Data updating method and auxiliary system

A data updating method implemented by an auxiliary system including a master electronic device and a plurality of slave electronic devices, each slave electronic device belonging to one of a first device group and a second device group. The data updating method comprises the following steps: a main electronic device transmits target data to at least one slave electronic device of a first device group, so that each slave electronic device of the first device group obtains the target data and executes an updating processing program; one slave electronic device of the first device group transmits the target data to at least one slave electronic device of the second device group, so that each slave electronic device of the second device group obtains the target data and executes an update processing program. 一种由一辅助系统实施的数据更新方法，该辅助系统包含一主要电子装置及多个从属电子装置，每一从属电子装置属于一第一装置群组及一第二装置群组的其中一者。该数据更新方法包含：主要电子装置将一目标数据传送至第一装置群组的至少一个从属电子装置，以使第一装置群组的每一从属电子装置获得目标数据并执行更新处理程序；第一装置群组的其中一个从属电子装置将目标数据传送至第二装置群组的至少一个从属电子装置，以使第二装置群组的每一从属电子装
