Example:

Referring to Fig. 1-2, the present invention provides a technical solution: a data security transmission platform with double buffering based on ad hoc network technology, including:

A node, the node being a medical device integrated with a host module and a routing module;

Wherein, the host module is loaded with application programs, such as editors, browsers, etc., the routing module runs the routing protocol, and the routing protocol is reset to form a privatized routing protocol, and completes the forwarding of data packets according to routing policies and routing tables And routing maintenance work, so the node is required to implement a suitable routing protocol. ;

The host modules of the nodes establish data transmission connections through routing modules, and the routing modules of each node meet the reset routing protocol. The current network frequency bands of operators are as follows: 1. 2G network: GSM, EDGE; 2. 3G network: WCDMA, CDMA, TD-SCDAM; 3, 4G network: TD-LTE, FDD-LTE. The division of TD-LTE frequency bands is specifically that China Mobile has obtained 130MHz in total, which are 1880-1900MHz, 2320-2370MHz, and 2575-2635MHz; China Unicom has obtained 40MHz, which are respectively 2300-2320MHz and 2555-2575MHz; -2390MHz, 2635-2655MHz. Within the range of the above-mentioned authorized frequency bands, the routing modules select a frequency band that is different from other mobile phones to build a trusted wireless communication channel.

In the mobile ad-hoc network, due to the random movement of nodes (medical equipment), the power-on and power-off of nodes at any time, the change of transmission power of wireless signaling devices, the mutual interference between wireless channels, and terrain, the mobile terminal The network topology formed through wireless channels may change at any time, and the change method and speed are unpredictable.

The mobile ad hoc network has no strict control center, and the status of all nodes is equal, which is a peer-to-peer network. Nodes can join and leave the network at any time, and the failure of any node will not affect the operation of the entire network, which is highly invulnerable.

The central control terminal establishes a connection with each node, the central control terminal controls the on-off of the wireless communication channel between the nodes, dynamically adjusts the signal coverage of the nodes, and the central control terminal and the nodes form a data security transmission platform.

The way for the central control terminal to remove nodes from the data security transmission platform from the data security transmission platform is as follows:

When the node is turned on, the central control terminal opens the browser (the central control terminal also serves as a node), enters the URL 192.168.1.1 and enters;

Enter the background page of the routing module, enter the password to log in the background and click Login to enter the background of the routing module;

After entering the background, based on the module-based disabling column, click the node that is required to prohibit access to the data security transmission platform to prohibit the device from being connected to the Internet.

If you want to add a new node (medical device), you can add a new device in the settings by binding IP and MAC on the page. Click Add to enter the node name and IP address of the routing module, and click Save to bind the new device.

Preferably, the application program loaded in the host module includes a data editor, a data browser, a data identification unit and a data conversion unit.

Preferably, the data transmission path between the nodes is that the host module of one node transmits data through the routing module to the routing module of another node through a wireless communication channel and outputs the data to the host module of another node.

Preferably, within the authorized frequency range, the routing modules select a frequency band different from that of the mobile smart device to establish a wireless communication channel.

Preferably, the routing module between the nodes establishes a wireless communication channel in a specific manner as follows:

The routing module of the node to be added to the data security transmission platform sends a connection establishment request to the node in the data security transmission platform and adjusts the routing protocol of the routing module to a privatized routing protocol;

The nodes in the data security transmission platform use the IP address of their own routing module and the IP address of the routing module of the node to be added to the data security transmission platform as the communication transmission address and form a wireless communication channel.

Preferably, the specific way of resetting the routing protocol is:

The routing protocol adopts a static routing protocol; static routing is suitable for small-scale and infrequently changing networks, and dynamic routing is suitable for large networks. In this way, the change of the path does not require the network manager to manually change the routing information, and the router will automatically adapt to it. Changes in network topology;

By configuring static routing, users can artificially specify the path to be passed when accessing a certain network, so that the data transmission between nodes is transmitted according to the set path.

The nodes set the data transmission path between the host modules by themselves, and the data between nodes is transmitted through the set path.
