Embodiment 1

[0015] Such as figure 2 As shown, the channel tag-based data transmission device provided in this embodiment has 5 channels such as figure 1 The BISS module 3 shown packs the collected data inside each BISS module 3 (add the channel mark and time stamp to the data packet), and the channel that completes the collection and packing first is reported to the data transmission control Module 1, which is temporarily stored by the data transmission control module 1, and finally transfers the data as a whole to the FIFO memory 2.

[0016] An internal collection cycle sends 5 channels of data to the FIFO memory 2 once. The receiving and sending of the data transmission control module 1 are parallel, as long as it is not in the reset state, it has been receiving. This channel sends all 0 data.

[0017] The data in the FIFO memory 2 is not stored in the order of channels. After receiving the data, the user needs to unpack the data packet, read the internal channel data, and store it i...

Abstract

The invention provides a data transmission apparatus based on channel labeling, and belongs to the technical field of data synchronization communication. The apparatus comprises a data transmission control module, a FIFO memory and multiple BISS modules used for performing the channel labeling on data, wherein each BISS module is connected with the FIFO memory through the data transmission control module. According to the invention, corresponding channel labels are added multiple BISS core data, no matter which channel completes current period data acquisition, the data can be directly transmitted to the data transmission control module so as to be transmitted to the FIFO memory, the data is neither controlled or ordered inside the data transmission control module, only a bridge effect of parallel to serial connection from the multiple BISS modules to the same FIFO module is exhibited, and thus board internal delays caused by manual control and ordering are substantially shortened.

Description

technical field [0001] The invention relates to a data transmission device based on a channel mark, belonging to the technical field of data synchronous communication. Background technique [0002] In the field of data acquisition, there are a variety of communication protocols for acquisition. With the development of science and technology, BISS-C (Bidirectional Synchronous Serial, bidirectional synchronous serial interface) protocol has gradually become a mainstream. [0003] In the application process of the existing board based on the BISS-C protocol, due to the poor synchronization of the collected data of each channel, the time difference between channels is often more than 40 μs, which leads to a large internal delay of the board. Contents of the invention [0004] The present invention provides a data transmission device based on channel marking to solve the problem that the existing BISS-C protocol-based boards have relatively large internal delays during the app...
