The concrete advantage of the present invention is the following aspects:
1. Design of Sensor on pedal, is the direct detection to power.
Directly detection does not need by photography, video recording and shadow, obtains detection power size indirectly as resolving software processes etc., thereby has satisfied the real-time requirement that detects.To the direct detection of power, make the Data Dynamic performance strengthen, reliability improves.
2. the integrated design of power testing circuit plate and sensor.
Integrated design has solved raw data and has been easy to cause because of environmental factor inaccurate problem, and this system bulk is little, in light weight, antijamming capability is strong, system has high reliability, vibrationproof, waterproof and dustproof, can improve trainer's adaptability greatly, can not cause the interruption trained because of environmental factor.
3. on the data transmission wireless transmission and receiving system.
Wireless transmission and receiving system have solved wire transmission because of data line various and have caused the inconvenience of training athlete, and wireless data receives the emission unification, and in real time, accurately, antijamming capability is strong; Frequency stability is fabulous, and the design of low emissive power, high receiving sensitivity can directly connect the CPU serial ports and use as 8031, also can connect computing machine RS232 interface, and software programming is very convenient.Data can online and processed offline, draw the family curve of dynamic parameter, explore the principle and the characteristics of motion of Motion Technology, for the new training tool of rationality, the design of estimating stroking technique, improve the Motion Technology action, improve sports achievement theory and data foundation are provided, in view of the above the sportsman is instructed and trains, improve training quality.
Receiving system shows the size of the power of scrunching in real time with LCD, makes the very hommization of this instrument.The sportsman can see the size of the power that oneself scrunches in real time, can regulate stepping frequency and scrunch amplitude according to the condition of oneself, thereby allow oneself ride more convenient, more laborsaving, faster, obtains better achievement.
4. extensive at object range.Not merely being the sportsman, also can be body-building personages such as teenager or the elderly.
