Abstract
With the development of Internet of Things (IoT) technology, especially the promotion of perception layer radio frequency identification (RFID) technology and wireless sensor network (WSN), a new way of thinking is provided for asset management. Applying both to the management technology of assets is an effective way to achieve intelligent asset management. This paper proposes an intelligent network applied to an asset management system based on WSN and RFID technologies. The whole intelligent asset management is divided into four layers according to the functional structure. From the top layer downward, the layers are the management and dispatch center, communication network, intelligent gateway, and data collection layer in order. Meanwhile, the functions and hardware composition of each layer are described. The data acquisition butcher is the sensing terminal of the whole intelligent asset management network. Smart nodes are its key devices to collect RFID data and sensing data to realize the intelligent sensing capability of the assets. The paper uses the MSP430 control chip, MFRC522 RF read/write chip, CC2425 wireless communication chip, temperature sensor, data memory, and voltage regulator chip to design the smart nodes in the system and details the working principle of the smart nodes and the networking process of the system. The newly designed intelligent asset management network can be deployed independently in asset management or can be integrated into the technical design of existing asset management systems. The management scheduling also collects and manages the RFID and sensing information of the area through the data collection layer, which improves the intelligent construction of the assets.
Highlights
The corresponding work involved in asset management is tedious, and the process is relatively fixed
This paper carries out research work such as understanding and analyzing the fixed asset and equipment management technology existing in enterprises, using advanced object-oriented technical means to analyze and model the needs of asset management, applying Radiofrequency identification technology (RFID) technology to track and locate important equipment, and using smartphones as tools to manage asset information in a timely and convenient manner
This paper proposes a new intelligent asset management network, which mainly consists of a condition monitoring IED fusing wireless sensor network (WSN) nodes and RFID tags and a master IED fusing aggregation nodes and readers, and focuses on analyzing the data communication mode between the condition monitoring IED and the master IED
Summary
The corresponding work involved in asset management is tedious, and the process is relatively fixed. This paper carries out research work such as understanding and analyzing the fixed asset and equipment management technology existing in enterprises, using advanced object-oriented technical means to analyze and model the needs of asset management, applying RFID technology to track and locate important equipment, and using smartphones as tools to manage asset information in a timely and convenient manner. The choice of WSN and RFID technology program, using its technical advantages of real-time positioning monitoring of valuable fixed assets, can effectively prevent the loss of valuable assets and damage to the enterprise and improve the security of assets and equipment and efficiency of use. The second chapter analyzes the research status of various intelligent asset management systems and condition monitoring devices at home and abroad, explains the advantages of integrating RFID technology with WSN technology, summarizes the advantages and disadvantages of existing research results, and puts forward the research direction and objectives of this paper.
