Description

一种芯片和墨盒 技术领域
本发明涉及打印成像技术领域，尤其涉及一种读写可改写数据的芯片和墨盒。
背景技术
记录装置，例如打印机、复印机和传真机等，用于将需要记录的信息通过墨水等记录材料记录到纸张等记录介质上。记录装置通常包括记录装置主体和墨盒。墨盒通常以可拆卸地方式安装在记录装置上，并且配置有用于标记墨盒中墨水的消耗量或余量等墨量数据信息的芯片。该芯片通常以可拆卸地方式安装在墨盒上，并且中置有存储元件，以便存储墨水的消耗量或余量等可改写数据，以及其它与墨盒相关的只读数据。当墨盒安装到记录装置上时，墨盒上的芯片会与记录装置建立电连接，并与记录装置进行数据交换。
当记录装置执行了例如打印等消耗墨水的操作之后，需要对芯片中记载的墨水的消耗量或余量等墨量数据进行更新。目前，现有的记录装置通常在将新的墨量数据写入芯片时，以覆盖芯片存储元件中原有的墨量历史数据的方式来完成更新任务。这种数据更新方式存在一定的弊端。如果在记录装置与芯片进行数据通信的过程中，因为传输信号的干扰或者芯片与记录装置的接触不良而导致传输的新的墨量数据出现错误，致使芯片所收到的墨量数据偏离了记录装置所发送的墨量数据，那么在完成更新任务后，芯片存储元件中将存储错误的墨量数据，而且无法恢复为正确的墨量历史数据。
发明内容
为了解决现有技术中在写入错误的墨量数据后导致正确的墨量历史数据无法恢复的技术问题，本发明提出了一种新的芯片和墨盒。
一种芯片，其特征在于，包括：
通信模块，用于所述芯片接收和发送数据；
存储模块，其包含可改写数据存储区，每一所述可改写数据存储区包含至少两个存储单元，且每一所述可改写数据存储区存储一种可改写数据；
写控制器，其连接在所述通信模块与存储模块之间，用于当所述通信模块收到可改写数据时，将该所述可改写数据写入所述可改写数据存储区中与最近一次写入的存储单元不同的一个存储单元中；
读控制器，其连接在所述存储模块与通信模块之间，用于将所述可改写数据存储区中满足特定条件的可改写数据读出，以供所述通信模块发送出去。
根据本发明的实施例，上述写控制器可以向一所述可改写数据存储区中的存储单元轮流写入可改写数据。
根据本发明的另一实施例，上述写控制器可以从一所述可改写数据存储区中与最近一次写入的存储单元不同的存储单元中随机选取一个存储单元，向其写入可改写数据。
根据本发明的实施例，上述读控制器读出一所述可改写数据存储区中所有存储单元中的可改写数据，进行比较，将其中值最大或值最小的可改写数据发送给所述通信模块。
根据本发明的实施例，上述可改写数据包括要写入的数据本体以及与之对应的写次数标识信息，所述写次数标识信息用于标识所述数据本体写入所述存储单元的先后次序。
根据本发明的实施例，上述写控制器比较一所述可改写数据存储区中所有存储单元中可改写数据的写次数标识信息，向其中所述写次数标识信息值最小的存储单元写入新的可改写数据。
根据本发明的实施例，上述读控制器比较一所述可改写数据存储区中所有存储单元中可改写数据的写次数标识信息，将其中满足给定次序条件的存储单元的可改写数据读出，发送给所述通信模块。
其中，所述满足给定次序条件的存储单元可以包括：
最近一次写入可改写数据的存储单元，或者倒数第二次写入可改写数据的存储单元。
根据本发明的实施例，上述一种可改写数据可以包括：
一种类型的一个可改写数据，或者同一类型的两个或两个以上的可改写数据，或者一种类型的可改写数据及其相关联的辅助信息。
此外，本发明还提供一种墨盒，其特征在于，其上安装有上述芯片，所述芯片存储模块中存储有表征此墨盒墨水消耗量或余量的可改写数据。
与现有技术相比，本发明的一个或多个实施例具有如下优点：
本发明实施例所提供的技术方案可以在芯片写入墨量数据等可改写数据时，由写控制器控制将可改写数据写入到与最近一次写入的存储单元不同的另一个存储单元中，从而能够确保芯片的存储模块中保存有最近两次的可改写数据。另一方面，由读控制器读取并比较所有存储单元中的可改写数据，将满足打印机特定条件的可改写数据，如所有可改写数据中值最大的可改写数据，或倒数第二次写入的可改写数据，通过通信模块发送给打印机。因此，当将错误的墨量数据写入芯片的某一存储单元后，芯片的其它存储单元仍然保存有最近一次写入的正确的墨量历史数据，并且能够通过读控制器读出正确的墨量数据，发送给打印机，以便打印机对芯片的墨量进行正确的评估，进而恢复芯片的正常工作。
本发明的其它特征和优点将在随后的说明书中阐述，并且部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。

通信模块210分别连接写控制器230和读控制器240，负责芯片与喷墨打印机的数据通信。通信模块210可以包含保持芯片与喷墨打印机侧的相对应的接触机构相接触的多个端子，以及控制各端子与喷墨打印机侧的对应的电路进行信号交换以传输数据的控制电路，如利用IIC等传输协议进行数据传输的信号分析与控制电路，以完成芯片的数据的发送和接收功能。
通信模块210还可以包含保持芯片与喷墨打印机侧的对应的电路进行无线通信的无线通信信号收发装置，以及控制无线通信信号收发的控制电路，如利用Wi-Fi无线通信模块或NFC近场通信模块，以与喷墨打印机完成数据的发送和接收。
存储模块220分别连接写控制器230和读控制器240，负责存储与墨盒相关的数据信息。这些数据信息包括例如墨量数据等可改写数据，以及例如墨盒生产日期等只读数据。存储模块220可以采用常见的非易失性存储器，如EEPROM、FLASH、铁电存储器等。
需要说明的是，上述可改写数据为喷墨打印机向芯片发送的写入数据，可以进一步地划分为不同的类型：只写一次的数据、只改写一次的数据和可多次改写的数据。例如首次安装日期等属于只写一次的数据，缺墨提示信息等属于只改写一次的数据，以及墨量数据等属于可多次改写的数据。
此外，在本发明中，存储模块220中包含可改写数据存储区，每一个可改写数据存储区包含有至少两个存储单元。每一个可改写数据存储区存储一种可改写数据，且每一个可改写数据存储区中的存储单元彼此独立，互不影响，均可单独、完整地完成一次相对应的可改写数据的存储任务。
图3为本发明实施例一所提供的芯片的存储模块中的一个可改写数据存储区 的存储结构示意图。在该实施例中，存储模块220包含了一个用于存储墨量数据的可改写数据存储区300，其包含两个存储单元：第一存储单元310和第二存储单元320。此外，存储模块220还包含了其它数据存储区400，用于存储例如墨盒生产日期等只读数据。具体地，如图4所示，第一存储单元310中以可改写的形式存储有完整的墨量数据311，第二存储单元320中以可改写的形式存储有完整的墨量数据321。并且墨量数据311和墨量数据321的值彼此相互独立，不会相互影响。
写控制器230连接在通信模块210与存储模块220之间，用于执行写入操作，负责将通信模块210接收到的写入数据写入到存储模块220中。其中，当通信模块210接收到可改写数据时，写控制器230将可改写数据写入一可改写数据存储区中的一个存储单元中。在本实施例中，写控制器230在执行墨量数据写入操作时，轮流向可改写数据存储区300中的第一存储单元310和第二存储单元320写入墨量数据。具体地，写控制器230可以设置寄存器以及存储单元标识位，例如可以用“0”表示上一次执行写入操作时写入第一存储单元310，用“1”表示上一次执行写入操作时写入第二存储单元320。在执行写入操作时，首先将要写入的墨量数据存储到寄存器中，读取存储单元标识位，确定上一次执行写入操作时写入的存储单元，然后再将要写入的墨量数据写入与上一次执行写入操作时写入的存储单元不同的另一个存储单元中，完成本次写入操作。
读控制器240连接在存储模块220与通信模块210之间，用于执行读出操作，负责将存储模块220中存储的数据读出并发送给通信模块210。其中，读控制器240在执行可改写数据读出操作时，将一可改写数据存储区中所有存储单元中的可改写数据读出，进行比较，并将满足特定条件的可改写数据发送给通信模块210。具体地，读控制器240可以设置多个寄存器和一个比较器，用于筛选满足特定条件的可改写数据。在本实施例中，读控制器240在执行墨量数据读出操作时，将可改写数据存储区300中的第一存储单元310中的墨量数据311和第二存储单元320中的墨量数据321分别取出放入第一寄存器和第二寄存器，然后借助比较器比较这两个寄存器中墨量数据的大小，将其中较大的墨量数据作为满足条件的可改写数据，发送给通信模块210，完成本次读出操作。当然，依据设定的特定条件，也可以将其中较小的墨量数据作为满足条件的可改写数据，发送给通信模块210。
在本实施例中，可改写数据存储区包含了两个存储单元。当通信模块接收到记录装置传来的新的可改写数据时，写控制器将此可改写数据写入到可改写数据存储区中与最近一次写入的存储单元不同的存储单元中，也即向两个存储单元轮流写入可改写数据，从而确保芯片的存储模块中保存有最近两次的可改写数据。当需要从芯片中读出可改写数据时，读控制器读取可改写数据存储区中所有存储单元中的可改写数据，并进行比较，将满足喷墨打印机特定条件的可改写数据通过通信模块发送给喷墨打印机。当可改写数据为墨量数据时，芯片的存储模块中保存有最近两次的墨量数据，如此可以有效避免现有技术中将错误的墨量数据写入芯片，覆盖了墨量历史数据后导致无法恢复正确的墨量历史数据的技术问题。
当然，实施例一只公开了本发明的一种实施方式。在该实施例的基础上，还可以有以下诸多变化形式。
实施例二
图5为本发明实施例二所提供的芯片的存储模块中的一个可改写数据存储区的存储结构示意图。在本实施例中，存储模块220包含了一个用于存储墨量数据的可改写数据存储区500，其包含了两个以上的存储单元。为方便起见，图中仅示出三个存储单元：第一存储单元510、第二存储单元520和第三存储单元530。此外，存储模块220还包含了其它数据存储区400，用于存储例如墨盒生产日期等只读数据。与实施例一相同，可改写数据存储区500中的每一个存储单元均用来存储墨量数据，且每一个存储单元均可单独、完整地完成一次墨量数据的存储。
在本实施例中，当写控制器230执行墨量数据写入操作时，可以采用类似实施例一的方式，借助例如“00”形式的存储单元标识位来标记可改写数据存储区500中所有的存储单元，向这些存储单元轮流写入墨量数据。又或者采用另一种方式，即，从不同于最近一次写入墨量数据的存储单元的其它存储单元中随机选取一个存储单元，向其写入最新的墨量数据。对于后一种方式，只需借助一个存储单元标识位标记最近一次写入墨量数据的存储单元，然后从其它存储单元中随机选取一个存储单元，例如选取与被标记的存储单元相邻的下一个存储单元，向其写入墨量数据。
当读控制器240执行墨量数据读出操作时，也可以采用类似实施例一的方式，将可改写数据存储区500中所有存储单元中的墨量数据均读入寄存器，借助比较器对寄存器中所有墨量数据的值进行比较，将满足喷墨打印机特定条件的可改写 数据，例如值最大的墨量数据，发送给通信模块210。当然，依据喷墨打印机特定条件，也可以将值最小的墨量数据作为满足喷墨打印机特定条件的可改写数据，发送给通信模块210。
当然，本实施例所述的可改写数据存储区，也可以是存储其它种类或类型的可改写数据的可改写数据存储区。
实施例三
图6为本发明实施例一所提供的存储单元中的另一种数据结构示意图。在本实施例中，每一个存储单元中以可改写的形式存储着完整的墨量数据和写次数标识信息。其中，写次数标识信息与墨量数据相对应，用于记录墨量数据写入时的先后次序。此处仍以第一存储单元310和第二存储单元320为例进行说明。其中，第一存储单元310存储了最近一次写入的墨量数据311，与墨量数据311对应的写次数标识信息312为50，当向第二存储单元320写入新的墨量数据321之后，与墨量数据321对应的写次数标识信息322更新为51。也即两个存储单元所存储的写次数标识信息分别表示了两个墨量数据写入的先后次序。
综上所述，当存储单元中同时存储有可改写数据和写次数标识信息时，写控制器230执行写入操作，可以通过比较可改写数据存储区300中每一个存储单元中的写次数标识信息，确定最近一次写入可改写数据的存储单元，并将要写入的可改写数据写入到不同于最近一次写入可改写数据的存储单元的其它存储单元中，例如写次数标识信息的值最小的存储单元中。
同理，当存储单元中同时存储有可改写数据和写次数标识信息时，读控制器240执行读出操作时，可以读出可改写数据存储区300中所有存储单元中的写次数标识信息，从中确定满足给定次序条件，例如最近一次或者倒数第二次写入可改写数据的存储单元，将其中的可改写数据发送给通信模块210。
以上三个实施例主要介绍的是喷墨打印机向芯片写入或者读出一种可改写数据的情况，实际工作中远不限于此，喷墨打印机可以向芯片同时写入或者同时读出两种或两种以上的可改写数据。
实施例四
针对需要向芯片同时写入两种或两种以上可改写数据的情况，例如同时写入墨量数据和缺墨提示信息的情况，芯片的存储模块中可以包含多个可改写数据存储区。每一个可改写数据存储区用于存储一种可改写数据。每一个可改写数据存 储区可以是如图3或图5所示的存储结构。
本实施例所述的一种可改写数据，可以是某一类型的一个可改写数据，如墨量数据，也可以是属于同一类型的两个或两个以上的可改写数据，如墨量数据正码存储数据和墨量数据反码存储数据，或者，也可以是某一类型的可改写数据及其相关联的辅助信息，该辅助信息也可以被改写，如墨量数据和与该墨量数据相对应的写次数标识信息。
以向芯片同时写入墨量数据和缺墨提示信息为例。其中，墨量数据属于可多次改写的数据，缺墨提示信息只有在墨量耗尽时才会被改写，属于只改写一次的数据。相应地，存储模块220需要包含两个可改写数据存储区：
第一个可改写数据存储区用来存储墨量数据，并且可以如图3或图5所示的包含两个或两个以上的存储单元；
第二个可改写数据存储区用来存储缺墨提示信息，并且可以如图3所示的包含两个存储单元。
对于第一组可改写数据存储区，写控制器230和读控制器240以实施例所述的方法执行写入操作和读出操作；
对于第二个可改写数据存储区，写控制器230执行写入操作时将缺墨提示信息写入两个存储单元中没有存储信息的存储单元中，读控制器240比较两个存储单元中的值，将满足特定条件的值发送给通信模块210。
本领域普通技术人员应理解，本发明实施例中的芯片不限于上述四个组成模块，它还可以包括其它的同样能够实现通信、写入与读出以及存储的功能模块。例如用读写控制单元代替写控制器和读控制器，只要能够实现一个可改写存储区存储一种可改写数据，同一存储单元不连续两次地写入可改写数据，且通过对存储单元中的可改写数据进行比较，输出满足特定条件的可改写数据这一技术思路均属于本发明的技术思路。
本领域普通技术人员应理解，本发明实施例中的存储模块可以是一个存储元件的一部分，也可以由多个存储元件组合而成，并且各存储单元的存储空间大小既可以相同也可以不同，均能实现本发明之目的。
本领域普通技术人员应理解，本发明实施例中的写控制器、读控制器不限于以上所述的组成结构，只要借助可行的电路结构，实现写控制器控制同一存储单元不连续两次地写入可改写数据，以及读控制器控制对存储单元中的可改写数据 进行比较，输出满足特定条件的可改写数据，均可以实现本发明之目的。
本领域普通技术人员应理解，本发明实施例中的可改写数据不限于一种类型，可以是只写一次的数据、只改写一次的数据以及可多次改写的数据，均能够通过本发明所述的存储结构以及相应的写入和读出方式解决在写入错误的数据后导致正确的历史数据无法恢复的技术问题。
此外，本发明还提供了一种墨盒，其上安装有上述芯片，所述芯片存储模块中存储有表征此墨盒墨水消耗量或余量的可改写数据。
本发明实施例还提供了一种记录装置，其能够与上述墨盒配合工作，打印成像。
显然，采用本发明实施例所提供的技术方案，可以在写入可改写数据时，由写控制器控制该可改写数据写入到与最近一次写入的存储单元不相同的其它存储单元中，从而确保了芯片的存储模块中保存有最近两次的可改写数据，读控制器通过读取并比较所有存储单元中的可改写数据，并将满足喷墨打印机特定条件的可改写数据，如所有可改写数据中值最大的可改写数据，或倒数第二次写入的可改写数据，通过通信模块发送给喷墨打印机。当可改写数据为墨量数据时，芯片的存储模块中保存有最近两次的墨量数据，可以有效避免现有技术中将错误的墨量数据写入芯片，覆盖了墨量历史数据后导致无法恢复正确的墨量历史数据的技术问题。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
