[0002] Plane control surveying is a basic concept in engineering surveying and geographic information systems. It refers to establishing an accurate plane coordinate system on the ground to determine the horizontal position of various land features, engineering facilities or monitoring points. This kind of measurement is crucial to map making, land management, urban planning and large-scale engineering construction.

[0003] Plane control measurement is divided into triangulation and precision traverse measurement. In triangulation, it is usually necessary to set up instruments at multiple points, and the prism position does not need to be moved. When the total station changes the setting point, the prism needs to be rotated to align with the total station. The operation is very cumbersome. At the same time, when there are many prisms, a large number of people are required to rotate the prism, and there is a deviation in the angle of the manually rotated prism to the naked eye. At present, there is no good solution to this problem. In the field of track measurement, there is an automatic rotating prism to realize CPIII measurement. When the total station moves along the line, the prism automatically rotates to reduce the workload. There is no corresponding method or device in the field of triangulation. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A prism automatic rotation device, such as Figure 1-3 As shown, it includes a connecting device 11 for connecting to a base, on which a motor device is provided, and the motor device is connected to a signal receiving device; the motor device is connected to a fixed disk claw 1 through a transition connector 2, and the fixed disk claw 1 is equipped with a prism fixing device 15.

[0024] Specifically, the connecting device 11 is used to connect the device between the base and the prism, and the installation is convenient. The motor device can rotate, thereby driving the prism connected above to rotate. The signal receiving device receives the signal sent by the total station to control the rotation angle. The signal receiving device can be arranged inside the motor device; it can also be arranged outside the motor device, and the two are connected by electrical signals. The transition connector 2 is used to connect and transition the speed output member and the fixed disk claw 1, and provide support and fixation for the fixed disk claw 1. The fixed disk claw 1 can position the fixed assembly. The fixed disk claw 1 includes three claws, and the tops of the claws are located in the same plane, which are used to assist in fixing the prism fixing device 15 to prevent tilting. The prism fixing device 15 is used to connect the prism to the prism automatic rotation device, which is convenient for disassembly and assembly. Among them, there are multiple screws 10 on the connecting device 11, which are used to fix the connecting device 11 on the prism base, and three mounting holes 17 are provided above the prism fixing device 15 for installing the prism bracket.

[0025] As another specific embodiment, it also includes an energy storage device, which includes a first box body 8, a battery 9 is provided in the first box body 8, and the energy storage device is arranged between the connecting device 11 and the signal receiving device, and the energy storage device is connected to the signal receiving device and the motor device through a line 12. In many surveying and mapping sites, there may be no reliable power grid connection. The use of an energy storage device allows the surveying and mapping equipment to operate independently without being restricted by the site. In addition, the surveying and mapping work may need to be moved quickly to different locations, and the equipment powered by the battery 9 can be quickly deployed and transferred to improve work efficiency. Furthermore, the energy storage device supplies power to the signal receiving device and the motor device, and the energy storage device is arranged between the connecting device 11 and the signal receiving device, which can simplify the arrangement of the line 12.

[0026] As another specific embodiment, a battery 9 box is provided on the first box body 8, and the battery 9 box is connected to the first box body 8 through a buckle 21 switch. A copper sheet 20 is provided inside the battery 9 box, and the copper sheet 20 is connected to the circuit 12. Since the life of the battery 9 is usually shorter than that of the device itself, the design of the replaceable battery 9 box allows the battery 9 to be replaced when the performance of the battery 9 deteriorates or the life ends, instead of replacing the entire device, thereby extending the service life of the device.

[0027] As another specific embodiment, the signal receiving device includes a second box body 19, in which a signal receiver 13 is arranged, and the signal receiving device is arranged between the connecting device 11 and the motor device. Compared with directly arranging the signal receiving device in the motor device, the independent receiver box body can directly contact the external antenna without penetrating the device housing 14, which is usually easier to tune and calibrate, and is not limited by the internal space of the signal receiving device, thereby improving the signal receiving efficiency. The signal receiving device is connected to the energy storage device and the motor device through the line 12, is directly powered by the energy storage device, and controls the switch of the line 12 of the motor device.

[0028] As another specific embodiment, the motor device includes a third box body 5, and the rotating motor 4 is connected to the third box body 5 through a plurality of metal sheets 18. The third box body 5 can protect the user from possible damage caused by direct contact with the rotating motor 4 in operation, and can prevent dust, moisture and other foreign particles from entering the rotating motor 4, thereby extending the service life of the rotating motor 4 and maintaining its performance. The metal sheet 18 can be used to fix the rotating motor 4.

[0029] As another specific embodiment, the motor device is connected to the signal receiving device via a latch structure. Once the latch structure is locked, it can provide a continuous and stable connection, ensure the reliability of the connection, and can be quickly connected and disassembled without the use of tools, greatly saving time and improving efficiency.

[0030] As another specific implementation, a first gasket 7 is provided between the energy storage device and the signal receiving device, and a second gasket 6 is provided between the motor device and the signal receiving device. The gasket can achieve shock absorption between the devices and reduce friction.

[0031] As another specific implementation, a speed change device 3 is further provided between the motor device and the transition connector 2. Since the motor device usually rotates at a high speed, the speed change device 3 can convert the high-speed rotating input shaft into a low-speed rotating output shaft, and provide more precise speed control to meet the actual fine-tuning requirements of the prism. The speed change device 3 is connected to the motor device through an assembly hole at the bottom.

[0032] As another specific embodiment, it also includes a shell 14 for accommodating all structures. The shell 14 can wrap the intermediate structure, and the shell 14 has no bottom below, and is connected to the connecting device 11 below. The connecting device 11 is connected to the shell 14 through a threaded structure.

[0033] A triangulation measuring instrument comprises a base, the upper part of which is connected to the prism automatic rotation device, the prism automatic rotation device is provided with a prism, the prism is provided with a sensor 16, and the sensor 16 is communicatively connected with a signal receiving device.

[0034] The total station signal is received by the sensor 16, and the signal direction angle information is saved and compared with the direction of the sensor 16. If they are inconsistent, information is sent to control the signal receiving device to start the rotation operation until the direction of the sensor 16 is consistent with the angle of the total station signal direction, and then information is sent to control the signal receiving device to stop the rotation operation. The signal receiving device receives different signals from the sensor 16, controls the motor through the switch, and thus controls the start and end of the rotation, so that the azimuth angle of the sensor 16 direction is consistent with the azimuth angle of the signal sent by the total station, and the alignment accuracy is high.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
