[ When the obstacle detection apparatus 100 detects a disconnection of the obstacle detection network 200, the train which intends to enter the line 50 or 60 stops according to the stop signal of the signal. Then, the trainee of the train confirms whether or not the line 50, 60 is obstructed and presses the release button device 300 when it is judged that there is no obstacle to the train operation.

12, the receiving module unit 113 includes a matching transformer 11301, a filter unit 11302, an output adjusting unit 11303, a first amplifying unit 11304, a first rectifying unit 11305, A switching unit 11306, a comparison control unit 11307, an input measuring terminal unit 11308, a second amplifying unit 11309, a relay driving control unit 11310, an interface unit 11311, a display notification unit 11312, A first constant voltage section 11314, a fuse section 11315, and a second constant voltage section 11316. [

The matching transformer unit 11301 receives the detection frequency signal from the tuning unit 120 (more specifically, the reception tuning unit 122). The matching transformer unit 11301 can isolate the detection frequency signal received from the tuning unit 120 from the external environment. The matching transformer unit 11301 can adjust the input ratio of the detection frequency signal received from the tuning unit 120 to a necessary input ratio (for example, 1: 1 or 1: 0.5, etc.) to the receiving module unit 113 .

At this time, the band-pass filter may be implemented to pass a frequency corresponding to a frequency band (for example, 824 Hz or 879 Hz) of the detection frequency signal output from the transmission module unit 112.

The output control unit 11303 can adjust the output level of the detection frequency signal output from the filter unit 11302 to a level required by the obstacle detection apparatus 100 (more specifically, the reception module unit 113).

In the exemplary embodiment, the first rectification section 11305 provides the DC voltage value of the rectified detection frequency signal to the comparison control section 11307 when the DC voltage of the rectified detection frequency signal is equal to or greater than a preset reference value.

The frequency selection switch unit 11306 provides the detection frequency value set in the reception module unit 113 to the comparison control unit 11307. For example, when the transmission module unit 112 outputs the detection frequency for one line to the detection network 200, the frequency selection switch unit 11306 changes the detection frequency for one line (for example, 824 Hz) 11307). Alternatively, when the transmission module unit 112 outputs the detection frequency for two lines to the detection network 200, the frequency selection switch unit 11306 outputs the detection frequency for two lines (for example, 879 Hz) to the comparison control unit 11307, .

The relay drive control section 11310 can control the driving of the first obstacle relay section 131 according to the DC voltage level of the rectified detection frequency signal. For example, the relay drive control section 11310 can turn on the first obstacle relay section 131 when the DC voltage level of the rectified detection frequency signal is equal to or higher than a predetermined voltage level. On the other hand, the relay drive control unit 11310 can turn off the first obstacle relay unit 131 when the DC voltage level of the rectified detection frequency signal is lower than a preset voltage level.
