Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to traffic lights. More specifically, the present invention relates to a traffic signal that emits a pseudo-warning whistle sound and contributes to reducing traffic accidents.

[Background Art] In recent years, along with advances in automobiles and improvements in roads, the scale and severity of traffic accidents have been increasing. Traffic signals, which control the movement of cars, control the movement and stopping of cars by turning on blue, yellow, and red lights.

[Problems to be Solved by the Invention] By the way, car drivers are sensitive to the warning horns blown by traffic police officers, but they tend to ignore the displays on traffic lights.

Therefore, drivers drive carefully during traffic enforcement days, but on other days, they may ignore traffic lights. As a result, despite the efforts of traffic police officers, traffic accidents cannot be eliminated.

Therefore, the present invention provides information on the date and time of traffic enforcement.
The purpose of the present invention is to provide a traffic signal that alerts drivers by emitting a pseudo-warning whistle sound similar to the sound of a warning whistle sounded by a police officer when controlling traffic at an arbitrary date and time.

[Means for Solving the Problems] The traffic signal of the present invention includes a control device for controlling turning on and off of red lights, etc., and a traffic signal having at least yellow lights and red lights, the control device. sets at least one of the month and day for emitting a warning sound and the time for emitting a warning sound, and inputs a date and time setting device that outputs a date and time signal corresponding to the setting, and a date and time signal from the date and time setting device, During the period from the time corresponding to the date and time signal to the predetermined time, a pseudo warning whistle sound similar to the sound of a warning whistle sounded by a police officer when controlling traffic is generated a certain time after the yellow light is turned on. The present invention is characterized in that it includes a warning command section that outputs a warning sound command signal to be commanded, and a whistle sound generating section that emits the pseudo warning whistle sound when the warning sound command signal is input from the warning command section.

That is, the traffic signal of the present invention is characterized in that its control device includes a date and time setting device, a warning command section, and a whistle sound generating section.

The date and time setter is a device that sets at least one of the month and day for emitting the warning sound and the time for emitting the warning sound, and outputs a date and time signal in accordance with this setting. The date and time setting device may be configured to be controlled wirelessly or by wire from a central traffic control room.

Furthermore, it is desirable that the date and time set by the date and time setting device can be set to any desired date and time. What's even better is that this setting can be set either automatically or manually.

The warning command unit inputs the date and time signal from this date and time setting device, and a police officer will control traffic a certain amount of time after this yellow light is turned on between the time corresponding to this date and time signal and a predetermined time. This is a device that outputs a warning sound command signal that instructs the generation of a pseudo warning whistle sound similar to the sound of a warning whistle that sounds when a warning whistle is sounded.

The whistle sound generator is a device that emits the pseudo warning whistle sound when the warning command signal is manually inputted from the warning command unit.

There are no particular limitations on the mounting position, shape, etc. of elements other than those mentioned above, such as the date and time setting device, warning command section, and whistle generating section.

[Function] The traffic signal control device of the present invention has a date and time setting device, a warning command section, and a whistle sound generating section, in contrast to the conventional control device.

Use the date and time setting device to set at least one of the month and day the police officer will sound the warning sound, and the time the police officer will sound the warning sound.

The warning command unit manually inputs the date and time signal from this date and time setting device, and a police officer will control traffic a certain amount of time after this yellow light is turned on, from the time corresponding to this date and time signal until a predetermined time. A warning sound command signal is output that commands the generation of a pseudo warning whistle sound similar to the sound of a warning whistle sounded at the time of. When the warning sound command signal is input from the warning command section, the whistle sound generation section generates the pseudo warning whistle sound.

[Example] Hereinafter, the traffic signal of the present invention will be described in detail based on a specific example. The control device for this traffic signal has a date and time setting device, a warning command section, and a whistle generating section in addition to the conventional control device. Other equipment is the same as a conventional traffic signal.

Hereinafter, a control device which is a feature of the present invention will be explained using the block diagram shown in FIG.

This control device 10 includes a date and time setter 12, a warning command section 14,
, a whistling sound generating section 16, and a control section 18.

The date and time setter 12 is configured to be able to independently set the month, day, hour, and minute. The settings are made using four digital switches in the circuit. The output signal is input to the warning command unit 14, which will be described later, via an interface 171.

The main component of the warning command unit 14 is a microcomputer 17 that is activated according to a predetermined program.

The whistle generator 16 receives a signal from the warning command unit 14 via the interface 173 . It mainly consists of an amplifier 161 that outputs power to generate a pseudo-warning whistle sound based on this signal, and a speaker 163 that uses the power from the amplifier 161 to emit a pseudo-warning whistle sound.

The conventional control section 18 is used almost as is.

The above is the configuration of the control device IO used in this embodiment. Other equipment such as lights is used as is.

Next, the operation of this embodiment will be explained with reference to the flowchart of FIG. 2 showing a program executed by the microcomputer 17 (hereinafter referred to as CPU17).

The CPU 17 starts execution from step 100 when the start switch of the control device 10 is turned on.

Step! 00 is a step for setting initial conditions such as the time T for emitting the pseudo warning whistle after the time set by the date and time setter 12.

Step 102 is a step of reading the date and time when the pseudo-warning whistle sound is emitted. If it is determined that the date and time have been set, the process moves to the next step +04.

Step 104 is a step of determining whether the current time has reached the set time. Here, step 10
If it is determined that the time read in step 2 (set time) matches the current time, the process moves to the next step.

Step 106 is the step of determining whether the yellow light is currently lit. If it is determined that the yellow light is turned on, it is then determined in step lO8 whether a predetermined time ta has elapsed.

Here, the predetermined time ta is the time from when the yellow light is turned on, and after which the red light is turned on.

This [a] is a parameter determined depending on the traffic situation. In other words, a whistle sounds on behalf of a traffic police officer to alert drivers who attempt to enter an intersection despite the yellow lights being on.

Then, if it is determined that ta has been reached, step 11
0, a command to generate a pseudo warning whistle is issued to the whistle generator 16.

Then, the process moves to step 112. Here, the time for sounding the pseudo-warning whistle tf (tf; for example, 2 hours (if the start time is set at 19:00, it will be until 21:00).
) exceeds T. If it is determined that tf>T, the process jumps to step 102, and if not, the repeat routine of steps 106 to 112 is executed.

According to this embodiment, a date and time setter 12 composed of four digital switches is provided so that the month, day, hour, and minute can be set independently on the control device of a conventional traffic signal.
A warning command unit 14 by a microcomputer 17 as a main device, an amplifier 161 that outputs power to generate a pseudo warning whistle sound in response to a signal from the warning command unit 14, and this amplifier 5.
By mainly consisting of the whistle generating section 16 consisting of a speaker 163 that emits a pseudo warning whistle sound using electric power from the 161, and the control section I8, the pseudo warning whistle sound can be generated unattended at any date and time. . Therefore, by suddenly hearing this pseudo-warning whistle, drivers drive carefully and do not force their way into intersections, which can contribute to reducing traffic accidents. Furthermore, since a pseudo-warning whistle can be generated without the need for a traffic police officer to be stationed at all times, budget waste can be avoided without the need for extra traffic police officers.
