2. Description of the Related Art Hitherto, a route of a train or a vehicle has been secured by an interlocking device. In the interlocking device, a signal handler inputs route information in response to a request from a vehicle driver. The route information is input to the processing device via the input / output device by operating the display control panel at the station signal handling place. The processing device operates the switch, the switching sign, and the traffic light in accordance with the input signal via the input / output device to secure the course of the vehicle.

[0003] The vehicle position is detected by a track circuit as shown in FIG. 2 when the vehicle travels on the route thus secured. As shown in the figure, two terminals of the power supply 1 are connected to rails 2 and 2 on both sides, and the rails 2 and 2 are connected to a coil of a relay 4.

When the vehicle 3 is not in the conduction section of the rails 2 and 2, current flows from the power supply 1 to the coil of the relay 4.
When the vehicle 3 is present, the rails 2 and 2 are short-circuited, and no current flows through the coil of the relay 4. Thus, the presence or absence of the vehicle is detected by turning on / off the relay 4. By the above-mentioned track circuit, when the scheduled passage of the vehicle is confirmed,
The interlocking device enables the switching of the switch and the like for the next course configuration.

[0005]

When the vehicle position is detected by the above-mentioned conventional track circuit, the presence or absence of the vehicle can be detected but the vehicle cannot be specified. Therefore, it is inconvenient to manage the operation of a specific vehicle when many routes congest.

[0006] Further, since the track circuit does not notify the vehicle itself of passing a specific point, it is not possible to directly perform an alarm or stop operation for an erroneous start or overrun.

[0007] Further, in a light-weight vehicle such as a maintenance vehicle, there is a disadvantage that the function as a driving safety facility cannot be satisfied because the rails cannot be sufficiently short-circuited by an axle.

[0008] The present invention has been made in view of the above points, and an object of the present invention is to provide an on-vehicle track capable of reliably monitoring and controlling the operation of a vehicle on a route constituted by a specific vehicle. It is to provide a position detecting device.

[0009]

According to the present invention, there is provided an on-vehicle on-line position detecting apparatus, comprising a plurality of ground terminals arranged corresponding to a specific position on a track, and discriminating the ground children when passing near each ground child. The vehicle is provided with a vehicle upper child that communicates a signal to be transmitted to the ground child, and a control device provided in the vehicle stores ground child discrimination information from the vehicle child in a storage device when the interlocking device sets a course. It is configured to distinguish between normal progress and abnormal progress in comparison with data.

Further, in the vehicle on-rail position detecting device, the vehicle or train is provided with the vehicle upper and lower parts at the forefront and rearmost parts.

Further, in the vehicle on-rail position detecting device, an automatic alarm device in the train is operated at the time of overrunning, early repositioning, erroneous start, start of course, or erroneous setting of erroneous course, to reduce the speed of the vehicle or train, Alternatively, the vehicle is configured to stop.

Further, in the above-mentioned on-vehicle on-line position detecting device, an automatic alarm device in the train is activated at the time of an overrun, an early return, an erroneous start, a start of a course, or an erroneous run setting of an erroneous route, thereby alerting the driver in the train. It is configured to emit.

Further, in the above-mentioned on-vehicle on-line position detecting device, information on a ground vehicle passed from a moving vehicle or a train is transmitted to a monitoring device on the ground by wireless communication.

[0014]

According to the vehicle on-rail position detecting device of the present invention, the set order of passing the ground on the route is stored as data, and when the upper child provided on the vehicle passes near each ground child. It is confirmed that the order of the ground child matches the stored order of the ground child.

When the passed ground does not match the stored data, it is determined that the vehicle is traveling abnormally, and the automatic alarm device is operated to reduce or stop the speed of the vehicle or train, or to issue an alarm to the driver. In this way, overrun, early return,
Accidents due to erroneous starting, start of course, etc. are prevented.

[0016] By transmitting the information of a ground child passing from a moving vehicle or a train to a monitoring device on the ground by wireless communication,
The route operation state of the vehicle is grasped on the ground. In that case, if you have a vehicle upper and lower part of the train or train,
It is possible to identify whether a specific point is in the middle of passing through the train or the end of passing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An on-vehicle position detecting apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a vehicle on-rail position detecting device according to an embodiment of the present invention.
As shown in FIG.
A control device 8 and a wireless device 9 are arranged. The storage device 12 can be connected to the interlocking device 10 on the ground and the control device 8 on the vehicle.

The upper child elements 6, 6 are arranged at the front and rear parts of the vehicle 3, radiate microwaves to the ground element 5 arranged on the track, and the ground element 5 is fed by a battery and identifies itself. The signal is modulated by the microwave and returned to the upper child element 6.
The upper armature 6 outputs the received microwave signal to the reader 7. The reading device 7 demodulates the input signal, and
Is output to the control device 8.

The control device 8 compares the input signal for identifying the grounding element 5 with the data in the storage device 12 and outputs a signal for operating an automatic alarm device (not shown).
It communicates with the interlocking device 10 via the radio 9 on the car and the radio 11 on the ground.

By operating the display control panel, the interlocking device 10 switches the traffic light, the exchange sign, and the switch to set the vehicle route. In addition, the storage unit 12 stores the data of the set order of passing the ground on the route set at that time.

Next, the operation of the on-vehicle position detecting device will be described. Before the vehicle is operated, the interlocking device 10 stores the order (passing route) of the ground child at the destination in the storage device 12 for each operation. The storage device 12 storing the passing route is detached from the interlocking device 10 and connected to the control device 8 on the vehicle.

Next, the control device 8 transmits a request for confirming the passing route via the wireless device 9. The interlocking device 10 is a wireless device 1
When the confirmation request is received via the control unit 1, the passing route is transmitted to the control device 8 again. The control device 8 compares the previously stored passing route with the sent passing route, confirms it, and transmits a response to the interlocking device.

When the confirmation of the passing route is completed, the interlocking device 10 changes the point and configures a target course. When the configuration is completed, the interlocking device 10 transmits the configuration completion to the control device 8, and in response to this, the vehicle starts operating. If these confirmation requests are not made, or if the vehicle is operated during the confirmation, the control device 8 recognizes that the vehicle has erroneously started when the upper child passes the first ground child, and operates the automatic alarm device to activate the inside of the vehicle. Warning the driver and stop the vehicle.

After the confirmation operation is completed, the vehicle advances, and when the identification information of the first ground child installed on the track is input, the control device 8 compares the identification information with the passage route. If the two do not match, the control device 8 recognizes that a wrong course has been set and activates an automatic alarm device to warn the driver in the vehicle and stop the vehicle.

If the identification information of the ground child and the passage route match, the control device 8 transmits the passage information to the interlocking device 10 after waiting for the input of information from another vehicle child. The interlocking device 10 displays the vehicle position on the display control panel based on the information.

When a ground element that does not coincide with the passage route is read while passing through a plurality of ground elements, the control device 8 recognizes that the route is starting and activates an automatic alarm device to warn a driver in the vehicle and stop the vehicle. .

When the vehicle has traveled the correct route and has read the last ground child, the control device 8 sends a return request enable signal to the interlocking device 10. Therefore, an accident can be prevented because the switching device cannot be changed until the two upper arms read the last ground arm of one passing route.

If the driver erroneously drives the vehicle beyond the final point of the passing route and reads a ground child that is not on the passing route, the control device 8 recognizes that the vehicle is overrunning and operates the automatic alarm device to activate the driver in the vehicle. Warning and stop the vehicle.

After the control device 8 sends a re-request request signal to the interlocking device 10, if the vehicle again operates the next passage route, the control device 8 sends a request for confirmation of the next operation to the interlocking device. After confirming the route configuration, the next operation is performed.

Although the embodiment is constructed as described above, the invention is not limited to this. For example, when the vehicle is short, such as a maintenance vehicle, only one upper arm may be provided.

[0031]

According to the on-vehicle position detecting device of the present invention, the position information of a specific vehicle is transmitted to the interlocking device, and the operation of the vehicle can be monitored.

Further, it is possible to prevent an accident of a vehicle or a train at the time of running abnormally, such as overrun, early return, erroneous start, start of course, and erroneous course setting.

Further, this apparatus can perform the confirmation work conventionally performed before operating the vehicle or the train, and can automatically perform the work.

Further, as shown in the embodiment, when a battery is used as a power source for the grounding element, cable connection is not required and the installation cost is reduced.

Further, it is possible to increase the accuracy of detecting the position of a train or a vehicle by increasing the number of ground elements.
