摘要
研究了基于ARM9和GPRS的实时性数据传输系统的设计方法。该系统在32位ARM微处理器S3C2440A中移植具有实时响应性的Linux2.6操作系统,并且采用直接对Linux内核进行修改以实现中断线程化的方式进一步提高实时响应性,进而提高系统的数据处理和传输速率。采用GPRS模块MC35传输数据,并利用宽带GPRS与Internet的无缝连接实现远程监控。测试表明该系统可以实现嵌入式终端数据的实时采集和传输。
A method of real-time data transmission system based on GPRS and ARM9 was studied.Operating system Linux2.6 with real-time responsiveness is transplanted on 32-bit ARM microprocessor S3C2440A. In addition, it directly modifies disturble linely of Linux to improve ability of real-time responsiveness. And then improves rate of processing and transporting data. It adopts GPRS module MC35 to realize seamless connection and data transmission. The tests show that this system can realize data transmission real-timely.
