Description

Composite railroad signal {Composite railroad signal}

The present invention relates to a complex railway signal, and specifically to a complex railway signal that combines a color light signal and a wooden signal among the permanent signals used in railways.

Departure signals attached to each track within a railway station provide conditions for departure for trains stopped on that track.

For example, if a stop signal is displayed, in principle, a train stopped on that track cannot depart.

If a signal other than stop is displayed, a train stopped on the track can depart provided that other conditions are good.

Meanwhile, in the case of a departure signal attached to a track that trains do not enter frequently, the stop signal continues to be displayed after the stopped train departs unless a special situation occurs.

According to the operating regulations of the railroad, the position of the departure signal (normally set as the default state) is specified as displaying a stop signal, and is always for safety regardless of whether a train enters the track or whether the track is used. A stop sign must be displayed.

However, in the case of a conventional color-light signal, the red lamp must be turned on continuously to indicate a stop signal, but if current is continuously supplied to a signal that is not used frequently, not only is power consumed unnecessarily, but the lifespan of the lamp is shortened. There was a problem of shortening the replacement cycle, which led to an increase in costs incurred by railway operators.

Republic of Korea Public Utility Model Publication No. 20-2017-0000437 (published on February 2, 2017)

The purpose of the present invention is to replace the stop signal displayed by the colored signal member by raising the arm by the operation of the driving member when the permanent signal displays a stop signal for a long period of time, and to provide power to the colored signal member, driving member, and control member. The purpose is to provide a complex railway signal that can be switched to a power saving state where it no longer consumes.

Also, when a train enters the track, when a situation arises where the signal must display a signal other than a stop signal due to the train operation schedule, and when the signal displays a signal other than a stop signal due to artificial signal manipulation by the controller. When a situation arises where something needs to be done, and when a worker touring the track artificially lowers the armbar for inspection and manipulates the control member to display a color-light signal member, it wakes up from the power-saving state in four situations. The purpose is to provide a complex railway signal that lowers the raised arm as a trigger and restores the operation of the color-light signal member (hiding the arm and displaying the color-light signal member). .

A complex railway signal according to the present invention for achieving the above object includes a color-light signal member having a plurality of lamps to indicate progress in color; It is installed at the rear of the color light signal member and moves up and down according to the colors of the plurality of lamps. It rises to replace a stop signal for a long time, and is provided with an arm tree that lowers except for the rising operation and is hidden behind the color light signal member. one driving member; and a control member installed on the track to control the operation of the color-light signal member and the driving member according to the entry of the train.

The driving member includes a direct current motor that receives both positive (+) and negative (-) voltages; A first gear installed on the shaft of the DC motor; A second gear meshed with the first gear, the end of the arm being installed, and an iron piece installed to move by rotation according to meshing with the first gear; First and second switches having three electrodes (contacts) whose contact points change as the iron piece moves and form interconnection and separation; and a mainspring that rotates the first gear in a direction in which the arm arm rises by tension when the DC motor malfunctions.

The driving member causes the first gear and the second gear to rotate in a direction to lower the arm when a positive (+) voltage is applied to the DC motor, and when a negative (-) voltage is applied to the DC motor, the first gear and the second gear rotate in a direction to lower the arm. The gear and the second gear rotate in the direction of raising the arm, but are provided to engage with the iron piece to fix the second gear so that the arm is not lowered by gravity when the arm is raised and the power is turned off. It further includes a first stopper and a second stopper that is provided to engage with the iron piece and fixes the second gear so that it is not shaken by wind or vibration when the arm arm is lowered and the power is cut off, and the first and second switches When the iron pieces are in contact, one of the three electrodes and one of the remaining two electrodes are opened, and at the same time, the remaining one of the two remaining electrodes is closed, respectively. When the iron piece is not in contact, the three electrodes may be opened and closed opposite to when they are in contact.

When a signal is to be displayed by the color-equipped signal member, the control member directly connects an already installed signal device and a plurality of lamps to control the display of the signal, thereby allowing current to flow so that the lamps of the color-equipped signal member operate according to the signal. It is turned on, and in measuring the display time of the signal, it forms a form including a capacitor, a variable resistor, an operational amplifier, and a plurality of resistors, and when it is confirmed that the color light signal member is displaying a stop signal for a long time, the color light signal is turned on. The path of current flowing through the member can be blocked.

A portion of the current input to display the stop signal through the color signal member is used to charge the capacitor through the variable resistor so that the voltage between the electrodes of the capacitor gradually increases according to the display time of the stop signal. , the voltage supplied from the power source of the control member is lowered through a voltage distribution effect by another variable resistor and another resistor connected in series to form a reference voltage, and the voltage by the variable resistor or resistor is transmitted through the operational amplifier. To be compared, if the voltage of the capacitor is confirmed to be higher than the reference voltage through the output of the operational amplifier, it is determined that a stop signal is displayed for a considerable period of time through the color-light signal member, and the first relay of the driving member is Alternatively, the second relay is excited to close the open contact and at the same time operate to open the closed contact, and the excited first relay or second relay is connected to the power source of the control member through one of the contacts to be closed. It can be operated to maintain an excited state by continuously receiving current from the power source until the switching operation of the driving member is completed.

The control member includes a control circuit, and the control circuit is composed of a plurality of SPST (Single Pole Single Throw) switches linked to a plurality of relays to prevent operation of the DC motor of the driving member when the arm is raised. When the negative (-) voltage supplied to the driving member returns according to the operation of the driving member that returns the negative (-) voltage, the plurality of devices open or close the SPST switch with the negative (-) voltage. By energizing the relays and opening the SPST switch, the plurality of relays that were energized are deactivated so that the driving member does not consume power and, on the contrary, wakes up from the power saving state.

When the drive member enters a power saving state, the path of the current flowing through the color light signal member can be blocked to stop the operation of the color light signal member.

The control member includes a control circuit, and the control circuit is composed of a plurality of SPST (Single Pole Single Throw) switches linked to a plurality of relays to prevent operation of the DC motor of the driving member when the arm is lowered. When the positive (+) voltage supplied to the driving member returns according to the operation of the driving member that returns the positive (+) voltage, a plurality of the plurality of devices open or close the SPST switch with the positive (+) voltage. By energizing the relays, and by opening the SPST switch, the plurality of relays that were energized are deactivated so that the driving member does not consume power, and by closing the SPST switch, the color signal member is It can be made to operate by allowing current to flow through it.

When a malfunction occurs, current is directly supplied to the plurality of relays that open or close the contacts of the SPST switch without waiting for the positive (+) or negative (-) voltage to return from the driving member, The path can be directly connected so that current flows through the signal member.

According to the configuration of the present invention described above, it is applied to a departure signal attached to a track where a train rarely enters a station or a reverse departure signal that is rarely used in the direction in which the train runs, and stops by a wooden signal, which is a mechanical signal, instead of a color light signal. By not only displaying the signal, but also restoring the color light signal to display only in situations where a train enters or a train must depart in the reverse direction, there is a low possibility that the driver will check the right track when operating on the relevant track, and the color light signal is not used as before. It is possible to drive by checking the displayed signal, which has the effect of ensuring that the driver's driving handling is no different from before.

However, since the operation of the color-light signal member is stopped while the train is not entering, the power consumed to display the stop signal for a long time can be saved, and the replacement cycle of the lamp displaying the stop signal can be extended. Since the signal that indicates a stop by raising the It also has an effect.

Above all, when infrequently used colored signal members are turned off, the departure signals on tracks where trains frequently travel within the station stand out more visually, so the engineer operating the train in that direction must check the frequently used tracks and in that direction. There is also the effect of being able to identify signals to be used more easily than before.

In addition, for infrequently used departure signals, they are activated only when absolutely necessary, so when an engineer operating a train on a rarely used track and in that direction checks the relevant departure signal, the absence of a color light signal that is displayed at a high brightness similar to that of a new one. This also has the effect of making it easier to identify the signal.

As a result, without compromising the safety of train operation, the cost and energy consumed by displaying the stop signal for a long period of time can be dramatically reduced, thereby ensuring both economic efficiency and eco-friendliness.

Hereinafter, with reference to the attached drawings, preferred implementation configurations for realizing the purpose of the present invention described above and the functional relationships according to these configurations will be described, and detailed descriptions of technical configurations that are the same or in the same category as the conventional ones will be omitted. Do this.

The present invention relates to a complex railway signal that combines a color light signal and a wooden signal among the permanent signals used in railways.

To this end, the configuration of the complex railway signal according to the present invention, as shown in Figures 1 to 4, is a color-equipped signal equipped with a plurality of lamps (301, 302, 303, 304) to indicate progress in color. A drive equipped with a member 300 and an arm 202 installed at the rear of the color signal member 300 to raise and lower according to the colors of a plurality of lamps 301, 302, 303, and 304 to indicate whether a stop signal is present. It may be composed of a member 201 and a control member 101 installed on the track to control the operation of the color signal member 300 and the driving member 201 according to the entry of the train.

As shown in FIGS. 1 and 4, the control member 101 of the present invention includes a power-saving pedal switch 102 that has an upper end that can be stepped on and forcibly enters a power-saving mode, and a power-saving pedal switch 102. Likewise, the upper part may be made in a form that can be stepped on with a foot, and may be provided with a release pedal switch 103 that forcibly wakes up from the power saving mode.

In addition, it is desirable to provide a cable 104 connecting the drive member 201, the color signal member 300, and the rail and track circuits 401a and 401b, which will be described later.

The driving member 201 of the present invention can be supplied with direct current power, as shown in FIGS. 2 to 5, and can be supplied with a positive (+) voltage or a negative (-) voltage based on ground, and the voltage By changing the direction of rotation of the built-in DC motor 501 according to the polarity of , the arm tree 202 can be raised and lowered.

A bolt fastening portion 204 is provided at the upper end of the driving member 201, so that it can be fixed to a non-moving place such as the color signal member 300 or an already installed signal pillar, and can be connected to the control member 101. Electrical connection can be made between the cables 203.

It is desirable that the arm tree 202 is made of a material with high reflectivity and excellent photoluminescence (the property of accumulating light and emitting light when it gets dark) so that it can be easily identified even in weak light or at night.

The specific detailed configuration of this drive member 201 includes a DC motor 501 that receives both positive (+) and negative (-) voltages, and a first gear installed on the axis of the DC motor 501. (502) and a second gear (503) that meshes with the first gear (502), is installed at the end of the arm (202), and rotates in accordance with meshing with the first gear (502), and the second gear (503) Equipped with an iron piece 504 installed in and three electrodes (contact points, 505a, 505b, 505c / 506a, 506b, 506c) whose contact points change depending on the position of the iron piece 504 and form mutual connection and separation. It consists of first and second switches (505, 506) and a mainspring spring (507) that rotates the first gear (502) in the upward direction of the arm neck (202) by tension when a failure of the DC motor (501) occurs. It can be done.

For example, as shown in FIGS. 3 and 4, with the driving member 201 installed on the color signal member 300, the first lamp 301, the second lamp 302, the third lamp 303, and the The four lamps 304 are lamps that must be provided to display color-equipped signals, and can be displayed in the following order: 'Stop', 'Warning', 'Caution', 'Slow down', and 'Proceed'.

In addition, the line that uses all of the above-mentioned five signals is called the '5-signal section', and only 'stop', 'caution', 'caution', and 'proceed' are used, or only 'stop', 'caution', and 'slow down' are used. A track that only uses 'and' 'progress' is called a '4-string section'.

In addition, the section using only 'Stop', 'Caution', and 'Proceed' is generally called a '3-presentation section', and the section using only 'Stop' and 'Proceed' is generally called a '2-presentation section'.

At this time, the 'stop' signal may be displayed as red through the second lamp 302, and in this case, the train cannot, in principle, pass the signal.

In addition, the 'boundary' signal can be displayed as two yellow colors through the first lamp 301 and the fourth lamp 304, and in this case, the train can depart and pass the corresponding signal.

However, as there is a high possibility that the next signal is 'Stop', passing at a speed of approximately 25 km/h or less is basically permitted.

In addition, the 'caution' signal can be displayed as a single yellow color through the first lamp 301, in which case the train can depart and pass the corresponding signal.

However, in the '5 current section', as there is a high possibility that the signal for the next section is 'boundary', passing at a speed of approximately 65 km/h or less is basically allowed.

In the '4-hour zone and below', passing at a speed of approximately 45 km/h or less is permitted as the next signal is likely to be 'Warning' or 'Stop'.

In addition, the 'slow down' signal may be displayed as one yellow light through the first lamp 301 and one green light through the third lamp 303, and in this case, the train can depart and pass the corresponding signal.

However, in the '5-point section', it is basically allowed to pass at a speed of approximately 105 km/h or less, as the signal for the next section is likely to be 'Caution'.

In the '4-point section', passing at a speed of approximately 65 km/h or less is permitted as the next signal is likely to be 'Caution'.

Furthermore, the 'proceed' signal can be displayed as a single green color through the third lamp 303, and in this case, the train can depart and pass the signal, and the train can proceed as best as the external factors such as the track and vehicle allow. Passing at speed is permitted.

Meanwhile, Figures 3c and 3d show a state in which a 'stop' signal is displayed according to the color-light signal member 300 as a complex departure signal provided on each track in the station, and in this case, the driving member of the present invention (201) can lower the arm neck (202) to block exposure of the arm neck (202) at the rear of the color light signal member (300).

And, when the 'stop' signal displayed by the color signal member 300 continues for a long time and is replaced by a stop signal by the arm tree 202, it is driven according to the operation of the control member 101. The member 201 raises the arm neck 202 to form a right angle with the color-light signal member 300, and at the same time, the second lamp 302 displaying the stop signal turns off.

As described above, the arm tree 202 raised to display the stop signal must be made of a material with high reflectivity, so it must be able to strongly reflect the light of the train's headlights, and has excellent photoluminescence so that it can be easily identified even at night. This is desirable.

Meanwhile, the control member 101 is buried under the track with the power saving pedal switch 102 and the release pedal switch 103 exposed to the ground, and is connected to the driving member 201, the color signal member 300, and the rail and track. The circuits 401a and 401b are connected by a cable 104 to transmit voltage for raising and lowering the arm tree 201.

Here, when the device is to be inspected or the power-saving state and the power-saving released state are to be artificially manipulated by the engineer or a worker dispatched to the scene, the power-saving pedal switch (102) or the release pedal switch (103) exposed on the ground ) can be performed by stepping on it with your foot.

In the present invention, the rail and track circuits 401a and 401b detect whether both sides of the rails constituting the track circuits 401a and 401b are short-circuited by the wheelset of the railway vehicle, as shown in FIG. 4, and detect whether the train is in the corresponding section. To determine entry, the track circuits 401a and 401b are installed segmentally at certain distances, and the signal displayed by the railway signal basically reflects the train occupancy detected in each track circuit.

Based on Figure 4b, the right direction of the composite railway signal according to the present invention is the inner room of the departure signal and the area protected by the signal, and the signal displayed by the signal is the state of the track circuit 401b attached to the inner room of the signal. This is a reflected result, and the condition of the signal determines whether the train will pass the signal and enter the inner room.

And, based on Figure 4b, the left direction of the composite railway signal according to the present invention is outside the departure signal and is an area where the train can stop outside the signal when the signal displays a 'stop' signal. A track circuit (401a) is also attached to the outside of the track, so the controller can check whether a train is stopped on the track.

When the track circuit 401a outside the starting signal is short-circuited by the wheelset, the control member 101 of the present invention wakes up from the power saving state, lowers the arm 202, and transmits the color-equipped signal of the present invention as a conventional color-equipped signal. A predetermined signal can be displayed through the member 300.

Meanwhile, the lifting and lowering of the arm tree 202 in the driving member 201 of the present invention is accomplished by the DC motor 501 built into the driving member 201, as shown in Figure 5. The DC motor 501 rotates The direction may vary depending on the voltage polarity applied to the power line 509.

If the voltage of the power line 509 is positive compared to the ground line 510 of the driving member 201, the DC motor 501 rotates in the direction of lowering the arm 202, and compared to the ground line 510 If the voltage of the power line 509 is a negative voltage, the DC motor 501 rotates in a direction to raise the arm 202.

The rotation speed of the DC motor 501 can be reduced according to the ratio of the first gear 502 and the second gear 503, and the DC motor 501 is coupled to the first gear 502 with a relatively small diameter. The arm 202 can be attached to the second gear 503, which has a relatively large diameter, and the second gear 503 has sufficient rotational force to elevate the arm 202 due to the deceleration action of the gear. This can be formed.

As described above, the iron piece 504 is coupled to the second gear 503, and the iron piece 504 moves the first switch 505 and the second switch 506 according to the rotation of the gears 502 and 503. In changing the contact point, the contact state of each switch 505 and 506 is used to detect whether the arm neck 202 has completely risen or completely fallen.

The first switch 505 and the second switch 506 may operate as, for example, a SPDT (Single Pole Double Throw) switch, each with three electrodes (contacts, 505a, 505b, 505c / 506a, 506b, 506c). It may be in the form of having .

When the arm neck 202 is fully raised, the iron piece 504 closes the gap between the contact point 505a and the contact point 505b in the first switch 505, and opens the gap between the contact point 505a and the contact point 505c. .

At this time, in the second switch 506, the contact point 506a and the contact point 506b are opened, and the contact point 506a and the contact point 506c are closed.

When the arm 202 is completely lowered, the iron piece 504 opens the gap between the contact point 505a and the contact point 505b in the first switch 505, closes the gap between the contact point 505a and the contact point 505c, and closes the second switch 505. In the switch 506, the contact point 506a and the contact point 506b are closed, and the contact point 506a and the contact point 506c are open.

Here, when the arm 202 is fully raised, the iron piece 504 is caught by the first stopper 508a, which means that when the power to the driving member 201 is cut off, the arm 202 automatically lowers by gravity. It serves to fix the second gear 503 to prevent it from happening.

And, when the arm tree 202 is completely lowered, the iron piece 504 is caught by the second stopper 508b, which prevents the arm tree 202 from shaking due to wind or vibration when the power to the driving member 201 is cut off. It serves to fix the second gear 503 so that it is not damaged.

Meanwhile, when a failure occurs in the driving member 201 of the present invention and the arm tree 202 cannot be raised or lowered, the above-described mainspring spring 507 uses its own tension to replace the DC motor 501 with the first gear. (502) is rotated in the direction in which the arm arm (202) rises.

When the arm tree 202 is fully raised, the iron piece 504 is caught by the first stopper 508a and the arm tree 202 is fixed, so that the engineer and related workers can confirm that an abnormality has occurred in the signal display of the departure signal.

And, when a negative voltage is applied to the power line 509, the DC motor 501 generates a rotational force stronger than the force with which the second stopper 508b holds the iron piece 504 installed on the second gear 503. The output is output and the first gear 502 is continuously rotated in the direction in which the arm neck 202 rises.

The rotation of this DC motor 501 causes the iron piece 504 installed on the second gear 503 to contact the first switch 505, so that the gap between the contact point 505a and the contact point 505b is closed, and the contact point 505a and This continues until the contact point 505c opens.

In addition, when a positive (+) voltage is applied to the power line 509, the DC motor 501 generates a rotational force stronger than the force with which the first stopper 508a holds the iron piece 504 installed on the second gear 503. output and continuously rotate the first gear 502 in the direction in which the arm 202 descends.

The rotation of this DC motor 501 causes the iron piece 504 installed on the second gear 503 to touch the second switch 506, so that the gap between the contact point 506a and the contact point 506b is closed, and the contact point 506a and This continues until the contact point 506c opens.

On the other hand, the driving member 201 of the present invention may be configured to further include a heating wire 512 that can heat the interior, especially in the winter, when the first gear 502 and the second gear 503 are damaged by moisture. Alternatively, since the arm tree 202 may be frozen and the arm tree 202 cannot be raised and lowered smoothly, it can be heated according to the surrounding temperature by operating the provided heating wire 512.

As shown in Figure 6, the present invention can be configured to further include a control circuit built into the driving member 201 to control the operation of the DC motor 501. This control circuit includes the first relay 601 and the second relay 601. A relay 602 may be provided.

The first relay 601 supplies current to the DC motor 501 while maintaining the excited state while the arm arm 202 is lowered, and is deactivated when the arm arm 202 is completely lowered. It is normally open and closes when excited. It includes NO (Normal Open) contacts and also NC (Normal Close) contacts that are normally closed but open when energized.

The second relay 602 supplies current to the DC motor 501 while maintaining the excited state while the arm arm 202 rises, and is deactivated when the arm arm 202 is fully raised. Like the first relay 601, the second relay 602 supplies current to the DC motor 501. It contains a NO (Normal Open) contact that is normally open and closes when energized, and an NC (Normal Close) contact that is normally closed and opens when energized.

When the control member 101 supplies a negative voltage to the power line 509 of the driving member 201 in order to raise the arm tree 202, the driving member 201 operates through the diode D1, The negative (-) power is blocked and the negative (-) power is accepted through the diode (D2), and excessive current is limited by the resistor (R2).

On the other hand, if the arm 202 is not raised, the iron piece 504 is not in contact with the first switch 505, so the contact point 505a and the contact point 505c of the first switch 505 are closed, In order to prevent an error in which the raising and lowering operations of the arm arm 202 are performed simultaneously, the NC (Normal Close) contact of the first relay 601 of the driving member 201 must be open.

To prevent the simultaneous operation of the arm 202 in raising and lowering, both the first relay 601 and the second relay 602 must be deactivated or mutually exclusive. Referring to FIG. 6, the first relay 601 When (601) is energized, the NC (Normal Close) contact linked to it opens to block the energization of the second relay 602. Conversely, when the second relay 602 is energized, the NC (Normal Close) contact linked to it opens. It must be opened to block the woman of the first relay (601).

The negative (-) power that passes through the diode (D2) and resistor (R2) from the power line 509 passes through the contacts 505a and 505c and the NC (Normal Close) contact of the first relay 601 to the second relay. After exciting the relay 602, it is transmitted to the electrode 501a connected to the DC motor 501.

As the second relay 602 is excited, the NO (Normal Open) contact is placed in the path directly leading from the power line 509 to the electrode 501a of the DC motor 501 via the diode (D2) and resistor (R4). As it closes, more current is supplied to the DC motor 501 through this path.

In order to prevent the first relay 601 from being unexpectedly energized through the contact point 506a and contact point 506c attached to the second switch 506 while the arm 202 is rising, the first relay 601 ) so that the NC (Normal Close) contacts of the second relay 602 arranged before and after are opened.

When the arm 202 fully rises, the iron piece 504 contacts the first switch 505 and opens between the contact point 505a and the contact point 505c. Accordingly, the second relay 602 is deactivated, and the second relay 602 is deactivated. The NO (Normal Open) contact linked to the relay 602 is opened and the NC (Normal Close) contact is closed.

Subsequently, the NO (Normal Open) contact located in the path directly leading from the power line 509 to the electrode 501a of the DC motor 501 via the diode (D2) and resistor (R4) opens, and the DC motor 501 operates. stop.

In addition, the NC (Normal Close) contacts arranged before and after the first relay 601 and linked to the second relay 602 are closed, so that the first relay 601 is ready to be excited when the arm 202 needs to be lowered. will be completed.

When the negative voltage for raising the arm 202 is re-transmitted from the control member 101 while the arm 202 is fully raised, the first switch 505 is already activated by the iron piece 504. Since the contact point 505a and the contact point 505c are open, the second relay 602 cannot be excited again, but since the contact point 505a and the contact point 505b of the first switch 505 are closed, the second relay 602 cannot be excited again. Thus, a negative voltage is returned to the response line 511 of the driving member 201, which implements the purpose of allowing the control member 101 to know that the arm neck 202 has already risen. It was constructed for.

When the control member 101 supplies a positive (+) voltage to the power line 509 of the driving member 201 to lower the arm tree 202, the driving member 201 generates positive (+) voltage through the diode D1. It accepts +) power and blocks positive (+) power through diode (D2), and excessive current is limited by resistor (R1).

If the arm 202 is not lowered, the iron piece 504 is not in contact with the second switch 506, so the gap between the contact point 506a and the contact point 506c of the second switch 506 is closed, and the arm arm ( In order to prevent an error in which the rising and falling operations of 202) are performed simultaneously, the NC (Normal Close) contact of the second relay 602 must be open.

The positive power from the power line 509 through the diode D1 and the resistor R1 passes through the contact points 506a, 506c, and the NC (Normal Close) contact point of the second relay 602. After exciting the relay 601, it is transmitted to the electrode 501a connected to the DC motor 501.

As the first relay 601 is excited, the NO (Normal Open) contact located in the path directly leading from the power line 509 to the electrode 501a of the DC motor 501 via the diode (D1) and resistor (R3) As it closes, more current is supplied to the DC motor 501 through this path.

In order to prevent the second relay 602 from being unexpectedly energized through the contact point 505a and contact point 505c attached to the first switch 505 while the arm 202 is lowered, the second relay 602 and The NC (Normal Close) contacts of the first relay 601 arranged front and rear open.

When the arm 202 is completely lowered, the iron piece 504 contacts the second switch 506 and opens between the contact point 506a and the contact point 506c. Accordingly, the first relay 601 is deactivated, and the first relay 601 is deactivated. The NO (Normal Open) contact linked to the relay 601 opens and the NC (Normal Close) contact is closed.

Subsequently, the NO (Normal Open) contact located in the path directly leading from the power line 509 to the electrode 501a of the DC motor 501 via the diode D1 and the resistor R3 is opened, and the DC motor 501 operates. will stop.

In addition, the NC (Normal Close) contact linked to the first relay 601 arranged before and after the second relay 602 is closed, so that the second relay 602 is ready to be excited when the arm 202 needs to be raised. will be completed.

When the positive (+) voltage for lowering the arm arm 202 is re-transmitted through the control member 101 in a state in which the arm arm 202 is completely lowered, the second switch 506 is already operated by the iron piece 504. ) is open between the contact points 506a and 506c, so the first relay 601 is not energized again, but since the contact points 506a and 506b of the second switch 506 are closed, Through this, positive voltage is returned to the response line 511 of the driving member 201, and this serves the purpose of allowing the control member 101 to know that the arm tree 202 has already descended. It is designed to be implemented.

After the arm neck 202 is completely raised or lowered, mechanical fixation is fastened between the iron piece 504 and the first stopper 508a or the iron piece 504 and the second stopper 508b, so there is no need to use the power line 509 anymore. There is no need to apply voltage.

As shown in FIG. 6, the control circuit of the driving member 201 may include a thermistor 603 and a triac 604.

The thermistor 603 has the characteristic that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. When a positive (+) or negative (-) voltage is supplied to the power line 509, the driving member ( If the temperature of 201) decreases excessively, the resistance of the thermistor 603 increases and the potential difference between the two electrodes increases.

This potential difference is transmitted to the gate terminal of the triac 604. When the voltage exceeds a certain level, breakdown occurs inside the triac 604 and current is supplied to the hot wire 512 through the resistor (R9).

The triac 604, which operates the heat wire due to breakdown, maintains the breakdown state until the power supplied through the power line 509 is stopped, and the heat generated at this time is transferred to the first gear 502 and the second gear 503. ) is engaged and the frozen state is relieved by warming the part where the arm 202 moves.

Typically, the triac 604 performs a switching action without distinguishing between positive (+) voltage or negative (-) voltage, so the triac 604 attached to the driving member 201 is connected to the arm arm 202. The switching action can be performed both for the case where the arm is rising and for the case where the arm arm is descending.

As shown in Figure 7, the present invention can be configured to include a control circuit provided in the control member 101 to control the operation of the driving member 201 and to control whether the color signal member 300 is activated or deactivated. there is.

As described above, the present invention displays departure conditions on the train through the color-light signal member 300 in the same manner as before, and when a stop signal is displayed for a long time, it is converted into a stop signal by the arm tree 202. Instead, it provides two states, a 'sleep state' that enters a state in which electricity is no longer consumed, and FIG. 7 shows that the arm 202 is fully raised and enters a power save state.

Meanwhile, the control member 101 can operate in conjunction with a signaling device already installed on each track within the railway station through a control circuit, and the input that the control member 101 receives from the previously installed signaling device is shown in FIG. 7. If you think about it, it could be as follows.

Here, 'R IN' is an input terminal where a high voltage is input when the pre-installed signal device wants to display a 'stop' signal on the color-light signal member 300, and otherwise is equal to the ground voltage. am.

And, 'YY IN' is an input terminal through which a high voltage is input when the pre-installed signal device wants to display a 'boundary' signal on the color-equipped signal member 300, and otherwise becomes the same as the ground voltage.

In addition, 'Y IN' is an input terminal through which a high voltage is input when the pre-installed signal device wants to display a 'caution' signal on the color-light signal member 300, and otherwise becomes the same as the ground voltage.

In addition, 'YG IN' is an input terminal through which a high voltage is input when the pre-installed signal device wants to display a 'slow down' signal on the color-light signal member 300, and otherwise becomes the same as the ground voltage.

In addition, 'G IN' is an input terminal through which a high voltage is input when the pre-installed signal device wants to display a 'progress' signal on the color-light signal member 300, and otherwise becomes the same as the ground voltage.

In addition, 'Vcc' is a power input terminal for operating the control member 101, and 'GND' is a ground terminal for the control member 101 to share a reference potential with an already installed signal device.

Meanwhile, the output transmitted by the control member 101 of the present invention to the color signal member 300 is the same as the input received from the signal device in which the above-described control member 101 is already installed. Referring to FIG. 7, As follows.

Here, 'R OUT' outputs high voltage to display a stop signal to the color-light signal member 300 only when the control member 101 is not in a power saving state when the pre-installed signaling device wants to display a stop signal. Otherwise, it is an output terminal that becomes equal to the ground voltage.

In addition, 'YY OUT' is an output terminal that transmits high voltage to the color-equipped signal member 300 only if the control member 101 is not in a power saving state when the pre-installed signaling device transmits high voltage to display a 'warning' signal. am.

In addition, 'Y OUT' is an output terminal that transmits high voltage to the color-light signal member 300 only when the pre-installed signaling device transmits high voltage to display a 'caution' signal, only when the control member 101 is not in a power saving state. am.

In addition, 'YG OUT' is an output terminal that transmits high voltage to the color signal member 300 as is when the pre-installed signal device transmits a high voltage to display a 'deceleration' signal, only when the control member 101 is not in a power saving state. am.

In addition, 'G OUT' is an output terminal that transmits high voltage to the color-light signal member 300 only when the pre-installed signaling device transmits high voltage to display a 'progress' signal, only when the control member 101 is not in a power saving state. am.

In the same manner as above, referring to FIG. 7, the input terminal through which the control circuit of the control member 101 can be connected to the outside in order to test the function provided by the control member 101 of the present invention will be described as follows.

Here, 'SLEEP' is an input terminal to which a high voltage is input when it is desired to immediately put the departure signal to which the complex railway signal according to the present invention is applied into a sleep state, and otherwise becomes the same as the ground voltage.

And, 'WAKE' is an input terminal where a high voltage is input when it is desired to immediately wake up the departure signal to which the complex railway signal according to the present invention is applied from the sleep state, and otherwise, it is the same as the ground voltage.

Meanwhile, in FIG. 7, reference numeral 509 outputs a negative (-) voltage when the control member 101 wants to raise the arm arm, and outputs a positive (+) voltage when the control member 101 wants to lower the arm arm. This terminal outputs and is equal to the ground voltage in other cases.

In addition, reference numeral 510 is a ground terminal for sharing a reference potential between the control member 101 and the driving member 201, and reference numeral 511 is a control member ( When 101) continues to output a negative voltage to raise the arm 202, or when the arm 202 is already lowered, the control member 101 continues to lower the arm 202 by outputting a positive voltage. When outputting a voltage of +), it is an input terminal that receives the voltage returned by the driving member 201 to indicate that the arm 202 has already risen, and in other cases, it is the same as the ground voltage.

The above-mentioned input terminal 511 is connected in parallel to an external switch separately from the driving member 201, and provides an emergency direct connection between the pre-installed signaling device and the color-light signaling member 300 without waiting for the operation of the driving member. It can also be applied as a bypass signal.

In a state other than the power saving state, the control member 101 transmits the signal desired to be displayed by the previously installed signal device to the color-light signal member 300 as is.

For example, when a pre-installed signaling device wants to display a 'stop' signal on the starting signal, high voltage is transmitted to 'R IN' of the control member 101, which is directly transmitted to 'R OUT' of the control member 101. It is sent, and is used to turn on the red second lamp 302 attached to the color signal member 300.

The SPST (Single Pole Single Throw) switch 701a located in the path through which voltage is transmitted from 'R IN' to 'R OUT' is closed because the control member 101 is not in a power saving state.

When the pre-installed signaling device wants to display a 'warning' signal on the departure signal, high voltage is transmitted to the 'YY IN' of the control member 101, which is directly sent to the 'YY OUT' of the control member 101, which It is used to light the yellow first lamp 301 and the yellow fourth lamp 304 attached to the color signal member 300.

The SPST switch 701a located in the path through which voltage is transmitted from 'YY IN' to 'YY OUT' is closed because the control member 101 is not in a power saving state.

When the pre-installed signaling device wants to display a 'caution' signal on the departure signal, high voltage is transmitted to the 'Y IN' of the control member 101, which is directly sent to the 'Y OUT' of the control member 101, which It is used to light the yellow first lamp 301 attached to the color signal member 300.

The SPST switch 701a located in the path through which voltage is transmitted from 'Y IN' to 'Y OUT' is closed because the control member 101 is not in a power saving state.

When the pre-installed signaling device wants to display a 'slow down' signal on the departure signal, high voltage is transmitted to the 'YG IN' of the control member 101, which is directly sent to the 'YG OUT' of the control member 101, which It is used to light the yellow first lamp 301 and the green third lamp 303 attached to the color signal member 300.

The SPST switch 701a located in the path through which voltage is transmitted from 'YG IN' to 'YG OUT' is closed because the control member 101 is not currently in a power saving state.

When the pre-installed signaling device wants to display a 'go' signal on the departure signal, high voltage is transmitted to 'G IN' of the control member 101, which is directly sent to 'G OUT' of the control member 101, which It is used to light the green third lamp 303 attached to the color signal member 300.

The SPST switch 701a located in the path through which voltage is transmitted from 'G IN' to 'G OUT' is closed because the control member 101 is not currently in a power saving state.

If the pre-installed signaling device displays a 'stop' signal on the departure signal for a long time, a portion of the current supplied to the color-light signal member 300 to display this is used in the resistor (R1), diode (D1), and variable resistor (VR1). ) reaches the capacitor 704, the capacitor 704 is charged and the potential difference between the two electrodes increases, and the speed at which the capacitor 704 is charged can be adjusted through the variable resistor (VR1).

At this time, the SPST switch 701a placed between the diode D1 and the variable resistor VR1 is closed because the control member 101 is not in a power saving state.

Meanwhile, the variable resistor (VR2) and the resistor (R19) are connected in series and perform the function of a voltage divider for the voltage of the power source (Vcc) supplied to the control member 101 of the present invention.

The magnitude of the voltage applied to the resistor (R19) can be adjusted through the variable resistor (VR2), which forms the voltage of the capacitor 704 that serves as a standard for the control member 101 to enter the power saving mode.

At this time, the SPST switch 701a placed between the power source Vcc and the variable resistor VR2 is closed because the control member 101 is not in a power saving state.

As a long-time stop signal is displayed, the rising voltage of the capacitor 704 and the reference voltage of the resistor R19 obtained by the action of the voltage divider are transmitted to the operational amplifier (OPAMP1).

When the voltage of the capacitor 704 is higher than the voltage of the resistor R19, the operational amplifier (OPAMP1) outputs a positive (+) voltage to the output terminal.

The diode (D8) performs a rectification action to take only the positive (+) voltage among the voltages output from the operational amplifier (OPAMP1), and the resistor (R22) clearly detects the positive (+) voltage or zero (0) voltage. It is a pull-down resistor to make it work.

At this time, the SPST switch 701a placed between the power source Vcc and the resistor R21 is closed because the control member 101 is not in a power saving state and supplies power to operate the operational amplifier OPAMP1.

When the output of the operational amplifier (OPAMP1) overcomes the barrier potential of the diode (D8) and begins to be detected as a positive (+) voltage, the maximum current is limited by the resistor (R16) and then excites the slow rise relay (703). I order it.

Meanwhile, another method of forming a positive (+) voltage for exciting the arm lifting relay (703) is for the controller to apply a positive (+) voltage to the 'SLEEP' terminal of the control member (101) through a predetermined operation. It can be transmitted directly, and in this case, the current flows through the resistor (R17) and the diode (D7) and the arm rising relay (703) is excited.

In addition, related personnel such as station staff, facility staff, and train drivers who can be dispatched near the departure signal can step on the power saving pedal switch 102 attached to the control member 101, and in this case, the power saving pedal switch 102 is switched from the power source Vcc to the resistor R8. And the electric current flows through the power saving pedal switch 102 whose contact point is closed, and the arm raising relay 703 is excited.

The SPST switch 701a located on the path through which the current that can flow through the two paths described above reaches the arm lifting relay 703 is closed because the control member 101 is not in a power saving state.

When the arm raising relay (703) is excited in the same manner as described above, the NO (Normal Open) contact (703a) linked here is closed and the arm raising relay (703) is connected from the power source (Vcc) via the resistor (R15). An electric circuit is formed in which a sufficient amount of current can be stably supplied.

At this time, the SPST switch 701a placed between the power source Vcc and the resistor R15 is closed because the control member 101 is not in a power saving state.

Meanwhile, the negative (-) voltage required for the driving member 201 of the present invention to raise the wrist 202 can be formed through an inverting amplifier consisting of an operational amplifier (OPAMP2) and a resistor (R10).

The operational amplifier (OPAMP2) is supplied with power through a resistor (R9). At this time, the SPST switch (701a) placed between the power source (Vcc) and the resistor (R9) is closed because the control member (101) is not in a power saving state.

When the NO (Normal Open) contact (703a), which is placed before and after the operational amplifier (OPAMP2) and linked to the arm rising relay (703), is closed, sound ( A voltage of -) is supplied to the driving member 201 through the driving member power line 509, and the driving member 201 raises the arm neck 202 through the operation described above.

If the arm 202 attached to the drive member 201 has completed its rise or is already in a state of being raised, the negative (-) voltage supplied to the power line 509 of the drive member 201 is Returning to the response line 511, this voltage is blocked at the diode D10, is accepted through the diode D9, and excites the power saving relay 701c through the resistor R23.

When the power saving relay (701c) is excited, it opens the SPST switch (701a) and closes the SPST switch (701b). Since the two types of SPST switches (701a and 701b) are mechanical switches, they do not change even if the power saving relay (701c) is deactivated. The state can be maintained permanently.

More specifically, by excitation of the power saving relay 701c, the path directly connecting the pre-installed signaling device and the color-light signal member 300 is blocked, and the path between 'R IN' and 'R OUT', The path between 'YY IN' and 'YY OUT', the path between 'Y IN' and 'Y OUT', the path between 'YG IN' and 'YG OUT', and the path between 'G IN' and 'G OUT' ' Since the path between them is blocked, the color-equipped signal member 300 not only turns off, but also no longer consumes power.

In addition, the path through which negative voltage is supplied from the power source (Vcc) to the driving member 201 through the resistor (R9) and the operational amplifier (OPAMP2) is blocked, so the driving member 201 no longer consumes power. It won't happen.

In addition, the path through which voltage is applied from the power source (Vcc) to the resistor (R19) through the variable resistor (VR2) is blocked, so these resistors no longer consume power.

In addition, the path where power is supplied from the power source (Vcc) to the operational amplifier (OPAMP1) through the resistor (R21) is blocked, so the operational amplifier (OPAMP1) no longer consumes power.

In addition, the circuit in which current is supplied from the power source (Vcc) to the small arm rising relay 703 through the resistor (R15) is blocked, so that the small arm rising relay 703 achieves its predetermined purpose and is deactivated.

Along with this, The path of the current that can excite the arm raising relay 703 from the power source (Vcc) via the resistor (R8) and the power saving pedal switch 102 is blocked, which causes the control member 101, which has already entered a power saving state, to be blocked. This has the effect of preventing the above-described operation for entering the power saving state from being repeated by re-handling the power saving pedal switch 102.

Furthermore, the path of the current that can excite the slow neck rising relay 703 via the resistor (R17) and diode (D7) at the 'SLEEP' input terminal is blocked, which means that the control member 101 that has already entered a sleep state is blocked. This has the effect of preventing the above-described operation for entering the power saving mode from being repeated by re-instructing the controller to enter the power saving mode.

Accordingly, the control member 101 and the driving member 201 of the present invention enter a power saving state in which no further power is consumed together with the color-light signal member 300.

Meanwhile, due to excitation of the power saving state relay (701c), the SPST switch (701a) placed in the path charging the capacitor (704) at 'R IN' via the resistor (R1), diode (D1), and variable resistor (VR1) ) is opened, but the SPST switch (701b) located in the path where the capacitor (704), the resistor (R18) and ground are connected to each other is closed, so that the capacitor (704) is completely discharged and the time at which the stop signal appears can be measured again. Finish your preparations.

Then, the SPST switch 701b located in the path from the power supply Vcc to the arm lowering relay 702 via the resistor R14 is closed, thereby completing preparations for the arm arm 202 to descend.

In addition, there is a path through which current can be supplied from 'YY IN' to the lowering relay 702 via resistor (R2), diode (D2), and resistor (R13), and a resistor (R3) from 'Y IN', A path through which current can be supplied to the lowering relay 702 via the diode (D3) and resistor (R13), and from 'YG IN' via the resistor (R4), diode (D4), and resistor (R13). There is a path through which current can be supplied to the arm lowering relay (702), and a current can be supplied from 'G IN' to the arm lowering relay (702) via the resistor (R5), diode (D5), and resistor (R13). A path through which current can be supplied from 'WAKE' to the slow-down relay 702 via the resistor (R6), diode (D6), and resistor (R13), and a path through which current can be supplied from the power source (Vcc) to the resistor (R7). , the SPST switch (701b) located in the path through which current can be supplied to the arm lowering relay (702) via the release pedal switch (103), resistor (R6), diode (D6), and resistor (R13) is closed, It wakes up from the sleep state and prepares to lower the arm.

In addition, the SPST switch (701b) located in the path through which current can be supplied from the power source (Vcc) to the resistor (R25) and the operational amplifier (OPAMP3) is closed so that the driving member 201 can lower the arm neck 202. Prepare to supply positive (+) voltage.

As a result, the control member 101 and the driving member 201 of the present invention can detect a 'stop' signal that persists for a long time after preparing to wake up from the sleep state and waking up, and enter the sleep state by repeating the above-described process. The preparation will be completed.

As described above, the color signal member 300 and each component of the present invention that is ready to wake up from the sleep state no longer consumes power.

Meanwhile, in order for the control member 101 of the present invention to wake up from the power saving state, one of the following conditions must be satisfied: when the pre-installed signal device wants to display a 'warning' signal on the color-light signal member 300 , current flows into the input 'YY IN' of the control member 101, and the slow-down relay 702 is excited via the resistor (R2), diode (D2), and resistor (R13).

And, when the pre-installed signaling device wants to display a 'caution' signal on the color signal member 300, current flows into the input 'Y IN' of the control member 101, and the resistor (R3) and diode (D3) ) and the full neck lowering relay (702) is excited via the resistor (R13).

In addition, when the pre-installed signal device wants to display a 'deceleration' signal on the color signal member 300, current flows into the input 'YG IN' of the control member 101, and the resistor (R4) and diode (D4) ) and the full neck lowering relay (702) is excited via the resistor (R13).

In addition, when the pre-installed signaling device wishes to display a 'progress' signal on the color-equipped signal member 300, current flows into the input 'G IN' of the control member 101, and the resistor (R5) and diode (D5) ) and the full neck lowering relay (702) is excited via the resistor (R13).

In addition, when the controller directly handles a certain device to release the power saving state of the control member 101, current flows into the input 'WAKE' of the control member 101 from the previously installed control-related equipment, and the resistor (R6) , the slow-down relay 702 is excited via the diode D6 and the resistor R13.

In addition, if a station employee, facility employee, or engineer with direct access to the signal handles the release pedal switch (103) attached to the control member (101), the resistor (R7) from the power source (Vcc) is released. The arm lowering relay 702 is excited via the pedal switch 103, resistor (R6), diode (D6), and resistor (R13).

When one of the above-mentioned conditions is satisfied and the normal arm lowering relay 702 is excited, NO (Normal Open) is placed in the path where current is supplied from the power supply (Vcc) to the normal arm lowering relay 702 via the resistor (R14). As the contact point closes, sufficient and stable current is supplied to the arm lowering relay 702 and the excited state is maintained.

And, the NO (Normal Open) contact located in the path where the current is supplied from the power source (Vcc) to the non-inverting amplifier circuit consisting of the operational amplifier (OPAMP3), resistor (R11), and resistor (R12) via the resistor (R25). As it closes, a positive (+) voltage is supplied from the non-inverting amplification circuit to the power line 509 of the driving member 201, and at this time, the driving member 201 lowers the arm 202 through the operation described above.

If the arm 202 attached to the driving member 201 has completed lowering or is already lowered, the positive (+) voltage supplied to the power line 509 of the driving member 201 is the response of the driving member 201. Returning to line 511, this voltage is blocked at diode D9 and accepted through diode D10 to excite release relay 701d through resistor R24.

When the release relay (701d) is excited, it closes the open SPST switch (701a) and opens the closed SPST switch (701b). Since the two types of SPST switches (701a and 701b) are mechanical switches, the release relay (701d) Even if it is demagnetized, the changed state can be maintained permanently.

More specifically, by excitation of the release relay 701d, the path connecting the pre-installed signal device and the color-equipped signal member 300 is directly connected, and the path between 'R IN' and 'R OUT' and 'YY The path between 'IN' and 'YY OUT', the path between 'Y IN' and 'Y OUT', the path between 'YG IN' and 'YG OUT', and the path between 'G IN' and 'G OUT' In addition, since each closed SPST switch 701a is directly connected to the path, the previously installed signaling device can display a signal to the train on the color-light signal member 300 in the same manner as before.

In addition, the path through which positive voltage is supplied from the power source (Vcc) to the driving member 201 through the resistor (R25) and the operational amplifier (OPAMP3) is blocked, so the driving member 201 no longer consumes power. It won't happen.

In addition, a voltage path is connected from the power source (Vcc) to the resistor (R19) through the variable resistor (VR2), and these resistors form a reference voltage for entering the power saving mode through a voltage distribution function.

In addition, the path where power is supplied from the power source (Vcc) to the operational amplifier (OPAMP1) through the resistor (R21) is connected, and the operational amplifier (OPAMP1) starts operating.

In addition, the circuit in which current is supplied from the power source (Vcc) to the small arm lowering relay 702 through the resistor (R14) is blocked, so that the small arm lowering relay 702 achieves its predetermined purpose and is deactivated.

At the same time, the path of the current that can excite the arm lowering relay 702 from the power source Vcc via the resistor R7 and the release pedal switch 103 is blocked, which means that the control member 101 waking up from the power saving state is blocked. ) has the effect of preventing the above-described operation for power saving from being repeated again by re-handling the release pedal switch 103.

Furthermore, the path of the current that can excite the arm lowering relay 702 via the resistor (R6) and diode (D6) at the 'WAKE' input terminal is blocked, which causes the control member 101 that wakes up from the power saving state. This has the effect of preventing the above-described operation for terminating sleep from being repeated again by re-instructing the controller to wake up from the sleep state.

As a result, the control member 101 of the present invention directly connects the pre-installed signal device and the color-light signal member 300 and configures a circuit to display the signal in the same manner as before, and the drive member 201 is raised. Not only does the arm neck (202) lower, but it is also completely hidden behind the color-light signal member (300).

The above-mentioned terminal 'WAKE' can be connected to the track circuit (401a) outside the signal in addition to the controller's power saving instruction. Based on this, when a train enters the track to which the present invention is applied, the present invention automatically saves power on the corresponding signal. It can be configured to wake up from this state.

Meanwhile, due to excitation of the release relay (701d), the SPST switch (701a) placed in the path of charging the capacitor (704) at 'R IN' via the resistor (R1), diode (D1), and variable resistor (VR1) is closed, and the SPST switch (701b) located in the path where the capacitor 704, the resistor (R18) and ground are connected to each other is opened, so that the capacitor 704 stops the previously installed signal device at the color signal member 300.
