Abstract

The invention discloses an automatic test system and a test method for a Beidou satellite emergency radio beacon. The testing system comprises a base, a power mechanism is arranged in the middle of the base, a conveying mechanism is arranged on the power mechanism, and a first station, a second station, a third station, a fourth station, a fifth station and a sixth station are arranged on the base and located on the outer side of the conveying mechanism in the anticlockwise direction; the first station is provided with a second manipulator, the second station is provided with an underwater starting test device, the third station is provided with a repetitive manual starting and recovery test device, the fourth station is provided with a carrier suppression test device, the fifth station is provided with a frequency stability test device, and the sixth station is provided with a first manipulator. A master control system is arranged between the first station and the sixth station; a to-be-detected position indicating mark storage box is arranged on one side of the second manipulator on the base, and an unqualified position indicating mark storage box and a qualified position indicating mark storage box are respectively arranged on two sides of the first manipulator on the base.

Description

technical field [0001] The invention belongs to the technical field of radio navigation, and in particular relates to an automatic test device and a test method for Beidou satellite emergency radio position-indicating beacons. Background technique [0002] Beidou satellite emergency radio position-indicating beacon is a device that can transmit radio signals. It plays a vital role in the rescue of a ship or crew in distress. Therefore, Beidou satellite emergency radio position-indicating beacons should be able to be turned on normally in emergency situations, and the signals sent should have strong stability and consistency. Therefore, it is necessary to perform manual activation, underwater activation and frequency stability tests on the Beidou satellite emergency radio position indicator. [0003] The national standard "GB14391-2021: Performance Requirements for Satellite Emergency Radio Position Indication Beacons" stipulates that the satellite emergency radio position ...
