In terms of asset management research, great progress has been made both at home and abroad in recent years. Blockchain is a technical means for open sharing and traceability of data. From the perspective of technical integration, a fixed asset management system based on barcode and RFID technology combines QR code with Internet of Things technology and is designed based on QR code. Asset management system, and the introduction of Internet of Things technology to track and supervise asset status in real time to improve management quality and efficiency. Poudel et al. proposed a risk-based reliability-centered comprehensive asset management system framework that combines different categories of assets in a system to prioritize their maintenance.

Asset inventory is one of the most important links in the asset management process. Currently, some companies still perform asset inventory manually, and the inventory efficiency is extremely low. In order to solve the problem of slow inventory of fixed assets caused by manual registration of asset information, the system adopts an automated data collection technology, which combines handheld terminals PDA and RFID to combine the reading and writing of asset data with specific scenarios to improve asset management.

Product management and inventory efficiency.

RFID technology requires the use of barcodes, so companies need to pre-allocate fixed asset barcodes to ensure that each asset can be uniquely identified. There are two main ways to conduct visual asset inventory by combining PDA and RFID: The first method is suitable for inventory of specified assets. In this method, before the inventory, the asset information required for inventory needs to be imported from the backend management system into the handheld terminal and managed during the inventory. Personnel need to verify the imported asset information; the second method is suitable for free inventory. This method does not require entering asset information in advance. You can use a handheld terminal to scan the RFID tags of the assets required for inventory, and conduct visual inspection on the scanned assets through visual scenarios. confirm. The visual scene marks the location of asset registration, and the confirmation or transfer of physical assets is completed by confirming the actual location of the assets during the inventory process. After the inventory is completed, the inventory data will be uploaded to the asset management system.

property assessment. First, initialize the PDA. Since one PDA can be used by multiple managers, you need to log in using account and password authentication before taking inventory. After passing the certification, select the inventory method and check the asset information in sequence. If the verification information is consistent, save it and continue to scan and identify the RFID tag of the next asset; if the verification information does not match, modify the asset location and registration information through the visual scene, save it and continue to scan and identify the RFID tag of the next asset. In the visualization system of site assets, there is an interface connected to the RFID device to facilitate the import of asset data. After the inventory is completed, the inventory information can be imported into the asset management system with one click to facilitate the subsequent generation of relevant asset reports.
