Description

Detailed Description of the Invention

[0001]

The present invention relates to a global positioning system [Global Positioning System] for train operation.
Hereinafter, the present invention relates to a GPS train safety device that prevents collisions in train operation using "GPS".

[0002]

2. Description of the Related Art For example, in the case of train operation in a single-track section, which is seen in a conventional example, when the trains going up and down are separated, one of the trains to be separated waits for the opposite train to pass at the nearest station. Was to do. Then, the position of the train is transmitted to a train driver or a staff member of a station by applying a traffic signal, a tablet phone or the like. The same was done when a priority train overtook a regular train even in a double-track section. In addition, CTC [Centralized Traffic cntrol train centralized control device] is implemented in the suburbs of Tokyo and Shinkansen.

[0003]

However, in the above-mentioned conventional example, the train operation is ultimately left to the judgment of the person, and there is a possibility of making an erroneous judgment. In particular, there was a risk that the most redundant accident due to human error would occur when the train schedule was disturbed due to various accidents. Further, in the CTC, transmission and reception of information between each of these trains and fixed bases is mainly made up of signal systems such as wire communication and train guidance wireless, and the ground laying equipment and the like require enormous expenses.

As described above, in the conventional technique, in a quiet section without a CTC such as a single track section, the worst situation caused by an unavoidable human error is a head-on collision accident, which causes many human lives. It cannot be robbed. Also, a rear-end collision cannot be overlooked.

Therefore, in the present invention, in order to eliminate the danger caused by these human error, the GPS from the GPS satellite is used.
Applying GPS, which can accurately know the received position by receiving and calculating radio wave signals, forms a system for train operation without man-made judgment. GP
The purpose is to provide an S train safety device.

[0006]

In order to achieve the above-mentioned object, the present invention provides a GPS receiver capable of receiving a radio wave signal from a GPS satellite and accurately obtaining the received position, and a GPS receiver from this GPS receiver. A transmitter that receives the position information of the above and sends this information to the outside as a transmission radio signal, and a drive transmission mechanism that transmits a signal that controls the driving of the train by receiving the instruction radio signal from the command means for general train operation, A plurality of trains each equipped with a drive device for driving and controlling a train in response to a signal from the drive transmission mechanism are operated on the track, and the transmitter of each train is used as a command means for general train operation in the operation on the track. When receiving position information from, when competing oppositely or competing for passing,
A central control unit that makes a decision to prevent a frontal collision or a rear-end collision, and sends a command radio signal for priority departure or absolute stop at each train departure point to each of the corresponding trains to form a fixed base. And a display device that receives a command radio signal from the central control device to each train at each related station and displays it.

[0007]

According to the present invention, since the train driver makes a wrong decision and tries to start the train, the train does not move unless directed by the central control unit. It is possible to avoid head-on collisions of trains in sections or rear-end collisions in all sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a GPS according to an embodiment of the present invention.
It is a block diagram showing a circuit configuration of a train safety device.

In FIG. 1, reference numerals 1, 7 and 8 denote trains [each of these trains has the same elements mounted therein, and the train 1 is disclosed here]. The term "includes all trains of the so-called train, not to mention trains operating on tracks in the ordinary sense." Reference numeral 2 is a GPS receiver installed in the train 1, 3 is a driving device for operating the train on the track, 4 is a transmitting device for transmitting a signal of the position obtained by the GPS receiver 2, and 5 is a central control device 6. It is a drive transmission device for sending the instruction signal sent from the drive device 3 to the drive device 3. Further, as described above, the GPS receiver 2, the driving device 3, the transmitting device 4, and the drive transmitting device 5 are also provided in the trains 7 and 8. Reference numeral 6 is a central control unit for judging the position information sent from the trains 1, 7, 8 and sending an instruction signal to the drive unit 3 of each train to stop, start or accelerate or decelerate. Sending operation command radio signals to each train,
It is a commanding means for general train operation that controls all of these operations, such as CPU (Central Processing Unit), ROM, RAM
Etc. 9 and 10 are based on the information given from the central control unit 6 and display the information to inform the train driver or staff of the train at the nearest station to the movement status of the trains before and after the station and the signals of stop and departure. It is a display device.

The operation of the GPS train safety device configured as described above will be described below.

Now, between the A station and the B station on the single track section,
Train 1 stops at station A and train 7 stops at station B.
Both trains are in a state of facing each other. Here, since the train does not operate on the line between the A station and the B station, the central control device 6 issues a departure command to the train 1 and a stop command to the train 7, or a stop command to the train 1 and train 7. You can issue a departure order to. Then, after the departing train arrives at the station of the stopped train and the central control device 6 determines that it is safe, it issues a departure command to the driving device 3 of the stopped train. While the train is running between the stations A and B on the single track, the display devices 9 and 10 of each station display the position of the train and the stop signal from the traffic light.

Further, when both trains take the same traveling direction in the single-track section or the double-track section and the train 1 of the priority train overtakes the train 7 of the ordinary train at the B station, the same means can be taken.

In other words, the central control unit 6 constantly operates each train 1,
The current position information obtained by the GPS receivers 2 mounted on 7, 8, ... Is collected by receiving information radio waves from the respective transmitters 4, and the current state of each train at that time. Then, a sequential program stored in advance in the storage means is accessed to determine the safest and most efficient operation command for each train, and the train command is used as an operation command radio signal for each train 1, 7, 8, ... to the drive transmission device 5 and the display devices 9, 10 ... Therefore, the train operation cannot be done by the driver or the staff of the station, and there is naturally no error in human judgment.

[0015]

INDUSTRIAL APPLICABILITY As described above, the present invention automatically and simply takes accurate current position information of the train by GPS and sends it to the central control unit of the fixed base as a radio signal to comprehensively evaluate the situation of each train. By introducing a system that makes a direct judgment to the driving device and directly instruct the drive device, it is possible to avoid a train collision accident in a single-track section caused by an error in human operation or an error in judgment. Can play.
