Abstract

The invention relates to a radio detector for detecting the stepping force of bikes, which belongs to a detector for detecting the stepping force of bikes. The detector comprises pedals and circuits; wherein, the pedals can be fixed and connected with a beam by screws. A pressure sensor is fixed and connected with the beam which is fixed and connected with a bearing sleeve. The bearing sleeve is fixed and connected with a stepping axle of a bike. Circuit boards are embedded in the pedals. The circuit part includes that an independent power supply, the pressure sensor, an amplifying circuit, an A / D converter circuit, a radio transmitting and receiving module and a single chip computer are connected with a liquid crystal displays and a memory which is connected with a dual-port RAM. The invention has the advantages that sensors are arranged on the pedals and directly detect the force; circuit boards and sensors are designed to be integrated; and the range of using objects is very wide.

Description

technical field [0001] The invention relates to an electromechanical detection device, in particular to a detection device applied in the field of bicycle pedaling force detection. Background technique [0002] Initially, the detection of bicycle pedaling force was mainly obtained through photography, video and video and image analysis software to obtain human kinematic parameters, and combined with the three-dimensional force plate under experimental conditions, the corresponding power was obtained through image analysis using synchronous technology. Kinematics and kinematics parameters, analysis and comparison from two aspects of kinematics and dynamics, to explore the principles and laws of sports technology, to provide a basis for evaluating the rationality of movement technology, designing new training methods, improving sports technology movements, and improving sports performance. Theoretical basis, based on which the athletes are guided and trained; rather than the d...
