First, according to Figures 3 to 5, the secure device for securing a false departure train according to the present invention is installed and operated on the platform of the station where the train stops.

Such a secured safety device of a departure train is provided on the train maximum stop line 30, which is a virtual line indicating a point that should not be exceeded when the train 10 stops on the platform 20 to detect whether the train 10 has started. When a train detection signal is input from the departure detection means 110 and the departure detection means 110, trains are provided in front of the platform 20 to display the departure or absence of the train 10. Check whether the stop signal is received, and when the train stop signal is received is composed of a signal discrimination means 130 for determining that the departure of the train.

At this time, the departure detecting means 110 is installed closest to the train maximum stop line 30 in the direction of the start signal 120 from the train maximum stop line 30 passes through the train maximum stop line 30 It detects the, can be selectively used a variety of detection sensors such as proximity sensor or contact sensor.

On the other hand, when the departure detecting means 110 detects the train 10, the train detection signal is input to the signal discriminating means 130.

In this case, the signal discrimination means 130 is a first digital input card 132 for connecting with a plurality of departure detection means 110 and a second for connecting with a plurality of departure signal 120. When the train detection signal is input from the first digital input card 132 while the train stop signal is received from the digital input card 134 and the second digital input card 134, the operation is determined to be an abnormal departure of the train. Processor 136.

At this time, the start detection signal is collected from the plurality of start detection means 110 through the first digital input card 132 in a dry contact manner.

Therefore, when the departure detection signal is detected from the departure detection means 110, the first digital input card 132 transmits the state of the departure detection means 110 in charge of the platform 20 to the operation processor 136. The illegal starting state of the train 10 is checked. In this case, the starting detecting means 110 and the signal discriminating means 130 are preferably connected using a relay contact method.

Meanwhile, the signal discrimination means 130 is connected to the stop signal line of the red lamp 122 of the start signal 120. That is, when the stop signal (red lamp) of the start signal 120 is displayed or turned off, the train stop signal due to each relay contact is input to the second digital input card 134 of the signal discrimination means 130.

In this case, the signal discrimination means 130 installs a second digital input card 134 to collect information from the red lamp contact of the start signal 120 in a dry contact method, and the contact is transmitted to the interlocking device. The contact point of is used as it is to configure in the common method.

On the other hand, the signal discrimination means 130 LDTS the alarm information for notifying that the start is a false signal when the stop signal (red lamp) is input from the start signal 120 in the state that the train detection signal is input from the start detection means 110 (Local Data Transmission System) transmits to the train control system for alarm processing.

At this time, the method of transmitting the false start information to the LDTS may be transmitted by selectively applying a relay contact or various communication methods.

Hereinafter, with reference to Figure 6 describes in detail the processing of the case where the illegal departure of the train is made in the state provided with the safety securing device for the false departure train according to the present invention.

At this time, an example in which the train 10 passes by the train detecting means 110 due to a false start when the start signal 120 is a stop signal (red lamp manifestation) will be described.

When the state of the start signal 120 of the train 10 is a stop signal (red light manifestation), the train 10 starts by operating the train 10 at the driver's decision and error, and thus the train 10 stops the train maximum stop line 30. When passing through the train detection means 110 through the train detection means 110 generates a train detection signal, which is transmitted to the signal discrimination means 130.

At this time, the signal discrimination means 130 checks the state of the associated start signal 120 and generates alarm information to inform the engineer and the controller of the illegal start of the train 10 in the case of a stop signal (red lamp display) state. To the LDTS 200.

Next, the alarm information for notifying the engineer and the controller of the illegal start of the train 10 should be transmitted to both the engineer and the controller.

First, the alarm generation process for the engineer will be described.

The LDTS 200, which has received the alarm information from the signal discrimination means 130, repeatedly generates and turns off the red lamp 122 of the corresponding start signal 120 to blink the red lamp of the start signal 120. Communicate the risk to the engineer.

In this case, the interlock device 210 is used to transmit a dangerous situation to the engineer, and the interlock device 210 is divided into a method using an electronic interlocking device and a method using a relay interlocking device.

First, when the interlock device 210 is an electronic interlocking device, as shown in FIG. 7, an interface between the LDTS 200 and the electronic interlocking device 212 is performed by a communication method.

That is, the LDTS 200 that has received the alarm information about the train misdeparture from the safety securing device of the fraudulent departure train due to the fraudulent departure of the train is the communication method currently performed between the LDTS 200 and the electronic interlocking device 212 and the existing. The red lamp 122 of the start signal 120 is repeatedly transmitted to the electronic interlocking device 212 by periodically and repeatedly outputting and turning off the command of the red lamp 122 of the start signal 120 using the signal control command of the signal. By flashing) to pass to the driver driving the train 10 to recognize the danger situation due to a false start.

Such a situation is performed until the command for the corresponding start signal 120 is transmitted to the LDTS 200 in the control room 300.

At this time, since the LDTS 200 is configured to transmit the control command for the start signal 120 to the electronic interlocking device 212 only by the start signal 120 control command transmitted from the control room 300, the train starts illegally. When receiving the alarm information due to the red lamp of the start signal 120 to periodically display and turn off to program naturally.

Next, when the linkage device 210 is a relay linkage device, as shown in FIG. 8, an interface between the LDTS 200 and the relay linkage device 214 is performed by a relay contact method.

That is, the LDTS 200, which has received the alarm information about the train misstep from the safety securing device of the fraudulent departure train due to the false start of the train 10, is connected to the contact method between the LDTS 200 and the relay linkage device 214. Using the existing signal control output command, the present and turn-off commands for the red lamp 122 of the corresponding start signal 120 are periodically and repeatedly transmitted to the relay interlocking device 214 to transmit the red lamp of the corresponding start signal 120. Flashing (122) conveys a hazard to the engineer.

That is, the controller 202 of the LDTS 200 transmits a control command corresponding to the present command to the digital output module 204 when the current state of the corresponding start signal 120 is turned off. The digital output module 204 enables the output port corresponding to the output number of the corresponding start signal 120 (S1).

In this case, the relay interlocking device 214 that has received the information through the digital output module 204 displays the red lamp 122 of the corresponding start signal 120 and then displays the present state of the LDTS 200 through the contact point. The digital input module 206 transmits the present state to the control unit 202.

On the other hand, the control unit 202 transmits a control command corresponding to the light out to the digital output module 204 in order to turn off the red lamp 122 of the start signal 120 again, the digital output module 204 DISABLE the output port corresponding to the output number of the start signal 120 (S3).

In this case, the relay interlocking device 214 that has received the information through the digital output module 204 turns off the red lamp 122 of the corresponding start signal 120 and then turns off the light of the LDTS 200 through the contact point. An input module (DIGITAL INPUT MODULE) 206 is transmitted (S4), and the digital input module 206 transmits the present state to the controller 202.

The above steps (S1) to (S4) are performed repeatedly, and as in the case of the electronic interlocking device, the command for the corresponding start signal 120 is transmitted to the LDTS 200 in the control room.

In addition, since the LDTS 200 is configured to transmit the control command for the start signal 120 to the electronic interlock device only by the start signal 120 control command transmitted from the control room 300 as in the case of the electronic interlock device. When receiving the alarm information due to the illegal start of the train 10, it is natural to program the red lamp 122 of the start signal 120 to periodically display and turn off.

Next, with reference to Figures 9 and 10 will be described the alarm generation process to the control room using the train control system is provided with a safety securing device for the departure and departure train according to the present invention.

First, the safety securing apparatus 100 transmits the alarm information due to the illegal start of the train to the LDTS (200).

At this time, the LDTS 200 transmits the alarm information to the first digital service unit (DSU) 230, which is a kind of a modem for telecommunication provided in the field station signal equipment room.

The first DSU 230 transmits alarm information to the second DSU 310 of the control room 300 through the communication network 240.

Meanwhile, the second DSU 310 of the control room 300 transmits alarm information to the terminal server 320, and the terminal server 320 transmits alarm information to the control system server 340 through the internal network 330. To send.

Then, the control system server 340 flashes the red lamp of the start signal 120 to the linear information display device 350 in accordance with the alarm information to inform the controller of the dangerous situation for the illegal start of the train.

In addition, the control system server 340 flashes the red lamp of the start signal 120 on the large screen 360 according to the alarm information to inform the controller of the dangerous situation.

As a result, the controller is aware of the dangers due to train misdepartment and takes relevant safety measures, such as giving a radio notice to the engineer.

After the dangerous situation is terminated, the control information for the corresponding start signal generator 120 is generated and transmitted to the LDTS 200 of the site station signal equipment room, and accordingly, the flashing of the red lamp 122 of the corresponding start signal detector 120 is stopped. Let's go.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the scope of the present invention to be substantially equivalent to the embodiment of the present invention.
