In order to solve this problem we design the stelliform system bus to carry the voltage. 为此，本系统中设计了呈星型的总线结构，很好的解决了这一问题。
The system hardware makeup ,sensor's stelliform connection topology configuration ,realization method of DS18B20 automatic addressing and taxis are emphatically dissertated. 重点论述了系统硬件组成、传感器星型接线拓扑结构、DS18B20自动寻址和排序实现方法。
