背景技术 Background technique
温度是一个很重要的环境参数，人们的生活和环境温度息息相关，工业生产过程中需要实时测量环境温度，在农业生产中也离不开温度测量，目前，在气象站和无线电探空仪等气象环境探测领域，传统温度传感器多采用铂电阻或热敏电阻进行温度测量。由于冰、雪、雨滴、云滴、露等液态或固态水可能在粘附在传感器表面，云滴、雨滴和露滴的蒸发吸热、冰雪的融化和升华都可能导致测量温度低于大气环境的实际温度，云滴、雨滴和露滴的冻结释放潜热可能导致测量环境温度高于环境温度，造成一定的测量误差。 Temperature is a very important environmental parameter. People's lives are closely related to the ambient temperature. In the process of industrial production, it is necessary to measure the ambient temperature in real time. In agricultural production, temperature measurement is also inseparable. At present, in meteorological stations and radiosondes, etc. In the field of environmental detection, traditional temperature sensors mostly use platinum resistance or thermistors for temperature measurement. Because ice, snow, raindrops, cloud droplets, dew and other liquid or solid water may be adhering to the surface of the sensor, the evaporation and heat absorption of cloud droplets, raindrops and dew droplets, the melting and sublimation of ice and snow may cause the measured temperature to be lower than the atmospheric environment The actual temperature of cloud droplets, raindrops and dewdrops may release latent heat due to freezing, which may cause the measurement environment temperature to be higher than the ambient temperature, resulting in certain measurement errors.

The control module is MSP430. the
如图1所示；一种温度测量装置及系统，包括两个测温铂电阻，所述铂电阻一般采用薄膜铂电阻；这种传感器还包括两个加热电阻和两个加热电阻的控制电路。所述加热电阻可固定在薄膜铂电阻底侧，用绝缘导热硅胶可将加热电阻和铂电阻连接，加热电阻用于对测温铂电阻进行加热烘干；所述加热电阻采用低温漂的精密电阻；所述加热电阻通过加热电阻引线连接基于MOS管的加热电阻控制电路，所述加热电阻控制电路包括与加热电阻相连接的MOS管，该MOS管的通断由一个控制器进行控制。两个铂电阻与一个电阻测量电路相连接，铂电阻通过测温铂电阻引线连接数模转换器电阻测量电路主要包括一个模数转换器（ADC），该ADC与控制器连接。 As shown in Figure 1; a temperature measuring device and system, including two temperature measuring platinum resistors, the platinum resistors generally adopt thin-film platinum resistors; this sensor also includes two heating resistors and two heating resistor control circuits. The heating resistor can be fixed on the bottom side of the thin-film platinum resistor, and the heating resistor can be connected to the platinum resistor with insulating and heat-conducting silica gel, and the heating resistor is used to heat and dry the temperature measuring platinum resistor; The heating resistor is connected to a heating resistor control circuit based on a MOS tube through a heating resistor lead wire, and the heating resistor control circuit includes a MOS tube connected to the heating resistor, and the on-off of the MOS tube is controlled by a controller. Two platinum resistors are connected to a resistance measuring circuit, and the platinum resistors are connected to a digital-to-analog converter through temperature-measuring platinum resistor leads. The resistance measuring circuit mainly includes an analog-to-digital converter (ADC), which is connected to a controller.
测量时，两组温度测量装置交替进行加热烘干、自然冷却及测温。一个传感器测量环境温度时，第二个传感器通过控制MOS管进入导通状态控制加热电阻对测温铂电阻进行加热烘干，加热时间的长度为T1。加热结束后，MOS管不再导通，第一个传感器通过空气对流进行散热，温度逐步趋近于环境温度，这段冷却时间的长度为T2。传感器冷却完成后，第二个传感器进行测温，测温的时间为T1+T2。当第二个传感器开始进行测温时，第一个传感器开始加热烘干。用这种方法，两个传感器可交替往复实现无间断测量。 During measurement, two sets of temperature measuring devices alternately perform heating and drying, natural cooling and temperature measurement. When one sensor measures the ambient temperature, the second sensor controls the heating resistor to heat and dry the temperature measuring platinum resistance by controlling the MOS tube to enter the conduction state. The length of the heating time is T1. After the heating is over, the MOS tube is no longer conducting, and the first sensor dissipates heat through air convection, and the temperature gradually approaches the ambient temperature. The length of this cooling time is T2. After the cooling of the sensor is completed, the second sensor measures the temperature, and the temperature measurement time is T1+T2. When the second sensor starts to measure temperature, the first sensor starts to heat and dry. In this way, the two sensors can alternately reciprocate to achieve uninterrupted measurement.
