Technical Field

The invention relates to a railway maintenance technology, in particular to a device and a method for monitoring sand burying degree of a railway track.

Background

With the improvement of rail transit networks in northwest regions, the research and development of measures for dealing with yellow sand invasion on railways passing through desertification regions are particularly necessary. At present, protection forests or sand fixing belts are mainly built in areas with serious wind and sand damage, the cost is very high, and the protection of the whole line is difficult to realize. And monitoring part of lines on the road section with serious sand burying hazards by using an image monitoring system, and transmitting video or image information back to a control center for processing and then carrying out manual maintenance decision on the road. Due to the fact that the construction cost is too high, monitoring equipment is not arranged on a plurality of road sections, information of sand burying conditions cannot be obtained in time, and certain risks are brought to vehicle operation. In addition, how to timely identify the problem of burying the rails caused by some new activated sand sources and timely perform early warning and treatment is temporarily lacked in the prior art. .

The existing railway sand burying hazard protection is mainly implemented by building a protection forest on a related road section, or by arranging a high vertical sand barrier, a geogrid, digging a sand-intercepting ditch, building a sand-blocking wall, planting a branch sand barrier, laying sand and stones and other sand-fixing technologies. However, due to the sand storm and strong sunshine in the desert, the sand-proof grid is often torn by wind, and must be repaired and maintained regularly, resulting in very serious economic loss. Meanwhile, the railway line is too long, the economic cost for building the whole protective belt is too high, and the method is not practical. In addition, some researchers have tried to fix sand by spraying chemical materials, but they have been abandoned in a wide range of applications because of problems such as durability and environmental health. For monitoring of sand burial, railway departments try to install image monitoring systems in areas with serious sand burial hazards, and monitoring of the sand burial hazards of the railways is implemented in the modes of image acquisition, image processing, manual judgment and manual decision making. Because of fixed-point monitoring, monitoring points are limited, and the larger the monitoring range is, the higher the construction cost is, so the method is not adopted in a large range. In addition, necessary information cannot be given to a new sand source activation section, so that the vehicle operation safety cannot be fundamentally guaranteed. At present, the method mainly depends on manual inspection discovery. Therefore, a monitoring device capable of collecting the image of the rail with the geographic information and having a good image collecting effect is needed.

Delta may occur during subsequent processing of the region of interest_iIn case of rapid surge, i.e. obtaining a certain relation to t_i,δ_i,β_iAfter the data, can be to delta_i,β_iThe duration delta required to increase the fixed ratio is estimated, assuming that delta is based on the historical data obtained_iIncrease from 40% to 60% takes 2 days, then delta is detected_iAfter the train approaches the set threshold value, related personnel need to be arranged in time to clean the train so as to ensure the running safety of the train.

Not only here, can also install sensors such as laser radar on the train and replace and gather the lens 21, gather the corresponding signal through sensors such as laser radar, etc., and compare with historical signal, in order to confirm the dust and sand degree of burying, this method should also belong to an application of this case, also in the protection scope of the invention, the installation number, installation position and angle of lens and GPS sensor will only influence the quality and image result of formation of image at the same time, do not influence the main protection characteristic of the invention.

In summary, according to the device and method for monitoring sand burying degree of railway track provided by the invention, in the process of train running, the image acquisition equipment 2 can acquire the image of the track, send the acquired image and the geographical position information to the data processing center, and perform image processing by means of the computer equipment, so that the sand burying condition of the railway track at the image acquisition place can be obtained, and the light supplement lamp 22 can be installed on the trackLight is supplemented in a dark condition, and the sand and dust are blocked by the baffle 14 under the condition that the illumination is not influenced; after the image with longitude and latitude information is obtained, a database is established based on the acquired image information, and when the image is processed, the number of pixels of the rail and the sleeper in a single image needs to be calculated to be x₁,y₁When no sand burying condition occurs, data can be collected once every t days for detection, when sand dust is accumulated, the position is photographed for 1 time each time, a key area determined by detection is detected, an image collected by the key area is processed again, if delta is larger than or equal to 60%, the condition that the sand dust is equal to the height of the rail possibly occurs, a worker is dispatched to the key area to carry out on-site inspection on the rail in time, and the sand dust is removed; delta may occur during subsequent processing of the region of interest_iThe condition of rapid explosion also needs to be cleaned to ensure the running safety of the train, and the maintenance cost of the rail can be greatly reduced through the image acquisition equipment 2 and the subsequent processing of the image.
