针对采矿塌陷区上建现代大型单层厂房、温室急需进行监测的要求,采用基于CAN总线技术的检测系统方案,通过单片机系统完成沉降数据的采集,实现智能节点的设计。同时采用CAN总线技术,实现数据的实时可靠的传输。再将数据直接传给计算机,进行数据集中分析处理。通过VB制作的监控管理软件,实现温度的查询与实时显示。以唐山马家沟矿区波及区上建设的凤凰花卉温室大棚为对象进行的监测试验表明,该地区塌陷明显,7个月的沉陷达到了几十毫米,最大点可以达到83 mm。本系统改变了传统集散控制系统的检测方式,节省了人力物力,并可以实现实时可靠的检测。%According to the monitoring requirements of building modern large-scale monolayer workshop and greenhouse in the mining subsidence area,the detection scheme based on CAN technology is adopted to realize the design of intelligent node,through the MCU system to complete settlement data collection. At the same time,the real-time and reliable data trans-mission is realized by the technology of CAN bus. Then the data is directly transmitted to the computer for data analysis and processing. The monitoring and management software based on VB is used to query and display real-time temperature. Monito-ring test data in Fenghuang flower greenhouse of Tangshan Majiagou mining area shows that the area is subsided obviously. Sedimentation value reached dozens of millimeter in 7 months,and the maximum dedimentation value can reach 83mm. The system changes the traditional detection method of distributed control system,saves manpower and material resources,and reali-zes real-time and reliable detection.
