摘要: 采用GPRS业务平台实现数据采集和传输功能的数据采集终端.该平台集成了GPRS模块,ARM7微处理器和具有RS485接口的数据采集模块,移植嵌入式实时操作系统u/OS-Ⅱ以及小型TCP/IP协议栈uIP,构成一个对模拟量和数字量进行采集和传输的通用数据采集传输平台.该方法具有较高的性价比优势,可广泛运用于无线报警、环境、气象、交通等领域的数据采集和传输.

Abstract: We constructed a universal transmission platform collected and transmitted analog and digital quantity,which using GPRS business platform to collect and transmit data.The platform was integrated the GPRS model,ARM3 microprocessor and data collection model with RS485 interface,and using real-time operating system u/OS-Ⅱ and the stack uIP of TCP/IP protocol.This platform had high cost performance,it can be used widely in data collection of radio alarming,environment,weather ,traffic and so on.
