Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a crossover device for a rail vehicle.
[0002]
[Prior art]
In the conventional railway vehicle, as shown in FIG. 2, the train passing electric control wiring 1 is routed over the entire length of the train when the electric signal in the train necessary for the entire train is passed. The control wiring 1 is necessary for each signal, and a multi-core electrical connection plug 3 is provided at the end of the train passing electric control wiring bundle of each vehicle 2 bundled with a plurality of trains. When the wiring bundle crosses between the adjacent vehicles 2, 2, the electric connection plugs 3 between the adjacent vehicles 2, 2 are connected by an inter-vehicle electric connection line 4.
[0003]
However, in this structure, when the number of train passing electrical control wires 1 increases, the electrical connection plug 3 becomes large. Also, depending on the case, it may occur that the train passing through the planned electrical connection plug 3 does not completely enter the electric control wiring 1, and in such a case, the circuit to be introduced is connected to the electrical connection plug 3. In some cases, I had to give up because of the number of cores.
[0004]
As a countermeasure against this, as shown in FIG. 3, there is one in which a signal transmission device 5 is mounted on each vehicle 2 and the train passing electric control wiring 1 and the inter-vehicle electric connection line 4 of the entire train are replaced by serial communication.
[0005]
[Problems to be solved by the invention]
However, in this structure, the circuit of the entire train must be changed according to the signal transmission device, and the signal transmission device itself is expensive.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 shows a block diagram per train passing electrical control wiring. The crossover device 10 between the A vehicle and the B vehicle has the same configuration on the A vehicle and the B vehicle, respectively. Therefore, the description will be made with the vehicle mounted on the A vehicle.
[0009]
The parallel-serial conversion circuit 12a connected to the train passing electric control wiring 11a includes a circuit switch 13a connected to a power source and a diode 14a inserted from the circuit switch 13a toward the train passing electric control wiring 11a. A logic circuit 15a for creating a control signal for the circuit switch 13b of the B vehicle from the open / closed state of the circuit switch 13a of the own vehicle and the pressurized state of the train passing electrical control wiring 11a, and the control signal in parallel-serial A transmitter 18a that converts and transmits the signal to the receiver 16b of the parallel-serial conversion circuit 12b of the B vehicle via the inter-vehicle electric connection line 17a, and an inter-vehicle electricity from the transmitter 18b of the parallel-serial conversion circuit 12b of the B vehicle. A receiver 16a that receives a control signal transmitted via the connection line 17b and performs serial-parallel conversion and a signal voltage level conversion circuit. It is composed of a 19a.
[0010]
In this embodiment, a solid state relay is used for the circuit switch 13a. Further, other train passing electric control wirings are connected to the receivers 16a and 16b and the transmitters 18a and 18b, respectively.
[0011]
The circuit operation of the inter-vehicle electrical signal exchange between the A vehicle and the B vehicle of the crossover device 10 configured as described above will be described below.
[0012]
(1) When the train passing electrical control wiring 11a of the A vehicle is pressurized by turning on the connected switch or the like, and the train passing electrical control wiring 11b of the B vehicle is not pressurized, the train of the A vehicle An AND operation is performed by the logic circuit 15a of the A vehicle and the transmitter 18a performs parallel-serial conversion to the circuit of the B vehicle by applying the passing electrical control wiring 11a and the fact that the circuit switch 13a of the A vehicle is not ON. An ON command signal for the switch 13b is issued. This ON command signal is transmitted to the receiver 16b of the B vehicle via the inter-vehicle electric connection line 17a, and the receiver 16b of the B vehicle performs serial-parallel conversion to turn on the circuit switch 13b of the B vehicle. The train passing electric control wiring 11b of the B vehicle is pressurized. At this time, in the B vehicle, the circuit switch 13b is turned on. Therefore, if AND is applied to the train passing electric control wiring 11b of the B vehicle, the circuit opening / closing of the A vehicle is performed from the logic circuit 15b of the B vehicle. There is no ON command signal for the device 13a.
[0013]
(2) When the train passing electrical control wirings 11a and 11b of both the A and B vehicles are pressurized by turning on the connected switches or the like, the logic circuit of the previously pressurized vehicle has priority, After that, it becomes the same as the state of (1).
[0014]
(3) When either switch is turned off from the state (2), the state transits to the state (1).
[0015]
As described above, since the electric signal in the train between the A and B vehicles is a serial signal, the inter-vehicle electric connection lines 17a and 17b between the A and B vehicles may be small and have a small number of cores. It is possible to flexibly respond to increase / decrease of internal electric signal, and furthermore, the power of the signal of each vehicle is supplied from the power supply of the own vehicle, and since the power of the signal is different for each vehicle, the same electric signal crosses each vehicle. Therefore, it is possible to prevent a decrease in reliability due to a plurality of electrical connection plug contacts entering one electrical signal. In addition, the power source that pressurizes the train passing electrical control wires 11a and 11b of each vehicle is the power source of each vehicle, and the power source of the own vehicle does not drive the parallel-serial conversion circuit of the other vehicle. Vehicles having different voltages can be connected to each other.
[0016]
【The invention's effect】
As described above, the crossover device for a railway vehicle according to the present invention performs parallel-serial conversion on the voltage pressurization state of the train passing electrical control wiring of one vehicle and transmits it to the other vehicle by the serial transmission method. In addition, since the parallel-serial conversion circuit for serial-parallel conversion is provided in the other vehicle, the inter-vehicle electrical connection line can be small with a small number of cores, and can flexibly respond to the increase or decrease of the electric signal in the train. In addition, since the power source of the signal is different for each vehicle, the same electric signal does not cross each vehicle, so that it is possible to prevent a decrease in reliability due to a plurality of contacts of the electric connection plug. In addition, a circuit switch such as a solid state relay is inserted between the train passing electric control wiring and the power source of each vehicle, and the train passing electric control wiring of the own vehicle is pressurized. Then, when the circuit switch of the own vehicle is in the closed state, the logic is set to control the circuit switch of the counterpart vehicle, and the parallel switch is generated from the circuit switch of one vehicle and converted into the other vehicle. The circuit switch of the other vehicle is controlled so that the pressurized state of the train passing electrical control wiring of each vehicle is the same by the signal transmitted to the other vehicle. Since the conversion circuit is not driven, vehicles having different power supply voltages can be connected to each other.
