Embodiment Construction

[0048] See attached figure 1 , 2 , 3, 4, 5, 6.

[0049] The present invention adopts the method of integrated bus in the hardware structure, that is, integrates a set of parallel buses with complex synchronous control logic on the common motherboard of the system, including clock bus, control bus, state bus, timing bus and so on. Each sub-wave recorder is plugged into the motherboard through a bus plug and communicated with the motherboard bus. When working, each sub-wave recorder operates independently, and at the same time sends control commands or receives status commands through these buses to realize the coordination and synchronization of the entire system operation.

[0050]The system synchronous clock is the basis and guarantee for the normal operation and parallel synchronization of distributed oscilloscopes. Two sets of synchronous clocks are set in the present invention, wherein one set is called system clock, is designed on the motherboard, is produced by the mo...

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 of data 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...
