Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment condition monitoring technology, specifically to a method and system for condition monitoring and early warning of bean shelling equipment. Background Technology
[0002] As an important raw material in the food industry, the shelling process of beans plays a crucial role in the processing of beans. Existing bean shelling equipment is usually designed as a general-purpose machine, capable of shelling different types and sizes of beans. However, these machines mainly rely on monitoring a single parameter during operation, such as using vibration sensors to monitor equipment vibration or temperature sensors to monitor local temperature changes. While these methods can capture abnormal information about the equipment to some extent, they only provide limited reference to the equipment's operating status due to the limited monitoring range.
[0003] Current technologies lack effective real-time monitoring methods to address potential blockages in dehulling equipment, making timely warnings impossible. This is especially problematic when blockages are not identified in their early stages, easily leading to sudden shutdowns of the equipment. This not only increases operational risks but also directly impacts production line continuity and overall efficiency. Furthermore, some solutions attempt to optimize dehulling machine performance by setting mechanical structure parameters; however, these improvements often overlook the interplay of multi-dimensional data in a dynamic operating environment, resulting in inaccurate assessments of blockage issues.
[0004] In existing bean shelling equipment, the difficulty in accurately identifying blockages during the shelling process is a common problem. This phenomenon is usually accompanied by complex situations such as bean accumulation inside the shelling machine and a decrease in operating speed. However, due to the lack of a dynamic comprehensive evaluation model, equipment managers find it difficult to detect and address the problem in a timely manner, which may ultimately lead to production line shutdowns. Furthermore, the operation of the shelling machine relies on bearings as a core component, and the vibration, temperature, and speed parameters of the bearings have a significant impact on the overall performance of the equipment. However, existing technologies rarely link blockage problems with bearing conditions for overall assessment, lacking a scientific and comprehensive condition monitoring and early warning method, making it difficult to guarantee the safety and stability of equipment operation. Therefore, how to construct a technical solution that can comprehensively assess blockage conditions and bearing conditions, monitor the equipment's operating status in real time through multi-dimensional dynamic parameters, and effectively provide early warnings of potential risks and failures has become a key technical challenge that urgently needs to be solved in the field of bean shelling equipment.

[0061] 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.
[0062] Example 1
[0063] Please see Figure 1 This invention provides a method for monitoring and early warning of the status of bean shelling equipment, including:
[0064] Step 1: Establish a blockage assessment model based on the target bean type;
[0065] It should be noted that the target bean refers to the bean that needs to be shelled by the shelling machine each time. The shelling machine can generally shell different types of beans. In this embodiment, different blockage assessment models need to be established for different types of beans.
[0066] The specific method for establishing a blockage assessment model based on the target bean type is as follows:
[0067] AS1: For target beans of the same type, place the target beans to be shelled in the shelling funnel each time, and obtain the weight of the target beans to be shelled each time. Simultaneously, during the operation of the shelling machine, obtain the weight of the target beans in the shelling funnel in real time and record it as follows. ;
[0068] Specifically, the shelling funnel of the shelling machine is equipped with a weight sensor. The target beans that need to be shelled are placed in the shelling funnel each time, so as to obtain the weight of the target beans to be shelled each time.
[0069] AS2: Next, obtain the shelling rate during each shelling process of the shelling machine and denote it as R(t);
[0070] AS3: During the operation of the shelling machine, the weight of the target shelled beans is acquired in real time and recorded as... ;
[0071] It should be noted that: target shelled beans refer to beans that have been completely shelled by the shelling machine and are collected by a collection box equipped with a weight sensor, while the weight of the target shelled beans is acquired in real time.
[0072] AS4: Based on the real-time acquisition of the target bean weight in the hulling funnel each time. The shelling rate R(t) during each shelling process and the weight of the target shelled beans in each real-time step. A congestion assessment model is established, which is represented by the following formula:
[0073]
[0074] in, For the results of the congestion assessment model, It is expressed as a functional relationship between time, real-time target bean weight in the funnel, real-time target shelled bean weight, shelling rate, and the blockage assessment model;
[0075] It should be noted that in step AS4, by acquiring a large number of recorded data from AS1-AS3 and conducting experiments, the relationship between the shelling rate of the shelling machine and the target bean weight over time can be obtained; through multiple recordings, a blockage assessment model is established, which can be obtained through existing techniques such as regression analysis and machine learning, which will not be elaborated here.
[0076] By establishing a blockage assessment model for different types of beans, taking into account the target bean weight, shelling rate, and real-time data changes, the blockage situation in the shelling process can be accurately assessed, and the operating status of the shelling machine can be dynamically reflected. In addition, the use of weight sensors and other real-time data recording devices makes the model construction process more scientific and rigorous. Through the accumulation and analysis of multiple experimental data, advanced technologies such as machine learning are used to optimize the model, ultimately achieving high-precision prediction of blockage and providing stability assurance for the shelling process.
[0077] Step 2: Determine the blockage failure risk coefficient during the current operation of the deshelling machine based on the blockage assessment model;
[0078] The specific method for determining the blockage failure risk coefficient during the operation of the deshelling machine based on the blockage assessment model is as follows:
[0079] BS1: Obtain the current target bean weight for shelling and the shelling rate of the current shelling machine. Simultaneously, determine the duration of the current shelling machine's operation from startup to current running time. By using these three parameters as input, a congestion assessment model is used to predict and evaluate the current target bean weight for shelling, which is then recorded as... ;
[0080] BS2: At the same time, obtain the actual weight of the target shelled beans and record it as... ;
[0081] BS3: Next, the risk factor for blockage during the operation of the shelling machine is determined using the following formula:
[0082]
[0083] in, This is expressed as the congestion failure risk coefficient. This is a dynamic adjustment factor that reflects the trend of dynamic changes in the shelling machine, and , This is represented as a variation factor, specifically set by professional staff, and the running time. The longer the duration, the greater the dynamic adjustment factor for congestion. The closer to 1; Indicates permission The error range threshold;
[0084] This step uses a blockage assessment model combined with key parameters such as real-time target bean weight and shelling rate to dynamically calculate the blockage failure risk coefficient. The calculation of the blockage failure risk coefficient incorporates dynamic adjustment factors and error thresholds, making the assessment process more adaptable and flexible, and continuously optimizing as the shelling machine runs longer. This mechanism enables early warning of blockage risk, helping operators to take intervention measures before blockage occurs, thereby effectively reducing the impact of blockage on equipment operation and extending equipment life.
[0085] Step 3: During the operation of the shelling machine, determine the bearing vibration coefficient, bearing temperature coefficient, and bearing speed coefficient based on the current bearing vibration amplitude, bearing temperature, and bearing rotation. Then, evaluate the overall operating status of the bearing based on the determined bearing vibration coefficient, bearing temperature coefficient, and bearing speed coefficient, and determine the current overall operating status evaluation coefficient of the bearing.
[0086] The bearing vibration coefficient, bearing temperature coefficient, and bearing speed coefficient are determined based on the current bearing vibration amplitude, bearing temperature, and bearing rotation, respectively. Then, the overall operating state of the bearing is evaluated based on the determined bearing vibration coefficient, bearing temperature coefficient, and bearing speed coefficient. The specific method for determining the overall bearing operating state evaluation coefficient is as follows:
[0087] CS1: Obtain the bearing vibration amplitude during the operation of the shelling machine and record it as... The bearing vibration coefficient is determined in real time using the following evaluation function:
[0088]
[0089] in, and These represent the lower and upper limits of the normal vibration range during bearing operation.

[0091]
[0092] in, and These represent the minimum and maximum values of the normal operating temperature range for the bearing.
[0093] CS3: Next, obtain the setting parameters for the bearing rotation during the operation of the casing machine, and record them as... Simultaneously, it acquires and records the actual parameters of bearing rotation during operation in real time. ; combination and Determine the deviation value of bearing rotation during real-time operation. ,and Next, the bearing speed is evaluated in real time using the following evaluation function to determine the bearing speed coefficient:

[0096] CS4: Based on bearing vibration coefficient Bearing temperature coefficient and bearing speed coefficient The overall operating condition of the bearing is evaluated, and the current overall operating condition evaluation coefficient of the bearing is determined:
[0097]
[0098] in, This is represented as the overall bearing operating condition evaluation coefficient. These are the weighting coefficients, and ;
[0099] It should be noted that the above bearing vibration amplitude is obtained by a vibration sensor fixed on the bearing housing or support structure near the core area of the bearing. When obtaining the actual parameters of bearing temperature and bearing rotation during the operation of the deshelling machine, temperature sensors and speed sensors are installed.
[0100] This step comprehensively assesses the bearing's operating status. Through dynamic monitoring of key indicators such as vibration amplitude, temperature, and speed, the bearing's vibration coefficient, temperature coefficient, and speed coefficient are accurately calculated. Combined with a weighted model, the overall operating status assessment coefficient is derived. By collecting data from sensors in real time and comparing it with standard value ranges, abnormalities in bearing operation can be quickly located, avoiding equipment downtime or damage caused by bearing failure.
[0101] Step 4: Based on the blockage failure risk coefficient and the overall bearing operating status evaluation coefficient during the current operation of the shelling machine, monitor and issue early warnings for the current status of the shelling machine, and determine whether to generate early warning information;
[0102] The specific method for monitoring and issuing early warnings about the current status of the deshelling machine based on the blockage fault risk coefficient and the overall bearing operating status evaluation coefficient during the current operation of the deshelling machine is as follows:
[0103] DS1: Obtain the blockage failure risk coefficient and the overall bearing operating status evaluation coefficient during the current operation of the deshelling machine. The current operating indicators of the deshelling machine are determined through the following stability evaluation model, which is expressed by the following formula:
[0104]
[0105] in, This indicates the current operating status of the shelling machine. , and Represented as stability prediction coefficient;
[0106] DS2: Operating indicators based on the current status of the shelling machine. Monitor and issue early warnings regarding the current status of the shelling machine:
[0107] like This indicates that the current shelling machine is within the normal operating range;
[0108] like This indicates that the current shelling machine is out of normal operating range, and a warning message is generated.
[0109] in, These are preset values; the specific settings will be provided by professional staff.
[0110] DS3: Determines whether a warning message has been generated. If a warning message is detected, an alarm is issued to notify the user; otherwise, no action is taken.
[0111] This step combines the blockage failure risk coefficient and the overall bearing operating status evaluation coefficient, and uses a stability evaluation model to dynamically calculate the operating status indicators of the shelling machine, thereby comprehensively monitoring the overall status of the equipment. By defining the normal and abnormal operating states through clear indicator ranges, early warning information is generated in real time and alarms are triggered, effectively reducing the risk of sudden failures during equipment operation. This step makes the early warning mechanism more intelligent and real-time, ensuring that the shelling machine can respond in a timely manner when abnormal situations occur, and ensuring the continuity and stability of the production process.
[0112] Step 5: When a warning message is generated, the blockage fault risk coefficient and the overall bearing operating status evaluation coefficient during the current operation of the shelling machine will be displayed on the control panel, prompting the operator to check the status of the shelling machine or adjust the process parameters to ensure the smooth operation of the shelling machine.
