摘要:
本文研究了无触点集中-分散目标远动系统的逻辑结构.文中提出了采用简单的系统变结构来发送和接收信息的逻辑结构方式.对被控制点及一部分比较重要或变化比较频繁的被控制目标的信息,保留了循环传送,而对大部分变化比较慢的被控制目标则采用目标有变化时才传送信号的方式,这样就提高了系统的平均动作速度,同时也减小系统的失步概率.文中采用环节的复合利用及简化的逻辑单元线路来实现这种系统的逻辑结构.例如用两个分配器和一个简单的逻辑单元“和”线路组成了很简化的选点自动程序编码器,同时这两个分配器又复合利用兼组成目标信号接收矩阵式分配器等,因而可以使得这种系统同时又具有较高的极简化度.
Abstract:
In this paper the logical structure of contactless telemechanical system for distributed objects is discussed.A simple method of variable system structure for transmitting and receiving telemechanical information is adopted.The idea is that the information oc- curred in every controlled point(station)and the information of some of those objects, which frequently change their states,are transmitted continually and cyclically,while for other objects their information is transmitted only after any change in their states.Thus, the speed of operation will be increased,and also the error probability of system syn- chronization will be decreased.For the realization of the variable logical system struc- ture,several blocks are used repetitively.For example,two commutators and one sim- ple logical unit are used to construct a simple automatic sequential encoder,and at the same time,the two commutators are used also to operate as a matrix commutator for receiving telesignalling information etc.Therefore the system is comparatively simplified and attains a higher degree of“minimization”.
