The utility model discloses a kind of cancer proton heavy ion radiotherapy positioning auxiliary equipment, it is related to positioning auxiliary equipment technical field, including: base, first hydraulic cavity is equipped in its inside middle part, liftable hydraulic disc is connectable in the first hydraulic cavity;Supporting rod, its bottom end is fixed to the hydraulic disc top end, top end is connected with the load plate for carrying patient;Symmetrically set in the side tank of base both sides, each side tank is equipped with the buffer hydraulic cavity being communicated with the first hydraulic cavity, the buffer hydraulic cavity top is connected with multiple second hydraulic cavities;The utility model patient is more, the pressure that hydraulic disc bears is greater, the pressure difference in the first hydraulic cavity is greater, the force that is stronger to second hydraulic cavity push piston and positioning rod is transmitted, the clamping force of positioning rod to patient is greater;This characteristic makes equipment can adapt to patient of different weight, especially applicable to the generally larger weight American population, guarantee the stability and reliability of positioning.

The utility model relates to the technical field of whole-body safety belts, in particular to a whole-body safety belt with an anti-static function, which comprises a waist bandage, a chest bandage and an extension ring, the chest bandage is arranged above the waist bandage, the bottom of the chest bandage is connected with the top of the waist bandage in a sewing mode, and the extension ring is arranged on the waist bandage. A fixing bandage is arranged at the bottom of the waist bandage, a leg bandage is arranged at the bottom of the fixing bandage, the interior of the leg bandage is connected with the extension ring in an embedded mode, fluff on the bandage is prevented from directly rubbing a user to generate static electricity, meanwhile, a static bracelet is arranged, the static bracelet is fixed to the wrist of the user, and therefore the static electricity can be effectively prevented from being generated. The electrostatic bracelet is in contact with the skin of a user, so that the human body and the whole-body safety belt are at the same potential, the potential difference between the human body and the equipment is eliminated, electrostatic discharge is prevented, static electricity generated after long-term use is effectively prevented, and the safety of the device is embodied.

This invention discloses a method for assessing driver's road driving ability based on big data, comprising: multi-dimensional collection of driving behavior data from instructors and trainees; setting standard event thresholds to identify and distinguish normal and abnormal behaviors; screening indicators in which the instructor's performance is significantly better than the trainee's during the interaction process, and quantifying these process-oriented behavioral indicators using the standard event thresholds; determining optimal weights with the instructor's score being better than the trainee's score as the optimization objective; and after determining the optimal weights for each behavioral indicator, calculating the total score for each item using weighted averages to achieve the assessment of the driver's road driving ability. This invention provides an effective tool for driver training through a scientific, objective, and comprehensive evaluation system, helping to improve trainees' driving skills and safety awareness, enhance the quality of training and testing, and ultimately improve road traffic safety.

This invention relates to the field of AGV control technology, and more particularly to an AGV safety control method based on ARM. This invention continuously collects the force values ​​at several load points on the load plane corresponding to different types of loads during AGV movement, and extracts specific behavioral features by combining historical movement characteristics, thereby constructing a set of historical specific behavioral features strongly correlated with the type of load. When a new control command is received, the relevant set of historical specific behavioral features is invoked to determine whether intervention is needed, and the control command is optimized, such as adjusting the moving speed or braking force, thereby improving the safety and operational reliability of the AGV under complex working conditions.
