Abstract
The utility model provides a remote controller for orientation of TV antennae, which is composed of an ultrasonic transmitter, an ultrasonic receiver, a motor, and an antenna amplifier. The rotation of an antenna can be remotely controlled when hands control the switch of the ultrasonic transmitter, the rotation of the antenna can also be manually controlled on the ultrasonic receiver when necessary, and the gain of the antenna amplifier can also be controlled on the ultrasonic receiver. The ultrasonic transmitter and the ultrasonic receiver are both arranged in two small plastic box-shaped housing, and the motor is arranged on the upper side of an antenna mounting. The utility model has the advantages of simple structure, and low cost; particularly, the utility model is suitable for TV wires which are installed on the balconies of resident families.
Description
The remote controller that a kind of remote control TV receiver sky turns to belongs to technical field of radio.
The antenna of domestic television set is difficult to make a plurality of channel programs can both obtain satisfied view reception effect, generally all will be according to different television channels, make reception antenna be in different directions, just can obtain best view reception effect, existing control antenna transfer, all very complicated, and cost an arm and a leg.
The purpose of this utility model provides a kind of according to different television channels, and both remote-controlled television antenna turns to, and the television antenna of may command antenna gain turns to remote controller again.
Scheme of the present utility model is ultrasonic transmitter of design and ultrasonic receiver, the electronic circuit part of its supersonic generator, be installed in respectively in the small-sized box-like housing that two plastic materials make, a DC motor is installed on the antenna pedestal and with antenna support column gear and is connected, ultrasonic transmitter emission 40KC ultrasonic signal is received the back by ultrasonic receiver and amplifies, be transformed to the direct voltage drive motor, the motor drives antenna rotates, the direct-current working volts of antenna amplifier antennafire are provided by ultrasonic receiver, and the high-frequency signal after with same high frequency cable antenna amplifier antennafire being amplified is connected with ultrasonic receiver with direct voltage, adjust this direct voltage, just the radio television signal after adjustable antenna Amplifier Gain, ultrasonic receiver are amplified antenna amplifier antennafire with another root high frequency cable is given television receiver.
The circuit and the structure that the utility model has the advantages that ultrasonic receiver and ultrasonic transmitter are all very simple, and performance is latent fixed reliable, and cost is low, and is easy to use, are particularly suitable for the come on TV use of antenna of resident's balcony.
