A power data transmission method between dual processors based on SPI communication

The computing power requirements of power equipment are gradually increasing with the development of the IoT (Internet of Things), and more and more power equipment adopts a dual processor architecture design. Reliable transmission of power data between dual processors is a research direction. This paper provides a reliable communication method between dual processors in power equipment, based on SPI communication bus, which abstracts the communication process into multi-layer transmission of communication layer and application data layer. Reliable communication of various types of complex power data has been achieved without adding response lines or response interfaces. This method can be widely applied to various types of power equipment. The results show that this method can achieve stable and reliable data transmission between dual processors of power equipment.
