Description

technical field [0001] The invention relates to the field of thermal imaging technology development based on focal plane infrared sensor devices, in particular to a method and system for developing infrared focal plane equipment supporting model-based design. Background technique [0002] Thermal imaging equipment based on focal plane infrared sensor devices has continued to expand its application fields since its birth at the end of the last century. From the initial defense and electric power fields, it is gradually expanding to medical, security, chemical, electronics and many other industries. However, with the continuous expansion of its application scope, unknown problems in new fields continue to emerge, the complexity of problems continues to escalate, and the requirements for intelligent applications continue to increase, resulting in increasing special requirements and characteristic constraints for thermal imaging equipment. At the same time, specific solutions fo...

AI Technical Summary

Problems solved by technology

At the same time, specific solutions for specific problems are often individualized and cannot be mass-produced, which also makes it increasingly difficult for R&D institutions to balance the contradiction between R&D costs and market price competition

At the same time, infrared thermal imaging technology, as a way of visually perceiving the surrounding world outside the visible spectrum, has a great demand for future intelligent manufacturing and smart city applications. However, as all technologies facing the development of "Industry 4.0" Like the problem, modern infrared thermal imaging systems are becoming more and more complex and difficult to develop

[0005] 1) The model-based design method represents the research and development trend of complex intelligent system technology in the future. However, due to the characteristics of the combination of optics, thermodynamics and electronic technology, the interface configuration of the focal plane sensor is complex, and it is restricted by embedded hardware technology. There are many obstacles in the simulation method of collaborative development of infrared focal plane equipment based on model design, which greatly restricts the promotion and application of this technology

[0006] 2) Existing model-based development systems or platforms for data acquisition or video applications (such as products launched by NI and Nutaq) only support data links conforming to common protocols and the integration of automatic code generation processes, and are seriously lacking in infrared focus The ability to analyze key parameters of planar equipment (such as NETD, MTF, etc.) and the ability to monitor the temperature measurement and calibration process of equipment

[0007] 3) At present, the relationship between developers and simulation test target resources can only be limited to local resources, and it is impossible to implement distributed development and efficient sharing of team resources, which seriously restricts the development of collaborative development capabilities of R&D organizations. At the same time, due to the types of design files There are many and scattered storage, which makes the management of technical status very difficult

[0008] 4) The existing model-based design technology still lacks a basic model library suitable for supporting the development of infrared focal plane equipment and a corresponding configuration method that can support multiple hardware platforms, which seriously limits the ability of model-based development in the development of infrared focal plane equipment. field of play
