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.
Highlights
With 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]
Determine whether the object is loaded onto the wrong vehicle: Aroused by the vehicle gateway, the wireless sensor node communicates with vehicle gateway to acquire the vehicle information, and compares the acquired information with that obtained at the initialization stage, checks whether the information is consistent, and determines whether the logistics object is loaded onto the wrong vehicle
The results show that the active status tracking method can: 1. Effectively reduce the data traffic in the logistics system; 2
Summary
With 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]. 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 collect and transmit data, and perceive the status information of things and surrounding environment with certain computing. The author designs an active logistics status tracking (ALST) system by fully utilizing various advantages of the WSN technology
