4, the operation monitoring system 100 first measures the position of the electromotive vehicle or the opening and closing of the electric motor vehicle door and the landing pad security (PSD) or the position of the electric vehicle (S110)

More specifically, when the electric motor vehicle enters the landing, the entry sensor 111 and the real position sensor 113 sense the entrance and the stop position of the electric vehicle, and generate a measurement value.

When the electric motor vehicle moves on the platform, the advance sensor 112 senses the advance of the electric motor vehicle and generates a measured value.

The door detection sensor 114 and the PSD detection sensor 115 sense the opening and closing states of the doors and doors of the railway car and the pedestrian safety gate (PSD), respectively, and generate measurement values.

Then, the analysis unit 131 determines whether or not a malfunction of at least one of a train, a motor vehicle access door, and a landing gear safety (PSD) based on the measurement value received in the communication interface 120 is detected (S120)

As described above, the analyzing unit 131 may be configured such that when the train does not stop at the platform, or if the stop position deviates from a predetermined normal range, or if the PSD door and the platform safety gate (PSD) are not opened or closed, It is judged to be a malfunction.

Then, the output unit 132 generates an error signal based on the determination of the analysis unit 131 (S130)

The CCTV 160 is a device for capturing real-time images of an exit of a motor vehicle, a PSD, and a train.

Here, the CCTV 160 is preferably installed in each of the PSDs in terms of securing the visual field. However, the present invention is not limited to this, And may be spaced apart from each other along the longitudinal direction.

The image data photographed by the CCTV 160 is transmitted to the communication interface 120 in real time.

The operation unit 150 determines whether the sensor unit 110 is operated and calculates a correction value for correcting a malfunction of at least one of a train, a motor vehicle access door, and a pedestrian safety gate (PSD).

More specifically, the operation unit 150 includes a detection unit 151 and a calculation unit 152.

The detection unit 151 determines whether or not the measurement value is received in the communication interface 120.

That is, it is possible to distinguish the corresponding sensor whose measurement value has not been received through the detection unit 151, and the analysis unit 131 can judge whether the malfunction has occurred based on the image data, instead of the measurement value not received.

The calculating unit 152 calculates a correction value for correcting a malfunction of at least one of a train, a motor vehicle door, and a landing gear safety (PSD) based on the image data.

More specifically, when the measured value of the forward position sensor 113 is not received, the calculating unit 152 calculates the time required for reaching the preset normal range from the position of the train disposed on the screen in real time based on the image data The remaining distance is calculated.

That is, the calculating unit 152 calculates the remaining distance, which is a correction value for correcting the malfunction of the electric train, and the output unit 132 generates a driving signal corresponding to the correction value and outputs it to the cab monitor of the electric vehicle, .

When the measured values of the door detection sensor 114 or the PSD detection sensor 115 are not received, the calculation unit 152 calculates the difference between the measured values of the door data, And calculates a correction value corresponding to opening or closing for activating the specialist (PSD).

The output unit 132 may generate an opening / closing command signal corresponding to the correction value to operate the door opening / closing device of the railway car door or entrance / exit security door (PSD).

Therefore, the engineer or the manager can attempt to correct the malfunction before manually controlling the door of the motor vehicle or the landing pad security (PSD), thereby preventing the delay of the train due to the simple error.
