基于DSP无线抄表系统设计

Design of Wireless Meter Reading System Based on DSP

为实现短距离无线抄表,以DSP2812为控制核心,采用先进的电能采集芯片CS5460A,对电压、电流、功率等进行测量和计算。同时采用无线收发模块nRF2401A对数据进行无线收发,在微处理器的控制下对数据进行处理后向上级系统发送,实现了采集终端和控制终端之间的短距离无线通信。采用DS1302作为系统时钟芯片,为系统采集电能提供了准确的时间信息。

This design takes DSP2812 as its controller, whose advantage is powerful function, low power- consumption, fast operation speed and so on. At the same time,it has a FLASH inside,whose capacity is 128k,which makes the structure of the system compact and flexible. This design uses DS1302 as its system clock chip,which provides the accurate time information. Moreover, advanced energy acquisition chip CS5460A may detect the voltage, current, power, electrical energy and so on. Simultaneously,it can transfer data through the wireless receive - and - send module nRF2401A. After dealt with data under the microprocessor control,the wireless receive - and - send module sends to the higher authority system, realizing the short distance wireless correspondence between the collection terminal and control terminal.
