The invention relates to a self-adaptive weighing method of a crane. The self-adaptive weighing method comprises the following steps or methods: signal parameter setting: hoisting a standard weight load with known weight by the crane, correspondingly acquiring weight sensing signals of the standard weight load in static and dynamic processes, carrying out signal conversion and self-adaptive low-pass filtering processing on the weight sensing signals, carrying out static calibration or dynamic setting on parameters of signal self-adaptive low-pass filtering by combining the weight of the standard weight load, and acquiring contrast data in the weighing process of the standard weight load to form a contrast queue; and weighing: hoisting a load to be weighed by the crane, acquiring a weight sensing signal of the load to be weighed, carrying out signal conversion and self-adaptive low-pass filtering processing on the weight sensing signal of the load to be weighed, acquiring data of the load to be weighed, comparing the data with the contrast queue to judge the motion state of the load to be weighed, and calculating the weighing value of the load to be weighed. The self-adaptive weighing method can ensure that the numerical deviation of the weighing value is within +/-3%.

    本发明涉及一种起重机自适应称重方法,包括以下步骤或方法:信号参数整定——起重机吊装已知重量的标重载荷,分别获取标重载荷在静态、动态过程中的重量传感信号,对重量传感信号进行信号变换与自适应低通滤波处理,结合标重载荷重量对信号自适应低通滤波的参数进行静态标定或动态整定,并获取标重载荷称重过程的对照数据形成对照队列;称重——起重机吊装待称重载荷,获取待称重载荷的重量传感信号,通过对待称重载荷的重量传感信号进行信号变换与自适应低通滤波处理,获取待称重载荷数据并与对照队列比较判断待称重载荷的运动状态,并计算待称重载荷的称重值。本发明能够保证称重值的数值偏差在±3%以内。
