Abstract
The utility model discloses an outdoor actual measurement apparatus for quickly and freely switching signals with limited data acquisition systems. A wind speed sensor and a wind pressure sensor are connected with fixed double-row binding post terminal slots through data acquisition wires and then are correspondingly connected with aviation plugs on a signal switching box. According to actually-measured change in the wind direction of a wind field, measuring points required to be monitored are selected by quickly plugging the aviation plugs in order to switch signals connected with data acquisition systems in limited amount. According to actually-measured environmental wind direction, the outdoor actual measurement apparatus emphatically monitors and researches surface wind pressure of a need area as required by using limited data acquisition systems, and provides convenience for outdoor structural wind engineering actual measurement. The outdoor actual measurement apparatus is simple in structure, low in cost, easy to control, and high in precision.
