Problems solved by technology

The working principle of EMS is to read the driving data of the vehicle by connecting to the CAN bus of the vehicle engine, and monitor the user's driving behavior, vehicle status, fuel consumption and maintenance information in an all-round way, and this judgment depends entirely on the normal operation of the testing equipment , if there is an abnormality in the detection equipment, the read data will be inaccurate, and there is currently no mature EMS equipment monitoring system on the market

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] A kind of EMS terminal equipment fault remote diagnosis method based on multidimensional statistics, the steps of described diagnosis method are:

[0022] S1: Connect to the platform and accept the heartbeat of the EMS device; if there is no heartbeat on the day, consider that the EMS is not connected to the platform, end and mark it as a "not connected to the platform" device; if there is a heartbeat on the day, proceed to the next step of judgment;

Abstract

The invention relates to the technical field of fault monitoring of a vehicle-mounted device, in particular to a multi-dimensional-statistics-based remote fault diagnosis method for an EMS terminal device, thereby realizing functions of automatic monitoring and automatic diagnosis and the like. The effective guarantee is provided for monitoring the driving behavior of the driver by the device. According to the working state of a multi-dimensional-statistics-based remote fault diagnosis device for an EMS terminal device, whether the device has a fault or the connecting state of the device is determined based on a relationship between the vehicle mileage and the fuel consumption speed; and the determination logic and algorithm are continuously optimized during the post-stage implementation process; and the functions of automatic monitoring and automatic diagnosis of the device are realized. The effective guarantee is provided for monitoring the driving behavior of the driver by the device. Compared with the regular door-to-door checking and monitoring modes, the provided method has advantages of simple implementation, low cost, and high operability.

Description

technical field [0001] The invention relates to the technical field of on-vehicle equipment fault monitoring, in particular to a method for remote diagnosis of EMS terminal equipment faults based on multi-dimensional statistics. Background technique [0002] EMS is a control system composed of the core component electronic control unit (ECU) and a series of sensors and actuators. [0003] If the engine is the "heart" of the car, then EMS can be called the "heart" of the engine. The working principle of EMS is to read the driving data of the vehicle by connecting to the CAN bus of the vehicle engine, and monitor the user's driving behavior, vehicle status, fuel consumption and maintenance information in an all-round way, and this judgment depends entirely on the normal operation of the testing equipment , if there is an abnormality in the detection equipment, the read data will be inaccurate, and there is currently no mature EMS equipment monitoring system on the market.
