Description

A street light control system based on the Internet of Things

technical field

The invention belongs to urban lighting systems, in particular to a street lamp control system based on the Internet of Things.

Background technique

The concept of the Internet of Things was put forward in 1999. Simply put, it is the Internet of things connected, including two meanings: First, the core and foundation of the Internet of Things is still the Internet, which is a network that extends and expands on the basis of the Internet. ;Secondly, its user terminal extends and expands to any item and between items for information exchange and communication. Based on the above introduction, the Internet of Things can be defined as: through radio frequency identification (RFID, Radio Frequency Identification), infrared sensors, global positioning systems and laser scanners and other information sensing equipment, according to the agreed protocol, all items are connected to the Internet, Information exchange and communication, so as to realize a network of intelligent identification, positioning, tracking, monitoring and management.

Street lighting in the city is a necessary and indispensable public facility in people's daily life. With the rapid development of my country's urban modernization, urban road lighting has developed rapidly in recent years, and the corresponding power consumption has also increased significantly. On the other hand, with the development of the city, there is also a part of landscape lighting in the urban public lighting. Although it can make the city more beautiful, it is an additional part of power consumption. Due to the lack of effective monitoring and management means, the current street lighting system cannot realize wired supervision technically, so there are the following problems:

1. The lamps are overloaded and the power consumption is high;

2. The life of the lamp is shortened and the maintenance cost is high;

3. The safety of the control method is low, and the energy saving effect is poor;

Contents of the invention

Aiming at the above-mentioned deficiencies, the present invention discloses a street lamp control system based on the Internet of Things, including:

An illuminance sensor, which is installed on the vehicle and is used to sense the light intensity outside the vehicle;

A satellite positioning module, which is installed on the vehicle and uses satellite positioning technology to obtain the location information of the vehicle;

The Internet of Things information receiving/sending module, which is connected with the illuminance sensor and the satellite positioning module, receives/sends the information of the illuminance sensor and the satellite positioning module;

The Internet of Things information processing module, which is connected to the Internet of Things information receiving/sending module, processes the information received from the Internet of Things information receiving/sending module and issues instructions, specifically: when the Internet of Things information processing After the module receives the vehicle positioning information and illuminance information sent by the Internet of Things information receiving/sending module, if it is judged that the vehicle position is within the range of the street lamp control system, it will receive the illuminance information sent by the vehicle through the illuminance sensor Compared with the preset brightness value preset in the Internet of Things information processing module, if it is lower than the preset brightness value, then generate a street lamp brightness adjustment instruction;

The partition control module is connected with the information processing module of the Internet of Things, and controls the street lamp according to the brightness adjustment instruction of the street lamp, so that the brightness of the street lamp reaches a preset brightness value.

The preferred solution is: the illuminance sensor, the satellite positioning module, the Internet of Things information receiving/sending module, the Internet of Things information processing module, and the partition control module communicate through GPRS or 3G network.

The preferred solution is: GPRS or 3G network adopts Zigbee wireless communication protocol to provide multiple data paths through self-organization and wireless circuit functions.

The preferred solution is: the street lamp is an LED street lamp.

The present invention utilizes the satellite positioning module and the illuminance sensor installed on the vehicle to know the geographic location and light intensity of the vehicle from time to time through the information receiving/sending module of the Internet of Things, performs data analysis and processing through the information processing module of the Internet of Things, and issues street lamp brightness adjustment instructions. It greatly saves electric energy, avoids unnecessary waste, and adopts LED street lamps, which prolongs the service life and lowers the maintenance cost.

detailed description

Below in conjunction with specific embodiment the present invention is described in further detail:

As shown in Figure 1, the present invention provides a street lamp control system based on the Internet of Things, including:

An illuminance sensor, which is installed on the vehicle and is used to sense the light intensity outside the vehicle;

A satellite positioning module, which is installed on the vehicle and uses satellite positioning technology to obtain the location information of the vehicle;

The Internet of Things information receiving/sending module, which is connected with the illuminance sensor and the satellite positioning module, receives/sends the information of the illuminance sensor and the satellite positioning module;

The Internet of Things information processing module, which is connected to the Internet of Things information receiving/sending module, processes the information received from the Internet of Things information receiving/sending module and issues instructions, specifically: when the Internet of Things information processing After the module receives the vehicle positioning information and illuminance information sent by the Internet of Things information receiving/sending module, if it is judged that the vehicle position is within the range of the street lamp control system, it will receive the illuminance information sent by the vehicle through the illuminance sensor Compared with the preset brightness value preset in the Internet of Things information processing module, if it is lower than the preset brightness value, then generate a street lamp brightness adjustment instruction;
