基于VEE與Nport的控溫儀狀態(tài)參數(shù)遠程監(jiān)控系統(tǒng)設(shè)計

System design for remote monitoring of temperature controller's state parameters based on VEE and Nport

  • 摘要: 為了減輕試驗人員勞動強度，避免人為操作失誤導(dǎo)致的數(shù)據(jù)失真與控溫風(fēng)險，提高航天器真空熱試驗自動化水平，設(shè)計了基于VEE與Nport的控溫儀狀態(tài)參數(shù)遠程監(jiān)控系統(tǒng)。利用NPORT-5610將RS-232協(xié)議轉(zhuǎn)換為TCP/IP協(xié)議，使控溫儀成為具備網(wǎng)絡(luò)接口的組網(wǎng)儀器，采用VEE可視化編程語言開發(fā)了系統(tǒng)軟件，實現(xiàn)了計算機對控溫儀狀態(tài)參數(shù)的遠程監(jiān)控。該系統(tǒng)結(jié)構(gòu)模型合理，軟硬件設(shè)計可行，具有靈活的擴展性和伸縮性，曾在某型號航天器真空熱試驗中成功應(yīng)用。

     

    Abstract: 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.
