Description

CHCTEI dA OBSERVATIONS FOR CARS

This utility model relates to vehicles and is intended to monitor the traffic situation around the vehicle and record information about it.

A known system for observing the space around the car, which is not visible to the driver directly or through a mirror (DE, A1, 19801884). The image of the observed space is created using, for example, video cameras that are located in the headlights of the car, and is displayed to the driver on the monitors. The system also contains a microprocessor to which monitors and video cameras are connected and which allows you to edit the image and extract information from it.

A projection device for automobiles is known (DE, A1, 19638140), comprising two miniature cameras mounted externally on a car chassis, with the aid of which a traffic picture is taken, and a flat monitor installed inside the cabin, on which video signals from cameras are displayed as a combined image .

A known observation system for a car (WO, A2, 9638319), containing several devices that create images of the observed space around the car, and a dioplay system that forms a single picture, a1 synthesized based on the output of these devices and close to the general view of the terrain both from behind and in front of the car.

The main disadvantage of the known systems for observing the space around the car is that they provide viewing on a traffic monitor installed in the passenger compartment immediately at the time the car is in this place and do not allow

save information about it for later reproduction if necessary.

The basis of this utility model is the task of creating a monitoring system for cars, which ensures the storage of information about the traffic situation around the car, obtained in real time, and its reproduction at any time.

The problem is solved in that the surveillance system for cars, containing a group of miniature surveillance cameras installed on the vehicle to obtain images of the space observed around the vehicle, and a microphone for recording audio information, according to the utility model, further comprises a recording device and a video switch located in the vehicle for alternately connecting surveillance cameras to a recording device with subsequent playback on the indicator device ystve recorded information.

The recording device may be a video camera or VCR, or a digital audio / video recording system, and the indicator device may be, for example, a television.

The video switch contains a power supply connected to the vehicle’s on-board network, and a switch connected to the power supply, to the inputs of which surveillance cameras are connected, a control signal generator, the output of which is connected to the corresponding input of the switch, and a mixing block of video signals and control signals, the inputs of which are connected to the corresponding the outputs of the switch, the generator and the recording device, and its outputs to the corresponding outputs of the switch and the recording device.

The proposed system allows full control and fixing of the traffic situation around the car, which, for example, in case of an accident gives 100% independent evidence of what happened and,

consequently, it will facilitate the clarification of the circumstances of the accident.

In the future, the proposed utility model is illustrated by a specific example of its implementation and the accompanying drawing, which shows a structural block diagram of a surveillance system for cars.

A surveillance system for cars, according to a utility model, contains a group of miniature video cameras 1i ,, 1p surveillance and a microphone 2 that are installed on the car and connected to the video switch 3. The number of cameras 1i ,, 1p surveillance can be

different, but most appropriate to install on a car from two to eight cameras. The video switch 3 contains a power supply 4, which can be connected to the on-board network of the car and to which a recording device 5 located on the car can be connected. As a recording device 5, a video camera can be used, as shown in Fig., Or a VCR, or a digital audio / video recording system.

The video switch 3 also contains a switch 6 connected to the power supply unit 4, to the inputs of which the video cameras 1i ,, 1p are connected in the recording mode in the playback mode, the indicator devices 1i ,, 1p are connected to the switch 6, for example, TVs or

VCRs. In addition, a control signal generator 8 is connected to the power supply unit 4, one output of which is connected to the corresponding input of the switch 6, and a video / audio signal and control signal mixing unit 9 connected to the generator 8, the switch 6, and the recording device 5.

In accordance with the selected number of cameras 1i ,, 1p, s

with the help of which the observed space around the car is taken, they are connected in turn through the switch 6 to block 9. When the system is in recording mode, block 9 summarizes the signals from the cameras 1i ,, 1p and control signals.

formed in the generator 8, which are output for recording on a recording device 5, for example, a video camera, or a VCR, or a digital audio / video recording system.

If you need to view the recorded information about the traffic situation, the switch 6 operates in the playback mode, in which using it according to the control signals recorded

on a video tape, signals are output from one of the cameras 1i ,,

In to the corresponding output to which one of

indicator devices 7i ,, 7p, for example a TV, if required

only view information, or a VCR, if necessary, record information. In addition, using block 9, you can select the inclusion of any number of cameras or TVs (VCRs), select the time for the audible warning signal to end the tape in the video cassette, switch recording and playback modes

The power supply unit 4 connected to the vehicle’s on-board network, in addition to supplying the electronic circuitry of the video switch 3, makes it possible to power the recording video camera 5 regardless of the charging state of its own batteries by connecting the recording video camera's power line to unit 4
