Description

Early syren of overspeed car use supervision traveling camera}

The present invention relates to a camera early warning device for a mobile speeding vehicle. In particular, the driver unintentionally speeds up and warns the driver of the vehicle at a speed exceeding the specified speed, thereby inducing the speed below the specified speed. The present invention relates to an early warning device of a mobile speed camera for speeding a vehicle to prevent accidental safety accidents such as a collision with a subsequent vehicle following sudden sudden braking based on a mobile camera installed for speeding a vehicle. .

In general, it is preferable that vehicles traveling on various roads such as highways or national highways travel at economic speeds or speed limit speed ranges, but they may drive at speeds without knowing themselves depending on the driver's inclination or unconscious psychological state. Looking at the camera often caused sudden accidents, such as sudden sudden braking or change to a very dangerous large accident.

In particular, such a traffic accident is caused by the damage to many people together with it, and also causes a lot of national economic losses. In particular, the damage is more serious in our country where the traffic accident rate is much higher than other developed countries. to be.

Therefore, it minimizes large collisions or safety accidents caused by sudden braking or changing lanes by the speed camera, and easily obtains geographic information from the vehicle to provide various information such as the location and distance of the destination to be moved. GPS (Global Positioning System / Satellite Positioning System) is installed in the vehicle to obtain the current situation.

The satellite positioning system (GPS) is briefly described as follows.

The satellite positioning system was developed in the early 1970s by the US Department of Defense for $ 6 billion for military purposes to measure the position of objects on Earth, using GPS to obtain location and time. 24 GPS satellites (actually 27, including 3 supplementary satellites) continue to rotate the Earth's atmosphere in different orbits. This is to obtain four or more satellite signals at any time on earth. In order to measure position, signals must be received from at least four satellites simultaneously. Of course, if you receive signals from more satellites, you can get more accurate position values. The GPS receiver has 4 channels and 8 channels according to the number of satellite signals processed simultaneously.

In addition, the satellite positioning system (GPS) has a positioning data of 50 m or less for a PPS (Precision Positioning Service) used for military purposes, and a SPS (Standard Positioning Service) of 200 m or less provided to a civilian. Has an error range. The civil service is deliberately reduced in accuracy. As a method of correcting such an error, DGPS (Differential GPS), which reflects data corrected by using a difference between a coordinate value of a specific position and a measured value therein, is used. By using DGPS, the margin of error can be reduced to within 5 m. Recently, DARC system, which provides DGPS correction data through FM broadcasting, is also introduced in Korea. Another position measuring system is the Soviet GLONASS, and a method has recently been developed to reduce the error range by using GPS and GLONASS signals simultaneously.

The GPS system is installed in airplanes, ships, vehicles, etc., and the GPS is used together with the electronic maps (GIS) for navigation devices.It is also used to determine the location of moving objects such as people and vehicles. Since the information on the location of the camera for fixing the vehicle fixedly on various roads is informed, a lot of vehicles are installed and used so that the driver of the vehicle moving to the destination can receive such information and move to the destination more safely and conveniently. to be.

However, since the GPS system transmits information on the coordinates of the fixed object to the vehicle, the position of the mobile control camera is impossible to identify. Therefore, the driver of an unconscious psychological state is overspeed without knowing himself. In the case of driving, large accidents were frequently caused by seeing a mobile speed camera and causing extremely dangerous crash accidents such as sudden braking or changing lanes.

Fixed unmanned speed intermittent cameras installed on various roads are excellent in terms of performance, but speed measurement uses expensive fixed radar / loop coil method, which makes them impossible to move and loses utility to drivers who recognize the installation location. There are drawbacks, and the cost of facility is high due to the high product cost, so it is relatively inexpensive and easy to install and move. Therefore, a fixed speed camera is not installed in the road section. It is a situation where an overspeed vehicle is being controlled more than speed.

Here, the mobile speeding camera has a high accuracy, efficiency and portability, but can measure about 50 to 80 m.

Therefore, in recent years, a vehicle speed regulating device has been used in which a speed of light emitted from a laser or infrared light is reflected from a traveling vehicle to count speed is determined to determine whether the vehicle is overspeed.

Therefore, the object of the present invention is to warn the driver of the vehicle at an early speed for the driver's unconscious speeding to induce it to decelerate the speed below the specified speed to warn the driver, the mobile camera installed for the speeding of the vehicle It is to provide an early warning device for a mobile camera for a speeding vehicle that can prevent accidental safety accidents such as a collision with a subsequent vehicle that has been followed by sudden sudden braking.
