Human body existence detection system based on wireless signal

Abstract

The invention proposes a human body existence detection system based on a wireless signal. The system comprises a main unit device and slave unit devices. The main unit device has the capability of wireless signal transmitting and receiving, and performs the data communication with the slave unit devices, and is connected to the Internet in a wired mode or a wireless mode. The slave unit devices perform the networking and data communication with the main unit device in a wireless mode. The main unit device and one or more slave unit devices form a wireless local area network. A user can checkthe wireless signal intensity of different slave unit devices through the main unit device. through the change comparison of wireless signal intensities between the main unit device and the slave unitdevices under the condition that there is no person in a current region and there is a person in the current region, the system judges whether there is a current region or not.

Description

【Technical field】 [0001] The invention relates to the field of smart home technology, in particular to a method for detecting the presence of an indoor human body based on a wireless signal. The presence detection of the human body, and then realize the induction control of the smart home system. 【Background technique】 [0002] "When people come, the lights are on, and when people leave, the lights are off". This is the most basic requirement for smart homes and smart lighting. The existing human body movement detection technology mainly uses pyroelectric infrared detection technology. The biggest disadvantage of this detection method is that it cannot detect static The human body, such as bedrooms, bathrooms, offices and other occasions, is not suitable, and it is also easily affected by the temperature of the external environment. However, the latest improvement scheme uses infrared arrays to detect the existence of human bodies. Although it can detect stationary human bo...

[0002] "When people come, the lights are on, and when people leave, the lights are off". This is the most basic requirement for smart homes and smart lighting. The existing human body movement detection technology mainly uses pyroelectric infrared detection technology. The biggest disadvantage of this detection method is that it cannot detect static The human body, such as bedrooms, bathrooms, offices, etc. is not suitable, and it is also easily affected by the temperature of the external environment

The latest improvement scheme uses infrared arrays to detect the existence of human bodies. Although it can detect stationary human bodies, it has the disadvantages of small detection range and high cost.
