Description

数据处理方法及数据处理装置 技术领域
本发明涉及耗材数据处理技术领域，具体涉及一种数据处理装置及使用该装置进行识别、烧录等数据处理的方法。
背景技术
打印机、复印件及传真机等成像设备对碳粉或者墨水等耗材的使用通常需借助于芯片来控制。目前做通用芯片的公司通常会利用对OEM原装芯片进行复位之后重新使用，或者制作与原装芯片相同或相似功能的替换芯片代替原装芯片使用(该替换芯片在经过复位之后能重复使用)，从而可以达到降低芯片浪费的效果。另外不同类型的成像设备所使用的芯片类型通常是不相同的，若芯片类型与成像设备不匹配时会导致成像设备无法使用耗材，从而导致打印机不能正常工作，因此安装芯片之前需要对芯片的类型进行识别。
但是目前不论对芯片进行识别还是复位通常需要相应的设备进行处理。现有的设备包括设备主机及识别头，识别头与设备主机通过连接线连接，识别头上设置有识别探针。现有技术中针对不同类型的芯片分别对应设置一个识别头，因此每个设备主机都要配备很多个识别头，从而导致使用的时候非常麻烦。例如，需要从众多的识别头中挑选适当的识别头是件不容易的事情，或者当使用者不了解芯片的类型时，否则很容易出现将用于B类型芯片的识别头去操作A类型的 芯片，降低工作效率。

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：
方法实施例
参照图1、图2与图3，本实施例提供一种数据处理方法，包括如下步骤：
步骤S1，数据处理装置100发送当协议类型对应的识别数据至芯片。所述数据处理装置可以包括主机1及识别头2，所述识别头2可用于与芯片200接触，当识别头2与芯片200接触之后，可通过主机1向相应的芯片200发送所述识别数据。所述识别数据可以为芯片200的地址信息，或者根据协议类型所设定的标识，以下各实施例分 别以地址信息为例进行说明。所述识别数据的协议类型包括多种，不同品牌或者相同品牌的不同系列芯片所对应的识别数据的协议类型可能不同。例如京瓷O系列激光打印机芯片与理光P系列激光打印机芯片的识协议类型就不一致，并且芯片200与数据识别装置100通信时采用的协议或者方式也可能不一致。各个协议类型的识别数据分别包括K组识别数据，其中K取值范围可为1-256的自然数。本实施例中所述主机1可存储有多个类型的协议类型。当前协议类型可包括多个或多组识别数据。每次可发送当前协议类型中的一个或者一组识别数据至芯片。
芯片200在接收到识别数据之后，对识别数据进行分析，判断所述识别信息是否合法，并将判断的结果通过识别头2发送至所述主机1。例如该识别数据为地址信息0×03，芯片200在接收到该识别数据之后，将该识别数据与芯片200的地址信息进行比对，若芯片200的地址信息也为0×03则说明识别数据是合法的，否则不合法。不同类型芯片与主机通信采用的协议或者方式可能不同，若采用相同协议或者方式的可能识别信息(即：地址信息)不同。
步骤S2，数据处理装置接收所述芯片200在接收到所述识别数据之后返回的判断识别数据是否合法的判断结果。所述芯片200在接收到所述识别数据之后，对识别数据进行判断是否合法，或者说，所述识别数据与该芯片200是否匹配，若是，则返回识别数据是合法的判断结果，否则返回识别数据不合法的判断结果，并将该判断结果发送通过识别头2发送至主机1内并执行步骤S3。例如芯片200实际 是以第一类型协议与数据处理装置通信的，当数据处理装置向芯片200发送第一识别数据之后，芯片200在接收到该第一识别数据时判断芯片200内的识别数据是否与第一识别数据一致，若是，则返回合法的判断结果，否则返回不合法的判断结果。
步骤S3，数据处理装置100对判断结果的合法性进行分析，并根据分析结果作出相应处理。具体的，本实施例的步骤S3中可通过数据处理装置100的主机1对判断结果进行分析，若分析出所述判断结果为合法的，则说明数据处理装置100与芯片200验证通过，因此两者可以通行通信。若所述判断结果为识别数据是不合法的；主机1执行切当前协议类型的其他换识别数据或者切换当前协议类型等操作，例如可则执行步骤S4。
若步骤S3中分析出所述判断结果为合法，从而说明可以通过数据处理装置100对芯片200进行复位、数据烧录或者诊断等操作，操作的指令及数据等内容通过识别头2在芯片200与主机1之间传输。此时还可以包括如下步骤S6：
数据处理装置100根据相应的协议类型发送待处理的数据给芯片200。作为优选方案，所述数据处理的指令包括读取芯片200数据的指令或者向芯片200写入数据的指令等。所述协议类型可以包括IIC通信协议、串口通信协议或者ONE WIRE通信协议等。所述待处理的数据包括识别芯片的数据或者烧录芯片的数据或者诊断芯片的数据等。
步骤S4，判断是否切换当前协议类型。若不需切换当前协议类 型时，则可以采用类似步骤S1继续发送当前协议类型中的其他识别数据至芯片200，继续对芯片200与数据处理装置100进行验证。若需要切换当前数据的类型时，则可执行步骤S5。
所述判断是否切换当前协议类型的过程可包括如下步骤，即步骤S4可以包括如下子步骤：
步骤S41，当数据处理装置100接收所述芯片200在接收到所述识别数据之后返回的判断识别数据是不合法时，判断当协议类型对应的识别数据是否发送完毕。例如当协议类型对应的识别数据包括256个，当将所述256个识别数据全部发送至芯片200识别之后，芯片200均返回识别数据为不合法的判断结果，因此说明当协议类型对应的识别数据发送完毕，并执行步骤42；否则，当协议类型对应的识别数据没有发送完毕，则执行步骤43。
步骤S42，若步骤S41判断结果为是时，则说明需要切换当前协议类型，则执行步骤S5。例如在切换之前协议类型为A类打印机芯片对应的协议类型M，切换之所述协议类型为B类打印机芯片类对应的协议类型N。切换前A类打印机芯片对应的识别数据的协议类型M为当前协议类型。切换后是将B类打印机芯片对应的协议类型N作为当前识协议类型。
步骤S43，若步骤S41判断结果为否时，则说明不需要切换当前协议类型。此时仍可采用步骤S1的方式将当前协议类型中的其他识别数据发送至芯片200进行验证，例如当协议类型对应的识别数据0×03发送至芯片200之后，芯片200返回的判断结果为该识别数据 为不合法识别数据，并且当识别数据0×03之后还存在识别数据0×04、识别数据0×05、……识别数据0×0FF等没有发送至芯片200进行识别时，此时还可以将剩余的识别数据0×04、识别数据0×05、……识别数据0×FF等分别发送至芯片200进行识别，直至存在合法的识别数据，否则就会执行步骤S5进行协议类型进行切换。
步骤S5，若所述步骤4中的判断结果为是时，将下一个协议类型作为当前协议类型，并将切换后的当协议类型对应的识别数据发送至芯片200，直至所述数据处理装置100接收到所述芯片200在接收到所述识别数据或者切换后的识别数据之后返回的判断的结果为合法的。切换前的协议类型将可能会被标识为上一个协议类型。例如，切换之前的当前协议类型为M，下一个协议类型为N，在切换之后，所述当前协议类型则变成了N，而M则成了上一个协议类型。将切换当前类型后的识别数据发送至芯片的过程可采用步骤S1。
综上所述，本实施例中数据处理装置的通过切当前协议类型及识别数据来使得识别头可以用于不同类型的芯片，因此不用针对不同类型的芯片设置不同的识别头，达到识别头可以通用于不同类型打印机的芯片，进而提高数据处理装置使用的效率。
作为另一较佳实施例，步骤S4及步骤S5还可以设置于步骤S1之前，如图2所示。
装置实施例
参照图3-图5，本发明的实施例一种数据处理装置100，包括主机1及识别头2。所述主机1可包括壳体11及安装于壳体内的电路 板(图中未示出)。所述识别头2通过连接线3与主机1连接。所述识别头2上安装有识别探针21。所述识别探针21用于与芯片200接触，在芯片200与主机1通信过程中该识别探针21用于传输数据。每个识别头2上可安装多个识别探针21，例如每个识别头2上可安装有两个识别探针21、四个识别探针21或者五个识别探针21等。所述识别探针21可为金属探针，例如铜或者银或者合金等。各识别头2上的识别探针21可用于不同的功能，以四个识别探针21的识别头为例，该四个识别探针21可分别用于作为数据线、电源线、时钟线及地线，且该识别探针21中的部分或者全部的功能可以切换。切换识别探针21功能的过程可在上述方法实施例中切换当前协议类型的过程中实现，例如在切换协议类型之后，可向本来作为数据线的识别探针发送时钟，向本来作为时钟线的发送数据，使得数据线与时钟线的功能发生切换。
参照图4，所述主机1还可包括第一数据处理单元12、第二数据处理单元13及切换单元14。所述识别探针21与第一数据处理单元12连接。所述第一数据处理单元12与第二数据处理单元13连接。所述切换单元14与第一数据处理单元12及第二数据处理单元13均连接。所述第一数据处理单元12、第二数据处理单元13及切换单元14可分别设置于主机1的电路板上。数据处理装置100在于芯片200验证和/或数据处理的过程可采用以上方法实施例中的任何一种方法进行。
所述第一数据处理单元12用于向芯片100发送识别数据及接收 所述芯片200在接收到所述识别数据之后返回的判断识别数据是否合法的判断结果，并将判断结果发送至第二数据处理单元13。参照图3，所述第一数据处理单元12包括若干第一引脚121，各第一引脚分别121与一个所述识别探针21连接。所述第一引脚121还与所述第二数据处理单元13连接。作为优选方案，所述第一数据处理单元12还可包括保险丝122及滤波器123。所述保险丝122与所述第一引脚121均连接，所述滤波器123与所述保险丝122串联。所述保险丝122用于保护所述识别头2及主机1。所述滤波器123可用于过滤掉第一数据处理单元12与第二数据处理单元13在数据传输过程中的杂波，从而提高数据处理的效率。所述滤波器123可包括两个并联的电容，其中一个电容用于过滤低频波，另一个可用于过滤高频波。
参照图5，所述第二数据处理单元13可用于判断是否切换识别数据的协议类型。所述切换单元14可用于根据所述第二数据处理单元13判断结果为切换识别数据的协议类型时，对部分或者全部识别探针21的功能进行切换，实现识别头3通用于不同类型的芯片。所述第二数据处理单元13可以包括若干第二引脚131，各第二引脚131分别与第一引脚121连接。在第二引脚131分别与第一引脚121连之后，第一数据处理单元12可与第二数据处理单元13进行数据传输。
作为优选方案，所述第二数据处理单元13可为单片机，例如可为STM32系列的单片机，第二数据处理单元13可在接收到判断结果后，对判断结果进行分析，当所述判断结果为识别数据合法，则根据相应的指令对芯片200进行数据处理，当所述判断结果为识别数据合 法不合法，则判断是否切换当前协议类型。
作为优选方案，所述第二数据处理单元13还可以包括用于与切换单元14连接的第三引脚132。
所述切换单元14包括继电器电路141及电源切换电路142，所述继电器电路141与电源切换电路142连接。所述继电器电路141与所述第三引脚132连接，可通过继电器电路141中的继电器1411切换不同的引脚实现电压的切换，从而使得相应识别探针21的功能发生变化。所述继电器1411与所述电源切换电路连接。所述电源切换电路142可通过控制用于作为电源线的识别探针21的功能发生变化。该电源切换电路142还可与所述第一数据处理单元连接，具体地，电源切换电路142与保险丝122及滤波器123均连接。当然所述继电器电路141及电源切换电路142的切换操作可不同时进行，从而达到改变识别探针21功能切换的操作，进而使得识别头2可以通用于不同类型的芯片。
所述电源切换电路142可以包括三极管Q4及电阻(R42、R43)；所述三极管Q4可与继电器1411连接。所述电阻R42与电阻R43连接，电阻R43接地。所述三极管Q4的栅极G与电阻R42连接，漏极D与保险丝122连接；源极S与继电器1411连接。
参照图6，作为另一较佳方案，为了更好的达到识别头通用的目的，所述继电器电路141可以包括第一继电器电路141a和第二继电器电路141b。所述第一继电器电路141a包括第一继电器1411a、三极管Q5、电阻(R44、R54)及二极管D6。所述第二继电器电路141b 包括第二继电器1411b、三极管Q24、电阻(R30、R108)及二极管D16。

启动数据处理装置，可通过数据处理装置执行数据烧录功能。将识别头上的识别探针与芯片A(即：A类打印机芯片)上可用于数据烧录的端子接触，然后数据处理装置的主机可通过识别头的识别探针向芯片A发送当前协议类型M中的一个识别数据至芯片A，芯片A接收到该识别数据之后对识别数据进行判断是否合法，若合法则将该 判断结果通过识别探针发送至主机，主机在接收到识别数据为合法的结果之后，则说明需要烧录的芯片A类型与数据处理装置中待烧录的当前协议类型M是匹配的，因此可通过数据处理装置可正常向芯片A进行数据烧录。若更好成芯片B(即：B类打印机芯片)，则当前的协议类型M中所有的识别数据均有可能被芯片B识别为不合法的识别数据，此时芯片B还是会将该判断结果通过识别探针发送至主机，将当前协议类型M中所有的识别数据均发送完毕之后，芯片仍然不能正常与主机通信，则发送下一个协议类型N的识别数据至芯片B，为满足切换后的协议类型N，所述识别探针的部分或全部的功能则需要发生变化，当芯片B收到某个识别数据为合法的时，则说明芯片B为可以与协议类型N匹配的芯片，此时的切换过程通过第二数据处理单元及切换单元实现，无需切换识别头，从该例子中可以得出同一个识别头可用于芯片A和芯片B。当然本发明的识别头并非仅适用于与两种类型的芯片，其可以适用于至少两个类型的芯片，本实施例中不予赘述。
综上所述，本实施例所述的数据处理装置通过第二数据处理单元发送所述识别数据并通过第一数据处理单元发送至芯片，并接收芯片返回的数据，从而实现数据处理装置与芯片通信；还通过切换单元接收到第二数据处理单元发送的切换指令实现切换识别头上识别探针的功能，使得识别头能通用于不同类型芯片的效果进，而提高数据处理装置的使用效率。
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。
