Embodiment Construction
[0033] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] Such as figure 1 As shown, this example provides a dynamic weighing filtering method, including the following steps:
[0035] Step S1, performing continuous equal-period sampling on the weight of objects on the conveyor belt;
[0036] Step S2, filtering the sampling result of the weight of the object to obtain a filtered weight value;
[0037] Step S3, calculating the weight change slope according to the filtered weight value;
[0038] Step S4, judging the weighing state of the object according to the weight change slope;
[0039] Step S5, determine whether to use a low-pass filter for filtering according to the weighing state, and output the final weight result.
[0040]In step S1 described in this example, during the continuous equal-period sampling process of the weight of the object, the sampling cycle time is T s ...
