【摘要】：自动测试技术,是一种综合应用技术,该技术包含了控制论,计算机,信息学,数学,电子学等等,是多学科知识结合的体现,从某一程度上说,也是一个国家工业水平的体现。伴随自动测试技术而生的自动测试设备一般包括计算机控制,数据采集设备,数据存储设备,数据处理设备,以及相关的设备连接等。采用自动测试技术的自动测试设备,在已编程序的控制下,能自动或者极少人工参与地进行被测物的测试,这将极大地提高劳动效率以及测试的准确性,安全性等等。本论文中的自动测试设备主要维护对象是飞机机载的电气和电子设备,对这些设备进行测试和故障定位等。本论文立足于飞机的飞控系统,针对上述问题,利用自动测试技术,采用软硬件结合方式,为用户研发了一款自动测试设备,解决了用户的需要。主要内容为:1、研发组建了自动测试平台。测试平台框架由多个独立防震的加固组装箱构成,平台的设备分别安装在组装箱中,各设备之间通过相关电缆进行连接。在平台中,大量使用了GPIB设备,VXI设备以及一些非标设备,满足了测试需要,有效地完成了测试任务。2、设计制造了配套的接口适配器。因为需要测试的设备种类繁杂,设备信号更是错综复杂,需要专门设计适配器将被测成品与自动测试平台连接起来,实现被测成品从激励到信号采集的过程。接口适配器,按照标准设计制造,将测试平台所需资源引入接口适配器前面板,方便被测成品使用。并且接口适配器能很好地安装测试平台上,并能方便地取下,这为我们做不同的测试提供了便利条件。3、开发了各被测成品的测试程序(TP)。在测试中,每个被测成品所需资源不同,测试方法也不同,需要编写不同的测试程序对应不同的需要。测试程序的研发使用,是自动测试中的关键步骤,它将使整个测试按照预想结果顺利运行,达到省时省力的目的。4、研发了自动测试设备自检功能。自检分为上电自检测和维护自检测,上电自检测是每次系统开机时完成,也可以在系统菜单中选择执行,维护自检测主要是在一定使用周期后执行或当系统出现故障需要排故时进行。该自动测试设备在用户使用中,反馈良好,多次为用户进行了成品故障定位,使产品得到及时维修,有力保障了飞机飞行安全。
[Abstract]:Automatic testing technology is a kind of comprehensive application technology, which includes cybernetics, computer, informatics, mathematics, electronics and so on. It is the embodiment of the combination of multidisciplinary knowledge, to a certain extent, It is also the embodiment of a country's industrial level. The automatic test equipment which is accompanied by the automatic test technology generally includes computer control, data acquisition equipment, data storage device, data processing device, and related equipment connection. Under the control of programmed program, the automatic test equipment using automatic test technology can test the object automatically or manually, which will greatly improve the labor efficiency, the accuracy and safety of the test, and so on. The main maintenance objects of the automatic test equipment in this paper are the electrical and electronic equipment on board. This paper is based on the flight control system of the aircraft, aiming at the above problems, using the automatic test technology, using the combination of software and hardware, developed an automatic test equipment for the user, to solve the needs of the user. The main content is: 1, the research and development set up the automatic test platform. The test platform frame is composed of several independent shockproof reinforced and assembled boxes. The equipment of the platform is installed in the assembly box respectively, and each equipment is connected by related cables. In the platform, GPIb equipment and VXI equipment and some non-standard equipments are used in large quantities, which meet the test needs, accomplish the test task. 2 effectively, and design and manufacture the matching interface adapter. Because of the variety of equipment to be tested and the complexity of the equipment signal, it is necessary to design a special adapter to connect the finished product under test and the automatic test platform to realize the process from excitation to signal acquisition. The interface adapter is designed and manufactured according to the standard. The resource of the test platform is introduced into the front panel of the interface adapter to facilitate the use of the finished product under test. And the interface adapter can install the test platform very well and can be removed conveniently. This provides convenient conditions for us to do different tests. The test program of each finished product is developed. In the test, each finished product needs different resources and different testing methods. The research and application of test program is the key step in automatic test. It will make the whole test run smoothly according to the expected results and achieve the purpose of saving time and effort. Self-test is divided into power-on self-detection and maintenance self-detection. Power-on self-detection is completed every time the system is turned on, and it can also be selected and executed in the system menu. Maintenance self-detection is mainly performed after a certain period of service or when system failure needs to be eliminated. The automatic test equipment has good feedback in the use of the user, and the product fault location has been carried out for the user many times, so that the product can be repaired in time, and the flight safety of the aircraft can be guaranteed.
