摘要

A single-hole cantilever beam strain gauge dynamic electronic small unmanned vehicle scale, comprising a resistive strain sensor system, a voltage signal amplification circuit, an A/D data collection and conversion circuit, a controller, a resistance strain gauge measurement circuit, a display, an information input device and a scale health status monitoring system. The resistive strain sensor system uses resistance strain gauges as sensitive elements of a weighing sensor, a cantilever beam of the resistance strain gauges utilises a single elliptical hole beam structure, the plate-shaped beam is provided with one elliptical hole, a force fully acts on a centre point of an elliptical upper surface and lower surface via an object weight effect, and the resistance strain gauges are respectively adhered to an upper end and lower end of the elliptical hole, so that the four strain gauges are located in opposite stress areas in two groups, so that the force is converted onto the resistance strain gauges.
