Power is data on changes in riding intensity over time; (8) An output module 12218 is connected to the fifth computing module 12217, and the output module 12218 is used to display the riding power on the In addition to riding power, the display unit 11 of the housing body 1 can also be connected to the data receiving module 12211 to display moving speed data, climbing height data or/and riding wind speed data.

As shown in Figure 3, the conversion calculation unit 1221 further includes a data input module 12219 connected to the data receiving module 12211. The data input module 12219 is used to input at least one set of total weight data (including a rider The total weight of the rider's weight and the weight of a bicycle, and the rider's weight and the bicycle weight 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 type). However, the total weight data can also be transmitted to the data receiving module 12211 of the conversion calculation unit 1221 through wireless transmission, and a transmission hole (such as TYPE-C) can be opened on the housing body 1. In addition to being used to adjust the housing In addition to charging the main body 1, it can also transmit the total weight data 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 devices with satellite positioning function, air pressure altitude detection function or/and wind speed detection function. Detected by the external device 5, in order to receive the data detected by the external device 5, as shown in Figure 4B, a wireless transmission receiver 13 (or a wireless transmission receiver 13 within the processing unit 12) is connected to the processing unit 12. Built-in wireless transmission and reception functions, such as Bluetooth, infrared or WIFI), in order to receive data detected by the external device 5.

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 of this case, as shown in Figure 5, a satellite locator 14 electrically connected to the processing unit 12 is provided in the housing body 1 (or a satellite positioning function is built into the processing unit 12). 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 collected by these devices to calculate the moving speed of the bicycle. By calculating, the energy conversion can be calculated. Therefore, the first calculation module 12213 performs kinetic energy calculation based on the total weight data and the moving speed data to obtain the moving horizontal energy data. The kinetic energy calculation formula is as follows (where m is the mass, also is the total weight data, and v is the speed):

The calculated kinetic energy can be used to quantify the movement energy of the bicycle. The faster the work is done, the higher the kinetic energy will be generated.

As for the climbing height data of this case, as shown in Figure 5, a barometric height sensor 15 electrically connected to the processing unit 12 is provided in the housing body 1 (or the processing unit 12 has a built-in barometric height detection function. ), and the air pressure altimeter 15 is a device used to measure altitude. The pressure change during climbing is used to calculate the height of the bicycle climbing. With the height parameter, gravity, and weight, the gravitational potential energy can be calculated. Therefore, the third The second calculation module 12214 performs gravity potential energy calculation on the total weight data and the climbing height data to obtain the climbing vertical energy data, and the gravity potential energy calculation formula is as follows (where m is the mass, which is the total weight data, and g is Acceleration of gravity, and h is height): gravitational potential energy = mgh (2) As the climbing height of the bicycle slowly increases, the calculated gravitational potential energy will become larger and can be used as a quantitative parameter of the vertical height in bicycle motion. It is then used as an indicator of bicycle strength.

As for the riding wind speed data in this case, as shown in Figure 5, a wind speed measuring device 16 electrically connected to the processing unit 12 is further provided in the housing body 1 (or a wind speed measuring device is built-in in the processing unit 12 (measuring function), generally a device with a wind speed measuring device 16 is installed on the handlebar of a bicycle in order to measure the frontal wind speed while riding. This wind speed can be calculated to obtain the wind resistance value. The tailwind and headwind when riding are one of the factors that affect the power calculation. Therefore, the wind resistance parameter must be added to the measurement of wind speed to make the power calculation more accurate. The wind resistance formula is as follows: wind resistance = (constant 1x wind speed) + (constant 2x wind speed squared) (3) Among them, the constant 1 and The constant 2 is proportional to the cross-sectional area and is related to the streamlined appearance of the bicycle and the human body. These are all existing technologies, so they will not be described in detail. The third calculation module 12215 can calculate the wind resistance according to the following formula. Energy, the formula is as follows: Wind resistance energy = Wind resistance Energy (wind resistance) multiplied by displacement (travel distance) is energy. However, due to environmental errors, a correction coefficient is often multiplied to obtain more accurate energy data. 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 while riding. However, since sliding is a common moment while riding a bicycle, the rider can take a break, but at this time Riding does not generate power, so there is obviously a lack of a mechanism to determine whether the rider is applying force to move the bicycle forward or the bicycle is displacing due to inertia when the bicycle is traveling. Therefore, cadence detection is required. Determine whether the rider is pedaling, and collect the data when pedaling to calculate the power.

Therefore, in this case, through an external device 5 with a cadence detection function, or as shown in Figure 5, a cadence detector 17 electrically connected to the processing unit 12 is provided in the housing body 1 (Or a cadence detection function is built-in in the processing unit 12) 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) It can continuously receive moving speed data, climbing height data, riding wind speed data and pedaling status data, and first determine that some time points belong to the pedaling status, and then filter out the moving speed data, climbing height data, riding status data in these pedaling statuses Riding wind speed data; (2) Or synchronize the pedaling status judgment first, 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, the moving speed data can be stopped. , climbing height data, riding wind speed data.

Finally, the data obtained from the satellite positioning function, air pressure altitude detection function, wind speed measurement function and cadence detection function are used to calculate the riding power, taking kinetic energy and gravitational potential energy as the parameters, where kinetic energy expresses horizontal energy. Cumulative results, and gravitational potential energy can be used as the energy parameter of the uphill and downhill sections. Combined with the previous wind speed and cadence indicators and the time parameter, the riding power can be calculated. The corresponding formula is as follows:

The above time data is the riding time, and its data sources are as follows: (1) After being measured by an external device, it is 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 , time data can be received through wireless transmission and reception modules through wireless transmission (such as Bluetooth, infrared or WIFI); (2) or as shown in Figure 5, the processing unit 12 is additionally provided with a processing unit 12 electrically connected timer 18 (shown as an external connection in the figure, but it can also be built into the processing unit 12 time function), the conversion calculation unit 1221 can perform timing through the timer 18 to generate recorded time data.
