[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a ground member a according to an embodiment. The same reference numerals are used for the same components as those of the conventional ground member shown in FIG. 2, and these components are not described. Due to duplication, only new parts will be described with different reference numerals.

The message setting unit 10 corresponds to a G indication message ROM 11 corresponding to the G indication of the signal S, a Y indication message ROM 12 corresponding to the Y indication of the signal S, and an R indication of the signal S. An R present message ROM 13 is provided, and predetermined address bits (A) of these message ROMs 11 to 13 are provided.
0 to A6) are supplied with the DC power generated by the power generation unit 1 via the readout circuit 14, and are configured to set predetermined bits.

In FIG. 1, reference numeral 15 denotes a checking circuit included in the message setting unit 10, which inputs and checks the output of each of the message ROMs 11 to 13, and outputs the result of the checking to each of the message ROMs 1.
It is configured to be able to transmit to predetermined input terminals (address bits A7) 1 to 13 respectively. The checking circuit 15 is also configured to output a signal to the modulation circuit 31 to stop its function.

When the power generated by the power generation unit 1 is supplied to the power supply pin (Vcc) and the traffic light S indicates the G indication, the G indication message ROM 11 reads the indication relay R (G). A predetermined message indicating that the traffic light S is the G indication via the lifting (ON) contact of the GR) is transmitted to the first bit (D0).
Are output to the modulation circuit 31 and the inspection circuit 15. In addition, this G present telegram RO
From the second bit (D1) of M11, a predetermined message indicating that the traffic light S is the Y-state is output to the checking circuit 15.

When the power generated by the power generator 1 is supplied to the power supply pin (Vcc) and the traffic light S indicates the Y indication, the Y indication message ROM 12 stores the indication relay R ( A predetermined message indicating that the traffic light S is in the Y position via a lifting (ON) contact of YR) is transmitted to the first bit (D0).
Are output to the modulation circuit 31 and the inspection circuit 15. In addition, this Y present telegram RO
From the second bit (D1) of M12, a predetermined message indicating that the traffic light S is the R signal is output to the checking circuit 15.

When the power generated by the power generation unit 1 is supplied to the power supply pin (Vcc) and the traffic light S indicates the R indication, the R indication message ROM 13 stores the indication relay R ( A predetermined message indicating that the traffic light S is the R signal can be output from the first bit (D0) to the modulation circuit 31 and the checking circuit 15 via the falling (OFF) contact of GR, YR). It is configured. Also, from the second bit (D1) of the R present message ROM 13, the signal S
Is configured to be able to output a predetermined message indicating that G is the G indication to the checking circuit 15.

In the above-mentioned grounding element, the signal S
Indicates a G presentation. Then, when the train approaches the ground child, each of the message ROMs 11 to 13 is supplied with electric power from the electric power generation unit 1 and enters an operating state.

When each of the message ROMs 11 to 13 is normal, the checking circuit 15 matches the message output from its own message ROM and the adjacent message ROM.
It is determined that the OMs 11 to 13 are normal. At this time, the electronic message NG signal is not output to each of the electronic message ROMs 11 to 13. Therefore, the modulation circuit 31 has a G present message R
A normal predetermined electronic message indicating that the traffic light S indicates the G indication is input from the OM 11, and the electronic message is transmitted to the vehicle via the transmission coil 33.

By the way, if there is a message that does not match,
For example, when a mismatch occurs between a predetermined message output from the Y-display message ROM 12 and a predetermined message generated and output by the G-display message ROM 11, the signal of the message NG is output from the checking circuit 15. It is input to the address bits (A7) of each of the message ROMs 11 to 13.

When a signal of a telegram NG is input to the address bit (A7), the telegram output from each of the telegram ROMs 11 to 13 is changed to a telegram in which a bit indicating that it is a check NG is set. Accordingly, a message input from the G-presentation message ROM 11 to the modulation circuit 31 is also a message indicating the check NG, and this message is transmitted to the upper side of the vehicle via the transmission coil 33.

On the vehicle receiving the message indicating the check NG, it is possible to detect from the received message that an abnormality has occurred in the ground child.

The electronic message in which the bit indicating the above-mentioned check NG is set is the first bit (D0) of each of the electronic message ROMs 11 to 13.
And the second bit (D1) are input to the checking circuit 15 and checked. Then, when a mismatch occurs in the checking, a failure of the checking circuit 15 itself can be considered. In this case, a signal for stopping the function of the modulation circuit 31 is output from the checking circuit 15. Modulation circuit 3
1. When a function stop signal is input from the checking circuit 15,
The modulation process is stopped, and therefore, transmission of all messages from the transmission coil 33 is stopped.

When the transmission of the telegram from the transmission coil 33 is stopped, that is, when the transmission of all the telegrams from the ground child is stopped, the train travels a predetermined distance from a predetermined point, and the train stops on the ground. Since information cannot be obtained from the child, it is possible to detect that the child on the ground is down. Note that the train is configured such that even if one ground child is down, train control is performed based on information from another adjacent ground child.

[0025] The fact that a ground mismatch has occurred and that the vehicle has gone down due to the occurrence of an abnormality is detected on the vehicle, so that the ground child can be recovered from failure based on the detection.

The above-described control operation is performed when the traffic light S is in the G display, but is the same when the traffic light S is in the Y display or the R display.

In the above-described example, the ground power supply is the power generation unit 1.
This is a case of a non-powered system provided with a power supply system, but may be a case of a power supply system provided with a power supply on the ground.

[0028]

According to the present invention, the configuration of the grounding element with a message checking function according to the present invention includes a predetermined message corresponding to each indication of the traffic light and a predetermined message corresponding to one other indication other than the corresponding indication. A plurality of message ROMs capable of outputting a message; a matching means for matching two identical messages output from the plurality of message ROMs; Select a specific message corresponding to the announcement and send it out to the car.
Since the transmission means includes a transmission means for transmitting a predetermined message to which a predetermined signal indicating that there is a collation mismatch between the messages to the vehicle, the failure of the grounding element can be easily detected. In addition, when the verification of a message to which a predetermined signal indicating that there is a verification mismatch does not match, when a prohibiting means for prohibiting transmission of the message on the vehicle is provided, it is possible to further enhance the reliability of the ground child. it can. In the case where the collation does not match, when the prohibition means for prohibiting the transmission of the electronic message on the vehicle is provided, the reliability of the grounding element can be further improved.
