The present invention relates to a train stop automatic control system that allows trains entering the station yard to stop in place, in particular, by detecting the position of the train entering the platform to visually indicate the distance from the stop position Continuously and automatically control the operation of the train braking system to calculate the braking deceleration or braking acceleration required to stop the train at the exact stop from the position and speed of the train. By doing so, it is possible to prevent stop position defects and unsafe braking and to eliminate accidents and inconvenience caused by this.

In addition, by transmitting and receiving train operation information through a communication means, the train operation information is transmitted to a station that does not have an appropriate train operation control device installed or to a station where the train operation control device does not operate normally. For controlling the operation of the device, Korea Patent Application No. 10-2006-0024556, "Principle of Automatic Position Stopping Automatic Control System and Its Control Method" (hereinafter referred to as "Prevention Application 1") Patent Application No. 10-2006-0033411 relates to an improved design of the "train on-position stop guidance system" (hereinafter referred to as the application design 2).

The non-safe braking refers to braking in which a passenger's tipping phenomenon occurs due to braking. For example, even though the actual distance to the exact stop is 3m, when the train braking system recognizes this as 5m and brakes, the train stops at the exact stop and the driver stops the brake force. It must be raised so that the train stops at the stop at the 3m position. At this time, braking occurs beyond the range of comfort due to inertia, and thus the passenger is oriented in the forward direction, which is referred to as unsafe braking. Same as below.

In the present specification, the train control system (TRAIN CONTROL SYSTEM: TCS), ATS (AUTOMATIC TRAIN STOP SYSTEM: train automatic stop device), ATP (AUTOMATIC TRAIN PROTECTOR: train automatic protection device), ATC (AUTOMATIC TRAIN CONTROL SYSTEM) : General Train Control Device), ATO (AUTOMATIC TRAIN OPERATING SYSTEM) such as the conventional devices for controlling the operation of the train, and the on-board device of the train operation control device, the train operation control device Refers to a device mounted on the train, and the ground device of the train control device refers to a device installed on the ground of the train control device.

In addition, the train control system refers to a variety of conventional devices that are installed on the ground to control train operation and exchange information. For example, it refers to the ground equipment, screen door system, and ground signal equipment of the train control system.

As is well known, trains are a mass transportation means that high safety, reliability and accuracy should be secured first.ATS, ATP, ATC, ATO, etc. Many train operation control devices have been developed and used, and continuous research and development have been conducted to improve safety, accuracy and operation efficiency and to provide a convenient driving environment.

The safety, reliability and accuracy of these trains are required throughout the entire process from the departure of the train to the stop of the train.In particular, the safety and accuracy of stopping at the platform where the passengers get on and off are further enhanced in terms of improved comfort and passenger protection. It is emphasized.

In fact, unsafe braking caused by inexperienced driving or inaccurate control of train control system may cause passenger injuries, and inaccurate stops may cause confusion of platform to reduce driving efficiency and cause accidents. Of course, there was a problem that the exchange of train operation information in the station premises is not smooth.

As technology has advanced and passenger traffic on trains has increased, a screen door system has been developed to enhance the safety of passengers in the platform.

This screen door system is a very useful facility to improve passenger safety, air conditioning efficiency and air quality in the station by installing a fixed door and a movable door at the end of the platform to block the platform and the track part.

However, such a screen door system completely blocks the platform and the track part with the screen door in between, so that accurate stops are required for smooth getting on and off of passengers.

This will be described as follows.

As is well known, in the case of a domestic subway, the error limit of the stop position is limited to 35cm left and right, and accordingly, the screen door is manufactured and installed accordingly, so the driver needs to stop the train accurately within the error range of 35cm.

FIG. 2 is a system diagram showing an example of a conventional train brake system (TBS), and as shown in the drawing, a braking signal distributor 3 connected to a braking control unit 1 and a daytime controller 2; A brake electronic control unit (MICROPROCESSOR CONTROLLED ELECTRONIC CONTROL UNIT: ECU) 4 connected to the brake signal distributor 3 via a brake line 6 and a brake device 5 connected to the brake electronic control unit 4. )

Such a conventional train braking system (TBS) is a braking control unit (1) that receives a braking command from a train operation control device (TCS), such as ATC or ATO, or a braking controller (2) operated by a crew. When the command is generated, it is encoded by the brake signal divider 3 and transmitted to the brake electronic control unit 4 installed in each vehicle through the brake line 6, and the brake electronic control unit 4 The braking of the train is performed by controlling the operation of the braking device 5 according to the transmitted command.

This will be described in detail as follows.

When the train enters the station yard, in the case of ATO autonomous driving, the distance between the current position of the train and the exact stop (7), the number of trains and the average load are calculated, and the train is moved to the exact stop (7). After calculating the braking force (braking deceleration amount) required to stop, it is input to the braking signal distributor 3 through the braking control unit 1.

The braking signal divider 3 generally comprises an encoder, and encodes a braking signal input from the ATO and outputs the braking signal to the braking line 6.

As illustrated in FIG. 3, the braking line 6 includes three signal lines a, b, and c for commercial braking and one signal line d for secure braking. Using (a, b, c), a seven-step braking command from B1 to B7 is transmitted to the braking electronic control unit 4 mounted on each vehicle (hereinafter referred to as "step control method"). &Quot; step control signal ").

Then, the braking electronic control unit 4 receives the command transmitted through the braking line 6 to control the operation of the braking device 5 to perform the commanded braking operation.

In the case of manual operation, the driver operates the daytime controller 2 to encode the signal generated by the braking controller 1 and the braking signal distributor 3 to the braking electronic control unit 4 through the braking line 6. By transmitting, it is the same as the above-mentioned operation except that the initial braking signal generator is the driver.

For reference, in the case of the train braking system adopting the step braking method, there is also a system in which the step braking signal is directly applied to the braking line 6 by the braking control unit 1 without the braking signal distributor 3.

However, the conventional train braking system as described above has a problem in that the braking force calculated in the case of automatic driving does not coincide with the actual braking force, and thus it is not easy to stop in the right position. Due to the need to rely on a highly skilled person, there was a problem that comfortable and smooth stop is not easy.

This will be described in detail as follows.

As described above, in the case of automatic driving, the braking force (braking deceleration amount) is calculated in consideration of the current speed of the train, the distance to the stop position 7 of the train, the time of arrival, the number of trained vehicles and the average load.

However, the load of the train varies depending on the number of passengers in addition to the load of the train itself, and furthermore, there is a problem that structural errors occur in the braking force calculation because the passengers are frequently getting on and off.

In addition, in calculating the distance from the exact stop 7, there is a problem that an accurate stop is difficult due to an error between the actual distance and the distance recognized by the train due to wear of the wheel.

Therefore, the braking control step, which was conventionally 7 steps (B1 to B7), is further subdivided through PWM (PULSE WIDTH MODULATION) control as shown in FIG. Although a system for inducing accurate exact position stops has been developed and commercialized (hereinafter referred to as a "PWM control method" and this signal is referred to as a "PWM signal"), there is a problem that the conventional problems as described above remain.

That is, in the case of the conventional train braking system (TBS), the structural error of the various conditions is included in the braking force (braking deceleration amount) calculation because the braking force is generated by calculating various operating conditions in the train which is the braking subject. There was a problem that it is difficult to stop the exact position.

In addition, the error occurrence requirements such as the change in the wheel diameter due to the change of the load or wear of the train, which is constantly changing, are difficult to solve the problem, which inevitably makes it difficult to stop the correct position accurately. This causes unsafe braking and inaccurate stopping of the train, deteriorating the quality of the train, causing confusion in the platform, and in some cases, causing a fatal accident.

Figure 5 is a system diagram showing the configuration of the original application 1 "train stop position automatic control system and its control method" to solve the above problems, as shown in the figure, the speed of the train entering the platform And a ground signal controller 10 for calculating the deceleration and the amount of braking deceleration necessary for the stop of the right position and transmitting the deceleration to the train; A vehicle signal controller 20 installed in a train and controlling a braking operation of the train by receiving a signal transmitted from the ground signal controller 10 and applying the signal to a train braking system (TBS); And, after detecting the deceleration from the position and the speed of the train entering the platform via the ground signal control unit 10 calculates the amount of braking deceleration necessary for the stop of the right position and transmits it to the vehicle signal control unit 20 And controlling the braking operation of the train braking system (TBS) in the on-vehicle signal control unit 20 so that the train stops at the correct position.

The first application of the applicant 1, the position of the train entering the platform through the train detection means (11a to 11e) of the train detection unit 11 of the ground signal control unit 10, and through the speed detection unit 12 When the speed of the train is detected and the ground control unit 14 calculates the braking deceleration amount of the train for the exact position and transmits the signal to the vehicle signal control unit 20 through the signal transmission unit 13, the vehicle signal control unit ( Received by the signal receiving unit 21 of the 20) through the ground signal control unit 22 and the braking signal output unit 23 to apply the braking deceleration amount for the stop position to the braking control unit 1, the braking signal By repeatedly performing the operation of controlling the operation of the braking apparatus 5 through the distributor 3, the braking line 6 and the braking electronic control unit 4, the train is stopped at the correct position.

In the figure, reference numeral 7 denotes an exact stop point, 8 denotes a management office, and 9 denotes a communication network.

Figure 6 is a system diagram showing the configuration of the original application 2 "train stop position guidance guidance system and control method thereof", as shown in the drawing, is installed along the track and to one or more train detection means (S1 ~ Sn) A train detection unit 31 configured to detect a train entering the platform; A controller (34) connected to the train detector (31) for calculating a position of the train from a distance between the signal input from the train detector (31) and a stop position (7) of right position; A display unit 36 connected to the control unit 34 and configured as a time display unit to display the position of the train according to a signal applied from the control unit 34; A power supply unit 32 for supplying power to each unit; And deriving the stop of the train by detecting the position of the train entering the platform and displaying the position of the train with respect to the stop of the stop position (7). Induction system.

Such an applicant's original design 2, by continuously detecting the position of the train entering the platform through the train detection unit 31 to determine whether or not the distance from the stop position (7), the exact position stop point (7) whether the stop and the distance is visually displayed through the display unit 36 to guide the stop position by stopping the stop position bad and unsafe braking to prevent accidents and inconvenience caused by this I would have to.

However, the applicant's prior application 1 as described above transmits a braking deceleration rate for detecting the position of the train at the ground signal controller 10 and stopping at the stop position 7 to the on-board signal controller 20 to brake the train. Although the train was stopped in position by controlling the operation of the system TBS, the signal flow consists of unidirectional communication consisting of the on-vehicle signal control unit 20 installed on the vehicle from the ground signal control unit 10 installed on the ground. As it is about the braking deceleration of the train and the location and speed of the train, there was a problem in that train operation information generated in the car, such as a train door open signal, could not be transmitted to a ground device installed on the ground.

In addition, the applicant's prior application 2 visually displayed the train position from the stop position 7 through the display unit 36 to guide the stop position of the train, but the driver is displayed on the display unit 36. Even though the signal was recognized, there was a problem in that an accurate stop could not be performed if the train braking control was not properly performed.

An object of the present invention is to solve the conventional problems as described above, in particular, to accurately detect the position of the train entering the platform to indicate the distance from the stop position to the exact position, the exact position stop point from the position and speed of the train By controlling the braking operation of the train braking system by detecting the braking deceleration or braking acceleration amount to stop on the train, the train stops at the right position. System ".

In addition, by using the communication means for transmitting the location of the train to the ground signal equipment installed in the platform, the ground operation device of the train operation control device, or the screen door system or management room to configure the signal duplex system as well as appropriate Train operation information is transmitted to a station that does not have a train operation control device installed or to a station that does not operate normally to control the operation of a device in a station such as a screen door system.

Meanwhile, when the train signal is transmitted by performing the boarding point signal control step (S200), the train signal control step (S100) is performed to control the operation of the train braking system to stop the train at the fixed position stop point (7). Let's go.

This will be described in detail as follows.

As illustrated in FIG. 12, the train controller 140 performs a position signal receiving step S110 to transmit a signal for a train position transmitted from the boarding point signal controller 200 through the on-board communication controller 150. Will receive.

Braking amount calculation step (S150) for detecting the degree (or braking acceleration amount) and the calculated braking amount (braking acceleration amount, or braking acceleration amount) to control the operation of the train braking system (TBS) to stop the train in position The stop position control step (S160) for stopping at the point (7) is performed sequentially.

This will be described as follows.

As is well known, the train entering the platform is subjected to braking to stop at the stop position 7 by the control of the train operation control device.

Therefore, when the braking deceleration amount (or acceleration amount) of the current train is detected and the train is controlled by the braking amount, the operation of the train braking system (TBS) is controlled by determining whether the train can stop at the right position. The train stops at the fixed stop 7.

That is, the remaining distance from the speed of the train detected by the station signal control unit 200 and the speed detected by the speed detector 120 to the stop position 7 and the required amount of braking (braking deceleration amount, or Calculating a braking acceleration amount, and controlling a braking of the train by applying a signal to the train braking system (TBS) to calculate a current braking amount to increase or decrease the braking amount. S200) and train signal control step (S100) is to continue to perform until the train stops to stop the train at the stop position (7).

In other words, whenever the trains are detected by the photosensors D1 to D17, the above process is repeatedly performed to continuously control the braking of the train to stop the train at the stop position 7.

As described above, the first embodiment particularly detects the position of the train entering the platform and displays the position in front of the track and the cab to easily guide the stop of the position, and also provides a signal for the train position. By transmitting to the train to calculate the amount of braking deceleration or braking acceleration required to stop the train at the stop position 7, the train by continuously controlling the operation of the train braking system (TBS) with the calculated value It has the effect of stopping at the right position.

However, in Example 1, the speed of the train is detected through the speed detector 15, but the technical idea of the present invention is not limited thereto.

That is, as shown in Figure 8, it will be noted that the speed of the train can be detected using a separate speed detection sensor 121.

In addition, in the first embodiment, the signal applied to the train braking system has been described as an example of inputting a signal to increase or decrease the current braking force. However, the technical spirit of the present invention is not limited thereto.

That is, the braking operation of the train braking system can be controlled by applying a step signal or a PWM signal indicating the amount of braking required to stop the train at the stop in position, or by applying the signal directly to the braking line 6. To reveal.

In addition, in Example 1, the deceleration or acceleration of the train is calculated by the train control unit, but the technical spirit of the present invention is not limited thereto.

That is, as shown in FIG. 8, it is apparent that the separate acceleration / deceleration detection unit 170 using the acceleration sensor can be mounted and detected.

In addition, in the first embodiment, 17 train detection means (optical spectrometers) constituting the train position detection unit are used and the detection distance is limited to 200 cm, but the technical idea of the present invention is not limited thereto.

That is, more or fewer train detection means or longer or shorter distances can be detected as needed.

Hereinafter, the operation and the effect of the second embodiment configured as described above will be described.

Detailed descriptions of matters overlapping with those of the first embodiment will be omitted.

First, when the train enters the platform, the platform control unit 240, as shown in Figure 15, performs the ground signal control step (S400) to enter the location of the train entering the platform through the train location detection unit 230 The train position transmission step (S410) for transmitting to the train signal control unit 100 is performed.

This will be described in detail as follows.

As described above, each of the RFID tags T11 to T27 constituting the train position detection unit 230 stores its own installation position data.

Therefore, when the train enters the platform and reaches a communication range with any one of the RFID tags T11 to T27, the RFID reader of the on-board communication control unit 150 of the train signal control unit 100 151 configures a communication circuit with the corresponding RFID tag to detect the position data stored in the RFID tag constituting the communication circuit.

Then, the train control unit 140 recognizes the location stored in the RFID tag constituting the communication circuit as the location where the train exists.

That is, by forming a non-contact communication circuit between the RFID tags (T11 ~ T27) and the RFID reader 151 to transmit the position of the train, each of the RFID tags (T11 ~ T27) trains the position of the train by contactless communication The function of transmitting to the signal controller 100 is further performed.

In addition, the RFID tags T11 to T27 having transmitted the position data through the communication with the RFID reader 151 transmit a signal indicating this to the boarding point control unit 240 to apply the train position to the boarding point control unit 240. .

After transmitting the position of the train by performing the train position transmission step (S410), the distance from the detected position of the train to the exact position stop point 7 is calculated to indicate the position of the train through the position display unit 250.

For example, when the train signal control unit 100 transmits a door control signal (open, close, re-opening and closing signal) for controlling the screen door of the screen door system through the RFID tag 152, it is a long distance contactless communication circuit. Detected by the RFID reader of the terrestrial communication control unit 210 constituting the control unit is applied to the screen door system (PSD) of the train control system 40 through the signal output unit 260 to control the door opening and closing of the screen door.

The same applies to other train signals (train running information).

In addition, after performing the train position display step (S340), through the on-board train operation information detection unit 110 detects the train operation information generated in the train and transmits to the platform signal control unit 200 to detect and transmit Step S350 is performed.

That is, the train operation information generated from the onboard device (TCS / T) of the train operation control device is detected and transmitted to the RFID tag forming the terrestrial communication control unit 210 through the RFID tag 152 of the onboard communication control unit 150. The platform control unit 240 is then applied to the train control system 40 through the signal output unit 260.

For example, when the door control signal (door open, close, re-opening and closing signal) is generated in the ATO on-vehicle device forming the train driving control device (TCS), it is detected through the on-vehicle train information detection unit 110 and the RFID tag ( 152) and the platform controller 240 via the RFID reader 210, and the platform controller 240 transmits the signal to the screen door system PSD of the train control system 40 through the signal output unit 260. This operation can be performed.

Then, the screen door system 240 performs the corresponding operation, and transmits the operation state to the train control unit 140 through the RFID tags T11 to T27 and the RFID reader 151 to process according to the transmitted signal. Can be done.
