Detailed Description

In order to better understand the scheme of the application, the following detailed description is provided for the application with the accompanying drawings and the detailed description.

It should be understood that the terms "first," "second," "third," and the like, are used for limiting the components, are used for distinguishing the components, and have no special meaning if not stated otherwise, and therefore, should not be construed as limiting the scope of the present application. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

For example, fig. 1 shows a flow chart of a control method. In the method, the target object is connected with the motor through the tension detection device, namely the motor drives the tension detection device to drive the target object to move. The tension detection device is used for detecting target tension. Illustratively, the tension detecting device may be a tension meter. In one example, the motor may be connected to a controller, which may control the motor.

As shown in fig. 1, the control method includes the following steps:

s101, acquiring a target speed of the motor driving the target object to move.

Specifically, in the process of driving the target object to move by the motor, the rotating speed of the motor shaft of the motor may be equivalent to the moving speed of the target object, so that the target speed of the target object can be obtained by knowing the rotating speed of the motor shaft of the motor.

S102, in the process that the motor drives the target object to move, the target tension of the motor on the target object is obtained.

Specifically, in the process of driving the target object to move by the motor, the tension force applied to the target object can be detected by the tension force detection device, and then the target tension force applied to the target object by the motor is obtained.

S103, when the target tension is larger than the upper limit value of the first preset range, or the target tension is smaller than the lower limit value of the first preset range, the target speed is adjusted until the target tension is within the first preset range.

Specifically, when the target tension is greater than the upper limit value of the first preset range, or the target tension is smaller than the lower limit value of the first preset range, the target speed is adjusted until the target tension is within the first preset range. Therefore, the moving speed of the target object driven by the motor is automatically adjusted, and the moving speed of the target object can be in an appropriate range.

In one example, when the target speed is greater than the upper limit value of the second preset range, or the target speed is less than the lower limit value of the second preset range, if the target tension is still not within the first preset range, the alarm information is output. Because target speed has been the biggest or minimum, but the target pulling force still does not reach standard this moment, consequently can output alarm information this moment to remind the staff to overhaul, avoid the occurence of failure. Illustratively, the alert information includes: one or more items of sound information, light information and image and text information.

In one example, control maintains the target speed constant when the target tension is within a first preset range. Thereby allowing the target to move at a stable speed.

In summary, the control method provided by the application can automatically adjust the moving speed of the motor-driven object according to the pulling force of the motor applied to the object in the moving process of the motor-driven object, so that the moving speed of the object can be in a proper range, the production efficiency is improved, and the production accidents are reduced.

and when the target speed is greater than the upper limit value of the second preset range or the target speed is less than the lower limit value of the second preset range, if the target tension is still not in the first preset range, outputting alarm information.
