摘要
为增大服装压力检测装置中传感器与人体贴合的顺应性,进而提高服装压力测量的精确度,提出了使用柔性薄膜传感器进行服装压力测量的方法。以聚氯乙烯作为柔性基体,包覆导电纤维制成柔性传感器,将传感器连通缓冲气室,与气泵、排气阀构成气动回路,实现服装压力与气室压力的转换;基于开发的柔性传感器,选用可编程逻辑控制器作为主控单元,研制了一款可触屏操作和存储、打印数据的服装压力检测仪;完成系统标定后通过重复性实验,验证了检测仪的测量精度和可行性,6次测量结果最大标准偏差为0.0885。研究认为,该检测仪可准确完成多点服装压力的实时测量,适用于压力服装的出厂压力检测,也为服装压力检测方法的研究、控制元件选择等提供新思路。
In order to increase the compliance of the sensor in the clothing pressure detector while it is attached to human body,and then improve the precision of clothing pressure measurement,a new method of measuring clothing pressure with flexible film sensor is presented.Using polyvinyl chloride as a flexible matrix,coated with the conductive fibers,a flexible film sensor has been designed.The sensor is connected with the buffer air chamber and the pneumatic circuit is constructed through the buffer chamber,an air pump and an exhaust valve,it can convert clothing pressure to air chamber pressure.Based on the flexible film sensor,a clothing pressure detector that can be operated with a touch screen as well as store and print testing data has been developed,which choose programmable logic controller as the main control unit.After the system calibration was completed,the precision and feasibility of the detector were verified by repeated experiments.The maximum standard deviation of the six measurements was 0.0885.The detector can measure the pressure of clothes at multiple point accurately in real time.It can be used for product testing in pressure garment factories,and it also provides a new idea for the research on clothing pressure detection method and the selection of control elements.
