Vehicular video monitoring method

Abstract

The invention discloses a vehicular video monitoring method. According to a traditional vehicular video monitoring device, the power consumption is high, the endurance of a battery is difficult to improve, and the storage is low. According to the vehicular video monitoring method, a software platform comprises a console of Cortex-A8 carrying a Linux system, a USB camera, a USB memory, a pyroelectric detection module and a chargeable lithium ion battery. The pyroelectric detection module detects changing pyroelectric infrared signals generated by a moving object of a detection area on a passiveinfrared detector in a temperature change form. A master control circuit board analyzes and processes sensing signals received by the pyroelectric detection module. The USB camera starts collecting image and video data in a detection range when the infrared signals exist and transmits the data to the master control circuit board. The USB memory stores the collected data and can be fixed at any position with a plane. The method is applied to an infrared vehicular video monitoring device based on the Cortex-A8.

Description

Technical field: [0001] The invention relates to the field of intelligent control, in particular to a vehicle-mounted video monitoring method. Background technique: [0002] With the continuous improvement of people's living standards, cars have become an indispensable part of people's daily life; in recent years, people have paid more and more attention to the safety of cars when they are parked, so the driving recorder industry has developed by leaps and bounds ; Although the research on driving recorders has involved many aspects, the video storage space of the recorder is limited, and it is difficult to continue the battery life after parking; with the wide application of embedded technology in the electronics industry, the speed and low speed of the core chip The demand for power consumption is getting higher and higher, which has promoted the development of the chip industry; in recent years, the Linux system has developed rapidly in China, and has been widely used in ...
