[0002] The function of the belt conveyor is to transport materials over a long distance. However, belt deviation is the most common fault of the belt conveyor during the transportation operation. The belt deviation not only affects production and damages the belt, but also increases the running resistance of the belt when non-flame-retardant belt is used, which may cause mine fire accidents due to belt slip.

[0003] According to Chinese patent application No. CN202311134157.9, an intelligent deviation correction system for a belt conveyor is disclosed. The intelligent deviation correction system comprises a deviation detection device that detects the deviation condition of the conveyor belt in real time; a PLC electric control system that collects the deviation signal of the deviation detection device and the running signal of the belt conveyor, and sends a control instruction to a deviation correction execution mechanism based on the deviation signal and the running signal; and a deviation correction execution mechanism that receives the control instruction of the PLC electric control system and performs deviation correction. The deviation correction is achieved by adjusting the tension of the conveyor belt and adjusting the position of the deviation correction execution mechanism.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figure 1 and Figure 2 This application provides an intelligent deviation correction system, including: a conveyor information acquisition unit, a conveyor belt status analysis unit, a deviation correction analysis unit, a periodic monitoring analysis unit, and a deviation correction information output unit, wherein the above functional units are connected by unidirectional wires.

[0034] The conveyor information acquisition unit is used to acquire the working parameters of the conveyor belt and transmit them to the conveyor belt status analysis unit. The working parameters of the conveyor belt are mainly acquired by sensors installed on both sides of the conveyor. Specifically, the conveyor belt is divided into multiple equal segments, and corresponding misalignment sensors are installed on both sides of the division points. The misalignment sensors collect the parameters of the conveyor belt during its movement.

[0035] The conveyor belt status analysis unit analyzes the acquired conveyor belt operating parameters and judges the working status of the conveyor belt based on these parameters. It also generates conveyor belt correction signals and normal monitoring signals. The specific method for generating these signals is as follows:

[0036] All misalignment sensors on the same side of the conveyor belt are labeled i1, where i1 = 1, 2, ..., j, and j is the number of misalignment sensors. Misalignment sensors on the opposite side of the conveyor belt are labeled i2, and i1 = i2. Next, it is determined whether a misalignment sensor generates a corresponding misalignment signal. If so, a conveyor belt correction signal is generated; otherwise, a normal monitoring signal is generated. Specifically, a normal monitoring signal is generated when none of the misalignment sensors generate a signal. If any misalignment sensor generates a misalignment signal, the system generates a conveyor belt correction signal.

[0037] The generated tape correction signal is then transmitted to the correction and analysis unit, and the generated normal monitoring signal is transmitted to the periodic monitoring and analysis unit.

[0038] The tape deviation correction analysis unit analyzes the acquired tape deviation correction signal. It identifies the deviation sensor that generates the signal and acquires the corresponding deviation amount. Based on this deviation amount, it performs deviation correction analysis and generates deviation correction information. The specific method for generating this information is as follows:

[0039] The deviation sensor for generating the adhesive tape deviation correction signal is obtained and denoted as a target sensor, and the offset corresponding to the target sensor is obtained, and then the offset is compared and analyzed to determine whether the offset reaches a secondary offset monitoring value, and the secondary offset monitoring value indicates that after the adhesive tape deviation correction signal is generated, the adhesive tape continues to deviate, and the corresponding deviation value continues to increase to reach a secondary monitoring corresponding deviation value, when the offset is less than the secondary offset monitoring value, an un-reached signal is generated, otherwise when the offset is greater than the secondary offset monitoring value, a reached signal is generated, and the reached signal and the un-reached signal are analyzed and processed respectively.

[0040] For the reached signal, the secondary offset monitoring value is used as a standard for deviation correction and generating deviation correction information, and for the un-reached signal, the maximum offset corresponding to the deviation sensor is obtained and used as a standard for deviation correction and generating deviation correction information, and then the generated deviation correction information is transmitted to a deviation correction information output unit.

[0041] In combination with actual analysis, if the adhesive tape deviation correction signal appears on the conveyor, the machine is normally working, so when the adhesive tape deviation correction signal appears, the following deviation sensor will also generate the adhesive tape deviation correction signal after the first signal appears, and for different offset conditions, the maximum offset appearing is used to adjust the adhesive tape at the corresponding sensor position.

[0042] The deviation correction information output unit is used to transmit the obtained deviation correction information to the intelligent controller for deviation correction.

[0043] Embodiment two, as embodiment two of the present application, is implemented on the basis of embodiment one, and the difference between embodiment one and embodiment two is that.

[0044] The periodic monitoring and analysis unit is used to analyze the obtained normal monitoring signal, collect and monitor the left and right offsets of the adhesive tape, determine the change of the left and right offsets and generate judgment information, the judgment information includes change normal signal and change abnormal signal, the change abnormal signal is analyzed, the periodic change of the left and right offsets of the adhesive tape is analyzed, and the change increasing analysis signal and the unstable analysis signal are generated according to the periodic change, and the two are transmitted to the self-adaptive analysis unit, and the specific way of analyzing the normal monitoring signal is:

[0045] The deviation sensor data at different positions of the adhesive tape is acquired, and the corresponding left offset and right offset in the deviation sensor data are acquired. Then, the left offset and the right offset are compared with the allowable deviation range, respectively. The allowable deviation range indicates that the offset generated by the adhesive tape during operation is within an acceptable range. The specific value of the allowable deviation range is set by an operator. For example, the allowable deviation range can be [1, 3], and the specific unit is cm. When the left offset and the right offset corresponding to all deviation sensors are within the allowable deviation range, it indicates that the adhesive tape transmission is normal, and a normal change signal is generated. Otherwise, when the left offset or the right offset corresponding to any one group of deviation sensors is not within the allowable deviation range, it indicates that the adhesive tape transmission is abnormal, and an abnormal change signal is generated. The generated normal change signal is transmitted to the deviation correction information output unit. Specifically, only when the data of all deviation sensors is normal, it indicates that the transmission of the adhesive tape is normal. If there is any abnormal data, it indicates that the transmission of the adhesive tape is abnormal.

[0046] Then, the abnormal change signal is analyzed. The changes of the left offset and the right offset in n time periods t are acquired, and the specific value of the time period t is set by an operator. A relationship diagram of the offset and the time period is established, and a judgment is made according to the relationship diagram. When the offset increases in the time period, a large change analysis signal is generated. When the offset is unstable in the time period, an unstable analysis signal is generated. The generated large change analysis signal and unstable analysis signal are transmitted to the adaptive analysis unit.

[0047] Specifically, the change of the offset is determined by establishing a corresponding relationship diagram. In actual work, the adhesive tape will deviate due to external factors during operation. There are two cases of such deviation. Specifically, the offset increases on one side, and the other is a periodic change of first increasing and then decreasing, and then increasing. Different analysis signals are generated for the two cases.

[0048] The adaptive analysis unit is used to process the acquired large change analysis signal and unstable analysis signal. The large change analysis signal is analyzed. According to the change of the inclination angle of the edge straight line of the adhesive tape, a warning analysis is performed and a warning information is generated. The regular analysis signal is analyzed. According to the periodic change of the adhesive tape, a warning is determined and a warning information is generated. The warning information includes a warning signal and a normal signal. The specific way of generating the warning information is:

[0049] The large change analysis signal is analyzed to acquire the edge straight line of the adhesive tape. The edge straight line here indicates the edge line between the adhesive tape and the floor. For example, the edge straight line is shown in FIG. 2. Figure 2The inclination angle corresponding to the edge straight line is acquired at the same time, and the inclination angle is compared with a preset value, and the specific value of the preset value is set by the operator, when the inclination angle is greater than the preset value, a warning signal is generated, otherwise when the inclination angle is less than the preset value, a secondary analysis signal is generated; the preset value is represented as the angle value corresponding to the normal and warning critical point, which is set by the operator according to the past data.

[0050] For the secondary analysis signal, the inclination angle is periodically monitored, and the change of the inclination angle in the time period is judged, when the inclination angle is increased, a warning signal is generated, otherwise when the inclination angle is decreased, a normal signal is generated, and the generated warning signal and normal signal are transmitted to the deviation correction information output unit; specifically, the change of the inclination angle reminds the change of the offset amount corresponding to the adhesive tape, if the inclination angle increases, it means that the offset amount of the adhesive tape increases, in this case, a warning signal is generated, if the inclination angle decreases, it means that the offset amount of the adhesive tape decreases, then a normal signal is generated.

[0051] The unstable analysis signal is analyzed, the change duration corresponding to the unstable change is acquired, and a new time period is established as an analysis period, and the unstable changes in multiple analysis periods are judged, when the unstable change is regular change, a normal signal is generated, when the unstable change is irregular change, a warning signal is generated, and the warning signal generated here indicates that the adhesive tape exists abnormality in the working time of transmission, and needs to be warned and maintained.

[0052] The generated warning information is transmitted to the deviation correction information output unit at the same time.

[0053] The deviation correction information output unit displays the generated warning information to the corresponding operator.

[0054] Embodiment three, as an embodiment of the present application, focuses on the combination of the implementation process of embodiment one and embodiment two.

[0055] Part of the data in the above formula is dimensionless numerical calculation, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0056] The above embodiments are only used to illustrate the technical method of the present application, not to limit it, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the present application.
