基于GPRS和GPS的机车信号远程监测车载终端设计

摘要

机车信号的监测和管理是指挥列车正常运行和故障诊断的关键,随着GPRS和GPS技术的不断成熟,机车信号远程监测系统得到应用.其中,远程监测车载终端是系统重要组成设备,本文以嵌入式工控机为控制核心,利用GPRS和GPS技术,提出一种机车信号远程监测车载终端设计方案,该方案具有结构简单、运行稳定可靠的特点,试验结果验证方案具有可行性.%The monitoring and management of locomotive signal is the key to the normal running and fault diagnosis of train. With GPRS and GPS technology matures, the locomotive signal remote monitoring system has been applied. The remote monitoring vehicle terminal is an important equipment. System based on embedded industrial computer as control core, using GPRS and GPS technology, puts forward a kind of locomotive signal remote monitoring vehicle terminal design scheme. This scheme has the characteristics of simple structure and stable operation. The test results show scheme is feasible.
