Chinese patent is a kind of utilizes the lamp light control system of REID (application number 201320540843.1) although disclose the opening and closing being controlled street lamp by radio-frequency technique, and it still exists following technological deficiency:
(1) concrete condition is not set by the unlatching of radio-frequency technique control street lamp in prior art, if the service time of radio-frequency technique is set according to night hours, so can omit some extreme weathers, such as sandstorm weather and foggy weather, make radio frequency control to conform in time.
(2) street lamp controlled in certain region by radio-frequency technique in prior art opens or cuts out, if when the setting of this region is excessive like this, still can cause the loss in vain of electric energy; If when region setting is too small (as arranged radio-frequency card reader on each street lamp), construction cost will be made too high, be unsuitable for promoting.
(3) prior art uses radio-frequency technique only to control certain region street lamp entirely bright, but do not control the time that this region street lamp extinguishes, if by the street lamp in this region of automatic distinguishing behind after reading radio-frequency (RF) tag N minute of setting radio-frequency card reader, if so vehicle is when breaking down in this region, street lamp more than N minute after or can automatic distinguishing, will extremely be unfavorable for maintenance and the emergency of human pilot at night.
In addition, current domestic radar velocity measurement is all that antijamming capability is poor based on Doppler's principle, and following interference source (what comprise nature existence is what cause with people) all can cause radar meter error in reading or performance to reduce.
1, landform; Radar wave through most of solid-state object, can not comprise leaf.Glass also can reflected radar ripple, and therefore when radar is launched by cruiser glass, measuring distance can shorten.
2, rain; Rain can absorb and disperse radar signal, and this will cause the shortening of measuring distance, and the velocity readings simultaneously likely obtained is the speed of raindrop.
3, electronic noise; Electronic noise interference source has neon light signal, radio wave signal, power lead, transformer etc.These interference will make measuring distance shorten, and cause error in reading.After these interference are detected, radar will show " RFI ", and reading will no longer show simultaneously.
4, automotive ignition noise; The electronic system of a very large automobile of noise will cause the fluctuation of service of radar.
5, fan noise; When radar is launched in cruiser, fan noise is the problem that modal radar Doppler runs into.Have sub-fraction radar wave by glass-reflected in car, they will capture the noise of fan, thus produce mistake when making radargrammetry.
6, angular error; Radar Doppler only with target carriage direction on one wire time just can accurately measure.If there is certain angle during measurement, there will be angular error, display speed will be lower than actual speed.Angular error and angle remaining profound proportional.
7, from the interference of radio transition equipment; Near stronger radio transmitter also may have an impact to the measurement of radar.Then represent as radar asorbing paint " RFI " and interference detected.Now, any speed is no longer shown to prevent the reading of mistake.Interference source may be the vehicular radio on this car, or neighbouring transmitter, or illegal radio interference device.
As can be seen here, on existing road, velocity radar uses and there is error, truly cannot reflect the speed of vehicle, and the existing mode that tests the speed cannot keep fixing speed by active warning human pilot when overspeed of vehicle, avoids the generation of overspeed situation.
