摘要
为了减少温度变化对高精度时间比对的影响,设计了一种由带存储功能的数字温度计DS1624构建的、基于I2C总线的温度监测系统,并给出了系统的构成及软件、硬件实现方法和详细实验结果。分析表明,以温度监测系统为关键部分的温度控制系统是高精度时间比对所必要的。
In order to reduce the effect of temperature variation on high-accuracy time and frequency comparisons, a temperature monitoring system based on I^2C bus, which is constructed with the digital thermometer and memory DS1624, is designed. The composition and the realization of hardware and software for this system are expounded in this article. The experiment result is given in detail and an analysis shows that the temperature monitoring system as the key part of the temperature control system is necessary for high-accuracy time and frequency comparisons.
