The invention provides a fuse indicating device and a fuse, and the indicating device comprises a magnetic drive switch which is suitable for being arranged close to the fuse and has at least a first switch state and a second switch state; the magnetic drive switch is suitable for being switched from a first switch state to a second switch state under the influence of an induced magnetic field generated when the fuse is powered on, and is switched from the second switch state to the first switch state when being not influenced by the induced magnetic field; the alarm device is connected with the magnetic drive switch and is matched with the magnetic drive switch to form a current loop at least when the magnetic drive switch is in the first switch state; and the power supply is connected in series with the magnetic drive switch and the alarm and is suitable for forming an indication loop to supply power to the alarm. The indicating device has better reliability.

The invention relates to the technical field of body armor testing, in particular to a body armor damage positioning method and system based on a flexible sensor network, and the method comprises the steps: collecting a multi-mode impact signal generated by an impact event through a partition heterogeneous flexible sensor network, and synchronously collecting the posture data of a wearer; carrying out adaptive anti-interference preprocessing on the multi-mode impact signal, and dynamically adjusting a filtering parameter according to the attitude data to obtain a pure impact signal; the signal receiving time difference of the sensing nodes is extracted, dynamic medium coefficient calibration is carried out in combination with sensing network deformation characteristics, and impact point plane coordinates are solved through an optimization algorithm; extracting impact energy related parameters to divide energy levels, inverting the penetration depth of an impact object through an energy attenuation model, and forming damage three-dimensional coordinates with impact point plane coordinates; and dynamically matching the damage grading threshold values to obtain a quantitative damage result. According to the scheme, the damage positioning and evaluation precision is greatly improved through an accurate adaptation mechanism of the special medium characteristics of the body armor and the dynamic deformation.

The utility model discloses an automobile anti-collision beam with a traction function, which comprises an anti-collision beam and a base arranged on the anti-collision beam, the base is provided with a traction hole, the traction hole is positioned below the anti-collision beam and is parallel to a longitudinal beam of an automobile chassis, and a traction hook is movably mounted in the traction hole; the two ends of the anti-collision beam are connected with the energy absorption boxes through connecting pieces.
