Precision detection method and device of working position apparatus

The invention relates to a precision detection method and device of a working position apparatus. The precision detection method of the working position apparatus comprises the steps of under the condition that a reference working position apparatus is fixed at a preset position, acquiring first measurement information of the reference working position apparatus relative to the preset position; acquiring second measurement information of a to-be-adjusted working position apparatus relative to the preset position under the condition that the to-be-adjusted working position apparatus is fixed at the preset position; determining error information of the to-be-adjusted working position apparatus according to the first measurement information and the second measurement information; judging whether the error information meets a preset threshold condition or not; and under the condition that the error information meets the threshold value condition, controlling a prompting device to prompt the warning information.
