Description
Technical field
The present invention relates to electronic circuit, particularly relate to illuminator, illumination driving power source and controller thereof and control
Method processed.
Background technology
The intelligent illuminating system of control based on network is the focus of current research and application.In roadway illumination field,
Owing to networking is in large scale, network structure is various, and technology is increasingly complex, the most more has using value.
The mainstream scheme of the intelligent illuminating system of control based on network is the shape that existing communication technology uses module
Formula combines with illumination driving power source, to realize remotely controlling.As it is shown in figure 1, its ultimate principle is to pass through
It is distributed that server uses the radio communication systems such as GPRS (General Packet Radio Service) to control
Host node, if neglect the equipment such as the switch of the Internet transmission, mobile communication base station or facility and
Its communication process, then it is believed that this topology is Star Network, for the superiors' network of system.
Each host node general management is several to hundreds of individual from node.From node with lamp stand or light fixture it is typically
Unit, on a lamp stand one or several from node, host node and constitute second layer network between node.
Owing to lamp stand is distant, distribution situation is complicated, no matter uses traditional micropower wireless or electric lines of force carries
Ripple scheme, limited from node transmitting power due to as communication equipment, communication distance is relatively near, a lot of situations
Lower host node cannot directly control to this network distalmost end from node, generally require centre from node to logical
Letter information forwards.Therefore typically both undertake control task from node, also take on communication relay task, therefore
This network topology is extremely complex, may be star-like, tree-shaped, the topology such as compound.It is pointed out that master
Node administration is the hugest from the quantity of node, and this network is the most complicated, and performance is the poorest.
From node general management one or several driving power supplys, can use built-in or be placed on driving electricity
The mode in source.Typically drive the turning on light of power supply from node control, turn off the light, dim, or gather and drive power supply
Duty, gathers the electrical quantity driving power supply input and output.
Energy-conservation and intelligent two the important targets being illuminator and developing.But it is the most energy-conservation or intelligent
Target, all relevant with the networking performance of communication equipment.In this respect, there is many problems has to be solved,
Such as:
(1) illumination driving power source performs instruction reliability Shortcomings.Owing to using circumstance complication, number of devices
Measuring huge, the probability that instruction runs succeeded is it is difficult to ensure that reach absolutely, particularly in some key operations
On, such as turn on light, turn off the light, the action such as light modulation, if performing failure, this situation can bring severe use
Family is experienced, and also affects energy-saving effect.
(2) bulk equipment (illumination driving power source or various sensor, communication equipment etc.) is to operational order
Response time inconsistent, deviation is bigger.This situation is experienced except affecting user operation, also results in
Electro-metering is forbidden.Energy-conservation is the important target of intelligence system and the power of popularization.Particularly rising in recent years
Energy Management Contract (energy management contract, EMC) or state-private pattern
Business models such as (Public-private-partnership, PPP), it is likely to domestic roadway illumination field
The important model promoted.Under this background, Electro-metering just becomes extremely important accurately.For intelligence
Control system, except the special key lamp under bad weather condition operates, generally, turns on light, turns off the light
And the operating time of light modulation directly influences electricity consumption situation.For large batch of street lamp, perform this and use
The time deviation of electricity dependent instruction is the biggest, and the uncontrollability of electricity consumption is the biggest.For energy-saving scheme design,
Use and follow-up business model execution aspect can adversely affect.
The problems referred to above are mostly derived from the some shortcomings of the communication technology of large-scale application.Owing to condition of road surface is complicated,
The network topology variation of this scale remote networking, has star-like, netted, tree-shaped or compound, to list
Secondary communication, different topologys may need the relaying (route) that number of times differs.Add electromagnetic environment complicated,
Barrier obstruction, meteorological condition are changeable, a lot of in the case of, the communication of equipment room is difficult to accomplish absolutely to become
Merit.Generally require shake hands, retransmit, frequency hopping, route etc. may cause the method for time delay evade or reduce
The situation of this communication failure, this is just degrading the problems such as execution Time Inconsistency.Additionally, for scale
Application, the communication between host node and server is likely to there will be packet loss, Cuo Bao, the problem such as go offline.
Substantially, this falls within the deficiency of communication technology.
Solve the significant challenge that these problems are the intelligent illuminating systems of research and application networkization control.
