The utility model discloses a non-visual automatic protection frame device, and belongs to the technical field of protection technologies in the debugging and running process of a robot. The robot comprises a frame, the frame comprises an upper layer and a lower layer, the upper layer is provided with a driver, a controller and a power source, the lower layer is used as a robot activity space, and a movement mechanism is arranged at the bottom of the frame; the top of the protection mechanism is connected with the top of the frame, and the bottom of the protection mechanism penetrates through the upper layer of the frame to be connected with a robot; the controller, the driver, the protection mechanism and the movement mechanism are in communication connection; according to the utility model, the tension sensor and the horizontal sensor are ingeniously combined, so that the spatial position of the robot relative to the protective frame can be accurately sensed. By means of the innovative design, the position of the protection frame can be automatically adjusted, it is guaranteed that the robot is located in a safety protection center area all the time, and the protection effect is greatly improved.

The application discloses a lane line optimization target screening method with state hysteresis, and belongs to the technical field of intelligent driving and vehicle longitudinal control. The method first acquires lane line parameters and vehicle motion parameters through a camera and a vehicle body sensor, calculates a lane center line, a short-time trajectory of the vehicle and a lateral error, and extracts a first derivative of the lane center line; then, a state machine containing six behavior states is used to realize accurate behavior recognition in combination with a lateral error and a first derivative threshold constraint, so that road bending and real lane changing misjudgment are avoided; when the behavior state is switched from lane changing having crossed a line to centering / offset keeping, a preview deviation limiter timer is started, and the sudden change of the preview lateral error is suppressed within a timing window; and finally, a path is screened based on an optimized lane center line fitting, and target screening is completed by adaptively scaling a channel width. The application improves the stability and accuracy of target screening under complex working conditions, reduces unnecessary acceleration and deceleration, and enhances driving comfort and system robustness.

The application discloses a kind of anti-falling device, including body and briquetting assembly;Body is equipped with installation cavity and guide rail passage, guide rail passage is located installation cavity side and both are communicated;Briquetting assembly includes first briquetting, second briquetting, briquetting axle, big pin shaft and small pin shaft, briquetting axle is located in installation cavity and both ends are fixed on the opposite inner side wall of body, first briquetting is rotatably connected with briquetting axle, big pin shaft is rotatably connected at least one of first briquetting and second briquetting and rotatably or fixedly connected with the other, small pin shaft is fixedly connected with first briquetting and second briquetting, and one end of second briquetting is exposed outside installation cavity;When force is applied to the exposed end of second briquetting, it rotates around briquetting axle together, so that the end of first briquetting towards guide rail passage is close to or away from, and small pin shaft is broken, and first briquetting and second briquetting are relatively rotated until abutting after small pin shaft is broken.The application can effectively solve the problem of instantaneous impact force generated during traditional braking and the problem of easy injury to workers.
