Design and Implementation of RTU Remote Measurement Unit Based on Dual-CPU

The paper introduced a product that designed and implemented for the GEA-2000A remote measurement unit. It introduced the designing idea of RTU remote measurement unit based on dual-CPU, described aspects of hardware structure and software design by detailed data. It emphatically analyzed the problem of data matching of DRAM in data acquisition and processing system based on multi-CPU. It put forward a new matching method for dual-CPU in writing and reading DRAM. The experiment result demonstrated that using dual-CPU mode can improve processing speed and reduce time of data transmission.
