Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1 As shown in FIG, the port belt conveyor fault warning and remote diagnosis system based on the Internet of Things includes a cargo transportation monitoring module, a belt conveyor detection module, a belt conveyor transportation monitoring module, an early warning terminal and a database.

[0018] The cargo transportation monitoring module is connected to the belt conveyor detection module, the early warning terminal and the database respectively; the belt conveyor detection module is connected to the belt conveyor transportation monitoring module, the early warning terminal and the database respectively; the belt conveyor transportation monitoring module is connected to the early warning terminal and the database respectively.

[0019] The cargo transportation monitoring module is used to monitor the port belt conveyor working on rainy days in real time, analyze the falling instantaneous pressure value of the port belt conveyor corresponding to the transported cargo, and judge whether the current transported cargo will cause impact damage to the port belt conveyor.

[0020] It should be noted that the weight of the goods is obtained from the transport order corresponding to the goods, and a laser rangefinder is used to obtain the position height of the port belt conveyor corresponding to the current goods to be transported, and the types of goods are parcels or bulk, etc.; the basic status of the port belt conveyor at each drop distance corresponding to the same type of goods is obtained from the database, and the drop distances of the belt conveyor that are not affected by the distance are selected, and the average value of each drop distance is calculated to obtain the average drop distance, which is used as the reference drop distance height.

[0021] As an optional implementation, the analysis obtains the falling instantaneous pressure value of the port belt conveyor corresponding to the transported goods. The specific analysis process is as follows: F1. Obtain the basic information of the port belt conveyor corresponding to the current goods to be transported, where the basic information includes the weight and position height of the goods.

[0022] F2. Compare the cargo to be transported with the cargo types stored in the database. If the cargo to be transported is the same as a cargo type stored in the database, obtain the reference drop distance height for each cargo weight of the cargo. If the cargo weight of the cargo to be transported is the same as a cargo weight corresponding to the cargo, but the height of the cargo to be transported from the port belt conveyor is greater than the reference drop distance height for the port belt conveyor corresponding to the cargo weight, monitor the drop of the cargo to be transported when it falls onto the port belt conveyor, so as to monitor the port belt conveyor working on rainy days in real time.

[0023] As an optional implementation method, the judgment of whether the currently transported goods will cause impact hazards to the port belt conveyor is made by the following specific judgment process: using the pressure sensor corresponding to the port belt conveyor to monitor the landing pressure of the first transported goods that fall, and obtaining the number of corresponding batches of the currently required transported goods, the number of corresponding batches of the currently required transported goods multiplied by the landing pressure corresponding to the first transported goods that fall, and analyzing to obtain the falling instantaneous pressure value of the transported goods corresponding to the port belt conveyor, and comparing the falling instantaneous pressure value of the transported goods corresponding to the port belt conveyor with the corresponding reference landing pressure that the port belt conveyor can withstand. If the falling instantaneous pressure value of the transported goods corresponding to the port belt conveyor is greater than the corresponding reference landing pressure that the port belt conveyor can withstand, it is determined that the currently transported goods will cause impact hazards to the port belt conveyor, and further device inspection of the device corresponding to the port belt conveyor is required.

[0024] It should be noted that the standard force value corresponding to the port belt conveyor is obtained from the corresponding functional specification sheet of the port belt conveyor, and its standard force value is used as the reference landing pressure.

[0025] By conducting real-time monitoring of the port belt conveyor operating on rainy days, the instantaneous pressure value of the port belt conveyor corresponding to the transported goods is analyzed to determine whether it will cause impact damage to the port belt conveyor, thereby ensuring the safe operation of the port belt conveyor, preventing transportation safety risks, and achieving timely fault prevention.

[0026] The belt conveyor detection module is used to obtain the component data corresponding to the current port belt conveyor when the transported goods cause impact damage to the port belt conveyor, analyze the regional conditions of the port belt conveyor's corresponding cargo drop area, and monitor the cargo drop corresponding to the port belt conveyor to determine whether the damage to the port belt conveyor's corresponding cargo drop area has worsened.

[0027] It should be noted that the visual network equipment refers to drone patrol equipment or camera monitoring equipment, etc.; the belt wear data specifically refers to the area of ​​surface scratches or surface holes on the belt, etc.; the belt displacement data refers to the uneven distribution of weight on the belt that is overall biased to one side.

[0028] As an optional implementation method, the component data corresponding to the current port belt conveyor is obtained, and the specific acquisition process is as follows: by real-time monitoring of the component devices corresponding to the area currently subjected to the impact hazard of transported goods, first use the visual network equipment to visually monitor the belt components corresponding to the port belt conveyor, obtain the belt image corresponding to the area currently subjected to the impact hazard of transported goods, and extract the belt feature data from the belt image corresponding to the area currently subjected to the impact hazard of transported goods, including belt wear data or belt displacement data. If the belt wear data or belt displacement data corresponding to the area currently subjected to the impact hazard of transported goods is greater than 0, it is determined that the belt state corresponding to the area currently subjected to the impact hazard of transported goods is damaged, and the same data monitoring and acquisition are performed on the roller corresponding to the area currently subjected to the impact hazard of transported goods.

[0029] The accelerometer is used to monitor and obtain the batch impact force of the roller corresponding to the area currently bearing the impact hazard of transported goods. If the batch impact force of the roller corresponding to the area currently bearing the impact hazard of transported goods is greater than the reference compressive strength value of the roller device corresponding to the port belt conveyor, it is determined that the roller corresponding to the area currently bearing the impact hazard of transported goods has experienced roller skin shedding or body deformation. The device monitoring value of the area currently bearing the impact hazard of transported goods is then obtained, which is the component data corresponding to the current port belt conveyor, including the tension of the elastic component, the damaged surface of the elastic component, the wear area of ​​the rolling device and the depression value of the rolling device.

[0030] As an optional implementation, the analysis of the regional condition of the cargo dropping area corresponding to the port belt conveyor, the specific analysis process is as follows: the component data corresponding to the current port belt conveyor is imported into the belt conveyor device detection model, and the detection value corresponding to the port belt conveyor is output. If the detection value output result corresponding to the port belt conveyor is 1, it is diagnosed that the device components of the cargo dropping area corresponding to the port belt conveyor are slightly damaged, and the corresponding damage maintenance can be performed on the port belt conveyor after the batch of cargo transportation is completed. If the detection value output result corresponding to the port belt conveyor is 0, it is determined that the device components of the cargo dropping area corresponding to the port belt conveyor are severely damaged, and the cargo transportation work must be stopped immediately, and the corresponding damage maintenance of the port belt conveyor must be performed immediately, so as to analyze the regional condition of the cargo dropping area corresponding to the port belt conveyor.

[0031] As an optional implementation, the output obtains the detection value corresponding to the port belt conveyor, and the specific output process is as follows: through the calculation formula:

[0032] The output is the detection value η corresponding to the port belt conveyor, L′ is the set reference elastic component tension, L is the elastic component tension corresponding to the port belt conveyor, T′ is the set reference elastic component damage surface, T is the elastic component damage distribution surface corresponding to the port belt conveyor, U′ is the set reference rolling device wear area, U is the rolling device wear area corresponding to the port belt conveyor, P′ is the set reference rolling device depression value, P is the rolling device depression value corresponding to the port belt conveyor, and B is the set reference device evaluation value.

[0033] It should be noted that the standard elastic component tension under the operation of the port belt conveyor is obtained from the functional specification sheet corresponding to the port belt conveyor and used as the reference elastic component tension; the elastic component damage surface of the port belt conveyor corresponding to each historical transmission is obtained from the database, and the elastic component damage surface corresponding to the port belt conveyor in normal transmission is screened out, and then the average value calculation is performed to obtain the average elastic component damage surface at each historical transmission, which is used as the reference elastic component damage surface; the rolling device wear area of ​​the port belt conveyor corresponding to each historical transmission is obtained from the database, and the rolling device wear area corresponding to the port belt conveyor in normal transmission is screened out, and then the average value calculation is performed to obtain the average rolling device wear area at each historical transmission, which is used as the reference rolling device wear area; the rolling device depression value of the port belt conveyor corresponding to each historical transmission is obtained from the database, and the rolling device depression value corresponding to the port belt conveyor in normal transmission is screened out, and then the average value calculation is performed to obtain the average rolling device depression value at each historical transmission, which is used as the reference rolling device depression value.

[0034] As an optional implementation method, the judgment of whether the damage to the cargo dropping area corresponding to the port belt conveyor is aggravated, the specific judgment process is as follows: when the device components based on the cargo dropping area corresponding to the port belt conveyor are in a slightly damaged state, the cargo dropping area corresponding to the port belt conveyor is continuously monitored based on the visual network equipment and sensors, and by monitoring the landing image of the cargo falling on the port belt, it is observed whether the cargo is in a flat stop or rebounds after falling on the port belt conveyor, and the sensor is used to measure the secondary stamping pressure generated on the port belt conveyor after the cargo rebounds, and the number of cargoes corresponding to the rebound and the stamping pressure corresponding to each rebounded cargo in the batch transported cargo are integrated, and the number of cargoes is multiplied by the stamping pressure corresponding to each rebounded cargo to obtain the secondary pressure corresponding to the cargo rebound.

[0035] Compare the secondary pressure borne by the cargo dropping area of ​​the port belt conveyor with the reference stamping pressure difference corresponding to the cargo dropping area of ​​the port belt conveyor. If the secondary pressure borne by the cargo dropping area of ​​the port belt conveyor is greater than the reference stamping pressure difference corresponding to the cargo dropping area of ​​the port belt conveyor, it is determined that the cargo dropping area of ​​the port belt conveyor has suffered secondary damage and the damage has worsened. If the secondary pressure borne by the cargo dropping area of ​​the port belt conveyor is less than or equal to the reference stamping pressure difference corresponding to the cargo dropping area of ​​the port belt conveyor, it is determined that the cargo dropping area of ​​the port belt conveyor has suffered slight secondary stamping pressure and can be handled in the manner of slight damage. This is used to determine whether the damage to the cargo dropping area of ​​the port belt conveyor has worsened.

[0036] It should be noted that the pressure control difference corresponding to the cargo falling area of ​​the port belt conveyor is: based on the impact force generated by the cargo during the initial drop and the reference pressure resistance value corresponding to the port belt conveyor, the reference pressure resistance value corresponding to the port belt conveyor is subtracted from the impact force generated by the cargo during the initial drop to obtain the acceptable reference pressure difference for the cargo falling area of ​​the port belt conveyor.

[0037] When transported goods cause impact damage to the port belt conveyor, the regional conditions of the port belt conveyor corresponding to the cargo drop area are analyzed, and it is determined whether the damage to the port belt conveyor corresponding to the cargo drop area is aggravated, so as to achieve in-depth and comprehensive analysis of the port belt conveyor, so as to efficiently ensure the safe operation of the port belt conveyor, obtain accurate diagnosis results, and carry out timely abnormal maintenance.

[0038] The belt conveyor transport monitoring module is used to monitor the transportation of the corresponding goods on the port belt conveyor when the goods fall onto the port belt conveyor for transportation, diagnose whether the status of the corresponding goods transportation on the port belt conveyor is qualified, and generate the corresponding abnormal maintenance of the port belt conveyor.

[0039] It should be noted that the friction force corresponding to the current port belt conveyor is obtained using a tribometer, the traction force corresponding to the current port belt conveyor is obtained using a dynamometer, and the slipperiness corresponding to the current port belt conveyor is obtained using a sliding friction tester.

[0040] As an optional implementation method, the monitoring of the transportation of goods corresponding to the port belt conveyor, the specific monitoring process is as follows: based on the visual network equipment, the transmission of batch goods transported on the port belt conveyor is monitored, first, the transmission images corresponding to the batch goods are monitored, and the transmission positions of the batch goods corresponding to each time period are monitored. When the goods in a certain transmission image appear to be piled up or sliding, or the cargo delivery position corresponding to a certain transmission time period of the port belt conveyor is inconsistent with the preset reference delivery position, the transmission data corresponding to the current port belt conveyor is obtained based on the sensor, including friction, traction and slipperiness, and substituted into the calculation formula.

[0041] By calculation formula: The feedback coefficient σ of the port belt conveyor corresponding to cargo transportation is calculated, where d is the number of each transmission period, s is any integer greater than 2, s is the number of transmission periods, M′ is the set reference friction force, and M d is the friction force of the port belt conveyor in the dth transmission period, N′ is the set reference traction force, N d is the traction force of the port belt conveyor in the dth transmission period, K′ is the set reference slipperiness, K d is the slipperiness of the port belt conveyor in the dth transmission period.

[0042] It should be noted that the standard friction and standard traction of the port belt conveyor under normal operation are obtained from the corresponding functional specification sheet of the port belt conveyor and used as the reference friction and reference traction. The slippage of the port belt conveyor corresponding to each historical transmission is obtained from the database, and the slippage corresponding to the port belt conveyor during normal transmission is screened out. The average slippage value calculation is performed to obtain the average slippage, which is used as the reference slippage.

[0043] As an optional implementation manner, the diagnosis of whether the status of the port belt conveyor corresponding to cargo transportation is qualified, and the specific diagnostic process is as follows: the feedback coefficient of the port belt conveyor corresponding to cargo transportation is compared with the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment. If the feedback coefficient of the port belt conveyor corresponding to cargo transportation is greater than the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment, it is determined that the status of the port belt conveyor corresponding to cargo transportation is unqualified and is in the abnormal transportation stage, and corresponding abnormal transportation maintenance is required. If the feedback coefficient of the port belt conveyor corresponding to cargo transportation is less than or equal to the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment, it is determined that the status of the port belt conveyor corresponding to cargo transportation is qualified.

[0044] It should be noted that when it is determined that the port belt conveyor is in a qualified state for cargo transportation, continuous real-time remote monitoring of the port belt conveyor will be performed due to the phenomenon of cargo accumulation or inconsistent positions caused by high humidity in a rainy environment.

[0045] As an optional implementation method, the abnormal maintenance corresponding to the port belt conveyor is generated, and the specific generation process is as follows: when the cargo falling area corresponding to the port belt conveyor is slightly damaged, corresponding minor maintenance measures are generated for the port belt conveyor, basic repairs are performed on the device components of the corresponding damaged area of ​​the port belt conveyor based on the damage, and buffer pads are installed to reduce the impact force of the cargo falling onto the port belt conveyor. If the port belt conveyor is seriously damaged, the damaged device components of the corresponding damaged area of ​​the port belt conveyor are replaced, and corresponding rain shields are installed to reduce the impact of environmental factors, thereby generating the abnormal maintenance corresponding to the port belt conveyor.

[0046] It is used to monitor the transportation of corresponding goods of the port belt conveyor, diagnose whether the status of the corresponding goods transportation of the port belt conveyor is qualified, and generate corresponding abnormal maintenance of the port belt conveyor, thereby improving the cargo transportation efficiency and service life of the port belt conveyor, ensuring the corresponding safe transportation of the port belt conveyor, and enhancing the availability of the port belt conveyor.

[0047] The database is used to store basic information, cargo types, component data, transmission data and parameter feedback coefficients.

[0048] The early warning terminal is used to issue early warning prompts when the transported goods cause impact damage to the port belt conveyor, the damage to the port belt conveyor's corresponding cargo drop area is aggravated, or the port belt conveyor's corresponding cargo transportation status is unqualified.

[0049] The embodiment of the present invention monitors the port belt conveyor corresponding to transmission on rainy days, and then determines whether the pressure generated by the current transported goods on the port belt conveyor exceeds the impact range, and acquires data on the belts and devices corresponding to the impact area to determine whether a fault occurs. At the same time, based on the influence of factors of the current port belt conveyor corresponding to the transportation environment, it determines whether the transportation corresponding to the port belt conveyor is normal, thereby realizing fault pre-monitoring of the port belt conveyor from a comprehensive perspective, thereby performing timely maintenance and prevention of faults and fault risks generated by the port belt conveyor, and ensuring the safety and efficiency of the port belt conveyor transportation. At the same time, the transportation monitoring and device fault diagnosis corresponding to the port belt conveyor are all based on remote implementation, which to a certain extent reduces the energy spent on manual fault diagnosis, reduces manual monitoring errors, and ensures the accuracy of the port belt conveyor fault diagnosis, thereby performing targeted fault maintenance, effectively ensuring the corresponding safe transportation of the port belt conveyor, improving the cargo transportation efficiency and service life of the port belt conveyor, enhancing the availability of the port belt conveyor, and intelligently ensuring the operation safety and efficiency of the port belt conveyor.

If the secondary pressure borne by the cargo dropping area of ​​the port belt conveyor is less than or equal to the reference stamping pressure difference corresponding to the cargo dropping area of ​​the port belt conveyor, it is determined that the cargo dropping area of ​​the port belt conveyor has suffered slight secondary stamping pressure and can be handled in the manner of slight damage. This is used to determine whether the damage to the cargo dropping area of ​​the port belt conveyor has worsened.

8. The port belt conveyor fault early warning and remote diagnosis system based on the Internet of Things as claimed in claim 1 is characterized in that: The monitoring process of the port conveyor belt conveyor corresponding to the transportation of goods is as follows: Based on the visual network equipment, the transmission of batches of goods transported on the port belt conveyor is monitored. First, the transmission images corresponding to the batches of goods are monitored, and the transmission positions of the batches of goods corresponding to each time period are monitored. When the goods in a certain transmission image appear to be piled up or sliding, or the cargo delivery position corresponding to a certain transmission period of the port belt conveyor is inconsistent with the preset reference delivery position, the transmission data corresponding to the current port belt conveyor is obtained based on the sensor, including friction, traction and slipperiness, and substituted into the calculation formula; By calculation formula: The feedback coefficient σ of the port belt conveyor corresponding to cargo transportation is calculated, where d is the number of each transmission period, s is any integer greater than 2, s is the number of transmission periods, M′ is the set reference friction force, and M d is the friction force of the port belt conveyor in the dth transmission period, N′ is the set reference traction force, N d is the traction force of the port belt conveyor in the dth transmission period, K′ is the set reference slipperiness, K d is the slipperiness of the port belt conveyor in the dth transmission period.

9. The port belt conveyor fault early warning and remote diagnosis system based on the Internet of Things according to claim 1 is characterized in that: The specific diagnostic process for diagnosing whether the port belt conveyor is in a qualified state for cargo transportation is as follows: The feedback coefficient of the port belt conveyor corresponding to cargo transportation is compared with the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment. If the feedback coefficient of the port belt conveyor corresponding to cargo transportation is greater than the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment, it is determined that the status of the port belt conveyor corresponding to cargo transportation is unqualified and is in the abnormal transportation stage, and corresponding abnormal transportation maintenance is required. If the feedback coefficient of the port belt conveyor corresponding to cargo transportation is less than or equal to the preset reference feedback coefficient of the port belt conveyor corresponding to cargo shipment, it is determined that the status of the port belt conveyor corresponding to cargo transportation is qualified.

10. The port belt conveyor fault early warning and remote diagnosis system based on the Internet of Things according to claim 1, characterized in that: The abnormal maintenance corresponding to the port belt conveyor is generated, and the specific generation process is as follows: When the cargo falling area of ​​the port belt conveyor is slightly damaged, corresponding minor maintenance measures are generated for the port belt conveyor, basic repairs are performed on the device components of the damaged area of ​​the port belt conveyor based on the damage, and buffer pads are installed to reduce the impact of the cargo falling onto the port belt conveyor. If the port belt conveyor is seriously damaged, the damaged device components of the damaged area of ​​the port belt conveyor are replaced, and corresponding rain shields are installed to reduce the impact of environmental factors, thereby generating the corresponding abnormal maintenance of the port belt conveyor.
