- the second detection device 103 may also be a contact switch or a non-contact sensor.
- the first detection device 102 is a Hall sensor. When the rescuer opens or closes the lid of the AED with the magnet, the Hall sensor senses the change in the magnetic field and generates an on-off signal. The AED automatically turns on to enter the clinical work startup mode or enters a low level.
- the second detection device 103 is an in-position switch, when the rescuer opens or closes the AED cover, the in-position switch is triggered by the cover displacement, so that the in-position switch is in the on or off state to generate the switch Signal, the AED automatically turns on to enter the power-on mode of clinical work or enters the power-off mode of low-power work. Then, while the user opens or closes the AED cover, the second detection device 103 detects that the in-position switch is turned on or off.

Description
本申请涉及电子技术领域，尤其涉及一种开关机控制方法和除颤仪。
除颤仪是一个不经常使用的高风险急救设备，主要用于对心脏室颤，房颤等危险病症进行除颤治疗。自动除颤仪(Automated External Defibrillator，AED)是一种预期应用在院外公共场合(机场，车站等人流密集场所)的除颤仪。与院内常规除颤仪不一样，AED一般配置一次性电池，并运行固定周期的自动自检以达到少维护或免维护目标。一般公共场合AED配置一次性电池后待机寿命可到3-5年。目前从业界来看，有关AED的失效约20％为电池相关故障，其中电量耗尽的失效模式为绝大多数，该种失效会直接导致抢救时电池电量不足而无法进行抢救的情况，进而导致患者死亡。如何解决AED在待机过程中由于误开机导致的电池电量耗尽问题是业界难题。另一方面，AED一般由非专业医护人员使用，如何解决使用抢救过程中的误关机问题也具有较强的临床意义

为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述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1A为本申请实施例提供的一种除颤仪的结构示意图；
图1B为本申请实施例提供的一种瞬时干扰的频谱示意图；
图2为本申请实施例提供的一种开机控制方法；
图3为本申请实施例提供的一种关机控制方法。
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
以下对本申请实施例做详细描述。
请参阅图1A，图1A为本申请实施例提供的一种除颤仪的结构示意图，如图1A所示，本申请实施例提供一种除颤仪100，包括处理器101，以及独立检测除颤仪开、关机行为的第一检测设备102和第二检测设备103，即第一 检测设备102和第二检测设备103结合用于进行开关机控制。处理器101根据接收到的第一检测设备102和第二检测设备103的输出信号，确定是否进入开机模式；或第一检测设备102和第二检测设备103结合用于检测关机行为，处理器101根据接收到的第一检测设备102和第二检测设备103的输出信号，确定是否进入关机模式。
其中，处理器101可以是中央处理器(Central Process Unit，CPU)，也可以是微控制单元(Microcontroller Unit，MCU)，对于内部空间受限的除颤仪来说，后者的使用概率更高。
第一检测设备102可以是接触式开关或非接触式传感器，接触式开关包括在位开关、按键开关、弹簧开关等；非接触式传感器包括霍尔传感器、光电传感器、超声传感器、电容传感器等。同样的，第二检测设备103也可以是接触式开关或非接触式传感器。例如第一检测设备102为霍尔传感器，当施救者打开或关闭带有磁铁的AED盖子时，霍尔传感器感应到磁场变化产生开关机信号，AED自动开机进入临床工作的开机模式或进入低功耗待机的关机模式；第二检测设备103为在位开关，当施救者打开或关闭AED盖子时，通过盖子位移触发在位开关，使在位开关处于接通或断开状态产生开关机信号，AED自动开机进入临床工作的开机模式或进入低功耗工作的关机模式那么在用户打开或关闭AED盖子的同时，第二检测设备103检测到在位开关接通或断开的同时，第一检测设备102可同时感应到磁场的变化，进而同时触发产生开关机信号，这样同时触发的两个检测设备输出信号，可以减少因为一个检测设备输出信号无效或者错误而导致除颤仪误开、关机的概率，明显提升除颤仪开关机行为的稳定性和可靠性。
可选情况下，所述第一检测设备102为非接触式检测设备，所述第二检测设备103为接触式开关。
第一检测设备102和第二检测设备103为不同类型的检测设备，那么在一种检测设备的输出信号不稳定的情况下，采用不同类型的另一种检测设备，可以避免同样的环境因素或操作条件下造成的同类信号输出不稳定而导致的失 误问题，提升了除颤仪开关机行为的稳定性和可靠性。
可选的，处理器101根据第一检测设备102和第二检测设备103的输出信号，进入开机模式方面，具体包括：第一检测设备102检测到开机行为，则输出第一开机检测信号；第二检测设备103检测到开机行为，则输出第二开机检测信号；处理器101接收到第一开机检测信号或第二开机检测信号后，则进入开机模式。
具体地，用户通过第一检测设备102检测开机行为，当检测到开机行为后，输出第一开机检测信号，同样的，第二检测设备103能够输出第二开机检测信号，处理器101只需要接收到其中一个开机检测信号，即可进入开机模式，这样可以降低因检测设备的开机检测信号失误造成的除颤仪开机失败的问题，降低了临床风险。
可选的，所述处理器101接收到所述第一开机检测信号或第二开机检测信号后，先确认所述第一开机检测信号或第二开机检测信号有效，才进入开机模式。
具体地，在处理器101接收到开机检测信号后，可以只是一个干扰信号而并不是有效的开机检测信号，如果根据这个无效的开机检测信号进入开机模式，将会导致多余的除颤仪电量消耗，因此，先确定开机检测信号的有效性，能够避免误开机、延长除颤仪电池的寿命。确认开机检测信号有效性的方法包括：消除干扰信号、延长信号输入时间，确定开机检测信号的稳定性等方法。
可选的，在确认第一开机检测信号或第二开机检测信号是否有效时，处理器101具体执行下述步骤：判断接收到的第一开机检测信号的持续时长大于第一预设时长，则确定第一开机检测信号有效；判断接收到的第二开机检测信号的持续时长大于第一预设时长，则确定第二开机检测信号有效。
具体地，对于第一检测设备102和第二检测设备103，无论是接触式开关或者非接触式传感器，都可能在触发的过程中产生一些无效信号，例如接触不良或传感器接收到触发信号为临界值，可能导致检测设备输出信号，但是这种信号不能够有效触发处理器101进入开关机模式，因此需要通过判断信号的有效性，减少根据无效信号进行开关机操作对设备的损害。这种无效信号持续时 间短，可以根据信号持续时长是否达到第一预设时长来检测信号的有效性。在这个过程之前，先设置或获取第一预设时长。第一预设时长可以由用户设置可调整值，也可以由商家设定固定值，还可以根据处理器101接收到第一设备或第二设备的输出信号后，但没能成功进入开机模式这之间的时间差确定第一预设时长。
可选的，在检测去干扰处理后的第一开机检测信号或第二开机检测信号的持续时长大于第一预设时长之前，所述方法还包括：在多个时长缓存区域中的每一个时长缓存区域存储一个预设时长；随机获取一个时长缓存区域中的预设时长，作为第一预设时长。
在除颤仪中设备缓存模块，缓存模块中包括多个时长缓存区域，每个时长缓存区域中存储一个预设时长，当处理器101接收到第一开机检测信号或第二开机检测信号时，随机从一个时长缓存区域中获取一个预设时长作为第一预设时长，然后用于确定开机检测信号的有效性。这样，可以增加第一预设时长的随机性，避免第一预设时长设定失效的情况。
可选的，在多个时长缓存区域中的每一个时长缓存区域存储一个预设时长，包括：
在第一时长缓存区域中存储初始预设时长，初始预设时长为第一检测设备102或第二检测设备103中耗时最长的历史开机时长确定；
在第二时长缓存区域中存储第一检测设备102预设时长，第一检测设备102预设时长为处理器101以第一预设时间间隔获取第一检测设备102的多个历史开机无效时长，并根据多个历史开机无效时长中的最大值确定第一检测设备102预设时长；
在第三时长缓存区域中存储第二检测设备103预设时长，第二检测设备103预设时长为处理器101以第二预设时间间隔获取第二检测设备103的多个历史开机无效时长，并根据多个历史开机无效时长的均值确定第二检测设备103预设时长。
具体地，第一检测设备102的开机时长表示第一检测设备102检测开机行为，输出第一开机检测信号，处理器101接收到第一开机检测信号并进入开机模式整个过程消耗的时长，设为t1；同样的，第二检测设备103的开机时长表 示第二检测和设备检测开机行为到处理器101进入开机模式整个过程消耗的时长，设为t2，那么初始预设时长T
0的获取公式为：
T
0＝max(t1，t2) (1)
其中max(t1，t2)表示取t1和t2中的最大值。
第一检测设备102的开机无效时长表示第一检测设备102检测开机行为，输出第一开机检测信号，处理器101接收到第一开机检测信号但最后没有成功进入开机模式的整个过程消耗的时长，处理器101以第一预设时间间隔s1获取第一检测设备102的多个历史开机无效时长，因为一个运行良好的检测设备不会频繁发生开机无效的情况，因此s1可以是一个较大的时间间隔，例如1天，3天，10天等。多个可以是N个，N为大于0的整数，记为t11，t12，...，t1N，然后根据多个历史无效时长中的最大值确定第一检测设备102预设时长，该过程可以用公式表达为：
T
1＝max(t11，t12，...，t1N) (2)
其中T
1表示第一检测设备102预设时长。
同样的，第二检测设备103的开机无效时长表示第二检测设备103检测开机行为，输出第二开机检测信号，处理器101接收到第二开机检测信号但最后没有成功进入开机模式的整个过程消耗的时长，处理器101以第二预设时间间隔s2获取第二检测设备103的多个历史开机无效时长，s2可以与s1相同，也可以与s1不同，多个可以是M个，M为大于0的整数，记为t21，t22，...，t2M，然后根据多个历史开机无效时长的均值确定所述第二检测设备103预设时长，该过程可以用公式表达为：
其中T
2为第二检测设备103预设时长。
在本申请实施例中，通过设置多个缓存区域用于存储多个预设时长，然后从多个预设时长中获取第一预设时长，可以增加第一预设时长的随机性，避免第一预设时长设定失效的情况。另外，通过设置初始预设时长，第一检测设备102预设时长和第二检测设备103预设时长，可以使得第一预设时长随着设备的使用过程自主学习并改变，进一步提升了第一预设时长的有效性和准确率。
可选的，处理器接收到第一开机检测信号或第二开机检测信号后，先对接收到的第一开机检测信号或第二开机检测信号进行去干扰处理；再根据去干扰处理后的第一开机检测信号或第二开机检测信息进行开机信号的有效性判断。
具体地，开机检测信号中可能存在由设备开关操作产生，与电源线路、输出线路或晶体震荡器相关的干扰，其中电源线路的影响最大。去干扰的方法包括安装滤波器或软件中加入抗干扰指令等。第一监测设备102和第二监测设备103输出的第一、二开机检测信号经滤波器滤波处理后才输出给处理器101。
开机检测信号中的干扰有可能是瞬时干扰，瞬时干扰是一种时间短、频谱宽、幅度大的电磁干扰，包括电快速脉冲群、浪涌或静电放电。电快速脉冲群是电路中的电感性负载断开时产生，浪涌由雷电感应或者大功率开关产生，静电放电由雷电现象、人体接触设备时的静电放电、装置放电产生。对第一开机检测信号和第二开机检测信号进行滤波时，可能包括这三种瞬时干扰。
当然，在某些情况下，例如干扰比较小的情况下，处理器101也可以不对接收到的第一开机检测信号或第二开机检测信号进行滤波，直接用对接收到的第一开机检测信号或第二开机检测信号进行有效性判断。
请参阅图1B，图1B为本申请实施例提供的一种瞬时干扰的频谱示意图，其中图1B中的(a)表示瞬时干扰的振幅图，振幅为瞬时干扰达到的电流或电压，如图1B中的(a)所示，瞬时干扰的振幅能够在很短的时间内达到最大值，最大值可以是几千伏，或者几千安，然后快速回落，很短时间可能是微秒级或纳秒级。图1B中的(b)表示瞬时干扰的谐波幅度图，谐波振幅(电流或电压)随着频率的增大而减小。在对第一开机检测信号或第二开机信号进行滤波时，可以滤除在第一时间间隔内电压或电流超过预设电压或电流的信号，第一时间间隔可以是一个极小值，例如1微妙或4纳秒，预设电压可以是4kV(千伏)或50A(安)等；还可以是对谐波进行滤除，谐波为基波频率的整数倍，根据谐波这一特性设置滤除条件，即滤除基波频率的整数倍的信号，即可有效滤除谐波。
可选的，除颤仪还包括输入设备和电极片；在进入开机模式后，处理器101还执行下述步骤：在第二预设时长内通过输入设备或电极片检测用户的有效使用行为；如果在第二预设时长内没有检测到用户的有效使用行为，则进入 关机模式。在本文中，除了常规的关机状态，关机模式还可包括除颤仪进入维持必要检测、自检或系统运行中一项或多项的低功耗工作模式，例如在低功耗模式下，控制状态指示灯或蜂鸣器来指示机器状态，定期进行唤醒自检等。
具体地，由于误操作等，在处理器101进入开机模式后，可能存在设备空置的情况，即设备没有被使用，在这种情况下，处理器101可以进入关机模式，以减少除颤仪电量消耗。因此，处理器101可以在第二预设时长内通过输入设备或电极片检测用户的有效使用行为以确定是否存在设备空置的情况，如果在所述第二预设时长内没有检测到用户的有效使用行为，则进入关机模式。输入设备包括实体按键、触摸屏、语音输入设备等。第二预设时长可以由用户根据实际使用情况设置可变时长，也可以由出厂商设置固定时长，可以是10分钟，15分钟等。另外，用户的有效使用行为包括：电极片与人体连接、修改除颤仪设置，以及控制除颤仪进行除颤、模拟中的一个或多个。
具体地，电极片用来与人体连接进行临床治疗，通过检测电极片是否与人体连接可确定是否有用户的有效使用行为。除颤仪的输入设备，包括键盘或触摸屏等，可以接收用户对除颤仪的操作或设置，以及控制除颤仪进行除颤或模拟，处理器101检测到这些行为中的一种或多种，可以确定检测到用户的有效使用行为。
可选的，第一检测设备102检测到关机行为，还输出第一关机检测信号；第二检测设备103检测到关机行为，还输出第二关机检测信号；处理器101接收到第一关机检测信号和/或第二关机检测信号后，进入关机模式。
具体地，第一检测设备102和第二检测设备103都可以检测关机行为，并输出关机检测信号。处理器101接收到第一关机检测信号和/或第二关机检测信号后，进入关机模式，包括两种情况：(1)处理器101接收到第一关机检测信号或第二关机检测信号后，进入关机模式；(2)处理器101接收到第一关机检测信号和第二关机检测信号后，进入关机模式。
对于情况(1)，处理器101只要接收到第一关机检测信号或第二关机检测信号中的一个，就可以进入关机模式，这样有助于快速关机。
对于情况(2)，处理器101需要同时接收到第一关机检测信号和第二关机检测信号后，进入关机模式，这里的“同时”表示发生的时间间隔小于第一预设 关机间隔，第一预设时间间隔可以是一个很小的值，例如1秒，30毫秒等。处理器101如果只检测到一个关机检测信号，可能是用户的误关机操作，误关机操作可能导致除颤仪使用过程中发生临床风险，因此，在同时检测到第一关机检测信号和第二关机检测信号后，进入关机模式，能够降低临床风险，提高进入关机模式的准确率。
可选的，处理器101在接收到第一关机检测信号和/或第二关机检测信号后，先确认第一关机检测信号和/或第二关机检测信号有效，才进入关机模式。
具体地，第一关机检测信号和第二关机检测信号可能是无效信号，例如因为环境影响造成的第一检测设备102或第二检测设备103的传感器失灵，或者因为接触不良或操作失误造成的第一检测设备102或第二检测设备103的接触式开关的无效操作。因此，确定关机检测信号有效的过程与上述处理器101根据接收到的关机检测信号进入关机模式的2中情况是相互对应的，如果处理器101接收到第一关机检测信号或第二关机检测信号，那么需要确定第一关机检测信号或第二关机检测信号的有效性，然后进入关机模式；如果处理器101接收到第一关机检测信号和/或第二关机检测信号，那么需要确定第一关机检测信号和/或第二关机检测信号的有效性，如果确定第一关机检测信号和/或第二关机检测信号的有效，然后才进入关机模式。确定关机检测信号有效的方法与确定开机检测信号有效的方法相同，包括消除干扰信号、延长信号输入时间，确定开机检测信号的稳定性等方法。
可选的，处理器101判断接收到的第一关机检测信号的持续时长大于第三预设时长，则确定第一关机检测信号有效；处理器101判断接收到的第二关机检测信号的持续时长大于第三预设时长，则确定第二关机检测信号有效。
具体地，根据上述实施例，第一检测设备102和第二检测设备103都有可能输出无效的关机信号，例如因为环境影响或者传感距离处理临界值造成的第一检测设备102或第二检测设备103的传感器失灵，或者因为接触不良、操作失误造成第一检测设备102或第二检测设备103的接触式开关输出无效关机信号。但由于这些信号的持续时间短，不足以使处理器101执行关机操作，因此，在确定第一关机检测信号和第二关机检测信号的有效性时，可以通过确定第一关机检测信号或第二关机检测信号的持续时长是否大于第三预设时长来判断。 第三预设时长可以由用户设置可调整值，也可以由商家设定固定值，还可以根据处理器101接收到第一设备或第二设备的输出信号后，但没能成功进入关机模式这之间的时间差确定。
可选的，处理器接收到第一关机检测信号或第二关机检测信号后，先对接收到的第一关机检测信号或第二关机检测信号进行去干扰处理；再判断去干扰处理后的第一关机检测信号或第二关机检测信息进行关机信号的有效性。
与上述开机过程相同，关机过程也会产生干扰，对第一关机检测信号或第二关机检测去干扰，使得得到的关机检测信号更准确，更好地用于判断关机信号的有效性。去干扰的过程与开机检测信号去干扰的过程相同。
可选的，处理器在进入关机模式前，还执行下述步骤：通过输入设备或电极片检测用户的有效使用行为；如果检测到用户的有效使用行为，则停止进入关机模式。
具体地，确定关机信号有效后，如果用户还在使用除颤仪，关闭除颤仪可能导致使用过程中断，造成临床事故，因此检测用户的有效使用行为，如果检测到用户的有效使用行为，则停止进入关机模式。
可见，在本申请实施例中，通过设置第一检测设备和第二检测设备，并根据第一检测设备和第二检测设备的输出信号，确定除颤仪进入开机模式或关机模式，这样通过两个检测设备提升了开关机功能的可靠性，减少了AED无法开机、误开机或误关机的概率，最终在降低临床风险的情况下，延长了除颤仪电池的寿命。
本申请实施例还提供一种开关机控制方法，应用于上述实施例中所述的除颤仪，所述方法包括：所述处理器根据所述第一检测设备和第二检测设备的输出信号，进入开机模式或关机模式。
