文档介绍：皮带配料秤单片机控制系统
摘要:在医药、化工、冶金、建材、饲料加工等行业广泛地需要皮带配料秤单片机控制器用于物料的自动配制。实现物料的自动配制控制,不仅节省了人力和物力,而且也提高了产品的质量,提高了生产效率,同时也可以实现现代化科学管理。本文在介绍一种物料皮带配料秤单片机控制器结构及工作原理的基础上,着重对该仪器的单片机控制系统的部分功能实现作了详尽描述,并且介绍了一种采用8031等芯片设计的皮带配料秤和系统误差自适应调节的方法。
物料皮带配料秤单片机控制器主要应用于多种物料的定量混合配制的控制。为了提高物料配制的精度及配料的效率,配料的过程需要实现智能化、自动化。我们研制的皮带配料秤单片机控制器正是为了此目的。皮带配料秤单片机控制器主要由智能变送器、单片机控制器、电机驱动电路等组成,主要工作原理是用压力传感器进行物料的重量测量,传感器把物料的重量转换成电信号,经变送器把信号送入单片机进行处理,再由单片机发出物料已秤足重量的信号去控制送料和卸料电机工作,同时单片机还可与PC机进行串联通信,实现微机集成控制。

Abstract:An intelligent controller for mixed materials has been applied in many areas Such as medicine,chemical industry,metallurgy,architecture,animal feed Production and so on. It is not only saving in finance and reducing the fatigue Strength of workers,but enhancing the quality of Products and raising the efficiency of production. Moreover,this equipment improved modem scientific management in many factories. Based on the introduction of the structure and the working principle of an intelligent controller for mixed materials,this thesis mainly described the function of the single puter controlling system. Furthermore,the thesis referred the design of a converting circuit of AD7705 and discussed a method to modify system errors automatically.
This intelligent mixed controller has mostly been applied to mix many materials. For improving the accuracy and increasing efficiency of mixed materials,the process needed realize intellectuality and automation. So we invented this mixed controller. It was consisted of an intelligent voltage transfer,a single-puter control center,and circuits for driving motors. Its principle was used sensors to measure the weight of materials. Then sensors converted the weight to electrical signal. Passing the transfer the signal processed by the sing-puter controlled the drivers of motors working.
Furthermore the single-puter could munication with puter for realizing integration control.
