FIG. 1 shows a test method for a train control data transmission network according to an embodiment of the present invention. MSC in diagram
is the train master controller and cab equipment (both are installed in the train cab), TCW
is a through line, and the control system of current trains is the same. Here, equipment EQU1 of each power unit,
EQU2 is connected to the lead-through line via the normally-on contacts (NC contacts, also known as b contacts) of selection relays FDR1 and FDR2, and is connected to the normally-off contacts (NO contacts, also known as a
It is connected to the parallel interface output terminals POF1 and POF2 of the transmission stations ST1 and ST2 of the train control data transmission network VLN via contacts).
The output level of POF1 and POF2 shall be the same as the output level of the lead-through line. Normally, the level of the train control data transmission network VLN is 5V, and that of POF1 and 2 is DC100V. On the other hand, the pull line TCW is
Connected to parallel input interface terminal PIF0 of VLN transmission station STO near the driver's cab.
This input level is normally the same as the lead-in line.
Since it is DC100V, relays etc. become fail-safe interface elements.

A signal FDS is passed to the FDD, which is a pulse that, for example, if the VLN is of a cyclic transmission type, is output while the transmission cycle is continuing and stops when the transmission is interrupted. Therefore, in the FDD, this is AC amplified and the switching relay excitation lead-in line FDW is excited only during normal conditions. As a result, if VLN continues transmission normally, devices EQU1 and EQU
2 is given a control signal from the network,
When a VLN abnormality occurs, relays FDR1 and FDR2 switch to open mode, and a control signal is then applied.

ない。 Here, since the NC contacts of the switching relays FDR1 and FDR2 are on the equipment side, in the event of disconnection of the relay coil or disconnection of the switching lead-in wire FDW, the switching relays FDR1 and FDR2 switch to the conventional lead-through side, and are fail-safe. It is also fail-safe against power outages to the VLN and abnormality detector FDD. Furthermore, especially when the VLN uses a cyclic transmission method, the FDD can be used as a fail-safe AC amplification. In this embodiment, furthermore, since each power unit simultaneously switches to the lead-through line FDW side due to a transmission abnormality, there is no variation among the units.

えられる。 FIG. 2 shows another embodiment of the present invention in which a transmission abnormality is detected at each transmission station and the flow of control signals can be switched from the network VLN to the through line TCW side. The transmission abnormality here is often related to noise. Data transmission network VLN is
As mentioned earlier, it operates at a signal level of 5V, but the train's main circuit control system handles voltages as high as 1500V. Therefore, the data transmission network VLN is likely to pick up noise generated from these. In this embodiment, the transmission station that has detected a transmission abnormality uses a method of short-circuiting the switching lead-in line FDW to ground. SCC1-2 are short circuits of FDW. For short circuits, if you use relay NC contacts, FDR1,2
As in the case of , it can be made failsafe. In addition,
A protection circuit against short-circuit current is required on the FDD side, but it can be protected with a normal circuit protector, so it is not shown. Now, when the transmission station detects a transmission interruption, an error detected by a test bit (parity error, periodic hole length inspection error, etc.), or an interlock error in parallel output due to a bit error, the switching reference is activated by the short circuit SCC. Short-circuit the through wire FDW. In this way, the switching relays FDR1 and FDR2 are no longer excited and are turned off, so that the control signal for the device is given from the lead-in line.

できる。 In this embodiment, if the time from occurrence of a transmission abnormality to switching to the feed line side is long, there is a risk that line breakers and contactors of the train drive main circuit may open. This can be solved by slowing down the abnormality detection speed of the network and using high-speed relays in the FDW to make the switching speed faster than the operating speed of the main circuit breaker and contactors.
