Embodiment
As shown in Figure 1, the utility model device mainly comprises wireless communication module, filtering module and data processing module.
Wireless communication module is as carrying out the passage of transfer of data with communication equipment and the Internet, with the transfer of data of short message instruction therebetween or internet information.Wherein, can communicate by Transmission Control Protocol, udp protocol or short message between wireless communication module and communication equipment and the Internet.
Specifically, can be the gsm module of using second generation mobile communication technology, second generation mobile communication develop one of gsm module in the CDMA module of the GPRS module of transition (the 2.5th third-generation mobile communication technology) and 3G (Third Generation) Moblie technology and combination of GPRS module, gsm module and CDMA module to 3G (Third Generation) Moblie to wireless communication module.
Filtering module receives short message instruction or the internet information that passes over from wireless communication module, it carries out filter analysis to above-mentioned information source then, if the described information source that analysis draws is the legal information source, then described information source is transferred to data processing module, if analyzing the described information source that draws is the invalid information source, then the invalid information source is transferred out by wireless communication module.
Wherein, filtering module available microprocessors, data signal processor, complex programmable device and any one realization of application-specific integrated circuit (ASIC).
Data processing module is encoded to described information source, unpacks, and package after handling transfers out described information source.
Wherein data processing module available microprocessors, coder/decoder, data signal processor, complex programmable device and any one realization of application-specific integrated circuit (ASIC).
More than concise and to the point description the function of each module in the utility model information filtering device, below the idiographic flow of further realization information filtering of the present utility model.
As shown in Figure 2, information source is transferred to filtering module by wireless communication module, and described information source comprises: short message instruction or internet information; Filtering module at first carries out address, the source filter analysis of described information source, whether the address, source of judging described information source is assigned address, if not assigned address, then by wireless communication module the invalid information source is transferred out, if assigned address, filtering module carries out filter analysis to the content information of described information source again, judge whether safety of its content, if non-vital data then still transfers out the invalid information source by wireless communication module, if content safety
Information source, then filtering module is transferred to data processing module with described information source, and data processing module is encoded to described information source, unpacks, and package after handling transfers out described information source.
