[0058] The following further details the embodiments of the present invention with reference to the accompanying drawings.
[0059] In the present invention, the "Internet of Things technology" is an extension and expansion based on the Internet technology; its user side extends and expands to any item and item for information exchange and communication. Therefore, the definition of the Internet of Things technology is: a network technology that connects any item to the Internet through information sensing devices such as radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners, etc., according to an agreed protocol, for information exchange and communication to achieve intelligent identification, positioning, tracking, monitoring, and management is called the Internet of Things technology.
[0060] In the present invention, the speed of the production line conveyed by the conveyor line controls the speed of the production line and the processing equipment therein, and at the same time, the conveying speed is controlled below the fastest speed that the processing equipment can process.
[0061] The embodiments of the present invention provide a production method controlled by the Internet of Things, which obtains the conveyor efficiency - energy consumption line to reasonably configure the relationship between the conveyor efficiency and energy consumption of the production line, that is, to ensure that the production line uses more reasonable energy consumption for efficient product production.
[0062] To achieve the above technical effects, the general idea of the present application is as follows:
[0063] S1. Measure the time period for each conveyor line to complete the preset number of products and the corresponding conveyor efficiency during this time period, and obtain the conveyor efficiency - energy consumption line, where the conveyor efficiency - energy consumption line is non - linear;
[0064] S2. Based on the required production quantity and production deadline, obtain the minimum conveyor efficiency. On the conveyor efficiency - energy consumption line of each production line, obtain the final conveyor efficiency corresponding to the minimum energy consumption that is greater than X percentage of the minimum conveyor efficiency, where X is a preset parameter;
[0065] S3. Sort the minimum energy consumption of each conveyor line and configure the production time of the production lines in ascending order of the minimum energy consumption until the required production quantity can be completed within the production deadline.
[0066] In summary, according to the required conveyor efficiency, this application confirms its effective part on the conveyor efficiency - energy consumption line and makes decisions on the effective part to ensure that the production target can be achieved within the production deadline while minimizing energy consumption.
[0067] To better understand the above - mentioned technical solution, the following is a detailed description in combination with specific implementation manners.
[0068] See Figure 1 As shown, an embodiment of the present invention provides an Internet - of - Things - based pipeline batching and conveying control method and device, which includes multiple conveyor lines for producing products, and processing equipment with different processing functions. Its steps at least include:
[0069] S1. Measure the time period for each conveyor line to complete the preset number of products and the corresponding conveyor efficiency during this time period, and obtain the conveyor efficiency - energy consumption line, where the conveyor efficiency - energy consumption line is non - linear.
[0070] Specifically, select a conveyor line, and through the Internet of Things, increase or decrease the conveyor efficiency of the conveyor line, and increase or decrease the processing efficiency of the equipment therein, to obtain the number of products produced and the consumed energy at different conveyor 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 measurement method, other methods that can obtain the relationship between conveyor efficiency and energy consumption at different conveyor speeds under Internet - of - Things control are also applicable.
[0071] S2. Based on the required production quantity and production deadline, obtain the minimum conveyor efficiency. On the conveyor efficiency - energy consumption line of each production line, obtain the final conveyor efficiency corresponding to the minimum energy consumption that is greater than X percentage of the minimum conveyor efficiency, where X is a preset parameter;
[0072] S3. Sort the minimum energy consumption of each conveyor line and configure the production time of the production lines in ascending order of the minimum energy consumption until the required production quantity can be completed within the production deadline.
[0073] Specifically, after the manufacturer signs a contract, according to the time and quantity requirements of the contract, it can be obtained how many products the production line needs to produce within a certain period of time, and then the minimum transmission speed of the production line, that is, the minimum conveying efficiency, can be obtained. Then, as long as the conveying speed of the conveyor line on the production line is not lower than the minimum conveying efficiency during actual production, the production task will surely be completed.
[0074] However, when selecting a conveying efficiency not lower than the minimum conveying efficiency for different production lines in step S3, it is possible that a production line selects a higher transmission efficiency, and thus 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 manufacturer is generally greater than the minimum conveying efficiency, and the production of products is ultimately completed ahead of schedule. In this way, time is not maximally utilized, and its energy consumption is not minimized. Therefore, the present invention selects the minimum energy consumption at X percentage of the minimum conveying efficiency. X is a preset value that can ensure the number of required products is completed within the deadline.
[0075] In one embodiment, as Figure 2 shown, there are a total of 3 production lines, namely A, B, and C. When the minimum conveying efficiency is 100 pieces per minute, the energy consumption of A is the lowest at a speed of 120 pieces per minute, the energy consumption of B is the lowest at a speed of 100 pieces per minute, and the energy consumption of C is the lowest at a speed of 100 pieces per minute. If the three production lines are respectively transmitted at the above speeds, the production of products will be completed ahead of schedule, and at the same time, the energy consumption is also the energy consumption corresponding to the above speeds. If the minimum conveying efficiency is set to 90% of 100 pieces per minute, that is, 90 pieces per minute, the energy consumption of A is the lowest at a speed of 120 pieces per minute, the energy consumption of B is the lowest at a speed of 90 pieces per minute, and the energy consumption of C is the lowest at a speed of 90 pieces per minute. On average, the conveying efficiency of the three production lines is 100 pieces per minute, just completing the target within the deadline, and the energy consumption is the energy consumption at the lower speed corresponding to it, tracking to maximize the utilization of time and reduce energy consumption. Optionally, the X percentage is a real number greater than 0.
[0076] Preferably, the conveying efficiency - energy consumption line has at least 2 concave points. In this way, when the X percentage is less than 1 and the value is relatively small, and when it is in the middle of the concave points or on the left side of the graph, a conveying efficiency higher than the conveying efficiency corresponding to the minimum energy consumption can be selected. In this way, the average transmission efficiency of the production line in a similar above - mentioned embodiment is the minimum conveying efficiency, thus realizing the scheme of maximizing the utilization of time and reducing energy consumption.
[0077] Further, step S1 includes:
[0078] S101, confirm the selected conveyor line, and through Internet of Things control, gradually increase the conveying efficiency of the selected conveyor line to obtain the energy consumption of the conveyor line at each stage.
[0079] S102. Obtain the throughput efficiency - energy consumption line according to the throughput efficiency and energy consumption of the conveyor line at different stages.
[0080] Specifically, to linearly improve the throughput efficiency and energy consumption through the Internet of Things, a large amount of computing resources and a long time are required to measure all throughput efficiencies, which is too time-consuming and energy-consuming. Therefore, optionally, the throughput efficiency can be improved in stages at different throughput efficiencies, and the energy consumption can be measured, thereby reducing the energy consumption and measurement time.
[0081] In one embodiment, when the throughput efficiency ranges from 0 units / minute to 1000 units / minute, the energy consumption of single product transmission and production at throughput efficiencies of 10, 20, 30... 1000 units / minute can be measured in smaller granularity with a stage of every 10 units / minute, or the energy consumption of single product transmission and production at throughput efficiencies of 100, 200, 300... 1000 units / minute can be measured in larger granularity with a stage of every 100 units / minute. In the two granularities of this embodiment, it can be very easily obtained that the smaller granularity requires 100 tests. Although the number of tests is large, the curve is smoother and more accurate. The larger granularity requires 10 tests, with fewer tests, but the curve is steeper and less accurate. Therefore, in other embodiments, the granularity can be reasonably set according to requirements to meet certain test times, accuracy, and other requirements.
[0082] In one embodiment, step S2 includes
[0083] S201. Obtain the minimum throughput efficiency according to the required production quantity and production period.
[0084] S202. Obtain the effective part of the throughput efficiency - energy consumption line that is greater than X percentage of the minimum throughput efficiency, where X is a preset parameter.
[0085] S203. Obtain the lowest point of the energy consumption of the effective part to obtain the minimum energy consumption, and confirm the throughput efficiency corresponding to the lowest point.
[0086] Specifically, as Figure 3 shown, in the graph of the throughput efficiency - energy consumption line, taking X percentage of the minimum throughput efficiency as the demarcation point, the throughput efficiency on the left cannot meet the required production quantity and production period. Therefore, select the throughput efficiency on the right, and the entire curve on the right is available for selection. In the present invention, just select the throughput efficiency corresponding to the point with the lowest energy consumption efficiency.
[0087] In one embodiment, step S3 includes:
[0088] S301. Sort the minimum energy consumption of each conveyor line, and sort the conveyor lines according to the magnitude of the minimum energy consumption.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] 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.
[0093] Optionally, step S3 further includes:
[0094] 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.
[0095] Step S303', when the difference is greater than the preset value, increase the value of X and repeat steps S2-S3.
[0096] Specifically, if the X percentage is selected to be too small, it will result in a slow selected conveying efficiency, and thus it will be impossible to produce a sufficient number of products within the scheduled period. Therefore, step S3 further includes:
[0097] Step S303, add up the total number of products produced by all production lines according to the production period. When the total number of products produced is less than the required number of products, increase the value of X, and repeat steps S2 - S3.
[0098] Specifically, step S3 further includes:
[0099] Step S3031, add up the total number of products produced by all production lines according to the production period. When the total number of products produced is less than the required number of products, obtain the difference between the total number of products produced and the required number of products.
[0100] Step S3032, when the difference is less than a preset value, select at least one production line with the smoothest conveying efficiency - energy consumption line, and add the difference to the production line according to the production period, that is, increase its conveying efficiency.
[0101] For example, there are a total of 3 production lines, A, B, and C. When the minimum conveying efficiency is 100 pieces per minute, the minimum energy consumption of A at a rate of 120 pieces per minute is Za, the minimum energy consumption of B at a rate of 100 pieces per minute is Zb, and the minimum energy consumption of C at a rate of 100 pieces per minute is Zc, where Za > Zb > Zc. Suppose the X percentage is set at 50%, and it cannot complete the production task within the time limit. At this time, the conveying efficiency of all 3 production lines has been arranged. If recalculated, it needs to be recalculated based on the current situation. Therefore, in this example, it is selected to calculate how many products are still left, and then the production of products within the time limit is achieved by increasing the conveying efficiency in at least one production line. And increasing the conveying efficiency will increase its energy consumption. Therefore, the production line with the smoothest conveying efficiency - energy consumption line is selected, so that the increase in energy consumption is the least.
[0102] It should be noted that the smoothness here refers to the line connecting the current coordinate point and the target coordinate point on the conveying efficiency - energy consumption line, rather than the tangent of the conveying efficiency - energy consumption line.
[0103] 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:
[0104] Step S4, obtain the processing efficiency - energy consumption line of a processing equipment at different processing efficiencies;
[0105] Step S5, according to the conveying efficiency configured for the production line where the processing equipment is located, obtain the minimum conveying efficiency of the processing equipment;
[0106] Step S6, obtain the final processing efficiency corresponding to the minimum energy consumption with an X percentage greater than the minimum driving efficiency on the processing efficiency - energy consumption line of the processing equipment, where X is a preset parameter;
[0107] Step S7, allocate all the processing equipment on the production line according to Steps S4 - S6.
[0108] 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 and will not be elaborated here.
[0109] In addition to the above solution, the present invention also provides an embodiment, which includes:
[0110] Step S4', obtain the processing efficiency - energy consumption line of a processing equipment at different processing efficiencies;
[0111] Step S5', obtain the most energy - saving conveying efficiency corresponding to the minimum energy consumption of the processing efficiency - energy consumption line;
[0112] Step S6', according to the ratio of the conveying efficiency required by the final conveying efficiency planned for the production line to the most energy - saving conveying efficiency of the equipment, increase the processing equipment until the total conveying efficiency of this type of processing equipment is greater than the required conveying efficiency of the equipment.
[0113] In another embodiment, in addition to processing equipment, the production line may also include equipment that requires manual operation. Since the efficiency of manual operation equipment in different shifts is different, the Internet of Things cannot effectively arrange it. The present invention provides an arrangement method, which includes:
[0114] For the manual equipment with multiple manual operations, obtain the conveying efficiency and energy consumption of the production team corresponding to the manual equipment in different shifts, and arrange the production teams corresponding to the shifts according to the minimum energy consumption.
[0115] Furthermore, production tasks may be adjusted, such as increasing or decreasing the number of products. Therefore, it may also include the following steps:
[0116] S4', configure the conveying efficiency of the production line according to a preset fluctuation range.
[0117] S5', when a new production task appears, smoothly adjust the conveying efficiency of each production line.
[0118] Specifically, when the conveying efficiency is determined, slowly increase the transmission efficiency at a certain amplitude. After reaching the preset peak, slowly decrease the transmission efficiency at a certain amplitude, as long as the average conveying efficiency is the determined conveying efficiency.
[0119] In one embodiment, for multiple production lines, there may be a situation where production stops when the set production time is reached. In another embodiment, production continues directly at the non-zero conveying efficiency corresponding to the lowest energy consumption of the overall 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. Further, reserve warehouses are added after these processing devices with higher processing efficiency or production lines with higher conveying efficiency, and the reserve warehouses are used to store products or semi-finished products that exceed the planned tasks.
