Step S1, monitoring the weight G of the material in the weighing hopper under the condition that a blanking door of the proportioning bin is opened;

step S2, the time is set to be in the first preset time period t₀Variation G of weight of material in internal weighing hopper₀And a first predetermined threshold G₀' making a comparison; or, when the preset event is monitored, the duration time t of the preset event and the second preset time t are compared₀' making a comparison;

step S3, when the time is in the first preset time period t₀Variation G of weight of material in internal weighing hopper₀Greater than a first predetermined threshold G₀If' and no preset event is detected, returning to step S1; or when the time is in the first preset time period t₀Variation G of weight of material in internal weighing hopper₀Greater than a first predetermined threshold G₀In time, a preset event is monitored, and the duration time t of the preset event is less than a second preset time t₀' then, go back to step S1;

wherein the preset event is the change G of the weight of the material in the weighing hopper in unit time_nLess than a second predetermined threshold G_nThe event of' or;

step S4, when the time is in the first preset time period t₀Materials in the internal weighing hopperAmount of change in weight G₀Less than or equal to a first preset threshold G₀' then; or, when the preset event is monitored and the duration time t of the preset event exceeds a second preset time t₀When the materials are mixed, abnormal signals of the materials are output;

the embodiment of the invention is realized by setting the first preset time length t₀The variation G of the weight of the material in the weighing hopper₀And a first predetermined threshold G₀' make a comparison when less than a reasonable first preset threshold G₀The abnormal batching detection method can reduce the influence on the batching time of the material due to different parameters such as the formula, the formula amount and the like of the material, does not need to frequently adjust the normal batching time of the material, can continuously monitor the duration t of the preset event after the preset event occurs, and can continuously monitor the duration t of the preset event according to the duration t of the preset event and the second preset duration t₀The comparison of' judges whether to output the abnormal signal of batching, prevents to produce the wrong judgement because of the unloading speed is uneven, increases the accuracy that the batching was judged unusually, wholly improves the whole operating efficiency of batching system, and the monitoring mode is nimble, application scope is wide.
