摘要毛皮动物的养殖能够带来较高的经济收益，能否精准的判断毛皮母兽的发情程度，将直接影响到母兽的繁殖育种的成功率，是养殖工作的重要部分。传统的母兽发情程度检测技术效率较低，需要新的技术创新来满足当前的毛皮养殖规模。本设计根据传感器检测和生物电阻抗两种技术，设计出用于确定狐、裘等毛皮母兽阴道黏液阻抗值的发情程度检测仪传感器部分。该传感器的本质是两个测量电极，通过4066芯片控制电路的通断，以两个电极实现四个电极的功能，不仅防止了测量电极的极化，而且使测量结果更加准确。通过测量精确电阻对检测仪传感器进行标定，再测量已知电导率的标准溶液，将测量结果与溶液的实际阻抗值画成折线图进行比较，发现该装置可以测出准确结果。因此，本设计可用于判断毛皮母兽的发情情况。74036

Degree of Fur Animal Heat Detector Sensor Design and Performance Test

Abstract Cultivation of fur-bearing animals can bring about great economic benefits。 Whether to judge the heat degree of the female fur-bearing animals precisely-an   important part of breeding work, is a direct factor which will affect the breeding success rate of the female fur-bearing animals。 The traditional mother's estrus detection technology has poor efficiency which needs a new technological innovation to meet the current scale of the cultivation of fur-bearing animals。 This design is based on sensors and bioelectrical impedance technology and try to devise the sensor part of the degree of heat detector used to determine the fox fur mother's vaginal mucous electrical impedance values。 The essence of this sensor is the two measuring electrode using the 4066 chip to control the handover of the circuit。 Making two electrodes function as four electrodes can not only prevent the polarization when measuring the electrode, but also can make the measurement results be more accurate。 Firstly we can calibrate the detector sensor by measuring the accurate resistance, then measure the standard solution of known conductivity。 Afterwards the line charts of the measured results and the actual impedance values of solution can be drawn to make a comparison 。Finally it is found that the device can measure the accurate results。 Therefore, this design can be used to judge the heat degree of the female fur-bearing animals。
