联锁装置必须在确保安全可靠性的同时兼顾经济性。随着微电子学的发展,应用微处理机方式的电子联锁装置正在被各国铁路采用。由于它高性能又经济以及具有容错技术的特点,所以有着广泛的发展前途。一、各国研究状况1.瑞典方式瑞典是从1975年开始研究,他们采用通用的小型计算机的电子联锁装置。这种计算机是 Interlocking devices must take into account economy while ensuring safety and reliability. With the development of microelectronics, the application of microprocessor-based electronic interlocking device is being adopted by all national railways. Because of its high performance and economy as well as the characteristics of fault-tolerant technology, it has a wide range of development prospects. First, the research status of various countries 1. Swedish way Sweden is from 1975 began to study, they use a common small computer electronic interlocking device. This computer is
