【摘要】：隨著時代的發(fā)展，測試環(huán)境越來越復雜,對測試系統(tǒng)提出的要求也越來越高。分布式測試系統(tǒng)能夠通過局域網(wǎng)對位于不同位置的測試設(shè)備進行集中管理，滿足新形勢下對測試系統(tǒng)提出的要求，成為當前測試領(lǐng)域研究的熱點。無線通信技術(shù)具有有線數(shù)據(jù)通信所無法比擬的便捷性，在近年來得到突飛猛進的發(fā)展，因此研究基于無線的分布式測試系統(tǒng)具有非常重要的實踐意義。本文介紹一種基于WLAN的無線分布式測試系統(tǒng)，成功將無線通信技術(shù)與分布式測試系統(tǒng)融合到一起，充分發(fā)揮分布式測試系統(tǒng)便于集中管理的優(yōu)點，結(jié)合無線靈活性的特點，使得測試系統(tǒng)完全勝任復雜場信號的測試，降低了系統(tǒng)構(gòu)建成本，解決了布線困難、組網(wǎng)不便以及擴展性差的問題。 本文主要對測試節(jié)點的設(shè)計和無線網(wǎng)絡構(gòu)建進行了研究。首先介紹了分布式測試的發(fā)展與現(xiàn)狀，而后對分布式測試系統(tǒng)的組成進行了詳細介紹，，為了解決有線傳輸靈活性差帶來的問題，提出了基于WLAN的無線分布式測試系統(tǒng)。對測試系統(tǒng)的構(gòu)建做了主要研究，并對網(wǎng)絡拓撲結(jié)構(gòu)進行選擇，隨后重點介紹了測試節(jié)點的設(shè)計，包括無線模塊的選型和接口電路的設(shè)計，并對測試節(jié)點的測試性能和無線傳輸性能進行了試驗。通過學習WLAN組網(wǎng)的相關(guān)理論，對無線鏈路損耗、覆蓋方式、地址分配等做了相應的研究，隨后根據(jù)項目需求對相關(guān)的無線設(shè)備進行選型，搭建了基于WLAN網(wǎng)絡的無線分布式測試系統(tǒng)，最后通過試驗對無線網(wǎng)絡的相關(guān)性能，如覆蓋角度、傳輸速率等指標進行測試。試驗結(jié)果表明該系統(tǒng)擁有很好的可靠性和穩(wěn)定性，完全滿足課題的需求，對于惡劣環(huán)境下的場信號測試有著重要的應用價值。
[Abstract]:With the development of the times, the test environment is becoming more and more complex, and the requirements of the test system are becoming higher and higher. The distributed test system can centrally manage the test equipment in different locations through local area network (LAN) and meet the requirements of the test system in the new situation. It has become a hot research topic in the field of testing. Wireless communication technology is more convenient than wired data communication, and has been developed rapidly in recent years. Therefore, it is of great practical significance to study distributed testing system based on wireless. In this paper, a wireless distributed testing system based on WLAN is introduced. The wireless communication technology and distributed test system are successfully combined together, and the advantages of centralized management of distributed test system are fully brought into play, and the characteristics of wireless flexibility are combined. The test system is fully capable of testing complex field signals, reduces the cost of system construction, and solves the problems of difficult wiring, inconvenient networking and poor expansibility. This paper mainly studies the design of test nodes and the construction of wireless network. This paper first introduces the development and present situation of distributed testing, then introduces the composition of distributed test system in detail. In order to solve the problem caused by poor flexibility of wired transmission, a wireless distributed testing system based on WLAN is proposed. The construction of the test system is studied, and the network topology is selected. Then, the design of the test node is introduced, including the selection of wireless module and the design of interface circuit. The test performance and wireless transmission performance of the test node are tested. By studying the relevant theory of WLAN networking, the wireless link loss, coverage mode, address allocation and so on are studied, and then the relevant wireless devices are selected according to the project requirements. A wireless distributed testing system based on WLAN network is built. Finally, the correlation performance of wireless network, such as coverage angle, transmission rate and so on, is tested through experiments. The experimental results show that the system has good reliability and stability and meets the requirements of the subject completely. It has an important application value for the field signal testing in the harsh environment.
