As shown in Figure 3, the conversion calculation unit 1221 further includes a data input module 12219 connected to the data receiving module 12211, and the data input module 12219 is used to input at least one set of total weight data (including a The total weight of the weight of the rider and the weight of a bicycle, and the weight of the rider and the weight of the bicycle can be modified according to the situation and needs), so the user can input the total weight data by pressing the display unit 11 (touch), However, the total weight data can also be transmitted to the data receiving module 12211 of the conversion calculation unit 1221 in a wireless transmission mode, and a transmission hole (such as TYPE-C) can be set on the shell body 1, in addition to being used for the shell In addition to charging the main body 1, the total weight data can be sent to the conversion calculation unit 1221 through the transmission line to complete the setting.

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

And the moving speed data of this case, as shown in Figure 5, a satellite locator 14 electrically connected to the processing unit 12 is further provided in the housing body 1 (or a satellite positioning function is built in the processing unit 12), The satellite positioning method of the satellite locator 14, in addition to being able to determine the exact position of the bicycle (positioning function), can also use the moving distance and time to calculate the moving speed of the bicycle, and then use the data received by these devices to determine Calculation, energy conversion can be calculated, so the first calculation module 12213 performs kinetic energy calculation based on 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 mass, also is the total weight data, and v is the velocity): Kinetic energy (1) The calculated kinetic energy can be used as the moving energy of the quantified bicycle to do work, and the faster the work done, the higher the kinetic energy will be generated.

And the climbing height data of this case, as shown in the 5th figure, is further provided with a barometric altimeter 15 electrically connected with the processing unit 12 in the housing body 1 (or built-in barometric altitude detection function in the processing unit 12 ), and the barometric altimeter 15 is a device used to measure the altitude. It utilizes the pressure change during climbing to calculate the height of the bicycle climbing. With the parameter of height, gravity and body weight, the gravitational potential energy can be calculated. Therefore, the first The second calculation 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 (wherein m is mass, that is, the total weight data, and g is 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 increase, which can be used as a quantitative parameter of the vertical height in cycling, and then as a judgment index of bicycle strength.

And the riding wind speed data of this case, as shown in Fig. 5, an anemometer 16 electrically connected with the processing unit 12 is further provided in the housing body 1 (or built-in wind speed measurement in the processing unit 12 function), generally a device with a wind speed measuring device 16 is installed on the handlebar 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. Tailwind and headwind while riding is one of the factors that affect power calculations. Therefore, the wind resistance parameter must be added to the wind speed measurement to make the power calculation more accurate. The wind resistance formula is as follows: Wind resistance = (constant 1 x wind speed) + (constant 2 x wind speed squared) (3) Among them, both the constant 1 and the constant 2 are directly proportional to the cross-sectional area, and are related to the streamlined appearance of the bicycle and the human body, and these are all prior art, so they will not be described in detail;

And the third calculation module 12215 can calculate the wind resistance energy according to the following formula, the formula is as follows: Wind resistance energy = wind resistance x travel distance x correction factor 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 AND errors, so it is often multiplied by a correction coefficient to obtain more accurate energy data, and the correction coefficient 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 riding, but since sliding is a common moment during bicycle riding, the rider can be allowed to rest for a while, but at this time Riding does not generate power, so there is obviously a lack of a mechanism to judge whether the bicycle is moving forward, whether it is the rider applying force to make it move forward or the bicycle is moving with inertia, so cadence detection is required for Determine whether the rider is pedaling, collect the data when the rider is pedaling, and calculate the power together.

Therefore, in this case, through an external device 5 with a cadence detection function, or as shown in FIG. Or the processing unit 12 has a built-in cadence detection function) to detect the pedaling state, so as to further control the acquisition source of the moving speed data, the climbing height data and the riding wind speed data, and the acquisition source is as follows: (1) Able to continuously receive moving speed data, climbing height data, riding wind speed data and pedaling state data, and first judge that some time points belong to the pedaling state, and then filter out the moving speed data, climbing height data, riding By wind speed data; (2) Or judge the pedaling state first, and start collecting moving speed data, climbing height data, and riding wind speed data under the pedaling state; if it is judged that there is no pedaling, you can stop collecting the moving speed data and climbing height data , Riding wind speed data.

Finally, use the data obtained from the satellite positioning function, air pressure altitude detection function, wind speed measurement function and cadence detection function to calculate the riding power. Kinetic energy and gravitational potential energy are used as parameters. Kinetic energy expresses the energy at the level Accumulated results, and the gravitational potential energy can be used as the energy parameters of the uphill and downhill sections, combined with the previous wind speed, cadence indicators and time parameters to calculate the riding power. The corresponding formula is as follows: (5)

The above-mentioned time information is the riding time, and the source of the information is 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 for reception. As shown in Figure 4B, the wireless transmission receiving module can be used for wireless transmission (such as blue Buds, infrared or WIFI) to receive time data; (2) Or as shown in Figure 5, a timer 18 electrically connected to the processing unit 12 is additionally provided in the processing unit 12 (the external connection is shown in the figure, but it can also be built in the processing unit 12 Timing function), the conversion calculation unit 1221 can perform timing through the timer 18 to generate record time data.
