A method and system for implementing a low-power consumption sentinel mode based on an MTK cockpit platform

By using the SCP coprocessor on the MTK cockpit platform to independently perform sensor and video data processing in the AP's sleep state, and only wake up the AP in case of an anomaly, the problem of high power consumption in the vehicle-mounted sentry mode is solved, achieving a balance between low-power operation and functional integrity.

AI Technical Summary

Technical Problem

The existing vehicle-mounted sentry mode cannot effectively reduce power consumption while ensuring the ability to detect abnormal events and the integrity of evidence collection. In particular, power consumption is significant in parked scenarios, which affects the vehicle's range.

Method used

Using the MTK cockpit platform, the system coprocessor SCP independently performs sensor data acquisition, video processing, and artificial intelligence detection after the application processor (AP) enters the STR sleep state. When an anomaly is detected, the AP is woken up to perform video data processing, thus achieving a low-power mode.

Benefits of technology

While ensuring the detection capabilities and evidence integrity of the sentinel mode, the overall power consumption in parking scenarios is significantly reduced, improving the system's practicality and response efficiency, and ensuring reliable identification and complete recording of abnormal events.

Abstract

The application provides a method and system for realizing a low-power consumption sentry mode based on an MTK cockpit platform, and relates to the technical field of vehicle-mounted electronics. The method comprises the following steps: obtaining a sentry mode starting signal; a system coprocessor SCP receives a sentry mode starting instruction and a multi-path camera control instruction sent by an application processor AP, and triggers the application processor AP to enter an STR sleep state; the system coprocessor SCP executes a sentry mode processing flow in a low-power consumption mode, detects an exception, and wakes up the application processor AP to resume operation when the exception is detected. The application processor AP reads video data corresponding to a time period from a circular buffer area, generates an exception event video, and executes a preset processing. The application is used in the process of realizing a low-power consumption sentry mode based on an MTK cockpit platform, and solves the technical problem that the prior art cannot reduce power consumption during sentry mode operation under the premise of ensuring the detection capability of the sentry mode on an exception event and the integrity of evidence.
