[0072] Figure 2 A schematic diagram of a process for binding asset basic information and generating an asset information database according to an embodiment of the present invention is shown. Figure 2 As shown, the method comprises the following steps:

[0073] Step S201, obtaining basic information of each asset when it is purchased.

[0074] Preferably, the basic information includes at least: asset name, asset model, purchase date, using department, and user.

[0075] Preferably, the basic information may also include basic technical parameters of the assets, such as size information and material information of office desks and chairs; battery size, rated power, input / output voltage / current, etc. of electronic devices.

[0076] Step S202, set an RFID tag for each asset, and write the basic information into the corresponding RFID tag through an RFID reader / writer.

[0077] Step S203, associating the electronic code of the RFID tag itself with the written basic information, and generating first tag information.

[0078] Step S204: gather the first tag information corresponding to each RFID tag.

[0079] Specifically, when an asset is put into storage, after the first tag information is generated, the RFID tag of each asset is scanned using an RFID reader / writer to read the first tag information corresponding to each asset; and the read first tag information of each asset is aggregated.

[0080] Step S205, obtaining the asset information of each asset according to the correspondence between the RFID tag and the basic information, and generating an asset information database.

[0081] Step S206, using the asset information database, complete the initial asset inventory.

[0082] Specifically, after completing the construction of the asset information database, the name, type, quantity, etc. of each asset in the database are statistically obtained, and similar assets are classified under one project.

[0083] According to the above method, the basic information of each asset is obtained when the asset is put into the warehouse, and the corresponding RFID tag is bound to each asset. Then, the information is written into the RFID tag through the RFID reader / writer to achieve the matching of each asset information. The collection of assets and corresponding data begins when the assets are first entered. Then, all the collected information is automatically transmitted and collected through the RFID reader / writer to generate an asset information database, completing the initial inventory, that is, the statistics of all asset information and corresponding assets, which greatly reduces omissions when assets are included.

[0084] Figure 3 FIG. 1 shows a flow chart of an asset information updating method based on an RFID tag according to an embodiment of the present invention. Figure 3 As shown, the method comprises the following steps:

[0085] Step S301, when the status of an asset changes, the corresponding first tag information in the RFID tag of the asset is modified according to the change to generate second tag information.

[0086] Specifically, the second tag information includes at least basic information, usage information, positioning information and / or status information in addition to the electronic code of the RFID tag itself.

[0087] Step S302: collecting second tag information in the RFID tag corresponding to each asset using an RFID reader / writer at a preset time interval.

[0088] Preferably, the preset time interval is set according to the inventory frequency actually required by different units, and is not limited here.

[0089] Step S303: modify the asset information of the corresponding asset in the asset information database according to the collected second tag information.

[0090] Specifically, the second tag information of all assets is collected at preset time intervals, and the asset information database is updated, that is, the current asset inventory is completed.

[0091] Specifically, after obtaining the second tag information of each asset, it is synchronized with the asset information database; in the information corresponding to an asset, the newly added data is added and the changed data is modified. Among them, it can be determined whether the modification of a certain data retains the original data trace according to the data type or the actual needs of the user.

[0092] For example, if you need to keep the information of all uses of an asset (user, usage duration, usage location, etc.) or the location information of the asset during its use, then the updated information will be added after the original data. If the original information does not need to be kept, then the updated information will be directly overwritten.

[0093] Preferably, the system defaults to retaining the original data traces, and the user can choose to retain or overwrite the original data according to needs.

[0094] According to the above method, through RFID technology, the inventory of assets is automatically completed at a fixed frequency, which greatly reduces labor costs and improves the efficiency and accuracy of inventory. When various changes such as use, maintenance, and scrapping occur in various assets, such information is written into the tag. The system uses RFID reading and writing equipment to collect the tag information of each asset again at a preset time interval, and synchronizes the current asset information that has changed to the database again, intelligently completes the inventory of assets, and accurately obtains the status information and location information of the current assets to understand various conditions of the current assets.

[0095] During the implementation of the above-mentioned asset information updating method, it is necessary to monitor and collect different types of asset information. Therefore, the above-mentioned RFID-based fixed asset inventory and management system requires a unit that can realize the corresponding functions.

[0096] Figure 4 FIG. 4 shows a structural block diagram of a fixed asset inventory and management system based on RFID according to another embodiment of the present invention. Figure 4 As shown, the system includes: an asset information acquisition module 401, a database generation module 402, an asset information update module 403 and a status prompt module 404; wherein,

[0097] The asset information update module 403 further includes at least: a usage monitoring unit 4031, a location monitoring unit 4032 and / or a status monitoring unit 4033; wherein,

[0098] The usage monitoring unit 4031 is used to obtain the usage instruction of the asset, determine the usage information and write it into the RFID tag.

[0099] Preferably, the usage information at least includes usage time information, user information and / or usage location information.

[0100] The location monitoring unit 4032 is used to monitor the location of the asset based on the RFID tag, generate asset location information, and update the location information in the RFID tag.

[0101] Preferably, the positioning information is acquired based on an RFID tag positioning method.

[0102] The status monitoring unit 4033 determines the current status of the asset according to the usage of the asset, generates asset status information, and writes it into the RFID tag.

[0103] Preferably, the asset status information includes at least a first status, a second status and a third status.

[0104] Specifically, according to the feedback from the user during use, determining whether the first state is normal or faulty;

[0105] Determining the second state as idle or occupied based on the asset location information and the usage information;

[0106] Determine the third state as usable or scrapped based on basic information of the asset and / or feedback from maintenance personnel;

[0107] The asset status information is written into the RFID tag; and if the asset status information includes failure, occupation and / or scrapping, it is determined that the asset is in an abnormal state.

[0108] Preferably, when an asset is damaged or scrapped, previous usage information is obtained to analyze the cause of the failure or scrapping, and the staff is prompted to manually confirm the cause of the failure or scrapping.

[0109] According to the above system, when various changes such as use, maintenance, and scrapping occur in various assets, such information is written into the tag, and the system uses the RFID reading and writing equipment to collect the tag information of various assets again at preset time intervals, and synchronizes the current asset information that has changed to the database again, intelligently completes the inventory of assets, and accurately obtains the status information and location information of the current assets to understand various conditions of the current assets, and prompts when the assets are in an abnormal state, which is conducive to making reasonable arrangements for assets based on this information again, so as to make corresponding arrangements such as use, maintenance, maintenance, and scrapping in a timely manner, greatly improving the intelligence of management, effectively preventing the loss and idleness of assets, avoiding excessive use and waste of assets, reducing the damage rate, and improving the service life and utilization efficiency of assets, thereby greatly improving the efficiency of asset inventory and management.

[0110] Regarding the state determination process in the above system, Figure 5 A schematic diagram showing a flow chart of a method for predicting asset obsolescence according to another embodiment of the present invention;

[0111] like Figure 5 As shown, the method comprises the following steps:

[0112] Step S501, obtaining basic information, usage information and theoretical service life of the asset, and determining the first durability.

[0113] Step S502, constructing an asset loss prediction model, using the scrapping history information of the corresponding using department or user when using the same type of assets as a training set, training the asset loss model, and obtaining a trained asset loss prediction model.

[0114] Preferably, the asset loss prediction model can be constructed based on the YoLov5 model and DIC technology.

[0115] Step S503, generating a second durability of the asset based on the trained asset loss prediction model.

[0116] Step S504: predicting the scrapping status of the asset based on the first durability and the second durability.

[0117] Specifically, determining weight values ​​corresponding to the first durability and the second durability respectively for the type of the asset;

[0118] Based on the obtained weight value, the first durability and the second durability are weighted to determine the asset scrapping coefficient.

[0119] H=w1×D1+w2×D2

[0120] Among them, H is the scrap coefficient; D1 is the first durability; w1 is the weight corresponding to the first durability; D2 is the second durability; w2 is the weight corresponding to the second durability.

[0121] Preferably, for consumable assets, the theoretical usage time is relatively short, and their own properties, functions and other factors have a greater impact on scrapping, so the weight w1 corresponding to the first durability should be higher than the weight w2 corresponding to the second durability;

[0122] On the contrary, for non-consumable assets, their theoretical usage time is longer, and factors such as the intensity of use during their use have a greater impact on their scrapping. Therefore, the weight w2 corresponding to the second durability should be higher than the weight w1 corresponding to the first durability.

[0123] According to the above method, based on the basic information of the asset, the theoretical service life, and the asset loss prediction model trained using the historical information of the scrapping of similar assets, a weighted calculation is performed on the durability of the asset's use to scientifically determine how long the asset can continue to be used and whether it needs to be scrapped, thereby improving the safety and efficiency of asset use.

[0161] According to the RFID-based fixed asset inventory and management method provided in this embodiment, basic information corresponding to each asset is obtained, and the basic information is written into the RFID tag bound to the asset to generate first tag information; the first tag information corresponding to each asset is aggregated to generate an asset information database containing all assets; according to the asset usage, the second tag information in the RFID tag corresponding to each asset is obtained at preset time intervals, and the asset database is updated; according to the current asset information of each asset in the asset database, the assets whose asset status is in an abnormal state are determined, and corresponding status prompts are generated. The RFID-based fixed asset inventory and management method provided in this embodiment obtains basic information of each asset when it enters the warehouse, binds a corresponding RFID tag to each asset, and then writes the information into the RFID tag through an RFID reader / writer to achieve matching of each asset information. The collection of assets and corresponding data begins when the asset is first entered, and then all the collected information is automatically transmitted and collected through the RFID reader / writer to generate an asset information database, so that all asset information and corresponding assets are counted, which greatly reduces omissions when assets are recorded. When various changes such as use, maintenance, and scrapping occur in various assets, such information is written into the tag, and the system uses the RFID reader / writer at preset time intervals to collect the asset information. Collect the tag information of each asset again, synchronize the current asset information that has changed to the database again, intelligently complete the inventory of assets, and accurately obtain the status information and location information of the current assets to understand the various situations of the current assets, which is conducive to making reasonable arrangements for assets based on this information again, and making corresponding arrangements for use, repair, maintenance, and scrapping in a timely manner, and giving prompts when assets are in abnormal conditions, greatly improving the intelligent management level, effectively preventing the loss and idleness of assets, avoiding excessive use and waste of assets, reducing the damage rate, and improving the service life and efficiency of assets, realizing the management and monitoring of the entire process and cycle of assets, and greatly improving the efficiency of asset inventory and management. In addition, based on the basic information of assets, theoretical service life, and the asset loss prediction model trained using the historical information of scrapping of similar assets, the durability of asset use is weighted and calculated, and the time for assets to continue to be used and whether they need to be scrapped is scientifically determined, which improves the safety and efficiency of asset use.
