This paper relates to a train information transmission system and a verification method for the information transmission system. ``Conventional technology'' Conventional transponder-based train information transmission equipment and verification methods for information transmission equipment generally have a single-system configuration for on-board equipment. "Problem to be Solved by the Invention" These conventional techniques achieve a certain degree of reliability as a device when considering the reliability of the device, but
With a single system, if a failure were to occur, it would be unavoidable that train operation would be disrupted, so there were expectations for a technology that would create a more reliable multiple system. The present invention was made in view of this conventional situation, and aims to construct a multi-system system with a reliable and simple configuration. "Means for Solving the Problems" The gist of the present invention for achieving the above object is as follows: (l) By wireless communication between a ground switch installed on the ground and an onboard switch installed on the train. In a transponder-type train information transmission device that transmits information, the train includes a transmitting modem for transmitting signals from onboard the train, a receiving modem for receiving instruction information from the ground, and a receiving and transmitting device. In addition to having multiple transmission units with a control unit that controls various functions of the train, a receiving antenna and a transmitting antenna for inspection are installed on the train, and control signal processing is performed to issue train control signals based on instruction information from the ground. In addition to providing a control unit with a status determination unit that determines whether the transmission unit becomes a transmission system that emits a test signal, and a test signal storage unit that stores the test signal, the control unit includes a a test notification unit that notifies the operator of the start of the test; and a test signal transmitter that extracts a test signal from the test signal storage unit and transmits the test signal from the transmission modem via the test transmitting antenna after the test notification unit has notified the test. The control unit further includes an inspection notification receiving unit that receives the inspection notification and notifies that the signal received by the receiving antenna is an inspection signal, and an inspection notification receiving unit that receives the inspection notification from the inspection transmitting antenna. The train is characterized in that the control section is provided with a reception verification section that includes a test verification section that verifies the coincidence between the test signal received by the reception modem via an antenna and the test signal stored in the test signal storage section. Information transmission device. 2 A plurality of types of test signals are stored in the test signal storage unit, and the plurality of types of test signals have l and 0 at each bit position.
Information transmission for trains described in paragraph 1, including those in which the and is reversed*a
．． 3 Information is transmitted by radio communication between the ground element installed on the ground and the onboard element installed on the train, with a transmitting modem for sending signals from onboard and a receiving modem for receiving information. In a method for verifying information transmission equipment for a train equipped with a plurality of transmission units having a receiving modem and a control unit for controlling various functions of the train including receiving and transmitting, directly transmitting the type of test signal, transmitting the test signal from the one transmission device to the onboard component within a predetermined time, and the receiving transmission unit receiving the test signal, and transmitting the test signal in its own memory. The method of verifying an information transmission device is characterized in that normal operation of each transmission unit and the entire transmission unit is confirmed by comparing the test signal with the predetermined time and the test signal. ``Operation'' A transponder-type train information transmission device controls train operation by transmitting information through wireless communication between a beacon installed on the ground and an onboard device installed on the train. be. All of the multiple transmission units installed on the train have common components, and the status determination section determines whether or not the own unit will be the transmission system for the inspection signal based on the installation position and preset order. is being judged. Transmission units other than the transmitting system are the receiving system. Once the role of each system is determined in this way, the control signal processing unit receives and processes instruction information from the onboard train via the receiving antenna and receiving modem, and each transmission unit on the train processes the control signal. emits. The multiple control signals emitted from each transmission unit become final control signals through majority vote or master-slave relationships, and train operation is controlled. Since operation instruction information is provided intermittently, equipment inspections are performed at times when operation control is not in progress. The inspection is performed as follows. Before emitting a test signal, the transmission unit that becomes the transmission system notifies the test start through a direct line from the test notification section.After this test notification, the test signal transmission section retrieves the test signal from the test signal storage section and sends it to the transmitting modem. The test signal is sent to the test transmitting antenna via the In each transmission unit, the test notification receiving unit that receives the test notification instructs that there is a test, and the reception verification unit is on standby.
The test signal from the transmission unit of the transmitting system enters the test verification section from the receiving antenna of the onboard element, and the test verification section verifies the match between the test signal stored in the test signal storage section of its own system and the received test signal. Check that the system is normal. Multiple types of test signals are stored in the test signal storage unit, and the transmitting system can notify the signal type along with the test notification, and the receiving system retrieves the test signal corresponding to this signal type from the test signal storage unit. Verify. One of the test signals includes one in which l and 0 are inverted at each bit position, and when testing, all digits are tested by ensuring that l and 0 are inverted at each bit. That is, the transmission system, which is one of the plurality of transmission units, directly transmits one or more types of test signals to each transmission unit via a line in advance, and then performs the test wirelessly. The transmitting system sends an inspection signal to the onboard vehicle within a predetermined time,
Each transmission unit receives the test signal and compares it with the test signal stored in itself, and checks the normal operation of each transmission unit and the entire transmission unit by comparing the test signal with the predetermined time. If a test signal is not transmitted from the transmitting system within a predetermined time or if the test signals do not match, there is an abnormality in the transmitting system or the relevant receiving system, and the system with the abnormality is removed from the system after considering the results of other systems. Will have to wait for repair. “Example” An example of the present invention will be described below based on the drawings. Figures 1 and 2 show an embodiment of the present invention. As shown in Figure 2, the train information transmission device IO is a transponder system that transmits information through wireless communication between a beacon A installed on the ground and an onboard B installed on the train. ．． I system. The train is equipped with transmission units 20a, 20b, and 20c that constitute a plurality of systems, such as the (1) system and the Tn system. The transmission units 20a, 20b, and 20c all have a common configuration that can be replaced with each other, and include a transmission modem Tx for transmitting signals from onboard the vehicle, and #! It has a reception modem Rx that receives instruction information from above, and a control unit 30 and I/021 that control various functions of the train including reception and transmission, and are connected to each other through a direct line 11 and are in normal operation. Normal L/-CHRI, CHR2. It has CHR3. Onboard child B has receiving antenna Bl and transmitting antenna B for inspection.
2 are provided, and reception modems Rx, Rx... are connected to the reception antenna Bl via distribution@22, and engineering system... ■The transmitting modems Tx and Tx of the system are connected. In this example, the transmission output of the m system is suppressed. The control section 30 is configured as shown in FIG. The configuration of the steel section 30 is shown below. , control unit 30
. is a control signal processing unit 3l that issues train control signals based on instruction information from the ground; a status determination unit 32 that determines whether or not the time unit becomes a transmission system that issues a test signal;
It has a test signal storage section 33 for storing test signals, a test transmitting section 40 for transmitting test signals, and a reception verification section 50 for conducting tests. The test transmitting section 40 includes a test notifying section 4l that notifies other transmission units of the start of a test before issuing a test signal, and a test notifying section 41 that extracts the test signal from the test signal storage section 33 and sends the test signal to the transmitting modem. The test signal transmitting section 42 transmits the test signal from the Tx via the test transmitting antenna B2. The reception verification unit 50 receives the test notification, and includes a test notification receiving unit 51 that notifies that the signal received by the receiving antenna B1 is a test signal, and a test notification receiving unit 51 that receives the test notification from the test transmitting antenna B2.
The test signal storage section 52 includes a test verification section 52 that verifies the match between the test signal received by the receiving modem Rx via the receiving antenna Bl of the test signal storage section 33 and the test signal stored in the test signal storage section 33. A plurality of types of test signals are stored in the test signal storage unit 33, and the plurality of test signals 11W4 include those in which l and 0 are inverted at each bit position. Next, the effect will be explained. The train information transmission system 1110 is connected to the ground switch A installed on the ground.
This system transmits information through radio communication between the train and the onboard vehicle B installed on the train, and controls the operation of the train. A plurality of transmission units 20a, 20b, 20 provided on the train
All units c have common components, and the #1 determination unit 32 determines whether or not its own unit will be the inspection signal transmission system by looking at the installation position, preset order, etc. ing. ■The transmission modem Tx of the transmission unit 20a of the system has contact rl because the normal relay CHRI is outputting the normal output.
, r2 to onboard child B. At this time, ■
The output of the transmission modem Tx of the transmission unit 20b of the system is grounded from contact r3 via a dummy load. The l-system transmission unit 20a at the top becomes the transmitting system, and the other transmission units 20b and 20c serve as the receiving system. Furthermore, the l-system transmission unit 20a also receives data at the same time. After the role of each system is determined in this way, the control signal processing section 3l receives instruction information from the ground transducer A via the receiving antenna Bl and receiving modem Rx of the onboard transducer B and processes it. , each of the three transmission units 20a, 20b, and 20c provided in the train issues a control signal. A plurality of control signals emitted from each transmission unit 20a, 20b, 20c are determined by majority vote or a master-slave relationship, and train operation is controlled. Furthermore, a communication signal S2 can be transmitted from the train to the berm A if necessary. Since operation instruction information is provided intermittently, equipment inspections are performed at times when operation control is not in progress. The inspection is performed as follows. The transmission unit 20a, which has become the transmission system, sends a message from the inspection notification section 41 to other transmission units}20b, 20 before emitting the inspection signal.
The test signal transmitting section 42 directly notifies the test signal c via the line 11 that the test has started, and after this test notification, the test signal transmitting section 42
3 and transmits the test signal S3 to the test transmitting antenna B2 via the transmitting modem Tx. As shown in Fig. 3, the inspection notification is issued from either system depending on the conditions of normal relays CHRI and CHR2 of system ■ and system ■. If the system is normal, the system will not issue an inspection notification. In Figure 3, among the signal connection parts, the parts indicated by small black circles are connected by real connections, and the parts from which signals are output from the engineering system and the system ■ via the white circles are connected to one system. This means that when one system is operating, the other system is not operating. The inspection notification is to transmit the type of the inspection signal S3, and each system thereby knows the hearsay type and the start of the inspection. The system that sent the notification will also receive the inspection notification and become aware of it. ! Since the system is normal, the receiving modem Rx of the receiving system transmission units 20b, 20c and the receiving modem Rx of the transmitting system transmission unit 20a receive the test signal S3 from the receiving antenna Bl. In each transmission unit, the test notification reception unit 5l receives the test notification and instructs that there is a test, and the reception verification unit 50 is on standby. The test signal S3 from the transmitting unit 20a of the transmitting system enters the test signal S3 from the receiving antenna Bl of the onboard child B, and the test signal S3 is input to the test signal S3 from the test signal storage IiI33 of the own system. Verify that the system is normal by testing the match. A plurality of types of test signals are stored in the test signal storage section 33, and the transmitting system can notify the signal type along with the test notification, and the receiving system stores the test signal according to the signal type in the test signal storage section 33. Take it out and compare it. One of the test signals includes one in which l and 0 are inverted at each bit position, and when testing, all digits are tested by ensuring that l and 0 are inverted at each bit. Organizing the above effects, multiple transmission units 20m, 20b,
The transmission system, which is one of the parts 20c, directly transmits one or more types of test signals S3 via the line l1 in advance, and then performs the test wirelessly. The transmission system transmits a test signal S3 from one transmission unit to the onboard child B within a predetermined time, and each transmission unit receives the test signal S3, compares it with the test signal stored in itself, and performs a predetermined signal. The normal operation of each transmission unit 20a, 20b, 20c and the entire transmission unit is confirmed by checking the time and the test signal. ■If the transmission unit 20a of the system fails, the normal relay CHRI will no longer output a normal output, and the transmission modem Tx will open the contact ``l'' and connect to the onboard terminal B.
The output of the transmission modem Tx of the system transmission unit 20b is connected to the onboard terminal B through contacts r3 and r4. Also, if the test signal S3 is not transmitted from the transmitting system within a predetermined time or if the test signals S3 do not match, there is an abnormality in the transmitting system or the relevant receiving system. It will be removed from the system and will be waiting for repair. "Effects of the Invention" According to the train information transmission device 1 and the information transmission device verification method according to the present invention, the on-board information transmission device is a multiple system,
By making it possible to confirm normal operation by emitting inspection signals frequently, failures can be detected early.
Since countermeasures can be taken quickly, serious failures will not occur, resulting in an information transmission device with improved reliability, and verification can be performed easily.
