NavEye： 为盲人学生的智能指南

目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。 -Intelligent machines in the current hardware on many dual-cpu architecture of a baseband processor are mainly deal with digital signals, voice signals, and GSM codecs communication protocol, and the other is the application processor, operating system and applications running procedures. Baseband processor, radio frequency and other peripheral chips, as a module, as a GSM/GPRS modem, provided by AT command interface. Application of network needs is a hot spot, and most of the current GSM module can support GPRS function. Application processor through the AT command set and functionality with GPRS wireless communication module, in order to achieve the application of the network provides a bottom support.

串口通讯程序，用VC++做，可以传输大文件-the program of communication of serial port,which is programmed with the tool of VC++ and can transfer big files.

今年上半年我为现公司一款流量计产品编写的上位机Modbus通讯程序（下位机程序也是我用C编写的，由于受到法律许可限制，在此不能上传，不过在将来我会把设计思路传上共享），包括自创的Modbus协议的Delphi实现及其完整调用，还有一份我编写的该产品的完整的Modbus协议说明书，非常有参考价值。-First half of this year the company I am now prepared a flowmeter products PC Modbus communications procedures (the procedures are under-bit machine I use C prepared, because of license restrictions by law, can not upload here, but I will in the future design ideas Chuan-share), including self-Modbus protocol Delphi to achieve their full call, there is also a preparation of the product I am a complete Modbus protocol specification, a very good reference material.
