All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The method for checking and accepting spare parts of the nuclear power station to put on the shelf, disclosed by the invention, comprises the following steps of:

s10, the warehousing server receives the arrival registration request containing the arrival information, and the arrival registration acceptance is carried out according to the arrival inspection information recorded in the arrival inspection record table displayed on the registration interface of the acceptance terminal; the arrival check record table is generated according to the arrival information in the arrival registration request; in the step, the arrival information refers to the spare part information of the nuclear power station spare parts of partial or all of the arrival in the batch of an order provided by a supplier, and in addition, the arrival information may also include the contents of whether the order is a foreign order delivery driver, a license plate number and the like; the arrival inspection information comprises abnormal information and normal information, wherein the abnormal information refers to corresponding information when the arrival information is inconsistent or the appearance is abnormal and the like in the arrival registration acceptance process; the normal information is information corresponding to a case where no discrepancy in the arrival information or no abnormality in appearance occurs. After the arrival inspection information is recorded into the arrival inspection record table, whether each spare part package passes the arrival registration acceptance check or not can be determined according to the arrival inspection information (including abnormal information and normal information) recorded in the arrival inspection record table, specifically, if abnormal information exists in the arrival inspection information corresponding to one spare part package, the acceptance check fails, and otherwise, the acceptance check passes.

S20, the warehousing server controls the automatic carrying equipment to carry the spare part packages which pass the goods registration acceptance to a preset acceptance area, informs acceptance staff matched with the spare parts of the nuclear power station in the spare part packages to carry out classification acceptance on the spare parts of the nuclear power station, and obtains classification acceptance results; wherein the automatic carrying device can automatically walk to the current position of the spare part package (the position is contained in the carrying instruction) after receiving the carrying instruction of the spare part package, and automatically complete the processes of feeding (at the current position), transporting and blanking (at the acceptance area) of the spare part package. The acceptance personnel matched with the nuclear power station spare parts in the spare part package refer to the acceptance personnel respectively corresponding to the nuclear power station spare parts of each acceptance category, namely, the types of the acceptance personnel and the acceptance modes of the acceptance personnel are different aiming at the nuclear power station spare parts of each acceptance category.

Specifically, in step S20, before the obtaining of the classification acceptance result, the method includes:

the storage server receives spare part packages of the nuclear power station spare parts scanned by the mobile scanning terminal, and acquires acceptance spare part information corresponding to each spare part package; wherein the nuclear power plant spare parts are packaged by at least one spare part package; the acceptance type information of the spare parts of the nuclear power station comprises the acceptance type of the spare parts of the nuclear power station, the name or the unique code of the spare parts of the nuclear power station (the acceptance type of the spare parts of the nuclear power station can be determined according to the name or the unique code), and the like; understandably, the information of the check and acceptance spare parts can be provided by a supplier, and can also be subjected to supplementary recording by storage personnel. Preferably, each spare part package is attached with a package label, and after the completion of the goods registration and acceptance, the package label on the spare part package is scanned through a preset scanning terminal, so that the label information and the information of the accepted spare parts corresponding to all the nuclear power plant spare parts packaged in the spare part package related to the label information can be obtained.

The storage server determines whether non-R type spare parts are packaged in the spare part package according to the information of the checked and accepted spare parts; the acceptance categories of the non-R spare parts comprise C spare parts, S spare parts and T spare parts except for the R spare parts; the R-type spare parts are spare parts which are independently subjected to conventional acceptance by storage personnel; that is, the acceptance category of the nuclear power plant spare parts in the spare part package in which the non-R-class spare parts are packaged includes at least one of R-class spare parts, C-class spare parts, S-class spare parts, and T-class spare parts. Wherein:

the R-type spare parts can be independently checked and accepted by storage personnel. The conventional acceptance content includes examination of quantity, appearance quality, description information, quality files, and the like. Class R spares generally refer to spares other than class S, class C, and class T spares.

In the above conventional acceptance process, the acceptance of the number includes: counting the quantity of the goods according to the order quantity and the order unit; the spare parts counted by weight unit need to be checked to the quantity by means of weight checking and weighing. For the supply of goods with rated package, sampling inspection can be adopted, and the bulk supply of goods must be weighed by checking weight. Bulk goods delivered by a transport vehicle (such as a tank car) are weighed twice: gross weight-tare weight; the spare parts counted by length unit are checked to the quantity by measuring with a measuring tool; the spare parts counted according to the unit of volume, volume and area need to be checked to obtain the quantity by calculation after measurement.

In the above conventional acceptance process, acceptance of the description information includes: and ensuring that all description information of the material object, the purchase order and the database is completely consistent. The main checking content comprises the following steps: checking the name, brand, manufacturer, specification, model, size, material and technical parameters of the real object to be consistent with the order; in addition, when the spare parts of the nuclear power plant have a storage life, the production date or the expiration date identifier must be checked.

In the above conventional acceptance process, acceptance of the appearance quality includes: breakage, rust, dampness, mildew, deformation, leakage, water immersion, scratches, cracks, burrs, impurities, and the like; quality document inspection and data collection:

in the conventional acceptance process, the acceptance of the quality document comprises a manufacturing completion report, a quality conformity statement, a qualification certificate, a verification report, a detection analysis report and the like of the spare parts which need to be provided by the supplier.

The C-type spare part needs the storage personnel to complete routine acceptance, and other acceptance personnel (and the technical field is matched with the technical field of the C-type spare part) except the storage personnel carry out technical acceptance of key points such as effectiveness of technology and quality files (the technical acceptance process does not need to adopt modes such as detection, test, assay and the like to carry out tests).

The S-type spare parts need to adopt detection, test, assay and other modes to determine the quality conformity and the functional integrity of the spare parts (including the spare parts needing to be sent to external detection and verification). In the process of checking and accepting the S-type spare parts, the storage personnel is required to complete routine checking and accepting, and meanwhile, other checking and accepting personnel (matched with the technical field of the S-type spare parts in the professional field) except the storage personnel carry out tests and submit test reports.

The T-type spare part is a substitute spare part of a replacement product of a certain spare part to be eliminated, which is used before, because the spare part to be eliminated is not produced; in the process of checking and accepting the T-type spare parts, the storage personnel is required to complete routine checking and accepting, and meanwhile, the replacement engineers and other checking and accepting personnel (the technical field is matched with the technical field of the T-type spare parts) except the storage personnel carry out technical checking and accepting. After the acceptance is completed, a replacement notice is generated, and further, an SAP (System Applications and products, in the present invention, an SAP server refers to a server or a server cluster which is in communication connection with the warehouse server in the nuclear power plant and can be used for managing all employee information) server modifies the main data corresponding to the spare parts to be eliminated in the SAP server according to the replacement notice.

When non-R spare parts are packaged in the spare part package, the warehousing server determines acceptance personnel who have acceptance authority on the non-R spare parts of each acceptance category according to the acceptance categories of the non-R spare parts in the spare part package, and sends acceptance notifications for accepting the non-R spare parts to the acceptance personnel in a preset mode; after the inspection personnel control unpacking of the spare part package, acquiring first inspection reports of all nuclear power station spare parts in the spare part package packaged with non-R type spare parts, and storing the first inspection reports and the inspection spare part information corresponding to the spare part package in a storage database in an associated manner; the first acceptance report comprises first acceptance data of routine acceptance of all nuclear power station spare parts in the spare part package by warehousing personnel and second acceptance data of technical acceptance of non-R type spare parts in the spare part package by the acceptance personnel; wherein, the first acceptance report also includes the classification acceptance results of all non-R-type spare parts (if R-type spare parts exist, the classification acceptance results of the R-type spare parts) in the spare part package. In this embodiment, the acceptance type of the non-R-class spare part may be determined according to the information of the accepted spare part corresponding to the nuclear power plant spare part in the spare part package, and then, different acceptance persons and different acceptance modes matched with each acceptance type are determined according to different acceptance types (and stored in the warehousing database), so as to inform the acceptance persons matched with the nuclear power plant spare parts of different acceptance types to perform classification acceptance according to different acceptance modes. The preset method can be set according to requirements, for example, the mail is sent through a mail, at this time, the confirmed acceptance personnel, acceptance method, acceptance time, acceptance position, acceptance part information of non-R spare parts needing technical acceptance included in the spare part package, and spare part information of other nuclear power station spare parts in the spare part package can be automatically filled in the preset mail template, the mail filling items needing automatic filling can be set in the preset mail template, and the storage server can automatically extract the parameter values corresponding to the mail filling items needing automatic filling from the data stored in the storage database, and automatically send the mail which is completed filling to the acceptance personnel after the parameter values are correspondingly filled in the mail template. Similarly, the voice robot may also be used to perform a telephone call notification to the acceptance officer, at this time, the confirmed acceptance officer, acceptance manner, acceptance time, acceptance position, acceptance spare part information of the non-R type spare part required to be technically accepted and contained in the spare part package, and the like may be automatically filled in the preset dialect template, the dialect filling item required to be automatically filled may be set in the preset dialect template, and the warehousing server may automatically extract the parameter value corresponding to the dialect filling item required to be automatically filled from the data stored in the warehousing database, and after the parameter value is correspondingly filled in the dialect template, automatically make a telephone call to the acceptance officer according to the filled dialect template. It should be understood that the preset manner may include, but is not limited to, one or more of the above manners, and the like, and the short message may also be sent to the acceptance staff through a similar short message template, or the instant communication information may be sent to the acceptance staff through an instant communication information template.

When only R-type spare parts are packaged in the spare part package, the warehousing server acquires second acceptance reports of all the R-type spare parts in the spare part package; and the second acceptance report comprises third acceptance data obtained by the warehousing personnel for performing conventional acceptance on all R-type spare parts in the spare part package after the warehousing personnel unpacks the spare part package. Wherein, the first acceptance report also comprises the classification acceptance results of all R-type spare parts in the spare part package. That is, when the spare part package contains the non-R type spare parts, the non-R type spare parts must be simultaneously subjected to routine acceptance by warehousing personnel and technical acceptance by technical personnel, and as long as the non-R type spare parts are contained in the spare part package, the spare part package must not be unpacked before acceptance by the acceptance personnel (i.e., the unpacked spare part package must be under the control and monitoring of professional acceptance personnel, so that the spare part package containing the non-R type spare parts is simultaneously accepted by the warehousing personnel and the acceptance personnel, for example), so as to avoid damage to personnel and supplies (such as dangerous chemicals or radioactive nuclear power plant spare parts and the like) caused by improper operation of the nuclear power plant spare parts. Meanwhile, if R-type spare parts exist in the spare part package, only the storage personnel need to perform routine acceptance check on the R-type spare parts after the box is opened. After all nuclear power station spare parts in the spare part package packaged with non-R type spare parts are completely checked, a first check and acceptance report is generated (the first check and acceptance report necessarily comprises first check and acceptance data and second check and acceptance data, the first check and acceptance data must contain check and acceptance data for regular check and acceptance of non-R type spare parts by warehousing personnel, and in the case that the R type spare parts exist in the spare part package at the same time, the check and acceptance data for regular check and acceptance of the R type spare parts by the warehousing personnel is also included), and the first check and acceptance report and label information of the spare part package are stored in a warehousing database in an associated mode. When only R-type spare parts are packaged in the spare part package, the warehousing server acquires second acceptance reports of all the R-type spare parts in the spare part package; and the second acceptance report comprises third acceptance data obtained by the warehousing personnel for performing conventional acceptance on all R-type spare parts in the spare part package after the warehousing personnel unpacks the spare part package. That is, when the spare part package only contains the R-class spare parts, the conventional acceptance of the warehousing personnel is only needed for the R-class spare parts, and at this time, the spare part package can be directly unpacked by the warehousing personnel. After all the R-type spare parts in the spare part package only containing the R-type spare parts are completely checked, a second checking report is generated (the second checking report only comprises checking data of regular checking of all the R-type spare parts by warehousing personnel), and the second checking report and the label information of the spare part package are stored in a warehousing database in an associated mode.

The embodiment realizes the orderly classification acceptance of the spare parts of the nuclear power station, improves the acceptance efficiency, saves the cost, reduces the probability of acceptance error, and further improves the safety of the nuclear power station. Understandably, after completion of the classification acceptance, an acceptance report is generated containing classification acceptance results including acceptance pass and existence of acceptance differences, all of which exist in different acceptance difference reports (an acceptance difference report is also contained in an acceptance report), and one acceptance difference report may contain one or more to-be-processed difference items.

S30, when the classified acceptance result shows that acceptance difference exists, the warehousing server obtains an acceptance difference report containing the difference items to be processed in the classified acceptance result, and performs difference processing on the difference items to be processed;

understandably, in an embodiment, the warehousing server may first determine a difference type of the difference item to be processed according to the acceptance difference report, then obtain a difference processing manner associated with the difference type according to the difference type, and then perform difference processing according to the obtained difference processing manner.

S40, when the classified acceptance result is acceptance, the warehousing server receives a packaging instruction sent by the mobile scanning terminal after scanning a temporary storage code of the spare part of the nuclear power station, extracts a packaging requirement in spare part information of the spare part of the nuclear power station, obtains packaging information generated when the spare part of the nuclear power station is packaged according to the packaging requirement, generates label information according to the packaging information and sends the label information to the mobile printing terminal, so that the mobile printing terminal can print a spare part label which is pasted on the packaged spare part of the nuclear power station; in an embodiment, the spare part tag includes a second identification code for the mobile scanning terminal to scan and identify to obtain spare part information, acceptance information, and packaging information of the nuclear power spare part, and a spare part number for characterizing an identity (such as a type of spare part) of the nuclear power plant spare part (so that the identity of the nuclear power plant spare part can be known through the spare part tag without the mobile scanning terminal). Preferably, the mobile printing terminal and the mobile scanning terminal are detachably mounted on a mobile support so as to be convenient for taking and using at any time, and inconvenience caused by carrying the mobile printing terminal and the mobile scanning terminal at the same time is avoided; the mobile printing terminal and the mobile scanning terminal are arranged on the mobile support, and the mobile scanning terminal and the mobile printing terminal are arranged on the mobile support.

In this step, the label information may include part or all of the package information, the spare part information, and the acceptance information; the spare part label can be set to be provided with a fixed label template, and at the moment, after data corresponding to all items to be filled are selected from spare part information according to the items to be filled in the label template for filling, no error is confirmed and printing is carried out; preferably, the items to be filled, which must be included in the label template of the spare part label, include information such as a spare part number, a batch, a danger level of the spare part of the nuclear power plant, a storage mode, a storage level, a packaging mode, a safety identification, whether the spare part is a controlled spare part, whether a loop forbidden material is included, and the like. In another embodiment, the content displayed in the spare part label can be selected from the label information according to the requirement.

Preferably, the obtaining of the packaging information generated when the spare parts of the nuclear power plant are packaged according to the packaging requirements includes:

the method comprises the steps that a warehousing server determines a packaging sequence according to a packaging requirement, wherein the packaging sequence comprises the packaging sequence of a plurality of packaging procedures and packaging material data related to each packaging procedure;

after receiving a standby part packaging starting instruction or a last packaging procedure finishing instruction, the warehousing server determines a current packaging procedure according to the packaging sequence, and displays the current packaging procedure and the packaging material data related to the current packaging procedure on a display interface of a mobile scanning terminal;

the storage server receives to-be-used material data obtained by scanning a spare part packaging identification code of a to-be-used spare part packaging material through a mobile scanning terminal, confirms that the to-be-used spare part packaging material is correct after the to-be-used material data is determined to be matched with packaging material data associated with the current packaging process, and displays a packaging mode of the to-be-used spare part packaging material on a display interface of the mobile scanning terminal;

the storage server acquires video data for packaging the nuclear power station spare parts by using the spare part packaging materials to be used, and stores the video data, the packaging sequence and the spare part packaging materials to be used in each packaging process in the packaging sequence in a correlated mode as packaging information.

Understandably, when the spare parts of the nuclear power station are packaged, the storage server acquires the packaging information generated in the spare part packaging process in real time, and the packaging information can be recorded in real time; in this embodiment, each spare part packaging material is provided with a spare part packaging identification code, and as long as the spare part packaging identification code of the spare part packaging material is scanned, it can be determined whether the data of the material to be used (the type, size, volume, quantity and the like of the spare part packaging material) of the spare part packaging material conforms to the data of the packaging material of one packaging process, so as to determine whether the spare part packaging material is used; meanwhile, in the embodiment, the required spare part packaging material and the packaging mode of the next packaging process in the spare part packaging process can be prompted in real time in the spare part packaging process, and the video data of the spare part packaging process is recorded (namely, the video images of the processes of selecting the spare part packaging material, the spare part packaging material and the like for the spare part of the nuclear power station belong to the packaging information), so that the packaging quality of the spare part can be detected subsequently, and the loss of the important spare part of the nuclear power station caused by errors in the spare part packaging process is avoided. After the spare part is packaged, the packaging information is stored in the database in association with the spare part information for being called up at any time.

Wherein, the packaging mode of nuclear power station spare part mainly includes: the spare parts of the nuclear power station, which are easily oxidized, corroded and deteriorated by moisture or water vapor and dust, are packaged in a moisture-proof and dust-proof way; rubber products or chemical products which are easy to age and deteriorate under illumination need to be packaged in a dark place; the nuclear power station spare parts which are easy to generate rust damage are packaged in an antirust way and coated with an antirust material; the instrument control plate is easy to cause failure of electronic components due to static electricity generation, and anti-static packaging is required; important equipment or parts are protected in a vacuum packaging mode on the basis of adopting moisture-proof or rust-proof packaging; the nuclear power station spare parts which are easily damaged (such as sealing gaskets, graphite pads and the like) by folding or extrusion need to be protected and packaged by adopting anti-folding; for equipment and materials such as pipelines, valves, containers and the like, in order to prevent foreign matters from entering from a port or an inlet to cause pollution, the equipment and the materials need to be packaged in a port plugging mode. Preferably, when the warehousing server recognizes that the original spare part package meets the packaging requirement of the nuclear power station spare part (repackaging by adopting the original spare part package) or recognizes that the unpacking prohibition prompt of the supplier (unpacking is required to be performed by professional technicians and repackaged by using the original spare part package in the classification and verification) by scanning the package identifier on the original spare part package of the nuclear power station spare part, the original spare part package needs to be reserved. Parts of the nuclear power plant spare parts which are corrosion-resistant or not required to be packaged do not need to be packaged and stored, and the package information remarked on the label information can be packaging-free.

And S50, after receiving a racking instruction sent by the mobile scanning terminal after scanning the spare part label, the warehousing server stores the spare parts of the nuclear power station into a rack selected according to the storage requirement of the spare parts of the nuclear power station. That is, receiving the racking instruction sent by the mobile scanning terminal scanning the spare part label, it can be stated that the spare part of the nuclear power station needs to be racked at present, and at this time, whether the racking shelf meets the storage requirement of the spare part of the nuclear power station needs to be considered, so that the storage requirement is called first, so that the storage condition of the shelf is compared with the storage condition of the shelf subsequently, and whether the storage condition of the shelf meets the storage requirement is confirmed. The shelf information is obtained after the spare parts of the nuclear power plant are placed on the shelf and the spare part labels are scanned by a fixed scanning device arranged in the shelf (one shelf is provided with one fixed scanning device, so that the shelf information of the shelf on which the spare parts of the nuclear power plant are placed can be confirmed as long as the spare parts of the nuclear power plant placed in the shelf are scanned by the fixed scanning device); the shelf information is obtained by scanning the labels of the spare parts through the fixed scanning device in the shelf, the shelf information can be uploaded after the spare parts of the nuclear power station enter the shelf, and therefore the situation that when the spare parts of the nuclear power station on the shelf are too many and are easy to confuse, the shelf information is scanned before the spare parts are put on the shelf, and the situation that the subsequent spare parts of the nuclear power station on the shelf are not the spare parts of the nuclear power station corresponding to the putting-on instruction when the shelf information is matched with the storage requirement is avoided, and finally the shelf information is wrong.

Further, after the spare parts of the nuclear power plant are placed on the shelf, the warehousing server judges whether shelf information sent after the spare part labels of the spare parts of the nuclear power plant are scanned through a fixed scanning device arranged in the shelf is received within a preset time; when the shelf information sent by the fixed scanning device is not received within the preset time (the preset time can be set according to requirements), the warehousing server receives the shelf information sent by the mobile scanning terminal after scanning the shelf identification code on the shelf; and the warehousing server matches the shelf information sent by the mobile scanning terminal with the storage requirement, and if the matching is successful, the shelf information sent by the mobile scanning terminal and spare part information of the spare parts of the nuclear power station are stored in the database in a correlation manner. That is, in this embodiment, a shelf identification code may also be set on the shelf, and if the fixed scanning device is damaged or the signal is interrupted and the fixed scanning device cannot feed back the shelf information, the shelf identification code on the shelf may also be scanned by the mobile scanning terminal to further identify the shelf information. In some embodiments, the shelf identification code may also be scanned directly by the mobile scanning terminal to identify shelf information.

The invention can realize the orderly acceptance of the nuclear power station materials, improves the acceptance efficiency, saves the cost, reduces the error probability and further improves the safety of the nuclear power station. In the process of classifying and checking the spare parts of the nuclear power station, classification and checking can be performed according to different characteristics of various spare parts, so that various different materials to be checked enter different checking and checking processes. The packaging and racking mode of the spare parts of the nuclear power station can ensure that no mistake is made in the packaging and racking process, and also ensures that the spare parts can be properly stored and cannot be damaged, thereby avoiding the loss and safety risk caused by the damage of the spare parts of the nuclear power station.

In one embodiment, the incoming inspection information includes exception information and normal information; in step S10, the checking and accepting the incoming shipment according to the incoming shipment inspection information entered in the incoming shipment inspection record form displayed on the registration interface of the checking and accepting terminal includes:

the storage server receives an identification image of a goods arrival identification on the spare part package scanned by a storage worker through the mobile scanning terminal and an actual goods arrival image of the appearance condition of the spare part package shot by preset shooting equipment;

the warehousing server acquires an original image of the spare part package from the arrival information, and simultaneously acquires package checking information (including the number, the type and the like of the spare part package) acquired after image recognition is carried out on the identification image;

the warehousing server detects whether the package checking information of the spare part package conforms to the arrival information and detects whether the actual arrival image is matched with the original image (the completeness of the spare part package is verified);

when the package checking information is inconsistent with the arrival information or/and the actual arrival image is failed to be matched with the original image, the warehousing server records abnormal information in an arrival check record table displayed on a registration interface of the acceptance check terminal, and then records the arrival registration acceptance check record of the spare part package as acceptance check abnormality; the abnormal information comprises first abnormal information or/and second abnormal information; the first abnormal information is inconsistent information between the package checking information and the arrival information; the second abnormal information is matching failure information between the actual arriving image and the original image (appearance abnormal conditions such as damage, rain, water immersion, mildew and the like of spare part packages appear in the actual arriving image);

when the package checking information is consistent with the arrival information and the actual arrival image is successfully matched with the original image, the warehousing server records the consistent package checking information and the actual arrival image as normal information in an arrival check record table displayed on a registration interface of the acceptance terminal, and the arrival check record of the spare part package is accepted.

Understandably, if the inspection and acceptance of the spare part package (for example, the quantity and the type are not consistent, the spare part package is damaged and the like) exists in the process of the arrival registration and acceptance of the spare part package, the warehousing server automatically feeds back the abnormal information to the preset arrival abnormal processing party. If there is no arrival abnormality, the flow proceeds to step S20.

In one embodiment, one acceptance difference report corresponds to at least one pending difference term;

in step S30, the obtaining an acceptance difference report including a to-be-processed difference item in the classification acceptance result, and performing difference processing on the to-be-processed difference item includes:

determining a difference type of each to-be-processed difference item in the acceptance difference report;

and acquiring a difference processing mode associated with the difference type according to the difference type, and correspondingly performing difference processing on each to-be-processed difference item in the acceptance difference report according to the acquired difference processing mode.

Understandably, the difference types of the difference items to be processed of the nuclear power plant spare parts (each difference type can be further refined) comprise a quantity difference type, a quality difference type, a description information inconsistency difference type and a quality file difference type.
