[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The present application provides a belt conveyor fault detection method, which is applied to Fig. 9 The belt conveyor control system shown in Fig. 9 As shown, the belt conveyor control system may include a fault occurrence module 100 and an equipment fault processing storage module 110, wherein the fault occurrence module 100 may include a digital fault occurrence module 120, an equipment direct fault occurrence module 130, an equipment indirect fault occurrence module 140 and a protection device fault occurrence module 150, and the equipment fault processing storage module 110 is respectively connected to the digital fault occurrence module 120, the equipment direct fault occurrence module 130, the equipment indirect fault occurrence module 140 and the protection device fault occurrence module 150 in communication;

[0051] like Figure 1 As shown, an embodiment of the present application provides a belt conveyor fault detection method, which may include:

[0052] S10 , the digital fault generating module 120 monitors the fault parameters of the motor of the belt conveyor and outputs the fault parameters of the motor to the equipment fault processing and storing module 110 .

[0053] Among them, the digital fault occurrence module 120 can be used to monitor the temperature and current of the motor. The module can be a hardware composed of a controller, multiple sensors and multiple connecting wires to detect the temperature and current of the motor. The sensor is connected to the controller and the motor respectively through the connecting wire. The sensor can include a temperature sensor and a current sensor. The data of the relevant parameters of the motor are obtained through multiple sensors, and the data of the relevant parameters are sent to the controller. The controller determines whether the temperature and current of the motor are faulty according to the data. The digital fault occurrence module 120 may include a data input port, a fault occurrence port and a fault input port. The data input port is connected to the fault occurrence port and the fault output port respectively. The data input port may include a basic input, an alarm input and a normal shutdown input. The basic input is the motor temperature and motor current feedback data. The alarm input is the upper and lower limit range of the alarm corresponding to each motor temperature and motor current. The normal shutdown input is the upper and lower limit range of the normal shutdown fault corresponding to each motor temperature and motor current. The fault occurrence port calculates the motor temperature and motor current feedback data in the basic input according to the upper and lower limit ranges contained in the alarm input and the normal shutdown input. If the motor temperature and motor current feedback data exceed the upper and lower limit ranges, it means that the motor has failed. The fault output port sends fault parameters to the equipment fault processing storage module 110. The fault parameters include fault instructions, occurring equipment, fault level and fault source. The occurring equipment is a motor. The fault level is a comprehensive alarm fault or a normal shutdown comprehensive fault. The fault source is temperature or current.

[0054] The motor provides power for the belt conveyor to transport objects. If the operating index of the belt conveyor is abnormal, such as the load of the belt conveyor is too large, it is very easy to cause the temperature of the motor to rise and the current to be abnormal, thus causing the motor to fail. If the motor fails, the belt conveyor will stop running, so a dedicated module is needed to detect the status of the motor so that the fault can be quickly located when the motor fails.

[0055] S11 . The equipment direct fault generating module 130 monitors the fault parameters of the auxiliary equipment of the belt conveyor and outputs the fault parameters of the auxiliary equipment to the equipment fault processing and storing module 110 .

[0056] Among them, the device direct fault occurrence module 130 can be used to monitor the status of the belt conveyor auxiliary equipment. The auxiliary equipment can include the motor, brake, motor fan and other auxiliary equipment of the belt conveyor. The device direct fault occurrence module 130 can monitor the auxiliary equipment by hardware consisting of a controller, multiple sensors and multiple connecting lines. The device direct fault occurrence module 130 may include an equipment access port, a fault occurrence port and a fault output port. The equipment access port is connected to each auxiliary equipment, and the relevant data of the auxiliary equipment can be transmitted through the equipment access port. The equipment access port may include an emergency stop equipment access port, a normal stop equipment access port, an alarm equipment access port and an equipment name port. The fault occurrence port can monitor the equipment access port in real time. If a fault signal is detected, it is connected to the fault output port. The fault output port sends fault parameters to the equipment fault processing storage module 110. The fault parameters include fault instructions, occurrence equipment, fault level and fault source. The fault equipment and fault level come from the equipment access port. The fault source is the equipment itself, which means that one or more of the auxiliary equipment has failed.

[0057] The auxiliary equipment plays an important role in the entire belt conveyor. For example, the motor provides power for the belt conveyor, and the motor fan dissipates heat for the belt conveyor. Therefore, a dedicated module is needed to monitor the status of the auxiliary equipment to facilitate the rapid location of faults in the auxiliary equipment and prevent the failure of the auxiliary equipment from affecting the belt conveyor.

[0058] S12 , the equipment indirect fault generating module 140 monitors the fault parameters of the operation fault of the belt conveyor and outputs the fault parameters of the operation fault to the equipment fault processing storage module 110 .

[0059] Among them, the equipment indirect fault generation module 140 can be used to monitor the operational faults of the belt conveyor equipment, that is, when the belt conveyor is started and stopped, the equipment in the belt conveyor responds to the operation to start or stop, and whether a fault occurs is determined by the operation of the equipment in the belt conveyor. If the equipment does not start or stop accordingly when the belt conveyor is started and stopped, it means that the equipment has failed. The equipment indirect fault generation module 140 can be composed of hardware consisting of a controller, multiple sensors and multiple connecting lines to detect the operations performed on the belt conveyor. The equipment indirect fault generation module 140 can include an equipment input port, a fault generation port and a fault output port. The device input port is connected to the start / stop signal of the device and the feedback operation signal of the device. The fault occurrence port can be a port for jointly monitoring the start / stop signal of the device connected to the device input port and the feedback operation signal of the device, and performing timing calculation. When the start / stop signal changes, if the device input port has not received the start / stop feedback change of the device after a specified time, a start timeout alarm fault and a stop timeout alarm fault will occur, and the fault will be connected to the fault output port. The fault output port sends fault parameters to the device fault processing storage module 110. The fault parameters include fault instructions, occurrence device, fault level and fault source. The occurrence device source is the device input port, which means that the fault is the device connected to the device input port, the fault level is alarm, and the fault source is device operation timeout.

[0060] The equipment in the belt conveyor is monitored for faults through a dedicated module. When the belt conveyor is operated, if a fault occurs, the equipment indirect fault occurrence module 140 can be used to quickly locate which one or more devices have failed.

[0061] S13 , the protection device fault generating module 150 monitors the fault parameters of the protection switch device of the belt conveyor and outputs the fault parameters of the protection switch device to the equipment fault processing storage module 110 .

[0062] Among them, the protection device failure module 150 is used to monitor the protection switch device of the belt conveyor. The protection switch device may include a pull rope switch. The pull rope switch is a protection device used for emergency accident parking of the conveyor. When an emergency occurs, the rope can be pulled anywhere on the scene to send an alarm signal, and then the machine will be self-locked and shut down. The protection switch device may also include a conveyor belt anti-deviation device, a conveyor belt longitudinal tear protection device, a conveyor belt slip detection device, and a pull wire protection device. The protection device failure module 150 can be composed of a controller, a plurality of sensors, and a plurality of connecting wires to detect the state of the protection switch device of the belt conveyor. The protection device failure module 150 may include a device input port, a fault occurrence port, and a fault input port. The device input port is divided into three parts: the head, the middle, and the tail, so as to more accurately locate the part of the belt conveyor where the failure of the protection switch device specifically occurs. The fault level of the fault occurrence port can be divided into comprehensive alarm fault, normal shutdown comprehensive fault and emergency shutdown comprehensive fault. The fault occurrence port can monitor the equipment access port in real time. Once a fault signal is received, it is connected to the fault output port. The fault output port sends fault parameters to the equipment fault processing storage module 110. The fault parameters include fault instructions, occurring equipment, fault level and fault source. The name of the occurring equipment is the segment plus the name, such as head deviation, which means that the conveyor belt at the head of the belt conveyor deviates. The fault level is the three levels of the fault input port, and the fault source is the protective switch device.

[0063] The protection switch device is used to protect the belt conveyor in operation. If the protection switch fails, it will cause safety hazards to the belt conveyor, which is likely to cause damage to the belt conveyor during operation. Therefore, a dedicated module is required to perform real-time fault monitoring of the status of the protection switch device, so that when the protection device switch fails, the fault can be quickly located to prevent the belt conveyor from failing and affecting the operator.

[0064] S14. After receiving the fault parameters, the equipment fault processing storage module 110 generates a new belt conveyor fault, sets the fault state of the new belt conveyor fault as the current fault, and fills the received fault parameters into the fault attributes of the new belt conveyor fault.

[0065] The equipment fault processing storage module 110 obtains fault parameters from the fault generation module 100 and fills the data of the fault parameters into the corresponding attributes of a newly generated belt conveyor fault, so as to facilitate the subsequent rapid positioning of the belt conveyor fault.

[0066] Furthermore, there is no order of precedence for steps S10-S13, but there is an order of precedence for steps S10-S13 and step S14. Each module can be hardware or software. Multiple hardware can be connected separately to achieve the effect of quickly locating the fault of the belt conveyor, or they can be integrated into a chip to achieve the effect of quickly locating the fault of the belt conveyor through the chip.

[0067] This embodiment provides a belt conveyor fault detection method, which includes monitoring different faults in the belt conveyor through different modules included in the belt conveyor system, and sending fault parameters to the equipment fault processing storage module 110. The equipment fault processing storage module 110 generates a new belt conveyor fault based on the fault parameters sent by different modules, and fills the received fault parameters into the fault attribute of the new belt conveyor fault. By performing corresponding fault monitoring on various aspects of the belt conveyor through different modules, when a fault occurs, it is not necessary to invest a lot of manpower and material resources to locate the fault in the belt conveyor, and the belt conveyor fault can be quickly located directly through the belt conveyor fault with the fault parameters filled in.

[0068] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.10 As shown, the belt conveyor control system may further include a working condition monitoring module 160 which is in communication with the equipment fault processing storage module 110, such as Figure 2 As shown, Figure 1 The illustrated embodiment may also include:

[0069] S15, the working condition monitoring module 160 obtains the working condition auxiliary data before the new belt conveyor fault is generated and sends the working condition auxiliary data to the equipment fault processing storage module 110;

[0070] S16. The equipment fault processing storage module 110 stores the auxiliary working condition data as new working condition data of the belt conveyor fault.

[0071] Optionally, the order of any step in steps S10-S14 and step S15 can be any order, which is not limited in this application.

[0072] The working condition monitoring module 160 can be used to provide the working condition auxiliary data of the belt conveyor to the equipment fault processing storage module 110, so that the equipment fault processing storage module 110 can store the working condition auxiliary data as the newly generated working condition data of the belt conveyor fault. The working condition auxiliary data of the belt conveyor can include at least one of the operation signal, climate, belt tension, belt speed and load of the belt conveyor.

[0073] Furthermore, the equipment fault processing storage module 110 can use its own working condition-fault correspondence table to determine the fault of the belt conveyor. The working condition monitoring module 160 provides the working condition data of the belt conveyor after the fault occurs to the equipment fault processing storage module 110, and the equipment fault processing storage module 110 determines the most likely fault of the belt conveyor under this working condition according to the correspondence table; the intelligent machine with the equipment fault processing storage module 110 can also be learned multiple times. After the working condition monitoring module 160 provides the working condition data to the intelligent machine, the intelligent machine can automatically output the most likely fault corresponding to the working condition data. The equipment fault processing storage module 110 can quickly locate the fault of the belt conveyor based on the fault parameters sent by the fault occurrence module 100 and the working condition auxiliary data sent by the working condition monitoring module 160.

[0074] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.10 As shown, the belt conveyor control system may further include a human-machine interface module 170 and a display screen 180, wherein the human-machine interface module 170 is communicatively connected to the equipment fault processing storage module 110, and the display screen 180 is communicatively connected to the human-machine interface module 170, as shown in FIG. Figure 3 As shown, Figure 2 The illustrated embodiment may also include:

[0075] S17, the human-machine interface module 170 obtains the new belt conveyor fault generated by the equipment fault processing storage module 110, and outputs the new belt conveyor fault to the display screen 180 for display.

[0076] Among them, the human-machine interface module 170 is used to display the faults of the belt conveyor and the auxiliary analysis function block. The human-machine interface module 170 can display the newly generated belt conveyor faults sent by the equipment fault processing storage module 110, so that the operator can make a solution to the fault according to the displayed belt conveyor fault; the auxiliary analysis function block can display the various data of each module in the current fault occurrence module 100, so that the operator can quickly locate the historical faults through the various data of each module, and immediately make a solution to the fault based on the historical fault.

[0077] By displaying the newly generated belt conveyor fault sent by the device fault processing storage module 110, the belt conveyor fault can be quickly located without spending additional manpower and material resources to troubleshoot the fault.

[0078] like Figure 4 As shown, in another belt conveyor fault detection method provided in an embodiment of the present application, Figure 3 The illustrated embodiment may also include:

[0079] S18. The human-machine interface module 170 determines the fault level based on the operating condition data of the new belt conveyor fault and the fault parameters received by the equipment fault processing storage module 110. The fault levels include: comprehensive alarm fault, normal shutdown comprehensive fault and emergency shutdown comprehensive fault.

[0080] Among them, because the fault parameters received by the equipment fault processing storage module 110 have their own fault levels, the human-machine interface module 170 can further determine the fault level of the belt conveyor based on the working condition data.

[0081] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.10 The display screen 180 shown can display the home page and the pages, and the pages are divided based on the equipment included in the belt conveyor, such as Figure 5 As shown, Figure 4 The illustrated embodiment may also include:

[0082] S19, the human-machine interface module 170 outputs the fault level and the fault parameters received by the equipment fault processing storage module 110 to the home page of the display screen 180 for display.

[0083] S20 , the human-machine interface module 170 obtains the equipment fault of the equipment included in the belt conveyor from the fault parameters received by the equipment fault processing storage module 110 , and outputs the equipment fault to the page corresponding to the equipment to which the equipment fault belongs.

[0084] Among them, the display mode of the display screen 180 is divided into a home page and paging, which can display the importance of the data. The home page can display important data such as fault level and fault category. The fault category is obtained based on the newly generated belt conveyor fault analysis sent by the equipment fault processing storage module 110. The fault category can be divided into temperature fault, current fault, equipment fault, operation fault and protection device fault. The paging is divided according to the equipment, and the fault status of each equipment is output to the corresponding paging, so as to more clearly display which equipment has failed. The paging can also display the summary data after classification statistics such as the equipment with the most faults and which section has the most deviations. By dividing the display mode of the display screen 180, it is convenient for operators to quickly locate specific faults based on the displayed data.

[0085] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.10 The belt conveyor control system shown may further include an equipment ready generation module 190 which is communicatively connected to the equipment fault processing storage module 110, such as Figure 6 As shown, Figure 3 The illustrated embodiment may also include:

[0086] S21, the equipment ready module 190 determines whether there is a belt conveyor fault whose fault state is the current fault. If not, step S22 is executed; if so, step S23 is executed;

[0087] S22. Generate a current system ready signal.

[0088] S23: Do not generate the current system ready signal and maintain the current state.

[0089] Optionally, step S21 only needs to be executed after step S14, so the order of any step in steps S15-S17 and step S21 can be any order, and this application does not limit it.

[0090] Among them, the equipment readiness generation module 190 is connected to the equipment fault processing storage module 110 to facilitate the determination of whether the equipment fault processing storage module 110 generates a new belt conveyor fault. If not, a system readiness signal can be generated to indicate that the current belt conveyor is in a state where it can operate normally.

[0091] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.10 The equipment ready module 190 is in communication with the human-machine interface module 170, as shown in FIG. Figure 7 As shown, Figure 6 The illustrated embodiment may also include:

[0092] S24, the human-machine interface module 170 obtains the current system ready signal sent by the equipment ready generation module 190 and outputs it to the display screen 180 for display.

[0093] Among them, the equipment readiness generating module 190 is connected with the human-machine interface module 170, so that the equipment readiness generating module 190 sends a system readiness signal to the human-machine interface module 170, and the human-machine interface module 170 outputs it to the home page of the display screen 180 for display, so that the operator can determine that the current belt conveyor can operate normally through the system readiness signal displayed on the home page of the display screen 180.

[0094] According to another belt conveyor fault detection method provided by an embodiment of the present application, Fig.11 The belt conveyor control system shown in the figure may also include a switching control module 200 which is in communication with the fault generation module 100. Figure 8 As shown, Figure 1 The illustrated embodiment may also include:

[0095] S25. The switching control module 200 sends a fault response control signal to the fault occurrence module 100 to control the response action of the fault occurrence module 100 after detecting the fault parameter.

[0096] Among them, the switching control module 200 is respectively connected to the digital fault occurrence module 120, the equipment direct fault occurrence module 130, the equipment indirect fault occurrence module 140 and the protection device fault occurrence module 150 in the fault occurrence module 100, and can downgrade the shutdown fault in the fault occurrence module 100, and manually downgrade the shutdown comprehensive fault to an alarm comprehensive fault. In the belt conveyor, the fault levels include: comprehensive alarm fault, normal shutdown comprehensive fault and emergency shutdown comprehensive fault. The highest level is the emergency shutdown comprehensive fault, the lowest level is the comprehensive alarm fault, and the normal shutdown comprehensive fault is in the middle. When the operator determines that the fault occurring at this time can be downgraded from the shutdown comprehensive fault to the alarm comprehensive fault based on the data displayed on the display screen 180, it can be downgraded through the switching control module 200. The switching control module 200 only provides an optional function. By default, the fault will not be downgraded.

[0097] like Fig. 9 As shown, the embodiment of the present application further provides a belt conveyor control system, which may include a fault occurrence module 100 and an equipment fault processing storage module 110, wherein the fault occurrence module 100 may include a digital fault occurrence module 120, an equipment direct fault occurrence module 130, an equipment indirect fault occurrence module 140 and a protection device fault occurrence module 150, and the equipment fault processing storage module 110 is respectively connected to the digital fault occurrence module 120, the equipment direct fault occurrence module 130, the equipment indirect fault occurrence module 140 and the protection device fault occurrence module 150 in communication;

[0098] The digital fault generation module 120 monitors the fault parameters of the motor of the belt conveyor and outputs the fault parameters of the motor to the equipment fault processing storage module 110;

[0099] The equipment direct fault occurrence module 130 monitors the fault parameters of the auxiliary equipment of the belt conveyor and outputs the fault parameters of the auxiliary equipment to the equipment fault processing storage module 110;

[0100] The equipment indirect fault generation module 140 monitors the fault parameters of the operation fault of the belt conveyor and outputs the fault parameters of the operation fault to the equipment fault processing storage module 110;
