Problems solved by technology

Among them, the thermal power consumption of the LED is usually very large, and the power consumption of the imaging chip is relatively small. The maximum allowable temperature (Tj) of the LED is also higher than the maximum temperature (Tj) allowed by the imaging chip, but the thermal deformation of the LED has little effect on its function. Large, and the thermal deformation of the imaging chip will affect the clarity of the image
[0004] The response of the existing control system is relatively slow, and the participation of the LED heat dissipation system in the heat dissipation is not enough, which will also cause the temperature on the imaging chip of the control system to be too high, which will affect the clear imaging of the imaging chip

Abstract

The invention discloses an intelligent vehicle-mounted monitoring system with an intelligent power supply control circuit. The system comprises a plurality of panoramic camera systems, a front radar probe installed on the front side of an automobile, a rear radar probe installed on the rear side of the automobile, a vehicle-mounted host system, a panoramic radar processing system and a vehicle-mounted displayer. A brand new circuit design is adopted for the control system, meanwhile, the control system and the LED protection device are arranged in a separated mode, the LED lamp panel is arranged on the front shell, the control system is arranged on the rear protection device, and an imaging chip of the control system is arranged on the chip board, so that two heat sources of an LED and the imaging chip are separated, heat generated by the LED is prevented from being transmitted to the imaging chip. Meanwhile, the temperature of the LED and the imaging chip can be conveniently controlled in a partitioned manner.

Description

technical field [0001] The invention relates to the field of vehicle-mounted monitoring systems, in particular to an intelligent vehicle-mounted monitoring system with an intelligent power supply control circuit. Background technique [0002] With the continuous development of society, automobiles have gradually entered people's lives and become an indispensable part, and the relationship between people and automobiles has become closer and closer. Imbalance, objectively appear the phenomenon of declining driving skills, there is a great safety hazard, for this reason, the market has appeared on the market to monitor fatigue driving monitoring systems such as driver behavior and facial features. Among them, DMS (Driver Monitoring System, driver monitoring system) captures the driver's facial features through the lens and infrared light source, accurately marks the specific location, and analyzes the driver's distraction while driving according to changes in pupils, face, and...
