【摘要】 近年来,随着计算机网络和计算机技术的飞速发展,网络技术已经渗透到计算机应用的各个领域。网络的优势在于资源共享、远程通信及提高整个系统的可靠性。因此,通过网络集中管理各种设备成为一种趋势。而热过载继电器可靠性试验设备和塑壳断路器过载保护可靠性试验设备是对热过载继电器和塑壳断路器进行可靠性指标检测的低压电器设备,为了提高试验效率和便于集中管理,对试验的控制及通讯技术的研究就显得尤为重要。除此之外,还应开发一套实际应用的网络通信软件用于对设备进行管理。本文首先分析了热过载继电器可靠性试验装置和塑壳断路器过载保护可靠性试验设备硬件的相似之处和不同部分,采用星型拓扑结构组建了小型局域网。网络类型采用的是客户/服务器模型,利用Visual Basic 6.0语言开发了基于TCP/IP协议的通信软件,包括客户端和服务器端通信软件。可由服务器集中控制两台设备同时试验,大大提高了试验效率和远程控制的能力,适应了当今社会网络发展的需要,具有一定的实用价值。更多还原

【Abstract】 In recent years, with the rapid development of computer networks and computer technology, network technology has seeped through computer applications in various fields. The advantage lies in network resource sharing, remote communications and enhancing overall system reliability. Therefore, centralized management of devices through network become a trend. The thermal overload relays reliability test device and MCCB reliability test device are used to detect index of thermal over load relays and MCCB. For improving test efficiency and convenient for central management, it is very important to study the control and communication technologies of test. Except that, it is important to develop communication software of central management.This paper analyzed the hardware part of the similarities and differences between thermal overload relays reliability test device and MCCB overload protection devices, formed a small LAN with star topology. Our using the type of network is Client/Server model, and using Visual Basic 6.0 developed the communication software based on the TCP/IP protocol, including client and server communication software. Centralized control may control two test equipments using a server at the same time, greatly improving the efficiency and remote control capacity, to meet the current needs of the development of social networks, have some practical significance.更多还原
