Automatic calibration method of system time for exploder and device and standard time acquisition module

The invention discloses an automatic calibration method of system time for an exploder. The method comprises following steps: acquiring system time of the exploder; acquiring current standard time; determining whether system time of the exploder is the same as the current standard time; and calibrating system time of the exploder. A realization device of the method and a standard time acquisition module are disclosed. The method and the device acquire current standard time from a GPS or a BDS through the standard time acquisition module and calibrate the system time of the exploder with the standard time as the reference so that accuracy of the system time of the exploder is ensured. 本发明公开了种起爆器系统时间自动校准方法，包括以下步骤：获取起爆器的系统时间；获取当前的标准时间；判断起爆器的系统时间与当前标准时间是否致；对起爆器的系统时间进行校准。并且公开了该方法的实现装置，以及该装置的标准时间获取模块。该方法和装置通过标准时间获取模块从GPS或BDS获取当前的标准时间，并以标准时间为参考对起爆器的系统时间进行校准，确保起爆器系统时间的准确。
