Description

Technical Field

[0001] The present invention relates to the technical field of asset management, and in particular to a fixed asset management method, device and system. Background Art

[0002] Fixed assets refer to non-monetary assets held by enterprises for the purpose of producing products, providing services, leasing or operating management, which have a use period of more than 12 months and reach a certain standard of value, including houses, buildings, machines, machinery, transportation tools and other equipment, appliances and tools related to production and operation activities. Fixed assets are the means of labor of enterprises and the main assets on which enterprises rely for production and operation.

[0003] The current method of fixed asset management is to use electronic tags, such as RFID (Radio Frequency Identification) tags, to enter the information of fixed assets, scan the identification code of the electronic tag through a reader and upload it to the computer device, and realize fixed asset management without manual inventory through data interaction.

[0004] When the asset manager scans the electronic tags along the planned path using this method, on the one hand, the electronic tags that have been scanned are scanned repeatedly, and on the other hand, the electronic tags with weaker signals among the unscanned electronic tags are not scanned more intensively, resulting in missed scans. This leads to the problem of unreasonable scanning of electronic tags in fixed asset management. Summary of the invention

[0005] Based on this, it is necessary to provide a fixed asset management method, device and system to address the above-mentioned problems.

[0006] The embodiment of the present invention is implemented as follows: a fixed asset management method, the fixed asset management method comprising:

[0007] Tag creation process: Generate fixed asset usage information based on fixed asset purchase applications and fixed asset usage, and match the fixed asset usage information with RFID tags;

[0011] generating a time-limited sleep instruction according to the number of times the scanned RFID tag is scanned and sending the command to the scanned RFID tag to stop the communication between the scanning device and the scanned RFID tag;

[0012] Generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately;

[0013] Information update process: Update the usage information of the fixed assets corresponding to the RFID tag according to the scanning results of the scanning device.

[0016] For each RFID tag, associating the RFID tag with nearby RFID tags;

[0017] The tag scanning module is used to send a common scanning instruction to the scanning device every first preset time and obtain the RFID tag scanned by the scanning device and the number of times the RFID tag is scanned;

[0018] Determine the missed RFID tags according to the scanned RFID tags and the RFID tags associated therewith;

[0019] generating a time-limited sleep instruction according to the number of times the scanned RFID tag is scanned and sending the command to the scanned RFID tag to stop the communication between the scanning device and the scanned RFID tag;

[0020] Generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately;

[0026] A fixed asset management method provided by an embodiment of the present invention is to associate the usage information of fixed assets with RFID tags during the tag establishment process, and then, for each RFID tag, associate the RFID tag with the RFID tags nearby; during the tag scanning process, determine the RFID tags that are missed according to the scanned RFID tags and the RFID tags associated with them; generate a time-limited sleep instruction according to the number of times the scanned RFID tags are scanned and send it to the scanned RFID tags to stop the communication between the scanning device and the scanned RFID tags; generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately; during the information update process, update the usage information of the fixed assets corresponding to the RFID tags according to the scanning results of the scanning device.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] It is understood that the terms "first", "second", etc. used in the present invention may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script without departing from the scope of the present invention.

[0033] like Figure 1 As shown, in one embodiment, a fixed asset management method is proposed, which may specifically include the following steps:

[0034] Tag creation process: Generate fixed asset usage information based on fixed asset purchase applications and fixed asset usage, and match the fixed asset usage information with RFID tags;

[0035] For each RFID tag, associating the RFID tag with nearby RFID tags;

[0036] Tag scanning process: every first preset time, send a common scanning instruction to the scanning device and obtain the RFID tags scanned by the scanning device and the number of times they are scanned;

[0037] Determine the missed RFID tags according to the scanned RFID tags and the RFID tags associated therewith;

[0038] generating a time-limited sleep instruction according to the number of times the scanned RFID tag is scanned and sending the command to the scanned RFID tag to stop the communication between the scanning device and the scanned RFID tag;

[0039] Generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately;

[0040] Information update process: Update the usage information of the fixed assets corresponding to the RFID tag according to the scanning results of the scanning device.

[0041] In this embodiment, the fixed assets may be enterprise assets such as tables, chairs, display screens, and mainframes.

[0042] In this embodiment, the fixed asset purchase application is an application submitted by the user department when purchasing fixed assets, which includes the basic information of the fixed assets such as the product name, model, specification, purchase amount, precautions, and application reason of the fixed assets. The basic information of the fixed assets is determined when the fixed assets are purchased and is immutable information.

[0043] In this embodiment, the usage of fixed assets is determined after the fixed assets arrive at the enterprise, and the usage of fixed assets includes the name of the fixed assets, the start time of use of the fixed assets, the accumulated depreciation, the current valuation, the use location, the use department, the user, etc. The usage of fixed assets can be changed, and the information update process is essentially to update the usage of fixed assets.

[0044] In this embodiment, each RFID tag used has a unique identification code, namely, a UID code, which is written by the manufacturer during the production process of the RFID tag and is generally unchangeable. Matching the usage information of the fixed asset with the RFID tag is essentially matching the usage information of the fixed asset with the unique identification code of the RFID tag. The unique identification code of the RFID tag has nothing to do with the usage information of the fixed asset, but is only used as an identification mark for the usage information of the fixed asset. For example, if the unique identification code of the RFID tag is 0001, and the fixed asset is display screen 1, then the usage information of display screen 1 is matched with the RFID tag of 0001. When the RFID tag of 0001 is scanned, the usage information of display screen 1 can be known.

[0045] In this embodiment, matching the usage information of fixed assets with RFID tags is essentially matching the fixed assets with RFID tags, that is, by determining the RFID tag, the usage information of the corresponding fixed assets can be determined, and the corresponding fixed assets can also be determined.

[0046] In this embodiment, the RFID tag is associated with only the unique identification code of the RFID tag, and no association is made with the usage information of the fixed asset corresponding to the RFID tag. For example, an RFID tag with a unique identification code of 0001 is associated with an RFID tag with a unique identification code of 0002. The fixed asset corresponding to the RFID tag of 0001 is display screen 1, and the fixed asset corresponding to the RFID tag of 0002 is display screen 2. When the RFID tag of 0001 is scanned, only the corresponding fixed asset is known as display screen 1 and the associated RFID tag of 0002, but display screen 2 cannot be known. Display screen 2 can be known only when the RFID tag of 0002 is scanned.

[0047] In this embodiment, the label creation process generally occurs when a new fixed asset is allocated or when an old fixed asset is changed. For example, a new fixed asset is set to a certain location and then the label creation process for the fixed asset begins, the location of the old fixed asset is greatly changed, or the label of the old fixed asset is damaged.

[0048] In this embodiment, the tag scanning process can be performed once a month or once a quarter, such as a monthly or quarterly inventory. The information update process is generally performed after the tag scanning process is completed. Since the tag scanning has a long time interval, such as one month, the information update has a certain lag.

[0049] In this embodiment, the tag scanning process is that the manager moves along the planned route with the scanning device to scan the RFID tag, so the sign of the end of the tag scanning process is that the manager has walked the entire planned route.

[0050] In this embodiment, the first preset time can be set to any value in the range of 1-10s, for example, 5s. Generally speaking, the manager holds a scanning device to scan along the planned route. The scanning device scans very quickly, and the same RFID tag can be scanned multiple times within the first preset time, so there is no need to obtain the RFID tags scanned by the scanning device all the time. The scanning device is a combination of an RFID reader and an antenna.

[0051] In this embodiment, when the scanning device receives the general scanning instruction, it sends a radio frequency signal to all RFID tags. All RFID tags that are not in a dormant state can return a signal to the scanning device after receiving the radio frequency signal so as to be recognized by the scanning device. This radio frequency signal is not targeted at a specific RFID tag, but for all RFID tags, including those in a dormant state, only the dormant RFID tags will not return a signal. Therefore, this general scanning instruction can be understood as a start instruction without a specific RFID tag, similar to starting a scan.

[0052] In this embodiment, acquiring the RFID tag scanned by the scanning device is essentially acquiring the unique identification code of the RFID tag scanned by the scanning device.

[0053] In this embodiment, the surrounding environment, such as metal objects, electromagnetic interference, etc., may affect the transmission and reception of RFID tag signals; or signal conflicts may occur between multiple RFID tags; or there may be quality problems with RFID tags, such as unstable signals, damaged RFID tags, etc. These problems are all reasons for RFID tags to miss scanning.

[0054] In this embodiment, scanning the missed RFID tags separately does not mean that the manager uses the scanning device to scan the missed RFID tags, but the computer device controls the scanning device to automatically scan the missed RFID tags separately. There are two scanning results, one is that the missed RFID tags are scanned; the other is that the missed RFID tags are still not scanned. This may be that the RFID tags are damaged or the signal is so poor that they cannot be scanned, or the RFID tags may be on a planned route that has not been taken. If the RFID tag is on a planned route that has not been taken, although it is a missed RFID tag at this time, it will eventually be scanned as the manager moves.

[0055] In this embodiment, during the information updating process, the updated information may be updated manually, or the program may automatically update the information in the preset table according to the administrator.

[0056] A fixed asset management method provided by an embodiment of the present invention is to associate the usage information of fixed assets with RFID tags during the tag establishment process, and then, for each RFID tag, associate the RFID tag with the RFID tags nearby; during the tag scanning process, determine the RFID tags that are missed according to the scanned RFID tags and the RFID tags associated with them; generate a time-limited sleep instruction according to the number of times the scanned RFID tags are scanned and send it to the scanned RFID tags to stop the communication between the scanning device and the scanned RFID tags; generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately; during the information update process, update the usage information of the fixed assets corresponding to the RFID tags according to the scanning results of the scanning device. In this way, the association relationship between the RFID tags is first established, and then the missed RFID tags are determined during the scanning process of the scanning device according to the association relationship between the RFID tags, and the repeated scanning of the scanned RFID tags is stopped, and the missed RFID tags are scanned more intensively, so as to solve the problem of unreasonable scanning of electronic tags in fixed asset management.

[0057] In one embodiment, generating fixed asset usage information according to the fixed asset purchase application and the usage of the fixed assets includes:

[0058] Determine the basic information of fixed assets based on fixed asset purchase requisition;

[0059] Determine the usage of fixed assets based on the information of fixed assets in the preset table;

[0060] Generate fixed asset usage information by combining the basic information of fixed assets and the usage of fixed assets.

[0061] In this embodiment, the preset form is a template form established by the enterprise for fixed assets. After the fixed assets arrive at the enterprise, the management personnel fill in each item in the preset form to form the usage of the fixed assets. The content of the preset form includes the tag name of the fixed asset, the start time of use of the fixed asset, the accumulated depreciation, the current valuation, the usage location, the using department, the user and other items.

[0062] In one embodiment, for each RFID tag, associating the RFID tag with nearby RFID tags includes:

[0063] For each RFID tag A, obtain the RFID tag B scanned by the scanning device when the scanning device is close to the RFID tag A;

[0064] Sort the RFID tags other than RFID tag A in RFID tag A from large to small according to signal strength;

[0065] Obtain a preset number of RFID tags C that are at the front of the sort;

[0066] RFID tag C is associated with RFID tag A as a subordinate.

[0067] In this embodiment, the preset number may be any integer between 1 and 5.

[0068] In this embodiment, the scanning device is close to RFID tag A, and the scanning device can be regarded as being at the position of RFID tag A. The closer to the scanning device, the higher the signal strength. All obtained RFID tags C can be regarded as RFID tags near RFID tag A.

[0069] In this embodiment, the sorting can also be performed from most to least according to the number of scans, or the number of scans and signal strength are combined to perform the sorting. The purpose of the sorting is only to obtain a preset number of RFID tags C at the front of the sorting to associate with the RFID tag A, and the purpose of the association is to find out the RFID tags that are missed, so the association relationship can also be customized in nature. For example, the RFID tag corresponding to the display screen 1 is associated with the RFID tag corresponding to the mouse 1.

[0070] In one embodiment, the step of determining the missed RFID tags based on the scanned RFID tags and the RFID tags associated therewith includes:

[0071] Determine the RFID tag associated with the scanned RFID tag, recorded as a secondary tag;

[0072] For each secondary tag, it is determined whether the secondary tag is scanned by the scanning device. If not, the status of the secondary tag is changed to missed scanning, and the secondary tag is recorded as a missed scanning RFID tag.

[0073] In this embodiment, for example, the RFID tags associated with RFID tag 0001 include RFID tag 0002 and RFID tag 0003, then RFID tag 0002 and RFID tag 0003 are secondary tags of RFID tag 0001. If RFID tag 0002 exists but RFID tag 0003 does not exist among the scanned RFID tags, then RFID tag 0002 is not a missed scan tag, and RFID tag 0003 is a missed scan RFID tag. At this time, the status of RFID tag 0003 is changed to missed scan. The status of RFID tags includes scanned, unscanned, and missed scan.

[0074] In this embodiment, if the secondary tag is scanned by the scanning device, no operation needs to be performed.

[0075] In one embodiment, generating a time-limited sleep instruction according to the number of times the scanned RFID tag is scanned and sending the instruction to the scanned RFID tag to stop the communication between the scanning device and the scanned RFID tag includes:

[0076] For each scanned RFID tag, determining whether the number of times the scanned RFID tag has been scanned exceeds a preset number, and if so, generating a time-limited sleep instruction for the scanned RFID tag according to a second preset time;

[0077] A time-limited sleep instruction of the scanned RFID tag is sent to the scanned RFID tag by the scanning device to stop the communication between the scanning device and the scanned RFID tag.

[0078] In this embodiment, the preset number of times can be set to 10. If the number of times an RFID tag is identified reaches the preset number of times, then it can be considered that the RFID tag has no problem and can be stably identified. Generally speaking, within a first preset time, the number of times an RFID tag is identified reaches the preset number of times, unless the signal is very poor, for example, the RFID tag is far away from the scanning device. In the planned route, it is ensured that all RFID tags on the planned route are at a suitable distance from the planned route and are easy to scan. If the signal is very poor, it may be that the RFID tag belongs to a planned route that has not been passed, or there may be a signal conflict between RFID tags.

[0079] In this embodiment, if the number of times the scanned RFID tag is scanned does not exceed the preset number of times, no operation is performed on the scanned RFID tag.

[0080] In this embodiment, the second preset time can be set to 10 minutes, which can ensure that the RFID tags scanned within several first preset times will be in a dormant state and will not send a return signal to the scanning device to be scanned by the scanning device, thereby reducing the repeated scanning of RFID tags that have already been scanned. This also causes a large amount of idle time in the communication time slot of the scanning device within the second preset time, increasing the possibility of scanning missed RFID tags.

[0081] In one embodiment, the generating of a specified scanning instruction according to the missed RFID tags and sending the instruction to the scanning device to scan the missed RFID tags separately includes:

[0082] For each RFID tag that is missed, a designated scanning instruction for the RFID tag that is missed is generated;

[0083] Sending a designated scanning instruction of the missed RFID tag to a scanning device to scan the missed RFID tag separately;

[0084] It is determined whether the missed RFID tag is scanned by the scanning device. If so, the state of the missed RFID tag is changed to scanned, and the missed RFID tag is changed to a scanned RFID tag.

[0085] In this embodiment, if the missed RFID tag is not scanned by the scanning device, no operation is performed on the missed RFID tag.

[0086] In this embodiment, a separate scan is sent within the first preset time. In order to ensure enhanced scanning of missed RFID tags, a specified scanning instruction for the missed RFID tags is generated, so that only the missed RFID tags will send a return signal to the scanning device to be scanned by the scanning device.

[0087] In this embodiment, a single scan is performed only once, because within the first preset time, the movement of the manager in space will not change significantly, so the number of RFID tags that enter the range of the scanning device with the movement of the manager will not be large, and scanning and identification can be performed until the next first preset time. At this time, the scanned RFID tag stops the communication between the scanning device and the scanned RFID tag after receiving the time-limited sleep instruction, so there is a lot of idle time in the communication time slot of the scanning device at this time. If the scanning device still does not scan the missed RFID tag, there are two situations, one is that the missed RFID tag is damaged or the signal is so poor that it cannot be scanned, and the other is that the missed RFID tag has not entered the scanning range of the scanning device.

[0088] In this embodiment, the designated scanning instruction is different from the ordinary scanning instruction. It is a start instruction for the designated RFID tag. When the scanning device receives the designated scanning instruction, it sends a radio frequency signal to the designated RFID tag. Only the designated RFID tag will return a signal to the scanning device after receiving the radio frequency signal to be recognized by the scanning device. The designated RFID tag here refers to the RFID tag that is missed.

[0089] In one embodiment, the step of generating a designated scanning instruction according to the missed RFID tags and sending the instruction to the scanning device to scan the missed RFID tags separately further comprises:

[0090] S701, determining whether there are any RFID tags that are missed, and if so, changing the scanning frequency of the scanning device;

[0091] S702, generating a designated scanning instruction according to the missed RFID tags and sending the instruction to the scanning device to scan the missed RFID tags separately;

[0092] S703, repeat S701-S702 until all scanning frequencies of the scanning device have been changed once or there are no RFID tags that are missed.

[0093] In this embodiment, in the use scenario of fixed assets, an ultra-high frequency (UHF) RFID tag is generally used, and the operating frequency is generally between 860 MHz and 960 MHz. RFID tags in this frequency band can achieve a longer communication distance, fast data transmission, and multi-tag reading. The operating frequency is generally set in a standard to form several scanning frequencies of the scanning device. For example, the American standard is usually in the frequency range of 902-928 MHz, while the national standard uses a frequency of 920-925 MHz. A non-standard frequency range can also be generated according to actual conditions. Generally speaking, the national standard frequency is used for scanning by default. When there are still RFID tags that are missed after the missed RFID tags are scanned separately using the national standard, the scanning frequency of the scanning device can be changed, and the missed RFID tags can be scanned separately again.

[0094] In one embodiment, updating the usage information of the fixed asset corresponding to the RFID tag according to the scanning result of the scanning device includes:

[0095] Generate a first list based on all RFID tags scanned by the scanning devices;

[0096] Generate a second list based on all missed RFID tags;

[0097] For each RFID tag that is not scanned, determine whether the RFID tag that is not scanned appears in the first list. If so, remove the RFID tag that is not scanned from the second list, change the status of the RFID tag that is not scanned to scanned, and change the RFID tag that is not scanned to a scanned RFID tag.

[0098] Obtaining used RFID tags from an RFID tag usage database;

[0099] For each used RFID tag, determine whether the used RFID tag appears in the first list or the second list, and if not, record the used RFID tag as an invalid RFID tag;

[0100] For the scanned RFID tag, update the usage information of the fixed asset corresponding to the scanned RFID tag according to the usage record and the preset depreciation rules;

[0101] For the RFID tags that were not scanned, determine whether the fixed assets corresponding to the RFID tags that were not scanned have been disposed of based on the usage records. If so, update the usage information of the fixed assets corresponding to the RFID tags that were not scanned and delete the corresponding relationship between the usage information of the fixed assets and the RFID tags that were not scanned. If not, add the missing information to the usage information of the fixed assets corresponding to the RFID tags that were not scanned and generate an error troubleshooting application.

[0102] For invalid RFID tags, determine whether the fixed assets corresponding to the invalid RFID tags have been disposed of based on the usage records. If so, the usage information of the fixed assets corresponding to the invalid RFID tags will be updated and the correspondence between the usage information of the fixed assets and the invalid RFID tags will be deleted. If not, the missing information will be added to the usage information of the fixed assets corresponding to the invalid RFID tags, and an error troubleshooting application will be generated.

[0103] In this embodiment, since the missed RFID tags are determined within each first preset time, there may be such a situation that, for example, the mouse 1 is borrowed to another office, and the RFID tag corresponding to the mouse 1 is 0004. The RFID tag 0004 is determined as the missed RFID tag within a first preset time, and is scanned within a subsequent first preset time. At this time, according to the scanning result of the scanning device, the RFID tag 0004 needs to be determined as the scanned RFID tag rather than the missed RFID tag, and there is no need to generate an error elimination application.

[0104] In this embodiment, the RFID tag usage database refers to a database of RFID tags in use. There may be a part of RFID tags that are not used on fixed assets after purchase, and these RFID tags are not in the database. For example, the fixed assets corresponding to the RFID tags have been sold.

[0105] In this embodiment, an invalid RFID tag is an RFID tag that is not associated with an RFID tag, and the RFID tag is not scanned during the tag scanning process, so the RFID tag can only be obtained through the scanning result summary of the final scanning device.

[0106] In this embodiment, the usage record is a record of any changes in the fixed assets of the enterprise, such as changes in the user, changes in the location of use, fixed asset sales registration, fixed asset scrapping registration, etc. The preset depreciation rule is the method by which the enterprise estimates the fixed assets. If the RFID tag is scanned, it proves that the fixed asset corresponding to the RFID tag still exists. At this time, the usage information of the fixed asset corresponding to the scanned RFID tag is updated mainly to update the current valuation, accumulated depreciation rate and other usage information. If there is a change in the user or location of use, it will also be updated synchronously.

[0107] In this embodiment, disposal means that the fixed asset has been scrapped or sold, and the usage record will also record the corresponding information. Therefore, when the fixed asset is disposed of, there is no need to set the corresponding RFID tag, and the corresponding RFID tag cannot be scanned at this time, so there is a missed scan. This missed scan situation requires the cancellation of the correspondence between the usage information of the fixed asset and the missed RFID tag. After the disposal update, there is no need to update the usage information of the fixed asset. If the missed scan is not caused by the disposal of the fixed asset, then it is possible that the missed RFID tag is damaged. At this time, an error elimination application is generated, and the missed RFID tag and its corresponding fixed asset are manually checked. The same applies to invalid RFID tags.

[0108] In this embodiment, if updating the usage information of the fixed asset corresponding to the scanned RFID tag involves updating the information of the usage location, it may be necessary to re-perform the label establishment process for the RFID whose usage location has changed. For example, if mouse 1 moves from one office to another, the RFID tag corresponding to mouse 1 will not be scanned in the original office. The RFID tag will be regarded as a missed RFID tag and will not be corrected until the information is updated. If the label establishment process is repeated for the RFID tag, this situation can be avoided during the label scanning process.

[0109] like Figure 2As shown, in one embodiment, a fixed asset management device is provided, which may specifically include:

[0110] The tag establishment module is used to generate fixed asset usage information based on fixed asset purchase applications and fixed asset usage, and to match the fixed asset usage information with the RFID tag;

[0111] For each RFID tag, associating the RFID tag with nearby RFID tags;

[0112] The tag scanning module is used to send a common scanning instruction to the scanning device every first preset time and obtain the RFID tag scanned by the scanning device and the number of times the RFID tag is scanned;

[0113] Determine the missed RFID tags according to the scanned RFID tags and the RFID tags associated with them;

[0114] generating a time-limited sleep instruction according to the number of times the scanned RFID tag is scanned and sending the command to the scanned RFID tag to stop the communication between the scanning device and the scanned RFID tag;

[0115] Generate a specified scanning instruction according to the missed RFID tags and send it to the scanning device to scan the missed RFID tags separately;

[0116] The information updating module is used to update the usage information of the fixed assets corresponding to the RFID tags according to the scanning results of the scanning device.

[0117] In this embodiment, each module of the fixed asset management device is a modularization of the method part of the present invention. For the specific explanation of each module, please refer to the corresponding content of the method part of the present invention, and the embodiment of the present invention will not be repeated here.

[0119] The RFID tag is set on the fixed asset;

[0120] The scanning device is in communication with the RFID tag and is used to scan and identify the RFID tag;

[0121] The computer device is communicatively connected with the scanning device and is used to execute the steps of the above-mentioned fixed asset management method.

[0122] In this embodiment, the RFID tag is usually an ultra-high frequency electronic tag.
