Description
Technical field
The invention belongs to internet of things field, be related to the setting of the city Internet of Things edge calculations site based on base station with
Management method.
Background technique
(1) base station install Internet of Things edge calculations site the problem of and chance
1, region and urban infrastructure sensing equipment tool volume and diversity, non-single base station can all be covered
The intelligence of region and urban infrastructure is related to a plurality of types of sensor equipments, internet of things equipment and leads to
Letter, data fusion and application system；These sensors are segmented into two major classes.
The first kind be detect certain class urban facilities state it is whether normal, such as well lid sensor, wisdom dustbin sensor,
Street lamp fault sensor, parking stall parking sensor ... etc.；This kind of sensor simple structure, only sensing whether be, have with
Nothing does not detect his time variable；Its substantial amounts but smaller with edge calculations relationship.Second class is detecting broad sense physical quantity
The sensor changed over time, such as temperature sensor, strain gauge, strain transducer, magnitude of traffic flow sensor, water flow
Sensor, flow sensor, water level sensor, water pollution sensor, PM2.5 sensor, monitoring camera device ... etc.,
Though quantity is more not as good as the first kind, there are many type.
Second class sensor Yi Qibu can build position and be divided into two kinds again again, the first is for specific single facility (example
Such as bridge, tunnel etc.) sensor special (strain transducer, shock sensor, temperature sensor etc.) built of institute's cloth, position is solid
It is fixed, length or area also specialization.Another kind is dispersed in the sensor of each not privileged site in city, such as Traffic monitoring
Sensor, level of ground water sensor, the sensor along the setting of rain (dirt) water drainage pipeline, soil moisture content sensor, water pollution
Sensor etc..
The first sensor has specialized company's installing, acquisition data, analysis information, maintenance because position fixes, function is specific
Maintenance, problem is not counting very big.It is speciality platform that acquired data need to be transmitted to specialized company often with internet compared with what can be considered
It is analyzed, then analysis gained information transmission is supplied to client (such as supervision department), there are still data transmission for this
The problems such as traffic congestion, fault, information are cracked.If can generate point in data by edge calculations is subject to calculation processing, directly by political affairs
Mansion is supervised unit and is controlled, and is rather future developing trend.
Second of sensor gradually and is generally installed in each place in city according to the wisdom of urban operating mechanism.One
Up to ten thousand of micropolis installing, up to ten million of medium-sized city, the more than one hundred million a sensors in large size city differ.Its brand and supplier are many
More, due to lacking Its Relevant Technology Standards, there are larger differences for communication protocol, technical indicator and the functionality of different manufacturers product.
In face of the heterogeneous access of different sensing equipments and communication equipment, a kind of object that the data towards extensive information are picked, transmitted is needed
Networking middleware, with efficient, the data for acquiring sensing layer equipment in Internet of Things of safety are transferred to each user of application layer.
In addition, the data transmission of city internet of things sensors mostly using various narrowbands or ultra-narrow band (such as Zigbee, LoRa,
NB-IoT etc.) running of one of transmission mode, respective base station is different, is unable to intercommunication each other.Most of existing solutions are different
Source sensor respectively uploads to cloud with the gateway of oneself and does integrated treatment, generates judgement and decision.Even so,
For omnifarious urban operating mechanism, it is provided with after examination by every profession and trade specialized company and gives municipality, subsequent action,
It is quite numerous and disorderly that a word used in person's names, information processing etc. are adopted in maintenance, data, leads to the problem of very much.
The present invention proposes that Internet of Things edge calculations site is arranged by base station, at least aiming at the problem that second of sensor
It solves to capture with the sensing data of the base station homogeneous communications, then installs other communications kind in one's respective area additional in the calculating site
The data decoder module of class, to capture the data in the surrounding sites because of sensor needed for carrying out particular edge calculating extensively, such as
This can reduce cost.Set calculating site, which has administrative related sensor, detects wrong function, can detect failure sensing nearby
Device maintains easily and manages be packaged sensor, also builds and uses conducive to the cloth of big quantity sensor.
2, base station location is clear, and it has accomplished regional balance to data transmission
When goodbye sets Locating Type edge calculations site, first is also the largest puzzlement problem, is to build on earth
Do you wherein make it suitable? which kind of mode is either taken to select to build place, always unavoidably with the interaction of peripheral base station；Therefore, position
Very specific base station is set rather to be preferably selected；As long as the local for considering the purpose of edge calculations and its involving, selection
It is a most direct effective method really in the base station on the local side.Both it can be apt to the homogeneous communications means with surrounding sites
Calculated result can also be directed through base station transmission even only saving 0.1 millisecond every time and add up the effect of getting off just by sensor
It is very big.
(2) internet of things product business (operation) mode:
In existing internet of things product business model, there is following three Class Type:
(1) charge by service: product is exactly to service, combination of hardware software platform, carries out data analysis, and according to using
Amount charge.Such as: General Electric Apparatus Co.(U.S.A.) GE itself is to rent based on engine, and engine itself possesses many sensors,
So after engine connects net, so that it may can in conjunction with prediction and asset management platform Predix the data come from engine collection
To calculate the extent of deterioration of engine, and determine whether to replacement engine, allow company of the GE just from rental engine, become to sell early warning and
Maintenance service, when customer is more long using engine, money is paid more.
(2) charge according to dosage or effect: combination of hardware software platform is charged according to dosage or effect.Such as: insurance company
METROMILE can provide equipment and collect the services such as vehicle condition, automotive check, hypervelocity warning, and premium is calculated by practical mileage number.
(3) cross-cutting income: from original hardware and platform, new application field is transboundary arrived.Such as: automobile brand tesla
From production electric vehicle, the new fields such as research and development Vehicular rechargeable, household power supply are transboundary extended to.It is the product of this kind of company, technology, interior
Hold outstanding, in addition brand and marketing ability are powerful, can cut from non-mainstream market, meet specific group and like.
These by global major company or as be referred to as Internet of Things management mode model shared bicycle, share it is electronic
Locomotive or shared electric vehicle etc. are all to control specific products (such as aeroengine, insurance business, bicycle and various electric vehicles
) and particular market resource, along with these companies are thick and solid, advantage technology product builds lower business model be unfolded.Can it
Applied to no specific products, comprehensively setting spread to street Guo, farmland, pipe network, road, underground, more than road surface etc. places Internet of Things
In addition to the equipment such as sensor, gateway, base station, these city Internet of Things even traditional " market " are not net.
Therefore, above-mentioned Successful commercial mode obviously can not directly move over to use.The present invention is quasi- to propose a solution, with benefit
In the promotion of smart city construction.
But it is had the following problems when selecting city Internet of Things business model and chance:
(1) urban operating mechanism or corporate facility manager are not omnipotent
The government functionary of the departments such as alert political affairs, traffic, education, water conservancy or company management are not nearly all Internet of Things professions；
It is required that each public unit (or company) is about to the establishment Internet of Things of department (company) the administered facility certainly, is voluntarily managed, go forward side by side
Row edge calculations, it is unrealistic also infeasible.This provides one good chance of Internet of Things dealer, and it is public to can use its speciality side
Unit (company) builds and runs facility Internet of Things altogether, provides policymaker in particular for edge calculations, each by gained is calculated
Kind of valuable information is supplied to public unit (company), collects service charge, be one can two-win chance.
(2) institutional obstacle
All administration be all divided into each department (such as municipal administration in police's political affairs, traffic, education, water conservancy, agricultural, pipe network,
Fire-fighting etc.), the phenomenon that each administrative department does things in his own way, is very universal, so that the scattered distribution of bulk information, except a small number of for example alert political affairs
Outer with safety supervision, fire-fighting and traffic etc., department rarely has information intercommunication person each other, and it is in fact suitable to want to break hedge Internet of Things of building together
It is not easy, this is for wanting to expand the artificial at very big puzzlement of this field management mode.Operator can be one by one with individual management department
It comes into contacts with, assists the city Internet of Things edge calculations site for establishing the single department, be a chance instead.
(3) network interworking and information sharing
This problem is not only present between the public networks such as telecommunications network, internet, television network, exists in public network and row
Between industry private network and trade Special Network and trade Special Network, between narrowband and broadband etc..This is managed similarly for this field is expanded
There is suitable obstruction when mode, but also provides operator one and expand the chance solved.
(4) deep development of information resources
Currently, many small ranges establish the city of city Internet of Things, between certain some field (such as road traffic,
Disaster preparedness etc.) although having been realized in, inside is small-scale to interconnect, essentially stay at technology and network linking layer
Face, it is insufficient to data mining collected, analysis processing links are restricted, Internet of Things is largely affected
Intelligent Process.Therefore, it is come into contacts with one by one with individual management department by operator for present invention proposition one, it is single that assistance establishes this
The city Internet of Things edge calculations site of department has waited multiple administrative departments that other Internet of Things edge calculations site has been established,
It can be by resources integration；The edge calculations site of individual Internet of Things, citywide data are all built up Deng overwhelming majority department
Information excavating interconnects with regard to when the water comes, a channel is formed.
