【摘要】 涡街流量计具有结构简单牢固、无可动部件、可靠性高、寿命长、测量范围宽等优点,所以自从投放市场以来,得到广泛地应用。但目前大多数涡街流量计的供电均采用交流电源方式供电,这样不但增加现场安装施工的难度,同时极易引入电源干扰。因此研制一种可以电池供电的微功耗、抗干扰能力强的涡街流量计具有非常重要的意义。目前GSM在国内已形成覆盖网络,它具有保密性高、抗干扰能力强、可靠性高、开发性强等特点,保证了数据传输的准确性和稳定性,并提供双方完备的通信协议,使用户在此通信平台上的开发简单易行。短消息业务SMS(ShortMessage Service)作为GSM网络的一种基本业务,已经得到越来越多的重视,其简便快捷的性能和相对低廉的收费赢得了广大用户的青睐,同时也为远程数据传输提供了一种新的技术手段。涡街流量计的使用环境复杂,使用RS232进行数据传输已经逐渐地不能满足用户的要求,而短消息业务具有RS232无与伦比的优越性,所以采用短消息业务来完成小流量数据传输已经越来越受欢迎。本文介绍了短消息业务SMS的原理及特点、涡街流量计的硬件设计和软件设计。单片机系统是硬件电路的核心部分,为了降低系统的功耗,采用了TI公司的MSP430单片机作为系统的控制器,MSP430是TI公司推出的一种超低功耗单片机。程序采用MSP430 C语言编程,在IAR Embedded System开发环境中开发。为了缩短开发周期,采用专门的GSM Modem来完成数据的传输。更多还原

【Abstract】 Since the Vortex flowmeter is available on the market, it finds wide use because of its simple structure, no movable components, high reliability, long life, high accuracy, and wide measuring range. However, most of the vortex flowmeters nowadays adopt the AC power supply mode. It makes field installation more difficult and liable to introduce power interference. So it is necessary to develop a low-power and high anti-interferenced vortex flowmeter powered by the battery.At present, GSM network has covered the whole country. On account of its high privacy, anti-interference ability, reliability and easy development, the accuracy and stability of data transmission are guaranteed. GSM provides integrated communication protocol to both sides so that the development works for the users become easier on the communication platform. As a basic business of GSM network, the SMS (Short Message Service) has already absorbed attention and favor of more users because of its high speed and relatively low price. At the same time, it also offers a new means for long-distance data transmission.The use environment of vortex flowmeter is complicated. So data transmission with RS232 becomes unsuitable for users’ needs gradually. With incomparable advantages of SMS over RS232, it becomes more and more welcome to use SMS for the transmission of small-streamed data.This paper introduces the principle and characteristics of SMS, the hardware and software design of vortex flowmeter.The single-chiped micro-computer(SCM) system is the core of hardware design. In order to reduce power consumption, an ultra-low-powered MSP430 typed SCM manufactured by TI company is chosen as the system controller. The whole control procedure adopts MSP430 C language to program in the IAR Embedded System development environment. In order to shorten development period, the special GSM Modem is adopted to transmit data.更多还原
