Abstract

The invention discloses a batching control method and system of a concrete batching plant. The batching control method of the concrete batching plant comprises the following steps: sensing the first weight value of materials in a weighing hopper of the concrete batching plant when a first closing instruction is given, wherein the first closing instruction is used for controlling a rough weighing door or / and a fine weighing door of the concrete batching plant to close; sensing the second weight value of the materials in the weighing hopper of the concrete batching plant when the rough weighing door or / and the fine weighing door of the concrete batching plant is / are closed, and starting a fine weighing pulse batching manner; computing the material difference value between the second weight value and the first weight value; computing and updating a current first threshold according to the material difference value and a preset fine weighing pulse frequency or according to the first threshold and the preset fine weighing pulse frequency, wherein the first threshold is the weight threshold of materials giving the first closing instruction in the batching process of concrete. The batching control method and system of the concrete batching plant can be used for realizing automatic and precise batching.

Description

technical field [0001] The invention relates to the technical field of mixing, in particular to a batching control method and system for a concrete mixing plant. Background technique [0002] The aggregate batching process of the existing mixing station generally adopts the mode of rough weighing and fine weighing. That is to open the coarse weighing gate and the fine weighing gate to feed materials together. When the feed reaches the fine setting threshold, close the coarse weighing gate and the fine weighing gate, and use the fine weighing gate to feed the material in a pulsating way to control the accuracy of feeding. . The so-called precise pulse batching method refers to the use of pulse signals to control the switch of the precision gate. When the pulse signal is at a low level, the precision gate is closed, and when the pulse signal is at a high level, the precision gate is opened. The pulse waveform used to control the precise pulsation can be referred to as the pr...
