Description

Technical Field

[0001] The invention relates to the technical field of magnetic field measurement, in particular to an automatic magnetic field measuring device. Background Art

[0002] At present, during the acceleration process of a 10MeV (mega-electron-volt) linear accelerator, due to the mutual repulsion between electrons, the focusing coil of the accelerating tube needs to provide a magnetic field parallel to the acceleration direction, so that the electrons can accelerate in a spiral along the acceleration direction to achieve a focusing effect. In order to ensure the focusing effect of the focusing coil under the set current, its magnetic field needs to be measured as accurately as possible before the equipment is installed. The traditional measurement method is to fix the Gaussian probe connected to the Gaussian meter cable in a plexiglass tube (superscript scale), and measure point by point (about 160-320 points) by manual pulling. This method requires two people to cooperate (one person pulls and the other records). A single measurement takes about 30 minutes, and maintaining the pulling action for a long time will cause fatigue to the personnel, which is very likely to cause missed measurements or repeated measurements. At the same time, due to the limitation of the manual pulling method, this method measures fewer points and cannot meet the high-precision measurement of more points. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Please refer to the attached Figure 1 , which is a schematic diagram of the structure of the automatic magnetic measuring device of an embodiment of the present invention. The automatic magnetic measuring device includes a control component and a magnetic measuring component, wherein the control component is arranged above the magnetic measuring component, the magnetic measuring component includes a Gaussian probe 9 and a probe fixing device 8 made of non-metallic material, the Gaussian probe 9 is fixedly connected to the probe fixing device 8, the control component includes a communication circuit, a motor controller 1, a motor structure, a winding shaft 5 and a Gaussian meter 7; wherein the communication circuit is electrically connected to the motor controller 1 and the Gaussian meter 7, the Gaussian meter 7 is also electrically connected to the Gaussian probe 9, the motor controller 1 is also electrically connected to the motor structure, the motor structure is a stepper motor 3 with a brake, the output shaft of the stepper motor is connected to the central axis of the winding shaft 5, a winding is arranged on the winding shaft 5, and the free end of the winding is connected to the Gaussian probe 9;

[0030] When the motor controller 1 receives a command to start forward motion through the communication circuit, the motor controller 1 controls the brake to release and controls the stepping motor to move forward, so as to drive the winding shaft 5 to rotate forward, and the forward rotating winding shaft 5 drives the free end of the winding to move downward at a uniform speed, so as to drive the magnetic measuring component to move downward at a uniform speed;

[0031] When the motor controller 1 receives a stop motion instruction through the communication circuit, the motor controller 1 controls the brake to tighten and controls the stepper motor to stop moving, and the brake stops the rotation of the winding shaft 5 to stop the movement of the winding and the magnetic measuring component;

[0032] When the motor controller 1 receives a command to start reverse motion through the communication circuit and the Gaussmeter 7 receives a command to start magnetic measurement through the communication circuit, the motor controller 1 controls the brake to release and controls the stepper motor to move in the reverse direction, so as to drive the winding shaft 5 to rotate in the reverse direction. The reversely rotating winding shaft 5 drives the free end of the winding to move upward at a uniform speed, so as to drive the magnetic measuring component to move upward at a uniform speed.

[0033] Specifically, the Gauss meter 7 and the Gauss probe 9 together form a magnetic field strength measuring instrument, wherein the Gauss probe 9 is used as a sensor and the Gauss meter 7 is used as an instrument. The Gauss probe 9 generates a Hall voltage due to the Hall effect in a magnetic field, and after measuring the Hall voltage, the magnitude of the magnetic induction intensity can be determined according to the Hall voltage formula and the known Hall coefficient.

[0034] Specifically, when the automatic magnetic measuring device of the embodiment of the present invention is used for magnetic measurement, the Gaussian probe 9 is first lowered at a uniform speed to a preset low position (corresponding to the preset number of positive rotations of the winding shaft 5) and then stopped, and then the Gaussian probe 9 is raised at a uniform speed to a preset high position (corresponding to the preset number of reverse rotations of the winding shaft 5) and then stopped. The Gaussian probe 9 measures the magnetic field of the focusing coil during the uniform lifting process, and the measurement data is obtained through the Gaussmeter 7. Before measuring the magnetic field, the measurement points of the focusing coil to be measured can also be set according to actual requirements to achieve the purpose of real-time automatic magnetic field strength measurement and meet the high-precision measurement requirements of more points. And because the automatic magnetic measuring device of the embodiment of the present invention realizes automated measurement, there will be no phenomenon of missed measurement or repeated measurement, and the measurement time can be greatly shortened.

[0035] Specifically, the automatic magnetic measuring device of the embodiment of the present invention changes the existing method of manually lifting the Gaussian probe 9 to measure the magnetic field strength point by point, and realizes the automatic, rapid and stable lifting of the electrically driven Gaussian probe 9 through the coordination of mechanical structure and electrical. In addition, the automatic magnetic measuring device selects a Gaussian meter 7 that can realize the communication function, and can read the magnetic field strength measurement value in real time through the background software, and can also perform data processing on the collected magnetic field strength measurement value, and automatically generate the measurement result after analysis or statistics.

[0036] Specifically, the automatic magnetic measurement device of the embodiment of the present invention changes the existing manual lifting method of magnetic measurement. Through the coordination of mechanical structure and electrical, it realizes the automatic, rapid and smooth lifting of the electrically driven Gaussian probe 9, so as to automatically measure the magnetic field strength of the focusing coil, which greatly saves manpower and has a high degree of automation.

[0037] Further, the probe fixing device 8 comprises an upper ring, a middle ring and a lower ring which are arranged in sequence from top to bottom; the outer surface of the upper ring, the outer surface of the middle ring and the outer surface of the lower ring are fixedly connected by at least one curved rod, the radius of the upper ring is equal to the radius of the lower ring, and the radius of the middle ring is greater than the radius of the upper ring;

[0038] An upper circular ring is arranged at the center of the upper ring, the upper circular ring is concentric with the upper ring, three support beams are arranged radially between the upper circular ring and the upper ring, and the angle between adjacent support beams is 120 degrees;

[0039] A middle circular ring is arranged at the center of the middle ring, the middle circular ring is concentric with the middle ring, three support beams are arranged radially between the middle circular ring and the middle ring, and the angle between adjacent support beams is 120 degrees;

[0040] A lower circular ring is arranged at the center of the lower ring, the lower circular ring is concentric with the lower ring, three support beams are radially arranged between the lower circular ring and the lower ring, and the angle between adjacent support beams is 120 degrees;

[0041] The center points of the upper ring, the middle ring and the lower ring are all located on the same straight line, and the Gaussian probe 9 passes through the center points of the upper ring, the middle ring and the lower ring respectively (equivalent to the center position where the Gaussian probe 9 is fixedly connected to the probe fixing device 8), and when the magnetic measuring component moves, the Gaussian probe 9 is always located on the central axis of the focusing coil to be measured.

[0042] Specifically, when the magnetic measuring component moves, the Gaussian probe 9 and the probe fixing device 8 always move synchronously. When the Gaussian probe 9 measures the magnetic field strength of the focusing coil to be measured, the structure of the probe fixing device 8 can help the Gaussian probe 9 to be evenly stressed, and is more conducive to always keeping the Gaussian probe 9 at the central axis position of the focusing coil, so that the magnetic field strength data measured by the automatic magnetic measuring device of the embodiment of the present invention is more accurate.

[0043] Furthermore, the probe fixing device 8 is a plexiglass probe fixing device.

[0044] Specifically, in the process of automatically raising the Gaussian probe 9 at a constant speed to measure the magnetic field, the probe fixing device 8 made of non-metallic material will not affect the magnetic field strength data measured by the Gaussian probe 9. Among them, organic glass material has good toughness, is not easy to be damaged and is relatively common. The use of the probe fixing device 8 made of organic glass can further improve the feasibility of the automatic magnetic measurement device of the embodiment of the present invention.

[0045] Furthermore, the control component also includes a wire pressing roller 6, which is arranged on the side of the winding shaft 5. The winding shaft 5 and the wire pressing roller 6 form a through hole, and the free end of the winding wire passes through the through hole to perform an upward uniform motion or a downward uniform motion.

[0046] Specifically, the wire pressing roller 6 can prevent the winding from slipping off the winding shaft 5 during movement, thereby ensuring the long-term stability and reliability of the magnetic measurement process. The winding can be made of Dyneema line, which is strong, has a large tensile value and strong flexibility, and is particularly suitable for suspending the Gaussian probe 9.

[0047] Furthermore, the communication circuit is a serial port converter 2, and the serial port converter 2 is an RS485 to USB interface.

[0048] Specifically, the RS485 to USB interface is a common type of adapter on the market. Through the RS485 to USB interface, the motor controller 1 and the gaussmeter 7 can be quickly connected to an external computer (generally computers are equipped with a USB interface), which is convenient for the computer to send control instructions to the motor controller 1 and the gaussmeter 7, and at the same time receive the magnetic field strength data collected by the gaussmeter 7 through the gauss probe 9, so as to facilitate the subsequent review and collation and analysis of the magnetic measurement data.

[0049] Furthermore, the control component also includes a battery pack 4, and the battery pack 4 is electrically connected to the motor structure.

[0050] Specifically, the battery pack 4 is used for power supply. The battery pack 4 can be a rechargeable battery pack 4, so that the automatic magnetism measuring device of the embodiment of the present invention can measure magnetism without external power supply. For example, the battery pack 4 is a 24V18650 type battery pack 4.

[0051] Furthermore, the output shaft of the stepper motor is gear-engaged with the central shaft of the winding shaft 5 .

[0052] Specifically, the gear meshing connection is a common connection method used by those skilled in the art, and the gear meshing connection method can further improve the feasibility of the automatic magnetic measurement device of the embodiment of the present invention. The stepper motor 3 with brake is a 42 stepper motor, and the brake is a 24V motor brake.

[0053] Furthermore, a shell is arranged outside the control component, and the shell is located above the magnetic measuring component.

[0054] Specifically, the housing protects the control component so as to further extend the service life of the control component.

[0055] Furthermore, the gaussmeter 7 is provided with a display screen, and the gaussmeter 7 and the gauss probe 9 are connected by a cable.

[0056] Specifically, the setting of the display screen makes it convenient for measurement personnel to check the measurement data of the magnetic field strength in real time.

[0057] Furthermore, the control component also includes a computer, and the computer is electrically connected to the motor controller 1 and the Gaussmeter 7 respectively through the communication circuit.

[0058] Specifically, the computer is used to send control signals to the motor controller 1 and the gaussmeter 7 , and is also used to receive magnetic measurement data sent by the gaussmeter 7 .

[0059] Specifically, when the automatic magnetic measuring device of the embodiment of the present invention is used to perform actual magnetic measuring operation, the computer program sends a start command to the motor controller 1 to start the motor structure, the brake is released, and the stepper motor performs the set number of rotations according to the prefabricated project to drive the Gaussian probe 9 to lift the set height. At the same time, the computer program reads the measurement data sent by the Gaussian meter 7, and also derives data with the two variables of the position of the Gaussian probe 9 and the magnetic field strength. After measurement, it is shown that the automatic magnetic measuring device of the embodiment of the present invention is used to perform actual magnetic measuring operation, and the single measurement time is less than or equal to 60 seconds, the measured points are greater than or equal to 320, and the continuous use time is greater than or equal to 6 hours.
