摘要
常规系统存在数据成功接收比值和监管准确率低、数据传输延时长的问题,为此提出基于物联网的智慧工地视频监管系统。硬件方面,采用远程监管层、中心控制层、工地感知层以及基础设备层组成系统硬件结构,通过工地物联网整合施工现场视频信息,将监控数据无线传输至工地云平台,由监管终端显示信息数据;软件方面,根据数据价值和访问频率计算数据优先级,将优先级高的视频信息移入缓存空间,优先搜索和传输缓存数据。以变电站工程为例,设置对比实验。结果表明,设计系统提高了数据成功接收比值和监管准确率,缩短了数据传输延时,监管系统更加稳定。
Conventional systems have the problems of low successful data reception ratio, low supervision accuracy, and long data transmission delay. For this reason, a smart construction site video supervision system based on the Internet of Things is proposed.In terms of hardware, the system hardware structure is composed of remote supervision layer, central control layer, construction site perception layer and basic equipment layer. The construction site video information is integrated through the construction site Internet of Things, and the monitoring data is wirelessly transmitted to the construction site cloud platform, and the information data is displayed by the supervision terminal. In terms of software, the data priority is calculated according to the data value and access frequency, the video information with high priority is moved into the cache space, and the cached data is searched and transmitted first. Taking the substation project as an example, a comparative experiment is set up. The results show that the designed system improves the ratio of successful data reception and the accuracy of supervision, shortens the delay of data transmission, and the supervision system is more stable and reliable.
