| Abstract: | Under natural climate condition,in order to get temperature distribution of the internal soil of highway subgrade in seasonal frost regions at different period and different depth,apply the temperature sensor DS18B20 and STC89C58 single chip micyoco (SCM) to the measuring system of subgrade temperature field.The selection of the temperature sensor,the design of the data collecting device and of the software about the temperature measuring system,and the verifying on the precision of the measuring data by experiments are stated in detail.In this way,both a long-term,comprehensive and serial measurement and the auto-reading and auto-saving of the data can be realized. |
