In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Referring to fig. 1 to 3, the communication terminal architecture design technology based on audio relay provided by the present invention includes a relay module and a communication terminal module, where the relay module includes a relay channel module and a relay forwarding module, the relay channel module includes a source node S, a relay node R, and a destination node D, and the relay cooperative transmission is completed through two stages, where the two stages specifically include the following steps: the first stage is as follows: the source node S transmits signals in a broadcast manner, and both the relay node R and the destination node D receive signals, i.e., S → (R, D), which is generally referred to as a broadcast phase. And a second stage: the phase in which the source node S and the relay node R transmit signals and the destination node D receives signals, i.e., (S, R) → D, is referred to as a relay forwarding phase. The relay forwarding module is provided with two relay processing modes of decoding forwarding and amplifying forwarding according to different processing modes of the relay node for the received source node signal. Decoding and forwarding: the basic content is that after the first stage relay node receives the signal sent by the source node, the signal must be decoded first, then re-encoded and forwarded to the destination node. It can be seen that decode-and-forward is essentially a digital signal processing approach. Amplifying and forwarding: the basic content is that after receiving the signal sent by the source node in the first stage, the relay node does not demodulate the signal, but simply amplifies the signal and directly forwards the signal to the destination node. The amplification forwarding is essentially an analog signal processing method. The characteristics of wide propagation range and high speed of the relay technology can adapt to the dynamic topological characteristic of the wireless network, so that the wireless network has good expansibility. The relay technology is introduced into the individual backpack communication wireless network to form a new individual backpack communication self-adaptive wireless communication network, so that the communication quality and the propagation range are further improved, and the safety of individual backpack communication is further facilitated. The communication terminal is composed of an ARM main controller, a sensor module, a GPS module, a wireless module, a display module, a voice module and a power module. The communication terminal includes the steps of: the method comprises the following steps that (1) road condition information and individual backpack communication self performance information are obtained by a sensor module and are transmitted to an ARM main controller module through a CAN bus; (2) the ARM main controller analyzes and processes the information and classifies the priority of the information; meanwhile, a temporary mobile self-organizing network is established through the wireless module and the surrounding individual soldier backpack communication, and information is broadcasted to the surrounding individual soldier backpack communication; and (3) the individual backpack communication can also receive the information of the surrounding individual backpack communication, and the information is processed correspondingly after the data of the ARM main controller is analyzed and fused, and is continuously broadcast and sent. The ARM main controller selects STM32-F407 which is provided with an FPU and a DSP instruction set, is provided with two AD with 12 bit conversion rate of 2.4MHz and two DA with 12 bits, is provided with an ARM main controller and is provided with an ARM main controller, wherein the STM32-F407 is provided with Contex-M4 as a core, is provided with main frequency 168MHz, is provided with two 12 bit AD with 2.4MHz conversion rate and two DA with 12 bits, is integrated with a Flash with 512KB and an SRAM with 192KB on a chip, and an encryption processor (CRYP) is provided with two CAN controllers, a high-quality digital audio interface IIS and rich IO interfaces, so that the content required by the design of a single-soldier backpack communication terminal CAN be better met. The operating system of the communication terminal adopts a micro C/OS-II real-time operating system. The uC/OS-II is a preemptive real-time multitask operating system based on priority, has small kernel, strong real-time performance and high portability, and is particularly suitable for task management in the mobile communication process. The communication terminal is cooperated with a communication system to mainly research wireless networking and communication of vehicles under an ARM main controller. The software operation flow chart of the system is shown in figure 3. After the backpack communication of the individual soldier is started, each module is initialized, a mu C/OS-II operating system is loaded, and the networking beacon is detected after the system is activated. If the networking beacon exists, accessing a self-organizing network of the surrounding individual soldier backpack communication, and receiving the information in the network; and if no networking beacon exists, the sensor module collects information. The main controller performs fusion processing on the information and performs information classification, and if the information is an emergency message, the information is immediately forwarded and is broadcasted in a voice mode; if the message is a secondary message, the screen displays and forwards the message. The message forwarding process is that the individual backpack communication is rapidly broadcasted in the ad hoc network, so that the message transmission range is enlarged. The above are merely examples of the present invention, and common general knowledge of known specific structures and characteristics in the schemes is not described herein. It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
