Abstract

The invention discloses an on-line monitoring terminal of a transformer substation. The on-line monitoring terminal comprises a single-chip microcomputer, a serial port extension module and a CAN (Controller Area Network) processor, wherein the serial port extension module and the CAN processor are connected with an input end of the single-chip microcomputer by RS485 ports; a plurality of serial port channels are arranged on the serial port extension module, and used for connecting different detection equipment; and the CAN processor is provided with at least one CAN port which is used for connecting field bus equipment. The on-line monitoring terminal can realize information integration and communication, eliminates an information island, avoids repeated construction, and lowers the power construction cost.

Description

Technical field [0001] The invention relates to an online monitoring terminal of a substation, which belongs to the technical field of microcomputer automatic monitoring and control. Background technique [0002] As the work of smart grid is in full swing, smart substations based on IEC61850 are gradually put into use. In the field of automation, its technical level has reached the international level. The current state maintenance data monitoring system provided by smart substations covers main transformer online monitoring, limited to online monitoring, contact temperature online monitoring, sulfur hexafluoride online monitoring, cable temperature online monitoring, lightning arrester online monitoring, etc. However, between the various detection systems They operate independently of each other, forming islands, and cannot achieve information integration and mutual communication. Summary of the invention [0003] Purpose of the invention: The present invention provides a substa...
