摘要
给出了一种基于PROTEUS仿真实现的数字温度采集系统设计。系统以ARM7芯片LPC2114、实时嵌入式操作系统uC/OS-Ⅱ和数字温度传感器DS18B20为基础,进行温度采集,且用虚拟示波器实现了延时函数的精确延时,解决了温度采集中关键的时序问题。通过PROTEUS对温度采集系统的工作过程进行模拟,以检验和评估设计的可行性和稳定性,是一种有效可行的仿真方法。
It constructs a proteus-based digital temperature acquisition simulation system. The system gathers temperature by a ARM7 chip lpc2114,a real-time embedded OS uC/OS-Ⅱ and a digital temperature sensor DS18B20 .The accurate time-delay function was realized by a virtual oscillograph and it solved the key time sequence problem.The temperature acquisition system＇s working process was simulated by Proteus to verify and evaluate the design＇s feasibility and stability and as a result it＇s a effective and feasible simulation method.
