Problems solved by technology
The applicability of this solution has limitations. When there are many interfaces in the network, a huge channel system will be established, which is not easy to maintain and manage, and the information exchange mode between interfaces is cumbersome.
Not only that, but the configurability of this method is very poor. When changing the application scenario, the channel needs to be re-established

Embodiment Construction
[0032] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0033] A heterogeneous network contains a variety of communication devices and communication media. When information is forwarded between these devices, it is necessary to implement this multi-interface information forwarding mechanism. The invention proposes a method for information interaction of various interfaces in a heterogeneous network. figure 2 It is an example of a heterogeneous network with multiple devices, including four interfaces: USB, RS232, PHY (Ethernet port), and Pmod. Among them, Pmod is a custom transmission protocol interface expanded by users. These interfaces are used to connect various devices to obtain ground, air and atmospheric monitoring parameters. In the system, RF (Radio Frequency) is used to realize data communication between devices, and the RS232 interface is used to connect with the devices. image ...

The invention provides a method for information interaction of various interfaces in the heterogeneous network. The method includes analyzing an interface layout structure of the heterogeneous network, counting interface information in the network, allocating a virtual IP (internet protocol) address and an interface index value to each interface in the network, and setting up communication among the interfaces through an IP lookup and addressing mode; judging working states of the interfaces through the interface index values; generating trigger signals for data frame format conversion among the interfaces through a double-index value lookup table. The method is applicable to data exchange among different interfaces in various heterogeneous networks, and has high transportability.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for information interaction of various interfaces in a heterogeneous network. Background technique [0002] With the implementation of the low-altitude open policy, the application field of civil helicopters has been further expanded, mainly reflected in: the continuous expansion of application fields, the formation of a networked service pattern, and unmanned helicopters. Especially in many social public welfare fields, such as urban environmental monitoring / protection, natural disaster forecast / prevention, etc., civilian unmanned helicopters will be more widely used. However, when UAVs perform tasks, due to factors such as their own physical performance constraints and limited battery power, it cannot complete the monitoring of all target areas at one time, and the task requirements for UAV monitoring in different monitoring areas are also different. ...
