Abstract: After introduced some applications of embedded technology, one design of embedded electric power on-line monitoring system for measuring three-phase electric parameter was discussed. This design adopts multi-CPU embedded system policy and master-slave CPU hardware structure, which was developed that 89C52 microcontroller (slave CPU) played a role of AC sampling and S3C4510B (master CPU) took responsibility for calculating electric parameter, network communication and system management. Besides described the system structure, the paper also analyzed the module design of system software in details. The system was proved working ebucffectively and reliably in application, which satisfied the request that the embedded monitoring system need, made the data processing easily and directly.
