Description

一种在飞机上测量高度的方法及设备
本申请要求于2019年09月24日提交国家知识产权局、申请号为201910905161.8、申请名称为“一种在飞机上测量高度的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种在飞机上测量高度的方法及设备。
背景技术
很多可穿戴设备，比如各类运动手表类产品，都有“高度计”功能，即可以在设备上显示设备当前的海拔高度。如图1，智能手表上有“高度计”功能，显示了智能手表当前的海拔高度为121米。
一般来说，可穿戴设备通过气压传感器实现“高度计”功能。大气压是随着海拔高度变化的，压高公式描述了大气压随海拔高度变化的规律。可穿戴设备可以根据气压传感器测量到的气压值和压高公式计算出当前的海拔高度。
但是，在一些情况下，可穿戴设备所处环境的气压并不是大气压。比如，用户佩戴可穿戴设备乘坐飞机时，由于飞机的座舱会增压，气压传感器测量到的气压值并不是当前海拔高度对应的大气压值。可穿戴设备根据气压传感器测量到的气压值和压高公式计算出的高度值，并不是可穿戴设备所处的真实海拔高度；即可穿戴设备的气压传感器的数据在这种情况下是不可信的，可穿戴设备的“高度计”功能失效。例如，用户佩戴智能手表乘坐飞机时，飞机已经飞上近万米的高空，而智能手表显示的海拔高度仅为2000米左右。
发明内容
本申请实施例提供一种在飞机上测量高度的方法及设备，可以实现在用户乘坐飞机等情况下，气压传感器的数据不可信时，可穿戴设备等电子设备能够显示准确的海拔高度。
第一方面，本申请实施例提供一种在飞机上测量高度的方法，该方法可以包括：电子设备显示根据第一检测方式获取的海拔高度；确定满足第一切换条件，该电子设备显示根据第二检测方式获取的海拔高度。
在该方法中，电子设备可以根据所处的环境等条件，切换获取海拔高度的检测方式。这样，当一种检测方式失效时，可以切换另一种检测方式，使得电子设备显示准确的海拔高度。
在一种可能的设计中，第一切换条件包括：电子设备根据第一检测方式获取的数据失效。也就是说，当第一检测方式失效时，根据第一检测方式获取的海拔高度是不准确的，电子设备由显示根据第一检测方式获取的海拔高度，切换为显示根据第二检测方式获取的海拔高度，则可以显示准确的海拔高度。
在一种可能的设计中，如果确定在第一预设时长内，电子设备的海拔高度值增加的数值大于预设的第一高度阈值；则确定根据第一检测方式获取的数据失效。
在该方式中，确定在第一预设时长内，电子设备的海拔高度值增加的数值大于预设的 第一高度阈值，则可以确定用户佩戴该电子设备乘坐的飞机起飞。飞机起飞后，飞机座舱加压，则根据第一检测方式获取的数据失效。
在一种可能的设计中，电子设备显示根据第二检测方式获取的海拔高度时，如果确定满足第二切换条件，电子设备显示根据第一检测方式获取的海拔高度。
在该方法中，电子设备可以根据所处的环境等条件，切换回显示根据第一检测方式获取的海拔高度。
在一种可能的设计中，第二切换条件包括：电子设备根据第一检测方式获取的数据恢复有效。也就是说，当第一检测方式恢复有效时，根据第一检测方式获取的海拔高度是准确的，电子设备由显示根据第二检测方式获取的海拔高度，切换为显示根据第一检测方式获取的海拔高度。在一些场景中，比如，第一检测方式获取的海拔高度更精确，电子设备及时地切换回显示根据第一检测方式获取的海拔高度，则可以使得电子设备显示的海拔高度值更精确。比如，第二检测方式比较耗电，电子设备及时地切换回显示根据第一检测方式获取的海拔高度，可以降低耗电量。
在一种可能的设计中，如果确定根据第一检测方式获取的海拔高度，与根据第二检测方式获取的海拔高度之间的差值的绝对值小于预设阈值，则说明根据第一检测方式获取的海拔高度是准确的，可以确定根据第一检测方式获取的数据恢复有效。
在一种可能的设计中，如果确定在第二预设时长内，电子设备的海拔高度值减小的数值大于预设的第二高度阈值，则说明用户佩戴电子设备乘坐的飞机降落，可以确定根据第一检测方式获取的数据恢复有效。
在一种可能的设计中，第二切换条件包括：电子设备检测到用户关闭第二检测方式的操作。用户关闭了第二检测方式，则电子设备不能通过第二检测方式获取海拔高度，电子设备由显示根据第二检测方式获取的海拔高度，切换为显示根据第一检测方式获取的海拔高度。
在一种可能的设计中，第一检测方式为通过气压传感器检测电子设备的海拔高度；第二检测方式为接收GNSS数据中的海拔高度数据，获取电子设备的海拔高度。
在一种可能的设计中，电子设备显示根据第二检测方式获取的海拔高度之前，开启电子设备的GNSS功能。电子设备开启了GNSS功能，才可以接收GNSS数据中的海拔高度数据，从而获取电子设备的海拔高度，并显示海拔高度。
在一种可能的设计中，电子设备按照预设的第一时间间隔，周期性的打开电子设备的GNSS功能。由于GNSS功能的功耗较大，相比一直打开GNSS功能，这种按照时间间隔周期性的打开GNSS功能的方法，可以有效降低耗电量。
第二方面，本申请实施例提供一种电子设备，该电子设备可以实现第一方面所述的在飞机上测量高度的方法。该电子设备可以通过软件、硬件、或者通过硬件执行相应的软件实现上述方法。

在一种可能的设计中，该电子设备可以包括：处理模块，显示模块，第一检测模块和 第二检测模块。其中，显示模块用于显示第一检测模块获取的海拔高度；还用于显示第二检测模块获取的海拔高度；处理模块用于确定是否满足第一切换条件，如果确定满足第一切换条件，则确定显示模块显示第二检测模块获取的海拔高度。
在一种可能的设计中，第一切换条件包括：第一检测模块获取的数据失效。
在一种可能的设计中，第一检测模块获取的数据失效包括：处理模块确定在第一预设时长内，电子设备的海拔高度值增加的数值大于预设的第一高度阈值。
在一种可能的设计中，处理模块还用于确定是否满足第二切换条件，如果确定满足第二切换条件，则确定显示模块显示第一检测模块获取的海拔高度。
在一种可能的设计中，第二切换条件包括：第一检测模块获取的数据恢复有效。
在一种可能的设计中，第一检测模块获取的数据恢复有效包括：处理模块确定第一检测模块获取的海拔高度，与第二检测模块获取的海拔高度之间的差值的绝对值小于预设阈值。
在一种可能的设计中，第一检测模块获取的数据恢复有效包括：处理模块确定在第二预设时长内，电子设备的海拔高度值减小的数值大于预设的第二高度阈值。
在一种可能的设计中，第二切换条件包括：处理模块确定检测到用户关闭第二检测模块的检测方式的操作。
在一种可能的设计中，第一检测模块为气压传感器，第二检测模块为GNSS模块。
在一种可能的设计中，处理模块还用于确定开启GNSS模块的GNSS功能。
在一种可能的设计中，处理模块还用于确定GNSS模块按照预设的第一时间间隔，周期性的打开GNSS功能。
第三方面，本申请实施例提供一种计算机存储介质，该计算机存储介质包括计算机指令，当所述计算机指令在电子设备上运行时，使得电子设备执行如第一方面及其可能的设计方式所述的在飞机上测量高度的方法。
第四方面，本申请实施例提供一种计算机程序产品，当所述计算机程序产品在计算机上运行时，使得所述计算机执行如第一方面及其可能的设计方式所述的在飞机上测量高度的方法。

处理器110可以包括一个或多个处理器，例如：处理器110可以包括应用处理器，控制器，数字信号处理器(digital signal processor，DSP)等。其中，不同的处理器可以是独立的器件，也可以集成在一个或多个处理器中。
其中，控制器可以是电子设备100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
应用处理器上可以安装有电子设备100的操作系统，用于管理电子设备100的硬件与软件资源。比如，管理与配置内存、决定系统资源供需的优先次序、控制输入与输出设备、操作网络、管理文件系统、管理驱动程序等。操作系统也可以用于提供一个让用户与系统交互的操作界面。其中，操作系统内可以安装各类软件，比如，驱动程序，应用程序(application，App)等。
存储器120，用于存储指令和数据。在一些实施例中，存储器120为高速缓冲存储器。该存储器可以保存处理器110使用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从存储器120中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
在一些实施例中，存储器120也可以设置于处理器110中，即处理器110包括存储器120。本申请实施例对此不进行限定。
显示屏130，用于显示图像，视频等。显示屏130包括显示面板。显示面板可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，Miniled， MicroLed，Micro-oLed，量子点发光二极管(quantum dot light emitting diodes，QLED)等。在一些实施例中，电子设备100可以包括1个或N个显示屏130，N为大于1的正整数。
电源模块140，可以用于向电子设备100包含的各个部件供电。在一些实施例中，该电源模块140可以是电池，如可充电电池。
气压传感器150A，用于测量气压。本申请实施例中，电子设备100通过气压传感器150A测得的气压值计算海拔高度。在一种示例中，电子设备100根据气压传感器150A测得的气压值和压高公式计算海拔高度。压高公式是描述气压随高度变化规律的公式。根据气压值和压高公式计算高度的具体方法可以参考常规技术中的描述，本申请实施例在此不再赘述。
触摸传感器150B，也称“触控面板”。触摸传感器150B可以设置于显示屏130，由触摸传感器150B与显示屏130组成触摸屏，也称“触控屏”。触摸传感器150B用于检测作用于其上或附近的触摸操作。触摸传感器可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。可以通过显示屏130提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器150B也可以设置于电子设备100的表面，与显示屏130所处的位置不同。
定位模块160，用于定位电子设备100。本申请实施例中，定位模块160可以接收全球导航卫星系统(global navigation satellite system，GNSS)的数据，GNSS的数据包括平面经纬度、海拔高度等。电子设备100可以通过GNSS的海拔高度数据获取其海拔高度。其中，所述GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)，伽利略卫星导航系统(galileo satellite navigation system，GSNS)和/或星基增强系统(satellite based augmentation systems，SBAS)。
本申请实施例提供的在飞机上测量高度的方法，可以应用于上述电子设备100。电子设备100具有“高度计”功能，可以在显示屏130上显示电子设备100的当前海拔高度。电子设备100可以通过气压传感器150A测得的气压值获取电子设备100的海拔高度；电子设备100也可以通过定位模块160接收的海拔高度数据获取电子设备100的海拔高度。通常情况下，由于通过气压传感器测得的气压值获取的海拔高度，比电子设备接收GNSS的数据获取的海拔高度更精确，显示屏130上显示的高度值为通过气压传感器150A获取到的海拔高度。当电子设备100确定通过气压传感器150A获取的海拔高度数据不可信时，显示屏130上显示定位模块160接收的海拔高度。这样，在用户乘坐飞机等情况下，气压传感器的数据不可信时，电子设备100也可以显示准确的海拔高度。当然，电子设备100在显示屏130上显示当前海拔高度的功能也可以是其他名称，电子设备100在显示屏130上并不显示“高度计”字样。比如，电子设备100的显示屏130上显示“海拔高度：XX米”等。
在一些实施例中，上述电子设备100的气压传感器和/或定位模块可以不设置在该电子设备100上，即电子设备100可以借助与其连接的其他设备(电子设备200)的气压传感器和/或定位模块获取当前海拔高度，并在电子设备100上进行显示。
在一种示例中，如图2B，电子设备100和电子设备200通过无线连接。电子设备100 包括处理器110，存储器120，显示屏130，电源模块140，传感器模块150等；电子设备200包括定位模块210，定位模块210可以接收GNSS的数据。电子设备100可以通过传感器模块150的气压传感器150A测得的气压值获取电子设备100的海拔高度；也可以接收电子设备200的定位模块210的海拔高度数据，获取电子设备200的海拔高度，即获取到电子设备100的海拔高度。
在另一种示例中，如图2C，电子设备100和电子设备200通过无线连接。电子设备100包括处理器110，存储器120，显示屏130，电源模块140，定位模块160等；电子设备200包括传感器模块220，传感器模块220包括气压传感器220A，用于测量气压。电子设备100可以通过定位模块160接收的海拔高度数据获取到电子设备100的海拔高度；也可以接收电子设备200的传感器模块220的气压传感器220A的气压值数据，根据接收的气压值数据获取电子设备200的海拔高度，即获取到电子设备100的海拔高度。
在又一种示例中，如图2D，电子设备100和电子设备200通过无线连接。电子设备100包括处理器110，存储器120，显示屏130，电源模块140等；电子设备200包括定位模块210，传感器模块220等，其中，传感器模块220包括气压传感器220A。定位模块210可以接收GNSS的数据；气压传感器220A用于测量气压。电子设备100可以接收电子设备200的传感器模块220的气压传感器220A的气压值数据，根据接收的气压值数据获取电子设备200的海拔高度，即获取到电子设备100的海拔高度；也可以接收电子设备200的定位模块210的海拔高度数据，获取电子设备200的海拔高度，即获取到电子设备100的海拔高度。
示例性的，电子设备100为智能手表，电子设备200为手机；或者，电子设备100为手机，电子设备200为智能手表。
下面结合附图对本申请实施例提供的在飞机上测量高度的方法进行具体介绍。
本申请实施例以电子设备100为智能手表，智能手表包括如图2A所示的结构为例进行说明。可以理解的，本申请实施例提供的在飞机上测量高度的方法也适用于图2B、图2C或图2D中电子设备100。
如图3，本申请实施例提供的在飞机上测量高度的方法，可以包括：
S301、电子设备显示根据第一检测方式获取的海拔高度。
第一检测方式可以是电子设备默认的海拔高度检测方式。比如，第一检测方式为通过气压传感器检测海拔高度的方式。电子设备根据气压传感器测得的气压值获取当前的海拔高度。
比如，用户在未乘坐飞机时，电子设备显示根据气压传感器测得的气压值获取的当前的海拔高度。示例性的，电子设备显示如图1所示界面，当前海拔高度的值为121米。
S302、电子设备确定是否满足第一切换条件；如果确定满足第一切换条件，则执行S303，电子设备显示根据第二检测方式获取的海拔高度；如果确定不满足第一切换条件，则执行S301，电子设备显示根据第一检测方式获取的海拔高度。
其中，第一切换条件为气压传感器的数据失效。
比如，用户佩戴该电子设备乘坐飞机，飞机起飞。飞机起飞后，飞机的座舱加压，电子设备的气压传感器检测到的气压值与该电子设备所在海拔高度对应的大气压值不一致；即气压传感器的数据失效。
电子设备检测到满足第一预设条件，则确定气压传感器的数据失效。

GNSS高度子模块通知GNSS模块关闭GNSS功能，GNSS模块接收到GNSS高度子模块的关闭GNSS功能的通知后，关闭GNSS功能，不再接收GNSS的数据。
在一种实现方式中，GNSS高度子模块确定停止按照预设的第一时间间隔，周期性的打开GNSS功能。GNSS高度子模块通知GNSS模块，停止按照预设的第一时间间隔，周期性的打开GNSS功能。GNSS模块接收到GNSS高度子模块的通知后，停止按照预设的第一时间间隔，周期性的接收GNSS的数据。
本申请实施例提供的在飞机上测量高度的方法，通常情况下，电子设备显示的高度值为通过气压传感器获取到的海拔高度。当用户佩戴电子设备乘坐飞机时，电子设备确定气压传感器的数据失效，则电子设备可以打开GNSS功能，显示接收的GNSS数据中的海拔高度。这样，在用户乘坐飞机等情况下，气压传感器的数据不可信时，电子设备也可以显示准确的海拔高度。并且，电子设备可以周期性的断续打开GNSS功能，这样可以降低电子设备的功耗。
当用户乘坐飞机降落后，电子设备检测到气压传感器的数据恢复有效，则电子设备显示通过气压传感器获取到的海拔高度。由于通过气压传感器测得的气压值获取的海拔高度，比电子设备接收GNSS的数据获取的海拔高度更精确，这样，电子设备可以在用户非乘坐飞机的情况下，显示更准确的海拔高度。并且，这样，电子设备可以在用户非乘坐飞机的情况下，不打开GNSS功能，降低电子设备的功耗。
