分布式电法采集站控制系统的设计与实现

摘要

针对分布式电法勘探的特点，提出了一种以新一代高性能低功耗的 ARM 处理器AT91SAM9G45为核心的分布式电法采集站控制系统的设计方案，系统包括128 MB 的 DDR2 SDRAM 内存系统、256 MB Nand Flash 存储块以及 CF Card 接口，同时支持 ZigBee 模块、WiFi模块和蓝牙模块用于无线控制和数据传输。通过移植内核和驱动程序，并由 SSC 接口成功地接收到来自 DSP 的采集数据，进而验证控制系统功能的可信性，从而为分布式电法采集站的控制系统，提供了一种可行的设计方案。%According to the characteristics of the distributed electrical prospecting,a solution of control system design is proposed based on high-performance low-power ARM9 chip AT91SAM9G45 in distributed electrical method in this paper. The system consists of 128 MB of DDR2 SDRAM memory system,256 MB Nand Flash storage blocks,CF Card interface,and support the ZigBee module,WiFi module and Bluetooth module for wireless control and data transmission.By porting the ker-nel and drivers,successfully received the data from DSP by SSC interface so that it can verify the credibility of the control sys-tem,thereby provides a feasible designing scheme for control system in distributed acquisition system.
