具体实 Jfe方式
以下将结合附图及实施例来详细说明本发明的实施方式， 借此对本发 明如何应用技术手段来解决技术问题， 并达成技术效果的实现过程能充分 理解并据以实施。 需要说明的是， 只要不构成冲突， 本发明中的各个实施 例以及各实施例中的各个特征可以相互结合， 所形成的技术方案均在本发 明的保护范围之内。
图 3A为本发明一实施例中成像盒芯片的组成示意图， 如图 3A所示， 本发明一种实施例的成像盒芯片包括信息存储单元 31、 延迟告警单元 32和 模拟传感器 33， 其中， 信息存储单元 31 中存储成像盒中的记录材料剩余 量， 用于在记录材料剩余量低于预设阈值时向延迟告警单元 32发送告警指 示信号。 具体的， 可以根据由与所述成像盒连接的成像装置成像装置根据成 像盒中记录材料总容量、 以及成像过程中每次成像时记录材料的消耗量计算 获得后写入到成像盒芯片的墨量数据获取所述记录材料剩余量。 简言之， 可 根据与所述成像盒连接的成像装置写入到成像盒芯片的墨量数据获取所述 记录材料剩余量。 延迟告警单元 32用于延长告警指示信号的有效时间， 告 警指示信号的有效时间大于成像装置对信息存储单元 31和模拟传感器 33的 供电间隔时间； 模拟传感器 33用于在检测到延迟告警单元 32上维持有告警 指示信号时， 发出告警信息， 或在未检测到延迟告警单元 32上维持有告警 指示信号时， 发出记录材料充盈信息。 更具体地， 模拟传感器 33 可通过模 拟用于监测成像盒墨量的实际传感器的输出来发出告警信息和 /或记录材料 充盈信息， 以适配所述成像装置进―行缺墨预警的固有检测需求。 换而言之， 传统的成像盒通过用于监测成像盒墨量的实际传感器的输出来适配所述成 像装置进行缺墨预警的固有检测需求， 而在本发明中， 取而代之地由模拟传 感器 33来模拟用于监测成像盒墨量的实际传感器的输出以发出告警信息和 / 或记录材料充盈信息， 进而适配所述成像装置进行缺墨预警的固有检测需 求。 从而可以在即便不设置用于监测成像盒墨量的实际传感器也可以满足成 像设备的适配需求。
其中的预设阈值可以根据成像装置的不同配置， 或模拟传感器特性的 不同特性确定， 例如可以设为 20%或其他数值， 即在成像盒中记录材料剩 余量低于记录材料总容量的 20%时， 信息存储单元 31发送告警指示信号。
本实施例中， 延迟告警单元 32 的作用为延长告警指示信号的有效时 间， 且告警指示信号的有效时间大于成像装置对信息存储单元 31 和模拟传 感器 33 的供电间隔时间， 避免了成像装置对成像盒芯片的信息存储单元和 模拟传感器的供电时间不同步所带来信号传递问题。
在上述图 3A所述实施例的基础上， 图 4为本发明另一实施例中成像盒 芯片的组成示意图， 如图 4所示， 其中延迟告警单元 32具体为一电容 42, 电容 42 的第一端 421 直接连接在信息存储单元与模拟传感器之间的电路 上， 电容 42的第二端 422直接接地， 另外也可以^ _第一端 421与电路之间 串联上电阻等元件， 二者间接连接； 或者是第二端 422串联上一个电阻等元 件后接地， 以实现间接接地。
在上述图 3A所述实施例的基础上， 延迟告警单元 32具体还可为串联在 信息存储单元 31与模拟传感器 33之间的电路上的电感。
在上述图 3A所述实施例的基础上， 图 5为本发明又一实施例中成像盒 芯片的组成示意图， 如图 5所示， 其中延迟告警单元 32为设置在信息存储 单元 31与模拟传感器 33之间的电路上的电平触发器 52, 并由一供电电池供 电。
在上述实施例中， 延迟告警单元 32可独立设置、 与信息存储单元集成 设置或与模拟传感器集成设置， 图 6为本发明再一实施例中成像盒芯片的组 成示意图， 如图 6所示， 其中延迟告警单元 32为一电容 62, 且电容 62与信 息存储单元 31集成设置。
以上实施例所提供的成像盒芯片均可解决信息存储单元 31 和模拟传感 器 33供电不同步造成的信号传递问题， 进而实现告警信息的准确提供。
另一可选的方案是， 延迟告警单元为一非易失性存储器， 模拟传感器 包括低压线性稳压器以及周期信号发生器， 其中低压线性稳压器从成像装 置处接收高压脉冲， 并将高压脉冲转换成低压直流电压 VDD提供给延迟告 警单元以及周期信号发生器作为供电电源， 延迟告警单元中的记录材料余 量指示信号发送到周期信号发生器， 周期信号发生器根据记录材料余量指 示信号发出记录材料充盈的信息或者发出记录材料缺乏的告警的信息。 如图 9所示， 延迟告警单元 82为一次性可编程的一位 PROM, 由电阻 R1,R2,二极管 D1，熔丝 U1组成， 熔丝 U1优选为较低熔点的熔丝。 选择合适 的 R1和 R2参数， 当记录材料剩余量大于预设阈值 20%, 信息存储单元 3! 通过管脚 DIN向延迟告警单元 82输出低电平， U1导通， 当模拟传感器 83 的低压线性稳压器 831将打印机发送的高压膝冲转换成低压直流信号 VDD 输出后， 管脚 DOUT输出信号 0到模拟传感器的周期信号发生器 832。 模拟 传感器的周期信号发生器接收到信号 0, 发出记录材料充盈的信息， 具体可 以为一特定频率的周期信号， 例如为 33 HZ; 当记录材料剩余量低于预设 阈值， 信息存储单元通过管脚 DIN 向延迟告警单元输出高电平， 通过熔丝 U1的电流大于熔断电流， 持续一段时间后， 熔丝 Ui熔断， 当模拟传感器的 低压线性稳压器将打印机发送的高压脉冲转换成低压直流信号 VDD 输出 后， 由于熔丝 U1熔断， 管脚 DOUT输出电压接近 VDD, 为高电平， 周期信 号发生器接收到数据 1， 发出记录材料缺乏的告警的信息， 具体可以为一特 定频率的周期信号， 例如为 100 ΗΖ„
图 10为本发明的另一实施例， 在该实施例中， 延迟告警单元具体为可 进行多次编程的多位非易性存储器 92, 可选择 EEPROM, FRAM, FLASH 等。 模拟传感器 93 包括低压线性稳压器 931、 非易失性存储器接口控制器 932、 周期信号发生器 933 , 其中低压线性稳压器 931将打印机提供的高压脉 沖转换成低压直流信号提^ ^给非易性存储器接口控制器 932以及周期信号发 生器 933作为工作电源， 非易失性存储器接口控制器 932连接非易失性存储 器 92， 向非易失性存储器提供工作电源， 从非易失性存储器读取记录材料 余量指示信号并传送到周期信号发生器。
非易失性存储器 92 管^ VDD1,GND1,DIN 分别连接到信息存储单元 91， 非易失性存储器 92管脚 VDD2,GND2， DOUT分别连接到模拟传感器的 非易性存储器接口控制器 932。 当成像装置对信息存储单元上电， 则信息存 储单元给非易失性存储器上电， 成像装置向信息存储单元写入记录材料剩 余量， 信息存储单元比较记录材料剩余量与预设阈值， 当记录材料剩余量 低于预设阈值 20%, 信息存储单元向非易性存储器写入记录材料余量指示 信号数据 1， 当记录材料剩余量等于或高于预设阈值 20%, 信息存储单元向 非易性存储写入记录材料余量指示信号数据 0。 成像装置对信息存储单元掉 电， 信息存储单元对非失性存储器掉电。 信息存储单元写入非易失性存储 器的数据依然保留在非易性存储器。 成像装置对模拟传感器供电， 非易性 存储器接口控制器接收到低压线性稳压器发送的低压直流信号 VDD后， 对 非易失性存储器上电以及从非易性存储器读取数据， 并将读取的数据传送 到周期信号发生器， 周期信号发生器接收到记录材料余量指示信号数据 0, 发出记录材料充盈的信息， 具体可以为一特定频率的周期信号， 例如为 33KHZ, 周期信号发生器接收到记录材料余量指示信号数据 1 , 发出记录材 料缺乏的告警的信息， 具体可以为一特定频率的周期信号， 例如为 100ΚΙίΖ。
如图 11所示， 延迟告警单元集成在信息存储单元中。 信息存储单元 101 包括数据存储区、 非易性存储器 102, 其中非易失性存储器作为延迟告警单 元， 与模拟传感器中的非易失性存储器接口控制器连接。 信息存储单元 101 的数据存储区存储成像盒的各种相关数据， 其中包括成像盒的记录材料的 记录材料余量数据， 数据存储区将记录材料剩余量与预设阈值 20%进行比 较， 根据记录材料剩余量大于预设阔值 20%或者小于预设阈值 20%, 向非易 性存储器输出不同的记录材料余量指示信号。 随后当成像装置对信息存到 单元掉电， 对模拟传感器上电， 则低压线性稳压器将成像装置发送的高压 脉冲转换成低压直流信号 VDD后， 非易失性存储器接口控制器对非易失性 存储器！02上电， 读取记录材料余量指示信号并输出到周期信号发生器， 周 期信号发生器根据记录材料余量指示信号产生不同的周期信号 , 该周期信 号能匹配信息存储单元中的记录材料剩余量的数据。
另一可选的方案是， 也可以将非易失性存储器集成在模拟传感器中。 进一步的优选方案， 可设置模拟传感器输出多于两种的不同频率特性 的周期信号。 此时在记录材料余量低于预设阈值 20%， 信息存储单元给多 次可编程存储器上电并向所述多次可编程存储器发送告警指示信号； 在记 录材料余量等于或高于预设阈值 20%, 信息存储单元给多次可编程存储器 上电并向所述多次可编程存储器发送记录材料余量设定量级的墨量信号。 设定量级为： 记录材料佘量大于预设阈值 20%情况下， 可具体表示记录材 料余量从余量 100%至余量 20%的其中一个量级。 例如, 可设置设定量级分 别为余量 100%, 余量 80%, 余量 60%, 余量 40%。 相应的， 根据量级的个 数需要设置延迟告警单元数据所包含的位数。 例如， 当设定量级有 4个， 则 记录材料余量指示信号需要具有 22位数据， 可令模拟传感器可输出 4种不同 频率特性的周期信号； 例如， 当设定量级.有 8个， 则当记录材料余量指示信 号需要具有 23位数据， 可令模拟传感器可输出 8种不同频率特性的周期信 号， 以此类推。 可根据实际情况， 预先设定不同记录材料余量设定量级所 对应的模拟传感器输出频率以及对应的信息存储单元写入非易失性存储器 的数据。 该优选方案充分利用非易失性存储器的可存储， 写入以及输出多 位数据的特点， 设计令模拟传感器输出多于两种的频率， 这样， 模拟传感 器的输出波形更接近于可真实测量记录材料余量的传感器的输出波形。
作为延迟告警单元的非易失性存储单元可以选择存储器为电可擦可编 程只读存储器 (EEPROM)、 闪存 (flash memory), —次性可编程存储器或铁电 存储器 (FRAM)等， 具有可改写、 掉电后数据不丟失特性即可。 非易失性存 储单元可独立设置、 与信息存储单元集成设置或与模拟传感器集成设置。 由于该非易失性存储单元只需要存储墨量指示信号， 可选择存储容量小， 功耗低的非易失性存储器。
非易失性存储器与模拟传感器以及信息存储单元的通信协议可以是单 总线协议， IIC协议等等， 可根据选定的通信协议选择具体的非易性存储器 的类型以及型号， 并根据上述两者进行非易性存储器与信息存储单元和模 拟传感器之间的线 连接。
上述各实施例中模拟传感器发出告警信息具体可为模拟传感器输出一 表征记录材料不足的信号， 该信号具有一特定频率， 例如 lOOKhz; 成像装 置在检测到该特定频率的信号后进行报警， 例如在显示器上显示 "叹 号，， 、 "EF, 预警状态标识" 等， 或者是通过闪灯报警 这祥即可实现由 信息存储单元 31和模拟传感器 33同时通知成像装置成像盒记录材料即将耗 尽， 使成像装置在适当的时候停止工作， 保护成像作业机构。
需要说明的是， 成像盒芯片的接口控制器可设置于模拟传感器中或单 独设置。
非易失性存储器可与信息存储单元集成设置。
此外， 延迟告警单元可独立设置、 或者与信息存储单元集成设置， 或 本发明还提供了一种成像盒， 包括上述的成像盒芯片。
本发明还提供一种记录材料剩余量的告警处理方法， 虽然已经分别在 上述各实施例中说明了告警处理方法， 下述进一步结合图 7示出的本发明一 实施例中记录材料剩余量的告警处理方法的流程示意图来进行说明。 如图 7 所示， 本实施例的记录材料剩余量的告警处理方法包括:
步骤 701、 信息存储单元在记录材料剩余量低于预设阈值时向延迟告警 单元发送告警指示信号；
其中信息存储单元中存储有成像盒中的记录材料剩余量， 具体的， 该 记录材料剩佘量可以为根据成像盒中记录材料总容量， 以及成像过程中每 次成像时记录材料的消耗量计算获得。
其中的预设阈值可以根据成像装置的不同配置， 或模拟传感器特性的 不同特性确定， 例如可以设为 20%或其他数值。
步骤 702、 模拟传感器检测延迟告警单元上是否维持有告警指示信号， 若是执行步骤 703 , 否则执行步骤 704;
其中延迟告警单元用于延长告警指示信号的有效时间， 告警指示信号 的有效时间大于成像装置对信息存储单元和模拟传感器的供电间隔时间。
步驟 703、 在检测到延迟告警单元上维持有告警指示信号时， 模拟传感 器发出告警信息， 返回步骤 702继续检测；
其中模拟传感器发出告警信息具体可为模拟传感器输出一表征记录材 料不足的信号， 该信号具有一特定频率， 例如 lOOKhz; 成像装置在检测到 该特定频率的信号后进行报警， 例如在显示器上显示 "叹号" 、 "EF , 预 警状态标识" ， 或者是通过闪灯报警等方式。
步骤 704、 在未^ k测到延迟告警单元上维持有告警指示信号时， 模拟传 感器发出记录材料充盈信息， 返回步骤 702继续检测；
其中模拟传感器发出记录材料充盈信息具体可为模拟传感器输出另一 特定频率的信号， 例如 33Κ1ιζ的信号。
本实施例中， 信息存储单元在记录材料剩余量低于预设阈值时向延迟告 警单元发送告警指示信号， 而延迟告警单元能够为延长告警指示信号的有效 时间， 使得告警指示信号的有效时间大于成像装置对信息存储单元和模拟传 感器的供电间隔时间， 因而在成像装置对模拟传感器供电时， 模拟传感器扔 能够^ ^测到延迟告警单元上维持的告警指示信号， 从而能够有效避免成像装 置对成像盒芯片的信息存储单元和模拟传感器的供电时间不同步所带来的问 题。

其它实施例
在上述各实施例中， 成像芯片还可包括一墨量状态标识设置模块 34(参 考图 3B)。墨量状态标识设置模块 34可用于根据记录材料剩余量和预设阈值 的比较结果设置其墨量状态标识。 更具体例地， 墨量状态标识设置模块 34 在所述记录材料剩余量小于上述预设阈值， 将所述成像盒的墨量状态标识 设置为第一标识。 该第一标识用于表示成像盒当前处于记录材料不充盈状 态。 进一步的， 所述墨量状态标识设置模块 34还可用于在记录材料剩余量 等于或高于预设阈值时， 将所述成像盒的墨量状态标识设置为第二标识； 所述第二标识用于表示成像盒当前处于记录材料充盈状态。 第一标识和第 二标识的具体表现形式不受限制， 如可采用任意两个不同的数值， 分别表 示上述第一标识和第二标识。
下面参考图 13 来详细说明打印机的根据墨盒的模拟传感器的输出信号 通过墨量状态标识设置模块 34设置成像盒的墨量状态标识， 再根据对成像 盒的墨量状态标识的检测结果， 进行成像盒墨量的缺墨预警的实例。
步驟 131 : 打印机开始打印数据。
步驟 132: 打印机在打印过程中， 根据打印数椐估算墨量数据， 并将估 算得到的墨量数椐写入到成像盒芯片； 执行步骤 133和步骤 135。
步驟 133: 成像盒芯片的根据墨量数据获^!成像盒的记录材料剩余量， 判断成像盒的记录材料剩余量是否小于预设阈值； 如果成像盒的记录材料 剩余量小于预设阈值, 則执行步驟 134; 否则， 执行步骤 132。
打印机写入的墨量数据可为： 打印机已打印数据消耗的墨量。 成像盒 芯片根据该墨量数据， 可计算成像盒当前的记录材料剩余量， 并将成像盒 的记录材料剩余量与预设阈值进行比较。 所述预设阈值可为成像盒总墨量 的 20%。 如果比较结果为成像盒的记录材料剩余量小于成像盒总墨量的 20%, 则表示成像盒当前处于缺墨状态。
步驟 134: 成像盒芯片将成像盒的模拟传感器输出信号设置为第一频率 值如 100k。
成像盒的模拟器的输出信号采用传感器频率的不同取值表示， 其中： 第一频率值如 100k 即为第一信号， 用于表示成像盒当前处于记录材料不充 盈状态； 第二频率值如 33k即为第二信号， 用于表示成像盒当前处于记录材 料充盈状态。
步骤 135: 打印机检测成像盒的模拟传感器的输出信号， 判断检测到的 模拟传感器的输出信号是否为第一频率值如 100k, 或者， 判断检测到的模 拟传感器的输出信号是否由第二频率值如 33k跳变为第一频率值如 100k; 如 果是， 则执行步骤 136; 否则， 执行步骤 132。
步驟 136: 打印机通过墨量状态标识设置模块 34将成像盒的墨量状态标 识设置为第一标识如 EF, 执行步骤 137。
步驟 137: 打印机检测成像盒的墨量状态标识， 判断检测到的墨量状态 标识^ _否为第一标识如 EF; 如果是， 则执行步骤 138; 否则执行步骤 132。
步骤 138: 打印机输出缺墨预警信息， 如输出叹号 "！ " ， 用于提示成 像盒当前缺墨。
可选的， 成像盒的墨量状态标识也在无需打印机参与的情况下， 由成像 盒的墨量状态标识设置模块 34根据步骤 的判断结果而确定。 具体地， 在判断为成像盒的记录材料剩余量小于预设阈值时， 将墨量状态标识设置为 EF。 在这种情况下， 打印机也可结合墨盒的模拟传感器的输出信号和墨量状 态标识的检测结果， 仅在二个检测结果均表示墨盒当前处于缺墨状态时， 输 出缺墨预警信号， 由此提高打印机进行缺墨预警的准确性。
此外， 上述告警信息和记录材料充盈信息的具体表现形式不受限制。 可 采用第一频率值， 第一电流值或第一电压值表示所述告警信息， 采用第二频 率值、 第二电流值或第二电压值表示所述记录材料充盈信息。 以代替用于监 测成像盒墨量的实际传感器的输出， 作为与成像装置进行缺墨预警的固有检 测需求相适配的信号。
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
