Street lamp system based on PLC gradient dimming and machine vision

Abstract

The invention provides a street lamp system based on PLC gradient dimming and machine vision. The system is characterized by comprising a monitoring camera, a PC, an output card, a PLC device and a street lamp set, wherein the street lamp set is composed of multiple street lamp pairs, each street lamp pair is composed of two street lamps which are oppositely arranged at two sides of a road, the monitoring camera is a traffic monitoring camera arranged on the road, the output card is a multi-path analog output card, can output a voltage signal and is provided with multiple output ports, one endof the PC is connected with the monitoring camera, the other end is connected with input ports of the output card, the multiple output ports of the output card are connected with the PLC device, andthe PLC device is used for controlling each street lamp pair in the street lamp set. The system is advantaged in that the system can be started in the middle night, brightness of the street lamps is minimized when no vehicle and no person are on the road, gradual dimming of the street lamps is achieved when the road has vehicles and persons, alarm can be automatically performed when the damaged street lamps are monitored, and energy saving is achieved to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a street lamp system based on PLC gradual dimming and machine vision. Background technique [0002] As an important tool for road lighting, street lamps consume a huge burden on the power grid. In the middle of the night, in some small and medium-sized cities in my country, there are very few pedestrians and vehicles, and there are few pedestrians and vehicles on the road after 2 o'clock in the morning in large cities, but the street lights are still full-power lighting, and when the street lights are damaged, they cannot be timely. Carrying out maintenance will further expand the loss of electric energy. Since the street lights are unmanned and energy-consuming, it will be a waste of electricity to still work at full power during periods and road sections where there are fewer pedestrians and vehicles. At present, the sensor lamps on the market are mostly used in ho...

In the middle of the night, in some small and medium-sized cities in my country, there are very few pedestrians and vehicles, and there are few pedestrians and vehicles on the road after 2 o'clock in the morning in large cities, but the street lights are still full-power lighting, and when the street lights are damaged, they cannot be timely. Maintenance will further expand the loss of electric energy

Since the street lamps are unmanned and energy-consuming, it will be a waste of electricity to still work at full power during periods and road sections where there are fewer pedestrians and vehicles

At present, the sensor lights on the market are mostly used in home and construction, and require independent sensors and controllers. Considering the high cost and single sensor information, they cannot be used in a large number of street lighting systems.

In order to solve the above problems, the present invention proposes a street light system based on PLC gradual dimming and machine vision, which uses road monitoring cameras instead of sensors to collect road surface information, which saves a lot of costs; at the same time, it solves the problem of single information from traditional sensors
