Description

Technical Field

[0001] The present application relates to the technical field of process industry, and more particularly, to a method, device and electronic device for controlling the material transportation of a pneumatic conveying device. Background Art

[0002] A pneumatic conveying device, also known as a pneumatic transportation device, is a device widely used in process industries such as petroleum, chemical, and pharmaceutical industries. It mainly consists of a series of silos, pipelines, rotary valves, reversing valves, gas source stations, feeders, dust collectors, etc. Its function is to convey powdery or granular materials in a closed pipeline along the gas flow direction under the action of gas pressure, and it has the characteristics of large conveying capacity, long conveying distance, and high conveying speed.

[0003] Currently, for the control of existing pneumatic conveying devices, the pneumatic conveying and bin switching operations are mainly carried out through a simple sequence control program. To avoid conflicts in bin selection, only one target bin can be selected simultaneously in the overall control logic, and during a single pneumatic conveying process, only a single target bin can be fed until the feeding of the target bin is completed, and then the next target bin is selected for pneumatic conveying. This relatively simple control mode is obviously not applicable in large pneumatic conveying devices, with low automation control efficiency, prone to more operation problems, and increasing the monitoring burden.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0044] In the following description, the terms "first" and "second" are only for the purpose of description and cannot be understood as indicating or implying relative importance. The following description provides multiple embodiments of the present application, and different embodiments can be replaced or combined. Therefore, the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing all other possible combinations of A, B, C, and D, although such an embodiment may not be explicitly described in the following content.

Changes may be made to the function and arrangement of the elements described without departing from the scope of the content of this application. Various processes or components may be appropriately omitted, substituted, or added to each example.

In addition, the features described for some examples may be combined into other examples.

[0046] See Figure 1 , Figure 1 is a schematic flowchart of a method for controlling the material transportation of an air-sending device provided by an embodiment of this application. In the embodiment of this application, the method includes:

[0047] S101. Determine the number of bins of the target bin, where the target bin is the selected bin that triggers the low-level warning, and the selected bin is the bin that has been selected for feeding at the current moment.

[0048] The execution subject of this application may be the cloud server corresponding to the DCS system. The Distributed Control System (DCS), also known as the distributed control system, is a new type of computer control system relative to the centralized control system. It is developed and evolved on the basis of the centralized control system. It is a multi-level computer system composed of a process control level and a process monitoring level connected by a communication network, integrating 4C technologies such as computers, communications, displays, and controls. Its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration.

[0049] In an embodiment of this application, the bin selected for feeding is the selected bin. If a certain bin is both selected and triggers a low-level warning, it will be confirmed as the target bin. The cloud server will first determine the number of bins of the target bin to facilitate deciding which method to select for feeding control in the subsequent steps. Among them, the selection of the selected bin can be made independently by the cloud server. For example, as long as there are selectable bins, it will be automatically selected as the selected bin, or it can be selected by the staff according to the actual situation from the selectable bins that need to be fed.

[0050] In an implementable manner, before step S101, it further includes:

[0051] When receiving a selection instruction for any selectable bin, determine the feeding path corresponding to the selection instruction;

[0052] When there is no conflicting path in the feeding path and the optional bin does not trigger a high-level warning, the optional bin is determined as the selected bin, and the mutually exclusive bin of the optional bin is changed to a non-selected bin. The conflicting path is a path that duplicates the feeding path of the target bin for which feeding is about to start.

[0053] When there is a conflicting path in the feeding path or the optional bin triggers a high-level warning, the selection instruction is rejected.

[0054] In an embodiment of the present application, for the case of manual selection, the staff will press the corresponding button to select the optional bin as the selected bin and assign a feeding path to it. After pressing the button, the cloud server will receive the selection instruction. To avoid the risk brought by the staff's operation errors, the conditions for the button to be operable are defined. Specifically, when all other paths that conflict with the current specific path have completed path confirmation and are about to start pneumatic conveying, or when the selection button of the current selected bin is not selected and safety protection is generated, such as when there is a high-level alarm for the selected bin, the selection operation cannot be completed. In addition, when any button among the conflicting selection buttons of the bins is pressed, the buttons corresponding to the remaining mutually exclusive bins that conflict with the selected bin will be automatically reset, changing them to non-selected bins.

[0055] S102. When the number of bins is greater than the preset number, sort the target bins based on the target bin determination time, and sequentially perform cyclic feeding on each of the target bins according to the sorting order, so that each target bin is fed for a preset duration each time.

[0056] In an embodiment of the present application, a preset number (for example, 1) is set in advance. If the number of bins is larger than the preset number, the cloud server will switch to the time mode for feeding control. In the time mode, all target bins will be sorted according to the target bin determination time of each bin, and cyclic feeding will be performed on these target bins in sequence according to the sorting order. And each target bin will only be fed for a preset duration (for example, 5 minutes) each time it is fed. This can evenly feed all bins that trigger low levels, avoid concentrating on feeding one bin, and thus prevent the situation where the materials in other bins are exhausted, ensuring the overall safety of the bin operation. Among them, the target bin determination time is the time when the bin is determined as the target bin, that is, the time when the bin simultaneously meets the conditions of being selected as the selected bin and triggering a low-level warning.

[0057] Exemplarily, if a certain bin has triggered a low-level warning and then this bin is selected as the selected bin, the time when it is selected as the selected bin simultaneously meets the two conditions, and this is the target bin determination time at this time.

[0058] Another exemplary case is that if a certain silo is first selected as the target silo and then a low-level warning is triggered during the feeding scheduling process, the moment when the low-level warning is triggered satisfies two conditions simultaneously, and this is the determination moment of the target silo.

[0059] In an implementable manner, the sorting of each of the target silos based on the determination moment of the target silo includes:

[0060] Determine the determination moments of each of the target silos corresponding to each of the target silos, and sort each of the target silos in chronological order from the earliest to the latest based on the determination moments of the target silos.

[0061] In an embodiment of the present application, the cloud server will determine the silo selection moments when each silo is selected as the target silo, sort the silo selection moments in chronological order from the earliest to the latest, and the final sorting order of the silo selection moments is the sorting order of the target silos. Since the silo selection moment is used as the sorting criterion, for a silo that has generated a low-level alarm but is not yet a target silo, the moment it is selected is the time when a valid low-level alarm is truly generated and it enters the queue. For a silo that has generated a low-level alarm but has never been selected as the target silo, it will not enter the queue for sorting.

[0062] In an implementable manner, the cyclic feeding of each of the target silos in sequence according to the sorting order, so that each of the target silos is fed for a preset duration each time, includes:

[0063] Select the first target silo according to the sorting order, feed the first target silo, and stop feeding after the feeding lasts for a preset duration. The first target silo is the target silo with the highest current sorting in the sorting order;

[0064] When a selection cancellation instruction is received, or when the first target silo has lifted the low-level warning when the feeding stops, remove the first target silo from the sorting order;

[0065] When the first target silo has not lifted the low-level warning when the feeding stops, adjust the first target silo to the last position in the sorting order;

[0066] Repeat the step of selecting the first target silo according to the sorting order.

[0067] In an embodiment of the present application, according to the sorting order, the cloud server will first select the first target bin, that is, the target bin with the highest sorting order in the sorting order, and first feed the bin. A preset duration is set in advance. After the preset duration, it is considered that the feeding process for this bin is over, so the feeding will be stopped. Then, the status of the first target bin that has just been fed will be judged. If its low-level warning has been lifted, it is considered that the materials in this bin have been temporarily replenished sufficiently. To improve the replenishment efficiency for other bins, it will be removed from the sorting order. If its low-level warning has not been lifted, it is considered that the materials in this bin can still be replenished, so it will be adjusted to the end of the sorting order and wait for the next feeding according to the sorting order. After completing the adjustment of the sorting order, the first target bin with the highest current sorting order will be rejudged and selected to continue the feeding process for each bin. In addition, when the button selection for this target bin by the staff is cancelled, a cancellation instruction will be generated. After the cloud server receives the cancellation instruction, it will also remove it from the sorting order.

[0068] In an implementable manner, the method further includes:

[0069] When the target bin does not exist in the sorting order, repeat the step of determining the number of bins of the target bin.

[0070] In an embodiment of the present application, when the target bin does not exist in the sorting order, it is considered that all target bins have been replenished to lift the low-level warning, and the feeding process has been completed. At this time, the cloud server will repeat the first step, that is, the process of determining the number of bins to select the feeding control method.

[0071] S103. When the number of bins is equal to the preset number, feed the target bin until the target bin triggers a high-level warning.

[0072] In an embodiment of the present application, the preset number is generally 1. Therefore, when the number of bins is equal to the preset number, it is considered that only one target bin needs to be fed. At this time, the cloud server will switch to the low-level feeding mode for feeding control. In the low-level feeding mode, since there are no multiple target bins that need to be evenly fed to ensure the overall demand, the target bin will be directly fed until it triggers a high-level warning and then the feeding stops, completing the feeding for this target bin.

[0073] In an implementable manner, step S103 includes:

[0074] When the number of bins is equal to the preset number, feed the target bin;

[0075] When the low material level warning corresponding to the target silo disappears, determining the number of the silos at the time when the low material level warning disappears;

[0076] When the number of silos at the time when the low material level warning disappears is zero, continue feeding material to the target silo until the target silo triggers a high material level warning, stop feeding material, and execute the step of determining the number of silos in the target silo;

[0077] When the number of the silos at the time when the low material level warning disappears is equal to one, executing the step of feeding the material to the target silo until the target silo triggers a high material level warning;

[0078] When the number of the silos at the time when the low material level warning disappears or the number of the silos during the feeding process is greater than one, the step of sorting the target silos based on the target silo determination time is executed, and cyclically feeding the target silos in sequence according to the sorting order is performed to ensure that each target silo is fed for a preset time each time.

[0079] In one embodiment of the present application, when the number of silos is only a preset number and the target silo is fed directly, its material level will be monitored. When the low material level warning disappears after feeding, a judgment will be made first to determine the number of silos corresponding to the moment when the low material level warning disappears. If the number of silos is 0, it means that after a period of feeding, after the low material level warning disappears, there is still no other target silo that has triggered the low material level warning. At this time, the target silo will continue to be fed until it triggers the high material level warning. If the number of silos at this moment is one, it is considered that there is a new target silo that has triggered the low material level warning. Since the low material level warning has been released in this silo, it is considered that the feeding process of the newly appeared target silo has higher priority, and the control process of step S103 will be executed for the newly appeared silo. If the number of silos at this moment is greater than one, or the number of silos during the feeding process when the low material level warning has not been released in the target silo is greater than one, it is considered that there are multiple new target silos that have triggered the low material level warning. In order to ensure the overall feeding situation, the control process of step S102 will be directly executed to control the feeding of all current target silos.

[0080] In one embodiment, the method further comprises:

[0081] When the number of the silos is zero, searching for the selected silo that has not triggered a low material level warning;

[0082] When there is a selected silo that has not triggered a low material level warning, feeding material to the silo that has not been fed with material until the silo that has not been fed with material triggers a high material level warning;

[0083] When there is no selected bin that has not triggered a low-level warning, repeat the step of determining the number of bins of the target bin.

[0084] In an embodiment of the present application, if the number of bins is 0, there will be two control modes. First, the cloud server will check whether there is a selected bin that has not been fed. If there is, switch to the first feeding mode, that is, give the bin a replenishment to the high level. If not, repeat the process of judging the number of bins in the first step. In addition, during the feeding process in the first feeding mode, if a new target bin is generated and this bin is not the currently feeding target bin, end the current feeding and jump to the low-level feeding mode. If there is a target bin that generates a low-level alarm and this bin is the currently feeding target bin, directly jump and enter the low-level feeding mode.
