Technical field
The invention belongs to lighting field, particularly a kind of method for controlling street lamps based on power line transmission control signal.
Background technology
Street lamp is content indispensable in city illumination, at some Important Sections, by control centre, Long-distance Control is carried out to all street lamps simultaneously, varied about the improvement project of street lamp at present, as Chinese invention patent application 201310228203.1 provides a kind of controller for road lamp, comprise street lamp and induction installation, described induction installation comprises infrared inductor, described infrared inductor is connected with road lamp power supply controller, and power-supply controller of electric is connected with the power supply of street lamp; Described induction installation is installed on street lamp; Described induction installation is connected with timing delayer; The feature of this controller for road lamp is that structure is simple, being connected, sensing that the vehicle that Lu Shangyou travels just can be opened through out-of-date, can playing electricity-saving function, reduce the wasting of resources by induction installation with power-supply controller of electric.
And for example Chinese invention patent application 201410275143.3 provides a kind of roam lamp control device, relates to control device of street lamp manufacturing technology field, it comprises contactor, start button and stop button, also comprise microcomputer controller and the change over switch for manual/auto conversion, the input of change over switch is connected with a pole of power supply, the automatic end of this change over switch is connected with the input of microcomputer controller, it is manually held and is connected with stop button one end, one end of the normally opened contact parallel connection of the other end of stop button and start button and described contactor is connected, the other end of normally opened contact parallel connection of start button and contactor is connected with the output of microcomputer controller and is connected with coil one end of contactor, the coil other end of contactor is connected with another pole of power supply by microcomputer controller.It can solve and adopt power saver, reactive-load compensator can produce humorous wave interference when carrying out energy-conservation to street lamp, the light fixture low problem high with maintenance cost in useful life.
Current street lamp is provided with controller for road lamp greatly, be used for controlling the switch of street lamp and brightness etc., can see two pieces patent application above, this controller for road lamp just controls the switch of street lamp mostly simply by photodetection ambient brightness, the same day is subduing (the evening draws on or the cloudy day), controls street lamp and automatically opens, and when the colour of sky brightens, then automatically close street lamp, thus reach the object of saving electric power.But this control mode is more single, and be only directed to man-to-man control object.
Along with the development of city extension, and the complexity of road conditions and polytropy, the control of street lamp starts the future development towards networking control, but should be used for from current, mostly realize by GPRS module, in the specific implementation, for each street lamp configures separately a GPRS module, all GPRS module communicate with control centre again, can imagine that cost is very high, and operationally, GPRS communication also produces communication cost, further increase use cost, limit the popularization of networking control.
Be directed to this, Chinese invention patent application 201210450683.1 provides a kind of controller for road lamp, it comprises wireless communication module, central processing module, power module, control module and signal acquisition module, wireless communication module, central processing module, control module and signal acquisition module are all electrically connected with power module, and central processing module is electrically connected with wireless communication module, control module and signal acquisition module respectively; Described signal acquisition module comprises current signal process submodule, photoinduction submodule; The communication chip that described wireless communication module adopts is radio frequency chip.This kind of scheme provide a kind of can adapt to different sections of highway well energy saving requirement and the low controller for road lamp of networking control cost.
But aforementioned schemes, when implementing, needing to be equipped with wireless communication module to each street lamp, except producing higher use cost, when improving, larger quantities also being needed for existing street lamp illumination system, being still further improved.Namely inventor is the current condition for Street lamps control aspect, and by attempting for a long time and studying, this case produces thus.
Summary of the invention
Object of the present invention, be to provide a kind of method for controlling street lamps based on power line transmission, it is without the need to increasing communication module, and networking control cost is low.
In order to reach above-mentioned purpose, solution of the present invention is:
Based on a method for controlling street lamps for power line transmission, networking control is carried out to street lamp module; The content of described control method is: each street lamp module be connected the first power line carrier module between power line, the second power line carrier module is connected between power line with control centre, control information is sent into the second power line carrier module by control centre, control information to be coupled in power line to transmit by described second power line carrier module; Control information modulation is separated by described first power line carrier module in power line, sends into street lamp module.
Above-mentioned each street lamp module all has the numbering that is different from other street lamp module, the control information that described control centre sends is with numbering, when each street lamp module receives control information, first judge whether the numbering of this control information numbers corresponding with self, control information during correspondence is controlled, not to this control information during correspondence.
Above-mentioned power line carrier module adopts SENS-00 flush bonding module.
Above-mentioned street lamp module comprises the controller, LED driver and the LED group that are linked in sequence, and described controller connects described power line carrier module.
Above-mentioned LED group is arranged by several LED lamp bead and forms.
Above-mentioned LED lamp bead is word order.
After adopting such scheme, the present invention utilizes existing power supply facilities, because street lamp must adopt power line to power, control centre also needs to access electric power system simultaneously, utilizes the objective condition that street lamp and control centre couple together by power line, adopt power line transmission technology popular at present, power line is utilized to realize the transmission of control information, with low cost, and the intercommunication mutually between street lamp module can be realized simultaneously, the refinement more of more existing intranet network, content is abundanter.
Embodiment
Below with reference to embodiment, technical scheme of the present invention is described in detail.
