[0030] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0031] Example 1: Reference Figure 1-Figure 3 As shown, a meter 300 capable of measuring the actual temperature of the meter includes: The first temperature sensor 110 collects the temperature inside the code table 300, which is recorded as the first temperature T1; The second temperature sensor 120 is disposed in the heat-insulating space 310 in the computer 300 and collects the temperature in the heat-insulating space 310 as a second temperature T2; A speed sensor, recording the running speed of the stopwatch 300; The ultraviolet light sensor 130 determines whether the code meter 300 is in a sun exposure state, and collects the sun exposure time and the non-sun exposure time; A calculation module is used to receive the first temperature T1, the second temperature T2, the sunshine time h, the non-sunlight time h0 and the running speed V, and is also used to calculate the actual temperature difference according to the first temperature T1, the second temperature T2, the sunshine time h, the non-sunlight time h0 and the running speed V, and obtain the actual temperature using the actual temperature difference and the second temperature; the calculation formula of the actual temperature is: Actual temperature = second temperature - actual temperature difference.

[0032] In this real-time example, the first temperature sensor 110 is arranged inside the code table 300, and its setting position is similar to the setting position of the temperature sensor inside the code table 300 in the prior art; when sunlight directly shines on the code table 300, the first temperature T1 collected by the first temperature sensor 110 is usually greater than the actual ambient temperature.

[0033] A heat-insulating space 310 is provided in the code computer 300, and the temperature in the heat-insulating space 310 is collected by the second temperature sensor 120, which is recorded as the second temperature T2; Reference Figure 1-Figure 3 As shown, in order to overcome the problem of inaccurate temperature collection data caused by a small greenhouse formed inside the code table 300 when sunlight shines on the code table 300, this embodiment sets an insulating space 310 inside the code table 300, and the insulating space 310 is used to place the second temperature sensor 120.

[0034] The heat-insulating space 310 is located on the side of the code computer 300 that faces away from the sunlight during riding, specifically, is set on the back of the code computer 300, which can effectively avoid direct sunlight and shield interference from external heat sources; in addition, the heat-insulating space 310 is set on the side away from the forward direction of riding, which can effectively reduce the cooling of the wind resistance on the windward side of the code computer 300 during riding.

[0035] The heat-insulating space 310 is an independent space, so that the second temperature sensor 120 has no direct contact with other components of the computer 300, and the influence of external factors on its temperature measurement is further reduced.

[0036] The interior of the heat-insulating space 310 is provided with heat-insulating materials, which can effectively prevent the temperature hysteresis caused by the material characteristics from affecting the sensor temperature acquisition after the housing of the code computer 300 is over-exposed to the sun, thereby improving the response rate of the temperature change.

[0037] The bottom of the heat-insulating space 310, i.e., the portion where the heat-insulating space 310 contacts the back shell of the code computer 300, is connected using a cover plate 320; the cover plate 320 uses a waterproof and breathable membrane 321 to reduce the introduction of other interference factors while measuring external temperature parameters.

[0038] During the installation of the second temperature sensor 120, a flexible circuit board is used to peel the second temperature sensor 120 from the PCB board, leaving only the circuit connected to the PCBA, and the flexible circuit board is placed in the insulation space 310; and the flexible circuit board is sealed at the place where it passes through the shell, effectively isolating the temperature hysteresis caused by the penetration of high-temperature gas in the internal cavity of the code table 300.

[0039] The ultraviolet light sensor 130 is disposed on the surface of the cycling computer 300 facing sunlight.

[0040] Specifically, the ultraviolet light sensor 130 is arranged on the cover 320 above the code table 300; it can measure whether the current code table 300 is in a sunlight state; when it is collected that the code table 300 is in a sunlight state, it starts to record the continued sunlight duration h; then the sunlight duration h of the previous sunlight stage is cleared; similarly, when it is collected that the code table 300 is in a non-sunlight state, it starts to record the continuous non-sunlight duration h0; then the non-sunlight duration h0 of the previous non-sunlight stage is cleared.

[0041] The running speed V generated by the code table 300 following the riding motion can be obtained through the GNSS chip 140. In the process of following the riding motion, different running speeds V of the code table 300 will also affect the temperature measurement of the first temperature sensor 110 and the second temperature sensor 120. Therefore, the influence factor of the running speed V will also be considered in the subsequent actual temperature calculation process.

[0042] Reference Figure 4 As shown, considering the entire operation process of the code table 300, according to the relationship between the sunlight parameters and the first temperature T1 and the second temperature T2, the operation process of the code table 300 can be divided into the following states: State S1: the code computer 300 is in the sunlight heating stage or the non-sunlight cooling stage. In this state, T2<T1; and the sunlight duration h>0.

[0043] If the code table 300 is in the sun-heating stage, the non-sunlight duration h0=0; if the code table 300 is in the non-sunlight cooling stage, the non-sunlight duration h0>0.

[0044] The state S1 can be recorded as the sun-exposed state of the cycling computer 300 .

[0045] State S2: when the code table 300 is in the sun exposure state, the second temperature T2 continues to rise to the first temperature T1, that is, T2=T1; at this time, the actual temperature difference between the first temperature T1 and the second temperature T2 remains unchanged; indicating that the code table 300 is in the sun exposure state at this time.

[0046] The state S2 can be recorded as the sun-proof state of the cycling computer 300 .

[0047] State S3: When the code table 300 is in a non-sunlight state, the first temperature T1 and the second temperature T2 both continue to decrease. Because the second temperature sensor 120 is located in an independent heat-insulating space 310 and is more in contact with the external environment, the temperature response of the second temperature sensor 120 is faster than the temperature response of the first temperature sensor 110; the decrease rate of the second temperature T2 is greater than the decrease rate of the first temperature T1; when the first temperature T1 drops to be equal to the second temperature T2, that is, T2=T1; it indicates that the overall heat dissipation of the code table is completed or it has not been exposed to the sun, that is, h=0.

[0048] The state S3 can be recorded as a state where the temperature of the code computer 300 does not rise.

[0049] In some embodiments of the present invention, continue to refer to Figure 4 As shown, first, the temperature is not raised in the state S3, riding preparation, and the code meter is turned on 300.

[0050] After that, the riding starts, the ultraviolet light sensor 130 detects the sun exposure signal, and the computer 300 enters the sun exposure heating stage in the sun exposure state S1. At this time, h>0, and the first temperature T1 and the second temperature T2 continue to rise; then the actual temperature difference ∆T satisfies the following formula 1: ; Wherein, ∆T is the actual temperature difference; a and b are heating time constants; h is the duration of sunlight exposure; d is the speed constant; V is the running speed. In this stage, when the GNSS chip 140 collects the current running speed as V1, V=V1; when the GNSS chip 140 collects the current running speed as V2, V=V2; T1 is the first temperature; T2 is the second temperature; is the actual temperature difference when the code meter 300 switches from the sun exposure state to the non-sun exposure state; It is the actual temperature difference when the code meter 300 switches from the non-sunlight state to the sunlight state.

[0051] In the stage, because the code table 300 enters the sun exposure state for the first time after being started, that is, it has not been switched between the sun exposure state and the non-sun exposure state, and Both are 0.

[0052] In some embodiments of the present invention, continue to refer to Figure 4 As shown, when the cycling computer 300 is in a non-sun exposure state and the sun exposure time is greater than 0, that is, the cycling is performed in a cool area without direct sunlight, the first temperature T1 and the second temperature T2 are slightly reduced, that is, the current state is the non-sun exposure cooling stage of the sun exposure state S1; the actual temperature difference Satisfies the following formula 2: ; Among them, ∆T is the actual temperature difference; g is the heat dissipation time constant; h is the sunshine time; h0 is the non-sunlight time; d is the speed constant; V3 is the running speed; T1 is the first temperature; T2 is the second temperature; k is the heat dissipation coefficient.

[0053] Among them, the calculation formula of heat dissipation coefficient k is: ; in, is the actual temperature difference when the code meter 300 switches from the sun exposure state to the non-sun exposure state, calculated by formula 1: ; V2 is the running speed of the computer 300 when it switches from the sun exposure state to the non-sun exposure state; Save it for subsequent actual temperature difference calculation.

[0054] In some embodiments of the present invention, continue to refer to Figure 4 As shown, the code meter 300 enters the sunlight again, and the code meter 300 enters the sunlight state from the non-sunlight state, that is, returns to the sunlight temperature rise stage of the sunlight state S1, and the ultraviolet light sensor 130 re-records the sunlight duration h, and the sunlight duration h of the previous stage is reset; Formula 1 is still used to calculate ∆T: ; Wherein, V is the running speed. In this stage, when the GNSS chip 140 collects the current running speed as V4, V=V4; when the GNSS chip 140 collects the current running speed as V5, V=V5; is the actual temperature difference when the code meter 300 switches from the non-sunlight state to the sunlight state, calculated using Formula 2: .

[0055] V3 is the running speed of the computer 300 when it switches from the non-sunlight state to the sunlight state; Save it for subsequent actual temperature difference calculation.

[0056] In some embodiments of the present invention, continue to refer to Figure 4 As shown, when the second temperature T2 continues to rise to be equal to the first temperature T1, the code table 300 enters the sun-drying stage; in the sun-drying stage, the actual temperature difference is a constant value; substituting T1= T2 into formula 1, the calculation formula for the actual temperature difference in the sun-drying stage is obtained as follows:

[0057] Where ∆T is the actual temperature difference; d is the speed constant; V6 is the running speed of the code meter 300 in the current sun exposure stage; is the actual temperature difference when the code meter 300 switches from the sun exposure state to the non-sun exposure state, ; is the actual temperature difference when the code meter 300 switches from the non-sunlight state to the sunlight state, .

[0058] In some embodiments of the present invention, continue to refer to Figure 4 As shown, the code computer 300 enters the non-sun exposure state and is in the shade for a long time, and the first temperature T1 and the second temperature T2 continue to decrease, that is, it is currently in the non-sun exposure cooling stage of the sun exposure state S1; the ultraviolet light sensor 113 re-records the non-sun exposure time h0, and the non-sun exposure time h0 of the previous stage is reset; The actual temperature difference when the code meter 300 switches from the previous sun exposure state to the current non-sun exposure state, and its value is updated: ; The actual temperature difference is still calculated using Formula 2: ; Among them, ∆T is the actual temperature difference; g is the heat dissipation time constant; h is the sun exposure time; h0 is the non-sun exposure time; d is the speed constant; V7 is the operating speed; T1 is the first temperature; T2 is the second temperature; k is the heat dissipation coefficient.

[0059] Among them, the calculation formula of heat dissipation coefficient k involves Updated to: .

[0060] In some embodiments of the present invention, continue to refer to Figure 4 As shown, when the first temperature T1 and the second temperature T2 continue to drop for a long time, the drop rate of the second temperature T2 is greater than the drop rate of the first temperature T1. Therefore, when the first temperature T1 is equal to the second temperature T2 again, the temperature collected by the first temperature sensor 110 and the second temperature sensor 120 is the actual temperature; the code table 300 has no additional temperature rise and reaches the non-temperature rise state S3. In this state, the sun exposure time h, the non-sun exposure time h0, and All cleared.

[0061] The actual temperature difference ∆T calculated by the above formula is used to calculate the current ambient temperature, i.e. the actual temperature T: T=T2-∆T.
