工业过程控制专家系统壳体构造

论计了专家系统壳体的构造，所叙述的壳体是一个用以构造和执行实时志家系统的多任系统。该专家系统壳体构造有三个并发进程和一个动态知识库构成。三个并发进程是：知识推理（Ｉｎｆ－Ｅｎｇ），键盘管理（ＫＢＤ）和控制器管理（ＡＣ１３２）．Ｉｎｆ－Ｅｎｇ任务能够由知识库中的当前知识导出新的知识。其控制结构是向前和混合拉链，单调深度俦查找。ＫＢＤ和ＡＣ１３２分别管理键盘输入和计算机工业控制器之间的通信，前者负责接

Structureof the expert system shell in the industrial process control

The structure of the expert system shell was discussed. This shell is a multfunctions system to form and perform the current expert system, which has three coexist proceedings and one dynamic engineering base. Three coexist proceedings are: inference by engineering (infEng), keyboard detector (KBD) and controller detector (AC132). IngEng can conduct new knowledge from current intellectuals in the engineering base. Its control structure is a forward zipper with preferential seek for monotonous depth. KBD and AC132 proceedings manage the keyboard input and the communications between computer and industrial controller respectively. The former is responsible to receive and verify the commands from keyboard and the latter manages the parallel transmission from computer to controller. The system has adaptability, friend interface with users, being convenient to use and low cost.
