Title:
MEASUREMENT INFORMATION ACQUISITION METHOD AND WORK VEHICLE FOR FIELD STRENGTH MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2018/123669
Kind Code:
A1
Abstract:
Provided is a work vehicle for field strength measurement that is capable of associating causes of radio wave reflection and leakage with surrounding objects and acquiring easy-to-understand measurement information. In the present invention, while a radio-wave-measurement vehicle 1 travels through an information acquisition area, a field strength measurement device 3, which receives field strength detection information at a prescribed timing from lower, middle, and upper field strength distribution detection modules 21, 22, 23 that are provided at different installation heights for the purpose of measuring the field strengths of received radio waves, generates two-dimensional lower, middle, and upper field strength distribution maps EFD-L, EFD-M, EFD-H and supplies the same to a laptop computer 5. The laptop computer 5, which receives two-dimensional scanning data from first and second laser scanners 41, 42 at a prescribed timing and generates three-dimensional surrounding object data, overlays the three-dimensional surrounding object data and two-dimensional field strength distribution maps and displays the same three-dimensionally on a display screen 5d.
