【摘要】：自动测试平台结构简单，体型小，成本低，用自动测试平台代替人工测试手段，可以使得产品研发和测试具有更高效的测试速度、更准确的数据记录、对产品的功能测试针对性强，对产品的稳定性测试、压力测试更具有全面性。同时，自动测试设备与传统测试设备相比，具有功能齐全、操作简单方便、测试准确度高、可面对面操作、可远程测试操作和批量化测试等特点。本论文针对一款开关机自动化测试平台的设计与实现，，本论文的开关机自动化测试平台分为两个部分组成，分别是电源控制部分和自动控制部分，并分别对两个部分的原理设计，器件选型，硬件设计做了阐述，并在硬件完成后进行了充分测试，验证该平台是否完成了设计需求，达到设计目的。主要内容为： 1．首先详细分析了系统设计需求，通过需求描述了该自动化测试平台的硬件架构应分为两个部分电源控制部分和自动控制部分，进一步描述了两个部分的设计原理，并在设计原理的基础上，参考各种设计思路最终进行器件选型。 2.开关机自动化测试平台的设计实现，该平台使用嵌入式模块作为自动控制核心部分，并在其基础上增添多种测试端口以完善其测试功能。该测试平台支持直接操作，使用者可以通过测试平台的显示接口和鼠标、键盘口进入系统，并在系统内设置测试模式，进行直接操作测试；如果使用者觉得连接显示器太笨重还可以通过测试平台的液晶显示板和前面板上的控制按钮直接设置测试模式；如果使用者当时不在测试平台周边，该测试平台还支持网络远程操作，使用者在远端随意找一台电脑通过远程登录进入测试平台的控制界面。因此该平台有着操作多样性的特点。 3.开关机自动化测试平台实际完成后，必须根据设计需求，验证是否达到设计初期的预想，因此需要对该平台做测试验证，测试方法有板卡测试，整机测试，功能测试，性能测试，可靠性测试。并在这众多测试中找出问题，解决问题，最终完成该平台的实现。最后该平台已通过实践测试，验证了设计思路的正确性，达到了预期要求。该自动测试平台支持的多种人性化使用模式大大扩展了其应用范围。
[Abstract]:The automatic test platform is simple in structure, small in size and low in cost. Using automatic test platform instead of manual test means can make the product development and test have more efficient test speed and more accurate data record. The function test of the product has strong pertinence, the stability test and the stress test of the product are more comprehensive. At the same time, compared with the traditional test equipment, the automatic test equipment has the characteristics of complete function, simple and convenient operation, high testing accuracy, face to face operation, remote test operation and batch testing. This paper aims at the design and realization of an automatic test platform for switch machine. The automatic test platform of switch machine is composed of two parts: power control part and automatic control part. The principle design, device selection and hardware design of the two parts are described, and after the completion of the hardware, a full test is carried out to verify whether the platform has completed the design requirements and achieve the design purpose. The main contents are as follows: 1. Firstly, the system design requirements are analyzed in detail, and the hardware architecture of the automatic test platform is described through the requirements, which should be divided into two parts: power supply control part and automatic control part. The design principle of the two parts is further described, and based on the design principle, the device selection is carried out with reference to various design ideas. 2. The automatic test platform of switch machine is designed and implemented. The embedded module is used as the core part of automatic control, and a variety of test ports are added to the platform to improve its testing function. The test platform supports direct operation, and the user can enter the system through the display interface, mouse and keyboard port of the test platform, and set up the test mode in the system for direct operation test. If the user feels that the display is too cumbersome to connect, the test mode can be set directly through the LCD panel of the test platform and the control button on the front panel; If the user is not around the test platform at that time, the test platform also supports the remote operation of the network. The user can easily find a computer in the remote end to enter the control interface of the test platform through remote login. Therefore, the platform has the characteristics of diversity of operation. 3. After the actual completion of the automatic test platform of switch machine, it must be verified according to the design requirements, whether or not to meet the initial design expectations, so the platform needs to be tested and verified. The test methods include card test, whole machine test, function test, etc. Performance test, reliability test. And in the numerous tests to find out the problem, solve the problem, and finally complete the implementation of the platform. Finally, the platform has been tested in practice to verify the correctness of the design idea and meet the expected requirements. This automatic test platform supports a variety of humanized usage patterns, which greatly extend its application range.
