| 摘 要： | 针对昆明VLBI观测站终端设备(S3数据采集系统)的特殊性,设计在标准的终端控制计算机(Field System)上能够控制相应硬件设备的软件.S3数据采集系统包括SX接收机、中频分配器、视频转换器、时延计数器、噪声控制开关和气象数据自动采集仪.设计过程中,考虑到软件的可读性和可维护性,各种设备分别用相应的子函数来完成具体功能,各子函数由主程序调用.在完成程序安装后,经测试能与S3数据采集系统进行良好的通讯,达到控制各硬件设备的目的及满足实际测控工作的需要.

| Abstract: | A new software design for Kunming VLBI station terminal control system is discussed in this paper.The software can operate on the standard computer(Field System Computer)to control the terminal device($3 Data Acquisition System)without considering its particularity. S3 Data Acquisition System includes Receiver,Intermediate Frequency Distributor,Base Band Converter,Cable Delay Counter,Calibration Signal Switch and Weather Data Auto-acquisition device.Each device is controlled by corresponding sub-function in order to meet the demand of readability and maintainability.The sub-functions can be called by main function.The software can communicate with the S3 Data Acquisition System efficiently and control the terminal device effectively after being installed and tested.Recent observation experiments have validated that the software satisfied the real-time requirement. |
