| 针对纸张印刷的套准误差检测系统在网络传输上精度不足、效率低、实时性差等问题，提出了基于用户数据报协议（UDP）的传输策略，设计并构建了套准误差检测系统通信网络。首先，结合印刷套准检测系统的特点及网络传输需求，创建了套准色标图像传输和套准误差数据传输2个独立线程；其次，在色标图像传输方面，解析BMP格式的位图图像数据，定义传输机制，解决了图像数据报乱序和丢失问题；在误差数据传输方面，定义套准误差报文格式，搭建了套准误差数据传输线程用于套准控制机构实时调整；最后，通过网络抓包，对构建的套准误差检测系统通信网络进行测试。结果显示，构建的双线程通信网络在图像数据传输过程平均传输速率达120 Mbps，端到端延迟控制在5.2 ms 以内，丢包率低于0.01%。 |
| Abstract: |
| In view of the problems such as insufficient accuracy， low efficiency and poor real-time performance of the detection system for the registration error of paper printing in network transmission， a transmission strategy based on user datagram protocol （UDP） was proposed， and a communication network for the registration error detection system was designed and constructed. Firstly， in combination with the characteristics of the printing registration detection system and the requirements of network transmission， two independent threads for registration color mark image transmission and registration error data transmission were created. In terms of color mark image transmission， the bitmap image data with BMP format was analyzed， the transmission mechanism was defined， and the problems of data disorder and loss in image data were solved. In terms of error data transmission， the registration error message format was defined， and a registration error data transmission thread was built to enable the registration control mechanism to adjust in real time. Through network packet capture， the constructed communication network for the registration error detection system was tested. The results showed that the average transmission rate of the image data in the transmission process of the constructed dual-thread communication network reached 120 Mbps， the end-to-end delay was controlled within 5.2 ms， and the packet loss rate was less than 0.01%. |
