Description

Simulator of Confirmation and interlock for Platform Screen Door and Stop Position, and Method of Motion Proccessing The Same}

The present invention relates to a fixed position stop and a platform screen door (hereinafter, referred to as a "PSD") interlocking check simulator (Simulator) and a method of operating the same. The present invention relates to a position stop and a PSD interworking simulator and an operation method thereof capable of confirming an abnormality of an on-vehicle signal device by implementing driving conditions under the same conditions.

In order to ensure safe and accurate operation of trains, the onboard ATO / ATP system performs automatic train control and protection, automatic train operation, and information transfer between onboard and ground, and its importance is increasing.

However, checks to ensure safety and reliability of onboard signaling devices necessarily require signal data from terrestrial signaling equipment. Therefore, it is not possible to easily check whether there is an abnormality of the on-vehicle signal device in the vehicle base inspection hall or at any place where the electric vehicle is to be inspected.

In order to solve this problem, the test methods proposed in the related art have been recently complicated by using a method of simply inputting each signal necessary for the test of a vehicle signaling device and checking an output signal thereof, or by constructing a simulation driving scenario. In order to satisfy the input conditions of the signal control devices, and to perform the inspection of the on-vehicle signal devices, a method of generating and inputting arbitrary ground signals and on-vehicle signals is taken.

However, these methods do not meet the importance of the interlocking test of each part of the onboard signaling device and the various other electric vehicle installations controlled by the devices, and the ground signal data and operation of the actual operating train operating section. By using arbitrary data based on a simulation driving scenario instead of data as an input signal of an electric vehicle signal device, there is a problem in that a driving situation and a driving environment under the same conditions as those of an actual operating train cannot be realized.

In addition, in order to perform the operation test of the intelligent train control (ATC) to realize the movement control of the train, the protection of the train, and the operation of the train, the control is based on the stop position and the recommended speed following control. A new inspection method and the presentation of inspection items are required.

In addition, for the safety of passengers, platform screen doors are installed in all platforms, and the operation of the screen doors is controlled in the train information transmitted to ground equipment after the train stops at each station. As a result of the order, a test for checking the abnormality of the data included in the train information is required, including real-time transmission of train information and screen door control commands.

Designed. In addition, by acquiring the Odometer signal of the train while the train is operating the Automatic Train Operation Device (ATO) at the recommended speed and synchronizing with the ground data, It is possible to implement the operating situation.

Receives the propulsion / braking command to control the propulsion system and the braking system in TCMS and generates speed signal based on this. After applying the environmental variables for each test condition and situation to the speed signal, it synchronizes with the ground data. It is possible to perform the exact stop and recommended speed following control test.

In order to check the status of the interlocking operation between each part of the onboard signaling device and various other electric vehicle facilities under the control of the devices, the portable TWC loop is configured to receive the status information of the onboard ATO / ATP device. By designing loop and TWC demodulation circuit, it can be configured to receive / analyze train information (TWC Telegram) of train in real time. The output status of PSD control command can be checked when handling doors.

A large part of the unusual situation that occurs during the operation of the current train is caused by the failure or malfunction of the onboard signaling device and the PSD. It is expected to minimize the occurrence of failures and maximize the operational efficiency of onboard signaling devices.

In addition, it is possible to inspect and maintain the on-vehicle signal facility only by the actual operation of the electric vehicle, but by using this signal simulator, it is possible to implement an operating situation under the same conditions as the actual operation of the electric vehicle without the actual operation of the electric vehicle.
