Description

Technical Field

[0001] The utility model relates to a control circuit for controlling a magnetocardiograph patient examination bed based on a servo motor. Background Art

[0002] The magnetocardiograph places one set of coils closer to the detection source (cardiac magnetic field) and another set of coils farther from the detection source. If the same background noise source is farther from the gradiometer coil (far-field source), it is evenly distributed in the space around the gradiometer coil, there is no magnetic field change, and the gradiometer is insensitive to it. The magnetic field of the human body being measured is very close to the gradiometer coil (near-field source), and is unevenly distributed in the space around the gradiometer coil, and the magnetic field change can be measured. Since the person being examined needs to remove all magnetic items from his body, lie on the examination bed in a standard position and remain relaxed, all magnetic items, including metal, need to be removed during the debugging of the magnetocardiograph.

[0003] After searching, the patent: A detection bed for magnetocardiograph detection (CN202022935398.1), including a bed frame, a gear transmission assembly fixed on the bed frame, and a conveyor belt transmission assembly fixed on the gear transmission assembly, an X-axis moving frame is fixed on the first transmission block driven by the gear transmission assembly to translate on the X-axis, a Y-axis moving frame is fixed on the X-axis moving frame, and a Y-axis moving frame is fixed on the second transmission block driven by the conveyor belt transmission assembly to translate on the Y-axis, the X-axis moving frame is a hollow frame with an isosceles trapezoidal cross section, and the Y-axis moving frame located above the X-axis moving frame is a fixed frame with an inverted isosceles trapezoidal cross section. A groove for accommodating the top surface of the X-axis moving frame is provided on the bottom surface in the middle of the Y-axis moving frame, and the bed frame is fixed on the base, and the base is provided with electrical connection holes for electrically connecting and controlling the X-axis moving assembly and the Y-axis moving assembly. The above structure also uses a dual motor to work, but it is not controlled, resulting in a decrease in accuracy.

[0004] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create a new structure of the control circuit of the patient examination bed of the servo motor controlled magnetocardiograph, so as to make it more valuable for industrial use.
