摘要:

成像光机部件采用了许多全新的技术,研发测控系统以考核、测量与评估其各项性能指标也是重要课题,加之传统测控系统多是各型号自成一套,不能通用,在这种需求下,研发了具有系统化和通用化的测控平台；该测控平台按照通用化的设计思想,硬件部分设计了通用调理适配单元,对光机部件输出的信号进行统一调理适配,使信号具备标准的电气接口和物理接口,从而与通用集成板卡相连进行数据采集；软件部分设计了底层、逻辑层、表现层的层次结构,对于不同产品仅对表现层进行重新搭建而不需要修改底层和逻辑层；系统在实际应用中,图像和数据采集稳定,采样速率和精度高,实时性好,测控软件层次明确,数据吞吐量大,功能和性能满足多型光机部件的测控要求；该测控平台解决了成像光机部件的测试评估问题和测控系统的通用化问题,具有通用性和可扩展性强的特点。

Abstract:

The image-forming optic-mechanical device has used more new technology, the evaluation and test of which is also an important subject, and conventional test system is always adapted on itself and hasn’t general purpose. Under this background, the universal testing platform of optic-mechanical device is designed. According to universal design method, a signal processing unit is designed in hardware of the platform which transforms the output signals of optic-mechanical device into standard electrical and physical interface, and makes the signals can be acquired directly by universal integrated cards. Software of the platform is designed as hierarchical structure of base level, logical level and display level, and for different model of device only the display level need readjustment. The platform has already satisfied test demands of multi-mode optic-mechanical devices and provided good performance on stability of acquisition, real time character, sampling rate and precision, and the software of the platform has brevity structure and high handling data. The problem of test of image-forming optic-mechanical device and the universal requirement is solved by this method, which has good performance commonality and extensibility.
