Description

一种基于应力发光的新型电子签名触感笔 技术领域
本发明属于电子签名设备技术领域，尤其涉及一种基于应力发光的新型电子签名触感笔。
背景技术
目前，业内常用的现有技术是这样的：
传统的纸质签名，在世界范围内都广泛应用，全国因在柜台式的业务办理，车辆及驾驶人、银行存取款单、保险办理、商场、酒店入住等行业的书面签名需要大量的签名，对纸张的需求居高不下，一方面造纸会引起过量砍伐树木造成土地荒漠化；另一方面这些签名材料需要占据较大的物理存储空间(档案室)和耗费大量的人力和财力；加之，无论实生活还是工作中，效率优先，而电子签名的出现，让可以跨越时空完成签名。类似合同，可以在另一个地方电子签名传回另一个地方，无需自己奔赴现场签名，大大提高了效率。电子签名在电子商务交易过程中起着不可缺少的重要作用。现下医院的电子病历也可应用上电子签名笔，以防止医院技术篡改或抵赖，保障患者的权利。电子签名由于其能通过网络轻松便捷地提供了使用者的身份验证和体统记录，突破了时间和空间上的局限性，因此被广泛应用于通信、电子商务、电子政务和信息安全等领域。随着物联网技术的不断发展，传统柜面业务的办理正在朝着数字化、信息化的方向靠拢。为了减少繁琐的单据带来的种种麻烦，柜面业务近年来采取了“无纸化服务”行动，电子签名系统就是其中最为重要的一环。
目前市场上电子签名笔大致分为电阻式、电容式、电磁式。电阻式是利用阻值变化引起位置传感没有压感信息；电容式是通过人体电流感应引起位置传感市面上推出了很多种电容式触摸笔，为保证对电流的传导，笔身基本上都采用导电金属，致使笔的质量较重，长期用笔感觉到不适，并且在真实运笔时， 笔头是触点，而作为触点的导电硅胶是柔软的、易变形、不能很好的支撑来自手腕的力量，书写体验不好；电磁式是电磁感应引起位置传感含有压力信息但是内置压力传感器，所以是需要能够发射电磁信号和内置压力传感器的手写笔和电磁式触摸板共同建造的，二者无法分开。POS机、手机等小型电子设备尚且可以方便携带，但如手绘板、手绘屏等中型电子设备，不仅面积大且无法弯曲折叠，这将会存在携带不方便的问题。
综上所述，现有技术存在的问题是：电阻式与电容式手写笔发展较早，属较为低端类产品，只能单一表征出书写过程中的位置信息，即线条单一化，无法比拟现实生活中笔迹随用力的不同而有轻微区别的真实墨水书写体验。电磁感应式手写笔属较高端产品，不仅可以表征位置信息，同时笔中设置的传感器可以传感压力信息，使书写体验更加真实，但其存在的不足在于于电磁感应式的位置传感是依靠手写笔和手写板之间建立的电磁场而实现的，因此电磁式手写笔总脱离不开手写板的束缚。而建立的基于弹性应力发光材料的智能手写笔，将应力发光材料作为压力传感的承担者，让书写信息真实化、多元化，从而得到更加广泛的应用。
解决上述技术问题的难度和意义：
从国内外的经验来看，电子签名已经在电子商务，电子政务领域非常成熟了，今后我国的发展也离不开电子签名。随着信息化建设的加速，国民经济和社会信息化的领域越来越广阔，应用也越来越深入，电子签名的应用范围也会越来越巨大。所以，在电子签名领域迫切需要解决的问题是提高电子签名笔迹的真实还原性，以及电子签名笔的便携性。本发明在电子签名笔迹还原的基础上，致力于具有个性特征的书写压力记录，使得电子签名的安全性进一步提高，将有利于电子签名应用的推进。

进一步，所述应力发光材料至少含有ZnS:Mn与ZnS:Cu和CaZnOS:Tb/Pr/Sm/Ho/Dy/Er/Eu/Tm/Nd/Yb与CaZnOS:Mn中的一种或多种。
本发明的另一目的在于提供一种所述应力发光笔头的制作方法，所述应力发光笔头的制作方法将环氧树脂AB胶203的本液和硬化剂按3：1的质量比均匀混合；将混合后的未固化AB胶与应力发光粉ZnS:Mn按1：1的质量比均匀 混合而成，作为应力发光层；再将应力发光粉与AB胶的混合溶液加入模具中，待其自然固化，作为应力发光笔尖；在笔尖头部包裹上一层不易磨损的材料作为保护层，将制备好的带有应力发光材料的手写笔尖进行二次加工，置于模具中，在应力发光笔尖后加入混合硬化胶，并且将光电转换器件插入混合硬化胶溶液中，待其自然固化，笔头模型完成。
本发明的另一目的在于提供一种所述应力发光笔头的使用方法，所述应力发光笔头的使用方法为签名时，应力发光笔头应力发出光线，光电转换器将光信号转换为电信号，通过导线发送至中央处理芯片；微型摄像头拍摄写字面作为视频信号。中央处理芯片以及信号传输电路使发光产生的电信号和视频信号同步，即每得到一帧图像发送一应力发光光强信号，并且发送至上位机；上位机接收电子签名笔的信号并且进行处理，对定位部件图片使用特征点识别的方法，通过判断特征点移动方向，判断出笔的运动轨迹并且将光电转换器件的光强大小转换为笔迹的色度信息，从而实现笔迹的恢复。
实现笔迹的恢复。

综上所述，本发明的优点及积极效果为：应力发光材料是发光体受到各种机械力如挤压、摩擦等作用下产生自发光的材料。本发明笔尖的应力发光复合材料在动态外力作用下直接发射电磁波光线，光电转换器件采集笔尖发出的光学信息，而笔尖附近的微型镜头拍摄写字平面作为视频信号，然后将光学信息和视频信息传输到上位机，上位机对接收的信号进行处理，从而实现有含有力 信号的笔迹的复原。笔迹像素灰度值不同就反映出在书写过程中材料的发光亮度不同，据弹性应力发光材料特性，进而可以了解力的实时分布也不同。与传统的签名笔相比，这种签名既含有笔尖压力和笔尖摩擦的信息，又含有签名时的速度信息，而不仅仅是二维的签名图像，提高了信息的可靠性，进一步提高签名信息安全度。

应力发光笔尖201外侧包裹有保护层202，应力发光笔尖201后端浇注有混合硬化胶203，光电转换器3嵌装在混合硬化胶203内。
作为优选，光电转换器3包括光敏原件、光电池、光敏二极管、光敏三极管、CCD、CMOS。
作为优选，应力发光笔头2可以有多种不同颜色，可以使用于除签名外的更多场合。
作为优选，应力发光笔头2中含有应力发光材料和聚合物材料，应力发光材料包括但不限于：ZnS:Mn、ZnS:Cu、SrAl2O4:Eu、SrMgAl6O11:Eu、SrCaMgSi 2O 7:Eu、SrBaMgSi 2O 7:Eu、Sr 2MgSi 2O 7:Eu、Ca 2MgSi 2O 7:Eu,Dy、CaYAl 3O 7:Eu、ZnGa 2O 4:Mn、MgGa 2O 4:Mn、BaAl 2Si 2O 8:Eu、Ca 2Al 2SiO 7:Ce、ZnS:Mn/Te、CaZnOS:Tb/Pr/Sm/Ho/Dy/Er/Eu/Tm/Nd/Yb、CaZnOS:Mn、CaZnOS:Cu、LiNbO3:Pr和EuD4TEA中的一种或多种组合，较优的是组合中至少含有ZnS:Mn与ZnS:Cu和CaZnOS:Tb/Pr/Sm/Ho/Dy/Er/Eu/Tm/Nd/Yb与CaZnOS:Mn中的一种或多种。
应力发光笔头2制作时，首先将环氧树脂AB胶203的本液和硬化剂按3： 1的质量比均匀混合；然后将混合后的未固化AB胶与应力发光粉ZnS:Mn按1：1的质量比均匀混合而成，作为应力发光层。再将应力发光粉与AB胶的混合溶液加入模具中，待其自然固化，作为应力发光笔尖201；在笔尖头部包裹上一层不易磨损的材料作为保护层202，将制备好的带有应力发光材料的手写笔尖进行二次加工，置于模具中，在应力发光笔尖201后加入混合硬化胶203，并且将光电转换器件3插入混合硬化胶203溶液中，待其自然固化，笔头模型完成。
签名时候，应力发光笔头2应力发出光线，光电转换器3将光信号转换为电信号。在这个过程中，微型摄像头4拍摄写字面，经过中央处理芯片5以及信号传输器使发光产生的电信号和视频信号同步，并且发送至上位机。上位机接收电子签名笔的信号并且进行处理，从而实现笔迹的恢复。
以上所述仅是对本发明的较佳实施例而已，并非对本发明作任何形式上的限制，凡是依据本发明的技术实质对以上实施例所做的任何简单修改，等同变化与修饰，均属于本发明技术方案的范围内。
