The present invention relates to a CBTC onboard signaling device tester for a magnetic levitation train, and more particularly, to provide a dedicated tester capable of exhibiting all the functions for reliability verification of hardware and software of a CBTC onboard signaling device for a magnetic levitation train. It is about.

As a land public transportation, unlike cars, trains move on a defined track, so it is essential to secure safety and reliability against train collisions in consideration of the post-war trains and their relative positions. The device is the onboard signal device (ATC / ATO (AUTOMATIC TRAIN CONTROL AUTOMATIC TRAIN OPERATION)).

In the onboard signal device, it is very important to establish a mutually organic signal communication system between a train and the ground.

The signal communication system in a tracked vehicle should be a two-way communication system that monitors driving information including the position and speed information of the vehicle on the ground and transmits necessary control commands to the vehicle. The vehicle must have absolute position, speed detection device and information transmission / reception system to detect.

The wheel-type signal communication system developed so far detects the position by detecting a track circuit installed on the rail shorted by the wheel in detecting the position information of the vehicle, or detects the position from the antenna of the vehicle by installing a guide line of a certain type in the track. And the like, and the location information of the vehicle detected by the above method is transmitted and received with the ground by a wired or wireless method.

On the other hand, in the case of a new type of tracked vehicle, such as a magnetic levitation train, since a short circuit between the rail and the wheel cannot be obtained due to the non-contact method that rises on the track, the position detection by the track circuit cannot be considered. This problem can be solved by adopting a communication based trian control (CBTC) method through a LAN).

Therefore, in order to verify the reliability of the hardware and software of the magnetic levitation train CBTC onboard signal device including the above functions, a dedicated tester capable of exerting all of the corresponding functions is necessary, and when applied to an actual route, the onboard signal device is required. It is essential to check the status of faults.

However, the conventional tester is designed to perform only unit function tests using various inputs, and thus no tester has been researched or developed to inspect the CBTC onboard signal device for the magnetic levitation train as a whole.

Accordingly, the present invention is to solve all the disadvantages and problems of the prior art as described above, not only having the function of the driving device and the ground signal device of the magnetic levitation train, but also the CBTC carborne signal device for the magnetic levitation train and wired And it is an object of the present invention to provide a CBTC vehicle onboard signal tester for magnetic levitation train that can be connected to the wireless to exhibit all the functions to verify the reliability of the hardware and software of the CBTC vehicle onboard signal device.

The object of the present invention is a CBTC on-vehicle signal testing machine for testing a CBTC on-vehicle signal device for a magnetic levitation train, the discrete input and output unit for receiving a command required for the operation of the magnetic levitation train, and displays and outputs the input command ; A panel PC that receives information necessary for the inspection of the CBTC onboard signal device, displays and outputs the test process and results; A data processor connected to the discrete input / output unit and the panel PC to transmit and receive a signal, and to process information input from the discrete input / output unit and the panel PC; A wired connection device for transmitting and receiving a signal by connecting the data processor and the CBTC onboard signal device by wire; A wireless LAN device connected to the data processor to wirelessly connect the data processor and the CBTC onboard signal device to transmit and receive a signal; And a wireless LAN test unit capable of testing the wireless LAN device of the CBTC onboard signal device using the wireless LAN device.

Details of the above objects and technical configurations and the effects thereof according to the present invention will be more clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention. Like numbers refer to like elements throughout.

The CBTC onboard signaling device tester for the magnetic levitation train is designed to be suitable for the CBTC onboard signaling device for the magnetic levitation train unlike the existing tester.

That is, the conventional train speed detection method is installed on the shaft of the wheel, the pulse is input according to the speed of the wheel rotation to detect the speed of the train, but the magnetic levitation train is the microwave and the reception of the sensor mounted on the bogie The Doppler sensor detects the speed by using the frequency difference of microwaves. It uses the method of detecting the speed of the train. The conventional method of detecting the position of the train uses the method of detecting the position of the train by shorting the tracks. However, the magnetic levitation train is injured and proceeds, so the tag, which is a device for detecting the position of the train, is embedded in the track and uses the method of detecting the position of the train, and detects the position of the train. C designed to cope with phase-to-phase communication by using wireless LAN communication suitable for maglev train CBTC onboard signaling device tester for magnetic levitation train for inspecting BTC onboard signaling device is provided.

Therefore, if the CBTC onboard signal device is applied to the real line after preventing the expected problem by conducting tests to check various functions and interface with other devices from the development stage before applying the real line, the current vehicle test time can be reduced as much as possible. The CBTC onboard signal checker was designed to be able to do so.

In addition, when the CBTC vehicle signaling device is separated from the train due to a malfunction or failure after being applied to an actual route, the CBTC vehicle signaling device is designed to be connected to the CBTC vehicle signaling device tester to check whether the failure is caused by various tests.
