Parking monitoring method based on gravity sensor and GPS (Global Positioning System)

Abstract

The invention provides a parking monitoring method based on gravity sensor and a GPS (Global Positioning System). The vehicle state can be automatically identified without external connection of a detection line. When a vehicle encounters the dangerous situations of vibration, collision and the like, picture-taking and video-recording functions can be woken up automatically, and photos and videos are transmitted to a client, so that a user can comprehend the vehicle state in the first time. After the vehicle becomes safe, a guard monitoring state is entered automatically, and functional modules such as a camera module are shut down till an automobile data recorder is woken up, so that sufficient storage for saving photo and video files is ensured when the vehicle is in danger; coverage of valid files is avoided; the power consumption is lowered to the maximum extent; the problem of electricity consumption caused by long parking monitoring time is solved; and the parking monitoring time is prolonged greatly.

Description

technical field [0001] The invention relates to the field of automobile communication equipment, more specifically, to a parking monitoring method based on gravity sensors and GPS. Background technique [0002] The driving recorder can be regarded as the black box used by the car. By starting the engine, the video recording function will be turned on immediately, and the video and sound of the vehicle will be recorded through the high-definition lens. When an accident occurs, evidence will be provided immediately to protect the driver's self. right. After the driving recorder is installed, it can record the video image and sound of the whole process of the car driving. The internal sensor can set the sensitivity of the impact force. When the external impact force is greater than the set value, the on-site data of the impact force will be recorded. , which can provide evidence for traffic accidents. Driving recorders include single recorder, front and rear double recorder, ...

AI Technical Summary

Problems solved by technology

However, to achieve long-term parking monitoring, there must be enough storage space to save audio and video files, and there must be enough power to maintain the long-term power consumption of the driving recorder

However, the storage space of the driving recorder is very limited. Generally, the previously recorded video will be overwritten after a few hours. After the engine is turned off, the battery of the vehicle is not allowed to consume too much power, so as to avoid affecting the normal start of the vehicle next time, so , the existing portable driving recorder cannot perform long-term parking monitoring
