Description
Technical field
Circuitry field is the utility model is related to, more particularly to a kind of orderly peak clipping signal of distributing air-conditioning receives dress
Put.
Background technology
Modern air conditioning is already into essential daily necessities in for people's lives, but air-conditioning was remotely controlled in use instantly
Jitter is received in journey, or receives signal by mistake, so as to cause air-conditioning to malfunction, user's use is seriously affected, increases at the same time
Add the expense that air-conditioning uses.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of orderly peak clipping signal receiving device of distributing air-conditioning
Technical problem, to achieve the above object the utility model use following technical scheme：
A kind of orderly peak clipping signal receiving device of distributing air-conditioning, signal receiving device built-in signal receiving circuit, circuit
The 1 port ground connection of chips D1,6 ports of chip D1 connect -5V voltages through inductance L1, and inductance L1 is grounded through capacitance C4, while core
6 ports of piece D1 are grounded through capacitance C6, and 12 ports of chip D1 connect+15V power supplys, while 12 ports of chip D1 are respectively through capacitance
C1 and capacitance C2 ground connection, 10 ports of chip D1 are grounded through radio frequency (RF) coaxial connector SMA, and 9 ports of chip D1 connect through inductance L2+
5V power supplys, inductance L2 are grounded through capacitance C3, while 9 ports of chip D1 are grounded through capacitance C7, the port ground connection of chip D1.
On the basis of above-mentioned technical proposal, the chip D1 uses GD4251Y-4 type PIN photodiodes.
GD4251Y-4 types PIN photodiode in the signal receiving circuit of the utility model design has high bandwidth, spirit
The characteristics of high and low power consumption of sensitivity, high-responsivity, so as to improve integrated circuit operation stability, sensitivity, also reduce circuit operation
Power consumption, it is cost-effective.
Brief description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
A kind of orderly peak clipping signal receiving device of distributing air-conditioning, signal receiving device built-in signal receiving circuit, circuit
The 1 port ground connection of chips D1,6 ports of chip D1 connect -5V voltages through inductance L1, and inductance L1 is grounded through capacitance C4, while core
6 ports of piece D1 are grounded through capacitance C6, and 12 ports of chip D1 connect+15V power supplys, while 12 ports of chip D1 are respectively through capacitance
C1 and capacitance C2 ground connection, 10 ports of chip D1 are grounded through radio frequency (RF) coaxial connector SMA, and 9 ports of chip D1 connect through inductance L2+
5V power supplys, inductance L2 are grounded through capacitance C3, while 9 ports of chip D1 are grounded through capacitance C7, the port ground connection of chip D1.
The chip D1 uses GD4251Y-4 type PIN photodiodes.
When the signal of the utility model design receives circuit operation, large capacity tantalum capacitance filters out low-frequency noise, small capacitances and
Magnetic bead forms L-type filter circuit, filters out high-frequency noise, and the DC channel of a localization is provided for device, lowers printed circuit
In rush of current peak value, reduce ripple on power supply and ground level, noise and " burr ".Shielding processing refers to that suppressing electromagnetism does
Disturb propagation in space.With reference to the size requirement of optical receiving system, while to reduce external electromagnetic interference, circuit board shape
Circle is designed as, and optical receiving system external firmware is combined closely, the one side of plank outwardly only arranges plug-in unit, and whole
Copper is applied in face, forms the component such as good shielded layer, capacitance, magnetic bead and is all placed in the inside, does not receive external disturbance substantially, from
Influence of the body radiation interference to circuit substantially reduces.With reference to the requirement of optical receiving system size and consideration easy for installation, screen is chosen
The preferable SMA plug-in units transmission signal of covering property.Except necessary signal lead and power supply cabling on circuit board, should spread as far as possible
Ground, reduces grounding wire impedance with larger ground level.Full page wiring uses straight line and camber line, reduces signal radiation.Circuit by
Add optical filter before optical system, filter out spuious optical noise.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from the principle of the utility model with spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
