Description

存储芯片复位方法、复位装置及复位系统 技术领域
本发明涉及存储芯片技术领域，具体涉及一种能应用于成像设备(例如复印机、打印机、传真机、多功能文字处理机等)的存储芯片复位方法及应用了该复位方法的复位装置及复位系统。
背景技术
随着打印机等成像设备的不断普及，应用于成像设备的碳粉盒或者墨盒及安装于碳粉盒或者墨盒的存储芯片的消耗量不断提高。若碳粉盒或者墨盒中的碳粉或者墨水消耗完了之后，将安装在碳粉盒或者墨盒上的存储芯片(芯片包括IC(integrated circuit)以及对应的外围电路)也连同废碳粉盒或者墨盒一同丢弃，不能被重复利用，则会造成很大的浪费。
目前芯片回收者通常采用对旧的存储芯片进行破解之后，才能对废弃后的旧芯片进行复位，实现对废弃旧芯片的重复利用。存储芯片的合法性以及通信数据的安全性都是建立在加密算法之上。目前应用在打印机耗材领域的加密算法比较常见的有分组加密、公钥加密等。常见的分组加密有DES、3DES、AES等，常见的公钥加密有RSA、ElGamal、ECC等。打印机与存储芯片通信的数据都是经过加密的且加密的密钥是动态的，即每一次通信的密钥都不一样。此外，密钥并不直接传输给打印机而是传输生成密钥的一些参数且该参数是经过 加密的。现有技术若对应加密程度低的存储芯片，其加密算法容易破解则可以实现对存储芯片的重复利用，若存储芯片的加密程度高，破解存储芯片的加密算法难度大，则不能实现对存储芯片复位，仍然会造成旧芯片的浪费。

优选地，所述指令包括写指令与读指令。
优选地，所述待复位芯片的耗材消耗量已经达到最大阈值；所述功能芯片的耗材消耗量大于或等于零，且小于最大阈值。
优选地，在所述接通成像设备与功能芯片的步骤之后，在所述获 取成像设备发送的指令步骤之前，还包括如下步骤：

附图说明
图1为本发明的实施例中一种存储芯片复位方法流程图；
图2为本发明的实施例中一种存储芯片复位装置示意图；
图3为本发明的实施例中一种存储芯片复位系统示意图。
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：
结合图1，本实施例提供一种存储芯片的复位方法，包括如下步骤：
步骤S1，断开成像设备与待复位芯片的通信，接通成像设备与功能芯片，使得功能芯片能与成像设备进行通信。待复位芯片及功能芯片均可通过IIC总线与成像设备连接。可通过一复位装置控制待复位芯片及功能芯片是否与成像设备通信。例如在对待复位芯片进行复位之前，成像设备需要与功能芯片通信生成复位数据并不能与复位芯片通信，避免成像设备生成错误的复位数据。
需要说明的是，所述待复位芯片的耗材消耗量已经达到最大阈值；所述功能芯片的耗材消耗量大于或等于零，且小于最大阈值。例如：所述功能芯片可为全新的芯片，且其能被成像设备验证通过；所述待复位芯片为使用过的芯片，如该待复位芯片代表耗材容量的数据为零，且待复位芯片也能被成像设备验证通过。
步骤S2，获取成像设备发送的指令。成像设备在与功能芯片通信过程中会生成读指令或者写指令，并往功能芯片发送。此时在所述指令被发送至功能芯片之前可通过复位装置来获取成像设备发送的指令，并执行步骤S3。
步骤S3，判断所述指令是否为写耗材消耗量的数据的指令。若是则执行步骤S4；否则允许将指令写入功能芯片，因为成像设备在往功能芯片写入耗材消耗量的数据之前先会验证功能芯片的合法性以及读取芯片的序列号等中的一种或者多种操作。
步骤S4，若是则在所述耗材消耗量的数据被写入功能芯片之前断开成像设备与功能芯片的通信。此步骤可以防止将耗材消耗量的数据写入功能芯片，从而为待复位芯片进行复位提供复位数据。因为成像设备在没有成功将耗材消耗量写入功能芯片时，会再次向功能芯片发送写入耗材消耗量的数据。
步骤S5，向成像设备发送写入失败的指令。可以在所述耗材消耗量的数据被写入功能芯片之前执行步骤S5，也可以在所述耗材消耗量的数据被写入功能芯片之后，在断开成像设备与功能芯片的通信之前执行步骤S5。也可以在在断开成像设备与功能芯片的通信之后执行步骤S5。写入失败的指令可由复位装置生成，或者由功能芯片生成，例如可通过复位装置使得成像设备写入功能芯片的数据的地址超过范围，功能芯片则会生成写入失败的指令。
步骤S6，接通成像设备与待复位芯片，使得成像设备与待复位芯片通信；通过成像设备对待复位芯片进行复位。由于成像设备在与待复位芯片通信之前，已经根据功能芯片生成了耗材消耗量的数据，且该数据没有被成功的写入任何一个芯片，因此在接通成像设备与待复位芯片之后，该耗材消耗量的数据会被成功写入待复位芯片，从而完成复位。
作为优选方案，在步骤S6中所述通过成像设备对待复位芯片进行复位的过程包括如下步骤：
步骤S61，成像设备接收到写入失败的指令。
步骤S62，根据所述写入失败的指令成像设备再次发送所述写耗材消耗量的数据的指令。
步骤S63，将未写入功能芯片的耗材消耗量的数据写入待复位芯片；由于在步骤S63之前，功能芯片与成像设备的通信已经断开，并且待复位芯片与成像设备进行通信，故成像设备再次发送的写耗材消耗量的数据的指令会被写入待复位芯片。
步骤S64，在将耗材消耗量的数据写入待复位芯片之后，待复位芯片会生成写入成功的指令，并将发送写入成功的指令给成像设备实现复位。此时待复位芯片接收到的耗材消耗量的数据实际是来自于功能芯片，假如功能芯片为全新的芯片，该功能芯片在与成像设备通信后打印了一页纸，那么耗材消耗量为一，此时写入待复位芯片的耗材消耗量的数据为1，相当于待复位芯片的耗材只使用了一页，假如一个全新的芯片能打印10000页，该待复位芯片在复位之后的耗材还剩余9999页。
作为优选的方案，所述接通成像设备与待复位芯片的步骤在所述根据所述写入失败的指令成像设备再次发送所述写耗材消耗量的数据的指令之前，且在所述断开成像设备与功能芯片的通信的步骤之后。
作为优选的方案，所述在将耗材消耗量的数据写入待复位芯片之 后，待复位芯片发送写入成功的指令给成像设备实现复位的步骤包括如下子步骤：
待复位芯片在接收到耗材消耗量的数据之后，判断是否写入成功；
若是，则生成写入成功的指令，并将该指令发送至成像设备，完成复位；
否则，生成写入失败的指令，并将该指令发送至成像设备，成像设备则继续发送写入耗材消耗量的数据的指令。待复位芯片在写入耗材消耗量的数据失败之后还可能执行如下步骤：成像设备将该芯片判定为非法芯片，并禁止该复位芯片与成像设备通信。
作为优选方案，在所述接通成像设备与功能芯片的步骤之后，在所述获取成像设备发送的指令步骤之前，还包括如下步骤：
成像设备验证所述功能芯片的合法性；
若功能芯片为合法芯片时，所述功能芯片能通过成像设备的验证；
在所述功能芯片验证通过之后，成像设备使用功能芯片；
根据使用功能芯片的操作成像设备向功能芯片发送的指令。所述成像设备使用功能芯片的方式可为，成像设备通过功能芯片执行成像操作，此时会消耗耗材，并记录耗材消耗量，例如可为打印机利用功能芯片执行打印一页纸，并记录耗材消耗量为1。
综上，本发明是通过监控成像设备与功能芯片通信状态及发送的数据，将功能芯片的耗材消耗量的数据写入到待复位芯片内，使得待 复位芯片的耗材消耗量为功能芯片的，完成复位，在复位的过程中无需知道待复位芯片的加密算法。
作为另一较佳实施例，参照图2，本发明还提供一种存储芯片复位装置100，包括：监听模块1及与监听模块1连接的控制器2。所述监听模块1包括获取单元11、判断单元12及发送单元13；所述获取单元11、判断单元12及发送单元13分别可以与控制器2连接。所述获取单元11还可与成像设备连接，该获取单元11用于获取成像设备发送的指令。所述判断单元12用于判断所述指令是否为写耗材消耗量的数据的指令。所述发送单元13还可与成像设备连接，该发送单元13用于在则断开成像设备与功能芯片200的通信之后向成像设备发送写入失败的指令。控制器2可与功能芯片200及待复位芯片300均连接，该控制器2用于控制功能芯片200及待复位芯片300分别与成像设备的通断；在复位启动时断开成像设备与待复位芯片300的通信，接通成像设备与功能芯片200，使得功能芯片200能与成像设备进行通信；若所述判断单元12的判断结果为是时断开成像设备与功能芯片200的通信；在向成像设备发送写入失败的指令之前接通成像设备与待复位芯片300。
作为另一较佳实施例，参照图3，本发明还提供一种存储芯片复位系统，包括成像设备、复位装置100、功能芯片200及复位芯片；
所述复位装置为以上实施例所述的存储芯片复位装置100，该复位装置的监听模块1及控制器2均与成像设备连接；所述功能芯片200及复位芯片分别与所述控制器2连接。所述复位装置100、功能 芯片200及复位芯片分别通过IIC总线400与成像设备连接。连接功能芯片200及成像设备的线路上设置有所述控制器(A/B)2；连接待复位芯片300及成像设备的线路上设置有所述控制器(C/D)2，如此以便控制器2更好的控制功能芯片200、待复位芯片300与成像设备通信的通断。
需要说明的是，本发明的存储芯片复位装置及存储芯片复位系统均可采用以上各实施例所述的存储芯片复位方法对待复位芯片300进行复位。
以下打印机作为成像设备对待复位芯片进行复位为例对本发明的存储芯片复位方法、复位装置及复位系统的工作原理进行说明，待复位芯片为打印完毕的芯片：
所述功能芯片为全新芯片，即该功能芯片没有上过机或者没有打印机过，因此记录耗材消耗量的计数区的数值为零，此时若让打印机打印一张纸则打印机会往功能芯片计数区写1，即耗材消耗量为1。此时将功能芯片与成像设备的通信切断，并将待复位芯片与成像设备通信，然后通过复位装置向成像装置发送功能芯片未能成功将接收到耗材消耗量的数据1写入计数区的指令，打印机在接收到未能成功将接收到耗材消耗量的数据1写入计数区的指令之后重新和功能芯片通信，也即重新握手，此时打印机会继续将上一次未能写进功能芯片耗材消耗量的数据再次发送处理，由于成像设备已经与待复位芯片通信了，所以本次打印机发送的耗材消耗量的数据实际是发送给了待复位芯片完成复位。
综上所述，在复位过程中成像设备往功能芯片写入耗材消耗量数据后，复位装置会向成像设备发送写入失败的指令，成像设备在接收到写入失败的指令后，则成像设备会重新和芯片握手并再次把未写入的数据再次发送给芯片，此时接收成像设备再次发送的未成功写入的耗材容量的数据为待复位芯片。需要说明的是待复位芯片可为原装的旧芯片。所述本发明是通过打印机会重新和芯片握手并把未写入的数据再次发送给芯片之前将与成像设备连接功能芯片切换成待复位芯片，实现复位操作。如此可以无需对待复位芯片的加密算法进行破解即可实现对待复位芯片进行复位，无论该待复位芯片的加密程度有多高或多低均可采用本发明的存储芯片复位方法、复位装置及复位系统进行复位操作，且复位的效率较高。
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。
