Research of power multi-parameter monitoring system based on dual CPU

A power multi-parameter monitoring system based on DSP and MCU is presented in this paper.Its main controller is MSP430F149and TMS320VC5402,using CPLD for the second controller.All kinds of status messages of electric network are acquired,saved and sent to the controller.Then,they are analyzed in time to evaluate and monitor HV electric network.Its software and hardware design scheme,key technologies and implementation are presented also.It has been proved by tests that the system is good at practice in stability and data monitoring,and will be of great appliced value.
