Description
Technical field
The present invention relates to wireless communication technology field, more particularly, to a kind of wireless Internet of Things access with tcp/ip network docking
Net Transmission system.
Background technology
Positioned at Xinjiang province Kaxgar Prefecture Shache County and Prefecture of Kezilesukerkezi Aketao intersection Yarkanthe River
The A Er Tasha water-control project of mainstream sector lower reache is that have flood control, irrigation, the controlling key water control project of generating effect
Engineering, has the good reputation of Xinjiang Small Three Gorges.A Er Tasha water-control project belongs to big (i) type engineering such as i.Engineering construction chief engineer
Phase is 74 months, and total investment of engineering is 10,023,880,000 yuan, is country 13 plan emphasis investment project.
A Er Tasha water-control project needs dam roller compaction process is realized with digitized tracking, and monitoring dam filing rolls
Process.Follow the tracks of the field data collecting to upload onto the server, be that dam roller compaction construction process provides complete process data.
Therefore scene must assure that stable wireless network supports the transmission of data.
Scene can use operator (telecommunications, movement, UNICOM) 3g/4g access network, but local remote, swinging of signal
Fixed, cause data often can not be back to server in real time.Investigate following several schemes for this, but all cannot solve very well to ask
Topic:
Oneself sets up 3g/4g base station: cost of access is higher, and needs to apply for frequency range licence plate, implements extremely difficult.
Wifi solution: according to ieee802.11 standard, the ultimate range 100 that general wireless router can cover arrives
In 300 meters, blocked affect larger.Field requirement coverage distance will reach 1 to 2 kilometers, and therefore wifi solution can not expire
The demand of sufficient field operation.
High-power bridge: the high-power bridge using beam antenna can reach certain communication distance, but its coverage
Narrow；And can reach certain coverage using the high-power bridge of omnidirectional antenna, but communication distance is near.And high-power bridge is subject to
Block impact than more serious.Therefore high-power bridge can not meet the demand of field operation.
General radio set communication: directly cannot communicate with tcp/ip network connection, need existing equipment software and hardware is changed
Make.Even if after transformation, it communicates as one-to-one, half-duplex operation (i.e. cannot simultaneously twocouese communication).If necessary to entirely double
Work communicates, and needs to dispose two sets of systems between two points and is respectively used to up, downlink communication.Dispose extremely complex, and become
This is very high.And in the case of for multiple spot, it is more serious to interfere ratio, therefore general station telecommunication can not meet field operation
Demand.

Described data is activation gives described server.Receive server after covering the data that linkup transmit comes, extract in data and take
The set hyphen of band, inquires about above-mentioned matching list according to above-mentioned set hyphen, judges described to cover whether hyphen has stored in
Join in table, if it is, obtaining the wireless transfer channel number of the described set hyphen association of storage in matching list, by this wireless biography
Defeated channel number data is transferred to and is wirelessly transferred control submodule.Otherwise, returning to server does not have receive to be wirelessly transferred list
The notification message of unit.
In actual applications, when network transmission interruption, the data storage of collection can be got up by sensing acquisition equipment,
After network transmission is recovered, then the historical data of storage is reported to server.In this case, if historical data is a lot,
It is possible to the just equipment in normal work in current network can be affected.Gateway needs to have intelligence in docking
Process the ability of this situation.Specific strategy and algorithm are described such as to multiple wireless transmission unit with a wireless transmission gateway
Under.
Therefore, in this wireless-transmission network, defining uplink is from wireless transmission unit to server side to descending
It is transmitted as server to wireless transmission unit, and it is as follows to define systematic parameter:
Wireless transmission bandwidth: up bu, descending bd
The number of the wireless transmission unit of a wireless transmission gateway service: n in network
In network, each equipment uplink transmission data amount is au1,au2…aun
The real-time higher uplink bit rate of each equipment: r in networku1,ru2…run
In network, each equipment downlink transmission data amount is ad1,ad2…adn
The real-time downlink transmission data rate of each equipment: r in networkd1,rd2…rdn
For wireless transmission gateway, within the t time, network uplink occupancy transmission bandwidth is:
For wireless transmission gateway, within the t time, network downstream occupancy transmission bandwidth is:
If butClose to buOr bdtClose to bd, when qos is close to minimum restriction, then can determine that bandwidth have impact on
Normal transmission, is likely to result in communication blocking or time delay, the real-time report of impact device data.In order to reduce this impact,
During intelligent docking, use scene definition following tactful according to Practical Project:
First it is ensured that real time data has precedence over historical data；
Secondly it is ensured that downlink data has precedence over upstream data.
Therefore, wireless transmission gateway first has to determine whether historical data, and specific algorithm is as follows:
Maximum data packet mtu that the definition of this system allows is l, and statistics continuously reaches number m of the bag of l.It is continuous for defining m
Receive the threshold value that packet reaches the number of bag of greatest length l.Work as m > m, then judge that this equipment has historical data to upload.
On the basis of determining whether there is historical data, in order to realize above-mentioned two strategies, specific algorithm is as follows,
1st, in the case of bandwidth anxiety, if there being historical data, it is used for data buffer storage, Zan Bufa in local opening space
Send, the allocated set Connection Release is distributed to other real-time devices and uses；Until when bandwidth occupancy takes it easy, phase of reallocating
The set answered connects, and the data is activation by buffer area.
2nd, in the case of bandwidth anxiety, if not having historical data, it is used for the big data of time delay in local opening space
