A control system and method for mixing ratio of concrete raw materials

Abstract

The invention discloses a control system for a concrete raw material mixture ratio. Through the control system, the using amounts of all raw materials for a large-size concrete mixing building can be automatically controlled according to a test mixture ratio in a construction period, and thus the construction quality of concrete is improved. The control system comprises an aggregate using amount control module, a concrete water using amount control module, an ice adding amount control module, a sand using amount control module, a cement using amount control module, a coal ash using amount control module, an additive using amount control module and a master control room server. Real-time communication between the master control room server and the aggregate using amount control module, the concrete water using amount control module, the ice adding amount control module, the sand using amount control module, the cement using amount control module, the coal ash using amount control module and the additive using amount control module is conducted through networks respectively. The master control room server provides mixture ratio information for the modules according to earlier stage concrete property test results, and the using amounts of the raw materials are controlled intelligently in the concrete mixing process. The invention further discloses a control method.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, nuclear power engineering, and port engineering, and specifically relates to a control system and method for the ratio of concrete raw materials, which are mainly used for automatic control of the amount of each raw material in a large-volume concrete mixing building. Background technique [0002] The control of the mix ratio of concrete raw materials is the key link to ensure the quality of concrete construction and affect the cost of concrete production. [0003] Conventional mixing ratio raw material control technology is mainly controlled by material weighing system. It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing. Under normal circumstances, the mixing station below 20 cubic meters per hour adopts the stacking weighing method, that is, one scale is used for aggregate (sand, stone), one scale is used for ceme...

AI Technical Summary

Problems solved by technology

The above-mentioned weighing system measures each quantity independently, and is separated from the concrete mixing system. It cannot realize the automatic control of the amount of various raw materials of concrete, and it is not convenient for the system management and analysis of data, which affects the efficiency of mixing and management.
