Abstract

The utility model discloses a kind of GOOSE based on FPGA, mobile agent server protocol resolver, it is characterised in that including FPGA and ARM, the FPGA is connected with ARM by AXI buses；FPGA includes ethernet mac module, GOOSE filtering modules, GOOSE processing modules, BLVDS bus modules and ethernet frame uploading module, the ethernet mac module, GOOSE filtering modules and ethernet frame uploading module are linked in sequence successively, and the GOOSE filtering modules, GOOSE processing modules and BLVDS bus modules are sequentially connected successively.The utility model carries out the transmitting-receiving of ethernet data frame, and real-time is high, and scalability is strong, because GOOSE message requires that the real-time of data processing is high, the parsing and processing work of GOOSE message is realized using FPGA, is well positioned to meet requirement of real-time.

Description

A kind of GOOSE based on FPGA, mobile agent server protocol resolver

Technical field

A kind of GOOSE based on FPGA, mobile agent server protocol resolver are the utility model is related to, belongs to Automation of Electric Systems Field.

Background technology

IEC61850 standards are the unique universal standards of power system automatic field.It by the realization of standard, Realize the engineering running standardization of intelligent substation.So that the engineering construction of intelligent substation becomes specification, unified and transparent. Whether the intelligent substation engineering which system integrator establishes can pass through SCD（System configuration）File understands whole become The structure and layout in power station, have the function that for Intelligent transformer station development irreplaceable.IEC61850 includes MMS（Manufacture Message specification）、GOOSE（Towards the transformer substation case of general object）、SMV（Sampled measurement）Deng.Wherein GOOSE message and SMV messages apply to the collection and realtime control requirement height to equipment, and they are the transmission that data are carried out based on ethernet frame And control.At present, for the work of the dissection process of GOOSE stipulations and MMS stipulations completed in CPU, due to GOOSE requirements It is high to produce real-time, is gone to handle GOOSE message merely by CPU, is extremely difficult to the requirement of real-time.At the same time, CPU should locate Reason processing MMS messages, handle GOOSE message, this will certainly greatly increase the burden of CPU operations, cause the stability of a system again Decline.At present, the scheme that double nets based on CPU parse to IEC61850 stipulations, because it should parse GOOSE message, again MMS stipulations are handled, this results in the decline of CPU processing datas real-time, and operation burden increases, situations such as causing system unstable.

Utility model content

For shortcoming present in prior art, the utility model proposes a kind of GOOSE based on FPGA, mobile agent server protocol solution Analysis apparatus, is handled GOOSE stipulations by FPGA in real time, arm processor processing MMS messages, so as to improve the real-time of system and can By property.

Technical solutions of the utility model are as follows：

A kind of GOOSE based on FPGA, mobile agent server protocol resolver, including FPGA and ARM, FPGA and ARM it is total by AXI Line connects；

FPGA includes ethernet mac module, GOOSE filtering modules, GOOSE processing modules, BLVDS bus modules and ether Net frame uploading module, ethernet mac module, GOOSE filtering modules and ethernet frame uploading module are linked in sequence successively, GOOSE Filtering module, GOOSE processing modules and BLVDS bus modules are sequentially connected successively.

Ethernet mac module includes internal receipt fifo module, for receiving and sending the data frame from Ethernet.

BLVDS bus modules connect BLVDS buses.

GOOSE filtering modules are used for the data link layer filtration of ethernet data frame：It is used for GOOSE message frame Choose, and ethernet data frame is reached into GOOSE processing modules；

GOOSE processing modules, BLVD bus moulds are reached for the dissection process of message, and by the data after dissection process Block.

BLVDS bus modules, pass through BLVDS buses and substation for receiving the data of GOOSE processing modules, and by data Communication；

ARM kernels are LINUX operating systems, and ARM receives ethernet frame, real time parsing processing MMS by AXI buses ARM Stipulations.

The beneficial effects of the utility model：The utility model discloses a kind of GOOSE based on FPGA, mobile agent server protocol parsing dress Put, FPGA realizes ethernet mac module, FPGA include ethernet mac module, GOOSE filtering modules, GOOSE processing modules, BLVDS bus modules and ethernet frame uploading module, the transmitting-receiving of ethernet data frame is carried out, real-time is high, and scalability is strong；By Require that the real-time of data processing is high in GOOSE message, the parsing and processing work of GOOSE message are realized based on FPGA, can be very Good meets requirement of real-time；GOOSE filtering modules realize the filtering of GOOSE message, and ethernet frame uploading module will only receive To MMS stipulations ARM is uploaded to by AXI buses, by ARM complete MMS messages parsing work.

Brief description of the drawings

Fig. 1 is a kind of GOOSE based on FPGA of the utility model, mobile agent server protocol resolver structural representation；

Fig. 2 is the utility model and substation connection diagram.

Embodiment

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of GOOSE based on FPGA, mobile agent server protocol resolver, including FPGA and ARM, FPGA and ARM is connected by AXI buses.

FIFO（First Input First Output）：That is fifo queue.Me can be carried after supermarket shopping Full shopping cart come cashier and come the last of checkout line, the client that look at helplessly above leaves one by one. Here it is a kind of first in first out mechanism, the client being first lined up in advance leave by checkout.

BLVDS bus modules connect BLVDS buses.

GOOSE filtering modules are used for the data link layer filtration of ethernet data frame, and GOOSE message frame is selected Come, and ethernet data frame is reached into GOOSE processing modules.

GOOSE processing modules, BLVD bus modules are reached for the dissection process of GOOSE message, and by processing data.

BLVDS bus modules, pass through BLVDS buses and substation for receiving the data of GOOSE processing modules, and by data Communication, as shown in Figure 2.

ARM kernels are LINUX operating systems, and ethernet frame, real time parsing processing MMS rule are received by AXI buses ARM About.

Utility model works process is as follows, ethernet mac module, receives and send the data frame from Ethernet；When When receiving data frame, Ethernet data is stored in internal receipt fifo module by ethernet mac module, GOOSE filterings and place Manage reading and processing that module carries out data;When there is data frame to need to send, ethernet mac module sends inside by reading The data in fifo module are received, data are sent to external ethernet；The first of GOOSE filtering modules filtering ethernet data frame Layer（Data link layer）；GOOSE filtering modules are used to judge whether the type field value of data frame to be GOOSE message lattice Formula, if GOOSE message, data frame will be uploaded to GOOSE processing modules, GOOSE message will be carried out by GOOSE processing modules Dissection process；Otherwise data are uploaded to ethernet frame uploading module；Ethernet frame uploading module is by GOOSE filtration treatments After modular filtration falls GOOSE message, remaining ethernet frame is uploaded in ARM, ethernet frame uploading module by ethernet frame with The form of AXI buses is uploaded in ARM.

It the above is only preferred embodiment of the present utility model, it should be pointed out that：For the ordinary skill people of the art For member, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications Also it should be regarded as the scope of protection of the utility model.
