Method and system of detecting dynamic status of a space

A detecting system for detecting a dynamic status in a space, comprising:

• at least two wireless communication devices, deployed in the space and capable of performing a channel state detection to obtain a channel state information;
• and
• a computing device, comprising:
• a processing unit, configured to execute a program code;
• and
• a storage unit, coupled to the processing unit to store the program code, wherein the program code is configured to instruct the processing unit to execute the following steps:
• controlling the at least two wireless communication devices to perform the channel state detection in a registration stage to obtain a plurality of registration-stage channel state information;
• determining an environmental data of the space according to the plurality of registration-stage channel state information;
• controlling the at least two wireless communication devices to perform the channel state detection in a detection stage to obtain a plurality of detection-stage channel state information;
• and
• determining an intrusion situation of the space according to the environmental data and the plurality of detection-stage channel state information;
• wherein the step of determining the environmental data of the space according to the plurality of registration-stage channel state information comprises:
• using a principal component analysis to convert the plurality of registration-stage channel state information into a plurality of registration-stage principal component data;
• and
• using a deep learning model to select a registration-stage principal component data from the plurality of registration-stage principal component data as the environmental data.
