摘要
为了实现导架爬升式工作平台的信息化升级和提高安全性,使用了传感网络技术,以Windows CE和PLC为处理单元,以GPRS DTU为通信模块,使用TCP协议连接云服务器,利用PHP和HTML5技术搭建远程导架爬升式工作平台以实现实时监控网络平台。该系统能够实现超高报警、超重报警、触底报警和倾斜报警等功能,利用优化的限幅平均滤波算法解决绝对值编码器受到脉冲干扰引起的误报警问题。云平台网页消息基于HTML5的Web Socket技术进行实时推送,实现了在线实时监控、历史数据查询和报警功能。测试结果表明,该系统能够长时间运行,实时性好,性价比高,能满足多种场合的实时监控需求。
In order to realize the information upgrade of mast-climbing working platform and ensure safety,a remote real-time monitoring network platform was designed based on PHP and HTML5.Windows CE and PLC were used as the processing units,a GPRS DTU was used as the communication module,and the TCP protocol was used to connect with the server.These were all based on sensor network technology.Ultra high alarm,overweight alarm,bottomed alarm and tilt alarm could be realized in this system.The optimized limiting average filtering algorithm was used to solve the false alarm problem which caused by the pulse interference in absolute encoder.The web messages could be transferred in real-time based on HTML5 Web Socket technology,thus online real-time monitoring,historical data query and alarm were realized.The test results showed that the system was able to run in a long time,and had a good real-time and high cost performances,which could meet the needs of real-time monitoring in a variety of occasions.
