Data acquisition and the system that gathers shunting based on cloud computing system
Technical field
The utility model relates to the data acquisition system of computer network, is specially a kind of data acquisition and the system that gathers shunting based on cloud computing system.
Background technology
Cloud computing (cloud computing), distributed computing technology a kind of, the concept that it is the most basic, be to see through network huge computing program is split into numerous less subprogram automatically, transfer to the bulky systems that the multi-section server forms again and after search, computational analysis, result is returned to the user.See through this technology, Internet Service Provider can be within the several seconds, reaches and handles number in necessarily even hundred million information, reaches and the network service of " supercomputer " same powerful usefulness.
Data acquisition refers to obtain data from a system or terminal, and enters the process of another system or terminal according to certain form storage.Data acquisition in the computer science can be carried out differences according to terminal and system different and divides, and wherein a kind of is exactly image data from the database of the dispersion of isomery, carries out unified data management and storage then.In mobile search, need to gather a large amount of user data and mobile environment data.Mobile data have two main features, decentralized and magnanimity.The mobile data of decentralized finger are present in the various heterogeneous databases of operator, and are scattered in each data center.Magnanimity refers to that mobile subscriber's consumption record and wireless environment data all can present the characteristics of magnanimity owing to the accumulation of time and user's growth.
The data that each node is gathered, can reach the purpose that separate data is integrated by the definition uniform data format, cloud computing sees through network huge computing program is split into numerous less subprogram automatically, transfer to bulky systems that the multi-section server forms again through searching, result returned after the computational analysis characteristics to the user, the mobile data of disperseing can be incorporated on the uniform platform and be used, this is the advantage that other computation schemas can't provide.For the mass data that single node collects, cloud computing is better brought into play the disposal ability of whole system rather than the disposal ability of single node by the ultra-large and high fault-tolerant ability of oneself.
The Mesh network i.e. " wireless mesh network ", and it is a wireless multi-hop network, is by the development of adhoc network, is one of key technology that solves " last kilometer " problem.In the process of picture next generation network evolution, wireless is an indispensable technology.Wireless mesh can be communicated by letter with other network cooperating.Be the network architecture that can constantly expand dynamically, two equipment all can keep wireless interconnected arbitrarily.
Wireless Mesh netword (based on wireless mesh network) is also referred to as " multi-hop (multi-hop) " network, and it is a kind of and the diverse novel radio network technology of conventional wireless network.In traditional wireless lan (wlan), each client all visits network by a Radio Link that links to each other with AP, the user must at first visit a fixing access point (AP) if intercom mutually, and this network configuration is called as single-hop networks.And in wireless Mesh netword, any wireless device node can be simultaneously as AP and router, and each node in the network can send and receive signal, and each node can carry out direct communication with one or more peer node.
At present, though cloud computing is distributed to each computing node in the network with evaluation work, but providing of the management of result of calculation and application service still needs administrative center to bear, therefore the data channel between each node, gateway node and the administrative center in the whole network is particularly important, perhaps, the individual node fault does not influence the allomeric function of system for cloud computing, but the gateway of being responsible for being connected with administrative center breaks down, the data result that then can cause distributing calculating, handling can't gather to administrative center, and administrative center also just can't provide relevant application service.
Secondly, in sensing network, even possess self-healing ability, but the key node in the network (for example gateway node) still can make the data interaction of network obstacle occur when producing fault, causes the application of whole sensing network to be lost efficacy.
Because the range of application of sensing network is increasingly extensive, even if adopted the pretreated scheme of data, simple computing ability by transducer or sensing node self is enough to satisfy practical application far from, still need the support of large data processing center or administrative center, so the pretreated scheme of data can not solve the transfer of data obstacle that sensing network causes because of key node (for example gateway node) generation fault.
