模拟人体系统中生命信号发生器的研究

Study on life signal generator in simulated human system

介绍模拟人体系统在雷达式非接触生命探测中的作用和意义,同时针对雷达式非接触生命探测的特点,提出了模拟人体系统中生命信号发生器所需的人体呼吸和心跳的信号标准,并使用一次性可编程语音芯片AP8821设计该信号发生器,所产生的信号为整个系统后级设计提供了精确可调的信号源。

This paper briefly presents the effect and significances of simulated human system for non-contact life-detecting based on radar mode. Aiming at peculiarities of radar non-contact life-detecting, it puts forward the signal standards of human respiration and heartbeat which are needed by the life signal generator in simulated human system. The signal generator is designed on the basis of one time programmed voice chip AP8821. Signals from the generator provide exact and adjustable source for subsequent designs of the whole system.
