The invention discloses a vehicle body posture detection device and a dynamic offset detection system for a contact line. The vehicle body posture detection device comprises a first vehicle bottom image acquisition unit, a second vehicle bottom image acquisition unit and a processor, wherein the first vehicle bottom image acquisition unit and the second vehicle bottom image acquisition unit are arranged at the bottom of a vehicle body; a lighting axis of the first vehicle bottom image acquisition unit faces a first rail and is used for acquiring contour and position data of the first rail; a lighting axis of the second bottom image acquisition unit faces a second rail and is used for acquiring the contour and position data of the second rail; the processor is used for executing the following steps of step 1, computing a first posture of the vehicle body according to the contour and position data of the first rail, and computing a second posture of the vehicle body according to the contour and position data of the second rail; and step 2, verifying the first posture through the second posture, and when the first posture passes verification, taking the first posture as the current vehicle body posture. According to the vehicle body posture detection device, real-time detection of the posture of the vehicle body is realized, and the accuracy of vehicle body posture detection can be improved.
Description
technical field [0001] The invention relates to the field of rail transportation, in particular to a vehicle body posture detection device and a contact line dynamic offset detection system comprising the vehicle body posture detection device. Background technique [0002] The subway has the advantages of saving land, large transport capacity, and fast speed, and is an important part of urban transportation. In order to understand the real-time operation of the subway train and ensure the safe operation of the subway train, it is necessary to detect the attitude of the car body in real time. [0003] The purpose of vehicle body posture detection is to obtain the dynamic deviation limit of the locomotive and vehicle, and then to judge whether the locomotive has scratched with the adjacent vehicle or whether it exceeds the limit during operation. Existing car body attitude detection methods include: using laser ranging technology to detect the offset of the rolling stock or w...
