发布时间：2019-06-09 18:19
【摘要】：触摸感应技术是一种基于信号识别技术基础上的新型电子控制技术,作为一种传统输入方式的升级换代技术,应用在对各种电子设备的信息输入和操控上,给输入设备的人机交互界面带来了革命性的变化。 触摸感应技术的基本原理是以捕捉人体手指的触摸动作信息为基本出发点,将手指触摸动作的信息转化成电信号并加以识别。主流的触摸感应技术主要基于电阻或者电容感应原理,结合现代微电子技术集成电路能够可靠地捕捉手指的触摸信息。 本文的主要研究目的是提出一种适合于小空间和翻转结构的触摸按键的设计应用方法。 在电气设计方面,对于翻转结构给触摸按键信号识别所带来的干扰,通过合理的硬件设计和软件调试,解决了经常困扰触摸按键设计人员的误动作问题；对于小空间的设计问题,因其对于PCB的尺寸有较大的限制,将传统的底部LED背光源,改到按键的侧面,使用创新的导光片结构设计保证了发光效果。 在结构设计方面,对于极小的空间,通过采用高强度的铝材同时作为装饰面板和框架,既实现了触摸按键信号采集对于稳定性的要求,也成功实现了在狭小空间内设计满足强度要求的翻转结构。 最后,结合本文设计的特点,给出了该产品设计的测试和评价方法,对于硬件和软件方面的重点课题也给出了相应解决办法。
[Abstract]:Touch induction technology is a new type of electronic control technology based on signal recognition technology. as a kind of upgrading technology of traditional input mode, touch induction technology is applied to the information input and control of various electronic devices. It has brought revolutionary changes to the human-computer interface of the input device. The basic principle of touch induction technology is to capture the touch action information of human fingers as the basic starting point, and convert the information of finger touch action into electrical signal and recognize it. The mainstream touch induction technology is mainly based on the principle of resistance or capacitance induction, and the integrated circuit of modern microelectronics technology can reliably capture the touch information of fingers. The main purpose of this paper is to propose a design and application method of touch button suitable for small space and flip structure. In the aspect of electrical design, the interference caused by the flip structure to the recognition of touch button signal is solved by reasonable hardware design and software debugging, which often perplexes the touch button designer. For the design of small space, because of its great limitation on the size of PCB, the traditional bottom LED backlight source is changed to the side of the key, and the innovative light guide structure design is used to ensure the luminous effect. In the aspect of structural design, for very small space, the stability requirement of touch key signal acquisition is realized by using high strength aluminum as decorative panel and frame at the same time. The flip structure which meets the strength requirements is also successfully designed in a narrow space. Finally, according to the characteristics of this design, the test and evaluation method of the product design is given, and the corresponding solutions to the key issues of hardware and software are also given.
