Multi-level positioning method and system based on identity management

Abstract

The invention relates to the technical field of Internet of things positioning, and particularly relates to a multi-level positioning method and system based on identity management. The method includes the following steps: an identity management server registers positioning object information and establishes a mapping relationship between an ID of a positioning object and an object identifier (OID) of a positioning device; and the positioning device determines a positioning mode and sends a positioning mode conversion request command to the identity management server. According to the scheme of the invention, positioning sub-tags of each positioning technology are integrated in the positioning device, the positioning device is subjected to OID coding, the management of a positioning sub-tag ID is replaced by the management of the OID of the positioning device, and thus the complexity of managing the positioning object can be reduced; and the positioning device switches the positioningmode according to the requirements for the positioning accuracy in real environments, the positioning sub-tags of the positioning system with different accuracy levels are adopted to acquire locationinformation, and thus the positioning accuracy of the positioning system can be improved level by level.

Description

technical field [0001] The invention relates to the technical field of Internet of Things positioning, in particular to a multi-level positioning method and system based on identification management. Background technique [0002] Traditional satellite positioning technology has remarkable characteristics such as high efficiency, low cost, multiple functions, and wide application range, but the positioning accuracy is greatly affected by the environment in which the terminal is located. When the terminal is in a high-density building or in an indoor environment, the accuracy of the satellite signal that can be received is too weak, which greatly reduces its accuracy, so it cannot perform positioning calculations to complete positioning. The indoor positioning technology of the Internet of Things can solve the high building density or indoor environment positioning that the satellite positioning system cannot involve. [0003] The positioning technologies currently used in th...

Problems solved by technology

However, existing positioning technologies use positioning tag IDs with different encoding methods to identify positioning objects, and different positioning methods track positioning objects by managing positioning tag IDs. When the number of positioning tag IDs is large, each positioning technology provides The ID encoding methods of the positioning tags are different, and it will become difficult to manage the positioning objects by simply managing the positioning tag ID.
