Abstract:

A ranging system and ranging method, the ranging system comprising: a ranging apparatus and a terminal device (3). The ranging apparatus comprises a measuring wheel (1), a rotating shaft provided on the measuring wheel (1), and an electronic counter (2) connected to the rotating shaft and used to obtain distance information from the measuring wheel. The ranging apparatus or the terminal device (3) also comprises an angle sensor. The terminal device (3) and the ranging apparatus are respectively provided with a communication module. The terminal device (3) comprises a data processing module configured to generate, according to ranging information from the electronic counter (2) and angle information from the angle sensor, a traveling trajectory plot of the measuring wheel in real time. Thereby, a drawing of the traveling trajectory can also be generated in real time on the basis of a ranging function, such that working efficiency is effectively increased. A function of marking lines according to a pre-designed drawing in a construction site can also be achieved by cooperating with a marking equipment (4). The present invention has a simple structure, and is lightweight and flexible.
