[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] To better understand the technical solutions of the present application, the following will be described in detail in combination with the accompanying drawings of the description and the specific embodiments.

[0047] In the field of industrial flue gas treatment, the dense-phase pneumatic conveying system is widely used in the efficient transportation of dust materials. With the increase in the dust treatment volume, the dense-phase pneumatic conveying system with multiple silo pumps in parallel has gradually become the mainstream configuration.

[0048] When multiple bin pumps operate in parallel, the traditional pneumatic conveying control method cannot flexibly adjust the operation strategy of the bin pumps according to the real-time working conditions, resulting in limited overall system efficiency. Moreover, when local failures occur, it is extremely easy to cause the paralysis of the global system, seriously affecting the continuity and stability of dust conveying. At present, to address such problems, the system highly relies on manual intervention, which not only increases labor costs but also may further exacerbate the instability factors of the system due to the timeliness and accuracy of manual operations.

[0049] In summary, how to improve the automation degree of bin pump operation to increase the dust conveying efficiency while reducing the system failure rate has become an urgent technical problem in this field.

[0050] The main solution of the embodiment of the present application is: determining the bin pump conveying mode according to the material quantity of the material to be conveyed, and the bin pump conveying mode is parallel conveying or sequential conveying; controlling each conveying bin pump to execute a preset material conveying task according to the bin pump conveying mode; during the execution of the material conveying task, real-time monitoring the operation status of each conveying bin pump, and adjusting the material conveying task according to the operation status.

[0051] Thus, in this embodiment, by determining the bin pump conveying mode of each conveying bin pump according to the material quantity of the material to be conveyed, and real-time monitoring the operation status of each conveying bin pump during the execution of the material conveying task to dynamically adjust the conveying task, the automation degree of bin pump operation is improved. While improving the overall conveying efficiency of the system, the ability of the system to cope with working condition changes is effectively enhanced, preventing local failures from causing global paralysis, and ensuring the continuity and stability of dust conveying.

[0052] It should be noted that the execution subject of this embodiment can be a computer service device with data processing, network communication, and program running functions, such as a server, a host computer, a tablet computer, a personal computer, etc., or an electronic device capable of implementing the above functions.

[0053] Based on this, the embodiment of the present application provides a method for controlling the operation of a bin pump, referring to Figure 1 , Figure 1 which is a schematic flow chart of the first embodiment of the method for controlling the operation of the bin pump of the present application.

[0054] In this embodiment, the method for controlling the operation of the bin pump is applied to a pneumatic conveying system. The pneumatic conveying system includes each parallel conveying bin pump. The method for controlling the operation of the bin pump includes steps S10 to S30:

[0055] Step S10, determining the bin pump conveying mode according to the material quantity of the material to be conveyed, and the bin pump conveying mode is parallel conveying or sequential conveying;

[0056] It should be noted that in this embodiment, the pneumatic conveying system is a system that uses high-pressure gas as a power source to convey materials (such as dust) from one place to another. The pneumatic conveying system includes a software part and a hardware part. The software part can be loaded into an electronic device, and in the hardware part, the conveying silo pump is a device for temporarily storing and conveying materials.

[0057] Determine whether to adopt a parallel conveying mode or a sequential conveying mode according to the material quantity (such as dust quantity) of the material to be conveyed. For example, when the material quantity exceeds a preset threshold, select the parallel conveying mode to improve the conveying efficiency; when the material quantity does not exceed the preset threshold, select the sequential conveying mode to reduce the burden of pipeline conveying. The size of the preset threshold can be set based on the actual scenario, and no specific limitation is made in this embodiment.

[0058] It is worth mentioning that currently in the flue gas treatment scenario, after the dust in the flue gas is collected by a dust collector, it is then transported out through a pneumatic conveying system. After the dust collector collects the dust in the flue gas, it will be stored in the ash hopper at the bottom of the dust collector. In a feasible implementation manner, a flow meter and a dust concentration monitor can be installed at the inlet of the dust collector to monitor the flue gas flow rate and dust concentration entering the dust collector in real time, thereby determining the dust quantity of the dust to be conveyed; in another feasible implementation manner, a level gauge, such as a radio frequency admittance level gauge, a rotary paddle level gauge, or an ultrasonic level gauge, can be installed inside the ash hopper, and the level height of the dust in the ash hopper can be indirectly judged by measuring the interaction between the dust and the probe of the level gauge, thereby determining the dust quantity of the dust to be conveyed.

[0059] Step S20, control each conveying silo pump to execute a preset material conveying task according to the silo pump conveying mode;

[0060] According to the determined conveying mode, control each conveying silo pump to operate according to a preset material conveying task. Specifically, in the parallel conveying mode, each conveying silo pump is started simultaneously and the material conveying task is carried out simultaneously; in the sequential conveying mode, each conveying silo pump is started sequentially according to a predetermined order and each completes its own material conveying task in turn.

[0061] In a feasible embodiment, step S20 may include steps S201 to S202:

[0062] Step S201, when the silo pump conveying mode is parallel conveying, control each conveying silo pump to execute a preset material conveying task simultaneously;

[0063] When the silo pump conveying mode is determined to be parallel conveying, start all the parallel conveying silo pumps participating in the conveying simultaneously, and control them to execute the preset material conveying task simultaneously. In this mode, each conveying silo pump will independently perform operations such as feeding and discharging for the material conveying task to maximize the conveying efficiency.

[0064] It is worth mentioning that since the feed inlets of the respective conveying bin pumps are connected to different material storage spaces (such as different hoppers), the material quantities of the materials to be conveyed by the respective conveying bin pumps may be different. Therefore, during the process of synchronously executing the material conveying tasks by the respective conveying bin pumps, the feeding duration and discharging duration of each conveying bin pump may also be different. In this embodiment, the feeding duration and discharging duration of each conveying bin pump are not specifically limited.

[0065] Exemplarily, high, medium, and low level gauges are added to the hoppers on the bin pumps to determine the amount of material inside the hoppers; according to the amount of material in the hoppers, the feeding duration and discharging duration are automatically determined. For example: the feeding duration and discharging duration for high level are set for a longer time, the medium level is the next, and the low level is the shortest or not executed.

[0066] Step S202, when the bin pump conveying mode is sequential conveying, control each conveying bin pump to sequentially execute the material conveying task according to the preset priority rule and the preset cyclic waiting time.

[0067] When the bin pump conveying mode is determined to be sequential conveying, according to the preset priority rule and cyclic waiting time, control each conveying bin pump to execute the material conveying task in sequence. Specifically, the system will first determine the conveying order of each conveying bin pump. The conveying order can be set based on factors such as the number of the conveying bin pump, historical operation efficiency, or the time of being put into use, etc. Then, in accordance with this conveying order, start each conveying bin pump in sequence and control it to complete operations such as feeding and discharging for the material conveying task. After each conveying bin pump completes a material conveying task, the system will wait for the preset cyclic waiting time, and then start the next conveying bin pump to execute the material conveying task. The cyclic waiting time set for each conveying bin pump can be different.

[0068] Exemplarily, high, medium, and low level gauges are added to the hoppers above the bin pumps, and the priority of bin pump conveying is determined according to the status of the level gauges to achieve intelligent jump of the conveying order. For example, when a certain hopper is at low level, it is automatically cut off; when it reaches medium level, the bin pump is put into the conveying state; when it reaches high level, the priority is the highest, and immediately execute after the current conveying is completed.

[0069] In addition, in a feasible implementation manner, the pneumatic conveying system further includes a material conveying pipeline, which is connected to the discharge outlets of the respective conveying bin pumps. The system can adjust the discharging timing sequence of each conveying bin pump in real time based on the pressure feedback of the material conveying pipeline to avoid the superposition of discharging pressures of multiple bin pumps.

[0070] Exemplarily, when discharging materials, first pressurize the inside of the silo pump, and then open the discharge valve to convey the pressure into the pipeline; at this time, the pipeline pressure will first increase and then decrease (a high pipeline pressure indicates that there is material inside the pipeline, and a low pipeline pressure indicates that the pipeline is unobstructed). In the subroutine C1_STEP = 6 (indicating opening the discharge valve), after the discharge valve has been opened for 5 seconds, judge the high or low of the pipeline pressure. If the pressure reaches a low value, it means that the discharging is completed and the next step will be executed. If the pressure never reaches a low value, it means that the pipeline is blocked and the machine will stop and give an alarm.

[0071] Thus, the system can implement precise control over each conveying silo pump according to different conveying modes, thereby ensuring the efficient and stable completion of the material conveying task.

[0072] Step S30, during the execution of the material conveying task, real-time monitor the operating status of each conveying silo pump and adjust the material conveying task according to the operating status.

[0073] During the execution of the material conveying task, the system real-time monitors the operating status of each conveying silo pump and adjusts its material conveying task according to the operating status. For example, if it is detected that a certain conveying silo pump fails or is not put into the automatic state, the system will automatically skip this conveying silo pump to avoid affecting the entire conveying system.

[0074] In this way, in the embodiment of the present application, by determining the silo pump conveying mode of each conveying silo pump according to the material quantity to be conveyed and real-time monitoring the operating status of each conveying silo pump during the execution of the material conveying task to dynamically adjust the conveying task, the automation degree of the silo pump operation is improved. While improving the overall conveying efficiency of the system, the ability of the system to cope with working condition changes is effectively enhanced, preventing local failures from causing global paralysis, and ensuring the continuity and stability of dust conveying.

[0075] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as that in the above-mentioned embodiment one can be referred to the above introduction and will not be repeated hereinafter. On this basis, as Figure 2 shown, step S30 may include steps S301 to S304:

[0076] Step S301, during the execution of the material conveying task, real-time monitor the operating status of each conveying silo pump;

[0077] During the process of the system executing the material conveying task, it will continuously and real-time monitor the operating status of each conveying silo pump to timely discover any abnormal situations that may affect the conveying efficiency or system safety.

[0078] In a feasible embodiment, step S301 may include steps S3011 to S3012:

[0079] Step S3011, during the execution of the material conveying task, read the step sequence status bits of each conveying silo pump in real time;

[0080] The system obtains the current operation stage or status of each conveying silo pump by reading the step sequence status bits of each conveying silo pump in real time. Among them, the step sequence status bit is a parameter in the silo pump control program, which reflects the execution of each step of the conveying silo pump from feeding preparation to discharging completion.

[0081] Step S3012, determine the operation status of each conveying silo pump according to the correspondence between the step sequence status bit and the operation status.

[0082] According to the predefined correspondence between the step sequence status bit and the operation status, analyze the read step sequence status bit to determine the current specific operation status of each conveying silo pump. These operation statuses can include states such as first start, waiting to stop, and fault.

[0083] Step S302, for each conveying silo pump, when the operation status of the conveying silo pump is the first start, control the conveying silo pump to perform an emptying operation before executing the material conveying task;

[0084] When the system monitors that the operation status of a certain conveying silo pump is the first start, it will control the conveying silo pump to perform an emptying operation before executing the material conveying task to ensure that there is no residual material inside the conveying silo pump and in the conveying pipeline, thus avoiding blockage or conflict during the conveying process.

[0085] Step S303, for each conveying silo pump, when the operation status of the conveying silo pump is the waiting-to-stop state, control the conveying silo pump to perform an emptying operation after executing the material conveying task;

[0086] When the system monitors that the operation status of a certain conveying silo pump is the waiting-to-stop state, or when a certain conveying silo pump receives a stop instruction, it will control the conveying silo pump to perform an emptying operation after completing the current material conveying task to ensure that the conveying silo pump can completely empty the internal material before stopping, and avoid the accumulation of material in the silo pump or blockage of the pipeline.

[0087] Step S304, for each conveying silo pump, when the operation status of the conveying silo pump is the fault state, control the conveying silo pump to stop executing the material conveying task.

[0088] When the system monitors that the operation status of a certain conveying silo pump is the fault state, it will immediately control the conveying silo pump to stop executing the material conveying task to prevent the further expansion of the fault and affect the stable operation of the entire conveying system. At the same time, the system will also record the current fault information for subsequent fault troubleshooting and repair.

[0089] Thus, the system can comprehensively monitor and dynamically adjust each delivery silo pump during the execution of the material conveying task, ensuring the stable operation and efficient conveying of the system.

[0090] In a feasible embodiment, the material conveying task includes a feeding stage, and step S20 may further include steps A10 to A20:

[0091] Step A10, for each delivery silo pump, during the feeding stage, open the feed valve and balance valve of the delivery silo pump, and complete the material filling according to the preset feeding duration;

[0092] For each delivery silo pump, when entering the feeding stage, the system will control to open the feed valve and balance valve of the delivery silo pump. Among them, the opening of the feed valve allows materials (such as dust) to enter the interior of the delivery silo pump, while the opening of the balance valve helps to maintain the stability of the pressure inside the delivery silo pump, preventing unsmooth material conveyance caused by pressure changes.

[0093] The system will accurately control the filling amount of materials according to the preset feeding duration, ensuring that each delivery silo pump can obtain an appropriate amount of materials for subsequent conveyance.

[0094] Step A20, after the feeding is completed, close the feed valve and balance valve.

[0095] When the feeding stage is completed, the system will automatically close the feed valve and balance valve of each delivery silo pump to prevent materials from continuing to enter the delivery silo pump during subsequent conveyance, and at the same time maintain the closed state inside the delivery silo pump to prepare for the discharging stage.

[0096] In a feasible embodiment, the material conveying task includes a discharging stage, and step S20 may further include steps A30 to A50:

[0097] Step A30, for each delivery silo pump, during the discharging stage, open the air inlet valve of the delivery silo pump to inject compressed air into the delivery silo pump;

[0098] For each delivery silo pump, when entering the discharging stage, the system will control to open the air inlet valve of the delivery silo pump. The opening of the air inlet valve allows high-pressure gas (such as compressed air) to enter the interior of the delivery silo pump, providing power for the discharge of materials. By injecting compressed air, the pressure inside the delivery silo pump will gradually increase, creating conditions for subsequent discharging operations.

[0099] Step A40, when the pressure inside the delivery silo pump reaches the preset pressure threshold, open the discharge valve of the delivery silo pump to perform the discharging operation;

[0100] The system will continuously monitor the pressure changes inside each conveying silo pump. When the pressure inside the conveying silo pump reaches the preset pressure threshold, the system will control the opening of the discharge valve of the conveying silo pump. The opening of the discharge valve will allow the material inside the conveying silo pump to be discharged under the action of compressed air and enter the subsequent conveying pipeline for transmission.

[0101] Step A50, close the intake valve and the discharge valve after discharging is completed.

[0102] When the discharging stage is completed, the system will automatically close the intake valve and the discharge valve of each conveying silo pump to stop the injection of compressed air and the discharge of materials, and at the same time maintain the closed state inside the conveying silo pump to prepare for the next material conveying task. By closing the intake valve and the discharge valve, the system can ensure that the silo pump will not be disturbed by the external environment during the idle period and ensure its long-term stable operation.

[0103] Thus, the system can implement precise and efficient control of each conveying silo pump during the feeding stage and the discharging stage of the material conveying task to ensure the smooth completion of the material conveying task.

[0104] Exemplarily, in a feasible implementation scenario, the corresponding relationship between the step sequence status bit (Cn_STEP) and the operating status of each conveying silo pump is predefined as follows:

[0105] 0: Program stop; 1: Feeding preparation; 2: Feeding start; 3: Feeding completed; 4: Discharging preparation; 5: Discharging start, open the intake valve; 6: Open the discharge valve; 7: Close the intake valve and the discharge valve; 8: Discharging completed; 10: Operation failed; where, in the case of multiple conveying silo pumps, n represents the silo pump number. For example, the step sequence status bit of one conveying silo pump is represented as C1_STEP, and the step sequence status bit of another conveying silo pump is represented as C3_STEP.

[0106] On this basis, the flowchart of a certain conveying silo pump performing the material conveying task is as Figure 2As shown, in the bin pump feeding state, i.e., during the feeding stage, the main program issues a feeding instruction. Subsequently, the sequence status bit C1_STEP of the conveying bin pump is set to 1, indicating feeding preparation. Then, the timer is started and the sequence status bit is set to 2, indicating the start of feeding. Next, the inlet valve of the conveying bin pump is opened. After feeding is completed, the sequence status bit is set to 3, indicating that feeding is completed. In the bin pump discharging state, i.e., during the discharging stage, the main program issues a discharging instruction. Subsequently, the sequence status bit C1_STEP of the conveying bin pump is set to 4, indicating discharging preparation. The timer is started again, and the sequence status bit is set to 5, indicating the start of discharging and the opening of the air inlet valve to supplement pressure. After the pressure boosting is completed, the sequence status bit is set to 6, indicating opening the discharge valve. The discharge valve is opened for discharging operation. After discharging is completed, the sequence status bit is set to 8, indicating that discharging is completed. During the execution of this material conveying task, if feeding timeout, pressure boosting timeout, or bin cleaning (discharging) timeout is detected, the sequence status bit is set to 10, indicating that the operation has failed. At this time, it is determined that the conveying bin pump is in a fault state, and the sequence status bit is set to 0, indicating that the program stops. When receiving the instruction of the bin pump cut-off state, the sequence status bit is also set to 0. At this time, all valves of the conveying bin pump are closed, and the timer is reset. Thus, precise control of the material conveying task of the conveying bin pump is completed.

[0107] In a feasible embodiment, the pneumatic conveying system further includes an interaction interface, and the bin pump operation control method may further include step S40:

[0108] Step S40: Receive the input operation parameters through the interaction interface, and display the operation status of each conveying bin pump, the progress of the current material conveying task, and / or the fault alarm information in real time through the interaction interface.

[0109] The pneumatic conveying system is equipped with an interaction interface. Operators can input a series of operation parameters through the interaction interface according to the actual production requirements or system optimization goals. The operation parameters may include but are not limited to: selection of parallel / sequential conveying mode, preset feeding duration, cycle waiting time, preset pressure threshold, conveying speed, priority rules of each bin pump, etc. The system will receive and parse these parameters in real time to ensure that they can be accurately and effectively applied to the subsequent operation control of the bin pump. In this way, operators can flexibly adjust the system configuration to adapt to different pneumatic transmission scenarios.

[0110] The interactive interface can also display the operating status of each conveying silo pump, the progress of the current material conveying task, and / or fault alarm information in real time. Specifically, the operating status of each conveying silo pump includes, but is not limited to, normal operation, first startup, pending shutdown, fault, etc., enabling operators to clearly understand the current situation of each silo pump at a glance; the progress of the current material conveying task can be presented through a progress bar, percentage, or other intuitive forms to show the completion of the material conveying task and help operators grasp the production progress; the fault alarm information can include the fault type, occurrence time, affected conveying silo pump, etc., so that operators can quickly take countermeasures to prevent the fault from expanding or affecting production.

[0111] Thus, through the interactive interface, operators can grasp the operating status of the system in real time, discover and handle potential problems in a timely manner, and ensure the stable and efficient operation of the pneumatic conveying system.

[0112] Exemplarily, in a feasible implementation scenario, the display content of the interactive interface is as Figure 3 shown. This figure shows the interactive interface scenario of the sequential control of the silo pumps in row B. Among them, there are three operation buttons, namely "Start", "Stop", and "Reset", at the top of the interface. Below the buttons, the current status is displayed as "System Shutdown". Further down, there are two silo pump transfer mode options, namely "Same-row Conveying" and "Circular Conveying". The interface also provides options for silo chamber switching and balance valve switching, with three silo chamber options (i.e., the numbers of three conveying silo pumps), namely 2#, 4#, and 6#. Each silo chamber corresponds to a circular selection box. The interface also details various parameters and corresponding values: the feeding time is 30 seconds for all, and the feeding timer is 0 seconds for all; the conveying time is 40 seconds for all, and the conveying timer is 0 seconds for all; the pressurization time is 20 seconds for all, and the pressurization timer is 10 seconds for silo 2# and 0 seconds for silos 4# and 6#; the pressurization completion pressure is displayed as 0.2 MPa; the cleaning pressure is 0.03 MPa; the blockage pressure is 0.3 MPa; the cycle interval is 20 seconds, and the cycle timer is 0 seconds. The overall interface design is simple and clear, and all parameters and operation options are clearly distinguishable, facilitating operators to monitor and control.

[0113] In summary, in this embodiment, the bin pump conveying mode is flexibly determined according to the material quantity of the material to be conveyed. Whether it is parallel conveying or sequential conveying, it can be efficiently adapted, effectively improving the flexibility and adaptability of material conveying. During the execution of the material conveying task, the operating status of each conveying bin pump is monitored in real time, and the material conveying task is adjusted in a timely manner according to the operating status, ensuring the stable operation of the system, reducing the risk of faults. At the same time, the precise control of the feeding stage and the discharging stage, including the accurate operation of the feed valve, balance valve, intake valve and discharge valve, ensures the efficiency and accuracy of material conveying. In addition, the setting of the interaction interface enables the operator to conveniently input operating parameters, and to grasp the operating status, task progress and fault alarm information of each bin pump in real time, facilitating the timely handling of problems and further improving the operability and maintenance efficiency of the system.

[0114] Exemplarily, to help understand the implementation process of the bin pump operation control method obtained by combining this embodiment with the above embodiment, please refer to FIGS. 4(a) and 4(b). The figures provide a brief flow schematic diagram of a bin pump operation control method. Specifically:

[0115] Exemplarily, in a feasible implementation scenario, the corresponding relationship between the main program status bit (AC_STEP) and the operating status is predefined as follows:

[0116] 0: Conveying system shutdown state; 1: System input status bit, enter the judgment of the discharging mode; 2: Start the simultaneous conveying mode; 10: Start the sequential conveying mode; 13: In the sequential conveying mode, the 1# bin executes the feeding step; 16: In the sequential conveying mode, the 1# bin completes discharging; Judge whether to continue according to whether there is a shutdown signal; 17: After the 1# bin finishes conveying in the sequential conveying mode, enter the loop waiting. When the waiting time is up, according to whether AC_X2 (sequential conveying mode, first start status bit) is the first run, select whether to execute the discharging step; 20: In the sequential conveying mode, the 3# bin executes the discharging step; 23: In the sequential conveying mode, the 3# bin executes the feeding step; 25: In the sequential conveying mode, the 3# bin executes the discharging step; 27: After the 3# bin finishes conveying in the sequential conveying mode, enter the loop waiting. When the waiting time is up, according to whether AC_X2 (sequential conveying mode, first start status bit) is the first run, select whether to execute the discharging step; 30: In the sequential conveying mode, the 5# bin executes the discharging step; 33: In the sequential conveying mode, the 5# bin executes the feeding step; 35: In the sequential conveying mode, the 5# bin executes the discharging step; 37: After the 5# bin finishes conveying in the sequential conveying mode, enter the loop waiting. When the waiting time is up, set AC_X2 (sequential conveying mode, first start status bit), and at the same time jump to the feeding step of the 1# bin; 38: The system shutdown preparation (the bin pump is emptied before shutdown) is completed, and enter the equipment shutdown step.

[0117] On this basis, the operation control process of the silo pump includes: when the system main program is in the running state, after receiving the program reset instruction, reset the status bits and fault bits of each silo pump; then set the main program status bit to 0. After receiving the program start instruction, put the program into the automatic state and set the main program status bit to 1, so that each conveying silo pump executes the material conveying task according to the selected silo pump conveying mode.

[0118] When the silo pump conveying mode is simultaneous conveying, as shown in Figure 4(a), first set the main program status bit to 2. If it is detected that the running status of each conveying silo pump is the first start, send a discharging signal to each subprogram, that is, control each conveying silo pump to perform the discharging operation, and receive the discharging completion signal or stop signal of each chamber (i.e., the conveying silo pump). If the stop signal is not received, after the silo pump finishes discharging, execute the loop immediately. After the timing ends, send a feeding instruction to each silo pump, receive the feeding completion signal or stop signal of each silo pump, and finally set the main program status bit to 2 and execute the material conveying task again. In the scenario of non-first start, the feeding operation can be directly performed; if a stop instruction is received during the discharging stage, judge whether the simultaneous conveying shutdown status bit is valid. The simultaneous conveying shutdown status bit is used to judge whether it is the first shutdown. If it is not, the discharging program needs to be restarted to clean the ash before shutdown. If the shutdown status bit is invalid, set the shutdown status bit to 1. If the shutdown status bit is valid, the program operation stops and the main program status bit is set to 0.

[0119] When the bin pump conveying mode is sequential conveying, as shown in Fig. 4(b), taking the numbers of the parallel conveying bin pumps as 1#, 3#, and 5# as an example, the material conveying tasks of each conveying bin pump are controlled in ascending order of the numbers. First, set the main program status position to 10. When it is monitored that bin 1 is running for the first time, send a discharging instruction to bin 1, and then receive the signal indicating that the discharging of bin 1 is completed or stopped. After the discharging of bin pump 1 is completed, send a feeding instruction to bin pump 1, and set the main program status position to 13. Then, receive the signal indicating that the feeding of bin pump 1 is completed or stopped. If the signal indicating that the feeding is completed is received, send a discharging instruction to bin pump 1, and set the main program status position to 16. Receive the signal indicating that the discharging of bin 1 is completed or stopped. If the stop signal is received, send a discharging instruction to each bin, and set the main program status position to 38. If the stop signal is not received, start timing according to the preset cycle waiting time. After the timing is received, set the main program status position to 17, and then control bin pump 3 to start executing the material conveying task. Or, if bin pump 1 is in the cut-off state, similarly control bin pump 3 to start executing the material conveying task. When it is monitored that bin 3 is running for the first time, send a discharging instruction to bin 3, and set the main program status position to 20. Then, receive the signal indicating that the discharging of bin 3 is completed or stopped. After the discharging of bin pump 3 is completed, send a feeding instruction to bin pump 3, and set the main program status position to 23. Then, receive the signal indicating that the feeding of bin pump 3 is completed or stopped. If the signal indicating that the feeding is completed is received, send a discharging instruction to bin pump 3, and set the main program status position to 25. Receive the signal indicating that the discharging of bin 3 is completed or stopped. If the stop signal is received, send a discharging instruction to each bin, and set the main program status position to 38. If the stop signal is not received, start timing according to the preset cycle waiting time. After the timing is received, set the main program status position to 27, and then control bin pump 5 to start executing the material conveying task. When it is monitored that bin 5 is running for the first time, send a discharging instruction to bin 5, and set the main program status position to 30. Then, receive the signal indicating that the discharging of bin 5 is completed or stopped. After the discharging of bin pump 5 is completed, send a feeding instruction to bin pump 5, and set the main program status position to 33. Then, receive the signal indicating that the feeding of bin pump 5 is completed or stopped. If the signal indicating that the feeding is completed is received, send a discharging instruction to bin pump 5, and set the main program status position to 25. Receive the signal indicating that the discharging of bin 5 is completed or stopped. If the stop signal is received, send a discharging instruction to each bin, and set the main program status position to 38. If the stop signal is not received, start timing according to the preset cycle waiting time. After the timing is received, set the main program status position to 37, and then return to control bin pump 1 to start executing the material conveying task. At this time, the running state of bin pump 1 is not the first start, so the feeding operation can be directly performed. The same applies to bin pump 3 and bin pump 5. When the running state is not the first start, directly execute the material conveying tasks of feeding and discharging and synchronously update the main program status position until the program runs to the end and set the main program status position to 0.
