Embodiment Construction

[0033] According to the guidance of theoretical research, the 2.4G network will have a relatively large change curve when it is affected by the environment at about 8 meters. Combined with the actual indoor environment of the laboratory and the indoor environment of the parking lot, it is determined that the side length is 6.5 to 7.5 meters in practical applications. The area is the best networking distance. Through the analysis of the indoor environment, choose regular isosceles, equilateral and other regular graphics for network analysis, which can realize the whole network coverage. In addition, the network distribution of the isosceles triangle can not only achieve coverage The efficiency is high, and it can also solve the problem that the triangular centroid algorithm cannot be performed. At the same time, the uniform distribution of multiple sets of reference nodes can be realized during the motion process. Therefore, it is set to form a network with an isosceles right tr...

Abstract

A method for zigbee indoor location networking design and corresponding simplification belongs to the field of network of things. The method includes determining an area with side length being 6.5-7.5 in actual application to be optimum networking space, selecting common isosceles triangle or equilateral triangle to conduct networking and obtaining a value parameter A by offset estimation. The method simplifies a research process and is favorable for raising a corresponding research model. Effective location data can be obtained under a networking plan by value relation only related to a parameter n obtained by reduction by means of the proportional relation of three points and a coordinate value. The method enables a location process to be free of interference of the parameter A and the parameter n and only needs to obtain relative function relation with the parameter n after parameter elimination and known reference point coordinate under the corresponding relation. Therefore, corresponding coordinate is calculated, and the location aim can be achieved. By means of the method, networking density and the networking plan are scientifically designed. The method provides an analysis base for proceeding of a scientific experiment and application cost.

Description

technical field [0001] The invention relates to a network planning and a corresponding simplified algorithm process in the process of indoor positioning. The combination of network planning and algorithm design, through reasonable analysis and design, is within the scope of application of the network. The traditional parameters A and n, which are greatly affected by environmental changes, are transformed into only considering the change characteristics of n, so that the corresponding positioning data can be obtained. He is a major breakthrough in positioning thinking. (A is the absolute value of RSSI at a distance of 1m from the transmitter; n is the absolute value of RSSI attenuated for every 1m away from the transmitter.) Background technique [0002] The development of the Internet of Things and the market demand for indoor positioning have led to the development of related research on indoor positioning. The traditional thinking is that the denser the network planning,...
