Abstract

PURPOSE:To synthesize a variety of communications and information processing systems so as to simplify an output part and to facilitate monitoring by employing the signal switching device of a microcomputer control. CONSTITUTION:Normally, a television tuner 7 and a car audio device 9 are manually switched to output a signal to a crystal liquid display 5 and a sound output device 6. After the output obtained by A/D-converting an output from a telephone set 8 or a camera 1 inputs an offering signal 31 to the microcomputer 4, it interrupts a switching control signal 41, and displays the output of the telephone set 8 on the sound output device 6 and that of the camera 1 on the crystal liquid display 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an in-vehicle communication information processing system including a TV camera and a video monitor.

(Prior Art) Conventionally, in-vehicle TV systems include at least one set of small T.
It consists of a V-camera and a small video monitor, and has been developed and put into practical use specifically for purposes such as monitoring the rear of large buses and the like when reversing. On the other hand, a small TV receiver is installed inside the vehicle to receive TV broadcasts, and recently, a drive computer (microcomputer) and a small TV monitor are combined to create a road map of the destination. etc,
Even systems that display various types of information have been developed. However, these are all independent systems, and each must be equipped with a small video monitor (or TV receiver) for output.

On the other hand, various communication systems such as car audio, personal wireless, and car telephones have been put into practical use, but each of these must also be equipped with an individual audio output device, and is completely separate and independent from the above systems. / stem, each device required a large number of display output devices,
Another drawback is that it is difficult to monitor the driver.

(Object of the Invention) An object of the present invention is to eliminate such drawbacks, integrate various communication and information processing systems, and simplify the output section by having a microcomputer and a signal switch controlled by the microcomputer Vc. A table that makes monitoring easy! I
Our purpose is to provide information processing and U-systems.

(Structure of the Invention) The in-vehicle communication information processing system of the present invention includes an information output section consisting of a set of video monitor and audio output device, a television camera, and a television broadcaster.

an information input section including a car phone and car audio;
A micro combinator which processes information input from the television camera or the car telephone for vehicle operation, and switches all inputs from the micro combinator and the information input section according to instructions from the microcomputer. and a signal switcher for outputting to the information output section.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, 1 is a solid-state imaging camera such as a CCD, 2 is a signal switch, 3 is an A/L converter, 4 is a microcomputer, 5 is a liquid crystal display, and 6 is an audio output such as a speaker. 7 is a TV tuner, 8 is a car phone, 9 is a car audio system, 10 is an input terminal, and 11 is an output terminal. The CDD cap imaging camera 1 is connected to a signal switch 2 and an A/D converter 3.
3 converters are connected to 4 microcontrollers. The analog video signal 21 is output from the CCD solid-state image camera 1, A/D converted by the A/D converter 3, and converted into a digital signal 31 which is input to the microco/4. Signal switching 4
On the output side r-1 of 2, the video signal 51 is sent to the liquid crystal display 5.
, and an audio signal 52 is connected to the audio output device 6.

On the other hand, there is a TV channel at the input end of the signal switch 2.
! -7, car phone 8. The signal output terminals of the car audio 9 and the microcomputer 4 are connected, and also connected to the car phone 8#'i A/D converter 3, and the received signal 2
2 to A/Df+? and output to microcomputer 4.

Further, the microcomputer 4 is connected to both input terminals 10, and various information 32 regarding vehicle operation is manually inputted thereto. Furthermore, the signal switching from the Iil control signal output terminal of the microcomputer 4? A switch control number 15 41 to S2 is output, and a control signal 42 to the vehicle operating system is output to the output terminal 11.

Next, the operation of this embodiment will be explained.

Normally, the signal switch 20 is manually operated to switch to the TV tuner 7 or car audio 9, and output the video signal 51 and audio signal 52 to the gift display 5 or the audio output device 6. Father, -f icon 4 has input terminal 10
Various information 32 regarding vehicle operation F is always inputted from the terminal 11, and a control signal 42 to the vehicle operation device is outputted to the output terminal 11.

Furthermore, if the signal switch 2 is manually switched to the microcomputer 4 side, the microcomputer 4 outputs arbitrary information such as a road map, fuel consumption calculation, etc. to the liquid crystal display 5 or the audio output device 6. However, here, the profit signal 3 is sent to the microcomputer 4.
1 or Fi32 is input, the microcomputer 4 interrupts the signal cutter M unit 2 with a switch control signal 41, and outputs an input signal corresponding to this interrupt input signal to the liquid crystal display 5 or the audio output device 6. Output. That is, when the received signal 22 from the car phone 8 is input, this is displayed on the liquid crystal display 5 and the audio output device 6 is made to output the audio of the phone.

Also, when the To vehicle retreats, the retreat signal 32 enters 411, and the CC
D The video signal 21 of the solid-state imaging camera 1 is outputted to the liquid crystal display 5 via the signal switch 2.

At the same time, the video signal is inputted to the microcomputer 4 via the 21-digit A/D converter 3, and the image can be processed.

Therefore, if there is an electrically harmful object behind the vehicle, the microcomputer 4 can determine this and output a warning signal 52 to the audio device 6 via the signal switch 2. However, if the interrupt signal 31 or 32 is subsequently removed, the original state before the interrupt is restored.

In addition, in this production example, CCDC is used as a 9゛v camera l.
Although a D solid-state imaging camera is used, it goes without saying that other solid-state imaging cameras or conventional Nadatsuka Haru-type cameras may be used, or a digital camera with a built-in A/T converter may be used. My father used a liquid crystal display 5 as a video monitor, but it is also possible to use a conventional CRT display, and it is clear that even if a car phone becomes a TV, it can be processed using exactly the same concept. . or.

The same applies when there are a plurality of the above-mentioned devices as input devices, or when other input devices are connected, but the explanation will be omitted here.

(Effects of the Invention) According to the present invention, as explained above, by integrating various communication and information processing systems, various information can be easily transmitted.
A comprehensive in-vehicle communication information processing system capable of handling C-channel communication is obtained.
