【摘要】 介绍了用8位单片机控制的数据采集及基于GSM网络的数据无线传输系统。硬件电路采用模块化的设计思想,在实际应用中可以对各个部分进行选择组合,同样,使用C语言编写的应用程序的可移植性和伸缩性也非常强,可以根据外围电路的不同而增减相应程序功能模块。文中介绍了三种类型信号数据的采集方法及数据无线传输方式。更多还原

【Abstract】 This paper introduces a system of data acquisition, which controlled b y an eight-bit microprocessor, and wireless transmission based on GSM(Global Sys tem for Mobile Communication) network. The design of the circuit adopts the idea of modularization in the practical application; the parts can be selected accor ding to the demand, Similarly, the software design also adapts the idea of modul arization, it’s transplantlity and retractility are suitable to increase and de crease the function module according to the periphery circuit. The paper introdu ces methods of gathering three types of signal, and the methods of wireless tran smission.更多还原
