It has fully analyzed the difficult problems, demands and the current situation of the hospital, sorted out many disadvantages of the original system, carried out research and demonstration on the characteristics, advantages and industrial applications of RFID technology, designed the implementation process of RFID contactless mobile fixed assets inventory management system in combination with the established system of the hospital, explored the methods and specific implementation steps to solve the difficult problems, Summarize the benefits brought to hospital fixed assets management by the construction of this system.

1. Introduction

With the development of smart hospital construction and the landing and application of 5g wireless network technology and Internet of things technology, according to the overall requirements of the state for ...
... the hospital informatization construction goals and progress specifications, the original fixed assets management methods of the hospital are increasingly unable to meet the requirements of management. In particular, with the continuous development of the hospital, the purchase of advanced technology and medical facilities to improve the competitiveness of the hospital has made the number of fixed assets of the hospital more and more large, and the asset inventory work more and more difficult.

Asset inventory is an indispensable and important link in financial management. It plays the role of checking the physical objects and books of assets, reflecting the real state of assets, verifying on-site and supervising asset management. According to the requirements of state-owned assets management, the hospital conducts a comprehensive inventory of fixed assets at least once a year. However, the traditional fixed assets management methods and inventory methods can no longer meet the needs of the daily management of fixed assets. It is urgent to implement the modern intelligent management of fixed assets to achieve the purpose of fine and standardized management.

2. Current situation of the hospital

In 2015, Tai'an Central Hospital cooperated with a company to carry out the construction of the comprehensive operation management platform project, including the logistics management system, fixed assets management system and human resources management system, which improved the hospital's resource management ability, standardized the management process and promoted the implementation of the hospital's refinement. However, with the development of smart hospitals, there are many disadvantages in the current fixed assets management system: ① there are many departments, many types and many quantities, and it is impossible to complete the batch inventory, which is time-consuming. ② In order to prevent cross infection, special departments such as operating room, intensive care unit, intensive care unit, etc. cannot enter at will during normal work, so it is difficult to check assets. ③ Low control efficiency and weak supervision. Due to the limitations of the bar code itself, the two-dimensional code is easy to be stained, can be copied, and needs to be accurately aligned. A large number of manual operations are still required to complete the management of the equipment. ④ In actual operation, equipment that prints duplicate or missing codes often appears for various reasons, which makes it difficult to find and locate, and requires a lot of time and manpower to check. ⑤ The tag function is backward, unable to realize the interconnection of things, unable to connect with the hospital data platform, and unable to access the equipment management related data for economic operation analysis.

Therefore, it is urgent to explore quick and effective intelligent asset management methods. It is very important for fixed asset management to introduce an intelligent mobile fixed asset inventory and traceability system based on the Internet of things, and realize the interconnection of the Internet of things by using the fixed asset barcode technology and RFID technology.

3. Basis and advantages of RFID contactless mobile fixed assets inventory management system

Definition of RFID Technology

RFID (radio frequency identification) is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention, and can work in various harsh environments. The basic working principle of RFID technology is that after the tag enters the magnetic field, it receives the RF signal sent by the interpreter, and sends the product information (passive tag, passive tag or passive tag) stored in the chip with the energy obtained by the induced current, or actively sends a signal of a certain frequency (active tag, active tag or active tag); The interpreter reads and decodes the information and sends it to the central information system for relevant data processing.

Advantages of RFID Technology

Easy to read, automatic identification of long-distance and large flow, no manual barcode brushing; Data reading is "contact free" and no light source is required.

Fast identification: once the electronic tag enters the identification place, the card reader can read the information in it instantly, and can process multiple electronic tags at the same time to realize batch identification.

It is difficult to forge and has strong security. The electronic tag number is unique and cannot be changed. It can also set password protection for the reading and writing of stored data.

Strong penetration and environmental resistance RFID can read labels through non-metallic materials such as mud, dirt, paint, oil, wood, cement, plastic, water and steam during identification, without direct contact with the carrier, and has strong penetration.

Long service life and wide application range the system uses passive RFID ultra-high frequency technology to realize non-contact, fast and convenient reading of fixed assets information without opening the cabinet and unpacking, thus realizing one-to-one rapid inventory and query of fixed assets, especially for the fixed assets that are not visible outside the line of sight, avoiding repeated inventory or wrong inventory, and improving the efficiency and quality of asset inventory.

RFID industry application and practice research status at present, radio frequency identification technology (RFID) is developing very rapidly at home and abroad. There are many kinds of software and hardware products related to RFID, which are widely used in transportation control management, commercial automation, industrial automation, identity identification, anti-counterfeiting, asset management, information statistics, security control and document tracking / library management. The key to the application and development of RFID system is the electronic tag. The technology of passive RFID is more mature and its application is more extensive. The electronic tag itself receives the microwave signal of the RFID reader(click here) to provide its own short-term power supply.

In foreign countries, many integrated circuit manufacturers are committed to developing smaller and cheaper RFID chips. Domestic integrated circuit manufacturers have also been able to develop their own and approach the international advanced level. The future development trend of RFID chips will be that the chip has a longer operating distance, faster reading and writing speed, and the cost will continue to decrease.

In the field of fixed asset management, RFID technology has been widely used. Hospitals with advanced information technology in China have paid attention to the application of RFID technology. Unlike traditional tag technology, RFID technology can be used as a bridge between fixed assets and information systems, and can effectively integrate fixed assets and information systems, so as to achieve the real-time synchronization and consistency of physical information and system information. In the medical field, RFID technology has been used for the tracking management of surgical equipment and disinfection supply, as well as the process management of medical equipment in and out of the warehouse, application, depreciation, inventory, maintenance and scrapping. The wireless radio frequency identification technology solves the problems that the hospital medical equipment cannot be acquired in real time, the medical equipment is scattered in different departments, and the mobile equipment management is difficult. In general, there are few cases of using RFID technology for hospital level asset inventory management. Therefore, in the face of the huge workload of the medical industry, it is urgent to explore and study new management methods, equip intelligent equipment, and use information means to solve the current problems of difficult inventory, high pressure, and chaotic management due to large assets.

4. Method discussion

The hospital mobile fixed assets inventory and tracing system is an important part of the construction of the hospital fixed assets management system, and its construction planning needs to pay attention to the overall planning and top-level design. Under the framework of the overall digital construction and fixed assets management of the hospital. The integration with the existing fixed assets management information system shall be fully considered in the planning, so as to ensure the data consistency in the later system construction.

Make full use of existing resources to develop and integrate the RFID mobile fixed assets inventory system based on the original fixed assets management system, using information technology, mobile technology, bar code technology and radio frequency identification (RFID) technology.

First of all, all the fixed assets of the hospital shall be comprehensively upgraded. The original tags shall be upgraded and the tags with RFID core and printable integration shall be updated. At the same time, the mobile UPS power supply, network transmission, mobile workstation, label printer, RFID card issuer, bar code gun, high-speed camera, etc. can be integrated through the mobile identification cart to realize the intelligent mobile cart inventory. During asset inventory, the mobile cart can be sent to the site for inventory, information improvement, labeling, RFID matching, etc. the mobile cart can improve the efficiency of label upgrading and inventory, and prevent asset identification problems caused by asset movement.

The integrated location tag with RFID chip can be printed and identified by floor or room to facilitate the automatic identification of the location information of the current area and the recording and analysis of asset location changes during RFID induction inventory of mobile equipment.

The step-by-step implementation of fixed assets construction involves a wide range of areas and follows the principle of unified planning and step-by-step implementation. Taking into account the overall planning of the hospital, capital investment, etc., and taking a step-by-step implementation plan according to the needs of different levels of management. First, focus on departments with great difficulty in inventory, such as operating room, monitoring room and other important departments; Secondly, focus on the departments with more assets, such as laboratory and pathology.

Identify the newly purchased assets. When the new fixed assets are accepted, the mobile identification vehicle can be pushed to the acceptance site for work, retrieve the contract information, take photos of the acceptance equipment, scan the code, print and make Internet of things labels, scan the manufacturer's relevant acceptance sheets and certificates, and print the standard acceptance report on the spot.

Special labels are used for endoscopes, surgical instruments and other special assets. Endoscopic assets need to be cleaned and disinfected regularly. Ordinary RFID tags(more info) are not applicable to such assets, and special fixed labels that can be cleaned and protected against corrosion are required to ensure the effectiveness of the labels in the process of large-scale cleaning and disinfection.

Fully connect with the financial and financial asset management systems to establish a standard data import format that can be connected with the financial reporting system. After the system enters and exits, the standard format can be automatically generated and imported for submission; Establish the connection with financial vouchers. The voucher information generated by the asset system, such as receipt, delivery, transfer and depreciation, can be automatically pushed to the financial system to avoid manual repetitive entry, improve multi department collaboration efficiency and reduce errors.

The construction of intelligent inventory function is to set the cycle and scope of this inventory on the system, download the asset data to the mobile inventory car system or PDA through the network, and conduct regional and batch induction inventory, accurately locate, clearly record and analyze the data, so as to improve the inventory efficiency. In the process of counting with mobile counting vehicle or PDA, the counting area can be obtained by inductive RFID geographical location tag or by manual selection. Confirm the counting area, and the asset data of this area will be presented on the system. After the inventory is started, the asset with RFID chip in this area will be sensed and the system will automatically mark the asset with the "checked" mark. If there are assets in the counting area that do not belong to this location, the system obtains the asset information through the sensing chip, and can automatically analyze the change of asset location. If the assets originally in the counting area are not sensed, it is necessary to confirm whether there are asset borrowing and movement. If there is an asset change, it will be processed after reaching the end point of asset movement; If not, check the label of the physical object and consider whether to replace it. If the physical object is not found, mark the temporary missing mark on the system. Under the condition that RFID asset tags are basically complete, all fixed assets within the management range have a unique tag. The asset inventory system reflects the existence of fixed assets by sensing the presence of RFID tags. During the inventory process, it constantly improves asset information and updates asset changes.

5. Effect of RFID contactless mobile fixed assets inventory management system

The whole process tracking of fixed assets uses two-dimensional bar codes and passive ultra high frequency (UHF) electronic labels to identify the media of fixed assets, so as to realize the whole process tracking of the life cycle and use status of fixed assets.

During the daily management of the identified assets, the most prominent feature of the two-dimensional barcode technology is one-to-one code scanning: it is convenient, fast and accurate, easy to track and trace, greatly improving the efficiency of the inventory work, and ensuring the correspondence between the information flow and the real logistics of the assets. Realize the synchronous operation of logistics, capital flow and information flow of multi department coordination, and achieve information sharing. At the same time, the bar code technology is used for fixed assets management, which effectively solves the problems of inconsistent accounts, cards and objects, unclear assets, unclear equipment, idle waste and asset loss in asset management, provides comprehensive, reliable and efficient dynamic data and decision-making basis for hospital asset management, realizes information, standardized and standardized management of asset management, and comprehensively improves the efficiency and management level of hospital financial management.

The intelligent mobile inventory adopts the inventory cart, uses the wireless network, introduces the electronic tag and service management system, establishes the inventory management combining offline and online modes, and can upload and download the asset data through the certified WiFi wireless LAN or Internet, so that the financial and asset management personnel can understand the fixed asset information at any time and anywhere. The mobile inventory cart can scan the RFID fixed asset tags in batch, and perform location The multi-dimensional integrated automatic batch operation of departments, assets, and inventors truly realizes the seamless link between the intelligent mobile terminal and the background management system.

Improve asset monitoring capability after the implementation of RFID contactless mobile fixed assets inventory management system, on the basis of the realization of IOT, the system is connected with his, LIS, PACS, integrated platform, etc., and the whole process is connected with the asset management data, which improves the asset monitoring capability and effectively extracts the equipment operation information, including installation, income, expenditure, use times, maintenance times, daily maintenance, etc, Fully grasp the use of equipment, conduct electronic fence early warning and anti-theft management for the identified assets, and provide real data support for equipment benefit analysis.

The real-time intelligent asset management system connects the financial and financial systems through the centralized management operation mode, including financial reporting, voucher interface, budget management interface, etc., and integrates the asset, financial and business management departments, aiming to establish a unified, effective and real-time intelligent asset management system.

In short, the implementation of RFID contactless mobile fixed assets inventory management system will comprehensively improve the efficiency and management level of hospital asset management, and provide comprehensive, reliable and efficient dynamic data and decision-making basis for hospital economic operation analysis. It has laid a good foundation for the construction of hospital intelligent management system.
