Method for zigbee indoor location networking design and corresponding simplification

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,...

Problems solved by technology

However, in practical applications, the interference of the non-ideal local environment on the signal and the impact of object movement on the acquisition of signal strength are objective and practical, and it is difficult to solve the problem through theoretical research in an ideal environment.
