Description

Technical Field

[0001] This application relates to the technical field of coal sampling and sample preparation technology and equipment, and particularly relates to an operation monitoring system and method for a sampler. Background Art

[0002] When conducting coal quality testing, coal sampling and sample preparation are required. During the process of coal sampling and sample preparation, as the first sampling device in the whole process of the mechanical coal sampling and sample preparation system, the sampling accuracy of the sampler determines the accuracy of the entire sampling and sample preparation system. At the same time, as the only device related to the coal conveying belt, the stable operation of the sampler not only affects the stability of the entire mechanical coal sampling and sample preparation system, but also directly affects the normal operation and production safety of the main transportation belt. If the sampler equipment fails, especially if the cutter of the sampler equipment stays on the belt coal flow for more than a certain period of time, it will lead to the interruption of sampling work, and even accidents such as coal sample accumulation and damage to the coal conveying belt. Even if the above-mentioned failure does not occur, when the cutter of the sampler equipment is outside the cutting area of the belt coal flow, if the stay time is too long, it also indicates that the working state of the sampler equipment is abnormal. In the related art, only by manually observing the operation state of the sampler, it is impossible to monitor in real time, with low efficiency and large errors. Summary of the Invention

[0003] The first object of this application is to propose an operation monitoring system for a sampler, which can quickly make judgments and issue warnings, thus effectively avoiding abnormal sampling accidents caused by failures of the sampler 1 equipment.

[0004] The second object of this application is to propose an operation monitoring method for a sampler that executes the operation monitoring system of the sampler.

[0005] To achieve the above first object, the first aspect of this application proposes an operation monitoring system for a sampler, which is applied above the coal conveying belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8, and a timer, where:

[0006] An angle sensor 2 is set on the sampler 1 for monitoring the rotation angle of the sampler 1, and a zero-degree line 4 is set, and the zero-degree line 4 is the zero-degree line of the angle sensor 2;

[0007] Based on the zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, and a fourth position area 8 are set in the cross-sectional area of the sampler 1 and the coal conveying belt 3. The first position area 5 is an area where the angle is greater than 0 degrees and less than 60 degrees, the second position area 6 is an area where the angle is greater than or equal to 60 degrees and less than or equal to 90 degrees, the third position area 7 is an area where the angle is greater than 90 degrees and less than 220 degrees, and the fourth position area 8 is an area where the angle is greater than 220 degrees and less than 360 degrees;

[0008] A timer for judging the running state of the sampler 1 according to the residence time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 respectively.

[0009] In addition, the running monitoring system of the sampler proposed above according to the present application may further have the following additional technical features:

[0010] In some embodiments, the sampler 1 rotates approximately around the center of the coal conveying belt 3 to collect coal samples transported on the coal conveying belt 3.

[0011] In some embodiments, when the sampler 1 does not take coal samples, the sampler 1 normally stops in the second position area 6. When the sampler 1 takes coal samples, a sampling signal is sent out, and the sampler 1 rotates clockwise, passes through the third position area 7 and enters the fourth position area 8, cuts and sweeps the coal samples on the coal conveying belt 3, and continues to rotate through the first position area 5 under the action of inertia, and stops in the second position area 6.

[0012] To achieve the second above-mentioned purpose, a method for monitoring the operation of a sampler of a running monitoring system of a sampler is proposed in the second aspect of the present application. The method includes:

[0013] Obtaining the first residence time, the second residence time, the third residence time, and the fourth residence time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 respectively;

[0014] Judging the running state of the sampler 1 according to the first residence time, the second residence time, the third residence time, and the fourth residence time, and executing the running strategy corresponding to each running state.

[0015] In some embodiments, the judging the running state of the sampler 1 according to the first residence time, the second residence time, the third residence time, and the fourth residence time, and executing the running strategy corresponding to each running state includes:

[0016] When the fourth residence time of the sampler 1 in the fourth position area 8 exceeds a preset time threshold, it is determined that the sampler 1 is in a fault state, and a shutdown and maintenance strategy is executed;

[0017] When the sampler 1 stays in the first position area 5 or the third position area 7, and the first residence time or the third residence time exceeds a preset time threshold, it is determined that the sampler 1 is in an abnormal state with abnormal operation, and a shutdown and maintenance strategy does not need to be executed, but a maintenance strategy needs to be executed;

[0018] When the sampler 1 is within the second position area 6 and the second residence time exceeds the preset time threshold, it is determined that the sampler 1 is in the normal state of normal residence, and the sampler 1 is normal.

[0019] The present application discloses an operation monitoring system and method for a sampler. The system is applied above the coal conveying belt 3 and includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8, and a timer. An angle sensor 2 is provided on the sampler 1 for monitoring the rotation angle of the sampler 1. The zero-degree line 4 is set. A first position area 5 with an angle greater than 0 degrees and less than 60 degrees, a second position area 6 with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees, a third position area 7 with an angle greater than 90 degrees and less than 220 degrees, and a fourth position area 8 with an angle greater than 220 degrees and less than 360 degrees are set in the cross-sectional area between the sampler 1 and the coal conveying belt 3. The timer is used to judge the operation state of the sampler 1 according to the residence time of the sampler 1 in each position area. Thus, it is possible to quickly make a judgment and issue a warning, thereby effectively avoiding abnormal sampling accidents caused by equipment failures of the sampler 1.

[0020] Additional aspects and advantages of the present application will be given in part in the following description, will become apparent in part from the following description, or will be understood through the practice of the present application. Brief Description of the Drawings

[0021] The above and / or additional aspects and advantages of the present application will become apparent and easy to understand from the following description of the embodiments in conjunction with the drawings, in which:

[0022] Figure 1 is a schematic structural diagram of an operation monitoring system for a sampler provided by an embodiment of the present application;

[0023] Figure 2 is a schematic flowchart of an operation monitoring method for a sampler provided by an embodiment of the present application. Detailed Embodiments

[0024] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation of the present application.

[0025] The operation monitoring system of the sampler according to the embodiment of the present application will be described below with reference to the drawings.

[0026] Figure 1 is a structural diagram of an operation monitoring system for a sampler according to an embodiment of the present application.

[0027] As Figure 1As shown in the figure, the operation monitoring system of the sampler in the embodiment of the present application. The operation monitoring of the sampler is applied above the coal conveying belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8, and a timer (not shown in the figure), where:

[0028] An angle sensor 2 is set on the sampler 1 for monitoring the rotation angle of the sampler 1, and a zero-degree line 4 is set. The zero-degree line 4 is the zero-degree line of the angle sensor 2;

[0029] Based on the zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, and a fourth position area 8 are set in the cross-sectional area between the sampler 1 and the coal conveying belt 3. The first position area 5 is the area where the angle is greater than 0 degrees and less than 60 degrees. The second position area 6 is the area where the angle is greater than or equal to 60 degrees and less than or equal to 90 degrees. The third position area 7 is the area where the angle is greater than 90 degrees and less than 220 degrees. The fourth position area 8 is the area where the angle is greater than 220 degrees and less than 360 degrees;

[0030] The timer is used to judge the operation state of the sampler 1 according to the residence time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 respectively.

[0031] In some embodiments, the sampler 1 is applied in the process of coal sampling and sample preparation. The purpose of coal sampling and sample preparation is to obtain a test coal sample whose test results can represent the whole batch of coal to be sampled. The basic process of coal sampling and sample preparation is first to collect a considerable amount of coal from many points distributed in the whole batch of coal, that is, the primary sub-samples, and then directly combine or reduce and combine each primary sub-sample into a total sample. Finally, this total sample is made into the required number and type of test coal samples through a series of sample preparation procedures. Among them, the test coal samples are used for coal quality detection. Thus, the operation state of the equipment of the sampler 1 can be effectively monitored. When it stays on the belt coal flow (the fourth position area 8) for more than a certain time, or stays in the area outside the belt coal flow cutting area (the first position area 5 or the third position area 7) for too long, it can be quickly judged and a warning can be issued. Therefore, accidents such as the interruption of sampling work, the accumulation of coal samples, and the damage of the belt caused by the failure of the sampler 1 can be effectively avoided. At the same time, the abnormal working state of the sampler 1 can also be pre-warned in advance to ensure the maintenance prompt before the occurrence of equipment accidents and avoid greater accidents.

[0032] Optionally, the sampler 1 rotates around the coal conveying belt 3 approximately as the center of a circle to collect the coal samples transported on the coal conveying belt 3.

[0033] Further, when the sampler 1 does not take coal samples, the sampler 1 normally stops in the second position area 6. When the sampler 1 takes coal samples, a sampling signal is sent out, and the sampler 1 rotates clockwise, passes through the third position area 7 and enters the fourth position area 8, cuts and sweeps the coal samples on the coal conveying belt 3, and continues to rotate through the first position area 5 under the action of inertia and stops in the second position area 6.

[0034] The present application discloses an operation monitoring system for a sampler. The system is applied above the coal conveying belt 3 and includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8 and a timer. An angle sensor 2 is arranged on the sampler 1 to monitor the rotation angle of the sampler 1; a zero-degree line 4 is set, and a first position area 5 with an angle greater than 0 degrees and less than 60 degrees, a second position area 6 with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees, a third position area 7 with an angle greater than 90 degrees and less than 220 degrees, and a fourth position area 8 with an angle greater than 220 degrees and less than 360 degrees are set in the cross-sectional area between the sampler 1 and the coal conveying belt 3. The timer is used to judge the operation state of the sampler 1 according to the residence time of the sampler 1 in each position area. Thus, it is possible to quickly make a judgment and issue a warning, thereby effectively avoiding abnormal sampling accidents caused by equipment failures of the sampler 1.

[0035] Figure 2 It is a schematic flow chart of an operation monitoring method for a sampler according to an embodiment of the present application.

[0036] Step 201, obtain the first residence time, the second residence time, the third residence time, and the fourth residence time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 respectively.

[0037] In some embodiments, the first residence time, the second residence time, the third residence time, and the fourth residence time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 can be collected through a timing device, such as an electronic timer, but it is not limited thereto.

[0038] Step 202, judge the operation state of the sampler 1 according to the first residence time, the second residence time, the third residence time, and the fourth residence time, and execute the operation strategy corresponding to each operation state.

[0039] In some embodiments, an implementation manner of determining the operating state of sampler 1 based on the first residence time, the second residence time, the third residence time, and the fourth residence time and executing the operating strategy corresponding to each operating state may be that when the fourth residence time of sampler 1 in the fourth position area 8 exceeds a preset time threshold, it is determined that sampler 1 is in a faulty state, and a shutdown maintenance strategy is executed; when sampler 1 stays in the first position area 5 or the third position area 7 and the first residence time or the third residence time exceeds the preset time threshold, it is determined that sampler 1 is in an abnormal state with abnormal operation, and the shutdown maintenance strategy does not need to be executed, but the inspection strategy needs to be executed; when sampler 1 is in the second position area 6 and the second residence time exceeds the preset time threshold, it is determined that sampler 1 is in a normal state of normal residence, and sampler 1 is normal. Thus, the monitoring of the faulty state in the intelligent operation process of sampler 1 is effectively realized, and the operation and maintenance efficiency of sampler 1 is greatly improved.

[0040] Among them, the preset time threshold may be 2 seconds, but is not limited thereto, and can be adjusted according to the process of coal sampling and sample preparation.

[0041] This application discloses a method for monitoring the operation of a sampler. The first residence time, the second residence time, the third residence time, and the fourth residence time of sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8 are obtained respectively; based on the first residence time, the second residence time, the third residence time, and the fourth residence time, the operating state of sampler 1 is judged, and the operating strategy corresponding to each operating state is executed. Thus, accidents such as the interruption of sampling work, the accumulation of coal samples, and the damage of the belt caused by equipment failures of sampler 1 can be effectively solved, and early warning of the abnormal working state of sampler 1 equipment can be carried out to avoid greater accidents.
