For setting the time of road lamp power supply switch, variable reactor is made for adjusting road lamp power supply voltage swing, bypass output circuit
It is stand-by circuit for being street lamp power supply, road lamp power supply.
As shown in Fig. 2, acoustic control conditioning circuit includes microphone, operational amplifier, A/D converter, external voice signal is passed
After entering microphone, the weak audio signal of input is converted to by voltage signal by operational amplifier, this voltage signal is again by A/D
Converter is converted into digital signal and is sent to PLC controller, so that PLC controller is handled according to the digital signal of input.
It is issued by the voice signal of system acquisition by pedestrian on road and vehicle, therefore high sensitivity, non-linear distortion need to be selected
Microphone small, Hz-KHz is wide.This system selects acquisition device of the condenser microphone as road surface acoustic information, the sensing
Device is suitable for the pickup of high quality.
The light control sensor of light-operated conditioning circuit uses phototriode in this system, because phototriode is in addition to having
Photodiode can convert optical signals into outside the function of electric signal, can also amplify to electric signal.
As shown in figure 3, the voltage signal that the voltage detecting circuit of this system will test is sent to PLC controller, PLC control
Device processed according to circumstances sends a control signal to variable reactor and is adjusted voltage, the design principle of variable reactor be by
Then all making alive in the primary and secondary side of transformer adjusts the voltage of transformer secondary, so that main flux changes, thus
It realizes that the impedance of transformer primary avris changes, the voltage of primary side is adjusted finally by the variation of impedance.
If with UAFor A phase voltage virtual value, ULFor transformer primary avris voltage, URFor lamp voltage, then have: UA=UL+UR,
If with U 'LFor the induced voltage that primary current is generated in primary side, U 'L2For the voltage that secondary current is generated in primary side, U "LFor primary side
The induced voltage that electric current generates on secondary side, U "L2For the voltage that secondary current generates on secondary side, BmFor magnetic induction intensity, N is circle
Number, s is sectional area.So, following relational expression will be present in system:
UL=U 'L+U′L2
U′L2=4.44fN1BmS
UL2=U "L+U″L2
