Alternatively, on the basis of the horizontal rotation mechanism shown in fig. 2, as shown in fig. 3, the truss mechanism 20 includes: a truss car box body 201, a first wheel shaft 202, a second wheel shaft 203, four track wheels 204, two tracks 205, a second stepping motor 206, a first chain wheel 207, a second chain wheel 208 and a transmission chain 209;

In the embodiment of the present invention, the third stepping motor 301 drives the wire spool 302 to rotate in the forward direction or in the reverse direction under the control of the controller 50. When the wire spool 302 is rotated in the forward direction, more wires 303 are wound on the wire spool 302, thereby moving the induction source 40 vertically upward to increase the relative height between the test object 60 and the induction source 40; when the wire spool 302 is reversely rotated, a portion of the wire 303 wound on the wire spool 302 is released, thereby vertically moving the induction source 40 downward to reduce the relative height between the test object 60 and the induction source 40.
Optionally, on the basis of the horizontal rotation mechanism shown in fig. 2 and the truss vehicle mechanism shown in fig. 3, a plurality of test parameters may be preset, each test parameter includes an angle parameter, a distance parameter, and a height parameter, and then the controller 50 may control the horizontal rotation mechanism 10, the truss vehicle mechanism 20, and the telescoping mechanism 30 to operate according to the angle parameter, the distance parameter, and the height parameter in each test parameter, so as to change the relative angle, the relative distance, and the relative height between the test object 60 and the induction source 40.
Specifically, the controller 50 is configured to, for each of at least one preset test parameter, control the first stepper motor 102 to rotate according to an angle parameter included in the test parameter, control the second stepper motor 206 to rotate according to a distance parameter included in the test parameter, and control the third stepper motor 301 to rotate according to a height parameter included in the test parameter.

the controller 50 converts the direction angle α into the pulse number required to rotate, and transmits the converted pulse number to the first stepping motor 102 through the data line, and the first stepping motor 102 drives the vertical rotating shaft 103 to rotate, so that the direction of the test object 60 generates a steering direction of α degrees;

the controller 50 converts the vertical distance z into the number of pulses to be rotated, and transmits the converted number of pulses to the third stepping motor 301 through the data line, and the third stepping motor 301 drives the wire spool 302 to rotate, so that the induction source 40 generates vertical displacement of z;
after the controller 50 adjusts the relative position between the test object 60 and the induction source 40 according to the test parameters, the controller 50 excites the induction source 40 to emit induction signals through the data lines, the test object 60 measures the relative spatial position of the induction source 40 according to the induction signals emitted by the induction source 40, the test object 60 sends induction results to the controller 50 through the data lines, and the controller 50 records the test parameters and the induction results used at this time.
After recording of the test parameters and the sensing results is completed for one test parameter, the controller 50 initializes the entire apparatus, so that the horizontal rotation mechanism 10, the truss vehicle mechanism 20, and the telescoping mechanism 30 are reset, and then the controller 50 executes the above processing procedure for the next test parameter until all the test parameters are executed, and obtains the test parameters and the sensing results recorded for each test parameter.
In the embodiment of the present invention, each test parameter may be stored in an excel table to form an excel configuration file, and the controller 50 may sequentially read each test parameter from the excel configuration file. After the relative position adjustment is completed for one test parameter and the sensing result of the test object is obtained, the test parameter and the corresponding sensing result may be stored in a table, which may be specifically shown in table 1 below.
