Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention will be further described

[0039] host (see Figure 9 ): Interior rearview mirror with TFT display (one camera is installed inside).

[0040] This system uses braking signal, engine signal, reversing signal, and ignition switch to control the action of the system. These signals are all taken from the inside of the vehicle, and the signals are introduced to the relevant IO ports of the MCU (U6) through the connection ports J7 and J8 of the system (see Figure 6). U6 port function: AP: control port; PB0: running; PB1: reversing; PB2: VIDEO-IN; PB3: ignition switch; PC0: NC; PC1: browsing status; PC2: TFT switch; PDO: screen display control; PD1: LCD control; PD2: recording status detection; PD3: power status detection; PE: OSD control; PF0: DSP power control; PF1: prompt tone. Interface J7: 1: 12V-IN; 2: GROUND. Interface J8: 1: Brake; 2: Reverse; 3: Video-IN, 4: Ignition switch.

Abstract

A method for real-time recording of driving road conditions and a vehicle-mounted recorder thereof, wherein the method includes installing a camera for real-time monitoring of road conditions and a display screen for real-time display of road condition images at an appropriate position in the vehicle, and connecting brake signals, engine Signals, reversing signals, and ignition signals are input to the relevant ports of the MCU and control the system action; the control system includes MCU MCU, DSP digital signal processor, 2 Flash data memories, ROM program memory, RAM random access memory, Sensor image sensor (camera), USB interface and display.

Description

technical field [0001] The invention relates to a method and equipment for recording road conditions during driving of a motor vehicle, and mainly refers to a real-time recording method for driving road conditions and a vehicle-mounted recorder thereof. Background technique [0002] At present, the number of motor vehicles has increased sharply, and the accident rate has also risen sharply. There is a problem of how to accurately assign responsibilities during the accident handling process. If the accident process can be reproduced, the accurate assignment of responsibilities can be achieved. In order to achieve this purpose, there have been devices for recording traffic conditions, but due to technical and structural reasons, most of them have problems such as single function, unstable work, and high cost. Therefore, there is still a big gap from practical application. Contents of the invention [0003] The purpose of the present invention is to provide a real-time recor...
