At present, the total station teaching course has been seted up to the relevant specialty of a lot of colleges and universities, and the practice course teaching link of total station ubiquitous has some problems: (1) the measurement work needs multi-person cooperative operation and is limited by cooperative conditions and safety, so that single person practice training is difficult to carry out; (2) most of the practice sites of the measurement courses are selected from the campus of the school district where the students are located, the engineering forms are various, the distribution is wide, and the students cannot go to a real construction site to carry out actual measurement during practice and teaching; (3) due to the limitation of the course time and weather, real-time training is difficult to carry out; (4) the total station belongs to high-precision instrument equipment, is high in cost and easy to damage, and cannot be used for training by one hand; (5) traditional survey and drawing practice teaching generally develops in a centralized way, and one teacher can not take care of the training effect of each student to a plurality of students during practice. In general, the traditional teaching mode and teaching means of the total station are simplified and lagged behind, and are derailed from the digital era of high-speed development.

To this end, chinese utility model patent with the publication number CN206339231U discloses a surveying 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, the total station simulation model is a simulation structure of the appearance and mechanical functions of the total station, and can realize the rotating and pressing functions; the angle sensor is arranged in each rotary adjusting part in the total station simulation model and used for acquiring angle change signals of each rotary adjusting part; the sensor signal acquisition device is connected with a data interface of the total station model device, collects angle variation acquired by the angle sensor and variation of a keyboard Hall key in the operation panel simulation device, transmits the variation to the PC training terminal, realizes action response of each simulation part of a virtual instrument in the virtual simulation practical training operation software of the measuring instrument, simultaneously carries out visual angle conversion and measurement data processing on an operation signal by the program background, and transmits visual angle scene data of an eyepiece of the virtual total station to a mobile phone screen in the total station simulation model.
