摘　　要：为提升应力应变传感器对空间三维力的检测能力,提高传感阵列系统的传感性能和可靠性,本文将普通的电容式传感器阵列化,结合多通道的外围采集电路将采集到的传感器数据进行处理,探究了其在空间三维力解耦上的能力。另外将所得传感数据作为支持向量机(SVM)算法的输入端,利用SVM算法较强的泛化能力对空间三维力进行精确的解耦识别,极大地优化了整个电容式传感阵列系统的传感性能。实验结果表明,该传感系统不仅具有对空间三维力的解耦能力,并具备较高的识别准确率和稳定性,识别准确率可达到99.3%,能适用于大部分检测场景。In order to improve the ability of stress-strain sensors to detect three-dimensional forces in space,and improve the sensing performance and reliability of the sensing array system,this paper arrays ordinary capacitive sensors and processes the collected sensor data in combination with multi-channel peripheral acquisition circuits,and explores their ability to decouple threedimensional forces in space.In addition,the obtained sensing data is used as the input port of the Support Vector Machine(SVM)algorithm,and the strong generalization ability of the SVM algorithm is used to accurately decouple and identify the three-dimensional force in space,which greatly optimizes the sensing performance of the entire capacitive sensing array system.Experimental results show that the sensing system not only has the ability to decouple the three-dimensional force in space,but also has better recognition accuracy and stability,with a recognition accuracy of 99.3%,which can be applied to most detection scenarios.
