液体原料自动称重配料系统(软件设计)

摘 要

随着微电子技术的应用，市场上使用的传统称重配料系统已经满足不了人们的要求。为了改变传统称重系统在使用上存在的问题，在本设计中将智能化、人性化用在了称重配料的控制系统中。随着科学技术的不断发展，自动称重配料系统已经广泛应用于冶金、煤炭、化工、建材等行业中。

自动称重配料系统可以按照设定配比和流量控制各输入物料的瞬时流量，从而达到控制各种产品的质量和产量的目的，是实现生产过程自动化和智能化、企业的科学管理、安全稳定生产和节能降耗的重要技术手段。微机配料控制+系统在生产中的应用不仅可以提高配料质量和产量，也大大减轻了岗位工人的劳动强度，提高了生产效率。本系统主要由单片机来控制，测量物体重量部分由称重传感器及A/D转换器组成，加上显示单元，键盘设定值单元，具有功能多、性能价格比高、功耗低等优点。同时系统集响应速度快、测量准确、自动化程度高等特点于一身。

我们设计的称重配料系统以STC89C54单片机为主控芯片，外围附以称重电路、显示电路、报警电路、键盘电路等构成智能称重系统电路板，从而实现自动称重配料系统的各种控制功能。经调试证明设计所完成的自动称重配料可满足实际生产应用需要。

An automatic weighing - burden system of liquid raw materials (software design)

ABSTRACT

With the application of micro-electronics technology, tradition weighing - burden system used in market has been not satisfied with human requirements already. In order to make up for the traditional weighing system shortcoming, we improve the weighing - burden system with intelligence and automation. Along with the development of science and technology, Automatic batching and weighing system has been widely used in metallurgy, coal, chemicals, building material industry, etc.

Automatic batching and weighing system can be set according to the input ratio and flow control of material flow, thereby achieve control of product quality and yield of the objective is to realize the automatic production process, and intelligent, enterprise's scientific management, safe and stable production and energy consumption is the important technical means. Computer control system in the production of ingredients used not only can improve the yield and quality ingredients and greatly reduce the labor intensity, and post to improve production efficiency.

This system is mainly controlled by microcontroller, the part of measurement accomplish consist of weighing?sensor and A/D transformer. This apparatus have many characteristic such as having more function, consuming less energy, small and moving easily, low price, measuring precisely, rapid speed, high degr
