技术领域
本发明涉及一种保护视力的装置和方法，特别涉及一种学生学习保护视力的桌面装置和方法。
背景技术
现代社会患病近视眼的人占比很多，不健康用眼和不能够科学地坚持做锻炼眼睛的运动是主要的原因。同时，现有技术中没有很好的保护视力的装置以及没有很好的保护视力的方法也是一个重要的因素。因此现在应该重视保护视力的装置和保护视力的方法的研究，学生的眼睛正是处在生长发育期，学生学习的量又大、用眼的时间又长，学生学习不健康用眼对学生的眼睛造成的损伤很大，而学生的年龄又小，一定程度上决定了学生对保护视力的重要性认识不足以及对保护视力的行为缺乏主动性和自觉性，所以保护视力预 防近视的工作要从学生学习做起，最好是从小学生学习做起，要从研究和推广好的保护视力的装置和方法做起。
教育部2018年7月发布了我国首份《中国义务教育质量监测报告》，其中，学生视力不良问题突出。报告显示，我国四年级、八年级的学生视力不良检出率分别为36.5％和65.3％，其中八年级学生视力重度不良比例超过30％。此前，全国学生体质健康调研与监测结果也显示：我国小学生、初中生、高中生、大学生的视力不良率高达45.71％、74.36％、83.28％、86.36％。全国近视眼中，中小学生预估超过1亿人。如果近视人口持续增加，在航空航天、精密制造、军事等领域，符合视力要求的劳动力会面临巨大缺口，将直接威胁经济社会可持续发展和国家安全。
申请号CN201610303321的中国发明专利申请公开了一种移动显示设备主动预防近视的方法，需要在具有前置摄像头的移动电子设备上实施，通过前置摄像头对使用者进行面部识别，识别出眼睛所在区域后标识出位置点，并对位置点进行实时追踪；记录屏幕与位置点之间的实际距离以及屏幕中心轴与位置点的偏移角度；根据实际距离以及偏移角度判断位置点是否在合适的观看距离范围内，如果不在则让移动电子设备进行告警，告警后位置点仍不在合适的观看距离范围内则自动熄灭屏幕。该专利申请的技术方案不适合对学生学习看书和做作业保护视力，该技术方案不能针对学生学习的场景检测和判断学生的眼睛与书本或/和作业本之间的距离过近发出保护学生视力的告警。
申请号CN201620003333的中国实用新型专利申请公开了一种学生防近视提醒仪，适用于中小学生。包括：超声距离传感器、单片机，所述超声距离传感器与单片机输入端连接，单片机输出端分别与显示模块和语音模块连接。本实用新型通过超声距离传感器感知身体与桌子间的距离，通过振动或音乐进行提醒学生赶快调整坐姿，使身体与桌子间保持正常距离，振动或音乐即会自动停止，有效预防近视和驼背，从科学用光的角度避免眼睛疲劳， 预防近视保护视力。该专利申请通过超声距离传感器感知身体与桌子间的距离的技术方案对人的身体健康有伤害，使身体与桌子间保持正常距离的测量方法和结构不能够确定和避免学生的眼睛近距离靠近书本和作业本的不健康用眼。

可选地，所述测距传感器2或者是红外测距传感器或者是24GHz雷达传感器或者是FMCW雷达传感器或者是毫米波雷达传感器或者是超声波测距传感器或者是激光测距传感器。红外测距传感器的原理广泛应用在门禁检测和感应卫浴设施上，红外灯广泛应用于医疗保健和民用取暖；本实施例红外测距传感器的使用功率很小、结构简单、成本低，间断性测量的测量时间很短，红外测距传感器环保。
可选地，所述方法还包括：通俗地讲学生学习时眼睛与书本7和/或作业本8之间的合适距离是学生学习保护视力的健康距离，本实施例技术方案中所述学生学习眼睛与所述书本7和/或所述作业本8之间的健康距离是根据所述学生的身高和所述底座10在所述桌面6上固定设置的具体位置确定的；学生学习健康用眼合适的距离一般选择1/3m，然后再根据所述学生的年龄和/或身高作适当的调整；本实施例是间接测量的技术方案尤其要根据安装所述测距传感器2的所述底座10固定设置在所述桌面6上的具体位置最后确定。本实施例间接测量的技术方案中的所述学生学习保护视力的健康距离可以通过实际测距试验获取，选择1/3m作为学生眼睛距离书本7和/或作业本8合适的距离，再根据所述学生的年龄和/或身高作适当调整，例如一个一年级的小学生个子不高，将合适的距离1/3m再调整为30cm，所述学生是习惯于使用右手写字的，将所述底座10固定设置在所述学生正前方偏左15cm～20cm以及距离桌边>35cm(胸口方向)的桌面6上，这个时候让学生端正坐姿坐在学习的位置上并要保证学生的眼睛距离书本7和/或作业本8或桌面6有30cm距离在伏案学习，这个时候所述测距传感器2检测到的所述学生的头部与所述测距传感器2的距离就是间接测量的所述学生学习保护视力健康用眼的所述学生的眼睛距离书本7和/或作业本8之间的健康距离。在本实施例实施的过程中，所述桌面6的高度有变化的时候，要按照所述桌面6变化了的高度重新确定所述学生学习保护视力健康用眼的眼睛与书本7和/或作业本8之间的健康距离。本实施例首先是针对学生用的尤其是方便小学生使用的，小学生的书本和作业本都不厚，所述学生学习保护视力健康用眼的眼睛与书本7 和/或作业本8之间的健康距离可以是所述学生的眼睛与所述桌面6的距离。
可选地，所述方法还包括：所述测距传感器2的间接测量和判断要有一个合适灵敏度的测量判断的取值范围，比如说所述单片机15比较和判断所述测距传感器2间接测量出所述学生的眼睛与所述书本7和/或所述作业本8之间的距离小于所述学生学习保护视力的健康距离5cm，所述单片机15通过所述扬声器18发出第一提示语音和/或第一提示音乐，所述扬声器18不能频繁地发出提示影响学生集中精力学习。还要有避免学生拿学习用品被误检测和避免学生头部的偶然低头的动作被误检测的一个测量验证时长，比如说本段描述的所述单片机15验证连续5分钟以上比较和判断所述测距传感器2间接测量出所述学生的眼睛与所述书本7和/或所述作业本8之间的距离小于所述学生学习保护视力的健康距离5cm以上，所述单片机15通过所述扬声器18发出第一提示语音和/或第一提示音乐。
可选地，所述方法还包括：学生学习时眼睛靠近书本和/或作业本是有头部的动作的，是由学生的头部向下低头和身体前倾的两个动作之一或者是两个动作的组合形成的，这两个动作的一个动作发生或者是两个动作同时发生都会发生所述学生的头部位置的位移，所述学生的头部都会被测距传感器2测量出所述测距传感器2与所述学生的头部距离减少，所以所述测距传感器2测量出所述测距传感器2与所述学生的头部距离减少就是间接测量出了所述学生的眼睛与所述书本和/或所述作业本之间的距离减少了。本实施例间接测量的技术方案的测量精度满足了一种学生学习保护视力的桌面装置和方法的功能要求，该间接测量的技术方案是现有技术所没有的；测量所述学生的头部与所述测距传感器2之间的距离间接得出所述学生的眼睛与所述书本7和/或所述作业本8之间近似的距离的技术方案也是现有技术所没有的。在现实生活中，学生家长提醒学生眼睛离远书本和/或作业本也并没有学生家长真正的先去拿一把尺子去测量所述学生的眼睛与书本和/或作业本之间的距离，也都是学生的家长通过眼睛大致估计学生的眼睛距离书本和/或作业本看上去太近了，所以学生的家长向所述学生发出眼睛离远所述书本和/或所述作业本的 提示也是近似判断的。
可选地，所述方法还包括：所述测距传感器2是两个，将所述两个测距传感器2横向并排安装在所述底座10上，所述两个测距传感器2都单独测量并被分别连接所述单片机15，所述测距传感器2的测距落点是圆形的或者是其它形状的，学生学习每次坐在桌子前面的位置会有一些左右偏差的(横向偏差)，所述横向并排安装在所述底座10上的两个测距传感器2的两个测距落点也是距离合适的横向成一排的，所述单片机15对所述两个测距传感器2提供的两个测距数据的分析摒弃使用一个远距离的数据通过分析其中一个测距传感器2测量得出的所述一个近距离的数据发出所述学生的眼睛与所述书本7和/或所述作业本8之间的距离是否小于保护视力的健康距离的提示语音或者提示音乐，避免了因为学生每次落坐的位置偏差造成测距失效。
可选地，所述方法还包括：所述测距传感器2追踪和/或测量所述学生的头部与所述测距传感器2之间的距离是间断性工作的；所述扬声器18是间断性地发出所述单片机15提醒所述学生将眼睛离远所述书本7和/或所述作业本8的第一提示语音和/或第一提示音乐，所述测距传感器2间断性的工作时间和所述扬声器18间断性发出第一提示语音和/或第一提示音乐的工作时间是同步的。也可以设定所述单片机15比较和判断所述测距传感器2间接测量出所述学生的眼睛与所述书本7和/或所述作业本8之间的距离不小于所述学生学习保护视力的健康距离时所述扬声器18不发出提示声音，不干扰所述学生学习的思绪。
可选地，所述底座10上还安装电源，所述电源分别连接所述单片机15和所述测距传感器2和所述扬声器18并提供所述单片机15和所述测距传感器2和所述扬声器18动力；所述电源可以是蓄电池和/或电源插座，所述电源插座可以外接电源。

11、本申请提出了“所述学生家长通过所述智能手机3或者所述电脑29获得所述单片机15报告的所述学生的眼睛与所述书本7和/或所述作业本8的距离小于保护视力健康距离的时长和/或被间断性测量的次数，和/或获得所述单片机15报告的所述学生学习的环境光亮测量是否符合环境光亮强弱的标准”的技术方案。学生年龄小，学生对年幼时或者年轻时视力损伤以后给自己今后的人生可能造成严重性的后果认识不足，学生对看书或/和做作业时不健康的用眼习惯可能造成永久性损伤视力的认识严重不足，学生对持之以恒地保持良好的健康用眼习惯看书、做作业的自觉性严重不足。小孩子天生是不会主动地严格健康用眼的，现实生活中是有一部分学生家长在一而再、再而三地提醒和督促自己的孩子如何保持健康用眼，但是，并不是所有的学生家长都能够认识到这个问题，很多学生的家长工作繁忙，更有很多农村的学生家长在异国他乡务工的现实情况，很多学生的家长并没有充足的时间和精力监控和督促自己的孩子保持健康用眼，尤其是学生看书和看着作业本做作业的时间基本上都是在家中，学校的老师又管不到，这是现在视力不良的学生很多的原因所在，也是社会上患病近视眼的人很多的原因所在。因为如果 小孩子在刚开始学习的时候没有能够得到有效的监控和督促形成健康用眼的习惯，那么在学生时代已经损伤眼睛了，或者不健康的用眼习惯也会不可避免地使他在成年以后的学习或者工作或者游戏或者生活中眼睛受到损伤而患病近视眼。很多人在学生时代就开始的视力减退的很重要的一个原因是缺乏有效监控和督促学生健康用眼的装置和方法，学生学习健康用眼主要是在学生学习时要保持眼睛距离书本或/和作业本在健康的距离和在学习的间隙当中经常性地做锻炼眼睛的活动和学生学习环境的光亮强弱要合适的三个要素，这些都是要持之以恒地监控和督促，学生才可能逐渐地养成习惯的，即使有比较好的认知的家长对自己的孩子监控和督促往往也是力不从心的或者是不能保证在这三个方面都一定是能够做好了的。本实施例的一种学生学习保护视力的桌面装置和方法部分代劳了学生家长不可或缺的监控和督促各个同学在家学习的时间内持之以恒地健康用眼的工作，比较各位学生家长的监控和督促有耐心、持之以恒、要求标准统一、成本低、效果好、容易普及推广，特别是方法得体，能够激发学生保护视力健康用眼的积极性，所述桌面装置和方法针对性强、达到的应用效果好。推广本申请一种学生学习保护视力的桌面装置和方法的技术方案可以很容易地使学生从小学生开始就养成一辈子健康用眼保护视力的良好习惯保持视力健康，也使得所述学生终身受益匪浅。
12、“所述学生或者所述学生的家长触发操作所述智能手机3或者所述电脑29上网私人定制所述学生偶像的语音或老师的语音或其它的声音作为所述扬声器18发出提醒的第一提示语音和/或第一提示音乐范本传送给所述单片机15存储，或所述单片机15通过所述扬声器18发出提醒的第一提示语音是所述单片机15报告的累积的所述学生的眼睛与所述书本7和/或所述作业本8的距离小于保护视力健康距离的时长和/或被间断性测量的次数”的技术方案，或者是偶像的语音或者是老师的语音对于一部分学生具有亲和力、具有号召力，一部分学生心理上容易接受这样的监控和督促，有这样兴趣的同学对这样的提示不乏、不腻没有抵触情绪，或者是提示累积的测量结果具有约束力使得学生容易接受提示。
13、所述测距传感器2和所述光敏传感器17的测量结果上传云存储，所述学生获得上传云存储以后关于保护视力行为的评估和建议的反馈，使得学生和家长都能够及时地获得使用一种学生学习保护视力的装置和方法效果的科学评估和进一步健康用眼科学的建议。
14、分析患近视眼病的时间主要发生在人生的两个阶段，第一个阶段是在学生时代没有得到很好的保护视力健康用眼的教育和有效的监控督促，第二个阶段是在成年了走上工作岗位以后没有良好的健康用眼的习惯保护好眼睛，这两个阶段是有完全不同的特征。本申请实施例的技术方案是针对学生学习阶段监控和督促学生健康用眼有利于学生在学生学习阶段就保持眼睛健康，特别是使学生在多年学习阶段的监控和督促下也形成了良好的健康用眼习惯。本技术方案针对性强地从小孩子的身体发育和小孩子接受知识教育的人生的两个出发点附近就开始主动地实施的培养学生养成健康用眼的良好习惯的技术方案，比较于现有技术针对玩手机、玩游戏、看电视或在电脑前面长时间工作而设计的健康用眼的一些技术方案，从方案实施时机来看和从方案针对的实施对象及达到的实施效果来看，本申请技术方案都是一种好得多的保护视力的技术方案，尤其是学生在多年学习阶段的如此监控和督促下也形成了良好的健康用眼习惯减少了所述学生成年以后在工作和/或娱乐过程中患近视眼病的可能性，本申请实施例的技术方案比较现有技术的保护视力的技术方案是一种事半功倍的技术方案。
15、本发明提供的一种学生学习保护视力的方法，尤其是适合学生在家学习保护视力健康用眼的一种桌面装置，部分代劳了学生家长监控和督促学生在家学习时健康用眼的工作。学生在学校学习的大部分时间是听老师讲课和看老师在黑板上的板书，学生在家学习的大部分时间要么是看书要么是看着作业本做作业，学生后天性患病近视眼的大多数的原因是学生的眼睛习惯性地近距离的看书造成的，现有大部分患病近视眼的学生都是由于学生在家学习时近距离地看书或者近距离的看着作业本做作业的不健康用眼造成的，本申请实施例适合学生在家学习看书或者是看着作业本做作业的一种学生学 习保护视力的桌面装置和方法的技术方案比较于在其它场景下实施的现有技术具有学生保护视力的有益的技术效果和显著的进步。虽然本申请实施例提供的桌面装置和方法更为适合学生在家学习时使用，但并不是说本申请实施例提供的桌面装置和方法只能在学生在家学习时使用，学生在其他场景中学习时也可以使用本申请实施例提供的桌面装置和方法。
本申请的技术方案是现有技术所没有的，具有实用性，具有新颖性，具有创造性。
最后应说明的是：以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
