Taking running on a computer terminal as an example, Figure 1 1 is a hardware structure block diagram of a computer terminal of a belt adjustment method according to an embodiment of the present application.

[0025] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the methods in the embodiments of the present application. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, the above-mentioned methods are implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal via a network.

[0026] The transmission device 106 is used to receive or send data via a network.

In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0027] In this embodiment, a belt adjustment method is provided, which is applied to the above-mentioned computer terminal or can also be applied to conveying equipment such as a belt conveyor. Figure 2 : is a flow chart of a belt adjustment method according to an embodiment of the present application, the flow chart includes the following steps:

[0028] Step S202, obtaining pressure data of a first stop roller corresponding to the belt, and obtaining vibration data of the first stop roller, wherein the first stop roller includes: a left stop roller and a right stop roller of the belt, and the belt and the first stop roller are deployed on the same conveying equipment;

[0029] Step S204, determining the running state of the belt according to the pressure data and the vibration data;

[0030] Step S206, adjusting the belt according to the operating status.

[0031] Through the above steps, the pressure data of the first stop roller corresponding to the belt is obtained, and the vibration data of the first stop roller is obtained, wherein the first stop roller includes: a left stop roller and a right stop roller of the belt, and the belt and the first stop roller are deployed on the same conveying equipment; the running state of the belt is determined according to the pressure data and the vibration data; and the belt is adjusted according to the running state. In other words, the running state of the belt can be determined by the pressure data and vibration data of the left and right stop rollers of the belt on the same conveying equipment obtained at the same time, and then the belt can be adjusted according to the running state. Through the above embodiments, the problem of the belt on the belt conveyor being easy to deviate in the prior art is solved, thereby achieving the technical effect of being able to determine the running state of the belt in real time and correct the deviation of the belt in real time.

[0032] In an exemplary embodiment, obtaining the pressure data of the first guard roller corresponding to the belt includes: obtaining the pressure value of the first guard roller at the current moment; determining the pressure increase rate value of the first guard roller through the pressure value; determining the pressure value and the pressure increase rate value as the pressure data, wherein the pressure increase rate value is determined by the pressure value and the pressure value at the moment before the current moment.

[0033] During the operation of the belt conveyor, the pressure on the left and right guard rollers can be continuously monitored by a sensor or pressure gauge installed near the guard rollers, and the pressure value at the current moment (for example, at regular time points such as every second or every minute) can be recorded.

[0034] The pressure growth rate value refers to the rate of change of the pressure value over time, that is, the rate of increase or decrease of the pressure. In order to calculate the pressure growth rate value, the pressure value at the current moment can be compared with the pressure value at the previous moment (that is, the previous monitoring time point). The calculation formula can be: pressure growth rate value = (pressure value at the current moment - pressure value at the previous moment) / (time difference between the current moment and the previous moment).

[0035] By calculating the pressure growth rate value, the dynamic changes of the belt during operation can be more deeply understood, for example, whether the belt is suddenly subjected to greater pressure due to load changes, or whether it is gradually loosening. Finally, the pressure value and the pressure growth rate value are determined as the pressure data.

[0036] Through the above embodiment, the system can obtain real-time feedback on the pressure of the retaining roller, and combined with the subsequent vibration data processing, it can conduct a comprehensive analysis of the running status of the belt, so as to adjust the belt in time to prevent deviation or other failures, and ensure the smooth operation of the conveyor. This mechanism is particularly suitable for the fields of automation and industrial control, and can improve the efficiency and reliability of equipment and reduce manual intervention and maintenance costs.

[0037] In an exemplary embodiment, obtaining vibration data to which the first stop roller is subjected includes: obtaining the vibration displacement of the first stop roller at a current moment, and obtaining the velocity and acceleration corresponding to the vibration displacement; and determining the vibration displacement, the velocity and the acceleration as the vibration data.

[0038] Vibration displacement refers to the displacement change of the first roller relative to its static position when vibrating, which can be measured by accelerometers or vibration sensors, which can be installed near the first roller to capture its vibration state in real time. Velocity is the rate at which the vibration displacement of the first roller changes over time, while acceleration is the rate of change of velocity over time, that is, the acceleration value when the roller vibrates. Velocity and acceleration data can also be collected by vibration sensors, or derived from displacement data through subsequent data processing. These data can provide the dynamic characteristics of the vibration of the roller, helping to determine whether the vibration is continuous, periodic or instantaneous, as well as the intensity and frequency of the vibration.

[0039] After obtaining the vibration displacement, velocity and acceleration, these data are integrated to form a complete set of vibration data. The advantage of this is that the vibration state of the guard roller can be comprehensively evaluated from multiple dimensions, and then the operation condition of the belt can be analyzed. For example, if the values ​​of vibration displacement, velocity and acceleration are beyond the normal range, it may indicate that the belt is deviating or some parts of the conveyor are worn or loose.

[0040] By real-time monitoring and analysis of the vibration data of the retaining roller, possible problems encountered in the operation of the belt conveyor, such as deviation, wear or imbalance, can be discovered and solved in a timely manner, which is of great significance for ensuring the stable operation of the conveyor and extending its service life. In addition, this data can also be used to optimize the design and operating parameters of the conveyor, thereby improving its efficiency and performance. In the field of industrial automation and maintenance, this monitoring and analysis method is a common means to ensure the reliable operation of equipment.

[0041] In an exemplary embodiment, the running state of the belt is determined based on the pressure data and the vibration data, including at least one of the following: when the deviation between the first data and the second data meets a preset condition, the running state is determined to be a deviation state, wherein the first data is the target data of the left guard roller, and the second data is the target data of the right guard roller, and the target data includes one of the following: the pressure data, the vibration data; when any one of the first data and the second data is higher than the alarm threshold, the running state is determined to be a pending alarm state.

[0042] This embodiment describes how to use the pressure data and vibration data of the first belt guard roller (the left guard roller and the right guard roller) to determine the running state of the belt, focusing on identifying the deviation and the alarm state.

[0043] Specifically, the logic for determining the deviation state is as follows: Compare the deviation between the first data and the second data: The first data and the second data here refer to the pressure data or vibration data of the left and right guard rollers at a specific moment. The system continuously monitors these data and calculates the deviation between them. For example, by calculating the difference between the pressure values ​​or vibration displacements of the two guard rollers.

[0044] Preset conditions: Preset conditions refer to the system's use of experience or pre-set criteria to determine whether the deviation state means that the belt is at risk of deviation. This usually involves a threshold, that is, when the difference between the pressure or vibration data of the two rollers exceeds the deviation threshold, the system will determine that the belt may be in a deviation state.

[0045] Alarm threshold: The alarm threshold is another pre-set indicator used to determine whether the data of the retaining roller is abnormal. This can be an absolute value, such as pressure or vibration displacement exceeding a certain value, or deviation from the average or standard value exceeding a certain percentage.

[0046] Determine the state to be alarmed: If during the monitoring period, any target data (pressure or vibration data, or any sub-data in pressure or vibration data, such as pressure value in pressure data) of the left or right retaining roller exceeds the alarm threshold, the system will mark the current operating state as "state to be alarmed" even if the belt has not obviously deviated. This indicates that there is a potential problem with the belt conveyor, which may involve wear of the retaining roller, uneven load or other mechanical failures, requiring further inspection and possible maintenance.

[0047] Through the above logic, the system can monitor the operating status of the belt conveyor in real time, not only providing correction instructions when the belt is obviously deviated, but also issuing early warnings before potential problems worsen, thereby improving the operating efficiency and safety of the equipment and reducing downtime and maintenance costs caused by unforeseen failures. This state monitoring and anomaly detection method is widely used in the fields of industrial automation and equipment maintenance, and helps to improve the intelligent management level of production lines.

[0048] In an exemplary embodiment, the belt is adjusted according to the operating state, including: when the operating state is a deviation state, the belt is adjusted by a first deviation correcting machine and a second deviation correcting machine deployed on the same conveying equipment, wherein the first deviation correcting machine is deployed at a drop port of the same conveying equipment, and the second deviation correcting machine is deployed at a discharge port of the same conveying equipment; when the operating state is a waiting-for-alarm state, the operating speed of the belt is controlled, and the belt is adjusted according to the operating speed.

[0049] When it is determined that the belt is running in a deviated state, the first and second deviation correcting machines can be activated for adjustment:

[0050] The first deviation corrector and the second deviation corrector are respectively deployed near the feeding port (i.e. feeding point) or the discharging port (i.e. unloading point) of the conveying equipment. The feeding port is the area where the material enters the belt conveyor, and the discharging port is the area where the material leaves the belt conveyor. The deviation corrector is designed to adjust the position of the belt in time when the belt passes through this area so that it returns to the expected center path. It should be noted that the deviation corrector usually includes an adjustment mechanism, such as a roller, a tray or a guide rail, which can apply a certain lateral force when the belt deviates, thereby guiding the belt back to the correct position. The first deviation corrector and the second deviation corrector can work independently or synergistically to ensure that the belt is effectively adjusted in both directions.

[0051] When the belt is detected as being in the pending alarm state, it means that a component of the belt or conveyor may be about to fail, but the belt has not yet significantly deviated. This usually occurs when any of the pressure data or vibration data exceeds the preset alarm threshold. Even in the absence of obvious deviations, this state indicates a potential problem. At this time, the running speed of the belt can be adjusted, which can be achieved by controlling the conveyor motor. Reducing the speed of the belt can reduce the pressure and vibration on the conveyor, thereby buying time for maintenance personnel to check and repair potential problems and avoid failures. Optionally, the running speed can be directly reduced to 0, which stops the belt.

[0052] It should be noted that changing the running speed itself can also help to realign the belt, especially if it is slightly misaligned. By dynamically adjusting the speed of the belt movement, it is sometimes possible to correct the position of the belt and put it back on the intended path, thus preventing further misalignment.

[0053] Therefore, the embodiment of the present application can effectively maintain the normal operation of the belt conveyor by monitoring the running status of the belt in real time and taking corresponding adjustment measures according to different statuses, reducing the maintenance cost and downtime caused by belt deviation or mechanical failure. This state monitoring and automatic adjustment mechanism is an indispensable part of modern industrial automation and equipment management, and helps to improve the efficiency and reliability of the production line.

[0054] In an exemplary embodiment, the method further includes: acquiring a picture of the belt surface in real time by means of an image acquisition device deployed on the same conveying device; and adjusting the angle of a material guide baffle on the same conveying device when it is determined through the picture that the material on the belt is unevenly distributed.

[0055] In order to better understand the process of the above-mentioned belt adjustment method, the above-mentioned belt adjustment method is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0056] The optional embodiment of the present application proposes a device and system for active adjustment and fault warning of belt conveyor deviation, which can be used to implement the above-mentioned belt adjustment method. Specifically, in order to avoid belt deviation, upper and lower vertical rollers of the roller blocking component on the same mounting frame are designed to limit the deviation of the upper and lower belts (one at an interval of 5 meters), and the pressure (equivalent to pressure data) and vibration (equivalent to vibration data) of the left and right rollers are monitored in real time. The pressure (i.e., pressure or pressure value) and vibration (i.e., vibration displacement) are used to judge the force on both sides. The deviation fault and the running state of the belt conveyor equipment are diagnosed according to the displayed pressure, vibration magnitude value (i.e., vibration displacement), numerical acceleration, change trend curve, etc. According to the diagnosis result, the head wheel and tail wheel of the belt are automatically adjusted and centered and the belt is tightened by using the deviation correction actuator (including the first deviation correction machine and the second deviation correction machine), so as to avoid the fault shutdown and damage to the main components caused by the deviation of the belt. At the same time, a real-time material monitoring infrared camera (i.e., image acquisition equipment) is installed to analyze the distribution and surface temperature of the material, and comprehensively judge the trend of the belt deviation and the state of the material. For deviation problems that cannot be solved by automatic deviation adjustment, different levels of alarm limit values ​​are set to provide early warning.

[0057] It should be noted that if Figure 3 As shown, Figure 3 The system diagram of the active deviation adjustment and fault warning of the belt conveyor according to the embodiment of the present application is shown in FIG. Among them, the bottom monitoring device is used for pressure monitoring and vibration monitoring of the belt retaining roller, as well as infrared dual-light camera monitoring of material distribution and surface temperature. The vertical retaining roller mechanism is as follows: Figure 4 As shown; the middle-level comprehensive analysis includes comparative analysis of the pressure and vibration on the left and right sides of the retaining roller, and analysis of the proportion of material distribution points, so as to determine whether the intervention of the actuator and fault warning are needed; the upper level is mainly the establishment of a visual interface to ensure that the current deviation status of the belt conveyor is intuitively displayed while ensuring detectability, predictability and pre-controllability.

[0058] More specifically:

[0059] 1. Bottom-level monitoring device: Advanced detection technology is selected to detect equipment status quantities including pressure and vibration conditions of the left and right guard rollers (i.e., pressure data and vibration data). First, the belt deviation is judged by the pressure value (pressure value), change growth rate value (i.e., pressure growth rate value), and change trend curve. Second, the change curve of the vibration monitoring quantity is drawn by comparing the vibration displacement, speed, and acceleration. An analysis camera (i.e., image acquisition device) is installed for material distribution detection. The distribution of belt material position points is counted by video detection technology. On the one hand, real-time monitoring of materials is carried out. On the other hand, the angle of the material guide baffle is adjusted according to the distribution points of the materials.

[0060] 2. Middle-level comprehensive analysis: According to the detection points arranged by the bottom-level monitoring device, pressure analysis, vibration value analysis and material distribution status analysis of the left and right belt rollers are carried out. By collecting and analyzing the information of the measuring points, the operating status of the equipment (i.e. the same conveying equipment) can be quickly grasped.

[0061] (1) The pressure detection of the left and right belt rollers is mainly aimed at the deviation of the belt. When the pressure detection values ​​and change trends on the left and right sides show obvious deviations, active deviation adjustment is required and a warning signal is given. For example, a deviation correction machine is installed at the head, tail, front of the tensioning guide roller, the drop point and the discharge port. The logic valve group in the program control station is used to extend and retract the piston rod of the angle adjustment cylinder to drive the linkage deviation correction mechanism to deflect in the set direction. At this time, the linear movement direction of the self-aligning roller forms an angle with the movement direction of the belt, and the friction generated between them drives the belt displacement to re-center. When active deviation adjustment is not enough to eliminate the warning caused by deviation or even has a deterioration trend, timely warning and notification of operation and maintenance personnel for manual intervention.

[0062] (2) The vibration monitoring system not only determines the deviation of the belt, but also monitors the overall health status of the belt conveyor. It needs to complete the following functions and contents:

[0063] Data acquisition and analysis functions: 1) The system can conduct continuous online vibration monitoring of the unit, and issue an alarm in time for abnormal conditions through the alarm threshold set in the system; 2) Provide graded alarms for equipment status, and different alarm statuses are displayed in different, eye-catching color labels on the software interface; 3) Analyze various waveform parameters: peak value, average value, effective value, peak index, waveform index, pulse index, margin index, kurtosis index; 4) Provide graphs: vibration amplitude (peak value, average value, effective value, peak index, waveform index, pulse index, margin index, kurtosis index); waveform graphs (time domain analysis, frequency domain analysis, trend analysis, envelope analysis, Bode diagram, Nyquist diagram); three-dimensional graphs (three-dimensional time, three-dimensional speed); 5) Provide envelope demodulation spectrum; envelope demodulation spectrum is a demodulation analysis of vibration signals; 6) Support primary integration (velocity), secondary integration (displacement) of vibration measurement point data, and no integration (acceleration) conversion.

[0064] Alarm strategy: 1) Supports absolute value alarm and curve alarm (variable operating condition alarm) to meet the needs of different scenarios; 2) Absolute value alarm: Through the pre-set alarm threshold, it is sent to the data logger, and the system automatically gives the alarm level according to the set alarm threshold; 3) Curve alarm (variable operating condition alarm): The system can set the corresponding alarm curve for the fan operating conditions at different speeds or loads, and alarm and protect the unit according to the specific operating conditions to eliminate the impact of variable conditions on fault prediction.

[0065] (3) Visual inspection and analysis technology mainly uses big data analysis and image recognition processing to monitor the distribution of materials on the belt in real time. When there is obvious uneven distribution, the position of the mechanism needs to be adjusted. If the belt does not deviate when idling, but deviates when running under heavy load, it means that the mineral material is unevenly distributed on both sides of the belt. The uneven distribution of mineral material is mainly caused by incorrect falling direction and position of the mineral material. If the mineral material deviates to the left, the belt will deviate to the right, and vice versa. The surface temperature of the material is monitored by an infrared dual-light camera, which can also be used to determine the condition of the upstream material production equipment.

[0066] 3. Upper-level visual interface display: Through real-time display and online analysis of monitoring status quantities, the current belt deviation status and the overall equipment health status of the belt conveyor are displayed in the most intuitive form, guiding operation and maintenance personnel to analyze and handle faults.

[0067] Therefore, the optional embodiments of the present application can determine the belt deviation failure and the overall vibration of the belt conveyor equipment by monitoring the pressure and vibration of the opposing stop rollers on the left and right sides of the belt; by installing an infrared dual-light (visible light and infrared) camera and introducing visual monitoring technology to perform real-time online monitoring of the belt material distribution, the mechanism position can be adjusted in time to prevent the belt from deviating due to uneven material distribution during operation; in addition, infrared cameras can also monitor material surface temperature information in real time online.

[0068] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0069] The present application also provides a structural block diagram of a belt adjustment device. Figure 5 is a structural block diagram of a belt adjustment device according to an embodiment of the present application; Figure 5 As shown, including:

[0070] An acquisition module 52 is used to acquire pressure data of a first stop roller corresponding to the belt, and acquire vibration data of the first stop roller, wherein the first stop roller includes: a left stop roller and a right stop roller of the belt, and the belt and the first stop roller are deployed on the same conveying device;

[0071] A determination module 54, configured to determine the running state of the belt according to the pressure data and the vibration data;

[0072] The adjustment module 56 is used to adjust the belt according to the operating state.

[0073] Through the above device, the pressure data of the first stop roller corresponding to the belt is obtained, and the vibration data of the first stop roller is obtained, wherein the first stop roller includes: a left stop roller and a right stop roller of the belt, and the belt and the first stop roller are deployed on the same conveying equipment; the running state of the belt is determined according to the pressure data and the vibration data; and the belt is adjusted according to the running state. In other words, the running state of the belt can be determined by the pressure data and vibration data of the left and right stop rollers of the belt on the same conveying equipment obtained at the same time, and then the belt can be adjusted according to the running state.
