Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a traffic signal control device equipped with a pushbutton device for pedestrians, in which different sounds are generated to inform a blind person of the location of the pushbutton, the acceptance of the pushbutton operation, and the right of way. This device is designed to notify the occurrence of crosswalks, and its purpose is to help blind people crosswalks safely and easily.

Currently, traffic signals at road intersections and the like are designed primarily for visual purposes, and considerations are being made, such as arranging signals with puppet lights for pedestrians at crosswalks.

Currently, measures are taken to assist blind pedestrians by linking signal lights at periodically controlled intersections and playing different songs depending on the direction of traffic, but as a countermeasure for people with disabilities, However, it is still insufficient.

In view of the above points, the present invention utilizes a pedestrian pushbutton device to generate several different audible sounds to make the blind person aware of the location of the pushbutton and to make the operation of the pushbutton easier. Notify the signal controller that it has been accepted,
The system guides the blind person safely to the crosswalk by changing the types of sounds in sequence, such as notifying the user that he or she is allowed to walk toward the crosswalk in the desired direction.

Conventionally, pedestrian pushbuttons are information providing terminals for so-called sensitive traffic signal controllers that control traffic on the road to cross according to pedestrian requests, and are located near the pedestrian waiting position at the end of the crosswalk. It is used to protect pedestrians from crossing the road by temporarily stopping vehicle traffic in the area when a signal is issued by a pedestrian pushing a button.

This pushbutton device generally consists of a pushbutton and an indicator light that indicates that the pedestrian's request has been accepted by the controller, and if necessary, a message is displayed on the external panel saying, ``Crossers, please press the button.''

"Please wait for a while." or the light of the indicator light.

” is displayed on the service side.

However, such push-button devices are ultimately intended for the visual sense, and blind people cannot even recognize their location, so they are barred from using them.

Therefore, in order for the blind person to use the push button, it is necessary to guide the blind person to the location of the push button.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic external view of a push button device according to the present invention, and 1 is a push button plate surface of a size that even a blind person can easily touch; It may have a structure in which the switching action is performed directly by pressing the surface, or a structure in which the switching action is performed with a so-called one-touch operation in combination with a piezoelectric element.

In addition, in order to use this push button for general pedestrian use, it is also possible to make the board surface transparent or semi-transparent to provide visual service using the indicator light mentioned earlier.

Reference numeral 2 denotes a front cover of the built-in speaker, which has a large number of holes on its surface, and a net-like cover 3 on the opening surface of the speaker inside.

4 is an outer box, and its general shape is not much different from the conventional one.

Figure 2 is a block diagram showing the outline of the traffic signal device configuration.
A is the block of the entire control device, B is the signal control section, C1,
C2 is an oscillation unit that generates sounds aimed at blind pedestrians in the first direction and the second direction, respectively.

Dl, D1'... are push button devices for the first direction, D2
D2'... is a pushbutton device for the second direction, and conventionally, the output signals of these pushbutton devices (hereinafter referred to as below) are input directly to the signal cylinder leg section B, and the signal control section B inputs the input signal. Vehicle signal lights E and pedestrian signal lights F were controlled accordingly.

In the case of this device, the oscillating part C1
Alternatively, the signal is inputted to the signal control unit B via C2.

FIG. 3 shows the internal circuits of the oscillation section (hereinafter referred to as C) and the push button device, and the connection relationship between the two.

The oscillator a in the oscillator C generates an oscillating sound to indicate the location of the push button to a blind person, for example, an intermittent sound such as "beep, beep, beep", and the oscillator a generates a signal from the pushbutton operation to the signal control section. An oscillating sound, such as a continuous sound such as "beep", is generated to indicate that it has been accepted by B.

The oscillator C also indicates that the pedestrian has been granted the right of way to cross the road requested by the pedestrian, that is, the vehicle signal light E on the side of the road that intersects with the crossing road indicates that the vehicle is stopped, and the pedestrian signal light F of the crossing road indicates that the pedestrian is proceeding. It generates an oscillating sound, such as a "bo" or a music sound, to indicate that the signal has been activated.

Furthermore, PBR is a push button reaction relay, PLR is a pilot lamp lighting relay, and PGR is a pedestrian progress indication reaction relay.

In addition to the pushbutton PB, which symbolizes the function of the board 1 in Fig. 1, the pushbutton device also houses a relay RY that assists the pushbutton, a speaker SP, a pilot lamp PL, etc., and their circuits. is connected to the oscillator C via a cable.

Next, the operational relationship between the circuits of the oscillator C and the push button device will be explained.

In the figure, ACI and AC2 indicate connection to an AC power source.

If the current required crosswalk is prohibited and the circuit of pushbutton PB is open, each relay shown in the figure has been restored, so oscillator a is relay PLR.

An output circuit is configured by the recovery contacts pIr and pgr of the PGR to drive the speaker SP and generate its oscillation sound outside the device.

The blind person can be guided by this generated sound and recognize the location of the push button device.

Next, when the pushbutton PB is pressed to configure the circuit of the relay RY, the relay RY operates, and the contact ry closes, thereby operating the relay PBR.

Due to the operation of relay PBR, a signal indicating that the push button has been operated is transmitted to signal control unit B via its contact pbr.

The signal control unit B returns a signal indicating acceptance of the operation signal and operates the pilot lamp lighting relay PLR.
The operation of the signal control section B during this period is the same as the conventional one.

The relay PLR lights up the pilot lamp PL, and its contact plr switches the circuit of the speaker SP to the output circuit of the oscillator, so a signal sound indicating acceptance of the push button operation is heard from the speaker SP, and the blind person can operate the push button himself. It can be recognized that the process was carried out normally.

Due to the control operation of the signal control unit B, the pedestrian signal light F
When the progress indicator is displayed, the reaction relay PGR operates and its contact pgr switches the circuit of the speaker SP to the output circuit of the oscillator C, and the sound generated by the speaker SP becomes the signal sound for permission to pass. Blind people can cross the crosswalk by following the signal.
