Description

Technical Field

[0001] The present invention relates to the technical field of raw material transportation, and particularly to a raw material transportation monitoring system. Background Art

[0002] In industrial production, the transportation link of raw materials is crucial. For example, in the production process of a glass factory, various raw materials such as sandstone, dolomite, soda ash, feldspar, limestone, and mirabilite are used. As Figure 1 shown, these raw materials are fed into the kiln head bin of the combined workshop after batching and mixing, and then made into glass sheets after melting, forming, annealing, and cutting. Broken glass is generated during the cutting section in the glass production process, and this broken glass will be returned to the raw material section and added to the mixture as clinker. Given the huge demand for these raw materials, the unloading, storage, and transportation processes need to be completed by conveying equipment, and these equipment are scattered throughout the production process.

[0003] During the raw material transportation process, conveying equipment such as vibrating feeders, vibrating screens, belt conveyors, and bucket elevators are often used. The existing method is for operators to independently control each piece of equipment, and problems occurring during the operation of the equipment are found through patrol inspections, resulting in low monitoring efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a raw material transportation monitoring system to solve or partially solve the technical problem of low monitoring efficiency of existing conveying equipment.

[0005] The technical solution proposed by the present invention is as follows:

[0006] The present invention provides a raw material transportation monitoring system, including: an electrical system for collecting system operation parameters of the conveying equipment and controlling the operation of the conveying equipment; an integrated control station connected to the electrical system for receiving the system operation parameters, generating an execution instruction based on the system operation parameters, sending the execution instruction to the electrical system to control the operation of the conveying equipment and updating the real-time operation data; and an intelligent platform connected to a number of integrated control stations respectively for obtaining the real-time operation data updated by the integrated control stations and controlling each integrated control station based on the real-time operation data.

[0007] In the raw material transportation monitoring system according to the embodiment of the present invention, the electrical system collects the system operation parameters of the conveying equipment, the integrated control station generates an execution instruction based on the system operation parameters, sends the execution instruction to the electrical system to control the operation of the conveying equipment, realizes the monitoring and production operation of a set of conveying equipment for each integrated control station, and then the intelligent platform centrally manages multiple integrated control stations, and uniformly monitors and manages multiple sets of conveying equipment based on the real-time operation data, eliminating the need for on-site personnel to patrol each conveying equipment, and improving the monitoring efficiency of the conveying equipment.

[0008] Optionally, the electrical system includes sensors and electrical control devices. The sensors are used to collect the system operation parameters of the conveying equipment, and the electrical control devices are used to control the operation of the conveying equipment.

[0009] In this way, the sensors can accurately collect the operation parameters of the conveying equipment, providing accurate data support for subsequent control. The electrical control devices stably control the operation of the conveying equipment according to the received instructions, ensuring the smooth progress of the conveying process.

[0010] Optionally, the electrical system further includes a warning system. The warning system is used to output warning information according to an alarm instruction. Correspondingly, the integrated control station is also used to determine whether to output an alarm instruction to the warning system according to the system operation parameters.

[0011] In this way, the integrated control station judges whether to output an alarm instruction according to the system operation parameters, realizing early warning of equipment failures and reducing the risks of equipment damage and production interruption.

[0012] Optionally, the sensor includes a first proximity switch and a baffle. The baffle is arranged at an eccentric position at one end of the tail pulley of the conveyor belt in the conveying equipment. The first proximity switch is arranged on a bracket below the baffle. The first proximity switch is connected to the integrated control station. When the baffle rotates to the lower side, the first proximity switch generates a first proximity switch signal and sends the first proximity switch signal to the integrated control station. Correspondingly, the system operation parameters include the first proximity switch signal. The integrated control station is also used to start timing after the first proximity switch signal disappears, and output a first alarm instruction to the warning system when the first proximity switch signal is not received again after an interval of a first preset time.

[0013] In this way, through the cooperation of the first proximity switch and the baffle, the operation condition of the tail pulley of the conveying equipment can be accurately monitored, problems such as whether the tail pulley stops rotating or runs smoothly can be detected in time, and intelligent monitoring of conveyor belt breakage can be realized.

[0014] Optionally, the sensor includes a second proximity switch and a third proximity switch. The second proximity switch is arranged at the initial position of a preset reciprocating device, and the third proximity switch is arranged at the working position of the preset reciprocating device. Both the second proximity switch and the third proximity switch are connected to the integrated control station. When the preset reciprocating device is at the initial position, the second proximity switch generates a second proximity switch signal and sends the second proximity switch signal to the integrated control station. When the preset reciprocating device is at the working position, the third proximity switch generates a third proximity switch signal and sends the third proximity switch signal to the integrated control station. Correspondingly, the system operation parameters include the second proximity switch signal and the third proximity switch signal. The integrated control station is also used to start timing after the second proximity switch signal disappears, and output a second alarm instruction to the warning system when the third proximity switch signal is not received after an interval of a second preset time.

[0015] In this method, by respectively arranging the second proximity switch and the third proximity switch at the initial position and the working position of the preset reciprocating motion device, the motion state and position information of the device can be accurately monitored, whether the device is in place can be judged, and the abnormal operation of the device can be quickly responded to, avoiding problems such as production interruption or material accumulation caused by device failures.

[0016] Optionally, the integrated control station is also used to start timing after outputting an opening instruction or a stop instruction to the conveying device. After the timing reaches the corresponding timing value, if the conveying device does not generate the corresponding action, a third alarm instruction is output to the warning system.

[0017] In this method, through timing and instruction response monitoring, the problems of delay or failure in the startup and stop processes of the device can be detected in a timely manner, enhancing the reliability and stability of the entire conveying system.

[0018] Optionally, the intelligent platform includes a database and a processing center. The database is used to store the historical operation data sent by each integrated control station, and the processing center is used to generate the device operation trend chart of each conveying device based on the historical operation data, predict the device aging time based on the operation trend chart, and obtain the historical maintenance effect.

[0019] In this method, by generating the device operation trend chart, it helps the operators and maintenance personnel intuitively understand the operation change trend of the device, predict the device aging time and maintenance requirements in advance, and reasonably arrange the device overhaul and replacement plan.

[0020] Optionally, the processing center is also used to generate the bin level trend chart by using the historical operation data, and overall plan the stock volume in the corresponding areas of each integrated control station based on the bin level trend chart.

[0021] In this method, by generating the bin level trend chart using the historical operation data, it visually presents the stock change situation of each bin, facilitating the operators to overall manage the stock volume in each area, reasonably arrange the replenishment and allocation of materials, and avoid material shortage or backlog.

[0022] Optionally, the intelligent platform also includes a human-machine interaction system. The human-machine interaction system is used to analyze the current trend charts of the belt conveyor and the bucket elevator in the conveying device according to the historical operation data, and adjust the start-stop interval of each conveying device and the discharge amount of the feeder based on the current trend charts.

[0023] In this method, the human-machine interaction system analyzes the operation states of the belt conveyor and the bucket elevator based on the current trend charts, and adjusts the start-stop interval of each conveying device and the discharge amount of the feeder according to the analysis results, which can reduce the no-load operation time of the device and improve the device transportation efficiency.

[0024] Optionally, the intelligent platform further includes a monitoring unit, which is used to monitor the operating status of each conveying device according to the real-time operation data and respond to abnormal operating status in real time.

[0025] In this way, through the real-time monitoring of the operating status of the conveying device, the stable operation of the entire raw material conveying monitoring system is ensured, the production interruption time caused by equipment failures is reduced, and the production efficiency is improved.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

It can be a wireless connection or a wired connection.

[0042] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] In industrial production, the transportation link of raw materials is crucial. The traditional manual inspection method is inefficient and cannot monitor the operation status of equipment in real time, making it difficult to meet the requirements of modern production for efficient and accurate monitoring. In order to manage equipment throughout the entire process of raw material unloading, storage, and transfer, the embodiments of the present invention provide a raw material transportation monitoring system. The embodiments of the present invention are applicable to the monitoring of various raw material transportation processes, especially applicable to the transportation monitoring of glass production raw materials.

[0044] As Figure 2 shown, the embodiments of the present invention provide a raw material transportation monitoring system, including:

[0045] An electrical system is used to collect the system operation parameters of a conveying device and control the operation of the conveying device; an integrated control station is connected to the electrical system and is used to receive the system operation parameters, generate execution instructions based on the system operation parameters, send the execution instructions to the electrical system to control the operation of the conveying device and update the real-time operation data; an intelligent platform is respectively connected to several integrated control stations and is used to obtain the real-time operation data updated by the integrated control stations and control each integrated control station based on the real-time operation data.

[0046] Specifically, the electrical system is an actuator or a sensing mechanism for controlling the operation of the conveying device and is distributed in each production area. The actuator is, for example, a controller for controlling the operation speed of the conveying device. The sensing mechanism is, for example, a current sensor installed on the motor of the conveying device for real-time monitoring of the motor operating current; and a speed sensor installed at key positions of the conveyor belt for detecting the running speed of the conveyor belt.

[0047] Each conveying device is independently divided into a manual mode, a remote mode, and a maintenance mode. The manual mode is to control the operation of the device on-site through electrical control; the remote mode is to let the device enter the automatic control system and the integrated control station controls the start and stop of the device; the maintenance mode is to let the single device enter the shutdown state, and the integrated control station adjusts the subsystem state according to the feedback from other devices, such as reducing or stopping the feeding of the upper-level device, to facilitate the on-site maintenance personnel to handle it and quickly resume the system operation after the handling is completed.

[0048] The integrated control station adopts a Programmable Logic Controller (PLC) to achieve remote control, data acquisition, feedback control, sequence control, etc. of the conveying device through the integrated control station. The integrated control station is closely connected to the electrical system and receives the system operation parameters from the electrical system. These parameters include the current value, the conveyor belt speed value, etc. The integrated control station is built-in with control algorithms and generates execution instructions based on these parameters. For example, when the current value suddenly increases and exceeds the set threshold, it may indicate that the motor is overloaded, and the integrated control station will generate corresponding instructions and send them to the electrical system to control the motor to decelerate or stop running, thereby protecting the device. At the same time, the integrated control station will update the real-time operation data to provide a basis for subsequent monitoring and decision-making.

[0049] The intelligent platform, as the high-level management unit of the system, is connected to multiple integrated control stations. Through the plant-wide industrial network, the database aggregates the data of each integrated control station. The intelligent platform obtains the real-time operation data updated by each integrated control station and realizes the unified monitoring and management of multiple sets of conveying devices through data analysis and processing. For example, the intelligent platform can reasonably allocate production tasks and optimize the production process according to the operation status of each device.

[0050] The raw material conveying monitoring system according to the embodiments of the present invention collects the system operation parameters of the conveying equipment through the electrical system. The integrated control station generates execution instructions based on the system operation parameters, and sends the execution instructions to the electrical system to control the operation of the conveying equipment, so as to realize the monitoring and production operation of a set of conveying equipment for each integrated control station. Then, the intelligent platform centrally manages multiple integrated control stations, and uniformly monitors and manages multiple sets of conveying equipment based on the real-time operation data, eliminating the need for on-site personnel to conduct inspections on each conveying equipment, and improving the monitoring efficiency of the conveying equipment.

[0051] In some embodiments, as Figure 3 shown, the electrical system includes sensors and electrical control equipment. The sensors are used to collect the system operation parameters of the conveying equipment, and the electrical control equipment is used to control the operation of the conveying equipment.

[0052] In one example, the sensors include sensors for realizing blockage detection, deviation detection, pull rope and emergency stop detection, silo level detection, and equipment position detection. These sensors all have high-precision measurement capabilities, and can accurately convert physical quantities into electrical signals, providing a reliable basis for subsequent data processing. The sensors are installed at various positions of the conveying equipment according to a certain layout, comprehensively covering the key operation points of the equipment, ensuring that the collected data can truly reflect the overall operation status of the equipment.

[0053] In one example, the electrical control equipment is used to realize the equipment operation feedback control, on-site equipment module control, equipment operation control, and voltage and current parameter control of the conveying equipment.

[0054] The electrical control equipment takes the integrated control station as the core and presets a variety of control logics. For example, during normal production, the integrated control station controls the conveying equipment to operate stably at a set speed according to the production plan and the current equipment status; when a fault occurs in the equipment, it can quickly execute operations such as emergency stop or adjustment of operation parameters to ensure the safety and continuity of production.

[0055] The embodiments of the present invention can accurately collect the operation parameters of the conveying equipment through the sensors, providing accurate data support for subsequent control. The electrical control equipment stably controls the operation of the conveying equipment according to the received instructions, ensuring the smooth progress of the conveying process.

[0056] In some embodiments, the electrical system further includes a warning system, and the warning system is used to output warning information according to the alarm instruction; correspondingly, the integrated control station is further used to determine whether to output an alarm instruction to the warning system according to the system operation parameters.

[0057] Specifically, the warning system includes various warning devices such as audible and visual alarms and warning lights installed at the site of the conveying equipment, integrated control stations, and intelligent platforms. The audible and visual alarm is installed in a conspicuous position around the conveying equipment. When receiving an alarm instruction, it will emit strong audible and visual signals that can cover the entire production area and can be clearly distinguishable even in a noisy environment; the warning light indicates different levels of alarm information through different colors and flashing frequencies. For example, yellow flashing indicates a minor fault in the equipment, and red constant on indicates a serious fault in the equipment, etc.

[0058] The integrated control station will analyze the system operation parameters in real time. For example, when the current sensor detects that the motor current continuously exceeds 120% of the rated value and lasts for more than the preset 5 seconds, the integrated control station determines that the equipment may have serious faults such as overload, and immediately outputs an alarm instruction to the warning system, triggering the audible and visual alarm and the corresponding warning light to turn on, reminding the on-site personnel to take measures in time.

[0059] The embodiment of the present invention can achieve early warning of equipment faults and reduce the risks of equipment damage and production interruption.

[0060] In some embodiments, as shown in Figure 4 、 Figure 5 and Figure 6 the sensor includes a first proximity switch 3 and a baffle 2. The baffle 2 is arranged at an eccentric position at one end of the conveyor belt tail wheel 1 in the conveying equipment. The first proximity switch 3 is arranged on a bracket 4 below the baffle 2. The first proximity switch 3 is connected to the integrated control station. When the baffle 2 rotates to the lower side, the first proximity switch 3 generates a first proximity switch 3 signal and sends the first proximity switch 3 signal to the integrated control station; correspondingly, the system operation parameter includes the first proximity switch 3 signal. The integrated control station is also used to start timing after the first proximity switch 3 signal disappears, and outputs a first alarm instruction to the warning system when the first proximity switch 3 signal is not received again after an interval of the first preset time.

[0061] Specifically, the baffle 2 is made of magnetic core material, and the first proximity switch 3 is a Hall-type proximity switch. The baffle 2 is fixed at an eccentric position at one end of the conveyor belt tail wheel 1 of the conveying equipment. When the baffle 2 rotates with the conveyor belt tail wheel 1, its position relative to the first proximity switch 3 changes continuously. When the baffle 2 rotates to the lowest position, the rotation signal is converted into a magnetic field signal, and the first proximity switch 3 can detect the approach of the baffle 2, thereby generating a first proximity switch 3 signal. Generally, the distance between the baffle 2 and the first proximity switch 3 when the baffle 2 is at the lowest position is set to be 5 mm to 10 mm, which can not only ensure reliable induction but also avoid false triggering caused by too close a distance.

[0062] During the raw material transportation process, when the baffle 2 rotates to the lower part with the tail wheel, the first proximity switch 3 senses the baffle 2, generates a first proximity switch 3 signal and sends it to the integrated control station. The integrated control station records the signal reception time. If the first proximity switch 3 signal suddenly disappears under normal operating conditions, the integrated control station starts timing. When the timing reaches the first preset time (e.g., 2 seconds) and no signal is received again, the integrated control station determines that the conveyor belt tail wheel 1 may stop rotating or have poor operation, there is a risk of belt breakage, and then outputs a first alarm instruction to the warning system to initiate corresponding alarm measures.

[0063] In the embodiment of the present invention, through the cooperation of the first proximity switch 3 and the baffle 2, the operation condition of the tail wheel of the conveying equipment can be accurately monitored, problems such as whether the tail wheel stops rotating or has poor operation can be discovered in time, and intelligent monitoring of the conveyor belt breakage is realized.

[0064] In some embodiments, as Figure 7 shown, the sensor includes a second proximity switch and a third proximity switch. The second proximity switch is set at the initial position of the preset reciprocating motion device, and the third proximity switch is set at the working position of the preset reciprocating motion device. Both the second proximity switch and the third proximity switch are connected to the integrated control station. When the preset reciprocating motion device is at the initial position, the second proximity switch generates a second proximity switch signal and sends the second proximity switch signal to the integrated control station. When the preset reciprocating motion device is at the working position, the third proximity switch generates a third proximity switch signal and sends the third proximity switch signal to the integrated control station; correspondingly, the system operation parameters include the second proximity switch signal and the third proximity switch signal, and the integrated control station is further configured to start timing after the second proximity switch signal disappears, and output a second alarm instruction to the warning system when the third proximity switch signal is not received after an interval of the second preset time.

[0065] Specifically, the preset reciprocating motion device is a diverter. The second proximity switch and the second proximity switch adopt photoelectric proximity switches.

[0066] The second proximity switch is installed at the initial position of the preset reciprocating motion device, and the third proximity switch is installed at the working position of the device. When the preset reciprocating motion device returns to the initial position, the second proximity switch is triggered to generate a second proximity switch signal; when the preset reciprocating motion device reaches the working position, the third proximity switch is triggered to generate a third proximity switch signal.

[0067] After the integrated control station receives the second proximity switch signal, it records the time when the device is in the initial position and starts monitoring subsequent actions. If the third proximity switch signal is not received within the second preset time (e.g., 10 seconds), it indicates that the pusher device has not reached the working position according to the predetermined program, and there may be mechanical failures or control abnormalities. At this time, the integrated control station outputs a second alarm instruction to the warning system to remind the operator to check and handle in time, avoiding problems such as material accumulation or production interruption caused by the failure of the device to act.

[0068] In the embodiment of the present invention, the second proximity switch and the third proximity switch are respectively arranged at the initial position and the working position of the preset reciprocating action device, which can accurately monitor the action state and position information of the device, judge whether the device is in place, quickly respond to abnormal device actions, and avoid problems such as production interruption or material accumulation caused by device failures.

[0069] In some embodiments, as shown in Figure 8 and Figure 9 The integrated control station is also used to start timing after outputting an opening instruction or a stop instruction to the conveying device. After the timing time reaches the corresponding timing value, if the conveying device does not generate the corresponding action, a third alarm instruction is output to the warning system.

[0070] Specifically, when the integrated control station outputs an opening instruction to the conveying device, the internal timer is started simultaneously. Under normal circumstances, the conveying device should respond within 3 seconds, such as the motor starting and the conveyor belt starting to run. When the integrated control station outputs a stop instruction to the conveying device, the internal timer is started simultaneously. Under normal circumstances, the conveying device should respond within 3 seconds, such as the motor stopping rotating and the conveyor belt stopping running.

[0071] The integrated control station judges whether the device generates the corresponding action by monitoring relevant sensor parameters (such as current change, speed signal, etc.). If the response action of the device is still not detected after the timing reaches the set timing value, the integrated control station judges that there may be abnormal situations such as control loop failures or motor failures in the device, and then outputs a third alarm instruction to the warning system to ensure that device failures can be detected and processed in time.

[0072] In the embodiment of the present invention, through timing and instruction response monitoring, the problems of delay or failure in the start-up and stop processes of the device are detected in time, enhancing the reliability and stability of the entire conveying system.

[0073] As shown in Figure 10As shown, in the embodiments of the present invention, different alarm instructions are divided into important alarms and non-important alarms. For example, the first alarm instruction is an important instruction, and the second alarm instruction is a non-important instruction. After receiving an alarm instruction, if the current alarm instruction is an important alarm instruction, the upper-level device stops running and the conveying process is stopped. If it is a non-important instruction, it is further confirmed whether maintenance is required. If maintenance is required, the current device is controlled to stop running and the operating states of other devices are adjusted.

[0074] In some embodiments, the intelligent platform includes a database and a processing center. The database is used to store the historical operation data sent by each integrated control station, and the processing center is used to generate an equipment operation trend chart for each conveying device based on the historical operation data, predict the equipment aging time based on the operation trend chart, and obtain the historical maintenance effect.

[0075] Specifically, the database uses a large-capacity and highly reliable storage device, which can stably store the historical operation data sent by each integrated control station for a long time. These data include various types of information such as the position signal, current value, speed value, and temperature value of the equipment at different time periods, and are stored in an orderly manner according to the time series, facilitating subsequent query and analysis.

[0076] The processing center uses advanced data analysis algorithms and data visualization technologies. When generating the equipment operation trend chart, the processing center will clean, screen, and statistically analyze the historical data, remove outliers and invalid data, extract key feature points such as the peak value, valley value, and average value of the equipment current, and then generate an intuitive operation trend chart through methods such as curve fitting. Based on these trend charts, using prediction models such as machine learning, combined with the normal aging law of the equipment and past maintenance experience, the equipment aging time is predicted. At the same time, by analyzing the historical maintenance records, the effectiveness of the maintenance measures is evaluated, such as whether the operation stability of the equipment has improved and the failure frequency has decreased after a certain maintenance, so as to obtain the historical maintenance effect and provide a reference for subsequent maintenance decisions.

[0077] In the embodiments of the present invention, by generating the equipment operation trend chart, it helps operators and maintenance personnel intuitively understand the operation change trend of the equipment, predict the equipment aging time and maintenance requirements in advance, and reasonably arrange the equipment maintenance and replacement plans.

[0078] Furthermore, the processing center is also used to generate a silo inventory level trend chart based on the historical operation data, and overall plan the inventory levels in the corresponding areas of each integrated control station based on the silo inventory level trend chart.

[0079] The processing center collects the data of the level sensors of each silo, and these data reflect the real-time height of the materials in the silo. By analyzing the historical level data and considering factors such as the feeding and discharging speed of the materials and the production plan, a trend chart of the silo level is generated. The trend chart takes time as the horizontal axis and the level height as the vertical axis, clearly showing the changing trend of the stock volume in the silo.

[0080] According to the trend chart of the silo level, the operator can intuitively understand the stock situation of each silo. For example, when the level of a certain silo continues to decline and approaches the set minimum level warning line, the operator can arrange the material replenishment in a timely manner; for the silos with sufficient stock, the usage order can be reasonably arranged to optimize the allocation of materials. At the same time, through the overall management of the stock volume of each silo, it is possible to avoid production interruptions caused by material shortages in a certain silo, or resource waste and storage pressure caused by excessive stock.

[0081] In the embodiment of the present invention, the trend chart of the silo level is generated using historical operation data, intuitively presenting the changing situation of the stock in each silo, facilitating the operator to overall manage the stock volume of each area, reasonably arrange the replenishment and allocation of materials, and avoid material shortages or overstocking.

[0082] Furthermore, the intelligent platform further includes a man-machine interaction system, which is used to analyze the current trend charts of the belt conveyor and the bucket elevator in the conveying equipment according to historical operation data, and adjust the start-stop interval of each conveying equipment and the discharging volume of the feeder based on the current trend charts.

[0083] Specifically, the man-machine interaction system displays the current trend charts of the belt conveyor and the bucket elevator in the conveying equipment through an intuitive graphical interface. By observing the change curve of the current, the operator can judge the load situation of the equipment. For example, when it is found that the current of the belt conveyor rises too fast and the peak value is too high at the initial stage of startup, it may indicate that the resistance during equipment startup is large, which may be caused by factors such as material accumulation or insufficient belt tension. Based on this analysis, the operator can adjust the start-stop interval of the belt conveyor through the man-machine interaction system, such as appropriately extending the startup interval time to allow the equipment to have a smoother startup process; at the same time, adjust the discharging volume of the feeder to reduce the load during equipment startup, thereby reducing the no-load running time of the equipment, improving the transportation efficiency of the equipment, and reducing equipment wear and energy consumption.

[0084] In the embodiment of the present invention, the man-machine interaction system analyzes the running states of the belt conveyor and the bucket elevator based on the current trend charts, and adjusts the start-stop interval of each conveying equipment and the discharging volume of the feeder according to the analysis results, which can reduce the no-load running time of the equipment and improve the transportation efficiency of the equipment.

[0085] Furthermore, the intelligent platform further includes a monitoring unit, which is used to monitor the running states of each conveying equipment according to real-time operation data and respond in real time to abnormal running states.

[0086] Specifically, the monitoring unit maintains a real-time connection with the integrated control station through a high-speed communication network, and can obtain the real-time operation data of each conveying device in milliseconds, including key parameters such as the current, voltage, temperature, speed, and position of the device. These data are presented in real time on the interface of the monitoring unit in various forms such as dynamic charts and digital displays, enabling operators to intuitively observe the current operating status of the device.

[0087] When the monitoring unit detects an abnormal operating state, such as a sudden sharp rise in the device temperature, it will immediately initiate a series of response measures. On the one hand, it issues an alarm to notify the operator, attracting attention through methods such as audible and visual alarms and popping up an alarm window; on the other hand, according to the preset emergency handling strategy, it automatically performs some basic protection operations, such as reducing the operating speed of the device and adjusting the parameters of the cooling system, to prevent the further expansion of the fault, ensure the stable operation of the entire raw material conveying monitoring system, reduce the production interruption time caused by equipment failures, and improve production efficiency.

[0088] The embodiment of the present invention ensures the stable operation of the entire raw material conveying monitoring system through real-time monitoring of the operating state of the conveying device, reduces the production interruption time caused by equipment failures, and improves production efficiency.
