Embodiment Construction

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] The main solutions of the embodiments of the present invention are:

[0038] Obtain the electromagnetic wave signal strength received by each wireless receiver, wherein the wireless receiver has a corresponding wireless transmitter;

[0039] Determine the distance value of the user from each line according to the signal strength of the electromagnetic wave, wherein the wireless receiver and the wireless transmitter are arranged at both ends of the ground line;

[0040] The location information of the user is determined according to the distance value and the location information of each wireless transmitter and the corresponding wireless receiver.

[0041] Because in the prior art, a device using radio wave positioning has certain requirements on the deployment environment, and the cost is relatively hig...

Abstract

The invention discloses a power line positioning method, and the method comprises the steps: acquiring the signal intensity of an electromagnetic wave signal received by each wireless receiver, wherein each wireless receiver has a corresponding wireless transmitter; determining the distance between a user and each ground line according to the signal intensities of the electromagnetic wave signals,wherein the wireless receivers and the wireless transmitters are respectively disposed at both ends of the corresponding ground line; and determining the location information of the user according tothe distance values and location information of each wireless transmitter and the corresponding wireless receiver. The invention also discloses a power line positioning device and system and a computer storage medium, which realize positioning of the user by using an existing power line and a low-cost wireless transmitter and wireless receiver.

Description

technical field [0001] The present invention relates to the field of positioning technology, and in particular, to a power line positioning method, device, system and computer storage medium. Background technique [0002] With the rapid development of mobile computing and embedded systems, people are increasingly interested in location awareness, so location-based service systems have also received more and more attention. The global positioning system is the most widely used positioning system at present, but when satellite positioning cannot be used in the indoor environment, indoor positioning technology is used as an auxiliary positioning for satellite positioning to solve the problem that satellite signals are weak and cannot penetrate buildings when they reach the ground. Locate the current position of the object. [0003] Nowadays, the more common indoor positioning technologies include infrared positioning, Bluetooth positioning, ultrasonic positioning, wireless loc...
