Abstract

The invention provides a method for accurately sensing the presence of indoor personnel. A sensing system and a sensing control management system of a remote end are constructed and started. The sensing system is formed by an infrared sensor probe, a single chip microcomputer and a PTZ motor device. The infrared sensor probe is driven by a PTZ motor and is fixed at an upper part space of one side in a closed space. The single chip microcomputer is used for processing a received signal of the infrared sensor probe, controlling the motor and providing web service. The sensing system is internally provided with a signal processing system, wherein the infrared sensor probe obtains an infrared wave signal in real time, the signal processing system is used for processing the infrared wave signal and forming an infrared heat source feedback value. The sensing control management system of the remote end is started and is used for managing and controlling the operation of the sensing system in the closed space. A sensing monitoring system of the remote end is started and is used for monitoring infrared wave signal data reported by the sensing system in real time.

Description

technical field [0001] The invention belongs to the general technology of the Internet of Things, relates to the field of infrared perception, and specifically relates to a method for accurately sensing the presence status of indoor personnel. Background technique [0002] By using the thermal infrared sensor of the human body to detect the thermal infrared signal within the range, it is possible to perceive whether there is someone within the range; since the human body emits infrared rays with a specific wavelength of about 10 UM, the passive infrared probe relies on detecting the human body to emit It works with infrared rays around 10UM. The infrared rays emitted by the human body around 10 UM are enhanced by the Fischer filter and then gathered on the infrared sensing source. Infrared induction sources usually use pyroelectric elements, which will lose their charge balance when they receive changes in the infrared radiation temperature of the human body, and release ch...
