The invention provides an unknown environment route planning method of an underwater cleaning robot, which is a self-adaptive learning fuzzy control method for planning a track in an unknown environment. The method is characterized in that: by simulating the route planning thought, obstacle avoiding through and intelligent thoughts for making a decision for determining the priority of quick planning and obstacle avoiding, three different sub fuzzy controllers are put forward correspondingly for solving three kinds of problems. Meanwhile, according to the estimation of the movement results of a controlled robot, the rule base of the fuzzy controller is modified correspondingly to make the fuzzy controller can handle more complex external disturbance and effectively solve the problem of U-shaped obstacles and symmetric obstacles, so that the robot can complete a planned task and arrive at a destination in a more complex environment. The method eliminates the uncertainty influences of an underground complex environmental factor on the route planning of the robot, improves the movement safety of the robot and enables the robot to well adapt to the complex underground industrial environment.

The invention relates to a full closed-loop control method for multi-shaft linked dynamic correction of interpolation positions. The full closed-loop control method for multi-shaft linked dynamic correction of the interpolation positions comprises adjusting command positions of shafts on a first command position coordinate according to collected deviation between actual positions of the shafts and a motor; performing projection of adjusted command position vectors of the shafts on a machined track, obtaining a projection length and confirming corrected command positions; stopping adjusting when a full closed-loop condition is satisfied; performing speed connection processing on a movement segment and a next movement segment when a program segment is in parallel connection and provided with follow-up movement segments; not adjusting the interpolation positions until interpolation of the current movement segment is not achieved if the full closed-loop control condition is not satisfied and enabling the actual positions of the shafts to be moved to the command positions through a PID (Proportion Integration Differentiation) control algorithm within the positioning duration which is provided through a system. The full closed-loop control method for multi-shaft linked dynamic correction of the interpolation positions has the advantages of satisfying the multi-shaft linked profile accuracy, the positioning accuracy and the repositioning accuracy, meanwhile guaranteeing stabile operation of a servo motor, guaranteeing workpiece machining accuracy and prolonging the service life of machine tools.

The invention is applicable to the intelligent wearing technical field, and provides a method, device and equipment for reminding a motion state of wearable equipment, and a storage medium. The methodincludes the steps: detecting whether a user with the wearable equipment is in a motion state by an attitude sensor associated with the wearable equipment; if the user is in a motion state, monitoring the motion mode and the motion amount of the user with the wearable equipment by a preset sensor, judging whether the motion amount of the user with the wearable equipment is overloaded, and judgingwhether the motion mode of the user with the wearable equipment is standardized; and when the motion mode of the user with the wearable equipment is not standardized or the motion amount of the userwith the wearable equipment is overloaded, reminding the user with the wearable equipment of the motion state of the user with the wearable equipment by a preset first reminding method. By monitoringthe various own motion situations of the user, different users are reminded targetedly to increase the motion security of the users.

The invention relates to the field of preparation for artificial turf and discloses a wear-resistance artificial turf capable of being cooled and a preparation method thereof. The preparation method comprises the following steps that (1) nano titanium dioxide, gas-phase white carbon black, nano lithopone and nano talcum powder are ground and mixed to prepare a thermal insulation powder material; (2) the thermal insulation powder material, a coupling agent and glass powder are evenly dispersed to prepare composite powder; (3) the composite powder is heated, subjected to spinneret, collected byhydrophilic silicon dioxide sol and then dried to obtain a composite filler; (4) the functional composite filler, polyolefin resin, color master batches and a dispersion agent are mixed, extruded anddrafted to prepare an artificial grass yarn fiber, and a base cloth is selected, tufted, gummed, dried and untwisted to prepare the artificial turf. The prepared artificial turf has good hydrophilic performance and water retention performance, the surface temperature can be obviously lowered, the artificial turf has good mechanical properties and wear-resistant properties, and the service life ofthe artificial turf is prolonged.

The invention relates to an impact-resistant protective seamless wrestling dress. The impact-resistant protective seamless wrestling dress is siamesed sportswear woven by a Santoni SM8-TOP2S-model seamless knitting machine. A first interval stitch is adopted on the waist and abdomen portion and the back portion of the wrestling dress, a second interval stitch is adopted on the shoulder portions, a front piece, the hip portion and the thigh portions, an eyelet stitch is adopted on body piece segmenting decoration threads, a close stitch is adopted on the crotch portion, and a tuck stitch is adopted on closing of a neck, sleeve openings and leg openings. The impact-resistant protective seamless wrestling dress is the sportswear integrating functionality with comfort; stitch structures highest in impact resistance are compatibly adopted on the parts, most susceptible to impact damage, of a human body, impact perforation of the waist and abdomen portion and the back portion of the wrestling dress is larger than 22 Joules, and impact resistance of the wrestling dress is considerably higher than that of common sportswear; the stitches good in moisture absorption and sweat release performance are compatibly adopted on the parts, insusceptible to damage, of the human body, so that wearing comfort of the wrestling dress is improved.

The invention provides a breathing lamp switching method and device in a motion state. The method comprises steps that S101, present motion frequency is acquired; S102, a present motion state is determined; and S103, a breathing lamp state is switched according to the motion state. The method is advantaged in that the breathing lamp is switched according to different present motion states of a user, the breathing lamp can be in a high brightness state to prompt a vehicle to avoid pedestrian when the user is in motion, and motion safety of the user is improved.
