All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
First embodiment
FIG. 1 is a flow chart of a method for implementing formula calculation provided in an embodiment of the present invention.
As shown in FIG. 1, the implementation method of the formula calculation includes steps S110-S150:
s110, acquiring initial time;
s120, obtaining the calculation periods of all calculation formulas;
s130, grouping the calculation formulas according to the calculation periods corresponding to the calculation formulas;
s140, setting a timing task, and acquiring an execution period of the timing task according to a calculation period;
and S150, determining the execution step of the calculation formula according to the real-time and the initial time.
The embodiment of the invention provides a method for realizing formula calculation, which comprises the steps of firstly, acquiring initial time corresponding to program starting; secondly, obtaining the calculation periods of all calculation formulas; grouping the calculation formulas again according to the calculation periods corresponding to the calculation formulas; then setting a timing task, and acquiring an execution period of the timing task according to a calculation period, wherein the timing task comprises real-time acquisition; and finally, determining an execution step of the calculation formula according to the real-time and the initial time, wherein the execution step comprises the step that the calculation formula carries out calculation or the calculation formula waits for the next timing task. Aiming at the scene that the calculation formula is continuously calculated, the timing task is set, the execution period of the timing task is calculated according to the calculation period of the calculation formula, and then the execution period obtains the real-time corresponding to the execution period, so that the calculation formula adopts a reasonable calculation period in the calculation process, and the problems of waste of calculation resources, substandard calculation frequency and the like caused by unreasonable setting of the calculation period in the formula calculation process in the prior art are solved.
Specifically, in step S110, the initial time is the time corresponding to the program start, that is, the system time when the software corresponding to the implementation method of formula calculation starts to run in the present invention, and can be directly obtained. In particular, in the present embodiment, the initial time is a time corresponding specifically to seconds, for example, 12/30/11/32/21 in 2020.
Specifically, in step S130, grouping the calculation formulas according to the calculation periods corresponding to the calculation formulas includes:
judging whether the calculation periods of different calculation formulas are the same or not;
if yes, the calculation formulas corresponding to the same calculation period are divided into a group.
Specifically, different calculation formulas may correspond to different calculation periods according to actual data requirements, and different calculation formulas may also correspond to different calculation periods according to actual data requirements, where the calculation periods may be 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, 100 seconds, and the like. The calculation periods of the different calculation formulas can be obtained according to actual data requirements. Then judging whether the calculation periods of different calculation formulas are the same or not; if so, dividing the calculation formulas corresponding to the same calculation period into a group, so that the calculation periods of the calculation formulas in each group are the same.
Specifically, after the calculation formula grouping is completed, a timing task needs to be set, and the execution period of the timing task is determined according to the grouping condition. In particular, the timing task is to obtain real time, which is also time specifically corresponding to seconds, such as 12 months and 30 days in 2020, 11:32: 28. The timing task is executed once per execution cycle, namely real-time is acquired once per execution cycle, and the execution cycle is fixed time. Referring to fig. 2, fig. 2 is a flowchart of an implementation method for obtaining an execution cycle according to an embodiment of the present invention.
As shown in fig. 2, obtaining the execution cycle may specifically include the following steps S210 to S230:
s210, acquiring calculation cycles of different grouping calculation formulas;
s220, calculating the greatest common divisor of the calculation periods of all the grouping calculation formulas;
and S230, determining the greatest common divisor as the execution period of the timing task.
Specifically, in step S220, the greatest common divisor of the calculation periods of all the grouping calculation formulas is calculated, if an integer is a divisor of several integers at the same time, the integer is called as their common divisor; the largest of the common divisor is called the greatest common divisor; for any number of positive integers, 1 is the greatest common divisor. For example, the calculation formulas are divided into 3 groups of 5 seconds, 10 seconds and 15 seconds according to the calculation period, where 5 seconds is the greatest common divisor of the calculation periods of all the grouped calculation formulas, and 5 seconds is the execution period of the timing task. For example, the calculation formulas are divided into 4 groups of a calculation period of 2 seconds, a calculation period of 3 seconds, a calculation period of 4 seconds and a calculation period of 20 seconds according to the calculation periods, where 1 second is the greatest common divisor of the calculation periods of all the grouped calculation formulas, and then 1 second is the execution period of the timing task.
Specifically, after obtaining the execution period of the timing task, the execution step of the calculation formula may be determined according to the timing task and the execution period thereof. Referring to fig. 3, fig. 3 is a flowchart of an implementation of determining an execution step of a calculation formula according to real time and initial time according to an embodiment of the present invention.
As shown in fig. 3, the step of determining the execution of the calculation formula according to the real-time and the initial time may specifically include the following steps S310 to S350:
s310, calculating a difference value between the real-time and the initial time;
s320, respectively calculating remainders obtained by dividing the difference values by different grouping calculation periods;
s330, respectively comparing the remainder of different grouping calculation periods with the size of the timing operation execution period;
s340, if the remainder is less than the execution period of the timing operation, calculating a calculation formula corresponding to the grouping calculation period;
and S350, if the remainder is larger than the execution period of the timing operation, waiting for the next timing task by the calculation formula corresponding to the grouping calculation period.
Specifically, in step S310, in the step of calculating the difference between the real-time and the initial time, if the initial time is 11:32:21 and the real-time is 11:32:26, the difference between the real-time and the initial time is 5 seconds. If the calculation period of one packet is 4 seconds, the remainder of the calculation of the difference divided by the calculation period of this packet is 1 second. Determining the execution period of the timing task according to the steps S210-S230, wherein if the execution period obtained through the steps S210-S230 is 2 seconds, the remainder is 1 second and is smaller than the execution period, and the calculation step is executed by the calculation formula corresponding to the packet corresponding to the remainder being 1 second; if the remainder obtained in step S310-S320 is 3, the remainder is 2 seconds longer than the execution period, and the calculation formula corresponding to the packet with the remainder of 3 seconds waits for the next timing task.
Specifically, aiming at a scene that a calculation formula is continuously calculated, a timing task is set, an execution period of the timing task is calculated according to the calculation period of the calculation formula, then real-time corresponding to the execution period is obtained, and a difference value between the real-time and initial time is calculated; respectively calculating the remainder after dividing the difference value by different grouping calculation periods; respectively comparing the remainder of different grouping calculation periods with the size of the timing operation execution period; if the remainder is less than the execution period of the timing operation, calculating a calculation formula corresponding to the grouping calculation period; if the remainder is larger than the timing operation execution period, waiting for the next timing task by the calculation formula corresponding to the grouping calculation period; therefore, the reasonable calculation period is adopted in the calculation process of the calculation formula, the problems of the prior art that the calculation resource is wasted and the calculation frequency does not reach the standard due to the unreasonable setting of the calculation period in the formula calculation process are solved, the calculation efficiency is improved, and the waste of the calculation resource is reduced.
Specifically, the calculation formula corresponding to the grouping calculation period is calculated, and the configuration of multiple formulas is also required to be completed. Please refer to fig. 4 for a specific implementation method of the configuration calculation formula, and fig. 4 is a flowchart of implementing the configuration calculation formula provided in an embodiment of the present invention.
As shown in fig. 4, configuring the calculation formula may specifically include the following steps S410 to S420:
s410, configuring a calculation formula corresponding to the grouping calculation period;
and S420, setting data needing to be acquired in the calculation formula as variables.
Specifically, in step S410, the calculation formula corresponding to the grouping calculation period is configured, including the operation sign and the operation relation of the calculation formula. In step S420, after the data required to be obtained in the calculation formula is set as a variable, the data required by the calculation formula in the intelligent device is also required to be obtained, so as to obtain first data; and then uploading the first data to a configured calculation formula, and calculating. The data required by the calculation formula in the intelligent equipment is acquired, and the data of the intelligent equipment can be acquired through the sensor.
Specifically, uploading the first data to a calculation formula after configuration is completed, and performing calculation, specifically including:
uploading the first data to a configured calculation formula;
replacing the variable with first data;
and resolving the calculation formula into a tree structure, and calculating.
In the embodiment, the calculation formula is configured in advance and the variables are set, and then the calculation formula is analyzed into the tree structure for calculation, so that the problem that the actual requirement of formula calculation cannot be realized due to the lack of the support formula in the prior art is solved; the formula supported by the invention realizes the calculation of various efficiencies and indexes of the equipment, the calculation of binary data such as bit operation, bit value and the like and the calculation of some logic judgment assignment formulas.
