Abstract
With the sensor, electronic technology, computer technology and the rise of weighing technology have developed rapidly, weighing device in digital, intelligent connection is a great improvement, weighing device research and development has entered a new stage. Weighing scales and other belt is emerging as a high-tech industries and countries around the world, the widespread concern, further introduction of new technology, the development of automatic weighing system to enhance the dynamic weighing accuracy, strengthen the network function is the focus of the development of all countries. China's weighing industry has begun to take shape, but the high-end products weighing technical backwardness, proactively develop our own intellectual property rights in high-grade products weighing on the development of China's weighing industry is of great significance. The issue was aimed at the electronic belt weigher’s automatic weighing system proceed. Belt weigher is installed on the conveyor belt in the appropriate place, the bulk of the material for automatic continuous, weighing a total of measurement apparatus. It is widely used: Bulk trade settlement, the production process of batching control and detection measures.
This paper described belt weigher computer batching system to MCS-51 microcontroller series for the next crew. To Belt Scales for the measurement equipment, SCM control belt weigher, to the entire system as the AVR Microcontroller PC for centralized management. The system of running low environmental requirements, the accuracy of stable, reliable, and easy to manage.
皮带秤是安装在皮带输送机的适当位置上，对散状物料自动地进行连续、累计称量的计量器具。它广泛应用于：散料贸易结算、生产工艺流程中的配料计量及检测控制。
采用双CPU结构，两个CPU之间通过串口进行通讯。两个CPU之间的这种弱联系，不但能提高控制的实时性，而且能有效的提高系统的可靠性。
本文所述皮带秤微机配料系统以MCS-51系列单片机为下位机，以电子皮带秤为计量设备，单片机控制皮带秤，整个系统以AVR单片机作为上位机进行集中管理。该系统对运行环境要求低，精度稳定，质量可靠，易于管理。
Dual CPU, the CPU between the two through the serial port communication. 2 CPU between the weak links will not only enhance control of the real-time, but can effectively improve the reliability of the system.

物料计量是工业生产和贸易流通中的重要环节。称重装置等衡量器具是不可缺少的计量工具。随着国民经济的发展和商品流通的扩大，过去沿用的机械杠杆秤已不能适应生产自动化和管理现代化的要求，衡器的技术水平需要不断提高。最近几十年来，伴随着传感器、电子技术和微机技术的崛起，称重技术得到了迅速发展，称重装置在数字化，智能化等方面有长足的进步。快速、准确、操作方便、消除人为误差、功能多样化等方面己成为现代称重技术的主要特点。称重装置不仅是提供重量数据的单体仪表，而ห้องสมุดไป่ตู้作为工业控制系统和商业管理系统的一个组成部分，推进了工业生产的自动化和管理的现代化。在物料输送过程中，各种连续输送大宗散状物料的皮带输送机，都广泛地采用了电子皮带秤，以作计量和控制之用，起到了缩短作业时间、改善操作条件、降低能源和材料的消耗、提高产品质量以及加强企业管理、改善经营等多方面的作用。电子皮带秤等称重装置的应用己遍及到国民经济各领域，取得了显著的经济效益。但是，我国在这方面的的产品少且功能不齐全，所以改善现有称重装置、开发研究功能齐全的自动称重系统是势在必行的
