Title:
金属板重量測定システムにおける金属板計量値の異常検出方法
Document Type and Number:
Japanese Patent JP6865924
Kind Code:
B2
Abstract:
To provide an abnormality detection system of a metal plate measured value, which is, when the same weight value is consecutively generated, capable of detecting it as weighing abnormality.SOLUTION: Provided is a method for detecting abnormality of pile measured values in a carrying-out facility of metal plate piles, which comprises: conveyance means; pile lifting/lowering means; weighing means; and verification means. In this method, weight of each pile is measured twice when measuring two consecutive piles Gand Gin this sequence, so that pile weight data is obtained in the sequence of a measured pile weight value w, a re-measured pile weight value w, a measured pile weight value w, and a re-measured pile weight value w. Subsequently, a function of the verification means selects a combination of two kinds of measured pile weight values from the four kinds of measured pile weight values, obtains a difference between the selected two kinds of measured pile weight values, uses at least one kind of a differential value of the difference as a verification formula, in order to verify presence/absence of [abnormality of weighing means], and further stops the carrying-out facility in the case that abnormality is detected.SELECTED DRAWING: Figure 1
