Distress signal receiving module and decoding method thereof

Abstract

The invention relates to a distress signal receiving module and a decoding method thereof. The distress signal receiving module and the decoding method thereof can solve the problems that the prior art is influenced greatly by severe environments, and is poor in quality and performance. According to the technical scheme, the distress signal receiving module comprises a stabilizing power supply circuit for supplying power, a receiving antenna, a receiving module controller, a bus interchanger, a protector circuit, a filter circuit, a mixed frequency amplifying circuit, a modem circuit, a receiving module first memorizer, a USB integrated circuit and a receiving module second memorizer. The receiving module controller is connected with a processor module through the bus interchanger. The filter circuit is connected with the input end of the filter circuit through the protector circuit. The output end of the filter circuit is connected with the input end of the mixed frequency amplifying circuit. The control end of the mixed frequency amplifying circuit is connected with the receiving module controller. The output end of the mixed frequency amplifying circuit is connected with the input end of the modem circuit. The output end of the modem circuit is connected with the receiving module controller. The distress signal receiving module is good in quality and performance.

Description

technical field [0001] The invention relates to a signal receiving module and a decoding method thereof, in particular to a distress signal receiving module installed on an embedded search and rescue chartplotter and a decoding method thereof. Background technique [0002] The requirements for search and rescue chartplotter products are: the performance and quality must meet the electronic chart system standards issued by the domestic maritime department, the volume should be small and portable, the operation is easy to use, easy to master, and it is suitable for relevant personnel such as maritime operations.
