The invention discloses a large-tonnage crane remote monitoring system based on the Internet of Things, and belongs to the technical field of crane control, and the large-tonnage crane remote monitoring system specifically comprises the following steps: collecting the rotating speed of a motor of a crane during operation, and recording the weight of an object carried by the crane every time; noise generated when the crane works is collected, environment noise is filtered, and crane noise is obtained; the method comprises the following steps: dividing the weight of an object needing to be carried by a crane into a plurality of grades, respectively carrying out linear fitting on the change relation of the crane noise along with the rotating speed and the change relation of the crane noise along with the load under different grades, and calculating the fitting degree of the noise and the rotating speed and the fitting degree of the noise and the load after linear fitting; when the fitting degree of the noise and the load is high, the noise is reduced by adjusting the carrying time distribution of the load, and when the fitting degree of the noise and the rotating speed is high, the noise is reduced by reducing the rotating speed of a crane motor; according to the invention, the working noise of the crane is effectively controlled.
本发明公开了一种基于物联网的大吨位起重机远程监控系统,属于起重机控制技术领域,具体包括:采集起重机的电机运转时的转速,并记录下每次起重机所搬运物体的重量;对起重机工作时的噪音进行采集,并将环境噪音进行过滤,获得起重机噪音;将起重机所需搬运的物体的重量划分为若干个等级,分别对不同等级下起重机噪音随转速变化关系、起重机噪音随负载变化关系进行线性拟合,并计算线性拟合后噪音与转速的拟合度,以及噪音和负载的拟合度;在噪音与负载的拟合度较高时,通过调整负载的搬运时间分配降低噪音,在噪音与转速的拟合度较高时,通过降低起重机电机转速降低噪音;本发明实现了对起重机工作噪音的有效控制。
