Product description:
In recent years, our fishery water safety accidents, while fishing vessels operating or distress , fishing is fishing and land communication , the exchange of information between vessels only way . Country chose 14 shortwave shore station to update equipment construction ( maximum transmit power 500W), as a national shore station , a 24 -hour listening watch , accompanied by coastal fisheries authorities at all levels , fishing enterprises , fishing and other settings hundreds shore station , for our more than 60,000 vessels equipped with HF SSB radio -sea fishing vessels to provide secure communications , but also bear the marine meteorological forecasts , distress alert , directing rescue , everyday communications and other tasks. Since 2005 , China's investment of nearly 40 million yuan started integrating existing marine fishery communications resources , establish a unified national marine fisheries secure communications network. This network includes a secure communications network of marine fisheries shortwave , FM ( offshore ) security and emergency communications network fishery , fishing vessels and marine fisheries vessel position monitoring network public mobile communications network ( referred to as " quadruple play " ) , set fishing safety and fisheries administration and management communication , production and life fishermen communications services in one, in the " safe fishing " building plays an important role in safeguarding .
The company developed the "far sea ship information services and monitoring command system " will simulate sea vessels HF SSB radio direct upgrade for remote data communication terminal capable of receiving from the shore-based marine meteorological radio (1kW) or high-power marine shortwave radio ( can be more than 10kW) sent Haiqing , meteorology , marine and other information , and through the ship SSB radio report their location ( the original is GPS, and are being gradually replaced with our own Beidou ) and other information ( such as monitoring the picture, sailing record text, etc. ) , from the technical support and information content on marine meteorological radio stations provide more effective marine fisheries meteorological information and other value-added services , from the management to improve the waters of the South China Sea fishing boats and other vessels tracking capability from industries to promote the emerging marine information services.
The system has experienced marine meteorological radio Maoming, Guangdong / Guangzhou Maritime HF communication radio base stations and ship sea trial more than two years , meteorological services and emergency broadcasts ( such as typhoon warning ) significantly increased the level of automation ( such as short-wave radio transmitter automatically activated stop, satellite transmission, etc. ) , in November 2012 in Guangdong Jiangmen shipment 2 150 km voyage to good effect. 2013 after the Spring Festival has voyage to 600 km away , can still communicate , but by the characteristics of HF channel constraints, sometimes the signal is not stable enough . Guangzhou Maritime Bureau in Hainan three Shashi establish shortwave receiver array in the expression of national interests, but also conducive to the implementation in line with the product .
While Equipped SSB shortwave radio seas fishing vessels , there are some with hardware modem (MODEM), but only the highest rate of 2400bps, performance is far and our defense conversion compared to products . According to the classification of Guangdong , the more than 300 tons of fishing boats called deep can a distant sea ( not the ocean ) , such as deep-water fishing in the South China Sea about 70 000 , together with the East China Sea and the Yellow Sea, estimated the total number of the country's far out at sea fishing around 100 000 , that is, there are some distant sea vessels not equipped with SSB radio . To 100,000 in terms of far- sea fishing , configure our software products in the market capacity of 6 to 20 million, plus $ 3,000 per year per boat service charges, Guangdong Province alone 37,000 deepwater fishing can receive 110 million annually yuan in service fees, the market is huge .
