Safety intelligence socketThe invention relates to socket, the particularly invention of safety intelligence socket, there are an intelligent apparatus and socket leader in this socket inside, and the power on/off of this socket leader is controlled by above-mentioned intelligent apparatus.
In order to ensure child's safety, father and mother's often that some are dangerous electrical equipment of going out resembles electric iron, electric rice cookers etc. are covered up or enjoin child not touch, so as to avoid an accident, and only allow them recreational to resemble electronic organ with the little electrical equipment of danger with those, recorder etc., also usually warn the electrical equipment that the passenger is equipped with in the guest room in same hotel, the not random electrical equipment that uses the passenger to carry, to avoid fire, these work in the past are just by oral or literal is warned, and the bad control of its performance, so usually because of electricity consumption some accidents take place accidentally.
The objective of the invention is to provide a kind of can allow those others arbitrarily used electrical equipment to memorize for other people use according to owner's suggestion, and those owners do not allow others' safety intelligence socket that can't use of electrical equipment of random use, and it can prevent the accident that causes accidentally because of electricity consumption effectively.
The object of the present invention is achieved like this: the power on/off of removing to control the socket leader with an intelligent apparatus, this intelligent apparatus by status switch, Single Chip Microcomputer (SCM) system, D/A converting circuit, analog to digital conversion circuit, relay and sense switch form, status switch switches by key, has three states: study, work and energising by force.Closure when sense switch inserts at power consumption equipment disconnects when power consumption equipment is pulled up.When status switch being switched to learning state with key, Single Chip Microcomputer (SCM) system is at first inquired about the sense switch judgement and is had or not power consumption equipment to plug, have then and give power consumption equipment by D/A converting circuit output drive signal, receive the response of this power consumption equipment simultaneously by analog to digital conversion circuit, the model that draws this power consumption equipment deposits internal memory in, continue to look into the state of status switch and sense switch then, do not have power consumption equipment to plug and also continue inquiry.When status switch switches to operating state, Single Chip Microcomputer (SCM) system judges that earlier the sense switch closure does not have, closed then draw the model of this power consumption equipment by above-mentioned same method, but do not preserve, but the model of remembering in the judgement internal memory has or not the identical person of model herewith, has to illustrate that then this power consumption equipment learnt can control relay make this socket energising, does not have identical model, illustrate that then this power consumption equipment do not learn, do not give energising.When the power consumption equipment that is in "on" position was pulled up, sense switch disconnected, and the notice Single Chip Microcomputer (SCM) system is cut off the power supply of this socket.The state of single-chip microcomputer continuous-query status switch and sense switch.Switch to the socket that Single Chip Microcomputer (SCM) system control relay when switching on by force will insert power consumption equipment as status switch and switched on by force, and do not judged comparison.
The present invention makes the single-socket formula and many female types can.
The present invention is because only give the power consumption equipment of learning power supply, this has just guaranteed that staff false touch socket leader can not suffer yet, this has brought safety for active children, and can avoid the passenger in children or the hotel to use dangerous electrical equipment without authorization, in case meet accident, and owner can connect any power consumption equipment by force by key.This safety intelligence socket plays a very good protection for family, hotel and children's safety.
Accompanying drawing has been described one embodiment of the present of invention, the situation of single channel socket.
Accompanying drawing 1 is physical circuit figure of the present invention, and+E is the memory stand-by power supply, can preserve the memory content of internal memory after the power down of this socket, LED1For power consumption equipment is not familiar with indication, LED2For having learnt indication, LED3For useful equipment inserts indication, LED4Be learning state indication, LED5Be energising indication by force, LED4And LED5It when all not working the operating state sign.K is status switch [1-1], dials to the left side to be "on" position by force, and the centre is an operating state, and the right is a learning state, 8751 and 74LS139 formation Single Chip Microcomputer (SCM) system [1-2], and DA0832, F1-2, and R1-4Constitute D/A converting circuit [1-3], AD0804, F3-4, R5-11, C1-3And D2-3Constitute analog to digital conversion circuit [1-4], J constitutes relay [1-5], A2Sense switch [1-6] for socket.Status switch [1-1], Single Chip Microcomputer (SCM) system [1-2], D/A converting circuit [1-3], analog to digital conversion circuit [1-4], relay [1-5] and sense switch [1-6] constitute intelligent apparatus (1), and AB is socket leader (2), and both form safety intelligence socket.A1Reset button for Single Chip Microcomputer (SCM) system [1-2].
Energized, Single Chip Microcomputer (SCM) system [1-2] continuous-query status switch K and sense switch A2State, A2Not closedly continue to look into.When being learning state as the closed query State K switch of A2, relay J discharges, power consumption equipment is connected with the digital-to-analogue analog to digital conversion circuit by relay contact, Single Chip Microcomputer (SCM) system [1-2] sends pumping signal pseudo-random binary M sequence for D/A converting circuit [1-3], accept the response of power consumption equipment simultaneously by analog to digital conversion circuit [1-4], draw the model of power consumption equipment and memorize by the System Discrimination algorithm, the bright expression of LED2 has been learnt.As status switch is operating state, the same earlier power consumption equipment on the socket identification, and the model that draws power consumption equipment compares with the model of remembering in the internal memory, have identical person that this power consumption equipment understanding is described, energized does not have identical person, then disconnect power supply, indicator light LED1Bright, illustrate that this equipment is not familiar with, when the power consumption equipment of connection was pulled up, relay J also discharged simultaneously, and socket leader (2) cuts off the power supply again.As status switch K during, connect the power supply that inserts with the socket leader of equipment, and do not discerning and comparing for "on" position by force.
