Problems solved by technology

Some methods use sensors to obtain device status information, however, this method requires the installation of a large number of sensors to monitor the status of all devices
[0014] The above-mentioned sensor deployment scheme using genetic algorithm has high complexity and low efficiency, and may have the following problems: the similarity of devices under the same sensor is high, which affects the result of device status detection

[0062] Such as Figure 4 As shown, the specific process is as follows:

[0063] Step 1: Generate at least one grouping result of energy consuming equipment, and use the generated grouping result as the current grouping result;

[0064] Specifically, first, set the total number M of grouping results and the maximum number T of derived generations. Define the length L=N of the bit string. Energy consuming devices are randomly divided into Ci groups, Ci∈[1,N], i∈M. In this step, M ...

Abstract

The invention discloses a method and device for deploying sensors, and relates to the field of energy audit. According to the scheme, the sensors are deployed by grouping energy consumption equipment. According to the method, the energy consumption equipment is pre-grouped to obtain a grouping result, a fitness value corresponding to the grouping result is confirmed according to the entropy of each group in the grouping result, and adjustment is carried out on the grouping result according to the fitness value, wherein the entropy stands for the energy consumption difference of the energy consumption equipment contained in the corresponding groups. Therefore, the scheme of deploying the sensors by grouping the energy consumption equipment is achieved.

Description

technical field [0001] The invention relates to the field of energy auditing, in particular to a sensor deployment method and device. Background technique [0002] Energy saving is an issue that has attracted much attention in recent years. There are broadly two ways to save energy, one is to produce more energy-efficient equipment, and the other is to reduce energy usage through the continuous participation of equipment owners. According to literature records, since the cost of the latter method is much less than that of the former method, the latter method is more feasible and easier to accept. [0003] Studies have shown that if users can directly obtain energy information, it will help energy conservation. However, most people cannot effectively control the energy consumption of equipment due to the lack of energy information. [0004] There are currently several ways to help users obtain energy information. One of them is to set up an automated control system to rea...
