HUMAN DETECTION DEVICE AND HUMAN DETECTION METHOD

PROBLEM TO BE SOLVED: To provide a human detection device and a human detection method having higher reliability. SOLUTION: A master machine 11 transmits a signal from an antenna 102. A detection part 202 of a slave unit 12 converts the signal into a voltage, and an A/D conversion part 203 digitizes the voltage. A signal transmission part 204 generates a signal indicating a voltage value acquired by digitization, and transmits it from an antenna 201. An operation part 104 of the master machine 11 calculates a value Vd indicating a change with time of a voltage indicated by the signal. A determination part 106 reads out a threshold Vth from a threshold storage part 105, and determines whether the value Vd exceeds the threshold Vth. When determined that the value Vd exceeds the threshold Vth, a detection signal transmission part 107 transmits a detection signal indicating that a human is detected to a communication network 2.
