ABSTRACT
This thesis firstly introduces the working principle of AMB and its developing situation in industry. To meet the industrial demands, it has designed a new AMB magnetic field homogeneity testing instrument; this design gives the detailed explanation to the peculiarity and function of the Hall-sensor which plays an important role in the course of design. Install the Hall-sensor on the special mechanical trestle which uses integrated Hall-sensor to obtain the collection of the induction intensity signal in its revolving course. The microprocessor use STC89C516RD+ to handle and show the measuring result. Hall-sensor and amplifiers are linear element. Through measuring, the linear degree of the whole system is higher, and the measuring error may control in about survey maximum value 2%. The thesis makes the brief direction of software to the display of design in its final part.
