Description

A kind of Node Controller

Technical field

The utility model relates to Street lamps control technical field, specially a kind of Node Controller.

Background technique

LED has obtained huge development as forth generation lighting source in recent years, and the performance indicators such as light efficiency quickly improve And price rapid decrease, the application field of the routine such as display, Landscape Lighting is breached, in the directional lightings such as road lighting It applies more and more, increasingly there is competitiveness, China's street lamp control system mainly uses time-controlled mode at present, and one As timer have two kinds of timing modes of summer in winter, the time switch of street lamp may be implemented in this mode, but disadvantage is to set The fixed time is unable to adjust, and whens seasonal variations will appear switch lamp time and the unmatched phenomenon of conversion time round the clock, also can not Lamp condition is monitored, for this purpose, we have proposed a kind of Node Controllers.

Utility model content

The purpose of this utility model is to provide a kind of Node Controllers, to solve setting mentioned above in the background art Time be unable to adjust, whens seasonal variations, will appear switch lamp time and the unmatched phenomenon of conversion time round the clock, also can not be right The problem of lamp condition is monitored.

To achieve the above object, the utility model provides the following technical solutions: a kind of Node Controller, including control core Piece, electrically input connection electrical parameter Acquisition Circuit, the control chip are electrically bi-directionally connected debugging respectively and connect the control chip Mouth, carrier module and downloading and preparation interface, electrically output connects LED expansion module and light modulation output to the control chip respectively Interface.

Preferably, the electrical parameter Acquisition Circuit is made of current sampling circuit and voltage sampling circuit, and the electric current is adopted Electrically output connection controls chip for sample circuit and voltage sampling circuit.

Preferably, the light modulation output interface dims output interface by PWM and DAC light modulation output interface forms, the PWM It dims output interface and DAC light modulation output interface electrically inputs connection control chip.

Preferably, electrically input connects power module to the control chip.

Compared with prior art, the utility model has the beneficial effects that this kind of Node Controller, design is reasonable, practicability By force, by the circuits such as setting carrier module and light modulation output interface, it is based on electric power carrier communication technology, street lamp can be realized remote Process control switch, light modulation, inquire electric current and voltage, realize the monitoring to lamp condition.
