Next, the operation and effects of the present invention configured as described above will be described.

First, when the power plug 20 is connected to the AC power line, and the main switch 25 is switched on, the DC power supply 28 receiving the AC power is rectified to a DC of a level required by each component. While supplying to the control part 100, the direct current required for each component is supplied.

In this state, when the red light 3b is turned on in the traffic light 3 by the traffic light light discriminating means 200, the pedestrian has crossed the safety line 4 in the crosswalk 1 by the human body detecting means 300. Detect whether there is.

The detection of the presence of a pedestrian in the safety line 4 in the crosswalk 1 when the red traffic light 3b is turned on is the drive control signal of the optical sensor 310 output from the output port P01 of the controller 100. When outputting the voltage, the bias voltage is applied to the base of the transistor Q8 through the bias resistor R2l, so that the transistor Q8 is switched on, thereby the resistor R19, the light emitting diode PD, and the resistor. Since the current flows through the R23 and the transistor Q8, the light emitting diode PD emits light. Accordingly, the phototransistor PT is switched on to thereby switch the transistor Q7 through the resistors R20 and R21. Is switched on and a signal is input to the input port P11 of the controller 100 so that the controller 100 determines that there is no pedestrian in the safety line 4 of the crosswalk 1. At this time, when there is a pedestrian between the light emitting diode PD, the photo transistor PT, and the optical sensor 310, that is, when there is a pedestrian in the safety line 4, the photo transistor PT of the optical sensor 310 is Since the off state, the control unit 100 determines that there is a pedestrian in the safety line 4.

As described above, when the time for changing from the lighting state of the green signal lamp 3a to the lighting state of the red signal lamp 3b is imminent, the alarm sound generating means 400 outputs an alarm sound to the pedestrian. The alarm sound control signal is output from the output port P05 of 100). The alarm sound control signal is biased by the bias resistors R5 and R6 to switch on the transistor Q3 so that a current flows in the relay coil RY3. Therefore, when the movable contact (a) is in contact with the fixed contact (b), the buzzer driving signal is applied to the buzzer 410 and outputs an alarm sound, thereby preventing the pedestrian from crossing the crosswalk, thereby preventing the elderly from crossing the crosswalk, Prevent traffic accidents for children and the visually impaired.

At the same time, the output port (P08) of the control unit 100 in order to position the blocking rod 700 vertically with respect to the crosswalk 1, that is, to prevent the pedestrians from crossing the crosswalk (1) reverse rod drive signal By outputting and applying a bias voltage to the base of the transistor Q6 through the bias resistors R11 and R12, current flows through the relay coil RY5 so that the movable contact j is brought into contact with the fixed contact k so as to contact the motor. AC power is supplied to 752 to reverse the rotation. Accordingly, the blocking rod 700 is positioned perpendicular to the crosswalk to prevent the pedestrian from crossing the crosswalk.

In addition, when the pedestrian crosses the safety line 4 of the crosswalk when the red traffic light 3b is turned on, the bias resistance of the red light lighting means 500 is output from the output port P03 of the controller 100. By outputting a red light 502 lighting control signal to R1 and R2, the transistor Q1 is switched on so that a current flows in the relay coil RY1, and the movable contact c comes into contact with the fixed contact d. Accordingly, the driver driving the vehicle with the red light 502 turned on may perform a defensive driving at the time of the crosswalk, thereby preventing a traffic accident.

On the contrary, if the pedestrian is not in the safety line 4 of the crosswalk when the red signal lamp 3b is turned on, the bias resistance of the green lamp lighting means 600 is output from the output port P04 of the controller 100. By outputting the lighting control signal of the green lamp 602 to R3 and R4, the transistor Q2 is switched on so that a current flows in the relay coil RY2, and the movable contact e contacts the fixed contact g. . Accordingly, a driver driving a vehicle by turning on the green light 602 may travel with a margin for pedestrian crossing.

When a failure occurs of the red traffic light 3b or the green traffic light 3a, the failure signal of the traffic light fault detection unit 810 causes the failure signal (specifically, the red traffic light 3b or the green traffic light 3a which are turned on at a predetermined time period). The transistor Q10 is switched on by detecting the signal of detecting the lighting signal of the ") and outputting the same to the bias resistors R28 and R29. In this case, a low level signal is input to the input port P15 of the controller 100 to determine whether any one of the traffic lights 3 is broken in the controller 100.

When the pedestrian crossing the safety line 4 of the crosswalk is detected by the human body detecting means 300 when the red traffic light 3b is turned on, the red traffic light 3b is turned on when the green traffic light 3a is turned on. When the time to change to the lighting state of the () is imminent and when at least one of the traffic lights (3) by the traffic light failure detection means 800 is broken, the speaker (speaker) at the output port (P02) of the control unit 100 When a signal for driving control of the device 910 is output, a bias voltage is applied to the base of the transistor Q9 through a bias resistor R26, so that the transistor Q9 is switched on. At this time, a voice control signal is output to the voice output integrated circuit 920 through the output resistor R25 to alert the pedestrian to retreat behind the safety line 4 by voice from the speaker 910, and to the pedestrian the green traffic light 3a. In addition to the alarm to be converted to the lighting of the red traffic light (3b) in the lighting state, at least one of the traffic light (3; specifically, the red traffic light (3b) or the green traffic light (3a)) of the failure to warn the crosswalk Prevent the occurrence of safety accident in (1).

On the other hand, when it is determined that the green signal lamp 3a is turned on by the control unit 100 receiving the signal detected by the signal light determining means 200, the output port (P07, P08) of the bottom section 100 The bias resistors R9 and R10 are outputted by outputting a forward rotation driving control signal of the blocking rod 700 (forward rotation driving signal of the motor 752) to position the blocking rod 700 perpendicularly to the roadway 2. The transistors Q5 and Q6 are switched on by applying a bias voltage to the bases of the transistors Q5 and Q6 through R11 and R12. Accordingly, a current flows through the relay coils RY4 and RY5 to contact the movable contacts g and j with the fixed contacts h and k, respectively, so that the motor 752 is rotated forward to drive the blocking rod 700. Position it perpendicular to (2).

In the above description, the red light lighting detecting means 210 of the signal lamp lighting determining means 200, when the red signal lamp 3b is turned on, the lighting signal of the transistor Q11 through the bias resistors R13 and R14. Since the bias voltage is applied to the base, the transistor Q11 is switched on so that a low level signal is applied to the input port P19 of the controller 100 through an output resistor R15 so that the red signal lamp 3b is turned on. The control unit 100 recognizes that the high level signal is applied to the input port P19 of the control unit 100 through the output resistor R15 when the red signal lamp 3b is not lit. The non-illumination of 3b) is recognized by the controller 100.

The green lamp lighting detecting means 220 of the signal lamp lighting determining means 200 has the base signal of the transistor Q10 through the bias resistors R17 and R18 when the green signal lamp 3a is turned on. Since the bias voltage is applied to the transistor Q10, the transistor Q10 is switched on so that a low level signal is applied to the input port P20 of the controller 100 through the output resistor R16 to turn on the green signal lamp 3a. The controller 100 recognizes the green signal lamp 3a when a high level signal is applied to the input port P20 of the controller 100 through the output resistor R16 when the green signal lamp 3a is not lit. ), The control unit 100 recognizes the non-lighting.

As described above, according to the safety device of the crosswalk according to the present invention, when the pedestrian crosses the safety line of the crosswalk when the red signal light prohibiting the crossing of the pedestrian is turned on, the pedestrian returns to the safety line of the crosswalk. To alert people with a warning and to move the breaker bar vertically to the crosswalk to prevent pedestrians from crossing the road, and when the traffic light of the crosswalk is lit by the green light, Stop moving vehicles on the pedestrian crossing by moving them, and also detect the failure of the traffic lights and alert the pedestrians and drivers to the pedestrians and drivers when the traffic lights in the pedestrian crossing break down, so that frequent traffic accidents in the pedestrian crossing can be left unseen. Also, the signal is almost finished when the green light is almost finished (just before the red light is turned on). The alarm sound generating means warns the pedestrian and the driver with a buzzer sound, and at the same time, the speaker of the guide voice output means is voiced to alert the pedestrian and the driver not to cross the pedestrian crossing quickly. There are many outstanding effects, such as preventing traffic accidents on the sidewalk.
