The total station is a high-technology measuring instrument integrating light, mechanical and electrical functions, and is a surveying instrument system integrating the functions of measuring horizontal angle, vertical angle, distance (inclined distance and flat distance) and height difference.

At present, total station teaching courses are offered in many universities and universities' related professions, and there are some problems in the practice course teaching link of total station generally: (1) The measurement work needs a plurality of people to cooperatively work, is limited by cooperative conditions and safety, and is difficult to develop single person practical exercise; (2) Most practice sites for measuring courses are selected from campuses of school areas where students are located, and the students cannot go to a real site for actual measurement in practice teaching, so that the engineering forms are various and widely distributed; (3) The training is difficult to develop in real time due to the limitation of course duration and weather; (4) The total station belongs to high-precision instrument equipment, has high cost and is easy to damage, and the practical training of one hand can not be realized; (5) Traditional surveying and mapping practice teaching is generally carried out in a centralized mode, and a teacher cannot take care of training effects of each student on multiple students during practice. In general, the traditional teaching mode and teaching means of total stations are presented as a single and a lag, derailment with the digital age of high-speed development.

In this regard, the chinese patent of the utility model with the grant bulletin number CN206339231U discloses a mapping instrument simulation model device, which includes a total station simulation model device, a mobile phone installation device, an operation panel simulation device, a sensor signal acquisition device and a server (i.e., a PC training terminal), wherein the total station simulation model device includes a total station simulation model and an angle sensor, and the total station simulation model is a simulation structure of appearance and mechanical functions of the total station, and can realize rotation and pressing functions; the angle sensor is arranged inside each rotation adjusting component in the total station simulation model and is used for collecting angle change signals of each rotation adjusting component; the sensor signal acquisition device is connected with a data interface of the total station model device, the angle variation acquired by the angle sensor and the variation of the keyboard Hall keys in the operation panel simulation device are collected, the variation is transmitted to the PC training terminal, the action response of each simulation part of the virtual instrument in the virtual simulation training operation software of the measuring instrument is realized, meanwhile, the program background performs visual angle conversion and measurement data processing on the operation signal, and visual angle scene data of an eyepiece of the virtual total station is transmitted to a mobile phone screen in the total station simulation model.

The working principle of the total station for simulation teaching in the invention is as follows:

when the fine focusing training is performed, the objective focusing knob 15 is rotated, the second angle sensor 121 detects an angle change signal, the angle change signal is finally transmitted to the PC training terminal by the second Bluetooth module 123, the PC training terminal sends an instruction to the fine focusing view screen 16 through a wifi signal according to the setting of the software system, the definition of the whole picture displayed on the fine focusing view screen 16 is changed, and the simulation operation of one-time objective focusing is completed. By rotating the eyepiece focusing knob 14, the first angle sensor 111 detects an angle change signal, and finally the angle change signal is transmitted to the PC training terminal by the first Bluetooth module 114, and the PC training terminal sends an instruction to the fine sight screen 16 through a wifi signal according to the setting of a software system, so that the definition of a cross wire displayed on the fine sight screen 16 is changed, and the simulation operation of one-time eyepiece focusing is completed. Therefore, the total station for simulation teaching can train students to grasp the operation of the two focusing knobs, is closer to actual teaching, and can achieve better teaching effect.

In the training process, the images displayed on the fine view screen 16 are directly observed through the eyepiece focusing knob 14, the eyepiece barrel and the lens 133, so that a telescope is omitted, the display images of the fine view screen 16 are prevented from being excessively amplified, the PC training terminal can be used for directly controlling the amplification of the display images of the fine view screen 16 by a reasonable multiple, and the better observation effect is achieved by matching with the effect of the lens 133, so that the feasibility is stronger compared with the prior art.

When the coarse sight training is carried out, the total station for simulation teaching is located indoors and is not carried to the site at all, so that in order to simulate the picture seen by students using the coarse sight device on the physical total station outdoors, the coarse sight screen 3 is additionally arranged, and the picture displayed by the coarse sight screen 3 replaces the actual coarse sight observation picture of the students. Because the main body structure of the total station is basically unchanged, the relation of each shafting is kept correct, the shafting relation is transmitted to the PC training terminal through the 232 interface of the original machine, and the PC training terminal correspondingly sends instructions to the coarse-aiming view screen 3 according to the information. The rough sight screen 3 can rotate 180 degrees back and forth, and when the rough sight screen 3 is used for selecting a mobile phone, the mobile phone is provided with a gyroscope, and the system can operate for signal identification of the left and right of the disc, so that the sight is switched, namely, after the mobile phone is turned 180 degrees, the picture can be automatically inverted, and the observation is convenient. Meanwhile, when the user operates the mobile phone in the left or right direction, the mobile phone is still at one side, the student rotates the fine view module 1 by operating the knob of the original machine, the horizontal angle or the vertical angle is changed, the 232 interface of the original machine transmits angle information to the PC training terminal, and the PC training terminal returns to the coarse view screen 3, so that the coarse view is controlled to change in the corresponding horizontal angle or vertical angle direction, and synchronization is realized.

In the actual measuring process of the horizontal angle, the vertical angle and the distance, the calibration simulation screen 5 replaces the original total station operation panel, the relevant information input under the virtual scene and the control of the virtual instrument are realized, the real total station needs to operate on the operation panel, the real total station operates on the calibration simulation screen 5, the calibration simulation screen 5 is in control connection with the PC training terminal, and the functions of the original machine operation panel are simulated.
