Description
Technical field
The present invention relates to a kind of method for controlling street lamps, especially relate to a kind of method carrying out road speed monitoring by street lamp radio-frequency technique.
Background technology
The streetlamp management system of particularly small and medium-sized cities, China most cities all uses clock, light-operated or better simply automatic control system, in this extensive way to manage, especially at the unfrequented road of large parking lot or pastoral area, forest zone, there is the problem that ten openings still located by street lamp without car or people's process for a long time, not only cause the biggest energy consumption to bear to roadway illumination, also disagree with the energy-conserving and environment-protective theory currently advocated.
A kind of lamp light control system (application number 201320540843.1) utilizing REID of Chinese patent is although disclosing the opening and closing being controlled street lamp by radio-frequency technique, but it exists techniques below defect:
(1) prior art does not set concrete condition by the unlatching of radio-frequency technique control street lamp, if the use time of radio-frequency technique is set according to night hours, so can omit some extreme weathers, such as sandstorm weather and foggy weather so that radio frequency controls can not adapt to environment in time.
(2) street lamp controlled in certain region by radio-frequency technique in prior art is turned on and off, if so this region sets excessive, still can cause the loss in vain of electric energy；If when region sets too small (as arranged radio-frequency card reader on each street lamp), it will make construction cost the highest, it is unsuitable for promoting.
(3) prior art uses radio-frequency technique only to control certain region street lamp all light, but do not control the time that this region street lamp extinguishes, if by setting radio-frequency card reader street lamp in this region of automatic distinguishing after reading N minute after radio-frequency (RF) tag, if that vehicle is when breaking down in this region, street lamp more than N minute after or can automatic distinguishing, by extremely disadvantageous in night human pilot maintenance and emergency.
Additionally, current domestic radar velocity measurement is all based on doppler principle, capacity of resisting disturbance is poor, and following interference source (include naturally occurring and artificially cause) all can cause radar meter error in reading or performance to reduce.
1, landform；Radar wave cannot pass through the object of major part solid-state, including leaves.Glass also can reflect radar wave, therefore when radar is launched by cruiser glass, measures distance and can shorten.
2, rain；Rain can absorb and disperse radar signal, and this will result in the shortening measuring distance, the speed that velocity readings is raindrop simultaneously likely obtained.
3, electronic noise；Electronic noise interference source has neon light signal, radio wave signal, power line, transformator etc..These interference will make measurement Distance Shortened, and cause error in reading.After these interference are detected, radar will show " RFI ", and reading will no longer be shown simultaneously.
4, automotive ignition noise；The electronic system of the automobile that one noise is the biggest will cause the fluctuation of service of radar.
5, fan noise；When radar is launched in cruiser, fan noise is the problem that modal Doppler radar runs into.Having sub-fraction radar wave by glass-reflected to car, they will capture the noise of fan, so that producing mistake during radar surveying.
6, angular error；Doppler radar only just can accurately be measured when with target carriage direction on one wire.If there is certain angle during measurement, there will be angular error, display speed will be lower than actual speed.Angular error is remaining profound proportional to angle.
7, from the interference of radio transition equipment；Near stronger radio transmitter be likely to the measurement of radar to be produced impact.Then represent as radar asorbing paint " RFI " and had detected that interference.Now, no longer show that any speed is to prevent the reading of mistake.Interference source is probably the vehicular radio on this car, or neighbouring transmitting equipment, or illegal radio interference device.
As can be seen here, on existing road there is error in velocity radar use, it is impossible to the true speed reflecting vehicle, and the existing mode that tests the speed cannot keep fixing speed by active warning human pilot when overspeed of vehicle, it is to avoid the generation of overspeed situation.
