Description

Technical Field

[0001] This invention relates to the field of belt conveyor equipment testing technology, and in particular to a method, device, equipment and medium for intelligent mutual inspection of speed measuring wheel and slippage switch. Background Technology

[0002] In port coal loading and unloading operations, belt conveyors are one of the core pieces of equipment, and their operational stability and reliability are crucial. Belt scales and slip switches, as key components ensuring the normal operation of belt conveyors, play a significant role. However, in actual production, damage to these two components is difficult to detect in a timely manner. When a slip switch fails, the belt conveyor loses its ability to monitor slippage faults, potentially leading to serious safety accidents such as belt wear, material spillage and accumulation, and even fires, threatening operational safety and causing significant economic losses. When the speed measuring wheel of the belt scale fails, the scale cannot accurately obtain the belt's running speed, severely affecting measurement accuracy. Currently, inspection of these two components mainly relies on manual inspections and periodic maintenance. This traditional method suffers from problems such as slow response and low detection efficiency, making it difficult to meet the needs of efficient and safe port operations. Therefore, it is urgent to solve the problems of slow detection of damage to the speed measuring wheel and slip switch of the belt scale, as well as the slow response and low detection efficiency of manual inspections and periodic maintenance methods in existing technologies. Summary of the Invention

If the slip switch is faulty, redundant slip protection is implemented during the operation phase of the target belt conveyor based on speed data. If the redundant slip protection mode is not activated, mutual verification is performed between the belt speed data and the slip switch signal during the operation phase of the target belt conveyor to achieve fault early warning. This solves the problems of difficulty in timely detection of damage to the speed measuring wheel and slip switch, slow response of manual inspection and regular maintenance, and low detection efficiency. It enables self-diagnosis of both in the early stage of belt conveyor startup, redundant slip detection based on speed measuring wheel data, and mutual detection and fault early warning between the two, significantly improving the safety and reliability of belt conveyor operation, increasing fault detection and handling efficiency, ensuring the measurement accuracy of the belt scale, and providing support for cost reduction, efficiency improvement, and intelligent upgrading of ports.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are presented in the various embodiments of this application to facilitate a better understanding of the application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0017] To facilitate understanding of the embodiments of this application, the relevant content on belt conveyor slippage fault monitoring will be introduced first.

[0018] In port coal loading and unloading operations, belt conveyors are one of the core pieces of equipment, and their operational stability and reliability are of paramount importance. Belt scales and slip switches, as key components ensuring the normal operation of belt conveyors, play a significant role. However, in actual production, damage to either is difficult to detect in a timely manner. When a slip switch malfunctions, the belt conveyor loses its ability to monitor slippage faults, potentially leading to serious safety accidents such as belt wear, material spillage and accumulation, and even fires, threatening operational safety and causing significant economic losses. When the speed measuring wheel of the belt scale malfunctions, the scale cannot accurately obtain the belt's running speed, severely affecting measurement accuracy. Currently, inspection of these two components mainly relies on manual patrols and periodic maintenance. This traditional method suffers from problems such as slow response and low detection efficiency, making it difficult to meet the needs of efficient and safe port operations.

[0019] To address the technical problems of difficulty in timely detection of damage to the speed measuring wheel and slippage switch in the prior art, as well as the sluggish response and low detection efficiency of manual inspection and regular maintenance, this invention proposes an intelligent mutual inspection method for the speed measuring wheel and slippage switch. The implementation details of the intelligent mutual inspection method for the speed measuring wheel and slippage switch in this embodiment are described below. The following implementation details are provided for ease of understanding and are not essential for implementing this solution.

[0020] Example 1: The intelligent mutual detection method between the speed measuring wheel and the slippage switch in this embodiment can be applied to electronic devices with communication, computing, and data storage capabilities, such as programmable controllers (PLCs) in central control systems. The specific process can be as follows: Figure 1 As shown, it includes: Step 101: Obtain the speed data measured by the belt scale speed measuring wheel of the target belt conveyor and the slippage switch signal.

[0021] In the specific implementation, the central control system PLC obtains the speed data measured by the speed measuring wheel of the ground belt scale through the communication module. At the same time, the PLC program already contains the obtained slippage switch signal, realizing the real-time acquisition of the two data.

[0022] Step 102: During the start-up phase of the target belt conveyor, perform fault detection on the belt scale speed measuring wheel and slippage switch based on the speed data.

[0023] In some cases, the target conveyor startup phase includes the first 30 seconds after the conveyor starts (slippage fault bypass time). By performing fault detection on the belt scale speed measuring wheel and slippage switch based on speed data during the target conveyor startup phase, self-diagnosis (self-testing) of the target conveyor startup phase can be achieved.

[0024] In practice, during the startup phase of the target conveyor belt, the speed measuring wheel can be self-diagnosed based on the acquired data from the ground belt scale speed measuring wheel. Therefore, during the startup phase of the target conveyor belt, fault detection is performed on the belt scale speed measuring wheel and slippage switch based on the speed data, including: prompting a fault in the speed measuring wheel when the speed data is continuously equal to 0 or much less than the speed threshold and the duration reaches the set time threshold.

[0025] In some examples, the speed threshold refers to the speed at which the slippage switch is triggered, specifically a preset percentage of the speed measured during no-load operation, such as 75%. This is merely an example, and this embodiment is not limited to a percentage. In cases where a speed measuring wheel malfunction is indicated, further self-diagnosis of the belt conveyor can be performed in conjunction with other belt conveyor malfunctions (such as high-voltage switchgear malfunctions).

[0026] During the startup phase of the target conveyor belt, the slippage switch can also be self-diagnosed based on the speed measuring wheel data. Therefore, during the startup phase of the target conveyor belt, fault detection of the belt scale speed measuring wheel and slippage switch based on speed data includes: indicating a slippage switch fault when the speed data reaches the speed threshold and the slippage switch signal is abnormal, or when the speed data does not reach the speed threshold and the slippage switch signal is normal. In the case of indicating a slippage switch fault, further self-diagnosis of the conveyor belt can be performed in conjunction with other conveyor belt faults (such as high-voltage cabinet faults).

[0027] In some embodiments, the above self-test process can be performed multiple times, for example, three times. If multiple self-tests indicate a speed measuring wheel malfunction and / or a slippage switch malfunction, the corresponding malfunction is identified to avoid false positives from a single self-test result.

[0028] Step 103: If the slippage switch is faulty, the redundant slippage protection mode is activated during the operation of the target belt conveyor. In the redundant slippage protection mode, slippage protection is performed based on the speed data.

[0029] In some embodiments, in the redundant slip protection mode, slip protection is performed based on speed data, including: if the speed data does not reach the speed threshold, then slip protection is triggered.

[0030] If the self-test during startup indicates a slippage switch malfunction (slippage switch damage or unstable signal), the slippage switch will not function properly. Therefore, after the target belt conveyor starts normally, the speed data of the belt scale speed measuring wheel is used to achieve redundant slippage protection for the belt conveyor.

[0031] Furthermore, the aforementioned intelligent mutual detection method between the speed measuring wheel and the slippage switch also includes: If the slip switch is not faulty, slip protection will still be provided based on the slip switch signal.

[0032] Therefore, based on the self-inspection status during the start-up phase of the target belt conveyor, slippage protection can be implemented regardless of whether the slippage switch is faulty, ensuring belt safety and preventing the risk of losing slippage fault monitoring capability once the slippage switch fails, which could lead to threats to operational safety and economic losses.

[0033] Step 104: If the redundant slippage protection mode is not activated, the belt speed data and slippage switch signal are mutually verified during the operation of the target belt conveyor.

[0034] In some embodiments, during the operation of the target belt conveyor, mutual verification is performed based on belt speed data and slippage switch signal, including: if the speed data reaches the speed threshold and the slippage switch signal is abnormal, indicating a slippage switch malfunction; if the speed data does not reach the speed threshold and the slippage switch signal is normal, indicating a speed measuring wheel malfunction.

[0035] Furthermore, a delay time is set before indicating a slippage switch malfunction or a speed measuring wheel malfunction.

[0036] When the belt conveyor is running normally and the redundant slippage protection is disabled, if the speed data of the belt scale speed measuring wheel reaches the speed threshold, but the slippage switch signal is abnormal, a fault alarm will be output after a set time, indicating that the slippage switch is faulty. If the speed data of the belt scale speed measuring wheel does not reach the speed threshold, but the slippage switch signal is normal, a fault alarm will be output after a set time, indicating that the speed measuring wheel is faulty. In this way, the slippage switch and the belt scale speed measuring wheel can be mutually verified and fault warning can be achieved.

[0037] In this embodiment, during the startup phase of the target conveyor belt, fault detection is performed on the belt scale speed measuring wheel and slippage switch based on speed data. If the slippage switch is faulty, redundant slippage protection is implemented based on speed data during the operation phase of the target conveyor belt. If the redundant slippage protection mode is not activated, fault warning is achieved by cross-checking the belt speed data and slippage switch signal during the operation phase of the target conveyor belt. This solves the problems of difficulty in timely detection of damage to the belt scale speed measuring wheel and slippage switch, slow response of manual inspection and regular maintenance, and low detection efficiency. It enables self-diagnosis of both in the early stage of belt belt belt startup, redundant slippage detection based on speed measuring wheel data, and mutual detection and fault warning between the two, significantly improving the safety and reliability of belt conveyor operation, increasing the efficiency of fault detection and handling, ensuring the measurement accuracy of the belt scale, and providing support for cost reduction, efficiency improvement and intelligent upgrading of ports.

[0038] Example 2: This embodiment provides an application example of the intelligent mutual detection method between the speed measuring wheel and the slippage switch in the foregoing embodiments.

[0039] In practical applications, by collecting real-time speed data of the belt scale speed measuring wheel and the slip switch signal, the PLC program is used to realize the self-diagnosis function of the belt scale speed measuring wheel and the slip switch in the early stage of belt conveyor startup. Based on the redundant slip protection of the belt scale speed measuring wheel and the mutual verification between the two, the status monitoring and fault early warning of the belt scale speed measuring wheel and the slip switch are realized.

[0040] (1) Data Acquisition: The PLC of the central control system acquires the data from the speed measuring wheel of the ground belt scale through the communication module. At the same time, the slippage switch signal is already present in the program, thus realizing the real-time acquisition of the two data points. The speed data measured by the speed measuring wheel of the belt scale and the acquisition of the slippage switch signal are as follows: Figure 2 As shown.

[0041] In addition to collecting data through a communication module, a wireless transmission module can also be considered for data transmission. For example, wireless communication technologies such as Bluetooth and Wi-Fi can be used to transmit the data of the belt scale speed measuring wheel and the slippage switch signal to the central control program, so as to adapt to different field environments and equipment layouts.

[0042] (2) Self-diagnosis of the belt scale speed measuring wheel and slippage switch, such as Figure 3 As shown: For the first 30 seconds after the belt conveyor starts (slippage fault bypass time), the following self-diagnosis is performed: The speed measuring wheel of the ground belt scale is self-diagnosed based on the acquired data: when the belt speed data is continuously equal to 0 or much less than the normal value (speed threshold) and reaches the set time threshold, a speed measuring wheel fault is indicated, and self-diagnosis is performed in conjunction with other belt conveyor faults.

[0043] The slippage switch is self-diagnosed based on the speed measuring wheel data: when the belt speed data does not reach the normal value and the slippage switch has a signal, or when the belt speed data reaches the normal threshold and the slippage switch has no signal, the slippage switch is indicated as faulty, and self-diagnosis is performed in conjunction with other belt conveyor faults.

[0044] By continuously setting a time threshold delay, interference from instantaneous fluctuations can be avoided, thus improving the accuracy of fault detection.

[0045] The above self-diagnosis can be performed multiple times, and the number of times can be set according to actual needs.

[0046] (3) Redundant slippage protection, such as Figure 5 As shown: After the belt conveyor starts normally, if the slip switch is damaged or the signal is unstable (a slip switch fault is indicated after self-test), causing the slip switch to malfunction, slip protection of the belt conveyor can be implemented using the speed measuring wheel data of the belt scale. Taking the BM3 belt conveyor as an example, its normal belt speed is approximately 5.9 m / s. Taking 75% of the normal value, approximately 4.5 m / s, as the speed threshold for slip protection, a program for switching between the slip switch and redundant slip is written, such as... Figure 4 As shown. When the slip switch is damaged or the signal is unstable, causing the slip switch to malfunction, the "SpeedCheckChange" label can be switched to enable slip protection using the speed measuring wheel data of the belt scale, thereby ensuring belt safety.

[0047] In addition to using a fixed percentage of the normal belt speed (e.g., 75%), the speed threshold for redundant slippage protection can also be dynamically set based on the actual operating conditions and historical data of the belt conveyor. For example, by analyzing the operating speed data of the belt conveyor under different loads and ambient temperatures, a threshold model can be established to dynamically adjust the threshold, thereby improving the accuracy and adaptability of redundant protection. For instance, if the belt conveyor frequently operates under heavy loads, the percentage could be set to 65%; if the belt is relatively short, the percentage could be set to 80%.

[0048] (4) Mutual verification and fault warning between the slippage switch and the belt scale speed measuring wheel, such as Figure 6 As shown: The program should include a calibration procedure for the belt scale's speed measuring wheel and slippage switch, establishing a correlation between the speed of the speed measuring wheel and the speed threshold triggered by the slippage switch. When the data from these two parameters deviates from the set speed threshold or exhibits a logical contradiction, the calibration procedure should be triggered, displaying corresponding alarm information, such as... Figure 7 As shown.

[0049] The specific workflow is as follows: When the belt conveyor starts and runs normally, and the redundant slippage protection is not enabled, if the speed measuring wheel data of the belt scale is greater than the speed threshold, but the slippage switch signal is abnormal, after a set time (set duration), a fault alarm is output, indicating that the slippage switch is faulty; if the speed measuring wheel data of the belt scale does not reach the speed threshold, but the slippage switch signal is normal, after a set time (set duration), a fault alarm is output, indicating that the speed measuring wheel is faulty.

[0050] By setting a delay before outputting a fault alarm, false diagnoses caused by momentary fluctuations can be avoided, thus improving the accuracy of fault detection. For example, a delay of 3-5 seconds can be set so that an alarm is output only after the fault condition has persisted for 3-5 seconds, indicating the fault or even halting the machine.

[0051] During the mutual verification process, the set duration can be adjusted according to different belt conveyor models and operating requirements. For example, for belt conveyors with higher operating speeds and higher requirements for fault response, the verification time parameter can be appropriately shortened; for belt conveyors with lower operating speeds and relatively lower requirements for fault response, the verification time parameter can be appropriately extended to reduce the occurrence of false alarms.

[0052] By applying this method to the intelligent mutual detection of the speed measuring wheel and the slippage switch, the following beneficial effects can be achieved: (1) Zero-cost redundancy protection for slippage: Redundancy protection for slippage of belt conveyors is achieved by using the speed measuring wheel data of the belt scale, without the need to install new hardware such as slippage switches. Taking the production of a set of 8 belt conveyors with applicable conditions as an example, the installation cost of each belt conveyor can be reduced by RMB 9,000, for a total saving of about RMB 72,000.

[0053] (2) Shorten downtime and improve economic efficiency: By adopting a dual-mode protection switching function, a three-level response mechanism of "fault self-diagnosis - protection switching - function recovery" is constructed, which reduces the mean time to repair (MTTR) to less than 20% of the traditional handling method. Taking a belt conveyor as an example, the system has an annual failure frequency of 1 time / year. The duration of a single failure under the traditional handling mode is 1 hour, and the total duration of the system's impact is 3 hours. Through the above method, a theoretical capacity increase of 9,000 tons / year can be achieved. Based on the current freight rate of 21 yuan / ton, the annual benefit will increase by 189,000 yuan.

[0054] (3) Prevent equipment from operating with defects and improve equipment safety performance: Adopting a dual-system collaborative working mechanism, through real-time status monitoring and intelligent fault diagnosis technology, the slippage protection function can be quickly switched, solving the problem of protection failure caused by single-point faults, avoiding equipment from operating with defects under abnormal working conditions, and significantly improving the reliability and safety of belt conveyor system operation.

[0055] (4) Improve diagnostic efficiency and ensure belt scale accuracy: A real-time verification and detection system for slippage switch and belt scale speed measuring wheel operation status has been constructed, which has revolutionized the traditional manual inspection mode with a monthly cycle. It can capture potential faults of speed measuring wheel in a timely and accurate manner, effectively avoid measurement deviation caused by abnormal speed measuring wheel, ensure belt scale measurement accuracy, and improve the measurement management level of production process.
