Problems solved by technology
In the existing indoor positioning solution for personnel in the factory area, there are many problems that affect the final user experience, such as inaccurate personnel positioning results, offset of personnel positioning points, and easy disconnection of personnel positioning signals.
The main reasons for these problems are as follows: 1. Traditional indoor positioning technology uses a single local area signal such as Bluetooth, WiFi, and RFID to calculate the position, which is greatly affected by the environment; 2. The specificity of the positioning results of traditional indoor positioning methods The value is usually processed by a filtering algorithm, which lacks targeted optimization for specific locations such as corners, factory entrances and exits, which affects the final trajectory; 3. Traditional indoor positioning methods lack positioning optimization for vertically connected structures such as stairwells and elevators , resulting in error-prone floor determinations in these areas

The invention discloses an indoor positioning method based on ZigBee and 2.4G dual-mode, which specifically includes the following steps: S1 installs or connects a positioning system at an application site to be positioned, and the positioning system includes a plurality of positioning modules; A plurality of the positioning modules in the positioning system respectively obtain positioning data within the scope of the positioning system; S3 judges the type of the positioning data according to the obtained header symbol of the positioning data; S4 judges the type of the positioning data according to the position of the positioning data Type, match the corresponding data parser for data analysis, and obtain the analysis data respectively; S5 performs data fusion of different types of analysis data to obtain positioning data in a unified format. The positioning accuracy is high, which meets the needs of indoor positioning capabilities for personnel generated in the process of safety supervision and construction of factories and enterprises.
Description
technical field [0001] The invention relates to the technical field of factory safety supervision, in particular to an indoor positioning method based on ZigBee and 2.4G dual-mode. Background technique [0002] With the continuous improvement of the safety management system of chemical enterprises, the status of safety production in enterprise management has been increasing day by day, and it has become one of the important indicators for the competent authorities to assess each enterprise. As one of the important means of safety supervision, the indoor real-time positioning of personnel within the factory area has gradually attracted the attention of various factories. In the existing indoor positioning solution for personnel in the factory area, there are many problems that affect the final user experience, such as inaccurate personnel positioning results, offset of personnel positioning points, and easy disconnection of personnel positioning signals. The main reasons for...
