Method for performing fusion storage on low-speed serial data and high-speed collection data

Abstract

The invention discloses a method for performing fusion storage on low-speed serial data and high-speed collection data. The method comprises the steps that 1, initialization setting is performed on adata collection and storage system; 2, a master control module sends the high-speed collection data to a collection and storage module; 3, the master control module sends the low-speed serial data tothe collection and storage module; and 4, the collection and storage module performs fusion storage on the low-speed serial data and the high-speed collection data. The method can meet the applicationdemand of serial online asynchronous update and adapt to sending of a new parameter list by the master control module at any moment in any cycle, the new parameter list can be updated to a frame header of each data fusion frame to be sent into a storage space with minimum time delay, and the information completeness of the parameter list is ensured. The method also achieves the function of performing reliable fusion storage on the low-speed serial data and the high-speed collection data, and the data instantaneity, completeness and reliability of data collection and storage equipment are effectively improved.

Description

technical field [0001] The invention relates to asynchronous data fusion technology, in particular to a method for fusing and storing slow serial port data and high-speed collected data. Background technique [0002] The data acquisition system needs to be compatible with a variety of interfaces with different rates, low rate such as serial port (less than or equal to 1Mbps), high rate such as 4X optical port (greater than or equal to 1Gbps, less than or equal to 10Gbps). Among them, the serial port is usually used for the main control module of the system to send the parameter list to the acquisition and storage module, such as frame header, frame length, data channel number, data type and other important information for information extraction, data analysis and algorithm verification. Although the update rate of such information is slow and the amount of data is small, it must be completely stored along with the original acquisition data of each frame acquired by the syste...

[0006] 2. In a distributed system, it is very easy to have the obvious disadvantage of time scale asynchronous, especially in many application environments, the data interface rate has reached 10Gbps, and the time accuracy is extremely high. Even in a synchronous system, it is processed at a GHz-level clock frequency Packing data, it is also very difficult to synchronize the data of the asynchronous interface, and the data reliability is at risk
