[0032] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0033] The "Internet of Things technology" in this invention is an extension and expansion based on the Internet technology; its user end extends and expands to any object and any object to exchange information and communicate. Therefore, the definition of Internet of Things technology is: through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing devices, according to the agreed protocol, any object is connected to the Internet for information exchange and communication to achieve intelligent identification, positioning, tracking, monitoring and management. A network technology is called Internet of Things technology.

[0034] In the present invention, the speed of the production line and the processing equipment therein is controlled by the speed of the conveying line, and the conveying speed is controlled below the fastest speed that the processing equipment can process.

[0035] An embodiment of the present invention provides an Internet of Things controlled production method, which obtains a conveying efficiency-energy consumption line to reasonably configure the relationship between the conveying efficiency and energy consumption of the production line, that is, to ensure that the production line uses more reasonable energy consumption to produce products efficiently.

[0036] In order to achieve the above technical effects, the overall idea of ​​this application is as follows: S1, calculating the time period for each conveyor line to complete a preset number of products and the conveying efficiency corresponding to the time period, and obtaining a conveying efficiency-energy consumption line, wherein the conveying efficiency-energy consumption line is not a straight line; S2, according to the required production quantity and production period, obtain the minimum conveying efficiency, obtain the conveying efficiency-energy consumption line of each production line, and obtain the final conveying efficiency corresponding to the minimum energy consumption that is X percentage greater than the minimum conveying efficiency, where X is a preset parameter; S3, sorting the minimum energy consumption of each conveyor line, and configuring the production time of the production line in ascending order of the minimum energy consumption until the required production quantity can be completed within the production period.

[0037] In summary, this application confirms the effective part on the transportation efficiency-energy consumption line according to the required transportation efficiency, and makes decisions on the effective part to ensure that the production target can be achieved within the production period while minimizing energy consumption.

[0038] In order to better understand the above technical solution, a detailed description is given below in conjunction with specific implementation methods.

[0039] See also Figure 1 As shown, an embodiment of the present invention provides an assembly line batching and conveying control method and device based on the Internet of Things, which includes multiple conveying lines for producing products, which include processing equipment with different processing functions, and the steps include at least: S1, calculating the time period for each conveyor line to complete a preset number of products and the conveying efficiency corresponding to the time period, and obtaining a conveying efficiency-energy consumption line, wherein the conveying efficiency-energy consumption line is a non-linear line.

[0040] Specifically, a conveyor line is selected, and the Internet of Things is used to improve or reduce the conveying efficiency of the conveyor line, increase or reduce the processing efficiency of the equipment therein, and obtain the number of products produced and the energy consumed at different conveying speeds, that is, the total energy consumption for conveying and production is the energy consumption. It should be noted that in addition to the above-mentioned calculation method, other methods that can obtain the relationship between conveying efficiency and energy consumption at different conveying speeds under the control of the Internet of Things are also acceptable.

[0041] S2, according to the required production quantity and production period, obtain the minimum conveying efficiency, obtain the conveying efficiency-energy consumption line of each production line, and obtain the final conveying efficiency corresponding to the minimum energy consumption that is X percentage greater than the minimum conveying efficiency, where X is a preset parameter; S3, sorting the minimum energy consumption of each conveyor line, and configuring the production time of the production line in ascending order of the minimum energy consumption until the required production quantity can be completed within the production period.

[0042] Specifically, after the manufacturer signs the contract, according to the time and quantity requirements of the contract, it can be determined how much time the production line needs to produce and how many products it needs to produce, and then the minimum transmission speed on the production line, that is, the minimum transmission efficiency. As long as the transmission line speed of the production line is not lower than the minimum transmission efficiency in actual production, the production task can be completed.

[0043] However, when a conveying efficiency not lower than the minimum conveying efficiency is selected for different production lines in step S3, it is possible that a production line selects a higher transmission efficiency and the number of products produced per unit time is higher than the minimum conveying efficiency. As a result, the actual conveying efficiency of the entire factory is generally greater than the minimum conveying efficiency, and the production of products is finally completed ahead of schedule. In this way, time is not maximized and its energy consumption is not minimized. Therefore, the present invention selects the minimum energy consumption of X percentage of the minimum conveying efficiency. X is a preset number that can ensure that the required number of products can be completed within the deadline.

[0044] In one embodiment, Figure 2As shown, there are three production lines, A, B, and C. When the minimum conveying efficiency is 100 pieces / minute, A has the lowest energy consumption at a rate of 120 pieces / minute, B has the lowest energy consumption at a rate of 100 pieces / minute, and C has the lowest energy consumption at a rate of 100 pieces / minute. If the three production lines are transmitted at the above rates, the production of the products will be completed in advance, and the energy consumption is also the energy consumption corresponding to the above rates. If the minimum conveying efficiency is set to 90% of 100 pieces / minute, that is, 90 pieces / minute, A has the lowest energy consumption at a rate of 120 pieces / minute, B has the lowest energy consumption at a rate of 90 pieces / minute, and C has the lowest energy consumption at a rate of 90 pieces / minute. Tracking the average, the conveying efficiency of the three production lines is 100 pieces / minute, which just completes the target within the deadline, and the energy consumption corresponding to the lower rate, tracking the maximum utilization of time and reducing energy consumption. Optionally, the percentage of X is a real number greater than 0.

[0045] Preferably, the conveying efficiency-energy consumption line has at least two concave points, so that when the X percentage is less than 1 and is in the middle of the concave point or on the left side of the graph, the conveying efficiency corresponding to the minimum energy consumption can be selected, so that the average transmission efficiency of the production line similar to the above embodiment is the minimum conveying efficiency, thereby realizing a solution that maximizes the use of time and reduces energy consumption.

[0046] Further, step S1 includes: S101, confirm the selected conveyor line, and improve the conveying efficiency of the selected conveyor line in stages through IoT control, and obtain the energy consumption of the conveyor line in each stage; S102, obtaining a conveying efficiency-energy consumption line according to the conveying efficiency and energy consumption of the conveying line at different stages.

[0047] Specifically, improving the transmission efficiency and energy consumption in a linear manner through the Internet of Things requires more computing resources and a longer time to measure all the transmission efficiencies, which is too time-consuming and energy-consuming. Therefore, it is optional to improve the transmission efficiency in stages and measure the energy consumption, thereby reducing energy consumption and measurement time.

[0048] In one embodiment, the delivery efficiency is from 0 / min to 1000 / min. The energy consumption of a single product under the delivery efficiency of 10, 20, 30 ... 1000 / min can be calculated with a smaller granularity, with every 10 / min as a stage. It can also be calculated with a larger granularity, with every 100 minutes as a stage, 100, 200, 300 ... 1000 / min delivery efficiency, The energy consumption of a single product under the delivery efficiency of 100, 200, 300 ... 1000 / min. Under the two granularities of this embodiment, it can be easily concluded that the smaller granularity needs to be tested 100 times. Although the number of tests is large, the curve is relatively smooth and more accurate. The larger granularity needs to be tested 10 times, with a small number of tests, but the curve is steeper and imprecise. Therefore, in other embodiments, the granularity can be reasonably set according to demand to meet certain test times, accuracy and other requirements.

[0049] In one embodiment, step S2 includes S201, obtaining the minimum delivery efficiency according to the required production quantity and production deadline; S202, obtaining a valid portion of the transmission efficiency-energy consumption line that is greater than the minimum transmission efficiency by X percentage, where X is a preset parameter; S203, obtaining the lowest point of the energy consumption of the effective part, obtaining the minimum energy consumption, and confirming the transmission efficiency corresponding to the lowest point.

[0050] Specifically, if Figure 3 As shown in the diagram of the transmission efficiency-energy consumption line, the lowest transmission efficiency X percentage is taken as the dividing point. The transmission efficiency on the left cannot meet the required production quantity and production period. Therefore, the transmission efficiency on the right is selected, and the entire curve on the right is available for selection. In the present invention, the transmission efficiency corresponding to the lowest energy consumption efficiency is selected.

[0051] In one embodiment, step S3 includes: S301, sorting the minimum energy consumption of each conveying line, and sorting the conveying lines according to the minimum energy consumption; S302, according to the production deadline, the production time of the production line with the minimum energy consumption is preferentially arranged until the required production quantity can be completed within the production deadline.

[0052] Referring to the aforementioned setting of the X percentage, when the X percentage is set to a large value or is not very precise, it is possible that a production line will choose a higher transmission efficiency and the number of products produced per unit time will be higher than the minimum transmission efficiency. As a result, the actual transmission efficiency of the entire manufacturer is generally greater than the minimum transmission efficiency, and the production of the products is ultimately completed ahead of schedule. In this way, time is not utilized to the maximum extent, and its energy consumption is not minimized. In this embodiment, another technical solution for utilizing excess time is proposed, that is, the production lines are sorted according to energy consumption, and production lines with lower energy consumption are given priority to complete the production target of the production line, and then production is arranged again to guide the achievement of the target. Through the repeated use of such production lines, the use of time can also be optimized to achieve the minimum energy consumption production requirement of the required number of products.

[0053] Specifically, there are three production lines, A, B, and C. When the minimum conveying efficiency is 100 pieces / minute, the lowest energy consumption of A at a rate of 120 pieces / minute is Za, the lowest energy consumption of B at a rate of 100 pieces / minute is Zb, and the lowest energy consumption of C at a rate of 100 pieces / minute is Zc. Za>Zb>Zc, and the percentage of X is set to 100%. As mentioned above, the production of the product must be completed before the deadline. Therefore, in this embodiment, priority is given to arranging production line C in the manner of lowest energy consumption and producing within the deadline. In addition to the products produced by production line C, the remaining number of products is first arranged in the same way for production line B with lower energy consumption, and finally the surplus is obtained except for the products produced by production lines B and C, and these surpluses are arranged for production by production line A.

[0054] It should also be noted that if the X percentage is too large, it will lead to a faster selected delivery efficiency, thereby being able to complete the scheduled deadline and produce a sufficient number of products ahead of schedule. Optionally, step S3 further includes: Step S303', adding up the total production numbers produced by all production lines according to the production deadline, and when the total production number is less than the required production number, obtaining the difference between the total production number and the required production number.

[0055] Step S303', when the difference is greater than the preset value, increase the value of X and repeat steps S2-S3.

[0056] Specifically, if the percentage X is too small, the selected conveying efficiency will be slow, and thus a sufficient number of products cannot be produced within the predetermined period. Therefore, step S3 further includes: Step S303, superimpose the total production quantity produced by all production lines according to the production deadline. When the total production quantity is less than the required production quantity, increase the value of X and repeat steps S2-S3.

[0057] Specifically, step S3 also includes: Step S3031, superimpose the total production quantity produced by all production lines according to the production deadline, and when the total production quantity is less than the required production quantity, obtain the difference between the total production quantity and the required production quantity.

[0058] Step S3032, when the difference is less than a preset value, select at least one production line with the smoothest transmission efficiency-energy consumption line, and add the difference to the production line according to the production deadline, that is, increase its transmission efficiency.

[0059] For example, there are three production lines, A, B, and C. When the lowest conveying efficiency is 100 pieces / minute, the lowest energy consumption of A at a rate of 120 pieces / minute is Za, the lowest energy consumption of B at a rate of 100 pieces / minute is Zb, and the lowest energy consumption of C at a rate of 100 pieces / minute is Zc. Za>Zb>Zc. If the X percentage is set to 50%, it cannot complete the production task within the deadline. At this time, the conveying efficiency of the three production lines has been arranged. If you want to recalculate, you need to recalculate on the current basis. Therefore, this example chooses to calculate the number of products left, and then improves the conveying efficiency of at least one production line to achieve the production of products within the deadline. Improving the conveying efficiency will increase its energy consumption. Therefore, choose the production line with the smoothest conveying efficiency-energy consumption line, so that the energy consumption increase is the least.

[0060] It should be noted that the smoothing here refers to the line between the current coordinate point and the target coordinate point on the transmission efficiency-energy consumption line, rather than the tangent line of the transmission efficiency-energy consumption line.

[0061] In one embodiment, in addition to arranging the conveying efficiency of each production line, the efficiency of the processing equipment on each production line can also be arranged. The present invention further includes the following steps: Step S4, obtaining a processing efficiency-energy consumption line of a processing equipment at different processing efficiencies; Step S5, obtaining the minimum conveying efficiency of the processing equipment according to the conveying efficiency configured for the production line where the processing equipment is located; Step S6, obtaining the processing efficiency-energy consumption line of the processing equipment, and obtaining the final processing efficiency corresponding to the minimum energy consumption that is X percentage greater than the minimum driving efficiency, where X is a preset parameter; Step S7, allocate all processing equipment on the production line according to steps S4-S6.

[0062] Specifically, a production line includes multiple processing equipment. After confirming the conveying efficiency of the production line in steps S1-S3, the processing efficiency of each processing equipment on the production line can also be confirmed one by one. The confirmation method is similar to that of confirming the conveying efficiency of the production line, which will not be repeated here.

[0063] In addition to the above solution, the present invention also provides an embodiment, which includes: Step S4', obtaining a processing efficiency-energy consumption line of a processing equipment at different processing efficiencies; Step S5', obtaining the most economical conveying efficiency corresponding to the lowest energy consumption of the processing efficiency-energy consumption line; Step S6', according to the ratio of the conveying efficiency of the equipment required by the final conveying efficiency planned for the production line to the most economical conveying efficiency, add processing equipment until the total conveying efficiency of this type of processing equipment is greater than the required conveying efficiency of the equipment.

[0064] In another embodiment, in addition to processing equipment, the production line may also include equipment that requires manpower to operate. Since the efficiency of manpower operating equipment in different shifts is different, the Internet of Things cannot be effectively arranged. The present invention provides an arrangement method including: For multiple manual operations of manual equipment, obtain the conveying efficiency and energy consumption of the production teams corresponding to the manual equipment in different shifts, and arrange the production teams corresponding to the shifts according to the minimum energy consumption.

[0065] Furthermore, the production task may be adjusted, such as increasing or decreasing the number of products, so it may also include the following steps: S4', configuring the conveying efficiency of the production line according to a preset fluctuation range.

[0066] S5', when new production tasks appear, smoothly adjust the delivery efficiency of each production line.

[0067] Specifically, after the transmission efficiency is determined, the transmission efficiency is slowly increased by a certain amount. After reaching a preset peak value, the transmission efficiency is slowly decreased by a certain amount. As long as the average transmission efficiency is the determined transmission efficiency, it will be fine.

[0068] In one embodiment, multiple production lines may have to stop when the set production time is reached. In another embodiment, the products are directly produced according to the non-zero conveying efficiency corresponding to the minimum energy consumption of the entire conveying efficiency-energy consumption line. Each product produced in this way is produced with the lowest energy consumption and can be used as a substitute for defective products or as inventory for the next production task. Furthermore, a reserve warehouse is added behind these processing equipment with higher processing efficiency or production lines with higher conveying efficiency, and the reserve warehouse is used to store products or semi-finished products that exceed the planned tasks.

Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage and optical storage, etc.) containing computer-usable program codes.
