CONSTITUTION:Two infrared sensors 21 and 22 are provided at a constant interval and when a vehicle reacts to the 1st infrared sensor 21, the timer measuring instrument 23 operates to measure the time up to the reaction to the 2nd infrared sensor 22; and its speed is calculated from the time and the installation distance between the infrared sensors and when the calculated speed is faster than a set speed, a telecamera 24 and the magnetic recording device 25 are put in operation to perform constant recording. Consequently, the records can be controlled concentrically, malfunction is eliminated, and the secure evidence is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a speed control device installed and used on a road.

BACKGROUND OF THE INVENTION In recent years, the number of traffic accidents caused by speeding has increased, and videotapes have come to be accepted as evidence in court cases, increasing the need for speeding enforcement devices that use videotapes. A conventional speeding enforcement device will be explained below.

FIG. 3 is a block diagram showing the system configuration of a conventional speeding enforcement device. As shown in the figure, the time measuring device 3 uses data from the distance measuring device 31 and the time measuring device 32.
A control device 36, which is a means for controlling 2, a camera 33, and a light emitting device 34, obtains data from a distance measuring device 31 and a time measuring device 32.
3 and the light emitting device 34 so as to output a control signal.

The operation of the conventional speeding enforcement device configured as described above will be explained below with reference to FIGS. 3 and 4.

First, as shown in FIG. 4, when a car 42 approaches, the radio waves sent out from the distance measuring device 31 of the speeding enforcement system @ 41 hit the car 42 and are reflected back to the distance measuring device 31. 42, and after a certain period of time has elapsed using the time measuring device 32, the distance from the vehicle 42 is measured again using the distance measuring device 31, and the speed is calculated from this data. If this speed exceeds the set speed, it is considered a speeding violation. The camera 33 and light emitting device 34 are operated to take a photograph of the automobile 42.

Problems to be Solved by the Invention However, the above-mentioned conventional speeding enforcement devices malfunction when it is raining because the radio waves reflect off the rain. Because they emit radio waves, they detect the radio waves in reverse and slow down only to pass through areas with speed enforcement devices, making it impossible to stop them. The generator only emits light for a moment, so if you can memorize the location and slow down to pass only that area, you will not be able to control it. Since it is a still photo and may malfunction in rainy weather, even if the speeding violation is not acknowledged by the offender, it will not be conclusive evidence that he or she was speeding and the system will not be cracked down.

Since the film in the camera cannot be inserted without going to the location where the equipment is installed, there is no way to know if the film has run out, and enforcement is not carried out while the film is running out. It had the following drawbacks.

The present invention solves the above-mentioned conventional problems, and is a speeding enforcement device that can centrally manage records, eliminate malfunctions, and leave reliable evidence of overspeeding without being noticed by the driver. The purpose is to provide

Means for Solving the Problems To achieve this object, the speeding enforcement device of the present invention includes a magnetic recording/reproducing device, a television camera, a time measuring device, an infrared sensor, a lighting device, and data from the time measuring device and the infrared sensor. It has a configuration of means for controlling a magnetic recording/reproducing device and a time measuring device.

Function The present invention uses two infrared sensors arranged at regular intervals with the above-mentioned configuration. When the υ car reacts to the first infrared sensor, the time measuring device operates until it reacts to the second infrared sensor. The speed is calculated using this time and the installation distance of the infrared sensor, and if it is faster than the set speed, the television camera and magnetic recording device are operated to record a certain amount of data.

EXAMPLE Hereinafter, a speed violation enforcement device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of a speeding enforcement device according to an embodiment of the present invention. As shown in the figure, a control device 16 is a means for controlling the magnetic recording/reproducing device 15 and the time measuring device 13 using data from the time measuring device 13 and the infrared sensor 11.12. It is connected to obtain data and to output control signals to the time measuring device 13 and magnetic recording/reproducing device 15. TV camera 14
is connected to the magnetic recording/reproducing device 16 so as to output a video signal. The magnetic recording/reproducing device 15 is a monitor 18
is connected to output the video signal. The lighting device 17 is the same as a normal street light and turns on automatically depending on the surrounding brightness.

The operation of the speeding enforcement device according to an embodiment of the present invention constructed as described above will be explained below with reference to FIGS. 1 and 2.

First, when the automobile 29 reacts to the infrared sensor in the speed control device arranged as shown in FIG. 2, the time measuring device 26 operates to measure the time until the infrared sensor 22 reacts. The speed is calculated based on the measured time and the installation distance of the infrared sensors 21 and 22, and if this speed exceeds the set speed, a recording command is sent to the magnetic recording device 25 to record the photograph of the car 29 for a certain period of time. will be carried out. When the amount of light is insufficient, such as at night, it is possible to take pictures using lighting devices such as street lamps, so that the driver will not notice.

In addition, it is possible to search for the violator by viewing the recorded tape on the monitor 28 at a later date, and by recording the time and lighting equipment 2a installed at regular intervals as a reference position on this video, υ Since the time it takes to pass a certain distance is known, there are no mistakes and only those who actually violate the law can be arrested. Also, since the sensor emits infrared light directly to the side, reverse detection is not possible. In addition, a magnetic recording/reproducing device 25 and a monitor 28
It can be installed at traffic control centers, police stations, etc., and the tape can be replaced immediately. This makes it impossible for drivers to always drive faster than the legal speed limit because they do not know where speed enforcement devices are located.

Furthermore, the image from the television camera 24 can be viewed directly on the monitor 28, making it possible to monitor the traffic situation on the road.

Effects of the Invention As is clear from the embodiments described above, it is possible to realize an excellent speed enforcement device that enables centralized record management, eliminates malfunctions, and leaves reliable evidence of overspeeding without being noticed by the driver. It is something.
