Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of channel control, and more particularly to a magnetic navigation sensor with angle detection. Background Art
[0002] The main principle of the magnetic navigation sensor with angle detection for intelligent sensing is that the sensor uses the internal magnetoresistive sensor element to sense changes in the surrounding magnetic field. When the sensor moves, the magnetic field sensing element inside it will detect changes in the direction and intensity of the magnetic field. By processing and analyzing the magnetic field measurement data, the sensor can calculate the angle information related to the magnetic field change. This usually involves converting the analog signal output by the magnetic field sensing element into a digital signal, and further filtering, amplifying and calibrating it, so as to know the angular position of the magnetic stripe, realize channel control, and move according to the specified channel.
[0003] After searching, in the existing public documents, the Chinese patent announcement number CN205300596U discloses an AGV magnetic stripe navigation sensor, the main chip of which is a second-axis magnetometer through the second signal acquisition circuit; an AGV magnetic stripe is arranged between the first-axis magnetometer and the second-axis magnetometer. This utility model improves the problems of low detection accuracy and poor real-time performance of traditional detection point-type magnetic stripe sensors. At the same time, the relative position of the magnetic stripe sensor and the magnetic stripe is expressed in the form of a continuous digital quantity. However, this technology has the following problems.
[0004] When the magnetic navigation sensor is used for channel control, although it can sense the changes in the magnetic field of the surrounding magnetic stripes and calculate the angle information related to the magnetic field changes, in actual use, it is still necessary to sense the changes in the magnetic field of the surrounding magnetic stripes to ensure that the intelligent sensing device controls the driving along the specified channel. Once there are a lot of debris or foreign matter on the magnetic stripe and it is not removed in time, this will lead to foreign matter sensing between the magnetic stripe and the magnetic navigation sensor, making the channel control of the magnetic navigation sensor extremely prone to misjudgment, thereby greatly reducing the channel control accuracy of the magnetic navigation sensor. For this reason, a magnetic navigation sensor with angle detection is needed. Summary of the invention

[0037] The use principle of the magnetic navigation sensor with angle detection of the present invention is as follows: Step 1: When locating the gap, first connect the shell 1 to the intelligent sensing device of the AGV mobile machine, and place the shell 1 above the magnetic strip. Insert two bolts into the holes of the shell 1 to install the shell 1 on the intelligent sensing device of the AGV mobile machine. Use the wiring harness to connect to the wiring port 17, and fix the shell 1. When the indicator light 18 is green, it means that the magnetic resistance sensor 2 is in normal use.
[0038] Then, the first micro motor 5 is started through the controller 16, and the first micro motor 5 drives the linkage screw 4 to rotate. The linkage screw 4 carries the concave sleeve block 6 to move right under the action of the thread transmission force, and the concave sleeve block 6 can slide right along the inner wall of the support frame 3, and the concave sleeve block 6 drives the connecting shaft 7 to move right.

[0039] At the same time, the sleeve push plate 11 drives the distance sensor 12 to move downward, and the sleeve push plate 11 will simultaneously drive the two shafts 20 to move downward, and the shafts 20 drive the processing sleeve 21 to move downward, the bottom ends of the two processing sleeves 21 are located on the upper surface of the magnetic strip, and there is a gap between the processing sleeve 21 and the magnetic strip, and at the same time, the distance between the distance sensor 12 and the ground is sensed by the distance sensor 12. When the distance value sensed by the distance sensor 12 is the same as the distance value set by the controller 16, the first micro motor 5 is turned off by the controller 16.
[0040] Step 2. When the magnetic navigation sensor is used, when the shell 1 is moving, the changes in the direction and intensity of the magnetic field are detected by the magnetoresistive sensor 2 inside the shell 1, and the angle information related to the magnetic field change can be calculated by the angle calculator 19, thereby realizing the angle detection operation.

[0043] Step 4: During linkage processing, the micro reduction motor 24 drives the bidirectional screw 23 to rotate. The bidirectional screw 23 makes the two articulated sleeve blocks 25 move to the left and the other articulated sleeve block 25 moves to the right. The articulated sleeve block 25 drives the articulated shaft 26 to move to the left. The articulated shaft 26 makes one end of the push sleeve rod 27 move to the left, and the other end of the push sleeve rod 27 drives the articulated push shaft 28 to rotate counterclockwise. The articulated push shaft 28 drives the processing sleeve The plate 21 rotates counterclockwise, the processing sleeve 21 drives the rotating shaft 20 to rotate counterclockwise, the rotating shaft 20 rotates counterclockwise on the sleeve push plate 11, and the other processing sleeve 21 rotates clockwise, so that the two processing sleeves 21 can expand the debris sensed by the visual sensor 33, so that the debris is processed to the positions on both sides, thus avoiding the presence of debris on the magnetic strip to cause recognition obstruction, ensuring that the magnetoresistive sensor 2 can perform precise channel control sensing according to the magnetic strip, and accurately control movement along the channel.
