Abstract

The invention belongs to the technical field of wireless signal collection methods based on spatial relationships, and belongs to an intelligent collection method based on map information matching and location navigation and correction of collectors. Including map making, map road network design, collection program design, data collection, status analysis of collectors, and collection correction steps. The invention establishes a detailed indoor map road network and an outdoor map road network, and establishes a position estimation program to track the real-time position of collectors. Map the signal collected by the collector during walking with a specific location. Collectors do not need to design routes in advance. After setting the starting point, they can collect data at any speed and at any walking habit, which simplifies the collection process, improves collection efficiency and accuracy, and reduces the requirements for collectors.

Description

technical field [0001] The invention belongs to the technical field of wireless signal collection methods based on spatial relationships, and belongs to an intelligent collection method based on map information matching and location navigation and correction of collectors. Background technique [0002] With the rapid development of wireless communication and integrated circuits, various wireless network technologies have been widely used and built. The original intention of wireless network is to solve communication problems in various environments, and later it is also applied to the field of positioning, especially indoor positioning. Whether it is communication or positioning, it is necessary to understand and analyze the characteristic distribution of wireless signals in detail. Although the wireless signal characteristics can be modeled according to the location of the wireless base station and the wireless signal attenuation model. However, due to reflection, refract...
