Description
Technical field
The present invention relates to message area, more particularly to a kind of networking synchronization of active node and management method.
Background technology
It is increasingly urgent in the indoor environment that satellite navigation system is difficult to cover, the demand of location-based service.People more than 80%
Time is in indoor environment, with the continuous development of social modernization's construction, increasing, the indoor location service of heavy construction
Demand be just continuously increased.The neck such as security monitoring, business and personal-location services, the management of large stadium pipe, special population monitoring
Domain is required for using accurate indoor positioning information, particularly when tackling the emergency scenes such as emergency evacuation, indoor positioning information
Even more it is particularly important.Increasingly urgent with the demand of indoor location service, location-based service is just starting from outdoor navigation to room
Inside and outside seamless navigation is changed.
China cellphone subscriber is up to 1,000,000,000, and for the number of users related to location-based service more than 500,000,000, development is swift and violent.Capture
The indoor positioning market of cellphone subscriber turns into the hot spot for competition in location-based service.
IBeacon is the localizer beacon node that Apple Inc. releases, and mobile phone is measurable to arrive iBeacon（Bluetooth）Node connects
Intensity is received, so that it is determined that the position of oneself.Mobile Telephone Gps, favor information push, member's integration can be carried out using iBeacon nodes
A series of services such as acquisition.
For iBeacon systems, how to manage iBeacon nodes and ensure that the security of iBeacon nodes turns into
An important ring for its application.IBeacon realizes the identification of identity by broadcasting the ID number of oneself, and mobile phone is by receiving not
Signal intensity with node is positioned.The ID number of iBeacon broadcast is by " UUID "+" marjor "+" minor " three parts group
Into.Because iBeacon agreement is disclosed, Android mobile phone can scan the complete id information of all nodes at scene, therefore
At least following three aspect safety applications be present, limit the popularization of its application：
（1）Businessman A disposes iBeacon nodes, carries out location navigation, then B can not needed with the ID number of scan node
Location navigation service is equally carried out using the node of A deployment in the case of hardware input, at this moment iBeacon actual deployment sides A institutes
It is unwilling what is seen；
（2）Businessman A disposes iBeacon nodes, push based on favor information, rival B can be with scan node
ID number, so as to it is counterfeit go out a collection of same ID node disposed in market A, cause businessman A alignment system to be fully sunk in confusion；
（3）Businessman A disposes iBeacon nodes, carries out the activities such as location-based favor information push, member's integration（Such as
To shop have it is preferential, to shop increase integration etc.）.B can with the ID number of scan node, so as to it is counterfeit go out a collection of same ID node go out
Sell, for brushing the malicious acts such as integration.
In addition, iBeacon nodes can only carry out signal broadcast, how can not be managed by the information back of itself to backstage
Node, it is found that whether node is lost or do not signaled, and turns into a great problem in system operation.
For solve the problems, such as node by it is counterfeit, usurp, there is invention to propose node dynamic encryption technology, the ID of node at present
It is demodulated with the time according to certain rule dynamic change, mobile phone according to current time.But this method needs node and mobile phone
When it is synchronous.Due to node time can gradual sideslip, therefore need at regular intervals to node carry out a time adjustment,
The process is more troublesome.
In terms of node administration, current fresh approach is installation Bluetooth gateway, and Bluetooth gateway detects periphery Bluetooth beacon
（iBeacon）Node, detection case is reported into management server.But because the signal transmission power of bluetooth positioning node is low,
Therefore bluetooth webmaster detection range is limited, just can not receive signal every a face wall substantially in market, therefore to realize that market is determined
The complete monitoring of position system is, it is necessary to which substantial amounts of Bluetooth gateway, hardware cost and construction cost are all very high.
The content of the invention
The present invention solves the technical problem of the networking synchronization for providing a kind of active node and management method, pass through elder generation
Calibrate all mid-side nodes, again by all mid-side nodes to the periphery node prover time with realize the whole network time synchronized calibrate, and again with section
Point is transmitted instead of the needs that conventional bluetooth equipment covers without dead angle, cost-effective, convenient and swift, economical and practical, active
There are extensive market prospects in the synchronous popularization with management method of the networking of node.
