现有技术中，随着大型高端多功能一体打印机的性能不断提升的同时，单个主控芯片(SoC)处理速度往往很容易达到极限，无法并行处理高速打印、扫描事务，无法达到多功能一体打印机的高性能要求，导致成像速度慢，影响用户体验。
针对上述问题，本发明实施例提供一种图像形成装置，基于设置主控制系统和子控制系统，提升了系统控制性能，缩短了成像速度时间，有利于多功能一体打印机并行处理高速打印、扫描事务。以下进行详细说明。
参见图1，为本发明实施例提供的一种图像形成装置100的结构示意图。如图1所示，该图像形成装置100包括主控制系统101、子控制系统102、扫描控制单元103、扫描单元104及控制面板105。其中，主控制系统101，例如SoC(System on Chip，片上系统)，被配置为图像形成装置100的中央处理单元，并且接收来自控制面板105中的面板操作指令或者来自外部输入的扫描控制命令。子控制系统102，例如SoC(System on Chip，片上系统)，接收来自主控制系统101传输的扫描启动指令，并基于扫描启动指令，输出控制扫描控制单元103能够执行控制扫描单元104执行图像扫描操作的控制指令。其中，子控制系统102还接收扫描单元104输出的扫描图像，并将扫描图像转换为主控制系统101能够识别并打印或者输出至外部装置106的扫描文件。图像扫描操作的具体过程在下文中进行详细介绍。
其中，主控制系统101和子控制系统102是两个独立的片上系统(SoC，System on Chip)，两者硬件上相互独立，并且可以同时运行。需要说明的是，本实施例提到的主控制系统、子控制系统、第一子控制系统、第二子控制系统仅仅是为了本领域技术人员更容易理解本发明，并非是对其进行限制；例如，主控制系统的对应SoC的性能参数并不一定必须要要比子控制系统对应的SoC的性能参数高；这些不同的SoC可以结合具体需求，可以选择为相同型号或者不同型 号。
本发明实施例提供的技术方案具有以下技术效果：
通过设置两个系统(主控制系统101、子控制系统102)，通过主控制系统101作为图像形成装置100的中央处理单元，接收扫描启动信号及扫描文件，通过子控制系统102输出控制扫描控制单元103能够执行控制扫描单元104执行图像扫描操作的控制信号，使得子控制系统102分担了主控制系统101的控制操作，减轻了主控制系统101的控制操作压力，相比于单个主控芯片的多功能一体打印机，提升了系统控制性能，更有利于多功能一体打印机并行处理高速打印、扫描事务。
参见图2，为本发明实施例提供的一种图像形成装置的成像控制方法流程示意图。该方法可应用于图1所示的图像形成装置100，如图2所示，其主要包括以下步骤。
步骤S201：主控制系统接收来自控制面板中的面板操作指令或者来自外部输入的扫描控制命令。
具体地，图像形成装置100的主控制系统101通过控制面板105或外部输入，如外部装置106，接收用户发送的面板操作指令或扫描控制命令。
步骤S202：子控制系统接收来自主控制系统传输的扫描启动指令，并基于扫描启动指令，输出控制扫描控制单元能够执行控制扫描单元执行图像扫描操作的控制指令。

具体地，主控制系统101接收到面板操作指令或扫描控制命令后，将扫描启动指令传输到子控制系统102，子控制系统102基于主控制系统101的扫描启动 指令，产生并输出控制扫描控制单元103能够执行控制扫描单元104执行图像扫描操作的控制指令。
扫描单元104包括具体的扫描传感器、控制扫描传感器移动的马达、与扫描传感器配合的模数转换器等，扫描传感器包括但不限于：CIS((contact image sensor，接触式图像传感器)、CCD(Charge Coupled Device,电荷耦合器件)。扫描控制单元103能够将子控制系统102输出的控制指令，转换为控制扫描单元的控制信号；例如，子控制系统102输出启动单面扫描、双面扫描和对应扫描图像尺寸等；扫描控制单元103根据这些控制指令，转换成马达启动时刻、行程，扫描传感器对应点灯时刻、数据输出方式等控制信号。
步骤S203：子控制系统接收扫描单元输出的扫描图像，并将扫描图像转换为主控制系统能够识别并打印或者输出至外部装置的扫描文件。
具体地，扫描控制单元103在接收到子控制系统102的控制指令后，基于控制指令，产生并输出控制扫描单元104执行图像扫描操作的控制信号，扫描单元104基于该控制信号执行相应的图像扫描操作，并将扫描图像输出到子控制系统102，子控制系统102接收到扫描图像后，可以转换成主控制系统101能够识别并打印的待打印文件，或者转换成输出到外部装置106(如PC、智能电话、服务器等)的供用户可视的扫描文件。
参见图3，为本发明实施例提供的一种图像形成装置的主控制系统功能单元示意图。主控制系统301包括主控单元302、第一存储单元303、第一内存单元304、控制面板305、接口单元306。用户通过控制面板305或者与接口单元306连接的外部装置下发面板操作指令或扫描控制命令给到主控单元302，图像形成装置进行上述步骤S201-S203后，子控制系统可以将从扫描单元获得的扫描图像，传输给主控制系统301的第一存储单元303或第一内存单元304中存储。其中，在需要打印时，存储在第一内存单元304，以便后续做打印处理；在需要输出到外部装置时，存储在第一存储单元303，用户需要时再从第一存储单元303调出 扫描图像，输出给外部装置。
另外，在彩色逐份打印或者大容量打印文档时，第一存储单元303可以作为缓存，由此缓解主控制系统301的压力，不会出现打印停顿，保证打印速度。
在一种可能的实现方式中，主控制系统301还可以包括用于执行其他功能操作相关的单元模块等，例如可能包括电源管理单元，用于主控制系统301的电源供给或者给子控制系统的电源供给；又例如可能包括温度检测单元，用于实现主控制系统301获得图像形成装置内部的温度信息或图像形成装置外部的环境信息。
在一种可能的实现方式中，第一存储单元303可以是固态存储器(简称eMMC，Embedded Multi Media Card)、固态硬盘(简称SSD，Solid State Disk或Solid State Drive)、或者混合硬盘(简称HDD，HHD:Hybrid Hard Disk)等。第一内存单元304可以是DDR存储器(Double Data Rate SDRAM，双倍速率同步动态随机存储器)、SDRAM(synchronous dynamic random-access memory，同步动态随机存取内存)等。与图像形成装置连接的外部装置通过接口单元306连接，接口单元306可以是有线方式，例如：有线方式包括但不限于通用串行总线(Universal Serial Bus，简称：USB)方式；作为另一种可选方案，接口单元306也可以是无线方式，例如：无线方式包括但不限于无线局域网(wirelesslocal area networks，简称：WLAN)、蓝牙(bluetooth，简称：BT)、近距离无线通信技术(near field communication，简称：NFC)和红外技术(infrared，简称：IR)。
参见图4，为本发明实施例提供的一种图像形成装置的子控制系统功能单元示意图。子控制系统401包括子控单元402、第二存储单元403、第二内存单元404。
子控单元402控制扫描控制单元执行控制扫描单元执行图像扫描操作。具体的，图像扫描操作是扫描控制单元根据子控单元402下发的控制指令，控制启动扫描马达，驱动扫描单元读取原稿图像。扫描控制单元还包括控制位置传感器检 测扫描单元位置、纸张宽幅、开盒盖检测、ADF走纸检测等位置检测。
在一种可能的实现方式中，子控制系统401还可以包括用于执行其他功能操作相关的单元模块等，例如可能包括电源管理单元，用于子控制系统的电源供给。同理，子控制系统401中还可以包括用于执行其他功能操作的相关的单元模块等，在此不再赘述，在本发明实施例中亦不对子控制系统401所包括的单元模块进行限定。
在一种可能的实现方式中，第二存储单元403可以是固态存储器(简称eMMC，Embedded Multi Media Card)、固态硬盘(简称SSD，Solid State Disk或Solid State Drive)、或者混合硬盘(简称HDD，HHD:Hybrid Hard Disk)等。第一内存单元404可以是DDR存储器(Double Data Rate SDRAM，双倍速率同步动态随机存储器)、SDRAM(synchronous dynamic random-access memory，同步动态随机存取内存)等。
扫描单元读取图像后，发送到子控制系统401的第二存储单元403进行存储，并调用第二内存单元404进行图像处理。图像处理后的图像为直接被转换为主控制系统能够识别并打印或者输出至外部装置的扫描文件。其中，图像处理包括：图像像素增强、图像像素打印数据处理、前端校正、图像压缩的一种或多种。
其中，子控制系统401中具备第二内存单元404及其内存带宽，通过子控制系统401对扫描图像进行预先图像处理，并转换为主控制系统能够识别并打印或者输出至外部装置的扫描文件，相比于单个主控芯片的多功能一体打印机，加快了图像形成装置的系统与其内存之间的写入读出速度，缩短了成像速度时间，在需要进行多页或多份复印的情况下，更有利于多功能一体打印机并行处理高速打印、扫描事务。
参见图5，为本发明实施例提供的另一种图像形成装置的结构示意图。图像形成装置500还包括打印引擎控制单元507、打印单元508。打印引擎控制单元507直接与主控制系统501连接，并且通过主控制系统501与子控制系统502隔 离，在子控制系统502断电或损坏时，主控制系统501可以继续控制打印引擎控制单元507处理待打印图像数据。换句话说，在子控制系统502断电或损坏时，主控制系统501将打印数据发送到打印引擎控制单元507，打印引擎控制单元507控制打印单元508执行打印操作。
具体的，如图5所示，该图像形成装置500包括主控制系统501、子控制系统502、扫描控制单元503、扫描单元504及控制面板505、打印引擎控制单元507、打印单元508。其中，主控制系统501，例如SoC(System on Chip，片上系统)，被配置为图像形成装置500的中央处理单元，并且接收来自控制面板505中的面板操作指令或者来自外部输入的扫描控制命令。子控制系统502，例如SoC(System on Chip，片上系统)，接收来自主控制系统501传输的扫描启动指令，并基于扫描启动指令，输出控制扫描控制单元503能够执行控制扫描单元504执行图像扫描操作的控制指令。其中，子控制系统502还接收扫描单元504输出的扫描图像，并将扫描图像转换为主控制系统501能够识别并打印或者输出至外部装置506的扫描文件。在需要将扫描图像进行打印操作时，主控制系统501将打印数据发送到打印引擎控制单元507，打印引擎控制单元507控制打印单元508执行打印操作。另外，在子控制系统502断电或损坏时，由于打印引擎控制单元507通过主控制系统501与子控制系统502隔离，主控制系统501可以继续控制打印引擎控制单元507处理待打印图像数据。换句话说，在子控制系统502断电或损坏时，不影响用户的打印操作。
在一种可能的实现方式中，主控制系统501将打印数据发送到打印引擎控制单元507的同时，还将打印数据存储在主控制系统501的存储单元中，在逐份复印或逐页复印时，一边进行扫描操作的同时执行打印操作，可以缩短成像速度时间，有利于多功能一体打印机并行处理高速打印、扫描事务。
参见图6，为本发明实施例提供的一种子控制系统断电或损坏的判断处理流程示意图。子控制系统断电或损坏的判断处理流程：步骤S601，主控制系统根据 子控制系统提供的反馈信息判断子控制系统是否断电或损坏。步骤S602，若子控制系统断电或损坏，则主控制系统通知操作面板或外部设备提示用户“扫描系统故障，但不影响打印操作”，或者以其他形式提示扫描系统故障，但还可以进行打印操作，例如无操作面板的图像形成装置会通过亮灯、不同颜色的灯、灯闪烁的次数或时间长短等一种或多种方式来表示。步骤S603，打印引擎控制单元根据用户指令，处理待打印数据。其中，用户指令是打印控制指令，待打印数据可以是已存储在第一存储单元的待打印数据，也可以是用户新下发到主控制系统的打印任务。步骤S604，若子控制系统没有断电或损坏，则子控制系统可正常进行扫描操作。步骤S605，扫描控制单元根据用户指令，扫描原稿图像。步骤S606，当用户下发了复印的操作指令或者下发了将存储的扫描原稿图像进行打印的操作指令时，进入步骤S603。步骤S603，打印引擎控制单元根据用户指令，处理待打印数据。若用户没有下发复印的操作指令或者将存储的扫描原稿图像进行打印的操作指令，结束流程。
参见图7，为本发明实施例提供的另一种图像形成装置700的结构示意图。图像形成装置700可以包括至少两个子控制系统。子控制系统具体可以是SoC(System on Chip，片上系统)，两个子控制系统可以是相同的，也可以是不同的。第一子控制系统702通过第一扫描控制单元703控制第一扫描单元704执行第一图像扫描操作，第二子控制系统707通过第二扫描控制单元708控制第二扫描单元709执行第二图像扫描操作，第一子控制系统702、第二子控制系统707分别与主控制系统701电连接，第一扫描控制单元703连接第一子控制系统702，第二扫描控制单元708连接第二子控制系统707。
第一扫描控制单元703为第一扫描引擎控制单元，根据图像扫描操作的控制指令，读取原稿图像的第一面，以获得第一扫描图像。第二扫描控制单元708为第二扫描引擎控制单元，根据所述图像扫描操作的控制指令，读取原稿图像的第二面，以获得第二扫描图像。
在一种可能的实现方式中，第一子控制系统702控制第一扫描控制单元703执行第一图像扫描操作；同时，第二子控制系统707控制第二扫描控制单元708执行第二图像扫描操作。
具体的，在用户从控制面板705或者通过外部装置706下发双面扫描或者双面复印的面板操作指令或控制命令时，主控制系统701同时控制第一子控制系统702和第二子控制系统707进行图像扫描操作。第一子控制系统702通过第一扫描引擎控制单元703，根据图像扫描操作的控制指令，控制第一扫描单元704读取原稿图像的第一面。同时，控制第二子控制系统707通过第二扫描引擎控制单元708，根据图像扫描操作的控制指令，控制第二扫描单元709读取原稿图像的第二面。扫描完成后，第一子控制系统702接收到原稿图像的第一面，即第一扫描图像，第一子控制系统702对第一扫描图像进行图像处理。同时，第二子控制系统707接收到原稿图像的第二面，即第二扫描图像，第二子控制系统707对第二扫描图像进行图像处理。然后，第一子控制系统702将第一扫描图像发送到主控制系统701，同时，第二子控制系统707将第二扫描图像发送到主控制系统701。主控制系统701对接收到的第一扫描图像和第二扫描图像进行正反面排序，形成扫描文件或者发送到打印引擎控制单元进行打印操作。
另外，当需要单面扫描时，即用户从控制面板705或者通过外部装置706下发单面扫描或单面复印面板操作指令或控制命令时，主控制系统701可以只控制其中一个子控制系统进行图像扫描操作，如：只控制第一子控制系统702通过第一扫描引擎控制单元703，根据图像扫描操作的控制指令，控制第一扫描单元704读取原稿单面图像；或者只控制第二子控制系统707通过第二扫描引擎控制单元708，根据图像扫描操作的控制指令，控制第二扫描单元709读取原稿单面图像。
