Design Based on Multi-Channel Power Acquisition and Data Teletransmission System of MSP430 Simulating SPI Interface and CS5460A Communication

Abstract:

Real-time acquisition of multi-channel power and data teletransmission is the most frequent important problems in power system to be solved perfectly. SPI, a synchronous serial interface, can connect multiple microcontrollers and all kinds of input-output devices with SPI interface which send and receive independent. However, most microcontrollers usually only with a single SPI interface which seems powerless when it communicates with many chip in need of the way of SPI. This paper taking the three-phase power acquisition and data teletransmission design of power system as an example lays special stress on introducing a design method to well solve the above problems based on the realization of three-phase power collection through MSP430 simulating SPI interface communicating with multi-block CS5460A. The design is simple and low-cost. Moreover, it has a broad prospect of application in the fields of multi-channel data measurement and acquisition and teletransmission communication and so on.
