Build the monitoring device of above-mentioned net cast.
In addition, the abbreviation of general packet radio service technology (General Packet Radio Service), he is GSM
A kind of available mobile data services of mobile phone user.GPRS can say be GSM continuity.GPRS is continuously passed with previous in channel
Defeated mode is different, is transmitted, therefore the expense that user is born is with its data transmission list with package (Packet) formula
Position calculates, not using its entire channel, theoretically inexpensively.The transmission rate of GPRS can be promoted to 56 even 114Kbps.
GPRS is often described as " 2.5G ", that is to say, that this technology is located at the second generation (2G) and the third generation (3G) is mobile
Between mechanics of communication.He provides the data transfer of middling speed by using TDMA channels not used in GSM network.GPRS is broken through
GSM nets can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Part transformation is carried out to realize packet switch, the input of this transformation is comparatively and little, but obtained user data rate
It is considerable.Moreover, because no longer needing the required intermediary's converter of existing wireless application, connection and transmission all can
It is more convenient easy.In this way, user can both connect to the internet, the interactive communications such as video conference are participated in, and in same video signal net
The user of (VRN) on network, it might even be possible to without by dialling up on the telephone, and continue and network connection.
For the communication mode of GPRS packet switches in the communication mode of packet switch, data are divided into the packet of certain length
(grouping), each wrap before there are one packets headers (address mark therein indicates the grouping is sent to where).Data transmit it
Before do not need to allocate in advance channel, establish connection.But when each data packet reaches, the information in datagram header
(such as destination address) finds an available channel resource and sends the datagram temporarily.In this transmission mode, number
According to the side's of sending and receiving cochannel between there is no fixed occupancy relationship, channel resource can be regarded as being total to by all users
Enjoy use.Since data service all shows a kind of paroxysmal business characteristic in most cases, to channel width
Changes in demand is larger, therefore will preferably utilize channel resource using packet mode progress data transmission.Such as one into
The user of row WWW browsings, the most of the time is in browse state, and really the time for data transmission only accounts for very little ratio.
In this case according to the mode of fixed busy channel, it will cause the larger wasting of resources.
The monitoring device and monitoring method of net cast using the present invention, for net cast safety in the prior art
Can be low the technical issues of, by increasing multiple images processing equipment and network communication apparatus around net cast equipment, builds
Personnel's authentication scheme of the high-precision that is based on recognition of face, unauthorized personnel is prevented except access rights.
It is understood that although the present invention has been disclosed in the preferred embodiments as above, above-described embodiment not to
Limit the present invention.For any those skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications are all made to technical solution of the present invention using the technology contents of the disclosure above or are revised as
With the equivalent embodiment of variation.Therefore, every content without departing from technical solution of the present invention, technical spirit pair according to the present invention
Any simple modifications, equivalents, and modifications made for any of the above embodiments still fall within the range of technical solution of the present invention protection
It is interior.
