Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a counting assembly for sit-up monitoring based on wireless networking comprises a host computer 1 and a plurality of groups of slaves 2, wherein the host computer 1 and the slaves 2 are both connected with a binding belt 12, so that the counting assembly is convenient to wear and monitor, a battery 6, a single chip microcomputer 5, a wireless networking module 8 connected with the single chip microcomputer 5 and an address selection module 7 are arranged in the host computer 1 and the slaves 2, the host computer 1 and the slaves 2 are in communication connection through the wireless networking module 8, independent addresses can be set for each slave 2 by utilizing the address selection module 7, the host computer 1 can collect data of each slave 2 in a polling mode, the wireless networking is realized by an NRF24L01, one-to-many wireless networking is realized by modifying the module address through software, and a large number of slaves 2 can be connected with the host computer 1 and transmit the number of movements in real time;

the slave machine 2 is also provided with an angle detection module 3 connected with the singlechip 5, and whether the student finish actions are standard is judged by detecting the change state of the angle;

the host computer 1 is also provided with a button component connected with the singlechip 5, a Bluetooth module 9 and an OLED screen 10, the mode can be selected by utilizing the button component 11, the timing time can be regulated, statistical data can be displayed by utilizing the OLED screen 10, and finally, the statistical data can be transmitted to a mobile phone through the Bluetooth module 9 for later data processing and storage.

In order to accurately monitor the action change of the students, preferably, the slave machine 2 is also provided with a Hall sensor 4 connected with a singlechip 5, the magnet is bound on the legs of the students, the Hall sensor 4 can be triggered only when the students sit completely, and the motion counting is completed by combining the angle detection module 3.

For facilitating the key adjustment, the button assembly preferably comprises a timing up key 11.1, a timing down key 11.2, a transmission record key 11.3 and a start key 11.4, and the independent keys are designed to be selectively adjusted as required.
