Indoor integrated positioning platform and positioning method

Abstract

The invention relates to an indoor integrated positioning platform and a positioning method. The indoor integrated positioning platform includes a system software layer, a device access layer, a service layer, a business integrated layer, a business software layer, and a presentation layer. The subsystem in each layer processes the data thereof through the service layer. An optical fiber communication network system and an RFID-based signal acquisition system import the data of different subsystems and realize data interaction between the subsystems and the indoor integrated positioning platform through the device access layer. The indoor integrated positioning platform adopts a honeycomb networking structure. Each device communicates with a gateway in a plurality of directions, and each device has a wireless signal relay function.

Description

technical field [0001] The invention relates to the field of positioning, in particular to an indoor comprehensive positioning platform and method. Background technique [0002] In the existing technology, for large-area monitoring scenarios, it is often necessary to deploy a large number of positioning nodes in the environment to achieve position monitoring and accurate movement trajectory monitoring of personnel in large-area monitoring scenarios, so as to achieve positioning from multiple angles. For the positioning of the upper and lower positions of the building, that is, the combination of two-dimensional positioning and three-dimensional positioning, more positioning nodes need to be arranged, which greatly increases the overall cost of the system.

[0002] In the existing technology, for large-area monitoring scenarios, it is often necessary to deploy a large number of positioning nodes in the environment to achieve position monitoring and accurate movement trajectory monitoring of personnel in large-area monitoring scenarios, so as to achieve positioning from multiple angles. For the positioning of the upper and lower positions of the building, that is, the combination of two-dimensional positioning and three-dimensional positioning, more positioning nodes need to be arranged, which greatly increases the overall cost of the system

[0003] In addition, in the existing technology, in order to achieve more accurate indoor positioning through RFID technology, the signal characteristics of other wireless transmission sources or the detection of tag signal strength are often used as an auxiliary, for example, by pre-storing signals at different reference positions Strength, after receiving the real-time tag signal strength, compare it with the stored signal strength, so as to determine the relative position range, but this technology needs to store a large amount of position signal strength information, in the face of large-area application environment When, for example, regional scope and multiple buildings, the storage data volume of the reference position strength information is large, and the operability is not strong

In another example, when the coverage of at least three transmitters is fully achieved at any positioning point, the position of the tag is positioned, and the exact position of the tag is obtained according to the triangular positioning algorithm. However, the layout of the antenna and the base station, The same area is large, and it will cause a waste of equipment resources in areas that do not need to be covered by multiple emission sources
