Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
In a preferred embodiment, referring to fig. 1 and 2, the method for eliminating the influence of the external magnetic field of the mower system of the present embodiment is applied to a first mower system, and the first mower system 10 includes a first base station 101, a first mower 102, and a first boundary line 103, and both ends of the first boundary line 103 are connected to the first base station 101. Specifically, the method for eliminating the influence of the external magnetic field of the mower system comprises the following steps:
s1, the first base station 101 controls the first boundary line 103 to generate a first magnetic field distribution, and sets a first magnetic field recognition rule of the first mower 102, where the first magnetic field recognition rule corresponds to the first magnetic field distribution and the mower position.
Specifically, the first magnetic field distribution includes a first inner magnetic field and a first outer magnetic field, the first inner magnetic field and the first outer magnetic field are divided by taking the first boundary line 103 as a boundary, the first inner magnetic field refers to a magnetic field inside the first boundary line 103, the first outer magnetic field refers to a magnetic field outside the first boundary line 103, the first inner magnetic field and the first outer magnetic field are different magnetic fields, and the first mower 102 determines the mower position through the different magnetic fields. The first magnetic field identification rule is a first magnetic field distribution and mower position correspondence relationship, and the first magnetic field distribution and mower position correspondence relationship includes: the first inner magnetic field corresponds to the inside of the boundary, and the first outer magnetic field corresponds to the outside of the boundary; that is, when the first mower 102 receives and recognizes the first internal magnetic field, it indicates that the first mower 102 is located within the first boundary line 103; when the first mower 102 receives and recognizes the first external magnetic field, it is indicated that the first mower 102 is located outside the first boundary line 103.
S2, the first mower 102 performs the automatic mowing operation under the action of the first magnetic field distribution and the first magnetic field recognition rule, and when the first mower 102 comes out of the first boundary line 103 under the action of the external magnetic field, the first magnetic field distribution and the first magnetic field recognition rule are adjusted.
Specifically, the first mower 102 performs the automatic mowing operation under the action of the first magnetic field distribution and the first magnetic field recognition rule, and the first mower 102 normally travels inside the first boundary line 103, and returns to the boundary when the first boundary line 103 is detected, and does not travel outside the first boundary line 103. When the first mower 102 is not driven out of the first boundary line 103 by the external magnetic field, the external magnetic field affects the position recognition of the first mower 102, and the magnetic field direction of the external magnetic field is the same as the magnetic field direction of the first inner magnetic field. This is because, when the magnetic field direction of the external magnetic field is the same as the magnetic field direction of the first internal magnetic field, the first mower 102 erroneously recognizes that the received external magnetic field is the first internal magnetic field when it is outside the first boundary line 103, and erroneously recognizes that the received external magnetic field is still outside, as indicated by a broken line box in fig. 1, which causes erroneous recognition of the first mower 102, and thus the mowing operation cannot be normally performed.
After the external magnetic field appears, in order to eliminate the influence, the first magnetic field distribution and the first magnetic field identification rule need to be adjusted, so that the magnetic fields of the first internal magnetic field and the first external magnetic field are opposite, and the corresponding relation between the first internal magnetic field and the first external magnetic field in the first magnetic field identification rule is exchanged. Further, reversing the magnetic fields of the first inner magnetic field and the first outer magnetic field means that the magnetic field direction of the first inner magnetic field is taken as the magnetic field direction of the first outer magnetic field, and the magnetic field direction of the first outer magnetic field is taken as the magnetic field direction of the first inner magnetic field. In addition, interchanging the correspondence between the first inner magnetic field and the first outer magnetic field in the first magnetic field identification rule means interchanging the correspondence between the first inner magnetic field and the first outer magnetic field, that is, before adjustment, the magnetic field direction of the first inner magnetic field is within the corresponding boundary, and the magnetic field direction of the first outer magnetic field is outside the corresponding boundary; after adjustment, the magnetic field direction of the first external magnetic field corresponds to the inside of the boundary, and the magnetic field direction of the first internal magnetic field corresponds to the outside of the boundary.
For adjusting the first magnetic field distribution, the present embodiment provides two ways to adjust the first magnetic field distribution:
the first adjustment of the first magnetic field distribution mode: the first power supply terminal and the second power supply terminal of the first base station 101 are interchanged to reverse the power supply current of the first boundary line 103, and the magnetic field reversal of the first inner magnetic field and the first outer magnetic field is realized according to the electromagnetic wave generation principle.
The second way of adjusting the first magnetic field distribution is: the first base station 101 comprises a magnetic field generation control module for controlling the generation of a magnetic field, which magnetic field generation control module is capable of controlling the direction of the magnetic field generating the magnetic field. The magnetic field generation control module receives a first magnetic field transformation instruction, and the first magnetic field transformation instruction enables the magnetic fields of the first inner magnetic field and the first outer magnetic field generated by the magnetic field generation control module to be opposite. Alternatively, the first base station 101 is provided with a mechanical key for generating the first magnetic field transformation command.
The process of adjusting the corresponding relationship of the first external magnetic field in this embodiment is as follows: the first mower 102 receives a first adjustment instruction, and the first adjustment instruction is used for interchanging the corresponding relation between the first internal magnetic field and the first external magnetic field in the first magnetic field identification rule. Alternatively, the human-machine interface of the first mower 102 receives a first adjustment instruction; or the input button of the first mower 102 generates the first adjustment command.
The embodiment solves the influence of an external magnetic field on the mower by adjusting the magnetic field distribution of the emitted magnetic field and the magnetic field identification rule of the mower, so that the mower can normally carry out mowing operation.
In a preferred embodiment, and with reference to fig. 3 and 4, the external magnetic field is generated by an external device, which is a wide variety of devices and is now described as the second mower system 20, and other external devices can be referred to for implementation. Specifically, the external magnetic field is generated by the second mower system 20, the second mower system 20 includes a second base station 201, a second mower 202, and a second boundary line 203, two ends of the second boundary line 203 are connected to the second base station 201, and a distance between the first boundary line 103 and the second boundary line 203 is smaller than a preset distance, and the second base station 201 controls the second boundary line 203 to generate a second internal magnetic field and a second external magnetic field.
When the first inner magnetic field (internal boundary magnetic field) of the first boundary line 103 is a magnetic field a and the first outer magnetic field (external magnetic field) is a magnetic field B, the first lawnmower 102 recognizes the magnetic field a as being inside the boundary and recognizes the magnetic field B as being outside the boundary. When the second inner magnetic field (the boundary inner magnetic field) of the second boundary line 203 is a magnetic field B and the second outer magnetic field (the boundary outer magnetic field) is a magnetic field a, the second lawnmower 202 recognizes the magnetic field B as being inside the boundary and recognizes the magnetic field a as being outside the boundary. However, in this case, the magnetic field outside the boundary of the first mower 102 includes not only the magnetic field B of the first boundary line 103 but also the magnetic field a of the second boundary line 203, and the magnetic field a of the second boundary line 203 has the same direction as the magnetic field a of the first boundary line 103, which makes the first mower 102 mistaken to be within the boundary but actually out of the boundary, and causes the first mower 102 to make a false judgment, which affects the mowing operation of the first mower 102.
To solve the magnetic field effect of the second mower system 20, the first magnetic field distribution and the first magnetic field identification rule are adjusted according to the technical solutions of the above embodiments. Referring to fig. 4, adjusting the first magnetic field distribution means reversing the magnetic fields of the first inner magnetic field and the first outer magnetic field, that is, taking the magnetic field direction of the first inner magnetic field as the magnetic field direction of the first outer magnetic field, and taking the magnetic field direction of the first outer magnetic field as the magnetic field direction of the first inner magnetic field. After the adjustment, the first inner magnetic field (internal magnetic field boundary) of the first boundary line 103 is a magnetic field B, and the first outer magnetic field (external magnetic field boundary) is a magnetic field a. For the first magnetic field identification rule, before adjustment, the magnetic field A is inside the corresponding boundary, and the magnetic field B is outside the corresponding boundary; the magnetic field B corresponds to the inside of the boundary after adjustment, and the magnetic field A corresponds to the outside of the boundary. After the first magnetic field distribution and the first magnetic field recognition rule are adjusted, the first mower 102 recognizes that the magnetic field B is in the boundary and recognizes that the magnetic field a is out of the boundary, and the magnetic field a generated by the second mower system 20 does not affect the recognition of the first mower 102 on the inside and outside of the boundary, so that the mowing operation can be normally performed.
The embodiment solves the influence of an external magnetic field on the mower by adjusting the magnetic field distribution of the emitted magnetic field and the magnetic field identification rule of the mower, so that the mower can normally carry out mowing operation.
