Description
Technical field
The present invention relates to communication control fields more particularly to distributed generation resource for electrical domain, two-way especially with two-way
A kind of two-way two-way switch Direct Conversion three phase supply and communication device of switch and the common switching control of earthing switch and its control
Method processed.
Background technique
Power supply application field and need the power supply system application field of simple transmitting control information outdoors, as LED street lamp,
The application fields such as Tunnel Lamp or other conventional lamps generally pass through due to power supply line farther out and there are many uncertain factors
Mains AC is powered the power supply in lamps and lanterns, and is communicated and controlled by individual communication device or route.Example
Such as LED street lamp in application, need the brightness of street lamp is adjusted every several hours, i.e., so-called light modulation, which due to
Secondary energy-saving may be implemented, there is great economy and social effect.Brightness adjustment control mode mainly has four classes: by individually adjusting
(such as: 0-10V analog voltage control/PWM count word amount control/RS-485 number is logical for the control mode of light progress analog or digital
Letter control)；Light modulation and control mode are carried out by wireless communication, such as Zigbee communication and control；It does not need independent route and leads to
The mode that power line is communicated is crossed, such as PLC power line carrier, PLC；Control is timed by the timer of lamp interior；This
A little communications are all substantially that the power supply inside lamps and lanterns is communicated and controlled.
It realizes simple by the control mode technology of individual light modulation line, it can be achieved that being controlled together a certain group of lamp, that is, divides
Group control, such as the light modulation line of a 0-10V can control up to 200 or more lamps, but when engineer application especially
There is construction wiring hardly possible when being reconstruction of old circuit, wiring distance is remote, wire rod drawback at high cost, and dims the anti-sense of route
The poor ability for answering thunder to interfere, reliability be not high.PLC power carrier communication mode: pass through (i.e. every bar on each power supply at present
On lamp) installation power carrier communication module, that is, single-lamp controller realizes communication and control function, advantage are transferable semaphores
Very big, signal bi-directional, transmission speed is fast, and signal is transmitted by Alternating Current Power Supply line, without construction wiring again, without extra
Wire rod cost；But single-lamp controller is at high cost and complicated, and signal amplitude is too small, and vulnerable to interference, communication reliability is low, works as lamps and lanterns
Quantity is more, and single-lamp controller quantity is similarly more, and totle drilling cost is very high.If power line carrier, PLC is integrated into inside power supply,
Not only there is a problem of that power carrier chip and coupling decoding circuit cost are high, can also have power line carrier, PLC frequency with switch
Power source internal working frequency height is overlapped and the problem that can be disturbed, and bring EMI electromagnetic compatibility problem is difficult to handle, and design is difficult
Degree is high, and there has been no actual product batch applications so far.Wirelessly communicating (such as Zigbee), there are at high cost, communication is unstable, communication
Apart from short problem, it is also desirable to additional wireless communication device and antenna on lamp.If wireless communication is integrated into power supply, because
Outdoor power system has water proof type aluminum hull, it is necessary to stretch out an antenna from aluminum hull, waterproof and configuration aspects difficulty are big, cost is also high.
The common feature of three is to require fringe cost relatively high material or device.Timing dimming: timer is in power supply electrifying
When start to work, after the period of setting, i.e., adjustment power source internal electric current to reach required brightness, advantage is into
This is very low, is not required to external wire rod, controller etc., but due to can not with PERCOM peripheral communication, once setting timing strategies, Bu Nengbian
More, therefore be not suitable for the biggish street lamp application of summer in winter evening hours difference in length, be also not suitable for the application such as Tunnel Lamp.Engineering
It is the secondary energy-saving based on light modulation using most crucial demand, which only need to carry out unified tune to certain sections or certain group lamp
Whole (grouping control), does not need to control single lamp one by one；Semaphore very little when light modulation need to only issue simple light modulation hundred
Divide and compares signal；Dimming interval is long, generally primary every several hour adjustments；Therefore the demand of dimmer application is: semaphore is minimum,
Signal degree of transitivity is few, just needs to communicate when needing to adjust, can customize in advance light modulation Time controlling schema and in communication
When write-once to power source internal memory, do not need single lamp control and need to only be grouped control, avoid rewiring as far as possible；On
It states in four kinds of modes, light modulation demand is more conform in such a way that light modulation line is controlled, plc communication and wireless communication are significantly super
Actual demand has been crossed, and timing dimming is not able to satisfy the demand of communication adjustment, using few.
Summary of the invention
The shortcomings that for above scheme, the present invention propose a kind of two-way two-way switch Direct Conversion three phase supply and communication dress
It sets and its control method, feature is can be communicated by power line, signal amplitude is greatly and then communication is stablized, no redundant wire
Cost is suitble to transmitting little data amount, is suitble to low frequency time communication, is suitble to grouping control, and the power supply of lamps and lanterns side need to only expand inside
The function of single-chip microcontroller can be realized, it is simple and reliable, it is at low cost, be suitble to after the outdoor lighting transformation and transformation of three phase supply
Secondary energy-saving is also suitble to the application of new projects' secondary energy-saving and other field application, and overall cost is minimum, and economic benefit is very aobvious
