笔者将电场测试集成微系统应用于安全领域中的近场测试中.通过对电容理论的扩展以及对不同类型电容模型的理论分析,证实了其原理的可行性.在对内交叉电极和螺旋型电极比较的基础上,设计选用了有良好效果特性的螺旋型电极.结合微处理器设计了电场测试集成微系统,并在空气介质和水介质中进行了近场探测实验.当有物体靠近电极时,会影响电极间的电场环境参数,输出测试电压值相应地发生变化.靶场实验结果也证明了该测试系统的可行性.
The author applies the electric field test integrated microsystem to the near field test in the field of security, and through the expansion of the capacitance theory and the theoretical analysis of different types of capacitance models, the feasibility of the principle is proved.In the cross-electrode and spiral Based on the comparison of the electrodes, the helical electrode with good effect was designed and designed, and the integrated micro-system of electric field test was designed with microprocessors, and the near-field detection experiments were carried out in air and aqueous media. , Will affect the electric field environment parameters between the electrodes, the output test voltage value changes accordingly.Field field test results also proved the feasibility of the test system.
