[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train running simulation device effective for confirming the operation of on-board devices such as an ATS device and an ATC device which control the running of a train according to information from ground equipment.

[0002]

2. Description of the Related Art In order to develop an on-board device such as an ATS device or an ATC device, or to clarify the cause of any trouble occurring in an already installed on-board device, etc.
There is a train running simulation device that can check the operation state of an on-board device without actually running the train by simulating the state in which the train is running.

[0003] A conventional train running simulation device is:
The train speed condition is input to the on-vehicle device under test using the oscillator, the control condition of the ground equipment is input at an appropriate position, and how the on-vehicle device responds to the input information. The operation state of the on-vehicle device is checked by monitoring whether a proper operation is performed.

[0004]

However, in the conventional simulation apparatus, the input operation of the train speed condition, the input of the control condition from the ground equipment, and the like are manually input each time. Also, changes in train speed and the like were manually set. For this reason, it was difficult to realize a train running state similar to the actual train running state. For this reason, the train must be actually run to check the operation of the onboard device.

The present invention has been made in view of the above circumstances, and various information for controlling the running state of a train can be automatically generated or changed only by presetting the conditions for controlling the running of the train. Easy operation similar to state
It is an object of the present invention to provide a train running simulation device that can easily check the operation of the device under test .

[0006]

For this reason, as shown in FIG. 1, a train running simulation apparatus according to the present invention is capable of arbitrarily setting a running speed condition of a train based on the set running speed condition. Speed information creating means for creating information, and ground control information creating means for creating speed control information from the ground based on the set control conditions and for outputting to the device under test When the driving operation information generation means for generating driving operation information based on the arbitrarily set set the cab operating conditions operating conditions, each creating information of said speed information forming means and the driving operation information creating means The speed information is created based on the

You .

As shown by a broken line in FIG. 1, data reading means for reading the operating state data of the device under test recorded when the train is actually run into the train running simulation apparatus, and the data reading means. Based on the operation state data read in, the speed information creating means, ground control information creation means and driving operation information creation means to output the same information as when actually running the train, the same as when the operation state data recording It is preferable to add a control means capable of reproducing the train running state.

[0008]

According to this configuration, the train control conditions from the ground equipment such as the train speed conditions such as acceleration, deceleration and speed, the signal display, the track circuit conditions and the like, and the operating conditions of the cab are set in advance. Since information for predetermined train traveling control can be automatically generated and changed based on these set conditions, it is possible to realize a simulated traveling state of a train similar to the actual train traveling state.

Thus, it is possible to confirm the same operating state of the device under test as when the train is running, without actually running the train. According to the second aspect of the present invention, the train running state at the time of data recording can be reproduced based on the recorded data of the operating state of the device under test when the train is actually run. The operation of the on-board device can be confirmed by reproducing the train running state.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows the configuration of an embodiment of the train running simulation device according to the present invention. In FIG. 2, a simulator 1 as a train running simulation device of the present embodiment
Is a keyboard 2 for arbitrarily inputting and setting a traveling speed condition of a train, for example, an acceleration condition, a deceleration condition or a speed, and an operating condition of a cab, for example, a notch operation, a brake handle operation, and a train traveling direction operation. A cab input unit 3 as driving operation information creating means for arbitrarily inputting and creating driving operation information based on the set operating conditions, and control conditions of ground equipment, for example, presenting conditions of a traffic light and track circuit conditions. A card reader 4 for reading the condition data from the IC card in which the speed control information is read from the ground equipment based on the control conditions read via the card reader 4, and a train from the simulator control unit 6 to be described later. A ground equipment condition generator 5 for outputting the speed control information to the device under test 8 in accordance with position information and the like in the same manner as when an actual train is running; A built-in computer, creates train speed information based on the setting conditions from the keyboard 2, outputs a speed signal similar to the output form of the speed generator to the device under test 8, The speed information is variably set based on the driving operation information from the device 3 and the brake operation information as the output information from the device under test 8,
And a disk drive device 7 for reading information recorded on a floppy disk or the like, for example. The simulator control unit 6 generates the running state of the simulated train based on the train running conditions set artificially from the keyboard 2, the cab input unit 3, the ground equipment condition generating unit 5, and the like. The cab input unit 3 and the ground equipment condition generation unit 5 are controlled based on the data read by the device 7 so that the information creation and the information output can be controlled. For this reason, the simulator 1 of the present embodiment records the operation state of the on-board device when the train actually runs, for example, on a floppy disk, and reads the operation record from the floppy disk to record the operation record. It is possible to reproduce the same train running state as at the time.

Here, the keyboard 2 and the simulator control section 6 constitute speed information creating means, and the card reader 4
The ground control information generating means is composed of the ground equipment condition generating section 5, the simulator control section 6 corresponds to the speed information changing section and the control section, and the disk drive device 7 corresponds to the data reading section. Next, the simulator of the present embodiment
The operation when 1 is applied to the operation check of the ATS-SP type on-board device of the ATS device will be described.

Here, the ATS-SP type on-board device prepares a stop pattern on the on-board device side in the case of a stop signal indication based on the frequency variation condition of the grounding element applied to the existing ATS-S type. By comparing the current train speed with the stop pattern and automatically operating the brake when the actual train speed exceeds the speed indicated by the stop pattern, the starting accident of the signal is prevented.

When a previously stored simulator program of the simulator 1 is started, a speed signal (a speed pulse similar to that of a speed generator) is input to the device under test 8 based on the set conditions, and the running state of the train is simulated. Occurs.
Simultaneously, the simulator control unit 6 outputs a signal indicating the running position of the train to the ground equipment condition generation unit 5. The ground equipment condition generator 5 outputs train control information from the ground equipment to the device under test 8 at an appropriate train position based on the line section data read from the IC card.

For example, when the stop (R) indication is generated, a stop pattern is created on the device under test 8 side, and if the speed signal from the simulator control section 6 exceeds the stop pattern, the brake output from the device under test 8 is output. The speed signal output to the simulator control unit 6 to the device under test 8 is attenuated at a predetermined deceleration. If notch operation information is input via the driver's cab input unit 3, the speed signal is increased at a predetermined acceleration, and if brake operation information is input, the speed signal is attenuated at a predetermined deceleration.

As described above, if various train running conditions are set in the simulator 1 in advance, when the program of the simulator 1 starts, the train running according to the set conditions and the train control information from the ground equipment are automatically performed. Generation can be realized. Therefore, even if the train is not actually run, the same state as when the train is run can be reproduced to check the operation state of the device under test. In addition, since the setting conditions can be set arbitrarily, the operation of the device under test 8 can be confirmed assuming various running states.

Further, in the simulator 1 of the present embodiment, as shown in the flowchart of FIG. 3, an actual train running state can be reproduced. First, the operating state at that time of the on-board equipment for actually running the train and performing the test is recorded on a floppy disk. On the floppy disk, input / output states of the on-board equipment such as speed input information, train control information from ground equipment, output information from on-board equipment, and the like are recorded in accordance with the traveling distance of the train.

The actual train running state is reproduced from the data recorded on the floppy disk. That is, in step 1 (indicated by S1 in the drawing and the same hereinafter), the simulator control unit 6 reads the recorded data in the floppy disk via the disk drive device 7. In steps 2-4,
Set speed information, train control information from the ground equipment, and driving operation information, respectively.

In step 5, a speed signal is output to the device under test 8 based on the setting information in steps 2 to 4, and the ground equipment condition generator 5 transmits the train at the same train position as when the train actually runs. Generates control information and reproduces the same train running state as recorded on the floppy disk. As a result, it is possible to confirm what kind of operation the onboard device actually performed when the train was actually run, so that a more accurate operation check can be performed as compared with the case where only operation check by simulation is performed. It becomes possible. Therefore, it is possible to improve the efficiency of the development of the on-board equipment of the ATS or ATC system which controls the train according to the control information from the ground equipment, and furthermore, the cause when a trouble occurs in the already installed system. The efficiency of the investigation can be improved.

[0019]

As described above, according to the present invention, when a simulated traveling train is generated, the generation of train control information from the ground equipment, the train speed, the traveling direction, etc. are automatically varied according to the set conditions. A state similar to the actual train running state can be realized. Therefore, the operation of the on-board device can be checked under the same conditions as when the train is running without actually running the train. In addition, since the train running state at the time of data recording can be reproduced based on the recorded data of the operating state of the device under test when the train is actually run, the actual train running state is reproduced and the on-board device is reproduced. Operation can be confirmed.

Accordingly, the efficiency of the development of on-board equipment such as the ATS system and the ATC system for controlling the train in accordance with the information from the ground equipment and the efficiency of investigating the cause when a trouble occurs in the existing system of this type are improved. be able to.
