摘要
设计了一种基于低功耗的TMS320VC5409 DSP(数字信号处理器)和C8051F020单片机组成的数据采集传输系统,它能够采集、处理和通过无线移动网传送和接收数据。该系统以CPU单元为核心,主要由DSP、CPU、GSM(全球移动通信系统)3个单元组成,DSP单元用于数据处理,GSM单元用于数据传输。该系统具有体积小、便于携带、功耗低、可使用电池供电的特点,因而主要应用在要求移动数据采集传输的小型或便携仪器上。
A data collection and transfer system based on the low power consumption TMS320VC5409 DSP and C8051F020-signal micro-controller is introduced in this paper. The system has the ability of collecting, processing and transfering data with the mobile wireless net. The system which core is the CPU unit is compo^d of three units： DSP, CPU and GSM. The DSP unit is used for digital signal processing and GSM for data transmitting. The characteristics of the system are small size, portability, and low power consumption and can be powered by batteries, so it can be used in the small and portable devices.
