Description
Technical field
The present invention relates to the technical fields more particularly to one such as image recognition, Distributed Calculation, p2p networks and image procossing
The method and system of promotion driver whole-visible area of the kind based on block chain and intelligent contract.
Background technology
One of an important factor for whole-visible area of driver is traffic safety.The reason of many traffic accidents occur all be because
Range of visibility for driver is narrow excessively close or sight is blocked by barrier, makes driver that can not be made to the traffic of burst
Reflection.
Number of patent application 2017113704035 (a kind of method and device promoting traffic whole-visible area) provides a kind of incite somebody to action
The video pictures of near roads other electronic equipments shooting synthesize on vehicle-mounted main video pictures, are that driver passes through mobile unit
Main video pictures, comprehensively understand surrounding road condition.But such display methods needs mobile unit to carry out at a large amount of image
Reason, next needs to consume a large amount of network bandwidth resources, again, such display methods do not provide solve machine and machine it
Between effective method of commerce.
Invention content
In order to solve problem above, the present invention provides a kind of promotion driver's intervisibility based on block chain and intelligent contract
The method and system of range.
A method of promotion driver's whole-visible area based on block chain and intelligent contract, including：
1 subscription client sends service request to background server；
Subscription client is dynamically assigning in different sub-network groupings by 2 background servers；
3 subscription clients issue the video flowing demand of particular geographic location using intelligent contract in the grouping from network
And bonusing method, the intelligence contract operate in block chain network；
After sensor node in the 4 sub-network groupings receives the task of the intelligent contract publication, by video flowing
Data are sent to the subscription client；
After 5 subscription clients receive video stream data, hair message is to the intelligent contract, the intelligence contract prize
Encourage the sensor node that video flowing is provided.
Further, the background server is provided according to subscription client User ID, operator's informaiton, user client
Subscription client is dynamically assigned to suitable son by the information such as the loading condition of end actual geographic position and the grouping of each sub-network
In network packet.
Further, the video flowing demand of the intelligent contract publication is the video of the particular geographic location after subscribing to N seconds
Stream, after the sensor node in sub-network grouping is connected to video flowing demand task, according to the intelligent contract needs, N seconds
Video flowing is sent afterwards to subscription client, after the subscription client receives video stream data, sends messages to the intelligence
Contract, the intelligence contract reward provide the sensor node of video flowing.
Further, according to the client's number for subscribing to video flowing after N seconds, estimate oneself network bandwidth is the sensor node
It is no enough, if network bandwidth is insufficient after the sensor node calculates N seconds, it is grouped in the sub-network using intelligence and about two
Middle publication video stream bandwidth demand, the intelligence and about two operate in block chain network two, bandwidth in the sub-network grouping
After sufficient sensor node is connected to the video stream bandwidth demand, the video flowing of the insufficient sensor node transmission of reception bandwidth
Data, and provide video stream data download service to the user, after user receives video stream data, the insufficient sensor section of bandwidth
Point sends messages to the intelligence and about two, and the intelligence and about two rewards provide the sensor node of bandwidth service.
Further, the video flowing demand of the intelligent contract publication is that M suitably sensor nodes is needed to provide tool
The task of the video flowing in body geographical location is sent after M suitable sensor nodes in the sub-network grouping are connected to task
Video stream data is to subscription client, and after subscription client receives video stream data, hair message is described to the intelligent contract
Intelligent contract reward sends the sensor node of video flowing.
Further, the intelligent contract publication needs to provide particular geographic location surrounding vehicles position data and week
The task of the data information of pedestrian position is enclosed, after the sensor node in the sub-network grouping is connected to task, according to the biography
Sensor node acquisition the particular geographic location nearby video stream data, calculate the particular geographic location nearby vehicle and
Pedestrian's data are sent to subscription client, after subscription client receives the neighbouring vehicle of particular geographic location and pedestrian's data, root
According to unified vehicles or pedestrians model rendering on vehicle-mounted main video pictures, while the subscription client communication intelligent contract,
The intelligence contract reward provides the sensor node of data.
Further, check that server sends the bat for including random time place using intelligent contract three-dimensional subscription client
According to or video task, the intelligence and about three operates in block chain network three, in the subscription client for wanting seeking time and position
After receiving the task, by photo or video stream to server is checked, the inspection server is according to subscription client
The photo or video flowing of offer judge the video flowing or road condition data authenticity that task location sensor node provides, if the biography
The data that sensor node provides are untrue, and the inspection server rejects the sensor node from sub-network grouping, and
Supplement new sensor node；Intelligence and about three described in the inspection server communication simultaneously, the intelligence and about three rewards provide
The subscription client of photo or video flowing.
Further, server receiving sensor node video flowing or sectional drawing are checked, according in the same time or different moments institute
Sectional drawing or video flowing that the safety sensor node near sensor node position provides are stated, the sensor node data is calculated
Authenticity, if the data that the sensor node provides are untrue, the inspection server is by the sensor node from subnet
It is rejected in network grouping, and supplements new sensor node.
A kind of system of promotion driver's whole-visible area based on block chain and intelligent contract, including：
Subscription client, for submitting service request to background server, the video provided for receiving sensor node
Stream or road condition data；
Background server, for according to subscription client actual conditions, subscription client to be dynamically assigning to different sons
In network packet；
Sub-network is grouped, for building the networks P2P between subscription client and sensor node；
Sensor node calculates vehicle and pedestrian traffic data for acquiring scene video stream, and according to video flowing；
Intelligent contract, for realizing the process of exchange between machine and machine；
Block chain, for confirming transaction；
Check server, video flowing or road condition data for providing sensor node check.
A kind of method and system of promotion driver's whole-visible area based on block chain and intelligent contract provided by the invention,
The transaction between machine and machine is realized by intelligent contract and block chain, and sensor video flowing is sent to by the networks P2P
Subscription client reduces network delay, provides comprehensive road view for driver in real time, reduces traffic safety hidden danger,
Sensor node data authenticity is checked by random subscription client simultaneously, reduces sensor node network security risk.
