Existing protocol conversion technologies usually perform mapping based on a fixed target protocol, lacking flexibility and adaptability, and unable to dynamically adjust the protocol type according to the network environment. Summary of the Invention

[0003] To solve the problems of the existing technology, an adaptive protocol conversion gateway system and control method for heterogeneous network engineering are provided, aiming at how to design a system that can intelligently switch between different protocols and optimize communication efficiency.

[0005] Further, the protocol conversion module includes a mapping table and a data parser. The data parser is used to parse data structures, addresses, and data contents; the mapping table is used to map and reorganize the parsed data according to the requirements of the target protocol.

Its expression is: , Wherein, is the selected protocol; is the set of available protocols; An adaptability function representing the protocol is calculated based on the protocol type P, data flow type S, and network state N, where f(P, S, N) = α * compatibility(P) + β * suitability(S) + γ * network_efficiency(N). Here, α, β, and γ represent the weights of the protocol type P, data flow type S, and network state N respectively, and satisfy α + β + γ = 1; compatibility(P) represents the degree of support of the protocol for functional requirements; suitability(S) represents the matching degree of the protocol to the characteristics of the current data flow; network_efficiency(N) represents the performance of the protocol under the current network.

[0007] Furthermore, the dynamic adjustment of the protocol's transmission method according to the current network state in the network resource optimization module is specifically as follows: Obtain the maximum network throughput and the ideal delay of the protocol, calculate the adjusted throughput through the throughput adjustment formula based on the current network delay, and optimize the protocol's transmission method with the adjusted throughput.

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] In this embodiment, referring to Figure 1 , it aims to implement an adaptive protocol conversion gateway system for heterogeneous network engineering. The composition of this gateway system is as follows: Protocol Identification Module: By real-time monitoring of data streams, it automatically identifies the protocol identifier and obtains the protocol type used in the current communication. This module can analyze the protocol header information to determine the protocols used by both communication parties.

[0014] Adaptive Protocol Selection Module: According to the current network conditions (such as bandwidth, latency, packet loss rate, etc.) and the type of data stream (such as real-time requirements, data volume, etc.), it calculates the real-time fitness of each protocol type and selects the protocol with the maximum fitness value for data transmission. The module contains multiple protocol models (such as TCP / IP, UDP, MQTT, CoAP, etc.) and can dynamically select the protocol type based on the algorithm.

[0015] Protocol Conversion Module: It is used for protocol conversion and supports operations such as data format conversion between different protocols and mapping of header information to ensure that data can be accurately transmitted between different protocols.

[0016] Network Resource Optimization Module: This module dynamically adjusts the transmission method of the protocol according to the current network status. For example, when the network latency is high, it selects a protocol that supports low latency; when the bandwidth is sufficient, it selects a protocol that supports high throughput.

[0017] Data Caching and Traffic Scheduling Module: When switching between different protocols, this module is responsible for caching and traffic scheduling to avoid data loss and congestion and ensure smooth data transmission.

[0018] As Figure 2 shown, the steps for implementing adaptive protocol conversion control for heterogeneous network engineering through the system are as follows: Protocol Identification: Monitor the data stream through the protocol identification module to identify the protocol type used in the current communication; Protocol Selection: The adaptive protocol selection module selects the most suitable protocol based on the real-time network status and data stream type; Protocol Conversion: When the current communication protocol is inconsistent with the protocol selected by the adaptive protocol selection module, the protocol conversion module converts the data format according to the protocol selected by the adaptive protocol selection module; Optimized Transmission: The network resource optimization module adjusts the protocol transmission strategy according to the actual situation of the network to ensure the efficiency and stability of data transmission; Traffic Scheduling: When switching protocols, schedule caching and traffic through the data caching and traffic scheduling module to ensure smooth data transmission.

[0019] Among them, the expression of the adaptive protocol selection algorithm is: , where is the selected protocol; is the set of available protocols; represents the adaptability function of the protocol, which is calculated based on the protocol type P, data stream type S, and network status N, f(P,S,N)=a*compatibility(P)+β*suitability(S)+γ*network_efficiency(N), where α, β, and γ represent the weights of the protocol type P, data stream type S, and network status N respectively, and satisfy α+β+γ=1, * represents multiplication, compatibility(P) represents the degree of support of the protocol for functional requirements (for example, MQTT supports QoS, but UDP does not); suitability(S): The degree of match between the protocol and the characteristics of the current data stream (such as AMQP is suitable for reliable transmission); network_efficiency(N): The performance of the protocol in the current network (such as UDP performs poorly in a high packet loss network); The weights α, β, and γ can be customized according to the scenario. For example, in the power scenario, P and N may be more emphasized.

[0020] Through the protocol conversion module, the present invention uses a mapping table and a data parser to convert the data formats of different protocols to achieve cross - protocol data transmission. The process of protocol conversion can be expressed as: , wherein, represents the data after conversion; represents the data before conversion; T(·) represents the data conversion function of the protocol, which processes the differences in data formats between different protocols.

[0021] Network resource optimization strategy: During the data transmission process, the network resource optimization module ensures the efficiency of data transmission through the following algorithm, and the expression is: , wherein, represents the throughput adjusted according to the current network state; represents the maximum throughput is the adjustment coefficient; and represent the current network latency and the ideal latency value respectively. The adjusted throughput is equal to the maximum throughput divided by 1 + α multiplied by the difference between the current latency and the ideal latency. If the current latency is equal to the ideal latency, the denominator is 1, and the adjusted throughput is the maximum throughput. If the current latency is greater than the ideal latency, the denominator will be greater than 1, and the adjusted throughput will be less than the maximum throughput. If the current latency is less than the ideal latency, the denominator will be less than 1, and the adjusted throughput will be greater than the maximum throughput, which is possible in some cases, such as when the network performance is better than expected. This formula dynamically adjusts the throughput, optimizes network resources, and ensures the efficiency of data transmission by considering the difference between the current latency and the ideal latency and using the adjustment coefficient α to balance this difference.

[0022] In this embodiment, the adjustment coefficient Setting principle: In the dynamic scheduling of network resources, is the key factor affecting the trade - off between latency and throughput.

[0023] The more the current network latency deviates from the ideal latency, the more obvious the throughput adjustment is.

[0024] Controls the sensitivity of this adjustment (amplifies or moderates this adjustment process).

[0025] The larger → more sensitive to latency changes (the throughput drops faster).

[0026] The smaller → the adjustment is smoother (the system is more stable).

[0027] In smart grids and Internet of Things platforms, multi - protocol communication needs to be processed while maintaining high efficiency and real - time performance. The setting follows the following principles: 1. Stability first: In the smart grid scenario, data collection needs to run stably for a long time, and the protocol cannot be frequently switched or the bandwidth cannot be significantly adjusted. It should not be too large.

[0028] 2. Business - type driven: When the real - time requirement is high (such as alarm uploading and load control), should be relatively large, and reducing latency is prioritized; while in periodic data collection (such as meter reading), can be set lower.

[0029] 3. Network - status feedback adjustment: The system supports dynamic adjustment (adaptive ): Adjust the value according to the network historical status feedback. For example, if the network latency is high but stable for a long time, then can be appropriately lowered to reduce unnecessary bandwidth reduction.

[0030] The setting of should balance real - time performance, stability and network feedback: The range of conventional setting parameters is as follows: Real - time control / alarm: 0.7 - 0.9; Periodic collection: 0.4 - 0.6;
