Abstract

The invention discloses a SCADA system provided with video feedback signals. The system comprises a SCADA server, a protocol converter and a video display terminal, wherein the protocol converter comprises an Ethernet interface, a CPU, a FLASH and a USB interface; a debugging computer is connected with the protocol converter via the USB interface; the debugging computer inputs configuration information and debugs the protocol converter; the configuration information is stored in the FLASH; the SCADA server sends SCADA signals; the SCADA signals are accessed to the protocol converter and are converted into target signals in terms of format through an RS-232 / 485 protocol; the CPU deals with the target signals; and the target signals, after processed, are transmitted to the video display terminal through the Ethernet interface. The advantages are as follows: users' requirements for linkage between a single-path video and SCADA can be realized, and positioning and focusing are accurate; a function of multi-path videos responding to one SCADA motion signal can be realized, and comprehensive data and equipment state information can be provided for users; and the information can be provided for the users in the format of a form, and at the same time the system can also associate an equipment change event with a video file.

Description

technical field [0001] The invention relates to a data acquisition and monitoring control system, in particular to a SCADA system with video feedback signals. Background technique [0002] SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control) system is a computer-based production process control and scheduling automation system, which can monitor and control the operating equipment on site to achieve data acquisition, equipment control, measurement , parameter adjustment and various signal alarm functions. [0003] However, the current SCADA monitoring system can carry out data acquisition and monitoring. However, real-time video surveillance cannot be performed. Contents of the invention [0004] The purpose of the present invention is exactly in order to solve the above problems, and a kind of SCADA system with video feedback signal is provided, and it has advantages such as accurate positioning and zooming, comprehensive data, real-...
