Background
With the development of the internet and terminal equipment, more and more terminal equipment need to be accessed into the network to realize real-time information communication; for example: data exchange between each App on the mobile phone and the server side, and automatic uploading of data of various hardware devices such as an ammeter, a water meter and the like; whether the monitoring device is on-line heartbeat detection, and the like. These terminal devices need to perform heartbeat communication with the server for a long time to ensure whether the devices are online or obtain the latest messages. At present, most terminals send data according to a set interval time in terminal equipment, and then a server end feeds back a specific service data response.
With the popularization of more and more terminal devices, especially the subsequent 5G communication technology, a large number of terminal devices surf the internet; if the terminal equipment sets the interval length for sending the data once without a unified management method for interval sending time, the situation that a server end receives a large number of requests in a certain time period may occur; and in other time periods, an idle condition occurs. In this case, the bandwidth of the network where the server is located may be suddenly higher or lower. When the server receives a large number of requests, the processing pressure is too large, and the possibility of downtime is caused; when the idle state occurs, the traffic is too small to be reasonably utilized; therefore, there is a need for a method for uniformly managing the request sending time of each terminal without affecting a large amount of data requests, so that each terminal device sends data in a uniformly distributed time, thereby realizing reasonable utilization of bandwidth and server resources.

Drawings
The invention is further described below with reference to the accompanying drawings:
FIG. 1 is a flow chart of the method of the present invention.
Detailed Description
As shown in FIG. 1, the basic process of the method of the present invention is as follows:
step 1: constructing a hierarchical interval time range list based on the data importance degree and the historical data of the terminal equipment, wherein the hierarchical interval time range list is used for acquiring the interval time range of each subsequent terminal equipment;
constructing a hierarchical interval time range list, wherein the key point is that an interval time range list which is reasonably distributed according to the importance degree of a service is formed based on data and historical data of each communication; the method mainly comprises the following steps:
1) and analyzing the communication types of the whole terminal equipment and the server side, wherein one communication type forms a hierarchical interval time range table.
2) In a communication type range, analyzing the feedback delay time distribution condition of each device in the original time of sending at regular device intervals based on historical data; and setting the hierarchy of interval time according to the delay distribution condition and the number of the terminal equipment. For example, if the total number of terminal devices is large for a delay time within 500 ms, the interval time may be set longer and the interval range may be set larger, so that more devices are accommodated in the time range. In a certain delay time, the related devices are less, the interval time can be set to be shorter, and the interval range is smaller, so that the high-frequency communication can be rapidly carried out with the devices, and the communication condition of the devices can be confirmed.
3) And continuously updating the communication records of the terminal equipment and the server to form historical data. The hierarchical interval time range list is continuously analyzed according to historical data in the subsequent operation process, and is continuously optimized; a new hierarchical list of interval time ranges is formed and updated into the system.
Step 2: constructing a uniformly distributed random data acquisition method based on a certain time range, wherein the method is used for acquiring the sending time interval of each terminal device;
because the number of the terminal devices is extremely large, each communication type and each feedback delay time have a level of data sending time interval range; each terminal device needs to transmit data within uniformly distributed time as much as possible so as to avoid data concentration in a certain time period; therefore, after acquiring the time interval range of the data transmission of a terminal device, randomly acquiring the transmission time in the time range; and the random sending time needs to be the condition of uniform distribution; therefore, a uniformly distributed random data acquisition method based on a certain time range needs to be constructed.
And step 3: in the communication process of the terminal equipment and the server, three parameters are appointed: time of receipt of the information, time of interval transmission by the device, number of incorrectly received data (shown as 0 if all correctly received);
The three parameter terminals need to be initialized at the server end when sending; when the terminal device reports data, the data needs to be uploaded. In the three parameters, the time of the equipment interval transmission can store data according to 8 bits; the time of receiving the information adopts the number of milliseconds of the time, 42 bits are needed for storing the data, and 6 bytes are needed; but there are 6 bits free to hold the amount of incorrectly received data. According to the rule, only 7 bytes are needed in total, and the total data can be stored for reporting and sending. The three parameters are stored in the reporting and issuing processes, and the purpose is to save the time for inquiring the equipment in each heartbeat process through space. By exchanging time for space, the efficiency of data exchange is improved.
And 4, step 4: when data sent by terminal equipment are received, three appointed parameters are accurately acquired; if the server receives the message within the appointed time, the time of the original equipment interval transmission is fed back; adding the time of interval transmission of the equipment at the current server end; plus the number of incorrectly received data is set to 0; and simultaneously adding data information to be acquired and feeding back the data information to the terminal equipment. If the server side finds that the appointed time is exceeded after receiving the information, the interval time is adjusted to be shorter according to the rule; or if the time for receiving the information is found to be advanced, the interval time is adjusted to be longer; acquiring the time for receiving the information according to the new equipment interval sending time, setting the number of incorrectly received data to be 0, and sending the incorrectly received data to the terminal equipment again;
And 5: after receiving the information, the terminal equipment sends data to the server again according to the equipment interval sending time in the three appointed parameters in the appointed time interval, and meanwhile, the time of receiving the information and the number of incorrectly received data of the server are added;
and the server side directly acquires data to judge whether errors exist in the feedback of the process, wherein the errors comprise delay or advance. The delay shows that the network is unstable, and the terminal equipment is required to improve the frequency of sending data so as to ensure the normal connection of the data and the server side. The network is normal and stable in advance, so that the equipment can transmit data at a lower frequency, and the data transmission quantity is reduced. Therefore, the self-adaptive terminal equipment of the whole system sends data according to different intervals according to the error degree of the information received by the server. When the terminal equipment sends data, the stable condition of the network where the terminal equipment is located is distinguished, and the uniform utilization of the server network and resources is achieved.
Step 6: continuously adjusting the interval sending time of each device based on the information receiving time, the interval sending time of the devices and the number of incorrectly received data in the steps 4 and 5; under the condition of normal network, a large amount of equipment is used, and the time interval level of the sending data is continuously adjusted in a self-adaptive manner, so that the uniform time distribution of the sending data of the large-specification terminal equipment is realized, and the reasonable utilization of network bandwidth and server resources is realized.
After the relevant foundation is built through the steps 2, 3 and 4, the service is mainly initiated by the terminal equipment, and the flow of the whole service is realized according to the following steps:
1) the terminal equipment initiates a request, and in the carried information, because the three agreed parameters are null, no related information exists;
2) after receiving the request initiated by the terminal device, the server side acquires the first default data (with the shortest interval time) in the interval time range list of the hierarchy in the communication types because the three agreed parameters are null. In the interval range, acquiring the interval time of the next sending request by a uniformly distributed random data acquisition method; initializing the time required to acquire the time sent by the terminal equipment next time by using the random number, setting the number of incorrectly received data to be 0, and returning the number to the terminal equipment;
3) after receiving the information returned by the server, the terminal equipment acquires the interval time for sending the request; and timing when receiving the information, and sending a piece of data after the interval time of the sending request is reached. The data carries the interval time of the sending request, the time required to obtain the sending time of the terminal equipment next time and the number of the incorrectly received data, and the data is returned to the server side.
4) And after the server correctly receives the time interval with the data transmission, the time required to be transmitted by the terminal equipment next time and the number of incorrectly received data, acquiring the time required to be transmitted by the terminal equipment next time, comparing the time required to be transmitted by the terminal equipment next time with the system date of the current server side, and calculating an error. And acquiring the next data transmission interval time in the hierarchical interval time range list through the error. And simultaneously, the original received data transmission interval time is used, and the original data transmission interval time is obtained in a hierarchical interval time range list. If the former and latter time ranges are the same, initializing the time required to acquire the time transmitted by the terminal equipment next time according to the original data transmission interval time; and sets the number of incorrect receptions to 0 and returns. If the interval time range of the sending data obtained by the error is inconsistent with the original interval time range of the sending data, adding 1 to the number of the incorrectly received data; if the number of incorrectly received data does not reach a certain threshold, for example 10 times; then, the time required to acquire the time sent by the terminal device next time is initialized according to the original data sending interval time. And returns the number of incorrectly received data, which has been added by 1, to the terminal device together. If the number of incorrect receptions reaches a certain threshold value, acquiring a latest transmission data interval time by a uniformly distributed random number generation method within a transmission data interval time range acquired by errors; generating the time required to acquire the time sent by the terminal equipment next time according to the latest data sending interval time; and sets the number of incorrect receptions to 0 and returns to the terminal device.
5) After receiving the issued information, the terminal equipment receives and acquires the sending request interval time again, and returns the sending request interval time, the time required to acquire the sending time of the terminal equipment next time and the number of incorrectly received data to the server side again after the appointed time; repeating the business process of the step 4) again.
6) The whole service process mainly directly obtains data at a server end to judge whether errors exist in feedback of the process, and if the number of the errors does not exceed the originally set interval time of sending requests, the original interval time of sending requests is continued to send data requests; if the error quantity exceeds the original time, the latest sending request interval time is acquired in a self-adaptive mode; and updating the interval time of the latest sending request, and continuously optimizing.

4) after the server correctly receives the time interval with the data transmission interval, the time required to be acquired next time and the quantity of incorrectly received data, the time required to be acquired next time and transmitted by the terminal equipment is acquired, and is compared with the system date of the current server side to calculate the error; acquiring next data transmission interval time in a hierarchical interval time range list through errors; meanwhile, the original received data transmission interval time is used, and the original data transmission interval time is obtained in a hierarchical interval time range list; if the former and latter time ranges are the same, initializing the time required to acquire the time transmitted by the terminal equipment next time according to the original data transmission interval time; setting the number of incorrect receptions to be 0, and returning; if the interval time range of the sending data obtained by the error is inconsistent with the original interval time range of the sending data, adding 1 to the number of the incorrectly received data; if the number of the incorrectly received data does not reach the set threshold value; initializing the time required to acquire the time sent by the terminal equipment next time by using the original data sending interval time; and returning the number of the incorrectly received data added with 1 to the terminal equipment; if the number of incorrect receptions reaches a set threshold value, acquiring a latest transmission data interval time by a uniformly distributed random number generation method within a transmission data interval time range acquired by errors; generating the time required to acquire the time sent by the terminal equipment next time according to the latest data sending interval time; setting the number of incorrect receptions to 0, and returning to the terminal equipment;
5) After receiving the issued information, the terminal equipment receives and acquires the sending request interval time again, and returns the sending request interval time, the time required to acquire the sending time of the terminal equipment next time and the number of incorrectly received data to the server side again after the appointed time; repeating the business process of the step 4) again.
