摘　　要：图像广播功能不仅可以降低项目建设成本,而且能够提高图像采集设备的利用效率。为有效解除应用程序耦合及简化代码复杂度,本文提出一种基于MQTT通信的图像广播功能的方案。该系统采用EMQX软件搭建MQTT服务端,使用paho-mqtt客户端库创建客户端应用程序,并采用BASE64对图像进行编解码。测试结果表明,该图像广播系统基本达到了设计要求。The image broadcasting function can not only reduce project construction costs,but also improve the utilization efficiency of image acquisition equipment.To effectively decouple applications and simplify code complexity,this article proposes a solution for image broadcasting based on MQTT communication.The system uses EMQX software to build an MQTT server,uses the paho mqtt client library to create a client application,and uses BASE64 to encode and decode images.The test results indicate that the image broadcasting system basically meets the design requirements.
