摘　　要：基于站间通信的小型智能程控交换机系统以单片机为核心,采用模拟空分交换网络,分散控制。系统软件用C51语言编程,各功能模块并行工作。系统4条中继线可与电子对抗系统站间通信网的上级指挥中心连接,也可入公用电话交换网。外挂16个分机作为站间通信网的中心站有线用户,配备15个分站作为小交换机的无线用户,实现来话自动转接、有线无线用户交换、通播、点播、呼叫转移、来话转移等功能。Microcomputer was used as core of minitype intelligent system for program control exchanger based on communication between stations, analog switching network and decentralized control mode was used in hardware. Modularization program was compiled with C51 language, function modules worked in parallel. 4 relay line of the system were linked to superior command center of communication network between stations, and linked to public phones witching network. 16 PABX connected are used as wire user and 15 wireless substation are used as wireless user of PABX to realize automatic switching of calling, wire-wireless-user switch, broadcast-call, order-call, call out transfer and calling transfer.
