摘要
为分析环境温度对同步开关动作时间的影响,设计了一种温度检测系统。系统电路由DSP芯片TMS320F2812、数字温度传感器DS18B20及液晶显示模块实现,采用单线总线测温,给出了测温系统电路的工作原理图和程序流程,最后给出了测温实验结果。结果表明,该测温系统具有检测方便、精度高和抗干扰能力强等优点。
A temperature measuring system was designed to analyze the influence of ambient temperature on operating time of synchronous switch. This system was composed of DSP TMS320F2812, digital temperature sensor DS18B20 and LCD display module, and adopted single-line bus temperature measurement. The diagram and flow chart of working principle of this temperature measurement system circuit were given. The results show this system features with convenient detection, high precision and anti-interference ability.
