图2为本发明的具体实施例中一种数据存储装置的复位装置的示意图；
图3为本发明的具体实施例中一种数据存储装置的复位系统的示意图。
具体实施方式
下面，结合附图以及具体实施方式，对本发明做进一步描述：
参照图1，本实施例提供一种数据存储装置的复位方法，包括如下步骤：
步骤S1，获取成像设备向数据存储装置发送的指令。需要说明的是所述数据存储装置可为耗材芯片；所述成像设备向数据存储装置发送的指令可以包括读指令及写指令。数据存储装置中包括第一地址及第二地址。所述第一地址存储的数据可为除储耗材的消耗量的之外数据，例如序列号数据、区域版本数据、粉盒型号数据、厂家代码数据、生产日期数据、型号数据、特性参数数据等中的一种或者多种。作为优选方案，本实施例中所述第一地址的数据为零。所第二地址可 存储耗材的消耗量，例如碳粉盒中碳粉的消耗量。
步骤S2，获取数据存储装置中第一地址的数据。需要说明的是，本实施例中步骤S1与步骤S2的顺序可以互换。
步骤S3，判断所述指令是否为读取数据存储装置中第二地址的数据的指令。若是则执行步骤S4，若否则执行步骤S1。所述指令可以包括读第一地址或第二地址的数据的指令、向第一地址或第二地址写入数据的指令、或者重新握手命令等。
步骤S4，若步骤S3的判断结果为是，则切断成像设备与数据存储装置的通信，并将步骤S2获取的第一地址的数据发送至成像设备。将第一地址的数据发送至成像设备是为了成像设备能正常的对第一地址的数据进行解密识别，使得打印机将数据存储装置判断为合法的，并根据第一地址的数据将数据存储装置判断为全新的数据存储装置。切断成像设备与数据存储装置的通信是为了防止数据存储装置中存储于第二地址的数据发送至成像设备，避免成像设备记录数据存储装置中耗材的实际消耗量。
若步骤S3的判断结果为是，在步骤S4还可以包括如下子步骤，步骤S41与步骤S42可以由成像设备端完成：
步骤S41成像设备接收第一地址的数据，由于数据存储装置为合法装置，即其可被成像设备验证通过。若成像设备为打印机时，所述数据储存装置可为芯片，通常待复位的数据存储装置可为原装产品，因此成像设备在接收第一地址的数据之后能正常的验证通过。
步骤S42，成像设备对第一地址的数据进行验证之后生成复位数 据。由于成像设备与数据存储装置的通信被切断，所以此次成像设备没有获取数据存储装置的第二地址的数据，即实际耗材的消耗量。
步骤S5，接通成像设备与数据存储装置的通信，通过成像设备对数据存储装置的进行复位。由于第一地址的数据能正常被成像设备验证验证，因此成像设备可将数据存储装置认为是全新的数据存储装置，从而将数据存储装置的耗材的消耗量的初始值作为复位数据发送出去，此时将成像设备与数据存储装置接通，复位数据则会被发送至数据存储装置的第二地址，并将第二地址存储的数据覆盖，从而完成复位。完成复位之后可以关闭复位装置，或者断开复位装置与成像设备的通信，当数据存储装置通过耗材盒安装于成像设备后，启动成像设备数据存储装置可正常与成像设备通信。当需要复位时再启动复位装置即可。需要说明的是，步骤S1-S5均可由除了成像设备及数据存储装置之外的复位装置实现，当然也可由数据存储装置实现。
作为优选方案，步骤S5中所述通过成像设备对数据存储装置的进行复位的步骤包括如下子步骤：
步骤S51，成像设备根据将写入数据存储装置中第二地址的数据的指令复位数据发送至数据存储装置。成像设备在生成复位数据之后会产生写入的指令，然后将复位数据写入数据存储装置。由于复位数据是针对耗材的消耗量进行复位，所以复位数据是被写入第二地址。
步骤S52，将第二地址的数据替换成复位数据。
作为优选方案，步骤S5中所述对第一地址的数据进行验证之后生成复位数据的步骤包括如下子步骤：
步骤S53，成像设备对第一地址的数据进行验证之后，自动将第二地址的消耗量数据识别为原始数据。所述原始数据可为零或者零之外的其他自然数。由于第一地址的数据中包含有全零的数据，所以成像设备可以将第二地址存储的消耗量数据记录为零，即数据存储装置被可被打印机识别为全新的装置。
步骤S54，成像设备将原始数据通过计算变成复位数据。所述计算的过程可为将原始数据加一或者加一之外的其他自然数。例如可以通过成像设备使用一次数据存储装置来实现将原始数据计算成复位数据。需要说明的是，所述原始数据与复位数据分别可为二进制、十进制或者十六进制的数据。
作为优先方案，在成像设备向数据存储装置发送读取第二地址的数据的指令之前包括如下步骤：成像设备向数据存储装置发送读取第一地址的数据的指令；并验证第一地址的数据为合法数据。由于待复位数据存储装置与成像设备通常是原装配套的，所以第一地址的数据为合法数据。
综上所述，以上实施例中成像设备本身知道数据存储装置的加密算法及密钥，所以在复位时无需破解对数据存储装置的加密算法，就能实现对数据存储装置复位，因此本发明的数据存储装置的复位方法及应用该方法进行复位的复位装置及复位系统的复位效率及成功率均非常高。
参照图2，本发明的实施例还提供一种数据存储装置的复位装置，该装置包括：
第一获取模块1，其用于获取成像设备向数据存储装置发送的指令；
第二获取模块2，其用于获取数据存储装置中第一地址的数据；
监听模块3，其与第一获取模块及第二获取模块均连接；该监听模块用于监听成像设备发送的指令，并判断所述指令是否为读取数据存储装置中第二地址的数据的指令；
接口控制模块4，其与监听模块连接，该接口控制模块用于控制成像设备与数据存储装置通信的通断；当监听模块判断的结果为所述指令是读取数据存储装置中第二地址的数据的指令时，切断成像设备与数据存储装置的通信，并通过监听模块将第一地址的数据发送至成像设备；当第一地址的数据发送至成像设备之后，接通成像设备与数据存储装置的通信，通过成像设备对数据存储装置的进行复位。所述第一地址的数据为零；所述第二地址的数据为耗材消耗量的数据。复位装置能够监听、干扰成像设备与数据存储装置通信信道上的通信数据。
参照图3，本发明的实施例还提供一种数据存储装置的复位系统，包括成像设备(图中未视出)、复位装置100及数据储存装置200，所述复位装置100与成像设备及数据储存装置200均连接.所述复位装置可以为以上实施例所述的数据存储装置的复位装置。所述复位装置100的监听模块与成像设备连接，该复位装置的接口控制模块与监听模块、成像设备及数据存储装置均连接。所述成像设备可以通过IIC总线300与复位装置100及数据存储装置200连接。
需要说明的是，以上实施例所述的复位方法、复位装置及复位系统可以用于对已经使用完毕的数据存储装置进行复位，例如可以对耗材容量已经打完的耗材芯片复位成耗材容量为满的耗材芯片。
以下以数据存储装置为芯片、成像设备为打印机为例，对本发明的数据存储装置的复位方法，复位装置及复位系统分别进行说明。
在打印机上电之后首先通过复杂的算法来验证芯片的合法性，合法性通过之后打印机通过特定的指令访问芯片内存储的与粉盒相关的数据，例如打印机可能先会读取芯片内存储的区域版本数据、序列号的数据及芯片内其他区域的数据且这些区域的数据部分全是零，即打印机会先读取到第一地址存储的数据，可以通过复位装置将是零的数据获取过去。然后打印机再读取碳粉的消耗量(第二地址存储的数据)并记录。
为了不让打印机记录芯片已存储的耗材的消耗量，需要在芯片复位之前让打印机不能读取到原装复位芯片内存储的耗材的消耗量，则需要借助复位装置监听并记录所有打印机下发指令和芯片返回的数据。由于打印机在读取芯片中存储的耗材的消耗量之前会读取芯片内其他地址的数据且该数据为零，即第一地址。当复位装置监听到打印机需要读取芯片内耗材的消耗量时，即第二地址的数据，复位装置首先切断芯片和打印机的通信并将其从芯片获取的第一地址的数据返回给打印机，由于芯片为原装芯片，所以打印机知道芯片加密算法和密钥，可以通过对称加密使得打印机正常解密第一地址的数据。由于第一地址的数据为零，当打印机解密之后则会记录原装芯片内存储的 耗材的消耗量为0或者原始数据，即表示该芯片为全新芯片或者耗材剩余量为100％。
例如当在让打印机记录原装复位芯片的耗材余量为0之后，可以让打印机打印一张纸，此时打印机会往原装芯片内写入耗材的消耗量，由于打印上电记录了芯片的耗材的消耗量为0，所以打印一张纸之后打印机会往芯片内第二地址内写1，从而将原来已经耗尽的消耗量数值改写成1实现复位。
综上所述本发明提供的复位方法、复位装置是利用打印机和原装芯片通信规律以及加密算法实现对原装芯片的复位，即，由于芯片是原装芯片，所以打印机可以验证第一地址的数据，即芯片是合法的，打印机可以与芯片顺利通信并顺利的将复位数据写入芯片，所以所述复位方法无需对芯片的加密算法进行破解就实现对原装芯片复位，进而能有效的提高复位的效率与成功率。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本发明权利要求的保护范围之内。
需要说明的是：以上所述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
