Problems solved by technology

Whether it is sliced ​​or not sliced, file storage is a centralized storage method, that is, the collected materials are directly incorporated into the network storage system, and a large amount of storage space is provided for material storage through the online disk array. However, once the connection to the network occurs failure, it may lead to failure to write files directly on the disk array in the network, thus making the entire included files scrapped

Embodiment Construction

[0038] Such as figure 2 Shown, a kind of file dumping system in the real-time data acquisition process, this system comprises recording module 11, proxy module 14, local memory 13, dumping module 15 and target memory 16;

[0039] The recording module 11 is used to store the data collected from the data source 12 into the local memory 13 designated by the user, and when the recording module 11 completes the recording of the local file, the agent module 14 is notified of the information;

[0040] The agent module 14 is configured to send the received file information transmitted by the recording module 11 to the dump module 15;

[0041] The dump module 15 is configured to accept the file information transmitted by the agent module 14, and dump the files in the local storage 13 into the target storage 16;

[0042] The local memory 13 is used to store data from the recording module 11;

[0043] The target storage 16 is used to store data required by the user, and the target sto...

Abstract

The invention discloses a file dumping method and a system in a process of real-time data acquisition, belonging to the technical field of data storage. When the prior real-time data acquisition system acquires mass data, data from a data source is directly stored in a target memory, thus the requirements to network environment where the system locates and a disk system are extremely high, however, due to the complexity of software and hardware of a computer network system, the safe and reliable network environment not only needs enormous investment, but also can not prevent accidents from happing completely. In the method and the system of the invention, data received by a receiving and recording module is firstly stored in a local memory, and then, the data stored in the local memory isdumped into the target memory by a dumping module, thereby improving the stability and the fault-tolerant capability when the real-time data acquisition system acquires mass data.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a file dumping method and system in a real-time data collection process. Background technique [0002] Today, with the rapid development of digital technology, in the field of radio and television, its recording system can receive multiple sets of programs from multiple satellites, and can download at the same time, and automatically collect TV programs on each satellite. It is an important means for units to obtain program materials and conduct program exchanges. [0003] The recording control system realizes automatic multi-channel recording and batch collection functions. Users only need to formulate a program collection task form according to work needs, and the system automatically collects according to the time and content specified in the form every day. The front-end input of the recording system supports various analog video and audio interfaces (analog...
