Description

快速充电命令处理方法、装置及电子设备
本公开要求在2016年4月27日提交中国专利局、申请号为201610274206.2、的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及通用串行总线快速充电(Universal Serial Bus Power Delivery，USB-PD)技术领域，例如，涉及一种快速充电命令处理方法装置及电子设备。
背景技术
USB-PD是一种新兴的快速充电技术，主要通过Type-C接口实现该种快速充电设计，为了便于了解USB-PD充电技术，以下将先说明一下Type-C接口的基本结构。
Type-C接口的最大特点是支持从正反两面均可插入的“正反插”功能，其A面和B面分别具有12个针脚，每个针脚的布置如表1所示：
表1：
Figure PCTCN2016102966-appb-000001
其中，TX1+、TX1-，RX1+、RX1-，TX2+、TX2-，RX2+、RX2-为四对差分信号针脚，GND为接地针脚，D+、D-为用于兼容USB2.0的USB差分信号针脚，VBUS为电源针脚，CC1、CC2为用于探测正反插、区分主从、配置VBUS电压等的针脚，SBU1、SBU2为总线针脚。
由于Type-C接口具有四个电源针脚和四个接地针脚，因此，Type-C接口理论上能够支持100W的电源输出，这也是Type-C接口能够实现USB-PD快速充电的原因。
在此基础上，USB-PD快速充电是指通过USB的5V电压(VBUS)直流电平上耦合频移键控(Frequency-shift keying，FSK)信号来请求充电器调整输出电 压和电流的过程，该过程包括如下步骤1-5。
在步骤1中，手机识别插入的充电器是否为支持快速充电的PD充电器，如插入的充电器是支持快速充电的PD充电器，则进行切换，即将Type-C的差分信号针脚改为用于传输PD信号(包括PD命令和数据等)，将Type-C的SBU1、SUB2总线针脚改为用于传输辅助(Auxiliary，AUX)信号。
在步骤2中，启动USB-PD设备策略管理器，策略管理器监控VBUS的直流电平上耦合的FSK信号，并从中解码得到能力资源(Capabilities Source)消息，再根据USB-PD规范解析该消息得出PD充电器支持的所有电压和电流对列表。
在步骤3中，手机根据用户的配置从Capabilities Source消息中选择一个电压和电流对，并将电压和电流对加载至充电请求(Request)消息的载荷(payload)部分，然后，策略管理器将FSK信号耦合到VBUS直流电平上。
在步骤4中，充电器解码FSK信号并发出接收(Accept)消息给手机，同时调整充电器的输出电压和电流。
在步骤5中，手机接收到Accept消息后，调整充电IC的充电电压和电流。
在此，手机在充电过程中可以动态发送Request消息来请求充电器改变输出电压和电流，从而实现快速充电的过程。
由此可见，在进行快速充电的过程中，电子设备与PD充电器会进行交互而产生大量的快速充电命令(简称为PD命令)，这些命令与其他命令一样均将进入缓冲队列中排队等待处理，该种处理方式将影响对PD命令的处理速度，进而出现响应迟缓的问题。
发明内容

第六方面，本公开实施例还提供了一种计算机程序产品，所述计算机程序产品包括存储在非暂态计算机可读存储介质上的计算机程序，所述计算机程序包括程序指令，当所述程序指令被计算机执行时，使所述计算机执行上述的方法。

图1是本公开的PD命令处理方法的一种实施方式的流程图。
在步骤110中，电子设备一端在检测到与充电器建立连接后，识别插入通用串行总线(Universal Serial Bus，USB)接口的充电器是否为支持快速充电的快速充电(Power Delivery，PD)充电器，如插入USB接口的充电器是支持快速充电的PD充电器，则按照本公开方法处理对应PD充电器的PD命令，即执行以下步骤120至步骤160，如插入USB接口的充电器不是支持快速充电的PD充电器，则按照常规方式处理充电命令。
在步骤120中，创建用于处理快速充电命令的专用线程。
该步骤可以是占用现有的一个线程作为用于处理快速充电命令的专用线程；也可以是创建一个新的线程作为用于处理快速充电命令的专用线程，以尽可能减少对其他命令的处理速度的影响。
在步骤130中，创建专用线程后，进行等待接收处理通知的状态。
在此，电子设备一端在产生或者接收到PD命令时，会将PD命令写入内核链表，即内核中的列表list，此时，系统会根据该写入操作而触发处理通知，以通知专用线程已有PD命令排队等待处理，以使专用线程在接收到该处理通知后即开始从链表中接续读取PD命令进行处理的操作，此处的接续即为在接收到一次处理通知后，便一个接一个地完成对链表中的PD命令的处理，直至认为链表中的快速处理命令为空为止，而无需在完成对一条PD命令的处理后等待下一次处理通知，对应以下步骤140至步骤160。
在步骤140中，根据该处理通知，从链表中将一条快速充电命令读取至专用线程进行处理，之后执行步骤150。
该条快速充电命令在被读取至专用线程进行处理后，便从链表中删除或者 进行已处理标记。
在步骤150中，判断是否完成对当前快速充电命令的处理，如完成对当前快速充电命令的处理，则执行步骤160，如未完成对当前快速充电命令的处理，则继续执行步骤150，进行是否完成对当前快速充电命令的处理的判断。
在步骤160中，判断链表中的快速充电命令是否为空，如快速充电命令为空，则回到步骤130，进入等待接收处理通知的状态，如快速充电命令不为空，则回到步骤140，接续读取链表中的快速处理命令至专用线程进行处理。
在此，在根据一次处理通知进行从链表中接续读取PD命令进行处理，直至认为链表中的快速处理命令为空为止的过程中，可以采用遍历所述链表的方式确定链表中的快速处理命令是否为空，也可以采用每进行一次读取即从链表的开始位置进行搜索的方式。本公开在一个实施例中采用根据一次处理通知，遍历链表进行快速处理命令的搜索的方式，以提高搜索效率。
由于本公开方法会根据一次处理通知进行从链表中接续读取PD命令进行处理，直至认为链表中的快速处理命令为空为止的处理，因此，为了不影响对当前PD命令的处理，提高处理效率，在本公开的一个实施例中，在专用线程为忙时，即正在处理PD命令时，忽略接收到的处理通知，这说明，只有在专用线程空闲而处于等待接收处理通知的状态下，才会根据处理通知开始一轮搜索处理，而在专用线程为忙时，将不会根据此时接收到的处理通知开始下一轮的搜索处理。
由此可见，本公开方法是在识别到建立连接的充电器为PD充电器后，为PD命令创建仅用于处理PD命令的专用线程，并会根据每次接收到的处理通知接续进行链表中PD命令的处理，直至链表中的PD命令为空为止，这将明显提高对PD命令的处理速度，进而减少对PD命令的响应时间。
