According to Fig. 1 to Figure 13, illustrate the embodiment of the present invention in a first aspect, a kind of Internet of Things communication means, such as Fig. 1 institutes
Show, is applied to server, including：
The required first time T1 of connection request that S101, acquisition are sent with current thread operating mode processing terminal；
S102, judge whether first time T1 reaches first time threshold, if first time T1 reaches first time threshold,
Then follow the steps S103；
S103, switching current thread operating mode.
In the present embodiment, current thread operating mode is the thread work residing for server when obtaining first time T1
Pattern；Thread work pattern includes：Single thread operating mode and multithreading operating mode.If current thread operating mode is single line
Journey operating mode, switching current thread operating mode are to switch to multithreading operating mode by single thread operating mode；If working as
Preceding thread operating mode is multithreading operating mode, and switching current thread operating mode is to be switched to by multithreading operating mode
Single thread operating mode.
Server in this method can be according to the traffic load amount of internet-of-things terminal (hereinafter referred to as " terminal ") in single thread
Flexibly switch between operating mode and multithreading operating mode, improve server process connection request ability, make server with
The communication of terminal is more efficient.
First time T1, which is reflected, to give out a contract for a project time-consuming between terminal and server, that is, reflects the communication efficiency of communication system,
First time, T1 was bigger, indicated that the communication between terminal and server more has some setbacks, the efficiency of communication system is lower；Lead to first
The increased factors of time T1 mainly have following two aspects：1) traffic load between terminal and server is big；Such as in certain a period of time
Between there are 300 terminal to server to have sent a large amount of connection requests in section, and the Thread Count of server process connection request is limited,
Such as 60 threads, 60 connection requests can only be once handled, other 240 connection requests are just waited in line, thus, right
For other 240 connection requests waited in line, time for waiting in line is included in give out a contract for a project and take in, become so giving out a contract for a project and taking
Greatly, i.e. first time T1 increases；Such as the traffic between terminal and server becomes larger, then the time for handling a connection request becomes
Long, the Queue time for the connection request being lined up is also corresponding elongated, and causing to give out a contract for a project to take becomes larger, i.e. first time T1 increases
Greatly；2) the performance in-fighting of server is big；Such as although the connection request of pending terminal is less, server is still dispatched greatly
The thread of amount handles less connection request, and the processor of server needs to be scheduled these thread, processor exists
A thread can only be executed in one timeslice, for switching to thread B by thread A, processor needs " to preserve thread A's
Execute scene ", then " be loaded into thread B executes scene ", this process can consume the resource of a large amount of processor, server
The quantity of the thread of processor scheduling is bigger, and the resource of the processor of consumption is more；The consumption of switch threads also has：Memory it is same
Walk expense, thread creation and the expense of extinction and the expense etc. of scheduling；Server is consumed to the handoff procedure of thread
The efficiency of resource, server process connection request is lower, and giving out a contract for a project to take increases, and first time T1 increases.In short, what terminal was sent
The load capacity of connection request and the treatment progress number of server mismatch, and increase first time T1.When server process thread
When less, by taking current thread operating mode is single thread operating mode as an example, first time T1 increases, and reaches first time threshold
When, illustrate that the thread of server work is very little, be not enough to cope with excessively high traffic load, needs to work in increase server at this time
Thread Count, switch current thread operating mode, i.e., multithreading operating mode is switched to by single thread operating mode；Work as server
When the thread of middle work is excessive, by taking current thread operating mode is multithreading operating mode as an example, first time T1 increases, and reaches
When first time threshold, illustrate that the thread of server work is too many, Thread-switch overhead is too big, needs to reduce in server at this time
The Thread Count of work switches current thread working condition, i.e., switches to single thread operating mode by multithreading operating mode.Pass through
Change the Thread Count to work in server, it is ensured that the traffic load of server and the Thread Count of work match, the clothes made
The connection request that the efficient processing terminal of business device is sent, and then the communication between the terminal of Internet of Things and server is made more to increase
Effect.
Multithreading operating mode in the present embodiment includes the multithreading operating mode of 2 threads and the above thread.In turn,
In a kind of optional embodiment, multithreading operating mode includes the first multithreading operating mode, the second multithreading operating mode, the
Three multithreading operating modes and the 4th multithreading operating mode.If the maximum thread that server is configured is N, more than first
The Thread Count dispatched in thread work pattern is N/4, and the Thread Count dispatched in the second multithreading operating mode is N/2, and third is more
The Thread Count dispatched in thread work pattern is 3N/4, and the Thread Count dispatched in the 4th multithreading operating mode is N.It is corresponding,
Traffic load is minimum or the communication request number of terminal is few, or even only there are one terminals when sending communication request, and server is cut
Single thread operating mode is shifted to, i.e. the current thread operating mode of server is single thread operating mode；With traffic load
It gradually increases, current thread operating mode can be switched to the first multithreading operating mode or the second multithreading operating mode, or
Third multithreading operating mode or the 4th multithreading operating mode.
Further multithreading operating mode is finely divided, in a kind of optional embodiment, the work of each different threads number
Operation mode one multithreading operating mode of equal self-contained, i.e. multithreading operating mode include 2 thread work patterns, 3 thread work moulds
Formula, 4 thread work pattern ... N-1 thread works patterns and N thread works pattern (total number of threads of server is N).For
Specific traffic load, server only work under the operating mode of optimal Thread Count, just can guarantee that communication system is in most
Efficient communications status.As shown in Fig. 2, when traffic load is minimum, i.e., when single thread operating mode can meet communication requirement,
With the increase of the Thread Count to work in server, the switching consumption of server thread increases, and the working efficiency of communication system is anti-
And it continuously decreases；As shown in figure 3, when traffic load is in the maximum value that communication system can accommodate, with work in server
The increase of the Thread Count of work, the connection request waited in line is fewer and fewer, and the working efficiency of communication system gradually increases；Such as Fig. 4
It is shown, when traffic load is between peak volume and minimum traffic, with the increase of the Thread Count to work in server,
Showing that the connection request waited in line is fewer and fewer, the communication efficiency of communication system improves, to after critical value, the line in server
Journey switching consumption becomes apparent, and the communication efficiency of communication system continuously decreases.By the above rule, server is according to traffic load
Corresponding multithreading operating mode is switched to, ensures that the communication efficiency of communication system is in optimum state.
First time threshold reflects the desired value to the communication efficiency of communication system, and first time threshold is smaller, explanation
It is expected that the communication efficiency of the communication system is higher；First time threshold is bigger, illustrates it is expected that the communication efficiency of the communication system is got over
It is low.Under normal circumstances, first time threshold is positively correlated with a communication cycle, and a communication cycle, that is, terminal and server are complete
At once communicating required average time.It should be noted that with the increase of the traffic load in communication system, communication system
The optimal communication efficiency of system continuously decreases.That is, the increase of the traffic load with communication system, terminal are complete with server
The period needed at primary communication is elongated, therefore needs accordingly to tune up first time threshold.
Thread switching consumption server performance, likewise, switch threads operating mode can also consume a large amount of server
Energy：Switch threads operating mode means that total number of threads changes, wherein creating thread process or terminated line comprising a large amount of
Journey process.To avoid the thread work pattern of server from carrying out unnecessary switching, in a kind of optional embodiment, when first
Between after T1 reaches first time threshold, before switching current thread operating mode, further include：Judge current thread operating mode
Whether the duration reaches second time threshold；If first time T1 reaches first time threshold, and current thread operating mode
Duration have reached second time threshold, then switch current thread operating mode.If current thread operating mode continues
Time less than second time threshold, just switch threads operating mode again, then last time switch threads operating mode and this cut
The interval time for changing current thread operating mode is too short, and thread work pattern switching is excessively frequent, can continuously consume server
A large amount of resource, to delay the connection request of server to process terminal transmission, to reduce the communication efficiency of communication system.Institute
After the duration of current thread operating mode reaches second time threshold, then to switch current thread operating mode, to subtract
Influence of the switching current operation mode to communication efficiency less.Switching current thread operating mode in the present embodiment, if referring to
Current thread operating mode is single thread operating mode, then switches to multithreading operating mode by single thread operating mode；If working as
Preceding thread operating mode is multithreading operating mode, then switches to single thread operating mode by multithreading operating mode.
In a kind of optional embodiment, second time threshold is that the communication efficiency after switch threads operating mode reaches stable state
The required time.After switch threads operating mode, the ability of server process traffic load changes, i.e. communication system at this time
Communication efficiency change, that react communication efficiency is first time T1, in order to improve accuracy, it is preferred that at the first time
T1 be the required average value of server process connection request, so, after switch threads operating mode, immediately obtain first
Time T1 is influenced by preceding thread operating mode, is inaccurate, if at this time according to first time T1 switch threads work
Operation mode can not only influence communication efficiency, but also can not switch to accurate thread work pattern, can not ensure communication system
Communication be in highest effect state.So after the duration of thread work pattern reaching second time threshold, i.e. communication system
After the communication efficiency of system becomes stable, then switch threads operating mode, it is ensured that accurate thread work pattern is switched to, is protected
Demonstrate,prove the communication efficiency highest of communication system.
