The operating system of the terminal may include, but is not limited to, for example, the FLYme operating system, the Android operating system, the IOS operating system Symbian operating system, the Black Berry operating system, the Windows Phone operating system, and so on.
It should be understood that the current transmitted by the low voltage transmission circuit 101 is a micro current, which does not cause interference to the antenna 102 for receiving and transmitting rf signals or causes minimal interference to the receiving and transmitting rf signals. The second end a of the radio frequency circuit 103 is configured to receive a current transmitted by the low voltage transmission circuit 101 and a radio frequency signal transmitted by the radio frequency transceiving system, and when the second end a of the radio frequency circuit 103 receives the radio frequency signal, the radio frequency signal is transmitted to the antenna 102, the radio frequency signal is transmitted through the antenna 102, and when the second end a of the radio frequency circuit 103 receives the current transmitted by the low voltage transmission circuit 101, the light emitting diode LED connected to the first end B of the radio frequency circuit 103 is driven to emit light, so that multiplexing of the radio frequency circuit 103 is implemented, a separate driving circuit for the light emitting diode LED is avoided, circuits in the radio frequency transceiving module are reduced, the structure of the radio frequency transceiving module is further reduced, and the assembly difficulty is reduced; meanwhile, the Light Emitting Diode (LED) is driven by multiplexing the radio frequency circuit 103, when the radio frequency circuit 103 or the antenna 102 breaks down to cause the circuit to be blocked, the LED can not drive the light to emit, and then whether the radio frequency circuit 103 and/or the antenna 102 breaks down or not can be quickly determined through the LED, so that the effect of visually maintaining the radio frequency transceiving component is achieved, the problem troubleshooting time is shortened, and the fault maintenance efficiency is improved.
In some examples of this embodiment, the radio frequency transceiver component further comprises: a processor U1, a general purpose output interface (GPIO) of the processor U1 is connected with the input terminal of the low voltage transmission circuit 101, and the processor U1 is used for outputting low voltage to the low voltage transmission circuit 101. As shown in fig. 2, the input end of the low voltage transmission circuit 101 is directly connected to the general output interface of the processor U1, the processor U1 directly outputs current, and the current passes through the low voltage transmission circuit 101 to drive the light emitting diode LED through the radio frequency circuit 103, wherein the output interface of the processor U1 has the characteristic of low voltage micro current, so that the output micro current does not cause interference in receiving and transmitting radio frequency signals by the antenna 102, or cause minimal interference in receiving and transmitting radio frequency signals;
bearing the above example, in this example, the processor U1 in the multiplexing radio frequency transceiver module is used to supply power to the light emitting diode LED, and when there is a need to make the light emitting diode LED normally on or normally off, the instructions of 0 and 1 may be set by software to directly control the processor U1 to output or stop outputting current; meanwhile, the software can also set that when the antenna 102 is detected to transmit and receive radio frequency signals, the control processor U1 outputs or stops outputting current so as to light or close the light emitting diode LED, and further play a role in reminding the current working state of the antenna 102; for example, in the software, setting 0 as normally closed and 1 as normally on, when the light emitting diode LED needs to be normally closed, outputting 0 to the processor U1 to make the processor U1 stop outputting current to the low voltage transmission circuit 101, and when the light emitting diode LED needs to be normally on, outputting 1 to the processor U1 to make the processor U1 continuously output current to the low voltage transmission circuit 101; for another example, it is configured that when it is detected that the antenna 102 is currently transmitting and receiving the radio frequency signal, the processor U1 outputs a current to the low voltage transmission circuit 101 to drive the light emitting diode LED to emit light, and when it is detected that the antenna 102 is not currently transmitting and receiving the radio frequency signal, the processor U1 stops outputting the current to the low voltage transmission circuit 101 to stop driving the light emitting diode LED to emit light.
In some examples of this embodiment, the processor U1 in the multiplexing radio frequency transceiver module provides a driving current for the light emitting diode LED, so that an independent power supply is not provided for the light emitting diode LED, circuits in the radio frequency transceiver module are further reduced, the structure of the radio frequency transceiver module is reduced, and the effect of reducing the assembly difficulty is achieved.
In some examples of the present application, as shown in fig. 3, the radio frequency transceiver component further comprises: a low voltage power source 104, wherein the low voltage power source 104 is connected to an input terminal of the low voltage transmission circuit 101, and the low voltage power source 104 is configured to output a current to the low voltage transmission circuit 101. It should be understood that the input terminal of the low voltage transmission circuit 101 is directly connected to the output interface of the low voltage power source 104, and the current output by the low voltage power source 104 passes through the low voltage transmission circuit 101 and drives the light emitting diode LED through the radio frequency circuit 103, wherein the output of the low voltage power source 104 has the characteristic of low voltage micro-current, so that the micro-current output by the low voltage power source does not cause interference with the transmission and reception of the radio frequency signals by the antenna 102, or causes minimal interference with the transmission and reception of the radio frequency signals. In some examples, the low voltage power source 104 is a constant current source, and outputs a constant low current, which does not interfere with the transmission and reception of the rf signals by the antenna 102 or causes little interference with the transmission and reception of the rf signals.
As for the above example, when there is a need to make the light emitting diode LED normally on or normally off, the low voltage power supply 104 may be controlled to output or stop outputting current by setting the instructions of 0 and 1 through software; meanwhile, the software can also be set to control the low-voltage power supply 104 to output or stop outputting current when the antenna 102 is detected to transmit and receive radio-frequency signals, so as to light or close the light-emitting diode (LED), and further play a role in reminding the current working state of the antenna 102; for example, in the software, setting 0 as normally closed and 1 as normally on, when the light emitting diode LED needs to be normally closed, outputting 0 to the low voltage power supply 104 to stop outputting current to the low voltage transmission circuit 101 by the low voltage power supply 104, and when the light emitting diode LED needs to be normally on, outputting 1 to the low voltage power supply 104 to keep outputting current to the low voltage transmission circuit 101 by the low voltage power supply 104; for another example, it is configured that when it is detected that the antenna 102 is currently transmitting and receiving the radio frequency signal, the low voltage power supply 104 outputs a current to the low voltage transmission circuit 101 to drive the light emitting diode LED to emit light, and when it is detected that the antenna 102 is not currently transmitting and receiving the radio frequency signal, the low voltage power supply 104 stops outputting the current to the low voltage transmission circuit 101 to stop driving the light emitting diode LED to emit light.
In the present example, a low voltage power supply 104 is provided to supply a micro current to multiplex the radio frequency circuit 103 through the low voltage transmission circuit 101, and the light emitting diode LED connected to the first end B of the radio frequency circuit 103 is driven, so that multiplexing of the radio frequency circuit 103 is realized, a driving circuit is not separately provided for the light emitting diode LED, circuits in the radio frequency transceiving module are reduced, the structure of the radio frequency transceiving module is reduced, and the assembly difficulty is reduced; meanwhile, the Light Emitting Diode (LED) is driven by multiplexing the radio frequency circuit 103, when the radio frequency circuit 103 or the antenna 102 fails to work and the circuit is blocked, the LED can not be driven to emit light, so that whether the radio frequency circuit 103 and/or the antenna 102 fails or not can be quickly determined through the LED, the effect of visually maintaining the radio frequency circuit 103 and the antenna 102 is achieved, the problem troubleshooting time is shortened, and the failure maintenance efficiency is improved.
