[0002] Shortwave communication link building is an important prerequisite for shortwave communication. Only when the link is successfully established can message forwarding be realized. There are different link building strategies in the prior art. During the communication process of long-distance point-to-point shortwave message transmission, due to The signal strength attenuates greatly after long-distance transmission, coupled with the influence of the electromagnetic environment, the communication quality is poor, resulting in poor communication. Therefore, new requirements are put forward: for medium and long-distance short-wave communication, without relying on other communication means How to ensure the quality of communication when only short-wave communication is used

Embodiment 1
[0045] A short-wave automatic transfer method of the present invention, such as figure 1 shown, including the following steps:
[0046] S1, according to the sender and destination of message data, establish a transfer station network including a plurality of transfer stations;
[0047] S2, in the relay station network, the current relay station sends a link establishment request including the initiator, routing value and destination to other relay stations in the relay station network;
[0048] S3, the transfer station that receives the link establishment request parses out the destination from the link establishment request, if the transfer station that receives the link establishment request is the destination, then completes the link establishment with the initiator to form a communication link; otherwise , adding forwarding information to the link building request, and sending out the link building request with the added forwarding information, the forwarding information ...
Embodiment 2
[0070] The present invention also provides a device for realizing the short-wave automatic transfer method, the hardware block diagram of the device is as follows Figure 10 As shown, it includes computer platform motherboard, shortwave integrated modem, switch control unit, key control unit, front and rear panel interface unit, display driver module, serial port display module and power supply module, etc.
[0071] a) Computer motherboard: provide a general software and hardware platform for this device, through which functions such as short-wave automatic transfer function, transfer parameter setting, message sending and receiving, display and communication are completed.
[0072] b) Shortwave integrated modem: It is the core communication unit of this equipment, compatible with shortwave network dedicated communication equipment, and completes shortwave message sending and receiving.
[0073] c) Transition control unit: it is the bridge unit of the equipment, through which ...

Abstract
The invention relates to the technical field of wireless short-wave communication, in particular to a short-wave automatic message forwarding method and device. The method specifically comprises the following steps: S1, a message forwarding station network comprising a plurality of message forwarding stations is established; S2, in the message forwarding station network, the current message forwarding station sends a link establishment request comprising an initiator, a routing value and a destination to other message forwarding stations in the message forwarding station network; s3, the message forwarding station receiving the link establishment request analyzes the destination from the link establishment request, and if the message forwarding station receiving the link establishment request is the destination, link establishment with the initiator is completed, and a communication link is formed; otherwise, forwarding information is added to the link establishment request, the link establishment request with the added forwarding information is sent out, and the forwarding information comprises the information of the forwarding station and the routing weighted value of the forwarding station. By adopting the link establishing method and the link establishing device, the communication link is dynamically established in real time, the signal-to-noise ratio of the communication signal of the relay station on the long-distance communication link is ensured to be the current optimal all the time, and the communication quality is improved.
