Description
Technical field
The utility model relates to a kind of Light Control Unit based on bus.
Background technology
Along with the continuous development of modern architecture science and technology and popularizing of information-based equipment, the intellectuality of control appliance has become the trend of current architectural development in the modern architecture.But for a long time, intelligent lighting equipment is out in the cold always at home, and most of buildings still adopt traditional illumination control mode, and not only bad for centralized monitor and management, and efficient is very low in the use of electric energy, has wasted a large amount of electric energy.
At present, some compact illumination control system that occur on the market can realize functions such as the control of local and far-end light fixture, area illumination, timing switches, but its controlled function is single, also belongs to artificial control to a great extent, does not realize automation and Based Intelligent Control.Therefore developing a kind of lighting system concentrated and Based Intelligent Control is the demand in market.
Summary of the invention
The purpose of this utility model provides a kind of Light Control Unit based on bus, realizes the unified control of long-distance intelligent of lighting system, not only plays energy-conservation effect, and is convenient to user's unified management, use, has market value preferably.
The utility model is achieved in that a kind of Light Control Unit based on bus, it is characterized in that: comprise PC 1, bus interface module 2, MCU 3, switching circuit 4; Described PC 1 is connected with MCU 3 by bus and bus interface module 2, and the output of described MCU 3 is connected with switching circuit 4.
The utility model can effectively solve the problem of storied building light real-time control management, saves energy and useful life of prolonging lighting apparatus effectively, and have characteristics such as low cost, low-power consumption, easy for installation and reliability height.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Fig. 2 is the schematic block circuit diagram of the utility model embodiment one.
Fig. 3 is infrared detection module principle figure.
Fig. 4 is the schematic block circuit diagram of the utility model embodiment two.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides a kind of Light Control Unit based on bus, it is characterized in that: comprise PC 1, bus interface module 2, MCU 3, switching circuit 4; Described PC 1 is connected with MCU 3 by bus and bus interface module 2, and the output of described MCU 3 is connected with switching circuit 4.
In the utility model embodiment one as shown in Figure 2, described MCU 3 also connects infrared detection module 5, and described infrared detection module 5 adopts passive infrared detecting head to sense when promptly the someone arrives behind the infrared radiation output output high level, and during unmanned the arrival, output low level.The pre-driver buffer that this triggering signal is connected into through four Schmidt triggers reaches the pulsewidth discriminator that is linked to each other and be connected into by monostable flipflop, d type flip flop, be delivered to MCU through reverser, design had both strengthened the driving force of system like this, guaranteed again simultaneously that the logic current potential of exporting with infrared detector cell is consistent, and had antijamming capability.Adopt bus to connect in addition, the simple expansibility of system line is good,, also is connected with Network Interface Module 6 on the bus described in the utility model herein, can realize network management, monitoring like this.This shows that the utility model can have two kinds of control models, a kind of is by the PC centralized control, and a kind of is to utilize the infrared detection module to realize Based Intelligent Control.
In order to reach better power saving effect, present light fixture all adopts the LED illuminating lamp, according to statistics, reach equal illuminating effect, and the LED lamp is than incandescent lamp energy-conservation 90%.LED has characteristics such as power consumption is low, life-span length, Environmental Safety, and therefore in embodiment two, as shown in Figure 4, described switching circuit 4 is connected with LED driver module 7.We adopt the AMC7140 chip for driving that signal is amplified to the driving that proper voltage realizes lamp in the present embodiment.
In addition, the switching circuit described in the utility model examples of implementation 4 comprises and is used to control the relay of light power or the switching circuit of being made up of transistor.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
