As shown in fig. 1, the intelligent electricity-saving method of the tobacco leaf shredding production line at least comprises the following steps:
step 102, dividing the tobacco leaf shredding production line into at least two process sections based on storage spaces of all sub-processes in the tobacco leaf shredding production line.
In actual production, because the tobacco leaf shredding process line is longer, if the control unit of the production line is not reasonably divided or the equipment starting sequence and the starting time are improperly scheduled, unnecessary electric energy consumption can be generated due to overlong equipment idle running time. The cause of the unnecessary increase in power consumption is mainly as follows: 1. in the production preparation stage, part of host equipment comprises a loosening damping machine, a charging machine, a cut tobacco tunnel damping machine, a cut tobacco drier and the like, the preheating starting sequence and the preheating starting time are too early, so that the electric energy consumption is relatively high, and if the preheating starting sequence and the preheating starting time are too late, the production progress is influenced; 2. in the production stage, in order to ensure continuous operation and processing of materials, after all the devices are started, waiting for material input, because the operation of the materials on the devices always needs a certain time, although the devices are in operation, the devices at the rear stage on the production line do not pass through the materials, and at the moment, a plurality of devices on the production line are in a starting idle running state, so that unnecessary electric energy consumption is increased. 3. Equipment is not shut down in time after materials are emptied in the batch-changing production intermittent stage, and meanwhile, the next batch production is not connected in time, so that the running time of a blank car is overlong; 4. the wire production line is not subdivided into a minimum control unit, so that single starting equipment is excessive, and unnecessary electric energy consumption is increased; therefore, the power consumption in the stages of production preparation, production waiting, production gap and the like in the production process is solved, and the power consumption of the tobacco leaf shredding line can be effectively reduced.
In the embodiment of the application, the intelligent electricity-saving method of the tobacco leaf shredding production line can be applied to a production workshop of the tobacco leaf shredding production line, one or more tobacco leaf shredding production lines can be arranged in the production workshop of the tobacco leaf shredding production line, each tobacco leaf shredding production line comprises a plurality of sub-processes, wherein the plurality of sub-processes can be but are not limited to a slicing process, a metering process, a loosening and moisture regaining process, a hemp and block removing process, a laser impurity removing process, a feeding bin process, a leaf feeding process, a leaf storage process, a feeding bin process, a shredding process, a feeding bin process, a tobacco leaf drying process, a multi-stage winnowing process, a blending process, a tobacco mixing process, a flavoring process and a tobacco leaf storage process which are sequentially arranged, and each sub-process is used for processing tobacco leaves and has different capacity and cache area, so that the residence time of the tobacco leaves in each sub-process is different.
Specifically, before the tobacco leaf shredding production line operates, two sub-processes with the largest storage space can be selected as nodes according to the storage space of each sub-process, and the whole tobacco leaf shredding production line is divided into three process sections by referring to the two nodes, wherein the two sub-processes with the largest storage space can be a tobacco leaf storage process and a tobacco shred mixing process. It will be appreciated that, with reference to the above-mentioned plurality of sub-processes, the slicing process, the metering process, the loosening and conditioning process, the hemp and block removal process, the laser impurity removal process, the feeding bin process, the blade feeding process and the blade storage process may be regarded as one process section, the feeding bin process, the shredding process, the feeding bin process, the wire drying process, the multi-stage air separation process and the blending process may be regarded as one process section, and the wire mixing process, the perfuming process and the wire storage process may be regarded as one process section.

As shown in fig. 2, the tobacco leaf shredding production line may include a shredding process section, a shredding process section and a flavoring process section, wherein the shredding process section may include a slicing process, a metering process, a loosening and conditioning process, a hemp and block removing process, a laser impurity removing process, a feeding bin process, a leaf feeding process, a leaf storage process and a sheet loosening process which are sequentially arranged; the silk making process section can comprise a feeding bin process, a shredding process, a feeding bin process, a silk drying process, a multi-stage winnowing process and a blending process; the perfuming process section may comprise a yarn mixing process, a perfuming process and a yarn storage process.
It should be noted that, because the line of the tobacco leaf shredding production line is longer, if the control unit of the production line is not reasonably divided or the equipment starting sequence and the starting time are improperly scheduled, unnecessary electric energy consumption can be generated due to overlong equipment idle running time. In the embodiment of the application, each sub-process can be correspondingly provided with a control unit, so that the start and stop control of each sub-process can be realized by independently controlling each control unit. The control unit may control, but is not limited to, start, stop, power and duration of operation of the sub-process.
Reference is now made to fig. 3, which is a schematic illustration of a process segment division of a tobacco shredding line according to an embodiment of the present application. As shown in fig. 3, the leaf making process section of the tobacco leaf making production line may be provided with a control unit 1, a control unit 2, a control unit 3, a control unit 4, a control unit 5, a control unit 6, a control unit 7, a control unit 8 and a control unit 9, wherein each control unit corresponds to one sub-process in the leaf making process section; the tobacco shred processing section of the tobacco shred processing line may be provided with a control unit 10, a control unit 11, a control unit 12, a control unit 13, a control unit 14, a control unit 15, a control unit 16, a control unit 17, a control unit 18, a control unit 19, a control unit 20 and a control unit 21, each control unit corresponding to one of the sub-processes in the tobacco shred processing section; the perfuming process section of the tobacco leaf shredding production line may be provided with a control unit 22, a control unit 23 and a control unit 24, each corresponding to a sub-process in the perfuming process section.
Step 104, establishing an objective function of each process segment according to the operation parameters acquired by the control unit corresponding to each sub-process.
Specifically, after the tobacco leaf shredding production line is divided into at least two process sections, the whole tobacco leaf shredding production line starts to operate, and the total production time of each process section is calculated according to the operation time collected by the control unit corresponding to each sub-process in each process section in the operation process. It is understood that the total production time for each process segment may be, but is not limited to, reference to the following expression:
In the above-mentioned method, the step of, Corresponding to the total time of production for each process segment, n corresponds to the number of control units in each process segment,/>Corresponding to the working time of the ith control unit in each process section,/>Corresponding to the dead time of the ith control unit in each control segment.
Furthermore, the unit electricity consumption of each process section can be calculated according to the operation time and the power parameter acquired by the control unit corresponding to each sub-process in the operation process. It will be appreciated that the unit power consumption per process segment may be, but is not limited to, the following expression is referenced:
In the above formula, D corresponds to the unit power consumption of each process section, Corresponding to the total electricity consumption produced for each process segment,Corresponding to the total power consumption of each process section when the process is idleThe working power of the ith control unit corresponding to each process segment,/>No-load power corresponding to the ith control unit of each process segment,/>Corresponding to the total production per process segment.
Furthermore, the objective function of each process section can be constructed according to the calculated total production time and unit power consumption corresponding to each process section.
As an option of the embodiment of the present application, before establishing the objective function of each process segment according to the operation parameters collected by the control unit corresponding to each sub-process, the method further includes:

Judging whether foreign matters exist in the tobacco leaf shredding production line according to the first image of each process section;
when no foreign matter exists in the tobacco leaf shredding production line, each sub-process in each process section is determined to have a starting condition.
In order to accurately judge whether each control unit in the tobacco leaf shredding production line has start-stop conditions and the precision of the whole intelligent electricity-saving method, whether foreign matters exist on the production streamline of each process section can be acquired based on an industrial camera arranged above each process section before the tobacco leaf shredding production line is operated. After the first image shot by the industrial camera is obtained, but not limited to, image recognition processing may be performed on the first image, so as to analyze whether foreign objects exist on the production flow line of each process segment according to an intelligent algorithm. Possibly, when it is detected that no foreign matter is present in each process section of the tobacco shredding line, it may be determined that each control unit in each process section is provided with a start condition. It can be understood that when detecting that any at least one process section in the tobacco leaf shredding production line has foreign matters, the position of the foreign matters can be determined first, and the position of the foreign matters is sent to the terminal where the staff is located, so that the staff can process the foreign matters in time.
As a further alternative of the embodiment of the present application, after operating the tobacco shredding line in the start-up sequence of each sub-process, it further comprises:

Judging whether residual materials exist in the tobacco leaf shredding production line according to the second image of each process section;
When the fact that the residual materials are not present in the tobacco leaf shredding production line is detected, each sub-process in each process section is determined to have a shutdown condition.
In order to accurately judge whether each control unit in the tobacco leaf shredding production line has start-stop conditions and the precision of the whole intelligent electricity-saving method, whether the control unit in each process section has stop conditions can be judged according to the detected accumulated amount of materials after the tobacco leaf shredding production line is operated. When the difference value between the material accumulation amount and the preset material standard amount is detected to be in a preset first interval, the working index of the tobacco leaf shredding production line can be indicated to be finished, and whether the current tobacco leaf shredding production line still has residual materials can be judged based on a second image acquired by an industrial camera. The preset first interval may be set to 0-300kg, but is not limited thereto in the embodiment of the present application.
It will be appreciated that each control unit in each process segment may be determined to be provided with a stop condition when it is detected that there is no material remaining in each process segment in the tobacco leaf shredding line. When detecting that the residual materials exist in any process section in the tobacco leaf shredding production line, the difference value between the current material accumulation amount and the preset material standard amount can be determined in real time, and whether the residual materials exist in the current tobacco leaf shredding production line or not is judged based on the second image acquired by the industrial camera when the difference value is at the critical value of the preset first interval.
