游泳帽及游泳提示方法 技术领域
本申请涉及一种游泳用具，尤其涉及一种游泳帽及游泳提示方法。
背景技术
目前，现在的游泳帽，为了防止游泳特别是潜泳时撞到游泳池的池壁，通常是在游泳帽上增加防护结构，来保护头部，例如在帽顶处进行增厚。另外，对于盲人游泳来说，为了防止盲人撞上游泳池的池壁，现在通常是有他人通过在边上通过引导棒进行引导。然而，这些方式，要么是在已经发生碰撞后的保护，要么需要他人协助来防止碰撞，无法满足单人游泳时提前避免碰撞的需求。
发明内容
本申请实施例公开一种游泳帽及游泳提示方法，能够在单人游泳时提前进行提示，避免碰撞。
本申请实施例公开一种游泳帽，所述游泳帽包括距离传感器、输出单元和控制器。所述距离传感器用于感测游泳帽外侧的目标物体与游泳帽之间的距离。所述控制器用于在距离传感器感测的距离小于或等于预设距离时，控制输出单元产生提示信号。
本申请实施例还公开一种游泳提示方法，应用于一游泳帽中，所述游泳提示方法包括：通过游泳帽中的距离传感器感测游泳帽外侧的目标物体与游泳帽之间的距离；以及在距离传感器感测的距离小于或等于预设距离时，控制输出单元产生提示信号。
本申请的游泳帽和游泳提示方法，当用户头戴游泳帽进行游泳时，通过距离传感器感测游泳帽外侧的目标物体和游泳帽之间的距离，并在感测的距离小于或等于预设距离时，控制输出单元产生提示信号，能够在触碰到目标物体之前提醒用户进行回避或转身，用户可独自进行游泳而避免碰撞到游泳池的池壁等目标物体。
附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本申请一实施例中的游泳帽的功能模块图
图2为本申请一实施例中的输出单元的示意图。
图3为本申请另一实施例中的输出单元的示意图。
图4为本申请再一实施例中的输出单元的示意图。
图5为本申请一实施例中的游泳帽的结构示意图。
图6为本申请一实施例中的游泳提示方法的流程图。
图7为本申请另一实施例中的游泳提示方法的流程图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，为本申请一实施例中的游泳帽100的功能模块图。所述游泳帽100包括距离传感器1、输出单元2以及控制器3。所述距离传感器1用于感测游泳帽100外侧的目标物体与游泳帽100之间的距离。所述控制器3用于在距离传感器1感测的距离小于或等于预设距离时，控制输出单元2产生提示信号。
从而，本申请中，当用户头戴游泳帽100进行游泳时，通过距离传感器1感测游泳帽100外侧的目标物体和游泳帽100之间的距离，并在感测的距离小于或等于预设距离时，控制输出单元2产生提示信号，能够在触碰到目标物体之前提醒用户进行回避或转身，用户可独自进行游泳而避免碰撞到游泳池的池 壁等目标物体。
所述游泳帽100还包括压力传感器4，用于感测游泳帽100的外侧压力。所述控制器3还用于在所述压力传感器4感测到的压力大于或等于预设压力时，控制所述距离传感器1启动而感测游泳帽100外侧的目标物体与游泳帽100之间的距离。
所述控制器3还用于在所述压力传感器4感测到的压力小于所述预设压力时，控制所述距离传感器1关闭。
从而，本申请中，在压力传感器4感测到的压力大于或等于预设压力时才控制距离传感器1启动，从而，可以在确保用户是在泳池中进行游泳时受到了水的压力时才启动距离传感器1，在压力小于预设压力时，说明此时用户的头部并未进入水中，此时可控制距离传感器1关闭，避免了距离传感器1一直开启，节省了电能。
在一些实施例中，所述控制器3在距离传感器1感测的距离小于或等于预设距离时，控制输出单元2产生提示信号，可具体包括：所述控制器3在距离传感器1感测的距离小于或等于第一预设距离时，控制输出单元2产生第一提示信号，以及在距离传感器1感测的距离小于或等于第二预设距离时，控制输出单元2产生第二提示信号，其中，所述第二预设距离小于第一预设距离。
从而，通过分阶段多次提醒，能够有效提醒用户注意。
在一些实施例中，所述第一预设距离可为8米，所述第二预设距离可为5米。显然，在其他实施例中，所述第一预设距离和第二预设距离也可为其他合适的值，例如所述第一预设距离可为6米，第二预设距离可为3米，等等。
显然，在一些实施例中，也可仅提醒一次，即，所述预设距离为5米，所述控制器3在距离传感器1感测的距离小于或等于预设距离，例如5米时，控制输出单元2产生提示信号。
在一些实施例中，所述控制输出单元2产生提示信息的时长可以持续预设时间，例如，当产生一次提示信息时，提示信息可以持续5秒，当产生两次提示信息时，第一提示信息、第二提示信号可以持续5秒，或者，第一提示信息可以在所述距离传感器1感测的距离位于第一预设距离和第二预设距离之间时一直持续产生，从而，通过较长时间产生提示信息，可以有效提醒用户注意。
请一并参阅图2，为一实施例中的输出单元2的示意图，如图2所示，所述输出单元包括振动器21，所述第一提示信号为具有第一强度的振动提示信号，所述第二提示信号为具有第二强度的振动提示信号，所述第二强度大于第一强度。其中，所述振动器21为蜂鸣器等。
从而，在距离传感器1感测的距离小于或等于第一预设距离但大于第二距离时，振动器21产生较低强度的振动提示信号，而随着更靠近目标物体，即，在距离传感器1感测的距离小于或等于第二预设距离时，振动器21将产生更高强度的振动提示信号，从而给予用户更强烈的提醒。
请参阅图3，为另一实施例中的输出单元2的示意图。所述输出单元2包括声音输出单元22，所述第一提示信号为具有第一音量的声音提示信号，所述第二提示信号为具有第二音量的声音提示信号，所述第二音量大于所述第一音量。
从而，在距离传感器1感测的距离小于或等于第一预设距离且大于第二预设距离时，振动器21产生较低音量的声音提示信号，而随着更靠近目标物体，即，在距离传感器1感测的距离小于或等于第二预设距离时，振动器21将产生更高音量的声音提示信号，从而给予用户更强烈的提醒。
其中，所述声音提示信号可为简单的滴滴声、嘟嘟声等声音，也可为包括预设语音内容的声音提示信号，例如，可为包括“请注意前方有障碍物”的语音内容的声音提示信号。
其中，所述声音输出单元22可为扬声器等声音输出器件。
请参阅图4，为再一实施例中的输出单元2的示意图。在再一实施例中，输出单元2可同时包括振动器21和声音输出单元22。所述第一提示信号可同时包括具有第一强度的振动提示信号和具有第一音量的声音提示信号，所述第二提示信号可同时包括具有第二强度的振动提示信号和具有第二音量的声音提示信号。
从而，通过同时产生振动提示信号和声音提示信号，可更加确保能够提醒到用户，提高了提醒的成功率。
在一些实施例中，所述距离传感器1为超声波传感器，用于向游泳帽的外侧发射超声波信号，并根据反射回来的超声波信号确定游泳帽外侧的目标物体 与游泳帽之间的距离。
具体的，所述距离传感器1根据接收到反射回来的超声波信号与发射所述超声波信号的时间差以及超声波信号的传播速度确定游泳帽100外侧的目标物体与游泳帽100之间的距离。
例如，设超声波信号的传播速度为v，接收到反射回来的超声波信号与发射所述超声波信号的时间差为t，则目标物体与游泳帽100之间的距离d＝v*t/2。
其中，由于游泳帽100的尺寸一般远小于目标物体与游泳帽100之间，因此，无论距离传感器3设置于游泳帽100的哪个位置，通过距离传感器1感测的距离均可视为用户的头部与目标物体之间的距离，从而，通过距离传感器1去感测距离，而产生相应的提示信号，能够在用户游泳时头部处于相应的距离范围时产生相应的提示。

其中，所述电源开关6可为MOS管Q1，MOS管Q1的漏极和源极分别与电源5和距离传感器1电连接，MOS管Q1的栅极与控制器3连接，所述控制器3用于输出相应的电平信号而控制MOS管Q1导通或断开。例如，所述MOS管Q1可为NMOS管，所述控制器3在所述压力传感器4感测到的压力大于或等于预设压力时，输出高电平信号至MOS管Q1的栅极，而控制MOS管Q1导通，所述控制器3在所述压力传感器4感测到的压力小于预设压力时，输出低电平信号至MOS管Q1的栅极，而控制MOS管Q1断开。
