Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the invention is described in further detail.Hereinafter implement
Example is not limited to the scope of the present invention for illustrating the present invention.
It is the broadcasting and TV frequency spectrum ultra-narrow band Internet of Things communication channel rate self adaptation side of one embodiment of the invention referring to Fig. 1
Method, including：S1, upper level equipment transmission data receives the reception data success of next stage equipment feedback to next stage equipment
Response message；S2, according to the reception successful response message of data, calculates the current receiving velocity of next stage equipment；
S3, according to the current receiving velocity of next stage equipment, adjusts the currently transmitted speed of upper level equipment, and with the speed after adjustment
Send next batch data.
In the data transmission procedure of communication system, if sending the upper level equipment of data and receiving the next stage of data
The transmission rate difference of equipment is very big, and data spilling or the state of free time, the data transfer mistake of whole communication system just occurs
It is not sufficiently stable in journey, accordingly, it would be desirable to the transmission rate of real-time adjustment communication system.
The present embodiment is when upper level equipment transmission data is to next stage equipment, and it is anti-that upper level equipment receives next stage equipment
The successful response message of reception data of feedback.The response message that upper level equipment is fed back according to next stage equipment, calculates next
The current receiving velocity of level equipment.Then according to the current receiving velocity of next stage equipment, to the currently transmitted speed of itself
It is adjusted so that the currently transmitted speed of upper level equipment can so be protected close to the current receiving velocity of next stage equipment
Demonstrate,prove the stability and reliability during whole communications system transmission.
In one embodiment of the invention, the step S2 also includes：
If upper level equipment is not received by the response message of next stage equipment in Preset Time, upper level equipment is still
So with currently transmitted speed, downward first device sends identical data again, the reception until receiving next stage equipment feedback
The successful response message of data.
When the downward first device of upper level equipment sends data, upper level equipment is not received by within the default time
The successful response message of next stage equipment receiving data, is now likely to network and goes wrong.This when, upper level equipment
Need to retransmit again, the successful response message of data receiver until receiving next stage equipment feedback, upper level equipment ability
According to the response message that next stage equipment is fed back, the current receiving velocity of next stage equipment can be calculated.
In another embodiment of the present invention, the step S3 is specifically included：
S31, if the currently transmitted speed of upper level equipment is more than the current receiving velocity of next stage equipment, reduces upper one
The currently transmitted speed of level equipment；

The currently transmitted speed of level equipment.
Upper level equipment is calculated after the current receiving velocity of next stage equipment, and upper level equipment is according to next stage equipment
Current receiving velocity, the currently transmitted speed adjust of itself is approached to the current receiving velocity with next stage equipment, it is ensured that
The reliability service of whole communication system.
In one embodiment of the invention, the step S31 is specifically included：
During the upper level equipment currently transmitted speed of reduction, if currently transmitted speed reaches next stage equipment most
During small receiving velocity, next stage equipment is notified.
If above embodiments illustrating the current reception speed of the currently transmitted speed more than next stage equipment of upper level equipment
Rate, then reduce the currently transmitted speed of upper level equipment.Process of the present embodiment in the upper level equipment currently transmitted speed of reduction
In, it is reduced to the minimum receiving velocity that minimum speed cannot be below next stage equipment.If the transmission rate of upper level equipment is low
In the minimum receiving velocity of next stage equipment, then the currently transmitted speed of upper level equipment can not possibly be current with next stage equipment
Receiving velocity is equal, therefore, the minimum minimum reception that can only be reduced to next stage equipment of the current receiving velocity of upper level equipment
Speed.
The step S32 is specifically included：
During upper level equipment improves currently transmitted speed, if currently transmitted speed reaches next stage equipment most
During big receiving velocity, next stage equipment is notified.
Likewise, during upper level equipment improves currently transmitted speed, bring up to highest speed not above
The maximum receiving velocity of next stage equipment.If the transmission rate of upper level equipment is higher than the maximum receiving velocity of next stage equipment,
Then the currently transmitted speed of upper level equipment can not possibly be equal with the current receiving velocity of next stage equipment, therefore, upper level sets
Standby current receiving velocity only up to bring up to the maximum receiving velocity of next stage equipment.
