State detection system

A state detection system is provided with: a sensor (10) which has an electromagnetic wave reflecting material (13) and a resonator (11) disposed adjacent to or integrally with the electromagnetic wave reflecting material (13), and which detects a change in the state of a surrounding object or surrounding environment as a change in the electromagnetic wave reflection characteristics of the sensor (10); a reader (20) that transmits electromagnetic waves to the sensor (10), receives reflected waves thereof, and acquires reflected spectrum information of the sensor (10); and an analysis device (30) that estimates the state of the detection target of the sensor (10) at the current point in time by applying reflected wave intensity information at a plurality of frequency positions of the reflected spectrum information to a learning model (30D) generated in advance from teacher data of the reflected spectrum for each state of the sensor (10). 一种状态检测系统，具备：传感器(10)，具有电磁波反射材料(13)以及与该电磁波反射材料(13)邻接地或者一体地配设的共振器(11)，将周围物体或
