Abstract
A remotely or manually controlled electric appliance state detector features that a conducting wire with insulating surface is wound on a magnetic ring and one of the power supply lines for electric appliance passes through the magnetic ring. When a current flows through said power supply line, an induced voltage is output from said winding. Measuring the variation of said induced voltage can judge the current state of electric appliance.
Description
The present invention relates to a kind of household electrical appliance
The remote control of electrical equipment can realize with a lot of modes, such as radio, microwave, infrared ray or the like, but inconvenient on the contrary sometimes with remote control, such as: switch electrical equipment at one's side, and telepilot is not at one's side, will go for the switch of remote control, all can operate, could really bring convenience like this to the user so preferably can accomplish remote control and manual control.And to accomplish this point, key is to want to understand very reliable and exactly the immediate status of electrical equipment, because the use of manual switch, the state of electrical equipment can change at any time, the immediate status of electrical equipment be can not know definitely, remote control and the manual purpose of using control apparatus of mixing just can't be realized.
The objective of the invention is to provide a kind of remote control and manual electrical equipment state detector that uses that mixes of being adapted to, it can detect electrical equipment exactly at residing state all the time, it can come out detected situation with clear and definite signal indication, for the foundation that remote controller is made comparisons and differentiated, reach remote control and the manual purpose of using control apparatus of mixing.
The present invention is achieved in that a kind of remote control and manual electrical equipment state detector that uses that mixes of being adapted to, lead by magnetic material and appearance insulation constitutes, it is characterized in that: a hole is arranged on the magnetic material, and the lead of appearance insulation passes on magnetic material from the hole of magnetic material; There is one from the hole of magnetic material, to pass in the power lead of the electrical equipment that detects; When power lead has electric current to pass through, can produce the induced potential that can measure in the lead of appearance insulation.The hole of magnetic material is a closed.The diameter of the lead of appearance insulation is littler than the diameter of the power lead that passes from the hole of magnetic material.The number of times that the lead of appearance insulation passes from the hole of magnetic material passes often from the hole of magnetic material than the power lead of institute electricity measurer.The number of times that the power lead of institute's electricity measurer passes from the hole of magnetic material is no less than once.
The present invention utilizes principle induced electricity to detect the state whether electrical equipment is in work, even there is very little electric current to pass through, also will inevitably produce induced current, and there is not induced current when not having electric current to pass through, here we will detect is to have and do not have, and by measuring the variation of coil both end voltage, just is easy to obtain conclusion, and the accuracy of measuring is very high, and reliability is very strong.Because the voltage volitional check of magnetically saturated reason induced current is about 2 volts, so security is secure.
Concrete structure of the present invention is provided by following examples.
Fig. 1 is a structural representation.
Fig. 2 uses synoptic diagram.
The present invention will be described in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the lead (2) of appearance insulation passes hole (3) on magnetic material (1), form an inductive coil (5), (4) be the extension line of inductive coil (5) head and tail, (6) be the power lead of detected electrical equipment D, power lead (6) passes from hole (3), and the number of times that passes can be repeatedly, also can be once, determine as required.
When power lead (6) did not have electric current to pass through, inductive coil did not have induction current in (5), and it is 0 that the extension line at two ends (4) is gone up voltage.
With reference to Fig. 2, C is a detecting device of the present invention, and (10) are controllers, and (7) are the imports of guidance command on the controller, and (8) are and the mouth of getting in touch of detector C of the present invention, and (9) are the mouths of getting in touch of controller (10) and relay J.
Relay J and manual switch SK are the ganged switches of 1*2, and their a point is connected with a point, and the b point is connected with the b point,
After tested electrical equipment D opens, must there be electric current from power lead (6), to flow through, there is electric current from power lead (6), to flow through and need only one, must produces induced potential in the inductive coil (5), on the extension line (4) of inductive coil (5), the voltage that can measure must be arranged.Therefore, on extension line (4), measure voltage, just judge it is the state that is in unlatching, go up at extension line (4) and measure, just judge to be in closing state by electricity measurer D less than voltage by electricity measurer D.The variation of this voltage gives controller (10) when handling guidance command, and a tangible foundation has been arranged.
For example: D1 is in closing state among the figure, does not have electric current to flow through in the power lead, does not also detect voltage on the C1, because controller (10) obtains is the signal that does not have voltage on the C1, so just judge that D1 is in closing state.
D2 is the state that is in unlatching among the figure, has electric current to pass through in the power lead certainly, also has voltage to measure on the C2 certainly, and what controller (10) obtained is the signal that voltage is arranged on the C2, therefore just judges that D2 is the state that is in unlatching.
Now, the order that controller (10) obtains opening D1 from import (7), controller (10) just goes to inquire about whether voltage is arranged on the C1, inquiry knows there is not voltage, and D1 is in closed condition, just changes a upper/lower positions by (9) order J1, change a road and connect, connect for the b road, electrical equipment D1 has just opened.This is once to come fill order with the relay J action.
If, the order that controller (10) obtains opening D2 from import (7), controller knows on the detector C 2 that D2 connects that by inquiry voltage is arranged, and therefore judges that D2 has been in the state of unlatching, needn't change the position of J2, carry out the order of opening D2 to be failure to actuate.
So as long as detector C has been arranged, no matter manual switch SK action several times, no matter what state electrical equipment D was in just now, controller can be judged the current accurate status of electrical equipment D, and according to this current state, accurately carries out the order of any remote control at once.
