Busbar system

The invention provides a busbar system. The plurality of slave elements are electrically connected to the master control element through a busbar. Each subordinate element is provided with a warning holding pin. The warning handshake pins of the subordinate elements are electrically connected together through a warning handshake control line. In a first stage of a first slave element corresponding to the slave elements in a plurality of stages of each distribution period of a distribution stage, the first slave element controls the warning handshake control line to be at a second voltage level through the warning handshake pin. And in the stages except the first stage in each distribution period, the first slave element controls the warning handshake control line to communicate with other slave elements through the warning handshake pin. According to the invention, the scheduling efficiency and elasticity of the busbar system can be improved. 本发明提供一种汇流排系统。多个从属元件通过一汇流排电连接于主控元件。每一从属元件具有一警示交握接脚。所述从属元件的所述警示交握接脚通过
