Description

Technical Field

[0001] The invention relates to the field of coke oven machine and coke side coke flow plate control, and in particular to a coke flow plate cleaning system based on visual analysis control. Background Art

[0002] The automatic cleaning of coke ovens and coke side coke plates has always been a problem that has plagued the coking industry. Therefore, the prior art generally uses a coke plate cleaning device based on visual analysis control for control, collects image information through a camera or a video device, determines whether the coke plate needs to be cleaned, and plans the working process of the coke plate when cleaning is required. However, in the prior art, the control of the moving route of the coke plate is not accurate enough, resulting in the cleaning device not cleaning the coke plate cleanly. Therefore, it is necessary to manually clean the residual coke on the coke plate again. In severe cases, a mechanical mechanism is required to clean it. Therefore, the disadvantage is that the cleaning is not clean and the degree of intelligence is not high, which affects the unmanned operation of the equipment in the later stage. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention discloses a coke plate cleaning system based on visual analysis control, which specifically includes:

[0004] Camera, collecting image information on the focusing plate;

[0005] A cylinder A position sensor installed on the cylinder A for collecting operating position information of the cylinder A;

[0006] A cylinder B position sensor installed on the cylinder B for collecting operating position information of the cylinder B;

[0007] A visual analysis server receiving the image information transmitted by the camera, wherein the visual analysis server determines whether the residual coke on the coke removal plate affects the closing of the furnace door according to the received image information, and outputs a control instruction for the coke removal plate cleaning device and the moving speeds of the oil cylinder A and the oil cylinder B;

[0008] A PLC control unit receives data information transmitted by the visual analysis server, the cylinder A position sensor, and the cylinder B position sensor. The PLC control unit controls the opening of the cylinder A proportional valve and the cylinder B proportional valve according to the speed information of the cylinder A and the cylinder B, and performs closed-loop automatic adjustment on the operation of the coke plate cleaning device through the moving distance fed back by the cylinder A position sensor and the cylinder B position sensor, and controls the synchronous operation of the cylinder A and the cylinder B.

[0009] When the visual analysis server controls the coke plate cleaning device: first, the top position of the rake hand of the coke plate cleaning device is set to the origin (0, 0), and after analyzing the image acquired by the camera, the coordinates (x, y) of the vertex position of the coke plate are determined, and the rake hand of the coke plate cleaning device is moved to the vertex position of the coke plate, and the residual focus cleaning operation is performed according to the planned route, and finally the operation is stopped at the coordinate position (x', y').

[0010] When the coke plate cleaning device has finished cleaning, the camera is used to take pictures again and transmitted to the visual analysis server for analysis and judgment. If the cleaning is qualified, the cleaning device is retracted to proceed to the next step; if the cleaning is unqualified, the cleaning action is repeated 2 to 3 times.

[0011] The visual analysis server determines the amount of residual coke based on the received image information. If the residual coke is insufficient, it is determined that it will not affect the closing of the furnace door and the coke removal plate cleaning will not be started. If the residual coke is excessive, the coke removal plate cleaning device will be controlled to start working.

[0012] Due to the adoption of the above-mentioned technical scheme, the present invention provides a coke plate cleaning system based on visual analysis control, which analyzes and judges the collected data based on the image acquisition principle and the visual image analysis principle, judges the amount of coke on the coke plate, judges whether the coke plate needs to be cleaned, and plans the moving route of the coke plate rake head when cleaning is required and feeds back to the PLC control unit, and controls the output of the hydraulic proportional valve and receives the data of the cylinder position sensor to control the cleaning device to clean the coke plate in real time in a closed-loop manner, thereby meeting the normal operation of the coke oven machine. Therefore, the system realizes the fully automatic production of the coking equipment on the machine and coke side, which is convenient for the realization of the overall unmanned intelligent production of the coke oven in the future.

[0017] Figure 4 The control wiring diagram of the coke plate cleaning system based on visual analysis control of the present invention is DETAILED DESCRIPTION

[0018] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention:

[0019] like Figure 1 and Figure 4 The system for cleaning the coke plate based on visual analysis control shown in the figure comprises a camera 1, a visual analysis server 2, an oil pump 3, a cylinder A proportional valve 4, a cylinder A position sensor 5, a cylinder B proportional valve 6, a cylinder B position sensor 7 and a PLC control unit 8. The camera 1 is used to collect image information on the coke plate, the cylinder A position sensor 5 is used to collect the operating position information of the cylinder A, and the cylinder B position sensor 7 is used to collect the operating position information of the cylinder B. The camera 1 transmits the collected image information to the visual analysis server 2.

[0020] The visual analysis server 2 determines whether the residual coke on the coke plate affects the closing of the furnace door according to the received image information, and outputs the control instructions for the coke plate cleaning device and the moving speeds of the cylinders A and B. The PLC control unit 8 receives the data information transmitted by the visual analysis server 2, the cylinder A position sensor 5, and the cylinder B position sensor 7, controls the opening of the cylinder A proportional valve 4 and the cylinder B proportional valve 5 according to the speed information of the cylinders A and B, and performs closed-loop automatic adjustment on the operation of the coke plate cleaning device through the moving distance fed back by the cylinder A position sensor 5 and the cylinder B position sensor 7, and controls the synchronous operation of the cylinders A and B.

[0021] like Figure 2 and Figure 3 The workflow of a coke plate cleaning system based on visual analysis control is as follows:

[0022] S1: Before closing the furnace door, start the camera 1 to take a picture and transmit it to the visual analysis server 2 for analysis. According to the algorithm, if the residual coke is not enough to affect the closing of the furnace door, the coke plate cleaning will not be started; if the residual coke is too much, the visual analysis server 2 will plan the moving route of the rake head of the coke plate cleaning device, and output the speed and distance of the two cylinders to the PLC control unit 8.

[0023] S2: Start the oil pump before cleaning the coke plate, set the top position of the rake head of the coke plate cleaning device to the origin (0, 0), and coordinate the action of cylinder A and cylinder B to move the rake head to the top of the coke plate (x, y).

[0024] S3: The PLC control unit controls the opening of the proportional valve of cylinder A and the proportional valve of cylinder B according to the received moving speeds of the two cylinders, and performs closed-loop automatic adjustment on the operation of the coke plate cleaning device through the moving distances fed back by the cylinder A position sensor 5 and the cylinder B position sensor 7 to ensure the synchronization of the operation of the two cylinders.

[0025] S4: When the rake hand of the coke plate cleaning device reaches the coordinate (x', y'), the coke plate cleaning operation is stopped, and the camera 1 is started to take pictures and transmitted to the visual analysis server 2 for analysis. According to the algorithm, when the degree of cleaning is sufficient to close the furnace door, the coke plate cleaning device is retracted; if not, the cleaning action is repeated 2 to 3 times, and then the coke plate cleaning device is retracted.

[0026] Furthermore, the system detection and control process can be divided into three stages:

[0027] After receiving the command, the camera first takes a photo and sends it to the visual analysis server for analysis, determines the residual focus situation on the focus plate at this time, and plans the moving route of the rake head.

[0028] The rake head of the coke plate cleaning device starts to move according to the planned moving route and feeds back the cylinder position to the PLC control unit in real time. The PLC control unit then synchronizes and coordinates the speeds of the two cylinders through the proportional valve.

[0029] After cleaning, take photos again for analysis. If the cleaning is qualified, retract the cleaning device and proceed to the next step; if the cleaning is unqualified, repeat the cleaning action 2 to 3 times.

[0030] First, in the first stage, the top position of the rake hand of the coke removal plate cleaning device is set as the origin (0, 0), and the coordinates (x, y) of the top position of the coke removal plate are determined after analyzing the photos taken by the camera.

[0031] Secondly, the rake hand of the coke plate cleaning device is moved to the top position of the coke plate, and the cleaning operation is performed according to the planned route, and finally the operation is stopped at the coordinate position (x', y').

[0032] Finally, the cleaning process is concluded by taking photos again for analysis or repeated 2 to 3 times to achieve the purpose of automatically, accurately and reliably cleaning the focus plate.

[0033] Based on the visual analysis of the coke plate conditions, this system, combined with a reliable coke plate cleaning device and an advanced PLC control system, further realizes the fully automatic production of coking equipment on the machine and coke sides, facilitating the realization of overall unmanned and intelligent production of coke ovens in the future.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
