Design and Application of Wireless Temperature Monitoring System for Diesel Locomotive in Reconditioning Field Based on ZigBee Network

摘要

This paper focuses on the temperature monitoring and management of diesel locomotive in railway reconditioning field. The wireless sensor network monitoring system is utilized to replace the original manual operation. The algorithm of falling error is designed to realize high precision real-time monitoring and management. Firstly, ZigBee wireless communication is adopted to monitor temperature. Realize the remote monitoring of data unattended. Secondly, a portable acquisition terminal with low power consumption was design. Then, the wireless data receiving terminal is connected to the TCP/IP converter. The received data is connected to local area network (LAN), the monitoring and warning upper computer is designed. And the falling error algorithm is added to realize temperature compensation, real-time display, monitoring and warning and data storage. At the same time, it can realize the mobile terminal data viewing and monitoring and early warning. The design of the system has been preliminarily tested in Qingdao locomotive depot and further verified the rationality and feasibility of the scheme.
