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. The total station is called as a total station because the total station can complete all measurement work on the station by arranging the instrument once, and is widely used in the field of precision engineering measurement or deformation monitoring such as ground large-scale building and underground tunnel construction.
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 grant publication No. 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 includes a total station body, a telescope, a handle, a vertical brake knob, a base, and a horizontal brake knob.
