摘要:隨著工業控制的不斷深入發展，企業需要控制現場設備并需要現場提供詳細的過程數據以及對這些數據進行統計即控制和管理一體化，以確保生產的可靠性，降低成本，提高產品的質量及經濟效益。管控一體化是以過程控制系統為基礎，通過過程控制等信息的處理、整合、存儲、發布，運用現代化企業管理模式建立企業，覆蓋生產管理與基礎自動化的綜合系統。

　　　基于組態和可編程控制器的自動送料裝車系統主要由PLC、工控計算機和組態軟件組成。控制流程主要分為汽車進站、操作員記錄車輛信息、汽車到達送料裝車點進行送料裝車、裝車完成后汽車離站、獲取送料裝車憑據。該系統利用PLC來實現送料的基本控制，利用組態王來實現對送料裝車整個過程的監控。不但實現了自動送料控制的要求，還增加了現場數據采集和管理功能。設計中用SCS-100t地磅秤對進出站車輛的重量及用ICS-30皮帶電子稱對單次送料重量等數據進行采集，通過組態報表的應用對數據進行存儲和整理。自動送料裝車控制充分利用計算機對送料過程進行集中監控，使用靈活，組態方便。

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.
