基于DM642和CDMA的无线远程监控系统
|
摘要
本文主要介绍基于TMS320DM642和CDMA无线数据模块的无线远程监控系统的设计与实现。为提高设备驱动程序的代码可重用性,以视频解码芯片TVP5150A为例,介绍了开发设备驱动程序的通用方法,提出了把驱动程序分为类/微上下两层驱动的概念。为将经过MPEG-4压缩后的码流和采集到的现场设备工作数据发送到远程监控机,实现无线远程监控的功能,需要开发CDMA无线数据模块的网络连接程序和数据通信程序,其中的数据通信程序根据我们自己定义的通信交互协议进行开发。同时,本文还给出了实现无线视频传输的设计与实现,就是通过DM642的EDMA和MCBSP实现其与CDMA无线数据模块的串口通讯,这样就可以利用EDMA传输快速、高效的特性,且数据传输工作不需要CPU参与,在后台进行。另外,为实现EDMA的数据连续传输,采用了PING-PONG缓存和EDMA传输中断。由于TMS320DM642特殊的引导机制,即在上电复位时只能自动引导1KBYTES代码,提出了二级引导程序概念,并介绍了其设计与实现。
本文最后对全文作了总结,并对TMS320DM642在无线通信嵌入式产品中的广泛应用作了展望。
This thesis mainly introduces the design and realization of a wireless remote monitor system based on TMS320DM642 and CDMA wireless data modem. In order to maximize the re-use of device driver's code, a general method used for developing device driver is introduced taking the example of video decode TVP5150A and a concept is put forward that driver can be divided into two layers: class/mini driver denoting driver's upper layer and lower layer, respectively The network connecting program for CDMA modem and the data communication program need to be developed for transmitting the image compressed in MPEG-4 standard and field instrument's operating data to the remote monitor, and the data communication program is based on the protocol defined by the developers. Design and realization of wireless video's transferring by combining EDMA and MCBSP to connect to CDMA modem is introduced, in which EDMA's property: transferring data in high speed and efficiency and working in background without CPU's intervention plays an important role. In addition, PING-PONG buffering and EDMA transfer interrupt is used to realize the EDMA's continuous operation. Secondly bootloder is needed to be developed for an embedded system based on TMS320DM642, because it could only boot lk bytes code by chip-on bootloader following the release of/RESET while the CPU is stalled.The last part gives the a conclusion and describes the future of embedded systems based on combination of TMS320DM642 and wireless communication technology.
