Description

Technical Field

[0001] The present invention relates to the technical field of process industry, and particularly to a material scheduling method, device and electronic equipment based on a large storage tank area. Background Art

[0002] In large multi-workshop factories in the fine chemical and pharmaceutical industries, a "material center" is often established to manage the incoming and outgoing of production raw materials. The liquid material storage tank area is the largest raw material storage place in the "material center" and is also the main source of raw materials for workshop production. When the workshop produces, it will request feeding from the "material center", and the "material center" will feed according to the requirements of the workshop. After the feeding is completed, it will calculate with the workshop according to the feeding quantity. Therefore, when multiple workshops need to be fed simultaneously, on the one hand, it is necessary to ensure that the workshop is not fed wrongly, and on the other hand, the feeding efficiency must be ensured. The feeding method can be divided into three stages of development. In the first stage, the workshop directly calls the "material center" with a walkie-talkie, asking the material center to start the pump and open the valve. When the cumulative value of the flowmeter reaches, the feeding stops. This method mainly relies on manual work, and it is easy to make mistakes in starting equipment, resulting in the problem of feeding the wrong workshop; there will also be a problem of missing the feeding of some workshops when multiple workshops request at the same time. In the second stage, with the popularization of DCS, the "material center" and the production workshop directly exchange data through the DCS network. The operation station of the workshop can directly send a request to the "material center", and the "material center" starts the pump and opens the valve for feeding. However, if there is a situation where another workshop is feeding the same material, the request can only be made later. This method will not feed the wrong workshop, but the efficiency is low. In the third stage, after the improvement of the DCS feeding algorithm, it currently has a queuing function. When multiple workshops request materials from the "material center", they will automatically queue up at the "material center". This method solves the problem of feeding the wrong workshop, and the efficiency has also been improved to a certain extent, but the following problems still remain unsolved. First, when multiple workshops request the same material at the same time, even if the transfer pump has the ability to feed multiple workshops at the same time, according to the queuing rule, only one workshop can be fed each time, and the efficiency is still not maximized; second, if a certain workshop needs to use materials urgently, the operator cannot intervene and can only queue according to a single rule, and scheduling cannot be achieved. Summary of the Invention

[0003] To solve the above problems, the present invention provides a material scheduling method, device and electronic equipment based on a large storage tank area.

[0004] In the first aspect, the present invention provides a material scheduling method based on a large storage tank area, and the method includes:

[0005] Determine the current material object and the maximum number of workshops allowed to feed materials simultaneously, set the target number of workshops for simultaneous feeding, sort them in the order of the initialized target feeding workshops, and generate an array recording the order of the target feeding workshops;

Adjust the Nth requesting workshop to the target position of the workshops that are not currently feeding materials in the target feeding workshop order array, and mark the status of this Nth requesting workshop as "requesting" in the target feeding workshop order array;

[0007] When the feeding request of the Nth requesting workshop is satisfied, eliminate the "requesting" status, move the subsequent workshops after the Nth requesting workshop forward by one position, and update the target feeding workshop order array.

[0010] Specifically, the feeding request of the Nth requesting workshop being satisfied includes the Nth requesting workshop completing the feeding or actively canceling it, and after the request is satisfied, it exits the target feeding workshop order array.

[0011] Specifically, the marked statuses of all target workshops in the array of the target feeding workshop order also include "feeding", "requesting", and "waiting".

[0030] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0031] See Figure 1 , Figure 1 is a flowchart of a material scheduling method based on a large storage tank area provided by the embodiment of the present invention. In the embodiment of the present invention, the method includes:

[0032] S110, determining the current material object and the maximum value of the number of workshops allowed to feed simultaneously, setting the target number of workshops for simultaneous feeding, and sorting in the initialized target feeding workshop sequence to generate an array recording the target feeding workshop sequence. The maximum value of the number of workshops allowed to feed simultaneously is the maximum value of the number of workshops determined according to the characteristics of the material object and the conveying capacity of the storage tank area; the set target number of workshops for simultaneous feeding is greater than or equal to one and less than or equal to the maximum value of the number of workshops allowed to feed simultaneously.

[0033] The execution entity of this application can be the cloud server corresponding to the DCS system. DCS, namely Distributed Control System, is an instrument control system based on microprocessors, adopting the design principles of decentralized control functions, centralized display and operation, and taking into account both decentralized autonomy and comprehensive coordination.

[0034] S120, receive the material feeding request of the Nth requesting workshop, where N is any workshop in the target material feeding workshop sequence array that is not currently in the process of material feeding, adjust the Nth requesting workshop to the target position of the workshops that are not currently in the process of material feeding in the target material feeding workshop sequence array, and mark the status of the Nth requesting workshop as "requesting" in the target material feeding workshop sequence array. Adjusting to the target position includes adjusting to the head of the queue of the workshops that are not currently in the process of material feeding in the target material feeding workshop sequence array, that is, setting to the top, or adjusting to any other position before the last target workshop and other workshops that are not currently in the process of material feeding in the target material feeding workshop sequence array.

[0035] S130, when the material feeding request of the Nth requesting workshop is satisfied, eliminate the "requesting" status, move the subsequent workshops behind the Nth requesting workshop forward by one position, and update the target material feeding workshop sequence array. The material feeding request of the Nth requesting workshop being satisfied includes the Nth requesting workshop completing the material feeding or actively canceling, and after the request is satisfied, it exits the queue of the target material feeding workshop sequence array.

[0036] Taking a chemical plant's conveying of toluene material to workshops as an example, see Figures 2 to 7 . As Figure 2 shown, the toluene storage tank is in the material storage tank area, and can convey materials to "Workshop 102", "Workshop 104", "Workshop 106", "Workshop 107", "Workshop 201", "Workshop 202", "Workshop 205", "Workshop 206", "Workshop 301", "Workshop 302", "Workshop 303" and "Workshop 304" through a transfer pump. A flow meter is installed in each workshop to measure the amount of materials conveyed from the toluene tank area to each workshop. When feeding materials, the materials are queued and conveyed in the order of the request time of each workshop (first in, first out), and the transfer pump has the ability to convey materials to up to 5 workshops simultaneously. During production, the number of workshops can be set as needed, that is, adjusted between 1 and 5 for the maximum number of workshops that can be fed simultaneously each time. As Figure 3 shown, set the "simultaneous dequeue quantity" to 3, that is, the situation of feeding materials to 3 workshops simultaneously; as Figure 4 shown, set the "simultaneous dequeue quantity" to 5, that is, the situation of feeding materials to 5 workshops simultaneously.

[0037] See Figure 5, set the "simultaneous outbound quantity" to 3, that is, feed materials to 3 workshops simultaneously. After any one of the workshops "Workshop 104", "Workshop 106", and "Workshop 202" finishes feeding materials, according to the "first in, first out" rule, the next workshop to be fed is "Workshop 201". However, at this time, an emergency occurs in "Workshop 302", and it requests to be fed immediately and needs to be given top priority. Then, the "current queue number" is selected as 7 (i.e., the current position of Workshop 302 in the queue), and the "top" button is pressed to adjust its queue position to the current 4th position, that is, the queue position where "Workshop 201" is located. The adjusted target feeding workshop sequence array queue is as Figure 3 shown. "Workshop 302" is ranked 4th in the queue. The workshops originally in the 4th to 6th positions in the queue all move back one position, and the positions of the 3 workshops that are currently being fed remain unchanged, realizing the top operation of Workshop 302.

[0038] See Figure 6 , set the "simultaneous outbound quantity" to 1. "Workshop 104" is in the process of feeding materials. According to the on-site situation, "Workshop 206" needs to be ranked in the position where "Workshop 202" is located, that is, adjusted from the 6th position to the 3rd position. Then, on the control panel, set the "current queue number" to 6 (the current position of Workshop 206 in the queue), set the "target queue number" to 3 (the current position of Workshop 202 in the queue), and press the "cut in" button to adjust "Workshop 206" to the 3rd position in the queue, as Figure 7 shown. The workshops originally in the 4th to 6th positions in the queue all move back one position, and queues 1 and 2 as well as 7 to 9 remain unchanged, realizing the cut-in operation of Workshop 206.

[0039] See Figure 8 , Figure 8 is a schematic structural diagram of a material scheduling device based on a large storage tank area provided by an embodiment of the present invention. As Figure 8 shown, the device includes:

[0040] A determination module 210, configured to determine the current material object and the maximum number of workshops allowed to feed materials simultaneously, set the target number of workshops to feed materials simultaneously, and sort them in the order of the initialized target feeding workshop sequence to generate an array recording the target feeding workshop sequence;
