DETAILED DESCRIPTION

[0030] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0031] Embodiment 1

[0032] Please refer to Figures 1-6 As shown in the figure, an online monitoring system for the automatic metering and dosing device for coal flotation, comprising a dosing assembly and a monitoring assembly, the monitoring assembly comprising an acquisition module, a processing module and an execution module;

[0033] The acquisition module acquires dosing equipment structure data, pipeline data and falling deviation data, and transmits the acquired data to the processing module; the dosing equipment structure data includes equipment vibration data and equipment humidity data; the pipeline data includes pipeline size data, pipeline resistance data and dosing intensity data;

[0034] The processing module processes the dosing equipment structure data, pipeline data and falling deviation data transmitted by the acquisition module, and generates an execution signal according to the processing result, which is then transmitted to the execution module;

[0035] The data processing and analysis method of the processing module is as follows:

[0036] The equipment vibration data at the same time transmitted by the acquisition module is subjected to a de-extreme value averaging operation to obtain the equipment vibration average value, and then the equipment vibration average values at each time are arranged in the order of acquisition time, and coordinate points are plotted in a binary coordinate system established with the acquisition time and the equipment vibration average value, the adjacent coordinate points are connected, the slope of each segment is calculated, and according to the inclination direction, the positive slope value Zx and the negative slope value Fx are marked, and then the absolute values of the positive slope value Zx and the negative slope value Fx are compared;

[0037] If the absolute value of the positive slope value Zx and the negative slope value Fx gradually decreases over time, it indicates that the device vibration data gradually tends to be stable, and the change trend of the slope can be used to determine when the device vibration data reaches a stable state; if the absolute value of the positive slope value Zx and the negative slope value Fx gradually increases over time, it indicates that the device vibration data fluctuates greatly, and the starting time is determined, if the starting time is short, it is determined that it is caused by the device starting, if the starting time is long, it is determined that the device has a fault, and a signal is transmitted to the control device to suspend work for device maintenance operation; if the absolute value of the positive slope value Zx and the negative slope value Fx does not change greatly over time, it indicates that the device vibration data has reached a stable state;

[0038] The processing module can determine the development trend of the next vibration amplitude and vibration frequency of the device according to the analysis of the device vibration data collected by the collection module. The processing module analyzes the device vibration data and the falling offset data at the same time, and draws a relationship curve in the coordinate system drawn with the device vibration data and the falling offset data as the x-axis and y-axis, so that the processing module can determine the drug falling position offset caused by vibration when the dosing device doses according to the drawn relationship curve;

[0039] The processing module compares the corresponding drug falling offset data with the pipeline size data. If the drug falling offset data in the pipeline length range is greater than half of the pipeline inner diameter data, an offset adjustment execution signal is generated, and the offset adjustment execution signal is transmitted to the execution module. If the drug falling offset data in the pipeline length range is less than or equal to half of the pipeline inner diameter data, there is no abnormality, and no operation is performed. The pipeline size data includes pipeline length data and pipeline inner and outer diameter data.

[0040] A humidity normal interval and a humidity abnormal interval are set up, and the device humidity data at the same time transmitted by the collection module is subjected to a de-extreme value mean value operation to obtain a device humidity mean value. Then, the device humidity mean value is compared with the humidity normal interval and the humidity abnormal interval. After the device humidity mean value belongs to a certain interval, the count of the interval is increased by one. After the comparison is completed, the counts of the humidity normal interval and the humidity abnormal interval are obtained as normal count value Sz and abnormal count value Sy, respectively. If Sz is greater than or equal to Sy, and Sy is not equal to zero, a local dehumidification execution signal is generated, and the local dehumidification execution signal is transmitted to the execution module. If Sz is greater than Sy, and Sy is equal to zero, there is no abnormality, and no operation is performed. If Sz is less than Sy, a comprehensive dehumidification execution signal is generated, and the comprehensive dehumidification execution signal is transmitted to the execution module.

[0041] The processing module can calculate the moving force data of the medicine in the pipeline according to the difference between the pipeline resistance data and the dosing force data, and calculate the moving speed of the medicine in the pipeline according to the pipeline size data, and determine when the medicine flows out from the horizontal position of the pipeline;

[0042] The execution module receives the execution signal of the processing module, obtains the coordinates of the position with larger humidity data after receiving the local dehumidification execution signal, starts the electric heating sheet at the corresponding position, and performs the drying operation on the local position; after receiving the comprehensive dehumidification execution signal, all electric heating sheets are started to perform the drying operation on all positions; after receiving the offset adjustment execution signal, the corresponding mechanical parts are controlled to adjust the falling offset of the medicine;

[0043] In the prior art, the dosing equipment with automatic metering dosing function only detects the amount of added medicine when performing the dosing operation, and the amount of medicine lost during the adding process cannot be obtained, so that the actual amount of added medicine is less than the detected added amount, the automatic metering function of the dosing equipment is inaccurate, and the effect of the dosing medicine is affected;

[0044] Through the processing and analysis of the equipment vibration data and the equipment humidity data by the processing module, the vibration trend of the equipment can be judged, the falling deviation of the medicine caused by the vibration when the medicine is discharged from the position of the inner tube 2 can be calculated in advance, the execution module can perform the execution preparation in advance, and the execution module can perform the drying operation on the area with larger equipment humidity in advance according to the analysis of the equipment humidity data by the processing module, so that the medicine will not be damp and adhered when passing through the humidity area during the adding process, and the added medicine is prevented from changing in nature due to damp and reducing the actual adding amount due to adhesion.

[0049] In the use of the present application, the vibration trend of the equipment can be judged through the processing and analysis of the equipment vibration data and the equipment humidity data by the processing module, the falling deviation of the medicine caused by the vibration when the medicine is discharged from the position of the inner feeding pipe 2 can be calculated in advance, the execution module can perform preparation in advance, and the execution module can perform drying operation in the area with large equipment humidity in advance according to the analysis of the equipment humidity data by the processing module, so that the medicine will not be damp and adhered when passing through the humidity area during the adding process of the medicine, and the added medicine will not change in nature due to damp and will not be reduced in actual adding amount due to adhesion.

[0050] After the medicine falls from the position of the inner feeding tube 2, it deviates due to the vibration caused by the operation of the equipment.
