Background technology
Used cloud in the Internet widely, mainly comprised three kinds of different types, software is namely served SaaS, and platform is namely served PaaS, and architecture is namely served IaaS.Wherein PaaS provides the complete or application development partly that the user can visit, and SaaS then provides the complete application program that can directly use, such as passing through Internet management enterprise resource.And the cloud among the IaaS is the most key with Mass Data Management technology, mass data distributed store technology, Intel Virtualization Technology, cloud computing platform administrative skill.Wherein Mass Data Management technology and distributed storage technology are the important component parts that data are handled, cloud computing need be handled, analyze data that distribute, magnanimity, therefore, data management technique must be managed lot of data efficiently, needs the mode of redundant storage to guarantee the reliability of data in addition.Widely used data-storage system is that the GFS of Google and the increasing income of GFS of Hadoop team develops are realized HDFS in the cloud computing system.
The safety in production of industrial and mining enterprises is in the production run of reality, must there be mass data (as various safety in production standards, data monitored, educational training knowledge etc.) to need to handle, the cloud service platform adopts the Distributed Calculation storage mode, with distribution of computation tasks parallel processing to many machines, improve arithmetic speed with this.To the keep the safety in production data message of enterprise practical production accumulation of cloud platform carries out unified management and storage, for functions such as prediction based on data, abnormality detection are provided in the production process, realizes safety and production.
The data acquisition function of tradition industrial and mining enterprises and concrete logic judging function are in conjunction with tight, usually finished by comparatively single hardware device, therefore, finishing different functions just needs configuration different equipment or system, and there are separately independently data acquisition unit in the equipment of these difference in functionalitys or system.Each data acquisition exists that overlapping collection, utilance are not high, data and problems such as the information content is inconsistent, time disunity, formed " information island " that, horizontal system many with vertical level mostly is principal character, restricted further fusion and the application of information, the repeated acquisition of data and information and repetition transmission process certainly will cause the waste of various resources.Instrument in most of industrial and mining enterprises is divided into three classes: the protection class, and the observing and controlling class, the metering class, they have the data acquisition and processing (DAP) unit of oneself, can be connected with monitoring and display system, are used for underlying parameter and measure.
Based on the video monitoring of cloud platform can be in real time, image, reflect the state of monitored object truly, be convenient to storage, can improve the efficiency of management and automatization level, pinpoint the problems when being convenient to urgency and analysis afterwards.Video camera is one of core building block in the video monitoring system, widely used video camera is analog signal output under coal mine at present, be divided into analog electrical signal output and analog optical signal output dual mode, the shortcoming that has transmission range weak point, poor signal quality, is subject to disturb for the video camera of analog electrical signal output; Video camera for analog optical signal output needs past aboveground laying optical cable point-to-pointly, has the shortcoming that networking model is single, quantities is big, networking cost is high.
Summary of the invention
