基于VEE与Nport的控温仪状态参数远程监控系统设计

摘要

为了减轻试验人员劳动强度,避免人为操作失误导致的数据失真与控温风险,提高航天器真空热试验自动化水平,设计了基于VEE与Nport的控温仪状态参数远程监控系统.利用NPORT-5610将RS-232协议转换为TCP/IP协议,使控温仪成为具备网络接口的组网仪器,采用VEE可视化编程语言开发了系统软件,实现了计算机对控温仪状态参数的远程监控.该系统结构模型合理,软硬件设计可行,具有灵活的扩展性和伸缩性,曾在某型号航天器真空热试验中成功应用.%To relieve the work load of test operators, and avoid the distortion of the temperature data and the risk of temperature control failure due to human errors, a system is designed for remote monitoring of temperature controller's state parameters based on VEE and Nport, which may improve the precision, the efficiency, and the automation level of the spacecraft vacuum thermal test. The NPORT-5610 serial server is applied to do the protocol conversion between RS-232 and TCP/IP, which serves as a serial port for the network transmission. VEE, a visual programming language, is used to develop the system software. The established remote monitoring system, with reasonable structure and flexibility in its software and hardware design, enjoys good extensibility, and has been successfully applied in a vacuum thermal test for a certain spacecraft model.
