为了解决现有含水率和矿化度不能全范围、精确检测的问题，本发明提供了一种含水率和电导率检测系统，其能够实现含水率、矿化度的全范围检测，保证检测精确度，同时，本发明还提供了对应的检测方法。
 技术解决方案
其技术方案是这样的：一种含水率和电导率检测系统，其特征在于，其包括双面微带电路和检测电路，所述双面微带电路包括屏蔽接地层，所述屏蔽接地层一面设置有测量侧电路、另一面设置有参考侧电路，所述测量侧电路与所述参考侧电路均包括绝缘层和导线，所述测量侧电路的测量导线与所述参考侧电路的参考导线长度、材质均一致，所述检测电路包括连接微处理器的信号发生器，所述信号发生器连接功分器输入端，所述功分器的两个输出端和接地端分别电控连接所述参考导线一端、所述测量导线一端、所述屏蔽接地层一端，所述参考导线另一端通过移相器连接鉴幅鉴相器的一个输入端，所述测量导线另一端、屏蔽接地层另一端分别连接所述鉴幅鉴相器的另一个输入端和接地端，所述鉴幅鉴相器的输出端连接所述微处理器，所述测量侧电路接触被测介质，所述参考侧电路接触空气或者接触低介电常数材料。
 有益效果
其进一步特征在于，所述测量侧电路的测量侧绝缘层与所述参考侧电路的参考侧绝缘层材质相同且厚度一致；所述信号发生器输出200-960MHz的可变频率信号，所述功分器分出1:1两路信号分别输出给所述测量侧电路与所述参考侧电路；所述测量导线一端通过一根贯穿所述测量侧绝缘层、所述屏蔽接地层、所述参考侧绝缘层的高频屏蔽线连接所述功分器，所述测量导线另一端通过另一根贯穿所述测量侧绝缘层、所述屏蔽接地层、所述参考侧绝缘层的高频屏蔽线连接所述鉴幅鉴相器；所述屏蔽接地层上开有与所述高频屏蔽线配合的密封绝缘过孔；所述参考侧电路侧设置有密封罩壳，所述密封罩壳内填充有所述低介电常数材料；所述微处理器连接通讯电路。

 附图说明
图1为本发明原理图；图2为双面微带电路具体结构示意图。
 本发明的实施方式
见图1，图2所示，一种含水率和电导率检测系统，其包括双面微带电路和检测电路，双面微带电路包括屏蔽接地层3，屏蔽接地层3一面设置有测量侧电路、另一面设置有参考侧电路，测量侧电路包括测量侧绝缘层2与测量导线1，参考侧电路均包括参考侧绝缘层4和参考导线5，测量侧电路的测量导线1与参考侧电路的参考导线5长度、材质均一，测量侧绝缘层2参考侧绝缘层4材质相同且厚度一致，检测电路包括连接微处理器的数字高频信号发生器，数字高频信号发生器连接高频功分器输入端，高频功分器的两个输出端OUT1、OUT2和接地端GND分别电控连接参考测量导线1一端、参考导线5一端、屏蔽接地层3一端，参考导线5另一端通过移相器连接鉴幅鉴相器的一个输入端IN2，测量导线1另一端、屏蔽接地层3另一端分别连接鉴幅鉴相器的另一个输入端IN1和接地端GND，鉴幅鉴相器的输出端输出相位信号和幅度信号给微处理器，测量侧电路接触被测介质，参考侧电路接触空气或者接触低介电常数材料，低介电常数材料即介电常数k比较低（低于二氧化硅，k=3.9）的电介质，主要应用在微电子领域，当接触低介电常数材料时，需要在外面设置密封罩壳，然后在密封罩壳内填充有低介电常数材料。
由于测量侧电路需要与被测介质接触，且被测介质为原油等液体，为了保证能够可靠检测，需要将测量导线两端引出到参考侧电路一侧后与高频功分器、鉴幅鉴相器电控连接，因此采用了如下结构：测量导线1一端通过一根贯穿测量侧绝缘层2、屏蔽接地层3、参考侧绝缘层4的测量侧高频屏蔽线7连接高频功分器，测量导线1另一端通过另一根贯穿测量侧绝缘层2、屏蔽接地层3、参考侧绝缘层4的测量侧高频屏蔽线8连接鉴幅鉴相器，屏蔽接地层3上开有与测量侧高频屏蔽线7、8配合的密封绝缘过孔6；由于两根测量侧高频屏蔽线7、8贯穿到参考侧电路一侧，参考导线5需要与测量导线长度一致，因此如图所述布置，参考导线5两侧也设置了参考侧高频屏蔽线9、10。
信号发生器输出200-960MHz的可变频率信号，功分器分出1:1两路信号分别输出给测量侧电路与参考侧电路。
一种含水率和电导率检测方法，其包括以下步骤：（1）微处理器控制信号发生器发出200-960MHz的微波信号，经过功分器分出1:1两路信号给测量侧电路与参考侧电路；根据微波传输理论，微波传输速度公式为：
Figure 895271dest_path_image001
其中c为光速，ε为混合介电常数，μ为磁导率。磁导率为1可以忽略，这样微波的传输速度取决于混合介电常数。参考侧电路的混合介电常数由参考侧绝缘层介电常数和空气或者低介电常数材料填充物组成，在恒温条件下是一个固定不变的值。测量侧电路的混合介电常数由测量侧绝缘层介电常数和被测介质的介电常数组成。（2）当测量侧电路与参考侧电路接触的介质相同且都不含水分时，测量导线与参考导线上的微波信号传输速度一样，相位相同；当测量侧电路接触的被侧介质含水时，测量导线上的微波信号传输速度降低，与参考导线上的微信号产生相移，通过鉴幅鉴相器的比较，得到被测介质含水率；具体的，鉴幅鉴相器输出的相位直流电压信号Vp对应测量导线和参考导线的相差，在测量被侧介质含水率之前，先进行不含水介质和纯水的标定，譬如纯油和纯水。通过标定得到在纯油介质下的相差信号Vpo，纯水时为Vpw，即标定了含水率0-100%，而且Vpo<Vpw,这两个参数存储在微处理器里面。在实时测量时，相差信号为Vpx，那么被侧介质的含水率α计算公式为：α=（Vpx-Vpo）/（Vpw-Vpo）。（3）当测量侧电路与参考侧电路接触的介质相同且都不含水分时，电导率一致，测量导线与参考导线上的微波信号的幅度和衰减程度一样；参考侧电路的介质恒定而且电导率很低接近为0，因此参考导线上的微波信号幅度衰减恒定，当测量侧电路接触的介质含水或矿物质时，电导率变高，测量侧导线的微波信号幅度相对参考侧导线的微波信号幅度产生衰减，通过鉴幅鉴相器比较，得到与幅度比值的对数相对应的直流电压信号，微处理器对该直流电压信号进行采集处理被测介质的电导率，最后根据电导率得出对应的矿化率，由于电导率和矿化率存在对应关系，计算得到电导率后即可得出对应的矿化率。具体的，鉴幅鉴相器输出的相位直流电压信号Va对应测量导线和参考导线的幅差，在测量介质电导率之前，先进行标准电导率溶液的标定，譬如电导率为0的纯水，以及电导率高的溶液，具体的电导率由量程范围决定。通过标定得到电导率为0时的幅差信号Va0，满量程电导率时为Va1，Va0>Va1,这两个参数存储在微处理器里面。在实时测量时，幅差信号为Vax，那么混合介质的电导率σ计算公式为：σ=（Va0-Vax）*range/（Va0-Va1），range是仪器的电导率测量满量程。
由于微处理器连接通讯电路，可以将测得结果通过通讯电路传输出去。
