Description

一种盲人智能眼镜 技术领域
本发明涉及信息通信技术领域，尤其涉及一种盲人智能眼镜。
背景技术
导盲眼镜是一种专门供盲人、白内障患者及其他暂时失一明者导盲探测装置。目前，采用比较多的导盲眼镜是 CDM-I 型导盲眼镜，该导盲眼镜由电子盒和眼镜两部分组成。眼镜上装有两只超声换能器和一只耳塞机，换能器能够向前方发射和接收反射回来的超声脉冲波，盲人通过耳机发出的声音变化而感知前方的障碍物。导盲眼镜对小障碍物的探测范围是正前方，左右各 10 度、上方 5 度、下方 35 度，在离眼镜 2 米远的地方，可以探测到左右各 0.4 米、上方 0.2 米、下方 1.4 米的空间范围内的障碍物；对于大的障碍物，探测范围还要大些。探测距离分 1.5 米和 4 米两档，由电子盒上的拨动开关选择。当在一定距离内遇到障碍物时，耳机便发出声响，障碍物越近，声音重复得越急促，音调也越来越高。电源采用一节 9 伏 6F22 叠层电池，一节电池可使用 60 小时。使用时，先戴好眼镜，选择好距离档：在人多的地方应选 1.5 米的距离档，在人少的地方可选 4 米的距离档。
这一高科技产品一投放市场就以它设计灵巧、美观大方、使用方便。自本品问世以来国内外反响很大，国内外报刊作了大量的报道。导盲眼镜是将集成电路装置安装在眼镜架和眼镜片上，超声装置不断向前发射超声波，当遇到障碍物时即反射回来，经眼镜上的超声波接收装置接收后，通过电子线路的处理，变成可听见的声音，该声音的音调及重复频率是随着障碍物的距离改变而变化，盲人可以根据声音、音调及重复频率来判断前方有无障碍物及障碍物距离，从而避免了碰撞，使盲人行走方便，减少碰撞的痛苦，是盲人导盲引路的先进工具。
但是，上述产品仅能够判断盲人前方有无障碍物及其距离，并不能设身处地地考虑盲人行走的需求，本发明采用嵌入式系统软硬件技术，采用大规模集成电路，采用移动通信技术，采用了GPS定位技术，采用了GPS导航技术，采用了传感器技术，采用了语音识别技术等，从而在图像采集，基带数字信号处理，图像分析，语音播报，语音识别，语音导航方面为盲人提供更好的导盲服务。

所述盲人智能眼镜还包括：包括多个子传感器的传感器组件 4 ，依据传感器的作用不同，不用的子传感器可以设置于：镜架前部 1 、镜片 2 、镜腿 3 ；传感器组件 4 的子传感器用于检测所述盲人智能眼镜的各个状态参数；控制模块 5 可依据布线需要设置于以下任意一处：镜架前部 1 、镜片 2 、镜腿 3 ；控制模块 5 一般为 MCU (Micro Control Unit) 中文名称为微控制单元，是指随着 大规模集成电路 的出现及其发展，将计算机的 CPU 、 RAM 、 ROM 、定时计数器和多种 I/O 接口集成在一片 芯片 上，形成芯片级的计算机，为不同的应用场合做不同组合控制。控制模块 5 一般用于依据所述 传感器组件 4 所测得的状态参数执行预设的决策机制。例如：依据测距传感器所测得的障碍物距离，控制模块 5 向盲人用户发出预警提示。
图 2 为本发明第一实施例提供的 一种 盲人智能眼镜 的 框图，如图 2 所示， 在该盲人智能眼镜内部，传感器组件 4 与控制模块 5 电性连接。优选的，该盲人智能眼镜采用电池供电，该电池采用充电电路与锂电池的结合，耦接至控制模块为盲人智能眼镜供电，该充电电路包括 ChargerIO ， ChargerIO 可保证充电的同时使用该盲人智能眼镜。
图 3 为本发明第二实施例提供的一种盲人智能眼镜的结构示意图，如图 3 所示，传感器组件 4 包括重力传感器 41 、加速度传感器 42 、以及指南针传感器 43 ；
所述重力传感器 41 用于检测所述状态参数中的重力感应值，并将所述重力感应值回传至所述控制模块 5 ；重力传感器是根据 压电效应 的原理来工作的。所谓的压电效应就是'对于不存在对称中心的异极晶体加在 晶体 上的外力除了使晶体发生形变以外，还将改变晶体的极化状态，在晶体内部建立电场，这种由于机械力作用使介质发生极化的现象称为正压电效应'。重力传感器 41 利用了其内部的由于 加速度 造成的晶体变形这个特性。由于这个变形会产生 电压 ，只要计算出产生电压和所施加的加速度之间的关系，就可以将加速度转化成电压输出。当然，还有很多其它方法来制作 加速度传感器 ，比如电容效应，热气泡效应，光效应，但是其最基本的原理都是由于加速度产生某个介质产生变形，通过测量其变形量并用相关电路转化成电压输出。通过重力传感器测量由于重力引起的加速度，可以计算出设备相对于水平面的倾斜角度。即盲人用户的 行走姿势是否倾斜。
所述加速度传感器 42 用于检测所述状态参数中的速度变换值，并将所述速度变换值回传至所述控制模块 5 ；加速度传感器是一种能够测量加速力的电子设备。加速力就是当物体在加速过程中作用在物体上的力，就好比 地球引力 ，也就是 重力 。加速力可以是个 常量 ，比如 g ，也可以是 变量 。 加速度计 有两种：一种是角加速度计，是由 陀螺仪 （ 角速度传感器 ）的改进的。另一种就是线加速度计。通过分析动态加速度，可以分析出设备移动的速度。即盲人用户的行走速度。
所述指南针传感器 43 用于检测所述状态参数中的移动方向，并将所述移动方向回传至所述控制模块 5 ；指南针传感器主要由地磁传感器组成。现在的地磁传感器最小所能分辨出的方向角的误差是± 0.1 ° ，当每秒响应速度为 4 次时，每秒响应速度为 20 次时则大致为± 0.2 ° 。即测盲人用户的行走方向。

该实施例中，控制模块 5 还用于依据所述倾斜角度、所述移动速度、以及所述移动方向执行所述决策机制，其中，所述决策机制为控制所述语音输出模块 6 输出所述第一语音信息。该实施例主要用于检测盲人用户的行走过程，例如：盲人用户佩戴该盲人智能眼镜时前进，当行进方向错误、行走姿势倾斜或者行走速度过快时，进行语音播报及发出提醒声音的第一语音信息，该第一语音信息一般为：'危险，行进方向错误''行进速度过快，请减慢行进速度'……等等。该实施例还用可以增设一用于进入该行走模式的按键，该按键用于触发该行走模式，行走模式包括以下步骤：
S1 、用户按下按键，进入行走模式；
