fig. 3 is a flowchart of the virtual cable method according to the present invention executed by using a serial port line.
[ detailed description ] embodiments
Referring to fig. 1, the virtual cable scheme of the present invention includes three main contents: the cloud platform forwarding server, the remote gateway and the local gateway.
The method comprises the following steps: firstly, whether a gateway needing to establish a virtual cable is on-line or not is confirmed, and if the gateway is not on-line, the problem of gateway disconnection is checked. The method comprises the steps of selecting a virtual cable mode of a gateway, wherein the current scheme comprises two virtual cable modes of a network cable and a serial port cable. After parameters needed by the server are forwarded through the platform, a correct virtual cable working mode for starting the field gateway and the local gateway is set. If the platform forwarding server prompts successfully, the gateway works in a virtual cable mode immediately.
Referring to fig. 2, the gateway portal virtual cable data forwarding process:
the data sources of IP packets are four: local area network, local gateway IP protocol stack, remote gateway local area network, remote gateway IP protocol stack. Since there are a large number of IP packets, ARP packets, or other network protocol packets in the local area network at each time. Therefore, a virtual routing software is designed to run in the gateway, and when the network port virtual cable is set, the platform forwarding server will issue the remote and local IP addresses to be communicated to the respective gateways. That is, the local gateway has the host IP group address of the remote lan, and the remote gateway has the IP group address of the local lan.
After the whole system is started, when a data packet which accords with the gateway IP group address exists in the local area network, the data packet is sent to the platform forwarding server through the 4G. The platform forwarding server sends the message to the opposite-end gateway, and the virtual routing program of the opposite-end gateway replaces the source MAC of the packet with the MAC address of the virtual routing program, so that the target device can return the data packet correctly after receiving the data packet. When the data packet is returned correctly, the data enters the gateway network port of the opposite terminal to input data, and the forwarding IP group which is in accordance with the virtual route record of the gateway is forwarded to the local gateway. The local gateway replaces the source MAC address of the data packet with the MAC address of the local gateway, and sends the data packet to the local area network to complete the data forwarding process.
When there is an IP group address packet corresponding to the remote gateway record in the remote lan, the processing flow is similar to the above described flow. Specifically, when there is a data packet conforming to the gateway IP group address in the remote lan, the data packet is sent to the platform forwarding server through the 4G. The platform forwarding server sends the message to the opposite-end gateway, and the virtual routing program of the opposite-end gateway replaces the source MAC of the packet with the MAC address of the virtual routing program, so that the target device can return the data packet correctly after receiving the data packet. When the data packet is returned correctly, the data enters the gateway port of the opposite terminal to input data, and the forwarding IP group which is in accordance with the virtual route record of the gateway is forwarded to the remote gateway. The remote gateway replaces the source MAC address of the data packet with the MAC address of the remote gateway, and sends the source MAC address to the remote local area network to complete the data forwarding process.
Referring to fig. 3, the gateway RS485 serial port virtual cable forwards data:
the Hex data comes from only two sources: a serial port network accessed by a local gateway and a serial port network accessed by a remote gateway. Since the gateway itself does not need to process any message, it is only necessary to directly forward the respective received messages. And the software of a virtual route runs in the background, and the Hex data input by the serial port of the gateway is monitored at any time. And if the data is received, the data is sent to the platform forwarding server through the 4G network and then forwarded to the opposite-end gateway. After receiving the data, the gateway directly sends the data to the hardware serial port of the gateway without processing. Therefore, data forwarding of the RS485 based virtual cable is realized.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
