Synchronization method based on distributed-type integrated recorder parallel buses

Abstract

The invention belongs to the category of high-speed large-capacity data measurement and recording. By adopting methods of synchronous parallel sampling, sectionally synchronous transmission, data queue synchronization, sectionally synchronous computing, parallel synchronous recording, on-line synchronous timing and accurate marking of absolute time of sampling data, and the like, the sectional computing synchronization and the accurate synchronization recording of a plurality of sub-recorders under an asynchronous computation process in a distributed-type integrated recorder are realized. A system clock provides the guarantee for synchronous parallel sampling and sectionally synchronous transmission. Parallel buses and control circuits which are integrated on the sub-recorders and a motherboard are taken as a synchronous hardware basis. The data queue synchronization and the computing and recording synchronization can be realized by matching a queue synchronization control line and a status line, a calculation synchronization control line and a status line as well as a recording, recorded value and definite value control line and a status line with a motherboard synchronization control circuit. The method conveniently and reliably ensures the strict synchronization of data recording of the distributed-type integrated recorder and the high-resolution time precise positioning ofdata mutation or scheduled events.

Description

Technical field [0001] The invention belongs to the field of computer application, relates to a large-capacity and high-speed measurement and recording system processed by a computer, and in particular to a synchronization method based on a parallel bus of a distributed integrated wave recorder. Background technique [0002] Dynamic wave recorder is a digital high-speed measurement and recording instrument. The instrument can perform uninterrupted high-speed synchronous tracking and sampling detection of multiple fast-changing related signals connected externally, so as to capture the instantaneous abnormality, sudden change or occurrence of a specific event of the detected signal, and then analyze all related signals as required Real-time dynamic recording and analysis. Because this instrument can track and record multi-parameter systems for a long time, and automatically capture and find faults or abnormalities of the detected system, it has been widely used in scientific...

Problems solved by technology

The distributed integrated wave recorder breaks through the capacity and bandwidth limitations of the traditional master-slave wave recorder and overcomes the shortcomings of too concentrated risks

However, the difficulty in the implementation of distributed integrated wave recorders lies in how to ensure the data synchronization of multiple sub-wave recorders that are distributed and working in parallel, that is, sampling synchronization, transmission synchronization, queue synchronization, calculation synchronization, and wave recording synchronization
