One reason is that poor of technical level , most civil manufacturers ’ products are based on the imported electro - hydraulic proportional controller which is act as the core , as a result , the cost become higher and lost the advantage of lower cost
在我国由于起步晚,技术水平低,汽车起重机生产厂商往往需要从国外引进电液比例控制系统核心控制器,以提升自身产品的竞争力。
According actual situations , a system design pattern called “ double cpu share memory ” is adopted for such a kind of electro - hydraulic proportional controller . so in the third part , the concrete realization is presented to show the efficiency of the system design pattern , in the middle of which it emphatically give out the design of the hardware driving model
针对怎样实现汽车起重机电液比例控制系统核心控制器问题,即系统的设计问题,本文从整体上研究和比较了多种方案,最终选择了双处理器共享内存的体系结构模式,并且从硬件和软件上完成了核心控制器的详细设计。
This paper analyses the type , function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback . that is , basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination . , determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic , the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop , and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination
本论文分析了目前常用比例阀的类型、功能、特性，并针对其不足提出新的改进方案，即：以流量放大，电反馈两个原理为基础，通过对流量闭环控制及压力流量复合的计算分析、确定上最小控制压差及流量控制范围，确定主阀结构、功能特性研究等，提出了“流量? ?负载压力变化? ?位移修正”的控制原理和压力流量双闭环控制原理，并进一步论述了利用一个比例控制器和一个“电?机械转换器”就可完成独立的压力或流量控制功能以及流量压力复合控制功能。
Based on above two points , developing electro - hydraulic proportional controller of having independent intellectual property is now urgent to civil auto crane manufacturer . at the beginning , in this thesis , a serial of models about auto crane ’ s function , construction and action are provided after being carefully analyzed with the modeling tool uml ( united modeling language ) . using these models , we can easily get along with the design and realization of electro - hydraulic proportional controller
本文首先从研究汽车起重机的功能入手,以面向对象的观点和使用uml作为建模工具,透彻地分析了汽车起重机功能应该具有的结构、行为特性,经过分析得出的结构、行为方面的特性是作为汽车起重机功能的内部描述存在的、具有固定不变的特点,这些特性的描述是研究与设计汽车起重机电液比例控制系统所必需的基础工作。
