Description

Technical Field

[0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a control circuit for realizing parking monitoring of a driving recorder through a six-axis gyroscope. Background Art

[0002] In the prior art, a driving recorder is an instrument that records images, sounds and other related information while a vehicle is driving. Currently, driving recorders are becoming more and more common. The device can be used to record the sound and video images while driving or parking, and can simultaneously record the time, location, and speed. When an accident occurs, it can provide evidence to the traffic department, thereby avoiding related shirking of responsibility and fraud, and providing reliable protection for vehicles and car owners.

[0003] At present, corresponding to the safety monitoring after parking, the general driving recorder adopts G-sensor for motion detection, which senses the acceleration of XYZ (three directions in three-dimensional space, front, back, left, right, up and down) axes. For example, when the vehicle is dragged, hit or other displacement behaviors, the driving recorder is turned on for monitoring, and the recording is stopped when there is no movement.

[0004] However, the existing G-sensor for parking monitoring can only detect acceleration in three directions in three-dimensional space, and cannot sense changes in the vehicle's angular velocity, such as rotation and tilt, and cannot accurately locate the collision position.

[0005] In addition, common terms in the prior art include:

[0006] ACC (Adaptive Cruise Control): The ignition signal voltage output by the controlled B+, the power supply when the key is in the ACC position, that is, the power supply to be disconnected during the engine starting process. This part of the electrical components generally carries a large load and does not need to work when the car is started. Generally, there is a cigarette lighter power supply, air conditioning power supply, and radio and television power supply.

[0007] Six-axis gyroscope: also known as six-axis motion sensor, its "six axes" are acceleration xyz axis and angular velocity xyz axis, that is, it can sense both angle changes and acceleration changes.

[0008] G-sensor: An acceleration sensor that detects changes in acceleration in the X, Y, and Z directions of space.

[0009] A driving recorder is an instrument that records relevant information such as images and sounds while a vehicle is traveling.

[0010] Parking monitoring means that when the vehicle is stationary and is subjected to a certain degree of vibration, it will automatically start recording. You can set the recording time and then stop again.

[0011] A DC-DC converter is a voltage converter that effectively outputs a fixed voltage after converting the input voltage. Generally, there are boost, buck, and buck-boost types, which have the characteristics of high conversion efficiency and large load current. An LDO converter, also known as a low dropout linear regulator, generates a regulated output voltage from the applied input voltage, and has the characteristics of low cost and low quiescent current.

[0012] A driving recorder is an instrument that records images, sounds and other related information while a vehicle is driving. Summary of the invention
