Indicates.

That is, the rear device control method (S10) is continuously performed to detect whether or not the transmitted signal is received, and the back cover 26 lights up, whether the power is abnormal or charged, the pressure of the braking tube, The display unit 12 displays information about the acceleration of the rear vehicle and whether or not the truck is disconnected.

At this time, when the power is not normal or the communication state is not normal as a result of performing the received signal analysis step (R12), perform the alarm signal generation step (S13) to generate an alarm signal through the alarm (11) When it is determined that the connection of the vans is released, an alarm signal is generated and at the same time, a control signal is inputted to the train protection radio device to generate an alarm signal indicating that the van is departed from its formation. Alert signal generation transmission step (S14) is performed.

In addition, after the alarm signal generation transmission step (S14) is performed as a result of determining that the connection of the truck is released and generates an alarm signal through the alarm 11 and the train protection radio device, the cab operation switch 14 By continuously detecting whether the emergency braking switch is pressed, if it is determined that the emergency braking switch is pressed, the operation of the train is stopped by inputting a control signal to the emergency braking of the train.

Therefore, it is possible to detect whether the vans are disconnected quickly and accurately, to prevent subsequent collisions with trains due to the disconnection of the vans, and to reduce the size and weight due to the provision of a self-powered device. It will be possible.

11 shows an example of a signal transmission format.

However, in the above embodiment, the self-generating device is configured using a solar cell composed of a solar integrated plate and a converting device, but the self-generating device can be configured by using a generator using the rotational force of the wheel. .

In addition, in the above embodiment, the acceleration detection of the rear vehicle is detected using an acceleration sensor, but it can be understood that it can be configured through a GPS receiver or an ultrasonic sensor.

In addition, in the above embodiment, the braking of the train is dependent on the operation of the emergency switch when disconnecting the truck, but if the emergency switch is not operated so that a predetermined time elapses after determining that the truck is disconnected, the ATS It is to be noted that by inputting a control signal to the train can be configured to automatically stop the operation of the train.

In the above embodiment, when the ID of the rear device is registered in the cab device, the registration of the cab device is automatically performed through the wireless communication with each other and the ID of the cab device is automatically registered. Make sure you can use it.

That is, the cab apparatus may be assigned to the cab apparatus by acknowledging the received ID when the ID of the rear apparatus is received without assigning a unique ID to the cab apparatus.

Then, the cab device detects and infers only a signal having a registered ID.

In addition, after the liquid crystal display device and the operation button (consists of adding a number or letter button to the rear operation switch) and a storage means (memory) are installed in the rear device, the cab device ID and the rear device ID are registered. The cab ID can be registered by manipulating it in the rear device.

Then, when the signal is transmitted from the rear device, the cab device ID is transmitted and transmitted, and the signal interference with another device can be excluded by receiving only the signal having the cab device ID.

On the contrary, it is noted that the cab apparatus can communicate with the rear apparatus by inputting the rear apparatus ID.

In addition, the confirmation switch, or ID registration switch, because there may be a plurality of cab devices responding to the transmission of the ID from the rear device, for example, there are a plurality of locomotives in the receiving place, such as the base window, There may be several cab units, so use them at this time.

Alternatively, if the rear-end device completes self-casting and transmits an ID, it detects a signal from the cab device that responds to it, and if there is more than one signal, the ID registration can be found again. Put it.

In other words, the waiting time for registering an ID is short and does not occur frequently, and the cab responds to the registration of the ID through wireless communication using the fact that it is unlikely to be registered in two or more cab devices at the same time. If there is more than one signal from the device, it is necessary to register again.

However, the method of registering the rear device to the cab using wireless communication is not limited to this.

 As described above, the present invention "train rear end detection device and its control method", in particular, after giving a unique ID number (IDENTITY NUMBER) to each of the rear unit and the cab unit, the rear unit is mounted on the truck and the cab When connected to the device, the ID number of the rear device can be automatically registered in the cab device via wireless communication.
