摘要:随着工业控制的不断深入发展，企业需要控制现场设备并需要现场提供详细的过程数据以及对这些数据进行统计即控制和管理一体化，以确保生产的可靠性，降低成本，提高产品的质量及经济效益。管控一体化是以过程控制系统为基础，通过过程控制等信息的处理、整合、存储、发布，运用现代化企业管理模式建立企业，覆盖生产管理与基础自动化的综合系统。
基于组态和可编程控制器的自动送料装车系统主要由PLC、工控计算机和组态软件组成。控制流程主要分为汽车进站、操作员记录车辆信息、汽车到达送料装车点进行送料装车、装车完成后汽车离站、获取送料装车凭据。该系统利用PLC来实现送料的基本控制，利用组态王来实现对送料装车整个过程的监控。不但实现了自动送料控制的要求，还增加了现场数据采集和管理功能。设计中用SCS-100t地磅秤对进出站车辆的重量及用ICS-30皮带电子称对单次送料重量等数据进行采集，通过组态报表的应用对数据进行存储和整理。自动送料装车控制充分利用计算机对送料过程进行集中监控，使用灵活，组态方便。

ABSTRACT:Along with the development of industrial control, enterprises need to control field devices and the need to provide detailed data on site and process these data statistics that is integrated control and management, to ensure that the production reliability, reduce the cost, improve the quality and the economic benefits of the product. The integration of management and control in production process control system as the foundation, through to the process control, information processing, optimization, storage, release, use the production and modern enterprise management model to establish a comprehensive system covering the enterprise production management and automation.
Automatic feed loading system mainly consists of PLC, industrial control computer and configuration software configuration and based on programmable controller. Control flow is mainly divided into auto stop, the operator records the vehicle information, vehicle reaches the feeding and loading point for feeding and loading, loading is completed car leaves, obtain feed loading credentials. The system uses PLC to achieve the basic control feeding, to realize the monitoring of the entire process of feeding and loading using configuration king. Not only has realized the automatic feed control requirements, but also increase the field data collection and management functions. To stand out the weight of the vehicle and electronic ICS-30 belt that collects a single feed weight data with SCS-100t electronic scale design, through the application of configuration forms for data storage and sorting. Automatic feed loading control makes full use of computer monitoring, for the feeding process of flexible use and convenient configuration.
