引言CSS-842000KN电液伺服试验机于1985年研制成功。通过部局级鉴定,获得较好的评价。“控制中心”相当于整机的大脑,全部采用了数字逻辑电路,且逻辑复杂,动、静信息有机地交织在一起,给逻辑分析带来了一定的困难。因此,对“控制中心”几个关键的、不易被人们所掌握的部分逻辑进行了较细致的分析,力图说明逻辑设计的基本思想。一、直流电平R-S触发器直流电平1与直流电平2之间,既可以随状态参量的不同而自动转换,又可以手动转换。这一切都是由“控制中心”直流电平触发器在有关信号作用下实现的。为叙述方便,以“静态位移——动态位移”的转换过程为例予以说明。结合图形如下(见图1)。
Introduction CSS-842000KN electro-hydraulic servo testing machine was successfully developed in 1985. Through the ministerial level appraisal, get better evaluation. The “control center” is equivalent to the brain of the whole machine, and all the digital logic circuits are used, and the logic is complex. The dynamic and static information are intertwined organically, which brings some difficulties to the logic analysis. Therefore, it analyzes the key logic of the “control center” which is not easy to be mastered by some people and attempts to explain the basic idea of logic design. First, the DC level R-S trigger DC level 1 and DC level 2, both with the state parameters can be automatically converted, but also can be manually converted. All this is done by the “control center” DC-level trigger under the influence of the signal. To facilitate the narration, the “static displacement - dynamic displacement” conversion process as an example to illustrate. Combine the graph below (see Figure 1).
