Description
Technical field
The utility model relates to a kind of LED street lamp control system, more particularly, relates to a kind of LED intelligent street lamp control system based on power line carrier communication.
Background technology
PLC=Power Line Carrier, power line carrier (PLC) is the distinctive communication mode of electric power system, electric line carrier communication refers to and utilizes existing power line, by carrier system, analog or digital signal is carried out to the technology of high-speed transfer.Maximum feature is not need again to set up network, as long as live wire just can carry out data transmission.
But electric line carrier communication is because there is following shortcoming, cause PLC mainly to apply---" electric power online " fails large-scale application: (1), because distribution transformer has iris action to power carrier signal, so power carrier signal can only transmit in a distribution transformer regional extent; (2), between three-phase power line, there is very large-signal loss (10dB-30dB).General power carrier signal can only be uploaded in the single-phase electricity line of force defeated, but when communication distance is very near, difference is alternate may receive signal; (3), that unlike signal lotus root is closed mode is different to power carrier signal loss, lotus root is closed mode, and wired-ground lotus root closes and line-center line lotus root is closed.Line-ground lotus root is closed mode and compares with line-center line lotus root mode of closing, and power carrier signal is lost tens dB less, but line-ground lotus root is closed the not all regional power system of mode and is all suitable for; (4), the impulse disturbances of power line existence because having itself.The alternating current using at present has 50HZ and 60HZ, the cycle is 20ms and 16.7ms, in each ac cycle, there are two minor peaks, two minor peaks can be brought impulse disturbances twice, be on power line, to have fixing 100HZ or 120HZ impulse disturbances, interference time, about 2ms, must be processed because determining interference.Have a kind of waveform that utilizes to cross the method for carrying out transfer of data in the short time of 0, but short owing to spending 0 time, bad control is synchronizeed in practical application with AC wave shape, and modern communication Frame is long again, so be difficult to application; (5), power line causes high reduction to carrier signal.When on power line, load is very heavy, line impedance can reach below 1 ohm, causes the height of carrier signal is cut down.In practical application, when power line is unloaded, point-to-point carrier signal can be transferred to several kilometers.But when load is very heavy on power line, can only transmit tens meters.
Although technical problem, along with the development of time, finally can be solved and be overcome, from the situation of current domestic broadband networks construction, leave time and the space hard up of PLC for.Since 2000, Ge great operator releases the multiple wideband switch-in business such as ADSL, optical fiber, wireless network on a large scale, leaves the living space of power line communications for, constantly by other access waies, is compressed.Now, PLC, except applying to some extent on remote meter reading, has not had brave words originally.
But along with the rise of this topic of household intelligent system, also to PLC, brought a new stage.In current household intelligent system, the household intelligent system that the PC of take is core is held in both hands by people's heat.The idea of this system is exactly, along with popularizing of computer, can need data to be processed all to give computer all household electrical appliance and complete.So just need between household electrical appliances and PC, build a data transport network, everybody has an optimistic view of wireless now, but in this environment of family, " wall is many " this feature is having a strong impact on the quality of wireless transmission, and particularly in villa and duplex house, this defect is more obvious.If set up private wire network network except increasing cost, the position of household electrical appliances also cannot arbitrarily be moved from now on so.The maximum feature of PLC: do not need again to set up network, as long as live wire, just can carry out data transmission, become undoubtedly one of preferred plan solving this Smart Home transfer of data, simultaneously, because transmit in this scope of data Jin family, 5 large puzzlements of constraint PLC application will existed, and we also can first be connected to PC and then control household electrical appliances mode realizes the Long-distance Control to household electrical appliances by legacy network, in addition, the cost of PLC modulation /demodulation module is also far below wireless module.
Through retrieval, have for existing LED street lamp control system and carry out improved technical scheme openly, China Patent No. ZL201220077405.1, Granted publication day is on October 31st, 2012, invention and created name is: a kind of LED street lamp of wireless control light modulation, this application case relates to a kind of LED street lamp of wireless control light modulation.LED intelligent street lamp control system is on the market with time control, light-operated in the majority, compatible not enough, affected by season, weather and human factor, and automatic management level is low, very easily causes energy waste.The application's case includes LED power supply and the LED light source being connected on it, and LED power supply is gone between and is connected with wireless receiver by light modulation; Signal transmission between wireless receiver and wireless launcher; On wireless launcher, be connected with controller.The application's case is to utilize wireless transmission, receiver module, reach the object of controlling LED dimming power source, but this application case Shortcomings part still: and wireless signal is easily subject to the impact of external environment, for example " wall is many " this factor, in addition, the cost price of wireless module is also a problem.
