Problems solved by technology

As far as the existing production technology is concerned, when the power-on inspection of the system is performed, the working method of the airborne finished product can only be simulated by means of short circuit, such as frequency data bus, audio analog information and radio frequency analog information, etc. The operation method is complicated and It takes a long time, and it may cause burnout of the parts on the machine due to incorrect short-circuit operation, which poses a great safety hazard

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] A method for testing the transmitting function of ultra-short-wave radio stations, such as figure 1 shown, including:

[0013] The external power supply connects the 28V DC power supply to the UHF radio connector 1 through the power distribution unit 5;

[0014] The audio signal transmission unit 4 sends the analog voice signal from the audio signal generator to the signal processing unit 3 after filtering and amplifying;

[0015] The 429 data transmission and control / display unit 2 generates the working frequency information and compares the ultrashort wave radio working frequency information of the ultrashort wave radio connector 1, the ultrashort wave radio connector 1 is selected and the 429 data transmission and control / display unit 2 generates the working frequency The operating frequency of the consistent ultrashort wave station is sent to the...

Abstract

The invention belongs to the field of avionics, and proposes a method for testing a transmission function of an ultrashort radio station. The method comprises the steps that an audio signal transmission unit (4) enables an analog voice signal from an audio signal generator to be filtered and amplified and then transmitted to a signal processing unit (3); a 429 data transmission and control / display unit (2) generates working frequency information, and the working frequency information is compared with the working frequency information of the ultrashort radio station of an ultrashort radio station connector (1); the ultrashort radio station connector (1) selects working frequency of the ultrashort radio station, wherein the working frequency is consistent with the working frequency generated by the 429 data transmission and control / display unit (2), and the working frequency is transmitted to the signal processing unit (3); the signal processing unit (3) modulates the selected working frequency of the ultrashort radio station through employing the analog voice signal, and forming a carrier radio frequency signal with audio information; and the signal processing unit (3) enables the carrier radio frequency signal with audio information to be transmitted to a comprehensive tester for interpretation through a coaxial load.

Description

technical field [0001] The invention belongs to the field of avionics and relates to a method for testing the transmitting function of an ultrashort wave radio station. Background technique [0002] The main function of the ultrashort wave radio station is to realize the ultrashort wave line-of-sight communication between the driver and the ground command station or between the aircraft and the aircraft in the air. As far as the existing production technology is concerned, when the power-on inspection of the system is performed, the working method of the airborne finished product can only be simulated by means of short circuit, such as frequency data bus, audio analog information and radio frequency analog information, etc. The operation method is complicated and It takes a long time, and it may also cause burnout of the parts on the machine due to incorrect short-circuit operation, which poses a great safety hazard. Contents of the invention [0003] Purpose of the prese...
