上述消耗体检测装置和消耗体记录装置是分离设置在打印机中的，使得打 印机的设备复杂， 体积较大、成本较高， 且打印机与芯片间需设置多组电接触 点， 连接出现固障的几率增加， 降低了打印机工作的可靠性。 技术解决方案
本发明的第一目的是提供一种安装到打印机上用于检测和记录磁性消耗 体剩余量的装置； 本发明的第二目的是提供一种打印机上磁性消耗体剩余量的检测方法； 本发明的第三目的是提供一种打印过程中磁性消耗体剩余量信息的记录 方法。 为了实现本发明的第一目的，本发明的打印机磁性消耗体余量检测和记录 装置包括打印机中容纳磁性消耗体的盒体及其上设置的射频标签，射频标签具 有存储与磁性消耗体相关信息的存储器； 与射频标签进行通信的射频操作模 块，射频操作模块具有天线；打印机控制模块，打印机控制模块具有运算功能， 并控制所述射频操作模块读写所述射频标签。 一个优选的方案是， 射频标签包括一基板， 安装在基板上的晶圆， 晶圆内 设有存储器，晶圆的两端分别与一电容的两端连接；安装在基板上的天线线圈， 天线线圈的两端分别连接电容的两端。 线圈的电感（ )和电容（c )组成 振荡电路， 振荡电路用于接收射频模块发送过来的电磁波。 当射频标签线 圈附近有磁性物质时，磁性材料物质会加大天线线圈的相对磁导率从而增大电 感值。相应地，当磁性物质减少时，天线线圈的相对磁导率减小而减少电感值。 所以，将射频标签贴在碳粉盒或者墨盒上，碳粉盒内的磁性碳粉或者墨盒 内的磁性墨水的消耗会影响射频标签天线线圈的电感值。当碳粉或者墨水量减 少时， 天线线圈的电感值相应地减少， 从而射频标签的固有频率

) 发生变化， 需要通过打印机模块调整射频操作模块的通信功 率或者载波频率， 才能使射频操作模块与射频标签通信正常。消耗体消耗量与 射频标签的通信功率或者载波频率之间有相应地函数关系，读取射频标签的通 信功率， 可计算得出消耗体容量信息。 为了实现本发明的第二目的，本发明提供的一种打印机磁性消耗体余量检 测方法：射频操作模块与射频标签进行通信； 打印机控制模块调整射频操作模 块的通信功率逐级增大或者逐级减小，并判断射频操作模块与射频标签之间的 通信状态是否为由通信失效状态变为通信成功状态或者为由通信成功状态变 为通信失效状态， 如是， 则根据更新的射频操作模块的通信功率与磁性消耗体 容量之间的函数关系， 计算得出磁性消耗体的容量信息。 打印时， 磁性消耗体不断减少， 影响射频标签的电感值， 从而使得射频标 签的固有频率 ·^发生变化， 在射频操作模块载波频率 · ^不变的情况下，射频标 签的固有频率/偏离载波频率 /°，感应电压和效率都降低，因此导致通信异常。 在载波频率 · ^不变的条件下， 通过打印机控制模块调整射频操作模块的通信 功率， 可以使射频操作模块与射频标签恢复正常的通信， 利用恢复通信点所对 应的通信功率作为当前消耗体容量对应的测试值，根据磁性碳粉或者磁性墨水 容量与射频操作模块的通信功率之间的对应的函数关系，可得出碳粉或者墨水 剩余量信息。 进一歩的技术方案是，打印机控制模块将射频操作模块的通信功率与一个 消耗体报低阈值对应的通信功率进行比较， 判断是否一致， 如是， 则提示消耗 体容量为报低状态的信息， 如否， 则不提示。 采用以上技术方案， 增加了一个报低状态提醒的歩骤。因为打印机打印过 程中， 通常会对处理盒消耗体设置一个报低门槛， gp， 在碳粉盒中的碳粉或者 墨盒中的墨水接近耗尽状态时， 提醒用户， 碳粉或者墨水剩余量不多， 准备购 买碳粉盒或者墨盒。 此技术方案设计合理， 使用可靠。 进一歩的技术方案是，打印机控制模块将射频操作模块的通信功率与一个 消耗体耗尽阈值对应的通信功率进行比较， 判断是否一致， 如是， 则提示消耗 体容量为耗尽状态的信息， 如否， 则不提示。 使用时， 打印机耗尽状态会明确 的显示出来， 提示用户需更换碳粉盒或墨盒方可继续使用。 为了实现本发明的第二目的，本发明还提供的一种打印机磁性消耗体余量 检测方法： 打印机控制模块将射频操作模块的通信功率调整为基准功率后， 控 制射频操作模块与射频标签进行通信；打印机控制模块调整射频操作模块的载 波频率逐级增大或者逐级减小，并判断射频操作模块与射频标签之间的通信状 态是否为由通信失效状态变为通信成功状态或者为由通信成功状态变为通信 失效状态， 如是， 则根据更新的射频操作模块的载波频率与磁性消耗体容量之 间的函数关系， 计算得出磁性消耗体的容量信息。 进一歩的方案是，打印机控制模块将射频操作模块的载波频率与一个消耗 体报低阈值对应的载波频率进行比较， 判断是否一致， 如是， 则提示消耗体容 量为报低状态的信息， 如否， 则不提示。 更进一歩的方案是，打印机控制模块将射频操作模块的载波频率与一个消 耗体耗尽阈值对应的载波频率进行比较， 判断是否一致， 如是， 则提示消耗体 容量为耗尽状态的信息， 如否， 则不提示。 为了实现本发明的第三目的，本发明提供的一种打印机消耗体剩余量记录 方法是：射频操作模块与射频标签通信，射频操作模块访问射频标签并将根据 打印机磁性消耗体剩余量检测方法检测得到的消耗体剩余量信息存储到射频 标签的计量区内。
进一歩的方案是， 射频操作模块与射频标签通信， 射频操作模块访问射频 标签并将根据记录打印机打印动作估算出的消耗体消耗情况存储到射频标签 的计量区内。通过射频标签的计量区来记录通过打印机的打印动作信息估算得 到的消耗体消耗情况，将估算的消耗体消耗情况存储在射频标签的计量区。将 通过检测方法所得的检测数据和通过估算所得的估算数据都存储在射频标签 的计量区， 方便用户根据需要提取打印信息。 有益效果
由上述方案可知， 射频标签设在装有磁性消耗体的盒体上，磁性消耗体的 消耗会影响射频标签线圈的相对磁导率， 从而影响电感值， 使得射频标签的固 有频率发生变化， 射频操作模块与射频标签的通信出现异常，通过打印机控制 模块调整射频操作模块的通信功率或者载波频率，可保证射频操作模块与射频 标签进行正常通信，所以， 根据磁性消耗体容量信息与通信功率或者载波频率 之间的函数关系， 可计算得出消耗体容量信息。另外， 射频操作模块与射频标 签通信过程中，射频操作模块将调整的通信功率或者通信频率记录到射频标签 的存储器上， 即将打印过程状态记录到射频标签存储器上。该装置可同时实现 检测和记录消耗体剩余量的功能。 此外，在不改变射频操作模块的基准功率的情况下，通过调整射频操作模 块的载波频率 ， 使载波频率 接近射频标签的固有频率 ·Λ 从而射频标签 感应电压和效率才最大，射频标签通信距离达到与射频操作模块的正常通信的 距离最大。利用恢复通信点所对应的载波频率作为当前消耗体容量对应的测试 值，根据磁性碳粉或者磁性墨水容量与射频操作模块的载波频率之间的对应的 函数关系， 可得出碳粉或者墨水剩余量信息。
还有， 利用射频操作模块和射频标签之间的通信， 将通过检测方法测得的 消耗体剩余量信息存储到射频标签的一个计量区内，从而实现对打印过程信息 的记录。基于第一目的的检测和记录装置，采用基于第二目的的检测方法和基 于第三目的的检测方法， 实现了采用一种装置， 同时实现检测和记录的双重功 能， 使得打印机内检测和记录装置占用体积小， 降低成本。 附图说明

以下结合附图及各实施例对本发明作进一歩说明。 本发明的实施方式
磁性消耗体剩余量检测装置第一实施例
参见图 1， 图 1显示了根据本发明墨水剩余量检测装置的示意图。 墨盒 3 内盛装有磁性墨水 5， 在墨盒 3的盒体上粘附射频标签 4， 与射频标签 4进行 通信的射频操作模块 2安装在打印机内，且射频操作模块 2与射频标签 4保持 —定的通信距离，射频操作模块 2通过其天线发射的电磁波与射频标签 4进行 通信。 在打印机主机内设置有控制射频操作模块 2的打印机控制模块 1， 打印 机控制模块 1内设有微处理器。
磁性消耗体剩余量检测装置第二实施例
参见图 2， 图 2显示了根据本发明碳粉剩余量检测装置的示意图。 碳粉盒 6内盛装有磁性碳粉 7， 在碳粉盒 6的盒体上粘附射频标签 4， 与射频标签 4 进行通信的射频操作模块 2安装在打印机内， 且射频操作模块 2与射频标签 4 保持一定的通信距离， 射频操作模块通过其天线发射的电磁波与射频标签 4 进行通信。 在打印机主机内设置有控制射频操作模块 2的打印机控制模块 1， 打印机控制模块 1内设有微处理器。 参见图 3， 图 3是射频标签的结构示意图。 射频标签由基板、 天线、 晶圆 和晶圆内部电容组成。 基板 41上安装一个晶圆 42， 晶圆 42内设有一个内部 电容 （C ) 43， 在基板 41上还安装有天线线圈 44， 天线线圈 44的电感 （ ） 与晶圆 42的内部电容（C ) 43组成 振荡电路。 其中， 晶圆为普通技术人员 所了解的由硅半导体集成电路制成的晶片， 晶圆内设有存储器。 公知的射频通信知识：在射频操作模块固定功率的情况下，射频标签天线 L 固有频率/越接近射频操作模块的载波频率 /°， 则射频操作模块和射频标 签的可通信距离越长， 射频标签天线 LC固有频率 ί越远离射频操作模块的载 波频率 /°， 则射频操作模块和射频标签的可通信距离越短。 在固定载波频率 和固定的射频标签天线 固有频率的情况下，射频操作模块的通信功率越大， 可通信距离越长， 否则越短。 射频标签贴在碳粉盒或墨盒的盒体上，碳粉盒和墨盒内有影响线圈相对磁 导率的磁性碳粉或磁性墨水， 即磁性消耗体。在打印过程中， 随着磁性消耗体 的消耗， 射频标签的 固有频率/将偏离射频操作模块的载波频率 /°， 射频 标签的感应电压和效率都降低， 射频标签与射频操作模块之间的通信异常。通 过打印机控制模块调整射频操作模块的通信功率（可通过调整射频操作模块的 射频工作电压或其天线 Q值等实现） 或者载波频率 （可通过调整射频操作模 块天线的匹配电容实现）， 使得射频操作模块与射频标签恢复正常通信。 根据 正常通信时的射频操作模块的通信功率或者载波频率与消耗体剩余量存在的 函数关系，该函数关系可用功率与消耗体量关系和频率与消耗体量关系实验描 点法得到， 从而可以计算得出消耗体的剩余量情况。当射频操作模块与射频标 签正常通信时，射频操作模块访问射频标签的一个计量区并将打印机的打印信 息存储到该计量区内， 进而达到记录打印信息的目的。 打印机磁性消耗体剩余量检测和记录方法本例的主要原理是通过打印机 控制模块调整射频操作模块的通信功率来实现射频标签与射频操作模块之间 的正常通信， 从而对打印机消耗体剩余量进行检测， 并且将检测过程数据进行 存储。而且， 把消耗体充满的状态定位在谐振区， 即消耗体余量满时标签的固 有频率/与射频操作模块的载波频率 ·Α—致， 使用过程， 射频标签 固有频 率 ,会随着打印量的增加而偏离载波频率^ ^的谐振点，因此功率补偿级别采用 增加。 打印机磁性消耗体剩余量检测和记录方法第一实施例 参见图 4， 打印机开始打印时， 执行歩骤 S101 , 打印机控制模块调整射频 操作模块的通信功率，该功率至少要大于消耗体耗尽时射频操作模块与射频标 签能够正常通信的功率， 使射频操作模块与射频标签进行通信， 从而射频操作 模块能够读取射频标签存储器里的初始通信功率并传送到打印机控制模块，打 印机控制模块再将射频操作模块的功率更新为从射频标签读取的射频标签的 通信功率， 然后进行下述通信； 执行歩骤 S102, 打印机控制模块将射频操作模块更新的通信功率与一个 消耗体耗尽阈值对应的通信功率进行比较，判断是否一致，如是，则执行 S110, 如否， 则执行 S103 ; 打印机打印过程， 磁性消耗体不断消耗， 射频标签的固有频率发生变化， 执行歩骤 S103 , 判断射频操作模块与射频标签的通信是否失效， 如是， 执行 S104, 如否， 执行 S105 ; 歩骤 S104中， 打印机控制模块将射频操作模块通信功率增加一个级别， 然后， 返回歩骤 S103 ; 歩骤 S105中， 判断射频操作模块的通信功率是否刚增大， 如是， 则将射 频操作模块更新的通信功率存储到射频标签的存储器上， 然后执行歩骤 S106, 如否， 则直接执行歩骤 S106。 歩骤 S106中， 打印机控制模块将射频操作模块更新的通信功率与一个消 耗体报低阈值对应的通信功率进行比较，判断是否一致，如是，执行歩骤 S107 , 歩骤 S107中， 打印机控制模块输出命令， 提示消耗体消耗到报低的低门 槛容量信息， 然后， 返回歩骤 S103 ; 歩骤 S108中， 打印机控制模块比较射频操作模块更新的通信功率与消耗 体耗尽阈值对应的功率是否一致， 如是， 执行歩骤 S110, 如否， 执行 S109; 歩骤 S109中， 打印机控制模块输出命令， 将射频操作模块的通信功率数 据转化为对应的消耗体容量信息数据， 并显示消耗体容量信息， 然后， 返回歩 骤 S103 ; 歩骤 S110中， 打印机控制模块输出命令， 将射频操作模块的通信功率数 据转化为对应的消耗体耗尽容量信息数据，并显示消耗体耗尽容量信息，然后， 结束打印检测。 另外， 在本实施例的检测方法中， 射频操作模块的载波频率是固定的， 且 要保证在检测消耗体剩余量过程中，射频操作模块的通信功率始终为射频标签 存储器里的功率级别， 定义为检测级别。如果在进行检测时， 其间要穿插其他 处理程序，例如，写射频标签的存储器操作，可以将功率加大到可操作的级别， 但是操作完成后， 要恢复到检测级别的功率。 本实施例的方法， 可实现对消耗体剩余量的检测， 而且该方法中将检测所 得的消耗体容量信息进行存储， 从而能同时实现检测和记录的目的。 打印机磁性消耗体剩余量检测和记录方法第二实施例 参见图 5， 打印机开始打印时， 执行歩骤 S201 , 打印机控制模块调整射频 操作模块的通信功率，该功率至少要大于消耗体耗尽时射频操作模块与射频标 签能够正常通信的功率， 使射频操作模块与射频标签进行通信， 从而射频操作 模块能够读取射频标签存储器里的初始固有频率并传送到打印机控制模块，打 印机控制模块再将射频操作模块的载波频率更新为读取的射频标签的初始固 有频率， 且将射频操作模块的通信功率更新为基准功率， 用该基准频率来执行 下述的各种操作； 执行歩骤 S202, 打印机控制模块将射频操作模块更新的载波频率与一个 消耗体报尽阈值对应的载波频率进行比较，判断是否一致，如是，则执行 S210, 如否， 则执行 S203 ; 打印机打印过程， 磁性消耗体不断消耗， 射频标签的固有频率发生变化， 执行歩骤 S203 , 判断射频操作模块与射频标签的通信是否失效， 如是， 执行 S204 , 如否， 执行 S205 ; 歩骤 S204中，打印机控制模块将射频操作模块的载波频率增加一个级别， 然后， 返回歩骤 S203 ; 歩骤 S205中， 判断射频操作模块的载波频率是否刚增大， 如是， 则将射 频操作模块更新的载波频率存储到射频标签的存储器上， 然后执行歩骤 S206 , 如否， 则直接执行歩骤 S206。 歩骤 S206中， 打印机控制模块将射频操作模块更新的载波频率与一个消 耗体报低阈值对应的载波频率进行比较，判断是否一致，如是，执行歩骤 S207 , 如否， 执行歩骤 S208; 歩骤 S207中， 打印机控制模块输出命令， 提示消耗体消耗到报低的低门 槛容量信息， 然后， 返回歩骤 S203 ; 歩骤 S208中， 打印机控制模块将射频操作模块更新的载波频率与一个消 耗体耗尽阈值对应的载波频率进行比较，判断是否一致，如是，执行歩骤 S210 , 如否， 执行 S209; 歩骤 S209中， 打印机控制模块输出命令， 将射频操作模块的载波频率数 据转化为对应的消耗体容量信息数据， 并显示消耗体容量信息， 然后， 返回歩 骤 S203 ; 歩骤 S210中， 打印机控制模块输出命令， 将射频操作模块的载波频率数 据转化为对应的消耗体耗尽容量信息数据，并显示消耗体耗尽容量信息，然后， 结束打印检测。 另外， 在本实施例的检测方法中， 也要保证在检测消耗体剩余量过程中， 射频操作模块的通信功率始终为基准功率。如果进行检测时， 其间要穿插其他 处理程序，例如，写射频标签的存储器操作，可以将功率加大到可操作的级别， 但是操作完成后， 要恢复到基准功率。 本实施例的方法， 可实现对消耗体剩余量的检测， 而且该方法中将检测所 得的消耗体容量进行存储， 从而同时实现检测和记录的目的。 对于第一实施例和第二实施例，还可将磁性碳粉或者磁性墨水的初始打印 信息， 如生产厂家、 生产日期、 打印量等， 存储在射频标签中， 使得记录的打 印信息完整。 第一实施例和第二实施例中的记录是通过存储检测所得数据，即实测所得 数据， 对打印过程信息进行记录。 打印机磁性消耗体剩余量记录方法实施例 参见图 6， 打印机开始打印时， 执行歩骤 S301 , 射频操作模块读取射频标 签存储器的计量区中的消耗体容量数据，该计量区中的容量数据具有断电不丢 失的特点； 然后， 执行歩骤 S302 , 打印机控制模块将射频标签所读取的消耗体容量 数据与一个消耗体耗尽数据进行比较， 判断是否一致， 如是， 则结束， 如否， 则执行歩骤 S303 ; 打印过程中， 消耗体不断消耗， 歩骤 S303中， 射频标签计量区通过记录 打印动作的消耗体消耗情况，即根据消耗体消耗数量和消耗体总量估算出消耗 体剩余量后记录到射频标签计量区的容量区， 然后， 执行歩骤 S304; 歩骤 S304中， 打印机控制模块将通过磁性消耗体剩余量检测方法测得的 消耗体容量信息与一个消耗体报低阈值对应的数据进行比较， 判断是否一致， 如是， 则将消耗体剩余容量为报低的状态存储到射频标签计量区的容量区， 然 后， 执行歩骤 S303 , 如否， 执行歩骤 S305 ; 歩骤 S305中， 打印机控制模块将通过磁性消耗体剩余量检测方法测得的 消耗体容量信息与一个消耗体耗尽阈值对应的数据进行比较， 判断是否一致， 如是， 则将消耗体剩余量耗尽信息存储到射频标签计量区的容量区， 结束， 如 否， 执行歩骤 S303。 通过射频标签和射频操作模块的通信，将通过记录打印机打印动作得到的 打印信息和通过实际检测方法得到的消耗体报低及耗尽状态信息存储在射频 标签的计量区内， 实现了对打印信息的记录。 本实施例的记录方法，其与第一实施例和第二实施例中的记录方法的区别 是，在报低前是靠打印机控制模块对打印量的运算及射频标签的存储来达到消 耗体的计量和存储， 即打印机的估算及芯片的存储， 没有实测， 而报低和报尽 是通过检测方法来实现的， 即报低和报尽是通过实测来实现的。 本实施例中， 将估算值和实测值一起存储在射频标签中， 方便用户提取需要的信息。 本发明中所提到的 "报低"， 指的是， 在打印过程中， 设定一个报低的数 值， 当碳粉或者墨水的剩余量达到该数值时， 打印机会显示报低状态， 即提醒 用户， 碳粉或者墨水将要用尽， 做好购买碳粉盒或墨盒的准备。 本发明所提到的记录打印动作得到的打印信息，是指通过打印机控制模块 对打印量的运算及对射频标签的存储来达到消耗体的计量和存储，即打印机的 估算及芯片的存储。通过驱动程序根据打印页数， 页面墨粉覆盖率等信息估算 出消耗体消耗数量、 并根据消耗体总量估算出消耗体剩余量。 本发明采用射频装置，对打印机中的磁性碳粉或者磁性墨水进行检测， 并 利用射频标签内的存储功能， 实现记录， 使得同一种装置即可实现检测和记录 两种功能， 既节省了打印机中检测和记录装置所占用的体积， 又降低了成本， 本发明的装置和方法均使用可靠、 操作方便。
当然， 上述实施例仅是本发明较佳的实施方案， 实际应用时还可以有更多 的变化， 例如， 本发明的消耗体剩余量检测和记录方法的两个实施例中， 都是 把消耗体充满的状态定位在谐振区， 即消耗体余量满时标签的固有频率 ·^与射 频操作模块的载波频率 一致， 使用过程， 射频标签 固有频率/会随着打 印量的增加而偏离载波频率 · ^的谐振点， 因此补偿 （功率或频率） 级别采用 增加， 其实， 也可以将消耗体耗尽设定在谐振区， 则随着打印量增加， 射频标 签 固有频率/会逼近载波频率 /°的谐振点， 因此通信逐渐增强， 通信由不 正常转为正常， 可将补偿（功率或频率）级别相应地设为减少， 这些改变同样 可以实现本发明的目的。
最后需要强调的是， 以上举例仅仅是对本发明的解释而不是限制， 本发明 的保护范围以权利要求的内容为准。作为本领域的普通工程技术人员， 任何基 于本发明的发明创造精神而作出的等效技术变换都在本发明的保护范围之内。 工业适用性
