【摘要】 随着人们生活水平的提高，高层建筑的数量越来越多，人们对于电梯的需求日益广泛，应运而生的电梯监控系统越来越受到广大厂商和用户的重视。而在互联网技术、通信技术高速发达的情况下，电梯监控系统已经不在局限于在固定的计算机监控中心通过PC机同现场总线相连来达到监控，远程监控和实时监控才能够保证对电梯信息和故障的更好获取。在此基础上，提出了电梯远程监控系统。电梯远程监控系统的功能是维保人员、生产厂商对运行在大型住宅区域的电梯进行远程监控，获取电梯的运行状态数据、故障信息，从而及时发现故障，分析和排除故障。本文根据电梯远程监控系统的实际需求，分析了通讯系统存在的问题，并结合了CAN总线技术和工业以太网技术，提出了通讯系统的整体方案。该方案主要需要实现CAN总线接入Internet的功能。本文以LPC2368微控制器为核心，与CAN通信模块和以太网控制模块一起构建了硬件系统。然后，对系统软件通信进行了详细设计。主要实现了底层的设备驱动、实现TCP/IP协议，从而建立一条完整的数据通路。根据数据通信存在的问题，采用不断发生心跳包的方式保持通信系统的可靠性，最终实现了电梯采集设备通过CAN总线接入Internet，互联网上的数据中心通过该系统实现对电梯采集设备的访问，达到双向通信的目的。更多还原

【Abstract】 With the improvement of people’s living standards and the increasing number of high-rise buildings, people’s demand for elevator is increasingly widespread and elevator monitoring system get more attention of manufacturers and users. As the high development of Internet and communication technology, elevator monitoring system is no longer limited to a fixed computer what is used as a monitoring center by using PC to connect with field bus. Remote and real-time monitoring systems are able to get better control of lifts. On this basis, this paper propose the elevator remote monitoring system, which function is getting running state data, fault information for maintenance personnel to discover failures, analyze and troubleshooting.According to the needs of the monitoring system and analyzing the exit problems, this paper proposed the overall design of the communication system combining with CAN bus technology and industrial Ethernet technology. The program aimed at implementing CAN bus connected to the Internet.This paper use LPC2368microcontroller as the core and design the CAN module and Ethernet module to build the hardware platform. Then conduct a detail design of the software communication, which include device driver, TCP/IP protocol, and build a complete data path. According to the data communication problem, use heartbeat packets to maintain the reliability of the communication system, so that the elevator acquisition devices can access to the Internet through the CAN bus, and Internet data center can achieve access to the elevator acquisition equipment through this system, Then achieve the purpose of the two-way communication.更多还原
