[0022] Support plate 1: A storage groove 2 is provided on its upper surface to provide space for storing and protecting surveying and mapping components. A shell 3 is slidably connected inside the storage groove 2 to provide support for the setting of the surveying and mapping components. A laser rangefinder 4 is provided in the mounting hole of the outer arc surface of the shell 3. A battery 6, a single-chip microcomputer 7 and an electronic compass 8 are respectively provided inside the shell 3. The battery 6 provides power for the operation of the entire device. The terrain data is collected by the laser rangefinder 4, the azimuth of the measuring point is determined by the electronic compass 8, and the data is sorted by the single-chip microcomputer 7 to realize the mapping of the terrain. The output ends of the laser rangefinder 4 and the electronic compass 8 are electrically connected to the input end of the single-chip microcomputer 7, and the output end of the battery 6 is electrically connected to the input end of the single-chip microcomputer 7. Internal threaded rings 5 ​​are provided at both upper and lower ends of the inner arc surface of the storage groove 2. The internal threaded ring 5 is installed in cooperation with the external threaded ring at the lower end of the outer arc surface of the shell 3. When the shell 3 is threadedly connected to the internal threaded ring 5 on the upper side When the casing 3 is in the state of being connected with the internal threaded ring 5 at the lower side, the surveying and mapping component leaves the interior of the storage groove 2, and when the casing 3 is threadedly connected with the internal threaded ring 5 at the lower side, the surveying and mapping component enters the interior of the storage groove 2, reducing the probability of damage to the surveying and mapping component due to collision during transportation. A lifting handle 10 is provided on the upper surface of the casing 3, which is convenient for rotating the casing 3. The support plate surface at the lower end of the interior of the storage groove 2 is vertically slidably connected with a sliding column 11, and a top plate 12 is provided between the upper ends of the sliding columns 11. The outer arc surfaces of the sliding columns 11 are movably sleeved with springs 13, and the upper ends of the springs 13 are fixedly connected to the top plates 12, and the lower ends of the springs 13 are fixedly connected to the support plates of the storage groove 2. During the storage process, the casing 3 applies a downward thrust to the top plates 12 to overcome the elastic force of the springs 13, and the sliding columns 11 slide on the support plate surface of the storage groove 2. Under the elastic force of the springs 13, an upward force is continuously applied to the casing 3, so that the connection between the casing 3 and the internal threaded ring 5 at the lower side is more firmly established.

[0023] The support mechanism 9 is rotatably connected to the lower surface of the support plate 1. The support mechanism 9 includes a rotating leg 91, a slide groove 92 and a sliding leg 93. The rotating leg 91 is rotatably connected to the rotating frame on the lower surface of the support plate 1 through a rotating shaft. The lower surface of the annular rotating leg 91 is provided with a slide groove 92. The interior of the slide groove 92 is vertically slidably connected with the sliding leg 93.

The support mechanism 9 also includes a support plate 96. The support plate 96 is respectively arranged at the lower end of the sliding leg 93 to increase the contact area between the sliding leg 93 and the ground, so that the placement of the overall device is more stable.

[0024] The working principle of a surveying and mapping device for land reserve registration provided by the utility model is as follows: during the land reserve registration process, the surveying and mapping device is placed on the ground, and the three rotating legs 91 are relatively opened until the rotating legs 91 are in contact with the lower surface of the support plate 1. At this time, the rotating legs 91 are rotated to the maximum state, and the three legs distributed in an annular manner are used to provide support for the entire device. The terrain data is collected by the laser rangefinder 4, the azimuth of the measuring point is determined by the electronic compass 8, and the single-chip microcomputer 7 is used to organize the data to realize the mapping of the terrain. During transportation, the sliding leg 93 slides inside the slide groove 92 to make the limit bolt 95 engage with the lowermost socket 94, thereby reducing the length of the leg. At the same time, the three rotating legs 91 are closed and folded to reduce the space occupied by the entire device. At the same time, the shell 3 is rotated to disengage the threaded connection between the shell 3 and the upper internal threaded ring 5, and then the shell 3 is pushed downward and rotated again to make the shell 3 threadedly connected with the lower internal threaded ring 5, and the shell 3 is folded into the storage groove 2 to reduce the probability of damage to the surveying and mapping components due to bumps during transportation.

[0025] It is worth noting that the single-chip microcomputer 7 disclosed in the above embodiment can use a single-chip microcomputer of the PIC16F1823-I / P model, and the electronic compass 8 and the laser rangefinder 4 can be freely configured according to the actual application scenario. The electronic compass 8 can use an electronic compass of the SCM225 model, and the laser rangefinder 4 can use a reflective laser rangefinder of the T150HJG-CGQ model. The single-chip microcomputer 7 controls the operation of the electronic compass 8 and the laser rangefinder 4 using methods commonly used in the prior art.
