The present invention relates to a train automatic stop device (AUTOMATIC TRAIN STOPPER: hereinafter referred to as ATS) and control method for controlling the operation of the following train by detecting the occupation of the track of the preceding train, in particular, a plurality of along the track After installing the wireless communication device, by controlling the operation of the following train by receiving the track occupancy status and operation information of the preceding train through the wireless communication device, the installation of the ground apparatus is unnecessary, easy to maintain, Safe and high transport density to enable efficient operation.

Here, the preceding train refers to a train being operated immediately in front of the current train, and the following train refers to a current train being operated immediately after the preceding train. Same as below.

As is well known, the ATS is a device for controlling the operation of a following train by detecting a track occupancy state of a preceding train, which is composed of a condenser (C) and a coil (L) as illustrated in FIGS. 1 and 2. A grounder 11 constituting the resonant circuit; Relays (RL ₁ , RL ₂ ,,, RL _n-1 , RL _n ) and capacitors (C ₁ , C ₂ ,,,, C _n- ) turned on / off by a predetermined control signal ₁ , C _n , and connected in parallel to a plurality of capacitors C of the terrestrial 11 to change the resonant frequency by varying the capacitance of the terrestrial 11 by a predetermined control signal. A ground magnetic relay 12; Relays RL ₁ , RL ₂ , RL _{n-1 of the} terrestrial control relay 12 are selectively connected to the terrestrial control relay 12 to generate a predetermined relay control signal which is a speed command signal. A ground apparatus (10) composed of a signal device (13) for controlling the traffic light (14) and the like while controlling the RL _n ;

A primary box 21 in which primary coils and secondary coils are inductively coupled to a predetermined coupling degree to sense a resonance frequency of the ground wave 11 by frequency induction; It consists of an amplifying circuit section and an oscillating circuit section, and performs oscillation at a predetermined frequency (for example, 78 kHz) to feed back through the coil of the vehicle box 21, and simultaneously oscillate the frequency of the coil of the vehicle box 21. An oscillator 22 to amplify; A frequency detector (24) composed of a plurality of band pass filters (BAND PASS FILTER) and the like, connected to the oscillator 22 for detecting and outputting a frequency output from the oscillator 22; A speed detector 23 attached to the wheel side of the train to detect a traveling speed of the train; The signal input from the frequency detector 24 and the speed detector 23 is compared and judged by a predetermined method, and the predetermined speed is obtained when the actual speed of the train exceeds the speed (section limit speed) commanded by the ground apparatus 10. If the actual speed of the train does not become smaller than the limiting speed so that a predetermined time elapses after the alarm signal is generated, a predetermined braking signal is generated. Generating control section 26; An alarm device 27 connected to the control unit 26 for generating an alarm sound and a display control signal when an alarm control signal is generated in the control unit 26; A brake unit 28 connected to the control unit 26 for braking or braking the train when a braking signal is generated in the control unit; When the display control signal is generated by the control unit 26, the control unit 26 is connected to the control unit 26 to display a visual alarm, and when the recovery command is commanded by the driver, the signal is sent to the control unit 26. It is composed of a vehicle-mounted device 20 made of a display control device 25 for transmitting and displaying a predetermined signal generated by the control unit 26.

The conventional ATS calculates the running speed of the following train by calculating the track occupancy state of the preceding train, that is, the distance between the preceding train and the following train, thereby changing the resonant frequency of the grounder 11. It transmits to the car box to automatically control the speed of the train.

For example, as shown in Table 1, the ATS having five signal types (G signal, YG signal, Y signal, YY signal, and R signal) has operation characteristics as shown in FIG.

Signal type   Resonant frequency of ground Maximum speed by segment G  98 ± 3KHz Free operation below 150 km / h YG 106 ± 3KHz 105Km / h Y 114 ± 3KHz 65Km / h YY 122 ± 3KHz 25Km / h R 130 ± 3KHz Absolute stop

3 is a view showing the driving curve of the national railway ATS operating in the five signal forms, the five grounders interlocked with each other using the track section in which one grounder is installed as a unit (maximum speed limit). Speed).

That is, assuming that there is a train ahead of the ground station installation section (R signal section) on the far right, if a following train attempts to enter the ground station installation section, the train is stopped within a predetermined time (for example, 5 seconds). The "R signal" to stop is generated, and if the train is not stopped within the above 5 seconds, the train is emergency stopped through the brake 28.

In more detail, the grounder is installed at a predetermined position before entering the track section where the speed limit is limited by the grounder. For example, in the case of the ATS having a 5 manifestation signal type, the grounder is installed about 25m ahead. In case of ATS with three-note signal type, it is installed in front of about 1.2km.

Therefore, in the case of the "R signal", the "absolute stop" signal is commanded from a ground person installed 25m before the entry of the "R signal section" in which the preceding train exists, and the command of the section limit speed is 5 seconds or more. When this passes, the train will be stopped.

This is a slight difference in the control method according to each signal type (3, 4, 3), but the basic matters are the same, and the details are well known, so the detailed description thereof will be omitted.

On the other hand, when the train enters the "YY signal section", the next section in which the preceding train exists, the section limit speed (operation maximum speed) is limited to 25 km / h. If not, the train is stopped by the brakes 28.

The "Y signal section" and "YG signal section" continuous to the "YY signal section" is also limited by the maximum speed of the following train due to the above operating principle, the grounder installation section where the preceding train exists It is only necessary to enter the "G signal section" between the four installation sections from the train to free up the driving speed within the safe driving speed of the train.

That is, as shown in the driving curve ① of FIG. 3, the train operates normally at a speed limit below the allowable section in the section to be entered before entering each signal section. As described above, if the vehicle enters more than the section limit speed allowed in the section, the driver generates an alarm signal through the alarm device 27, and the driver confirms that the predetermined time (for example, 5 seconds) elapses after the alarm signal is generated. And if the speed of the train does not decelerate below the prescribed section limit speed by operating the brake 28 to forcibly stop the operation of the train to prevent accidents due to the speed of the train.

The driving curve ② shows a case in which the driving speed of the train is reduced to less than the section limit speed within 5 seconds after the alarm signal is generated, and the driving curve ③ is 5 seconds after the alarm signal is generated to operate the brake 26. This shows the operating curve when emergency braking is performed.

[Table 2] below shows the resonant frequency and the section limiting speed of the ATS having three signal types (three manifestation ATS), and FIG. 4 shows the driving curves of the ATS having the three signal types, respectively.

Signal type   Resonant frequency of ground Maximum speed by segment G  98 ± 3KHz Free operation below 150 km / h Y 114 ± 3KHz 65Km / h R 130 ± 3KHz Absolute stop

In the case of three-time ATS, "G signal" means free operation, "Y signal" means caution operation, "R signal" means stop, and its basic operation principle is the same as that of five-state ATS.

In other words, the section speed limit of the train is divided into three types to automatically control the operation of the train.

However, in the conventional ATS as described above, since the track is divided into a plurality of sections, and the section limiting speed for each section is transmitted to the on-vehicle apparatus through the ground apparatus, first, the ground apparatus (ground finger, ground control) There is a problem in that installation, maintenance, management, and repair costs of relays, signals, etc. are high, and second, there is an error in any part of the ground apparatus (such as a ground box, a ground control relay, or a signal), and thus the section speed limit is increased. If the command fails (for example, groundless Mudeung-dong state), there is a problem that a collision accident occurs. Third, there is a problem that transportation density (line efficiency) is low due to controlling the operation of the train by dividing the track into certain sections. Fourth, there is a problem in that there is no compatibility according to the control method of the train (3, 4, 5, etc.), and, fifth, a combination of trains (eg, train type) There is a problem that can not control accurately corresponding to the length of the, and sixth, the problem that can not provide information other than the section speed limit of the train, and seventh, to control the two-way direction (for example, up line, down line) There was a problem in that the ground equipment had to be installed on each track.

Hereinafter, the technical idea of the present invention "automatic train automatic stop device using a wireless communication and its control method" configured as described above will be described in detail with reference to the embodiment.

<Example>

In this embodiment, a base station is installed every 1 km along a line, a control station is installed for each of the 20 base stations to manage the 20 base stations, and the control station is collectively managed by the management station. At this time, the base station and the control station exchanges information with each other using wireless communication, and the control station and the management station to exchange information with each other through a wire (for example, an optical cable).

In this embodiment, it is assumed that mobile stations are provided at the head and tail of the train, respectively. At this time, the signal transmission between the mobile stations is to use a wire (you can also transmit a signal between the mobile stations using wireless).

In addition, in the present embodiment, the information transmitted from the base station is limited to the information on the installation position of each base station, the time of transmitting the information on the installation position, and the position information of the preceding train.

At this time, it is a matter of course that each of the base station, the mobile station and the control station is assigned an identification code. Since this is a general matter, a detailed description thereof will be omitted.

Hereinafter, the configuration of the present embodiment will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 5 and FIG. 7, the base station 110 is installed every 1 km along the line A, and the control station 120 is installed every 20 base stations 110, and the control station 120 is installed. Is connected to the management station 130 by an optical cable to configure the wireless communication system 100 according to the present embodiment. That is, a plurality of control stations 120 are installed under one management station 130, and 20 base stations 110 are installed in each control station 120.

At this time, the base station 110 (including the mobile station) is automatically corrected by the time data transmitted from the management station 130 through the control station 120 so that all base stations 110 always display the same time. . That is, the time of the base station 110 is always set to the time of the management station 130 transmitted through the control station 120.

The reason for keeping the time of the base station 110, the control station 120, the management station 130, and the mobile station 210 the same is that the distance between the base station and the mobile station is calculated based on the radio wave arrival time. This is because the location of the train is determined based on the calculated distance.

In addition, when the base station is installed, information about the installation location is input in the base station 110 to output information about the location and information about the location transmission time in units of a predetermined time.

On the other hand, as shown in Figs. 5 and 6, the mobile station 210 is provided at the head and the rear of the train, respectively (indicated only at the head in the drawing), and the mobile station 210 is connected to the microcomputer 220. Thereafter, the microcomputer 220 includes an alarm signal generator 230, a display unit 240, an operation switch unit 250, a speed detector 260, a speed controller 270, and a database unit 280. Each is connected to constitute a train control system 200 according to the present embodiment.

At this time, the time of the mobile station 210 to represent the same time as the base station 110 by the same method as the base station 110.

Hereinafter, the operation and effects of the present embodiment configured as described above will be described in detail with reference to the accompanying drawings.

First, when the apparatus according to the present embodiment operates, the base station 110 periodically outputs information on the location of the base station, information on the time at which the location is transmitted, and information on the location of the preceding train. Done.

Subsequently, when the train starts to operate, the microcomputer 220 of the train control system installed in the train receives the location of each base station 110 transmitted from three or more base stations and information on the transmission time to receive the current position of the train. And calculating the distance to the preceding train by receiving information on the position of the preceding train, and then calculating the target operating speed of the corresponding train according to the calculated distance, and performing the target speed calculating step (S10). Done.

That is, by measuring the arrival time of the signal transmitted from the base station to calculate the distance to the base station, and performing the operation of drawing a circle with a radius of the calculated distance for the three base stations, the intersection is a train (exactly the corresponding mobile station ) Will be present, and the position of the train obtained in the above process and the distance from the position of the preceding train (the position transmitted through the base station) to the preceding train can be known. Then, it is possible to calculate the running speed (target running speed) of the train in which the total distance is calculated from the distance to the preceding train.

Here, the arrival time from the base station to the mobile station is calculated by measuring information on the time transmitted together with the base station at the time of signal transmission with respect to the position of the base station and the time when the signal arrives. Multiply by the speed of light to get the distance to the base station. This is as noted.

The reason for receiving the signals for the three base stations 110 in the position calculation step is to prepare for malfunction of the base station or inoperability of the base station. In other words, the positioning on the two-dimensional plane needs to know the distance between the two base stations, but uses three base station signals for safety in calculating the position.

On the other hand, after calculating the target running speed of the train by performing the target speed calculation step (S10), the speed detector 260 detects the current speed of the train and accelerates the train according to the detected current speed, or By decelerating, the speed control step (S20) of controlling the driving speed of the train to be the target driving speed is performed.

In other words, when the actual speed of the train is faster than the target driving speed, the speed is reduced by braking, otherwise the speed is increased by acceleration.

At this time, since the speed control operation for calculating the target running speed and adjusting the actual speed of the train to the calculated value is continuously performed at a fast cycle until the end of the operation of the train, the train always maintains the optimum running speed, The ride comfort for maintaining the optimum traveling speed is also optimal.

On the other hand, after performing the speed control step (S20) to control the actual speed of the train to be the target running speed, it is detected whether the actual speed is the target running speed, the actual speed of the train so that a certain time elapses If does not reach the target running speed through the alarm signal generator 230 to perform an alarm signal generation step (S30) for generating an alarm signal indicating this.

In this case, when the actual speed and the target running speed do not coincide so that a predetermined time elapses and generate an alarm signal indicating the same, the alarm signal is generated only when the actual speed exceeds the target running speed.

In addition, in the alarm signal generation step (S20), apart from the alarm for the speed of the train, the operation state or signal transmission state of each component of the train is detected to detect each component (eg, pressure, brake, electric device, etc.). If the operation is not normal or the signal transmission state of the mobile station 210 and the base station 110 is not normal, it generates an alarm signal indicating this.

Herein, the signal transmission states of the mobile station 210 and the base station 110 are not normal, which means that the base station 110 signals received by the mobile station 210 are not at least three.

On the other hand, after performing the alarm step (S30), the microcomputer 220, the display step of displaying information (train records, train status, etc.) about the train operation on the display unit 240, and stores in the database unit 280 (S40) and the database update step (S50) is performed sequentially.

In addition, after sequentially performing the database update step (S50) to perform the location transmission step (S60) for transmitting the current position of the train to the base station (110).

Then, the current position of the train transmitted from the mobile station 210 is transmitted to the control station 120 and the management station 130 via the base station 110.

The control station 120 stores the information on the current position of the train transmitted by performing the position transmitting step (S60), and transmits the position to other control stations around the station, and provides the train to subsequent trains. In 130, the situation of the trains transmitted from all the control stations 120 is displayed to provide an overall situation display of the track operation state. In this case, when a command for a train operated by the management station 130 is to be transmitted to the base station 110 through the control station 120.

On the other hand, when the mobile station 210 is installed in the head and the rear of the train as in the present embodiment, the length of the train is calculated and displayed through the mobile station installed at the head and the mobile station installed at the rear. The location may be reconfirmed through communication between the mobile station installed at the rear and the rear.

In addition, since the base station installed on the side of the track is shared and used by both the up and down trains, there is no need to install the grounding device by separating the up and down lines as in the prior art.

That is, the identification code unique to the mobile station can be used to distinguish whether it is an uplink or a downline, or whether the operation of an uplink or a downline is possible through the mobile state of the mobile station. It can be used for both up and down line control.

For reference, it is preferable to determine whether or not through the identification code unique to the mobile station.

In addition, the information about the operation stored in the database unit 280 is used for the maintenance, history management of the train.
