Abstract

The invention provides a virtual analog-to-digital conversion core device which is used for acquiring data and providing the data for a primary device for control or protection. The core device comprises a virtual analog-to-digital conversion port. The core device sends target sampling data messages containing data which is sampled synchronously by the master clock of the primary device to the primary device by virtue of the virtual analog-to-digital conversion port. The virtual analog-to-digital conversion port comprises serial ports. According to the core device, the time synchronization is used for replacing straight line connection on hardware, thus reducing the cost of constructing a remote industrial control system greatly.

Description

Technical field [0001] The present invention relates to a core device, in particular to an IEEE1588 Ethernet-based virtual analog-to-digital conversion core device applied to an industrial measurement and control system. Background technique [0002] The measurement and control system for industrial applications is usually used to collect and monitor the data of on-site operation. Through the analysis and statistics of the sampled data, corresponding strategies are adopted to achieve control, protection, or measurement. The point-to-point serial connection between devices in the traditional measurement and control system is achieved through cables, which will undoubtedly lead to high hardware costs and cause a lot of trouble for remote protection and control or system expansion. With the rapid development of computer chips and network communication technology, traditional measurement and control systems have begun to use network communication technology to realize the interaction...
