[0035] Embodiment one

[0036] Figure 1 A flowchart of a transmit power adjustment method provided by the first embodiment of the present application is shown in the figure. The method can be applied to the case of transmitting a short message by a Beidou communication terminal, and the method can be executed by a transmit power adjustment device. The device can be realized by software and / or hardware, and is generally integrated on an electronic device.

[0037] As shown in Figure 1 The transmit power adjustment method provided by the first embodiment of the present application includes the following steps:

[0038] S110, determining the basic transmit power of the Beidou communication terminal.

[0039] The basic transmit power can be understood as the initial transmit power of the Beidou communication terminal.

[0040] In the embodiment, a transmitting power can be set according to a priori value for self-transmitting and self-receiving of the Beidou signal, and a communication success rate is counted, if the communication success rate is greater than or equal to a preset value, the value of the transmitting power can be gradually reduced until the communication success rate corresponding to the transmitting power is less than the preset value, at this time, the previous transmitting power value corresponding to the transmitting power with the communication success rate less than the preset value can be taken as the basic transmitting power of the Beidou communication terminal, if the communication success rate is less than the preset value, the value of the transmitting power can be gradually increased until the communication success rate corresponding to the transmitting power is greater than or equal to the preset value, at this time, the transmitting power can be taken as the basic transmitting power of the Beidou communication terminal.

[0041] The communication success can mean that the Beidou communication terminal can successfully receive the feedback signal after transmitting the Beidou signal with the transmitting power.

[0042] S120, a lookup table is established based on the basic transmitting power, and the lookup table at least includes the basic transmitting power and channel attenuation values corresponding to different times.

[0043] The channel attenuation value can be understood as a wireless channel attenuation parameter, and a signal attenuation term caused by channel attenuation needs to be considered when calculating the signal receiving power, and different signal receiving powers reflect different channel attenuation values.

[0044] It should be noted that under the condition of vacuum, the Beidou signal power received by the ground is calculated by the following formula:

[0045] Pr dB =Pt dB +Gt dB +Gr dB +20log 10 C-20log 10 (4πdf)

[0046] Wherein, Pr represents the receiving power, unit dB; Pt represents the satellite transmitting power, unit dB; Gt represents the gain of the satellite transmitting antenna, Gr represents the antenna gain of the ground receiving terminal; C represents the transmission rate of the optical electromagnetic wave in the air, unit 3×10 8 m / s; d represents the distance between the satellite and the ground terminal, unit m; f represents the frequency of the Beidou signal, unit Hz.

[0047] The above formula does not consider the channel attenuation value, and the influence of weather environment at different times on the transmitting power needs to be considered in the actual scene, the channel attenuation value is used to represent the influence of weather environment at different times on the transmitting power in the application, and the receiving power is calculated by adding the channel attenuation value on the basis of the above formula, therefore, the channel attenuation value corresponding to the transmitting power needs to be included in the lookup table.

[0048] In this embodiment, after the Beidou communication terminal performs multiple self-transmission and self-reception at the time t0 with the basic transmission power, the values of multiple received powers can be counted, and then the average value of the received power at the time t0 can be calculated; after the Beidou communication terminal performs multiple self-transmission and self-reception at the time t1 with the basic transmission power, the values of multiple received powers can be counted, and then the average value of the received power at the time t1 can be calculated; the channel attenuation value corresponding to the basic transmission power can be calculated according to the average value of the received power at the time t0 and the average value of the received power at the time t1.

[0049] S130, determining a new basic transmission power according to the basic transmission power and the channel attenuation value.

[0050] In this embodiment, the basic transmission power is not applicable to the weather environment at the next time, and therefore the basic transmission power needs to be updated according to the channel attenuation value at the next time.

[0051] In this embodiment, the basic transmission power of the signal and the channel attenuation value at the next time can be obtained from the lookup table, the basic transmission power minus the channel attenuation value at the next time can obtain the transmission power at the next time, and the transmission power can be used as the new basic transmission power.

[0052] S140, determining whether to update the basic transmission power included in the lookup table according to the new basic transmission power.

[0053] In this embodiment, after the Beidou communication terminal performs multiple self-transmission and self-reception with the new basic transmission power, the communication success rate of multiple self-transmission and self-reception can be counted, if the communication success rate is greater than or equal to a preset value, it is determined that the basic transmission power needs to be updated; if the communication success rate is less than or equal to the preset value, it is determined that the basic transmission power does not need to be updated.

[0054] S150, if yes, the new basic transmission power is used as the basic transmission power of the terminal device.

[0055] In this embodiment, if it is determined that the basic transmission power needs to be updated, the new basic transmission power can replace the original basic transmission power; if it is determined that the basic transmission power does not need to be updated, it means that the basic transmission power is still applicable to the weather environment at the current time, and the basic transmission power does not need to be changed.

[0056] The embodiment one of the present application provides a transmitting power adjustment method, which comprises the following steps: firstly, determining a basic transmitting power of a Beidou communication terminal; secondly, establishing a lookup table based on the basic transmitting power, wherein the lookup table comprises at least the basic transmitting power and channel attenuation values corresponding to different times; thirdly, determining a new basic transmitting power according to the basic transmitting power and the channel attenuation values; fourthly, determining whether the basic transmitting power included in the lookup table is updated according to the new basic transmitting power; and finally, if yes, taking the new basic transmitting power as the basic transmitting power of the terminal equipment. The method can avoid wasting power consumption by establishing the lookup table and updating the basic transmitting power in the lookup table to adapt to the transmitting power required in different weather environments.

[0057] Embodiment two

[0058] Figure 2 The embodiment two of the present application provides a transmitting power adjustment method, which is based on the optimization of the above-mentioned embodiments. In the embodiment, the basic transmitting power of the Beidou communication terminal is further specified. The details of the embodiment can be referred to the embodiment one.

[0059] As shown in the figure, the transmitting power adjustment method provided by the embodiment two of the present application comprises the following steps: Figure 2

[0060] S210, determining a first transmitting power according to a priori value.

[0061] The priori value can be an empirical value of the transmitting power obtained after multiple signal transmissions.

[0062] In the embodiment, taking the priori value as the first transmitting power can greatly improve the communication success rate.

[0063] S220, determining a first communication success rate of the Beidou communication terminal performing multiple self-transmission and self-reception at the first transmitting power.

[0064] It should be noted that the first transmitting power and the second transmitting power are only named to distinguish the different transmitting powers, and have no actual meaning, and the first communication success rate and the second communication success rate are also named to distinguish the different communication success rates, and have no actual meaning.

[0065] The first communication success rate can be obtained by determining the communication success rate of the multiple self-transmission and self-reception after the Beidou communication terminal performs the multiple self-transmission and self-reception at the first transmitting power.

[0066] S230, if the first communication success rate is greater than or equal to a preset value, reducing the first transmitting power to obtain a second transmitting power.

[0067] ​The preset value can be set by itself, and is not specifically limited here. For example, the preset value can be 95%.

[0068] The first transmission power can be reduced by a preset step. For example, the first transmission power can be reduced by a step of 0.5 dB.

[0069] S240, a second communication success rate of the Beidou communication terminal performing multiple transmissions at the second transmission power is counted.

[0070] The second communication success rate can be obtained by counting the communication success rates of the multiple self-transmissions and self-receptions.

[0071] S250, if the second communication success rate is greater than or equal to a preset value, the second transmission power continues to be reduced until the second communication success rate is less than the preset value, and the second transmission power calculated in the second last time is taken as the basic transmission power of the Beidou communication terminal.

[0072] The preset value is the preset value in step S230.

[0073] For example, the first transmission power is 30 dB, the second transmission power obtained by reducing the first transmission power by a step of 0.5 dB in the first time is 39.5 dB, the second transmission power obtained by continuing to reduce the second transmission power by a step of 0.5 dB in the second time is 39 dB, and if the communication success rate corresponding to the transmission power of 39 dB is less than the preset value, the second transmission power of 39.5 dB can be taken as the basic transmission power of the Beidou communication terminal.

[0074] Further, if the first communication success rate is less than the preset value, a third transmission power is obtained by increasing the first transmission power, a third communication success rate of the Beidou communication terminal performing multiple self-transmissions and self-receptions at the third transmission power is counted, and if the third communication success rate is less than the preset value, the third transmission power continues to be increased until the third communication success rate is greater than or equal to the preset value, and the third transmission power is taken as the basic transmission power of the Beidou communication terminal.

[0075] The preset value is the preset value in steps S230 and S250. The third transmission power is a different name for distinguishing the first transmission power and the second transmission power, and has no actual meaning. The third communication success rate is a different name for distinguishing the first communication success rate and the second communication success rate, and has no actual meaning.

[0076] For example, if the first transmission power is 30 dB, the first transmission power is increased by 0.5 dB to obtain a third transmission power of 30.5 dB, and after the Beidou communication terminal performs multiple self-transmission and self-reception at the transmission power of 30.5 dB, the communication success rate of the multiple self-transmission and self-reception is obtained to obtain a third communication success rate; it is determined whether the third communication success rate is greater than or equal to 95%, if not, the third transmission power of 30.5 dB is further increased by 0.5 dB to obtain a third transmission power of 31 dB, if the third communication success rate corresponding to the third transmission power of 31 dB is greater than or equal to 95%, the third transmission power of 31 dB can be used as the basic transmission power of the Beidou communication terminal.

[0077] S260, establishing a lookup table based on the basic transmission power, the lookup table at least including the basic transmission power and channel attenuation values corresponding to different times.

[0078] S270, determining a new basic transmission power according to the basic transmission power and the channel attenuation values.

[0079] S280, determining whether to update the basic transmission power included in the lookup table according to the new basic transmission power.

[0080] S290, if yes, the new basic transmission power is used as the basic transmission power of the terminal device.

[0081] The embodiment two of the application provides a transmission power adjustment method, which specifically determines the basic transmission power, and the basic transmission power determined by the method is more accurate and effective.

[0082] Further, the Beidou communication terminal performs self-transmission and self-reception at different transmission powers for more than or equal to 20 times;

[0083] The second transmission power is greater than or equal to a preset minimum transmission power;

[0084] The third transmission power is less than the maximum transmission power of the Beidou communication terminal.

[0085] The preset minimum transmission power can be 3 dB, and 3 dB is a priori value.

[0086] Embodiment three

[0087] Figure 3 A flowchart of a transmission power adjustment method provided by the embodiment three of the application is provided, and the embodiment three is optimized on the basis of the above-mentioned embodiments. In the embodiment, the establishment of the lookup table based on the basic transmission power is further specified. The details of the embodiment are described in the embodiment one.

[0088] AsFigure 3 As shown, the method for adjusting transmitting power provided by the third embodiment of the present application comprises the following steps:

[0089] S310, determining a basic transmitting power of the Beidou communication terminal.

[0090] S320, calculating an average of a plurality of receiving powers obtained after the Beidou communication terminal performs a plurality of self-transmitting and self-receiving operations at a first time with the basic transmitting power, and taking the average of the plurality of receiving powers as a first average receiving power.

[0091] The first average receiving power and the second average receiving power are only different names for distinguishing the average receiving powers, and have no actual meaning.

[0092] For example, the Beidou communication terminal can calculate an average of a plurality of receiving powers obtained after performing a plurality of self-transmitting and self-receiving operations at t0 with the basic transmitting power, and obtain the first average receiving power.

[0093] S330, calculating an average of a plurality of receiving powers obtained after the Beidou communication terminal performs a plurality of self-transmitting and self-receiving operations at a second time with the basic transmitting power, and taking the average of the plurality of receiving powers as a second average receiving power.

[0094] The second time is later than the first time, and a time interval between the second time and the first time is a preset value.

[0095] For example, if the first time is 10:00 am, the second time can be 5:00 pm.

[0096] For example, the Beidou communication terminal can calculate an average of a plurality of receiving powers obtained after performing a plurality of self-transmitting and self-receiving operations at t1 with the basic transmitting power, and obtain the second average receiving power.

[0097] S340, calculating a difference between the first average receiving power and the second average receiving power, and obtaining a channel attenuation value corresponding to the second time.

[0098] The difference between the first average receiving power and the second average receiving power can be taken as the channel attenuation value corresponding to the second time.

[0099] S350, storing the basic transmitting power and the channel attenuation value in a lookup table.

[0100] Optionally, the lookup table can further include the first average receiving power and the second average receiving power.

[0101] S360, determining a new basic transmitting power according to the basic transmitting power and the channel attenuation value.

[0102] Specifically, the base transmission power is reduced by the channel attenuation value corresponding to the second time to obtain a new base transmission power.

[0103] S370, determining whether to update the base transmission power included in the lookup table according to the new base transmission power.

[0104] Specifically, the communication success rate of the Beidou communication terminal transmitting multiple times with the new base transmission power is counted; if the communication success rate is greater than or equal to a preset value, it is determined that the base transmission power included in the lookup table is updated; if the communication success rate is less than the preset value, it is determined that the base transmission power included in the lookup table does not need to be updated.

[0105] The preset value can be set according to actual conditions, which is not limited here, and the preset value can be 95% for example.

[0106] S380, if yes, the new base transmission power is taken as the base transmission power of the terminal device.

[0107] The transmission power adjustment method provided by the third embodiment of the application specifically implements the establishment process of the lookup table. The lookup table established by the method includes channel attenuation values corresponding to different times, and the transmission power is adjusted according to the channel attenuation values to adapt to the transmission power demand in different weather environments.

[0108] The embodiments of the application provide several specific implementation manners on the basis of the technical solutions of the above-mentioned embodiments.

[0109] As a specific implementation manner of the embodiment, Figure 4 A flowchart of a transmission power adjustment method provided by a specific embodiment of the application is shown in the figure, Figure 4The process is as follows: Based on the prior value P0 (the first transmission power), perform self-transmission and self-reception of BeiDou signals, with at least 20 transmissions. Calculate the communication success rate and determine if it is greater than 95%. If so, decrease the transmission power P0 in 0.5dB steps, but P0 cannot fall below the prior value by 3dB. Continue self-transmission and self-reception for at least 20 times, and calculate the communication success rate again. If the communication success rate is greater than 95%, continue decreasing the transmission power P0 in 0.5dB steps until the corresponding communication success rate is less than 95%. Determine the base transmission power P1, which is the transmission power with a communication success rate less than 95%, and store P1 in a lookup table. If the communication success rate corresponding to P0 is less than 95%, increase the transmission power P0 in 0.5dB steps, but P0 cannot exceed the device's maximum transmission power. Continue self-transmission and self-reception for at least 20 times, and calculate the communication success rate again. If the communication success rate is still less than 95%,... If the success rate is 95%, the transmit power P0 is increased in 0.5 dB increments until the communication success rate is greater than or equal to 95%. The transmit power with a communication success rate greater than or equal to 95% is taken as the base transmit power P1 and stored in a lookup table. The average value PR0 of the multiple receive powers corresponding to the base transmit power P1 is calculated, which is the first average receive power, and PR0 is stored in a lookup table. After a specified time interval, multiple self-transmission and self-reception operations are performed using the base transmit power P1. The average value PR1 of the multiple receive powers is calculated, which is the second average receive power, and PR1 is stored in a lookup table. The wireless channel attenuation difference value ΔPr = PR0 - PR1 is calculated. The base transmit power P1 is obtained from the lookup table, and a new base transmit power P2 = P1 - ΔPr is obtained. Based on P2, BeiDou signals are self-transmitted and self-received at least 20 times, and the communication success rate is calculated. If the communication success rate is greater than or equal to 95%, P1 in the lookup table is updated to P2.
