 有益效果
1. 由于将双电源转换开关的触头组对应于计算机的键盘的键以及将触头组状态对应于键状态，而键盘上的键数量少则61个，多则104个，因此，可对应的触头组数量介于61个至104个之间。而开关的一极需要2个按键对应于触头组，一台四极开关就需要8个按键对应，因此，一个键盘可同时采集检测7台至13台四极开关的触头同步性。因而，采用本发明公开的采集检测方法或者采集检测装置来采集检测双电源转换开关的触头同步性的效率显著提高。
2. 由于本发明公开的采集检测方法的检测精度基于计算机的设备频率，而目前主流的计算机的设备频率在1000000hz以上，因此，用本发明公开的采集检测方法或者采集检测装置检测双电源转换开关的触头同步性可获得微秒级的检测精度，检测精度显著提高。
3. 获取并存储第一键组处于闭合状态时的计算机的计数器的第一数值组，使得当触头保持在第一电源侧时，系统一直采集并存储当前的第一数值组，第一数值组包括了第一电源侧各极触头组的计数值。当触头组断开的瞬间，即第一键组断开的瞬间，系统不再采集并存储各极对应的计数值，因此，存储单元里存储的计数值是触头组断开瞬间时的第一数值组，此第一数值组准确反映了第一电源侧各极触头组断开瞬间的计数值。
4. 获取并存储第二键组处于闭合状态时的计算机的计数器的第二数值组，分别计算第一数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第一差值组以及分别计算第二数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第二差值组。将计算步骤直接设置于完成采集第二数值组时，使得当触头接触到第二电源侧的瞬间，即第二键组闭合的瞬间，系统即可采集并存储当前计数器的第二数值组，此第二数值组里的每个数值都准确反映了第二电源侧对应极的触头组闭合瞬间的计数值，并分别计算第一数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第一差值组以及分别计算第二数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第二差值组。此第一差值组和第二差值组准确反映了双电源转换开关各极的触头同步性。
5. 根据第二辅助参数组的值获取并存储第二键组处于闭合状态时的计数器的第二数值组。由于设置了第二辅助参数组，使得第二数值组的值的获取是基于第二辅助参数组的值，因此，只有在第二辅助参数组的值满足预设条件时，系统才获取并存储触头组闭合状态时的计数器的计数值，保证了参与计算的第二数值组值为各极触头组闭合瞬间或者断开瞬间的计数值。
6. 在获取并存储第二数值组之后，第二辅助参数组的值改变。这样的设置使得当触头组闭合第二电源的瞬间，系统采集到第二数值组后第二辅助参数组的值改变，由于第二数值组的值的获取是基于第二辅助参数组的值，因此，在第二辅助参数组的值变化后，系统不再获取并存储触头组闭合状态时的计数器的计数值，保证了系统获取并存储的第二数值组的值为各极触头组闭合瞬间的计数值。
7. 在第一辅助参数组的值、第二位置参数的值以及第一键组的状态满足预设条件时分别计算第一数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第一差值组以及分别计算第二数值组中各个数值与其中一个数值的差值进而获得由多个差值组成的第二差值组。使得本发明公开的检测方法或者检测装置不仅可以检测双电源转换开关从第一电源侧转换到第二电源侧过程中的触头同步性，还能在不改变双电源转换开关接线端子与检测装置的接线方法的情况下继续测定双电源转换开关从第二电源侧切换回第一电源侧过程中的触头同步性，因此，本发明公开的检测方法或者检测装置可以连续不间断地检测双电源转换开关多个切换周期中的各极的触头同步性，为进一步判断频繁操作对触头同步性的影响提供基础数据。

 本发明的实施方式
图12-14是双电源转换开关其中一极的触头动作示意图，A为用于联接第一电源的第一接线端，B为用于联接第二电源的第二接线端，L为用于联接负载的第三接线端。如图12所示，当前动触头位于第一电源侧，负载电路与第一电源的电气联接状态为接通状态，负载电路与第二电源的电气联接状态为分断状态，当前负载电路由第一电源供电。如图13所示，当前动触头位于第一电源侧和第二电源侧之间，负载电路与第一电源的电气联接状态为分断状态，负载电路与第二电源的电气联接状态为分断状态，当前负载电路无供电电源。如图14所示，当前动触头位于第二电源侧，负载电路与第一电源的电气联接状态为分断状态，负载电路与第二电源的电气联接状态为接通状态，当前负载电路由第二电源供电。在此，将电气接通或分断第一电源与负载电路的触头组定义为第一电源触头组，将电气接通或分断第二电源与负载电路的触头组定义为第二电源触头组。
如图15所示的触头组示意图，负载电路的切换过程为动触头从第一电源的静触头断开至动触头接触到第二电源，在这个切换过程中包括了一个分断动作和一个接通动作，因此，一台四极双电源转换开关的一次切换过程就包括4个分断动作和4个接通动作，具体为第一电源侧的A相、B相、C相及N相的分断动作和第二电源的A相、B相、C相及N相接通动作。如图15所示，四极双电源转换开关具有4个联动的用于接通与分断第一电源或第二电源的触头组，因此，在一次切换过程中包括了分断同步性和接通同步性。而一个分断同步性的检测需要同时采集4个电路的通断情况，分别为A相、B相、C相及N相的触头组由原先的闭合状态转换为断开状态，同样地，一个接通同步性的检测需要同时采集4个电路的通断情况，分别为A相、B相、C相及N相的触头组由原先的断开状态转换为闭合状态。所以，在负载电路从第一电源侧切换到第二电源侧的过程中需要同时采集8个电路的通断情况。双电源转换开关的一个转换周期为负载电路从第一电源侧切换到第二电源侧再从第二电源侧切换回第一电源侧。
图16是计算机键盘的电路板示意图，其包括用于联接计算机的USB接口或者PS2接口、用于获取闭合信号的信号输入端以及处理输入与输出信号的电子电路处理单元，其中信号输入端包括多个平行排列的触点，电气接通其中的两个触点，计算机会获取到键盘上的某个键对应的字符。目前，键盘上的键数量少则61个，多则104个，因此，可对应的字符数量介于61个至104个之间。
图17是根据本申请一示例性实施例提供的采集装置的示意图，其包括计算机键盘的电路板以及与电路板电气联接的采样端，采样端包括多个采样线，采样线用于电气联接双电源转换开关的接线端。如图17所示，该装置用于联接计算机与双电源转换开关，以一台四极双电源转换开关为例，采样装置的采样端包括9个采样线，标号分别为1-7、14、19。用19号采样线去分别接通1-7及14号采样线计算机会分别获得不同的字符，如表1所示。其中，1、3、5、7号采样线分别用于电气联接第一电源的A相、B相、C相及N相，2、4、6、14号采样线分别用于电气联接第二电源的A相、B相、C相及N相，19号采样线用于电气联接负载，19号采样线为共用线，所以可以不区分ABCN相，将负载端的各相电气联接一起后再与19号采样线电气联接。如表1所示的线号、字符、相序及电源对照关系。
图1是根据本申请一示例性实施例提供的一种双电源转换开关触头同步性检测方法的流程图，如图1所示，该方法运用于双电源转换开关触头同步性的测定，以一台双电源转换开关为例，该测定方法包括以下步骤：
步骤101，对应步骤，将双电源转换开关的触头组对应于计算机的键盘的键，将触头组状态对应于键状态，由多个键组成的第一键组对应于由第一电源侧的多个触头组组成的第一电源触头组，由多个其它键组成的第二键组对应于由第二电源侧的多个触头组组成第二电源触头组。
作为一示例性实施例，第一键组包括第一键q、第二键e、第三键u及第四键o，第二键组包括第五键w、第六键r、第七键i及第八键p。第一电源触头组包括第一触头组、第二触头组、第三触头组及第四触头组，第二电源触头组包括第五触头组、第六触头组、第七触头组及第八触头组。第一电源侧的A相、B相、C相及N相分别对应于第一触头组、第二触头组、第三触头组及第四触头组，第一键q、第二键e、第三键u及第四键o分别对应于第一触头组、第二触头组、第三触头组及第四触头组。第二电源侧的A相、B相、C相及N相分别对应于第五触头组、第六触头组、第七触头组及第八触头组，计算机键盘的第五键w、第六键r、第七键i及第八键p分别对应于第五触头组、第六触头组、第七触头组及第八触头组。因此，第一触头组和第五触头组对应于同一极，第二触头组和第六触头组对应于同一极，第三触头组和第七触头组对应于同一极，第四触头组和第八触头组对应于同一极。触头组的断开状态对应的计算机的键盘的键状态为复位状态，触头组的闭合状态对应的计算机的键盘的键状态为闭合状态。因此，以开关的其中一极为例，当第一触头组闭合时，计算机获取到的字符是q；当第一触头组断开时，计算机不再获取到字符q。当第五触头组闭合，计算机获取到的字符是w；当第五触头组断开时，计算机不再获取到字符w。
步骤102，频率获取步骤，获取计算机的设备频率值。
以编程语言C++为例，通过指令QueryPerformanceFrequency ( ) 可以获得当前计算机的设备频率值。
步骤103，计数值获取步骤，获取并存储第一键组处于闭合状态时的计算机的计数器的第一数值组，第一数值组中的各值对应于第一键组中相应的键处于闭合状态时的计数器的计数值；获取并存储第二键组处于闭合状态时的计算机的计数器的第二数值组，第二数值组中的各值对应于第二键组中相应的键处于闭合状态时的计数器的计数值。
通过获取计数器的计数值并存储当前计数值，可以标定当前事件发生时对应的计数值。具体而言，
获取第一键q处于闭合状态时的计算机的计数器的第一数值，并存储第一数值；
获取第二键e处于闭合状态时的计算机的计数器的第二数值，并存储第二数值；
获取第三键u处于闭合状态时的计算机的计数器的第一数值，并存储第三数值；
获取第四键o处于闭合状态时的计算机的计数器的第二数值，并存储第四数值；
将由第一数值、第二数值、第三数值及第四数值组成的数值组表示为第一数值组。
获取第五键w处于闭合状态时的计算机的计数器的第五数值，并存储第五数值；
获取第六键r处于闭合状态时的计算机的计数器的第六数值，并存储第六数值；
获取第七键i处于闭合状态时的计算机的计数器的第七数值，并存储第七数值；
获取第八键p处于闭合状态时的计算机的计数器的第八数值，并存储第八数值；
将由第五数值、第六数值、第七数值及第八数值组成的数值组表示为第二数值组。
当双电源转换开关将负载电路从从第一电源侧切换到第二电源侧的过程中，第一电源触头组由原先的闭合状态转变为断开状态，第二电源触头组由原先的断开状态转变为闭合状态。就对应于同一极的两个键而言，第一键q由闭合状态转变为断开状态后第五键w由断开状态转变为闭合状态，第二键e由闭合状态转变为断开状态后第六键r由断开状态转变为闭合状态，第三键u由闭合状态转变为断开状态后第七键i由断开状态转变为闭合状态，第四键o由闭合状态转变为断开状态后第八键p由断开状态转变为闭合状态。
以编程语言C++为例，通过指令GetAsyncKeyState( )可以判断当前按键是否被按下，即判断第一键q、第二键e、第三键u、第四键o、第五键w、第六键r、第七键i、或者第八键p是否闭合。通过指令QueryPerformanceCounter( )可以获得当前计数器的计数值并存储计数值。因此，可以通过指令if (GetAsyncKeyState( )<0) { QueryPerformanceCounter( )}来获取第一键组中各个键处于闭合状态时的计数器的计数值以及获取第二键组中各个键处于闭合状态时的计数器的计数值，即可以获得由第一电源触头组中各个触头组处于闭合状态时的计数器的计数值组成的第一数值组以及获得由第二电源触头组中各个触头组处于闭合状态时的计数器的计数值组成的第二数值组。
由于程序是按指令来执行的，每个参数所存储的数值都是用当前获取到的数值覆盖现有的值，因此，第一触头组处于闭合状态时，计算机用当前获取到的计数值覆盖之前存储的计数值，所以第一数值是实时更新的。当第一触头组由闭合状态转变为断开状态，计算机不再获取并存储计数值，因此，所存储的第一数值为第一触头组由闭合转变为断开的瞬间时计算机获得的计数值，所以第一数值真实有效。同样的道理，第二数值、第三数值及第四数值也是真实有效的，即第一数值组是真实有效的。当第五触头组处于闭合状态时，获取并存储计算机的计数器的第五数值。因此，当第五触头组闭合的瞬间，计算机就获取到计数器当前的计数值并存储在第五数值里。由于第五触头组闭合后就保持在闭合状态，为了避免第五数值被更新造成第五数值存储的不是第五触头组闭合瞬间的计数值，将计算步骤直接设置于获取并存储第五数值之后。这样的设置确保了获取并存储第五数值的指令只执行一次，而且是在第五触头组闭合的瞬间执行的，所以第五数值真实有效。同样的道理，第六数值、第七数值及第八数值也是真实有效的，即第二数值组是真实有效的。
步骤104，计算步骤，分别计算第一数值组中各个数值与其中一个数值的差值，将差值除以设备频率值，进而获得由多个时间差值组成的第一差值组；分别计算第二数值组中各个数值与其中一个数值的差值，将差值除以设备频率值，进而获得由多个时间差值组成的第二差值组。存储第一差值组和第二差值组，第一差值组准确反映了双电源转换开关各极触头组分断第一电源的同步性，第二差值组准确反映了双电源转换开关各极触头组接通第二电源的同步性。
作为一示例性实施例，将第一数值作为第一数值组中的基准值，计算第一数值与第一数值的差值，计算第二数值与第一数值的差值，计算第三数值与第一数值的差值，计算第四数值与第一数值的差值，将这些差值分别除以设备频率值可以获得一个以时间为单位的时间值，所得的时间值标定的是对应相的触头组比A相的触头组提前或者滞后分断第一电源的时间值，所以第一差值组内的各个时间值可以准确反映开关各极触头组的分断同步性。同样的道理，将第五数值作为第二数值组中的基准值，计算第五数值组与第五数值组的差值，计算第六数值组与第五数值组的差值，计算第七数值组与第五数值组的差值，计算第八值组与第五数值组的差值，将这些差值分别除以设备频率值可以获得一个以时间为单位的时间值，所得的时间值标定的是对应相的触头组比A相的触头组提前或者滞后接通第二电源的时间值，所以第二差值组内的各个时间值可以准确反映开关各极触头组的接通同步性。
由于本实施例公开的检测方法的检测精度基于计算机的设备频率，而目前主流的计算机的设备频率在1000000hz以上，因此，用本发明公开的采集检测方法测定双电源转换开关的触头同步性可获得微秒级的检测精度，检测精度显著提高。由于将双电源转换开关的触头组对应于计算机的键盘的键以及将触头组状态对应于键状态，而键盘上的键数量少则61个，多则104个，因此，可对应的触头组数量介于61个至104个之间。而开关的一极需要2个按键对应于触头组，一台四极开关就需要8个按键对应，因此，一个键盘可同时采集检测7台至13台四极开关的触头同步性。因而，采用本发明公开的采集检测方法测定双电源转换开关的触头同步性的效率显著提高。
图3是根据本申请一示例性实施例提供的一种获取并存储第一数值组的流程图，该方法用于根据第一辅助参数组的值获取并存储第一键组处于闭合状态时的计算机的计数器的第一数值组。如图3所示，该方法包括以下步骤：
步骤201，提供第一辅助参数组。
作为一示例性实施例，双电源开关将负载电路从第一电源侧切换到第二电源侧。第一辅助参数组包括第一辅助参数、第二辅助参数、第三辅助参数及第四辅助参数。在采集测定程序运行前期将第一辅助参数组中所有辅助参数的值均初始化为0，第一辅助参数组用于辅助执行第一数值组获取指令，第一数值组获取的预设条件为第一辅助参数组的值为0。具体地，当第一辅助参数的值为0时执行获取第一数值指令，当第二辅助参数的值为0时执行获取第二数值指令，当第三辅助参数的值为0时执行获取第三数值指令，当第四辅助参数的值为0时执行获取第四数值指令。
步骤202，检测到第一键组处于闭合状态。
步骤203，判断第一辅助参数组的值是否满足预设条件。
步骤204，若第一辅助参数组的值满足预设条件，计算机获取并存储第一数值组。若第一辅助参数组的值不满足预设条件，计算机放弃获取第一数值组。
当双电源开关的第一电源触头组闭合后，即第一键q、第二键e、第三键u及第四键o均处于闭合状态，判断第一辅助参数组是否满足预设条件，由于第一辅助参数组中各辅助参数的值均已被初始化为0，因此，第一辅助参数组满足条件，计算机获取计数器此时的计数值，并将获取到的计数值存储于第一数值组。具体地，根据第一辅助参数的值获取并存储对应于第一键q的第一触头组在闭合时的第一数值，根据第二辅助参数的值获取并存储对应于第二键e的第二触头组在闭合时的第二数值，根据第三辅助参数的值获取并存储对应于第三键u的第三触头组在闭合时的第三数值，根据第四辅助参数的值获取并存储对应于第四键o的第四触头组在闭合时的第四数值。
由于双电源开关在切换前，第一电源触头组和第二电源触头组保持当前位置，因此，第一电源触头组保持在闭合状态，所以计算机持续获取计数器当前的计数值并存储于第一数值组，因而，第一电源触头组闭合后在第一辅助参数组中个的各个辅助参数的值为0的条件下，第一数值组中的各个数值持续处于实时更新状态。
当第一电源触头组保持在闭合状态，而第一辅助参数组中的各个辅助参数的值为非0的其它数，即第一辅助参数组中的各个辅助参数的值不满足预设条件，则计算机放弃获取计数器当前的计数值。可以通过指令
if (GetAsyncKeyState(‘q’)<0 && (na==0)) { QueryPerformanceCounter( )}
if (GetAsyncKeyState(‘e’)<0 && (nb==0)) { QueryPerformanceCounter( )}
if (GetAsyncKeyState(‘u’)<0 && (nc==0)) { QueryPerformanceCounter( )}
if (GetAsyncKeyState(‘o’)<0 && (nn==0)) { QueryPerformanceCounter( )}
来获取第一键组处于闭合状态时的计数器的计数值，即可以获得第一电源触头组处于闭合状态时的计数器的计数值，其中na、nb、nc、nn分别为第一辅助参数、第二辅助参数、第三辅助参数及第四辅助参数。
图4是根据本申请一示例性实施例提供的一种获取并存储第二数值组的流程图，该方法用于根据第二辅助参数组的值获取并存储第二键组处于闭合状态时的计算机的计数器的第二数值组。如图4所示，该方法包括以下步骤：
步骤301，提供第二辅助参数组。
作为一示例性实施例，双电源开关将负载电路从第一电源侧切换到第二电源侧。第二辅助参数组包括第五辅助参数、第六辅助参数、第七辅助参数及第八辅助参数。在采集测定程序运行前期将第二辅助参数组中所有辅助参数的值均初始化为0，第二辅助参数组用于辅助执行第二数值组获取指令，第二数值组获取的预设条件为第二辅助参数组的值为0。具体地，当第五辅助参数的值为0时执行获取第五数值获取指令，当第六辅助参数的值为0时执行获取第六数值获取指令，当第七辅助参数的值为0时执行获取第七数值获取指令，当第八辅助参数的值为0时执行获取第八数值获取指令。
步骤302，检测到第二键组处于闭合状态。
步骤303，判断第二辅助参数组的值是否满足预设条件。
步骤304，若第二辅助参数组的值满足预设条件，计算机获取并存储第二数值组。若第二辅助参数组的值不满足预设条件，计算机放弃获取第二数值组。
当双电源开关的第二电源触头组闭合后，即第五键w、第六键r、第七键i及第八键p均处于闭合状态，判断第二辅助参数组是否满足预设条件，由于第二辅助参数组中的各辅助参数的值均已被初始化为0，因此，第二辅助参数组满足条件，计算机获取计数器此时的计数值，并将获取到的计数值存储于第二数值组，再将第二辅助参数组的值由0改变为1。具体地，根据第五辅助参数的值获取并存储对应于第五键w的第五触头组在闭合时的第五数值，再将第五辅助参数的值由0改变为1；根据第六辅助参数的值获取并存储对应于第五键r的第六触头组在闭合时的第六数值，再将第六辅助参数的值由0改变为1；根据第七辅助参数的值获取并存储对应于第六键i的第七触头组在闭合时的第七数值，再将第七辅助参数的值由0改变为1；根据第八辅助参数的值获取并存储对应于第七键p的第八触头组在闭合时的第八数值，再将第八辅助参数的值由0改变为1。由于第二辅助参数组的值更新为1不再满足第二数值组获取的预设条件，所以计算机不再获取并存储第二数值组，因此，当前的第二数值组为第二电源触头组闭合瞬间计算机所获取的计数器的计数值。
虽然第二键组继续处于闭合状态，但由于第二辅助参数组的值不满足获取并存储第二数值组的预设条件，所以计算机放弃获取第二数值组。可以通过指令
if (GetAsyncKeyState(‘w’)<0 && (ra==0)) { QueryPerformanceCounter( ); ra++;}
if (GetAsyncKeyState(‘r’)<0 && (rb==0)) { QueryPerformanceCounter( ) ; rb++;}
if (GetAsyncKeyState(‘i’)<0 && (rc==0)) { QueryPerformanceCounter( ) ; rc++;}
if (GetAsyncKeyState(‘p’)<0 && (rn==0)) { QueryPerformanceCounter( ) ; rn++;}
来获取第二键组在闭合瞬间的计数器的计数值，即可以获得第二电源触头组在闭合状态瞬间的计数器的计数值，其中na、nb、nc、nn分别为第五辅助参数、第六辅助参数、第七辅助参数及第八辅助参数。
图5是根据本申请一示例性实施例提供的一种改变第一位置参数的值的流程图，该方法用于在计算机获取第一数值组之后改变第一位置参数的值。如图5所示，该方法包括以下步骤：
步骤401，提供第一位置参数。
作为一示例性实施例，在采集测定程序运行前期将第一位置参数的值初始化为0。第一位置参数用于辅助指示当前负载电路所接入的电源信息。
步骤402，获取第一数值组。
步骤403，改变第一位置参数的值。
获取到第一数值组说明第一电源触头组处于闭合状态，即表示当前负载电路由第一电源供电，可以通过指令cout 将当前的工作电源显示于屏幕。而显示指令的执行条件是第一键组处于闭合状态且第一位置参数的值为0，由于第一位置参数已被初始化为0，因此，在第一键组中的所有键均闭合后，即计算机获取到第一数值组中的所有数值后，计算机屏幕上即可显示出当前的负载电路所接入的电源为第一电源，然后第一位置参数的值由0改变为1。由于此时的第一位置参数的值不是0，因此显示指令不再执行，确保了电源指示信息在一次切换中只显示一条，避免了电源指示信息以刷屏的方式出现。
图6是根据本申请一示例性实施例提供的一种改变第二辅助参数组的值的流程图，该方法用于在计算机获取并存储第二数值组之后改变第二辅助参数组的值。如图6所示，该方法包括以下步骤：
步骤501，提供第二辅助参数组。
第二辅助参数组用于在双电源开关从第一电源侧切换到第二电源侧的过程中判断是否获取并存储第二数值组的依据。
步骤502，获取并存储第二数值组。
在双电源开关从第一电源侧切换到第二电源侧后，第二电源触头组由断开状态转变为闭合状态，即第二键组处于闭合状态，计算机获取并存储第一数值组。
步骤503，改变第二辅助参数组的值。
在获取并存储第二数值组之后改变第二辅助参数组的值。由于双电源开关是将负载电路从第一电源侧切换到第二电源侧，因此，获取并存储第二数值组的时刻为第二键组闭合的瞬间，所以在获取并存储第二数值组后将第二辅助参数组的值改变以使获取第二数值组的预设条件不满足，从而避免当前已存储的第二数值组被更新，进而保证第二数值组的真实有效性。
图7是根据本申请一示例性实施例提供的一种改变第二位置参数的值的流程图，该方法用于在获取并存储第二数值组之后改变第二位置参数的值。如图7所示，该方法包括以下步骤：
步骤601，提供第二位置参数。
作为一示例性实施例，在采集测定程序运行前期将第二位置参数的值初始化为0。第二位置参数用于辅助指示当前负载电路所接入的电源信息。
步骤602，获取第二数值组。
步骤603，改变第二位置参数的值。
获取到第二数值组说明第二电源触头组处于闭合状态，即表示当前负载电路由第二电源供电，可以通过指令cout 将当前的工作电源显示于屏幕。由于第二位置参数的初始值为0，在双电源转换开关从第一电源转换到第二电源后，即在计算机获取到第二数值组后，第二位置参数的值由0改变为1。所以，显示指令的执行条件是第二键组处于闭合状态且第二位置参数的值为1，因此，在第二键组闭合后，即计算机获取到第二数值组后，计算机屏幕上即可显示出当前的负载电路所接入的电源为第二电源，然后第二位置参数的值由1改变为2。由于此时的第二位置参数的值不是1，因此显示指令不再执行，确保了电源指示信息在一次切换中只显示一条，避免了电源指示信息以刷屏的方式出现。
图8是根据本申请一示例性实施例提供的一种改变第一辅助参数组的值的流程图，该方法用于在获取并存储第一数值组之后改变第一辅助参数组的值，作为一示例性实施例，双电源开关将负载电路从第二电源侧切换回第一电源侧。如图8所示，该方法包括以下步骤：
步骤701，提供第一辅助参数组。
第一辅助参数组用于在双电源开关从第一电源侧切换到第二电源侧后再从第二电源侧切换回第一电源侧的过程中判断是否获取并存储第一数值组的依据。
步骤702，获取并存储第一数值组。
在双电源开关从第二电源侧切换回第一电源侧后，第一电源触头组由断开状态转变为闭合状态，即第一键组处于闭合状态，计算机获取并存储第一数值组。
步骤703，改变第一辅助参数组的值。
在获取并存储第一数值组之后改变第一辅助参数组的值。由于双电源开关是将负载电路从第二电源侧切换回第一电源侧，因此，获取并存储第一数值组的时刻为第一键组闭合的瞬间，所以在获取并存储第一数值组后改变第一参数组的值以使获取第一数值组的预设条件不满足，从而避免当前已存储的第一数值组被更新，进而保证第一数值组的真实有效性。
图10是根据本申请一示例性实施例提供的一种双电源转换开关触头同步性检测方法的流程图，如图10所示，该方法运用于双电源转换开关触头同步性的检测，以一台双电源转换开关为例，检测双电源开关在前半个转换周期即从第一电源侧切换到第二电源侧过程中的各极触头分断第一电源的同步性，该检测方法包括以下步骤：

步骤904，改变第一辅助参数组的值。
在存储第一数值组之后改变第一辅助参数组的值以使第一辅助参数组的值不满足获取第一数值组的预设条件，从而使存储的第一数值组为第一电源触头组闭合的瞬间计数器的计数值。
步骤905，判断第一辅助参数组的值、第二位置参数的值以及第一键组的状态是否满足条件。
预设条件为：第一辅助参数组的值为2，第二位置参数的值为2，第一键组的状态为闭合状态。具体地，第一键组的状态为闭合状态表明第一电源触头组当前处于闭合状态；第二位置参数为2表明屏幕上已显示负载电路当前接入第一电源；第一辅助参数组的值为2表明计算机已获取并存储第一键组闭合瞬间计数器的计数值。
步骤906，分别计算第一数值组中各个数值与其中一个数值的差值，将差值除以设备频率值，进而获得由多个时间差值组成的第一差值组。

步骤908，储存所得到的第一差值组和第二差值组。
步骤909，输出所得到的第一差值组和第二差值组。
在第一辅助参数组的值、第二位置参数的值以及第一键组的状态满足预设条件下执行计算步骤。
作为一示例性实施例，将第一数值作为第一数值组中的基准值，计算第一数值与第一数值的差值，计算第二数值与第一数值的差值，计算第三数值与第一数值的差值，计算第四数值与第一数值的差值，将这些差值分别除以设备频率值可以获得一个以时间为单位的时间值，所得的时间值标定的是对应相的触头组比A相的触头组提前或者滞后接通第一电源的时间值，所以第一差值组内的各个时间值可以准确反映开关各极触头组的接通同步性。同样的道理，将第五数值作为第二数值组中的基准值，计算第五数值组与第五数值组的差值，计算第六数值组与第五数值组的差值，计算第七数值组与第五数值组的差值，计算第八值组与第五数值组的差值，将这些差值分别除以设备频率值可以获得一个以时间为单位的时间值，所得的时间值标定的是对应相的触头组比A相的触头组提前或者滞后分断第二电源的时间值，所以第二差值组内的各个时间值可以准确反映开关各极触头组的分断同步性。存储计算所得到的第一差值组和第二差值组，可以通过指令cout 将时间值显示于屏幕。
步骤910，改变第一辅助参数组的值、第二辅助参数组的值、第一位置参数的值以及第二位置参数的值。
双电源转换开关的一个转换周期为负载电路从第一电源侧切换到第二电源侧再从第二电源侧切换回第一电源侧。在前半个转换周期中，触头同步性标定是各极触头组断开第一电源的同步性以及各极触头组接通第二电源的同步性。而在后半个转换周期中，触头同步性标定的是各极触头组断开第二电源的同步性以及各极触头组接通第一电源的同步性。因此，在进入下个半个转换周期前需要将获取并存储第一数值组和第二数值组的辅助参数进行变更以满足获取第一数值组和第二数值组的预设条件，以及变更第一、第二辅助参数以正确指示当前负载电路所接入的电源信息。参数的变更方式包括但不限于通过将参数初始化的方式。
