Referring to fig. 1, the invention provides a digital warehouse management system for spare parts of a nuclear power station, which comprises a warehouse module, a scheduling module and a logistics module; the storage module circulates materials of spare parts of the nuclear power station through a vertical warehouse of the storage module; the scheduling module generates scheduling logic for material circulation; the logistics module executes the dispatching logic of the dispatching module, so that the materials are circulated in the vertical warehouse according to the dispatching logic; wherein the scheduling module determines scheduling logic for the material to execute in the vertical based on the enterprise resource planning SAP for the material.

The vertical warehouse comprises a plurality of subareas, namely a receiving and checking area, an upper shelf quality inspection area, a disqualified withdrawal area, a storage area, a picking area and a delivery area, wherein materials sequentially circulate along the receiving and checking area, the upper shelf quality inspection area, the disqualified withdrawal area, the storage area, the picking area and the delivery area, and the vertical warehouse determines the occupation area of each subarea according to the occupation area and the occupation time of the materials in each subarea. The receiving and checking area, the shelf quality inspection area and the unqualified returning area are arranged adjacent to each other and are positioned on one side of the storage area, and the sorting area and the delivery area are arranged adjacent to the other side of the storage area.

In this embodiment, the scheduling logic executed by the warehouse management system on the materials is determined according to the material demand condition corresponding to the SAP, and a flow operation mode is formed in the material circulation process, so that each operation environment from warehouse entry to warehouse exit of the materials in a flow operation mode is from front to back, and the materials are not intersected with each other, thereby ensuring the maximization of efficiency and the reliability of stable operation. Meanwhile, in different areas of the vertical warehouse, the occupied area and occupied time of corresponding materials are determined based on SAP (super-absorbent polymer), so that the occupied area of the materials in the actual unit time is calculated, and the actual area and the azimuth of each area are effectively planned by combining the total area of the vertical warehouse; the material is circulated in a running mode of one flow, and the material is matched with the requirements of the material corresponding to SAP in the production line end in real time, so that the material is produced along with the production line. Similarly, the material corresponding to the SAP can be matched with the material requirement of the maintenance operation, so that the circulation efficiency of the material of spare parts in the storage of the spare parts in the maintenance operation of the nuclear power station is optimized.

Referring to fig. 2 to 6, in an overall layout of an embodiment of the present invention, materials of spare parts of a nuclear power plant are divided and planned in different areas according to the ratio of the temporary storage time of the actual materials in each area to the reduced occupied area. In the vertical warehouse of the storage module, the low-level elevator of the logistics module can be used for feeding a container loaded with materials such as a tray by a manual forklift, and the automatic code scanning gun can identify the two-dimensional code of the tray in the lifting process of the low-level elevator, and basic information of the materials is bound into the corresponding two-dimensional code of the tray by an operator through a PDA before the two-dimensional code information is put on the shelf.

After the code scanning of the previous pallet is finished, the pallet automatically flows to the next chain conveying line of the logistics module, the sensors with the appearance detection and weighing functions are arranged on the next chain conveying line, the length, width and weight ranges of cargoes (pallets and materials in the pallets) can be compared with set values, if the cargoes are unqualified, the chain conveying line is withdrawn, and the materials in the pallets can be rearranged by operators, so that the size and weight requirements of the cargo specification can be met; qualified trays and materials in the trays enter a telescopic fork type special loading and unloading machine of the logistics module and are moved to an AGV moving frame, so that transition from the trays to the moving frame is realized.

Unqualified materials after quality inspection are sent to an unqualified material returning area of a vertical warehouse through an AGV, a special telescopic fork type loading and unloading machine is automatically connected with the AGV, the tray (containing materials) on the AGV moving frame is forked to a rear-end chain machine, an operation staff waits for forking the tray (containing materials) on the chain machine, meanwhile, a PDA scans tray code information, the bound material information is returned to a WMS system, and then the bound material information is transmitted to an SAP operation information for updating.

The telescopic fork type loading and unloading special plane is used for transporting the tray (containing materials) on the AGV moving frame to the rear end chain machine, when the rear end chain machine is transmitted to the front section chain conveying line of the lifting machine, the tray (containing materials) is transported to the connection position of the conveying chain machine with the corresponding layer number of the goods frame according to the WMS distribution task, and the tray (containing materials) is transported to the appointed position of the WMS neutral warehouse through the four-way vehicle/stacker of the logistics module according to the WCS instruction of the storage control system.

Referring to fig. 1, in one embodiment, the scheduling logic includes a warehouse management system WMS scheduling logic and a warehouse control system WCS scheduling logic; the WMS scheduling logic is used for selecting a circulation mode of the materials; the WCS scheduling logic is used for controlling the logistics module to execute corresponding actions according to the circulation mode selected by the WMS scheduling logic.

The circulation mode of the material comprises the following steps: a receiving mode, a tally mode and a warehouse-out mode; the receiving pipe mode is used for receiving the material corresponding to the SAP to the receiving and checking area in advance; the material management mode is used for managing materials to a first layer of the vertical warehouse in advance according to the SAP; the ex-warehouse mode is used for forwarding materials in advance according to SAP from a storage area to an ex-warehouse conveying area through a picking area.

In the pipe receiving mode, the material receiving in advance is to lead the material corresponding to the SAP to arrive in advance for a preset time (for example, 2 days); in a tally mode, the material is tally to the first layer of the vertical warehouse in advance, wherein the material is the SAP corresponding to the current day of material taking or the next day of material taking; in the out-warehouse mode, the advance flow turns to sort and convey the material corresponding to the SAP in advance for, for example, 3 hours.

The corresponding circulation modes of the WMS scheduling logic are the 3H mode, the T+2 mode and the T or T+1 mode.

It should be noted that, the ex-warehouse mode may be selected as a "3H mode", in which the materials to be ex-warehouse are sorted and transported 3 hours in advance, because the complexity of ex-warehouse management of the spare parts of nuclear power is the planning work order, the lead person needs to fill in the item lead order or borrow the order, and transact the relevant approval procedure, after the warehousing personnel verifies that the procedures are complete, the two parties in advance click the names, specifications, quantity and the like of the distributed items on the same face in advance, confirm that the items meet the replacement requirement, and then get the materials to the planning time and maintain the machine set; especially, during overhaul, the spare parts are large in demand, and various required items need to be selected in advance so as to ensure that the material demands corresponding to the SAP can be met.

The receiving mode may be selected as "t+2 mode", where "T" means arrival date and "2" means day of arrival, and means arrival of the material two days in advance, and this time is specified according to the arrival amount of the material and company check to ensure stability of the material supply chain in the WMS.

The tally mode can be selected as a T or T+1 mode, wherein T refers to material receiving time, and nuclear power materials are planned receiving materials, namely T is current receiving materials, and T+1 is next current receiving materials; it is different from the meaning of "t+2" in the take-up mode, and "T" in "t+2" is the arrival time.

Similarly, the WCS scheduling logic is correspondingly used for carrying out information interaction with the WMS, receiving a task of the WMS, and sending a task instruction of the WMS to the bottom layer PLC, so that the automation equipment of the logistics module is driven to execute corresponding actions, and the multi-layer multi-car or stacker high-efficiency scheduling system of the four-way car is controlled in the vertical warehouse to complete material circulation.
