一种DALI自编址分组寻址设备

A DALI Self-addressed and Grouped Addressing Device

本文提出一种DALI自编址分组寻址设备,此寻址设备既满足DALI标准,又能读取旋转编码器中的数值(旋转编码器1:组地址信息,旋转编码器2:短地址信息)。这样现场工程师就不必现场编址及分组,通过读取编码器中的数值即可确定组归属及将输出依逻辑关系设定短地址;在已经连网的情况下,甚至可以远程导入场景数据,不必现场工程师系统调试和现场配置,可以大大提高系统工程的实施效率。当外部总线供电异常时,亦可切换成内部总线电源供电以实现独立系统控制,提高系统总线异常时的可靠性。

This article proposes a DALI self-addressing and grouped addressing device,which meets the DALI standard,and can read the values in the rotary encoder(rotary encoder 1:group address information,rotary encoder 2:short address information).In this way,on-site engineers do not need on-site addressing and grouping.By reading the values in the encoder,they can determine the group ownership and set the short address of the output according to the logical relationship.When the network is connected,it can even import the scene data remotely without the need for on-site engineer system debugging and on-site configuration,greatly improving the efficiency of system engineering implementation.When the external bus power supply is abnormal,it can also be switched to the internal bus power supply to realize independent system control and improve the reliability.
