直到最近，通信和控制系统都是由不同的团队设计、安装和接线的，通常没有共同的协调，使用不同的控制中心和接线方式。随着基于计算机的系统的到来和越来越多的集成和接口之间的连接，建筑师和工程师需要同时考虑最初的需求和未来的扩展和变化，在广泛的系统中，不仅包括传统的电信和环境控制，而且还包括新的技术，它们连接火灾报警和安全系统，能源和设施管理、电子邮件和卫星通信在主机系统中结合在一起，主机系统利用公共控制中心、垂直电线轴和水平配线，最终随机访问潜在的子系统和工作站。 本文探讨了目前在独立建筑和校园内的楼宇配电系统实践，并展望了未来的发展和新技术。还简要讨论了楼宇自动化的经济方面，因为它们与新建和翻新建筑的类型和尺寸有关。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

Until quite recently, communication and control systems were designed, installed, and wired by separate teams, often without common coordination and using different control centers and wire-ways. With the coming of computer-based systems and increasing integration and interfacing between them, architects and engineers need to consider both initial requirements and future expansion and changes in a wide range of systems that may include, not only conventional telecommunications and environmental controls, but also new technologies that interface fire alarm and security systems, energy and facilities management, electronic mail and satellite communication together in host systems that utilize common control centers, vertical wire shafts, and horizontal distribution wiring with eventual random access to prospective subsystems and work stations.This paper examines current practices in Premises Distribution Systems in individual buildings and on campuses and looks forward to future development and new technologles. The economic aspects of building automation are also discussed briefly as they relate to types and sizes of new and retrofit buildings.Units: Dual
