Technical field
The utility model relates to a kind of wireless frequency modulation receiver, is specifically related to the open-air wireless frequency modulation receiver of a kind of infrared remote control.
Background technology
At present, open-air FM receiver is the capital equipment that FM broadcasting receives, and accomplishes the functions such as receiving demodulation, switching on and shutting down control and audio power amplification of FM broadcasting.Wherein, audio drive circuitry directly is connected with the loudspeaker of uphanging, to realize " point is logical " or " the village village is logical " broadcasting.This equipment generally depends on the power taking on the spot of electric power bar line, nonlocal aerial suspension out of office, and nobody holds and keeps.
As shown in Figure 1, existing open-air wireless frequency modulation receiver adopts microprocessor control FM reception head, and receive frequency is variable, can receive the f-m broadcast station of the arbitrary frequency of 88 ~ 108MHz.The receiver panel adopts 4 figure place sign indicating numbers to show, 4 are touched button and are defined as menu, left and right, OK respectively, accomplish the inquiry and the setting of various parameters.This equipment also has the addressing encoding function, can realize functions such as shutdown automatically, manual volume control according to carrier wave.
Existing wireless open-air FM reception equipment is uphang on electric pole; Overhead highly generally at 5 ~ 8 meters, cover for guaranteeing wider broadcasting, the position of loudspeaker can select peak to install; Generally can cross the top that the electric power netting twine is installed in the electric power bar, farther to guarantee that sound transmission gets; First installation of this equipment and later maintenance difficulty are very big; If need the change receive frequency, regulate volume or suspected fault occurs; The work high above the ground personnel must rely on movable aerial ladder to climb up, operation inspection on the panel of equipment, and to watch out for Danger Electric shock risk constantly; After equipment shuts down inefficacy automatically, also must climb up power supply is broken.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: be directed to the deficiency of prior art, provide a kind of infrared remote control that utilizes to be controlled at the open-air wireless frequency modulation receiver of infrared remote control that functions such as frequency change, volume adjustment, automatic switching control can be realized in ground.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: provide a kind of infrared remote control open-air wireless frequency modulation receiver; Comprise microprocessor, FM reception module, volume control module, power amplifier module, microprocessor is connected with power amplifier module with the FM reception module respectively, it is characterized in that: also comprise infrared receiving module; Infrared receiving module one end is connected with microprocessor, and the other end is used to receive the infrared signal of IR remote controller emission; Said volume control module is the electronic sound volume control module, and the electronic sound volume control module is connected with microprocessor.
Said IR remote controller is omnipotent TV remote controller.
Said infrared receiving module is an infrared receiving terminal.
Said FM reception module is the FM reception head.
In sum; The open-air wireless frequency modulation receiver of the infrared remote control that the utility model provides is through setting up infrared receiving terminal; And change manual volume control module is the electronic sound volume control module; Make the utility model equipment can accomplish functions such as frequency change, volume adjustment, signal strength signal intensity inquiry, addressing encoding setting, automatic switching control, local forced shutdown on ground; The dangerous hidden danger of no work high above the ground, and alleviated equipment just installation and later maintenance difficulty greatly, improved equipment control efficient.
Description of drawings
Fig. 1 is the structured flowchart of former open-air wireless frequency modulation receiver.
The structured flowchart of the open-air wireless frequency modulation receiver of the infrared remote control that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to be described in detail:
As shown in Figure 2; The open-air wireless frequency modulation receiver of the infrared remote control that the utility model provides comprises microprocessor, FM reception head, electronic sound volume control module, power amplifier module and infrared receiving terminal, also outer telescopic antenna and the loudspeaker of being provided with of this wireless frequency modulation receiver; Wherein, microprocessor is connected with power amplifier module with FM reception head, electronic sound volume control module respectively; Infrared receiving terminal one end is connected with microprocessor, and the other end is used to receive the infrared signal of IR remote controller emission, and IR remote controller is the omnipotent TV remote controller that standard is sold on the market.
The first end of FM reception is connected with telescopic antenna; Its frequency output terminal is connected with the electronic sound volume control module; The audio signal output end of electronic sound volume control module is connected with power amplifier module, and power amplifier module is connected with at least one loudspeaker through the lead-out terminal on the power amplifier module; Microprocessor is connected with infrared receiving terminal with FM reception head, electronic sound volume control module, power amplifier module respectively, is used for processes such as control frequency change, volume control and infrared remote control.
Said electronic sound volume control module is for adopting the electronic sound volume controller of PT2257 chip.
Said IR remote controller is omnipotent TV remote controller, and the button of this remote controller is a lot, comprises numerical key, directionkeys and function key, defines its function of use arbitrarily according to program; And the microprocessor of existing open-air FM receiver is upgraded to the more chip of large program memory capacity, and coding is accomplished all functions that infrared remote control can be accomplished again.
Through IR remote controller is that the may command height is at 10 meters open-air wireless frequency modulation receivers with interior the utility model on ground; Can change receive frequency, receiving wave range, control coding, volume etc., check signal strength signal intensity, dispatch from the factory the string number ...
