Description

(1) Technical field: [0001] The invention relates to a high-speed data communication system, in particular to a VC-based ADO technology high-speed parallel communication system and its working method. (two) background technology: [0002] The signal acquisition system is an important link in the detection and control of industrial objects. Only when a large amount of on-site data is collected correctly can it be analyzed and processed reasonably. There are many interface modes for connecting computers and peripheral devices: serial, USB, SCSI, parallel, etc. Each interface mode has its advantages and disadvantages. Due to the strong anti-interference ability of the serial and USB interfaces and the long transmission distance, the above two methods are often used in data communication. However, some applications, such as CCD and video data acquisition card, require short transmission distance, high transmission efficiency, and strict stability requirements. more and more. ...

AI Technical Summary

Problems solved by technology

[0003] In addition, when the computer is used for analog signal detection, it is necessary to configure an A / D conversion interface circuit. Commercial data acquisition cards are relatively expensive, and developing a set of traditional data acquisition cards requires a lot of knowledge reserves, especially when it comes to the underlying drivers. Program development is more difficult
