Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
A kind of street lamp data acquisition device of the present invention, the street lamp data acquisition device include front end signal sampling unit,
Data processing unit and signal output unit, its main feature is that：The front end signal sampling unit input terminal is electric with power supply respectively
PressureSensor output, zero curve and ground wire voltage (drain voltage)Sensor output, phase line current i1Sensor output

Go out unit to be connected.The signal output unit includes display unit, wireless network communication unit and ethernet communication unit.
The present invention can realize that dynamic constantly detects voltage, electric current, line drop, leakage current, electrical leakage voltage.Electric leakage electricity
The change of pressure, all data of ground resistance upload in time.
Above supply voltageZero curve and ground wire voltage (drain voltage)Phase line current i1With neutral line current i2Electricity passes through
Enter data processing unit, after processing, signal output unit display processing result after A/D conversions and pass through handling result logical
Interrogate unit transmission host computer processing.
The present invention street lamp fault judge method be：
1. drain voltage directly detects；Pressure difference between zero curve and ground wire
2. leakage current i=i1‐i2:Wherein i1For phase line current, i2For neutral line current, when phase line Leaked Current of Line to Ground occurs.Due to
Electricity consumption switch contacts are exposed to wait technological reason, air themperature increasing or directly water inlet to produce leakage current with ground wire electric discharge, then
Phase line and zero curve produce current differential, are leakage current.Ground resistance becomes larger, ground leakage resistance diminish produce zero earth potential it is poor
(influence personal safety) necessary fast slowdown monitoring, and geodetic resistance and change can be calculated.
Measurement result based on load attribute data (judging phase difference Fig. 6, Fig. 7 by zero-crossing comparator)：
It can judge to draw (time difference (Fig. 8) of phase current IF and phase voltage VF rising edges) by phase：
1st, it is resistance inductive load during normal condition.Electric current IF lags behind voltage VF1-2ms, if capacitance open circuit lags
Between be greater than 2.5ms.
If the 2, fluorescent tube is opened a way, the electric current IF leading voltage VF times are more than 2.5ms (having compensating electric capacity).
If the 3rd, fluorescent tube short circuit, electric current is more than normal value and the electric current IF lagging voltage VF times are greater than 2.5ms
4th, lamp does not work, and detects that trigger pulse (100HZ) trigger is normal, otherwise trigger failure.

>=30mA or part-loading goods >=30V) then upload leakage-current alarm.
For high-pressure sodium lamp after the triggering of thousands of volt electromotive force, gas collisions produce electric current, are one negative as shown on the left of figure Vt
Characteristic is hindered, as time went on, light tube electric voltage increases the lamp current very big (or even can regard instantaneous short-circuit as) of startup, lamp current
Reduction progressively reaches stable state (near Vt, It).A linear resistance can be regarded during normal operation as, as shown on the right side of figure Vt points.Electricity
It is with larger current increment to press increment.
Light-off breakdown judge is drawn according to the measurement of the negative resistance charactertistic (Fig. 3) and load attribute data of gas-discharge lamp.
One, sodium vapor lamps (containing Metal halogen lamp) failure：
(1) i is detected1There is the trigger pulse of power frequency, and
A) it is in negative value (having compensating electric capacity) by line power factor.
B) discontinuously only there is (uncompensated capacitance) in pulse to i1
(2) trigger damages：Without trigger pulse
(3) lamp short circuit, the specified starting currents of i1 ＞, and i1 does not change, power factor is low, and unchanged.
(4) ballast turn-to-turn short circuit, triggering line power are more than normal value, and i 1 is more than normal value
(5) capacitance open circuit, lamp is working properly, but power factor is less than normal value.
(6) fluorescent tube aging, detects lamp power cycle.(triggering, start, extinguish.)
2nd, LED and other electronic loads judge (Fig. 4, Fig. 5)：
After the amplitude and phase-detection of i1, the values of power factor PF ＞ 0.95 be normal compensatory, when i1 is minimum power P=0,
Lamp failure extinguishes.PF ＜ 0.8 after detection, and i1 is discontinuous, conducting phase was less than for 1/2 cycle, both can determine whether as general nonlinearity
Electronic load, need to add compensation (including lamp box etc.).
