Embodiment Construction

[0047] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0048] In order to describe the technical idea of ​​the present invention in detail, the batching process of a concrete mixing plant is taken as an example below to describe in detail. According to the problem analysis of the background technology, the present invention provides a method for adjusting the preset value of ingredients, in order to adjust the materials thrown each time to the preset value, such as figure 1 As shown, the specific steps include:

[0049] S100: Obtain the preset value G of the input material 1 (That is: 20KG of material is expected to be put into each shaking, and the specific value can be set according to actual needs) and the operator can use experience according t...

Abstract

The invention discloses a preset value adjusting method and system for ingredients. Later fall value L'' is updated according to a preset value G1, a previous fall value L, a current fall value L' and an actual value G2, the closure time of a precision weighing valve is fed back and adjusted to form closed-loop control, and the adjustment is repeated, so that the actual value G2 of the discharge quantity is equal to the preset value G1 and accurate ingredients are ensured. Further, the preset value adjusting method and system for ingredients are particularly suitable for a mixing plant ingredient control method and system, thus improving the ingredient accuracy in the precision weighing phase, improving the production efficiency and the quality and reducing the production cost.

Description

technical field [0001] The invention relates to the control field of mixing equipment, in particular to a method for adjusting a preset value of ingredients, a method for controlling ingredients of a mixing station and a system thereof. Background technique [0002] The accuracy of the batching process is related to the quality, cost and efficiency of the product. Taking the batching process in a concrete batching plant as an example, in order to improve the accuracy of the batching and ensure the quality of the concrete, its feeding equipment usually includes two valves for rough weighing and fine weighing, and then divides the batching process into two stages: rough weighing and fine weighing . Taking 2000KG of material as an example, usually the rough weighing valve is opened first, and 1800KG is fed, and then the fine weighing valve is used to make it shake 20KG each time, and a total of 200KG is fed in 10 shakes to complete the entire batching weighing process. In thi...
