It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0022] Before presenting the embodiments, the following terms are explained first.
[0023] Energy consumption ratio: Energy consumption ratio usually refers to the ratio between energy consumption and output or performance, which is used to measure energy utilization efficiency.
[0024] The present invention provides a communication method and system for a highway warning terminal, which are described below.
[0025] Figure 1 A flow chart of an embodiment of the communication method of the highway warning terminal provided by the present invention is shown as follows: Figure 1 As shown, the communication method of the highway warning terminal includes: S101. Acquire real-time weather parameters and real-time communication event types of a highway warning terminal.
[0026] It should be noted that by obtaining the real-time weather parameters of the highway warning terminal, the real-time network parameters of the highway warning terminal can be determined, and thus the communication link status of the highway warning terminal can be determined. Furthermore, by obtaining the real-time communication event type of the highway warning terminal, the data transmission requirements of the highway warning terminal can be determined. Based on the communication link status and data transmission requirements of the highway warning terminal, a foundation can be provided for the subsequent determination of an appropriate communication method.
[0027] S102. Using the real-time weather parameters as input to a network parameter prediction model to obtain real-time network parameters output by the network parameter prediction model, wherein the network parameter prediction model is obtained by training an LSTM network based on historical weather parameters and historical network parameters.
[0028] It should be noted that predicting network parameters through weather parameters instead of directly measuring them can reduce the frequency of network evaluation and thus reduce the resources consumed in formulating communication strategies.
[0029] S103. Determine the communication mode of the highway warning terminal based on the real-time network parameters, the real-time communication event type, and a network parameter-energy consumption ratio table, wherein the network parameter-energy consumption ratio table is constructed based on energy consumption ratios corresponding to different types of communication events under different network parameters.
[0030] It should be noted that to balance energy efficiency and network stability, this paper introduces the concept of energy consumption ratio. A network parameter-energy consumption ratio table is constructed based on the energy consumption ratios corresponding to different types of communication events under different network parameters. This effectively reduces energy consumption ratio calculation time and computational complexity. By substituting real-time network parameters and real-time communication event types into the network parameter-energy consumption ratio table, the resulting energy consumption ratio can be used to further determine the communication method for the highway warning terminal, minimizing energy consumption while ensuring network stability.
[0031] In summary, the communication method for the highway warning terminal provided in the embodiment of the present invention first determines the communication link status and data transmission requirements of the highway warning terminal based on the real-time network parameters and real-time communication event type of the highway warning terminal, providing basic conditions for subsequently determining a reasonable communication method. Then, the real-time network parameters and real-time communication event type are substituted into the network parameter-energy consumption ratio table, and the communication method of the highway warning terminal is further determined based on the obtained energy consumption ratio. While ensuring network stability, energy consumption is reduced as much as possible. The present invention can achieve a dynamic balance between the energy efficiency and network stability of the highway warning terminal.

These events require higher network stability than ordinary communication events.

[0043] In some embodiments of the present invention, the energy consumption ratio may be calculated based on the following formula:
[0044] in, Indicates the energy consumption ratio, Indicates the proportion of protocol overhead, Indicates the total amount of data transmitted in a single time. Represents the dynamic power consumption of a single transmission, Indicates the static power consumption of a single transmission.
