Abstract

The invention relates to a method for triggering randomization of a timing task of Internet of things equipment, which comprises a period value T, a constant K and an interval constant P of the timing task, and comprises the following steps: obtaining a serial number SN of electronic equipment in the Internet of things, converting the serial number SN into a corresponding integer value I according to a unified method, dividing the integer value I by a constant K, then taking a remainder, multiplying the remainder by an interval constant P to obtain a product, and finally adding the product and a random value X between 0 and P-1 to obtain a sum, wherein the sum is a trigger time point t of a timing task; and triggering a timing task when a time point t is reached through the timing of a timer. The method can disperse the timing tasks to the time points from 0 to T according to the periodic value T of the timing tasks, and reduces the concurrent number of the timing tasks of the electronic equipment, thereby greatly reducing the load pressure of a control platform at a certain time point and expanding the overall number of control equipment of the control platform.

Trigger method for timing task randomization of Internet of things equipment

Technical Field

The invention relates to the field of Internet of things equipment, in particular to a method for randomly triggering a timing task of Internet of things equipment for online monitoring of the state of the equipment in a network.

Background

With the continuous popularization of electronic devices in the internet of things, the number of devices managed by a device control platform is increasing, and devices often have a requirement for reporting the state of the devices at regular time.

Disclosure of Invention

In order to solve the problems, the invention provides the method for randomly triggering the timing task of the internet of things equipment, which can automatically and randomly distribute the timing task triggering time of each piece of electronic equipment according to the requirement.

In order to achieve the purpose, the method for triggering the randomization of the timing task of the internet of things equipment comprises the steps of obtaining a sequence number SN of electronic equipment in the internet of things by a period value T, a constant K and an interval constant P of the timing task, converting the sequence number SN into a corresponding integer value I according to a unified method, dividing the integer value I by the constant K, taking a remainder, multiplying the remainder by the interval constant P to obtain a product, and adding the product and a random value X between 0 and P-1 to obtain a sum, wherein the sum is a triggering time point T of the timing task; and triggering a timing task when a time point t is reached through the timing of a timer.

In a further aspect, the period value T = a constant K × an interval constant P.

Compared with the prior art, the method for triggering the randomization of the timing task of the internet of things equipment can disperse the timing task to the time points from 0 to T according to the period value T of the timing task, and the larger the value T is, the more the distribution points of the time points are. The time point t obtained by calculation is fixed for each electronic device, and is randomly distributed to different time points, so that the concurrency number of timing tasks of the electronic devices is reduced, the load pressure of a control platform at a certain time point is greatly reduced, and the whole number of control devices of the control platform is enlarged. Furthermore, the relation between the period value T and the constant K and the interval constant P is determined, and the relation between the constant K and the constant P can be set according to needs, so that the value of the obtained time point T is further controlled according to needs, and the starting time point is controlled according to the load condition of the control platform.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below.

Example 1.

The method for triggering the randomization of the timing task of the internet of things device described in this embodiment includes the following steps:

s110: determining the timing task period value to be 24 hours, namely the period value T =86400 seconds; if the interval constant P =30, the constant K =86400/30=2880 is set.

S120: the electronic device serial number SN =123456789 is obtained.

S130: the device serial number is converted to an integer value.

The device serial number in this embodiment may have various numbering modes due to different numbering methods of different device manufacturers. One way always can be found to convert the serial number to an integer value. The present invention does not specifically limit the specific manner of converting the device serial number into the integer value, and it is considered that the present invention can accept a method of converting different device serial numbers into different integer values.

The device serial number SN =123456789 is a character string, and six-bit characters are taken from the character string and converted into an integer value I = 456789.

S140: the remainder is obtained by dividing the integer value I by a constant K associated with the period value T, which is 456789/2880, and the remainder is 1479.

S150: the remainder is multiplied by the interval constant P, i.e. 1497 × 30= 44910.

S160: finally, adding a random value X between 0 and P-1 to the obtained product to obtain a time t between 44910 and 44939, wherein the time t is expressed in seconds and is converted into 12: 28: 30 and 12: 28: 59, at a point in time.
