Embodiment 1

[0054] Take Beidou positioning technology as an example, see figure 1 , is a system architecture diagram of Embodiment 1 of the present invention, including at least two reference positioning modules 11, a real-time positioning module 12, a computing module 13 and a mechanical driving module 14 arranged on the automatic mobile transportation facility. The reference positioning module 11 and the real-time positioning module 12 are both used to communicate with the Beidou positioning system to obtain positioning data with a time stamp. The Beidou positioning system includes multiple satellites in orbit.

[0055] The position of the reference positioning module 11 is fixed, and it has high-precision original position data, and the high-precision position data can be obtained through various current positioning technologies. The reference positioning modules 11 each save their own original position data.

[0056] Afterwards, the reference positioning module 11 communicates with ...

Embodiment 2

[0071] The reference positioning module 11 mentioned above, regarding the selection of the position of the reference positioning module 11, take the mobile guardrail as an example, the mobile guardrail will not move within a relatively large distance, and there will be non-mobile devices such as street lights nearby. Therefore, the reference positioning module 11 can be installed on non-mobile transportation facilities such as street lamps to improve positioning accuracy.

[0072] There are generally many street lights. At different times, the positioning information of the nearest street light can be determined according to the specific position of the mobile guardrail as reference information to compensate for the current positioning position of the automatic mobile traffic facility.

[0073] In the case where multiple reference positioning modules 11 are installed, such as a large number of installations on street lamps, a dynamic networking of the required reference positio...

Embodiment 3

[0075] Taking the mobile guardrail as an example, it includes multiple linked motion nodes, and the distance between adjacent nodes is within a certain range. With the help of this distance range, the positioning accuracy can be verified:

[0076] The automatic mobile transportation facility includes at least two moving nodes, and each moving node is provided with a corresponding real-time positioning module 12;

[0077] The calculation module 13 is also used to judge whether the distance between the current final positioning positions corresponding to two adjacent moving nodes satisfies a first preset condition; the first preset condition may specifically be the maximum sum of two adjacent nodes Minimum distance range interval;

[0078] The calculation module 13 is configured to compare the current final positioning position with the current preset position of the automatic mobile transportation facility when the distance satisfies a first preset condition.

[0079] On the c...

Abstract

The invention discloses a motion trail control system, device and method for an automatic mobile traffic facility. The system comprises at least two reference positioning modules, and a real-time positioning module, a calculation module and a mechanical driving module which are arranged on a traffic facility, wherein the reference positioning module is used for obtaining reference positioning datawith timestamps and calculating the reference positioning data with the original positioning data to obtain differential variables, the real-time positioning module is used for synchronously obtaining real-time positioning data and correcting the real-time positioning data according to differential variables at the corresponding moment to obtain the corresponding final positioning position, and the calculation module is used for comparing the final positioning position with a preset position of the corresponding time, determining deviation rectification data and controlling a mechanical driving module to enable the automatic mobile traffic facility to move from the final positioning position to the preset position. The system is advantaged in that compared with an embedded track and the like in the prior art, the trail control method is small in construction amount, is slightly influenced by the environment, is not easily damaged by a vehicle, and is high in track control efficiency.

Description

technical field [0001] The invention relates to the field of automatic mobile transportation facilities, in particular to a motion trajectory control system, device and method for automatic mobile transportation facilities. Background technique [0002] The mobile guardrail is a kind of road traffic facility that appears with the demand of road tidal traffic. It can adapt to tidal traffic by changing the direction of the variable lane in real time according to the change of traffic flow by moving to different positions. [0003] In order to achieve convenience and save manpower and other costs, the mobile guardrail needs to realize automatic movement, which involves the trajectory control problem in automatic movement. [0004] The trajectory control of the existing mobile guardrail is tracking, one of which is based on embedding tracks of different shapes on the road surface, and performing mechanical tracking and positioning according to the track guidance; the other way ...
