Description
Technical field
The present invention relates to field of remote control, more particularly to a kind of remote controller for electric.
Background technology
Digiplex circuit is many in the prior art, but it is most of it is complicated, stability is poor, can not meet need
Ask, therefore the present invention relates to a kind of remote controler for this defect.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of remote controller for electric, the remote control circuitry
Simply, stability is good.
To achieve these goals, the technical solution adopted by the present invention is：A kind of remote controller for electric, including button list
Member, control chip, self-maintained circuit, the push-button unit are connected with control chip, the control chip with from exciting
Swing circuit connection；After push-button unit is pressed, the control chip defines encoded signal and defeated according to by the pin of key connection
Go out control signal to send signal through self-maintained circuit generation radiofrequency signal.
Control signal after coding is sent in self-maintained circuit after transistor amplifier.
The self-maintained circuit is LC self-maintained circuits, and each circuit part of the remote controler is welded on
On pcb board, the inductance in LC self-maintained circuits passes through snakelike trace inductance.
Power supply BT1 is connected through resistance R1 with the base stage of triode Q1, and the emitter of triode Q1 is connected with power supply, collector
It is grounded by capacitance C2 and is connected at the same time by resistance R2 with No. 2 pins of control chip U1；The base stage of triode Q1 is through resistance R3
Afterwards the 8 of control chip U1,7,6, No. 5 pins are connected respectively by four buttons S1, S2, S3, S4 respectively, the 3 of control chip U1
Number pin is grounding pin, and No. 4 pins are output pin, and base stage of No. 4 pins with triode Q2 after resistance R5 is connected.No. 4
Pin after resistance R6, light emitting diode D1 by being grounded.The base stage of triode Q2 is connected emitter by capacitance C6 with emitter
It is grounded by resistance R7, resistance R7 shunt capacitance C7, emitter is connected by capacitance C5 with collector, the collector of triode Q2
It is connected by inductance L1 with the collector of triode Q1, the collector of triode Q1 is grounded through C2；In inductance L1 and triode Q2
Collector between, respectively pass through capacitance C3 ground connection, capacitance C1 ground connection.
Control chip U1 is the coding chip of model EV1528.
The advantage of the invention is that：Controller circuit structure is simple, the signal stabilization sent, and on PCB is welded on
When self-maintained circuit in inductance use snakelike trace inductance instead, it is possible to reduce buy the cost of inductance, improve production efficiency；Base
Control signal is produced after amplified signal again by LC self-maintained circuits transmitting radiofrequency signal in coding chip, can be accurate
Corresponding control signal is sent, and EV1528 coding chip energy consumptions are small；And only after pushing button, triode Q1 is just led
Logical, coding chip ability powered operation, reduces energy consumption.
Brief description of the drawings
Mark in the content and figure expressed below each width attached drawing of description of the invention is briefly described：
Fig. 1 is remote controller for electric schematic diagram of the present invention.
Embodiment
It is further detailed to the embodiment work of the present invention by the description to optimum embodiment below against attached drawing
Thin explanation.
As shown in Figure 1, the controller circuitry of electric car is welded and is arranged on pcb board, circuit diagram includes control chip U1,
The model EV1528 of U1.Power supply BT1 is connected through resistance R1 with the base stage of triode Q1, and emitter and the power supply of triode Q1 connect
Connect, collector is grounded by capacitance C2 and is connected at the same time by resistance R2 with No. 2 pins of control chip U1；The base stage of triode Q1
The 8 of control chip U1,7,6, No. 5 pins are connected respectively by four buttons S1, S2, S3, S4 respectively after resistance R3, control core
No. 3 pins of piece U1 are grounding pin, and No. 4 pins are output pin, and No. 4 pins connect after resistance R5 with the base stage of triode Q2
Connect.No. 4 pins after resistance R6, light emitting diode D1 by being grounded.The base stage of triode Q2 is connected by capacitance C6 with emitter
Emitter is grounded by resistance R7, and resistance R7 shunt capacitance C7, emitter is connected by capacitance C5 with collector, triode Q2's
Collector is connected by inductance L1 with the collector of triode Q1, and the collector of triode Q1 is grounded through C2；In inductance L1 and three
Between the collector of pole pipe Q2, it is grounded respectively by capacitance C3 ground connection, capacitance C1.
The operation principle of circuit be by pressing a button in S1, S2, S3, S4 after, chip U1 according to it is default should
The corresponding control encoded signal of button, as S1 for locking, then after S1 is pressed, U1 coding locking control signal, and pass through No. 4 pins
Output control signal, at this time diode D1 shine, provide the display that control signal is sent；Control signal is through triode Q2 to signal
Amplification, then launches the radiofrequency signal after encoding to control electric car by L1, C3, C5, C7 self-maintained circuit formed.
In production, on circuit boards, the inductance L1 in self-maintained circuit replaces purchase using snakelike trace inductance for whole circuit welding
The inductance element or chip inductor bought, so as to reduce SMT machines attachment welding required when cost and welding, reduce into
