【摘要】：隨著天文觀測領(lǐng)域中射電望遠鏡的高速發(fā)展,球面射電望遠鏡的應(yīng)用越來越廣泛,大口徑球面射電望遠鏡對提高觀測性能有重要意義,FAST項目應(yīng)運而生。在FAST項目中,需要控制各個反射面單元的位置使整個球狀反射面精確動態(tài)成型,將接收到的宇宙射電信號準確反射給饋源,完成各種天文觀測目標。所以,設(shè)計一個可以控制所有反射面單元位置的快速、方便、穩(wěn)定的上位機控制系統(tǒng)非常重要。 基于Qt的跨平臺FAST主網(wǎng)反射面上位機控制系統(tǒng)是應(yīng)用于FAST項目的10：1縮比密云模型系統(tǒng)中的,目的是為FAST項目提供技術(shù)參考,搭建實際驗證平臺。本系統(tǒng)采用Qt技術(shù)開發(fā),跨平臺特性強,性能優(yōu)異,系統(tǒng)穩(wěn)定,界面友好。在通信方面,使用TCP協(xié)議進行整網(wǎng)通信、命令發(fā)送和數(shù)據(jù)采集,設(shè)計了命令回執(zhí)和心跳包等機制保障了通信的穩(wěn)定性,實現(xiàn)了節(jié)點運動、上下限位報警、自動觀測等功能。在數(shù)據(jù)處理方面,使用基于ODBC的數(shù)據(jù)庫驅(qū)動,實現(xiàn)賬號管理、地理信息處理和節(jié)點數(shù)據(jù)記錄、篩選和分析的功能,同時對上位機控制系統(tǒng)的所有操作進行記錄,提高安全性。在安全方面,設(shè)計備份功能,使用備份PC實時的對控制PC進行數(shù)據(jù)備份,保證控制PC出問題時系統(tǒng)的穩(wěn)定運行。在UI方面,使用了傳統(tǒng)GUI和新一代GUI兩種方案,不僅保障了功能,還大大提高了界面友好程度,基于Qt Quick技術(shù)的新一代GUI方案可以便捷的實現(xiàn)各種動態(tài)效果,是未來軟件的發(fā)展方向。 FAST上位機控制系統(tǒng)的研發(fā)過程經(jīng)過了兩次的現(xiàn)場調(diào)試,修復了各種細節(jié)錯誤。在通信穩(wěn)定性、控制功能實現(xiàn)、連接電機運動和數(shù)據(jù)庫處理等所有方面都達到了設(shè)計要求。FAST上位機控制系統(tǒng)目前仍在密云模型中運行使用,也將為FAST項目貴州現(xiàn)場的建設(shè)提供經(jīng)驗,推動FAST項目的進一步發(fā)展。
[Abstract]:With the rapid development of radio telescopes in the field of astronomical observation, the application of spherical radio telescopes is becoming more and more extensive. In the FAST project, it is necessary to control the position of each reflector unit so that the whole spherical reflector can be precisely shaped, and the received cosmic radio signal should be accurately reflected to the feed to complete various astronomical observation targets. Therefore, it is very important to design a fast, convenient and stable upper computer control system which can control the position of all reflector units. The control system of the reflection surface of cross-platform FAST main network based on Qt is applied to the 10:1 reduction ratio Miyun model system of the FAST project. The purpose of this system is to provide the technical reference for the FAST project and to build the practical verification platform. The system is developed by Qt technology, with strong cross-platform characteristics, excellent performance, stable system and friendly interface. In the aspect of communication, the TCP protocol is used for the whole network communication, command sending and data acquisition, and the mechanism of command receipt and heartbeat packet is designed to ensure the stability of communication, and the functions of node movement, upper and lower limit alarm, automatic observation are realized. In the aspect of data processing, the database driver based on ODBC is used to realize the functions of account management, geographic information processing and node data recording, screening and analysis. At the same time, all operations of the host computer control system are recorded to improve the security. In the aspect of security, the backup function is designed, and the backup PC is used to backup the data of the control PC in real time to ensure the stable operation of the system when the control PC is out of order. In the aspect of UI, the traditional GUI and the new generation GUI are used, which not only guarantee the function, but also greatly improve the interface friendly degree. The new generation GUI scheme based on Qt Quick technology can realize all kinds of dynamic effects conveniently. The research and development process of FAST PC control system has been tested twice, and all kinds of detail errors have been fixed. In all aspects, such as communication stability, control function realization, connection motor motion and database processing, etc., the upper computer control system of fast is still running in Miyun model. It will also provide experience for the construction of FAST project in Guizhou, and promote the further development of FAST project.
