Based on above-mentioned hardware configuration, Internet of Things broadcasting method embodiment of the present invention is proposed.
A large amount of appearance of Internet of Things application are greatly enriched the means that people obtain information, have pushed a series of applications Such as environmental monitoring, traffic administration, logistics management, the informationization of smart grid and intelligence.These new applications service both needed Handle the real time information largely obtained from external sensor, and the close phase for needing to consider to apply itself and time and space information Guan Xing, to realize the coordination of complicated aware services.Such as the different terminals in sensor network need to perceive a series of space-times and close The environment attribute of connection, such as the illumination of surrounding, temperature, humidity, object it is mobile, needs are paid close attention in order to application service " scene " or " event " is made and timely being responded.This makes the service (Location-based based on location information Services, LBS) become one of application of internet of things field most prospect, most of public services and quotient based on Internet of Things Industry application all relies on the location information of terminal, and many perception datas are only in the accurate location information Shi Caiyou that terminal has been determined Meaning.Accurate terminal positioning occupies increasingly consequence in Internet of Things location-based service application.
The fast development of Internet of Things location-based service application, although providing convenience for user, also exposure has Internet of Things Some problems of network technology:
1, technology of Internet of things itself lacks precise positioning ability；
2, transmission differential data can occupy a large amount of downlink bandwidths, it is difficult to meet requirement of real-time；
3, lack region blur query capability, it is difficult to identify numerous terminals in specific region；
4, terminal positional information is related to serious privacy threats, restricts Internet of Things development；
5, multiple terminals batch interactive operation real-time is low, and specific occasion application is limited.
The present invention solves problem above, especially narrowband wide area digital broadcast technology using digital broadcasting, such as CDRadio, CDR, DRM also have some key features of LPWAN technology: low-power consumption, wide area covering, high density connection.Especially In terms of being Connection Density, broadcast technology system theoretically can support unlimited terminal to connect, especially meet Internet of Things MMTC (Massive machine-type-communications, flood tide machine type communication) developing direction.
Using digital broadcast technologies (such as CDRadio) to Internet of Things bottom-layer network terminal broadcast differential data, Ke Yibang Terminal is helped to realize differential position, so that new Internet of Things framework has precise positioning ability.It also advises well simultaneously The temporal correlation and spatial coherence problem of differential data transmission are kept away.Firstly, the propagation delay time of digital broadcasting be it is fixed, It is not influenced by terminal connection quantity, the real-time of differential data transmission is no longer a problem.Secondly, digital broadcast base stations Position is fixed, and signal coverage areas is Given information, and differential data and the matching problem of terminal in specific region are readily solved, Because the problem of " having what object in specified region ", having had changed into " specified object (differential data effective district) is in what position Set (broadcast base station signal coverage) " the problem of.
For terminal, as long as digital broadcast signal can be received, just belonging to naturally " has what in specified region One of answer of object ", this just provides region (broadcast base station signal coverage) fuzzy query ability for location-based service.At this Under a mechanism, terminal can keep silent, upload own location information without consuming upstream communications bandwidth and power consumption, also avoid The problem of location privacy exposure.For needing the case where outwardly providing location-based service using terminal positional information, the present invention It also proposed two kinds of processing methods (see summary of the invention), the risk of location privacy exposure can be evaded.
It fixes because broadcast technology naturally has signal propagation delay time, connect unlimited feature.By digital broadcast path, By homogeneity control data distributing (such as the traffic light control in some city) towards multiple terminals, can well solve numerous The real-time and stationary problem of terminal operation are particularly suitable for needing the Internet of Things application type of batch real-time control.
The present invention provides a kind of Internet of Things broadcasting method, which is mainly used on broadcasting station, in object In one embodiment of broadcasting method of networking, referring to Fig. 2, the Internet of Things broadcasting method includes:
Step S10, terminal of the broadcasting station in the form of digital broadcasting into predeterminable area send service channel signal；
Step S20, broadcasting station obtain the service subscription request that terminal is fed back based on the service channel signal, and according to institute It states service subscription request and determines target subscription service；
The target subscription service is sent to network server by step S30, broadcasting station；
Step S40, if broadcasting station receives the target that the network server is fed back based on the target subscription service Service content, then the terminal in the form of digital broadcasting into the predeterminable area sends the destination service content.
Particular content is as follows:
Step S10, terminal of the broadcasting station in the form of digital broadcasting into predeterminable area send service channel signal；
Digital broadcasting is added to the bottom-layer network of Internet of things system by new Internet of Things framework, obtain a low delay, The relevant down going channel in spatial position.For the distribution convenient for data content, can be ordered using publication in web server software level The design pattern read forms one and is based on space bit confidence by the creation of each broadcasting station at the distribution subscription channel of a downlink The distributed post subscription covering network constructed is ceased, is provided for Internet of Things service a kind of based on regional location (broadcasting station signals The area of coverage) running environment.The framework of the distribution subscription system is as shown below.
Terminal only needs to submit the demand of oneself, is embodied as subscribing to, and can receive service system active push later Service content, without constantly repeat submit inquiry.
The pressure of network service can be significantly reduced in this mode, promotes user experience.Such as during the course of the Olympic Games, great Liang Xiang Same inquiry (various countries' gold medal situation etc) load is concentrated within a very short time, and server overload is caused even to collapse.Therefore, it adopts With the asynchronous event driven mode based on distribution subscription, system service capacity can be significantly improved.As a kind of effective data Distribution method, distribution subscription can realize the loose coupling interactive mode of multi-to-multi between data producer and consumer naturally, Meet network service dynamic, asynchronous feature, is vital for creating data-centered network service.With shifting The popularization and application of dynamic internet and Internet of Things, the distribution of data become more and more important with shared, and distribution subscription is increasingly becoming communication pattern Normality.)
The broadcasting station terminal in the predeterminable area in the form of digital broadcasting into the broadcasting station coverage area in the present invention Send service channel signal.The service channel signal includes tunnel name, and the tunnel name is ordered as each terminal service Read the concealment title of request.
Step S20, broadcasting station obtain the service subscription request that terminal is fed back based on the service channel signal, and according to institute It states service subscription request and determines target subscription service；
Internet-of-things terminal receives operational feedback corresponding service subscription request of the meeting based on user after digital broadcast signal, Such as weather forecast, traffic behavior etc. necessarily correspond to the distribution subscription channel for having gone up broadcasting station as long as it can receive signal.
Specifically, the broadcasting station obtains the service subscription request that terminal is fed back based on the service channel signal, and root The step of determining target subscription service according to the service subscription request include:
Step A1, broadcasting station obtain all service subscriptions that each terminal is fed back based on different service channel signals respectively and ask It asks, and determines the service subscription table of counterpart terminal according to each service subscription request；
Step A2 determines the channel subscription table in the broadcasting station according to the service subscription table, and is ordered according to the channel Read the target subscription service that table determines the broadcasting station.
It is understood that the service channel signal gone out transmitted by broadcasting station can have it is multiple, for different terminals into Row selection.Terminal issues service subscription request by data feedback channels such as NB-IoT, subscribes to and channel BiSpatial position it is relevant Service content；And broadcasting station generates service subscription table CT (i.e. clothes ordered by different terminals according to the subscription information of all terminals Business is formed by terminal-service subscription table CT), calculate the subscription table BT in distribution subscription channel.
Referring to Fig. 3, the C GC group connector of service subscription table CT is identified, and T represents service, and numerical value 1 indicates the corresponding terminal of the column Service corresponding to the row is had subscribed, 0 indicates not subscribe to.Subscription table CT in upper figure expresses T1~TmM service by n Terminal C1~CnSubscription situation.T is serviced for somejAs long as there is a terminal to have subscribed the service, corresponding channel Bi Just need to subscribe to the service, the i-th column jth row of channel subscription table BT needs to be set as 1.(the broadcasting station columns k of channel subscription table BT Quantity) it is much smaller than the columns n (internet-of-things terminal quantity) of subscription table CT, this is the key that realize MMTC high concurrent amount.By channel Subscription table is it is found that all target subscription services subscribed to required for current broadcast station.
Further, the broadcasting station obtains the service subscription request that terminal is fed back based on the service channel signal, and The step of determining target subscription service according to the service subscription request further include:
Step B1, broadcasting station obtain the service subscription request that feeds back based on the service channel signal of terminal, described in detection Service subscription request is requested with the presence or absence of far call；
Step B2, if so, obtain the far call parameter in service subscription request, and by the far call parameter and The service subscription request is sent to the network server, and obtains the network server and be based on the far call The remote service content that parameter and the service subscription request are fed back in the form of digital broadcasting；
Step B3, if it is not, then executing the step of determining target subscription service according to the service subscription request.
To avoid terminal privacy position from revealing, the present invention proposes a kind of location-based service mechanism of far call, position is taken The calculating task of business is transferred on the internet-of-things terminal of terminal from the application system in cloud and carries out.Terminal is completed only will after calculating The result of location-based service returns to (such as charge information), without the precise position information of exposure itself.
And broadcasting station is only used as the information intermediary of terminal and network server, so as to avoid terminal privacy location information Leakage.
Internet-of-things terminal realizes RPC (Remote Procedure Call, a remote procedure call) service, 1, broadcast It stands and obtains service subscription request, and the request is detected, to determine whether there is far call request.If so, then obtaining The far call parameter, and far call parameter and service subscription request are sent directly to network server；2, network takes Business Program extraction, which goes out in service, needs terminal precise position information to participate in the process calculated, by the execution program of this calculating process With other necessary input parameters, all parameter as RPC function；3, it is determined eventually by the position of terminal anonymous (i.e. channel ID) Corresponding distribution subscription channel is held, and network server, using RPC parameter as service content, is pushed to this as publisher Distribution subscription channel；4, these service content (i.e. RPC parameter) are broadcast based on distribution subscription channel and are covered to signal by broadcasting station Target terminal in area；5, after terminal receives RPC parameter, the execution program and input parameter of calculating process have just been obtained, then will Itself precise position data is also used as parameter input to execute program, runs calculating process；6, after calculating, terminal will be calculated and be tied Fruit returns to location-based service application system by the data feedback channel of NB-IoT etc, just completes this RPC task；7, network takes Business program receives RPC as a result, continuing to execute other calculating process of location-based service, returns to final result to user.
Specifically, it is illustrated using subscription weather forecast.Terminal subscribes to weather forecast service, and broadcasting station determines that celestial body is pre- Service content is reported, but due to the presence of RPC far call parameter, does not obtain specific terminal location, but by RPC far call Parameter and service subscription request are sent to network server jointly, after work network server configures corresponding weather forecast content Broadcasting station is returned to, to be directly obtained weather forecast information.During this, broadcasting station only carries out letter as information intermediary Cease the instrumentality of transmitting.
The target subscription service is sent to network server by step S30, broadcasting station；
Step S40, if broadcasting station receives the target that the network server is fed back based on the target subscription service Service content, then the terminal in the form of digital broadcasting into the predeterminable area sends the destination service content.
Routing when network server generates corresponding data content according to the target subscription service in broadcasting station, in broadcasting station Engine pushes data content according to the subscription situation of destination service content and channel subscription table BT in target subscription service To the channel (broadcasting station) for having subscribed to the service；
After broadcasting station receives data content, it is modulated into wireless digital broadcasting signal, is broadcast to the object in signal coverage areas Networked terminals (subscriber).
Specifically, if the broadcasting station receives the mesh that the network server is fed back based on the target subscription service The step of mark service content, the then terminal in the form of digital broadcasting into the predeterminable area sends the destination service content, wraps It includes:
Step C1, broadcasting station receive in the destination service that the network server is fed back based on the target subscription service Hold, and obtains the local position parameter in the broadcasting station；
Step C2, local destination service of the broadcasting station in the destination service content according to the local position Parameter analysis of electrochemical Content；
Step C3, terminal of the broadcasting station in the form of digital broadcasting into the predeterminable area send the local destination service Content.
In the present embodiment, the built-in routing engine in broadcasting station can carry out position screening to destination service content.Many targets Service content naturally has position attribution, such as weather forecast, real-time road, differential data, Street lamps control etc..With weather forecast For, the terminal for having subscribed this service content usually only needs to receive the Weather information in itself location, rather than all. Broadcasting station routing engine will be when data content be issued in weather forecast service, according to the local position parameter in broadcasting station (such as institute In city) it is assigned to specific distribution subscription channel (broadcasting station), the terminal in the broadcasting station signals area of coverage is obtained Obtain local Weather information.Similarly, the effective district (such as in 50 kilometer radius of base station periphery) of differential data, Street lamps control Target area (such as some city) this kind of space position parameter all can serve as the calculating parameter of routing engine.
Therefore, the routing engine in the present invention is using location-based routing mechanism, according to local position parameter come Destination service content is divided, it can be by all subscribers of these destination service content-datas into signal coverage from broadcasting station (internet-of-things terminal) push.
