Fig. 2 is the schematic diagram of the communication process of the arp address resolution protocol of a kind of remote network control system based on VLAN of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
The present invention relates to a kind of remote network control system based on VLAN, comprise in the same network segment one of IP address and be installed on the LUT of local user and another is installed on the remote client terminal of remote client, this remote client terminal is installed on controlled industrial control equipment, and described LUT is connected with the public network server be connected on the internet respectively by a telecommunication network connector with remote client terminal.Telecommunication network connector is with 2 Ethernet interfaces.The Ethernet interface 2 of local user's telecommunication network connector connects public network server by the Internet, and Ethernet interface 1 connects the equipment network interface of local user.The Ethernet interface 2 of the telecommunication network connector that remote client installs connects public network server by the Internet equally, and Ethernet interface 1 connects the equipment network interface of remote client.The Ethernet data bag that the equipment of local user and the equipment of remote client send is received by the telecommunication network connector be connected separately respectively, the packet received sends to public network server after adding identifying information code and pairing mark, public network server marks Packet Generation to the telecommunication network connector of corresponding pairing according to identifying information code and pairing, the Ethernet interface 1 eventually passing telecommunication network connector sends to corresponding local user or the equipment of remote client, realizes local device like this and is connected with the straight-forward network of remote equipment.
Telecommunication network connector does not need to have public network IP address, as long as can connecting Internet just energy reliably working.Public network server can serve the telecommunication network connector of multiple pairing, and the quantity of process depends on performance and the network bandwidth of server.Purposes: the remote programmable of programmable controller, remote monitoring, the remote monitoring of man-machine interface, and other need to utilize the Internet to enter the application of specific local network.
Described telecommunication network connector is by local network interface chip (network interface chip ENC28J60), internet interface chip (network interface chip W5500) and arm processor are formed, and local network interface chip is connected by SPI serial line interface with arm processor with internet interface chip.After telecommunication network connector power-up initializing, internet interface chip is set up TCP with public network server and is connected, and the telecommunication network connectors of 2 pairings are all set up TCP and are connected and just can have worked afterwards with public network server.The packet that LUT network interface sends is received by the local network interface chip of telecommunication network connector, arm processor sends to public network server by internet interface chip after identifying information code and additional counter mark being spliced with packet, public network server checks identifying information code and additional counter mark, exactly data packets is given the internet interface chip of the telecommunication network connector of pairing, telecommunication network connector sends to local network interface chip by local network interface chip after the identifying information code of packet and additional counter mark being removed, for LUT (PC) and remote client terminal (subscriber equipment), packet similarly is directly be sent to subscriber equipment from PC, except the delay of time, PC and subscriber equipment can't detect the transmission that packet have passed through the Internet.Equally, contrary path, subscriber equipment by Packet Generation to PC, can realize bidirectional data transfers.
Fig. 2 is the communication process of arp address resolution protocol, PC IP address is 192.168.1.100, subscriber equipment Ethernet interface address is 192.168.1.101, the telecommunication network connector identifying information code ID=12345-1 that PC uses, additional counter mark M=123; The telecommunication network connector identifying information code ID=12345-2 that subscriber equipment uses, additional counter mark M=123.2 the telecommunication network connectors used have identical additional counter mark, and have different identifying information code ID.
As shown in Figure 2 from PC sends ARP request, the direction of transfer of large arrow designation data bag.The Ethernet data bag comprising ARP request msg is added ID code (ID=12345-1) and the M(M=123) code of telecommunication network connector after being received by telecommunication network connector network interface, then public network server is sent to, data remain untouched and issue the telecommunication network connector (ID=12345-2) of pairing by public network server, after finally removing ID code and M, Ethernet data bag are sent to the Ethernet interface of subscriber equipment.
Subscriber equipment will automatically reply after receiving ARP request, send an ARP to telecommunication network connector (ID=12345-2) and reply packet, identical process, telecommunication network connector (ID=12345-2) by the Internet and public network server by data packets to telecommunication network connector (ID=12345-1), the ARP that last PC receives subscriber equipment replys.
In addition to the implementation, the present invention also includes other execution modes, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection range that all should fall into the claims in the present invention.
