Brief description of the drawings
Fig. 1 is structured flowchart of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
A kind of protocol conversion device of the Multi-netmouth multi -CPU based on exchange chip, including exchange chip, the N1 of exchange chip
The individual external N1 network of network interface, one network interface of each network connection, N2 network interface connection N2 CPU, each CPU of exchange chip
One network interface of connection, at least one CPU is configured to exchange chip, and a general CPU is carried out by SMI mouthfuls to exchange chip
Configuration, configures by exchange chip, and N1 network interface of external network carries out data friendship with N2 network interface for being connected CPU
Mutually, data interaction is not carried out between N1 network interface of external network, data interaction is not carried out between N2 network interface for connecting CPU,
Wherein, N1 and N2 are not less than 2.
Type of message and installation cost for being included according to existing power system, IEC61850 stipulations etc., such as Fig. 1 institutes
Show, N1 and N2 are equal to external 2 networks of 2 network interfaces of 2, i.e. exchange chip, each network connection one in above-mentioned conversion equipment
Individual network interface, 2 network interface connections 2 CPU, each CPU of exchange chip connect a network interface.This 2 CPU are respectively defined as protection
CPU and communication cpu, communication cpu are configured by SMI mouthfuls to exchange chip, after exchange chip is configured, the 2 of external network
Individual network interface carries out data interaction with 2 network interfaces for being connected CPU, and data interaction is not carried out between 2 network interfaces of external network, connection
Data interaction is not carried out between 2 network interfaces of CPU, protection CPU receives GOOSE the and SMV messages that simultaneously processing and exchanging chip sends,
Communication cpu receives and processing and exchanging chip sends MMS messages.
Above-mentioned two CPU can be using the ARM3352 processors of TI companies；Above-mentioned exchange chip can use Marvell companies
MV88E6060 exchange chips, the exchange chip has 6 network interfaces (Fast Ethernet), fully meets connection 2 networks and 2
The requirement of individual CPU, each network interface respectively has a Port Based VLAN register, because 2 network interfaces of external network are (in figure
P0 and P1) data that receive will be forwarded to 2 network interfaces (P2 and P3 in figure) of connection CPU, communication cpu is each to P0 and P1
From low 11 of Port Based VLAN registers be set to 0xC (b00000001100)；P2 and P3 can only be by data forwarding
To P0 and P1, therefore it is (b00000000011) to set low 11 of the Port Based VLAN of P2 and P3；It is complete by the setting
The VLAN based on network interface is divided in pairs, it is ensured that the routing direction of data, as shown in Fig. 1 four-headed arrows.Meanwhile, in order to incite somebody to action
GOOSE message, SMV messages and MMS messages it is corresponding be sent to protection CPU and communication cpu, communication cpu need according to table one to
Table five, is configured to exchange chip；First, the MAC Address for setting P2 and P3 is set in corresponding ATU, so can mistake
The data for not being destined to the equipment in network are filtered, GOOSE message, the destination address of SMV messages are probably broadcast address, because
Be added in ATU for respective broadcast address by this, by the operation to ATU registers, effectively can report GOOSE message, SMV
Text and MMS messages are distributed to P2 and P3, while the data that CPU side will send are interacted by P0 mouthfuls and P1 mouthfuls with outside, pass through
Above-mentioned setting is realized, GOOSE the and SMV messages that protection CPU receives and processing and exchanging chip sends, communication cpu receives and locates
Reason exchange chip sends MMS messages.
