摘要
随着计算机技术的发展和工业设备的不断更新,铁路货车故障轨边图像检测系统(TFDS)也在根据应用需求不断进行改进和完善。针对系统中有多路相机并行采集这一需求,为了缓解单台计算机的CPU和内存的压力,避免频繁读写硬盘数据造成宕机,采用了基于Socket的TCP传输协议设计实现了主辅机采集模式。设计的断网重传机制可以有效应对网络通信异常的情况,通过一台主机控制多个辅机采集图像和图像传输,减少单台计算机的压力同时又使得系统易于扩展,具有较强的稳定性和适应性。
With the development of computer technology and industrial equipment,trouble of running freight train detection system( TFDS) is also constantly improving and perfecting according to application requirements. In order to reduce the pressure of the CPU and memory of a single computer and avoid the frequent reading and writing of hard disk data,the Socket-based TCP transmission protocol is designed to realize the master-slave acquisition mode. The broken network retransmission mechanism designed in this paper can effectively cope with the abnormal communication between networks. It can control the image transmission of multiple slave machines through one host,reducing the pressure of a single computer,making the system easy to expand,and it has good stability and adaptability.
