Problems solved by technology

[0003] However, this file-level data compression mode has poor real-time compression performance, a huge amount of computation during the compression period, and the need to decompress the entire file when retrieving it, which cannot well solve the compressed transmission of production-type time-series data.

Embodiment 1

[0040] Such as figure 1 A method for sending time series data is shown, comprising the following steps:

[0041] S1 compiling step: compile the measuring point data, the measuring point data includes time stamp, data index and data content, the data content is converted into binary by the monitoring values ​​of all measuring points under the same time stamp in the order of the pre-generated measuring point list deposit;

[0042] S2 sending step: send the compiled measuring point data.

[0043] Among them, the measuring point list includes the measuring point names and measuring point types of all measuring points to be monitored by the synchronization server, that is, before sending the measuring point data, the measuring point names and measuring point types of all measuring points corresponding to the measuring point data will be sent in advance . Usually, after the remote server receives the version number and the list of measuring points for the first time, it will cach...

Embodiment 2

[0047] Such as figure 2 A method for receiving time series data is shown, comprising the following steps:

[0048] S1 comparison step: receive the version number and the measurement point list data, and determine whether the version number and the measurement point list data have been updated, and if so, save the new version number and the measurement point list.

[0049] S2 data receiving step: receive the compiled measuring point data, the measuring point data includes time stamp, data index and data content, the data content is based on the pre-generated measuring point by the monitoring values ​​of all measuring points under the same time stamp The order of the list is converted into binary and then stored;

[0050] S3 data translation step: translate the measuring point data in sequence according to all measuring point names in the pre-saved measuring point list.

[0051] Among them, the comparison step is only performed when the synchronization server and the remote s...

Embodiment 3

[0054] Embodiment 3 discloses a time-series data synchronization server, including a memory and a processor, the memory stores executable programs, wherein one or more processors and memories can be used, the program is stored in the memory, and configured be executed by a processor, and when the processor reads and executes the program, the method for sending time-series data in Embodiment 1 is realized.

Abstract

The invention discloses a time series data sending method. The method comprises a compiling step and a sending step, wherein the compiling step comprises the step of compiling measuring point data, wherein the measuring point data comprises a timestamp, data index and data content, and monitor values of all measuring points of the same timestamp are converted into binary values according to a sequence in a pre-generated measuring point list and then are stored as the data content; the sending step comprises the step of sending compiled measuring point data. Through adoption of the time seriesdata sending method, the measuring point name and the timestamp can be sent uniformly, massive time series data can be compressed effectively, redundant data is reduced, network bandwidth is saved, and the time series data can be transmitted in a long distance.

Description

technical field [0001] The invention relates to the field of data compression transmission, in particular to a method and device for sending and receiving time series data. Background technique [0002] At present, in modern electric power, chemical industry and other industrial production, many types of real-time monitoring, inspection and equipment analysis will generate time-series data. Time series data, that is, time series data, this type of industrial data has the characteristics of fast generation frequency, many measurement points, and large data volume. Usually, the time series data of a measuring point is composed of measuring point name, time stamp, and monitoring value. A conventional real-time monitoring system has tens of thousands of measuring points, and the measuring points generate data every second, generating tens of gigabytes of data every day. The amount of data in bytes, if each measuring point needs to transmit the measuring point name and time stam...
