摘　　要：超声成像后期数据处理复杂度高,时效性不足。介绍了一种基于TCP协议和LabVIEW技术的网络分布式计算系统实现方法,充分利用分布广泛的空闲网络计算机资源,在任何时刻,系统能够自适应地管理主从机网络连接、协调已连接的主从机间任务分配、获取从机返回计算结果。以达到更快速地完成超声成像的目的。详细阐述了该系统的实现过程,并通过该方案实现了工件截面的快速成像。与FPGA等通过硬件进行并行计算的方法相比,该方法充分利用现有资源,通过软件功能的增加达到快速计算的目的,降低了系统的成本。The complexity of the calculation of a large amount of data processing applications like ultrasonic imaging system leads to a bad effectiveness of the system. A network distributed computing system based on the TCP protocol and virtual instrument technology is introduced to achieve the target for full use of the wide distribution network of computer resources,through the distributed network computing solutions,in any time,adaptive master-slave network connections will be established,and the connected matser-slaver machines can handle with the task allocation,and slave machines return the calculated results and other issues in order to achieve the purpose of computing tasks more quickly. Finally,the ultrasonic phased array imaging system is implemented quickly with this solution. Compared to FPGA,this method achieves the target for fast computing by fully using the available resources without adding any hardware,which can save a lot of cost.
