The invention discloses a transmitting and detecting method of a transmitting and receiving assembly. An FPGA logic control circuit and a detection control terminal are additionally arranged in a radio frequency circuit; a detection control terminal is used for sending a detection control signal which is used for controlling the access of a radio frequency channel and an antenna and controlling the access of the radio frequency channel and a DAC chip and a power supply to the radio frequency channel and an FPGA logic control circuit, so that the FPGA logic control circuit carries out emissiondetection judgment on the returned detection mark signal when the radio frequency signal of the radio frequency channel is output. On the basis of a radio frequency channel, a DAC module used for detection control equipment and radio frequency emission and an FPGA logic control circuit used for detection result judgment and output are arranged. The technical problem that in the prior art, the judgment precision of successful transmission of signals on a receiving and transmitting assembly is not high is solved.
Description
technical field [0001] The invention relates to the field of communication, in particular to a transmission detection method of a transceiver component. Background technique [0002] When the transceiver component is performing normal transmission operations, it needs to know whether the signal is actually transmitted. The detection (amplitude demodulation) is the inverse process of the amplitude modulation. Through the detection operation, it is possible to know whether the signal is transmitted through the antenna. [0003] At present, the circuits that realize the detection are all analog circuits, and the detection circuit is mainly composed of three parts, namely: a high-frequency modulated signal source, a nonlinear device, and an RC low-pass filter. The output of this kind of detector will depend on the amplitude of the signal (there is no definite threshold), and when the transceiver component transmits normally, the amplitude of the wave position signal is also unce...
