Research on Application of EPA Bus Technology in Embedded System

摘要

Aiming at the problems of low data throughput, poor information security, difficulty in compatibility of heterogeneous networks, and inability to be fully autonomous and controllable of 1553B/CAN bus, which are widely used in current embedded systems. Based on China’s industrial control bus EPA, which has completely independent intellectual property rights, a full EPA-based “one network to the end” electrical system data transmission program is proposed. It broke through the key technologies of multi-network cascade, multiple redundancy, and dynamic topology changes faced by EPA applied to embedded systems, and built an integrated embedded system bus simulation test platform. The test results show that the EPA bus network can meet the requirements of the embedded system, can significantly improve the transmission performance, real-time performance, reliability and safety of the embedded system, and is completely autonomous and controllable, which is helpful to the improvement of the embedded system.
