图 i为本发明实施例中的图像形成系统的功能结构模块图。
根据本实施例的图像形成系统包括图像形成设备的驱动装置 100和图像 形成设备 200。 驱动装置 100将用户文档数据转换成待成像的页数据并发送 给图像形成设备 200。 图像形成设备 200将驱动装置 100发来的待成像的页 数据打印在记录介质上。
驱动装置 100和图像形成设备 200可以通过符合 USB接口、并行接口等 要求的通信线直接连接, 也可以通过网络通信接口来进行数据通信。
驱动装置 100包括数据控制器 150和接口单元 110 (亦称为第二接口单 元) 。 从硬件实体结构角度, 数据控制器 150可由控制器 (例如中央处理器 CPU或微控制单元 MCU) 、 存储器和存储于存储器上的应用程序的结合来 构成。 从功能上划分, 可包括数据处理单元 151、 监控单元 153和虛拟数据 产生单元 154。 为了便于说明, 下面从功能划分的角度进行详细说明。 本领 域技术人员能够明白, 数据处理单元、 监控单元和虚拟数据产生单元可通过 共用中央控制器或存储器等硬件实体来实现, 也可以设置单独使用的 MCU 等硬件来实现。
数据处理单元 151控制文档数据的渲染处理、 控制待成像的页数据的传 输和接收、 控制虚拟数据的产生和发送以及控制驱动装置 100与图像形成设 备 200之间的通信。
监控单元 153用于监控数据处理单元 151中文档数据的渲染处理过程和 待成像的页数据的传输和接收过程, 并在监控到异常情况时采取相应的异常 处理措施。
虚拟数据产生单元 154用于产生虚拟数据, 虚拟数据是用于防止所述图 像形成设备因超过第一预定时长未接收到数据而停止当前成像作业的数据。
接口单元 110可为 USB接口、 并行接口或网络通信接口任意之一,与图 像形成设备 200之间建立第一通道和第二通道。 驱动装置 100通过接口单元 110的第一通道和第二通道与图像形成设备 200进行数据通信。
这样, 驱动装置 100的数据控制器 150可通过第一通道向图像形成设备 200 发送根据待成像的文档数据进行渲染得到的页数据, 通过第二通道向图 像形成设备 200发送虚拟数据。 后续将对此展开详细说明。
图像形成设备 200可包括成像控制器 201、 接口单元 205、 计时器 203、 成像引擎 202和存储单元 204。
接口单元 205 (亦称为第一接口单元) 包括第一端口和第二端口, 分别 利用第一端口和第二端口在图像形成设备 200与其驱动装置 100之间建立第 一通道和第二通道。 这样, 图像形成设备 200通过接口单元 205与驱动装置 100的接口单元 1 10之间可分别通过第一通道和第二通道并发地进行数据通 信, 换而言之, 可以在第一通道发送数据的同时, 在第二通道发送数据, 两 个通道互不干涉。 接口单元 205可以相应地采用为 USB接口、 并行接口或网 络通信接口任意之一, 从而能够与接口单元 110建立连接。
成像控制器 201将从在驱动装置 100和图像形成设备 200之间建立的第 一通道接收的数据作为待成像的页数据, 以及获取来自在驱动装置 100和图 像形成设备 200之间建立的第二通道的数据, 作为虚拟数据。 更具体地, 成 像控制器 201可控制图像形成设备 200的打印处理过程、 控制连接到成像控 制器 201的各个单元、 以及控制图像形成设备 200与驱动装置 100之间的通 成像引擎 202对从第一通道接收的待成像的页数据进行图像形成处理。 更具体地, 成像引擎 202从成像控制器 201接收打印数据, 并在成像控制器 201的控制下将打印数据打印到记录介质上。
存储单元 204可储存从驱动装置 100接收到的待成像的页数据和虚拟数 据, 还可存储实现多种功能的控制程序。
计时器 203对自图像形成设备 200最近一次从第一通道接收到页数据的 时刻或从第二通道接收到虚拟数据的时刻中的较晚时刻起的时长进行计时, 作为第一时长; 其中, 在第一时长达到第一预定时长时, 成像控制器 201迸 行用于停止当前成像作业的超时处理。 第一预定时长是在图像形成设备 200 中预先设定的一个值,其取值可由图像形成设备提供商在设备内固定或设定, 也可以由用户自行设定。
这样, 由于虚拟数据不会从第一通道发来, 而是从第二通道发来, 这使 得图像形成设备 200在通过第一通道接收到页数据时能够立即进行打印, 而 无需判断驱动装置 100从第一通道发来的数据是虚拟数据还是页数据, 从而 简化了图像形成设备的固件开发难度并降低了开发成本。
优选地, 图像形成设备 200的存储单元 204还可迸一步包括第一缓冲器 和第二缓冲器, 分别用于缓存来自所述第一通道和所述第二通道的数据。 这 样, 可进一步提高图像形成设备 200对接收到的数据的响应速度。 第一缓冲 器的容量可相较第二缓冲器大得多。

步骤 S230,驱动装置 100通过所述第一通道向图像形成设备 200发送根 据待成像的文档数据进行渲染得到的页数据。 更具体地, 当接收到用户输入 的打印命令时, 根据用户打印命令确定待成像的文档数据, 并对其进行逐页 渲染以得到页数据。 当渲染得到一页数据时, 驱动装置 100通过所述第一通 道向图像形成设备 200发送该页数据。
更具体地, 数据控制器 150的数据处理单元 151准备开始逐页对用户文 档数据迸行渲染。 当完成一页数据的渲染后, 数据处理单元 151将渲染完成 的该页数据通过接口单元 1 10建立的第一通道发送给图像形成设备 200。
歩骤 S240 ,驱动装置 100通过所述第二通道向图像形成设备 200发送虛 拟数据。 第二通道是不同于发送页数据的第一通道的其他通道, 第二通道可 以用来只发送虚拟数据, 也可以同时发送虚拟数据和其他数据。
步骤 S250, 判断是否发送完成所有页数据, 若判断结果为是, 则进入步 骤 S260以结束处理, 数据处理单元 151停止向图像形成设备 200发送虚拟 数据, 反之, 返回步骤 S230及 S220。 例如, 可通过监控单元 153是否接收 到数据处理单元 151发来的数据发送完成通知来判断是否发送完成所有页数 据。

成像控制器 201对从第一通道接收到的待成像的页数据进行处理后, 发 送给成像引擎 202进行成像处理, 以打印到记录介质上。
步骤 S330, 判断是否完成所有页数据的成像处理, 若判断结果为是, 进 入步骤 S360, 当前成像作业完成, 反之, 返回步骤 S320和 S340。
在步骤 S340中, 成像控制器 201判断自所述图像形成设备 200最近一 次从第一通道接收到页数据的时刻或从第二通道接收到虚拟数据的时刻中的 较晚时刻起的 ^长是否达到第一预定时长, 若判断结果为是, 则进入步骤 S350, 反之返回步骤 S320和 S340以继续接收来自驱动装置 100的数据; 步骤 S350, 成像控制器 201进行用于停止当前成像作业的超时处理。 下面结合图 2和图 3的流程图来进一步详细介绍本实施例的一些步骤。 步骤 S240 中, 特别地, 可在开始当前成像作业时开始通过第二通道向 图像形成设备 200发送虚拟数据。 也可自开始当前成像作业经过了第二预定 时长时开始向图像形成设备 200发送虚拟数据, 其中, 第二预定时长为预先 设定或固定的取值并小于或等于所述第一预定时长。
此外, 还可以在当前作业的渲染过程中第一次出现渲染超时时开始向图 像形成设备 200发送虛拟数据。 即, 可以由监控单元 153对每页数据的渲染 时间计时, 将每页的渲染时间与一个预定渲染超时时间比较, 若某页数据的 渲染时间达到预定渲染超时时间则判断渲染超时, 在第一次出现渲染超时的 时候开始向图像形成设备 200发送虚拟数据。 可见, 图 2中示出的 S220和 S230的时间顺序只是一个例子,步骤 S220和 S230的顺序可以是任意的甚至 并行的。
在开始通过所述第二通道向图像形成设备 200发送虚拟数据之后, 既可 以连续地向图像形成设备 200发送虚拟数据, 也可以以小于或者等于第一预 定时长的周期发送虚拟数据。 具体而言,数据处理单元 151通过接口单元 1 10 的第二通道向图像形成设备 200发送虛拟数据的方式, 可以是周期性地通过 接口单元 1 10的第二通道向图像形成设备 200发送虚拟数据, 向图像形成设 备 200 发送虚拟数据的周期需小于或者等于第一预定时长。 数据处理单元 151 通过接口单元 110 的第二通道向图像形成设备 200 发送虚拟数据的方 式, 也可以是连续不断地通过接口单元 110的第二通道向图像形成设备 200 发送虚拟数据。 由于数据处理单元 151向图像形成设备 200发送页数据和虚 拟数据所采用的通道不一样, 因此允许页数据和虚拟数据的并行发送, 从而 使得根据本发明的图形成方法能解决在同一通道下发送页数据和虚拟数据时 因要处理数据并发问题而带来的处理复杂性。
此外, 在上述驱动装置 100侧的成像方法中, 还可以增加数据处理监控 步骤, 监控成像作业处理过程中有无出错, 若有出错, 则进行停止当前成像 作业的相关处理并释放相应的软硬件资源等成像作业异常处理。 以及进行监 控, 以便在当前打印作业己全部渲染完成、 全部页数据发送完成或者取消当 前打印作业时, 停止通过所述第二通道向图像形成设备 200发送虚拟数据。 监控单元 153可以对一页数据的渲染时间计时, 即监控单元 153在接收 到数据处理单元 151发来的一页数据渲染开始的通知后开始计时, 若在预定 时长 Toutl (第三预定时长) 内未接收到数据处理单元 151 发来的一页数据 渲染完成的通知, 则判断该页渲染出错, 通知数据处理单元 151停止向图像 形成设备 200发送虚拟数据, Toutl为数据处理单元 151形成单个页数据的 最长允许用时。
监控单元 153也可以对一份成像作业的渲染时间计时, 即监控单元 153 在接收到数据处理单元 151发来的成像作业渲染开始的通知后开始计时, 若 在预定时间 Tout2 (第四预定时长) 内未接收到数据处理单元 151 发来的成 像作业渲染完成的通知, 则判断当前成像作业渲染出错, 通知数据处理单元 151停止向图像形成设备 200发送虚拟数据, Tout2为渲染完成一份成像作业 的最长允许用时。 所述 Toutl和 Toui2可以是预先定义好的, 也可以是用户 根据实际打印情况设置的。
监控单元 153还可以监控驱动装置 100和图像形成设备 200之间是否出 现通信异常, 当监控到出现通信异常时通知数据处理单元 151停止向图像形 成设备 200发送虚拟数据。
此外, 在步骤 S220中, 虛拟数据产生单元 154产生的虚拟数据的步骤 可优选为根据根据预设规则产生虚拟数据。 相应地, 在步骤 S320 的获取来 自所述第二通道的数据作为虚拟数据的处理可优选为: 获取来自所述第二通 道的数据; 判断从所述第二通道的获取的数据是否符合预设规则; 在判断为 符合预设规则时, 将所获取的数据作为虚拟数据。
根据预设规则产生虚拟数据有助于图像形成设备 200根据该预设规则来 识别虚拟数据, 这样可以为第二通道中传送其它数据提供方便, 也可以防止 虚拟数据被恶意发送或篡改。
该预设规则可为: 使得虚拟数据包括预设的一组数据中任一或者一预设 的数据 (筒称规则 A) 。
虚拟数据可以是一预设的数据, 例如, 可为数据内容及长度均固定不变 的或者预先设置好的数据。 例如, 可以在虚拟数据产生单元 154中预先存储 一组固定的数据作为静态虚拟数据, 如 0B320000, 当需要向图像形成设备 200发送虚拟数据时, 可由数据处理单元 151从虚拟数据产生单元 154中读 取该静态虚拟数据并通过接口单元 110发送给图像形成设备 200。 将这种情 况下的虚拟数据称为静态虛拟数据。 图像形成设备 200通过第二通道获取到 数据时, 判断所获取到的数据是否符合相应的预设规则 (在本例中, 判断接 收到的数据是否为数据内容及长度均固定不变的或者预先设置好的那个数 据) , 若不符合, 则不将所获取的数据作为虚拟数据, 反之, 将其作为虚拟 数据。
此外, 虚拟数据也可以是一组数据中的任一。 在这种情况下, 每次要发 送虛拟数据时, 虛拟数据产生单元 154可将预设的一组数据中之一作为其产 生的要发送给图像形成设备 200的虚拟数据。 从该预设的一组数据选择一个 数据的方式可以多种多样。例如, 可依次循环选择预设的一组数据中的数据, 作为先后要发送给图像成像设备 200的虛拟数据。 甚至还可随机选择该预设 的一组数据中的数据之一, 作为各次生成的虚拟数据。 可见, 从该预设的一 组数据中选择一个数据的方式可以是任意的。
此外, 该预设规则还可以是: 虚拟数据是根据预设随机数产生规则产生 的数据 (筒称规则 B ) 。 预设随机数产生规则可以是任意的, 只要驱动装置 100和图像形成装置 200两侧相一致即可。 这也可使得虚拟数据在同一作业 的处理期间进行变化, 甚至使得虛拟数据产生单元 154每次产生的虛拟数据 不同。 例如, 假设虚拟数据为一组 8 t的数据, 将虚拟数据产生单元 154设 置成一个遵循预定随机数产生规则的 8bit随机数产生单元, 在数据处理单元 151周期性地向图像形成设备 200发送虛拟数据时, 每个周期所发送的一组 虚拟数据是动态变化的。 图像形成设备 200通过第二通道获取到数据时, 判 断所获取到的数据是否符合相应的预设规则 (在本例中, 判断接收到的数据 是否符合预设随机数产生规则) , 若不符合, 则不将所获取的数据作为虚拟 数据, 反之, 将其作为虚拟数据。
为了进一步提高通信安全, 防止虚拟数据被第三方识别和恶意利用, 该 预设规则还可以是: 虚拟数据包括预设的成像作业属性信息, 该成像作业属 性信息包括成像作业的名称、 文档类型信息、 创建者信息、当前页数据序号、 当前页数据大小和创建时间信息至少之一 (简称规则 C) 。 这样, 使得虚拟 数据可以隨着成像作业名、 文档类型以及成像作业创建信息的动态变化而在 不同成像作业之间动态变化, 甚至还可以在在同一作业的处理期间随着当前 页数据序号和当前页数据大小等信息而变化, 进而有效地提高了驱动装置
100和图像形成装置 200之间通信的安全性。 此时, 图像形成设备 200可类 似地通过判断所获取的数据是否符合相对应的预设规则来判断所获取的数据 是否为虛拟数据。
例如, 假设虚拟数据由四个部分组成, 第一部分随成像作业名称而变、 第二部分随文档类型而变、 第三部分随作业创建时间而变、 第四部分随作业 创建者而变。 数据处理单元 151接收到用户输入的打印命令后, 首先判断当 前作业的文档类型, 记录当前作业的创建时间、 创建者和成像作业名, 并将 这些成像作业属性信息在开始当前成像作业时发送给图像形成设备 200, 图 像形成设备 200接收所述成像作业属性信息并保存在存储单元 204中。 当作 业处理期间, 需要向图像形成设备 200发送虚拟数据时, 数据处理单元 151 将成像作业名称、 文档类型信息、 作业创建者信息和作业创建时间信息发送 给虚拟数据产生单元 154, 虚拟数据产生单元 154根据上述信息来改变上述 四个部分的信息, 而产生虚拟数据。 数据处理单元 151将所生成的虚拟数据 发送给图像形成设备 200。 图像形成设备 200通过第二通道获取到数据时, 判断所获取到的数据是否符合相应的预设规则 (在本例中, 判断接收到的数 据是否为这四部分组成, 各部分的值是否正确) , 若不符合, 则不将所获取 的数据作为虚拟数据, 迸而不触发计时器 203复位。 反之, 将其作为虚拟数 据, 从而触发计时器 203复位。
此外, 预设规则还可以是: 将对上述预设规则 A、 B或 C产生的虚拟数 据进行加密处理后得到的加密后数据作为最终要发送给图像形成设备 200的 虚拟数据 (简称规则 D)。 这样, 图像形成设备 200通过第二通道获取到数据 时, 判断所获取到的数据是否符合相应的预设规则 (在本例中, 通过判断将 所获取的数据进行解密后是否符合在驱动装置!00和图像形成设备 200之间 约定的上述各种预设规则之一来判断该获取的数据是否符合预设规则) , 若 不符合, 则不将所获取的数据作为虚拟数据, 反之, 将其作为虚拟数据。 在 这种情况下, 可以在驱动装置 100和图像形成设备 200中都预先存储一个加 密密钥, 先将虚拟数据产生单元 154产生的数据通过加密密钥和预定的加密 规则来产生虚拟数据, 再将虚拟数据发送给图像形成设备 200; 图像形成设 备 200根据预先存储的密钥来对接收到的虚拟数据进行解密, 再判断解密后 的数据是否满足预先与驱动装置 100约定的预设规则八、 ]8或€, 以识别接 收到是否为期望的虛拟数据,如果不是则表明所接收到的数据可能被窜改过, 图像处理设备 200不将该数据作为虚拟数据, 进而不蝕发 i†时器 203复位。
此外, 预设规则还可以是: 根据规则 D获取的数据及未加密前的经过相 应的预设规则 A、 B或 C之一产生的数据 (简称规则 E)。 也就是说, 在这种 预设规则中, 使得虚拟数据既包括加密前的数据、 也包括加密后的数据。 这 样, 在图像形成设备 200侧, 对接收到的数据进行与规则 D中采用的加密处 理相对应的运算处理后, 可通过将运算得到的数据与加密前数据或加密后数 据进行对比来判断所接收到的数据是否为所期望的虚拟数据、 进靣判断是否 要触发计时器 203复位。 在这种情况下, 可以在驱动装置 100和图像形成设 备 200中都预先存储一个加密密钥, 先将虛拟数据产生单元 154产生的加密 前数据通过加密密钥和预定的加密规则来产生加密后数据, 再将加密后数据 和加密前数据一起作为虛拟数据发送给图像形成设备 200。图像形成设备 200 可以利用预先存储的密钥对接收到的数据中的加密后数据进行解密运算得到 一个解密结果,判断所述解密结果与接收到的数据中的加密前数据是否一致, 若一致则表明所接收到的数据是虚拟数据。 图像形成设备 200还可以调用与 所述加密规则相对应的程序利用预先存储的密钥对接收到的数据中的加密前 数据进行加密运算得到一个加密结果, 判断所述加密结果与接收到的数据中 的加密后数据是否一致,若一致则表明所接收到的数据是所期望的虚拟数据。
此外, 预设规则还可以是: 在上述规则 A至 E中任一种虚拟数据中增加 虚拟数据标识, 作为最终要发送给图像形成设备 200 的虚拟数据 (简称规则 F), 虛拟数据标识用于区分虚拟数据与在同一通道传输的其它类型数据。 这 样, 图像形成设备 200在接收到所述数据后, 首先根据虚拟数据标识判断接 收到的数据是否为虚拟数据, 再判断该数据中的其它部分的数据是否也符合 与驱动装置 100事先约定的预设规则 A、 B、 C, D或 E中之一, 若判断为从 第二通道接收到的数据中没有虚拟数据标识或者判断为该数据中除虚拟数据 标识外的其它部分数据不符合与驱动装置 100事先约定的预设规则 A、 B、 C、 D或 E中之一, 则不将该数据作为虚拟数据, 进而不触发 it时器 203复位。
图 4为根据一实例的虚拟数据产生单元的结构示意图。 在采用规则 Ε Ά 与规则 E中采用规则 B来生成待加密数据、且将加密后的数据与虚拟数据标 识一并作为最终向图像形成设备 200发送的虚拟数据时, 虚拟数据产生单元 154可进一步包括密钥存储单元 1541、随机数产生单元 1542和加密运算单元 1543。 结合图 4对通过加密方式来产生虚拟数据的过程作进一步说明。
密钥存储单元 1541储存一个加密用的密钥 K; 随机数产生单元 1542产 生数据 Rt; 加密运算单元 1543根据数据处理单元 151的控制, 加密运算单 元 1543对密钥存储单元 1541 中的密钥和随机数产生单元 1542产生的数据 Rt通过预先设定的加密算法迸行加密来产生虚拟数据 Dt。
所述加密运算单元 1543所采用的加密算法可以是基于 Hash的算法, 例 如 MD5,SHAi,SHA256,SHA5 i2算法, 也可以是其他加密算法。 由于随机数 产生单元 1542 产生的是一系列动态变化的数据, 因此每次通过加密运算单 元 1543产生的加密数据不同, 迸而提高了通信安全性。
然后, 驱动装置 100将加密后的数据与虚拟数据标识一并作为最终的虚 拟数据通过第二通道向图像形成设备 200发送。
图像形成设备 200从第二通道获取到的数据后, 首先判断所获取的数据 中是否包括虚拟数据标识, 若判断为不包括, 则判断为该获取的数据不是虚 拟数据。 反之, 若判断为包括, 再对接收到的数据中除虚拟数据标识以外的 数据进行解析。即成像控制器 201从存储单元 204调用与加密运算单元!543 所采用的加密算法相对应的程序利用存储单元 204中存储的密钥 K对上述除 虚拟数据标识以外的数据中的已加密部分进行解密运算, 得到一个解密结 果。
在所获取的数据中即包括加密前数据又包含加密后数据的情况下, 则判 断解密结果与所获取的数据中的加密前数据部分是否相一致; 在所获取的数 据中仅包括加密后的数据的情况下, 则进一步判断解密结果是否与根据与驱 动装置 100预先约定的规则 A至 C中之一确定的数据相一致。若判断为相一 致,则说明所获取的数据是未被篡改的数据,可作为虚拟数据以将 时器 203 复位, 反之, 不将该获取的数据作为虚拟数据, 从而不对计^器 203进行复 根据上述处理, 由于第三方不知道本发明中的图像形成系统所使用的密 钥, 即使第三方截获驱动装置 100发送给图像形成设备 200的虚拟数据, 也 无法获知这些数据的含义; 即使虚拟数据被第三方窜改, 也能被图像形成设 备 200所识别, 从而提高了驱动装置 100和图像形成设备 200之间的通信安 全, 能防止第三方的对虛拟数据的恶意攻击和利用。
顺便说明的是, 本发明中提及的"接收到 "一般指"接收完成", 但不限于 此, 也可以指接收过程中的任一时刻, 以能够实施本发明技术方案为准。
本发明的驱动装置 100可以为例如安装有图像形成设备 200的驱动程序 的计算机、 个人数字终端 (PDA) 、 移动智能终端等计算装置。 虚拟数据产 生单元 54中的密钥存储单元 1541、 随机数产生单元 1542和加密运算单元 1543可以通过计算装置中的存储器、加密程序和中央控制器的相互结合使用 来实现, 也可以通过一能够接入计算装置的外部设备来实现。 例如, 一个支 持 USB接口且能够根据预设规则生成加密后虚拟数据的外部设备。这样, 可 提高密钥的私密性。
本实施例的驱动装置 100还可以通过如下方法实现。 更具体地, 将存储 了用于实现上述实施例的功能的软件的程序代码的存储介质 (或者记录介质) 应用到系统或设备。 系统或设备的计算机 (CPU或 MPU)读出并执行存储在存 储介质中的程序代码。 在这种情况下, 从存储介质读出的程序代码实现了上 述实施例的功能, 并 ϋ存储该程序代码的存储介质组成了本发明。 当计算机 执行读出的程序代码时, 实现上述实施例的功能。 并 ϋ , 本发明包括这种情 况: 在计算机上运行的 OS (操作系统)等基于程序代码的指令进行部分或者 全部的实际处理, 从而实现上述实施例中驱动装置的功能。
