Step S106, determining whether the capacitor to be identified is the capacitor in the target network or not based on the initial voltage and the current voltage.
In the embodiment of the invention, the initial voltage of a target network in a capacitive internet of things system is detected, wherein the target network is any one wireless network in the capacitive internet of things system; accessing a capacitor to be identified into a target network, and detecting the current voltage of the target network; whether the capacitor to be identified is the capacitor in the target network or not is determined based on the initial voltage and the current voltage, the purpose that the position of the capacitor in the Internet of things can be determined is achieved, and the technical problem that the access position of the capacitor in the Internet of things system is difficult to determine in the prior art is solved, so that the technical effect of rapidly judging the network connection state of the capacitor is achieved.
The above method is explained in detail below.
Assume that a capacitive internet of things system exists simultaneously with a plurality of wireless networks, including: a plurality of wireless networks such as ABCD now need to determine a network connection state of a certain capacitor X (i.e., a capacitor to be identified).
Before the capacitor X is switched in, the voltage (namely, initial voltage) of the current power grid corresponding to the A network is collected.
After the acquisition is completed, the capacitor X is put into the system in a certain short period.
The voltage of the grid (i.e., the present voltage) is then collected again.
And judging the change of the voltage acquired twice, if the amplitude of the change is within a certain threshold range, judging that the capacitor X is on the network A, otherwise, judging that the capacitor X is not on the network A.
In the embodiment of the present invention, as shown in fig. 2, step S106 includes the following steps:
in step S1061, if a difference between the initial voltage and the current voltage is smaller than a preset threshold, the capacitor to be identified is a capacitor in the target network.
Step S1062, if the difference between the initial voltage and the current voltage is greater than or equal to the preset threshold, the capacitor to be identified is not a capacitor in the target network.
In the embodiment of the present invention, by solving the difference between the initial voltage and the current voltage, and determining the relationship between the difference and the preset threshold, in the case that the difference is smaller than the preset threshold, the capacitor to be identified at is the capacitor in the target network.
And under the condition that the difference value is larger than or equal to the preset threshold value, determining that the capacitor to be identified is not the capacitor in the target network.
It should be noted that the preset threshold may be set by a worker according to an actual situation, and is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, as shown in fig. 3, the method further includes the following steps:
and S108, if the capacitor to be identified is not the capacitor in the target network, accessing the capacitor to be identified to other networks, wherein the other networks are wireless networks except the target network in the capacitive Internet of things system.
In the embodiment of the invention, if the capacitor to be identified is not the capacitor in the target network, the capacitor to be identified is connected to other networks in the content networking system, and the steps S102 to S106 are executed again until the network where the capacitor to be identified is located is determined.
In the capacitance Internet of things system, the network connection state of the capacitor can be judged quickly by detecting the voltage change in a short time when the capacitor is put into a power grid, so that the networking state of the capacitor can be adjusted quickly and conveniently in the follow-up process.
