Embodiment 1

[0038] This embodiment provides a real-time calculation method based on multi-device out-of-order data, such as figure 1 As shown, the steps of the real-time calculation method based on multi-device out-of-sequence data specifically include:

[0039] Step 101, the real-time database collects real-time data from multiple devices respectively.

[0040] The real-time database collects and stores real-time data from multiple devices during the current read cycle.

[0041] Step 102, read the real-time database with a preset reading cycle, and for each reading cycle, acquire the latest real-time data of multiple devices within the time range of the current reading cycle.

[0042] At the end of the current reading cycle, the real-time database collects all the latest real-time data that needs to be calculated in real time.

[0043] Step 103: Perform calculation on the latest real-time data according to a preset algorithm to obtain a calculation result.

[0044] For the latest real...

Embodiment 2

[0053] This embodiment provides a real-time calculation method based on multi-device out-of-order data. Compared with Embodiment 1, this embodiment has Figure 4 As shown, the difference is that after step 102, it also includes:

[0054] Step 102', judging whether the latest real-time data of each device has been obtained in the current reading cycle, if not, then execute step 103', if so, execute step 103.

[0055] Step 103', use the latest real-time data in the time range of the previous reading cycle of the device that has not obtained the latest real-time data as the latest real-time data in the current reading cycle, and continue to execute step 103.

[0056] For the real-time data not collected in the time period of the current reading cycle, the real-time data collected in the previous reading cycle is used for calculation to obtain the operation result.

[0057] like Figure 5 As shown, it can be seen that MORRESULT did not collect the real-time data of the device MO...

Embodiment 3

[0066] This embodiment provides a real-time computing system based on multi-device out-of-order data, such as Figure 7 As shown, the real-time computing system based on multi-device out-of-order data includes a collection module 201 , a reading module 202 and a computing module 203 .

[0067] The collection module 201 is used to collect real-time data from multiple devices respectively by using a real-time database.

[0068] The reading module 202 is used to read the real-time database with the preset reading cycle, and for each reading cycle, obtain the latest real-time data of multiple devices within the time range of the current reading cycle; when the current reading cycle ends, real-time The database collects all the latest real-time data that needs to be calculated in real time.

[0069] The calculation module 203 is used to perform calculations on the latest real-time data according to preset algorithms to obtain calculation results.

[0070] For the latest real-time...

Abstract

The invention discloses a real-time computing method and system based on multi-device out-of-order data. The real-time computing method based on the multi-device out-of-order data comprises the stepsthat a real-time database collects the real-time data from multiple devices; the real-time database is read in a preset reading period, and for each reading period, the latest real-time data of multiple devices in the time range of the current reading period are obtained; and operation is carried out on the latest real-time data according to a preset algorithm to obtain an operation result. According to the invention, by setting the reading period and reading the real-time database in a reading period, obtaining the latest real-time data collected from a plurality of devices within a current reading period, and taking the acquired latest real-time data of the multiple devices as the same timestamp data to be calculated, the problem of real-time data disorder is solved, the time consistencyof the data disorder of the multiple devices is kept, and the latest real-time data of the same timestamp can be simply and conveniently calculated according to the preset algorithm to obtain the calculation result.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a real-time computing method and system based on multi-device out-of-order data. Background technique [0002] With the development of the process industry, a large amount of high-frequency measurement data needs to be stored in real time, and if the traditional relational database is used again, it is difficult to meet the high requirements of data real-time storage speed and storage capacity, and the application requirements for real-time data and real-time transactions have become Difficult to do. [0003] Therefore, a real-time database suitable for the field of industrial monitoring emerges as the times require. The real-time database has a time-scaled data structure and high-frequency caching technology designed for fast reading and writing, which can realize millisecond-level reading and writing of massive data. In addition, based on the compression algorithm and the speci...
