摘要
大型建筑工程中的塔吊在作业时,因为距离较近容易发生碰撞产生事故,严重影响了相关工作人员的安全,当前还没有针对此问题的相关安全监控系统,为此,设计并实现了一种基于传感空间三维数据定位技术的塔吊防撞系统设计方法;通过在塔吊间隔性安装角度与方位传感器实时采集位置数据,数据被传输到系统上位机中的数据处理模块,上位机中核心处理器使用三维定位的方法对危险距离计算,设定合理的报警阀值,一旦测试距离小于阀值,即可报警达到防止碰撞的目的;实验采用在高度15~22m范围内的不同环境下的10个测试塔吊中对系统进行了测试,分别就传感器的数据采集误差与报警误差两个角度进行测量,实际的系统测试证明,塔吊防撞系统具有较高报警准确率高达99.3%,应用性能极好。
Large construction projects of tower crane in the job, because close prone to collision accident, serious affect the safety of the relevant staff, currently there is no relevant safety monitoring system for this problem. Therefore, designs and realizes a kind of 3 d data based on sensing space positioning technology of tower crane collision avoidance system design method, through the in the interval of tower crane installation Angle and azimuth sensor location data real time acquisition, data is transmitted to the system of the upper machine data processing module, PC core processor used in the three dimensional positioning method of dangerous distance calculation, setting reasonable alarm threshold, and once the test distance is less than the threshold, can alarm to achieve the purpose of preventing collision. Experiment u-- sing 15-22m height of 10 different environment within the scope of the test system was tested in the tower crane, respectively with sensor data acquisition error and alarm two Angle measurement, the actual system test proves that the tower crane collision avoidance system has high alarm accuracy as high as 99. 3~, application performance is wonderful.
