Problems solved by technology

[0006] In view of the above deficiencies in the prior art, the object of the present invention is to provide a visual measurement-based method for the auxiliary synchronous coordination control of railway rescue double-car hoisting and recovery, which obtains the spatial geometric data information of the scene through the visual measurement terminal and sends it back to the background server , and formulate a real-time solution to the problem of uneven load during the double-vehicle coordinated hoisting and recovery process. The means are:

Embodiment Construction

[0049] After the railway accident, the two cranes carried out coordinated hoisting, combined with the internal working diagram of the visual measurement terminal ( Figure 4 ) and a schematic diagram of the field work of the visual measurement terminal ( Figure 6 ) shows that the real-time image acquisition of the scene environment is carried out by the digital camera, and the digital camera is mainly composed of a visual sensor and an image acquisition card, which are the key to image acquisition. The function of the image acquisition card is to control the visual sensor to collect signals (including the image information of the two cranes and the hoisted locomotive body), quantize the collected analog signals and convert them into digital images, and then store them in the frame memory .

[0050]The digital image stored in the frame memory is transmitted to the industrial computer through the data interface, and the industrial computer will process the digital image. In o...

Abstract

The invention discloses a visual measurement-based auxiliary synchronous coordination control method for double-vehicle cranes in railway rescue, which is used to assist the synchronization problem of double-vehicle cranes in emergency rescue of railway accidents; using a synchronization terminal, a visual measurement terminal, and a background server, through visual measurement The spatial three-dimensional coordinate data information of the object at the accident site is obtained in real time, and the background server will process, calculate, and solve the data information to formulate a real-time hoisting plan, which is for the crane operator when the load is uneven when the two cranes are hoisting together. Provide guidance.

Description

technical field [0001] The invention relates to the field of railway emergency rescue, in particular to a visual measurement-based dual-car hoisting auxiliary synchronization device for railway rescue. Background technique [0002] Traffic accident rescue is an important part of railway transportation safety production, the success or failure of rescue work is directly related to the change of accident nature and the degree of accident loss. In order to ensure the safe, fast and orderly rescue, improve the overall rescue work, and minimize the accident loss. Once the transportation interruption occurs, it must be actively dealt with, and the traffic can be restored quickly to minimize the transportation interruption time. Making a reasonable emergency rescue plan has become the primary task of the traffic accident rescue organizers and commanders. [0003] In traffic accidents, due to the configuration and performance of the crane, it is not possible to lift the maximum mas...
