Abstract

The invention belongs to the technical field of vehicle engineering, and discloses a vehicle-mounted power supply monitoring device, which comprises a power supply detection controller module, an output control module, a fault indication module, an Internet of Things communication module and a cloud diagnosis server, wherein the power supply detection controller module detects detection parametersincluding working parameters of a vehicle-mounted power supply, environmental parameters of the vehicle-mounted power supply and running state parameters of a vehicle in real time and sends a vehicle-mounted power supply on-off control signal, the output control module is connected with the power supply monitoring controller module, the fault indication module is connected with the power supply detection controller module, the cloud diagnosis server is connected with the power supply detection controller module through the Internet of Things communication module, and the cloud diagnosis server performs data classification and combination on the detection data according to modes of different devices at the same time and the same device at different times, and performs outlier detection byadopting a clustering analysis method to determine the vehicle-mounted power supply with safety risks. The vehicle-mounted power supply monitoring device provided by the invention can realize high-timeliness fault detection.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle power supply monitoring device. Background technique [0002] Components such as automotive ECUs need a stable power supply. For this reason, the performance of the power supply is usually tested regularly, and the operation is relatively complicated; more importantly, the timeliness of such regular testing is poor, and the fault detection rate is low. SUMMARY OF THE INVENTION [0003] The present invention provides an on-board power supply monitoring device, which solves the technical problems of poor effectiveness and low fault detection rate in the prior art of on-board power supply state detection. [0004] In order to solve the above technical problems, the present invention provides a vehicle-mounted power supply monitoring device, including: a power supply detection controller module, an output control module, a fault indication module, an Internet ...
