[0039] The terrain adapting member comprises an electric telescopic rod 3, a servo motor, a pneumatic rod 5, a pneumatic regulator 4, and an inertial sensor (not shown in the figure) arranged on the upper end surface of the placing seat 2 and collecting the inclination angle data of the surveying instrument body 1, one end of the electric telescopic rod 3 is drivingly connected with the servo motor to form a coarse adjustment part, the coarse adjustment part is arranged on the lower end surface of the placing seat 2, the other end of the electric telescopic rod 3 extends away from the lower end surface of the placing seat 2 and is connected with one end of the pneumatic rod 5, the pneumatic regulator 4 is arranged on the outer wall of the pneumatic rod 5 and is drivingly connected with the pneumatic rod 5, the other end of the pneumatic rod 5 is connected with the flexible contact member;

[0040] Optionally, the surveying instrument body 1 and the placing seat 2 are detachably connected.

[0041] Optionally, the transfer member 9 further comprises a control panel (not shown in the figure), the control panel is arranged on the upper end surface of the placing seat 2, and at least two control buttons (not shown in the figure) are arranged on the control panel.

[0042] Meanwhile, when the surveying instrument body 1 needs to be used for measurement, the servo motor and the pneumatic regulator 4 are controlled through the control buttons on the control panel, so that the extension length of the electric telescopic rod 3 is controlled, and the posture of the surveying instrument body 1 is stabilized, so as to improve the accuracy and reliability of the whole surveying process.

[0043] Similarly, the pneumatic rod 5 is adjusted by controlling the control buttons to control the pneumatic regulator 4, so as to control the pneumatic rod 5. The pneumatic rod 5 is arranged in a pneumatic telescopic structure.

[0044] In the embodiment, the control of the pneumatic rod 5 and the electric telescopic rod 3 is realized through the control buttons, so as to control the electric telescopic rod 3 and the pneumatic rod 5.

[0045] The control of the control buttons on the electric telescopic rod 3 and the pneumatic rod 5 is a technology known to those skilled in the art, and thus will not be described here.

[0046] The servo motor and the pneumatic regulator 4 linearly adjust the extension amount of the electric telescopic rod 3 and the pneumatic rod 5 according to the inclination angle data.

[0047] In the embodiment, the mapping device further comprises a central processor (not shown in the figure) which is in control connection with the terrain-adaptive member, the flexible contact member and the transfer member 9 respectively, and the central processor controls the terrain-adaptive member, the flexible contact member and the transfer member 9 to improve the reliability and stability of the whole device.

[0048] The control of the central processor on the terrain-adaptive member, the flexible contact member and the transfer member 9 is a technical means familiar to those skilled in the art, and thus will not be described in detail in this embodiment.

[0049] In the mapping process, the mapping instrument body 1 needs to be kept horizontal to ensure the accuracy of the measurement data. First, the inertial sensor (IMU) collects the X-axis and Y-axis tilt angle data (Pitch, Roll) of the current mapping instrument body 1 and transmits the data to the central processor. After the central processor analyzes the tilt angle data, it calculates the current tilt error and calculates the adjustment amount ΔL required for each support point based on the trigonometric function. First, the servo motor drives the electric telescopic rod 3 for coarse adjustment, i.e. adjusting the height of each support leg to approach the target horizontal state. In this process, the optical encoder (set inside the rod body of the action telescopic rod) monitors the adjustment amount of the action telescopic rod in real time and feeds back the data to the central processor to ensure the adjustment accuracy. If the mapping instrument body 1 still has slight tilt (error > ±0.1°) after coarse adjustment, the air pressure regulator 4 is started to control the air pressure rod 5 for fine adjustment. The central processor calculates the required air pressure change amount according to the current tilt state and changes the internal pressure of the air pressure rod 5 by controlling the air pressure regulating valve, thereby realizing more precise height adjustment. The adjustment accuracy of the air pressure rod 5 can reach ±0.1mm, which can further optimize the horizontal state of the mapping instrument and reduce errors. After adjustment, the inertial sensor continuously monitors the attitude of the mapping instrument and automatically triggers fine adjustment when detecting external vibration or slight changes in the ground to maintain the stability of the equipment. The whole process does not require manual intervention and can realize fully automatic adjustment, dynamic adaptation to different terrains, ensure that the mapping instrument always maintains precise level in complex environments such as lawns, slopes and sandy ground, and improve the mapping accuracy and reliability.

[0050] The electric telescopic rod 3 in the terrain-adaptive member cooperates with the air pressure rod 5 to enable the mapping instrument to adapt to the height changes of different terrains, ensure that the whole system has automatic leveling capability, be suitable for slopes, rugged terrain and irregular ground, and improve the mapping accuracy.

[0051] Optionally, the flexible contact member comprises a fixing base 7, a memory alloy 19, a heating base 10, a heater 14, a current controller, a support rod 12, and at least one pressure sensor, the fixing base 7 supports the heating base 10, the heating base 10 is provided with a heating cavity 13, one end of the support rod 12 is arranged on one side of the heating base 10 and connected with one end of the memory alloy 19, the other end of the memory alloy 19 is provided with a clamping table 20 and wedged into the heating cavity 13, the middle part of the memory alloy 19 close to one end of the clamping table 20 is provided with a heating part 21, the heater 14 is arranged in the heating cavity 13 and arranged opposite to the heating part 21, and at least one pressure sensor is arranged on the lower end face of the other end of the support rod 12 (i.e. on the end face in contact with the ground).

[0052] The current controller is electrically connected with the heater 14.

[0053] In the embodiment, the memory alloy 19 is SMA shape memory alloy 19.

[0054] Optionally, the flexible contact member further comprises a contact pad 8, the contact pad 8 is arranged on the contact end face of the support rod 12 and the surveyed ground.

[0055] The contact pad 8 is provided with a placing cavity, and the placing cavity is filled with non-Newtonian fluid.

[0056] Optionally, the contact pad 8 is made of silicone rubber material.

[0057] When the surveying instrument needs to be adjusted stably, the whole device first detects the stress state of the ground support point through the pressure sensor and transmits the data to the central processor. If the pressure of a certain support point is too large or too small, the central processor will analyze the deviation from the target stable state and decide whether to adjust the shape. If adjustment is needed, the central processor sends a PWM signal to the current controller to control the heater 14 to start or stop, thereby heating or cooling the memory alloy 19 (SMA).

[0058] When the heater 14 is powered on, the temperature in the heating cavity 13 rises, and the memory alloy 19 changes shape after being heated, causing the support rod 12 to slightly elongate or shorten to adapt to the height difference of different ground, and the adjustment range can be controlled within ±0.1mm, ensuring that the surveying instrument body 1 remains horizontal. The heating process is controlled by the feedback of the temperature sensor to prevent overheating or excessive adjustment. When the central processor detects that the support point pressure returns to the target range, or the inclination angle of the inertial sensor reaches ≤±0.1°, the central processor will stop heating, and the memory alloy 19 will return to a new stable state.

[0059] Optionally, the outer wall of the heating seat 10 is provided with a heat dissipation window, and the outer wall of the heat dissipation window is provided with a heat dissipation fin 11.

[0060] If the surveying instrument works in a high-temperature environment or a low-temperature environment, the entire device can also be temperature-adjusted through the heat dissipation window and the heat dissipation fin 11 to prevent temperature fluctuations from causing adjustment errors. In addition, if the external environment or equipment vibration causes slight changes in the support point pressure, the entire device can quickly fine-tune the memory alloy 19 through rapid pulse heating to ensure long-term stability. The entire process is automated and dynamically adjusted in real time, without the need for manual intervention, ensuring that the surveying instrument can maintain accurate measurement in various complex terrains.

[0062] Among them, by nesting at least three limiting seats 22 on the outer wall of the heating seat 10, and by hinging the limiting rod 6 to the fixing seat 7, an additional lateral support structure is formed, effectively improving the stability and lateral force resistance of the surveying device. When the surveying device is used on complex terrains such as slopes, courts, and rugged ground, the limiting rod 6 can be fine-tuned according to the terrain changes to ensure that the equipment remains stable and to avoid tilting or deviation of the surveying instrument due to excessive unilateral stress. In addition, this structure can reduce the lateral deformation of the air pressure rod 5 during long-term use, improve durability, and has shock resistance, which can effectively absorb environmental vibrations and wind effects, reduce measurement errors, and thus improve the accuracy and reliability of the surveying data.

[0063] Through the cooperation of the memory alloy 19 in the flexible contact component, the support rod 12, and the non-Newtonian fluid buffer layer, the surveying instrument can uniformly distribute the stress on soft ground (such as grass, sand, and rubber tracks), reduce local subsidence, improve support stability, ensure that the entire system has shock resistance and long-term measurement stability, and avoid the influence of ground vibration or inclination on the surveying data.

[0065] In the process of transferring, the expansion driving mechanism drives at least three expansion rods 15 to perform telescopic action, the position of the support base 17 can be adjusted, so as to change the horizontal plane where the sliding wheels are located is lower than the current horizontal plane where the support rods 12 are located, so that the whole device can be easily pushed and moved, thereby improving the convenience of moving the whole device.

[0066] Through the cooperation of the expansion driving mechanism in the transfer member 9 and the sliding wheels, the equipment can be freely switched between the static mapping mode and the dynamic moving mode, ensuring that the whole system has high efficient moving convenience, can quickly transfer the mapping position, improves the work efficiency, and at the same time ensures the stability of the equipment when mapping.
