摘要
提出一种对多路红外脉冲信号进行同步采集的设计方案并给予工程实现;为了提高系统的可靠性,设计中采用FPGA技术解决了采用普通电路实现时布板面积大、元器件数目多、电路复杂且难以同步等问题;该系统具有检测路数多、同步性能好、外部电路简单、成本低廉等优点;实际应用结果表明,该检测系统可靠性高,稳定性强,可扩展性好;不仅可应用于物体红外特性的分析,还可应用于红外图像的采集与处理等其它用途。
A design plan of Muhichannel Infrared Signal＇ s Synchronous Detecting is presented. To improve system＇s dependability, and to solve the problems such as big area, diversiform eomponems, complex circuit and imprecise synchronization, the hardware programmable technology （FPGA） is adopted. System have the property below： numerous detecting channel, good synchronization, brief circuit, low price, and so on. In the end, through applying in the reality, result presents that performance of the system is stable and extensible, which can be used in the field of not only analyzing the object＇s infrared property but searching the gathering and disposal of infrared image.
