Description
Technical field
The present invention relates to a kind of subregion controlled function unit of electric lighting control system, particularly a kind of have a picture circle function, and the electric lighting zone control system addressable description repeater of addressing function is arranged again.Be applicable to the electric lighting control system in a plurality of rooms or zone, making can name when needed to special room or zone carries out independent control.So-called room is meant any space for people's activity, and so-called zone is meant outside segment space in the room or the room and encloses.
Background technology
Progress along with electronic devices and components and electron controls technology, electric lighting technology, developed into digitized control system, wherein the most representative with the digital address light interface (Digital Addressable Lighting Interface is called for short DALI the America and Europe) of the annex E institute standard of IEC60929.This is former to be one and to be controlled to be the standard of purpose with adjusting brightness of fluorescent lamp, but because it is reliable, simple, reasonable price and the control system standard that covers all electric lighting systems that develops into gradually.Especially in the face of the global energy and environmental issue, power-saving technology becomes more and more important, and illuminator that can automation control also necessitates gradually.
Digitized electric lighting control system, initial all is the extension of calculator technology, utilize the Lighting Control Assembly of controlling as universal serial bus control information transmissions such as networks, its function is no doubt very strong, but price Tai Gao and unreasonable, thereby be restricted, only be applied to some special purposes and can't popularize.
Digital address light interface system is to develop successfully in Europe, is accepted by the world gradually again.Its framework is made up of a bus power source supply, at least one controller and the light fixture that possesses digital address light interface trusted device basically.Each digital address lighting circuit can be controlled maximum 64 independent light fixtures, when initial setting, and all designated address code name of each light fixture.Address according to this, system can assign instruction respectively to each light fixture.But when practical application, light fixture should divide into groups earlier, with these group data deposit in deposit within each light fixture in after, shown in European patent EP 90100465.6 (USPAT5352957), just can directly be that object is assigned instruction with the group.A loop can be set 16 groups (0～15) at most, and each light fixture can belong to several groups simultaneously, and still, this will see real system and decide that some product only allows to set a group.
The utilization of group is very convenient and important.For example each room is a group at least, and like this, controller could be controlled separately this room integral body, and the controller in this room also must preestablish its control group, so could correctly assign instruction and the unrest of can not wadding a quilt with cotton.An office supposes that it comprises several rooms and a meeting room for another example.In order to meet requirements of saving energy, each room must be able to be controlled separately, enable nobody the time close illumination automatically or reduce brightness.The light in each room just must be given a group code name separately if desire control separately, and controller, the transducer that the room is relevant also must be set identical group code name therewith.Light in the meeting room then may need to be divided into 3 groups at least, and for example top, dais, conference table top reach the both sides wall lamp and respectively are one group, to adapt to different needs such as speech, discussion, multimedia projection, bulletin.For convenient each group light is directly assigned instruction, special-purpose group controller can be installed in each room, as long as press the group button of group controller, just this group light fixture can be accepted instruction, certainly these associations must pass through and preestablish, otherwise the light fixture of controller and Be Controlled just can't link.The group technology of controller can be with reference to German patent DE 4327809.4, and (USPAT.5544037) general common group controller has 4 group options buttons.
Grouping can be organized each light and be adjusted to suitable brightness respectively after finishing, and forms a whole lamplight scene.Some place, for example multi-functional conference room may need several different lamplight scenes to adapt to different needs.Puzzlement for fear of frequent adjustment, can utilize the lamplight scene controller, data pre-storages such as the group that each each lamplight scene is relevant, brightness are in internal memory, need only press the scene options button during use, just original setting of can recalling, common lamplight scene controller generally has 4 to 8 scene keys available.
The addressability of digital address light interface system is its characteristic, and the grouping of whole system, scene setting, light modulation are all based on this.But the work of its initial setting grouping, set scene, setting brightness is very complicated sometimes, needs professional and specific purpose tool just can finish.
Can there be 64 controllers in a digital address light interface system loop, and each controller all has the controlling object of each controller of its individual address (transducer also is a kind of controller) to preestablish.Show via practical application experience, a digital address light interface loop, its light fixture can only be divided into 16 groups at most, in fact often is not enough, thereby forms a kind of restriction.Just be unable to cope with when for example more or lamplight scene is more complicated when the room number, and must increase another loop.
In order to remove setting program because of dividing into groups the limited inconvenience that causes and exempting complexity, Chinese patent application numbers 200610076528.2, name is called electric lighting control system and the control method that separates with the description repeater, be the patent application that proposes by same Applicant of the present invention, proposed a kind of electric lighting control technology scheme.This technical scheme does not serve as the control basis with the indivedual addressing of each light fixture, and with a kind of description repeater, the universal serial bus of control information transmission is drawn the boundary separate, and forms the isolated area space naturally.Its communication protocol, instruction is divided into system command group and regional space order bloc, system command can be passed through the description repeater, the regional space instruction is then only effective in regional space, can not cross the description repeater, make the instruction of system command and regional space respectively take charge of its duty, exempted complicated setting work, the execution work in its regional space that is defined by the repeater of demarcating that each regional space controller is very natural.Though be illuminator cloth build, keep in repair, expand and control aspect, all be explicit, come into plain view.
In order to meet the needs and the practicality of illumination control practical operation, this technical scheme is a controlling object with room or zone directly.Utilize a kind of description repeater devices, the digital information transmission bus is separated be independent partitions separately.System command can be passed through this repeater and be forwarded; The zone instruction then can not be passed through this repeater and be blocked, can only be in the regional space that the description repeater defines effectively.Various regional space internal controller and sensing controler then are designed to space, a sending zone instruction as personnel's detector, because the regional space instruction can't be passed through the description repeater, can not disturb its affiliated area space facility in addition naturally.The personnel's detector in room for example records no personnel's activity and desire when turn-offing light, and next room is unaffected.
This technical scheme when being applied to remote controller, more can highlight its convenience.At the remote controller that reaches described in German patent DE 4327809.4 (USPAT5544037) and the European patent EP 91201071 (USPAT5565855), all need remote controller is set, therefore, if have when chummery does not need remote controller, then the remote controller in each room all needs special the setting, each other can not be general.According to this Chinese patent application number 200610076528.2 technical schemes that provide, its remote controller then must not set and not have region limits, can work in any regional space.The communication protocol of this electric lighting control system is divided into two groups with instruction, and one is the system command group, and another is the regional space order bloc.
For system command, the description repeater will carry out relay function.The relay function of description repeater can for unidirectional also can be for two-way, for the control of the light fixture in the general living space, folk prescription gets final product to relaying.Reverse transmission can be in order to the repayment fault message.But for application among a small circle, whether operate as normal is open-and-shut thing to light, and Auto-Sensing is also inessential, and therefore in order to reduce cost, unidirectional (forward) relaying can be satisfied the demand.
For regional space instruction, the relay function of description repeater will be ended, and forms blocking-up in fact, so the regional space instruction can only be in the description repeater is the regional area on boundary effectively.
Communication protocol free Bytes length or byte content, also can the two and get and classified, for ease of relatively, will be that embodiment describes with instruction with digital address light interface (DALI) compatibility, total system broadcasting instructions for example of the present invention can be decided to be two bytes, and first byte is FF.
Its broadcast system commonly used instruction is as shown in table 1,
| Turn-off | FF00 | 11111111?00000000 |

Possess trusted, decoding and drive unit in the controlled light fixture to accept and execution command.Regional space controller, sensing controler, then based on emitting area space instruction, thereby its control action is only limited within its space, region, and must not carry out setting program at chummery not.
All can send the device of instruction, all possess collision detection capabilities, and when collision took place, electronegative potential was preferential, and high potential is retreated.
This description repeater, possess relaying and buffer stock function, when collision takes place, if secondary is sent and need be retreated among the description repeater, the system command information of carrying out in the relaying will be interrupted, only its input is then unaffected, and its command code is then proceeded decoding and is deposited in the internal memory, waits for that an appropriate time continues to retransmit afterwards again.
This electric lighting zone control system can be isolated each regional space, make total system, office of company for example, can accept system command, simultaneously in each regional space, for example all departments' subregion, be responsible for chamber, meeting room etc. and can the space, receiving area instruct the light of each comfortable regional space inner control all departments, this regional space lamp light control system, removed digital address light interface lamp light control system, the puzzlement of packet limit (maximum 16 groups), make the many lamplight scenes light control of many rooms, also be easy to realize.
But also there is its shortcoming in above-mentioned system, in the real life, when starting lamp light control system, particularly can control the lamp light control system in a plurality of rooms, does not often need total system to start simultaneously, and only need start specific room.For example the personnel of certain department will work overtime, and only need start this department's light when entering office and get final product; Or when coming back home, the light in the bright parlor of only looking on the bright side of things, other room keep putting out.This functional requirement need be assigned the ability of instruction to each space, specific region respectively, that is each space, specific region or room, needs a particular address.But the present invention proposes the addressable again addressable description in a kind of separated region space repeater devices at the demand, and the independence control in space, specific region is achieved.
