Embodiment 1

[0120] figure 1 The flow chart of a bus U-turn detection method provided by Embodiment 1 of the present invention, this embodiment can be applied to the situation where the satellite positioning unit and the inertial measurement unit are combined to detect whether the bus is U-turn, thereby broadcasting the station information, the method can Performed by the U-turn detection device of the bus, the U-turn detection device of the bus can be implemented by software and / or hardware, and can be configured in a computer device, specifically including the following steps:

[0121] Step 101, determine the route of the bus.

[0122]Bus (Bus, also known as bus, bus, etc.), refers to following a fixed route on urban roads. There are multiple stops on the route, with or without fixed shift times, and exclusive road numbers (such as No. 960, No. 195A, No. 35, etc.), motor vehicles that stop at the station to allow passengers to get on and off, and to carry passengers for travel. The gen...

Abstract

The embodiment of the invention provides a bu s U-turn detection method and a device, computer equipment and a storage medium, and the method comprises the steps: determining a driving route of the bus, setting a plurality of stations on the route, determining an area surrounding the stations as a target area if the bus drives and turns around to reach a certain station along the route, when a bus runs along a route, calling a satellite positioning unit to detect the position of the bus, calling an inertial measurement unit to detect the posture of the bus, when the bus runs to the target area, converting the position and the posture into various kinds of feature information, and detecting the running state of the bus in the target area is detected according to the various kinds of feature information; if the driving state is U-turn, broadcasting the arrival information to the stations in the target area, and enriching the dimension of sensing data by combining the satellite positioning unit and the inertial measurement unit, so that the accuracy of detecting the U-turn of the bus is improved, the station information of the to-be-arrived station is accurately broadcasted after the U-turn, and passengers can go out conveniently.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of public transportation, and in particular to a method, device, computer equipment and storage medium for U-turn detection of public transportation. Background technique [0002] The bus is one of the public transportation means for users to travel. When the bus arrives at the set station, it will broadcast the station information to remind the user to get ready to get off. [0003] At present, judging whether the bus arrives at the station mainly depends on satellite positioning. However, the accuracy of satellite positioning itself is low, and it is easily affected by the environment. Especially in places with dense buildings such as viaducts in urban areas, the signal of satellite positioning will drift. This phenomenon further deteriorates the accuracy of satellite positioning. [0004] In order to cover different streets in the urban area, the route of the bus has to turn bac...
