The fax image forwarding apparatus has the advantages of being simple in structure and small in volume and improving the information application efficiency and the convenience degree.
Description
Technical field
The invention belongs to meteorological telecommunication technical field, especially relate to a kind of facsimile signal retransmission unit.
Background technology
Global subdivision is six large sea areas by international maritime organization, there is corresponding platform in each sea area, the listing fixing according to it broadcasts weather facsimile 24 hours every days, the content broadcast is weather information, Wave Information, tide etc., be used to guide ship and arrange course line according to weather condition, current weather map facsimile equipment produce market many monopolize by foreign corporation, not only bulky but also function is weak, be inconvenient to use.
Summary of the invention
The object of the invention is, in order to overcome prior art deficiency, to provide a kind of facsimile signal retransmission unit, its structure is simple, and volume is little, improves using efficiency of information and comfort level.
Technical scheme of the present invention is: a kind of facsimile signal retransmission unit, comprise communication module, control module, FM module, D/A modular converter, filtration module and key-press module, described communication module, control module, FM module, D/A modular converter are connected successively with filtration module, and described key-press module is connected with control module.
Further, described control module connects host computer by communication module, and described communication module comprises network interface and serial line interface.
Further, described key-press module comprises power transfer module switch and reset key, and described control module is connected with power transfer module by power transfer module switch.
Further, described filtration module adopts low pass filter.
Further, described control module adopts ARM9 chip.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, no matter wherever, as long as when can receive radio signal, just can receive the Weather fax image that this transponder just directly forwards, achieve Weather fax image automation to send, and the quality of assured forwarding image.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
Shown in structural representation as of the present invention in Fig. 1, the invention provides a kind of facsimile signal retransmission unit, comprise communication module, control module, FM module, D/A modular converter, filtration module and key-press module, described communication module, control module, FM module, D/A modular converter are connected successively with filtration module, and described key-press module is connected with control module.
Described control module connects host computer by communication module, and described communication module comprises network interface and serial line interface.
Described key-press module comprises power transfer module switch and reset key, and described control module is connected with power transfer module by power transfer module switch.Described filtration module adopts low pass filter.Described control module adopts ARM9 chip.
The course of work of this example: facsimile signal retransmission unit provided by the invention, for realizing by Weather fax image by the conversion of digitized pixel to audio signal, conversion comprises two parts: 1, weather facsimile protocol generation; 2, audio signal conversion.Transponder audio signal transfer process is, transponder is connected host computer by the network interface of communication module with serial line interface, wherein network interface is for transmitting meteorological causes shape, form is jpeg, png etc., serial line interface is used for instruction interaction, starting, sending end, send parameter, abnormal conditions information etc. as sent.After transponder receives image, be converted into bianry image formatted file, audio signal is converted to further again by FM module, digital signal is converted to analog signal through D/A modular converter, after filtering after module filtered, externally output to short-wave transmitter by audio signal interface, after being modulated by short-wave transmitter, send in shortwave mode.
Control module, using ARM9 as the control core of system, is responsible for communicating with host computer, and the image of JPG, PNG form simultaneously sent by host computer converts bmp form bitmap file to, and sends to FM module.
FM module mainly completes FSK frequency modulation function, by the sine wave signal being converted to corresponding signal frequency by bianry image signal, and sends to D/A modular converter according to Weather fax image form.
The digital signal that D/A modular converter is used for FM module sends converts analog signal to, and filtration module is used for carrying out filtering to analog signal, exports eventually through audio interface.
Key-press module comprises power transfer module switch and reset key.
Power transfer module uses AC-DC power transfer module, is input as AC220V, output+5V ,+3.3V.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
