Described smart jack is the other charger for electric bicycle of examination automatically, P2 is socket L, N, testing circuit is by resistance R 6, dpdt relay K1, diode D6, resistance R 13, photoelectrical coupler O2, resistance R 14 forms, K1 is dpdt relay, charger for electric bicycle L when socket idle condition, N is by resistance R 6, the normally closed node of dpdt relay K1, diode D6, receive photoelectrical coupler O2 input by resistance R 13 current limlitings, while not having charger to insert, in photoelectrical coupler O2, light-emitting diodes does not have electric current to pass through, in photoelectrical coupler O2, phototriode is without On current, NET2 node voltage is 5V, charger L in the time having charger to insert, between N, there is certain resistance, photoelectrical coupler O2 light-emitting diodes is luminous, photosensitive three pipes have certain On current, NET2 node voltage is <5V, NET2 is input to Chip Microcomputer A/D port, single-chip microcomputer detect voltage change be judged as charger insert.
Real-Time Monitoring charging current in charging process, described testing circuit is by D.C mutual-inductor T2, diode D5, diode D7, diode D8, diode D9, E4, capacitor C 8, resistance R 8, diode D11 composition, T2 is D.C mutual-inductor, charging process electric current passes through instrument transformer, instrument transformer output 0-5V alternating current, by diode D5, diode D7, diode D8, diode D9 rectification, E4 and C8 filtering, signal is by resistance R 8, diode D11 carries out data acquisition to Chip Microcomputer A/D port, single-chip microcomputer judges that storage battery is full of or is dialled by mistake image data analysis.
Described power-off re-powers the state before rear recovery power-off, and system master RCU adopts the single-chip microcomputer real time record current state with EEPROM;
Between described main control system and smart jack, form a local area network (LAN) by RS485, stored value card returns to money and can return at any socket and main frame.
Compared with prior art, the beneficial effects of the utility model are:
1, stop other equipment and use, such as: electric rice cooker, hair-dryer, electric furnace, these powerful devices of thermos all cannot use.
2, system detects in real time to electric car charger, and battery is full of stops power supply, and stops charging; Effectively avoid overcharging and bring battery explosion, the fault such as components and parts heatings is on fire, without relying on charger self configuration, if electric power exceedes electric motor car charge power, system is stopped power supply automatically.
3, possess preventing fraudulent use of electricity function, between owner's charge period, if there is people that charger is pulled out and changes oneself into, now this socket will power-off, the behavior of power stealing cannot be succeeded, and original owner's the power-cut time that is stuck in stops charging automatically.
Brief description of the drawings
Fig. 1 is system circuit diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated.
Between main control system and smart jack, be connected by RS485, the real time reaction of smart jack state is to main control system, in main control system liquid crystal display screen display, owner by display screen very fast can see the state that each socket is current, facilitate owner to find fast idle socket.
When smart jack idle condition, charger for electric bicycle L when charger for electric bicycle inserts, between N, there is certain resistance, as shown in figure mono-, O2 light-emitting diodes is luminous, photosensitive three pipes have certain On current, NET2 node voltage is <5V, NET2 is input to Chip Microcomputer A/D port, single-chip microcomputer detect voltage change be judged as charger insert, electric bicycle charging current is passed through instrument transformer, instrument transformer output 0-5V alternating current, pass through D5, D7, D8, D9 rectification, E4, C8 filtering, passing through R8, D11 carries out real-time data acquisition by Chip Microcomputer A/D port, by the analysis of data being judged to whether battery of electric bicycle is full of, battery of electric bicycle is full of automatic cut-out light source of charger.
