Description
Technical field
The utility model relates to communication technical field, relates in particular to a kind of modulator-demodular unit of alarm automatically of realizing.
Background technology
Along with the development of technology and people require higher and better quality of life, portable computer universal more and more widely, and be that the personage of Work tool also gets more and more with the portable computer.On the other hand, the development of mobile communication is also maked rapid progress, and carries out the transition to 3G from 2G, and moves standard also in formulating and developing as more higher leveled 4G.And the development purpose of mobile communication technology is to provide better communication facilitation and better amusement enjoyment to general public.Therefore, in order to satisfy often to go on business is the demand that the personage of work pattern and liking experiences the personage of facility that new technology brings and enjoyment, now with the vehicular data service of mobile communication technology also in each operator in the whole world widelys popularize, and slowly upgraded to one of main method that operator makes a profit.Especially 3G mobile communication, main function just provides higher wireless bandwidth and wireless Internet access speed, therefore in order to satisfy above-mentioned personage's amusement demand, modem is subjected to paying close attention to widely and using as a kind of carrier of mobile data services day by day.Directly (one of general usb data line has two USB interface to MODEM by the usb data line, in the time of in order to undercurrent, two USB interface are all inserted computer, increase power supply) insert USB interface and be linked into PC computer or notebook computer (in this article, for setting forth conveniently the unified PC computer that becomes), power by the USB interface transceive data of PC computer with to MODEM, satisfy the requirement of MODEM work, and do not need extra battery or charging equipment.
On the other hand, the development of TV tech and the raising of people's living standard, and the change of people life style, portable type electronic product is in vogue, has also made and has supported the mobile TV of hand-held mobile device to be able to fast development.Along with the notion of mobile TV is also increasingly mature, also a hundred flowers blossom for the mobile TV technology of various standards and standard, uses now comparatively ripe and DVB-H, DVB-T etc. are arranged comparatively widely.National governments actively promote digital video broadcasting work invariably, quicken its universal time-histories.The General Bureau of Radio, Film and Television and the Ministry of Information Industry of China have also all formulated the mobile TV standard of oneself.
For the MODEM that supports mobile TV, general still the employing only uses the USB mouth that links to each other with the PC computer to power, and do not use battery or other external power supply.Televise and the online upload, when downloading, because the big load operation of CPU, and the DSP on the base band (Digital Signal Processing, digital signal processing) and USB interface carry out data processing in enormous quantities, causes average current to strengthen accordingly.And MODEM can support to televise simultaneously, the uploading and downloading of function of surfing the Net, and therefore, when concurrent, the electric current that causes USB interface to provide possibly can not satisfy the current requirements of MODEM side.At this moment, if do not take measures, can cause MODEM frequently to fall net, the more serious generation that causes notebook deadlock phenomenon because of the electricity shortage of notebook USB interface.Therefore, need this moment to insert another USB interface of MODEM data line to the PC computer.
On the other hand, numerous types such as notebook and desktop computer computer have experiment to show under identical MODEM load at present, there is marked difference in the USB interface power supply of each notebook computer, the load capacity that has is strong, shows that the electric current of output is big, near or surpass the supply standard setting of USB; The load capacity that has is poor, shows as output current and is lower than USB interface supply standard setting.The restricted characteristics that are based on USB interface class consumption electronic product of powering.
For the limited situation of this power supply, adopt the method for MODEM side implementation current limliting is taked overcurrent protection now.As Application No. 20040100748, name is called: Adaptive current limiter forwireless MODEM, this patent detects electric current by current-limiting apparatus, dynamically adjusts the current-limiting points of power amplifier load according to detected current conditions.In addition Chinese patent application numbers 200610112254.8, and name is called: data card self-adapting power supply method and system, this patent realize current limliting and to the adaptation power supply of various notebook computers.Promptly generally can adopt now the method for this current limliting to avoid the load current of MODEM excessive and cause frequently restarting or notebook crashes, but this equally also can limit the use of some function among the MODEM.Therefore if take current limiting measures, can cause some function cisco unity malfunction of MODEM, influence user's actual experience.
