At this time, the PLC control system of each work section does not need to have a dual network segment function, but only needs to add one three-layer switch 2 in the large network system 1, and establishes one virtual local area network 3 for each work section, that is, each work section has an individual IP network segment, and data of different work sections want to communicate, and must be forwarded through the three-layer switch 2, so that the established network is more flexible and convenient in subsequent expansion.

Each work section establishes an independent virtual local area network 3, different work sections need to realize data interaction, forwarding is realized through a three-layer switch 2, and data forwarding is realized through cooperation of a switch module 21 and a router module 22, that is, the switch module 21 judges that comparison results of a target IP address and a source IP address are different, the switch module 21 and the router module 22 are used for inter-different-VLAN communication, as shown in FIG. 3, the specific communication process is as follows:
1. and taking the equipment corresponding to the data frame received by the receiving port as active equipment, and taking the equipment corresponding to the data frame forwarded by the distributing port as target equipment.
2. The data frame carries a source IP address of the active device and a target IP address of the target device, and the switch module 21 determines, according to a comparison result between the source IP address and the target IP address, that the target device and the active device do not belong to the same virtual local area network, and sends the data frame to the default gateway.
3. The data frame is forwarded to the router module 22 through the switch module 21 and the aggregation link inside the routing module, and the first VLAN identification information of the virtual local area network 3 corresponding to the source IP address is attached to the data frame when the data frame passes through the internal aggregation link.
4. The router module 22 receives the data frame, determines a source IP address and a receiving port according to the first VLAN identification information, and the router module 22 selects a VLAN port 4 responsible for receiving and performing routing processing according to the source IP address.
5. The router module 22 selects the VLAN port 4 corresponding to the target IP address according to the virtual lan 3 corresponding to the target IP address, and forwards the data frame to the switch module 21 via the aggregation link, and when the data frame passes through the aggregation link, the second VLAN identification information of the virtual lan 3 corresponding to the target IP address is attached.
6. The switch module 21 receives the data frame and retrieves the MAC address sequence corresponding to the target IP address according to the second VLAN identification information to determine the forwarding connection port 5.
Assuming that the device a and the device C are to communicate with each other, the device a may determine that the communication object does not belong to the same network with respect to the target IP address corresponding to the device C, and therefore send data to the default gateway, the switch module 21 determines the VLAN port 4 corresponding to the connection port 5 after retrieving the MAC address sequence, and forwards the data frame to the router module 22 via the internal aggregation link, where the data frame is appended with VLAN identification information of the source IP address corresponding to the active device when passing through the internal aggregation link.
When the router module 22 receives the data frame, the source IP address and the corresponding VLAN 3 are firstly identified by the VLAN identification information attached to the data frame, and the matched VLAN port 4 is selected to be responsible for receiving and performing routing processing, because the target IP address 192.168.2.1/24 is a network directly connected to the router, and according to the VLAN corresponding to the target IP address, the VLAN port 4 is selected to forward the data frame back to the switch module 21 through the internal aggregation link, and when the data frame passes through the internal aggregation link, the VLAN identification information belonging to the VLAN corresponding to the target IP address is attached to the data frame this time.
After receiving the data frame, the switch module 21 retrieves the MAC address sequence of the virtual lan corresponding to the target IP address, and confirms that it needs to be forwarded to port 3. Since the port 3 is a normal access link, the VLAN identification information is removed twice before forwarding, and finally, the device C successfully receives the data frame forwarded by the switch.
The overall process specifically comprises the following steps: sender → switch module → router module → switch module → receiver.
The method is flexible in network expansion, is suitable for gypsum board production lines with high capacity and high speed, can solve the problem that the number of devices in an IP network segment exceeds 255, can flexibly expand the network and improve the stability of the network, and is suitable for building gypsum board production lines with high capacity, high speed and high requirements on the stability of a communication network.
