In a first embodiment, the woodworking mode is a mode of driving fasteners into a wooden workpiece, and the woodworking mode includes different kinds of working conditions, wherein the different kinds of working conditions are working conditions in which different kinds of wooden workpieces are matched with different kinds of screws. For example, the screw is driven into the wooden workpiece, the carpenter mode is divided into a first working condition, a second working condition and an N working condition, and different working conditions correspond to the states that different types of screws are driven into different types of wooden workpieces, such as screws with different diameters and wooden workpieces with different materials, and respectively correspond to different working conditions. In one embodiment of the invention, parameters of corresponding working conditions are obtained through operation tests on wood workpieces with different screws and materials, classification is carried out through cluster analysis or big data analysis, parameter intervals are divided, screw types and corresponding workpiece wood workpiece types in the same parameter intervals are divided into the same working conditions, and first-class working conditions, second-class working conditions and N-class working conditions are correspondingly generated.

Taking current as an example, the first type of state data may be a current value of a motor when the intelligent electric tool is operated, and the corresponding second type of state data is a current slope value of the motor. The method comprises the steps of collecting current average values and current slope average values of an intelligent electric tool during N seconds before driving various screws into various wooden workpieces through testing, classifying the current average values and the current slope average values through a clustering analysis method, setting first-class working conditions, second-class working conditions and N-class working conditions, storing the corresponding current average values and the corresponding current slope average values of the first N seconds in a storage device, obtaining current slope values and current values of the first N seconds corresponding to the intelligent electric tool in actual operation, weighting the current slope values and the current values of the first N seconds to obtain the current slope average values and the current average values of the first N seconds, and calling parameter intervals corresponding to different stored working conditions to obtain working condition types corresponding to the screws and the wooden workpieces in actual operation. Optionally, the first N seconds is set to the first 0.5 seconds.
In one embodiment of the present invention, the corresponding current slope threshold/threshold intervals for bottoming out fasteners for different types of operating conditions of the intelligent power tool are detected multiple times prior to assembly of the intelligent power tool, and the threshold/threshold intervals are recorded in a storage device of the intelligent power tool. When the intelligent electric tool is actually used and acts on a fastener, the detection unit detects N seconds before the intelligent electric tool runs or a certain period of time is selected to obtain a current slope average value and a current average value, and the type of the working condition currently in use, namely a specific first type of working condition, a specific second type of working condition and a specific N type of working condition is obtained in a table look-up or data comparison mode. The detection unit continues to detect the current slope value of the intelligent electric tool, when the current slope value exceeds a current slope threshold value/threshold value interval corresponding to the current working condition, the screw is judged to be close to bottoming or screw bottoming, namely the operation on the screw is completed, the control component controls to enter a first operation program, the first operation program is corresponding to the first working condition, the operation state of the screw is judged to be close to bottoming or screw bottoming, and under the first operation program, the intelligent electric tool stops rotating, is slowed down, or is slowed down at a first speed. Referring to fig. 5, in the first state data trend in actual operation, the current working condition type is obtained by obtaining the first state data and/or the second state data of the a time period and by means of table lookup or calculation; the corresponding threshold value or threshold value interval is further obtained through the working condition type judged in the time period a in the time period b, the condition that the fastening piece is close to bottoming or the fastening piece bottoming is judged, and the intelligent electric tool is controlled to operate in a first operation program or a second operation program at the moment, for example, the first operation program can operate at a first constant speed or can operate at a continuous speed or intermittently speed; the second operation program may be operated at a second constant speed, or may be performed at a continuous deceleration speed or at intermittent deceleration.
In some embodiments of the invention, the corresponding threshold value may be set for only one characteristic value, such as the current slope; in other embodiments of the present invention, the corresponding thresholds may be set for the two characteristic values, such as the current and the current slope, respectively, based primarily on consideration of different specific conditions. It can be understood that, for classifying the working conditions of the intelligent electric tool, in addition to setting the woodworking mode by using the matching of the screw type and the wooden workpiece as the classification object, any first state data and/or second state data and the corresponding threshold value/threshold value interval when the output power, the output rotation speed, the initial pressing degree of the user and the like of the intelligent electric tool affect the final bottoming, and the principle is consistent with the above classification method, and will not be described in detail herein.
