The invention discloses a fault online monitoring and early warning method for an energy storage system. The monitoring method comprises the following steps: acquiring real-time state parameters of each battery in a plurality of energy storage battery assemblies in a current detection period and a previous detection period; calculating the internal resistance change rate of the battery based on the real-time state parameters of the battery; calculating a fault risk index of the battery by combining the real-time state parameter and the aging coefficient of the battery based on the internal resistance change rate; and judging whether the fault risk index of the battery is greater than or equal to a fault risk threshold, if so, controlling the battery to stop running, and sending fault warning information to a control end of the energy storage system, and if not, controlling the battery to run normally. Through the multi-dimensional state parameters of two continuous detection periods, the fault risk index of each battery is comprehensively calculated to judge the operation state of a single battery, the problems that an existing scheme is single in detection parameter, lacks dynamic monitoring capability and does not consider battery aging factors are solved, and comprehensive, dynamic and accurate fault monitoring and early warning are achieved.

The invention discloses an AGV obstacle avoidance path planning method in an unmanned warehousing system, and the method comprises the steps: employing nested Logistic mapping and Skew Tent mapping to generate a chaotic initialization population to replace a population generation mode of a conventional differential evolution algorithm, carrying out the Levy flight operation after the selection operation, and carrying out the global path search on an environment map, thereby achieving the optimal path planning. And obtaining an AGV global feasible path avoiding obstacles in the environment map, and when the AGV has an unknown obstacle on the feasible path, re-planning the local path by adopting a dynamic window method so as to enable the AGV to realize an obstacle avoidance process in an interval where the unknown obstacle is located. The improved differential evolution algorithm enhances the global search capability through chaos initialization and a Levy flight strategy, and the AGV can quickly respond to an unknown obstacle through a dynamic window rule. The adaptability and the accuracy of path planning are improved, and the obstacle avoidance capability and the safety of the AGV in a complex environment are enhanced at the same time.

The application discloses a garden engineering full life cycle dynamic simulation and collaborative design method and system based on digital twinning and BIM. The system comprises a data acquisition layer, a unified operation model core engine, a dynamic simulation and safety prediction module, a twinning visualization platform and a real-time early warning execution module. The unified operation model integrates a plant dynamic growth sub-model, a park static environment characteristic sub-model and an external force environment dynamic load sub-model, realizing multi-time scale coupling simulation of plant long-term growth succession and instantaneous external force response. The dynamic simulation module simulates the elastic swing, plastic deformation, branch breakage and overall collapse process of plants under the action of external force (wind, snow), and accurately predicts the damage risk of collapsed plants to road personnel, power lines, buildings, waterways and other infrastructure based on spatial swept volume collision detection and damage criterion. The application realizes the intelligent leap of garden engineering from static display to dynamic prediction, from post-disposal to pre-warning.
