Description

Technical Field

[0001] The embodiments of the present invention generally relate to the field of automatic raw material monitoring technology, and particularly to methods, apparatus and equipment for automatic raw material monitoring based on the Industrial Internet of Things. Background Technology

[0002] In today's increasingly competitive market, building a sound and scientific internal supervision system has become a core requirement for enterprises to achieve sustainable development, a need that is particularly prominent for manufacturing companies. Manufacturing companies, whose main business is production, inevitably involve the storage and turnover of large amounts of raw materials in their production processes, often requiring multiple production workshops and warehouse spaces, leading to continuously rising costs related to space and management. In this context, if a company cannot effectively supervise raw materials and related production processes, it will directly disrupt production order, thereby seriously affecting the company's normal operation and the foundation for its development.

[0003] Currently, a common method for monitoring raw material storage workshops is to set a constant critical reserve level for raw materials. When the actual inventory of raw materials in the workshop falls below this critical level, the system automatically triggers a procurement alert. However, in actual production and operation, raw material reserves are dynamically affected by various external factors, such as the stability of raw material procurement channels, fluctuations in procurement cycles, the supply capacity of the upstream supply chain, and changes in market demand. Relying solely on a fixed critical reserve level for raw material management and procurement arrangements can easily lead to reserve imbalances. Excessive reserves result in raw material stockpiling, which not only ties up significant capital and warehousing resources but also increases inventory management costs and the risk of raw material loss, directly raising the company's operating costs. Conversely, insufficient reserves lead to insufficient raw material supply, directly delaying material preparation and subsequent production progress, thus affecting order delivery efficiency and ultimately negatively impacting the company's economic benefits. Summary of the Invention

[0004] To address the above issues, this invention adjusts the critical reserve level based on the number of procurement channels, average purchase price per unit, and average procurement time interval for each type of raw material, and monitors the raw materials based on the adjusted critical reserve level.

[0022] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0023] Figure 1 This is a schematic flowchart of a method for automatic monitoring of raw materials based on the Industrial Internet of Things (IIoT) according to an embodiment of the present invention.

[0026] Step S04: Obtain the real-time reserve quantity for each type of raw material, and determine whether there is a supply shortage for the corresponding type of raw material based on the real-time reserve quantity and the second critical reserve quantity. If there is a supply shortage, generate a prompt message and send it to the raw material procurement management platform.

[0027] It should be noted that although the operation of the method of the present invention has been described in a specific order in the above embodiments and figures, this does not require or imply that the operations must be performed in that specific order, or that all the operations shown must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0028] To provide a clearer explanation of the above-mentioned method for automatic monitoring of raw materials based on the Industrial Internet of Things, a specific embodiment will be used for illustration below. However, it is worth noting that this embodiment is only for better illustrating the present invention and does not constitute an improper limitation of the present invention.

[0029] The following example will further illustrate the method of automatic monitoring of raw materials based on the Industrial Internet of Things: Step S01: Obtain the types of each raw material and the corresponding procurement information for each type of raw material.

[0030] Specifically, the system obtains the types of raw materials that are expected to be stored in the raw material storage workshop, retrieves the previous purchase lists corresponding to each type of raw material from the raw material procurement management platform, and obtains the procurement information corresponding to each type of raw material from the previous purchase lists.

[0031] The raw material procurement management platform can be a traditional procurement management platform. After successful identity verification, users can log in to the raw material procurement management platform and retrieve the previous procurement list for each type of raw material.

[0032] The procurement list includes procurement information for each type of raw material.

[0033] The procurement information includes: the number of procurement channels, the average procurement price per item, and the average procurement time interval.

[0034] In this embodiment, the raw materials include flour and wheat flour. The procurement information for flour includes: 2 procurement channels, an average purchase price of 10 yuan / jin per unit, and an average procurement time interval of 3 days. The procurement information for wheat flour includes: 3 procurement channels, an average purchase price of 8 yuan / jin per unit, and an average procurement time interval of 4 days.

[0035] Step S02: Calculate the cost percentage and critical reserve correlation factor for each type of raw material.

[0036] Specifically, the system obtains the types of materials used for each type of raw material, and retrieves the average selling price per unit for each type of material from the sales management system. Based on the average purchase price per unit for each type of raw material and the average selling price per unit for each type of material used for each type of raw material, the system calculates the cost percentage for each type of raw material.

[0037] The sales management system can adopt a traditional shipment management system. This system records detailed information about the sale of each type of material. By retrieving this detailed information, the selling price per item for each type of material can be obtained. Then, an average is calculated based on the quantity of each material type and the selling price per item for each type of material. That is, the sum of the selling prices per item for each type of material is divided by the quantity of each material type to obtain the average selling price per item for each type of material used in the preparation of each raw material.

[0038] Cost percentage for each type of raw material The calculation formula is: , in, Indicates the first The average purchase price per item for each type of raw material Indicates the first The raw material categories are used to formulate the average selling price per unit for each type of material.

[0039] The critical reserve correlation factor for each raw material type is calculated based on the number of procurement channels, average procurement time interval, and cost percentage for each type of raw material. The calculation formula is: , in, Indicates the first The critical reserve level correlation factor for each type of raw material Indicates the first The number of procurement channels corresponding to each type of raw material The benchmark value representing the number of procurement channels.

The benchmark value representing the average procurement time interval. This represents the second weight corresponding to the average procurement time interval. This represents the third weight corresponding to the cost percentage.

[0040] In this embodiment, flour is used to prepare two types of materials: bread and cake. The average selling price of each piece of bread is 30 yuan, and the average selling price of each piece of cake is 40 yuan. The average selling price of each piece of the two types of materials is (30+40) / 2=35 yuan.

[0041] Wheat flour is used to make two types of ingredients: steamed buns and noodles. The average selling price of each steamed bun is 15 yuan, and the average selling price of each noodle is 20 yuan. The average selling price of each of the two types of ingredients is (15+20) / 2=17.5 yuan.

[0042] Cost breakdown by component: Flour: Wheat flour: γ = 8 / 17.5 ≈ 0.457.

[0043] Setting benchmark values ​​and weights: Benchmark value for the number of procurement channels Average procurement time interval benchmark Heaven, first weight Second weight Third weight .

[0044] Calculate the critical reserve correlation factor for each type of raw material: flour , wheat flour: .

[0045] Step S03: Obtain the first critical reserve quantity for each type of raw material, and calculate the second critical reserve quantity for each type of raw material based on the critical reserve quantity correlation factor and the first critical reserve quantity.

[0046] Specifically, the steps for obtaining the first critical reserve quantity for each type of raw material are as follows: Step S031: Within a preset time range, obtain the corresponding shipment quantity of each material used for preparation for each type of raw material, and calculate the average daily shipment quantity of each material used for preparation for each type of raw material based on the shipment quantity.

[0047] First, the total output of each material used for preparation for each raw material type is calculated within a preset time range. Then, the total output of each material used for preparation for each raw material type within the preset time range is divided by the quantity of each material type to obtain the average daily output of each material used for preparation for each raw material type. The preset time range can be selected daily according to actual conditions.

[0048] Step S032: Obtain the required quantity of each raw material in the preparation process, and calculate the average quantity of each raw material to obtain the average required quantity of each raw material.

[0049] Step S033: Calculate the average daily consumption of each raw material type based on the average daily shipment volume of each material and the average quantity required for preparation.

[0050] The formula for calculating the average daily consumption of each type of raw material is as follows: , in, Indicates the first Each raw material type corresponds to the average daily shipment volume of each material. Indicates the first The average quantity required for preparation for each type of raw material. Indicates the first Average daily consumption of each type of raw material.

[0051] Step S034: Select the minimum time interval from the procurement time intervals of each previous procurement list corresponding to each raw material type as the expedited procurement time interval for the corresponding raw material type.

[0052] Step S035: Calculate the corresponding safety stock level for each type of raw material based on the expedited procurement time interval and average daily consumption for each type of raw material.

[0053] The formula for calculating the safety stock level for each type of raw material is as follows: , in, Indicates the first The corresponding expedited procurement time intervals for each type of raw material. Indicates the first The amount of insurance reserves corresponding to each type of raw material.

[0054] Step S036: Obtain the corresponding first critical reserve for each raw material based on the safety reserve for each type of raw material.

[0055] The formula for calculating the first critical reserve for each type of raw material is as follows: , in, Indicates the first The first critical reserve level for each type of raw material. Indicates the first The average procurement time interval for each type of raw material.

[0056] The formula for calculating the second critical reserve for each type of raw material is as follows: , in, Indicates the first The first critical reserve level for each type of raw material. Indicates the first The second critical reserve level corresponding to each type of raw material. Indicates the first The critical reserve quantity correlation factor for each type of raw material.

[0057] In this embodiment, a preset time range of 30 days is set, and the shipment data is retrieved: The flour-based bread production volume is 300 pieces in 30 days, and the cake production volume is 240 pieces in 30 days. The average daily production volume is (300+240) / 30=18 pieces / day. The wheat flour-based steamed buns produced 600 units in 30 days, and the noodles produced 450 units in 30 days. The average daily output is (600 + 450) / 30 = 35 units / day.

[0058] Calculate the average quantity required for preparation: Flour: 0.5 catties is needed to make 1 loaf of bread and 0.8 catties is needed to make 1 cake. The average amount needed is (0.5 + 0.8) / 2 = 0.65 catties / loaf. Wheat flour: 0.3 jin is needed to make 1 steamed bun and 0.4 jin is needed to make 1 noodle. The average amount needed is (0.3 + 0.4) / 2 = 0.35 jin / batch.

[0059] Calculate the average daily consumption: Flour: catties / day, wheat flour: Jin / day.

[0060] Select the shortest time interval from previous procurement lists: The usual intervals for purchasing flour are 3 days, 4 days, and 2 days; the interval for expedited purchasing is 2 days. The usual procurement intervals for wheat flour are 4 days, 3 days, and 5 days, while the expedited procurement interval is 3 days.

[0061] Calculating safety reserves: Flour: Safety Reserves jin (500g), wheat flour: safety reserve catty.

[0062] Calculate the first critical reserve level: Flour: m jin, wheat flour: m jin.

[0063] Calculate the second critical reserve: Flour: 46 jin (approximately 23 catties) of wheat flour: 96 jin (approximately 43 catties).

[0064] Step S04: Obtain the real-time reserve quantity for each type of raw material, and determine whether there is a supply shortage for the corresponding type of raw material based on the real-time reserve quantity and the second critical reserve quantity. If there is a supply shortage, generate a prompt message and send it to the raw material procurement management platform.

[0065] As one possible implementation, detection equipment, such as a camera, installed in the raw material storage workshop can be used to capture images of the target inside the workshop in real time. The images can then be analyzed to detect the real-time reserve of each type of raw material stored in the workshop.

[0066] As another possible implementation, the system can retrieve the raw material storage records and raw material usage records in the raw material storage workshop to obtain the real-time reserve quantity corresponding to each type of raw material stored in the raw material storage workshop.

[0067] Specifically, the real-time reserve quantity for each type of raw material is compared with the second critical reserve quantity. If the real-time reserve quantity is less than the second critical reserve quantity, it is determined that the supply of the corresponding raw material type is insufficient, and a corresponding prompt message is generated and sent to the raw material procurement management platform to remind the procurement department to make purchases. The prompt message includes the types of raw materials that are in short supply.

[0068] Therefore, the critical reserve level can be adjusted according to the number of procurement channels, average purchase price per unit, and average procurement time interval for each type of raw material, and the raw materials can be monitored based on the adjusted critical reserve level. This can effectively avoid situations where there is insufficient supply or excessive reserves of raw materials, thereby avoiding any impact on the company's profits.

[0069] In another embodiment of the present invention, the prompt information may also include the types of raw materials that are in short supply and the required purchase quantity. That is, when it is determined that the corresponding types of raw materials are in short supply, the types of raw materials that are in short supply and the required purchase quantity can be sent to the raw material procurement management platform at the same time.

[0070] Obtaining the required procurement quantity for raw materials in short supply may specifically include the following steps: Step S041: Obtain the average daily consumption of the raw materials with insufficient supply based on the types of raw materials with insufficient supply.

[0071] Step S042: Obtain the preparation time of each material prepared for the raw material types with insufficient supply, and calculate the average value based on the preparation time of each material prepared for the raw material types with insufficient supply and the quantity of each material type. That is, divide the total preparation time by the quantity of each material type to obtain the average preparation time corresponding to each material prepared for the raw material types with insufficient supply.

[0072] Step S043: Multiply the average daily consumption of the raw material type with insufficient supply by the average preparation time of each material prepared for the raw material type with insufficient supply to obtain the required purchase quantity of the raw material type with insufficient supply.

[0073] Therefore, when it is determined that the supply of the corresponding raw materials is insufficient, the purchasing department can not only be notified to make timely purchases, but also the required purchase quantity can be accurately provided.

[0074] In this embodiment, the real-time reserve quantity is obtained through the inventory management system: the current reserve quantity of flour is 40 jin and the current reserve quantity of wheat flour is 100 jin. Flour: 40 jin < 46 jin, which is determined to be insufficient supply. Wheat flour: 100 jin > 96 jin, which is determined to be sufficient supply.

[0075] Regarding the flour shortage: Given that the average daily flour consumption is 11.7 jin / day, the bread preparation time is 2 hours, the cake preparation time is 3 hours, the average preparation time is (2+3) / 2=2.5 hours=0.104 days, the required purchase quantity is = average daily consumption × average preparation time = 11.7 × 0.104≈1.22 jin (rounded to 2 jin according to actual purchase needs).

[0076] A notification was sent to the raw material procurement management platform: The current flour reserve is 40 jin, which is lower than the second critical reserve of 46 jin. The supply is insufficient. It is recommended to purchase 2 jin to ensure production needs.

[0077] In summary, the automatic raw material monitoring method based on the Industrial Internet of Things according to embodiments of the present invention obtains the types of raw materials expected to be stored in the raw material storage workshop, retrieves the previous purchase lists corresponding to each type of raw material from the raw material procurement management platform, and obtains the procurement information corresponding to each type of raw material from the previous purchase lists; wherein, the procurement information includes: the number of procurement channels, the average purchase price per unit, and the average purchase time interval; obtains the type of material used for preparation of each type of raw material; obtains the average selling price per unit corresponding to each type of material from the sales management system; and calculates the cost corresponding to each type of raw material based on the average purchase price per unit corresponding to each type of raw material and the average selling price per unit corresponding to each type of material used for preparation of each type of raw material. This method calculates the critical reserve correlation factor for each raw material type based on the number of procurement channels, average procurement time interval, and cost percentage. It then obtains the first critical reserve for each raw material type and the second critical reserve based on the critical reserve correlation factor and the first critical reserve. Real-time monitoring of the reserve for each raw material type in the storage workshop is conducted using detection equipment. Based on the real-time and second critical reserves, the method determines whether there is a supply shortage for the corresponding raw material type and generates and sends a notification to the raw material procurement management platform when a shortage is detected. This allows for adjusting the critical reserve based on the number of procurement channels, average purchase price per unit, and average procurement time interval for each raw material type. The adjusted critical reserve is then used to monitor the raw materials, effectively preventing both insufficient supply and excessive reserves, thus avoiding any impact on company profits.

[0078] Based on the same inventive concept, this invention also proposes a device for automatic monitoring of raw materials based on the Industrial Internet of Things (IIoT). The implementation of this device can be found in the implementation of the method described above; repeated details will not be repeated.

If the supply is insufficient, it generates a prompt message and sends it to the raw material procurement management platform.
