Rotating scanning type wear-free indoor positioning device and method

Abstract

The present invention discloses a rotating scanning type wear-free indoor positioning device and a method. The positioning device comprises a motor, a motor driving circuit bottom board, a fixed frame, a stator, a rotor, a circuit board and a thermopile sensing probe. The motor driving circuit bottom board is electrically connected to the circuit board through a line, the stator, and the rotor. The circuit board is electrically connected to the thermopile sensing probe. The motor drives the circuit board through the rotor, and the circuit board drives the thermopile sensing probe to rotate. According to the rotating scanning type wear-free indoor positioning device and the method, the problems of low resolution and narrow sensing range of a linear array sensor and the high price of a high-resulotion area array sensor are solved, the contradiction problem of a resolution and a range of sensing is solved, a method of rotating scanning is employed, the effect of the high-resulotion area array sensor is realized by using the linear array sensor with low cost is obtained, and the sensing range of a sensor is expanded.

Description

technical field [0001] The invention relates to a device and method for locating a human body target. Background technique [0002] Existing target positioning methods are divided into wearable positioning methods and wear-free positioning methods according to whether they need to carry a positioning device. The essence of the wearable positioning method is to locate the device carried by the target, such as GPS positioning, ultrasonic positioning, and Bluetooth positioning. , WIFI or Zigbee based on RSSI positioning, UWB positioning, etc. In the wear-free positioning method, the target does not need to carry any device, such as computer vision positioning and pyroelectric infrared positioning. [0003] Disadvantages / deficiencies of existing technologies: [0004] Wearable positioning method: Based on the positioning scheme of wearable bracelets or watches, there are problems such as long-term carrying discomfort, regular charging, and long-term close use may have electrom...

AI Technical Summary

Problems solved by technology

[0004] Wearable positioning method: Based on the positioning scheme of wearable bracelets or watches, there are problems such as long-term carrying discomfort, regular charging, and long-term close use may have electromagnetic radiation that may affect health.

[0005] Video surveillance method: The video (image) analysis and extraction of human targets realized by ordinary optical cameras has problems such as being greatly affected by light, complicated algorithms, and infringing on the privacy of the measured targets.
