As shown in Figure 4A, the moving speed data, climbing height data and riding wind speed data in the pedaling state in this case are obtained through one or more satellite positioning functions, air pressure altitude detection functions or/and wind speed detection functions. In order to receive the data detected by the external device 5, and as shown in FIG. 4B, a wireless transmission receiver 13 (or in the processing unit 12) is connected to the processing unit 12. Built-in wireless transmission and reception function, such as bluetooth, infrared or WIFI), in order to receive the data detected by the external device 5.

(1) 其中運算出來的動能可以作為量化自行車的移動能作功，作功的速度越快則會產生更高的動能。 As for the moving speed data in this case, as shown in FIG. 5, a satellite locator 14 electrically connected to the processing unit 12 is further provided in the housing body 1 (or the processing unit 12 has a built-in satellite positioning function), The satellite positioning method of the satellite locator 14 can not only be used to determine the exact position of the bicycle (positioning function), but also can use the moving distance and time to calculate the moving speed of the bicycle, and then use the data received by these devices to calculate The energy conversion can be calculated by calculating, so the first calculation module 12213 performs kinetic energy calculation according to the total weight data and the moving speed data to obtain the moving level energy data, and the kinetic energy calculation formula is as follows (where m is the mass, also is the sum weight data, and v is the velocity): kinetic energy

(1) The calculated kinetic energy can be used to quantify the movement energy of the bicycle as work, and the faster the work is done, the higher the kinetic energy will be.

(2) 而隨著自行車的攀登高度慢慢提升，計算出來的重力位能就會越大可做為自行車運動中垂直高度的量化參數，進而做為自行車強度的判斷指標。 As for the climbing height data in this case, as shown in FIG. 5 , an air pressure altimeter 15 electrically connected to the processing unit 12 is further provided in the housing body 1 (or the air pressure height detection function is built in the processing unit 12 ). ), and the barometric altimeter 15 is a device used to measure the altitude. It uses the pressure change during climbing to calculate the climbing height of the bicycle. With the parameter of height, gravity and weight, the gravitational potential energy can be calculated. Therefore, the first The second operation module 12214 performs gravitational potential energy calculation on the total weight data and the climbing height data to obtain the climbing vertical energy data, and the gravitational potential energy calculation formula is as follows (where m is the mass, that is, the total weight data, and g is the Gravitational acceleration, and h is height): Gravitational potential energy

(2) As the climbing height of the bicycle gradually increases, the calculated gravitational potential energy will be larger.

As for the riding wind speed data in this case, as shown in FIG. 5 , an wind speed measuring device 16 (or a built-in wind speed measuring device 16 in the processing unit 12 is further arranged in the housing body 1 ) which is electrically connected to the processing unit 12 . function), a device with an wind speed measuring device 16 is generally installed on the handlebars of the bicycle, so as to measure the frontal wind speed when riding, and the wind speed can be calculated to obtain the wind resistance value. The tailwind and headwind when riding is one of the factors that affects the power calculation. Therefore, the parameters of wind resistance must be added to the measurement of wind speed to make the power calculation more accurate. The formula of wind resistance is as follows: Wind resistance = (constant 1 x wind speed) + (constant 2 x wind speed squared) (3) Among them, the constant 1 and the constant 2 are both proportional to the cross-sectional area, and are related to the streamlined shape of the bicycle and the human body, and these are all in the prior art, so no additional description is required;

The third computing module 12215 can calculate the wind resistance energy according to the following formula, and the formula is as follows: Wind resistance energy = wind resistance x travel distance x correction factor (4) Among them, the travel distance can be obtained through the satellite locator 14, and the wind resistance energy is the force multiplied by the displacement, which can be converted into work, because the force (wind resistance) multiplied by the displacement (travel distance) is energy, but due to the environment There will be some errors, so it is often multiplied by a correction factor to obtain more accurate energy data, and the correction factor can be adjusted according to the situation.

As mentioned above, combining the above kinetic energy, gravitational potential energy, and wind resistance can quantify the energy generated during the ride, but since gliding is a common moment in a bicycle ride, it is possible to give the rider a little rest, but this time Riding does not generate power, so there is obviously a lack of a mechanism to judge whether the bicycle is moving, whether it is the rider applying force to make it move forward, or the bicycle is shifting due to inertia. Therefore, cadence detection is required to be used. Determine whether the rider is pedaling, collect the data when pedaling and calculate the power.

Therefore, in this case, an external device 5 with cadence detection function is used, or as shown in FIG. 5, a cadence detector 17 ( Alternatively, the processing unit 12 has a built-in cadence detection function) to detect the pedaling state, so as to control the acquisition source of the moving speed data, the climbing height data and the riding wind speed data, and the acquisition sources are as follows: (1) Can continuously receive data on movement speed, climbing height, riding wind speed and pedaling state data, and first determine that some time points belong to the pedaling state, and then filter out the moving speed data, climbing height data, riding state data in these pedaling states wind speed information; (2) Or firstly judge the pedaling state synchronously, and start collecting moving speed data, climbing height data, and riding wind speed data in the pedaling state; if it is judged that there is no pedaling, you can stop capturing the moving speed data and climbing height data. , Riding wind speed data.

(5) Finally, use the data obtained by the satellite positioning function, the air pressure and altitude detection function, the wind speed measurement function and the cadence detection function to calculate the riding power, and use the kinetic energy and gravity potential energy as the parameters, where the kinetic energy expresses the horizontal energy. Accumulated performance, and the gravity potential energy can be used as the energy parameter of the uphill and downhill sections, combined with the previous wind speed and cadence index plus the time parameter to calculate the riding power, the corresponding formula is as follows:

(5)

The above time information is the riding time, and its sources are as follows: (1) After being measured by an external device, it can be sent to the data receiving module 12211 of the conversion calculation unit 1221 of the processing unit 12 to receive, as shown in Figure 4B, it can be transmitted wirelessly through the wireless transmission receiving module (such as blue Bud, infrared or WIFI) to receive time data; (2) Or as shown in FIG. 5 , the processing unit 12 is additionally provided with a timer 18 that is electrically connected to the processing unit 12 (shown in the figure as an external connection, but it can also be built into the processing unit 12 ) timing function), the conversion calculation unit 1221 can perform timing through the timer 18 to generate recorded time data.

When compared with other conventional technologies, the bicycle power monitoring device provided by this creation has the following advantages: (1) This creation can obtain the work and power of the bicycle by collecting the position, height change, and wind resistance of the bicycle, and using the data collected above to perform calculations. (2) This creation is very easy to install. It does not require complicated tools to disassemble the large plate or pedal to perform measurement.
