[0041] Satellite communications play an important role in aviation, transportation, ocean polar regions, vehicle monitoring and other scenarios. Common satellite communication equipment includes IoT terminals, handheld terminals, vehicle-mounted data terminals, navigation enhancement terminals, etc. Each satellite communication device includes a communication module. The power consumption of the communication module is directly related to the transmission power. The greater the transmission power of the communication module, the greater the power consumption. In the prior art, a larger transmission power is usually used to ensure communication quality, but the actual transmission power may far exceed the requirements of the satellite communication equipment, resulting in high power consumption of the communication module.

[0042] In view of this, a technical solution of an embodiment of the present application is provided to reduce the power consumption of the communication module while ensuring the communication quality.

[0043] In view of the above scenario, the transmission power adjustment method provided by the present invention is described in detail below in conjunction with the accompanying drawings of the specification. It should be noted that the method is applied to satellite communication services.

[0044] See also Figure 1, is a flowchart of a method for adjusting transmit power according to an embodiment of the present application. The method can be executed by a computer device, such as a laptop computer, a desktop computer, and a server, and can also be applied to various devices with computing capabilities. The above devices are only examples, and the embodiments of the present application are not limited thereto.

[0045] Taking the method executed by the server as an example below, the method includes:

[0046] S101: Determine a plurality of first particles corresponding to the same communication module set.

[0047] The communication module set includes multiple communication modules, and one communication module belongs to one satellite communication device. Each first particle includes multiple transmission powers, and one item in each first particle is used to represent the transmission power of one communication module in the communication module set.

[0048] In one implementation, the correspondence between the communication module set and the multiple first particles is shown in Table 1 below. In Table 1, the communication module set includes communication module A to communication module D, the multiple first particles are composed of first particles 1 to first particles 3, and a1 to d3 are all transmission powers. The transmission powers in the same row belong to the same first particle, for example, first particle 1 = (a1, b1, c1, d1), and the transmission powers in the same column belong to the same communication module, for example, the transmission powers a1 to a3 are all used to represent the transmission power of communication module A.

[0049] Table 1

[0050] Communication module A Communication module B Communication module C Communication module D First Particle 1 a1 b1 c1 d1 First Particle 2 a2 b2 c2 d2 First Particle 3 a3 b3 c3 d3

[0051] In one implementation, the communication modules can be divided into Internet of Things modules, mobile communication modules, and broadband communication modules according to their types. The types of multiple communication modules in a communication module set can be the same or different, and the embodiments of the present application do not limit this.

[0052] In order to ensure that each transmission power included in each first particle meets the communication condition, the directly acquired second particles need to be processed as follows.

[0053] In one implementation, multiple second particles corresponding to the communication module set are obtained, and it is determined whether each transmission power included in each second particle is greater than or equal to a first threshold. For any communication module, a transmission power greater than or equal to the first threshold satisfies the communication condition.

[0054] If there is a second particle whose transmission powers are all greater than or equal to the first threshold, the second particle is used as the first particle, and / or, for the second particle that does not meet the above conditions, the transmission power of the particle that is less than the first threshold is adjusted to obtain an adjusted second particle, and the adjusted second particle is used as the first particle, the adjusted transmission power is greater than or equal to the transmission power before the adjustment, and the adjusted transmission power meets the communication condition.

[0055] Among them, the communication conditions may include, for a transmission power, sending a test message to the communication module and receiving a test response message, obtaining the round-trip delay of the communication module at the transmission power, and the round-trip delay is within a preset range.

[0056] It can be understood that the value of the first threshold can be determined according to actual needs, and the communication conditions can also include other conditions, which are not limited in the embodiments of the present application.

[0057] Exemplarily, the second particle 1 = (20, 23, 17, 19, 22) (unit: dm) and the first threshold is 15. Since each emission power included in the second particle 1 is greater than 15, the second particle 1 is taken as the first particle.

[0058] In the embodiments of the present application, there are many ways to obtain second particles. The most common method is to use a spectrometer to collect the transmission power of multiple communication modules within a certain range, obtain the transmission power of multiple communication modules collected by the spectrometer, and use the transmission power collected by the spectrometer at the same time as a second particle.

[0059] It is understandable that the plurality of second particles corresponding to the communication module set may also be obtained by other methods, which are not limited in the embodiment of the present application.

[0060] Through this method, since the transmission powers included in the second particle may not all meet the communication conditions, the transmission powers that may not meet the communication conditions can be preliminarily screened out through the first threshold judgment, and then these transmission powers are adjusted. The adjusted transmission powers must meet the communication conditions, and the minimum transmission power obtained subsequently also meets the communication conditions, thereby ensuring the reliability of the solution.

[0061] The following describes a method for adjusting the transmit power that is less than the first threshold.

[0062] In one implementation, for any transmission power less than the first threshold, a test message is sent to the communication module corresponding to the transmission power and a test response message is received to obtain the round-trip delay of the communication module corresponding to the transmission power at the transmission power. If the round-trip delay is within a preset range, the transmission power is maintained unchanged, in other words, the transmission power before adjustment is equal to the transmission power after adjustment; if the round-trip delay is outside the preset range, the transmission power is adjusted to a value not less than the first threshold.

[0063] Through this method, for a transmission power less than a threshold, whether the communication module can communicate normally can be determined by the round-trip delay of the communication module at the transmission power, thereby ensuring that each transmission power included in any first particle among the multiple first particles can meet the communication conditions, thereby ensuring the reliability of the solution.

[0064] In another implementation, the transmission power belonging to the same communication module in multiple second particles is determined to obtain a transmission power set corresponding to each communication module; for any transmission power less than a first threshold in any transmission power set, a test message is sent to the communication module corresponding to any transmission power set and a test response message is received to obtain a round-trip delay of the communication module corresponding to any transmission power set at any transmission power less than the first threshold.

[0065] If the round-trip delay is within the preset range, the transmit power is maintained unchanged. In other words, the transmit power before adjustment is equal to the transmit power after adjustment, and the value of the transmit power is used as the second threshold. Since the round-trip delay of the communication module corresponding to the transmit power set to which the transmit power belongs is within the preset range and meets the communication conditions, the transmit powers greater than or equal to the second threshold in the transmit power set can meet the communication conditions. There is no need to further judge through the round-trip delay. It is only necessary to adjust the transmit power less than the second threshold in the transmit power set. The adjusted transmit power is greater than or equal to the transmit power before adjustment, and the adjusted transmit power meets the communication conditions.

[0066] If the round trip delay is outside the preset range, the transmit power is adjusted to a value not less than the first threshold, and the remaining transmit powers in the transmit power set to which the transmit power belongs are continuously judged by the first threshold.

[0067] Exemplarily, see Table 2 below, the first threshold is 20, and the unit of each transmission power is dm. In Table 2, the transmission power set corresponding to communication module E is (20, 10, 22, 20), the transmission power set corresponding to communication module F is (30, 25, 17, 20), and the transmission power set corresponding to communication module G is (20, 18, 19, 15). Taking communication module G as an example, the transmission power less than the first threshold is 18dm, 19dm, and 15dm. A test message is sent to communication module G and a test response message returned by communication module G with a transmission power of 18dm is received. The round-trip delay of communication module G when the transmission power is 18dm is obtained. The round-trip delay is within the preset range, that is, communication module G can communicate normally when the transmission power is 18dm, and 18 is used as the second threshold. At this time, since 19 is greater than 18, 19dm is kept unchanged. Next, the transmission power that is less than the second threshold in the transmission power set corresponding to the communication module G is 15dm. A test message is sent to the communication module G and a test response message returned by the communication module G with a transmission power of 15dm is received. The round-trip delay of the communication module G when the transmission power is 15dm is obtained. The round-trip delay is not within the preset range. The transmission power is adjusted to 18dm (or above 18dm), and finally the transmission power set corresponding to the communication module G is (20, 18, 19, 18).

[0068] Table 2

[0069] Communication module E Communication module F Communication module G Second Particle 2 20 30 20 Second Particle 3 10 25 18 Second Particle 4 22 17 19 Second Particle 5 20 20 15

[0070] It can be understood that the processing method of the transmission power set corresponding to the remaining communication modules is the same as the processing method of the transmission power set corresponding to the communication module G, which will not be repeated here.

[0071] Through this method, if the round-trip delay of the communication module corresponding to any transmission power set meets the communication conditions at any transmission power less than the first threshold, the value of the transmission power can be used as the second threshold. Thereafter, there is no need to adjust all the transmission powers less than the first threshold in the transmission power set. Only the transmission powers less than the second threshold in the transmission power set need to be adjusted. Since the second threshold is less than the first threshold, the number of adjustments is reduced, thereby improving the adjustment efficiency of the transmission power.

[0072] Optionally, after obtaining the round-trip delay of the communication module corresponding to any transmission power set at any transmission power less than the first threshold, the transmission power judgment range can also be determined according to the relationship between the round-trip delay and the preset range. The transmission power greater than or equal to the maximum value of the transmission power judgment range must meet the communication conditions, and the transmission power less than or equal to the minimum value of the transmission power judgment range must not meet the communication conditions. If the round-trip delay is within the preset range, the transmission power is maintained unchanged, and the value of the transmission power is used as the maximum value of the transmission power judgment range; if the round-trip delay is outside the preset range, the value of the transmission power is adjusted to a value not less than the first threshold, and the value of the transmission power is used as the minimum value of the transmission power judgment range.

[0073] For other transmission powers in any transmission power set, judgments are made in turn: if there is a transmission power that is less than the minimum value of the transmission power judgment range, the transmission power is adjusted to a value not less than the maximum value of the current transmission power judgment range; if there is a transmission power that is greater than the maximum value of the transmission power judgment range, the transmission power is maintained unchanged; if there is a transmission power that belongs to the transmission power judgment range, the round-trip delay of the communication module corresponding to the set to which the transmission power belongs is obtained at the transmission power, and the transmission power judgment range is updated and the transmission power itself is adjusted according to the relationship between the round-trip delay and the preset range in the previous step.

[0074] Similarly, taking the communication module G in Table 2 as an example, after determining that the communication module G can communicate normally when the transmission power is 18dm, and the communication module G cannot communicate normally when the transmission power is 15dm, [15dm, 18dm] is used as the transmission power judgment range of the communication module G. For other transmission powers in the communication module G (not shown in Table 2), if there is a transmission power greater than 18dm, since the transmission power greater than 18dm must meet the communication conditions, the transmission power remains unchanged; if there is a transmission power less than 15dm, since the transmission power less than 15dm must not meet the communication conditions, then The value of the transmit power is adjusted to 18dm (or above 18dm); if there is a transmit power between 15dm and 18dm, such as 17dm, it is necessary to determine whether the transmit power meets the communication conditions through the round-trip delay. If the round-trip delay is within the preset range, the transmit power judgment range is adjusted to [15dm, 17dm], and the above steps are repeated for other transmit powers. If the round-trip delay is outside the preset range, the transmit power is adjusted to 18dm, and the transmit power judgment range is adjusted to [17dm, 18dm]. The above steps are repeated for each of the other transmit powers.

[0075] Through this method, since the transmission power less than the minimum value of the transmission power judgment range must not meet the communication conditions, it can be directly adjusted to a value not less than the maximum value of the transmission power judgment range. The transmission power greater than the maximum value of the transmission power judgment range can be maintained unchanged. In this way, it is only necessary to test the round-trip delay of the transmission power within the transmission power judgment range, which reduces the number of test messages sent and further improves the adjustment efficiency of the transmission power.

[0076] S102: Processing multiple first particles based on the particle swarm algorithm to obtain a global optimal particle.

[0077] The particle swarm algorithm is a method that starts from a group of random solutions and obtains the optimal solution through iteration. In each iteration, the particle is updated according to the optimal solution of the particle itself and the optimal solution in the population.

[0078] The global optimal particle represents the minimum transmission power of each communication module in the communication module set when the communication conditions are met.

[0079] In one implementation, see Figure 2 The following takes the first particle group iteration of multiple first particles as an example to introduce the specific steps included in the above step S102:

[0080] S201: summing up the emission powers of each first particle to obtain the fitness of each first particle.

[0081] The fitness of each first particle can be expressed by the following formula (1).

[0082]

[0083] Among them, g k (j) represents the fitness of the jth first particle in the kth iteration process, m represents the total number of m communication modules in the communication module set, i represents the i-th communication module, It represents the transmission power of the jth particle corresponding to the i-th communication module at the k-th iteration.

[0084] Using the example of Table 1 in S101 above, the fitness of the first particle 1 g 1 (1) = a1+b1+c1+d1, the fitness of the first particle 2 is g 1 (2) = a2+b2+c2+d2, the fitness of the first particle 3 is g 1 (3) = a3+b3+c3+d3.

[0085] S202: taking the first particle with the smallest fitness among the multiple first particles as the local optimal particle.

[0086] Using the example of Table 1 in S101 above, the fitness g of the first particle 1 is 1 (1) The fitness g of the first particle 2 1 (2) The fitness g of the first particle 3 1 (3) Compare the sizes and take the first particle with the smallest fitness as the local optimal particle.

[0087] S203: Determine whether the local optimal particle meets the iteration termination condition. If so, execute step S204; if not, execute step S205.

[0088] The iteration termination condition includes that the difference between the fitness of the current local optimal particle and the fitness of the local optimal particle in the previous particle swarm iteration is less than a third threshold, or the number of particle swarm iterations corresponding to the current local optimal particle reaches a preset number.

[0089] It is understandable that the third threshold and the preset number of times can be specified according to actual needs, and the embodiment of the present application does not limit this.

[0090] S204: Determine the local optimal particle as the global optimal particle.

[0091] Continuing with the example of Table 1 in S101 above, assuming that the global optimal particle is the first particle 1 = (a1, b1, c1, d1), the minimum transmission power of communication module A is a1, the minimum transmission power of communication module B is b1, the minimum transmission power of communication module C is c1, and the minimum transmission power of communication module D is d1.

[0092] S205: performing particle swarm iteration on the plurality of first particles to obtain a plurality of iterated first particles, and determining a global optimal particle according to the plurality of iterated first particles.

[0093] The particle swarm iteration is to shift each first particle towards the local optimal particle.

[0094] Particle swarm iteration can be expressed by the following formulas (2) to (5).

[0104] The particle swarm is iterated on the multiple first particles by using the above formulas (2) to (5) to obtain the multiple first particles after iteration, and then the process jumps to step S201. Steps S201 to S205 are repeated according to the multiple first particles after iteration, and so on, until the global optimal particle is obtained.

[0105] In one implementation, the latest multiple first particles are periodically determined at preset time intervals, and steps S201 to S205 are performed based on the latest multiple first particles to determine the global optimal particle.

This scheme can calculate the minimum transmission power of multiple communication modules at one time, and has high calculation efficiency; the global optimal particle obtained by the particle swarm algorithm is more accurate, and each of the particles input to the particle swarm algorithm meets the communication conditions, so that the global optimal particle can more accurately characterize the minimum transmission power of each communication module when the communication conditions are met, effectively reducing the power consumption of each communication module.
