In addition, image recognition, refers to and utilizes computing machine to process image, analyze and understand, to identify the target of various different mode and the technology to picture.During general industry uses, adopt industrial camera pictures taken, and then do further identifying processing according to picture ash jump.Image recognition can based on the principal character of image.Each image has his feature, and as alphabetical A has a point, P has a circle and there is individual acute angle etc. at the center of Y.The research dynamic to eye during image recognition shows, sight line always concentrates in the principal character of image, and namely concentrate on the place of the maximum or contour direction flip-flop of image outline curvature, the quantity of information in these places is maximum.And the scanning route of eyes also always forwards to another feature from a feature successively.As can be seen here, in image recognition processes, perceptual mechanism must get rid of the redundant information of input, extracts crucial information out.
In addition, GPRS, the i.e. abbreviation of general packet radio service technology (General Packet Radio Service), he be gsm mobile telephone user can a kind of mobile data services.GPRS can say it is the continuity of GSM.GPRS, with the continuous mode in channel transmission was different in the past, is to transmit with package (Packet) formula, and the expense that therefore user bears calculates with its data transmission unit, and its whole channel of non-usage, in theory inexpensively.The transfer rate of GPRS can be promoted to 56 even 114Kbps.GPRS is often described as " 2.5G ", and that is this technology is positioned between the second generation (2G) and the third generation (3G) mobile communication technology.
GPRS, by utilizing untapped TDMA channel in GSM network, provides the data transmission of middling speed.GPRS breaches GSM net can only provide the Circuit-switched mode of thinking, only realize packet switching by increasing corresponding functional entity and carrying out part transformation to existing base station system, the input of this transformation is also little comparatively speaking, but the user data rate obtained is considerable.And, because no longer need the intermediary's conv required for existing wireless application, all can be easily more convenient so connect and transmit.So, user both can connect to the internet, and participated in the interactive communication such as video conference, and on same video communication network the user of (VRN), even can without the need to by dialling up on the telephone, and continue connected to the network.
The signalling methods of GPRS packet switching is in the signalling methods of packet switching, and data are divided into the bag (grouping) of certain length, has a packets headers (address mark wherein indicates this grouping and mails to where) before each bag.Data do not need to allocate channel in advance before transmitting, and connect.But when each data packet arrives, according to the information (as destination address) in datagram header, this datagram sends by the channel resource that searching one is available temporarily.In this load mode, that does not fix between the transmission of data and take over party's cochannel takies relation, and channel resource can be regarded as shares use by all users.
Adopt intelligent cable car speed control apparatus of the present invention, for existing cable car control system lack of wisdom speeds control mechanism, lack the technical matters of tension force Real-Time Monitoring mechanism, by image acquisition and recognition technology, a cable car queuing visitor that waits is gathered to image and carries out the identification of visitor's number, based on visitor's number, the parameters such as cable car maximum capacity and cable car spacing control cable car running velocity in real time, on carrier cable, increase cable tension detection means simultaneously, with the emergency braking when cable tension is too low, thus improve the intelligent level of cable car control system on the whole.
Be understandable that, although the present invention with preferred embodiment disclose as above, but above-described embodiment and be not used to limit the present invention.For any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the technology contents of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
