Description

Operation event recording device for automatic train protection system

The present invention relates to a recording device, and more particularly to an operating event recording device for an automatic train protection system.

Railway tracks are built on various terrains to allow trains to travel to various locations. To ensure the safety of trains, automatic train protection (ATP) systems are installed on trains and tracks. They are also called train overspeed protection systems or automatic train protection systems. They are systems that automatically brake when a train exceeds a specified speed.

Please refer to FIG. 1 . A general automatic train protection system includes an automatic speed protection device 91, a sensing device 92 connected to the automatic speed protection device 91, a speed detection device 93 connected to the automatic speed protection device 91, an operation event recording device 94 connected to the automatic speed protection device 91, and a control display device 95 connected to the automatic speed protection device 91. The sensing device 92 has a plurality of responders 921 disposed on the rail and a receiver 922 disposed on the train, so that the automatic speed protection device 91 can obtain the track position. The automatic speed protection device 91 stores the There are multiple speed limits corresponding to different track positions. The speed detection device 93 can transmit the wheel speed to the automatic speed protection device 91, so that the automatic speed protection device 91 can monitor the running speed of the train, and actively reduce the train speed when the train speed exceeds the speed limit to avoid the train derailment. The control display device 95 can display the operation data of the automatic speed protection device 91 and provide the driver with operation. The operation event recording device 94 can record the data of the automatic speed protection device 91 to provide a reference for maintenance personnel when checking and repairing, and can provide data for analysis when an accident occurs.

Although the prior art discloses an operation event recording device that can record the data of the vehicle speed automatic protection device, it still has the following disadvantages in actual use:

1. Unstable power supply: The power of an electrified train is obtained by using a pantograph installed on the top of the train to contact a high-voltage wire to obtain power for running. However, the power obtained by contact is not stable. Especially when the train is moving, the pantograph and the power transmission line often have poor contact, resulting in a power outage. In addition, the high-voltage power system on the track supplies power in a zoned state. When the pantograph of the train moves to the middle of different power supply areas, power outages often occur due to discontinuous power supply. If the power supply of the operating event recording device is unstable, the stored data will be incomplete and the life of the electronic components will be shortened.

2. Inability to fully record train status: The general automatic train protection system's operation event recording device will only record basic data, such as train speed, response time, train position, automatic braking events, etc. However, many data unrelated to the speed are not recorded by the operation event recording device, resulting in incomplete stored data, which hinders subsequent data analysis.

3. Inability to back up data in real time: General operation event recording devices only have the function of storing data. In addition to plugging in an external data storage device or connecting to an external computer, the data stored in the operation event recording device can be backed up. Therefore, the current automatic train protection system cannot achieve the function of real-time data backup.

Therefore, how to provide a stable power supply so that the operation event recording device can stably store data, store train information more completely, and back up the stored data in real time is a goal that relevant technical personnel need to work hard on.

Another technical means of the present invention is that the main unit mentioned above further includes a power input port disposed on the housing and connected to the storage unit, and the power supply module is connected to the power input port to transmit power to the storage unit.

Another technical means of the present invention is that the operation event recording device of the automatic train protection system further includes a vehicle speed display unit, the automatic train protection system further includes a speed detection device for detecting the wheel speed, the main unit further includes a speed input port connected to the speed detection device, and a speed output port connected to the vehicle speed display module, the data control module has a speed/vehicle speed calculation component, the data control module is connected to the speed input port and the speed output port respectively, the speed/vehicle speed calculation component calculates the wheel speed into the driving speed, the data control module stores the driving speed in the data storage module, the vehicle speed display unit includes a vehicle speed display module, and the data control module outputs the driving speed to the vehicle speed display module.

The beneficial effect of the present invention is that, since the power supply module directly draws power from the power storage module to provide the storage unit, the power supply module is not directly connected to the train power supply system, thereby blocking noise or surges in the train power to avoid damaging the electronic components in the storage unit. In addition, the data control module directly obtains the wheel speed of the speed detection device, which not only enables the driving speed seen by the driver to be consistent with the data storage unit, but also The data stored in the module is the same. When the automatic speed protection device fails or the control display device cannot display the screen, the driver can also obtain the running speed of the train through the speed display module. In addition, the wireless transmission module can instantly back up the data in the data storage module to the train protection radio system in an area where wireless signals can be transmitted, which can avoid the loss of the data stored in the data storage module.

From the above description, it can be seen that the operation event recording device 94 of the automatic train protection system of the present invention does have the following effects:

1. It can provide stable power: Since the storage module 72 can first store the power provided by the train, the power supply module 71 can directly draw the power in the storage module 72 and provide it to the storage unit 4. Therefore, the power supply module 71 is not directly connected to the train's power supply system.

2. Ability to record train conditions in all directions: When the train is running on the track, the operation event recording device 94 can not only record the operation data of the automatic speed protection device 91 and the control display device 95, but also connect with the door control device 11 of the train, the camera device 12 of the train, the speed detection device 93, and the speed display module 51 to obtain more train operation events and record them.

3. Real-time backup function: The train protection radio system 14 can distribute wireless network signals in the area of the level crossing or other track locations. When the train enters the wireless network signal, the wireless transmission module 61 can connect to the wireless network and transmit data with the security protection server or the server of the train control center, so that the data control module 41 can back up the data in the data storage module 42 in real time to the cloud, so that the latest multiple operation event data can be stored in the cloud, and further, the data can be found in the cloud after the operation event recording device 94 is damaged, thereby achieving the concept of establishing a black box in the cloud.

In summary, the power supply module 71 directly draws power from the power storage module 72 to provide power to the storage unit 4. Therefore, the power supply module 71 is not directly connected to the train's power supply system, thereby blocking noise or surges in the train's power to avoid damaging the electronic components in the storage unit 4. The data control module 41 does not obtain the running speed from the vehicle speed automatic protection device 91, but directly obtains the wheel speed of the speed detection device 93 for calculation. Not only can the running speed seen by the driver be the same as the data stored in the data storage module 42, but also when the vehicle speed automatic protection device 91 fails or the control display device 95 cannot display the picture, the driver can still obtain the running speed of the train through the vehicle speed display module 51. The wireless transmission module 61 can connect to the network when entering the wireless transmission area, so that the data control module 41 can instantly back up the data in the data storage module 42 to the cloud. When the operation event recording device 94 is damaged, the multiple operation event data can be found in the cloud to achieve the concept of establishing a black box in the cloud, so the purpose of the present invention can be achieved.

However, the above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of implementation of the present invention. In other words, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are still within the scope of the present invention patent.
