技术领域technical field
本发明涉及终端技术领域，具体涉及一种传感器控制方法及装置。The present invention relates to the technical field of terminals, in particular to a sensor control method and device.
背景技术Background technique
目前的手机通常采用高通ADSP(Audio Digital Dignal Processor，音频数字信号处理器)架构。高通ADSP架构是指：传感器挂载在ADSP上，ADSP集中管理所有传感器，用于节省功耗。这种架构下，所有的传感器例如计步器等都和ADSP交互，然后ADSP和AP(Application Processor，应用处理器)交互。Current mobile phones generally adopt a Qualcomm ADSP (Audio Digital Digital Processor, audio digital signal processor) architecture. The Qualcomm ADSP architecture means that the sensor is mounted on the ADSP, and the ADSP centrally manages all sensors to save power consumption. Under this architecture, all sensors such as pedometers interact with ADSP, and then ADSP interacts with AP (Application Processor, application processor).
以计步器为例，当计步器检测到用户步伐的时候，就会产生中断，该中断上报给ADSP，ADSP就会响应并处理中断。其中，当AP处于休眠状态，也就是手机系统休眠的时候，ADSP会一直响应计步器的中断，也就是说ADSP会一直处于被间断唤醒的状态。这就导致，增加了ADSP的功耗。Take the pedometer as an example, when the pedometer detects the steps of the user, an interrupt will be generated, and the interrupt will be reported to ADSP, and ADSP will respond and process the interrupt. Among them, when the AP is in a dormant state, that is, when the mobile phone system is dormant, the ADSP will always respond to the interruption of the pedometer, that is to say, the ADSP will always be in a state of being woken up intermittently. This leads to increased power consumption of the ADSP.

Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
下面通过具体实施例，分别进行详细的说明。In the following, specific examples will be used to describe in detail respectively.
实施例一、Embodiment one,
请参考图1，本发明实施例提供一种传感器控制方法。Referring to FIG. 1 , an embodiment of the present invention provides a sensor control method.
本发明实施例方法用于各种终端，例如手机，平板电脑等。所述终端包括传感器和处理器。所述处理器包括：与所述传感器连接的、用于处理传感器中断的ADSP，以及与所述ADSP连接的AP。所处传感器可以包括计步器。The method in the embodiment of the present invention is applied to various terminals, such as mobile phones, tablet computers, and the like. The terminal includes a sensor and a processor. The processor includes: an ADSP connected to the sensor for processing sensor interrupts, and an AP connected to the ADSP. The location sensor may include a pedometer.
其中，AP是ARM架构的处理器，用于运行Linux+Android(安卓)系统；一般手机待机时，AP进入休眠状态，这时Android中应用程序的代码也会停止执行。Among them, the AP is a processor of ARM architecture, which is used to run the Linux+Android (Android) system; when the mobile phone is generally in standby, the AP enters a dormant state, and at this time, the code of the application program in the Android will also stop executing.
ADSP是DSP(Digital Signal Processor，数字信号处理器)的一种，用于处理音频数字信号。DSP是由大规模或超大规模集成电路芯片组成的用来完成某种信号处理任务的处理器，它是为适应高速实时信号处理任务的需要而逐渐发展起来的。ADSP is a kind of DSP (Digital Signal Processor, digital signal processor), which is used to process audio digital signals. DSP is a processor composed of large-scale or ultra-large-scale integrated circuit chips to complete certain signal processing tasks. It is gradually developed to meet the needs of high-speed real-time signal processing tasks.
计步器是通过统计步数、距离、速度、时间等数据，测算卡路里或热量消耗，用以掌控运动量，防止运动量不足，或运动过量的一种工具。计步器的工作核心就是震动传感器。The pedometer is a tool for calculating calories or calorie consumption by counting steps, distance, speed, time and other data to control the amount of exercise and prevent insufficient or excessive exercise. The core of the pedometer is the shock sensor.
传感器在检测到信号，例如计步器检测到用户步伐的时候，就会产生中断，生成中断信号；ADSP是管理传感器的处理器，用于响应传感器产生的终端，对中断信号进行处理。When the sensor detects a signal, for example, when the pedometer detects the user's steps, it will generate an interrupt and generate an interrupt signal; ADSP is a processor that manages the sensor, and is used to respond to the terminal generated by the sensor and process the interrupt signal.
当终端处于休眠状态时，ADSP也会休眠，但是，计步器等各种传感器通常不会休眠，会急需检测信号，并产生中断，一旦传感器产生中断，ADSP就会被传感器中断唤醒，并处理中断信号。When the terminal is in sleep state, ADSP will also sleep. However, various sensors such as pedometers usually do not sleep, and will urgently need to detect signals and generate interrupts. Once the sensor generates an interrupt, ADSP will be awakened by the sensor interrupt and process interrupt signal.
当传感器包括计步器时，ADSP会一直响应计步器的中断，也就是说ADSP会一直处于被间断唤醒的状态。这会大大增加ADSP的功耗。When the sensor includes a pedometer, the ADSP will always respond to the interrupt of the pedometer, that is to say, the ADSP will always be in the state of being woken up intermittently. This will greatly increase the power consumption of ADSP.
为了降低ADSP的功耗，本发明实施例提供了如图1所示的传感器控制方法，该方法可以包括：In order to reduce the power consumption of the ADSP, an embodiment of the present invention provides a sensor control method as shown in Figure 1, the method may include:
101、获取所述AP的状态。101. Acquire the status of the AP.
本文中的执行主体可以是终端，并以终端是采用Android系统的手机为例。The execution subject in this article may be a terminal, and the terminal is a mobile phone using an Android system as an example.
本步骤中，终端中的ADSP可实时获取AP的状态。AP的状态可包括休眠状态和唤醒状态两种。当AP处于休眠状态时，可以理解为系统处于休眠状态；当AP处于唤醒状态时，可以理解为系统处于唤醒状态。所述系统是指终端的操作系统，例如可以是Android(安卓)系统。In this step, the ADSP in the terminal can obtain the status of the AP in real time. The state of the AP can include two kinds of sleep state and wake-up state. When the AP is in the dormant state, it can be understood that the system is in the dormant state; when the AP is in the awake state, it can be understood that the system is in the awake state. The system refers to the operating system of the terminal, for example, it may be an Android (Android) system.
一些实施例中，AP的状态被一个休眠唤醒的标识所表示，终端可以获取AP的休眠唤醒的标识，所述标识指示所述AP处于休眠状态或是处于唤醒状态。In some embodiments, the state of the AP is represented by a dormancy and wakeup flag, and the terminal can acquire the dormancy and wakeup flag of the AP, and the flag indicates that the AP is in a dormant state or in an awake state.
102、当所述AP处于休眠状态时，关闭传感器中断。102. When the AP is in a dormant state, disable sensor interrupts.
本步骤中，当确认AP处于休眠状态时，关闭传感器中断，使传感器不再产生中断或者说不再生成中断信号。但需要说明的是，虽然关闭传感器中断，但不影响传感器正常工作，以计步器为例，计步器内部计步还在进行，仍然继续监测用户步伐数，只不过不产生中断，不唤醒ADSP。In this step, when it is confirmed that the AP is in a dormant state, the sensor interrupt is disabled, so that the sensor no longer generates an interrupt or no longer generates an interrupt signal. But it should be noted that although the sensor interrupt is turned off, it does not affect the normal operation of the sensor. Taking the pedometer as an example, the internal step counting of the pedometer is still in progress, and the user's steps are still monitored, but no interruption is generated and no wake-up is performed. ADSP.
一些实施例中，当AP处于休眠状态的时候，ADSP可以通过接口文件的形式关闭计步器中断，使计步器不再产生中断信号，那么ADSP也就不会被唤醒，这样就可以省去ADSP的功耗。In some embodiments, when the AP is in a dormant state, the ADSP can close the pedometer interrupt in the form of an interface file, so that the pedometer no longer generates an interrupt signal, so the ADSP will not be woken up, so that the ADSP power consumption.
103、当所述AP处于唤醒状态时，使能传感器中断。103. When the AP is in a wake-up state, enable a sensor interrupt.
本步骤中，当确认AP处于唤醒状态时，使能传感器中断，使传感器可以产生中断或者说可以生成中断信号，从而，可以唤醒ADSP来响应并处理中断。In this step, when it is confirmed that the AP is in the wake-up state, the sensor interrupt is enabled so that the sensor can generate an interrupt or an interrupt signal, so that the ADSP can be woken up to respond to and process the interrupt.
一些实施例中，当AP处于唤醒状态的时候，ADSP可以通过接口文件的形式使能计步器中断，使得计步器中断信号会被ADSP处理，那么ADSP就会清楚地知道此时计步器上报的步伐数，同时将该步伐数上报给AP，可用于供计步器相关的应用使用。In some embodiments, when the AP is in the wake-up state, the ADSP can enable the pedometer interrupt in the form of an interface file, so that the pedometer interrupt signal will be processed by the ADSP, and then the ADSP will clearly know that the pedometer at this time The reported number of steps, and report the number of steps to the AP at the same time, which can be used for applications related to the pedometer.
需要说明的是，如果系统唤醒的时候，用户不走路了，而且计步器也不主动上报步伐的话，刚才用户在系统睡眠的时候走过的步伐就会丢失掉，造成计步的错误。因此，优选的，当系统被唤醒的时候，或者说，当所述AP处于唤醒状态时，不仅使能计步器中断，同时，要控制计步器主动将当前的计步器步伐数向ADSP上报，然后ADSP上报给AP。It should be noted that if the user does not walk when the system wakes up, and the pedometer does not actively report the steps, the steps that the user walked when the system was sleeping just now will be lost, resulting in an error in step counting. Therefore, preferably, when the system is woken up, or in other words, when the AP is in the wake-up state, not only enable the pedometer interrupt, but also control the pedometer to actively count the current pedometer steps to the ADSP Report, and then the ADSP reports to the AP.
这样，在ADSP架构下，通过动态调整计步器的中断，既可以实现准确计步，又可以降低ADSP的功耗，达到省电的目的。In this way, under the ADSP architecture, by dynamically adjusting the interruption of the pedometer, it can not only realize accurate step counting, but also reduce the power consumption of ADSP to achieve the purpose of saving electricity.
可以理解，本发明实施例上述方案例如可以在手机等终端具体实施。It can be understood that the above solutions of the embodiments of the present invention can be specifically implemented in terminals such as mobile phones, for example.
由上可见，在本发明的一些可行的实施方式中，可以动态调整传感器中断，其中，当AP处于休眠状态时，关闭传感器中断，使得ADSP不用响应传感器中断，不再处于被间断唤醒的状态，从而可以降低ADSP的功耗，达到使终端省电的目的，并且不影响传感器正常工作。As can be seen from the above, in some feasible embodiments of the present invention, the sensor interrupt can be dynamically adjusted, wherein, when the AP is in a dormant state, the sensor interrupt is turned off, so that the ADSP does not need to respond to the sensor interrupt, and is no longer in the state of being woken up intermittently. Therefore, the power consumption of the ADSP can be reduced to achieve the purpose of saving power of the terminal without affecting the normal operation of the sensor.
