In the present embodiment, the short-circuit protection circuit 46, the second isolation circuit 42, the led driving circuit 43, and the rf circuit 44 are all disposed on the tuner.
For direct current signals, the antenna has two structures of short circuit and open circuit. When the tuner is externally connected with the antenna with the short-circuit structure, the direct current signal output by the light emitting diode driving circuit 43 is short-circuited, and even burns out the tuner. The present embodiment can prevent such a situation from occurring. Through the short-circuit protection circuit 46, once the external antenna is short-circuited, overcurrent protection is realized through the PW2601 chip, and the output maximum current is limited.
A remote controller comprises the tuner. The remote controller can send the remote control information to the tuner, and can also read the remote sensing information returned by the tuner.
In a communication system, an antenna is a radio frequency device that transmits and receives electromagnetic waves, driven by radio frequency signals; and the led 30 is driven by a dc signal. The radio frequency signal and the direct current signal are far apart in frequency spectrum, so that the antenna and the light emitting diode 30 can be shared on the same coaxial feeder 50 through the first isolation circuit 41 and the second isolation circuit 42 without interfering with each other. That is, electromagnetic wave signals transmitted and received by the antenna are transmitted through the coaxial feeder 50, and control signals of the light emitting diode 30 are also transmitted through the coaxial feeder 50, and technically, radio frequency signals and direct current signals are multiplexed with the same coaxial feeder 50.
As shown in fig. 13, the trend for the radio frequency signal is as follows: the radio frequency signal outputted from the tuner main control circuit 45 is outputted to the first vibrator 21 and the second vibrator 22 via the radio frequency circuit 44, the second isolation circuit 42, the coaxial connector 60 and the coaxial feeder 50 in order, and radiated.
As shown in fig. 12, the trend for the dc signal is as follows: the direct current signal outputted from the tuner main control circuit 45 is outputted to the light emitting diode 30 through the light emitting diode driving circuit 43, the short circuit protection circuit 46, the second isolation circuit 42, the coaxial connector 60, the coaxial feeder 50, the first vibrator 21, and the first isolation circuit 41 in this order.
Since the light emitting diode 30 is driven by a direct current signal, it is possible to judge whether the connection of the antenna to the tuner is good by checking the brightness or flickering of the light emitting diode 30, thereby avoiding the damage of the tuner caused by long-time use of the damaged antenna or the coaxial connector 60.
If the brightness or flicker of the LED 30 is normal, the connection between the antenna and the tuner is good;
if the brightness of the light emitting diode 30 is darkened or blinked abnormally, which means that the connection of the antenna to the tuner is not good, it is necessary to further detect whether the coaxial connector 60 or the coaxial feed line 50 is damaged.
The utility model is mainly characterized in that the LED is integrated on the antenna through the cooperation of the first isolation circuit and the LED, so that the antenna has a status indication function;
secondly, through the matching of the light emitting diode driving circuit, the first isolation circuit and the second isolation circuit, the radio frequency signal and the direct current signal multiplex the same coaxial feeder, so that the functions of originally sending and receiving electromagnetic waves on the antenna are not affected by the direct current signal, and meanwhile, the light emitting diode on the antenna can be driven, the two are not interfered with each other, and the synchronous operation can be realized;
moreover, by the short-circuit protection circuit, the burning of the tuner caused by the wrong connection of the antenna can be avoided, the reliability and the safety of the tuner are improved, and the service life of the tuner is prolonged;
and judging whether the antenna is well connected or not by observing the brightness or flickering condition of the light emitting diode, so that the damage of the tuner caused by long-time use of the damaged antenna or coaxial connector is avoided, and the service life of the tuner is prolonged.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the technical scope of the present utility model, so that any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
