Embodiment Construction
[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0023] Such as Figure II A radio frequency channel self-test scheme for receiving and transmitting different frequencies includes:
[0024] S101: a self-test instruction issued by the PC;
[0025] S102: The baseband module receives and executes the self-test instruction, and enters S103;
[0026] S103: The transmission module automatically configures the transmission channel and transmits electromagnetic waves of its own frequency band, and enters S104;
[0027] S104: RF switch 1 and RF switch 2 switch to the self-test circuit and enter S105;
[0028] S105: The receiving module receives the electromagnetic wave of its own frequency band sent by the sending module, and automatically matches and identifies the frequency electromagnetic wave, and e...

According to the scheme, the channel self-checking function is achieved for radio frequency receiving and transmitting schemesfor receiving and transmitting different frequencies. According to the scheme, the function completeness detection of the different frequencies receiving channel and transmitting channel can be automatically realized when the self-checking function is triggered. A traditional radio frequency communication system for receiving and transmitting different frequencies does not have a self-checking function, and if the self-checking function needs to be realized, a set of special detection system needs to be independently designed, so that the detection cost and the system complexity are improved. The scheme is mainly composed of a baseband module, a transmitting module,a receiving module, a radio frequency switch 1, a radio frequency switch 2, a transmitting filter, a receiving filter, a transmitting antenna and a receiving antenna. The functions of modulation of transmitted signals, demodulation of received signals, frequency switching, data analysis and the like can be automatically completed, and convenience is provided for product production testing, dailyfault diagnosis and daily maintenance.
Description
technical field [0001] The invention relates to a radio frequency channel self-inspection scheme for receiving and transmitting different frequencies. Background technique [0002] For traditional radio frequency communication products with different frequencies of receiving channel and transmitting channel, only special instruments such as signal source and spectrum analyzer can be used to test the function and performance during factory test and inspection. After the equipment is delivered to the customer, it is very inconvenient and difficult to use the equipment if the equipment needs to be inspected or maintained on site. In addition, the frequency, filter bandwidth and other parameters of the traditional solution are fixed at the factory, and cannot be flexibly configured or changed. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a radio frequency channel self-inspection scheme for receiving and transmi...
