The invention discloses a detector and a detection system for object state. The detector comprises a closed box, a ball placed inside the closed box and a detection circuit arranged on the closed box,wherein the closed box is provided with a flexible inner wall, a liquid metal circuit is buried under the flexible inner wall, and a pair or a plurality of pairs of detection electrodes are led out at different positions of the liquid metal circuit; the ball is used for following the motion state of a target object, and extrusion is formed for the inner wall of the closed box, so that the actualresistance of the liquid metal circuit under the inner wall is changed; the detection circuit is connected with the pair or the pairs of detection circuits, and is used for detecting the actual resistance values at different positions of the liquid metal circuit in real time so as to reflect the actual motion state of the target object. The detection for the object state is realized by using a liquid metal as a detection resistor and the characteristic of resistance change caused by the fact that the liquid metal is shaken and extruded by the ball.
Description
technical field [0001] The invention belongs to the technical field of object motion sensing, and in particular relates to an object state detector and a detection system. Background technique [0002] At present, the motion detection of vehicles mainly uses acceleration sensors and angular velocity sensors to realize all-round monitoring of parameters such as vehicle speed and trajectory. Bumpy experience; on the other hand, the vehicle has its own shock absorption system, which can effectively reduce / eliminate the shock of a certain intensity, but when it is in an excessive shaking state, it is easy to cause loss of accessories in the shock absorption system, or even other components , at this time, the owner should slow down and pass through, thereby reducing the overall shaking of the vehicle body. However, since there is no vehicle shaking detection and corresponding safety operation prompts on the current vehicle, the owner needs to judge by himself according to his dr...
