Abstract
The invention discloses an intelligent control system used for an LED (light-emitting diode) street lamp and based on a plc (programmable logic controller) and a power line carrier communication technology. Intelligent adjustment of street lamp equipment is really achieved. According to the system, automatic control and manual control are achieved by the plc, an integrated controller and a single-lamp controller control line; manual adjustment is achieved by a computer, the integrated controller and the single-lamp controller control line; the power carrier communication is adopted between the integrated controller and the single-lamp controller by, so that the intelligent control system is further optimized.
Description
One, technical field
The present invention is applicable to street lamp device reducing energy consumption, is particularly useful for the reducing energy consumption of heavy civil road lighting engineering.
Two, background technology
At present, existing street lamp device control method is: Artificial Control power save mode: be responsible for manually carrying out ON/OFF lamp according to switch lamp timetable by operator on duty and operate.Time control power save mode: be unique switch lamp foundation with the time, no matter how meteorological condition changes, all can only at regulation moment switch lamp, with seasonal variations manual intervention adjustment switching time.Optical-control energy-saving mode: carry out Dominating paths lamp switch by the difference of illuminance.These power save modes also exist comparatively significantly shortcoming, the ON/OFF lamp of most domestic city street lamp controls by each transformer (distribution box) decentralized control, although city street lamp runs special control line, only have controlling functions and monitoring cannot be realized, owing to can not control in strict accordance with outdoor natural light illumination, not only poor real, failure rate is high, and waste is serious.In addition, traditional control method will be asked for help and do not left the post, and controls the opening and closing of light in time, causes waste of energy to be very surprising due to Artificial Control error.And control cable and the electric power cable of current road lamp system are what to separate, waste a large amount of cables, also make troubles in construction aspect.
Three, summary of the invention
In order to overcome the deficiency of existing road lamp energy-saving system, reducing energy consumption to greatest extent, the invention provides a kind of Intelligent energy-saving solution.
1, the period controls and voltage control use, and according to the current waveform detected, whether automatic analysis street lamp normally starts (be fault or do not reach starting resistor).System can regulate automatically by the illumination requirement of the upper time after midnight, and light fixture utilization rate is adjusted to optimum state.Before midnight is run (maintenance high voltage) time after midnight with high illuminance state and runs (maintenance low-voltage) with low irradiance state.When dusk street lamp illumination system initiating switchup, electricity-saving appliance can export with normal line voltage, to guarantee that street lamp can normally start.After startup completes, street lamp power supply, road lamp power supply voltage can be adjusted to default before midnight magnitude of voltage by electricity-saving appliance.After entering the period time after midnight, voltage can be down to the default magnitude of voltage time after midnight by electricity-saving appliance automatically.Accomplish that electricity saving of road lamp rate is between 25%-40%.
2, based on power carrier communication, do not need again to set up network, as long as live wire, just can carry out data transmission.
Four, embodiment
Concrete scheme measure during native system application is: by the acousto-optic of plc collection in worksite and the illuminance of current signal Intelligent adjustment LED street lamp, is controlled the opening and closing of street lamp by plc; Also directly control signal manual adjustment illuminance and street lamp opening and closing can be sent by computer to Centralized Controller.First, by the collection to luminance signal, judging that street lamp illumination system is the need of unlatching by intelligent controller, running the soft start (be generally by tens of, even up to a hundred street lamps form the illuminator of a street) then being completed street lamp by power cell as needed.If street lamp normally starts, the road surface vehicle flowrate that the acoustic sensor that system is just installed according to road surface collects and the acoustical signal that pedestrian's flow sends send control information by intelligent controller, the size that variable reactance converter decides street lamp output voltage is controlled by power conversion unit, if the flow of real-time vehicle and pedestrian is larger, namely need the illumination of street lamp higher, the output voltage of system automatic adjustment height street lamp according to demand; If the flow of real-time vehicle and pedestrian is less, namely the illumination of street lamp does not need very high, and system will reduce the output voltage of street lamp automatically; If there is street lamp not start, system can according to the current waveform detected, automatic decision street lamp is that fault or voltage do not reach starting resistor, if trouble light, system is directly excised, if undertension, then continues boosting and starts.
What intelligent controller was chosen as its control mode of core of whole system is FUZZY ALGORITHMS FOR CONTROL, the external signal gathered is by amplifying, be input to after conversion in the microprocessor of controller, here the signal that we gather is light signal and voice signal two kinds, wherein light signal is used for controlling the start and stop of whole system, voice signal is then used for reflecting in real time the requirement of external environment condition, by the mode of fuzzy control, the data of collection are carried out process comparison, choose optimized control signal and exported.
Five, accompanying drawing explanation
Accompanying drawing is the LED street lamp intelligent control figure based on carrier communication.
