Input adjustment assembly and solenoid magnetic field measurement experiment device including the same

Abstract

The embodiment of the invention provides an input adjustment assembly and a solenoid magnetic field measurement experiment device including the same. The input adjustment assembly comprises an adjustment knob, a photoelectric encoder, a micro-controller and a display screen. The adjustment knob is connected with the rotation shaft of the photoelectric encoder and is capable of driving the rotationshaft of the photoelectric encoder to synchronously rotate. The micro-controller is connected with the output end of the photoelectric encoder and used for acquiring information of rotation directions, rotation angles and rotation speed of the adjustment knob according to pulse signals generated by the photoelectric encoder, and carrying out adjustment on a corresponding input object through parsing and analysis of the micro-controller. Through the input adjustment assembly including the photoelectric encoder, full digitalization of the input adjustment is achieved, so the input adjustment isquite rapid and precise. According to the invention, by use of the input adjustment assembly, fault rate of the device in use is greatly reduced; the experiment operation processes are quite convenient and simple; and good use effects are achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power electronics, and more specifically, relate to an input adjustment component and a solenoid magnetic field measurement experimenter including the component. Background technique [0002] The Hall effect is a kind of electromagnetic effect. This phenomenon was discovered by American physicist E.H. Hall in 1879 when he was studying the conduction mechanism of metals. When the current passes through the conductor perpendicular to the external magnetic field, the carriers are deflected, and an additional electric field is generated perpendicular to the direction of the current and the magnetic field, thereby generating a potential difference at both ends of the conductor. This phenomenon is the Hall effect, and this potential difference is also called called the Hall potential difference. Many universities provide students with a better understanding of the Hall effect and a more i...

Problems solved by technology

However, because potentiometers are often used inside the adjustment knobs of traditional experimental instruments, problems such as poor contact and unstable data often occur in experiments, which seriously affect the accuracy and effect of experiments.
