Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of smart jack, as shown in Figure 1: comprise controlled jack 1, controlled jack 1 is provided with relay 2, and relay 2 links to each other with micro-control unit MCU, and micro-control unit MCU also links to each other with status display circuit 4 with load detecting circuit 3.Described micro-control unit MCU also links to each other with study button 8.The power end of described relay 2 links to each other with resistance-capacitance depressurization circuit 6, and is provided with current rectifying and wave filtering circuit 5 between the two, and the input of resistance-capacitance depressurization circuit 6 links to each other with mains supply.Describedly link to each other with resistance-capacitance depressurization circuit 6, be provided with current rectifying and wave filtering circuit 5 and voltage stabilizing chip 7 from resistance-capacitance depressurization circuit 6 to micro-control unit MCU successively with micro-control unit MCU.Described relay 2 links to each other with micro-control unit MCU by triode.Described load detecting circuit 3 comprises current transformer and operational amplification circuit.Described resistance-capacitance depressurization circuit 6 comprises the decompression capacitor and the current-limiting resistance of series connection, also is parallel with discharge resistance on the decompression capacitor.Described current rectifying and wave filtering circuit 5 comprises rectifier bridge and filter capacitor.
Specific embodiment 1.Figure 2 shows that the schematic diagram of power supply relevant portion.
AC power is from L (live wire) and N (zero line) input, for the damage of the impacting with high pressure that prevents to power on first and produced when fast insert-pull attaching plug or attaching plug loose contact to rectifier bridge, we connect current-limiting resistance in circuit, the current-limiting resistance resistance can not be too little, can not be too big, the too little impulse current of resistance is big, and the too big entire circuit power consumption of resistance increases.Current-limiting resistance will be selected high-power oxide-film resistance or golden film resistance, can not adopt the resistance of paster encapsulation.
Decompression capacitor in the resistance-capacitance depressurization part, consider the fluctuation of line voltage and mains frequency, will consider during design to use under the worst situation can not occur unusual and damage, so reserve certain surplus, but in order to reduce Overall Power Consumption, surplus can not be reserved excessive, and the big more circuit of electric capacity is dangerous more simultaneously.Discharge resistance in the resistance-capacitance depressurization circuit, can prevent when fast insert-pull attaching plug or attaching plug loose contact, touch human body after residual voltage on the decompression capacitor and line voltage stack back form impacting with high pressure and extract attaching plug subsequent device personnel are damaged.After the decompression capacitor step-down, be alternating voltage still, need rectification circuit to carry out rectification.
Pulsating direct current behind over commutation needs to be converted to direct voltage stably through filtering.Filtered direct voltage instability need be carried out voltage stabilizing, and the voltage stabilizing value of voltage-stabiliser tube need be selected according to the load required voltage.
When the electric equipment stand-by power consumption is higher than the control gate limit value of our setting, we will detect less than the standby of electric equipment and off-mode, promptly can't disconnect the peripheral hardware power supply that is connected to controlled jack, in order to carry out the power on/off control of controlled jack according to different electric equipments, we have designed to press to the study of electric equipment stand-by power consumption or control gate limit value and memory function and by the user and button is set has started this study and memory function, so we have added the button input.
As shown in Figure 3, one key K1 is used to start study and the memory operation to the electric equipment stand-by power consumption.When the user pushes button K1 when surpassing 3 seconds, MCU will detect this push button signalling by the I/O mouth of push button signalling input, and start study and memory operation, and the threshold value of electric equipment power consumption correspondence writes FLASH with this moment, and power down is not lost.
Status display circuit 4: after system powers on, when if the power unit of system is in normal operating conditions, the LED that is connected with supply voltage will light, and in order to show the power on/off state of controlled jack, MCU is used to show the LED of controlled jack power on/off state by the control of I/O mouth.During study button in pressing above-mentioned button partial design, system is in study and remember condition, shows that the LED of controlled jack power on/off state will glimmer; When study and after memory operation finishes, this LED will stop flicker, the power on/off state of the current controlled jack of steady display, and when the peripheral hardware power supply on electric equipment and the controlled jack broke, light-emitting diode extinguished, and the expression system is in non operating state.
The structure of controlled jack 1 and relay 2 is as shown in Figure 4:
After MCU detects the state of electric equipment, need control the power on/off of controlled jack.In the utility model to the control of controlled jack power on/off, be that adhesive by control relay realizes, utilize normally closed, the normally opened contact of relay to carry out the circuit switching, the operating voltage of relay is higher, therefore, change through overdrive circuit from the signal demand of MCU output, make the driving voltage of output can adapt to the requirement of relay, and what use in the design is subminiature relay, operating current is less, little to the power supply influence, do not need to add buffer circuit.
The voltage at relay coil two ends, by selected relay model decision, the circuit design principle and the supply voltage part that obtain this voltage are similar, just owing to the required electric current of relay is bigger, so the resistance-capacitance depressurization parameter is selected difference.
Controlled jack connecting line is connected the normally opened contact of relay, and when detecting electric equipment and be in different conditions, MCU will export varying level on corresponding I/O, the control relay adhesive, thus control controlled jack power supply.
The circuit of each part mentioned above except that power unit, the hardware foundation that carries out various detections, control operation are to the electric equipment status detection, i.e. the test section circuit of this part.
For the electric equipment that is operated in the different power consumption under the same civil power, corresponding electric current difference, therefore to the identification and the differentiation of different electric equipments, can promptly can realize the circuit signal of different electric equipments is extracted by its corresponding current signal is detected realization by current transformer.Form certain voltage signal through the current signal after this current transformer conversion at the load two ends, be input to MCU for convenience and detect, and this voltage signal is handled by amplifier relevant portion circuit.
Owing to do not have negative voltage in the circuit, if this voltage signal is directly inputted to operational amplifier to be handled, to have to the positive axis of voltage signal, if handle such output signal, need carry out zero crossing to this signal detects, like this hardware and software is had relatively high expectations, be inconvenient to handle, so on hardware, we are in the circuit of amplifier processing section, by adopting certain circuit to connect, be input to MCU after the voltage signal in whole cycle of electric equipment correspondence amplified, adopt on the software and ask root mean square method to detect electric equipment.
After the relevant treatment through current transformer and operational amplifier, signal is input to main control MCU, and MCU carries out ADC to the electric equipment state and detects.
