An integrated demonstration experimental instrument for magnetic sensing sensor

Abstract

The invention discloses a comprehensive demonstration experiment instrument for magnetic sensitive sensors, and belongs to the field of instruments and meters. The invention in particular relates to a researching instruction demo instrument for revealing motor motion status simulation and digital open-loop detection and close-loop control properties through combining the magnet-sensitive sensor and the motor. The demo instrument consists of a casing, an angle sensor test system, a displacement test system, a motor close-loop test system, installation and test meters, a control keyboard, a front panel shifting between a switch and a wiring jack, and a wiring board with a single chip machine processing circuit. The instrument can give out a standard angle reading corresponding to rotation of the angle sensor shaft, accurately realize displacement measuring, and demonstrate how the motor rotation is converted to linear displacement. Through freely changing various spare parts of velocitysensors with different detection principles, the invention can be used for observing detection signal properties of various sensor parts and detection properties of gear velocity sensor products. Theinvention can be used for detecting properties of analogue output voltage signals proportional to the motor rotary speed, detecting charged current of the motor and researching the generated feedbackvoltage signal in close-loop power control.

Problems solved by technology

At present, in the physical experiment teaching of various colleges and universities at home and abroad, the basic experiments related to magnetic detection technology are almost blank, and there are only a few experiments related to magnetic sensors, but the experimental content is single, comprehensive and researchable. Strong, urgently need to be filled with basic experiments with new concepts that are novel in content and compatible with the development of contemporary science and technology
