Problems solved by technology

There are two disadvantages: 1. The diagnosis of the fault depends on experienced maintenance personnel; 2. When the maintenance personnel diagnose the fault, the fault has already occurred
However, this invention cannot monitor the working status of the automobile alternator in real time, and cannot provide a fault warning for the automobile alternator.

Embodiment Construction

[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] The invention provides a method for monitoring the health of an automobile alternator based on the data of the Internet of Vehicles, such as figure 1 As shown, the method includes the following steps:

[0027] Step 1, collect the operation data of the automobile alternator from the Internet of Vehicles, and divide the collected operation data in units of months according to the generation time of the operation data;

[0028] Step 2, calculating the number of effective acquisition times of the automobile alternator voltage from the collected operation data;

[0029] Step 3. Calculate the number of acquisitions of the unhealthy data of the automobile alternator voltage from the effective collection times. The unhealthy data of the automobile alternator voltage is data beyond the healthy voltage range. The data i...

Abstract

The invention discloses a method for monitoring the health of an automobile alternator based on the data of the Internet of Vehicles, which comprises the following steps: collecting the operation data of the automobile alternator from the Internet of Vehicles, and checking the collected operation data in units of months according to the generation time of the operation data. Divide the data; calculate the number of effective acquisitions of the automobile alternator voltage from the collected operating data; calculate the number of acquisitions of the unhealthy data of the automobile alternator voltage from the effective acquisition times, the data of the unhealthy automobile alternator voltage is beyond the healthy voltage range the data; calculate the collection probability of the unhealthy data of the automobile alternator voltage; judge whether the collection probability of the unhealthy data of the automobile alternator voltage exceeds the threshold value, and if so, determine that the health degree of the automobile alternator does not meet the standard. The invention can effectively monitor the working state of the automobile alternator in real time, and can give early warning to the failure of the automobile alternator.

Description

technical field [0001] The invention relates to the technical field of automobile alternators, in particular to a method for monitoring the health of automobile alternators based on Internet of Vehicles data. Background technique [0002] The automotive electrical system consists of a generator as an energy converter, a battery as an energy storage and electrical devices. As the requirements for vehicle comfort and safety continue to increase, the demands placed on the performance of electrical systems also increase significantly. More and more automotive components are electrified, such as electric seat adjustment, electric parking brake, electric steering assist, etc. [0003] The car alternator is an important part of the car's electrical system. The car needs to charge the battery through the alternator, and provide power to the ignition device, fuel injection device, electronic control unit, lighting and other electrical components. Therefore, the power of the genera...
