Fig. 1 is a block diagram of a remote signal transmission device according to an embodiment of the present invention.
Referring to fig. 1, the remote signal transmission apparatus for data interaction between an audio device 100 and an analysis device 200 includes a controller 10, a clock shaping circuit 20, and a data shaping circuit 30;
a first output of the controller 10 is connected to a controlled terminal of the clock shaping circuit 20, an input of the clock shaping circuit 20 is connected to a clock signal output terminal of the analysis device 200 to receive the clock signal output by the analysis device 200, and an output of the clock shaping circuit 20 is connected to a clock signal input terminal of the audio device 100 to deliver the shaped clock signal to the audio device 100.
A second output of the controller 10 is connected to a controlled terminal of the data shaping circuit 30, an input of the data shaping circuit 30 is connected to a data output of the audio device 100, and an output of the data shaping circuit 30 is connected to a data input of the analysis device 200.
The clock shaping circuit 20 is configured to recover the waveform of the clock signal output by the analysis device 200 and adjust the amplitude of the clock signal output by the analysis device 200 to adapt to the audio device 100. The clock signal shaping circuit 20 may adjust the amplitude of the clock signal output by the analysis device 200 up and down, and the amplitude of the adjusted clock signal is between 0.6V and 5V, so that the clock signal generated by the analysis device 200 can be used to trigger most of the audio devices 200 to generate the data signal by adjusting the amplitude of the clock signal.
The data shaping circuit 30 is used for restoring the waveform of the data signal output by the audio device 100 and adjusting the amplitude of the data signal output by the audio device 100, so that the analysis device 200 can completely capture the data signal output by the audio device 100. The data shaping circuit 30 may adjust the amplitude of the data signal output by the audio device 100 up and down, and the amplitude of the adjusted data signal is between 0.6V and 5V, so that the analysis device 200 may be ensured to completely capture the data signal output by the audio device 100 by adjusting the amplitude of the data signal, so as to smoothly analyze the performance of the audio device 100.
In practical applications, when the analysis device 200 is used to analyze the data signal of the audio device 100, a corresponding clock signal needs to be provided for the audio device 100 to trigger the audio device 100 to generate the data signal, where the data signal includes the acoustic information parameters of the audio device 100. In the embodiment, the audio device 100 is provided with a clock signal through the analysis device 200 to trigger the audio device 100 to generate a data signal, wherein the frequency of the clock signal generated by the analysis device 200 is variable, the frequency range of the generated clock signal is 768KHZ to 3.072MHZ, and a user can control the frequency of the clock signal generated by the analysis device 200 according to actual needs. It will be appreciated that in other embodiments, the clock signal may be provided to the audio device 100 by other external devices as well. During the transmission of the clock signal generated by the analysis apparatus 200 to the audio apparatus 100, the clock signal is prone to waveform distortion due to the distance between the analysis apparatus 200 and the audio apparatus 100, and the signal amplitude of the clock signal generated by the analysis apparatus 200 may not be adapted to the amplitude of the clock signal required by the audio apparatus 100.
Therefore, the present embodiment performs shaping processing on the clock signal generated by the analysis device 200 by setting the clock shaping circuit 20 to restore the waveform of the clock signal, and at the same time, adjusts the amplitude of the clock signal to adapt the amplitude of the shaped clock signal to the amplitude of the clock signal actually required by the audio device 100; for example, the amplitude of the clock signal required for the audio apparatus 100 is set to 3V and the duty ratio is set to 50%. Wherein the amplitude of the clock signal generated by the analysis apparatus 200 is 2V and the duty ratio is 50%. However, the clock signal generated by the analysis device 200 is transformed into a sine wave during transmission, and then, after entering the clock shaping circuit 20, the clock signal is restored to a clock signal with a duty ratio equal to 50% by the clock shaping circuit 20, and the clock shaping circuit 20 adjusts the amplitude of the clock signal from 2V to 3V according to the first control signal of the controller 10, so that the clock signal transmitted to the audio device 100 can smoothly trigger the audio device 100 to generate the data signal.
In order to avoid that the data signal generated by the audio device 100 cannot be correctly analyzed by the analysis device 200 due to serious distortion, the data shaping circuit 30 of the embodiment further shapes the data signal generated by the audio device 100 to restore the waveform of the data signal, and at the same time, the amplitude of the data signal generated by the audio device 100 is increased to facilitate the analysis device 200 to completely capture the data signal; for example, the data signal generated by the audio device 100 is a square wave with an amplitude of 0.5V, and the data signal is transformed into a sine wave during transmission, then the data signal is restored to the square wave by the data shaping circuit 30 after entering the data shaping circuit 30, and the data shaping circuit 20 increases the amplitude of the data signal according to the second control signal of the controller 10, for example, from 0.5V to 2V, so that the analysis device 200 successfully captures the data signal and performs performance analysis on the audio device 100 according to the captured data signal.
That is to say, according to the technical solution of the present invention, the clock shaping circuit 20 is configured to restore the waveform of the clock signal generated by the analysis device 200, and adjust the amplitude of the clock signal generated by the analysis device 20 to be suitable for the audio device 100, so as to trigger the audio device 100 to generate the data signal; meanwhile, the waveform of the data signal generated by the audio device 100 is restored by the data shaping circuit 30, and the amplitude of the data signal generated by the audio device 100 is increased, so that the analysis device 200 can smoothly capture the complete data signal for audio analysis.
Optionally, referring to fig. 2, in an embodiment, the clock shaping circuit 20 includes a clock signal reference circuit 201 and a clock signal shaping circuit 202;
the input of the clock signal reference circuit 201 is connected to a first output of the controller 10, and the output of the clock signal reference circuit 201 is connected to the reference signal input of the clock signal shaping circuit 202; an input of the clock signal shaping circuit 202 is connected to a clock signal output of the analysis device 200 for receiving the clock signal output by the analysis device 200, and an output of the clock signal shaping circuit 202 is connected to a clock signal input of the audio device 100 for delivering the shaped clock signal to the audio device 100.
In this embodiment, the clock signal reference circuit 201 may be an LDO (low dropout regulator), or may be implemented by a circuit including components such as a zener diode or a voltage regulator. The clock signal reference circuit 201 is configured to generate a reference voltage to the clock signal shaping circuit 202 according to a first control signal of the controller 10, and provide the reference voltage for the clock signal shaping circuit 202; the reference voltage generated by the clock signal reference circuit 201 ranges from 0.6V to 5V.
The clock signal shaping circuit 202 may be a schmitt trigger circuit, or may be implemented by a circuit including a comparator or a diode. The clock signal shaping circuit 202 is used to recover the waveform of the clock signal generated by the analysis device 200 and to adjust the amplitude of the clock signal in accordance with the received reference voltage to adapt the audio device 100. For example, the amplitude of the clock signal required by the audio device 100 is set to be 3V, the duty ratio is set to be 50%, the rising edge is 10ns, and the falling edge is 10 ns; wherein, the amplitude of the clock signal generated by the analysis device 200 is 2V, the duty ratio is 50%, the rising edge is 10ns, and the falling edge is 10 ns; however, the clock signal generated by the analysis device 200 is distorted into a sine wave during transmission. In this case, the clock signal reference circuit 201 may be controlled to generate a reference voltage of 3V to the clock signal shaping circuit 202, and then, after the clock signal generated by the analysis device 200 enters the clock signal shaping circuit 202, the clock signal is restored to the clock signal with a duty ratio equal to 50%, a rising edge of 10ns, and a falling edge of 10ns by the clock signal shaping circuit 202, and the clock signal shaping circuit 202 adjusts the amplitude of the clock signal from 2V to 3V, that is, the amplitude of the clock signal generated by the analysis device 200 is adjusted to be consistent with the amplitude of the reference voltage generated by the clock signal reference circuit 201, so that the clock signal transmitted to the audio device 100 can smoothly trigger the audio device 100 to generate the data signal.
Optionally, referring to fig. 3, in an embodiment, the clock signal reference circuit 201 includes a first electronic switch 2011, a first feedback circuit 2012 and a first operational amplifier 2013;

A first output terminal of the controller 10 is a D/a pin of the controller 10, an analog voltage output by the D/a pin of the controller 10 is applied to an inverting input terminal of the first operational amplifier 2013, and compared with a sampling voltage applied to a non-inverting input terminal of the first operational amplifier 2013 by the first feedback circuit 2012, a difference between the analog voltage and the sampling voltage is amplified by the first operational amplifier 2013, and then a voltage drop of the first electronic switch 2011 is controlled, so that a reference voltage is stably output.

The data signal shaping circuit 302 is used to recover the waveform of the data signal generated by the audio device 100 and adjust the amplitude of the data signal according to the received reference voltage, so that the analysis device 200 can completely capture the data signal. For example, the data signal generated by the audio device 100 is set to be a square wave with an amplitude of 0.5V; however, the data signal generated by the audio device 100 is distorted into a sine wave during transmission, and the amplitude of the data signal generated by the audio device 100 is too small to be captured completely by the analysis device 200. In this case, the data signal reference circuit 301 may be controlled to generate a reference voltage of 2V to the data signal shaping circuit 302, and then, after the data signal generated by the audio device 100 enters the data signal shaping circuit 302, the data signal is restored to a square wave by the data signal shaping circuit 302, and the data signal shaping circuit 302 adjusts the amplitude of the data signal from 0.5V to 2V, that is, the amplitude of the data signal generated by the audio device 100 is adjusted to be consistent with the amplitude of the reference voltage generated by the data signal reference circuit 301, so that the analysis device 200 can smoothly capture the data signal to perform performance analysis on the audio device 100, and it is avoided that the analysis device cannot completely capture the data signal due to the too small amplitude of the data signal generated by the audio device 100.
