An uninsured alarm device for climbers

摘要

The device comprises:-A shell (5) for fixing on the shoulder strap;-A pressure sensor (6) for measuring atmospheric pressure;-A sensing device (7) for connecting to the connecting rod and configured to detect the displacement of the connecting rod within the positive tilt range relative to the horizontal reference plane (pref), and the sensing device (7) configured to output a sensing signal, including:The first state indicates that the connecting rod is in the range of positive inclination,The second state indicates that the connecting rod is not in the range of positive angle;-A microprocessor (8) configured to:Calculate the atmospheric pressure change measured by the pressure sensor (6),When the atmospheric pressure changes beyond a predetermined threshold and the sensor signal is in the second state, an alarm signal is issued.chartPage 1
