Intelligent lighting power distribution control box with built-in controller

Abstract

The invention relates to the technical field of lighting power distribution control boxes, in particular to an intelligent lighting power distribution control box with a built-in controller, which comprises a power distribution unit, a direct-current power supply unit, an RS485 relay output module unit, a main control unit, a human-computer interface unit, a 4G / 5G router, an illuminance sensor and a metal structure box shell, the direct-current switching power supply is used for converting a 220V alternating-current power supply into a 24V / 12V direct-current power supply and converting the 220V alternating-current power supply into a 5V direct-current power supply, can be connected with a computer and a PC terminal through the Ethernet, and modifies control parameters of a power distribution loop through the intelligent cloud platform remote computer, the PC or the mobile phone terminal. The human-computer interface touch screen unit is a 4.3-inch or 5-inch touch screen with an HDMI (High Definition Multimedia Interface) interface, the illuminance sensor is a general illuminance sensor with 485 communication, and the 4G / 5G router is a general router. The control box is convenient to install, intelligent management and control can be conveniently achieved, energy consumption and operation and management cost can be effectively reduced, and meanwhile a traditional control box can be conveniently transformed and upgraded.

Description

technical field [0001] The invention relates to the technical field of lighting power distribution control boxes, in particular to an intelligent lighting power distribution control box with a built-in controller. Background technique [0002] With the rapid development of the national economy, the highway mileage is getting longer and longer. As a part of the highway, the number of tunnels is increasing, and the mileage is also getting longer and longer. Then the lighting in the highway tunnel needs to be solved. The main problem is the visual problem of driving safety: on a sunny day, when the driver enters the tunnel from the outside of the tunnel, due to the huge difference in brightness between the inside and the outside, when looking at the tunnel entrance with insufficient lighting from the outside of the tunnel, only one can be seen. A black hole or a black frame. In order to eliminate this black hole or black frame phenomenon, the brightness of the road surface mus...

Problems solved by technology

[0004] Another problem is energy saving. The waste of electric energy due to unreasonable control methods: At present, the tunnel lighting control method is mainly controlled by five levels of sub-loops: sunny, cloudy, rainy, night, and late night. Since the current control device cannot realize intelligent tracking and real-time control, As a result, the lighting effect is poor, or the waste of electric energy is large. Regarding the waste of electric energy caused by design maintenance coefficient and redundancy: usually when designing the power of lamps, a certain maintenance coefficient must be considered to ensure that when the brightness of the light source is attenuated and the lamps are damaged during operation When the brightness drops to more than 30% due to pollution, the illumination intensity can still meet the specification requirements. Therefore, in order to ensure that the tunnel lighting can always meet the specification requirements, a certain degree of redundancy should also be considered during design. In this way, the design calculation power is 100W. The light should be 150~170W. During the actual operation, if the light is turned on on one side, the brightness will not be enough. If the light is turned on on both sides, the over-illumination will be serious, which will not only cause a large waste of electric energy, but also cause visual problems in driving safety.

[0005] At present, the status quo of the beautification and lighting of cities and parks in my country and the management of street lighting are mainly: relying on manual management, switching lights requires staff to switch on and off at fixed points, and staff are still required to be on duty after the early morning. When street lights fail, they cannot be timely processing, virtually increased a lot of manpower, material and financial resources
