Description
Technical field
The present invention relates to Control on Communication field, particularly relate to a kind of single-phase bridge and exchange communication and electric supply installation and control method thereof.
Background technology
Application of power field and need the electric power system application of simple transmitting control information out of doors, as applications such as LED street lamp, Tunnel Lamp or other conventional lamp, because supply line is comparatively far away and there is many uncertain factors, generally by mains electricity, the power supply in light fixture is powered, and undertaken communicating and controlling by independent communicator or circuit.Such as during LED street lamp application, need to regulate every brightness to street lamp in several hours, i.e. so-called light modulation, which, owing to realizing secondary energy-saving, has great economy and social effect.Brightness adjustment control mode mainly contains four classes: the control mode (as: 0-10V analog voltage control/PWM discrete control/RS-485 digital communication controls) of being carried out analog or digital by independent light modulation line; Light modulation and control mode is carried out, as Zigbee communication and control by radio communication; Do not need independent circuit and carried out the mode that communicates by power line, as PLC power line carrier, PLC; Timing controlled is carried out by the timer of lamp interior; These communication be in fact all to light fixture inside power supply communicate and control.
Realize simple by the control mode technology of independent light modulation line, can realize controlling together a certain group of lamp, namely divide into groups to control, the light modulation line of a such as 0-10V can control the lamp of nearly more than 200, but when engineer applied especially reconstruction of old circuit time to there is construction wiring difficult, wiring distance is far away, the drawback that wire rod cost is high, and the poor ability of the anti-induced lightening interference of light modulation circuit, reliability is not high.PLC power line carrier, PLC mode: at present by each power supply (namely on every bar lamp) install power line carrier, PLC module additional and single-lamp controller realizes communicating and controlling functions, advantage is that transferable semaphore is very large, signal bi-directional, transmission speed is fast, signal is transmitted by Alternating Current Power Supply line, without the need to wiring of again constructing, without unnecessary wire rod cost; But single-lamp controller cost is high and complicated, signal amplitude is too little, is easily disturbed, and communication reliability is low, and when light fixture quantity is more, single-lamp controller quantity is many too, and total cost is very high.If power line carrier, PLC is integrated into inside power supply, not only there is power carrier chip and the high problem of coupling solutions decoding circuit cost, also can there is the problem that power line carrier, PLC frequency overlaps with Switching Power Supply internal operating frequencies height and meeting is disturbed, the EMI electromagnetic compatibility problem brought is difficult to process, design difficulty is high, not yet has the application of actual product batch so far.There is the problem that cost is high, communication is unstable, communication distance is short in radio communication (as Zigbee), also needs additional wireless communication device and antenna on lamp.If radio communication be integrated in power supply, because outdoor power system is with water proof type aluminum hull, an antenna must be stretched out from aluminum hull, waterproof and configuration aspects difficulty are large, cost is also high.The common feature of three is the material or device that all need fringe cost higher.Timing dimming: timer is started working when power supply electrifying, after the time period of setting, namely the electric current of power source internal is adjusted to reach required brightness, advantage is that cost is very low, does not need external wire rod, controller etc., but due to PERCOM peripheral communication cannot be followed, once setting timing strategies, can not change, therefore be not suitable for the larger street lamp application of evening hours difference in length in summer in winter, be also not suitable for the application such as Tunnel Lamp.The most crucial demand of engineer applied is the secondary energy-saving based on light modulation, and this demand only need unify adjustment (grouping controls) to some section or certain group lamp, does not need to control one by one single lamp; During light modulation, semaphore is very little, only need send simple light modulation percentage signal; Dimming interval is long, generally every adjustment in several hours once; Therefore the demand of dimmer application is: semaphore is minimum, signal transmission number of times is few, need just to need communication when adjustment, can customize in advance light modulation Time controlling schema and communication in write-once to power source internal memory, do not need single lamp to control and only need divide into groups to control, avoiding rewiring as far as possible; In above-mentioned four kinds of modes, the Method compare being undertaken controlling by light modulation line meets light modulation demand, and plc communication and radio communication greatly exceed actual demand, and timing dimming can not meet the demand of communication adjustment, and application is few.
Summary of the invention
For the shortcoming of such scheme, the present invention proposes single-phase bridge that a kind of interchange AC line by bridge rectifier and Switch Control carries out communicating and exchanges communication and electric supply installation and control method thereof, feature can be communicated by power line, signal amplitude is large and then communication is stable, without redundant wire cost, be applicable to transmitting less data volume, be applicable to low frequency communication, be applicable to grouping to control, the function that the power supply of light fixture side only need expand inner single-chip microcomputer can realize, realize simple and reliable, cost is low, economic benefit highly significant.
