Description of drawings
Fig. 1 is a kind of structural representation that transmits switching system based on the network of one-way optical fiber channel of the present utility model.
Embodiment
As shown in Figure 1, a kind of network transmission switching system based on the one-way optical fiber channel of the present utility model, comprise Process Control Machine Case, be positioned at power supply, Intranet machine end and the outer net machine end of described Process Control Machine Case, described Intranet machine end and outer net machine end are respectively equipped with the first optical fiber network interface card and the second optical fiber network interface card, are connected by optical fiber cable between the first optical fiber network interface card of described Intranet machine end and the second optical fiber network interface card of outer net machine end; Be connected by optical fiber cable between the second optical fiber network interface card of described Intranet machine end and the first optical fiber network interface card of outer net machine end.
Described Intranet machine end and outer net machine end comprise mainboard, CPU and bus interface respectively.
The operation principle that a kind of network based on the one-way optical fiber channel of the present utility model transmits switching system is as follows:
1. outer net machine termination is received the network packet of external network, by technology such as fast protocol parsing, information safety filtrating, parallel computation processing data is unpacked fast, filters, recombinates, and is converted to the professional format packet;
2. pass through outer net machine end optical fiber network interface card A then to the unidirectional transmission packet of Intranet machine end optical fiber network interface card B;
3. packet is by optical fiber cable, and is unidirectional, do not have feedback ground and transfer to optical fiber network interface card B on the Intranet machine end from the optical fiber network interface card A on the outer net machine end, and transfers to Intranet machine end and handle;
4. Intranet machine end unpacks the professional format packet fast, encapsulates by technology such as fast protocol encapsulation and parallel computation processing, is reduced to the TCP/IP packet;
5. Intranet machine end optical fiber network interface card A mails to external network to the unidirectional transmission packet of outer net machine end optical fiber network interface card B with data then.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection range of claims of the present utility model.
