Description
Technical field
The present invention relates to a kind of economize on electricity and exchange Doorbell Receiver.
Background technology
At present, exchange Doorbell Receiver and adopt the single capacitor reduction voltage circuit, power consumption is the same not big in the holding state of jingle bell and the doorbell jingle bell process.The actual needed useful power of circuit does not only account for the very little part of total power consumption during jingle bell; Therefore efficient is very low; Waste of energy is very big; And unnecessary electric energy is converted into heat energy makes the doorbell temperature rise bigger, and higher temperature can be accelerated the aging speed of electronic component, the serviceable life that shortens product and reduction reliability of products.
Summary of the invention
For overcome existing exchange the Doorbell Receiver power consumption big with the higher deficiency of temperature rise, the present invention provides a kind of stand-by power consumption and economize on electricity of reduction standby temperature rise can reduce jingle bell not automatically the time to exchange Doorbell Receiver.
The technical solution adopted for the present invention to solve the technical problems is: described Doorbell Receiver contains two capacity voltage dropping circuits, receiving circuit, control circuit and the doorbell music circuit that can between low power consumpting state and high power consumption state, switch.The work characteristics of Doorbell Receiver is: most times are in the not holding state of jingle bell, and only need very little power this moment, and having only the only a few time to be in need more high-power jingle bell state.And that capacity voltage dropping circuit has a capacitance is high-power more big more, and capacitance is the more little characteristics of miniwatt more.When Doorbell Receiver is in the holding state of jingle bell not; Capacity voltage dropping circuit switches to low power consumpting state; Capacity voltage dropping circuit switches to high power consumption state in the doorbell jingle bell process; Therefore both can reduce the power consumption under the holding state that doorbell is in jingle bell not as far as possible, and have in the time of can guaranteeing jingle bell again to have enough power.Because most times of Doorbell Receiver are in the not holding state of jingle bell, so power savings highly significant of the present invention, the receiver temperature rise is almost nil, when realizing economize on electricity, also reduces the crash rate of the product that is caused by temperature rise.

Embodiment
Theory diagram of the present invention is shown in accompanying drawing 1.The present invention is made up of receiving circuit, control circuit, doorbell music circuit and two capacity voltage dropping circuits that can between low power consumpting state and high power consumption state, switch.Receiving circuit receives the jingle bell control signal of being come by Channel Transmission, converts the digital signal that control circuit can be discerned to.Control circuit has three kinds of functions, and first kind of function be, the identification ringing signal, and second kind of function is the duty of switch dual capacity voltage dropping circuit between low power consumpting state and high power consumption state, the third function is to trigger doorbell music circuit sounding.After the controlled circuit triggers of doorbell music circuit, the output ringing signal drives loudspeaker and sends the tinkle of bells.Two capacity voltage dropping circuits that can between low power consumpting state and high power consumption state, switch are 220VAC or the input of other alternating voltages; Convert low-voltage dc voltage into; Supply receiving circuit, control circuit and doorbell music circuit to use; And can under the control of control circuit, switch high power consumption state and low power consumpting state.
In accompanying drawing 2 and accompanying drawing 3 illustrated embodiments, the actual required power of circuit equal that receiving circuit consumes the summation of power of power, power that control circuit consumes, power that doorbell music road consumes and capacity voltage dropping circuit loss.No matter jingle bell whether, the power of receiving circuit and control circuit consumption is constant, is about 1.4mW.During jingle bell, the power that the doorbell music circuit consumes is very big, reaches the hundreds of milliwatt, and not during jingle bell, the power of doorbell music circuit consumption is zero.When jingle bell not; If the power of capacity voltage dropping circuit is constant; The power of the overwhelming majority will be wasted on R1, rectifier bridge and the stabilivolt of capacity voltage dropping circuit; If reduce capacitance this moment the power of reduction voltage circuit is reduced, the power that is wasted on R1, rectifier bridge and the stabilivolt of capacity voltage dropping circuit will diminish, thereby the total power consumption of Doorbell Receiver also diminishes.Still promptly do not influence the operate as normal of Doorbell Receiver after the power reduction of assurance capacity voltage dropping circuit greater than the power of receiving circuit and control circuit consumption.
Two capacity voltage dropping circuits that can between low power consumpting state and high power consumption state, switch have two kinds of implementation methods.
First kind of capacity voltage dropping circuit is shown in capacity voltage dropping circuit part in the accompanying drawing 2, and wherein C1 is big electric capacity, and capacity is 1 μ F, and C2 is little electric capacity, and capacity is 0.047 μ F, and electromagnetic relay is with parallelly connected with little capacitor C 2 again after capacitor C 1 is connected greatly.When Doorbell Receiver was in the holding state of jingle bell not, the IOA1 output low level of single-chip microcomputer IC1 made electromagnetic relay K1 be in off-state, and form low-power capacity voltage dropping circuit by little capacitor C 2, rectifier bridge D1, stabilivolt D2 this moment.Since this moment doorbell not ring required power very little, the power that this low-power capacity voltage dropping circuit provides is enough greatly.After receiving ringing signal, the IOA1 of single-chip microcomputer IC1 output high level makes electromagnetic relay K1 conducting, and big capacitor C 1 satisfies the demand of doorbell music circuit to power with C2 parallel connection, this moment, the capacity voltage dropping circuit output power became big.After jingle bell finishes, the IOA1 of single-chip microcomputer IC1 output step-down, electromagnetic relay K1 breaks off, and circuit returns low power consumpting state.
Second kind of capacity voltage dropping circuit is shown in capacity voltage dropping circuit part in the accompanying drawing 3, and wherein C1 is big electric capacity, and capacity is 1 μ F, and C2 is little electric capacity, and capacity is 0.047 μ F.When Doorbell Receiver was in the holding state of jingle bell not, the IOA1 of single-chip microcomputer IC1 output high level made bidirectional triode thyristor Q1 be in off-state, and the electric current that flows through big capacitor C 1 this moment is zero.The input AC electric current flows to the rectifier bridge of being made up of diode D1, D2, D3 and D4 through too small capacitor C 2, clamped and and the electric capacity E1 filtering formation galvanic current pressure through stabilivolt D9 voltage stabilizing.After receiving ringing signal; The IOA1 output low level of single-chip microcomputer IC1 makes bidirectional triode thyristor Q1 conducting; The 220VAC alternating voltage is through excessive capacitor C 1, protective resistance R1, form rectifier bridge, controllable silicon Q1, stabilivolt D9 and the bigger electric current of load generating by diode D5, D6, D7 and D8, and this moment, the mu balanced circuit output power became big.After jingle bell finished, the IOA1 of single-chip microcomputer IC1 output uprised, and controllable silicon Q1 breaks off, and circuit returns low power consumpting state.
The power consumption calculation that first kind of capacity voltage dropping circuit saved is following:
During jingle bell, C1, C2 all connect, and R1=22W, C1=1 μ F, C2=0.047 μ F, C1 be much larger than C2, the total current during jingle bell
