Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent pest control and agricultural informatization, and in particular to a method and system for dynamic optimization of bait palatability based on the release patterns of termite pheromones. Background Technology
[0002] With the increasing density of urban buildings and the widespread use of wooden structures, termite infestations are characterized by their high degree of concealment, wide spread, and long treatment cycles. Termite bait stations, as an important control technology, have been applied in fields such as landscaping, building construction, municipal facilities, and cultural relic protection. Current termite bait station technology mainly relies on bait attraction and pheromone guidance mechanisms. By releasing specific pheromones within the bait station, termites are guided to continuously feed on bait containing regulatory components, thereby achieving intervention and control of the termite colony. This type of technology typically focuses on pheromone ratio design, bait composition improvement, and optimized placement, and maintains the bait station's operational status through regular manual inspections and empirical adjustments.
[0003] In practice, some existing technologies incorporate sensors to collect environmental parameters and feeding behavior data within the bait station, adjusting pheromone release levels or changing bait forms based on historical data to extend the feeding cycle. However, these methods often employ fixed rules or single-timescale data analysis, failing to adequately characterize the temporal changes in termite feeding behavior and making it difficult to accurately reflect the multidimensional relationships between pheromone release status, bait status, and environmental changes. During bait station operation, when the pheromone release rhythm deviates from the actual termite feeding rhythm, it can easily lead to decreased feeding frequency, interrupted feeding paths, or colony migration, making it difficult to maintain bait palatability in the long term.
[0004] Existing technologies for bait station status modeling mostly employ simple state descriptions or static feature combinations, lacking the ability to systematically model the overall evolution of bait station operation over time. This makes it difficult to effectively predict the operational status under different combinations of pheromone release parameters and bait adjustment parameters before adjustments are made. Without refined state prediction and decision-making mechanisms, bait station adjustment behavior often lags behind actual operational changes, further exacerbating the risk of feeding interruptions and affecting the stability and continuity of termite control effectiveness.
[0005] Therefore, how to provide a dynamic optimization method and system for pheromone-driven bait palatability based on DRAMA model-based reinforcement learning combined with temporal hypergraph representation learning is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] One objective of this invention is to propose a dynamic optimization method and system for bait palatability based on termite pheromone release patterns. Addressing the problem of feeding interruptions that easily occur in existing technologies when maintaining stable bait palatability based on pheromone release patterns, this invention proposes a technical solution that constructs a temporal hypergraph using multi-source temporal data to obtain a temporal representation of the bait station's operating state. It then constructs a bait station state prediction model and decision-making mechanism based on DRAMA model-based reinforcement learning, collaboratively optimizing pheromone release control parameters and bait adjustment parameters. By introducing a closed loop of state prediction and decision feedback, this invention achieves continuous modeling, strategy generation, and dynamic updating of the bait station's operating state, effectively reducing the risk of feeding interruptions and improving the continuity, stability, and adaptability of termite bait station operation regulation.

[0132] Example 1: To verify the feasibility of this invention in practice, this example selects a continuously operating termite bait station as a practical application scenario to verify the coordinated control process of pheromone release regulation and bait state regulation during long-term operation of the termite bait station. In this scenario, the bait station needs to maintain the continuous feeding behavior of termites over a long period to ensure the stability of the pheromone induction pathway and promote continuous bait consumption, thereby meeting the actual needs of termite behavior regulation in pest control applications.
[0133] In this application scenario, existing technologies typically rely on fixed or semi-fixed pheromone release schemes, or periodically change and adjust the bait state based solely on empirical rules. In actual operation, these methods often struggle to cope with the effects of changes in termite feeding behavior over time, fluctuations in environmental parameters, and changes in pheromone diffusion states. This can easily lead to a mismatch between pheromone induction intensity and bait palatability, resulting in problems such as interrupted termite feeding behavior, decreased feeding frequency, or deviations in feeding paths. The core problem addressed in this embodiment is to introduce a technical solution based on DRAMA model-based reinforcement learning combined with temporal hypergraph representation learning to continuously model, predict, and make decisions regarding the operational state of termite bait stations, thereby maintaining dynamic coordination between pheromone release and bait state adjustment in actual operation.
[0134] In the specific implementation process, during the operation of the termite bait station, data on pheromone release status, bait status, termite feeding behavior, and environmental parameters are collected according to a fixed collection cycle. The pheromone release status data includes three dimensions: release time, release frequency, and release intensity. The bait status data includes physical and chemical state parameters of the bait. The termite feeding behavior data includes the number of feedings, feeding duration, and feeding path distribution. The environmental parameter data includes temperature, humidity, and airflow parameters. All of the above data undergoes unified time-base alignment processing to form multi-source time-series data for subsequent time-series modeling.
[0135] After obtaining multi-source time-series data, data from different sources are mapped to nodes in a time-series hypergraph. Hyperedges are constructed based on the synchronous changes between state variables under the same time index, thus forming time-series hypergraph data capable of simultaneously characterizing multi-variable relationships. Subsequently, time-series hypergraph representation learning is performed on the data. Node states are numerically normalized, and joint feature encoding is performed on the states of multiple nodes connected by hyperedges. The node states and hyperedge features are then arranged according to their time indices to obtain a node-hyperedge joint time-series feature sequence. Based on this, time-series modeling is used to obtain a time-series hypergraph state representation reflecting the evolution of node states and hyperedge relationships over time.
[0136] Building upon this foundation, a world model based on DRAMA-based reinforcement learning is introduced to further model the temporal hypergraph state representation results. Specifically, the operating states of bait stations under continuous time indices are organized into a sequence of operating states. The operating states under the current and historical time indices are used as inputs to the world model, while pheromone release parameters and bait adjustment parameters are used as state transition conditions. The evolution paths of the operating states of bait stations under different parameter combinations are simulated in the world model. By expanding multiple sets of candidate state evolution sequences, predicted state evolution sequences under multiple future time indices are obtained, and a bait station state prediction model is constructed based on these sequences.
[0137] Subsequently, a state prediction sequence is generated based on the bait station state prediction model, and a reinforcement learning decision state set is constructed. The pheromone controlled release parameters and bait adjustment parameters are defined as optional decision variables, and a corresponding parameter combination set is generated under each time index. By performing strategy evaluation calculations on different parameter combinations, a decision result sequence is obtained, and target pheromone controlled release strategies and target bait adjustment strategies are selected and generated accordingly. During the execution phase, parameters such as release time, release frequency, and release intensity of the pheromone release device inside the bait station are set according to the target pheromone controlled release strategy. Simultaneously, the physical and chemical state parameters of the bait are adjusted according to the target bait adjustment strategy, thereby generating adjusted bait station operating state data. The adjusted operating state data is continuously monitored and fed back to update the time-series hypergraph data and the bait station state prediction model, forming a closed-loop operation process.
[0138] In this embodiment, the main parameters of the DRAMA model-based reinforcement learning world model are set to a state embedding dimension of 128 and a time window length of 12. During policy evaluation, 100 parameter combinations are evaluated per round, and the policy is stably converged after 50 consecutive iterations. During the temporal hypergraph representation learning process, node state normalization uses min-max normalization, the hyperedge joint feature encoding dimension is set to 64, and the temporal modeling window length is set to 10. During model training and updates, a model parameter update is triggered after each complete running cycle.
[0139] To verify the actual improvement brought about by the present invention, the changes in key indicators of the bait station operation status before and after adjustment were compared and analyzed. The stability of pheromone release, consistency of bait status, number of termite feedings, duration of termite feeding, and coverage of feeding path were selected as evaluation indicators. The measured values and model predictions were compared within five consecutive operating cycles. The results are shown in Table 1.
[0140] Table 1. Comparison of Measured and Predicted Values of Key Indicators for Baiting Station Operation Status

[0142] As shown in Table 1, the model predictions and measured values remained relatively close throughout the continuous operating period. The bait station's operational status exhibited a continuous upward trend in key indicators such as pheromone release stability, termite feeding frequency, and foraging path coverage. This demonstrates that the present invention, through a combination of temporal hypergraph representation learning and reinforcement learning decision-making, effectively models and dynamically adjusts the termite bait station's operational status. Compared to the operation without this technology, the interruption of feeding behavior was significantly reduced, and the bait station's operational status remained stable throughout the continuous period, verifying the feasibility and technical advantages of the present invention in practical applications.
