| Abstract: | As to the weak antijamming capability and the single-function of traditional electricity acquisition and processing system,a three-phase electricity acquisition system which is imposed by special chip CS5460A is presented.CS5460A and P89LPC932 are used for electric gathering and data processing respectively.It can transmit real-time measured values of various electric quantities from Serial Peripheral Interface(SPI).The circuit diagram and the software which is used to simulate SPI communication are given.By using Ethernet communication,it can realize power centralized management on upper computer and remote data transmission. |
