description The invention discloses an initialization method for a daisy chain communication system and a command identification device. The initialization method comprises the following steps: identifying a signal sent by a master device through a slave device to obtain a ping command; a slave device is reset based on a ping command and enters a bypass mode, and meanwhile, the ping command is sent to a subordinate slave device; and each slave device receives initialization information sent by the master device in the bypass mode so as to carry out initialization. According to the initialization method for the daisy chain communication system and the command recognition device, all the devices are rapidly reset and enter the bypass mode by sending the ping command firstly, rapid transmission of initialization information is achieved, and the initialization time is shortened. When the system is restarted due to faults, the restarting process is also accelerated. Based on a quick wake-up function in a quick initialization
