Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of hand-held network data isolator of intelligent substation, comprising: light network interface interface, FPGA signal processing module, cpu data processing module, memory module, configuration network interface.
Light network interface interface is mainly used in the SV message, GOOSE message, the IEEE1588 message that receive and send transformer station process layer network.
Light network interface interface, at least comprises the first smooth network interface interface of the SV message for receiving transformer station process layer network, GOOSE message, IEEE1588 message; For receiving the second smooth network interface interface of the SV message of relay-protection tester, GOOSE message, IEEE1588 message; And for send the transformer station process layer network after restructuring SV message, GOOSE message, IEEE1588 message the 3rd smooth network interface interface.The SV message of transformer station process layer network, GOOSE message, IEEE1588 message comprise the IEEE1588 message of the SV message of merge cells MU, the GOOSE message of intelligent terminal and time synchronism apparatus.First smooth network interface interface, the second smooth network interface interface, the 3rd smooth network interface interface can be all multiple.
FPGA signal processing module major function comprises: receive configuration-direct by configuration network interface, and according to configuration-direct to the SV message from the first smooth network interface interface, GOOSE message, the SV message of IEEE1588 message and the second smooth network interface interface, GOOSE message, IEEE1588 message carries out isolation restructuring encapsulation, isolation restructuring encapsulation namely according to configuration-direct by corresponding first smooth network interface interface to a kind of message or multiple message replace with the message of corresponding types in the second smooth network interface interface, then the message after restructuring isolation is sent by the 3rd smooth network interface interface.Packet reassembling isolation in the utility model only relates to selection and the restructuring transmission of message, does not carry out data operation to message data, does not relate to the improvement of method.
The major function of cpu data processing module comprises: receive configuration-direct from configuration network interface and send to FPGA signal processing module.
The major function of memory module is for cpu data processing module provides memory space.
Configuration network interface comprises the electric Ethernet interface that is supported 10/100/1000M, for receiving configuration-direct.
