Construction site personnel positioning alarm method based on base station positioning technology

Abstract

The invention belongs to the technical field of base station positioning, and discloses a construction site personnel positioning alarm method based on a base station positioning technology, and the method specifically comprises the steps: S1, obtaining the personnel number, the longitude, the latitude, the unix timestamp T and the instantaneous speed value of a building worker at a T moment; s2, transmitting the data collected at the moment to a background server, and extracting historical data of a plurality of groups of unix timestamps and speed data of the personnel by the background server according to the number of the personnel; s3, generating a prediction model by using polynomial fitting according to the historical data, predicting the running speed at the current moment by using the prediction model, and correcting the actually detected coordinate position according to the proportion between the predicted speed and the actual speed; and S4, judging whether the point location exceeds the electronic fence according to the predicted longitude and latitude, and giving an alarm if the point location exceeds the electronic fence. By using the positioning technology disclosed by the invention, the high false alarm rate caused by poor positioning precision of the base station is reduced.

Description

technical field [0001] The invention belongs to the technical field of base station positioning, and in particular relates to a method for locating and alarming personnel on a construction site based on the base station positioning technology. Background technique [0002] The positioning technology mainly includes base station positioning, GPS positioning, UWB positioning, etc. The most commonly used technology is base station positioning. According to different communication technologies, each positioning technology has different positioning accuracy. For example, the positioning accuracy of 4G base station is about 10 meters, and the positioning accuracy of 5G base station is about 5 meters. Compared with other positioning technologies, the accuracy of base station positioning is poor. At present, in order to facilitate centralized management, the positioning of construction workers during the construction process is to delineate electronic fences on the construction sit...

Compared with other positioning technologies, the accuracy of base station positioning is poor

At present, in order to facilitate centralized management, the positioning of construction workers during the construction process is to delineate electronic fences on the construction site on the map, and use mobile phones to locate the base station of construction workers (most construction workers' mobile phones do not have GPS modules). Workers outside the range of the electronic fence send an alarm, but due to the low positioning accuracy of the base station, many false positives and false positives are caused
