UWB-based height-limiting height determination method, device and system

Abstract

An embodiment of the invention provides a UWB-based height-limiting height determination method, device and system. The UWB-based height-limiting height determination method comprises the steps of: acquiring a first distance between a target vehicle and a first UWB unit, wherein the first distance is determined through transmitting a distance measurement signal to the first UWB unit by a vehicle-mounted UWB unit; and acquiring a second distance between the target vehicle and a second UWB unit determined by sending the distance measurement signal to the second UWB unit by the vehicle-mounted UWB unit, and determining the height-limiting height of a road height-limiting frame according to the first distance and the second distance. By using the UWB-based height-limiting height determinationmethod and the system, the measurement of the height-limiting height of the road height-limiting frame can be realized; moreover, based on the features of insensitivity to channel attenuation, high penetrating performance, good anti-multipath effect and the like of the UWB , the interference in the distance measurement process can be reduced by the UWB, the measurement precision is improved, the height-limiting height of the road height-limiting frame can be accurately measured through using the UWB, the driving safety is ensured, and accidents are reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and in particular, to a method, device and system for determining height limit based on UWB. Background technique [0002] In the field of intelligent transportation technology, with the vigorous development of modern urban transportation, the number of super-large trucks has increased rapidly, and the incidence of accidents such as stuck bridges and bridge collisions caused by super-large trucks is also increasing year by year. In order to limit the behavior of large trucks with super high loads, most traffic management departments take measures such as adding road overhead and height limit signs to prevent them. The existing height limit signs are generally set in front of the height limit device. The height limit on the card reminds the driver to pay attention to the height limit device in front, and enables the driver to independently determine whether to pass the r...
