Embodiment Construction

[0017]Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0018]It is an object of the present invention to make a protocol conversion gateway for a case where the current converter station cannot operate in the station communication router. In this protocol conversion gateway, the SNMP pre-program and IEC 60870-5-104 protocol (referred to as 104 protocol forwarding program) are used as an example, and the protocol conversion gateway is docked with the operation display system, and the operation display system in this embodiment For the HMI monitoring system. The gateway collects management by the SNMP-based SNMP program (network port status, router CPU load and memory usage, etc.), and then transmits the router through the IEC 60870-5-104 protocol. Status information is accessed to the HMI monitoring system.

[0019]Such asfigure 1 As shown, the programs in the protocol conversion gateway are overview:

[0020]SNMP pr...

Abstract

The invention relates to a protocol conversion gateway, which belongs to the technical field of direct current transmission control and protection, and includes a collection interface used to connect to a router, a forwarding interface used to connect to an operation display system, a processing unit and a storage unit, and the processing unit performs storage in the storage unit The front-end program and the protocol forwarding program in the protocol, the protocol forwarding program receives the call command from the forwarding interface, the protocol forwarding program encapsulates the call command into a call command according to its configuration information, and sends the call command to the front-end program; Call the command to analyze, and send the data request command to the collection interface; the front-end program obtains the requested data from the collection interface, and sends it to the protocol forwarding program; the protocol forwarding program packs the data according to the predetermined protocol, and sends it to the forwarding interface. It solves the problem that the current DC control and protection system cannot effectively monitor the operating status of the inter-station communication router.

Description

Technical field[0001]The present invention relates to a protocol conversion gateway, which belongs to the field of DC transmission control protection technology.Background technique[0002]DC transmission system station communication is very important for stable operation of DC transmission systems. The control protection system relies on station communication to complete the joint control of the rectifier side and the inverter side, coordinate the unlocking and latching operations on both sides. However, there is currently no effective monitoring of station communication routers in the stationary station. After the maintenance personnel can only control the communication failure between the station, the main information is not timely, the fault processing is not timely, and the router operating status information is not allowed to perform real-time and efficient monitoring of the router operating status information.Inventive content[0003]It is an object of the present invention to pr...
