Description

The heterologous Internet of Things edge calculations system and method in city being arranged according to management category

Technical field

The invention belongs to internet of things field, are related to a kind of heterologous Internet of Things network edge meter in city being arranged according to management category Calculate system and method.

Background technique

City, garden, scenic spot, building site, cell, building, means of transportation, river, lake, etc. intelligent management pair The information process- of each related infrastructure proposes very high request.It needs to make full use of technology of Internet of things, to all kinds of relevant rudimentaries Mass data produced by the sensing equipment of facility, is acquired, handles, storing, analyzing, transmitting and the intelligent processes such as solve. To realize " feel, pass, knowing, with " integrated smart city Internet of Things application, certain facility problem, i.e. can be known immediately When confirmation problem point and degree occurs, solve early.The everything of avoiding over all detects with manpower, checked, it is this superfluous to solve Long and inefficient disadvantage.Technology of Internet of things greatly mentions to realize that area equipment facilities information, intensive management provide condition High city management efficiency.

The public and private wisdom region and city for building intelligent, intensive, low-carbon, green, safety, need to realize the public base in the region Comprehensive access Internet of Things of Infrastructure, professional service facility.Sensing equipment and access device in wisdom region and city it is more Sample is main feature of the Internet of Things relative to internet in current and later development.How Internet of Things are efficiently and conveniently connected How sensing layer equipment in net more effectively merges different types of sensing data, and calculates more accurate value information, makes The data of bottom acquisition can to meet to greatest extent service application demand particularly important.

As the large-scale promotion in wisdom region and city is built, in the information system management of urban infrastructure, it would be highly desirable to solve Certainly several difficult points that thing network sensing layer field encounters:

1, push the institutional obstacle of city Internet of Things: the administration in All Countries city all classifies, such as alert The phenomenon that political affairs, traffic, education, water conservancy, agricultural, pipe network, fire-fighting etc., each administrative department does things in his own way, is very universal, so that information Though it is scattered to measure huge but distribution, in addition to minority is such as alert political affairs and safety supervision, fire-fighting and traffic, department rarely has information mutual each other Logical person wants to break hedge Internet of Things of building together and is quite not easy in fact.This is that the present invention wants first to push away one by one according to administrative department's classification The edge calculations system of individual departments is moved to reduce resistance, has waited the city Internet of Things edge calculations system of most of administrative department It is completed through construction, then by mutual connection, just when the water comes, a channel is formed.

2, sensing equipment has volume and diverse problems: urban public infrastructure, such as road, pipe network, water power, city It builds etc., the facility in each private field and monitored river and lake hillside and meteorology, the environmental sanitation of regional area etc., is related to multiple types Sensor equipment, internet of things equipment and communication, 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, being and not being, not Detect his time variable；Its substantial amounts but smaller with edge calculations relationship.Second class is to detect broad sense physical quantity at any time The sensor of variation, such as temperature sensor, strain gauge, strain transducer, magnitude of traffic flow sensor, water flow sensing Device, flow sensor, water level sensor, water pollution sensor, PM2.5 sensor, monitoring camera device etc., though quantity is not so good as The first kind it is more, but 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 or tunnel etc.) sensor special (such as strain transducer, shock sensor, temperature sensor) built of institute's cloth, position Set fixation, length or area also specialization.Another kind is dispersed in the sensor of each not privileged site in city, such as traffic Monitor sensor, level of ground water sensor, the sensor along the setting of rain (dirt) water drainage pipeline, soil moisture content sensor, water body Contaminant 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 government regulator), there are still data for this The problems such as transmission traffic congestion, fault, information are cracked.If can generate point in data by edge calculations is subject to calculation processing, directly It is controlled by government regulation unit, 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, it is unable to intercommunication each other.Most of existing solutions be heterologous sensor respectively with The gateway of oneself uploads to cloud and does integrated treatment, generates judgement and decision.Even so, for omnifarious Urban operating mechanism gives municipality after being provided with examination by every profession and trade specialized company, subsequent action, maintenance, data adopt a word used in person's names, Information processing etc. is quite numerous and disorderly, leads to the problem of very much.

The present invention aiming at the problem that the second class sensor proposes that the administrative department (can be government according to management category Or private corporation) be distinguished into section along the facility administered or river and lake hillside etc., every segment length be d (narrowband communication it is effective away from From), it is necessary to carry out every section of center of edge calculations edge calculations and transfer point (referred to as calculating point) are arranged, in its week Side it is existing or it is following increased heterologous sensor is packed up, acquisition data on the spot, calculate, filtering, encryption, storage；It selects again Information fusion is further done at crossing followed by edge calculations station in selecting property ground, obtains the systemic complete information of the facility or landscape, And after different information fusions generations items new information；Background server is uploaded to again or descends into lower end operation actuator. Point is calculated also with wrong function is detectd, can detect the sensor of exception or failure nearby, is maintained easily and is managed be packaged sensor, Also it builds and uses conducive to the cloth of big quantity sensor.

3, the transmission of magnanimity sensing data and processing problem

In current environment of internet of things, the main problem that sensing the data obtained faces is: access point is numerous, connection management is multiple Miscellaneous, data volume is big, data sharing demand is strong etc..Although omnipotent solution is regarded as in cloud by everybody, actually this is not so. Wherein there are three major issues:

1) cloud computing no doubt provides magnanimity calculating and storage capacity, but its capacity is not infinity, and computing capability is more non- It is infinite strong.Smart city and the more and more more digitisations of intelligence community construction, the single one sensor of data perception layer, such as The camera data per second that may produce up to GB~TB meter, cloud computing and storage load are increasing；Simultaneously because network bandwidth Limited, the problems such as high transmission cost and higher response are delayed, consequence causes that network delay is increasingly severe, cost is acute It rises.Sea caused by network edge device cannot be effectively treated based on the centralized data processing method of cloud computing model in tradition Measure data；Need the solution of innovation.

2) for cloud computing problems faced, the Si Teer Buddhism of Columbia University: New York, United States is awarded (Prof.Stolfo) in 2011 propose " mist calculating " concept, Cisco System Co., the U.S. (Cisco) in 2012 by expansion push away Extensively；The cloud in the remotest places is drawn the puzzlement for attempting to solve cloud computing to mist is become at one's side.However mist calculate concept be still it is fuzzy, Computing capability and data analysis application can be extended to network " edge " by it, it enables client in local analytics and management number According to obtain real time information.But it is still unclear how to execute mist calculating.

3) having quite big ratio in the initial data that sensing layer obtains is repetition or useless data.Such as it is important at 10 Video surveillance is established in intersection, and main purpose is to do traffic data acquisition, record of traffic violations event etc., without that will take All videos obtained all upload to cloud platform, not only occupied information transmitting bandwidth, but also cause waste of storage space.

The final solution of three above problem is attributed to a bit, is exactly to be produced in data using edge calculations thought Raw first pre-processes on the spot, and necessary data is screened, or even is suitably calculated, then result is sent to cloud processing. Such as computing function is assigned in aforementioned intersection, the valid data such as vehicle flowrate, vehicle, speed are captured with pattern recognition software, And violation event is filtered out, which is uploaded to cloud in a manner of several photos (wherein comprising people, vehicle, licence plate, time etc.) Traffic monitoring server can filter 90% or more " rubbish grade " film shelves that need not be uploaded.

But how efficiently to accomplish edge calculations or mist calculates or a big problem.From existing various documents or Patent is learnt, in terms of the automatic implement of altitude figure and industry internet, for edge calculations put forth effort it is very deep, Gradually implement edge calculations " edge calculations framework 2.0,2017/11, industry internet industry alliance, side in the respectively industrial site Edge calculates industry alliance ".In the edge calculations framework propose an abstract edge calculations node (ECN), be intellectual capital, Intelligence system, intelligent gateway etc. have digitlization, networking, intelligent common feature, it is possible to provide the ICT such as network, calculating, storage Resource, with logically unified concept.According to the typical case scene of ECN node, system defines four class ECN exploitation frame Frame.Every class Development Framework provides operating system, functional module, the Integrated Development Environment etc. of matching scene.Based on this frame Derive six class products: embedded controller, free-standing controller, perception terminal, intelligent gateway, edge distribution formula gateway, side Edge distributed server.It is flourishing that these frameworks have significantly expedited the emergence of the Internet of things control device based on electric appliances various in one family Exhibition.Elevator management, the public electricity utilization management etc. for further expanding to upper one hundred houses residential building are applied and what is serviced opens Hair.These edge calculations nodes have a denominator in fact, be exactly have specific edge (industrial workshop, workshop, it is a Other front yard or a specific building).Even packaged type edge calculations that are vehicle-mounted or being worn on device with individual, also have bright True device medium.

However urban operating mechanism monitoring, the city field Nei Gesi for example residential quarters, garden, in terms of, how to implement The network architecture of smart city Internet of Things, how to being dispersed in the heterologous of city magnanimity (in terms of up to a million, more than one hundred million) everywhere Sensor makees edge calculations and mist calculates, and remains at an incubation period at present, there is no mature available solution so far.

The present invention proposes the management category according to public field (municipal administration), such as traffic, underground pipe network, environmental sanitation, meteorology, street lamp Deng, or residential quarters, tourism garden, the industrial park in private field etc., according to its handling facility route, such as one monitored River, means of transportation, the every safety devices of private road in scenic area of roadside etc., exist along its route Edge calculations point is arranged in the effective distance (d) of Internet of Things narrowband communication, is packaged and manages its periphery with numerous different on a route Source sensor, data decoding and primary Calculation, upload to the computer installation in big grid after selecting effective information, carry out two again Secondary processing；Finally just it is transmitted to cloud server.The edge calculations that mist is calculated as some specific centers can so be changed；It can help The propulsion of smart city mist networking.

4, how Internet of Things accomplishes that information security is a serious problems in the case where all things on earth can join
