DETAILED DESCRIPTION

[0011] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0013] This application provides a DCS control system based on a mine aggregate production line and aggregate sales, which can ensure the on-time delivery of large-volume orders and improve the delivery quality and operational safety of large-volume orders.

[0014] like Figure 1 As shown, a DCS control system based on a mine aggregate production line and aggregate sales includes an order demand acquisition and determination module 110, a unit attention calculation module 120, an order attention calculation module 130 and an order sorting module 140; wherein, the order demand acquisition and determination module 110 is used to obtain the order content of the order received by the system and determine the product demand mentioned in the order according to the order content, and output order demand data; the order demand data includes order delivery time, material type demand, total material demand and material transportation demand; the unit attention calculation module 120 is further configured to divide each production line unit into demand-affected units and non-demand-affected units according to the order demand data and the initial production mode of each production line unit; the production line unit represents the production unit of each functional module of the aggregate production line, including a feeding unit, a processing unit, a screening unit and a transportation unit; the preset order demand impact comparison table includes order demand data , the correspondence between each production line unit and the order demand data and the production line unit; the demand affecting unit is a production line unit that adjusts the initial production mode due to the influence of order demand; the non-demand affecting unit is a production line unit that is not affected by order demand and does not need to adjust the initial production mode; the impact attention adjustment data of the demand affecting unit is determined according to the order demand data and the preset order demand impact comparison table; the demand unit attention data of the demand affecting unit is calculated according to the basic attention data of the demand affecting unit and the impact attention adjustment data; the non-demand unit attention data of the non-demand affecting unit is calculated according to the demand unit attention data and the total attention data of the initial production line unit; the order attention calculation module 130 is used to calculate the order attention data according to the demand unit attention data and the non-demand unit attention data; the order sorting module 140 is used to determine the order processing order according to the order attention data.

[0015] It is understood that in the embodiment of the present application, the aggregate production line is divided into four units: a feeding unit, a processing unit, a screening unit, and a transportation unit. However, for different aggregate production lines, it can be divided into more or fewer units. It should be noted that the orders that need to be sorted here are all orders that meet the pre-time screening conditions; specifically, the orders that need to be sorted are determined based on the order delivery time and the preset delivery time threshold contained in the order demand data; it is understood that here, orders are screened based on the order delivery time, and orders with an order delivery time greater than the preset delivery time threshold are sorted, while orders with an order delivery time not greater than the preset delivery time threshold are sorted according to the urgency of the order delivery time; the urgency sorting here refers to determining the remaining delivery time of the order based on the order delivery time, and sorting the orders from short to long according to the remaining delivery time; and for orders with an order delivery time greater than the preset delivery time threshold, they have sufficient delivery time and are sorted according to the solution of the present application.

[0016] It can be understood that material type demand refers to the type of aggregate required by the order, such as 0-5mm machine-made sand and stone powder, 5-10mm crushed stone, 10-20mm crushed stone, 20-28mm crushed stone, four specifications of stone, etc.; since different types of aggregates require different levels of processing machines and different screening methods, in the preset order demand impact comparison table, the corresponding units associated with material type demand are processing units and screening units; and the corresponding unit associated with total material demand is the feeding unit; because the total material quantity determines the total amount of material that needs to be processed for this order, and these materials need to enter the processing unit from the feeding unit in batches for material processing, the total material quantity demand is associated with the feeding unit; and the material transportation demand is correspondingly associated with the transportation unit; it can be understood that the transportation unit here refers to the unit for transporting the material products that have been processed and screened, and does not refer to the unit for transporting unfinished materials during the processing and screening process.

[0017] It can be understood that the basic attention data for each production line unit here can be represented as the degree of computing resource allocation of the control system to each unit; for example, the basic attention data of the feeding unit is 15%, indicating that 15% of the computing resources are allocated to the feeding unit; the basic attention data of the processing unit is 40%, indicating that 40% of the computing resources are allocated to the processing unit; the basic attention data of the screening unit is 35%, indicating that 35% of the computing resources are allocated to the screening unit; the basic attention data of the transportation unit is 10%, indicating that 10% of the computing resources are allocated to the transportation unit.

[0018] Specifically, in an embodiment of the present application, the unit attention calculation module 120 is further configured to determine the impact attention adjustment data of the demand impact unit based on the order demand data and the preset order demand impact comparison table, including: determining the production operation steps included in the initial production mode corresponding to the demand impact unit based on the initial production mode of each production line unit; determining the additional operation steps based on the order demand data and the preset order demand impact comparison table; obtaining the number of steps of the additional operation steps and the preset step attention impact comparison table; determining the impact attention adjustment data of the demand impact unit based on the number of steps and the preset step attention impact comparison table; the preset step attention impact comparison table contains the correspondence between the number of steps and the impact attention adjustment data.

[0019] It can be understood that the initial production mode here is represented by the simplest production mode, the basic production mode with the least energy consumption and the least steps; and based on the order requirements, it can be determined to add additional production steps to the basic production mode; for example, the basic production mode of the feeding unit is the preset basic material quantity, which corresponds to adding materials three times in the feeding unit; the basic production mode of the processing unit is to process the stone with the largest diameter once, and the corresponding production steps are 4 steps; the basic production mode of the screening unit is to perform 1 screening; the basic production mode of the transportation unit is no need for transportation; it can be understood that the basic production mode of each production line unit illustrated in the above examples is characterized by the fact that there is no additional demand for materials in the corresponding order, so when additional demand appears in the order, such as the material type demand is greater than the preset type quantity, the total material demand is greater than the preset material quantity, and the material transportation demand is that transportation is required, the unit corresponding to the above demand is the demand-affecting unit; similarly, when there is no physical transportation demand, the transportation unit is a non-demand-affected unit.

[0020] It can be understood that since the processing method of the aggregate production line is fixed, the products that can be processed and produced are also fixed. Therefore, when the order demand is obtained, based on the total material quantity demand and material type demand in the order demand, combined with the historical processing records, the production steps that need to be added to the corresponding demand in the order demand can be determined; that is, the additional operation steps are determined according to the order demand data and the preset order demand impact comparison table; and for each additional production step, the system needs to allocate an additional portion of computing power resources to the unit, that is, the impact attention adjustment data of the demand impact unit is determined according to the number of steps and the preset step attention impact comparison table; for example, for each additional step, the attention data will be increased by 2%, etc.

[0021] Furthermore, the demand unit attention data is the sum of the basic attention data of the demand influencing unit and the influence attention adjustment data.

[0022] Furthermore, the calculation of the non-demand unit attention data of the non-demand influencing unit based on the demand unit attention data and the initial production line unit total attention data includes: calculating the demand unit total attention data based on the demand unit attention data of each demand unit; the demand unit total attention data is the sum of the demand unit attention data of each demand unit; calculating the non-demand unit total attention data based on the demand unit total attention data and the initial production line unit total attention data; the non-demand unit total attention data is the difference between the initial production line unit total attention data and the demand unit total attention data; calculating the non-demand unit attention data of the non-demand influencing unit based on the non-demand unit total attention data and the basic attention data of the non-demand unit.

[0023] In the embodiment of the present application, it should be noted that the unit attention calculation module 120 is further configured to have x demand-affecting units and y non-demand-affecting units; then, ; Then the basic attention data of the u-th demand influence unit is ; The basic attention data of the vth non-demand influence unit is ;but, in, .

[0024] The calculation method of the non-demand unit attention data includes: There are n non-demand impact units. , then the basic attention data of the i-th non-demand influence unit is ; ; Where, is the non-demand unit attention data of the i-th non-demand impact unit, is the total attention data of the demand unit; the total attention data of the initial production line unit is 1.

[0025] It can be understood that in the embodiment of the present application, the computing power resources of the system are considered to be fixed. Therefore, when the attention of any unit increases, the corresponding computing power resources will also increase; the attention of some units in the remaining units will decrease, and the corresponding computing power resources will also decrease.

[0026] After obtaining the attention data of each unit corresponding to each order, the order attention data can be calculated in combination with the preset unit attention score; and then the order processing order is obtained by sorting the order attention data from high to low.

[0027] It can be understood that the preset unit attention scores of different units are different. Therefore, through the calculation formula, the demand unit attention data of the demand-influencing units contained in the order * the corresponding preset unit attention score + the non-demand unit attention data of the non-demand-influencing units contained in the order * the corresponding preset unit attention score = order attention data.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required for this application.
