整个系统工作流程可以简单描述如下：系统上电后，首先DSP由flash实现自举，并运行引导程序，之后转入EDMA等待状态，FPGA初始化后等待外部图像采集命令，收到图像采集命令后开始进行图像采集，并对采集到的图像进行预处理，预处理后的图像经过FIFO缓冲，在存储一定量的数据之后，FPGA通过半满信号向DSP发送EDMA请求，等待DSP响应，DSP一旦收到来自FPGA的EDMA请求，立即建立EDMA通道，从FIFO中读取数据到L2存储器，存满一帧图像后DSP开始图像压缩，等待一幅图像压缩完成之后，DSP会向FPGA发送中断信号，FPGA在收到中断信号后开始从 FIFO中读取压缩后的图像数据。一帧数据读完后，判断编码信号是否有效，如果有效则按同样的规则对下一帧图像进行压缩，如果无效则通知DSP结束。

ABB模块07KT92 CS31应用数控系统DCS/PLC可编程控制器使用了近30年的 PLC卡件模块控制器(PLC+ CAN)系统具有 的功能，因此设计人员必须在不断地测试和评估每个部件的功能，从而让整个系统能够与设备无缝集成。因此，使用 PLC卡件模块控制器(CATIA)对一个具有高度可扩展性的 DCS系统至关重要。作为一种标准，它允许用户使用各种功能与各种设备进行通信。通常可以包括：与外部设备的数据通讯；控制开关；操作面板；触摸开关和数字键盘输入/输出输入设置和显示输出状态监测电路控制；命令和控制命令发送。其中 重要的功能是远程网络连接所需传感器、信号发生器、以及控制器。从一个简单的标准程序包中调用这些硬件就可以了。这就是 简单的编程原理，即以计算机作为硬件基础的智能算法来实现这些过程。该功能可以允许使用多种不同颜色或不同种类。使用编程软件可编程接口(PLC)程序，从一个按钮到另一个按钮，或者由数字信号来完成所有其他操作（例如调试）。但是在控制过程中，通常都不会选择输入或输出信号并且可以调节电压，在一定程度上也取决于连接数据（例如设备所要求的数据）。这些功能还可以通过软件进行设置和修改功能来实现自动化。所有这一切都是一种直观 方法来简化或创建一个良好的 DCS系统运行状态过程，实现从输入/输出信号到控制设备动作、自动采集参数并对过程信号进行处理以及对现场事件作出反应、执行命令等所有这些过程都在 PLC中运行。通过编程控制每个模块控制器以及相关的软件都可以实现功能，使用户能够应用这些功能并利用 PLC实现生产目标和控制策略，其特点是：可以用一个特定的输入或输出端口与一个或多个外部设备通讯，也可以通过内部控制模块(CAN)和计算机接口实现。该系统中每个器件（包括逻辑控制和报警功能）都具有一定功能-可以执行命令。

The whole system workflow can be simply described as follows: After the system is powered on, the DSP is bootstrapped by flash first, and the boot program is run, and then it is transferred to the EDMA waiting state. After initialization, the FPGA waits for the external image acquisition command. After receiving the image acquisition command, the image acquisition begins, and the acquired image is preprocessed. After storing a certain amount of data, FPGA sends EDMA request to DSP through half-full signal, waiting for DSP response. Once DSP receives EDMA request from FPGA, it immediately establishes EDMA channel, reads data from FIFO to L2 memory, and starts image compression after storing one frame of image. After an image compression is completed, the DSP sends an interrupt signal to the FPGA, and the FPGA begins to read the compressed image data from the FIFO after receiving the interrupt signal. After reading a frame of data, the encoded signal is judged whether it is valid. If it is valid, the next frame image is compressed according to the same rules. If it is invalid, the DSP is notified to end.

The ABB module 07KT92 CS31 applies the functions of the CNC system DCS/PLC Programmable controllers that have been used for nearly 30 years by the PLC card Module controller (PLC+ CAN) system, so designers must constantly test and evaluate the function of each component, so that the entire system can be seamlessly integrated with the device. Therefore, the use of PLC card module controllers (CATIA) is essential for a highly scalable DCS system. As a standard, it allows users to communicate with a variety of devices using a variety of features. This can typically include: data communication with external devices; Control switch; Operation panel; Touch switch and numeric keypad input/output input Settings and display output status monitoring circuit control; Command and control command sending. Among the important functions are sensors, signal generators, and controllers required for remote network connections. The hardware is called from a simple standard package. This is the simple principle of programming, that is, intelligent algorithms based on computers as hardware to implement these processes. This feature can allow the use of many different colors or different kinds. Using programming software Programmable interface (PLC) programs, all other operations (such as debugging) are done from button to button, or by digital signals. However, in the control process, the input or output signal is usually not selected and the voltage can be adjusted to a certain extent, depending on the connection data (such as the data required by the device). These functions can also be automated through software Settings and modifications. All of this is an intuitive way to simplify or create a good DCS system operation state process, from input/output signals to control equipment action, automatic acquisition of parameters and processing of process signals, as well as responding to field events, executing commands and so on all these processes run in the PLC. By programming control of each module controller and related software CAN achieve functions, users can apply these functions and use the PLC to achieve production objectives and control strategies, which can be: with a specific input or output port to communicate with one or more external devices, can also be achieved through the internal control module (CAN) and computer interface. Each device in the system (including logic control and alarm functions) has a certain function - it can execute commands.
