Method and device for state detection and early warning of power cabin of electric vehicle

Abstract

The invention discloses a method and a device for state detection and early warning of a power cabin of an electric vehicle, and the method is characterized in that the method comprises the following steps: S100, powering and initializing a state detection and early warning device, and detecting and activating a communication interface; S200, sending a query instruction for the first time to query engine compartment parameters; S300, judging whether the parameters of the engine compartment are normal, if yes, executing the step S400, and if not, executing the step S600; S400, sending a query instruction by the state detection and early warning device by taking the query period as an interval, obtaining a current engine compartment parameter and outputting the engine compartment parameter to a corresponding indication unit; S500, judging whether the parameters of the engine compartment are normal, if yes, executing the step S400, and if not, executing the step S600; and S600, outputting abnormal engine compartment parameters by the state detection and early warning device to a corresponding abnormity indication unit and outputing a corresponding early warning signal, ending the detection, and quitting the process.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and relates to a multi-engine power cabin electric vehicle, in particular to a method and device for state detection and early warning of the electric vehicle power cabin. Background technique [0002] Electric vehicles include land electric vehicles and water electric vehicles, land electric vehicles include electric cars, etc., water electric vehicles include hydrofoil boats, etc. [0003] In the application of the prior art, for electric vehicles with multi-engine power cabins that integrate new energy and power, there is currently no method and device for detecting the working status of multi-engine power cabins, let alone multi-engine power A method and device for automatically sending out an early warning signal when some abnormality occurs in the cabin. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a method for state detec...
