Hereinafter, the operation control process according to the setting conditions of the signal lighting circuit will be described.

First, the general signal lighting control process is as follows.

In the general signal lighting control process, the vehicle 'green' lamp 110a and the walking 'red' lamp 100b are always lit. For this purpose, the select switch 50 is located in the button circuit. As a result, the power applied in the circuit is transferred to the R5 relay R5 to be excited. As a result, the fifth contact R5 is switched from the A contact to the B contact. The state of the contact A is a state in which power supply is cut off, and the state of the contact B is a state in which power is applied.

Therefore, each contact having a contact A and B contact state is maintained as it is, and only the contact R5 (R5 (2)) is converted from the contact A to the contact B state.

As a result, the first contact point R1 (3), the third contact point R3 (2) and the third point R3 (3), the fourth contact point R4 (4), and the R0 contact point (R0 (3)) connected to the vehicle 'green' lamp 110a ( Since R0 (4) is a contact B, power is applied to turn on the vehicle 'green' lamp 110a. In addition, since the third contacts R3 (2), R3 (3), the fourth contact R4 (4), and the R0 point R0 (4) connected to the walking 'red' lamp 100b are the B contacts, It is applied and the walking 'red' lamp 100b is turned on.

As described above, the present invention is a method in which the traffic light is always lit in green, the pedestrian traffic light is always lit in red, and the user manually controls the signal when necessary.

Next, when the user inputs a manual signal, the signal lighting control process is as follows.

The user selects a ready manual button near the crosswalk. In the circuit of the present invention, PB1 and PB2 buttons are provided as manual buttons. When the user selects the PB1 button and the PB2 button, the contact point is kept in the on state only while the user presses the button, and then immediately turns off. However, after the user selects the button, the button selection state must be maintained for a predetermined time until crossing the crosswalk, so that the state of the first contact point R1 (1) is switched from the contact point A to the contact point B, thereby changing the contact state. Keep it.

As a result, the signal of the manual button selected by the user is continuously input for the set time. At this time, the time set in the relay is an estimated time for the user to cross the pedestrian crossing. As described above, after the state of the first contact R1 (2) is converted to the B contact, the R3 relay RE3 is excited.

On the other hand, the first contact point R1 (3) is converted to the B contact point, and the third contact point R3 (2) is maintained at the contact point B at the A contact point. As a result, the vehicle 'green' lamp 110a connected to the first contact R1 (3) is turned off, and the walking 'red' lamp 100b connected to the third contact R3 (2) is turned on.

As mentioned above, by the excited third relay RE3, the third contact R3 (1) is switched from the A contact to the B contact state. As a result, the power is applied to the yellow lamp 120, the vehicle 'yellow' lamp 120 is turned on. In this state, as the setting time set for the timer has elapsed, the state of the third contact R3 (1) is returned from the contact B to the contact A. Then, the contact T1 (T1) is converted from contact A to contact B, so that the R2 relay (RE2), the T2 timer (TM2) and the T3 timer (TM3) are excited. Accordingly, the operation of the contacts connected to each of the R2 relays RE2, the T2 timer TM2, and the T3 timer TM3 is converted (contact A-> B).

That is, the contact state of the second relay RE2 is converted. When the second contact point R2 (1) is switched from the contact point A to the contact point B, the vehicle 'red' lamp 100a connected to the second contact point R2 (1) is turned on. At the same time, the walking 'green' lamp 110b lights up.

On the other hand, the third contact (R3 (1)) is converted from the contact B to the contact A, the vehicle 'yellow' lamp 120 connected to the third contact (R3 (1)) is turned off. The third contact R3 (2) is also converted from the B contact to the A contact. As a result, the walking 'red' lamp 100b goes out.

The T3 timer contact T3 (1) is converted from the A contact to the B contact, and the power is excited to the F1 timer FM1. When the time set in the F1 timer FM1 is counted and a predetermined time has elapsed, the F1 contact F1 is converted from the A contact to the B contact. Accordingly, the pedestrian 'green' lamp 110b is turned on.

With the walking 'green' lamp 110b lit, the T2 contact T2 is switched from the B contact state to the A contact state. At the same time, the power supply of the R1 relay RE1, the R2 relay RE2, the T1 timer TM1, the T2 timer TM2, and the T3 timer TM3 is cut off.

The R1 contact R1 (1) is converted from the B contact to the A contact. On the other hand, the R1 contact R1 (3) is converted from the A contact to the B contact. As a result, the vehicle 'green' lamp 110a connected to the R1 contact R1 (3) is turned on.

The R2 contact R2 (1) is converted from the B contact to the A contact. As the state of the R2 contact R2 (1) is switched, the vehicle 'red' lamp 100a connected to the R2 contact R2 (1) is turned off, and at the same time, the walking 'green' lamp 110b is turned off. . In addition, the excitation of the F1 timer FM1 is blocked.

The T1 timer contact TM1 is converted from the B contact to the A contact, the T2 contact TM2 is also switched from the A contact to the B contact, and the T3 contact TM3 is converted from the B contact to the A contact. At the same time, the excitation of the F1 timer FM1 is blocked.

Therefore, after the pedestrian selects the manual button, the walking 'green' button 110b is turned on until the pedestrian crosses the crosswalk, and when the contact state conversion on the circuit is finished, the vehicle 'green' button 110a is finally lit. , The walking 'red' button 100b is lit.

In this way, the present invention can control the signal operation of the signal lighting circuit by manual operation, and it is possible to convert the lighting of the pedestrian traffic light and the traffic light according to the user's needs. In addition, the present invention can implement a signal lighting circuit for controlling whether a signal is turned on at low cost by using a relay and a timer without the configuration of an expensive electronic controller.

On the other hand, when a situation such as controlling the entry of the vehicle according to the situation of the road occurs, the traffic light of the road to the 'yellow' lamp lighting control (flashing operation control). To this end, the operation control process of the circuit is performed as follows.

When blinking the select switch is positioned at the blink contact as shown. Since the blinking contact is connected to the fourth relay R4 (1), the fourth relay R4 (1) is excited. Contact A is converted to contact B due to the excitation of the fourth relay R4 (1). As a result, the timer TMR connected to the fourth contact point and the fifth contact point, which are in the B contact state, is excited. In addition, the fourth contact R4 (2) is converted from the A contact to the B contact, so that the FM2 timer connected to the fourth contact R4 (2) is excited. The fourth contact R4 (4) is converted from the B contact to the A contact. Accordingly, the vehicle 'green' lamp 110a and the walking 'red' lamp 100b connected to the fourth contact point R4 (4) are turned off.

On the other hand, the state of the timer relay T is switched from the A contact to the B contact state by the contact change of the timer TMR, and the R0 relay R0 is excited. As a result, contact R0 (R0 (1) is converted from contact B to contact A. And the state of contact R0 (2) changes from contact A to contact B, and the contact R0 (3) also changes from contact A to contact B. On the other hand, the contact R0 (4) is switched from contact B to contact A, and gradually the F2 timer is switched to contact B. As a result, the vehicle 'yellow' lamp 120 lights up.

In addition, unless the manager changes the state of the select switch 50 separately, the vehicle 'yellow' lamp 120 keeps being turned on.

As described above, when the lighting signal is input manually, it is possible to control the lighting of the road and the pedestrian traffic light by the operation of the relay contact relay and the manual switch without having an expensive control device by the input signal. I assume it is a basic technical idea.

The rights of the present invention are not limited to the embodiments described above, but are defined by what is stated in the claims, and those skilled in the art can make various modifications and adaptations within the scope of the rights described in the claims. It is self-evident.

Therefore, the following effects can be expected due to the signal lighting circuit according to the present invention.
