Embodiment Construction

[0039] The marine facsimile weather map receiving and processing equipment based on electronic chart and radio software technology has completely changed the technical principle of the previous weather facsimile receiver.

[0040] 1. Software modem. Radio fax signals can be received without any AD conversion hardware, so the device can be connected to desktop PCs, notebook computers and PDAs at any time. No matter where they are, as long as the radio signal can be received, these machines directly receive weather faxes and weather maps.

[0041] 2. In the process of receiving faxed weather maps, it is completely automated and unattended. The software will receive all weather maps that need to be received according to the pre-set receiving table, and automatically adjust the receiving frequency at any time to track the best signal to ensure Image quality.

[0042] 3. The received image undergoes complex graphics processing by the computer, including noise removal, rotation, m...

Abstract

The invention relates to a ship weather fax device based on electric sea diagram and software wireless technique, wherein it can be used in the place supporting wireless signal. And it can avoid any AD converter to receive the wireless fax signal; therefore, the device can be connected to table PC, notebook computer, etc. And it can realize automaton and unmanned operation, to adjust receiving frequency, track best signal, etc, while it can display received diagram on electric sea diagram via vector, to analyze and predict weather.

Description

1. Technical field [0001] The invention belongs to the field of meteorology, and is a device for receiving and processing facsimile weather maps, which can be used in places where radio signals can be received, and is especially suitable for ships to use at sea. 2. Background technology [0002] Due to the well-developed nautical instruments and equipment, accidents rarely occur on ships due to equipment failure, and most of the accidents are caused by bad weather conditions. The marine weather and sea conditions are harsh, the navigation environment is complex and the conditions of the ships are limited, coupled with the negligence and mistakes of seafarers, frequent maritime accidents often cause heavy losses of life and property at sea and serious pollution of the marine environment. Maritime accidents are usually divided into collision, wave damage, rock strike, grounding, fire, explosion, sinking, missing, etc. As far as the catastrophe occurred in the 20th century, it...
