Weather fax image receiving and processing device for ship and receiving and processing method

Abstract

The invention provides a weather facsimile image receiving and processing device for a ship and a receiving and processing method. A front end control and data acquisition processor is connected with an image receiving front end in two ways and connected with a low-phase noise local oscillator in one way; an embedded web server is connected with an image storing unit, Ethernet, FLASH and an SDRAM (Synchronous Dynamic Random Access Memory) in two ways and connected with the front end control and data acquisition processor by a double-port Ram and external interrupt in two ways; and an RJ45 network interface is connected with the Ethernet in two ways. The additional embedded web server, a high-capacity storage card and an Ethernet communication unit are added by combining the development trend of embedded equipment on the basis of utilizing the receiving part of the traditional weather facsimile receiving equipment. A paper printing way is replaced by the digital storage of weather facsimile information, and a network port of the receiving equipment is connected with a network port of a personal computer of a subscriber by the Ethernet.

Description

technical field [0001] The invention relates to an image receiving device, in particular to a wireless weather facsimile image receiving and processing device suitable for use on ocean ships. Background technique [0002] It is very inconvenient for ships to obtain meteorological information when navigating at sea. Therefore, severe weather and sea conditions often pose a serious threat to the safe navigation of ships and are the main source of marine accidents. For a long time, in order to ensure the safety of ships going to sea, many countries have adopted free wireless fax to broadcast weather forecast. By establishing a transmitting station on land, texts, pictures, etc. are scanned and photoelectrically converted, and then sent out through wireless channels, so that the crew can obtain weather forecast information in time. The World Meteorological Organization (WMO, World Meteorological Organization) divides the global service network of transmitting stations into six ...

AI Technical Summary

Problems solved by technology

The current meteorological fax receiving equipment includes receiving, control, printing and power supply parts. The thermal print head is very bulky, and the power supply power is also increased. The integration of the whole equipment becomes lower and the portability becomes worse.

[0008] 2. The existing meteorological fax receiving equipment adopts the paper printing method, and manually controls whether to print

When the image is not good, it is very easy to cause paper waste, and it is very troublesome to save, backup and search for drawings

[0009] 3. Operate machinery, the operation process is complicated

[0010] 4. Single function, unable to share data with other systems

Meteorological fax images contain a wealth of information sources. According to the current paper printing method, meteorological fax images need professionals to analyze, and paper images cannot meet the needs of electronic data sharing.
