The invention belongs to the related technical field of vehicle charging scheduling, and provides a vehicle charging dynamic scheduling method and system for a charging pile fault in order to solve the problem that a charging device cannot respond in time after a fault occurs, and the method comprises the following steps: monitoring the operation state of each charging pile in the execution of an initial charging scheduling scheme in real time; identifying a target vehicle set influenced by the charging pile fault; calculating an emergency priority score of each target vehicle according to the residual electric quantity and the planned departure time of the target vehicle; constructing a dynamic resource profile of the available charging pile based on the residual available power of the available charging pile, and screening a feasible candidate pile set; and according to the vehicle priority queue, reallocating available charging piles to each target vehicle in sequence by taking the minimum cost as a target, and generating a rescheduling scheme. According to the invention, charging of the vehicle at the valley point of the electricity price can be guaranteed to the greatest extent, and the reliability, economy and adaptive capability of charging are remarkably improved.

The application discloses a novel feeding device for laterite nickel ore, which comprises a rotating platform, a material pouring platform and a grabbing mechanism. A partition is arranged on the top of the rotating platform, so that the top of the rotating platform is divided into a first stacking pit and a second stacking pit. The rotating platform is used for rotating the first stacking pit and the second stacking pit to replace positions. The material pouring platform is arranged on both sides of the first stacking pit, and a stacking mechanism is arranged on the material pouring platform and used for pushing the materials on the material pouring platform from both sides to the stacking pit in the middle. The novel feeding device for laterite nickel ore provided by the application can pour materials for multiple transport vehicles side by side through the material pouring platform, and the materials can be concentrated and stacked in the stacking pit in the middle through the stacking mechanism. Then, the two stacking pits are replaced through the rotating platform, and the grabbing mechanism is used for grabbing and feeding the mineral materials, so that the transport vehicles are avoided from queuing, and the efficiency of pouring the mineral materials is improved.

This invention discloses an ophthalmic device, including a movable chassis, a main unit integrating vision testing and refractive error detection functions, and a main unit drive mechanism. The main unit includes a main unit housing, a main unit cover, and a cover drive mechanism. The ophthalmic device has vision testing and refractive error detection functions and is equipped with a movable base. The entire device can be moved to designated locations as needed, facilitating use, especially in schools where it can be moved sequentially to each classroom for vision checks, avoiding queuing and congestion, and improving examination and testing efficiency. The main unit can be raised and lowered relative to the movable chassis, and the main unit cover can be raised and lowered relative to the main unit housing. The viewing window is located on one side of the main unit cover, thus enabling two-stage height adjustment to meet the examination and testing needs of users of different heights. Therefore, no external lifting drive mechanism is needed to move the entire ophthalmic device up and down, freeing up the device for transfer between different locations for examination and testing.

This invention discloses a mining vehicle dispatching system and method, belonging to the field of mining transportation dispatching technology. It includes a perception layer, a decision-making layer, an execution layer, and an interaction layer. The perception layer accurately acquires multi-source key information about vehicles and excavators and uploads this information to the decision-making layer. The decision-making layer, connected to the perception layer, constructs a vehicle-excavator digital twin mapping through data fusion, executes the tiered cyclic charging rules for electric mining trucks, and makes loading point decisions based on multi-dimensional cost modeling, generating dispatching instructions. The execution layer, connected to the decision-making layer, transmits dispatching instructions in real-time via hierarchical voice and feeds back the execution status to the decision-making layer. The interaction layer, connected to the decision-making layer, centrally displays vehicle status and dispatching progress, and supports switching from automatic dispatching mode to manual dispatching mode under triggered conditions, with manual dispatching instructions having higher priority than automatic dispatching instructions. This invention achieves efficient and accurate mining transportation dispatching.

This invention discloses a vehicle charging planning method and related equipment based on charging stations. The main objective is to address the problems of insufficient charging stations leading to inefficient and inefficient charging station configuration, resulting in long waiting times for vehicles, and the issue that relying solely on charging station-level planning introduces significant uncertainty when the vehicle is at a certain distance from the charging station, potentially causing planning failures or requiring multiple replanning attempts. The method includes: obtaining the current battery level of the target vehicle; if the target vehicle's current battery level is lower than a preset level, querying the charging status of charging stations within a preset range of the target vehicle, including charging station occupancy status, navigation data of the currently charging vehicle, and its current battery level; and determining the target charging station based on the charging station occupancy status, the vehicle's navigation data, and its current battery level.

The invention relates to a charging pile operation system and method, and belongs to the technical field of new energy charging. According to the scheme, after a charging demand sent by a user terminal and the current position of a user are received, a target charging pile is matched for the user according to the occupancy state of the charging pile within a set range around the current position of the user; calling a map of an area where the user is located, generating AR navigation data from the current position of the user to the position of the target charging pile according to the positions of the user and the target charging pile in the map, and sending the AR navigation data to the user terminal; and after the identity of the user arriving at the target charging pile is confirmed, binding is completed based on biological characteristics or multi-mode non-inductive payment bound by the vehicle, charging is started, and money is automatically deducted after charging is completed. According to the method and the system, the pile finding convenience and the payment efficiency are improved, resource optimization configuration is realized through intelligent matching, a visual and accurate charging pile navigation service is provided for a user through AR navigation, the user is helped to quickly find the charging pile in a complex environment, and the finding time is shortened.
