单总线技术在航空相机温控系统中的应用

航空成像设备通常需要对温度敏感区进行分区控制。以往的温度传感器多采用热敏电阻，它易损坏，长时间使用后需重新标定，狭小空间下的多传感器布线非常复杂，保证模拟信号远距离测量的精度在技术实现上也比较困难。提出了采用一种基于单总线技术的新型数字温度传感器DS18820U的测温系统。实验结果表明，基于DS18820U的单总线传感器网络具有测量精度高，测温范围宽，布线少，无需标定等特点，特别适合航空成像设备在空间受限，多传感器远距离布线特点下的温度组网测量。

Application of 1-wire Bus Technology in Temperature Control System of Aerial Camera

Aviation imaging equipment needs to control temperature according to different temperature-vulnerable areas.Conventional thermometer normally takes thermistor as the temperature sensor.It is easy to be broken and complicated to wire in a space-constrained area.It needs to be calibrated again after long-term operation.It is difficult to ensure the detection accuracy of analog signals in a distant transmission.A new type temperature detection system with digital temperature sensor DS18B20U which can solve thi...
