Description
Technical field
The present invention relates to a kind of illuminator, particularly a kind of intelligent illuminating system based on CAN bus.
Background technology
Fieldbus is the communication network for a kind of full dispersion between field instrument and control system and control room, total digitalization, intelligence, two-way, interconnected, multivariable, multiple spot, multistation, it has linked up the contact between production process Plant floor control equipment and between higher control and management layer as the basis of industrial data communication network.Because fieldbus has adapted to industrial control system to decentralized, networking and intelligentized development trend, it is once producing the focus that just becomes global automatic technology.Its appearance, has caused the automated system structure of current production and the deep reform of equipment.
Illumination is to utilize various light sources, illuminates the measure of work and life area or item, utilizes the title " natural lighting " of solar energy and skylight, utilizes the title " artificial light " of artificial light source.It is controlling of the quality and quantity to illumination use that illumination is controlled, and the use state of the various light sources including artificial light source and lamp is adjusted, to realize the concrete means of more comfortable, more graceful, more energy-conservation lighting environment.
Along with the raising of scientific and technological development and people's material, spiritual life level, illumination is not only to meet the requirement that people visually become clear, and also will meet the requirement of artistry, create colourful artistic conception, gives people to enjoy.Since within 1973, having there is in the world for the first time energy crisis; paying attention to gradually lighting energy saving in the world; and " green illumination " theory proposed; in the process of development Green Lighting Project, illumination is controlled and has been played very important effect, and this has also promoted the development of lighting control technique to a great extent.
CAN local area control net is to use at present one of fieldbus the most widely, it is a kind of multi-master bus, and on network, any one node all can be at any time sends information to other nodes on network on one's own initiative, and regardless of principal and subordinate, between node, have dividing of priority, thereby communication mode is flexible; Several mode transmission and the reception data such as CAN can be point-to-point, a point-to-multipoint (in groups) and overall situation broadcast; CAN adopts non-destructive position arbitration technique, and priority sends, and can greatly save the bus collision arbitration time, shows good performance under heavy load.Apply to the earliest auto industry, along with the development of CAN bussing technique, its utilization field is also constantly expanded, and nowadays, in fields such as robot, Numeric Control Technology, instrument and meter for automation, aircraft industry, can see the shadow of CAN.
Since within 1973, having there is in the world for the first time energy crisis; paying attention to gradually lighting energy saving in the world; and " green illumination " theory proposed; in the process of development Green Lighting Project, illumination is controlled and has been played very important effect, and this has also promoted the development of lighting control technique to a great extent.Traditional lighting control technique take manually as main, only can be realized simple switch control and brightness adjustment control in the control mode of illumination.Utilization is arranged on the electric parameter (voltage, electric current, frequency etc.) in light fixture loop, realizes brightness adjustment control.This traditional illumination control mode, function is simple, the complicated requirement that far can not meet current social development of wiring.Along with the development of computer technology, network communications technology, microelectric technique, field bus technique etc., utilize Fieldbus Intelligent node that lighting apparatus is formed to local operation networks, forming networking control will become the development trend of intelligent lighting control.Studying Just because of this fieldbus and control with illumination the technology combining, will be the needs of future development, therefore, is necessary that research illumination is controlled at the application on fieldbus.But CAN bus is again one of outstanding representative of fieldbus, therefore studying CAN bus has its great meaning to the control of illumination.This has not only promoted the development of intelligent lighting control technology, has also widened the application of fieldbus.
Summary of the invention
The invention provides a kind of intelligent illuminating system based on CAN bus, it can overcome the deficiencies in the prior art, realizes the information interchange of main and subordinate node, and the intelligent lighting control based on CAN bus, has realized intelligent lighting.
A kind of intelligent illuminating system based on CAN bus that the embodiment of the present invention provides, comprising:
Host node, for sending from the control information of node lamp by CAN bus mode, sends and starts modulating signal to multiple from node with the forms of broadcasting;
Described from node, receive control information and startup modulating signal that described host node sends, carry out described control information operation, revise from nodal information.
Described host node comprises receiver module, for reception server end send from the control information of node lamp.
Describedly from node, receive the control information that described host node sends and start modulating signal, also comprising, the control information receiving being unpacked to translation, and produce luminous lamp switch control signal and Timer Controlling signal.
This system also comprises interface module, for connecting external equipment.
