一、概述由于电子计算技术、微电子技术和高可靠性系统构成技术的迅速发展,以计算机为主体的车站电子联锁装置在日本、欧美各国正在进入实用阶段,并在经济和安全性方面显示出了巨大的生命力。预计九十年代将进入推广阶段,这将大大加快信号设备全面更新换代的步伐。国外电子联锁装置的研究经历了艰难而漫长的发展过程,大体有三个阶段: 第一阶段,1957～1959年,试制了晶体管逻辑电路构成的电子联锁装置,但该方案没有解决故障安全技术。
I. Overview Due to the rapid development of electronic computing technology, microelectronics technology and high-reliability system composition technology, computer-based station electronic interlocking devices are entering practical phase in Japan, Europe and the United States and are displayed in economic and security aspects Out of great vitality. The nineties are expected to enter the promotion phase, which will greatly speed up the pace of comprehensive replacement of signal equipment. Foreign electronic interlocking device has experienced a difficult and long process of development, there are generally three stages: The first stage, 1957 ~ 1959, the trial of the transistor logic circuit consisting of electronic interlocking device, but the program did not solve the problem of fail-safe technology .
