Description

充换电设备和待充换电对象的鉴权方法和*** 技术领域
本发明属于安全认证领域，具体提供一种充换电设备和待充换电对象的鉴权方法和***。
背景技术
为了保证用户的合法权益，电动汽车在进行充换电时需要进行身份信息认证，只有认证通过的电动汽车才能够接受充换电设备的充换电服务。
通常电动汽车的合法鉴权信息被存储到云端或后台服务器，当电动汽车需要充换电时，充换电设备将电动汽车的授权信息发送到云端或后台服务器，在云端或后台服务器进行鉴权。或者当电动汽车需要充换电时，充换电设备先从云端或后台服务器下载电动汽车的合法鉴权信息，然后再对电动汽车进行鉴权。
但是，由于充换电设备与云端或后台服务器之间的通讯容易受外界干扰，所以在电动汽车需要充换电时不能确保充换电设备能够及时将电动汽车的授权信息上传至云端或后台服务器，或者从云端或后台服务器下载电动汽车的合法鉴权信息。
进一步，当多辆电动汽车同时请求充换电时很容易存在充换电冲突。以电动汽车的换电为例，A、B两辆车同时到达换电站并同时连接上换电站WIFI，A车被鉴权通过，但是B车却开到了换电台上。此时，B车服务人员下车点击了开始换电按钮，换电站对B车执行换电作业，导致A车不能被正常换电。或者，A、B两辆车同时到达换电站并同时连接上换电站WIFI，在A车被鉴权通过但驾驶员未下车时，B车驾驶员点击了开始换电按钮，此时换电站对A车执行换电作业，可能会导致事故的发生。
相应地，本领域需要一种新的充换电设备、待充换电对象的鉴权方法来解决上述问题。

具体实施方式
本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非用于限制本发明的保护范围。例如，虽然具体实施方式是结合附图以电动汽车和换电站为例来对本发明的鉴权方法进行详细说明的，但是本发明的鉴权方法还可以适用于其他待充换电对象和其他充换电设备，例如，电动汽车和充电站、电动汽车和充换电站、电动自行车和充电站等。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
本发明的充换电设备和待充换电对象的鉴权方法主要包括以下步骤：待充换电对象向充换电设备发送第一鉴权信息；充换电设备对第一鉴权信息进行验证；在第一鉴权信息验证通过之后，待充换电对象的充换电操作人员向充换电设备提供第二鉴权信息；充换电设备对第二鉴权信息进行验证，在第二鉴权信息验证通过之后，允许充换电设备向待充换电对象提供充换电服务。
下面结合附图，以换电站和电动汽车之间的鉴权方法为例来对本发明的充换电设备和待充换电对象的鉴权方法进行详细地说明，即将电动汽车作为待充换电对象，将换电站作为充换电设备。
如图1所示，换电站和电动汽车之间的鉴权方法主要包括：步骤S110，电动汽车向换电站发送第一鉴权信息；步骤S120，换电站接收并验证第一鉴权信息；步骤S130，充换电操作人员向换电站提供第二鉴权信息；步骤S140，换电站接收并验证第二鉴权信息；步骤S150，换电站对电动汽车执行换电作业。
具体地，在步骤S110中，电动汽车向换电站发送第一鉴权信息。该第一鉴权信息是电动汽车的身份信息(电动汽车ID)，该电动汽车的身份信息可包含但不限于电动汽车的车架号(VIN码)、发动机编号(电动机编号)、电池编号、预设并存储在电动汽车里的专用识别编码、或其他可以识别电动汽车身份的编号等。对信息内容的改变和调整并不偏离本发明的基本原理，因此也将落入本发明的保护范围之内。 进一步，电动汽车优选地通过WIFI通信向换电站发送第一鉴权信息，或者本领域技术人员还可以根据需要，使电动汽车通过其他通信方式向换电站发送第一鉴权信息，例如，ZIGBEE通信和蓝牙通信。
具体地，在步骤S120中，换电站接收电动汽车发出的第一鉴权信息，并将该第一鉴权信息与预存的第一鉴权核对信息进行匹配。该预存的第一鉴权核对信息是预存的电动汽车的身份信息。当第一鉴权信息与第一鉴权核对信息相匹配时，则换电站执行步骤S130；当第一鉴权信息与第一鉴权核对信息不匹配时，则换电站终止当前操作。本领域技术人员能够理解的是，为了避免第一鉴权信息传输过程中数据丢失，可以使电动汽车向换电站发送多份同样的第一鉴权信息，当换电站接收到的第一份第一鉴权信息与第一鉴权核对信息不匹配时，换电站将第二份第一鉴权信息与第一鉴权核对信息进行匹配，直至匹配成功或者遍历所有的第一鉴权信息为止。
具体地，在步骤S130中，在第一鉴权信息与第一鉴权核对信息相匹配时，即在第一鉴权信息验证通过之后，换电站将该验证结果告知充换电操作人员，充换电操作人员向换电站提供第二鉴权信息。本领域技术人员能够理解的是，该充换电操作人员可以是任何合法的人员，例如电动汽车的驾驶员、换电站的代客充换电的服务人员，同样第二鉴权信息可以是充换电操作人员的身份信息，也可以是换电站发送的验证码。
作为实施例一，充换电操作人员是电动汽车的驾驶员，第二鉴权信息是驾驶员的身份信息，该身份信息包括但不限于驾驶员的身份证号、虹膜信息、指纹信息、面部信息和手机号。
作为实施例二，充换电操作人员是换电站的服务人员，第二鉴权信息是服务人员的身份信息，该身份信息包括但不限于服务人员的身份证号、员工号、虹膜信息、指纹信息、面部信息和手机号。
作为实施例三，充换电操作人员是电动汽车的驾驶员，第二鉴权信息是第一鉴权信息验证通过之后换电站生成的随机验证码。换电站将该随机验证码发送给当前电动汽车或者与当前电动汽车关联的设备，通知驾驶员。该关联的设备可以是任何能够与电动汽车进行关联的设备，如驾驶员的手机、平板电脑或其它移动终端。
作为实施例四，充换电操作人员是电动汽车的服务人员，第二鉴权信息是第一鉴权信息验证通过之后换电站生成的随机验证码。换电站将该随机验证码发送给当前电动汽车或者与当前电动汽车关联的设备，通知服务人员。该关联的设备可以是任何能够与电动汽车进行关联的设备，如服务人员的手机、平板电脑或其它移动终端。
具体地，在步骤S140中，换电站将接收到的第二鉴权信息与预存的第二鉴权核对信息进行匹配。当第二鉴权信息与预存的第二鉴权核对信息相匹配时，则换电站执行步骤S150；当第二鉴权信息与第二鉴权核对信息不匹配时，则换电站终止当前操作。
与步骤S130中实施例一相对应地，第二鉴权核对信息是驾驶员的身份信息(例如驾驶员的手机号)。当驾驶员的身份信息与预存的驾驶员的身份信息相匹配时，换电站执行步骤S150，否则不执行。
与步骤S130中实施例二相对应地，第二鉴权核对信息是服务人员的身份信息(例如服务人员的工号)，当服务人员的身份信息与预存的服务人员的身份信息相匹配时，换电站执行步骤S150，否则不执行。
与步骤S130中实施例三相对应地，第二鉴权核对信息是随机验证码时，驾驶员通过电动汽车内的显示器或手机获取该验证码，并将该验证输入到换电站。当驾驶员输入的验证码与换电站发出的验证码一致时，换电站执行步骤S150，否则不执行。
与步骤S130中实施例四相对应地，第二鉴权核对信息是随机验证码时，服务人员通过电动汽车内的显示器或手机获取该验证码，并将该验证输入到换电站。当服务人员输入的验证码与换电站发出的验证码一致时，换电站执行步骤S150，否则不执行。
此外，本领域技术人员应当理解的是，上文所述的预存的第一鉴权核对信息和预存的第二鉴权核对信息都是合法的鉴权信息。
进一步，在步骤S150中，在第二鉴权信息验证通过之后，换电站对电动汽车进行换电作业，直至换电完成电动汽车驶离换电站。
本领域技术人员能够理解的是，在本发明的优选实施方案中，通过将电动汽车的身份信息和服务于该电动汽车的驾驶员或服务人员的身份信息进行双重验证，保证了换电站只能够对驾驶员或服务人员操作的当前电动汽车进行换电作业。因此，本发明能够在不增加硬件成 本的前提下，避免了多辆电动汽车同时向换电站发送换电请求时，发生错误的换电行为的问题，保证了换电过程的安全性和合法用户的合法权益。
进一步，由于换电站从云端或远程端获取授权信息或将第一鉴权信息和第二鉴权信息上传至云端或远程端受无线网络的影响，即当信号受到外界干扰时，换电站和云端、远程端的信息传输不够稳定并且传输速率有限。所以在执行步骤S110之前，还包括图2中所示的：步骤S210，服务器生成授权信息；步骤S220，服务器将授权信息发送给电动汽车。
具体地，在步骤S210中，服务器可以是任何能够生成授权信息的设备，如电脑、云端服务器。授权信息包括换电站ID、电动汽车ID、充换电操作人员ID和授权有效时间四类。具体地，服务器对上述四类信息使用MD5算法(消息摘要算法第五版)进行摘要，获得信息md5Data＝MD5(换电站ID，电动汽车ID，充换电操作人员ID，授权有效时间)。进一步，服务器将自身的私钥private key和MD5Data通过RSA算法(公钥加密算法)进行加密，得到第五类信息——enData：RSA(md5Data，private key)。上述的五类信息即为服务器生成的最终授权信息。由于MD5算法和RSA算法是本领域技术人员所熟知的算法，所以在此不做过多说明。此外，本领域技术人员还可以根据需要，使服务器采用任何可行的摘要算法和加密算法获得最终的授权信息。
具体地，在步骤S220中，服务器既可以通过无线通讯的方式将授权信息发送给电动汽车，也可以通过有线通讯的方式将授权信息发送给电动汽车。示例性地，该无线通讯方式可以是WIFI通讯，该有线通讯方式可以数据线传输数据的通讯方式。
进一步，在执行步骤S110的同时、之前或之后，执行步骤S230，电动汽车将授权信息发送给换电站。从而换电站能够根据接收到的授权信息对第一鉴权信息和第二鉴权信息进行验证。
本领域技术人员能够理解的是，与步骤S210和步骤S310相对应地，在执行步骤S120的过程中，换电站在对第一鉴权信息进行验证之前需要通过RSA算法对授权信息进行解密，并且在第一鉴权信息进行验证时需要对RSA解密后的授权信息进行验证。由于RSA算法是本领域技术人员所熟知且常用的算法，所以此处不再进行过多说明。
此外，如图3所示，对步骤S210和步骤S220可替代地，步骤S310，服务器生成授权信息；步骤S320，服务器将授权信息发送给换电站。步骤S310中授权信息的生成与步骤S210中授权信息的生成相同。步骤S320中服务器将授权信息发送给换电站的通讯方式与步骤S220中服务器将授权信息发送给电动汽车的通讯方式相同。
本领域技术人员能够理解的是，相对于现有技术中换电站对电动汽车进行鉴权时将第一鉴权信息和第二鉴权信息上传到云端服务器或后台服务器进行鉴权的技术方案而言，本发明借助步骤S210至步骤S230将授权信息先存储到电动汽车上然后由电动汽车发送给换电站或步骤S310至步骤S320将授权信息直接存储至换电站，然后将第一鉴权信息和第二鉴权信息直接在换电站内进行验证的技术方案，能够保证鉴权过程中通信的可靠性。
下面结合图1、图2和图4来对电动汽车的换电过程进行举例说明。
服务器1生成授权信息，并将该授权信息发送给电动汽车2。在电动汽车2和换电站3建立WIFI通信连接之后，电动汽车2向换电站3发送电动汽车ID和授权信息。换电站3接收到电动汽车ID和授权信息之后，判定授权信息中的换电站ID是否为自身的ID，判断授权信息中的电动汽车ID是否与当前电动汽车的ID一致，判断当前时间是否在有效时间之内。当上述信息均满足要求时，则换电站3发送随机验证码到电动汽车2或与电动汽车2关联的手机上通知驾驶员或服务人员。服务人员将该验证码输入到换电站3上，当换电站3判定输入的验证码与发出的验证码一致时，换电站3对电动汽车2执行换电作业。
下面结合图1、图2和图5来对电动汽车的换电过程进行举例说明。
服务器1生成授权信息，并将该授权信息发送给换电站3。在电动汽车2和换电站3建立WIFI通信连接之后，电动汽车2向换电站3发送电动汽车ID。换电站3接收到电动汽车ID之后，判定授权信息中的换电站ID是否为自身的ID，判断授权信息中的电动汽车ID是否与当前电动汽车的ID一致，判断当前时间是否在有效时间之内。当上述信息均满足要求时，则换电站3发送随机验证码到电动汽车2或与电动汽车2关联的手机上通知驾驶员或服务人员。服务人员将该验证码输入到换电 站3上，当换电站3判定输入的验证码与发出的验证码一致时，换电站3对电动汽车2执行换电作业。
本领域技术人员能够理解的是，本发明的鉴权方法不仅限于换电站对电动汽车的鉴权，其还可以应用于其他设备上，例如，电动汽车与充电站之间、电动汽车与充换站之间以及其他用电设备与充电设备之间。
本领域技术人员能够理解的是，本发明的鉴权方法除了上述的换电站3对电动汽车2进行鉴权的方式外，还可以是电动汽车2对换电站进行鉴权的方式。具体地，服务器1生成合法鉴权信息，并将该鉴权信息发送给电动汽车2。在电动汽车2需要进行充换电时，电动汽车2向换电站3发送鉴权邀请信息，换电站3接收到鉴权邀请信息后向电动汽车2发送鉴权请求信息。电动汽车2对换电站3进行鉴权，鉴权通过后电动汽车2向换电站3发送鉴权通过提示信息，换电站3在接收到鉴权通过提示信息后向电动汽车2发送验证码，进而操作人员能够将得到的验证码输入换电站3，当换电站3接收到的验证码与发出的验证码相同时，允许换电站3为电动汽车2提供换电服务。
此外，本领域技术人员还可以根据需要对本发明上述的优选实施方案进行适当调整，调整之后的技术方案仍将落入本发明的保护范围。示例性地，步骤S110中的第一鉴权信息是由服务器1生成并发送到电动汽车2上的特殊识别码。步骤S120中的第一鉴权核对信息由服务器1生成并发送到换电站3上，或者由服务器1生成并发送到电动汽车2上，然后由电动汽车2发送到换电站3上。本领域技术人员能够理解的是，由服务器1生成并存储到电动汽车2上的第一鉴权信息，相对于以电动汽车2自身ID作为第一鉴权信息而言更加安全，避免了非法电动汽车伪造假的电动汽车ID欺骗换电站进行换电的现象。
在另一方面，根据上述实施例本发明还提供了一种充换电设备和待充换电对象的鉴权***，该鉴权***主要包括第一鉴权装置、第二鉴权装置、和控制器。第一鉴权装置设置在待充换电对象上，用于向充换电设备发送第一鉴权信息；第二鉴权装置设置在充换电设备上，用于将第一鉴权信息进行验证。在第一鉴权信息验证通过之后，第二鉴权装置接收充换电操作人员提供的第二鉴权信息，并将第二鉴权信息和预存的第二鉴权核对信息进行比较，在第二鉴权信息验证通过之后，允许 充换电设备向待充换电对象提供充换电服务。与上述实施例对应的，该待充换电对象是电动汽车，该充换电设备是换电站。进一步，该控制器存储有程序指令，该程序指令被控制器执行时能够实现步骤S110至步骤S150和步骤S230。
在又一方面，根据上述实施例本发明还提供了一种充换电设备的鉴权方法，该鉴权方法主要包括以下步骤：接收第一鉴权信息；将第一鉴权信息进行验证；在第一鉴权信息验证通过后，接收充换电操作人员提供的第二鉴权信息；将第二鉴权信息进行验证，在第二鉴权信息验证通过之后，允许充换电设备提供充换电服务。以及根据上述实施例本发明还提供了一种充换电设备的鉴权***，该鉴权***包括控制器，该控制器存储有程序指令，该程序指令被控制器执行时能够实现上述充换电设备的鉴权方法的所有步骤。
