Description

Mobile supercardioid speaker unit combined with radar

The present invention relates to a mobile super-directional speaker device coupled with a radar, and more specifically, outputting a guide message for slowing down and warning toward the vehicle as a voice message based on a result of measuring the real-time driving speed of a driving vehicle. Of course, it relates to a mobile super-directional speaker device combined with a radar that can induce slow and safe driving of a speeding vehicle by visualizing and displaying it through a display device.

In general, the main cause of large-scale traffic accidents is in most cases due to speeding. In this case, there are cases where the driver intentionally overspeeds, but there are cases where the driver does not actually recognize that the speed of the vehicle is in an overspeed state.

This phenomenon occurs because the driver's sense of speed gradually becomes dull while the vehicle is driving, and it is difficult for the driver to accurately grasp the speed of the vehicle without relying on the speedometer for the frequently changing vehicle speed.

In addition, since it is impossible for the driver to drive while continuously looking at the speedometer, there are cases in which the driver does not even recognize whether the vehicle is speeding in a state in which the braking distance required for the vehicle is not sufficiently secured.

In the past, there have been many studies to prevent the vehicle from falling into a speeding state in the driver's unconscious or slightly implied state. There are two methods for detecting the speed of the vehicle and for detecting the speed of the vehicle using a laser speed meter.

When the speed of the vehicle exceeds a certain reference speed, the speed control system automatically takes a picture of the license plate of the vehicle using a camera and imposes a predetermined fine or fine on the driver, thereby preventing the vehicle from speeding.

However, due to the nature of the system construction environment, the speed guidance system is often installed on roads without pedestrians, such as highways or arterial roads, and the method of burying the loop sensor on the road takes a lot of money to construct, so it is not economical. There is a disadvantage, and the laser speed meter has a problem that the speed of the vehicle cannot be accurately measured due to an obstacle in an area where there are many pedestrians.

Therefore, in order to solve this problem, the present inventors have developed a speed guidance system that is not obstructed by obstacles by allowing free movement of the installation location without incurring excessive construction costs such as burying the sensor on the road.

In order to solve the above problem, the present invention not only outputs a guide message for slow speed and warning toward the vehicle as a voice message, but also visualizes it through a display device based on the result of measuring the real-time driving speed of the vehicle in motion. An object of the present invention is to provide a mobile supercardioid speaker device coupled with a radar that can induce slow speed and safe driving of a speeding vehicle by displaying it.

The mobile supercardioid speaker device 100 coupled with the radar according to an embodiment of the present invention includes a body 110 provided to be movable, a body part 110 provided above the body part 110, and the speed of a driving vehicle. It is provided in the speed meter 120 and the body portion 120 for measuring the speed, and includes a speaker 130 that outputs a guide message to the vehicle based on the speed measurement result measured through the speed meter 120. can be characterized.

In an embodiment, the present invention may further include a display 140 provided on the upper side of the body 110 and outputting a real-time running speed of the vehicle toward the vehicle based on the speed measurement result.
