[0014] The present application provides an adjustment control method and system for a long belt conveyor, which is used to solve the technical problem in the prior art that when adjusting and controlling the belt conveyor, the counterweight hammer of the long belt conveyor is too large, the counterweight adjustment is inconvenient, and automatic control of the belt tension cannot be achieved, which increases useless power consumption during the adjustment process.

[0015] Embodiment 1

[0016] like Figure 1 As shown, the present application provides an adjustment control method for a long belt conveyor, the method comprising:

[0017] Step S100: collecting and acquiring parameter information of multiple indicators of the belt of the target long belt conveyor to obtain a belt information set;

[0018] Specifically, the present application provides an adjustment and control method for a long belt conveyor. By constructing a model, a parameter information analysis and simulation of a target long belt conveyor is performed to determine the starting tension information and the transmission tension information, and control parameters are generated based on this information to control the device of the target long belt conveyor. As a commonly used industrial conveying equipment, long belt conveyors are widely used in metallurgy, mining and other fields. First, the belt parameter information of the target factory belt conveyor is collected to obtain multiple parameter indicators, including tensile strength, reference force elongation, and breaking elongation. The relevant information is integrated and processed to obtain the belt information set. The acquisition of the belt information set provides basic reference information for the subsequent tensioning control of the target long belt conveyor.

[0019] Step S200: constructing a belt tension control analysis model;

[0020] Specifically, the belt tension control analysis model is constructed. The belt tension control analysis model refers to a virtual model that determines relevant control parameters by simulating and analyzing the parameter index information of the long belt conveyor. The target long belt conveyor will inevitably encounter the problem of belt tightness during its working process. As the load increases, the belt of the target long belt conveyor will stretch to affect the tightness of the belt. Sample belt information sets of multiple belts are collected and used as sample data information. Samples are further divided to obtain sample training sets, test sets and verification sets. Model training, testing and verification are performed on the belt tension control analysis model based on the above sample data to improve the actual fit of the belt tension control analysis model. The construction of the belt tension control analysis model provides an auxiliary tool for information analysis for belt conveyor adjustment.

[0021] Step S300: when starting the target long belt conveyor, inputting the belt information set into the belt tension control analysis model to obtain starting tension information;

[0022] Step S400: inputting the starting tension information into the belt tension mapping relationship to obtain a starting belt tension control parameter, and using the starting belt tension control parameter to control the tensioning device in the target long belt conveyor;

[0023] Specifically, when the target long belt conveyor is started, the belt information set is input into the belt tension control analysis model, and information mapping is performed based on the tensile strength of the belt, the reference force elongation and the breaking elongation. Based on the information mapping result, tension information matching the belt information set is obtained, and the tension information is the tension information when the target long belt conveyor is started. The belt conveyor should be checked for tension multiple times during initial use. Too tight a belt will shorten the service life of the belt and the shaft, so as to ensure proper tension. Further, corresponding tension control parameters are set based on multiple sample tension information to obtain multiple sample tension control parameters, and then the multiple sample tension control parameters are mapped with the multiple sample tension information, and the matching parameter information is marked for subsequent identification and distinction, so as to complete the construction of the belt tension mapping relationship, and the starting tension information is further input into the belt tension mapping relationship, and the starting belt tension control parameters are obtained by information identification. Based on the starting belt tension control parameters, the tensioning device in the target long belt conveyor is controlled to adjust it to the optimal state for subsequent load transmission.

[0024] Step S500: when the cargo is transported by the target long belt conveyor, collecting and obtaining cargo load information;

[0025] Step S600: inputting the belt information set and the cargo load information into the belt tension control analysis model to obtain transmission tension information;

[0026] Step S700: input the transmission tension information into the belt tension mapping relationship to obtain the transmission belt tension control parameters, and use the transmission belt tension control parameters to control the tensioning device in the target long belt conveyor.

[0027] Specifically, when cargo is transmitted based on the target long belt conveyor, the cargo load information is obtained by collecting load information, and the cargo load information includes the weight of the unit cargo and the interval distance between the unit cargo during the transportation of the same batch. The cargo load information and the belt information set are further input into the belt tension control analysis model, and the tension information adapted to the operation of the target long belt conveyor is determined by matching and identifying real-time information, that is, the transmission tension information, and then the transmission tension information is input into the belt tension mapping relationship, the transmission tension information is identified and mapped, and the transmission belt tension control parameters adapted to the transmission tension information are determined, and the tensioning device in the target long belt conveyor is parameterized based on the transmission belt tension control parameters, and then the belt tightness of the target long belt conveyor is adaptively adjusted.

[0028] Furthermore, the acquisition of parameter information of multiple indicators of the belt of the target long belt conveyor, step S100 of the present application also includes:

[0029] Step S110: acquiring the multiple indicators, wherein the multiple indicators include tensile strength, reference force elongation, and elongation at break;

[0030] Step S120: Collect and obtain the tensile strength information, reference force elongation information, and breaking elongation information of the belt of the target long belt conveyor to obtain the belt information set.

[0031] Specifically, during the operation of the long belt conveyor, as the belt's load-bearing capacity changes, the belt will deform and stretch to a certain extent. The greater the load, the greater the degree of deformation. When the load limit is reached, the belt will break. The tensile strength, reference force elongation, elongation at break and other indicators associated with the long belt conveyor are determined, and the belt length, width, transmission rate and other indicators of the target long belt conveyor are further determined. On this basis, parameter information of multiple indicators of the target long belt conveyor is collected to obtain the tensile strength, reference force elongation and elongation at break of the target long belt conveyor, and then the information is integrated to obtain the belt information set. The acquisition of the belt information set lays a solid foundation for subsequent real-time situation analysis.

[0032] Furthermore, if Figure 2 As shown, the construction of the belt tension control analysis model, step S200 of the present application also includes:

[0033] Step S210: collecting and acquiring sample belt information sets of multiple belts to obtain multiple sample belt information sets;

[0034] Step S220: collecting and acquiring the tension information of the plurality of belts when the long belt conveyor is started and when transmitting at different loads, to obtain a plurality of sample tension information;

[0035] Step S230: Using the plurality of sample belt information sets and the plurality of sample tension information as construction data, constructing the belt tension control analysis model.

[0036] Specifically, the tensile strength, the reference force elongation and the breaking elongation of multiple belts are collected, and the belts are further mapped with the index parameter information, and are marked for identification and distinction, and the multiple sample belt information sets are obtained. Multiple levels of loads are determined, and non-slip of the belt when fully loaded is taken as the basic restriction requirement. Based on the multiple sample belt information sets, the tension information of multiple belts when the target long belt conveyor is started and different loads are transmitted is collected to obtain multiple sample tension information. Furthermore, the multiple sample belt information sets and the multiple sample tension information are marked as the same type, and used as construction data to construct the belt tension control analysis model.

[0037] Furthermore, the plurality of sample belt information sets and the plurality of sample tension information are used as construction data to construct the belt tension control analysis model. Step S230 of the present application further includes:

[0038] Step S231: dividing and labeling the constructed data to obtain a training set, a validation set, and a test set;

[0039] Step S232: constructing the belt tension control analysis model based on a feedforward neural network;

[0040] Step S233: using the training set, validation set and test set to perform supervised training, validation and testing on the belt tension control analysis model to obtain the belt tension control analysis model.

[0041] Specifically, the multiple sample belt information sets and multiple sample tension information are used as construction data, and data division and data identification are performed on the construction data to obtain the training set, the verification set and the test set. The belt tension control analysis model is constructed based on the feedforward neural network. There is no intermediate feedback information in the belt tension control analysis model. The training set, the verification set and the test set are input into the belt tension control analysis model. Model training and verification tests are performed to enhance the information completeness of the belt tension control analysis model, improve the fit between the model and actual application, and determine the belt tension control analysis model. Based on the belt tension control analysis model, the real-time belt tension information of the belt conveyor is determined.

[0042] Furthermore, when the target long belt conveyor is started, the belt information set is input into the belt tension control analysis model, and step S300 of the present application further includes:

[0043] Step S310: inputting the belt information set and the starting cargo load information into the belt tension control analysis model to obtain an output result, wherein the starting cargo load information is 0;

[0044] Step S320: Obtain the starting tension information according to the identification information in the output result.

[0045] Specifically, when starting the target long belt conveyor, the starting tension information is determined, and the belt information set is input into the belt tensioning control analysis model. When the belt conveyor is in a stationary state, that is, when the starting cargo load information is 0, the tensile strength, the reference force elongation and the breaking elongation of the target long belt conveyor are matched and the tension information corresponding to the belt information set is determined and the information is marked, the starting tension information is obtained and output, and the control parameters of the target long belt conveyor are further determined based on the starting tension information.

[0046] Furthermore, the starting tension information is input into the belt tension mapping relationship to obtain the starting belt tension control parameter. Step S400 of the present application further includes:

[0047] Step S410: setting different tension control parameters for the plurality of sample tension information to obtain a plurality of sample tension control parameters;

[0048] Step S420: constructing a mapping relationship between the plurality of sample tension information and the plurality of sample tension control parameters to obtain the belt tension mapping relationship.

[0049] Specifically, the starting tension information of the target long belt conveyor is determined, the starting tension information is input into the belt tensioning mapping relationship, and tensioning control parameters are set for the multiple sample tension information, the tensioning control parameters are adjustment parameters for tensioning the belt when the target long belt conveyor operates normally, and the multiple sample tensioning control parameters are obtained. The multiple sample tension information corresponds to the multiple sample tensioning control parameters one by one, and mapping identifications of the multiple sample tension information and the multiple tensioning control parameters are further performed to determine the mapping relationship between the two. Based on the belt tensioning mapping relationship, the real-time tension information of the target long belt conveyor is matched with the control parameters to thereby adjust and control the target long belt conveyor.
