The present invention detects the failure of the railroad crossing traffic controller (alarm type, alarm light, continuous alarm, no alarm, low voltage state of the battery, breaker), and informs the station equipment to prevent the railroad crossing accident in advance. It relates to a fault detection apparatus of a controller.

In order to detect a failure of a conventional railroad crossing traffic controller, it was inconvenient to detect a failure only by going directly to a railroad crossing and operating a traffic controller one by one, and accordingly, a failure occurred in a railroad crossing traffic controller. If not detected, there was a drawback that a railway accident, which was originally intended for a railroad crossing controller, could not be prevented.

In view of the above, the present invention, when the alarm bell, alarm lamp or breaker of each railroad crossing traffic controller does not operate, continuous alarm or no alarm, or when the charge voltage of the battery is below a certain voltage, it automatically detects it and reverses it. By informing the station apparatus is invented to immediately identify which passage controller of the crossing is a failure state, described in detail by the accompanying drawings as follows.

As shown in FIG. 1, the fault detection unit 30 of the railroad crossing traffic controller detects an alarm type, an alarm lamp, a fault condition of the breaker or a continuous alarm or no alarm, or detects when the charging voltage of the battery is lower than a predetermined voltage. Applied to the transmitter 40, and accordingly, the alarm transmitter 40 generates an oscillation signal corresponding to its own crossing and stops transmitting to the receiver 11 of the station apparatus 10, thereby corresponding to the crossing where the transmission signal is stopped. The display lamps of the monitoring panel and the alarm 12 are turned on to generate an alarm sound.

The alarm type fault detection unit 31 is configured to operate the RL ₁ ) and the RL ₂ , and the power B ⁺ is applied to the _{first and} second alarm lamps L ₁ and L ₂ , which are controlled by the alarm lamp control unit 22. The fault detection unit 32 is configured to operate the relays RL ₃ and RL ₄ by detecting the normal operation of the lamps 1 and 2 detection units 32a and 32b. Arrival is counted by the time detector 33b connected to the oscillator 33a to determine whether the alarm according to the control of the relay controller 23 continues for a predetermined time, and then the amplifiers 33b, 33d and To the control of cross-selection switches (SW _1), a transistor (TR _1), the on by the relay (RL ₅₎ is to be continued from the alarm detecting unit 33, even if the train arrives at the railway crossing, the relay controller 23 operates through If the alarm does not occur according to the non-alarm monitoring unit 34a is configured to operate the relay (RL ₆ ) alarm-free detection unit 34, and the charge voltage of the battery 24 selector switch (SW) ₂ ) Monitors the 24V and 12V voltage monitors 35a and 35b and operates the relay RL ₇ when the charge voltage of the battery 24 is normal, and the charge voltage of the battery 24 is equal to or less than a predetermined voltage. In this case, the battery low voltage detection unit 35 is configured to stop driving of the relay RL ₇ . In addition, the breaker monitoring unit 36a monitors the operation state of the breaker under the control of the breaker control unit 25 and the rising angle with the breaker monitoring unit 36a to operate the relay RL ₈ when the breaker does not operate normally when the train is folded. The failure detection unit 36 is configured.

Alarm type and the failure detection unit 31, 32 of the present invention configured as described above is the first and second alarm species (B ₁ ), (B ₂ ) and the _first and second alarm lamps (L ₁ ), (L ₂ ). The first and second detection sections 31a, 31b and the back 1,2 detection sections 32a, 32b detect whether the power supply B ⁺ is normally applied, and if the relays RL ₁ and (RL _{2 are} normal) ), (RL ₃ ) and (RL ₄ ) in operation, without power supply (B ⁺ ) or with 1st and 2nd alarms (B ₁ ), (B ₂ ) and 1st and 2nd alarm lights (L ₁ ) When the power (B ⁺ ) line to be applied to (L ₂ ) is opened, the first and second detection units 31a and 31b and the first and second detection units 32a and 32b detect this and the relay thereof. The driving of (RL _1a ), (RL ₂ ), (RL ₃ ) and (RL ₄ ) is stopped. In addition, when the train approaches the railroad crossing, an alarm is generated by the control signal of the relay control unit 23. Since the control signal is continuously applied to the time detector 33b of the alarm detector 33, the control signal is applied to the time detector 33b. If the control signal is continuously applied for a predetermined time or more in accordance with the oscillation signal of the oscillation unit 33a, the high potential signal is output to the output side thereof, and this high potential signal is the amplifier 33c or the amplifier 33d. After the amplification at, the transistor TR ₁ is turned on through the time selection switch SW ₁ . Here, the time selection switch SW ₁ is a switch for selecting the time counted by the time detection unit 33b according to the disconnection or the double line section of the train line. As described above, when the transistor TR ₁ is turned on, the relay RL ₅ is operated. In addition, when the train approaches the crossing, the control signal is generated from the relay control unit 23, but if the alarm is not generated because the relay is not operated, the alarm is detected by the alarm-free monitoring unit 34a of the alarm-free detection unit 34 and relayed. When the RL ₆ is operated, the charging voltage of the battery 24 is applied to the 24V voltage monitoring unit 35a or the 12V voltage monitoring unit 35b through the selection switch SW ₂ , and when the charging voltage is higher than a predetermined voltage. The relay RL ₇ is operated, and the drive of the relay RL ₇ is stopped when its charging voltage is discharged and becomes below a predetermined voltage. The selection switch SW ₂ is used to select the 24V voltage monitoring unit 35a or the 12V voltage monitoring unit 36b according to the capacity (24V or 12V) of the storage battery 24. Then, the circuit breaker monitoring unit 36a of the circuit breaker failure detecting unit 36 monitors the internal contact operation state of the circuit breaker control unit 25 that operates the circuit breaker, and operates the relay RL ₈ when the circuit breaker operating state is not normal.

In this way, when the crossing controller 20 is normal, the relays RL ₁ , (RL ₂ ), (RL ₃ ), (RL ₄ ) of the alarm bells and warning lamps (31) and (32), and the battery low voltage detector The relay RL ₇ of 35 is operated so that its contacts RL _1a , RL _2a , RL _3a , RL _4a , RL _7a are short-circuited, and the alarm detection unit continues. The relays RL ₅ , RL ₆ , and RL ₈ of the 33 and the alarm-free detection unit 34 and the breaker fault detection unit 36 are not operated, and their contacts RL _5b , RL _6b , and ( Since RL _8b also maintains a shorted state, the power source B ⁺ is applied to the light emitting diode LED ₁ and the relay RL ₉ to light the light emitting diode LED ₁ and to drive the relay RL ₉ . Accordingly, the contact point RL _9a is short-circuited so that the power source B ⁺ is applied to the oscillator 41, so that the oscillator 41 outputs a preset oscillation signal. Since the oscillation signal is amplified by the amplifier 42 and applied to the filter 11a of the receiver 11 through the filter 43, only the signal corresponding to its frequency passes the filter 11b to the amplifier 11b. After being amplified, it is applied to the oscillator 11c, and accordingly, the oscillator 11c is operated to output an oscillation signal. Thus, voltage is induced in the secondary winding of the transformer T ₁ , and the induced voltage is applied to the rectifier circuit B ₁ . It operates the relay (RL ₁₀₎ through because paragraph his contacts (RL _10a) is applied to the power supply (B ⁺⁾ green light emitting diode (LED _2), yiettara green light-emitting diode (LED ₂₎ is lit. crossing passage controller ( 20) shows that it is normal. At this time, since the contact point RL _10b of the relay RL ₁₀ is kept open, the red light emitting diode LED ₃ is turned off and the alarm sound generator 12a is not operated. However, as described above, the alarm type failure detection unit 31 of the failure detection unit 30 and the failure detection unit 32, the continuous alarm detection unit 33, the alarm detection unit 34, the battery low voltage detection unit 35, the breaker failure detection unit If any one of the (36) is detected, the relay contacts the detection unit of the detected detector to open the fault, thereby preventing the power supply B ^{+ from} being applied to the light emitting diodes LED ₁ and the relay RL ₉ of the transmitter 40. The light emitting diode LED ₁ is turned off, and the relay RL ₉ is stopped. In this way, when the relay RL ₉ stops operating, its contact point RL _9a is opened to cut off the power source B ⁺ applied to the oscillator 41, so that the oscillator 41 stops operation, and thus the alarm receiver Since the oscillation signal applied to (11) is stopped to stop the operation of its relay RL ₁₀ , its contact RL _10a is opened, and its contact RL _10b is shorted. Therefore, the red light-emitting diode (LED ₃ ) is turned on to indicate that a failure has occurred in the crosswalk traffic controller 20, and at the same time, the alarm sound generator 12a is operated to generate an alarm sound that a failure has occurred in the crosswalk traffic controller 20. The speaker 12c is informed.

In the above description, the one crossing controller 20 detects a failure and informs the station apparatus 10. However, the failure detecting unit 30 and the alarm transmitter as described above for each crossing passage controller 20 are described. 40 is installed to output different oscillation signals for each transmitter 40, and the receiver 11 is installed in the reverse device 10 in accordance with the number of the alarm transmitters 40 to be output from each transmitter 40. It separates and receives the oscillation signal, and the contacts RL _10a and RL _10b of the relay RL ₁₀ of each alarm receiver 11 display the green and red light emitting diodes (LED ₂ ) and (LED ₃ ) for each crossing display. ) And at the same time, the common contact between the relay RL _10b of each relay RL ₁₀ to the alarm sound generator 12a through the diode D ₁ is a large number in one reverse apparatus 10. The operating state of the crosswalk traffic controller 20 can be monitored at the same time.

As described above, the present invention automatically detects a failure in the railroad crossing traffic controller and immediately informs the station apparatus so that there is no inconvenience of detecting a failure of the railroad crossing railroad traffic controller. At the same time, the railroad crossing accidents can be prevented in advance, and also a number of railroad crossing traffic controllers can be monitored at the same time at a single station, thereby reducing labor costs.
