station 12 is made to recognize the start of the test mode. In step ST11, information output means of test condition information S19 other than the test switch may be used.

  As a result, the mobile station 12 can recognize that the test mode is started (test mode ON), and executes the test operation in the test mode.

  Next, in step ST12 (information input process), the processing result information S15X output from the on-board device 15X is input to the mobile station 12. The mobile station 12 masks the wireless transmission for transmitting the transmission data S12 including the processing result information S15X to the base station 13 during the test mode. Therefore, the transmission data S12 including the processing result information S15X is not wirelessly transmitted to the train management unit 1 in the test mode.

  Then, in step ST13 (test processing), a quality determination test of the input state to the mobile station 22 with respect to the processing result information S15X is performed, and the test determination result information D12 indicating the determination result can be visually recognized by the user on the display 20 Output to. Note that the test determination result information D12 includes defect signal identification information indicating which of the onboard monitor device 15, the stop signal S16, and the train control signal S17 is defective.

  Note that the test determination by the mobile station 12 is performed based on whether or not the vehicle state information S15, the stop signal S16, and the train control signal S17 constituting the processing result information S15X are input.

  As a result, by visually recognizing the display content of the display device 20, the vehicle state information S15 output from the on-vehicle monitor device 15, the stop button 16, and the on-vehicle ATO device 17 included in the on-vehicle device 15X, It is possible to recognize the test determination result regarding the input state of the stop signal S16 and the train control signal S17 to the mobile station 12.

  Thereafter, a test mode OFF operation is performed in step ST14. That is, when the user operates a test switch or the like provided in the test condition generating device 19 of the train 11 and outputs test condition information S19 instructing cancellation of the test from the test condition generating device 19 to the mobile station 12, The mobile station 12 is made to recognize the end of the test mode. In step ST14, the signal output means of the test condition information S19 other than the test switch may be used.

  As a result, the mobile station 12 can recognize that the test mode has been canceled (test mode OFF), and thereafter returns to the operation mode in which the normal operation is performed.

  After step ST15, since the operation mode returns to the normal operation mode, the processing result information S15X is output from the onboard device 15X in step ST15, and the transmission data S12 including the processing result information S15X is output in step ST16 to the base station 13 and the central device. The transmission data S14 including the transmission data S12 (processing result information S15X) is output to the ground external apparatus 18 in step ST17. Then, the ground external device 18 recognizes the vehicle state grasp of the train 11 based on the transmission data S <b> 14, and performs operation control of various trains including the train 11.

  As described above, the mobile station 12 in the train radio system according to the first embodiment, from the onboard device 15X of the train 11 including the onboard monitor device 15, the stop button 16, and the onboard ATO device 17 when the test mode is set. It is possible to test the quality of the input state of the processing result information S15X to the mobile station 12, and to display the test determination result information D12 based on the test result on the display 20 so as to be visually recognizable to the user. it can.

  As a result, a user (such as a crew member) can easily recognize whether the processing result information S55X is input to the mobile station 12 by referring to the display device 20.

  Further, in this case, since the test determination result information D12 includes the above-described defective signal identification information, the user can use the line (for example, a mobile station) where a failure occurs based on the defect signal identification information in the test determination result information D12. 12-between the on-vehicle monitor device 15) can be specifically specified. In this case, the test determination result information D12 indicates that the input state of the vehicle state information S15 output from the on-board monitor device 15 is defective.

  Further, when the test mode is set, the mobile station 12 of the train 11 receives the processing result information S15X from the on-board device 15X, and the base station of the transmission data S12 including the processing result information S15X to the base station 13 Wireless transmission to 13 is suppressed (blocked). Therefore, the processing result information S15X input to the mobile station 12 as a test from the onboard device 15X of the train 11 is not transmitted to the base station 13 and the central device 14 as transmission data S12, and the ground external device 18 Therefore, the transmission data S14 including the processing result information S15X is not transmitted.

  For this reason, in the train management unit 1 existing on the ground side (command center, etc.), the processing result information S15X under test is recognized as actual information, and adverse effects such as causing a misrecognition such as a failure in the train 11 are caused. Confirmation test regarding whether the processing result information S15X from the onboard device 15X of the train 11 such as the onboard monitor device 15 to the mobile station 12 is acceptable without adversely affecting other train operations. Can be done.

  Thus, the processing result information output from the onboard device 15X to the mobile station 12 by switching the test mode / operation mode of the mobile station 12 by the test condition information S19 output from the test condition generating device 19 The processing content of S15X can be appropriately distinguished between the test mode and the operation mode. As a result, the train radio system according to the first embodiment can perform a confirmation test for determining whether the input of the processing result information S15X from the on-board device 15X to the mobile station 12 does not adversely affect the train operation. is there.

<Embodiment 2>

The stop button 26 outputs a stop signal S26 to the mobile station 22 when the button is pressed. The on-board ATO device 27 outputs a train control signal S27 for automatic train operation to the mobile station 22.

  Hereinafter, for convenience of explanation, when the on-board monitor device 25, the stop button 26, and the on-vehicle ATO device 27 are generically referred to, they may be simply referred to as “on-vehicle device 25X” (predetermined on-vehicle device). When the state information S25, the stop signal S26, and the train control signal S27 are collectively referred to, they may be simply referred to as “processing result information S25X”.

  Further, the test condition generating device 29 outputs test condition information S29 for instructing test conditions such as test start and test cancellation to the mobile station 22 by using an operation by a test switch as a trigger.

  The mobile station 22 transmits transmission data S22 including the processing result information S25X toward the base station 23 (23a, 23b) during normal times (in the operation mode).

And test data including the processing result information S25X is transmitted to the base station 13 as transmission data S22.

  The train management unit 2 installed independently of the train 21 includes a central device 24, an external ground device 28, a base station 23, and a (for management) display 30, and wireless communication between the base station 23 and the mobile station 22 is performed. Communication with the train 21 is possible. The base station 23 is composed of a plurality of base stations 23a, 23b,..., Each being distributed and arranged at a predetermined location.

  When the central apparatus 24 receives the transmission data S22 obtained from the mobile station 22 via the base station 23 and there is no identification signal instructing that the transmission data S22 is test data, the transmission data S22 is related to train operation. Data is transmitted as transmission data to the ground external device 28 including an operation management device, an ATO central device, a CTC device, a power distance control device, and the like. And the ground external apparatus 28 performs operation control of the train including the train 21 based on the transmission data S24.

  On the other hand, when the transmission data S22 includes an identification signal that indicates that it is test data, the central device 24 performs a pass / fail determination test on the processing result information S25X included in the transmission data S22, and the test determination result information D24 is obtained. The information is displayed (output) on the display 30 so that it can be visually recognized by a user (commander or the like) outside the train management unit 2. At this time, the central device 24 blocks transmission of the transmission data S24 including the processing result information S25X (transmission data S22) to the ground external device 28. The indicator 30 has display functions such as LED lighting and display display.

  FIG. 4 is an explanatory diagram schematically showing a test operation mainly in the test mode in the train radio system of the second embodiment.

  In FIG. 4, the base station 23 has a function of receiving radio waves from the mobile station 22 and transferring data to the central device 24, and converting data from the central device 24 into radio waves and transmitting it to the mobile station 22. Therefore, it is collectively shown as “central device / base station” in the central device 24.

  In the train radio system according to the second embodiment, the processing result information S25X output from the onboard device 25X to the mobile station 22 is checked on the train management unit 2 side at the start of work or maintenance check at the start of operation of the train 21. A test operation to perform a judgment test is possible.

  Hereinafter, the test operation of the train radio system according to the second embodiment will be described with reference to FIG.

  First, a test ON operation is performed in step ST21. That is, in step ST21, the user (crew, etc.) moves the test condition information S29 instructing the test start from the test condition generating device 29 by operating a test switch or the like provided in the test condition generating device 29 of the train 21. By outputting to the station 22, the mobile station 22 is made to recognize the start of the test mode. In step ST21, signal output means of test condition information S29 other than the test switch may be used.

  As a result, the mobile station 22 can recognize that the test mode is started (test mode ON), and executes the test data processing operation in the test mode.

  Next, in step ST22 (information input process), the processing result information S25X output from the on-board device 25X is input to the mobile station 22.

  Thereafter, in step ST23, the mobile station 22 performs a test data processing operation for obtaining test data including an identification signal instructing that it is in the test mode and the processing result information S25X, and uses the test data as transmission data S22. Wireless transmission is performed toward the station 23.

  The central device 24 that has received the transmission data S22 via the base station 23 recognizes that the transmission data S22 is test data based on the identification signal included in the transmission data S22. When the central device 24 recognizes that the transmission data S22 is test data, the central device 24 masks transmission of the transmission data S24 including the processing result information S25X to the ground external device 28. Therefore, the transmission data S24 including the processing result information S25X is not transmitted to the ground external device 28 in the test mode.

  In step ST24 (test processing), the central device 24 performs a pass / fail judgment test on the input state of the central device 24 with respect to the processing result information S25X, and provides test judgment result information D24 indicating the judgment result of the train management unit 2. The data is output on the display 30 so that the user can visually recognize it.

That is, the central device 24 checks whether or not the processing result information S25X included in the transmission data S22 is correctly input to the central device 24 via the mobile station 22 and the base station 23. Further, the test determination result information D24 includes failure signal identification information for identifying which of the on-board monitoring device 25, the stop signal S26, and the train control signal S27 is defective.

  As a result, the external user visually recognizes the display content of the display device 30, and thereby the vehicle state information output from the on-vehicle monitor device 25, the stop button 26, and the on-vehicle ATO device 27 included in the on-vehicle device 25X. It is possible to recognize the test determination result regarding the input state to the central apparatus 2 via the mobile station 22 and the base station 23 of the S25, the stop signal S26 and the train control signal S27.

  Thereafter, a test mode OFF operation is performed in step ST25. That is, when the user operates a test switch or the like provided in the test condition generating device 29 of the train 21 and outputs test condition information S29 instructing the test release from the test condition generating device 29 to the mobile station 22, The mobile station 22 is made to recognize the end of the test mode. In step ST25, signal output means of test condition information S29 other than the test switch may be used.

  As a result, the mobile station 22 can recognize that the test mode has been canceled (test mode OFF), and thereafter returns to the operation mode in which the normal operation is performed.

  After step ST26, since the operation mode returns to the normal operation mode, the processing result information S25X is output from the onboard device 25X in step ST26, and the transmission data S22 including the processing result information S25X is transmitted to the base station 23 and the central device in step ST27. The transmission data S24 including the transmission data S22 (on-vehicle device 25X) is output to the ground external device 28 in step ST28.

  And the ground external apparatus 28 recognizes the vehicle state grasp etc. of the train 21 based on transmission data S24, and performs operation control of the various trains including the train 21.

It is possible to test the quality of the input state when the result information S25X reaches the central device 24 via the mobile station 22 and the base station 23, and the user of the train management unit 2 uses the display 30 for the test determination result information D24. Can be output visually recognizable.

  Further, since the test determination result information D34 includes defective signal identification information, an external user, for example, based on the test determination result information D24 displayed on the display device 30, the line (for example, the mobile station 22) in which a failure has occurred. -Between the on-board monitoring device 25) can be specified specifically.

  In addition, when the test mode is set, the central device 24 of the train management unit 2 receives the processing result information S25X and the transmission data S22 including the identification signal instructing the test mode. Since transmission of the transmission data S24 including the information S25X is suppressed (blocked), the transmission data S24 including the processing result information S25X is not transmitted to the ground external device 28.

  For this reason, in the train management unit 2 existing on the ground side (command station, etc.), the processing result information S25X under test is recognized as actual information, and an adverse effect that causes misrecognition such as a failure in the train 21 is ensured. The transmission data from the onboard device 25X of the train 21 such as the onboard monitor device 25 to the central device 24 via the mobile station 22 and the base station 23 without adversely affecting other train operations. It is possible to perform a confirmation test regarding the input quality of the processing result information S25X included in S22. That is, it is possible to perform a data input confirmation test of the processing result information S25X on the same communication path as the operation state (path from the mobile station 22 to the central device 24).

  As described above, when the central device 24 in the train radio system according to the second embodiment recognizes that the transmission data S22 is test data based on the identification signal (mode identification information), the transmission data S24 is transmitted to the ground external device 28. Since the transmission is cut off, it is possible to reliably avoid an adverse effect caused by the processing result information S25X being transmitted to the ground external device 28 in the test mode.

  As described above, the train radio system according to the second embodiment switches the test mode / operation mode of the mobile station 22 according to the test condition information S29 output from the test condition generating device 29, so that the on-board device 25X. The processing contents of the processing result information S25X output from the mobile station 22 to the mobile station 22 can be appropriately distinguished between the test mode and the operation mode. As a result, the train radio system of the second embodiment confirms whether the input state of the processing result information S25X included in the transmission data S22 from the onboard device 25X to the central device 24 is acceptable without affecting the train operation. A test can be performed.
