摘　　要：针对电梯故障频发的问题,将网络互动技术应用到电梯监测和报警中。建立了由电梯运行状态集和故障判断逻辑组成的电梯故障分类分级模型,明确了电梯不同的运行状态,并且规范了电梯故障判断的依据;根据该模型设计了以高速MCU为核心的电梯运行状况监测报警终端,该终端通过独立传感器采集信息,以获取了电梯运行速度、站层、方向及电梯内是否有人等信息;同时将基于H.264视频压缩编解码技术的网络音视频模块集成在系统中,以对电梯内进行视频监控,与电梯内人员进行语音交流;在多次试点运行中,该系统能够让控制中心通过互联网获得准确的电梯运行状态信息和清晰的电梯内实时图像,并可以与电梯内人员进行远程互动。运行结果表明,该系统使电梯的远程监管更加合理和高效。Aiming at solving the problem that elevators encounter failures frequently, Internet interaction was applied to the elevator monito- ring and alarm system. Classification model for failures of elevators was built, which consists of the running statuses of elevators and the breakdown diagnosis. The classification model clears different running statuses of elevators and definites the judgement standard of elevators＇ failures. Based on it, operational monitoring and alarm terminal with MCU at the core was developed. The running speed, floor, direction and passenger status were gotten through the method of stand-alone sensor information acquisition. Meanwhile, module of online audio and video based on H. 264 was integrated in the system, the functions of video surveillance of the elevators and voice communications with pas- sengers in the elevators were provided. During several pilots, the system can make the control center receive the accurate information of run- ning statuses of elevators, and the clear real-time images in elevators through the Internet. Also, the control center can remotely interact with passengers in the elevators. The results of the pilots show that, the system makes the remote monitoring of elevators more reasonable and ef- fective.
