The present invention relates to a control system and method of a train, and more particularly, to an insulation section operation control system of a train for controlling a train when entering an insulation section of a train and a control method thereof.

Typically, trains are powered by external lines through wires and pantographs. In this way, power supplied through wires may be converted from direct current to alternating current, alternating current to direct current, or different types of alternating current due to environmental differences in power supply and differences in management companies.

In this case, in order to prevent the train vehicle and its components from being damaged by the sudden change in the power supply as described above, an insulation section in which power supply is interrupted from the live wire between the sections where the power supply is converted (hereinafter referred to as insulation Section is provided on the train route.

Since the train proceeding to the insulation section as described above does not receive power from the outside, the power control device including the MCB (Main Circuit Braker) is driven by the driver's operation or automatic control, and the train is driven from the internal battery. It is operated with the power supplied for the minimum operation.

Typically, the recognition of the insulation section as described above is accomplished by the detection of grounders separately installed on the track, such as ATS grounders.

However, in the conventional train control system as described above, the insulated section is incorrectly generated because the distinction between the existing ATS ground mounted on the track and the ATS ground for detecting the insulation section is not made clearly by the cause such as external noise. By recognition, there is a problem that the operation control of the insulation section is not made accurately.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an insulation section operation control system and a control method thereof capable of accurately recognizing the insulation section so that the operation of the insulation section of the train is accurately performed. have.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, an insulation section operation control system 100 of a train according to a preferred embodiment of the present invention includes a detector 120, a speed calculator 130, a setting unit 140, and a power control device. 150, an alarm output unit 160, a timer 170, a memory unit 180, and a controller 110.

The detector 120 is for detecting the ground section 10 for detecting the insulation section among the grounders installed on the track. The track is divided into a plurality of sections, and each ground is provided with a grounder to indicate the section limit speed in the section to control the operation of the train.

These grounders have a frequency response due to electromagnetic interaction with the ground equipment installed in the train vehicle during the train's progress, and the section limit speed indicated by the grounders is detected. This is done by the determination of the response frequency generated during the interaction between the vehicle and the onboard device.

The grounder and the on-vehicle device in the present embodiment represents the ATS ground and the on-vehicle device, it will be appreciated by those skilled in the art that the ground and on-vehicle device by another system is included in the scope of the present invention if the functions and actions are the same. It can be.

As described above, the detection unit 120 generates a specific frequency oscillation phenomenon by interaction with the grounding section 10 for detecting the insulation section among the plurality of ATS grounders installed in the line, and then moves to the insulation section. Judge entry.

When the detection unit 120 detects the insulation section detecting grounder 10 by the detection unit 120, the control unit 110 uses the electric power supplied from the battery installed inside the train vehicle from the time when the train enters the insulation section to the departure. The power control device 150 is controlled so that the train can operate.

In addition, the alarm output unit 160 is driven to notify the control station and the driver of the train to enter the insulation section of the train. The alarm output unit 160 outputs sound information or image information to notify the entry of the insulation section as described above.

The speed calculation unit 130 is for calculating a running speed of a train, which is a reference for determining whether the detection of the ground section 10 for insulation section detection is performed correctly. This is to prevent the frequency response phenomenon caused by the noise during the train operation to be mistaken that the ground section 10 for detecting the insulation section is detected, and when the train operating speed is high, there is a lot of noise and the train operating speed is high. In the case of a slow, it is for detecting the ground section 10 for detecting the insulation section in consideration of the low noise generation.

The operation speed calculation of these trains is calculated by using the train speed signal output from the ATS onboard device in the case of a train to which the ATS system is applied, and separately installed in the train in the case of a train that is not applied to the ATS system. The train speed is calculated using a train speed signal output from a speed detector (not shown).

The setting unit 140 is for setting a plurality of conditions including the above-described method for calculating the driving speed of the train, and includes first to fourth setting units 141, 143, 145, and 147. Considering the case where the train systems are different, each module can be applied to different train systems. A plurality of conditions including a method of calculating the speed of a train will be described in order below.

The first setting unit 141 of the setting unit 140 sets the above-mentioned train speed calculation method, and in the case of a train to which the ATS system is applied, sets the train speed of the train from the speed signal output from the onboard device or In case of trains without ATS system, it is set to calculate the running speed of the train from the speed signal output from the separately installed speed detector, or set so that it is not necessary to detect the running speed of the train. The non-detection of the running speed of the train determines that the train enters the insulation section by the controller 110 when certain conditions are satisfied regardless of the running speed of the train. In addition, when calculating the driving speed of the train by using the signal output from the onboard device, it is possible to set whether the ATS system is a system that outputs 8 pulses per revolution or 16 pulses output system so that the speed calculation unit ( 130, it is preferable to allow the operating speed of the train to be calculated.

In addition, the second setting unit 143 of the setting unit 140 sets the frequency response reference time T _s2 of the train detecting grounder 10. As described above, the noise is generated according to the running speed of the train to prevent a mistake in the occurrence of frequency oscillation and entering the insulation section even when the insulation section is not. In other words, when the train speed is high, the noise is more likely to occur, so the frequency response reference time (T _s2 ) is increased to reduce the error of the insulation section caused by the noise. Therefore, set the frequency response reference time (T _s2 ) less.

That is, the control unit 110 does not determine that a specific response frequency is detected when the train is running and immediately enters the insulation section, and when the response time lasts more than a predetermined time, that is, the response reference time T _s2 (T _s1 ) or more, insulation It is judged to enter the section and prevents a mistake by noise. Here, the reaction reference time T _s1 will be described later. In addition, by setting the response reference time (T _s2 ) in accordance with the running speed of the train to effectively enter the insulation section.

The third setting unit 145 of the setting unit 140 is to set the information of the wheel of the train, because the diameter of the wheel and the number of pulses output per one revolution is different for each vehicle of the train, so that it can be set selectively The module is applied to various other vehicles so that the speed calculation unit 130 calculates the running speed of the train according to the corresponding train.

In addition, the fourth setting unit 147 of the setting unit 140 sets the reference time T _c for controlling the power control device 150 and the alarm output unit 160 of the train when the train enters the insulation section. As the driving time of the power control device is different for each train, the control reference time T _c is set in consideration of this.

The timer 170 counts the response reference time T s ₁ (T s ₂ ) and the control reference time T _c of the above-described insulation section entry detection grounder 10 to the controller 110 for each time. To print information.

On the other hand, the memory unit 180 is pre-stored the frequency response reference time (T _s1 ) to match according to the running speed of the train. That is, when the operating speed of the train is fast, the response reference time T _s1 is long, and when the driving speed is slow, the response reference time T _s1 is shortened and stored. This is operated independently from the reaction reference time T _s2 set by the second setting unit 143. This will be described later.

By the insulation section operation control system 100 of the train configured as described above, various conditions can be applied to other train systems as one module.

Hereinafter, a control method of an insulation section driving control system according to a preferred embodiment of the present invention will be described with reference to FIG. 2.

First, the driving speed calculation method of the train is set in the first setting unit 141 of the setting unit 140 (S100), and the third setting unit 145 for the number of output pulses per revolution of the wheel and the wheel diameter The information is set (S105), and the memory reference unit 180 stores the detection reference time of the ground section 10 for insulation section detection, that is, the response reference time T _s1 , in advance so as to match the driving speed of the train. S110).

In addition, in step S115, the control reference time T _c at which the alarm output unit 160 and the power control device 150 are controlled is set.

Subsequently, in step S120 it is determined whether or not the method for calculating the train speed set in step S100 is a system to which ATS is applied, that is, a method for calculating the train speed using the speed information output from the on-vehicle device of the train. In the case of using the speed information of the train output from the vehicle on-board speed calculation unit 130 calculates the running speed of the train (S125).

Subsequently, when the train operates, it is determined whether the ground section 10 for detecting the insulation section is detected, that is, whether a specific frequency is activated (S130), and the controller 110 detects the ground person 10. The driving speed of the train is determined, and the response reference time T _{s1 previously} stored in the memory unit 180 matching the driving speed is read to determine whether the actual frequency of response is greater than the response reference time T _s1 ( S135).

At this time, if the actual frequency response time is longer than the response reference time (T _s1 ), the controller 110 determines to enter the insulation section (S140), the alarm output unit 160 and the power control device 150, The train operation is controlled in the insulation section by driving during the control reference time T _c set in step S120 (S155).

On the other hand, if the actual frequency response time is less than the response reference time T _s1 in step S135, it is determined that the noise is due to determine that the train has not entered the insulation section, and returns to step S130 to determine whether the grounder 10 is detected. Continue to judge.

On the other hand, it is determined in step S100 whether the train operating speed is calculated by using the speed information output from a separate speed detector that is not applied to the ATS system. Determining whether the method for calculating the speed is set using the, and if it is positive, the detection reference time of the ground 10, that is, the response reference time (T _s2 ) is set in the second setting unit 143 (S170).

Thereafter, in step S130, it is determined whether or not a specific frequency is shaken by the grounding section 10 for insulation section detection, that is, whether the grounder 10 is detected, and the controller 110 determines that the response time of the actual frequency corresponds to the response reference time ( T _s2 ) is determined to be abnormal (S135), and if abnormal, it is determined that the train enters the insulation section (S140), and alarms for the control reference time T _c set by the fourth setting unit 147 in step S115. By driving the output unit 160 or the power control device 150 to control the train to run in the insulating section (S155).

As described above, when the method using the train speed information output from the onboard apparatus is set in step S105, noise is generated based on the response reference time T _s1 matched to the traveling speed previously stored in the memory unit 180. A method of determining whether or not a motion is detected and using train speed information output from the speed detection unit, that is, a train based on the response reference time T _s2 set by the second setting unit 143 in the case of a train to which the ATS system is not applied. Determine if it is the phenomenon of reaction.

On the other hand, if it is determined in step S160 whether the speed is detected by the speed detector and is negative, in order to take into consideration the effects of noise, the ground 10 detection time is followed by the operating speed of the train, and thus the operating speed is not determined. When the responsive reference time which is set regardless of the (T _s3) than copper response to determining that the train enters the isolated interval. That is, it is determined to enter the insulation section when the actual response time is not less than the response reference time T _s3 which is set regardless of the operating speed of the train without following the operation speed of the train and setting the response reference time. Since the control method is the same as described above will be omitted.

According to the present invention described above, it is possible to more accurately determine the entry of the insulation section of the train by eliminating the uncertainty of the detection of the grounders due to the noise according to the running speed of the train, so that the train control in the general section / insulation section is more accurate. It can be done accurately.

In addition, the speed calculation method of the vehicle, the response time, the operation period of the insulation section can be set in various ways through the setting unit, and thus, the effect of using the insulation section operation control system as one module in general for various trains is generated.

In addition, since the alarm for notifying the entry into the insulation section is output for a sufficient time for the driver to recognize when entering the insulation section of the train, there is also an effect to prevent the erroneous operation of the driver when entering the insulation section.
