Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Generally, the on-off time of the equipment in the plant is determined according to the production schedule, and if no production operation is performed in a certain period of time, the equipment does not need to be turned on, so that the power is saved and the loss is reduced. For example, the pulp consumption time of the A production line is 0:26-3:12, the pulp consumption time of the B production line is 2:13-4:22, and the starting time of the pulping machine is 0:26-4: 22. Here there is a crossover in pulp time, the calculation is relatively simple, and only two periods of time require the use of refiners, which is also relatively simple to calculate. However, when there are many production lines, there are many time periods, and the calculation is troublesome, and particularly, when there are many time-crossing portions, the calculation is more complicated. For example, production lines A are respectively 0:26-1:12, 2:13-4:22, 5:12-6:23 and 7:11-7:29, production lines B are respectively 0:35-3:12, 5:12-7:00 and 7:00-7:45, and the calculation complexity is high due to the fact that a large number of operation time periods of pulping machines are used. In addition, since the given job time is not necessarily sequential, it may be, for example, 5:12 to 7:00, 0:35 to 3:12, and 7:00 to 7: 45; in this case, the computational complexity is further increased. Therefore, how to calculate the start-stop time arrangement of the shared device according to the operation time submitted by each production line is one of the technical problems to be solved in the industry at present.
In the prior art, all jobs sharing a device are generally sorted in time increments according to start time to form a series of time-ordered job time sequences. The execution times of adjacent jobs are then compared and merged.
Wherein, time combination is to combine two overlapping periods of time into one period of time, for example, 1:12-3:21 and 2:11-4:23 into 1:12-4: 23.
For another example, if the end time of the 1 st job is greater than the start time of the 2 nd job, the time of the 1 st job and the time of the 2 nd job are merged, the merged time takes the start time of the 1 st job as the start time and the end time of the 2 nd job as the end time, and then the newly formed job is continuously compared with the time of the next job. If the 1 st job's end time is less than the 2 nd job's start time, no processing is done and the 2 nd job's time is then compared to the next job's time. And repeating the steps until all the jobs are traversed and finished, and finally forming an arrangement sequence executed by the jobs, namely the start-stop time arrangement of the shared equipment. If a new added operation exists temporarily, the new operation needs to be brought into the existing operation sequence, and the new operation is recalculated and arranged once according to the steps.
In summary, the above-mentioned conventional method for calculating the running time of the shared device has the following problems:
(1) ordering according to the start time of all the jobs, the time complexity is O (nlogn) to O (n)2) And as the number of jobs increases, the time complexity of the sorting also increases significantly.
(2) Comparing and combining time periods of adjacent operations one by one, wherein the time complexity is O (n) and is higher;
(3) for the operation added in real time, the steps of comparing and sorting one by one and then comparing and combining one by one are needed to be recalculated and arranged, so that the efficiency is low.
In summary, the running time calculation method of the sharing device in the prior art has high time complexity and low calculation efficiency, thereby resulting in low control efficiency of the sharing device.
In order to solve the problem of low scheduling efficiency of start-stop time of shared equipment in the existing industrial Internet of things and reduce the complexity of logic calculation, the embodiment provides a control method of the shared equipment, time periods of shared equipment used by production lines are mapped into a time sequence of a target shift and the time sequence is encoded to convert the time sequence into an action sequence of the shared equipment, the startup and shutdown time periods of the shared equipment are directly obtained according to the action sequence, the time complexity caused by sequencing each time period one by one and comparing and combining each time period one by one is avoided, only one traversal is needed for all operations, the complexity of the running time of the shared equipment can be effectively reduced, the time complexity of the calculation is always O (1), the increase of the number of operations and the number of operations of cross operations is avoided, and the running time of the shared equipment can be conveniently and quickly obtained, thereby controlling the sharing equipment quickly and effectively.
It should be noted that the execution subject of the method may be an electronic device built inside or outside the shared device, a component in the electronic device, an integrated circuit, or a chip, and the like, and this example is not particularly limited thereto.
The control method of the sharing device of the present invention is described below with reference to fig. 1, and the method includes the steps of:
step 101, acquiring a plurality of target production lines sharing shared equipment in a target shift, and acquiring demand information of each target production line; the demand information includes a first time period for using the shared device.
The target shift is a shift required to be arranged for the running time of the sharing equipment; the current shift may be the current shift, or the future shift, which is not specifically limited in this embodiment.
The shared device is a device that can be shared by a plurality of objects and is to be subjected to runtime arrangement, such as a refiner and a pulper of a paper mill, and the like, which is not specifically limited in this embodiment.
In order to reduce the cost, the shared equipment in the factory is shared by all production lines, and as long as one production line needs to use the shared equipment, the shared equipment cannot be shut down.
The target production line is a production line sharing the same shared equipment.
The demand information includes, but is not limited to, the number of the sharing device that needs to be used and the time period that the sharing device needs to be used.
Optionally, when the running time of the shared device in the target shift needs to be scheduled and the shared device is further controlled, a plurality of target production lines sharing the shared device in the target shift may be acquired, and the requirement information of each target production line is acquired at the same time, so as to analyze and acquire the first time period for each target production line to use the shared device from the requirement information of each target production line.
The mode of acquiring the multiple target production lines may be to acquire all target production lines sharing the shared device in the target shift according to the use information of the shared device by each production line in the target shift; the requirement information of each production line in the target shift may be analyzed to obtain the number of the shared device used by each production line, match the number of the shared device used by each production line with the number of the shared device, and use the production line matched with the number of the shared device as the target production line, which is not specifically limited in this embodiment.
Step 102, dividing the target shift into a plurality of second time periods to obtain a time sequence of the target shift;
optionally, the target shift may be divided into a plurality of second time periods according to a preset number, or may be divided into a plurality of second time periods according to a preset unit time length, and the like, which is not specifically limited in this embodiment.
Then, a time series of the target shift is formed according to the plurality of second time periods.
For example, if the target shift starts from 2:00 and ends at 8:30, and the preset unit duration is 1 hour, the target shift may be divided into 7 second time segments, and the time sequence of the target shift is [2:00, 3:00, 4:00, 5:00, 6:00, 7:00, 8:00, 8:30 ].
It should be noted that each value in the time series can be characterized by a time period, such as 2:00, which is characterized by a time period of 2:00 to 3: 00.
Step 103, mapping the first time period of each target production line to the time sequence of the target shift in parallel to obtain the position information of the first time period of each target production line in the time sequence; the position information corresponding to each target production line is used for representing the starting and ending time of each target production line for using the shared equipment; optionally, after the time series of the target shift is obtained, the first time period of each target production line may be mapped to the time series of the target shift in parallel, and the position information of the position occupied by the first time period of the shared device used by each target production line in the time series of the target shift is determined.
The position information includes one or more combinations of numbers, time and duration of the starting position and the ending position.
The position information is used for representing the starting and ending time of the target production line needing to use the shared equipment in the time sequence.
In the embodiment, the first time periods of the target production lines are directly mapped to the time sequence of the target shift in parallel, so that the time complexity caused by one-to-one comparison and sequencing of each first time period is avoided, and the time complexity and the logic complexity of the running time calculation of the shared equipment can be effectively reduced.
And 104, coding the time sequence according to the position information, and controlling the sharing equipment according to a coding result.
The position information is used for representing which time in the time sequence needs to use the shared device, namely representing the action state of the shared device in each time; the action state includes power on or power off. It should be noted that the encoding result in the following is an action sequence of the sharing device, and the action sequence includes a plurality of encoding values.
Optionally, after the position information of the first time period of each target production line in the time sequence is obtained, it may be determined whether a target production line needs to use the shared device in each second time period of the time sequence according to the position information. Therefore, the time sequence can be directly encoded according to the position information, and the second time period when the target production line needs to use the shared device and the second time period when the non-target production line needs to use the shared device are differentially encoded, so that the time sequence is converted into the action sequence of the shared device.
The encoding method may be a character string, a numerical value, or the like, and this embodiment does not specifically limit this.
For example, if the time series is encoded with 1 and 0, and 1 and 0 are used to represent the power-on and power-off actions of the sharing device, respectively, the action sequence of the sharing device in the target shift mapped by the time series of the target shift can be characterized as:
in the initial state, the initial action sequence is [0,0,0, … … 0], i.e. the entire shift is in the shutdown state; when the target production line needs to use the shared device in the period from T0+ T to T0+3T, the shared device needs to be powered on at a time point of T0+ T until the shared device is powered off at a time point of T0+3T, and the code values in the action sequence of the target shift are updated to [0,1,1,0, 0, … … 0 ].
Then, the action state of the sharing equipment in each second time period can be obtained in real time according to the coding result, and the sharing equipment is controlled quickly and accurately at the corresponding time point.
In the embodiment, the time sequence is directly encoded according to the position information, and can be converted into the action sequence of the shared device, so that the running time arrangement result of the shared device is directly obtained, the time complexity caused by one-to-one comparison and combination of each first time period is avoided, the time complexity and the logic complexity of running time calculation of the shared device can be effectively reduced, the consumption of calculation resources is reduced, the calculation efficiency is improved, the control process of the shared device is simplified, and the control efficiency is improved.
It should be noted that, for the operation time newly inserted during the operation or during the update process of the action sequence, the action sequence is updated once in time in the same manner, and it is not necessary to reorder, compare and merge the time periods when all the production lines use the shared device, so that the computation complexity and time complexity are effectively reduced, and the computation efficiency is effectively improved.
In the embodiment, the first time period of each target production line is directly mapped to the time sequence of the target shift in parallel to obtain the position information of the first time period of each target production line in the time sequence, and the time sequence is encoded according to the position information so as to directly convert the time sequence into the action sequence of the shared equipment, thereby quickly and accurately controlling the shared equipment; the total time complexity caused by one-to-one comparison and sequencing of each first time period and the total time complexity caused by one-to-one comparison and combination of each first time period are greatly reduced, the calculation efficiency is improved, the resource consumption is reduced, the logic complexity of the running time calculation of the sharing equipment is reduced, the control process of the sharing equipment is effectively simplified, and the sharing equipment is conveniently and quickly controlled.
On the basis of the foregoing embodiment, in this embodiment, the dividing the target shift into a plurality of second time periods to obtain a time sequence of the target shift includes: acquiring the starting time and the ending time of the target shift; acquiring the total duration of the target shift according to the starting time and the ending time; dividing the total time length of the target shift by the preset unit time length and rounding upwards to obtain the total time segment number of the target shift; and dividing the target shift into a plurality of second time periods according to the total time period number to obtain a time sequence of the target shift.
The preset unit duration is duration of basic operation or unit operation of one device, such as 5 seconds, 10 minutes, 1.3 hours and the like, and the unit durations of different operations of different devices are different and can be specifically set according to actual requirements.
Optionally, the specific step of obtaining the time series of the target shift includes:
first, the start time T0 and the end time Td of the target shift are acquired.
Then, the time difference between the ending time Td and the time before the starting time T0 of the target shift is calculated to obtain the total duration T of the target shift.
Then, in order to ensure accurate division of the target shift, dividing the total time length T of the target shift by a preset unit time length T and rounding up to obtain the total time segment number N of the target shift, wherein the specific calculation formula is as follows:
N=⌈T/t⌉；
where N is the total number of time segments of the target shift, t is a preset unit duration, and ⌈ ⌉ represents a rounding-up operation.
Then, dividing the target shift into a plurality of second time periods according to the total time period number to obtain a time sequence of the target shift; the number of the second time periods is determined according to the total time period number, namely the total time period number is directly used as the number of the second time periods under the condition that the result of dividing the total time length by the preset unit time length is 0; and under the condition that the division result of the total time length and the preset unit time length is not 0, adding 1 to the total time section number to be used as the number of the second time section.
For example, in a case where the total duration of the target shift is T, the starting time is T0, the preset unit duration is T, and there is a margin in the division result between the total duration and the preset unit duration, the target shift is divided into a time series with a series length of N +1, specifically denoted as [ T0, T0+ T, T0+2T, … …, T0+ (N-1) T, T0+ T ], and the corresponding position subscripts are [0 th, 1 st, 2 nd, 3 rd, … … nth ].
For another example, if the target shift starts from 2:00 and ends at 8:30, the total time duration is 6.5 hours, and the preset unit time duration is 1 hour, the time series length of the target shift is 7, which is specifically expressed as follows: [2:00,3:00,4:00,5:00,6:00,7:00,8:00,8:30].
It should be noted that, in order to ensure the accuracy of the time series, the last bit of the time series is the end time of the target shift, i.e., T0+ T, instead of T0+ Nt, so that the start time and the end time of the time series are consistent with the target shift, i.e., the end of the target shift is indicated at T0+ T, and the start of the target shift is indicated at T0.
