Description

ATC / ATO onboard system for a train}

The present invention relates to an ATC / ATO onboard system of a train, and more particularly, to an ATC / ATO onboard system of a train that can be used without changing a separate complicated system mode in an ATO section and an ATC section.

Due to congestion of roads and soaring oil prices, the frequency of using trains has recently increased due to the inherent characteristics of trains such as on-time departures and arrivals and large quantities of freight.

However, due to limited tracks and time lapses due to the expansion of tracks, a method of increasing train organization while maximizing existing limited tracks, preventing train accidents, or a method for automatically operating a train has been proposed.

Among these methods, an automatic train control system (ATC) and an automatic train operation system (ATO) are proposed, and the ATC is applied from grounders such as ATC pick-up coils installed on the ground track. It is a system that receives the maximum speed signal from the onboard device and automatically decelerates when the current train speed is faster than the maximum speed signal, and the ATO is not only the acceleration / deceleration control of these trains but also the stop section such as the station at the station. Refers to a system that automatically stops or stops the door at the right place.

Comparing the ATC system and the ATO system, the development of the train control technology is developed by the ATC first and then operated in the field, and then the ATO system is developed and operated in the field.

Due to the difference in technology development and the installation time, when the ATC system is installed in one section and the ATO system is installed in one section, the control mode of the train must be switched when the section is switched from the ATC section to the ATO section. There is a problem. This conversion is provided with an ATO on-vehicle device separately from the existing ATC on-vehicle device or ATC on-vehicle device separately from the ATO on-vehicle device. As shown in the drawing, it is used only in the operating section (A) of the train and stops the train manually in the stop section (B), so there is an inefficient problem because the automatic operation by the ATO system is not possible even when the ATO vehicle is installed separately. .

In addition, installing an ATO grounder in the ATC section (FIG. 1A) or installing an ATC grounder in the ATO section (FIG. 1B) may be a solution, but it is not preferable to install the grounders in the same section in terms of cost. There is a problem that crosstalk between signals may occur.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an ATC / ATO onboard system of a train that can be operated in an ATO mode in which an ATC system is installed.

The ATC / ATO onboard system of a train according to a preferred embodiment of the present invention is an ATC / ATO onboard system that controls the operation of a train in a section in which a train stops at a station and a section in which a train operates, and is installed on the ground. ATC (Auto Train Control) ATC signal receiving unit for receiving a train speed signal from the ground; An ATO signal receiving unit for receiving a driving information signal including a train driving speed signal from an ATO (Auto Train Operation) ground mounted on the ground; A speed detecting unit detecting a driving speed of a running train; And controlling the running speed of the train by comparing the running speed signal of the speed signal received by the ATC signal receiving unit or the driving information signal of the driving information signal received by the ATO signal receiving unit by the speed detecting unit. It includes a control unit.

As a result, in the section in which the ATC system is installed (hereinafter referred to as an 'ATC section') and the section in which the ATO system is installed, it can be used together as a system without additional equipment or complicated processing.

Here, the control unit, it is preferable to control the train operation in accordance with the ATO operation information received by the ATO signal receiving section in the stop section.

As a result, even in the ATC section, it is possible to implement the ATO mode that can automatically control the stationary stop of the train or the door opening and closing.

In addition, when the train enters the stop section, TWC transmitter for transmitting the train information including the train number and the number of trains of the train to the ground command room; preferably further comprises a.

Thus, the information of the train entering the current stop section can be monitored in the remote command room.

In addition, the train information input unit; It is preferable to further include.

Thus, when the train information is changed, for example, when there is a change in the number of trains, the correct information may be corrected and inputted.

The apparatus may further include a display unit configured to display the driving speed and the driving speed information of the current train received by the ATC signal receiving unit or the ATO signal receiving unit.

Thus, the speed limit of the current section or the operating speed of the current train can be displayed to the train driver in real time.

According to the present invention, the section in which the ATC system is installed (hereinafter referred to as an 'ATC section') and the section in which the ATO system is installed can be used together as a system without additional equipment or complicated processing.

In addition, even in the ATC section it is possible to implement the ATO mode that can automatically control the stationary stop of the train, door opening and closing.

In addition, the information of the train entering the current stop section can be monitored in the remote command room.

In addition, when the train information is changed, for example, when there is a change in the number of trains, the correct information may be corrected and input.

In addition, the speed limit of the current section or the operating speed of the current train may be displayed to the train driver in real time.

Hereinafter, with reference to the accompanying drawings will be described for the automatic train control and driving system according to a preferred embodiment of the present invention.

Figure 1c is a view for explaining the ATC / ATO vehicle system of the train according to the present invention, Figure 2 is a block diagram showing an ATC / ATO vehicle system according to a preferred embodiment of the present invention.

1C and 2, the ATC / ATO vehicle system 100 of a train according to an exemplary embodiment of the present invention includes a control unit 110, an ATC receiving unit 120, an ATO receiving unit 130, and a speed detecting unit 150. It includes.

While explaining an embodiment of the present invention, the section in which the train is operated is described as a train operating section (A, A '), as shown in Figure 1c the train stop section (B, B ') will be described. In addition, the section in which the ATC system operates is described as an ATC operating section, and the section in which the ATO system is operated is described as an ATO operating section.

The ATC receiver 120 receives the driving speed signal of the train in the corresponding driving section A from the ATC grounder 125 installed in the train operating section A of the ATC operating section, and the ATC grounder 125 When the train is detected by the track circuit, the speed limit signal is transmitted to the ATC receiver 120 through the track circuit or the discontinuous transmission loop in the corresponding section. Here, since the ATC system controls to decelerate forcibly in case of violating the limited driving speed in the corresponding section during the operation of the train, the ATC grounder 125 is installed only in the driving section (A) of the train and stops (B). Is not installed.

The ATO receiving unit 130 receives the driving information from the ATO ground section 135 installed in the ATO operating section (operation section (A ') and stop section (B')) and the stop section (B) of the ATC operating section. In addition, the driving information includes information for a limited driving speed in the driving section A 'and a stop at a fixed position in the stop section B (B'). In the operating section (A ') of the train receives the speed information of the train, and in the stop section (B) (B') of the train receives information for fixing the position of the train. The ATO receiver 130 oscillates the oscillation frequency at all times and receives train operation information from the ATO ground person 135 on the ground. Here, the ATO system is to be controlled for the exact stop in the stop section (B) (B ') as well as the operating section (A) of the train, so the ATO grounder 135 operates in the ATO section (A'). And the stop section B 'as well as the stop section B of the ATC section.

Thus, as described below, the ATO mode may be implemented in the ATC driving section, such as control of the exact position of the train and door opening and closing.

The speed detector 150 detects the current driving speed of the train, and includes a speed generator 153 and a speed calculator 151. When a pulse signal corresponding to the running speed of the train is output from the speed generator 153, the speed calculating unit 151 calculates the driving speed of the train according to the wheel and outputs the same to the controller 110.

The controller 110 compares the speed limit signal received by the ATC receiver 120 or the ATO receiver 130 with the speed of the train detected by the speed detector 150 to limit the speed of the train. If it is faster, decelerate the train. In addition, the stop section is controlled to stop at the correct position of the train according to the train operation information received by the ATO receiver 130, and performs additional train operation control such as door opening and closing.

As a result, the ATC driving section and the ATO driving section can be operated in parallel without the addition of an independent device, and the ATC driving section can also perform automatic train operation (ATO).

On the other hand, according to a preferred embodiment of the present invention further includes a TWC transmitter 140, the TWC transmitter 140 is train information including the train number and the number of trains of the train using the Train to Wayside Communication (TWC) method By transmitting to the command line on the ground, you can remotely monitor information or status of current trains.

In addition, it is preferable to further include an input unit 160 through which the train information is input, so that information on the number of trains, wheels, and the like of the train is changed, so that the train information can be input so that the train can be efficiently managed. .

In addition, it is preferable to further include a display unit 170 indicating the driving speed received by the ATC receiver 120 or the ATO receiver 130 and the operating speed information of the current train, so as to visually inform the driver of this information. .

A driving method of the ATC / ATO vehicle system 100 of the train configured as described above will be described with reference to FIG. 3.

First, while the train is running, it receives a driving speed limit signal from the ground ATC grounder 125 or receives a driving information signal from the ATO grounder 135 (S110). In the received signal as described above, the signal received from the ATO ground person 135 determines whether there is a signal for stopping the exact position of the train in the stop section (B) (B ') (S120), and stops the exact position in step S120. If it is not a signal for this corresponds to the driving speed limit signal in the driving section (A) (A ') and compares the running speed and the running speed limit of the current train (S130).

As a result of the comparison in step S130, when the running speed of the train is faster than the speed limit, it is decelerated control or is accelerated control when it is slower than the speed limit (S140).

On the other hand, if the signal received in step S120 is a signal for controlling the exact position of the train received from the ATO grounder (S110) to follow the control to control the train to stop at the correct position in the stop zone (B) (B '), When the stop is confirmed, the door is controlled to be opened and closed (S150).
