Abstract

The invention discloses an engine state monitoring method based on an automobile voltage. The method comprises the following steps of: enabling a control module to read a power supply voltage of an automobile through an external analog to digital converter every second; storing the read power supply voltage into a circulating linked list according to a time sequence; calculating and recording an ignition voltage and a flame-out voltage of an automobile engine by using a memory algorithm; and judging the current state of the automobile engine by using the ignition voltage, the flame-out voltage and the current power supply voltage of the automobile engine. Through the adoption of the engine state monitoring method based on the automobile voltage, disclosed by the invention, an additional peripheral device is not needed, the judging accuracy is made accurate, and the design and use cost is also reduced; in addition, supports from automobile manufacturers or manufacturer models are not needed, so that the generality of the engine state monitoring method based on the automobile voltage is satisfied.

Description

technical field [0001] The invention relates to an automobile engine state detection and vehicle networking technology, in particular to an engine state monitoring method based on automobile voltage. Background technique [0002] Nowadays, the rapid development of Internet of Vehicles technology has brought about the blowout development of on-board electronic equipment, such as on-board communication modules, on-board radio frequency electronic tags, etc. These products have one thing in common, they all need the power supply of the car power system, and they Generally, there is a large amount of data processing and transmission during the operation of the car. And because when the car engine stops working, the car power is provided by the car battery. If the on-board electronic equipment is always in a normal working state, it will consume a lot of car battery, which will cause the car to fail to start normally next time. The current solution is generally to let the on-boa...
