Through real-time positioning, abnormal conditions of personnel can be discovered in time, and the activity trajectory of personnel can be recorded and analyzed to optimize the operation process and safety management.

[0003] Most of the existing personnel positioning is carried out through GPS and other devices, but the positioning equipment is often only tested based on the positioning parameters before being put into use. The test results cannot cope with the actual movement state of the personnel and cannot provide accurate information when the personnel are moving, which is extremely inconvenient. Therefore, a 3D test device for personnel positioning simulation is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] 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.

[0035] Embodiment 1, by Figure 1-4A 3D testing device for personnel positioning simulation is provided. The present invention comprises a base 1, a three-axis slide 2 is fixedly installed on the top of the base 1, a signal transceiver module 3 is fixedly installed on the mobile end of the three-axis slide 2, a trajectory capture sensor plate 4 is fixedly installed on the top of the base 1, a laser ranging module 5 corresponding to the trajectory capture sensor plate 4 is fixedly installed on the outside of the signal transceiver module 3, a test frame 6 with adjustable height is fixedly installed on the top of the base 1, a linear slide 7 is fixedly installed on the inner side of the test frame 6, and a positioning module 8 wirelessly connected to the signal transceiver module 3 is connected to the outer side of the test frame 6 and the outer side of the mobile end of the linear slide 7.

[0036] Furthermore, the track capture sensing plate 4 is a whole photosensitive plate, and the laser ranging module 5 is an infrared rangefinder.

[0037] Furthermore, an interruption test device 9 is fixedly installed on the top of the base 1 , and a height adjustment component 10 is provided at the connection between the test frame 6 and the base 1 .

[0038] Furthermore, the height adjustment assembly 10 includes a hydraulic push rod 101 that supports and connects the test frame 6, a marking ruler 102 is fixedly installed on the top of the base 1, and a marking sleeve 103 that is sleeved on the outside of the marking ruler 102 is connected to the connection between the hydraulic push rod 101 and the test frame 6.

[0039] In particular, the marking ruler 102 can be a grating ruler, which can realize intelligent height recognition and feedback data in conjunction with the marking sleeve 103. When the height needs to be fine-tuned, it is only necessary to move the hydraulic push rod 101 to drive the test frame 6 to move up and down, thereby adjusting the height through the marking ruler 102.

[0040] Furthermore, the blocking test device 9 includes a transport slide 91 fixed on the top of the base 1, and a blocking cover 92 is fixedly connected to the top of the moving end of the transport slide 91. A receiving photoelectric switch 93 corresponding to the laser ranging module 5 is fixedly installed on the inner side of the blocking cover 92, and the receiving photoelectric switch 93 is connected to the transport slide 91.

[0041] Furthermore, the inner side of the cross section of the shielding cover 92 includes the entire cross section of the three-axis slide 2 , and pneumatic shielding plates are provided on the left and right sides of the shielding cover 92 .

[0042] Furthermore, both the shielding cover 92 and the pneumatic shielding plate are composite plates, and the composite plates are formed by concrete plates wrapped with steel bars.

[0043] When the blocking test device 9 is working, the transport slide 91 first moves the blocking cover 92 to start moving until the receiving photoelectric switch 93 and the laser ranging module 5 trigger a stop command, so that the transport slide 91 stops moving and the blocking cover 92 stops. Then the pneumatic blocking plate moves and increases the blocking angle to complete the ready operation.

[0044] Further, it also includes a signal processing module, a debugging module and a signal simulation unit;

[0045] The signal processing module processes the signal data uniformly;

[0046] The debugging module controls the three-axis slide 2, the linear slide 7 and the positioning module 8;

[0047] The signal simulation unit is connected to the signal processing module and performs three-dimensional modeling simulation on the transmitted signal.

[0048] Furthermore, it also includes a signal visualization device, which is connected to the signal simulation unit and outputs three-dimensional modeling simulation data.

[0049] Working principle:

[0050] When debugging begins, the motion data is input through the debugging module, so that the three-axis slide 2 starts to simulate the human motion trajectory, thereby driving the signal transceiver module 3 to move. At this time, the trajectory capture sensor board 4 can record the up, down, left, and right azimuth displacements of the signal transceiver module 3, and the laser ranging module 5 can record the front and back azimuth displacements of the signal transceiver module 3, so that the motion trajectory 3D model can be established through the signal processing module;

[0051] At the same time, when the signal transceiver module 3 moves, it always exchanges signals with the positioning module 8, and the signal transceiver module 3 is positioned by the positioning module 8. The positioning data is processed by the signal simulation unit to establish a simulated 3D model. At this time, the motion trajectory 3D model and the simulated 3D model are compared to know the accuracy of positioning in the current state;

[0052] When adjustment is needed, the three-axis slide 2, the linear slide 7, the positioning module 8 and the height adjustment component 10 can be controlled through the debugging module. The four components correspond to the walking attributes of the personnel in the simulation process, the spacing of the positioning module 8, the power of the positioning module 8 and the height of the positioning module 8 from the ground. Through the adjustment of the four attributes, the unobstructed positioning performance between the positioning module 8 and the signal transceiver module 3 can be tested in detail;

[0053] After the unobstructed positioning performance test is completed, the blocking test device 9 can be debugged to start testing the positioning performance between the positioning module 8 and the signal transceiver module 3 in the blocked state. At the same time, during the test, the power of the positioning module 8 should be adjusted to the maximum to facilitate emergency positioning in emergency situations. At the same time, the position of the signal transceiver module 3 should be adjusted during the test to test whether the position change can be detected when blocking occurs.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
