Inter-equipment synchronization method and device

The invention provides an inter-equipment synchronization method and device, and the method comprises that: second equipment obtains a first clock calibration signal of first equipment, and the firstclock calibration signal is used for achieving the synchronization between the second equipment and the first equipment; the second equipment calibrates a local clock of the second equipment accordingto the count value corresponding to the first clock calibration signal in unit time; the second equipment performs delay compensation on the acquired first clock calibration signal according to the transmission delay and the calibrated local clock of the second equipment; and the second equipment sends the first clock calibration signal after delay compensation. According to the technical schemeof the embodiment of the invention, the synchronization between the equipment can be realized under the condition that the environment is limited. 本申请提供了一种设备间同步的方法及装置，该方法包括：第二设备获取第一设备的第一时钟校准信号，该第一时钟校准信号用于实现该第二设备和该第一设备之间的同步；该第二设
