摘要

无线数据传输技术在测控领域得到越来越广泛的应用，该技术最大的特点是通信双方省去布线，易于维护。无线数据传输技术为现代测控仪器的连接提供了灵活的结构设计方案，特别是在一些难于采用导线连接的环境中。本文的双级测控系统由单片机构成的下位机完成现场信号的采集工作，并借助无线通信模块将数据传送到上位机（PC机）进行进一步处理。文中主要包括三部分内容：一是系统硬件的选用及电路设计。其中，微处理器MCU选用的是美国TI 公司出品的新型16位RISC结构的MSP430微处理器；无线数字传输器件采用SRWF-108型微功率无线数传模块。二是下位机系统软件部分的开发。程序采用MSP430微处理器的汇编语言编写。该语言是一种典型的精简指令集系统。结合16位的总线结构，大大增加了程序运行总体速度。三是上位机数据通信与管理程序的设计。采用易学、易用的VB6.0开发。

Abstract

The wireless data transmission technology obtains the more and more widespread application in the observation and control domain, this technical most major characteristic is that the both corresponds sides can avoid the wiring, it is easy to maintain. Wireless data transmission technology to modern monitoring equipment connected with the structural design provide a flexible programme, Especially in the environment of difficult using the wire connected. In this double computer system，the nether computer which constitutes by the microprocessor completes the gathering work of scene signal , and transfer the data through wireless module to the upper computer (PC) for further processing.The article mainly includes three parts of contents: One is the system hardware selects and the circuit design. Among them, MCU selects new 16 RISC structure MSP430 microprocessor which is American TI Corporation produces ; The wireless digital transmission component uses the SRWF-108 micro power wireless module. Two is the nether computer system software part developments. The procedure uses the MSP430 microprocessor the assembly language compilation. This language is one kind of typical simplification set of instructions system. Unifies 16 bus structures, greatly increased the procedure movement overall speed. Three is the upper computer data communication and the executive program design. Uses the VB6.0 development.It is easily to study and easily to use.

Key words: MSP430 microprocessor, the SWRF-108 wireless modules, Serial communication, MSComm component
