Problems solved by technology

However, the technical solutions disclosed in the above patents can no longer meet the requirements of the current smart grid
Moreover, the current encryption machine access can only achieve stand-alone interaction, and the local load encryption machine dynamic link library single-machine call access
Due to the huge resources of the State Grid, there is currently a serious shortage of encryption machines. If the resources cannot be effectively shared, it will cause huge cost waste

Abstract

The invention relates to a system for sharing and accessing a power grid encryption machine based on Remoting software architecture and intelligent electric meter parameter updating method for the system for sharing and accessing the power grid encryption machine based on the Remoting software architecture. The system comprises a front-end processor, the encryption machine, a client-side and an intelligent electric meter, wherein the front-end processor is connected with the encryption machine and communicated with the encryption machine and is interactive with the client-side to finish the identity safety certificate process of the intelligent electric meter. The client-side is connected with the intelligent electric meter and performs on-line reading and programming to the intelligent electric meter. The front-end processor and the client-side invoke a remote object interface through the Remoting software architecture and share and use the encryption machine. Resources provided by Chinese electric power research institute in state power grid construction are maximally shared. A power supply network electric quantity information acquiring system safely enciphers data and interactively processes and uses the data and enables state power netlist production to get rid of the difficulty lack of the encryption machine, the operation is convenient, and production, operation and asset management are facilitated.

Description

technical field [0001] The present invention relates to a remote access technology, more specifically, to a system based on the Remoting software architecture for shared access of power grid encryption machines, and a method for updating smart meter parameters based on the system for shared access of power grid encryption machines based on the Remoting software architecture. Background technique [0002] The existing smart meter remote centralized reading system is a single meter reading system, which includes an application system server, multiple concentrators connected to the server, and multiple collectors connected to the concentrators. There is an electric meter. The collector transmits the data collected by the electric meter to the concentrator, and then the concentrator transmits the information to the application server, thus completing the function of the remote centralized copying system. [0003] However, the low-frequency narrowband communication is used betwe...
