It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0051] The overall concept of this application is to convert the torque detected in real time into the real-time detection of the transport volume, and update the accumulated transport volume in real time through wireless signal transmission, thereby realizing real-time monitoring of the overall transport volume. At the same time, it can realize real-time linkage adjustment of the power of the power drive unit based on the instantaneous changes in the transport volume, so as to achieve the matching of input power and transport volume, thereby achieving the goal of energy saving.

[0052] To enable those skilled in the art to better understand the technical concept, implementation scheme and beneficial effects of the embodiments of this application, detailed descriptions are provided below through specific embodiments.

[0053] Figure 1 This is a schematic diagram of the structure of a conveying system provided in one embodiment of this application. Figure 2 This is a schematic diagram of the structure of an intelligent transport volume detection device provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the intelligent transport capacity detection device of this embodiment is applied to a conveying system, which includes a power unit 11 and a conveying unit 12; the power unit 11 is connected to the conveying unit 12.

[0054] In some examples, the power unit 11 can be a unit that provides power to the entire conveying system, specifically an electric motor, diesel engine, gasoline engine, engine, motor, etc. It is understood that the power unit 11 in this embodiment is not limited to one of the above types, and the power unit 11 can be any device or component that can provide power.

[0055] The power unit 11 transmits power to the conveying unit 12, which in turn drives the transport load, which can be ore, sand, cement, coal, etc.

[0056] The conveying unit 12 can specifically be a conveyor belt, conveyor box, or other component with conveying capabilities.

[0057] In this embodiment, the load transported by the conveying unit 12 is detected in terms of the load's weight or volume.

[0058] The detection device in this embodiment may include a first torque detection module 21 and a data processing module 22, wherein the first torque detection module 21 and the data processing module 22 are communicatively connected.

[0059] The first torque detection module 21 and the data processing module 22 can be connected by a wire to achieve communication, or they can be connected wirelessly to achieve communication.

[0060] In this embodiment, the first torque detection module 21 is used to detect the first torque output by the transmission shaft when the first torque detection module 21 is located between the power unit 11 and the conveying unit 12; the first torque can drive the conveying unit 12 to move.

[0061] In some examples, the first torque detection module 21 is specifically used to detect the deformation of the drive shaft when the first torque detection module 21 is located on the drive shaft between the power unit 11 and the conveying unit; determine the voltage or current corresponding to the deformation based on the deformation and a preset bridge; determine the first torque output by the drive shaft based on the voltage and a preset voltage-torque correspondence; or determine the first torque output by the output shaft of the power unit 11 based on the current and a preset current-torque correspondence.

[0062] The first torque detection module 21 can be made of strain material, specifically a ring structure, which is located on the output shaft of the power unit 11.

[0063] The data processing module 22 in this embodiment is used to receive the first torque detected by the first torque detection module 21, and determine the conveying capacity of the conveying unit 12 based on the first torque.

[0064] Specifically, by pre-calibrating the correspondence between the first torque and the conveying capacity, the conveying capacity of the conveying unit 12 can be determined based on this correspondence when the first torque is detected. The correspondence between the first torque and the conveying capacity can be corrected during the operation of the conveying system to more accurately determine the conveying capacity using the first torque.

[0065] When the first torque is detected, the magnitude of the first torque can be learned in advance through deep learning. After learning through the deep learning model, when the first torque is detected, the load capacity can be directly obtained through the learning model. Simply put, the first driving torque required by the conveying unit 12 in the no-load state is T1, and the first driving torque required in the full-load state is T2. T2 and the transport capacity can be learned through the learning model. Furthermore, the first driving torque TX corresponding to various transport capacity conditions can be learned to obtain the learned model. The data can also be corrected through actual verification. Then, the real-time data of different first torques can be matched and converted into real-time transport capacity data through this model algorithm.

[0066] It is understood that the capacity in this embodiment can be the capacity at a single moment.

[0067] In this embodiment, a first torque detection module 21 and a data processing module 22 are communicatively connected. The first torque detection module 21 detects a first torque, which can drive the conveying unit 12 to move. The data processing module 22 receives the first torque detected by the first torque detection module 21 and determines the conveying capacity of the conveying unit 12 based on the first torque. Since the first torque detection module 21 detects the first torque output by the transmission shaft between the power unit 11 and the conveying unit, and determines the conveying capacity of the conveying unit 12 based on the first torque, it is easier to reduce the error of the conveying capacity detection and improve the accuracy of the conveying capacity detection. In addition, this embodiment provides a new conveying capacity detection method, thereby enriching the conveying capacity detection methods.

[0068] See Figure 2 Another embodiment of this application is basically the same as the above embodiment, except that the detection device in this embodiment may further include: a speed detection module 23 that is communicatively connected to the data processing module 22; the speed detection module 23 is used to detect the rotational speed of the drive shaft and / or the speed of the conveying unit 12.

[0069] In some examples, the speed detection module 23 is an encoder.

[0070] Understandably, when the speed detection module 23 is used to detect the rotational speed of the drive shaft, it needs to be installed on the output shaft of the power unit 11; when it is used to detect the speed of the conveying unit 12, it needs to be installed on the conveying unit 12.

[0071] The number of speed detection modules 23 can be the same as the number of objects detected by the speed detection modules 23. For example, if only the rotational speed of the output shaft of the power unit 11 and the speed of the conveying unit 12 are detected, then the number of speed detection modules 23 can be two.

[0072] In some examples, the speed detection module 23 can be set on the output shaft of the power unit 11 to detect the rotational speed of the output shaft of the power unit 11. It is understood that the transmission shaft in this embodiment can be the output shaft of the power unit.

[0073] The data processing module 22 in this embodiment is used to determine whether the conveying system is in a fault state based on the output of the speed detection module 23 and the first torque.

[0074] It is understandable that the output of the speed detection module 23 is the detected rotational speed of the output shaft of the power unit 11 and / or the speed of the conveying unit 12.

[0075] The data processing module 22 determines whether the conveying system is in a fault state based on the output of the speed detection module 23 and the first torque. That is, it determines whether the conveying system is in a fault state based on the detected rotational speed of the output shaft of the power unit 11 and / or the speed of the conveying unit 12 and the first torque detected by the first torque detection module 21.

[0076] If the value of the first torque detected by the first torque detection module 21 is not zero, and the speed of the output shaft of the power unit 11 and / or the speed of the conveying unit 12 detected by the speed detection module 23 is zero, then the conveying system is in a fault state. The specific unit of the conveying system that is faulty can be determined based on the connection relationship and speed of each unit.

[0077] Specifically, the fault condition may be that there is a first torque on the output shaft of the power unit 11, and the conveying unit 12 (transmission equipment) is stalled or jammed.

[0078] In some examples, the conveying system may also include a drive unit connected to the power unit 11; the data processing module 22 is also used to send a stop command to the drive unit to stop the power unit 11 when the first torque exceeds a preset threshold and at least one of the rotational speed of the drive shaft and the rotational speed of the conveying unit 12 is zero.

[0079] In this embodiment, if the first torque exceeds a preset threshold and at least one of the rotational speed of the drive shaft and the speed of the conveying unit 12 is zero, the data processing module 22 sends a stop command to the drive unit. After receiving the stop command, the drive unit controls the power unit 11 to stop, and then the conveying unit 12 stops working, thereby ensuring the safety of personnel and the conveying system.

[0080] In some examples, the conveying system also includes a drive unit 13, one end of which is connected to the power unit 11 via a first drive shaft 14, and the other end of which is connected to the conveying unit 12 via a second drive shaft 15.

[0081] The transmission unit 13 can be a torque protection device (or torque limiting protection device), a gearbox, a coupling, or other components or assemblies with transmission functions. Among these, while achieving intelligent load detection, the torque protection device can absorb and filter impact loads, providing comprehensive protection for the entire system. The transmission unit can be a gearbox, which can be a speed increaser or a speed decreaser. When the gearbox is a speed decreaser, the speed of the second transmission shaft 15 is less than the output speed of the power unit 11 after passing through the speed decreaser. This increases the torque of the second transmission shaft 15, enabling it to drive the conveying unit 12 with a larger torque, thus allowing the conveying unit 12 to transport more load.

[0082] The transmission unit 13 can be one or a combination of two or more of the following: a torque protection device (or torque limiting protection device), a gearbox, and a coupling. Specifically, the transmission unit 13 can be a combination of a torque protection device and a gearbox, or a combination of a torque protection device, a gearbox, and a coupling.

[0083] The transmission unit can also be in other combinations. As long as the corresponding function can be achieved, any combination is within the protection scope of this application.

[0084] In this embodiment, the speed detection module 23 specifically detects the rotational speed of the first drive shaft 14, the rotational speed of the second drive shaft 15, and / or the speed of the conveying unit 12.

[0085] When detecting the speed of the first drive shaft 14, the speed detection module 23 needs to be installed on the first drive shaft 14; when detecting the speed of the second drive shaft 15, the speed detection module 23 needs to be installed on the second drive shaft 15; when detecting the speed of the conveying unit 12, the speed detection module 23 needs to be installed on the conveying unit 12.

[0086] It is understandable that, depending on the working principle, the speed detection module can be set on the component to be tested, such as the first drive shaft 14, the second drive shaft 15, and / or the conveying unit 12. When the speed detection module obtains the rotational speed through the counting principle, the speed detection module includes a first part and a second part, wherein the first part is set on the component to be tested, and the second part can be set on the housing of the power unit or the housing of the transmission unit.

[0087] In this embodiment, the data processing module 22 is specifically used to send a stop command to the drive unit when the first torque exceeds a preset threshold and at least one of the rotational speed of the first drive shaft 14, the rotational speed of the second drive shaft 15, and the speed of the conveying unit 12 is zero, so as to stop the power unit 11 from working.

[0088] In some embodiments, the conveying system may further include a transmission unit 13, one end of which is connected to the power unit 11 via a first transmission shaft 14, and the other end of which is connected to the conveying unit 12 via a second transmission shaft 15.

[0089] When the first torque detection module 21 is specifically installed on the first drive shaft 14, it is used to detect the torque output by the first drive shaft 14, i.e., the first torque.

[0090] When the first torque detection module 21 is specifically installed on the second drive shaft 15, it is used to detect the torque output by the second drive shaft 15, i.e., the first torque.

[0091] In some embodiments, the detection device further includes: a second torque detection module 24, which is communicatively connected to the data processing module 22;

[0092] The first torque detection module 21, when specifically located on the first drive shaft 14, is used to detect the output torque of the first drive shaft 14, i.e., the first torque; the second torque detection module 24, when located on the second drive shaft 15, is used to detect the output torque of the second drive shaft 15, i.e., the second torque.

[0093] The data processing module 22 is specifically used to receive the first torque detected by the first torque detection module and / or the second torque detected by the second torque detection module, and determine the conveying capacity of the conveying unit based on the first torque and / or the second torque.

[0094] In this embodiment, during use, the first torque detection module 21 and the second torque detection module 24 can serve as backups for each other. If one of the torque detection modules fails, the other torque detection module will be activated, thereby improving the reliability of the detection device.

[0095] When the first torque is received, the conveying capacity of the conveying unit can be calculated based on the first torque; when the second torque is received, since the first torque and the second torque represent the torques of different shafts and are not equal, the equivalent calculation of the conveying capacity of the conveying unit can be achieved based on the second torque.

[0096] To improve the accuracy of the calculation, a first torque and a second torque can be received. The transport volume calculated based on the first torque and the transport volume calculated based on the second torque are taken as the average value of the two transport volumes as the transport volume of the conveying unit.

[0097] As an alternative, another embodiment of this application is basically the same as the above embodiment, except that the detection device in this embodiment may further include: a displacement detection module 25 that is communicatively connected to the data processing module 22;

[0098] In this embodiment, the displacement detection module 25 is used to detect whether at least one of the mass points on the transmission shaft and the conveying unit 12 has relative motion with a designated base point.

[0099] It is understandable that when the displacement detection module 25 detects the object, the sensing component in the displacement detection module 25 can be disposed on the object being detected, and the sensing component in the displacement detection module 25 can be disposed on a designated base point, such as on the housing of the power unit. Specifically, the displacement detection module 25 can be a proximity switch.

[0100] It is understood that, in this embodiment, the designated base point also moves relative to the base point when the object being detected moves relative to the horizontal plane. The position of the designated base point in this embodiment is set according to the location where it can be installed or is convenient for installation and maintenance.

[0101] The data processing module 22 determines whether the conveying system is in a fault state based on the output of the displacement detection module 25 and the first torque. Specifically, it determines whether the conveying system is in a fault state based on whether at least one mass point on the output shaft of the power unit 11 and any mass point on the conveying unit 12 generates relative motion with the designated base point and the first torque detected by the first torque detection module 21.

[0102] If the value of the first torque detected by the first torque detection module 21 is not zero, and the displacement detection module 25 detects that at least one of the mass points on the output shaft of the power unit 11 and the mass point on the conveying unit 12 is in relative motion with the specified base point, then the conveying system is in a fault state. The specific unit of the conveying system that is faulty can be determined based on the connection relationship and relative movement of each unit.

[0103] Specifically, the fault condition may be that there is a first torque on the output shaft of the power unit 11, and the conveying unit 12 (transmission equipment) is stalled or jammed.

[0104] Understandably, if the detection device has two or more torque detection modules, and the first torque detection module fails, another torque detection module can be activated. Based on the torque detected by this module and the output of the displacement detection module, it can also be determined whether the conveying system is in a faulty state.

[0105] In some examples, the conveying system also includes a drive unit; the drive unit is connected to the power unit.

[0106] In this embodiment, the data processing module 22 is used to send a stop command to the drive unit to make the power unit 11 stop working when the first torque exceeds a preset threshold and the output of the displacement detection module 25 is that at least one of the mass points on the drive shaft and the mass points on the conveying unit 12 moves relative to the specified base point.

[0107] In this embodiment, if the first torque exceeds a preset threshold and at least one of the mass points on the output shaft of the power unit 11 and the conveying unit 12 moves relative to the designated base point, the data processing module 22 sends a stop command to the drive unit. After receiving the stop command, the drive unit controls the power unit 11 to stop, thereby ensuring the safety of personnel and the conveying system.

[0108] In some examples, the conveying system also includes a transmission unit 13, one end of which is connected to the power unit 11 via a first transmission shaft 14, and the other end of which is connected to the conveying unit 12 via a second transmission shaft 15.

[0109] The power unit 11, the first drive shaft 14, the transmission unit 13, and the second drive shaft 15 in this embodiment are the same as those described in the previous embodiments, and will not be repeated here.

[0110] In this embodiment, the displacement detection module is specifically used to detect whether at least one of the following particles—any particle on the first drive shaft 14, any particle on the second drive shaft 15, and any particle on the conveying unit—is moving relative to a designated base point.

[0111] It is understood that when the displacement detection module 25 detects the object, the sensing component in the displacement detection module 25 can be disposed on the object being detected, and the sensing component in the displacement detection module 25 can be disposed on a designated base point, such as a component that is stationary relative to the horizontal plane, specifically, such as disposed on the housing of the power unit 11 and / or the housing of the transmission unit 13. Specifically, the displacement detection module 25 can be a proximity switch.

[0112] In this embodiment, the data processing module is specifically used to send a stop command to the drive unit when the first torque exceeds a preset threshold and at least one of the following particles—any particle on the first drive shaft 14, any particle on the second drive shaft 15, and any particle on the conveying unit—is in relative motion with a specified base point, so that the power unit 11 stops working.

[0113] In this embodiment, if the first torque exceeds a preset threshold and at least one of the following particles—any particle on the conveying unit 12, any particle on the first drive shaft 14, and any particle on the second drive shaft 15—moves relative to the horizontal plane, the data processing module 22 sends a stop command to the drive unit. Upon receiving the stop command, the drive unit controls the power unit 11 to stop, thereby stopping the first drive shaft 14, the speed change unit, the second drive shaft 15, and the conveying unit 12, thus ensuring the safety of personnel and the conveying system.

[0114] In some instances, when the conveying system is in a faulty state, the data processing module 22 is also used to record the duration of the fault and / or issue an alarm signal.

[0115] Recording the duration of a fault facilitates the calculation of total throughput over a period of time. Issuing alarm signals can protect personnel and equipment.

[0116] In order to make the total transport volume more accurate over a period of time, in some examples, the first torque detection module 21 is specifically used to detect the first torque output by the output shaft of the power unit 11 at each moment within a specified time period; the data processing module 22 records the fault duration, which is within the specified time period.

[0117] As an optional embodiment, the data processing module is specifically used to receive the first torque detected by the first torque detection module at each moment within a specified time period, and determine the transport capacity of the conveying unit at each moment based on the first torque at each moment; calculate the first total transport capacity of the conveying unit within the specified time period based on the transport capacity of the conveying unit at each moment; determine the second total transport capacity within the fault duration based on the fault duration and the first torque detected within the fault duration; and subtract the second total transport capacity from the first total transport capacity to obtain the actual total transport capacity of the conveying unit within the specified time period.

[0118] The first torque detection module 21 detects the first torque output by the output shaft of the power unit 11 at various moments within a specified time period, and each data processing module 22 correspondingly determines the transport capacity of the first torque delivery unit 12, i.e., the transport capacity at each moment.

[0119] Based on the transport volume of transport unit 12 at each time moment, the first total transport volume of transport unit 12 within a specified time period can be calculated. This can be achieved by integrating the transport volume at each time moment to obtain the total transport volume of transport unit 12 within the specified time period, i.e., the first total transport volume. Alternatively, the average transport volume per unit time can be calculated from the transport volume at each time moment to obtain the total transport volume of transport unit 12 within the specified time period, i.e., the first total transport volume.

[0120] During the fault duration, the transport volume of the conveying unit 12 is zero, that is, the actual transport volume is zero. During the fault duration, the first torque detection module 21 detects the first torque, and the transport volume can be obtained through the first torque. Based on the fault duration and the first torque detected during the fault duration, the second total transport volume during the fault duration is determined. Specifically, the transport volume during the fault duration, i.e., the second total transport volume, can be determined based on the first torque detected during the fault duration and the correspondence between torque and transport volume, or the transport volume during the fault duration, i.e., the second total transport volume, can be obtained based on a pre-learned learning model.

[0121] To obtain a more accurate actual total transport volume, the transport volume that can be obtained through the first torque during the fault duration needs to be removed, that is, the first total transport volume minus the second total transport volume, to obtain the actual total transport volume of the conveying unit 12 within the specified time period, thereby avoiding misreading of the total transport volume.

[0122] It is understood that the fault duration in this embodiment includes the specified time period.

[0123] As another optional embodiment, the data processing module 22 is specifically used to receive the first torque detected by the first torque detection module 21 at each moment within the first effective time period, and determine the transport capacity of the conveying unit 12 at each moment based on the first torque at each moment; and obtain the actual total transport capacity of the conveying unit 12 within the effective time period based on the transport capacity of the conveying unit 12 at each moment.

[0124] In this embodiment, the first effective time period is the time period within the specified time period after removing the duration of the fault.

[0125] In this embodiment, when calculating the actual total transport volume, the fault time can be removed from the specified time, and the other times other than the fault time and the corresponding first torque can be used to obtain the actual total transport volume of the conveying unit 12 within the first effective time.

[0126] In some cases, if the conveyor unit 12 uses an output belt, chain, or other conveying method, and a belt or chain breaks, the data processing module 22 will issue an alarm signal. The transport volume at the time the alarm signal is issued and the transport volume after that time will be considered abnormal. This part of the transport volume needs to be removed from the transport volume to obtain a more accurate total transport volume.

[0127] Correspondingly, in some examples, the first torque detection module 21 is specifically used to detect the first torque output by the output shaft of the power unit 11 at each moment within a specified time period; the data processing module 22 issues an alarm signal at the first moment within the specified time period; the data processing module 22 is specifically used to receive the first torque detected by the first torque detection module 21 at each moment within the specified time period, and determine the transport capacity of the conveying unit 12 at each moment based on the first torque at each moment; calculate the first total transport capacity of the conveying unit within the specified time period based on the transport capacity of the conveying unit 12 at each moment; determine the second total transport capacity within the second effective time period based on the second effective time period from the first moment to the second moment and the first torque detected within the second effective time period; the second moment is within the specified time period and is the moment when the alarm signal is released; the first total transport capacity minus the second total transport capacity yields the actual total transport capacity of the conveying unit 12 within the specified time period.

[0128] In this embodiment, the first total transport volume is calculated based on the first torque at each specified time. Then, based on each time between the time when the alarm signal is issued and the end time of the specified time period, and the first torque corresponding to each time, the second total transport volume is obtained. The second total transport volume is an abnormal transport volume and needs to be removed from the first total transport volume.

[0129] As an alternative implementation, the data processing module 22 is specifically used to receive the first torque detected by the first torque detection module 21 at each moment within the third effective time period, and determine the transport capacity of the conveying unit 12 at each moment within the third effective time period based on the first torque at each moment within the third effective time period; and obtain the actual total transport capacity of the conveying unit 12 within the third effective time period based on the transport capacity of the conveying unit 12 at each moment within the third effective time period.

[0130] In this embodiment, the third valid time period is the time period from the start time of the specified time period to the first time period.

[0131] In some examples, the conveying system also includes a drive unit connected to the power unit 11; the data processing module 22 is further configured to determine a drive strategy based on the first torque and send the drive strategy to the drive unit so that the drive unit adjusts the output power of the power unit 11 according to the drive strategy.

[0132] When the data processing module 22 obtains the first torque, it can determine the driving strategy of the driving power unit 11 according to the pre-set correspondence between torque and power or torque and current, and send the driving strategy to the driving unit. After receiving the driving strategy, the driving unit drives the power unit 11 according to the driving strategy, thereby adjusting the output power of the power unit 11, thereby achieving dynamic balance between power output power and load, and realizing energy saving.

[0133] This embodiment enables real-time torque detection of the transmission equipment, detection of the equipment's carrying capacity, safe operation of the equipment, adjustment of the equipment's output power, stable safe operation of the equipment, prediction of equipment failure, and linkage protection of related components. For example, a safety upper limit is set for the transmitted torque; if this safety value is exceeded, the equipment drive component will trigger a power-off protection for the power unit 11. It also provides a good solution for intelligent closed-loop control. The real-time detection of the first torque corresponds to the real-time changes in the power output unit, which can issue real-time commands to achieve effective output power balance.

[0134] Specifically, the total transport volume can be obtained by accumulating the transport volume. At the same time, the output of force (torque) can be realized through speed sensors and other technical means, but the judgment of special working conditions such as no operation can be realized. This can realize transmission protection and avoid data misreading. In addition, when there is movement at the load end, the real-time first torque can be converted into real-time load change, corresponding to the real-time required drive power output, thereby realizing good closed-loop control and achieving the goal of energy saving.

[0135] See Figure 1 An embodiment of this application provides a conveying system including a power unit 11 and a conveying unit 12; the power unit 11 is connected to the conveying unit 12.

[0136] In some examples, the power unit 11 can be a unit that provides power to the entire conveying system, specifically an electric motor, diesel engine, gasoline engine, engine, motor, etc. It is understood that the power unit 11 in this embodiment is not limited to one of the above types, and the power unit 11 can be any device or component that can provide power.

[0137] The conveying unit 12 moves, thereby driving the transport load, which can be ore, sand, cement, coal, etc.

[0138] The conveying unit 12 can specifically be a conveyor belt, conveyor box, or other component with conveying capabilities.

[0139] In this embodiment, the load transported by the conveying unit 12 is detected in terms of the load's weight or volume.

[0140] A first torque detection module 21 is provided on the drive shaft between the power unit 11 and the conveying unit 12; the first torque detection module 21 is communicatively connected to the data processing module 22.

[0141] The first torque detection module 21 and the data processing module 22 can be connected by a wire to achieve communication, or they can be connected wirelessly to achieve communication.

[0142] The first torque detection module 21 in this embodiment is used to detect the first torque output by the output shaft of the power unit 11; the first torque can drive the transmission unit 12 so that the transmission unit 12 drives the conveying unit 12 to move.

[0143] When the first torque detection module 21 is located on the output shaft of the power unit 11, the first torque detection module 21 can detect the first torque output by the transmission shaft, which can drive the conveying unit 12 to move.

[0144] The first torque detection module 21 can be made of strain material, specifically a ring structure. The ring structure is set on the output shaft of the power unit 11. It can be understood that the transmission shaft between the power unit 11 and the conveying unit 12 can be the output shaft of the power unit 11.

[0145] In some examples, the first torque detection module 21 is specifically used to detect the deformation of the output shaft of the power unit 11 when the first torque detection module 21 is located on the output shaft of the power unit 11; determine the voltage or current corresponding to the deformation based on the deformation and a preset bridge; determine the first torque output by the output shaft of the power unit 11 based on the voltage and a preset voltage-torque correspondence; or, determine the first torque output by the output shaft of the power unit 11 based on the current and a preset current-torque correspondence.

[0146] The data processing module 22 in this embodiment is used to receive the first torque detected by the first torque detection module 21, and determine the transport capacity of the conveying unit 12 based on the first torque.

[0147] The method for determining the transport volume is the same as that in the aforementioned related embodiments, and will not be repeated here.

[0148] It is understood that the capacity in this embodiment can be the capacity at a single moment.

[0149] In this embodiment, the first torque detection module 21 is communicatively connected to the data processing module 22. The first torque detection module 21 detects the first torque output by the transmission shaft between the power unit 11 and the conveying unit 12. The first torque can drive the conveying unit 12 to move. The data processing module 22 receives the first torque detected by the first torque detection module 21 and determines the conveying capacity of the conveying unit 12 based on the first torque. Since the first torque detection module 21 detects the first torque and determines the conveying capacity of the conveying unit 12 based on the first torque, it is easier to reduce the error of the conveying capacity detection and improve the accuracy of the conveying capacity detection. In addition, this embodiment provides a new conveying capacity detection method, thereby enriching the conveying capacity detection methods.

[0150] Another embodiment of this application is basically the same as the above embodiment, except that the speed detection module 23 is provided in the transmission shaft and / or conveying unit 12 in this embodiment; the speed detection module 23 is communicatively connected to the data processing module 22.

[0151] The speed detection module 23 is used to detect the rotational speed of the output shaft of the power unit 11 and / or the speed of the conveying unit 12.

[0152] The speed detection module 23 in this embodiment is the same as the speed detection module 23 in the aforementioned related embodiments. For details, please refer to the aforementioned embodiments, and it will not be repeated here.

[0153] The data processing module 22 is used to determine whether the conveying system 13 is in a fault state based on the output of the speed detection module 23 and the first torque.

[0154] In this embodiment, the process of determining whether the conveying system is in a fault state is the same as the process of determining whether the conveying system is in a fault state in the aforementioned related embodiments. For details, please refer to the aforementioned embodiments, and they will not be repeated here.

[0155] In some examples, the conveying system also includes a drive unit; the drive unit is connected to the power unit 11; the data processing module 22 is also used to send a stop command to the drive unit to stop the power unit 11 when the first torque exceeds a preset threshold and at least one of the rotational speed of the drive shaft and the speed of the conveying unit 12 is zero.

[0156] The method of sending a stop command to the drive unit in this embodiment is the same as that in the aforementioned related embodiments. For details, please refer to the aforementioned embodiments, which will not be repeated here.

[0157] Another embodiment of this application is basically the same as the above embodiment, except that the conveying system of this embodiment further includes a transmission unit 13. One end of the transmission unit 13 is connected to the power unit 11 through a first transmission shaft 14, and the other end is connected to the conveying unit 12 through a second transmission shaft 15.

[0158] In this embodiment, the speed detection module is specifically used to detect the rotational speed of the first drive shaft 14, the rotational speed of the second drive shaft 15, and / or the speed of the conveying unit.

[0159] In this embodiment, the data processing module is specifically used to send a stop command to the drive unit when the first torque exceeds a preset threshold and at least one of the rotational speed of the first drive shaft 14, the rotational speed of the second drive shaft 15, and the speed of the conveying unit is zero, so as to stop the power unit 11 from working.

[0160] As an alternative, another embodiment of this application is basically the same as the above embodiment, except that the conveying system in this embodiment further includes a transmission unit 13. One end of the transmission unit 13 is connected to the power unit 11 via a first transmission shaft 14, and the other end is connected to the conveying unit 12 via a second transmission shaft 15. A first torque detection module 21 is disposed on the first transmission shaft 14 or the second transmission shaft 15.

The detection module 21 is mounted on the first drive shaft 14, and the second torque detection module 24 is mounted on the second drive shaft 15, and the second torque detection module 24 is communicatively connected to the data processing module 22; the first torque detection module 21 is used to detect the first torque output by the first drive shaft 14; the second torque detection module 24 is used to detect the second torque output by the second drive shaft 15; the data processing module 22 is specifically used to receive the first torque detected by the first torque detection module 21 and / or the second torque detected by the second torque detection module 24, and determine the conveying capacity of the conveying unit based on the first torque and / or the second torque.
