Wheelchair curling push rod capable of detecting advancing speed and rotating speed

Abstract

The invention provides a wheelchair curling push rod capable of detecting advancing speed and rotating speed; the wheelchair curling push rod comprises a push rod body and a push rod head connected toone end of the push rod body in a sleeved mode, wherein the push rod head comprises a handle rod and a bayonet sleeve, wherein the handle rod is connected to one end of the rod body of the push rod in a sleeved mode, and the bayonet sleeve is in connection with the handle rod in a single-shaft hinge mode; a shell is arranged at one end of the bayonet sleeve, and the two ends of the shell are encapsulated by a front cover and a rear cover respectively; the shell is internally provided with a motion parameter measurement unit which is used for measuring the advancing speed and the rotating speed when the wheelchair curling leaves from the rod, and the motion parameter measurement unit is used for carrying out data transmission with the outside; and the motion parameter measurement unit comprises a three-axis accelerometer, a three-axis gyroscope, a signal differential amplification circuit, a filtering circuit, a posture resolving module, a data transmission module and a power module which are integrated on a chip module. By means of the push rod, the real-time movement parameters of the push rod head and the curling can be detected when a wheelchair curling athlete performs curling, so that quantitative reference of the state data of the throwing process is provided for wheelchair curling coaches and athletes.

Description

technical field [0001] The invention belongs to the technical field of special devices for sports, and relates to a curling push rod for a wheelchair that can detect the forward speed and the rotational angular velocity when the curling stone is off the rod. Background technique [0002] Wheelchair curling is an important collective competition event in the Winter Games for the Disabled. There are two main differences between wheelchair curling and ordinary curling. The only difference is that ice sweeping is not allowed. The length of the wheelchair curling putter can be adjusted according to the athlete's throwing habits, but the longest cannot exceed 2.45m, and the diameter is about 3cm. The front end of the push rod is provided with a bayonet sleeve for connecting the curling handle, and the rear end of the push rod is provided with a handle for the throwing athlete to grasp, and the bayonet sleeve is connected with the handle rod used for connecting the front end of th...

Problems solved by technology

In addition, the off-rod speed and rotational angular velocity of the curling during the throwing process can only be judged by the athletes' long-term training experience.

[0006] To sum up, so far, it is impossible to detect the off-bar speed and rotational angular velocity of the curling in real time during the throwing process. There is a lack of scientific and effective quantitative analysis of the success and failure of the throwing, which greatly affects the success rate of wheelchair curlers. improve
