Biological state acquisition device, biological state acquisition program, device provided with biological state acquisition device, and air conditioner
PROBLEM TO BE SOLVED: To provide a biological state acquisition device, etc. capable of acquiring biological signals of a living body in a noncontact manner and acquiring the information relating to a biological state without applying complicated processing such as frequency analysis to the biological signals.SOLUTION: A biological state acquisition device transmits electromagnetic waves to a body surface of a living body, performs IQ detection of the reflection waves, sequentially acquires an I signal and a Q signal in time series, and acquires a biological state of the living body on the basis of the locus of the acquired signals on an IQ plane. Heart beat detection means 56 included in biological state acquisition means 52 for acquiring a state of a living body extracts a heart beat signal from the time-series data of the norm of the position vector of the acquired signals on the IQ plane, detects a heart beat signal corresponding to one heart beat on the basis of the periodical variation of the waveform of the extracted heart beat signal, calculates the number of heart beats in a unit time period as heart beat information, calculates the number of heart beats in a unit time period over a predetermined period of time to calculate a frequency distribution of the number of heart beats, and determines whether or not the number of heart beats is counted normally on the basis of whether or not the frequency distribution assumes a shape of a nearly normal distribution.
