The application discloses a virtual role behavior action prediction method and system based on a neural network, which introduces physical rules in the form of executable codes and semantic constraints in the form of hot update rule tables for double checking after model output; under the premise of not retraining the model, the mechanism of combining the high generalization ability of the neural network with the certainty of the rule engine effectively guarantees the legality, rationality and authenticity of the virtual role behavior; through integrated Grad-CAM or SHAP feature attribution analysis, a logical link from environment perception to behavior execution is established, so that the developer can accurately quantify the contribution of position and posture factors to the decision, and through the introduction of controlled disturbance at the input end, the stability is screened, so that the parameters can still remain stable under abnormal interference, and the role jitter and collapse caused by network fluctuation or abnormal operation online are avoided, and the engineering reliability of the system in a complex interactive environment is greatly enhanced.

The application discloses a meterable abnormal water use flow limiting device, which is composed of a metering module, an accumulation reset module, a trigger execution module and an external manual reset assembly. The application accurately calibrates the trigger water accumulation volume through mechanical gear matching. The automatic accumulation data zero reset is realized by relying on water stop surge during normal intermittent water use. The main waterway is automatically shut off when the continuous abnormal water leakage accumulates to the set volume, and only small flow bypass water supply is reserved. After the water leakage fault is repaired, the valve core reset and cam counting zero are completed in an integrated manner through the external manual reset handle. The application is operated in a passive mechanical mode throughout the process, does not require electric control components, can identify 0.1L / min micro leakage at the minimum, can adjust the trigger threshold value in a mechanical mode through gear matching, and solves the industry pain points that the existing passive water leakage protector cannot distinguish intermittent normal water use and continuous leakage, micro leakage detection fails and reset is complicated.

The present invention provides a secondary battery state estimation system, a secondary battery state estimation method, and a recording medium that suppress a reduction in the estimation accuracy of an internal state even when the number of parameters of the internal state of a secondary battery to be diagnosed is increased. A system (1) provided with a secondary battery state estimation device (10) is provided with an optimization unit (25) that estimates the degree of deterioration of a secondary battery (11) to be estimated. The optimization unit acquires a plurality of parameters relating to the state of the secondary battery to be estimated on the basis of voltage data (closed-circuit voltage (CCV) or open-circuit voltage (OCV)) acquired in the secondary battery to be estimated. The optimization unit performs a predetermined optimization process on at least one parameter selected exclusively from the plurality of parameters in sequence for each of the plurality of voltage regions or the plurality of capacity regions on the basis of a predetermined correspondence relationship between the plurality of voltage regions or the plurality of capacity regions and the plurality of parameters.

This application provides a method and apparatus for waste heat recovery from high-temperature solid materials. The apparatus includes a support frame with a rotary heat exchange box mounted on it. One end of the rotary heat exchange box is connected to a power unit, which is fixed to one side of the support frame. A rotating shaft is rotatably mounted on the other side of the support frame and connected to the other end of the rotary heat exchange box. A material fixing device is fixed inside the rotary heat exchange box. In this application, the power unit drives the rotary heat exchange box to rotate at a low speed, which in turn drives the material fixing device to rotate at a low speed. This causes continuous and omnidirectional relative motion and contact renewal between the heat exchange medium and the solid material, thereby achieving dynamic, uniform, and efficient direct contact heat transfer. This fundamentally solves the problems of low heat exchange efficiency and uneven cooling caused by poor contact in static filling.
