Intelligent streetlight control system and method based on satellite positioning and cooperation

Abstract

The invention discloses an intelligent streetlight control system and method based on satellite positioning and cooperation, relates to the field of smart cities, and solves the problem that traditional streetlights cannot light in real time as required. The streetlight control system is composed of a terminal device installed in a vehicle or carried by a pedestrian, a control device installed at streetlight nodes and an intelligent streetlight cooperative control network composed of streetlight nodes. The terminal device obtain its own positional information, including latitude and longitude, direction and speed, by using a satellite positioning module, and the positional information is processed and then is transmitted to a neighboring streetlight node via a wireless link. The streetlight node receives a positional information table sent by the terminal device, shares the information with related streetlight nodes according to an electronic map, and controls the on-off states of the streetlights in accordance with an established strategy. The intelligent streetlight control system is not subject to interference of other objects, is not restricted by terrain, is precise in control, solves accurate lighting and real-time lighting, achieves on-demand intelligent lighting and carry-on streetlights, and is high in energy efficiency.

Description

technical field [0001] The invention relates to an intelligent street lamp control device and control method based on satellite positioning and coordination in the field of smart cities. It is suitable for "on-demand lighting" street lamp control on urban roads and communities. Terrain restrictions, high accuracy, high energy saving rate. Background technique [0002] Traditional street lighting has the problem that it cannot be flexibly controlled. In the middle of the night, if the street lights are always on, it will cause a large waste of electric energy and light pollution; if the street lights are turned off, it will cause inconvenience to people traveling at night. At present, there are already some control methods for street lighting. These methods use technologies such as sensors to detect vehicles and pedestrians, reduce the illuminance of street lights or turn off street lights, so as to achieve the effect of energy saving. However, the sensor is easily disturbed...

AI Technical Summary

Problems solved by technology

However, the sensor is easily disturbed by external objects, and the effect is not good

Street lighting control methods mainly include: 1. Vibration detection device, which is low in cost, but is easily disturbed by other external factors, such as animals, etc. It has higher requirements on the sensitivity limit value of the outside world, and is generally not used alone

2. Infrared detection device, the power consumption of the device is small, the concealment is good, the price is low, it is very suitable at night, but it is easily interfered by various heat sources

Infrared penetration is poor. Due to the increase of trees and buildings in the community, the infrared radiation of the human body is easily blocked and is not easily received by the detector.

3. Doppler radar device is expensive and requires a specific angle to complete accurate measurements
