Problems solved by technology

[0003] However, during the research and practice of the prior art, the inventors of the present invention found that due to the large gap between the model constructed by the prior art and the actual use situation, especially in the presence of obstacles, it will lead to The error between the measured distance and the actual distance becomes large, and due to the uncertainty of radio space loss, when the spacer is metal or concrete, the attenuation is very large

Abstract

The invention discloses a wireless positioning method, device, terminal equipment and storage medium. The method includes: analyzing the uplink access parameters of the first equipment under test sent by a dedicated base station, and obtaining the first equipment under test by analyzing the uplink access parameters. Calculate the uplink data information of the device to obtain the first time parameter Ta1; analyze the second time parameter Ta2 sent by the dedicated base station to the distance measuring device about the first device under test accessing the dedicated base station; analyze the first time parameter Ta2 sent by the first device under test to the dedicated base station The data information of the third time parameter Ta3 is obtained, and the transmission power value of the first device under test is calculated; according to the above three time parameters, the distance between the first device under test, the dedicated base station and the ranging device is calculated respectively. The path length information and the corresponding included angle are combined with the transmission power value of the first device under test to determine the distance value and orientation information from the first device under test to the distance measuring device. The present invention can accurately determine the distance position of the wireless terminal based on the LTE standard of the wireless network.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless positioning method, device, terminal equipment and storage medium. Background technique [0002] The wireless positioning system can detect the position of people and objects through wireless signals. At present, with the development of society, there are more and more demands for location-based information services and control applications, and the research of wireless positioning technology has also received more attention. The most commonly used method in the current wireless positioning technology is to judge the distance by the strength of the power. The power field is strong, the distance is short, and the power field strength is small, the distance is long. The relationship between the two is obtained through the loss relationship of free space. It is shown that the propagation loss (also known as attenuation) of radio waves in free space...
