【摘要】：綜合通信系統(tǒng)由主控設備、轉接設備及多個終端設備組成，設備之間通過有線電纜相連。該系統(tǒng)接口數(shù)量繁多，主要分為串口、電臺口及二線口三類。接口的有效性是整個系統(tǒng)正常工作的基礎，保障接口有效性的重要手段是檢測和測試。 然而，現(xiàn)存的測試設備并不能很好地解決接口檢測的問題。目前，對接口的檢測主要采用傳統(tǒng)測試儀器進行人工測試，測試手段單一，且傳統(tǒng)儀器使用繁瑣，對測試人員專業(yè)要求較高，檢測周期長，不能快速大量地對接口進行檢測。 為此，本文設計并開發(fā)了接口測試儀軟件，針對綜合通信系統(tǒng)設計接口測試方案，以幀數(shù)據(jù)報文測試的方式判斷設備是否正常工作，若異常，則通過電壓、電流、波形及頻譜檢查被測設備的板卡，定位故障板卡，實現(xiàn)快速修復。本文所做主要工作如下： 第一，分析被測設備接口報文及信號，提出接口測試儀的功能需求和性能指標，，基于OMAP3530平臺劃分接口測試儀的軟件層次及結構，設計系統(tǒng)各個單元間的通信協(xié)議，并規(guī)定單元間通信實現(xiàn)方式。 第二，分析接口測試儀的關鍵技術，設計報文處理算法及信號處理算法。采用幀數(shù)據(jù)測試思想對被測設備報文收發(fā)能力進行測試，采用高速DSP實現(xiàn)波形數(shù)據(jù)的去抖、濾波及參數(shù)計算。 第三，整合圖像界面單元和系統(tǒng)控制單元，建立程序完善的配置機制和控制機制，簡化操作流程，達到對接口測試儀控制管理的目的。 第四，通過實際測試及模擬測試兩種測試方式對接口測試儀的功能進行測試，保證接口測試儀工作的有效性及可靠性。 本文針對綜合通信系統(tǒng)中的接口設計并開發(fā)了接口測試儀軟件，將幀數(shù)據(jù)測試功能與示波器功能集成在一臺便攜式小型設備上。通過接口測試儀，能夠快速有效地對該通信系統(tǒng)中的接口進行日常檢測和維護，簡化了接口測試的繁瑣工作，具有良好的軍用價值，現(xiàn)已投入使用。
[Abstract]:The integrated communication system is composed of main control equipment, switching equipment and several terminal equipment, and the equipment is connected by wired cable. The system has a large number of interfaces, mainly divided into serial port, radio port and second port three categories. The effectiveness of the interface is the basis of the normal work of the whole system, and the important means to ensure the effectiveness of the interface is to detect and test. However, the existing test equipment can not solve the problem of interface detection. At present, the traditional testing instruments are mainly used for manual testing of the interface, the test means are single, and the use of the traditional instruments is tedious, the professional requirements of the testers are high, the detection cycle is long, and the interface can not be detected quickly and extensively. For this reason, this paper designs and develops the interface tester software, designs the interface test scheme for the integrated communication system, and judges whether the equipment is working properly by frame data message test. If it is abnormal, it passes through voltage and current. The waveform and spectrum check the board of the equipment under test, locate the fault card, and realize the rapid repair. The main work of this paper is as follows: first, the interface message and signal of the tested equipment are analyzed, the functional requirements and performance indexes of the interface tester are put forward, and the software hierarchy and structure of the interface tester are divided based on OMAP3530 platform. The communication protocol between each unit of the system is designed, and the realization mode of communication between units is stipulated. Secondly, the key technology of interface tester is analyzed, and the message processing algorithm and signal processing algorithm are designed. The frame data test idea is used to test the message receiving and receiving ability of the equipment under test, and the high speed DSP is used to realize the de-shaking of waveform data and the calculation of filtering and parameters. Thirdly, the image interface unit and the system control unit are integrated, the configuration mechanism and control mechanism of the program are established, the operation flow is simplified, and the purpose of control and management of the interface tester is achieved. Fourth, the function of the interface tester is tested by practical test and simulation test, so as to ensure the effectiveness and reliability of the interface tester. In this paper, the interface tester software is designed and developed for the interface of integrated communication system. The frame data test function and oscilloscope function are integrated into a portable small device. Through the interface tester, the interface in the communication system can be detected and maintained quickly and effectively, which simplifies the tedious work of interface testing and has good military value, and has been put into use.
