Description
Technical field
The present invention relates to a kind of street lamp control system, particularly relate to a kind of LED module street lamp control system.
Background technology
LED is high with luminous efficiency, color rendering good, high, the easy realization of long service life, reliability controls and multicoloured characteristics more and more are subject to people's attention, street lamp is as the Symbol in a city, day by day become a line of scenery line in city, particularly increasing country all formulates the rules of energy-saving and emission-reduction and the standard of lighting criteria recently, has more effectively promoted the development in LED street lamp market.
Yet, fast development along with the LED illumination market, one large focal spot of LED street lamp market Cheng Liaozhong enterprise contention share, hysteresis due to authoritative technical standard development, cause the very different of whole LED street lamp industry, make a general survey of current cable network LED street lamp control system, Modular LED street lamp control system particularly, basically be all that all LED street lamp modules hang on same fieldbus, the problem of bringing like this is, when module number is more, greatly increased the load of bus, and, be positioned at a module on a certain lamp stand if there is fault, just likely have influence on the reliability of whole network.Also have in addition a large amount of not with the LED street lamp of central control system, although this kind of street lamp some with light sensor and other intelligent diagnostics regulatory functions,, owing to there is no center-control, can only fight separately, be not easy to centralized management.
China Patent Publication No. is that CN201374845 discloses a kind of bus mode control LED street lamp based on power line carrier, the control system of this invention can be according to the setting of classifying of the grade of road and characteristics, automatically control road lamp switch, with the adjusting lamp brightness, and monitor in real time the service condition of street lamp and circuit, can also skip the switch that control system is manually controlled street lamp under special circumstances.But, if this LED street lamp is used in the modular street lamp system, the burden of the line bus that can increase electric power, add power line carrier power line used itself unreliable (the intrinsic impulse disturbances of power line existence itself), also easily be subject to various electrical equipment and disturb, and then caused the unstable of control system.
China Patent Publication No. is that CN201378891 discloses the wireless bus street lamp control system that a kind of GSM public network and ZigBee-network combine, the advantage of this system is to have saved signal cable, system is succinct, but because ZigBee is the wireless network of low rate, if modular street lamp quantity is many, can causes the node of ZigBee too much, and then cause wireless network data to block up, slow in reacting, the phenomenons such as response time delay.
