In sports, rope skipping is one of the physical exercise items that is accepted by many people and is widely used in rope skipping sports competitions and rope skipping sports exams in families, health sports counseling centers, schools and other enterprises and institutions. Compared with other sports auxiliary equipment, the biggest advantage of skipping rope is that it is easy to store, because it is small in size, light in weight, does not occupy space, and can be used at any time. The existing skipping ropes on the market generally do not have a counting function and need to be counted manually. However, in many cases, manual counting will cause unfairness at the competition or examination site. Therefore, skipping rope closely follows the pace of the intelligent development of electronic products and becomes a skipping rope that can be automatically counted.
The realization of this electronic counting rope skipping technology includes the following elements: two handles and a rope connecting the two handles. The handle is a structure with a cavity formed by the upper cover and the lower cover interlocking with each other. One of the handles is encapsulated with a circuit board and a magnetic encoder connected to the battery, and the other is the opening of the cavity for placing the battery in the handle. The battery back cover is hinged, and the two ends of the rope pass through the connecting shaft and are fastened by fixing rope screws to achieve fixation. The magnetic encoder includes a magnet turntable, a magnetoresistive sensor and a signal processing circuit. The magnet turntable is placed in the handle and the center of the magnet turntable is provided with a waist-shaped hole. The end of the connecting shaft is waist-shaped and inserted into the waist-shaped magnet turntable. In the hole, a magnetoresistive sensor is installed inside the handle at a position corresponding to one side of the magnet turntable, and the magnetoresistive sensor is connected to the signal processing circuit in the circuit board. The surface of the upper cover is provided with a way out for the LCD screen and the buttons, and the LCD screen and the buttons are electrically connected to the circuit board.
The electronic counting rope skipping circuit board function developed by Sanjing mainly has two modes: ①forward counting mode; ②one-minute countdown counting mode; ③automatic screen rest. The forward counting is set as the default mode. The one-minute countdown mode is in the default mode. Double-click to enter this mode, and then click to start the countdown. If the time is up, an alarm will be issued automatically. Speaking of this, I believe that many people may ask questions, is this skipping count inaccurate? What I can safely tell you here is that the electronic counting skipping rope uses upgraded electronic chips, so there are generally no problems such as inaccurate counting.
