摘要
针对地面生命保障系统密封舱试验系统内温湿度环境控制的需要,研究与设计了一种采用Agilent VEE虚拟仪器技术和PLC技术相结合的温湿度测控系统。该系统通过PLC软件实时地进行温湿度值的设定和修改并完成温湿度的控制任务,同时将PLC采集到的温湿度信号通过串口完成与PC机的通信,通过Agilent VEE软件实现温湿度信号的存储、显示和打印,完成温湿度的测量。实验结果表明,该系统具有良好的实用性和可靠性。
The temperature- humidity measurement and control system through the combination of Agilent VEE software and Panasonic Electronic Industry＇s PLC technique,for the requirement of the temperature and humidity circumstance control of capsule in the life protection system on ground. This system sets and modifies the value of temperature and humidity real - time and accomplishes the control task of the temperature and humidity in capsule. Meantime, the sign of temperature and humidity,gathered from PLC, correspondences with PC. Through the signs of temperature and humidity memory, display and print, the measurements of temperature and humidity are completed. The experiment results show that the system has good practicability and reliability.
