A Logistics Status Real-time Tracking System Based on Wireless Sensor Network

Abstract

Abstract-The progress in the economic society has driven the rapid development of the logistics industry. In the face of increasingly enormous and complicated logistics systems, it is of great practical significance to study how to effectively control the logistics process, minimize the labour cost and provide real-time monitoring data for users. For this purpose, this paper designs an active logistics status tracking (ALST) system platform based on Wireless sensor network (WSN). This paper, by fully integrating the characteristics of WSN, designs the system architecture based on the design philosophy of active logistics status tracking method; it also constructs and realizes the hardware function modules such as wireless sensor node, vehicle gateway, user terminal and backend server etc., and adopts the finite-state machine (FSM)-based active tracking model to maintain the logistics object status; and then it carries out programming of wireless sensor node active state tracking in TinyOS2.x, and finally performs system test under normal operation. The active logistics status tracking system can be widely applied in the logistics industry, to optimize the logistics process, reduce losses and improve logistics operation efficiency.Keywords-wireless sensor network (WSN), active logistics status tracking (ALST), finite-state machine (FSM), tinyos.2 IntroductionWith the increasingly complex logistics system nowadays, it is of great significance to study how to effectively control the logistics process, save labour costs and provide real-time monitoring data for users [1][2]. In the traditional logistics tracking method, the centralized control and optimization methods were often applied, which could optimize the operation of logistics system to some degree, but cannot satisfy the monitoring demands of the rapidly changing logistics system due to its technical limitations [3][4]. Now, in terms of information acquisition and network deployment, the WSN has been freed from the limitations of infrastructures in the traditional network, and can be customized to the demands of logistics operation. Compared with the traditional technology, it can not only collect and transmit data, but also perceive the status information of things and surrounding environment with certain computing 58

Filtering Algorithm for Positioning Accuracy of the Logistics Tracking System Based on the 3D Virtual Warehousing Logistics Demonstration System

“…Another is that if the initial point is not at the exit, then the end point of the initial point can be considered as a constant TSP problem, namely, ST-PSP problem. e mathematical model of the typical TSP problem can be expressed by formula (2), and the best path…”

“…If the potential field ant colony algorithm is used to solve the typical TSP problem, all the path points can be regarded as group individuals and can be adaptive function selection formula (2). For TSP and ST-PSP problems, potential field ant colony algorithm can only obtain the best access order of global path points, not the path, which cannot meet the requirements of the mobile wheeled logistics tracking system.…”

“…e continuous development of China's economy is inseparable from the development and support of logistics enterprises. At the same time, as a reasonable comprehensive service form in industrialization, it occupies an important position in the current economic development [1,2]. e packaging, storage, transportation, inspection, processing, and even the packaging and distribution of goods before and after constitute the current logistics system [3,4].…”
