Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] The present invention utilizes the interference of human's daily behavior on the signal within the wireless signal coverage range, uses general wireless equipment to collect signal data, uses signal processing and machine learning methods, and provides real-time behavior prediction through the pre-trained prediction model As a result, in order to achieve the purpose of human behavior recognition. The recognition results can be used in the care of the elderly, behavior monitoring in specific areas, and other places.

[0049] figure 1 It is a system structure diagram of the present invention, wherein only two signal receivers are listed in the diagram, which can be expanded as required in practical applications. The system includes a behavior recognition system server 104, which is mainly responsible for data preprocessing, spectrum analysis and ...

Abstract

The invention discloses a behavior identification system based on wireless signal identity. The system comprises an identification system server, one or more signal receivers, a signal emitter and a user terminal. According to the system, more devices can be adaptively added for acquiring signal intensity indications at the same time in a convenient way, and the reliability and the coverage scope of the system are further improved. The invention further discloses a behavior identification method based on wireless signal identity. According to the method, all processing flows are concentrated at the identification system server, the functions of the signal receivers are more simplified, and what is needed is only to acquire signals and send the signals to the identification system server, such that the physical performance requirements of the receivers can be reduced, the volume of the receivers is smaller, the price is low, the cost of the whole system is decreased, and at the same time, the disposition is quite convenient.

Description

technical field [0001] The invention belongs to the field of wireless network and behavior recognition, in particular to a system and method for human behavior recognition based on wireless signal strength. Background technique [0002] In the field of behavior recognition, the recognition and detection of human behavior plays a very important role in medical and monitoring systems. In the medical field, the detection of human fall behavior can monitor the dangerous behavior of the elderly or children and issue early warnings to avoid accidents. At the same time, in the field of monitoring, real-time human behavior detection can detect the behavior of individuals within the coverage of the wireless network, and the detection results can be fed back to users in real time. In this way, users can receive all behaviors within the monitoring range in real time to achieve the purpose of monitoring security. Since the wireless signal has the characteristics of electromagnetic wav...
