This disclosure provides an order query method, apparatus, device, and storage medium. The method includes: responding to a received first operation, determining a target order with a query requirement; then processing the target order separately based on the inventory quantity of materials corresponding to the target material type in the inventory; and then, responding to a received second operation, determining and outputting the processing status of the target order based on material balance accounting. The technical solution of this disclosure solves the problem in related technologies where the accounting of materials corresponding to orders easily leads to the inability to trace the source of materials, resulting in material inventory backlog. It effectively avoids abnormal inventory management situations such as order demands not being met in a timely manner, unclear source of inventory materials, or mismatch between demand and inventory, reducing inventory backlog and improving inventory turnover and management efficiency.

This invention belongs to the field of calcium carbide furnace electrode material supply technology, and discloses a precise metering method and device for calcium carbide furnace electrode material supply, including the following steps: real-time monitoring of the opening status of the unloading vibrating feeder below the weighing hopper, the extension status of the scraper at the hopper inlet, and the real-time material level of each hopper; when the material level of any target hopper is lower than a preset threshold, a feeding signal is triggered to start cyclic feeding until the material level of the target hopper reaches a preset upper limit; the furnace output data corresponding to each phase electrode is collected, and the cumulative total feed of each phase electrode is compared and analyzed with the output data to calculate the material balance deviation and generate output data. By synchronously collecting the feed amount data of the corresponding phase electrode at the moment when the unloading feeder issues a unloading signal and the scraper at the hopper inlet issues an extension signal, and successively accumulating and precisely metering the feed amount of the surrounding hoppers to which the electrode belongs, the independent accounting of the total feed amount of a single phase electrode is realized.

This application provides a material movement balancing method, apparatus, electronic device, and storage medium. By acquiring node model information of a node model, which consists of at least two processing nodes corresponding to physical nodes in the material production and supply process, the node model information characterizes the predicted material change at each physical node during the material flow between the processing nodes. Based on the node model information and a preset time period, node constraint information is obtained, characterizing the target material loss at each node model during the material flow between the processing nodes. Based on the node constraint information, a target balance arbitration value is obtained, which is used to determine whether the material loss between the physical nodes is balanced during the material flow between the processing nodes, thus solving the problem of low accuracy in material balance results.
