As shown in fig. 1, the embodiment of the present application discloses a method for controlling an electric screwdriver, which can implement the following steps:
101. and acquiring the initial voltage of the electric screwdriver when the electric screwdriver is powered on.
When the electric screwdriver is powered on, the Hall voltage output by the Hall sensor is obtained, and the voltage at the moment is used as the initial voltage. Since the assembly of each screwdriver is not exactly the same, the initial voltage is slightly different, typically around 2V, for example: 1.9V, 2V or 2.1V.
102. And acquiring the working voltage of the electric screwdriver in real time when the electric screwdriver works.

or, when the floating voltage is firstly reduced, an enabling signal and an electronic brake control signal are immediately generated.
In the embodiment of the application, the preset delay time is determined according to a fixed time form, or determined according to a dynamic adjustment form.

In another embodiment of the present application, the dynamically adjusting the preset delay time may implement the following steps:
acquiring historical working condition data and historical operating data of the electric screwdriver;
acquiring a plurality of corresponding historical difference time and historical duration time according to the historical operating data; the historical difference time is the time difference between the floating voltage reaching a preset threshold value for the first time and reaching a peak value in the historical operation process; the historical duration is the time difference between the time when the floating voltage reaches the peak value and the time when the floating voltage drops for the first time in the historical operation process;

In the embodiment of the present application, the peak value of the floating voltage may be about 0.5V, and the duration of the peak value may be about 50 ms. For example, under the same or similar operating conditions, the obtained estimated difference time is 15ms, the estimated duration time is 50ms, and the preset proportion is set to be 50%, when the floating voltage is greater than 0.2V, the delay time is 15+ (50/2) =40ms, that is, in the middle section after the floating voltage reaches the peak value, the enable signal and the electronic brake control signal are generated.

The braking duty cycle of the electronic brake refers to the time interval between each braking time and each two times of braking, in this embodiment of the present application, the braking time may be 5ms, and the initial braking duty cycle is generally 50%. For example, a braking time of 5ms and an operating time of 5ms are set, and the braking duty ratio is 50% at this time.
