Development Of Multi-channel Test Data Recorder

Infrared seeker is an important component of the missile as the positioning device. The experimental work of infrared seeker is significant to the development of the missile. To make the data recording device for the infrared seeker, which is remote from operator and needs many tests, is of important practical significance and application value. This paper develops the recorder of infrared seeker test data to save the original experiment data and transfer the data to PC through LAN interface for data analysis and process, which helps to improve the experiment of infrared seeker.Based on the full analysis of the technical measurement parameters, the paper proposes the design and complete the hardware and software work. In hardware design, this paper choose FPGA as the main control chip, capture and stare the multi-channel LVDS signals and 13 road slowly varying analog signals through dedicated chips. This paper transmit the data as TCP protocols to realize transmission to PC from the recorder, which makes use of Lab Windows/CVI to implement the function of data analysis and image data recovery in the software design. The interface is concision and intuitionistic, which makes the operation easy and direct to analyze for the operators.The experiment results show that the module hardware is reliable while the design is reasonable, and the test data recorder can be delivered.
