Large intelligent light energy-saving control method based on wireless sensor actuator network

Abstract

The invention provides a large intelligent light energy-saving control method based on a wireless sensor actuator network. The method comprises the following steps that 1, the filter parameters of sensor nodes are initialized; 2, a sensor is started, and a monitored area is detected; 3, fusion is carried out on different measurement information; 4, the gain of a filter is calculated, and the predicted value of the filter is updated; 5, corresponding operations are executed according to the predicted value of the current filter. A distributed cooperation estimation and control algorithm is adopted, each node can synergistically estimate the states of a vehicle according to the measurement information of each node by receiving the measurement information of the adjacent nodes, and a controller controls commands according to the states. Due to the fact that the vehicle is monitored in real time and light is controlled in real time, compared with a traditional illumination system, the method greatly reduces energy consumption, sector areas needing to be lightened are estimated according to Kalman forecast, the luminance of the light is controlled, energy is saved, and user-friendly comfort is achieved.

Description

technical field

[0001] The invention relates to an intelligent lighting control technology of a wireless sensor actuator network, in particular to a large-scale intelligent lighting energy-saving control method based on a wireless sensor actuator network. Background technique

[0002] Large-scale underground garages usually have no natural light, use artificial lighting, install a large number of lamps, consume a lot of power resources, especially when there are no or only a small number of vehicles entering and exiting, a large number of lights are lit, resulting in waste of resources. In order to achieve the purpose of energy saving and emission reduction, it is necessary to develop an intelligent lighting control system, which can reasonably schedule the lights according to the actual situation to reduce energy consumption. The wireless sensor actuator network has the characteristics of low power consumption, low cost, distribution and self-organization, which can effecti...
