The present invention relates to a portable electronic device, and more particularly to a portable electronic device that calculates an energy consumption calculation method.

Due to the busy pace of life and heavy work pressures of modern people, it is easy to cause the formation of many chronic diseases. Therefore, regular and continuous exercise is gradually valued by the Chinese people and is regarded as the basic way to maintain physical and mental health. In general, fast walking or jogging is the easiest and no equipment to exercise, and the number of steps is important for those who want to know how much energy they can consume by walking daily. parameter.

The calculation method of the conventional energy consumption is roughly divided into two types: the first one is to calculate the energy consumed by the human body by the carbon dioxide emitted by the breathing. This method can be accurately calculated but is more troublesome to implement and difficult to be accepted by the public; The calculation is based on the number of steps. The data such as height, weight, and step size are used as important parameters for energy consumption. However, the above physiological parameters cannot accurately calculate the energy consumed by the human body. Because during walking or exercising, it is inevitable to encounter an environment that climbs uphill or downhill, and the energy consumed for walking uphill, the heat consumed for walking on the ground, and the amount of heat consumed for downhill are different. The second method described above does not accurately calculate the energy consumption value.

Therefore, how to design an electronic device that can calculate energy consumption according to the movement or walking environment (such as uphill/downhill or upstairs/down stairs), so that it can accurately calculate the energy without being affected by the motion environment.

Please refer to the first figure, which is a functional diagram of a portable electronic device that calculates the energy consumption of the present embodiment. A portable electronic device, such as a pedometer, a mobile phone, or the like, is an electronic device that can be worn or worn by a user, and includes a sensing unit 10, a processing unit 20, and a display unit 30.

The sensing unit 10 has a gravity sensing unit (G Sensor) 11 and a pressure sensing unit 12. The gravity sensing unit 11 is configured to sense a waveform change amount generated when the user moves the step, and generate a first signal. The pressure sensing unit 12 is configured to detect a height change generated by the user moving each step, thereby generating a second signal.

The processing unit 20 is electrically connected to the sensing unit 10 to receive the first signal and the second signal, and calculates an angle according to the waveform change amount recorded by the first signal and the height change recorded by the second signal. The amount of change, wherein the number of steps the user moves can be calculated based on the amount of waveform change, such as the number of steps taken, or the number of steps in the run. Based on the amount of change in the angle and the number of steps, the processing unit 20 can calculate the energy consumption value of the user in real time, or calculate the corresponding energy consumption value by using a lookup table.

Step (S101): The gravity sensing unit detects a waveform change amount generated when the portable electronic device moves a step with the user.

Step (S102): The pressure sensing unit detects a height change amount generated at each step when the portable electronic device moves with the user.

Step (S103): the processing unit transmits the amount of change of the waveform detected by the gravity sensing unit in the step (S101), and the amount of change in the height detected by the pressure sensing unit in the step (S102), as the upslope or the upslope An environmental change value such as a staircase is used to calculate the angle change, thereby obtaining an angular change amount. In addition, according to the amount of waveform change, the processing unit can calculate the number of steps of the user's movement.

Step (S104): Next, when the user moves a step, if the slope changes, the amount of change in the angle is generated, and when the user moves on different slopes, the energy consumed by the user also changes. Therefore, the processing unit will immediately change the energy consumption calculation method, and use the look-up table or the real-time operation, and according to the angle change amount and the step number, to obtain the corresponding energy consumption value, thereby making the calculation of the energy consumption value data more accurate.

Step (S105): Finally, by using one of the display units of the portable electronic device, a selection interface can be provided to enable the user to select to display the energy consumption value, the number of steps, or the amount of change in the angle on the display unit.

When the user walks on the ground G of different slopes while wearing the portable electronic device, for example, the angle of the gradient of the user walking in the third figure is θ1, or the gradient of the user walking in the fourth figure. The angle is θ2, and the portable electronic device moves in different environments as the user wears, so that the gravity sensing unit in the portable electronic device senses that the user generates when the line is further cut. The amount of waveform change, and the pressure sensing unit thereof can sense the amount of change in height of each step as the slope changes. Therefore, the processing unit in the portable electronic device can calculate an angle change amount and a step number according to the waveform change amount and the height change amount, that is, it can obtain an angle of the gradient that the user walks. And get the number of steps that the user calculates when walking or running.

Since the slope angle of the ground G is different, for example, the angle θ1 of the slope in the third figure is greater than the angle θ2 of the slope in the fourth figure, the energy consumed by the user when walking on the slope in the third figure will be greater than that of walking. The energy consumed by the slope in the four figures. Therefore, the processing unit calculates the energy consumption value of the user based on the above-mentioned angle change amount and the number of steps, and according to a query table or an instant change calculation method. Finally, the calculated energy consumption value is displayed on one of the display units of the portable electronic device for reference by the user, and a selection interface is provided on the display unit for the user to select the reference for walking. Or information such as the number of steps in the run, or the angle of the slope.

In one embodiment, the portable electronic device is mounted on a user riding a bicycle, and the user consumes different energy consumption values when riding the bicycle to climb the slope. One of the bicycle options provided by the portable electronic device can be adjusted, so that when the user steps on the bicycle, the gravity sensing unit in the portable electronic device will detect the waveform change amount, and the pressure sensing unit will The height change amount is detected, and an angle change amount is obtained by the processing unit according to the waveform change amount and the height change amount, wherein the waveform change amount is changed according to each stepping on the bicycle, and thus is processed in this embodiment. The unit calculates the number of times a user has stepped on the bicycle. The processing unit in the portable electronic device queries a special lookup table to calculate a corresponding energy consumption value of the user.

In summary, the portable electronic device for calculating energy consumption in the present embodiment is based on the function of sensing the height change of the pressure sensing unit, and the height change amount and the number of steps of the environment are included in the calculation to dynamically The ground adjustment calculates the energy consumption value of the user and makes the calculation of the energy consumption more precise. For example, the height of the stairs up and down will change the energy consumed by the user; or the user may lose the angle of the user's movement or walking in the third or fourth figure. The energy changes. In this way, the creation can dynamically adjust the calculation formula of energy consumption in real time.
