Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an operation management device for performing automatic train operation management.

[Prior Art] In recent years, an ATS system has been introduced to ensure the safe operation of trains. As shown in FIG. 2, this is composed of a ground device 1 and an on-board device 2. Ground device 1
Is a code processor 10, repeaters 11 ₁ to 11 _n , traffic light 12, instrument box
It is composed of 13 and 14 ₁ to 14 _n ground elements. They are connected by a communication cable, and the code processor 10 encodes signal information such as a display condition input from the traffic signal 12 and transmits it to the repeater. The repeater further transmits the received signal information to the on-board device 2 via the ground element. Code processor 10
In addition to the power-source grounding element that transmits information from the
There are two types of transmitting a fixed telegram set in advance using a power wave described later.

On the other hand, the devices related to transmission / reception of the on-board device 2 are a transmitter / receiver 20, a controller 21, indicator lamp switches 22, a recorder 23, and a brake device 2.
It is composed of 4 and 25 car trains. The transceiver 20 receives information from the ground element and transmits a power wave that supplies power to the non-powered ground element. Further, the telegram from the vehicle is transmitted to the ground, and the telegram received from the ground is code-inspected by the onboard device 2, and the correct telegram is output to each controller of the vehicle. The controller 21 generates a check pattern according to the content of the message sent from the transceiver 20. When the train speed exceeds this pattern speed, a brake command is automatically output. Recorder 23
Records the operating status of each device.

In such a system, the ground signal indication changes as the preceding train runs, so multiple ground devices are installed in one closed section, and the code processors of each ground device repeater belong to each code processor. The plurality of repeaters to be controlled are time-divisionally controlled and polled so that the latest information is sequentially transmitted from the adjacent repeaters. Normally, the distance to the stop signal is transmitted from the ground device 1 to the on-board device 2 so that the train stops before the stop signal, and the on-board device 1 generates a speed stop pattern according to its own braking performance. Then
It is designed to stop before the stop signal to ensure safety.

[Problems to be solved by the invention] In such a system, when the signal is stopped (red), the on-board pattern is brake-controlled so that the train stops before the stop signal. On the other hand, the ground element in front of the red traffic light has the role of releasing the pattern on the car and sending information that allows the train to move forward when the preceding train moves forward and the traffic light changes from red to yellow and green. ing.

Here, the terrestrial device has a plurality of repeaters, and one code processor transmits the signal information to the repeater by time division transmission. Therefore, a certain on-board device runs and receives the signal information from the repeater. After that, the time until the next signal information is received becomes shorter as the number of repeaters increases. That is, the larger the number of repeaters, the closer to continuous control and the closer to real-time transmission of signal information. On the other hand, the larger the number of repeaters, the longer the time required for polling between the processor and the repeaters on the ground side. For this reason, even if there is a signal signal up (red → yellow), it is not transmitted to all the repeaters at the same time, and can be transmitted only when the polling has completed one cycle.

Therefore, if the train stops at a position further ahead of the ground element at the forefront of the closed section as shown in FIG. 3, there will be no ground element at that point, and the updated information cannot be received. The on-board pattern of the train is not updated, and the train cannot run forever.

[Means for Solving the Problem] In order to solve such a problem, the present invention is designed to send signal information only to the last passage section of the train in the closed section.

[Operation] Since the repeater in the passage completion section of the train does not need to perform time-division control, the time-division data supplied to the repeater in front of the train has a shorter repeating period as the train progresses, and the signal display change Immediately transmitted to the car.

[Embodiment] In the conventional apparatus, since a plurality of repeaters and one code processor are time-division controlled for economical reasons, the above-mentioned inconvenience occurs. However, if the location of the train is known, it is not necessary to send data to the repeater behind the train in the closed section where the train exists. In order to realize this, an oscillator is provided in the on-board device, an oscillating signal from the vehicle is received by the ground element, and the reception of this signal is transmitted to the code processor.

When the code processor 10 receives the oscillation signal from the on-board device 2,
The transmission of the time division data is stopped to the repeater in the place before the point where the oscillation signal is received, and the time division data is transmitted only to the repeater in the front of the train. By doing so, it is possible to shorten the supply cycle of the time division data supplied to the remaining repeaters.

Therefore, if there is a train near the ground terminal before the stop signal, the number of repeaters that need to transmit information is one, and the code processor and repeaters have a 1: 1 relationship, and information is transmitted. Very quickly, the traffic signal change is immediately transmitted to the repeater, and the time delay of information transmission to the on-board device 2 is not a problem.

FIG. 1 is a flow chart showing the operation of this invention,
As shown in step 100 _1a , while the on-board oscillation of the n-th repeater is not received by the ground equipment, the n-th step of step 100 _1b is performed.
The signal information at the end is supplied to the n-th repeater,
When the on-vehicle oscillation is received, step _1001b is omitted and the processing of the next step _1002a is performed. The same applies to step _{1002a and} subsequent steps. In addition, 1708 ± 32kHz FSK signal is used for the signal transmission from the ground child to the car child, and 3000 ± 32kHz FSK signal is used from the car child to the ground child.

[Advantage of the Invention] As described above, according to the present invention, the time-division data is transmitted only to the repeater in front of the train passage point, so that the repeat cycle of the data supplied to the repeater near the stop point is It becomes short, and even if there is a change in the signal indication, it is immediately supplied to the repeater, and it has an effect that signal transmission can be performed in near real time.
