Embodiment Construction

[0020] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Depend on figure 1 As shown, an embedded remote real-time recording system includes an FPGA data acquisition module, a forwarding module, a network module, and a recording module. The FPGA data acquisition module collects external channel data, and can simultaneously collect multi-channel data, with a maximum of 128 channels. The FPGA data acquisition module opens up 2K buffer space for each channel, and buffers the data of channels with different frequencies into the lowest frequency of 50Hz for circular buffering, and then triggers the forwarding module to read data through the 50Hz interrupt. FPGA checks the data status of each channel before each interrupt is triggered, and then fills the status value for each status address according to the check result. After the interrupt is triggered, the forwarding module first...

Abstract

The invention relates to an embedded remote real-time recording system. Aiming to solve the problems that existing real-time recording systems cannot process multi-frame-frequency data effectively and original data are inconvenient to acquire and difficult to search and preview during data processing afterwards, a method of adopting a hardware cache and soft integration technology, recording and acquiring the original data and frame-extracted data synchronously and combining data recording with recording states is provided and implemented, so that synchronous acquiring and recording of multichannel multi-frame-frequency original data are achieved effectively, functions such as real-time data monitoring, previewing and multiple searching during data processing afterwards are achieved, system compatibility, fault tolerance, maintainability and expansibility are improved, and the method is more applicable to engineering application .

Description

technical field [0001] The invention relates to the field of digital signal communication and processing, in particular to an embedded remote real-time recording system, which is mainly used for remote data recording of each unit of an external control system. technical background [0002] At present, in the fields of industrial automation production, aerospace equipment, medical systems, etc., due to the increasing demand for post-event data processing, recording systems have been widely used, and the technology is relatively mature. Many manufacturers have provided solutions and solutions for corresponding application scenarios. product. The recording system as a whole can be divided into two categories: local recording and remote recording. Local recording usually uses an embedded controller, which has limited operations on the disk and is difficult to maintain; remote recording is to transmit data to the control room remotely. The second is to facilitate the maintenanc...
