First, the vehicle PSD control device (CPCS) 1 is a device installed in a train, and is responsible for the interface between the ground PSD control device (WPCS) 2 and the train interface with the ground PSD device (3). This device is a PSD device and interface core device. It recognizes the exact position stop by the detection signal from the position stop sensor 5 and collects the door state, driving mode, and door mode in the train to generate the commands necessary for PSD control. And, via the FSK antenna 6 and the FSK loop 7, the PSD control command is transmitted to the terrestrial PSD controller (WPCS) 2.

Examples of specific control commands include operation matching between the train entrance door and the PSD according to the driving mode (unmanned, automatic / manual), operation matching between the train door and the PSD according to the door mode, and a start for preventing automatic starting of the train in the event of a PSD failure. Button control, crew warning message transmission to prevent manual departure of the train in the event of PSD failure, PSD malfunction prevention through stop position recognition, PSD and train door operation matching using ATC door release input.

In particular, the onboard PSD controller (CPCS) 1 is a terrestrial PSD controller 2 that modulates the FSK modulation method, outputs the FSK modulated data, and modulates the FSK modulated data when the FSK modulated data is received. Do it.

Here, the frequency shift keying (FSK) modulation method is called a frequency shift modulation method, in which the frequency of the carrier is varied according to the values of 0 and 1 of the digital signal, where 0 is a high frequency and 1 is a low frequency. It transmits data by assigning it, and its frequency changes corresponding to 0 and 1, but its amplitude is always constant.

That is, the FSK modulation method determines two carrier frequencies of a certain amplitude, and sends the allocated frequency of the two frequencies to the receiver as the data is changed to 0 and 1, and the receiver receives the original frequency of 0 and 1, which is promised. It is a modulation method that reduces the state.

In the present invention, by using a low frequency band of 79 kHz ± 1.2 kHz as a carrier PSD for a vehicle PSD controller (CPCS) 1 and a 65 kHz ± 1.2 kHz band as a carrier for a terrestrial PSD controller (WPCS) transmission, Communication between the onboard PSD controller (CPCS) and the ground PSD controller (WPCS) is possible only within ± 2m from the stop position, so interference from other communication devices and communication errors caused by other terrestrial PSD controllers (WPCS) Can be prevented.

Next, the ground PSD controller (WPCS) 2 is a device corresponding to the ground PSD controller, and is responsible for the interface with the CPCS for the interface with the train.

Specifically, data is exchanged by serial communication with the PSD controller of the PSD device 3. PSD information (PSD closed / open state) is collected from the PSD controller, and outputted to the next-order PSD controller 1 through the FSK loop 7 and the FSK antenna 6. On the contrary, the PSD open / close command is received from the onboard PSD control device 1 via the FSK loop 7 and the FSK antenna 6 after receiving the PSD control command according to the train stop situation or the driving mode of the train. Is generated and output to the PSD controller of the PSD device 3.

In addition, the ground PSD controller (WPCS) 2 also modulates the vehicle PSD controller 1 by the FSK modulation method and outputs the FSK-modulated data, similar to the vehicle PSD controller 1, and outputs the vehicle PSD. When data is received from the control device 1, the FSK modulated data is demodulated.

The platform screen door (PSD) device 3 has a PSD controller, which monitors the opening and closing state of the door in real time, and outputs it to the ground PSD control device (WPCS) 2. The door opening and closing is controlled in accordance with the opening and closing command of the door from the ground PSD control device (WPCS) 2.
