Problems solved by technology

However, because pedestrian road lights generally use ordinary lighting equipment, compared with high-power street lights for motor vehicle lanes, they have low power consumption and high reliability. Therefore, they have not received much attention in terms of energy-saving control and intelligence.

Embodiment 1

[0029] 1. Working method of straight sidewalk

[0030] Such as image 3 As shown, the street lamps a, b, c, d, e are arranged sequentially along the straight sidewalk 2, the energy-saving controller 1 is installed on the street lamps b and d respectively, and the human body microwave radar sensor can detect the range 3-1 and 3-2 (circular dashed box). When a pedestrian 4 walks into the detectable range 3-1 of the human body microwave radar sensor on the street lamp b, the microprocessor drives the relays of the street lamps a, b, and c, so that the street lamps a, b, and c are powered on, and then illuminate the pedestrians passing by The area illuminated by street lights a, b, c. At the same time, the microprocessor sends a wake-up signal through the Zigbee module to start the energy-saving controller 1 installed on the sidewalk light d. Such as Figure 4 As shown, when a pedestrian 4 walks into the detection range 3-2 of the human body microwave radar sensor on the stree...

Embodiment 2

[0041] 1. Working method of straight sidewalk

[0042] Such as Figure 9 As shown, the street lamps a, b, c, d, e, f, g are arranged sequentially along the straight sidewalk 2, the energy-saving controller 1 is installed on the street lamps b and e respectively, and the detectable range of the human body microwave radar sensor is expressed as 3-1 and 3-2. When the pedestrian 4 walks into the detectable range 3-1 of the human body microwave radar sensor on the street lamp b, the microprocessor drives the relays of the pedestrian road lamps a, b, and c, so that the street lamp is powered on. At the same time, the microprocessor sends a wake-up signal through the Zigbee module to start the energy-saving controller 1 installed on the sidewalk light e.

[0043] Such as Figure 10 As shown, when the pedestrian 4 enters the detectable range 3-2 of the human body microwave radar sensor on the street lamp e, the microprocessor drives the relays of the pedestrian road lamps d, e, f, ...

Abstract

The invention provides an Internet-of-things-technology-based sidewalk streetlamp energy-saving controller, which comprises a microprocessor. The microprocessor is connected with a light intensity sensor, a human microwave radar sensor and a Zigbee module. The output of the microprocessor is connected with a relay. Contacts of the relay are positioned on a power line of a streetlamp. When the light intensity sensor detects that light rays of an ambient environment are reduced to a set lower limit, the microprocessor awakens the human microwave radar sensor; after the human microwave radar sensor senses a pedestrian for longer than first set time, the microprocessor of the energy-saving controller drives the relay of the streetlamp within a detection range to power the streetlamp on; and when the pedestrian walks away from the detection range of the human microwave radar sensor for longer than second set time, the microprocessor drives the relay of the streetlamp within the detection range to turn the streetlamp off. The controller has the advantages that: intelligent control, environment friendliness and energy saving are realized actually without manual intervention; and the controller has a simple and reliable structure and low cost, and is easy to implement.

Description

technical field [0001] The invention relates to an energy-saving controller, in particular to an energy-saving controller for sidewalk lights based on Internet of Things technology. Background technique [0002] "Advocating energy saving and emission reduction, creating a green life" is currently advocating a way of life, and energy shortage has become the focus of attention in the world. [0003] As a part of urban infrastructure, street lamps play an irreplaceable role in urban road lighting. At present, there are special street lights on the sidewalks in many cities, but the control and management of these street lights still adopt the traditional method, and all of them should be turned on on the road sections with few pedestrians, which wastes energy in vain. [0004] With the rapid development of science and technology, the maturity of sensor, network transmission, global positioning and other technologies has promoted the application of "Internet of Things" in daily ...
