Description

Technical Field

[0001] The invention relates to the technical field of equipment status monitoring, and in particular to a method and system for monitoring and warning the status of bean shelling equipment. Background Art

[0002] Beans are an important raw material in the food industry, and their shelling process plays a vital role in the processing process. Existing bean shelling equipment is usually designed as a universal machine that can adapt to the shelling of beans of different types and sizes. However, these devices mainly rely on a single parameter for monitoring during operation, such as using a vibration sensor to monitor equipment vibration or a temperature sensor to monitor local temperature changes. Although these methods can capture abnormal information of the equipment to a certain extent, due to the limited monitoring range, they can only provide limited reference to the operating status of the equipment.

[0003] As for the blockage problem that may occur during the operation of the shelling equipment, the existing technology lacks effective real-time monitoring means and cannot provide timely warnings. Especially when the blockage problem is not identified in the early stage, it is very easy to cause the shelling equipment to suddenly stop during operation, which not only increases the operational risk, but also directly affects the continuity and overall efficiency of the production line. In addition, some technical solutions attempt to optimize the performance of the shelling machine by setting mechanical structure parameters, but these improvements often ignore the mutual influence of multi-dimensional data in the dynamic operating environment, resulting in inaccurate judgment of the blockage problem.

[0004] In existing shelling equipment, it is a common problem that it is difficult to accurately identify blockages during the shelling process. This phenomenon is usually accompanied by complex situations such as bean accumulation inside the sheller and reduced operating speed. However, due to the lack of a dynamic comprehensive evaluation model, it is difficult for equipment managers to discover and deal with problems in a timely manner, which may eventually lead to a stagnation of the production line. In addition, the operation of the sheller relies on bearings as core components, and the vibration, temperature and speed parameters of the bearings have an important impact on the overall performance of the equipment. However, existing technologies rarely link blockage problems with bearing status for overall evaluation, and lack a set of scientific and comprehensive status monitoring and early warning methods, resulting in the safety and stability of equipment operation being difficult to ensure. Therefore, how to construct a technical solution that can integrate blockage conditions and bearing status, monitor the equipment operation status in real time through multi-dimensional dynamic parameters, and effectively warn of potential risks and failures has become a key technical problem that needs to be solved in the field of bean shelling equipment.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0062] Embodiment 1

[0063] Please refer to Figure 1 , the present invention provides a method for monitoring and warning the state of bean hulling equipment, including:

[0064] Step 1: Establish a blockage evaluation model according to the target bean variety;

[0065] It should be noted that the target beans refer to the beans that need to be shelled by the shelling machine each time. Generally, the shelling machine can shell different types of beans. In this embodiment, different types of beans need to establish different blockage evaluation models;

[0066] The specific method for establishing the blockage evaluation model according to the type of target beans is as follows:

[0067] AS1: For the target beans of the same type, place the target beans to be shelled each time in the shelling funnel, obtain the weight of the target beans shelled each time, and at the same time, obtain the weight of the shelling funnel in real time during the operation of the shelling machine, and record it as ;

[0068] Specifically, a weight sensor is installed on the shelling funnel of the shelling machine. Place the target beans to be shelled each time in the shelling funnel to obtain the weight of the target beans shelled each time;

[0069] AS2: Then obtain the shelling rate during the shelling process of the shelling machine each time, and record it as R(t);

[0070] AS3: During the operation of the shelling machine, obtain the weight of the target shelled beans in real time, and record it as ;

[0071] It should be noted that: the target shelled beans refer to the beans that have been completely shelled by the shelling machine for the target beans, and are collected through a storage box equipped with a weight sensor, and at the same time, the weight of the target shelled beans is obtained in real time;

[0072] AS4: According to the weight of the shelling funnel obtained in real time each time the shelling rate R(t) during the shelling process of the shelling machine each time, and the weight of the target shelled beans in real time each time establish a blockage evaluation model, and the blockage evaluation model is reflected by the following formula:

[0073]

[0074] Among them, is the result of the blockage evaluation model, represents the functional relationship between time, target bean weight, shelling rate, and the blockage evaluation model;

[0075] It should be noted that in step AS4, by obtaining a large number of recorded data in AS1 - AS3 and conducting experiments, the relationship between the shelling rate of the shelling machine and the target bean weight changing with time can be obtained; through multiple recordings, a blockage evaluation model can be established, and this model can be obtained through existing technical methods 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 weight of the target beans, the shelling rate, and the changes in real-time acquired data, the blockage situation during the shelling process can be accurately evaluated, which can dynamically reflect the operating status of the sheller; in addition, by using a weight sensor and other real-time data recording devices, the model construction process becomes more scientific and rigorous; through the accumulation and analysis of experimental data multiple times, advanced technologies such as machine learning are used to optimize the model, and finally a high-precision prediction of the blockage situation is achieved, providing a stability guarantee for the shelling process;

[0077] Step 2: Determine the blockage fault risk coefficient during the current operation of the sheller according to the blockage assessment model;

[0078] The specific method for determining the blockage fault risk coefficient during the operation of the sheller according to the blockage assessment model is as follows:

[0079] BS1: Obtain the weight of the target beans for the current shelling and the shelling rate during the shelling process of the current sheller, and at the same time determine the duration of the current sheller from startup to the current operation. By using these three parameters as inputs to predict through the blockage assessment model, the weight of the current target shelled beans is evaluated and denoted as ;

[0080] BS2: At the same moment, obtain the weight of the actual target shelled beans and denote it as ;

[0081] BS3: Then determine the blockage fault risk coefficient during the operation of the sheller through the following formula:

[0082]

[0083] Among them, represents the blockage fault risk coefficient, is a dynamic adjustment factor, reflecting the dynamic change trend of the sheller, and , represents the change factor, which is specifically set by professional staff. The longer the running time , the closer the dynamic adjustment factor of the blockage is to 1; represents the allowable error range threshold;

[0084] In this step, the clogging evaluation model combines key parameters such as the real-time target bean weight and hulling rate to dynamically calculate the clogging fault risk coefficient. A dynamic adjustment factor and an error threshold are incorporated into the calculation of the clogging fault risk coefficient, making the evaluation process more adaptable and flexible, and capable of continuous optimization as the hulling machine runs for a longer time. This mechanism realizes early warning of clogging risks, helps operators take intervention measures before clogging occurs, thus effectively reducing the impact of clogging on equipment operation and extending the service life of the equipment.

[0085] Step 3: During the operation of the hulling machine, determine the bearing vibration coefficient, bearing temperature coefficient, and bearing rotation speed coefficient respectively according to the current bearing vibration amplitude, bearing temperature, and bearing rotation. Then, evaluate the overall operating state of the bearing based on the determined bearing vibration coefficient, bearing temperature coefficient, and bearing rotation speed coefficient, and determine the current overall operating state evaluation coefficient of the bearing.

[0086] The specific method of determining the bearing vibration coefficient, bearing temperature coefficient, and bearing rotation speed coefficient respectively according to the current bearing vibration amplitude, bearing temperature, and bearing rotation, and then evaluating the overall operating state of the bearing based on the determined bearing vibration coefficient, bearing temperature coefficient, and bearing rotation speed coefficient to determine the overall operating state evaluation coefficient of the bearing is as follows:

[0087] CS1: Obtain the bearing vibration amplitude during the operation of the hulling machine and record it as , and perform real-time bearing vibration evaluation through the following evaluation function to determine the bearing vibration coefficient:

[0088]

[0089] Among them, and represent the lower limit value and upper limit value of the normal vibration value range during bearing vibration operation;

[0090] CS2: Obtain the bearing temperature during the operation of the hulling machine and record it as , and perform real-time bearing temperature evaluation through the following evaluation function to determine the bearing temperature coefficient:

[0091]

[0092] Among them, and represent the minimum value and maximum value of the normal temperature value range during bearing temperature operation;

[0093] CS3: Then obtain the set parameters of the bearing rotation during the operation of the hulling machine and record it as , and at the same time, obtain the actual parameters of the bearing rotation during the operation in real time and record it as ; Combine and , determine the deviation value of the bearing rotation during the real-time operation , and ; then, evaluate the bearing rotation speed in real time through the following evaluation function to determine the bearing rotation speed coefficient:

[0094]

[0095] where represents the lower limit value of the allowable bearing rotation deviation, represents the upper limit value of the allowable bearing rotation deviation;

[0096] CS4: According to the bearing vibration coefficient , the bearing temperature coefficient and the bearing rotation speed coefficient evaluate the overall operating state of the bearing to determine the current overall operating state evaluation coefficient of the bearing:

[0097]

[0098] where represents the overall operating state evaluation coefficient of the bearing, is the weight coefficient, and ;

[0099] It should be noted that: the above-mentioned bearing vibration amplitude is obtained through a vibration sensor fixed on the bearing housing or the support structure near the core area of the bearing. When obtaining the actual parameters of the bearing temperature and bearing rotation during the operation of the hulling machine, they are obtained by installing a temperature sensor and a rotation speed sensor;

[0100] This step comprehensively evaluates the operating state of the bearing. Through the dynamic monitoring of key indicators such as vibration amplitude, temperature, and rotation speed, accurately calculates the bearing vibration coefficient, temperature coefficient, and rotation speed coefficient, and comprehensively obtains the overall operating state evaluation coefficient in combination with the weight model; by collecting data through real-time sensors and comparing them with the standard value range, it can quickly locate the anomalies in the bearing operation and avoid equipment shutdown or damage problems caused by bearing failures;

[0101] Step Four: According to the current blockage fault risk coefficient during the operation of the current hulling machine and the current overall operating state evaluation coefficient of the bearing, monitor and warn the current state of the hulling machine to determine whether a warning message is generated;

[0102] The specific method of monitoring and warning the current state of the hulling machine according to the current blockage fault risk coefficient during the operation of the current hulling machine and the current overall operating state evaluation coefficient of the bearing is:

[0103] DS1: Obtain the risk coefficient of blockage failure during the current operation of the hulling machine and the evaluation coefficient of the overall operation state of the current bearing. Determine the current operation index of the hulling machine through the following stability evaluation model, and the stability evaluation model is reflected by the following formula:

[0104]

[0105] Among them, represents the current operation index of the hulling machine, 、 and represent the stability prediction coefficients;

[0106] DS2: Monitor and give early warning of the current state of the hulling machine according to the current operation index of the hulling machine:

[0107] If , it means that the current state of the hulling machine is within the normal operation range;

[0108] If , it means that the current state of the hulling machine deviates from the normal operation range, and a warning message is generated;

[0109] Among them, is a preset value, which is specifically set by professional staff;

[0110] DS3: Judge whether a warning message is generated. If a warning message is judged, an alarm is issued for notification, otherwise no processing is done;

[0111] In this step, by combining the risk coefficient of blockage failure and the evaluation coefficient of the overall operation state of the bearing, the stability evaluation model is used to dynamically calculate the operation state index of the hulling machine, so as to comprehensively monitor the overall state of the equipment; by clearly defining the index range to define the normal and abnormal operation states, warning messages are generated in real time and alarms are triggered, effectively reducing the risk of sudden failures during the operation of the equipment; this step makes the warning mechanism more intelligent and real-time, ensuring that the hulling machine can respond in time when abnormal situations occur, and guaranteeing the continuity and stability of the production process;

[0112] Step Five: When it is judged that a warning message is generated, display the risk coefficient of blockage failure during the current operation of the hulling machine and the evaluation coefficient of the overall operation state of the current bearing on the control panel, and prompt the operator to check the state of the hulling machine or adjust the process parameters to ensure the smooth operation of the hulling machine.
