Design and Realization of a CAN Network Development and Analysis Tool

Abstract

With the large-scale promotion and application of CAN bus in automotive electronics, a set software tool supporting the development, analysis and test of CAN bus network is required for the design of CAN network and single automotive electronic unit. Since the CAN bus development and analysis tool adopted by the buyer is quite expensive and it should be bonded to specific CAN card, it is not applicable for parallel development. The team of the author realized a low-cost CAN network development and analysis tool with Java and JNI by taking Eclipse as the development platform. The tool mainly includes two parts, namely the networking protocol design tool and bus monitoring tool. The former realizes the design of signal matrix, provides several views for the network signal, and generates XML signal matrix as the interface of bus monitoring tool; while the latter realizes the control and interface of ordinary CAN card, which will carry out the real-time monitor of bus data and provide several views of the data for further analysis through connecting CAN card to the CAN bus network.
