All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention. The technical means used in the examples are conventional means well known to those skilled in the art unless otherwise indicated.
In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
First embodiment
FIG. 1 is a flow chart of a method for implementing formula computation provided in one embodiment of the invention.
As shown in fig. 1, the implementation method of the formula calculation includes steps S110 to S150:
s110, acquiring initial time;
s120, acquiring 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 the calculation period;
s150, determining an execution step of a 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 obtaining initial time corresponding to program starting; secondly, acquiring calculation periods of all calculation formulas; grouping the calculation formulas according to the calculation periods corresponding to the calculation formulas; setting a timing task, and acquiring an execution period of the timing task according to the calculation period, wherein the timing task comprises acquiring real-time; 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 calculation of the calculation formula or the waiting of the calculation formula for the next timing task. Aiming at the scene that the calculation formula is continuous calculation, 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 calculation period setting in the calculation process of the formula in the prior art are solved.
Specifically, in step S110, the initial time is the time corresponding to the starting time of the program, that is, the system time corresponding to the starting time of the software for implementing the formula calculation in the present invention, may be directly obtained. In particular, in the present embodiment, the initial time is a time specifically corresponding to seconds, for example, 11:32:21 on 12 months and 30 days in 2020.
Specifically, in step S130, the calculation formulas are grouped according to the calculation period corresponding to the calculation formulas, which specifically 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 can correspond to different calculation periods according to actual data requirements, different calculation formulas can also correspond to different calculation periods according to actual data requirements, and the calculation periods can be 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, 100 seconds and the like. The calculation period of different calculation formulas can be obtained according to the actual data requirement. Then 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, so that the calculation periods of the calculation formulas in each group are the same.
Specifically, after the calculation formula is grouped, 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 acquire a real-time, which is also a time specifically corresponding to seconds, for example, 11:32:28 on 30 th month of 2020. The timing task is executed once every execution period, that is, the real-time is acquired once every execution period, and the execution period is a fixed time. Referring to fig. 2, fig. 2 is a flowchart illustrating a method for obtaining an execution cycle according to an embodiment of the present invention.
As shown in fig. 2, the execution cycle is obtained, which may specifically include the following steps S210 to S230:
s210, acquiring calculation periods 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 group calculation formulas is calculated, and if an integer is a divisor of several integers at the same time, the integer is called as their common divisor; the greatest of the common divisors is called the greatest common divisor; for any number of positive integers, 1 is the greatest common divisor. For example, if the calculation formulas are divided into 3 groups each having a calculation period of 5 seconds, a calculation period of 10 seconds, and a calculation period of 15 seconds according to the calculation period, the greatest common divisor of the calculation periods of all the group calculation formulas is 5 seconds, and the execution period of the timing task is 5 seconds. For example, if the calculation formulas are divided into 4 groups of 2 seconds, 3 seconds, 4 seconds and 20 seconds according to the calculation period, 1 second is the greatest common divisor of the calculation periods of all the group calculation formulas, and 1 second is the execution period of the timing task.
Specifically, after the execution period of the timing task is obtained, 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 a method for determining an execution step of a calculation formula according to a real-time and an initial time, which is provided in an embodiment of the present invention.
As shown in fig. 3, the determining the execution step 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 remainder after dividing the difference value 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 smaller than the timing operation execution period, calculating a calculation formula corresponding to the grouping calculation period;
s350, if the remainder is greater than the timing job execution period, the calculation formula corresponding to the grouping calculation period waits for the next timing task.
Specifically, in step S310, the difference between the real-time and the initial time is calculated, and 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 difference divided by the calculation period of this packet is 1 second. According to the steps S210-S230, the execution period of the timing task can be determined, if the execution period obtained in the steps S210-S230 is 2 seconds, the remainder is 1 second less than the execution period, and the calculation step is executed according to the calculation formula corresponding to the packet corresponding to the remainder 1 second; if the remainder obtained in the other group through steps S310-S320 is 3, the remainder is 2 seconds greater than the execution period, and the calculation formula corresponding to the packet corresponding to 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, the execution period of the timing task is calculated according to the calculation period of the calculation formula, then the real-time corresponding to the execution period is obtained, and the difference value between the real-time and the initial time is calculated; respectively calculating remainder after dividing the difference value by different grouping calculation periods; comparing the remainder of the different grouping calculation periods with the size of the timing operation execution period respectively; if the remainder is smaller than the timing operation execution period, calculating a calculation formula corresponding to the grouping calculation period; if the remainder is greater than the timing job execution period, waiting for the next timing task by a calculation formula corresponding to the grouping calculation period; therefore, a reasonable calculation period is adopted in the calculation process of the calculation formula, the problems of waste of calculation resources, substandard calculation frequency and the like caused by unreasonable calculation period setting in the calculation process of the formula in the prior art are solved, the calculation efficiency is improved, and the waste of calculation resources is reduced.
Specifically, the calculation formulas corresponding to the grouping calculation periods are calculated, and the configuration of multiple formulas is required to be completed. Referring to fig. 4, fig. 4 is a flowchart illustrating a configuration calculation formula according to an embodiment of the present invention.
As shown in fig. 4, the configuration calculation formula may specifically include the following steps S410 to S420:
s410, configuring a calculation formula corresponding to the grouping calculation period;
s420, setting data to be acquired in a calculation formula as variables.
Specifically, in step S410, a calculation formula corresponding to the grouping calculation period is configured, including an operation symbol and an operation relation of the configuration calculation formula. In step S420, after setting the data required to be acquired in the calculation formula as a variable, the data required by the calculation formula in the intelligent device is also required to be acquired, so as to obtain first data; and uploading the first data to a calculation formula after configuration is completed, 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 calculating the calculation formula, specifically including:
uploading the first data to a calculation formula after configuration is completed;
replacing the variable with first data;
and analyzing the calculation formula into a tree structure and calculating.
