Software Design of Distributed Testing System Based on NI PSP Protocol

摘要:

分布式测试系统广泛应用于工业、农业、军事和医疗等众多领域。随着计算机网络技术和分布式处理技术的发展,对分布式测试系统的软件开发提出了更高的要求,既要能满足众多节点的数据传输,同时也要保证在传输过程中数据的准确性。为了简化分布式测试软件的开发,保证数据传输的可靠性,提高软件复用性和开发效率,基于NI Publish-Subscribe Protocol (NI PSP),采用共享网络变量技术设计了可满足多节点大数据量传输要求的分布式测试系统软件。经过实际工程验证,软件实现简单,运行稳定,满足设计要求。

Abstract:

Distributed test system is widely used in industry, agriculture, military and medical fields. With the development of computer network technology and distributed processing technology, higher requirements have been put forward for the software development of distributed test system. It should not only satisfy the data transmission of many nodes, but also ensure the accuracy of data in the transmission process. In order to simplify the development of distributed test software, ensure the reliability of data transmission, and improve the reusability and efficiency of software development, based on NI Publish-Subscribe Protocol (NI PSP), a distributed test system software which can meet the requirements of large data transmission is designed by using shared network variable technology. Through the actual engineering verification, the software is simple to operate and stable in operation, which meets the design requirements.
