Description

Technical Field

[0001] The present invention belongs to the technical field of asset equipment management, and particularly relates to a method and a system for inventorying and labeling asset equipment. Background Art

[0002] The management of asset equipment is one of the important tasks of most units. Since the management of asset equipment involves different responsible departments, asset equipment in different periods, the transfer of asset equipment between different departments and locations, and many issues such as the maintenance, replacement, addition, and scrapping of asset equipment, for most units, the management of asset equipment is a stubborn problem that is difficult to solve. Although many management methods have emerged, their practicability is insufficient, the operation process is cumbersome, the efficiency is low, and the management method of asset equipment needs to be improved urgently.

[0003] For example, for enterprises and institutions at all levels, the full-life cycle management of asset equipment is the basis for cost accounting, benefit analysis, procurement decision-making, etc. of enterprises and institutions at all levels. The full-life cycle management of asset equipment is to conduct refined management on a single asset equipment from project demonstration, bidding and procurement, acceptance and use, maintenance, to retirement and scrapping. It not only requires an asset ledger that matches the accounts and physical objects, but also requires the asset ledger information to be unique, accurate, and comprehensive.

[0004] The common links in the management of asset equipment ledgers mainly include equipment acceptance, inventory and ledger establishment, and verification and inventory. However, from the actual situation of the ledger management of each enterprise and institution at present, the following problems exist:

[0005] First, after the asset equipment is accepted, the equipment is only warehoused and unwarehoused, the ledger information is established, and the asset barcodes are printed; equipment acceptance includes many links such as equipment testing, accessory verification, use training, and data collection; and usually the asset equipment has been put into actual use during the acceptance process; at the same time, restricted by factors such as batch procurement and distribution, irregular equipment flow, use environment limitations, and infection control and disinfection, the pasting work of asset labels lags seriously, and there are problems of missing pasting and wrong pasting.

[0006] Second, inventory and ledger establishment generally refers to enterprises and institutions conducting a new census of asset equipment to establish ledgers. Usually, a full-department census is first carried out, manually registered to form an electronic form, barcodes are printed in batches after being entered into the system, and then the corresponding barcodes are pasted according to the original registration form. The workload is large, the accuracy is low, and there is a risk of missing pasting and wrong pasting. During the time window from the full-department census to the corresponding barcode pasting, the transfer of asset equipment may occur, further increasing the workload and reducing the accuracy.

[0007] Third, the verification and inventory work is usually carried out according to the annual plan. Generally, the ledger forms of each department are first printed, and then each item is inventoried and compared one by one. It is not only time-consuming and laborious, the accuracy of the inventory is low, but also closely related to the subjectivity of the inventory personnel. The verification and inventory work has low efficiency and low accuracy. Summary of the Invention

[0045] In some embodiments, as Figure 1 shown, the method for inventory labeling of asset equipment includes the steps of:

[0046] S1. Directly obtain the image information of the asset equipment at the deployment site of the asset equipment; generally, the asset equipment has uniqueness. In the whole life management process of the asset equipment, there may be transfers of the asset equipment in different departments and different locations, or there may be intermediate stages such as equipment maintenance. Therefore, directly obtaining its information at the specific deployment site of the asset equipment can ensure the authenticity and uniqueness of the obtained asset equipment;

[0047] S2. Process the image information of the asset equipment to form the unique coding information of the asset equipment; usually process the information of the asset equipment obtained on-site, which can directly form the unique coding information of the asset equipment, avoid missing or repeatedly obtaining the information of the asset equipment, and avoid problems such as missing, mislabeling, and duplicate labeling of the asset equipment in the follow-up, and avoid confusion in the management of the asset equipment; among them, the "coding" in the unique coding information uses a 5- to 6-digit short code, the first digit is a letter or a number, and from the second digit onwards, all are numbers; this short code is a unique value within the unit to which the asset equipment belongs.

[0048] S3. Print the label containing the unique coding information on-site and paste the label on the corresponding asset equipment. Usually, after forming the unique coding information of the asset equipment on-site, directly print the label on the equipment site and paste the label, which can quickly and efficiently complete the acquisition of equipment information and label pasting, ensure the uniqueness of the label pasted on the asset equipment, avoid re-pasting, mislabeling, and missing pasting, and paste the label accurately and efficiently, which is conducive to establishing a clear and accurate asset equipment ledger and subsequent intelligent management.

[0049] Some embodiments of the asset equipment inventory and labeling method further include the steps:

[0050] S4. Use the mobile terminal to scan the label of the asset equipment to obtain the unique coding information of the asset equipment carried by the label and conduct an inventory of the asset equipment. Usually, during the use and transfer process of the asset equipment with a label containing the unique coding information pasted on it, it is necessary to undergo regular inventory checks to determine the actual status of the asset equipment, and it is also necessary to repair and maintain the asset equipment with problems to make it return to the normal working state in a timely manner and play its normal efficiency; using the mobile terminal to scan the label of the asset equipment can quickly and efficiently obtain the unique coding information of the asset equipment, determine the identity of the asset equipment, and manage its status. For example, the asset equipment in the normal working state completes the regular inventory and verification operations, the asset equipment in the abnormal working state undergoes warranty and repair, and the asset equipment that meets the scrap conditions starts the scrap procedure in a timely manner to complete the full life cycle management of the asset equipment.

[0051] The asset equipment inventory and labeling method disclosed in some embodiments, in step S1, obtaining the information of the asset equipment includes obtaining the information of the affiliated department and the image information of the asset equipment. The image information includes the appearance and nameplate of the asset equipment. Generally, each type of asset equipment has its own specific appearance shape. On the one hand, it is convenient to determine the identity of the asset equipment, and on the other hand, it can also initially determine whether the status of the asset equipment is normal. Therefore, usually, it is necessary to obtain the image of the corresponding appearance shape of the asset equipment. For example, the appearance shape image includes its six views, three-dimensional views at different angles, etc.; at the same time, each type of asset equipment has its equipment nameplate, which records the basic information of the equipment, such as the equipment name, model information, manufacturer, factory date, basic technical parameters, etc.; usually, the identity of the asset equipment can be uniquely determined according to the appearance information and nameplate information of the asset equipment. Therefore, usually, including its appearance and nameplate in the obtained image information of the asset equipment can perform subsequent information processing to realize the intelligent management of the entire life cycle of the asset equipment;

[0052] The asset equipment inventory and labeling method disclosed in some embodiments, in step S2, processing the information of the asset equipment to form the unique coding information of the asset equipment includes:

[0053] S201. Identify the nameplate in the image information, obtain the text information contained in the nameplate, and extract the text features of the text information;

[0054] S202. Compare the extracted text features with the built-in nameplate feature library of the system, find the feature value with the highest similarity in the nameplate feature library, and extract the corresponding element value in the feature library; for the variable elements in the nameplate, such as the factory number, extract the position and character features of the variable element for secondary positioning and feature extraction;

[0055] S203. If the extracted text features are similar to the built-in nameplate feature library of the system, go to step S204;

[0056] Otherwise, manually analyze the recognition result, store the recognition result in the nameplate feature library, update the nameplate feature library, and then go to step S204;

[0057] S204. According to the recognition result, form the unique coding information of the asset equipment including the recognition result. Generally, the unique coding information of the asset equipment at least includes information such as "coding", "name", "model", "SN", "factory date", etc. The "coding" format in the unique coding information of the asset equipment adopts a 5-6 digit short code. The first digit is a letter or a number, and from the second digit onwards, all are numbers; this short code is a unique value within the affiliated unit of the asset equipment.

[0058] The asset equipment inventory and labeling method disclosed in some embodiments, in step S201, specifically including identifying the nameplate in the image information to obtain the text information contained in the nameplate:

[0059] S2011. Extract the single - element features included in the nameplate based on the identification library of standard features;

[0060] S2012. Query the catalog standard feature library in the nameplate to obtain the matching degree of each single - element feature;

[0061] S2013. Query each single - element feature based on the nameplate standard catalog feature library to obtain the text features included in the nameplate.

[0062] In the asset equipment inventory and labeling method disclosed in some embodiments, the "coding" in the unique coding information determined in step S2 adopts an easy - to - remember short - code method, with a total length of 5 - 6 digits. The first digit is a letter or a number, and starting from the second digit, all are numbers. Calculated according to the character length and character range of the short - code, when the format of the short - code is 5 - digit all - numbers, the capacity is 99999. If it is increased to 6 digits and the first character can be a character, the capacity can be increased to more than 3 million, which can meet the asset management requirements of most enterprises and institutions.

[0063] An asset equipment inventory and labeling system disclosed in some embodiments is used to implement the asset equipment inventory and labeling method. The system includes:

[0064] An information collection unit, configured to obtain the information of the asset equipment at the installation site of the asset equipment;

[0065] An information processing unit, configured to process the information of the asset equipment to form the unique coding information of the asset equipment;

[0066] A label printing unit, configured to print labels containing the unique coding information on - site;

[0067] A mobile power supply, used to provide power for the labeling system;

[0068] A wireless router, used to realize the wireless communication between the information collection unit and the information processing unit;

[0069] A mobile vehicle platform, used to install the information processing unit, the label printing unit, the mobile power supply, and the wireless router.

[0070] In the asset equipment inventory and labeling system disclosed in some embodiments, the information collection unit is a mobile terminal with an image collection function. For example, it can be a mobile terminal with a camera and photo - taking function, such as a smart phone. After the information collection unit collects image information at the equipment site, it transmits the image information to the information processing unit for information processing. Therefore, usually, the information collection unit and the information processing unit are set to communicate in a wireless or wired manner to transmit information at any time.

[0071] In some embodiments, the asset equipment inventory labeling system disclosed has an RFID label printer as the label printing unit.

[0072] In some embodiments, the asset equipment inventory labeling system disclosed has a mobile terminal with RFID label recognition function as the information collection unit.

[0073] In some embodiments, the asset equipment inventory labeling system disclosed has a server with an information processing system built-in as the information processing unit. Generally, the information processing system built into the server can process the information of the asset equipment obtained, form the unique coding information of the asset equipment, and perform intelligent management of the entire life cycle of the asset equipment, such as establishing an asset equipment ledger, identifying image information, identifying nameplate information, achieving rapid inventory, and conducting equipment warranty.

[0074] The following further exemplarily illustrates the technical details in combination with embodiments.

[0075] Embodiment 1

[0076] In Embodiment 1, an asset equipment inventory labeling system for enterprises and institutions is disclosed, and intelligent management of asset equipment inventory is realized by using this system.

[0077] Figure 2 Schematic diagram of the composition of the asset equipment inventory labeling system disclosed in Embodiment 1;

[0078] The asset equipment inventory labeling system disclosed in Embodiment 1 can perform intelligent management of asset equipment, collect image information of asset equipment, process graphic information and establish an equipment ledger. This system includes:

[0079] The photographing and collecting device is the information collection unit, configured to obtain the information of the asset equipment at the layout site of the asset equipment; the photographing and collecting device selects a conventional Android mobile terminal for convenient photographing and collecting of equipment photos. Through the built-in equipment inventory photographing and collecting APP program, the asset equipment pictures are quickly uploaded to the information processing unit through the WIFI service provided by the wireless router;

[0080] The high-performance workstation serves as the information processing unit, configured to process the information of the asset equipment to form the unique coding information of the asset equipment. For example, the high-performance workstation is loaded with a device nameplate OCR recognition subsystem and an inventory subsystem, which are used to process information and realize the intelligent management of asset equipment inventory and labeling. The high-performance workstation can be a high-performance computer installed with relevant software systems / tools, integrated with an inventory subsystem and a device nameplate recognition subsystem, and is the information processing center and the asset equipment management control core of the inventory and labeling system. The inventory subsystem is used to import the equipment list for inventory, collect the equipment information for inventory, and form an equipment inventory data packet. The device nameplate recognition subsystem is used to automatically recognize the information in the device nameplate picture, assist the inventory personnel in quickly filling in key information such as "equipment name", "specification model", "serial number", "manufacturer", "production date", "registration certificate number", etc., greatly improving the input efficiency of equipment information and avoiding errors in manual input.

[0081] The RFID barcode printer serves as the label printing unit, configured to print labels containing unique coding information on-site. Usually, for the convenience of the dynamic maintenance of the asset equipment of various enterprises and institutions and the facilitation of asset inventory work, enterprises and institutions tend to use RFID-based electronic tags to achieve informatization management. The RFID barcode printer is used to print flexible metal-resistant RFID device tags and is configured on a mobile trolley.

[0082] The mobile power supply provides power for the inventory and labeling system. The mobile power supply powers the equipment of the asset equipment inventory and labeling system, enabling the entire system to work continuously for more than 8 hours without relying on external power, solving the need for frequent movement in the case where asset equipment is scattered in many departments.

[0083] The wireless router is used to realize wireless communication between the information collection unit and the information processing unit. It also serves as the communication device of the asset equipment inventory and labeling system to establish a wireless communication connection with the outside of the system. The wireless router is used to provide an independent wireless network for the entire inventory system. Usually, the internal network WIFI of some enterprises and institutions (such as hospitals) is strictly controlled, and at the same time, the internal network WIFI does not cover all departments. Some departments, due to their special requirements (such as shielded rooms, confidential rooms), cannot set up wireless networks. Therefore, in order to ensure that the photo-taking collection terminal can achieve mobile photo-taking collection in a WIFI environment, by providing a wireless router to build an independent wireless network, information collection, information processing, label printing, and offline inventory can be carried out.

[0084] Mobile trolley, used to set up barcode printers, high-performance workstations, mobile power supplies, and wireless routers. The mobile trolley is the hardware mounting platform for the entire inventory labeling system, which mounts hardware devices such as workstations, mobile power supplies, and RFID printers. Considering the special requirements of certain environments (such as hospitals), medical-grade ultra-quiet, anti-slip, and anti-tangling casters can be further adopted, and a foot brake system is provided; the entire vehicle body of the mobile trolley is made of high-quality rust-proof metal materials such as aerospace aluminum alloy, SPCC, and stainless steel. The entire vehicle body surface is smooth and antibacterial-treated. The panel is made of high-gloss and high-brightness ABS antibacterial material, which can withstand wiping and disinfection with common hospital disinfectants such as alcohol, chlorhexidine, and Shikang.

[0085] Using the asset equipment inventory labeling system disclosed in Embodiment 1, the method for labeling asset equipment includes:

[0086] S1. The photo acquisition device acquires the image information of the asset equipment:

[0087] The photo acquisition device is a smartphone equipped with an Android system. The built-in photo-taking APP in it standardizes the picture information of the asset equipment to be acquired, realizing the rapid acquisition of the picture information of the asset equipment;

[0088] The photo-taking acquisition APP by default requires uploading three types of images of the asset equipment: front, side, and nameplate. Among them, the image containing the "nameplate" is an important identifier of the asset equipment, which centrally records the name, specification model, serial number (SN number), manufacturer, factory date, registration certificate number and other nameplate element information of the asset equipment; the panoramic photos of the front and side of the equipment also play an important role in identifying and classifying the asset equipment; in addition, the photo-taking acquisition APP can also upload some other picture information with application value or management value, such as other codes that have been pasted, original host accessories that are easily damaged or lost, etc.; the picture information of the asset equipment acquired by the mobile APP photo-taking is transmitted to the information processing unit for OCR recognition.

[0089] S2. The high-performance workstation processes the image information to form a unique equipment code for the asset equipment;

[0090] The function of the nameplate OCR recognition subsystem built in the high-performance workstation is to automatically extract the element information in the nameplate of the asset equipment, such as name, model..., establish or update the asset equipment ledger, and solve the problem of a large number of manual transcriptions of nameplates in equipment inventory;

[0091] The recognition process of the nameplate OCR recognition subsystem for the nameplate mainly includes "picture feature extraction" and "element feature recognition". Among them, picture feature extraction includes extracting text information in the nameplate picture, such as text, XY position, etc., through the built-in OCR recognition engine, and extracting the features of the text therein according to the feature algorithm; element feature recognition includes comparing the text features with the built-in nameplate feature library of the system, finding the feature value with the highest similarity in the feature library, and extracting the corresponding element value in the feature library. For the variable elements in the nameplate (for example, the "SN" of the nameplates of the same manufacturer and the same model is different), the position and character features of the element can be extracted for secondary positioning and extraction;

[0092] According to the asset equipment management requirements of enterprises and institutions, the equipment ledger needs to record detailed and accurate information, including "name", "model", "SN (product serial number)", "registration certificate number", "manufacturer", "production date", "usage period", etc. The above information is recorded on most of the asset equipment nameplates and can be used as the recognition elements of the asset equipment nameplate;

[0093] The equipment nameplates are printed by each manufacturer, and the nameplate styles of each manufacturer are different. The text descriptions and locations of each recognition element are different. For example, for "name", some are directly located at the top of the nameplate, and some are marked behind "product name"; for "specification model", some are marked as "model", and some are marked as "product model"; for "serial number", some are marked as "product number", and some are marked as "SN", etc. At the same time, due to problems such as shooting light and angle, the recognition results of each nameplate image are affected to varying degrees, making the accuracy of the recognized text of each equipment nameplate uncertain. Therefore, the recognition of equipment nameplates also needs to face a large number of uncertain factors;

[0094] According to the above situation, an identification algorithm based on feature learning is adopted to extract and analyze the elements of the nameplate image, specifically including:

[0095] S2011. Single-element feature learning of nameplate information, obtaining the text information contained in the nameplate, and extracting the text features of the text information;

[0096] Separate nameplate feature databases for information such as "name", "model", and "manufacturer" are established;

[0097] For example, for different representations of "model", two features can be established:

[0098] [Product model:] P50;

[0099] [Model:] BY-R20 type;

[0100] In the database, the establishment method of the feature data is:

[0101] [%ORG%][%STRING%][%FIELD%][%PREFIX%][%VALUE%][%SUF%]

[0102] Wherein:

[0103] [%ORG%] represents the manufacturer. The characteristics of the nameplate vary from manufacturer to manufacturer, and the manufacturer information needs to be recorded;

[0104] [%ROWSTR%] represents the string, the character line after the nameplate photo is recognized;

[0105] [%FIELD%] represents the field, such as "NAME", "TYPE";

[0106] [%VARIABLE%] represents whether it is a variable. If it is "SN", the value is TRUE;

[0107] [%PREFIX%] represents the prefix, such as "Name:", "Device Name:";

[0108] [%VALUE%] represents the characteristic value, such as "Emergency ventilator", "Infusion pump";

[0109] [%SUFFIX%] represents the suffix, such as: "Type";

[0110] In the process of recognizing the nameplate picture, the characteristics of nameplates of different manufacturers can be gradually established and continuously accumulated. After accumulating a certain number of characteristics of the character line [%ROWSTR%], through similarity analysis, the characteristic value [%VALUE%] of the element information contained in it can be accurately recognized;

[0111] S2012. Similarity analysis of single element in nameplate information

[0112] Based on the characteristic data obtained from the single element learning result of the nameplate, the Jaccard Index is used to perform similarity analysis of nameplate recognition. The formula is:

[0113]

[0114] The Jaccard coefficient is the number of elements in the intersection of A and B divided by the number of elements in the union of A and B. The more elements the two sets have in common, the more similar they are; where A is the characteristic [%ROWSTR%] to be recognized, and B is the characteristic value recorded in the characteristic data;

[0115] S2013. Extraction of the catalog standard characteristic library of nameplate information

[0116] For asset equipment of the same manufacturer and model, their nameplates have a certain degree of similarity. Based on this, the standard features of the equipment catalog nameplate can be established through the K-means algorithm:

[0117]

[0118] Where: X = {x 1 , x 2 ,... x n} is the input data set, C = {c 1 , c 2 ,... c n} is the output clustering center, and K is the number of clustering centers;

[0119] The extraction process includes:

[0120] (1) Select k data objects of the same manufacturer and model from the identified nameplate data X as the initial clustering centers;

[0121] (2) Calculate the distance d(x i to the clustering center ci for each data object, and assign the data object to the class with the closest distance; i , c i )

[0122] (3) Calculate the average value of all objects in each class as the new clustering center;

[0123] (4) Repeat steps S302 - S303 until the clustering centers no longer change or reach the maximum number of iterations and then stop;
