【摘要】 为了解决移动通信直放站在研发、生产和入网检测过程中繁琐而不安全的手动测试，和提高直放站的调测效率，本课题的目标是设计基于GPIB虚拟仪器的直放站自动测试系统。本自动测试系统的设计参考了当前国内外主流直放站厂家和检测机构的测试平台，满足Sunwave公司的GSM、CDMA、DCS、WCDMA制式各类型直放站的自动测试、参数设置、故障诊断和报表分析功能。本自动测试系统采用虚拟仪器技术GPIB(IEEE488.2)接口总线连接各信号源、测试仪器和射频开关箱，采用RS232接口查询与设置直放站，以计算机“软件为核心”控制被测直放站和测试仪器协调工作。该项目的创新技术极大地提高了直放站的测试效率和仪器的使用率。在设计过程中，测试流程充分考虑了相关行业标准，按照2006年中国移动集中采购标准协议。在直放站内，采用Philips LPC2212 ARM7内核的单片机设计主控CPU完成数据采集与监控。在带GPIB接口的可程控射频开关系统箱的设计中，采用Intel8051单片机实现开关系统的控制，采用Intel8291A和8292做GPIB接口控制芯片。采用Borland C++编写自动测试系统软件，调用标准PNP VISA函数实现对各类信号源和测试仪器的控制与读数。采用OLE方法将测试报告直接输出到Word文档中，为电子化办公提供了方便。经过Sunwave公司实验测试结果表明，本直放站自动测试系统的性能良好，达到了预期的设计目标。更多还原

【Abstract】 To solve fussy and unsafe manual test of mobile communication repeaters when repeaters are tested by R&D, manufacturing and network access licensing, and to improve efficiency of repeater test, we design a repeater automated test system base on GPIB interface bus Virtual Instrument. The automatic test system design according as currently automatic test system of domestic and foreign repeater leading provider and detecting organization, the automatic test system can test, config, diagnose and report automatically Sunwave each type of GSM, CDMA, DCS and WCDMA repeaters.In the test system, computer links signal generator, test instrument and RF switch by GPIB (IEEE488.2) interface bus with virtual instrument technology, computer config repeater by RS232 interface bus, computer with test software control repeater and all instruments to work following the prescribed order. Innovative technology of the repeater automatic test system will improve greatly repeaters test efficiency and utilization rate of instruments.We analyze fully interrelated industry standard to design process of automatic test. We use Philips LPC2212 ARM7 SCM as CPU for status monitor and Data AcQuisition in repeater, according as repeaters standard protocol of China Mobile central purchase in 2006. lntel8051 SCM is used to control RF switch system, lntel8291A and 8292 are used as GPIB interface control chip in programmable RF switch system case. The automatic system program software is written by Borland C++, computer call PNP VISA standard commands to control or read each signal generator and test instruments. Test report forms are output Word document by OLE for electronic office business expediently.The repeater automatic test system has excellent performance, and meets the goal of the design after Sunwave experiment in factory.更多还原
