Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] like figure 1 As shown, the circuit principle diagram and working principle diagram of the network pedometer based on bluetooth of the present invention are provided, the shown network pedometer is made up of a three-axis acceleration sensor, a microcontroller and a bluetooth transmission module, and the three-axis acceleration Both the sensor and the bluetooth sending module are connected with the microcontroller. After the user wears the three-axis acceleration sensor, the user's acceleration in three mutually perpendicular directions can be measured, such as Figure 5 As shown, the output accelerations are assumed to be X-axis acceleration, Y-axis acceleration and Z-axis acceleration respectively. The microcontroller collects and calculates the input acceleration data to determine whether the user is effectively taking steps; the microcontro...

The invention relates to a network pedometer based on Bluetooth. The network pedometer comprises a microcontroller, and is characterized in that an input terminal of the microcontroller is connected with a three-axis acceleration sensor, the microcontroller is connected with a Bluetooth sending module, and the network pedometer sends step calculation data to an intelligent terminal through the Bluetooth sending module. A step calculation method provided by the invention comprises the following steps: (a) collecting acceleration magnitudes; (b) selecting a calculating datum axis; (c) enabling digital filtering to be real-time; (d) storing acceleration values; (e) calculating real-time dynamic thresholds; (f) judging that whether acceleration changes are greater than predefined accuracy or not; (g) judging that whether acceleration is greater than the dynamic thresholds or not; (h) judging that whether the slope of an acceleration curve is positive or not. According to the network pedometer and the step calculation method provided by the invention, the axis with the largest average value is selected as the calculating datum axis, so that the accuracy of step forwarding judgment is ensured. By judging that whether the predefined precision, the dynamic thresholds and the slope of the acceleration curve are positive or not, the accuracy of step judgment is ensured.
Description
technical field [0001] The present invention relates to a bluetooth-based network pedometer and a step counting method, more specifically, to a bluetooth-based network pedometer and a pedometer that can effectively and accurately determine the effective steps taken by a user. step method. Background technique [0002] In recent years, pedometers have become increasingly popular, not only to motivate people to challenge themselves, but also to help people build up their physique and lose weight. Bluetooth technology (Bluetooth), as a short-range wireless communication technology, has successfully simplified notebook [0003] The communication between mobile communication terminal devices such as computers, PADs and mobile phones and the Internet makes the data transmission between communication devices and the Internet faster and more efficient, and Bluetooth 4.0 provides a low-cost, low-power, The short-distance wireless communication technology has greatly promoted the wi...
