摘　　要：现代工程机械设备的性能与复杂程度不断提高,传统的现场故障诊断手段和方法已无法满足工程机械故障诊断需求。提出一种基于GSM/GPRS技术的工程机械设备远程监测与故障诊断系统,介绍该系统的硬件结构包括车载终端和远程故障诊断中心的构成,以及监控与故障诊断系统软件结构模块原理,重点叙述系统采用的多线程技术、故障检测和诊断技术等关键技术。该系统结合网络通信、多传感器数据融合以及故障树诊断等先进技术,对工程机械设备运行状态进行远程监测分析和故障诊断,便于及时发现和排除设备故障,协助工程机械制造商为用户提供及时有效的售后服务,最大程度避免或缩短故障停机,为企业和用户带来巨大的经济效益。Performance and complexity of modern construction machinery are getting higher and higher so that conventional field failure diagnosing means and methods can not meet the failure diagnosis requirements of construction machinery. A GSM/GPRS-technology-based remote monitoring and failure diagnosing system of construction machinery is suggested. The system hardware consisting of on-board terminal and remote failure diagnosis center is described and the modular principle of software architecture is also explained. Some key techniques applied to the system, such as multiple route, failure test and diagnosis, are emphatically depicted. In association with network communication, multi-sensor data mixing, failure tree diagnosis and other advanced technologies, the system remotely monitors and analyzes equipment operating conditions and then presents failure diagnosis, which facilitates in-time finding and troubleshooting of equipment failures and help construction machinery manufacturers provide their customers with prompt and effective after-sale-service to avoid or shorten downtime to maximum extent. All these bring significant economical benefits to enterprises and their customers.
