Description of the drawings
Fig. 1 is a kind of intelligent protection device embodiment schematic diagram of the present invention；
Fig. 2 is a kind of intelligent protection device ON-OFF control circuit embodiment schematic diagram of the present invention.
Specific implementation mode
The present invention is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
Shown in Fig. 1, Fig. 2, in the following embodiments, intelligent protection device of the present invention, including：
ON-OFF control circuit and two NMOS power switch tubes；The ON-OFF control circuit is by high pressure generation module, rectification module,
Voltage stabilizing module, voltage detection module, current detection module, surge protection module, temperature control modules and digital control module structure
At.
Ac input end and ac output end are all the alternating voltages of 220V；NM1 is managed and NM2 pipes, as power switch tube,
All it is NMOS tube, grid high voltage conduction, grid no-voltage is shut off.
The input terminal of ON-OFF control circuit is ac input end, and output end controls the grid of NM1 and NM2.
Due to being that NMOS tube is used as switch, the switch is closed, then grid voltage is 0, if made
Switch conduction is obtained, then grid just needs a high voltage to go to be connected, such as 220V,
Therefore a circuit for producing high voltage is needed to go to generate a high pressure, the conducting state for controlling switch.
Rectification circuit converts alternating voltage to DC voltage, supply switch control pipe internal work.
Voltage stabilizing module be exactly worked required supply voltage, such as 1.8V according to DC voltage generation circuit, or
3.3V or 5V powers for internal circuit modules.
Voltage detection module, detection input voltage is 220V, can be preset as needed, such as positive and negative 10%
Deviation be normal, then alarm signal is just sent to by the voltage detected less than 200V or just alarming higher than 240V
Digital control circuit,
After digital control circuit receives alarm signal, circuit for producing high voltage is just controlled, closes the output of circuit for producing high voltage, in this way
Entire circuit is at closed state, condenser after protection.
Current detection module detects electric current, when the electric current flowed through is excessive, just alarms, automatic cut-off switch.
Temperature detecting module detects Current Temperatures, and when temperature is excessively high, for example temperature is to 70 °, with regard to automatic cut-off switch,
Surge protection module, the abnormal causes such as detection thunder and lightning cause voltage to rise the case where burning out follow-up household electrical appliances rapidly.Once inspection
Measure abnormal voltage, inside is released unlatching, while also output signal goes to turn off the switch the subsequent equipment of protection.The module can
Duplicate protection is played, is on the one hand that inside is released, still further aspect is according to the voltage high pressure of inspection to choose whether to close
Switch.
Although the present invention is illustrated using specific embodiment, the present invention's is not intended to limit to the explanation of embodiment
Range.One skilled in the art is by reference to explanation of the invention, without departing substantially from the spirit and scope of the present invention
In the case of, it is easy to carry out various modifications or embodiment can be combined.
