Description
Technical field
The utility model relates to a kind of attaching plug, is specifically related to a kind of attaching plug that opens and closes automatically.
Background technology
The kind of the electric equipment in the family is more and more at present, because people's ignorance, there are a lot of electric equipments no the time, still to be in unmanned open state, or being in holding state for a long time, these two states all can cause waste to the energy, stand-by power consumption particularly, a lot of electrical equipment are in holding state for a long time, not only waste energy, and also also unfavorable to electrical equipment itself.
The utility model content
The utility model provides a kind of attaching plug that opens and closes automatically, and purpose is in order to allow electric equipment change thorough closed condition over to from holding state automatically; When starting electric equipment, the utility model equipment can also change "on" position over to automatically by off-position.
For achieving the above object, the utility model adopts following scheme:
A kind of attaching plug that opens and closes automatically, form by attaching plug and the little power consumption intelligent controller that is integrated in attaching plug inside, it is characterized in that, described little power consumption intelligent controller comprises single-chip microcomputer, current sensor, analog to digital converter, relay and AC/DC, described relay links to each other with live wire with the zero line of attaching plug, described Hall type current sensor is connected on the live wire of attaching plug, the power input of described AC/DC links to each other with live wire with the zero line of attaching plug, its output is parallel with single-chip microcomputer and analog to digital converter, and the I/O pin of described single-chip microcomputer is connected with the control power input of relay.
Preferably, described current sensor is the Hall type current sensor.
Preferably, described relay is a double-pole single-throw (D.P.S.T.) type relay.
Preferably, described current sensor is connected the arbitrary end on the live wire of two ends on the relay.
Preferably, described AC/DC is connected on the live wire and zero line of live wire input in the relay.
After adopting such scheme, the utility model plug can make electric equipment change thorough closed condition over to from holding state automatically, reduces the waste of electric resources.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, a kind of attaching plug that opens and closes automatically, form by attaching plug and the little power consumption intelligent controller that is integrated in attaching plug inside, little power consumption intelligent controller comprises single-chip microcomputer 1, current sensor 5, analog to digital converter 4, relay 3 and AC/DC2, relay 3 links to each other with live wire 6 with zero line 7 in the attaching plug, zero line 7 is connected with the power line of electric equipment with contact 8 on the live wire 6, zero line 7 is connected with external cord with contact 9 on the live wire 6, relay 3 is a double-pole single-throw (D.P.S.T.) type relay, and current sensor 5 is the Hall type current sensor; Current sensor 5 is installed in the arbitrary end on the live wire of two ends on the relay 3 in the attaching plug; The power input of AC/DC2 links to each other with live wire 6 with the zero line of attaching plug 7, its output is in parallel with single-chip microcomputer 1 and analog to digital converter 4, for AC/DC2 is remained under the state of work constantly, give single-chip microcomputer 1 and analog to digital converter 4 power supplies, AC/DC2 should be connected on the live wire 6 and zero line 7 of live wire input in the relay 3.The I/O pin of single-chip microcomputer 1 is connected with the closure of relay 3 control power input.During the acquiescence energising, the I/O pin of single-chip microcomputer 1 is sent useful signal, makes zero line 7 and live wire 6 to be communicated relay 3 make contacts, allows electric equipment be in normal operating conditions.Because the power consumption of electric equipment when normal the use is tens watts, hectowatt or kilowatt, and the power consumption of electric equipment when standby is less than 5 watts, after current sensor 5 reads the electric equipment consumed current and it, convert voltage to, be transferred to analog to digital converter 4, convert digital signal to by analog to digital converter 4, send single-chip microcomputer 1 again to, after single-chip microcomputer 1 is converted to power consumption, as the power consumption when finding the electric equipment power consumed less than standby, then open the timer in the single-chip microcomputer 1, if in the time that timer is set, the power consumption of the electric equipment that single-chip microcomputer 1 detects all is the power consumption when being lower than the electric equipment standby, and then monolithic 1 machine is cancelled effective control signal of I/O pin, makes relay 3 break contacts, thoroughly cut off the power supply of electric equipment, single-chip microcomputer 1 also changes resting state over to.Otherwise if the power consumption of the power consumption that detects during greater than standby, monolithic 1 organizational security is held the output of effective control signal of I/O pin, makes relay 3 keep connecting, and normal power supply is given electric equipment.Disconnect at single-chip microcomputer 1 control relay 3, and after changing resting state over to, can wake up automatically once every 1 second, between awake period, again allow the I/O pin of single-chip microcomputer 1 export control signal temporarily, engage relay 3 four ten milliseconds (two civil power cycles) is to survey the electric equipment power consumed, if finding power consumption promotes, think that then this electric equipment is artificially opened once more, single-chip microcomputer 1 withdraws from resting state at once, allows the control signal of single-chip microcomputer 1 interior I/O pin keep output state, and latching relay 3 continues to connect, allow electric equipment normal electric work, begin the new machine testing for the treatment of simultaneously.
The utility model is not only applicable to attaching plug, also is applicable to the power supply power socket.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make other distortion or improvement, these all belong to protection range of the present utility model.
