The operation flow chart shown.

`` Opening the screen door ''

First, when the train enters the platform 1, the front and rear train check sensor unit 140 detects the train entry (S110). At this time, the front and rear train confirmation sensor unit 140 is formed with a specific stop area that can be confirmed by combining the normal train.

In addition, by combining the signals collected from the front and rear train confirmation sensor unit 140, the door opening and closing confirmation sensor unit 170 and the RF receiver 160 in the integrated control unit 240 or a normal train or passing train or freight train Determine whether (S120). At this time, if it is recognized as a passing train or a freight train that is not a normal train, the comprehensive control unit 240 resets (S121) and returns to step S110 to proceed with the subsequent process.

On the other hand, when it is determined that the normal train stops, the general control unit 240 grasps the signal sensed by the front and rear train check sensor unit 140 (S130), and determines whether the train stops within the allowable range, that is, stops at the correct position. (S140).

Thus, when the train stops in the correct position, the integrated control unit 240 lights the "good" of the front and rear stop position confirmation indicators 180 to let the crew know whether the train is in the correct position (S150). . In this case, if the train does not stop at the correct position, the integrated control unit 240 lights the "excess" or "under" among the front and rear stop position check indicators 180 to allow the crew to stop the train. The vehicle is guided to stop at the correct position (S141), and then the process returns to step S130 to determine whether the train stops at the correct position again.

The crew checks the front and rear stop position check indicator 180 to operate the open button (or lever) to open the door of the train (S160).

Then, at the same time, an RF signal indicating the door opening is transmitted from the RF transmitter 150, and the comprehensive control unit 240 checks whether the RF signal indicating the door opening is received through the RF receiver 160 and receives the signal (S170). In operation S180, the control door 230 outputs a control signal so that the screen door 110 and the safety scaffold 120 are opened. On the other hand, the integrated control unit 240 checks whether the train door is opened through the train door open detection signal output from the door open / close confirmation sensor unit 170 when the RF signal is not received, and opens the train door (S171). The control unit 230 outputs a control signal so that the screen door 110 and the safety scaffold 120 are opened. In addition, if the opening of the train door is not detected, the comprehensive control unit 240 generates a warning sound through the warning device 220 (S172), and switches to the manual mode so that the crew or passenger can open the train door (S173). The screen door 110 and the safety scaffold 120 are operated manually.

Thus, when the screen door 110 and the safety scaffold 120 are opened, the individual control unit 230 controls the indicators installed on the top of the warning device 220 and the screen door 110 to control the opening of the screen door 110. Notify the crew (S190).

Output a signal (S200).

In addition, the integrated control unit 240 stores the operation state of the screen door 110 and the safety scaffold 120 in the form of data (S210). On the other hand, this data is transmitted as necessary so that it can be received from the outside (command system).

`` Close the screen door ''

When all the passengers get on and off, the crew operates the close button (or lever) to close the door of the train, and at the same time, an RF signal indicating that the door is closed by the RF transmitter 150 is transmitted (S300).

Then, the comprehensive control unit 240 checks the reception of the RF signal indicating that the door is closed through the RF receiver 160 (S310), the screen door 110 and the safety footrest 120 to the individual control unit 230 ) And outputs a control signal to the closing operation (S320). On the other hand, the integrated control unit 240, if the RF signal is not received through the closing signal of the train door output from the door opening and closing confirmation sensor unit 170 is confirmed that the door is closed (S311), the screen to the individual control unit 230 The control signal is output so that the door 110 and the safety board 120 are closed. In addition, when the closing of the train door is not detected, the total control unit 240 generates a warning sound through the warning device 220 (S312), so that the screen door 110 and the safety footrest 120 can be closed in the crew or the station room. Mode switching is performed manually (S313), and the screen door 110 and the safety board 120 are operated manually.

On the other hand, when the screen door 110 and the safety footrest 120 is closed, the individual control unit 230 controls the indicators installed on the top of the warning device 220 and the screen door 110 to close the screen door 110. Notify the crew (S330).

At the same time, the integrated control unit 240 monitors the presence or absence of sensing signals output from the obstacle sensor 200 and the touch sensor 210 from the individual control unit 230 to detect the residual obstacle (S340). At this time, when the obstacle detection signal is sensed, the comprehensive control unit 240 opens the screen door 110 and the safety scaffold 120 (S341), and sends out a warning sound through the warning device 220 (S342), again. The presence or absence of the sensing signal output from the individual control unit 230 is monitored.

When the screen door 110 and the safety board 120 are closed, the integrated control unit 240 displays a control signal such that the closing of the screen door 110 is displayed at each operation panel (self-inside, station room, platform, and individual control unit). Outputs (S350).

In addition, the comprehensive control unit 240 stores the operation state of the screen door 110 and the safety scaffold 120 in the form of data (S360). On the other hand, this data is transmitted as necessary so that it can be received from the outside (command system).

Then, the integrated control unit 240 lights the operation completion indicator 190 to instruct the crew to start the train (S370).

Therefore, it is possible to eliminate the malfunction by operating the safety scaffolding and the screen door by determining whether the train stops correctly and whether the door is opened or closed through the communication with the train and the sensors installed in the platform. It can be found in the offices of labor, the general office, and the general command room, and the data stored can be quickly responded to safety accidents.
