Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, further detailed description is done to the power supply anti-theft device in the present invention.
In the drawings, LED 1, reset switch button 2, contactless contactor 3, current sensor 4, power module 5, and MCU main control module 6, LED state indicating module 7, reset switch 8, socket 9, circuit breaker 10
See Fig. 1, Fig. 2 and Fig. 4, a kind of power supply anti-theft device, comprise the power module 5 of input termination civil power, low potential source is provided for giving MCU main control module, wherein: also comprise reset switch button 2, with the contactless contactor 3 for being arranged on power output end rear to be protected, current sensor 4, and MCU main control module 6, LED state indicating module 7, reset switch 8, described MCU main control module 6 receives the signal that process comes from current sensor 4, and controls the action of LED state indicating module 7 and contactless contactor 3; Described LED state indicating module 7 contains several for showing the LED 1 of current Car Burglar Alarm status; Described contactless contactor 3, current inductor 4, LED state indicating module 7, power module 5 and reset switch 8 are corresponding with MCU main control module 6 to be electrically connected.
Described LED 1 is red, green instruction color.
Described LED 1 has two.
Be connected with a socket 9 at described power output end to be protected, described socket 9 has 2 meters long at least with the electric wire of power output end.
As shown in Figure 3, AC220V civil power is by indoor circuit breaker 10(or be with earth leakage protective circuit breaker) access power supply anti-theft device input end, power supply anti-theft device mouth connects outdoor charging socket.Power supply anti-theft device is arranged on indoor circuit breaker 10 side, facilitates personnel to check the LED light of power supply anti-theft device and the position of operation reset button.Ground wire without power supply anti-theft device, directly can access socket.
Power supply anti-theft device principle of work: as shown in Figure 2, power supply anti-theft device input end is AC220V civil power, and through a contactless contactor, an electric current induction coil, mouth is similarly AC220V power supply.Internal piloting is controlled by MCU, and power module provides AC220V to turn the power supply of DC5V.MCU amplifies driving contactless coil through signal, control output end AC220V power connection or disconnection.Current sensor detects the electric current of AC220V circuit by mutual inductor.Reset switch is to MCU input switch signal (short by and long by).MCU drives two dual-colored LED lamps, when power supply anti-theft device supply regular power, if current sensor detects to reconnect after load disconnects suddenly or load transients changes, then system judges there is people at robber's electricity, MCU control contactor coil disconnects AC220V circuit, simultaneously two LED display red alarm.Again press reset button, AC220V circuit connected by MCU control contactor coil, recovers supply regular power, and two LED show green supply regular power (as shown in the table) simultaneously.If power supply anti-theft device two LED display yellow alarm, be then that System self-test does not pass through or generation systems fault, length can be removed by reset button.If two LED displays are green, then illustrate and restart successfully, system supply regular power; If two LED still show yellow, then illustrate that power supply anti-theft device damages, needs depot repair.
In addition, according to the type of battery, capacity, charge curve, power supply anti-theft device can judge battery has filled how many electricity, can be seen by indoor power supply Car Burglar Alarm LED, does not need to go to see to outdoor charger.This function does not need to be connected extra signal with charger, can compatibility most charger on the market.Realize the charge curve according to battery when principle is battery charger charging, different in different capacity stage charging currents, this also means that the load current of AC220V is different, there is a corresponding relation with the capacity of battery, calculate battery by the large I of AC220V load current and filled percent how many electricity.Then shown by LED, as shown in the table, the flicker of two green LED lamp same frequencys represents charge volume and is less than 80%, and have a Chang Liang, a flicker represents that charge volume is between 80-100%, two green Chang Liang represent charge volume and reach 100%.If can not identify that charger type (namely the type of power supply anti-theft device and charger is not mated) or load are not chargers, then cannot judge filled how many electricity, two green LED lamp alternately flickers, but power supply anti-theft device still normally can work.
