Abstract

The present invention belongs to the technical field of short-wave communication equipment application, and discloses a system and a method for detection of automatic antenna tuner network faults. Thesystem comprises a PC upper computer, a control unit, an impedance detection unit and an antenna tuner network unit. The PC upper computer is in serial communication with a debugging port of the control unit through a RS232 serial port, a first control signal output end on the control unit is connected with a control signal input end of the impedance detection unit, a second control signal outputend on the control unit is connected with a control signal input end of the antenna tuner network unit, an impedance detection end of the impedance detection unit is in bidirectional connection withan impedance detection end of the antenna tuner network unit, and a detection signal output end of the impedance detection unit is connected with a detection signal input end of the control unit. Thesystem and the method for detection of automatic antenna tuner network faults can automatically complete online detection of faults of the antenna tuner network unit to avoid repeat dismounting and mounting of the antenna tuner and network devices in the antenna tuner.

Description

technical field [0001] The invention belongs to the technical field of application of short-wave communication equipment, and in particular relates to a system and method for detecting network faults of automatic antenna tuners. Background technique [0002] The automatic antenna tuner (hereinafter referred to as the antenna tuner) is a device located between the short-wave transceiver and the antenna, which is used to match the antenna impedance to around 50 ohms, so as to maximize the transmission efficiency of the short-wave system. The system composed of the tuner and the antenna is called the antenna feed system. [0003] For narrowband antennas, the impedance matching between the transmitter and the antenna is artificially realized through the antenna adjustment, so as to reduce the VSWR (Voltage Standing Wave Ratio) and achieve the maximum efficiency of transmitting signals into the air. As the power of the short-wave communication system continues to increase, the p...
