(4)协议识别模块23：此模块通过微控制器对DP3点的电压的判断，当DP3电压大于5.64且小于6.36时，识别当前为ChaoJi标准；当DP3电压大于7.54且小于8.45时，识别当前为(GB2015)标准；当DP3电压大于1.86且小于2.14时，识别当前为CHAdeMO标准。

在图12的基础上，所述开关状态检测系统还可以包含有开关控制单元：通过微控制器13控制开关的打开与闭合。
基于上述开关状态检测系统，本申请应用实例还提供一种基于该开关状态检测系统实现的开关状态检测方法，参见图13，具体包含有如下内容：
S1.设备上电之后等待CCU(车载充电控制器)发送闭合Sv命令。CCU发送闭合命令，微控制器单元控制Sv关闭，开关控制单元执行Sv关闭。
S2.测量DP3点电压值，对DP3电压进行滤波，得到稳定的电压值，微控制器控制读取Sv闭合前记录当前Vdp3_last电压，当控制Sv闭合后微控制器读取电压为Vdp3，如Vdp3_last等于Vdp3或者不在5.64V<Vdp3<6.36V(Chaoji)、7.54V<Vdp3<8.45V(GB2015)、1.86V<Vdp3<2.14V(CHAdeMO)范围内，则视为Sv关闭失败，Sv状态为打开。
S3.如果DP3电压值在上述范围内，则视为Sv关闭成功，根据电压值确定当前需要执行的标准如上所述。
S4.当标准确定后，等待CCU发送S2'关闭命令，CCU发送关闭S2'命令，测量DP2电压，滤波并记录当前DP2电压值。
微控制器控制S2'关闭，开关控制器执行S2'关闭后，测量DP2电压，滤波，如果控制关闭S2'之后的DP2电压不等于控制S2'关闭之前的，则认定S2'关闭，否则认为S2'关闭失败。
S5.当S2'关闭后，等待CCU关闭S2命令，CCU发送关闭S2命令，测量DP2电压，滤波，微控制器会根据不同的协议控制S2关闭的位置，微控制器控制关闭S2，开关控制器执行关闭S2。测量DP2电压，滤波，如果控制关闭S2之后的DP2电压不等于控制S2'关闭之前的，则认定S2关闭，否则认为S2关闭失败。
其中，S2中涉及的滤波算法如下：
为了保证数据的准确性，采用了两种不同的滤波算法，之后对其输出值进行比较，如果两个方法输出的数值的差值小于设定误差阈值，则认为此次数据正确。
(1)均值算法
假设DP点(DP2、DP3)电压Vdp，取DP点的n个数据，n个数据和为Vdp_sum,n个数据的平均值为Vdp_ave
Vdp_sum＝Vdp 1+Vdp 2+Vdp 3+......+Vdp n-1+Vdp n
Vdp_ave＝Vdp_sum/n；
(2)中值滤波算法
假设DP点(DP2、DP3)电压Vdp，取DP点的n个数据；
1.首先将DP点的n个电压值暗按照从小到大或者从大到小的顺序排列，得到新的n个数据组合；
2.取N数据中间的值；
3.中值为Vdp_mid：
如果N为偶数：Vdp_mid＝(Vdp n/2+Vdp (n/2)+1)/2
如果N为基数：Vdp_mid＝(Vdp (n/2)+1)
3.6.4两种滤波算法之后得到两个值Vdp_ave和Vdp_mid,两个值相减，如果差值大于设定的阈值，则认定数据错误，抛弃此组数据，微控制器从滤波模块内重新获取n个数据进行上述算法。重新获取是指：采集DP点的一组n个数据，并进行滤波计算，如果数据错误，则重新采集新的一组n个数据。
从硬件层面来说，为了现有的检测点电压滤波方式存在的无法验证电压滤波的有效性，因此无法保证根据滤波后电压进行后续控制或检测的准确性等问题，本申请提供一种用于实现所述电路检测点电压滤波方法或开关状态检测方法中的全部或部分内容的电子设备的实施例，所述电子设备具体包含有如下内容：
