Description
Technical field
The present invention relates to the building method of field of communication technology more particularly to the white frequency spectrum resource service network of Internet of Things and it is
System.
Background technique
In Internet era, network has penetrated into the various aspects of life.But for the resident of remote countryside,
It cannot connect to network because of remoteness.Country energetically advocate Internet of Things and internet+in the case of, mentioned for remote countryside
For stabilization, easily promote, easily the broadband network built be develop Internet of Things and internet+basis.Therefore it provides low cost,
The easily stable rural area Solution of Wireless LAN of deployment, performance becomes very important research field, and receives government
Pay much attention to.
Building for network is broadly divided into two classes: cable network connection and wireless network connection.Wherein, cable network connects
It is to be connected on router or interchanger to be connected to the network by cables such as optical fiber, cables.Wireless network connection can be divided into
The network connection (such as mobile, connection) of mobile communications network connects that (such as WiFi is commonly used and taken 802.11 with Wireless LAN
The WLAN etc. of agreement).But these are unsuitable for carrying out broadband access in remote countryside.Main cause is as follows:
(1) since the area in rural area is bigger, population is more dispersed, and the position in some rural areas is very remote, if
Network connection is provided to resident by being laid with optical fiber and cable, then needs complicated and huge network system.But network
Utilization rate it is low cause costly, can thus make the equipment investment of early period larger and make charge higher, thus generalization
Difference.
(2) be not suitable for carrying out broadband access using mobile communications network.Although can achieve now by 4G network
The downstream rate of 100Mbps can achieve the demand of network, but the mobile network signals of remote countryside cover difference and mobile network
The expense of network is too high, thus is also unsuitable for promoting Rural Broadband access.
(3) since WiFi is using the common frequency band of 2.4GHz, the transmission range for providing satisfied performance only has
50-100 meters, it is not suitable for long distance transmission.Although long-range network can be built by multirouting, increase additional set
It is standby to inevitably result in the equipment cost increase for building network and be equally unfavorable for promoting, be not suitable for building for rural area network.
By the shortcomings that analysis above scheme it is found that for rural area linking Internet needs provide a kind of easily deployment and it is low at
This communication network.

The embodiment of the present invention is illustrated, to server-side send registration information before, by socket socket with
Server-side establishes communication connection.
In the present embodiment, agreement uses TCP reliable transport protocol.After establishing completion socket network communication, lead to
Send () function and recv () function are crossed to carry out sending and receiving for data.Specifically, it is sent out by socket to server-side
Send communication connection request REQUEST_AVAILABLE_DB.The data structure of the communication connection request is as shown in table 2:
The data structure of 2 communication connection request REQUEST_AVAILABLE_DB of table
After sending communication connection request REQUEST_AVAILABLE_DB, server-side can return to confirmation message CONFIRM_
AVAILABLE_DB, to show successful connection.
Step S120: white spectrum information response is received；
Step S130: frequency hopping is carried out according to the white spectrum information received, so as to be communicated in white frequency spectrum bands.
Step S140: white spectrum information is broadcasted, so that other equipment be enable to perceive white spectrum information, and energy
Enough frequency hoppings are communicated to white frequency spectrum bands.
What needs to be explained here is that in the Web Calling Google Maps API of server-side, so as to
The geographical location information of communication equipment is shown on Google Maps.Specifically, Web browser sends map datum request,
Google Maps server receives request inquiry map data base, returns to the data of XML format, Web page parses XML data will
Map denotation comes out.Since equipment is stored with longitude and latitude information in white spectrum information database, server-side is connecing
When receiving the required parameter with latitude and longitude coordinates, device location can be shown on Google Maps.
In the present embodiment, server-side is cloud platform.
There is also the need to explanation, white spectrum information is stored in each pixel on map by the embodiment of the present invention
