Fax shielding device

Abstract

The invention provides a fax shielding device which solves the problem that a fax machine cannot identify junk faxes in the prior art. The fax shielding device comprises a communication interface, a first buffer, a storer, a DSP (digital signal processor) and a printer, wherein the communication interface is connected to a telephone connection port; the first buffer is connected to the communication interface and used for buffering fax data; the storer stores preset fax numbers and keywords; the DSP is connected to the first buffer and the storer and is used for receiving the fax data, comparing the fax data with the fax numbers and the keywords in the storer through a comparator, shielding the fax data when match items are included, and transmitting the fax data to a second buffer when match items are not included; and the printer is connected to the second buffer and used for printing the fax data.

Description

technical field [0001] The invention relates to the communication field, in particular to a facsimile machine. Background technique [0002] Fax machines are necessary communication equipment in the office field, but they are often disturbed by many junk faxes, such as advertisements, which waste a lot of power and paper. Contents of the invention [0003] The invention provides a facsimile shielding device, which solves the problem that facsimile machines cannot identify junk faxes in the prior art. [0004] Technical scheme of the present invention is realized like this: [0005] A fax shielding device, comprising: a communication interface connected to a telephone connection port; a first buffer connected to the communication interface to buffer fax data; a memory storing preset fax numbers and keywords; DSP processing The device is connected to the first buffer and the memory, receives the fax data, and compares it with the fax number and keywords in the memory throu...
