【摘要】：伺服系统测试平台是在进行伺服系统各项地面测试试验的过程中使用的非标地面测试设备。由于其是保障各个类军工产品的研制进度,批产速度以及装备进度的重要设备,其对国防建设,保障国家安全都有重要意义。由于测试平台是通过各个对外接口实现与伺服系统间的数据传输以及采集伺服系统外部传感器数据的功能。因此,一般的测试设备都需要根据不同类型的伺服系统进行定制设计,不仅生产设计周期长,而且在出现技术问题时更改维护麻烦。导致由于测试设备影响伺服系统交付进度,进而影响整个项目研制进度的情况屡屡发生。本论文的研究目的是以搭载1553B总线、CAN总线和模拟输入输出板卡的PCI平台工控机为核心,设计一套价格便宜且功能强大的伺服系统综合仿真测试平台。设计完成后的测试平台不仅能够满足多个型号伺服系统测试试验的使用,还由于在设计时引入通用化设计理念,减少了未来测试设备的研制周期。本文首先介绍了伺服系统测试平台的分类和工作原理。之后,分析了任务书需求,设计了包括线性电源,电压电流传感器,模拟信号隔离模块以及全屏蔽的测试转接箱和电缆网组成的配套硬件系统。同时,为了满足数字总线精确定时,数模同步触发以及高速模拟信号采集处理的测试精度要求,开发了包含1553B双缓冲消息队列,虚拟硬件时钟定时,同步触发以及高速模拟数据处理功能的测试平台软件。最后,介绍了对测试平台进行各项检定测试、仿真测试及实验验证的方法和验证测试结果。验证测试结果表明,测试平台的设计与生产都符合预期的设计技术指标。其不仅具有高效精确的采集测试功能,而且操作简洁方便,提高了伺服系统的生产速度。
[Abstract]:The servo system test platform is a non-standard ground test equipment used in the ground test of servo system. Because it is an important equipment to guarantee the development progress, batch production speed and equipment progress of various kinds of military products, it is of great significance to national defense construction and national security. Because the test platform realizes the data transmission between the servo system and the servo system through each external interface and the function of collecting the external sensor data of the servo system. Therefore, the general test equipment needs to be customized according to different types of servo system. It not only has a long production design period, but also changes the maintenance trouble when technical problems occur. As a result of the test equipment affecting the servo system delivery progress, and then affect the development of the whole project often occurs. The purpose of this paper is to design a cheap and powerful integrated simulation and testing platform of servo system based on PCI platform industrial control computer with 1553B bus, CAN bus and analog input and output board. After the design, the test platform can not only meet the test of multiple models of servo system, but also reduce the development period of the future test equipment because of the introduction of the general design concept in the design. This paper first introduces the classification and working principle of servo system test platform. After that, the requirements of the taskbook are analyzed, and a complete hardware system consisting of linear power supply, voltage and current sensor, analog signal isolation module, fully shielded test transfer box and cable network is designed. At the same time, in order to meet the precision requirements of digital bus precise timing, digital-analog synchronous trigger and high-speed analog signal acquisition and processing, a 1553B double buffer message queue and a virtual hardware clock timing are developed. Test platform software for synchronous trigger and high-speed analog data processing. Finally, the methods and results of verification, simulation and verification of the test platform are introduced. The test results show that the design and production of the test platform are in line with the expected design specifications. It not only has high efficiency and accurate collection and testing function, but also has simple and convenient operation, and improves the production speed of servo system.
