Abstract

The invention discloses a method for controlling the locking force of a locking device, which relates to the technical field of industrial automation. A controller is arranged, the controller comprises a direct current motor driver, a main control chip, a temperature sensor, an AD sampling chip, a power supply module, a Flash chip, an RS422 power supply serial port input end and a locking device connector, and further comprises a high and low temperature constant temperature box and a torque sensor which are used for measurement. The influence caused by the magnetic field change of the direct current motor of the locking mechanism and the resistance change of the transmission part can be overcome, the locking force of the locking mechanism can be ensured to be basically unchanged, and the locking state is more reliable. And the locking force can be configured through software, hardware does not need to be changed, and the control precision of the locking force of the locking mechanism is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, in particular to a method for controlling the locking force of a locking device. Background technique [0002] With the development of navigation technology in our country, single-axis and multi-axis inertial navigation equipment has been widely used in military and civilian fields. The locking device can provide functions such as reference zero position and position locking for single-axis and multi-axis navigation equipment, and is an important part of inertial navigation equipment. [0003] The traditional control method of the locking force of the locking device is to set the current value of the final locked state as a fixed value; from the force formula of the current-carrying conductor in the magnetic field: F=BIL, it can be known that the magnetic field strength B of the motor and the coil length L are fixed. value, when the current is fixed, the output torque of the motor ...
