Background

The high-speed and large-capacity freight train has the advantages of large one-time loading capacity and strong transportation capacity, and is widely applied to bulk cargo transportation of coal, ore and the like in places such as stockyard, raw material warehouse of iron and steel production enterprise, wharf transfer base station and the like at present. After the bulk cargo is transported to a designated bin by a freight train, the bulk cargo is unloaded to a designated place by automatic dumping equipment or manual unloading. Along with the continuous improvement of the country to the environmental protection requirement, for the carriage after avoiding unloading arouses the raise dust in the in-process of traveling, a plurality of places and enterprise go out a series of regulations, bulk cargo transportation carriage is unloading the back, and remaining material weight and the volume in the carriage must not exceed certain limit, should keep the carriage cleanliness simultaneously. This requires that the bulk freight train must be cleaned after unloading and can leave after the cleanliness meets the requirements.

In order to solve the problems caused by manual cleaning, a plurality of enterprises and individuals at home and abroad develop mechanical and intelligent freight train carriage cleaning equipment and achieve certain effect. However, the current research mainly aims at the development of the carriage cleaning equipment body, and the cleanliness detection and evaluation methods after cleaning are less researched. Because the carriage cleans the regional difficult problems such as the dust degree is great often, the illumination condition is relatively poor, material and carriage colour are comparatively close, the cleanliness after accurate discernment carriage cleans provides the reference for follow-up operation, has certain degree of difficulty in the technique.

Detailed Description

Examples

The bulk cargo freight train car cleanliness detection device of the present embodiment, as shown in fig. 1, includes: the device comprises rails 5 arranged on two sides of a carriage 1 along the length direction of the carriage 1, a support frame 2 capable of moving on the rails 5, an expansion link 3 installed on the support frame 2 and an infrared laser detector 4 installed on the expansion link 3; the support frame 2 has the triangular supports of both sides and the crossbeam that is supported by the triangular supports, and telescopic link 3 installs on the crossbeam, and the crossbeam stridees across carriage 1 from the width direction of carriage 1. The telescopic rod 3 can be stretched in the vertical direction; the infrared laser detector 4 faces the bottom surface in the vehicle compartment 1; the telescopic rod 3 can be moved along the cross beam.

Thus, the three-axis movement of the infrared laser detector 4 is realized through the movement of the support frame 2 on the track 5, the movement of the telescopic rod 3 on the support frame 2 and the extension and retraction of the telescopic rod 3.

As shown in fig. 1, the plane to be detected and the coordinate axes of the car 1 are defined as follows: the bottom surface of the carriage is an E surface, two long surfaces vertical to the E surface are A, B surfaces respectively, and two short surfaces vertical to the E surface are C, D surfaces respectively; the vertical upward direction is the positive direction of the Z axis, the direction parallel to the A, B plane and pointing to the D plane is the positive direction of the Y axis, and the direction parallel to the C, D plane and pointing to the B plane is the positive direction of the X axis.

The specific working process is as follows:

(1) support frame 2 moves to the D face of laminating to carriage 1 along the Y direction, and telescopic link 3 moves to carriage 1 intermediate position along the X direction, and the length of telescopic link 3 is adjusted to the Z direction for red infrared laser detector 4 gets into the working range to suitable position.

(2) The infrared laser detector 4 starts to measure the distance between the car wall and the infrared laser detector 4 on the current Y section. And calculating the material coverage thickness according to the position difference between the previously known theoretical carriage wall position and the currently detected material surface.

(3) And measuring the covering thicknesses s1, s2, s3 and … sn by taking each resolution length delta l as a step, wherein the product of n and delta l is the sum of the lengths of the two vertical surfaces and the bottom surface of the carriage.

(4) The sum of the areas of the covering materials within the current interface range is (s 1+ s2+ s3+ … + sn) × Δ l.

(5) Assuming that the stepping amount of the infrared laser detector 4 in the Y-axis direction during each measurement is Δ Y, the sum of the volumes of the covering materials within the current interface range is (s 1+ s2+ s3+ … + sn) × Δ l × Δ Y.

(6) The support frame 2 advances by a stepping amount delta Y towards the C surface along the Y-axis direction, and the volume of the materials in the current interface is calculated according to the calculation mode.

(7) And when the support frame 2 finishes the distance in the whole Y-axis direction, the sum of the volumes of all the residual materials in the carriage is calculated in an accumulated mode.

The infrared laser detector 4 is connected with an upper computer so as to carry out volume calculation, result display and the like.

The following functions can be achieved by arranging appropriate sensors and controllers:

(1) local manual control mode: the bulk cargo freight train carriage cleanliness detection device in the working mode is realized through a wireless remote control handle or a button on a PLC control box.

(2) Local automatic control mode: firstly, automatic intelligent detection is realized according to the position and the attitude of the infrared laser detector sensed and calculated by the position sensing system and by combining a detection path planning algorithm and an intelligent collision avoidance algorithm. Secondly, if the accurate parking position of the carriage can be ensured, the size of the carriage is known and has no deformation, an automatic control mode of manual teaching-machine learning can be adopted. That is, the first time, the control system is manually controlled by the remote controller/button, the control system stores the key position and posture data, and the equipment automatically operates according to the previously memorized data in the later detection process.

(3) Remote automatic control mode: under the condition that the operation effect of the local automatic control mode is good, remote automatic one-key control can be realized according to equipment such as a network camera, a network switch and the like, and unmanned operation is completely realized.

The present invention is not limited to the above embodiment. All technical solutions formed by equivalent substitutions fall within the protection scope of the present invention.
