Description

Train automatic braking system and method thereof

The invention relates to an automatic train braking system, in particular to a system and method for detecting roadside dangerous conditions and controlling automatic train braking.

Automatic Train Protection (ATP) is a train auxiliary driving system that can automatically brake when the train exceeds the specified speed, and the automatic train protection system will be equipped with ground devices to receive light signals next to the track Light information of the device. At present, the light signal device installed beside the track is equipped with a green light and a red light. The red light state prohibits the train from passing forward, and the train can only pass forward when the green light state is in the green light state. The driving of the train must control the train according to the light signal, and the automatic train protection system It is the monitoring system of the train control system, which can assist the driver to control the train and prevent the train from continuing to move forward when the red light of the light signal device is on.

The automatic train protection system (ATP) has been installed on the active trains of Taiwan Railways, and ground devices are installed on each road section. When the train passes the ground sensor (transponder, balise), the speed limit information is transmitted, and the speed limit is reached to remind the driver. Protect the train function, and record parameters such as train speed, operating level, and fault information in the recording unit (RU) of the automatic train protection system (ATP).

Refer to Fig. 1, be the Republic of China Patent No. I579163, illustrate a kind of on-board device 1 of train control system, the on-board device antenna 11 of this train control system, in order to receive the ATC signal of train control information; On-board wireless machine 12, use To receive the CBTC signal of train control information; the ATC control unit 13 can control the train based on the train control information contained in the ATC signal; the CBTC control unit 14 can control the train based on the train control information contained in the CBTC signal; and The selection part 15 is used to select the ATC control part 13 or the CBTC control part 14; the speed detector 16 can detect the vehicle speed. The ATC control unit 13 can grasp the position and speed of the train based on the position information and speed information, and the stop zone information (and speed limit information) contained in the ATC signal can perform braking control of the train based on the generated speed comparison pattern, to control the speed of the train.

Although the prior art discloses a speed control technology of rail trains, it still has the following disadvantages during actual use:

1. Unable to stop the train in a critical situation:

Tracks will be set on many terrains to support the running of trains. Some terrains may have dangerous situations. For example, railways set on the side of hillsides are prone to dangerous situations of falling rocks, and some control areas such as caves It is easy to encounter biological intrusion, and even the track next to the road will have vehicle intrusion. The current automatic train protection system cannot protect the train from automatically executing the braking procedure in the above dangerous situations.

2. The signal transmission is easily disturbed by noise:

Due to the heavy weight of the train, it takes a certain distance for the train to stop at high speed. Different types of trains have different braking capabilities. The four-car EMU brakes at 80 km/h. The required distance to stop 100 meters, but a train with 10 carriages and a heavy load requires a distance of more than 800 meters from braking at 80 km/h to a stop. Therefore, it is necessary to inform the train that the braking point is more than 1 km to 5 km away from the dangerous area. To reserve enough distance between trains, where, due to the very long distance of information transmission, the sensor (transponder) that outputs radio waves is easily interfered by noise and outputs wrong signals.

3. Not under the control of the Action Control Center:

At present, the traffic control center of the train is connected by radio voice communication. The train in motion cannot understand the status of the running track, and can only drive according to the light signal on the track (green light is feasible, red light is stop). When the center receives a dangerous situation, it cannot change the light signal immediately. It must be notified layer by layer to the control system of the light signal to change the light signal to red. In addition, it will cost a lot of money to use the radio to notify the driving of the train. Due to the contact time, the operation control center cannot directly control the train to carry out the braking procedure.

Therefore, how to detect the safety status of the surrounding environment of the track, and immediately notify the train to brake when a dangerous situation occurs, and ensure that the train can correctly receive the command of emergency braking, is an urgent goal for relevant technical personnel.

In addition, a group of wires connecting the passage switch module 324 and the passage control module 313 will be added between the roadside state integration device 31 and the wireless transmission device 32, so that the passage control module 313 The generated power is transmitted to the channel switch module 324. For example, the channel switch module 324 needs to receive a current of more than 0.1A, and the coil of the channel switch module 324 can activate the switching element, wherein the channel control module 313 drives the channel switch module 324 in a constant current driving mode to determine that the channel switch module 324 can be activated.

In the data analysis step 904, the data analysis module 315 uses the judgment data to analyze whether the critical data stored in the data recording module 314 is correct, and when the critical data is correct, it indicates that a dangerous situation is occurring in the warning area. When the channel opening step 905 is executed, when the critical information is incorrect, it means that the state of the warning area is safe, and the system standby step 901 is re-executed.

In the channel opening step 905, the state integration module 311 controls the channel control module 313 to output power to control the coil magnetic switch element of the channel switch module 324, so as to control the data transmission channel 322 in the channel conduction state.
