Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0022] At present, the location-finding solution involves Bluetooth-based device location and management. It mainly uses Bluetooth tags and Bluetooth gateways for positioning and resource device management. The existing method is to use the difference in signal transmission strength between Bluetooth gateways and Bluetooth tags for positioning. , which is based on the RSSI ranging principle for positioning. Due to the complex indoor environment, there will be deviations in the distance calculated based on the RSSI ranging principle. When positioning, use the triangula...

Abstract

The invention discloses a method and device for locating and searching an object in a target area, and relates to the field of the Internet of Things, and the method comprises the steps: obtaining a signal intensity value of a to-be-located label; arranging the to-be-positioned label on the to-be-searched article, wherein the to-be-searched article is used in the target area; comparing the signal intensity value of the to-be-positioned tag with signal intensity values of a plurality of fingerprint tags pre-collected into a fingerprint database through a plurality of gateways to obtain all target fingerprint tags, wherein the signal intensity difference values between the target fingerprint tags and the to-be-positioned tag are smaller than a preset threshold value; taking the signal intensity difference value between each target fingerprint label and the label to be positioned as the weight of each target fingerprint label, and arranging the plurality of fingerprint labels at different positions in the target area; and according to the weight of each target fingerprint tag and the coordinate position of each target fingerprint tag, determining the coordinate position of the to-be-positioned tag, and further determining the position information of the to-be-searched article in the target area. According to the invention, the object can be efficiently and accurately found in the target area.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and device for locating and finding objects in a target area. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, in enterprises, there are often various physical equipment resources. Due to the large number of personnel and complex borrowers of each physical equipment resource, it is impossible to find the corresponding equipment resources in a short time. It is mainly a single resource, including Octopus Fish (dial-dialing equipment needed during the meeting), laptop and other conference equipment. When the user needs to use it, the unified manager cannot find it immediately, which delays working time. Contents of the invention [0004] An emb...
