Think the equipment such as ammeter.
The process of processing initial data includes: to carry out specification adaptation and the conversion (data required according to unified energy models
Initial data is adapted to and is converted to the type for the data format that energy cloud platform can be handled, energy according to certain rule by format
The format that source cloud platform handles data is typically all fixed, it is only necessary to be adapted to and be converted to the data format of the fixation just
Row), (refer to, with multi-energy data, such as to need to run electricity, then to original in initial data for ETL data cleansing
Data in data in addition to multi-energy data needed for energy cloud platform such as electricity data require to be purged), it obtains everywhere
Standardization (meeting the data format standard of unified energy models) ripe data after reason.
In Fig. 2, the processing data obtained via energy cloud platform 40 are finally that needs are corresponding by energy cloud platform 40
Cloud node 22 is sent to energy cloud platform software systems, the software systems be then for being further processed to the processing data,
Such as generate circuit electricity report, operation report, period daily sheet etc..
Mist node 23 based on edge calculations and the mist node 24 based on edge calculations be then it is corresponding with mist node host 30,

Edge calculations system provided in an embodiment of the present invention based on mist node, compared with prior art (Fig. 3), in Fig. 3
Middle energy cloud platform software systems 31, cloud node 32 and from the energy resource systems such as distributed photovoltaic, wind energy, biological energy source 35 and 36 acquire
The equipment of the energy forms, and acquisition of the energy collection device to energy datum is directly controlled by cloud node 32, because a large amount of acquisition layers (are adopted
Collect equipment) data are passed toward cloud center, each channel occupies Internet resources, it is easy to cause network blockage, therefore cannot be quick
Access.And the edge calculations system provided in an embodiment of the present invention based on mist node, it can be by edge calculations part and energy cloud
Platform calculating section function separates, and effectively solves the access of mass data fast network and concurrent access problem.
The quantity of the internet of things equipment of energy field is many in Fig. 1, the Internet of Things of cloud computing application and energy field
General character is that number of devices is more, and distribution is wide.It is corresponding below that there are two types of Internet of Things and cloud computing frameworks.
The first is identical with most cloud computing framework, is centralized cloud computing model.All internet-of-things terminals are data
Energy cloud platform is uniformly uploaded to, data acquisition, storage and analysis processing are uniformly carried out by energy cloud platform.This framework is suitble to
In the occasion not high to real-time response, such as meter reading application.Meter reading can be completed in 15 minutes or even 1 hour, 1 day,
The application of energy cloud platform is mostly based on offline on-line analysis application (OLAP) and statistical analysis.
But the application high for requirement of real-time, above-mentioned framework are not obviously able to satisfy performance requirement.Such as intelligence
O&M business needs to realize electrical equipment real time on-line monitoring, is analyzed by the data of acquisition, determines failure, and push
Alarm, is real-time, quasi real time Internet of Things application of a standard.It is flat that energy cloud is transferred data to from internet of things data acquisition node
Platform, then data analysis and judgement are carried out by energy cloud platform, push alarm, processing links are more, and network has delay, real-time
Hardly result in guarantee.
Naturally it is considered that using the framework of " edge calculations ", " fringe node " is disposed in the place close to data source,
Thus calculate node data acquisition, data processing and accident analysis on the spot is put down energy cloud is sent in treated result
Platform carries out unified management and alarm pushing by energy cloud platform.In this way, the calculating work of centralized energy cloud platform is by dispersedly
Be assigned to each fringe node, by distributed computing realize in real time, fast and efficiently user response.
In this case, edge calculations (Edge Computing) are applied and are given birth to, its core concept will exactly count
According to storage, transmission, calculating and safety give mist node host 30 and handle.Certainly the terminal before occurring with cloud computing calculates not
Together, edge calculations are not to say that energy collection device 10 to be allowed oneself is responsible for all calculating, but from energy collection device 10
Closer place deployment mist node host 30, communicating between energy collection device 10 and mist node host 30 can be there are many form
(for example, 485 communications, TCP communication, ZIGBEE, NB-IoT etc.) are can solve in this way because of a large amount of acquisition layers (acquisition equipment) past cloud
Center passes data, and each channel occupies Internet resources, it is easy to cause network blockage, to generate network delay, and cause
The problem of loss of data.The interactive calculating of a large amount of needs in real time (such as the data of acquisition are summarized, calculate, are analyzed,
It will such as: total electric degree, total active power, total reactive power, out-of-limit calculating) be completed in fringe node, at some needs centralizations
The calculating of reason then continues to transfer to large-scale cloud computing center, wants centralized cloud computing center if big data is excavated, learnt on a large scale
It could complete, edge calculations are shared out the work and helped one another with cloud computing, to meet the calculating demand of IoT epoch explosion type.
Also it is believed that if energy website has had communication processor, if can directly upper cloud；Again by mist node
The more equipment of upper cloud, increase workload instead, increase cost.
Firstly, whether will increase from workload from the perspective of engineering construction and platform maintenance.From Technical Architecture,
It is complete as one, it can safeguard, expansible platform, be necessarily required to an access layer to be adapted to the data of isomery acquisition system
System, such as photovoltaic, wind-powered electricity generation, intelligent building, customer substation.For energy cloud platform, as long as in face of unified access layer
It can be with.If also to construct such a access layer beyond the clouds using the directly upper cloud of communication processor.Access layer nothing more than
Work is realized in mist node, is still realized beyond the clouds.It can be seen that accessing as workload is almost, mist is not used
Node just will increase workload.
Secondly, the directly upper cloud of communication processor will be a cost savings? if scene does not have communication processor, increase reliable
, the cost of qualified communication processor and mist node it is suitable.Such as the existing communication processor in scene, specifications and models, communication interface,
Specification is multifarious, and that be unified is linked into energy cloud platform, must also provide or the access converting unit of configuration standard.
And this hardware cost, construction cost and mist node for accessing converting unit are about the same.If converted without standard interface
The communication processor of unit, the various isomeries in scene directly passes through cloud in wireless transparent transmission equipment, then needs to carry out specification beyond the clouds to connect
Enter adaptation, higher to personnel requirement, the difficulty for accessing debugging is also higher, even if the cost of labor for increasing the 1-2 man day is just complete
It is worth the cost of a mist node host entirely.And wireless transparent transmission equipment, such as 4G router, RS485 turns 4G module, itself
Need cost.
Finally, communication processor can not be competent at the requirement of edge calculations.It is had seen that by the analysis of front, it can source interconnection
Net platform is inevitable choice using edge calculations Technical Architecture, and mist node is also energy Internet application total solution must
Indispensable a part.And communication processor is still an internet of things data acquisition node, from overall architecture and one
Ammeter only summarizes the data of more muti-piece table without what difference.Higher want can of course be made to communication processor
It asks, can can have energy device model by the unified configuration of cloud node and monitoring with distributed storage, can be distributed
Formula calculates, can be with remote deployment application etc., and here it is a mist nodes for that.
Edge calculations part and cloud center calculation partial function are separated in the embodiment of the present invention 1；And in the prior art
In, then it is that all acquisition equipment acquire " raw data " and are transferred to the processing of energy cloud platform, after being uniformly processed by energy cloud platform
It realizes various businesses, not only needs a large amount of invalid datas of high speed bandwidth for transmission, but also also bring great burden to energy cloud platform
(as shown in Figure 3).Final result is that processing cost is high, and processing time period is long, inefficiency, and real-time response is poor.Compared to existing
There is technology, can effectively solve the access of mass data fast network and concurrent access problem, and can be right within the time of Millisecond
The collected initial data of energy resource system is handled, and completes monitor task at the first time.
In the embodiment of the present invention 1, mist node energy models are that be sent to energy cloud platform 40 by energy cloud platform 40 right
The mist node host 30 answered, and mist node energy models access energy cloud platform 40, or replacement in mist node host 30 for the first time
