Problems solved by technology

Multiple Hall sensors not only increase the cost of the counter system in the electronic counting skipping rope, but also have relatively high requirements for the bar magnet. If the magnetism of the bar magnet is too large or too small, the counting will be inaccurate

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the examples, the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0034]Referring to Fig. 1, a linear Hall sensor type counting module 6 includes a counting control unit 2 and a linear Hall sensor 3, the counting control unit 2 is connected with the linear Hall sensor 3, and the linear Hall sensor 3 is used to set The corresponding position of the sensing end of the joint 5, and the sensing end of the rotary joint 5 is provided with a bar magnet 4, and the N and S magnetic poles of the bar magnet 4 are arranged in the same direction as the direction of rotation of the bar magnet 4, so that When the rotary joint 5 rotates, the strip magnetic block 4 approaches or moves away from the linear Hall sensor 3, and the linear Hall sensor 3 converts the magnetic signal into a linear electrical signal based on the ch...

Abstract

The invention discloses a linear Hall sensor type counting module, which comprises a counting control unit and a linear Hall sensor, the counting control unit is connected with the linear Hall sensor, and the linear Hall sensor is used for setting in a rotating The corresponding position of the induction end of the joint, and the induction end of the rotary joint is provided with a bar-shaped magnetic block, and the magnetic pole setting direction of the bar-shaped magnetic block is consistent with the rotation direction of the bar-shaped magnetic block; it is also proposed and The corresponding counter and skipping rope only need a linear Hall sensor and a magnetic block. On the one hand, it reduces the cost of the counter system. On the other hand, it can distinguish the rotation direction of the rotary joint, so that the counting is accurate, and it will not cause missing counts or Count more.

Description

technical field [0001] The invention relates to the field of counting test, in particular to a linear hall sensor type counting module, a corresponding counter and a skipping rope. Background technique [0002] Rope skipping is one of the sports that people often engage in, and rope skipping has been included in the compulsory physical education courses of primary schools, which has a particularly important position. Whether it is in the rope skipping competition or daily exercise, it is necessary to count, so as to record the competition results according to the obtained values, or use the obtained values ​​as sports indicators to evaluate people's physical fitness. Existing skipping ropes are generally divided into traditional skipping ropes and electronic counting skipping ropes. Traditional skipping ropes are counted manually; electronic counting skipping ropes are mostly counted based on switch sensors, at least one Hall sensor is required, and when it is necessary to j...
