Description

technical field [0001] The invention relates to the field of surveying and mapping acquisition, in particular to a surveying and mapping acquisition system. Background technique [0002] The current surveying and mapping methods are divided into two parts: internal and external. The necessary point coordinates are measured by the field, and the ground features represented by the relevant point coordinates are drawn by the internal industry in combination with the surveying and mapping sketches using drawing software. Some existing surveying and mapping acquisition systems use an external instrument for the surveying and mapping instrument. This external instrument can obtain the data collected by the field surveying and mapping instrument (take the total station as an example) in real time, and display these data in a reasonable way. On the external device, at the same time, according to the interaction between the user and the operation site of the external device, the seco...

Problems solved by technology

figure 1 It is the circuit schematic diagram of the power supply part of the traditional surveying and mapping acquisition system, from figure 1 It can be seen from the figure that the power supply part of the traditional surveying and mapping acquisition system uses many components, the circuit structure is complex, the hardware cost is high, and it is inconvenient to maintain

In addition, because the power supply part of the traditional surveying and mapping acquisition system lacks corresponding circuit protection functions, such as: lack of current limiting protection functions, resulting in poor circuit safety and reliability
