Embodiment Construction

[0071] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0072] Such as figure 1 As shown, a positioning method of an indoor Internet of Things active tag includes the following steps:

[0073] S1. Multiple readers are used to respectively read the signal strengths of active tags of the Internet of Things.

[0074] S2. Summarize the signal strength data read by multiple readers to the central processing unit:

[0075] Such as figure 2 As shown, the central processing unit communicates with each reader through the TCP protocol Socket socket, collects the data of each reader, and the data is encapsulated by bit, including the ID of the reader, and the information of the reader receiving the active tag of the Internet of Things. Signal strength and timestamp of received message.

[0076] S3. The central processing unit initially screens and groups the signal strength data:

[0077] The central pro...

Abstract

The present invention provides an indoor Internet of things active tag location method. The method comprises: performing preliminary screening and grouping of signal intensity data of the Internet of things active tags received by each reader; calculating the initial coordinates of the Internet of things active tags according to grouping data; and performing iteration correction of the initial coordinates of the Internet of things active tags, and obtaining finial coordinates of the Internet of things active tags. The indoor Internet of things active tag location method performs calculation and iteration of the signal intensity of the Internet of things active tags collected by a plurality of readers installed indoors to realize the three-dimensional location of the indoor positions of the Internet of things active tags with no need for human intervention, and is high in location precision and rapid in speed.

Description

technical field [0001] The invention relates to the technical field of radio frequency positioning of the Internet of Things, in particular to a positioning method for an active tag of the Internet of Things indoors. Background technique [0002] At present, the positioning error of the active tags of the Internet of Things is relatively large under the conditions of the computer room, and it is impossible to achieve accurate and effective three-dimensional positioning. Indoor IoT radio frequency positioning technology has extremely important value in the field of equipment management. It is very necessary to realize a reliable, efficient and accurate positioning method to meet the requirements of practical applications. Contents of the invention [0003] The purpose of the present invention is to provide a positioning method for the active tags of the Internet of Things indoors. According to the signal strength of the active tags of the Internet of Things collected by mul...
