Obviously, the accompanying drawings described below are some embodiments of the present disclosure. For the ordinary skill in the field, other accompanying drawings may be obtained according to these accompanying drawings without creative work.
The above purpose, technical scheme and advantages of the present disclosure will become more clearly understood from the detailed description of the technical scheme of the present disclosure provided below. Obviously, the embodiments described hereinafter are simply part embodiments of the present disclosure, but all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present disclosure without creative work are intended to be included in the scope of protection of the present disclosure.
The prior art has a problem that a communication signal cannot be transmitted on a secondary channel by simply operating a button. In order to solve the above problem, the present disclosure provides the following embodiments.
As shown in
the mainboard 1 is arranged in the shell; the radio communication module 3, the control module 2, the sound pickup module 4 and the loudspeaker module 5 are arranged on the mainboard 1; the power module is electrically connected to the radio communication module 3, the control module 2, the sound pickup module 4 and the loudspeaker module 5 respectively; the control module 2 is electrically connected to the radio communication module 3, the loudspeaker module 4 and the sound pickup module 5 respectively; the loudspeaker module 5 is electrically connected to a corresponding end of the radio communication module 3; and the sound pickup module 4 is electrically connected to a corresponding end of the radio communication module 3.
After connected to the power supply, if the radio communication module 3 does not detect any communication signal, the control module 2 controls the radio communication module 3 to monitor on the primary channel and the secondary channel alternately whether there is a valid communication signal, in the meantime the control module 2 controls the loudspeaker module 5 to keep in an off state, that is, the loudspeaker has no sound.
When the radio communication module 3 detects that there is a valid communication signal on the primary or secondary channel, the radio communication module 3 sends data to the control module 2, the control module 2 controls the loudspeaker module 5 to turn on, the loudspeaker module 5 amplifies the audio signal demodulated and output from the radio communication module 3 and pushes the loudspeaker to make a sound. In the meantime, if the radio communication module 3 detects that the signal on the current receiving channel becomes invalid, the radio communication module 3 sends data to the control module 2, the control module 2 controls the loudspeaker module 5 to stop working and controls the radio communication module 3 to continue monitoring a communication signal on the current channel within a preset time. In some optional embodiments, the radio communication module 3 continues monitoring a communication signal on the current channel within 5 seconds. If within the set time, the radio communication module 3 does not detect any valid communication signal, the control module 2 controls the radio communication module 3 to monitor a communication signal on the primary channel and the secondary channel alternately; if within the set time, the radio communication module 3 detects again a valid communication signal, the control module 2 controls the loudspeaker module 5 to turn on, that is, repeating from the start step of the receiving operation process.
Once the users press and hold down one of “PTT” and “GROUP” buttons, the sound pickup module 4 will pick up a sound and then convert it into audio signal and deliver it to the radio communication module 3, and the control module 2 controls the radio communication module 3 to transmit the communication signal to the primary channel or the secondary channel depending on which of “PPT” and “GROUP” button is pressed.
It should be noted that the computer programs involved in the present embodiment are available technology, they can be realized through a single-chip, for example, through 80051 series of single-chips. No further description is needed in the present embodiment.
The employed radio communication module in the present disclosure can receive and transmit a communication signal on the primary channel or the secondary channel, the employed control module can control the radio communication module to transmit a communication signal on the secondary channel, thereby achieving the function of simply operating a button to fire the wireless transmission on the secondary channel.
Further, the shell is provided with a PPT button which is configured to transmit a communication signal on a primary channel, and the PPT button is electrically connected to the control module 2, for easing transmitting a communication signal on the primary channel actively.
Further, the shell is provided with a GROUP button which is configured to transmit a communication signal on a secondary channel, and the GROUP button is electrically connected to the control module 2, for easing transmitting a communication signal on the secondary channel actively.
Further, the shell is provided with a channel switch button which is configured to select an available working channel number for the primary channel and the secondary channel respectively, and the channel adjustment button is electrically connected to the control module 2, for easing changing the working channel number for the two kinds of channels.
