Steering gear system and method for accurately feeding back operating current and output torque in real time

Abstract

The invention discloses a steering gear system and a method for accurately feeding back an operating current and an output torque in real time. The system includes a steering gear and a computer client. The steering gear is used as a lower computer to receive the command of a host computer and to make an action, and to feed back the data packet to the host computer. The steering gear includes a main controller of the steering gear, a temperature sensor, a current detecting chip A, a current detecting chip B, a potentiometer, an internal servo of the steering gear and internal motor of the steering gear. The computer client is used as the host computer to send control commands to the lower computer and visually present the data of the lower computer. The steering gear system of the invention uses two current detecting chips to measure the actual operating current of the steering gear, and is integrated in the steering gear without additional devices. When using, it only needs to receivethe feedback data packet of the steering gear to read the data. It has the characteristics of accurate data, small footprint and simple development. In particular, it solves the difficult problem ofhow to obtain the accurate operating current of the steering gear and accurately control the output torque.

Description

technical field [0001] The invention belongs to the scientific field of sensor detection and control, and specifically relates to the application of current detection technology, including the detection of the operating current of the steering gear and the control of the torque of the steering gear. Background technique [0002] The steering gear is a position (angle) servo drive, suitable for those control systems that require constant changes in angle and can be maintained. Most of the steering gears currently on the market only have basic functions and are difficult to apply in some specific fields. For example: in the design of a robot, the designer not only needs the steering gear to have the function of a common steering gear, but also needs the steering gear to have real-time current feedback, output torque feedback and other functions. Experiments have proved that the operating current can most accurately reflect the torque state of the steering gear . Current dete...
