Method for measuring balance weight and operating parameters of trainer based on reflective type photoelectric sensor

Abstract

The invention relates to a method for measuring balance weight and operating parameters of a trainer based on a reflective type photoelectric sensor. According to the method, reflective type photoelectric sensor measurement units, balance weight block bolts, a calculation unit and a display unit are provided; the lowest reflective type photoelectric sensor measurement unit is aligned to the horizontal center of the lowest balance weight block; each reflective type photoelectric sensor measurement unit is aligned to the horizontal center of each balance weight block from the bottom up in sequence; a part of the measurement units exceed the total height of the balance weight blocks; when the bolts move along with the balance weight blocks, the reflective type photoelectric sensor transmits signals to the calculation unit; the calculation unit solves balance weight, balance weight speed, times and number of groups according to the signals; the calculated data is transmitted to the display unit through a wire or in a wireless manner, and then the data is displayed on the display unit; and therefore, a coach observes the displayed parameters and guides a trainee to do training in real time, so that scientific and targeted training can be enhanced.

Description

technical field [0001] The invention relates to a method for measuring the counterweight and operating parameters of a strength training device, in particular to a method for measuring the counterweight and operating parameters of the training device based on a reflective photoelectric sensor.

[0002] When using strength training equipment for strength training, in order to collect key parameters such as weight, number of sets, times, speed, and training rhythm during training, it is mainly through the technology related to the weight of the strength training device or operating parameters, such as the use of mechanical switches to detect The technology of counterweight, the technology of using rope to detect the movement state of counterweight and the technology of detecting the movement speed of counterweight through angle sensor, but these technologies all have a common shortcoming: (1) the weight of counterweight and the movement of counterweight cannot be collected at the same time. Speed, frequency, number of groups and other parameters; (2) complex structure, high cost, and cumbersome installation; the invention patent with application number 201210492646.7 "Method for Measuring Counterweight and Operating Parameters of Strength Training Device Based on Infrared Sensing Technology", its technology The scheme is: the infrared data acquisition sensor unit collects the information of the position of the heavy block plug through a collection unit composed of several pairs of infrared light-emitting diodes and infrared receiving diodes; The last section is between a pair of infrared light-emitting diodes and infrared receiving diodes, and the infrared receiving diodes will generate an interrupt signal; the bottom acquisition unit is aligned with the horizontal center of the bottom weight block; from bottom to top, each acquisition unit is aligned At the horizontal center of each weight, some acquisition units exceed the total height of the weight; when the latch moves with the weight, the MCU computing unit on the infrared data sensor unit calculates the counterweight and weight according to the signals sent by these acquisition units. Weight speed, reps and sets

Since this technical solution requires that the infrared receiving tube and the infrared emitting tube must be aligned one by one, the production and installation requirements are relatively high in practical applications, and the implementation cost is relatively high.
