FlexRay Bus-Based Integrated Technology on Airborne Utility Management Computer

In order to improve the reliability of traditional utility management computer, and to meet those requirements of small, low and light design, this paper has proposed a highly reliable and modularized systematic architecture based on FlexRay bus. In this paper, the software and the hardware scheme on universal FlexRay bus communication unit based on FPGA and MFR4310 has been planned; the hardware and the software design of CPU module and interface functional module has been completed; the testing environment for utility management computer has been constructed. The test results have shown that the FlexRay bus-based new utility management computer can greatly improve the reliability and the temporal certainty of data communication among functional modules. It has reduced the volume and the weight of this product, and provided an effective solution to improve the function and performance of the utility management computer.
