摘要
针对DALI系统双线差分信号的通信方式,对于采用传统照明的场所进行升级改造存在再次布线的问题,提出了在不改变电力线的基础上,以电力线作为DALI系统的通信介质,使DALI系统与电力载波通信相兼容。然而,由于载波信号的高衰减特性,使DALI系统在电力线上的传输受到了限制。对此,通过研究泛洪路由控制策略,解决了通信距离的问题,实现了以电力线为传输介质的DALI照明系统。系统测试证明,路由组网灵活,系统性能稳定、可靠。
In view of two-wire differential signals communication mode of the DALI system, a project to solve re-wiring problems in upgrading traditional lighting has been put in place, in which power line is used as the media to make DALI system compatible with power line carrier communication, without adjusting power line. But transmission of DALI system in the power line is significantly limited by severe attenuation of carrier signal. In this regard,the flood control relay routing strategy is adopted to tackle the problem raised from communication distance and to achieve the DALI lighting system using power line as the transmission medium. Approved by systematic tests, the relay route network is flexible stable and reliable in system performance.
