Description

过街音响提示方法及系统 技术领域
本申请涉及智能出行的技术领域，尤其是涉及一种过街音响提示方法及系统。
背景技术
人行横道两端路口处设置有用于过街提示的信号灯，考虑到视障人士的出行，部分信号灯通过安装发声装置为视障人士提供过街通行的声音指引，为视障人士的出行带来便利。
但持续的声音播报，对周边环境带来较大的噪声干扰；易受到群众投诉而被迫降低发声装置播报的音量或关停，如何安全通过人行横道的问题仍给视障人士带来较大困扰，需要进行改进。
发明内容
为了在实现降低盲人过街音响提示装置对外界的影响，方便视障人士安全地通过人行横道，本申请提供了一种过街音响提示方法、系统、智能过街音响提示装置、移动终端、云平台以及介质。
本申请公开一种过街音响提示方法，包括步骤：
当提示装置接收到来自移动终端的包括代表视障人士的触发消息时，提示装置播报与该提示装置预先关联的信号灯状态的第一类信息。
通过采用上述技术方案，视障人士出行时随身携带移动终端，移动终端通过蓝牙等无线通信的方式发送触发消息，当移动终端靠近位于路口处的人行横道信号灯时，提示装置即能接收到代表视障人士的触发消息，提示装置则基于与自身预先关联的信号灯当前状态的信息，即第一类信息，语音播报当前信号灯的状态。
而当移动终端未靠近路口的人行横道信号灯，提示装置不播报，因此，通过检测移动终端是否靠近提示装置且识别是否为视障人士携带的移动终端，以触发提示装置仅在视障人士靠近时进行信号灯状态的信息播报，解决提示装置持续播报带来的噪音干扰问题。
在一较佳示例中：过街音响提示方法包括步骤：当提示装置接收到来自移动终端的触发消息，则判断提示装置内置的唯一设备码是否与触发消息包含的唯一设备码一致，若是，则提示装置播报与该提示装置预先关联的信号灯状态的第一类信息。
通过在移动终端发出的触发消息中加入唯一设备码的判断条件，能够仅触发视障人士的出行路线上的提示装置进行语音播报，则视障人士身处复杂的路口处时，也仅有符合出行路线的单个提示装置进行播报，使得视障人士能够更为准确地辨认可通行的路口，方便视障人士安全地通过人行 横道。
在一较佳实施例中，执行如下步骤：当云平台接收到来自智能终端的目的地数据和定位数据时，基于目的地数据和定位数据规划出行路线并生成对应的出行路线数据；根据出行路线提取该出行路线途经的所有信号灯数据，获取与每个信号灯数据对应的提示装置的唯一设备码，每个信号灯数据对应一个提示装置；基于所获取的若干唯一设备码生成设备码列表，将设备码列表和出行路线数据发送并缓存至智能终端。
视障人士出行时，通过语音识别功能在移动终端输入前往的目的地，确认目的地后获取视障人士当前的定位数据并发送至云平台，云平台根据目的地数据和当前的定位数据规划生成出行路线，提取出行路线数据途经的信号灯数据，即能够获取到出行路线上途经的所有信号灯的位置，每个提示装置关联一个信号灯以获取信号灯的实时数据，实现获取途经的所有信号灯对应的提示装置各自的唯一设备码，即能实现视障人士携带智能终端出行时，智能终端能够匹配到出行路线上信号灯关联的提示装置。
通过在云平台预存储路网数据和道路节点数以及预存储信号灯数据和提示装置的唯一设备码，将出行路线和途经的信号灯数据对应的提示装置的唯一设备码发送至智能终端，以确保智能终端准确实时触发提示装置播报第一类信息。
在一较佳示例中，还执行如下步骤：提示装置实时向智能终端发送与该提示装置相关联的信号灯状态的第二类信息；智能终端接收并实时播报信号灯状态的第二类信息。
提示装置接收到触发消息后，提示装置将与其关联的信号灯状态的第二类信息发送至智能终端，第一类信息和第二类信息均代表信号灯的状态，区别在于第二类信息和第一类信息的状态详细程度不同，智能终端接收到第二类信息时，通过智能终端自带的读屏功能实时播报出所接收的信号灯状态第二类信息；能在视障人士通过人行横道过程中，为其播报实时的出行路线上信号灯的状态，方便视障人士了解信号灯的通行状态，同时，在较为嘈杂的户外环境下，提示装置播报的声音易被掩盖，移动终端同时播报信号灯状态信息进一步保障了视障人士能够得到通行的提示。
在一较佳示例中：每个信号灯数据预先绑定一个道路ID，根据出行路线提取该出行路线途经的所有信号灯数据的步骤，包括：云平台识别该出行路线数据，得到路口位置数据；获取每个路口位置数据中包含的信号灯数据，识别每个信号灯数据预先绑定的道路ID；识别并提取出道路ID与出行路线的道路ID一致的信号灯数据。
出行路线由多个道路组成，而路口处每个信号灯对应一个道路ID，通 过道路ID能够准确地识别与出行路线一致的路段，再获取所识别出的道路ID绑定的信号灯数据，使得途经的信号灯数据获取方式更为准确和方便，进而使提示装置的唯一设备码获取更为准确。
在一较佳示例中，执行如下步骤：该播报第一类信息的提示装置发出预设置的配对请求消息；该播报第一类信息的提示装置周围的提示装置识别该配对请求消息，并判断是否与该播报第一类信息的提示装置为配对关系，若是，则开始播报所关联信号灯状态的第一类信息。
当视障人士在通过人行横道时，随着视障人士逐渐远离出发路口处的信号灯，对视障人士而言，出发点的提示装置播报的声音逐渐减弱，而通过设置两个提示装置之间的配对关系，使得同一人行横道两端路口处的信号灯关联的提示装置均播报信号灯状态的第一类信息，进而视障人士在通过人行横道的过程中均能够较为清晰地接收到提示装置播报的第一类信息。
本申请还提供智能过街音响提示装置，智能过街音响提示装置包括检测模块、蓝牙通信模块、远程通信模块、发声模块以及嵌入式处理器；检测模块用于实时采集与该智能过街音响提示装置关联的人行横道信号灯状态的第一类信息并发送至嵌入式处理器；嵌入式处理器与发声模块电连接以用于将第一类信息发送至发声模块，发声模块用于播报第一类信息；蓝牙通信模块用于与移动终端通信以接收来自移动终端的包括代表视障人士的触发消息；远程通信模块用于与云平台通信以接收云平台发送的代表人行横道信号灯状态的第一类信息的音频数据包。

视障人士在忘记携带移动终端出门的情况下，通过设置在信号灯处的 按键模块，能够让发声模块播报信号灯状态的第一类信息，使得视障人士出行更加便利，由于现有信号灯的信号获取需从信号灯的信号控制机处获取，而智能过街音响提示装置安装在信号灯处，需要拉设长电线至信号机处才能够获取到信号灯状态的第一类信息，通过对信号灯通电信号变化的检测，方便了信号灯状态的第一类信息的获取。蓝牙通信模块将第二类信息发送至智能终端，以使智能终端与提示装置同时播报信号灯的状态，进而在路况嘈杂的情况下，视障人士能够通过智能终端更为清晰获知信号灯状态，远程通信模块通过将智能过街音响提示装置的使用情况数据发送至云平台，使得工作人员能够获知智能过街音响提示装置的播报频次，进而能够获知视障人士的出行习惯以及提示装置是否出现故障等。

在本实施例中，提示装置的唯一设备码由工作人员通过云平台预先赋予，每个提示装置对应一个唯一设备码，唯一设备码为数字编码或自定义的名称、例如数字编码“001、002、003”。
云平台创建有用于存储路网数据和道路节点数据的云端地图数据库、创建有用于存储信号灯数据和提示装置的唯一设备码的信号灯信息数据库，创建有用于存储音频数据包的云端语音数据库；云端地图数据库存储为某市或某区的路网数据和道路节点数据，不同市或区之间存储的路网数据和道路节点数据不同。
信号灯数据包括信号灯的位置数据、信号灯对应提示的道路ID以及该信号灯的配置数据，配置数据包括信号灯亮灭的时长和切换规律；信号灯数据是指出行路线上途经的信号灯。
具体的，云平台基于目的地数据和定位数据生成从定位处到达目的地的出行路线数据。优选的，若从定位处到达目的地包括了多种出行路线，则根据预设筛选规则筛选出耗时最短、信号灯数量最少或路程最短的出行路线最为最优的一个出行路线数据。预设筛选规则可切换以得到不同类型的最优出行路线数据。
进一步的，提取所生成的出行路线数据途经的信号灯数据，以得到出行路线上途经的所有信号灯的数据，进一步获取所提取的信号灯数据对应的提示装置的唯一设备码，将出行路线途经的所有信号灯的提示装置的唯一设备码、以及出行路线数据发送并缓存至智能终端，其中，出行路线数据展示在智能终端的导航APP界面。
S50：当提示装置接收到来自移动终端的触发消息，则判断提示装置内置的唯一设备码是否与触发消息包含的唯一设备码一致，若一致，则提示装置播报与该提示装置预先关联的信号灯状态的第一类信息。
本实施例中，若提示装置接收到来自移动终端的触发消息包含了唯一设备码，则该移动终端为具有定位导航功能的智能终端。
具体的，当智能终端发出的触发消息中包含唯一设备码的判断条件时，判断提示装置预先缓存的唯一设备码是否与触发消息包含的唯一设备码一致，即判断提示装置的唯一设备码是否在智能终端缓存的设备码列表中，若是，则提示装置播报与该提示装置预先关联的信号灯状态的第一类信息。
参照图5，某十字路口处设置有8个信号灯，每个信号灯均安装有8个提示装置，分别为装置A、装置B、装置C、装置D、装置E、装置F以及装置G，通过人行横道时，基于道路ID提取的信号灯数据则为装置A对应的信号灯数据和装置B对应的信号灯数据，则视障人士在经过此路口时， 由靠近智能终端的装置A先播报信号灯状态的第一类信息，当智能终端靠近装置B时，装置B播报信号灯状态的第一类信息，此过程中其他剩余的提示装置均不播报。

在本实施例中，路口位置数据是指出行路线中途经的每一个路口的数据，信号灯数据预先绑定的道路ID，是指该信号灯用于提示的道路的某一路段。
具体的，获取出行路线上途经的所有路口的路口位置数据，获取每个路口位置数据的信号灯数据，进一步获取每一个路口位置数据包含的信号灯数据，并识别每个信号灯数据对应的道路ID，即能获取到每个信号灯对应提示的道路路段，进一步识别道路ID与出行路线的道路路段一致的信号灯数据。
参照图7，此时视障人士通过图5中的人行横道后，根据出行路线再次通过图7中的又一人行横道，此时识别信号灯数据预先绑定的道路ID，提取的信号灯数据则为装置C对应的信号灯数据和装置D对应的信号灯数据，由靠近智能终端的装置C先播报信号灯状态的第一类信息，当智能终端靠近装置D时，装置D播报信号灯状态的第一类信息，此过程中其他剩余的提示装置均不播报。
进一步的，第一类信息还包括了信号灯对应的道路ID，因此提示装置播报第一类信息时，例如，“横过北京路，绿灯、滴、滴、滴”，而当该信号灯的状态数据为绿灯切换为红灯时，则对应的音频数据包为“横过北京路，红灯、嘟、嘟、嘟”。
示例：参照图8和图9，视障人士11通过智能终端13的APP导航界面，开启读屏功能，语音识别输入目的地信息为北京路，即得到若干检索信息，通过读屏功能完成检索信息的选择后，将被选择的检索信息作为目的地数据。
完成目的地数据的选择后，云平台14计算得到出行路线数据，并提取出行路线数据途经的信号灯数据，获取信号灯数据对应的提示装置16的唯一设备码，云平台14将出行路线数据和唯一设备码发送至智能终端13，智能终端13的APP跳转至导航界面，参照图10，光标所在位置即为移动 终端当前定位，图中若干箭头所示方向即为出行路线。
参照图9，当视障人士11处到达某路口需通过人行横道时，此时路口处的位于出行路线上的信号灯15关联的提示装置16接收到视障人士11携带的智能终端13发出的触发信号，提示装置16获取到目前信号灯15的状态为红灯，进一步提示装置16播报“横过某某路段，红灯，嘟、嘟、嘟”，当红灯切换为绿灯时，提示装置16播报“横过某某路段，绿灯，滴、滴、滴”。
当视障人士11出行使得智能穿戴式设备12时，智能穿戴式设备12靠近路口处的信号灯15关联的提示装置16时，向提示装置16发出触发消息以使提示装置16播报关联的信号灯15的第一类信息。

在实施例2的步骤S50之后，还执行如下步骤：
S60：提示装置实时向智能终端发送与该提示装置相关联的信号灯状态的第二类信息；
S70：智能终端接收并实时播报信号灯状态的第二类信息。
在本实施例中，第一类信息和第二类信息均为代表信号灯状态的文本数据，区别在于第二类信息和第一类信息的文本数据不同，例如第二类信息所反映的信号灯的状态比第一类信息详细，例如智能终端接收到提示装置发出的第二类信息为“某某路段、当前红灯剩余30秒，请注意安全”，同时根据出行路线数据播报道路夹角为偏左5度以及距离目的地的距离。
而第一类信息未播报信号灯剩余时间，智能终辅助播报信号灯状态信息，使得信号灯状态的播报更为具体和高频，对视障人士的提示效果更好。
具体的，参照图9，提示装置16接收到触发消息后，提示装置16将与其关联的信号灯15状态的第二类信息发送至智能终端13，智能终端13接收到信号灯15状态的第二类信息后，由于第二类信息为文本数据，采用智能终端13自带的读屏功能进行读屏并播报第二类信息，IOS系统可打开旁白功能，安卓系统可打开无障碍的talkback功能。

S40：该播报第一类信息的提示装置发出预设置的配对请求消息；
S50：该播报第一类信息的提示装置周围的提示装置识别该配对请求消息，并判断是否与该播报第一类信息的提示装置为配对关系，若是，则开始播报所关联信号灯状态的第一类信息。
在本实施例中，配对关系是指两个提示装置的唯一设备码预先设置了映射关系，即同一人行横道上的两个或两个以上的信号灯关联的提示装置的具有配对关系。
具体的，当视障人士在通过人行横道时，随着视障人士逐渐远离出发路口处的信号灯，对视障人士而言，出发点的提示装置播报的声音逐渐减弱，而通过设置配对编码进行两个提示装置之间的配对关系，使得同一人行横道两端路口处的信号灯关联的提示装置均播报信号灯状态的第一类信息，进而视障人士在通过人行横道的过程中均能够较为清晰地接收到提示装置播报的第一类信息。
参照图11，视障人士欲通过的人行横道两端的智能过街音响提示装置分别为装置A和装置B，且装置A与装置B为配对关系，当装置A开始播报关联的信号灯状态的第一类信息时，装置B接收到装置A发出的配对请求消息后开始播报所关联信号灯状态的第一类信息。
