Data mining system and data mining method

Abstract

The invention discloses a data mining system. The system comprises a plurality of electronic control units (ECUs) and a data mining terminal, wherein the ECUs are connected by a controller area network (CAN) bus and form a CAN; and the data mining terminal is connected into the CAN by the CAN bus and used for mining data which meets conditions preset by a user from the CAN. The invention also discloses a data mining method. In the view of extracting objectively required data in practical application, configuration-based conditional acquisition and control can be performed inside and outside the CAN, and a wide data acquisition and control channel is opened for a closed CAN. The data mining method is particularly suitable for the remote data mining of the CAN communication network, and reliable means are provided for comprehensively monitoring vehicle states, scientifically making decision and responding in time.

Description

technical field [0001] The invention relates to a data mining system and a data mining method, in particular to a data mining system and a data mining method for remotely mining data in a CAN (Controller Area Network) communication network. Background technique [0002] With the increasing number of ECU (Electronic Control Unit) components in automobiles, functions such as data communication and fault diagnosis between ECUs are increasingly becoming the focus of the automotive industry and application technology. CAN is currently the most widely used serial bus system. The complexity and differences of its different link layer and application layer protocols are the biggest problem and obstacle for information exchange between the CAN network and the outside world. Due to the existence of corporate standards and technical differences among auto parts and vehicle manufacturers, the standardization and standardization research on CAN by standardization organizations and the CA...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problem that the existing technology cannot fundamentally solve the problem of data control interaction between the in-vehicle network system and the outside world, and the remote data acquisition system can only be aimed at a specific CAN network and a specific system and cannot be used universally. To solve the defects of data collection, provide a data mining system and data mining method that can realize data control interaction between the CAN network in the car and the outside world, and can realize general data collection
