This dissertation lucubrates the architecture of ATS, hierarchical structure and resource models of testing software and the physical structure of hardware.

主要成果是：（1）研究了 ATS 执行机制，首次提出了基于虚拟仪器测试引擎的开放式 ATS 体系结构，从根本上实现了 ATS 硬件无关性和测试代码重用性；（2）研究了采用 IVI、IVI-MSS 和组件技术实现 ATS 仪器互换性的技术与方法，对实现 ATS 网络化奠定了基础；（3）研究开发了测试流程描述语言及相关仪器描述模型、开关矩阵描述模型、测试适配器描述模型，实现了测试软件的结构化和模块化，使大型复杂武器装备测试系统的开发与维护效率大大提高；（4）研究了与 ATS 体系结构相适应的硬件物理结构，该结构实现了 ATS 的通用性、开放性和可扩展性。

In the design of the software and communication network, the concept of TTCAN makes CAN communication more soft and rhythmical. Moreover, the real-time communication between the control network for field device and information network is completely realized by Internet. As a result, the campus electricity consumption can be remotely detected, reliably monitored, and safely maintained in real-time.

通信网络及软件上采用TTCAN概念对CAN网络进行有序化，建立TTCAN通讯机制，进而通过转换接口接入Internet，实现控制网络与信息网络实时通信，便于安全、实时、可靠地实现远程监控、诊断和维护校园用电。

The software, including machine diagnostic capabilities, allows precise monitoring of most of the operating and maintenance data.

When they do have coordinators and eager students who troubleshoot problems and do the repairs, there are still software glitches and servers that crash, torpedoing lessons again and again.

即便这些学校中却有计算机维护人员与一些热心的学生帮助解决麻烦，维修机器，到处依旧能够见到软件崩溃与服务器当机，一次又一次地耽误原定授课计划。

So the technique of uncooled microbolometer infrared imaging has become one of the main points from now on. In the paper uncooled microbolometer infrared imaging system is studied from focal plane character, image dealing and application. The details are in the following: On uncooled microbolometer infrared focal plane aspect: first, the work principle of microbolometer, manufacturing technology of microbolometer infrared focal plane, temperature balance equation of microbolometer detector are analyzed. The performance of microbolometer detector is predicted by model. Second, the infrared focal plane is the core of infrared system, whose quality can determine the performance of the system. It is the precondition that the high quality of every detective unit maintains the qualification of the focal plane. The even degree of detective units has great influence on imaging characters if the other characters of detective units are normal.

本文以非致冷微测辐射热计红外成像系统为对象，从焦平面特性、图像处理和红外系统应用方面展开分析、研究，具体内容如下；在微测辐射热计红外焦平面方面，首先分析了微测辐射热计的工作原理、微测辐射热计红外焦平面的工艺制作、微测辐射热计探测单元的温度平衡方程，根据有关参数对其特性进行建模预测；其次，红外焦平面是红外系统的核心，它的质量的好坏直接决定系统性能，因此保证其各探测单元的高性能是维护焦平面品质的前提，在探测单元其它特性正常的情况下，各探测单元之间特性的均匀程度对系统成像性能有极大影响，为此本文提出自适应滤波多项式焦平面非均匀性校正算法从软件角度解决焦平面的固有的噪声问题。
