施工机械机群通用现场/远程监控系统的研究

Research on general field/remote monitoring system of construction machinery groups

目前施工企业的工程机械机群大多来自于不同的厂商,设备的内置专用控制器数据接口大部分为私有,从而导致这些设备无法实现通用远程/现场监控.针对这一问题,提出了基于外置式PAC(Programmable Automation Controller)的通用B/C/S(Browser/Server,Client/Server)综合模式下的工程机械监控系统平台.PAC实时采集运动构件的惯性数据和设备中的数字/模拟量传感器信号,并完成数据传输功能.软件平台完成了现场监控和远程监控的系统架构,并实现了影响服务器端速度和成本的关键技术:断点续传技术、数据压缩与还原算法.系统在盾构机监控中进行了应用与验证.

Currently, construction machinery groups of construction enterprises, mostly from different vendors,data interfaces of build-in dedicated controller of a device mostly private, resulting in these devices can not achieve universal remote/site control. To solve this problem, a construction machinery monitoring system platform based on external PAC of generic B/C/S integrated mode is built. PAC capture real-time inertial data of motion parts and digital/analog sensor signal of devices, and complete the data transfer function. Software platform complete system architecture for site monitoring and remote monitoring, and implementation of key technologies which affect the speed and cost of the server.HTTP, data compression and restore algorithms. System has been used and verified in the shield machine monitoring system.
