一种温度检测传感器的设计

Design of a Temperature Detected Sensor

路面传感器在公路交通领域有着极其重要的应用,它能够对路面状况信息进行监测及警报,从而大大提高公路交通的安全系数。温度检测传感器用于监测道路表面及下方一定深度处的温度,并结合其他传感器如水膜厚度、盐度传感器等对路面状态进行综合判断。论文主要介绍温度检测传感器的原理、电路结构、测试方法等,给出数据处理的改进方法,提高检测的准确性。

Road surface sensor, which monitors the road conditions and will raises an alarm when necessa- ry, plays a very important role in the safety of transportation. The temperature detected sensor is used to meas- ure the temperature on and beneath the road surface, in order to synthetically estimate the road conditions in co- operation with other sensors such as water film sensor, salinity sensor and so on. In this paper, we introduce the theory, circuit structure, testing method of the temperature detected sensor, improve the data processing pattern and accuracy of results.
