An existing multi-system complete machine includes multiple systems, for example, an intelligent whiteboard used in a classroom includes at least a PC system and a host system, and an intelligent conference tablet includes at least an android module and a host system, or may be provided with other system modules as needed. The multi-system complete machine is equivalent to integrating a plurality of single system terminals together, and when each system module is connected with an external network, data transmission is carried out through a network interface of each system module. However, the more system modules are, the more network interfaces are arranged on the complete machine of the multi-system, and many disadvantages occur, for example, for a WIFI network interface, the interference among a plurality of WIFI network signals is very large, and the number of exposed antennas is large, which is not beneficial to each system to connect with a network, and the number of hardware is large; for the wired network interfaces, the number of exposed wired network interfaces is large, which is not beneficial to the selection of users, and the hardware setting is large.

The subsystem does not need to be directly connected with an external network, so that the subsystem only reserves one internal network interface for connecting the switch, is connected with the local network through the switch and disables the other network interfaces. The multi-system network interconnection equipment can be connected with more subsystems without increasing network interfaces, so that the hardware design is simplified, and the cost is saved.
On the basis of the above embodiment, the multisystem network interconnection device further includes: mass storage hardware connected to the local area network; the host system is further configured to: and starting the inter-system data sharing function to realize that at least one subsystem shares the data stored in the mass storage hardware through the local area network.

Example two
Fig. 2 is a flowchart of a multi-system network interconnection method according to a second embodiment of the present invention. The method of the embodiment may be performed by a multi-system internetworking device, which may be implemented by software and/or hardware, and may be generally integrated in a multi-system internetworking device. As shown in fig. 2, the method for interconnecting multiple systems in this embodiment specifically includes:
s210, local area network configuration is carried out, so that at least one subsystem is accessed into the local area network through a switch.
Before a subsystem of the multi-system network interconnection equipment is connected with an external network, a main system of a multi-system complete machine is firstly subjected to local area network configuration to share a private local area network for external network resources accessed to the multi-system complete machine, so that the subsystem is accessed to the local area network through a switch to obtain the external network resources or transmit data to the external network.

The whole multi-system complete machine can complete the connection of all subsystems and an external network only by one network interface, reduces the arrangement of exposed antennas and exposed wired interfaces, simplifies the hardware design, and avoids the problem of large interference among WIFI signals caused by a plurality of WIFI interfaces.
In addition, sharing a local area network by multiple subsystems can provide convenience to users when networking is needed. For example, in a wireless network environment using internet authentication, a multi-system network interconnection device is used, and in a conventional design scheme, independent authentication needs to be performed in a main system and each subsystem, and specifically, when a user connects to a WIFI network, the user needs to input a password for multiple times to perform authentication of each system. In the scheme of the embodiment, the authentication is only needed once in the whole system, all the subsystems can share the authentication, and data transmission is carried out through the local area network and the external network, so that the multi-system whole machine can be connected with the network more quickly.

EXAMPLE III

In this embodiment, a process of local area network configuration is described specifically on the basis of the second embodiment, and specifically, the method for interconnecting multiple system networks includes:
s310, initializing the configuration of the domain name system and the dynamic host configuration protocol.
A Domain Name System (DNS) is a distributed database on the Internet as a mapping between Domain names and Internet Protocol (IP) addresses, and enables users to access the Internet more conveniently without having to remember IP strings that can be read directly by a machine. That is, each IP address may have a hostname consisting of one or more strings separated by decimal points. With the host name, the IP address of each IP device is not required to be remembered, and only the host name which is relatively intuitive and meaningful is required to be remembered.
The Dynamic Host Configuration Protocol (DHCP) is a network Protocol of a local area network, and works by using a User Datagram Protocol (UDP), and has two main purposes: an IP address is automatically assigned to an internal network or network service provider as a means of central management of all computers to a user or internal network administrator. In this embodiment, the DHCP may allocate an IP address to each subsystem to complete the configuration of the lan.

In this embodiment, the switch is further connected to a network interface, and the switch accesses a gateway of the local area network through the network interface and acquires an IP address allocated to the subsystem by using a DHCP, so that the subsystem acquires the IP address and establishes a network connection with the local area network.
S340, configuring an IP information packet filtering system iptables to realize the functions of network forwarding and firewall.
The iptable is used for configuring network forwarding, so that forwarding of network packets between subsystems can be achieved, and network packets sent out by the subsystems can be forwarded to an exit network (a WIFI network or a wired network), so that the subsystems can communicate with the external Internet. Meanwhile, the iptable has a firewall function and shields the uncontrolled access of an external network to the subsystem network. In the multi-system network sharing method in the embodiment, the internal local area network sharing is used, and the iptable shields the interference of an external network to the whole network, so that the safety is improved.
S350, receiving external network data through the network interface, and sending the external network data to the switch so that the switch forwards the external network data to a corresponding subsystem; or receiving internal data sent by a subsystem through the switch, and sending the internal data to an external network through the network interface.
Illustratively, if an android subsystem in the multi-system network interconnection device exchanges data of WeChat voice information with an external network, a voice data packet of the external network is received through a network interface of a main system, and is sent to a switch through a local area network, and the switch forwards the voice data packet to the android subsystem; or the local area network can receive the internal voice data packet sent by the android subsystem through the switch and send the internal voice data packet to the external network through the network interface of the main system.
