Description

Technical Field

[0001] This application relates to the field of power consumption measurement technology, and in particular to power consumption measurement methods, systems, transmitting devices, processing devices, and storage media. Background Technology

[0002] Satellite positioning equipment has been widely used in many fields such as vehicle navigation, Internet of Things terminals, and wearable positioning devices. Its power consumption performance directly determines the device's battery life, power supply design, and overall reliability, and is a core technical indicator in the research and development and performance optimization of satellite positioning terminals.

[0003] In the power consumption testing and evaluation of satellite positioning equipment, it is necessary to accurately collect and analyze the power consumption distribution of different functional modules and under different working conditions within the equipment, so as to provide data support for module power consumption control, power management strategy optimization, and low-power algorithm design.

[0004] Most existing power consumption measurement schemes for satellite positioning equipment adopt a single-channel acquisition and measurement architecture, which can only realize single-point detection of the overall power consumption of the equipment, and cannot simultaneously complete the parallel power consumption measurement of multiple independent power supply channels or multiple functional modules. Summary of the Invention

[0005] This application provides a power consumption measurement method, system, transmitting device, processing device, and storage medium, which can perform multi-channel power consumption measurement when measuring the power consumption of various power-consuming devices in a satellite positioning device.

[0006] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, a power consumption measurement method is provided. This method is applied to a transmitting device in a satellite positioning device, which further includes a processing device, a data bus, multiple power-consuming devices, and multiple power consumption measurement devices. Each power consumption measurement device measures the power consumption of one power-consuming device. Each power consumption measurement device is connected to the data bus, which is also connected to the transmitting device. The transmitting device is also connected to the processing device. The method includes: the transmitting device receiving measurement data packets collected by each of the multiple power consumption measurement devices; the measurement data including the device number of the power consumption measurement device, the power consumption measurement value, and the power consumption measurement time; the transmitting device determining whether the number of measurement data packets received at the same time is multiple; if the number of measurement data packets received at the same time is multiple, the transmitting device determining the transmission order of the multiple measurement data packets received at the same time based on the device number in the multiple measurement data packets received at the same time; and the transmitting device transmitting the multiple measurement data packets received at the same time to the processing device based on the transmission order.

[0007] Based on this scheme, a one-to-one independent measurement architecture is constructed by configuring a corresponding power consumption measurement device for each power-consuming device in the satellite positioning system. This hardware-level approach ensures that the power consumption of multiple power-consuming devices can be collected simultaneously and independently. Each power consumption measurement device uploads a data packet carrying the device number, power consumption measurement value, and measurement time in parallel via a data bus, providing basic hardware and transmission support for multi-channel power consumption measurement. The transmitting device identifies the scenario of concurrent data transmission by judging the number of measurement data packets received at the same time and determines the orderly transmission order based on the device number in the data packet. This effectively avoids conflicts and errors caused by simultaneous transmission of multiple data packets, ensuring that all measurement data can be transmitted completely and orderly to the subsequent processing device.

[0008] In conjunction with the first aspect, in some embodiments of the first aspect, when the number of measurement data packets received at the same time is multiple, the transmitting device determines the transmission order of the multiple measurement data packets received at the same receiving time based on the device number in the multiple measurement data packets received at the same receiving time, including: sorting the device numbers in the multiple measurement data packets received at the same receiving time to obtain a sorting result of the multiple device numbers; and using the sorting result of the multiple device numbers as the transmission order of the multiple measurement data packets received at the same receiving time.

[0009] By sorting the device numbers in multiple measurement data packets received at the same time and using the sorting result as the sending order of the corresponding measurement data packets, the normalization and orderly scheduling of the data packet sending order can be achieved when multiple power measurement data are transmitted concurrently. This avoids data conflicts, packet loss, and timing disorder caused by simultaneous transmission of multiple data, ensuring the stability, integrity, and timing consistency of multi-channel power measurement data transmission, and providing a reliable data foundation for subsequent processing devices to perform time alignment processing.

[0010] Secondly, a power consumption measurement method is provided, which is applied to a processing unit in a satellite positioning device. The satellite positioning device further includes a transmitting unit, a data bus, multiple power-consuming devices, and multiple power consumption measurement devices. Each power consumption measurement device is used to measure the power consumption of a power-consuming device. Each power consumption measurement device is connected to the data bus, and the data bus is also connected to the transmitting unit. The transmitting unit is also connected to the processing unit. The method includes: the processing unit acquiring measurement data packets from the multiple power consumption measurement devices of the transmitting unit; the processing unit performing time alignment processing on the measurement data packets of the multiple power consumption measurement devices to obtain a set of power consumption measurement values ​​for each power consumption acquisition time in multiple power consumption acquisition times; the set of power consumption measurement values ​​includes multiple power consumption measurement values, and each power consumption measurement value corresponds to one power consumption measurement device.

[0011] The processing device performs time alignment processing on the received multi-channel measurement data packets, integrates the power consumption data corresponding to different power consumption measurement devices at the same measurement time into a set of power consumption measurement values, thereby completely obtaining the power consumption information of multiple power-consuming devices in the same time dimension, and finally realizing the synchronous measurement and effective integration of the power consumption of multiple power-consuming devices of the satellite positioning device.

[0012] In conjunction with the second aspect, in some embodiments of the second aspect, the processing device performs time alignment processing on the measurement data packets of multiple power consumption measurement devices to obtain a set of power consumption measurement values ​​for each power consumption acquisition time among multiple power consumption acquisition times, including: determining a target power consumption measurement device among the multiple power consumption measurement devices; the target power consumption measurement device is the power consumption measurement device with the smallest measurement interval among the multiple power consumption measurement devices, the measurement interval being the duration between power consumption measurement times in two adjacent measurement data packets acquired by the power consumption measurement device, and the multiple power consumption acquisition times being the power consumption measurement times in the multiple power consumption measurement data packets acquired by the target power consumption measurement device; for each power consumption measurement device to be aligned among the multiple power consumption measurement devices to be aligned, according to the power consumption measurement times in the multiple measurement data packets acquired by the power consumption measurement device to be aligned, the power consumption measurement values ​​in the multiple measurement data packets acquired by the power consumption measurement device to be aligned are time aligned with the power consumption measurement values ​​in the multiple measurement data packets acquired by the target power consumption measurement device to obtain a set of power consumption measurement values ​​for each power consumption acquisition time among the multiple power consumption acquisition times.

[0013] This technical solution uses the measurement time of the target power consumption measuring device with the smallest measurement interval as the unified power consumption acquisition time. The power consumption measurement values ​​of other power consumption measuring devices to be aligned are time-aligned with it. This can unify the power consumption measurement data of multiple channels with different sampling frequencies and acquisition times under the same time reference, eliminate the differences in the time dimension of each measurement data, and achieve accurate time synchronization and normalization integration of multiple power consumption data. This allows for the accurate acquisition of complete power consumption information of all power-consuming devices at each unified acquisition time, improving the time consistency and data validity of multi-channel power consumption measurement results.

[0014] In conjunction with the second aspect, in some embodiments of the second aspect, based on the power measurement times in the multiple measurement data packets collected by the power measurement device to be aligned, the power measurement values ​​in the multiple measurement data packets collected by the power measurement device to be aligned are time-aligned with the power measurement values ​​in the multiple measurement data packets collected by the target power measurement device to obtain a set of power measurement values ​​for each power acquisition time among the multiple power acquisition times. This includes: for each measurement data packet collected by the power measurement device to be aligned, determining the offset time between the power measurement time in the measurement data packet and the target power acquisition time; the target power acquisition time is the power acquisition time with the shortest time interval between the power measurement time in the measurement data packet and the power measurement time in the multiple power acquisition times; aligning the power measurement values ​​in the measurement data packet with the target power acquisition time according to the offset time corresponding to the measurement data packet to obtain a set of power measurement values ​​for each power acquisition time among the multiple power acquisition times.

[0015] This technical solution calculates the offset time between the power measurement time of the power measurement device to be aligned and the nearest target power acquisition time, and aligns the corresponding power measurement value to the target power acquisition time based on the offset time. This enables fine-grained time alignment of multi-channel power measurement data even when the sampling times of various measurement devices are inconsistent. It effectively reduces data errors caused by asynchronous sampling times, improves the matching accuracy and fusion reliability of multi-channel power data under a unified time reference, and provides accurate and reliable data support for the precise analysis and evaluation of multi-channel power consumption of satellite positioning devices.

[0016] In conjunction with the second aspect, in some embodiments of the second aspect, aligning the power consumption measurement value in the measurement data packet with the target power consumption acquisition time according to the offset duration corresponding to the measurement data packet to obtain a power consumption measurement value set for each power consumption acquisition time among multiple power consumption acquisition times includes: when the offset duration corresponding to the measurement data packet is greater than a preset duration threshold, determining the interpolated power consumption measurement value corresponding to the measurement data packet based on interpolation and the power consumption measurement value in the measurement data packet; aligning the interpolated power consumption measurement value with the target power consumption acquisition time to obtain a power consumption measurement value set for each power consumption acquisition time among multiple power consumption acquisition times; when the offset duration corresponding to the measurement data packet is less than or equal to the preset duration threshold, aligning the power consumption measurement value in the measurement data packet with the target power consumption acquisition time to obtain a power consumption measurement value set for each power consumption acquisition time among multiple power consumption acquisition times.

[0017] This technical solution sets a preset duration threshold. For measurement data packets with an offset duration greater than the threshold, it uses interpolation to calculate the corresponding interpolated power consumption measurement value. For measurement data packets with an offset duration less than or equal to the threshold, it directly performs alignment processing. It can adaptively select an appropriate alignment method according to the degree of offset at the measurement time. While ensuring the time alignment accuracy of multi-channel power consumption measurement data, it reduces unnecessary interpolation calculations, and balances the accuracy and processing efficiency of power consumption data alignment. This effectively improves the rationality and reliability of time alignment processing for multi-channel power consumption data.

[0018] Thirdly, a power consumption measurement system is provided, deployed in a satellite positioning device. The system includes a transmitting device, a processing device, a data bus, multiple power-consuming devices, and multiple power consumption measurement devices. Each power consumption measurement device measures the power consumption of one power-consuming device. Each power consumption measurement device is connected to the data bus, which is also connected to the transmitting device. The transmitting device is also connected to the processing device. The method includes: the transmitting device receiving measurement data packets collected by each of the multiple power consumption measurement devices; the measurement data includes the device number of the power consumption measurement device, the power consumption measurement value, and the power consumption measurement time; the transmitting device determining whether the number of measurement data packets received at the same time is multiple; if the number of measurement data packets received at the same time is multiple, the transmitting device determining the transmission order of the multiple measurement data packets received at the same reception time based on the device number in the multiple measurement data packets received at the same reception time; the transmitting device sending the multiple measurement data packets received at the same reception time to the processing device based on the transmission order; the processing device performing time alignment processing on the measurement data packets of the multiple power consumption measurement devices to obtain a set of power consumption measurement values ​​for each power consumption acquisition time among the multiple power consumption acquisition times; the set of power consumption measurement values ​​includes multiple power consumption measurement values, with each power consumption measurement value corresponding to one power consumption measurement device.

[0019] By configuring a dedicated power consumption measurement device for each power-consuming device in the satellite positioning system, a one-to-one independent measurement architecture is constructed. This hardware-level approach ensures that the power consumption of multiple power-consuming devices can be collected simultaneously and independently. Each power consumption measurement device uploads a data packet carrying the device number, power consumption measurement value, and measurement time in parallel via a data bus, providing the basic hardware and transmission support for multi-channel power consumption measurement. The transmitting device identifies the scenario of concurrent data transmission by judging the number of measurement data packets received at the same time and determines the ordered transmission sequence based on the device number in the data packet. This effectively avoids conflicts and errors caused by simultaneous transmission of multiple data, ensuring that all measurement data can be transmitted completely and orderly to the subsequent processing device. The processing device performs time alignment processing on the received multi-channel measurement data packets, integrating the power consumption data corresponding to different power consumption measurement devices at the same measurement time into a set of power consumption measurement values. This allows for the complete acquisition of power consumption information of multiple power-consuming devices in the same time dimension, ultimately achieving synchronous measurement and effective integration of the power consumption of multiple power-consuming devices in the satellite positioning system.

[0032] Satellite positioning equipment has been widely used in many fields such as vehicle navigation, Internet of Things terminals, and wearable positioning devices. Its power consumption performance directly determines the device's battery life, power supply design, and overall reliability, and is a core technical indicator in the research and development and performance optimization of satellite positioning terminals.

[0035] To address the aforementioned problems, this application provides a power consumption measurement method applied to a satellite positioning device. The satellite positioning device includes a processing unit, a transmitting unit, a data bus, multiple power-consuming devices, and multiple power consumption measurement devices. Each power consumption measurement device measures the power consumption of one power-consuming device. Each power consumption measurement device is connected to the data bus, which is also connected to the transmitting unit. The transmitting unit is also connected to the processing unit. The method includes: the transmitting unit receiving measurement data packets collected by each of the multiple power consumption measurement devices; the measurement data includes the device number of the power consumption measurement device, the power consumption measurement value, and the power consumption measurement time; the transmitting unit determining whether the number of measurement data packets received at the same time is multiple; if the number of measurement data packets received at the same time is multiple, the transmitting unit determining the transmission order of the multiple measurement data packets received at the same reception time based on the device number in the multiple measurement data packets received at the same reception time; the transmitting unit transmitting the multiple measurement data packets received at the same reception time to the processing unit based on the transmission order; the processing unit performing time alignment processing on the measurement data packets from the multiple power consumption measurement devices to obtain a set of power consumption measurement values ​​for each power consumption acquisition time among the multiple power consumption acquisition times; the set of power consumption measurement values ​​includes multiple power consumption measurement values, with each power consumption measurement value corresponding to one power consumption measurement device.

[0036] Based on this scheme, a one-to-one independent measurement architecture is constructed by configuring a corresponding power consumption measurement device for each power-consuming device in the satellite positioning device. This hardware-level approach ensures that the power consumption of multiple power-consuming devices can be collected simultaneously and independently. Each power consumption measurement device uploads a data packet carrying the device number, power consumption measurement value, and measurement time in parallel via a data bus, providing basic hardware and transmission support for multi-channel power consumption measurement.

[0037] Figure 1 This is a schematic diagram of the architecture of a satellite positioning device provided in this application. The technical solutions of the embodiments of this application can be applied to... Figure 1 The satellite positioning device shown, such as Figure 1As shown, the satellite positioning device 10 includes a processing device 101, a transmitting device 102, a data bus 103, multiple power-consuming devices 104, and multiple power consumption measuring devices 105.

[0038] Among them, a power consumption measuring device 105 is used to measure the power consumption of a power-consuming device 104. Each power consumption measuring device 105 is connected to a data bus 103, which is also connected to a transmitting device 102, which is also connected to a processing device 101.

[0039] The processing device 101 and the transmitting device 102 are used to execute the power consumption measurement method provided in this application. For a detailed description, please refer to the relevant description in the following section of the specific embodiments of this application.

[0040] The data bus 103 is a parallel or serial communication line used in satellite positioning equipment for transmitting data between chips, modules, and peripherals. As an information transmission channel of the hardware system, it realizes data interaction and instruction transmission between processors, storage devices, interface circuits, and external devices. It is the core hardware path to ensure that the functional components work together and complete information exchange.

[0041] The power-consuming device 104 is a device that consumes electrical energy in the satellite positioning device 10. It can be various functional modules in the satellite positioning device 10. For example, the power-consuming device 104 can be a radio frequency module, a satellite signal receiving module, or a satellite signal decoding module. Of course, the power-consuming device 104 can also be other modules. This application does not make any specific restrictions on this.

[0042] The power consumption measurement device 105 is a high-precision power supply measurement instrument. By connecting a precision sampling resistor or a current probe in series, it captures the transient current and voltage of the power-consuming device 104 in different working states such as capture, tracking, and standby in real time, and obtains dynamic power consumption data through high-speed sampling and calculation.

[0043] In the above connection relationship, a wired connection or a wireless connection can be used, and the embodiments of this application do not limit the connection.

[0044] Figure 2 A flowchart illustrating a power consumption measurement method provided in this application is shown below. Figure 2 As shown, the method includes the following steps: S201, The transmitting device receives the measurement data packets collected by each of the multiple power consumption measuring devices.

[0045] The measurement data includes the device number of the power consumption measurement device, the power consumption measurement value, and the power consumption measurement time.

[0046] The device number can be 01, 02, 03, etc., or it can be A, B, C, etc. This application does not impose any specific restrictions on this.

[0047] As one possible implementation, after the power consumption measuring device measures a power consumption value from the power-consuming module, it encapsulates the device number, the power consumption value, and the measurement time into a measurement data packet and sends it to the transmitting device via the data bus. Correspondingly, the transmitting device receives the measurement data packet from the power consumption measuring device via the data bus.

[0048] S202, The transmitting device determines whether there are multiple measurement data packets received at the same time.

[0049] As one possible implementation, after receiving each measurement data packet, the transmitting device determines whether other measurement data packets have been received at the same time.

[0050] If other measurement data packets are received at the same time, it is determined that the number of measurement data packets received at the same time is multiple.

[0051] If it is determined that there are multiple measurement data packets received at the same time, the transmitting device performs S203.

[0052] If no other measurement data packets are received at the same time, the number of measurement data packets received at the same time is determined to be 1.

[0053] If it is determined that the number of measurement data packets received at the same time is 1, the transmitting device sends the measurement data packet to the processing device.

[0054] S203. When multiple measurement data packets are received at the same time, the transmitting device determines the transmission order of the multiple measurement data packets received at the same time based on the device number in the multiple measurement data packets received at the same time.

[0055] As one possible implementation, when multiple measurement data packets are received at the same time, the transmitting device sorts the device numbers in the multiple measurement data packets received at the same receiving time to obtain a sorting result of multiple device numbers; the sorting result of multiple device numbers is used as the transmission order of the multiple measurement data packets received at the same receiving time.

[0056] As an example, if multiple measurement data packets are received at the same time, and the device numbers of the multiple measurement data packets are 01, 02, and 03 respectively, the sending device will sort 01, 02, and 03, and the sorting result will be 01, 02, and 03.

[0057] The transmitting device uses 01, 02, and 03 as the transmission order for multiple measurement data packets, that is, it first sends the measurement data packet corresponding to 01, then sends the measurement data packet corresponding to 02, and finally sends the measurement data packet corresponding to 03.

[0058] It should be noted that this example sorts the devices in ascending order of their device numbers. In other embodiments, the devices may be sorted in descending order of their device numbers. This application does not impose any specific restrictions on this.

[0059] Based on this possible implementation, by sorting the device numbers in multiple measurement data packets received at the same time and using the sorting result as the sending order of the corresponding measurement data packets, it is possible to achieve standardized and orderly scheduling of data packet sending order when multiple power measurement data are transmitted concurrently. This avoids data conflicts, packet loss, and timing disorder caused by simultaneous transmission of multiple data, ensuring the stability, integrity, and timing consistency of multi-channel power measurement data transmission, and providing a reliable data foundation for subsequent processing devices to perform time alignment processing.

[0060] S204. The transmitting device sends multiple measurement data packets received at the same receiving time to the processing device based on the transmitting order.

[0061] As one possible implementation, taking the sorting result as 01, 02, 03 as an example, the transmitting device first sends the measurement data packet corresponding to 01, then sends the measurement data packet corresponding to 02, and finally sends the measurement data packet corresponding to 03.

[0062] S205. The processing device performs time alignment processing on the measurement data packets of multiple power consumption measurement devices to obtain a set of power consumption measurement values ​​for each power consumption acquisition time in multiple power consumption acquisition times.

[0063] The power consumption measurement set includes multiple power consumption measurement values, with each power consumption measurement value corresponding to a power consumption measurement device.

[0064] As one possible implementation, firstly, the processing device determines a target power consumption measuring device among multiple power consumption measuring devices; the target power consumption measuring device is the power consumption measuring device with the smallest measurement interval among the multiple power consumption measuring devices, the measurement interval is the duration between the power consumption measurement moments in two adjacent measurement data packets collected by the power consumption measuring device, and the multiple power consumption acquisition moments are the power consumption measurement moments in the multiple power consumption measurement data packets collected by the target power consumption measuring device.

[0065] As an example, for each of the multiple power consumption measurement devices, the processing device determines the duration between power consumption measurement moments in two adjacent measurement data packets collected by the power consumption measurement device, and identifies the power consumption measurement device with the shortest duration as the target power consumption measurement device.

[0066] The processing device uses the power measurement time in the measurement data packet collected by the target power consumption measurement device as the power acquisition time.

[0067] Secondly, for each of the multiple power measurement devices to be aligned, the processing device aligns the power measurement values ​​in the multiple measurement data packets collected by the power measurement device to be aligned with the power measurement values ​​in the multiple measurement data packets collected by the target power measurement device according to the power measurement time in the multiple measurement data packets collected by the power measurement device to be aligned, so as to obtain the power measurement value set of each power acquisition time in the multiple power acquisition time.

[0068] As an example, in the first step, for each of the multiple measurement data packets collected by the power consumption measurement device to be aligned, the processing device determines the offset time between the power consumption measurement time in the measurement data packet and the target power consumption acquisition time; the target power consumption acquisition time is the power consumption acquisition time with the shortest time interval between the multiple power consumption acquisition times and the power consumption measurement time in the measurement data packet.

[0069] Specifically, the processing device finds the power acquisition time with the shortest time interval between multiple power acquisition times and the power measurement times in the measurement data packet, and uses this power acquisition time as the target power acquisition time.

[0070] The processing device determines the duration between the power consumption measurement time and the target power consumption acquisition time, and uses this duration as the offset duration.

[0071] The second step involves the processing device aligning the power consumption measurement values ​​in the measurement data packet with the target power consumption acquisition time based on the offset duration corresponding to the measurement data packet, thereby obtaining a set of power consumption measurement values ​​for each power consumption acquisition time among multiple power consumption acquisition times.

[0072] Specifically, the processing device determines whether the offset duration corresponding to the measurement data packet is greater than a preset duration threshold.

[0073] When the offset duration corresponding to the measurement data packet is greater than the preset duration threshold, the processing device determines the interpolated power measurement value corresponding to the measurement data packet based on the interpolation method and the power measurement value in the measurement data packet. Then, the interpolated power measurement value is aligned with the target power acquisition time to obtain the power measurement value set for each power acquisition time among multiple power acquisition times.

[0074] For example, the processing device determines the interpolated power measurement value corresponding to the target power acquisition time by interpolation based on the power measurement value and power measurement time in the measurement data packet, as well as the power measurement value and power measurement time in the previous measurement data packet, and aligns the interpolated power measurement value with the target power acquisition time.

[0075] It should be noted that the specific scheme for determining the interpolated power consumption measurement value by interpolation method can refer to existing schemes, and will not be described in detail here.

[0076] When the offset duration corresponding to the measurement data packet is less than or equal to the preset duration threshold, the processing device aligns the power consumption measurement value in the measurement data packet with the target power consumption acquisition time to obtain a set of power consumption measurement values ​​for each power consumption acquisition time among multiple power consumption acquisition times.

[0077] Understandably, when the offset duration corresponding to the measurement data packet is less than or equal to the preset duration threshold, the processing device directly aligns the power consumption measurement value in the measurement data packet with the target power consumption acquisition time.

[0078] After performing the above processing on each measurement data packet collected by each power consumption measurement device, the processing device can obtain the power consumption measurement value set for each power consumption acquisition time in multiple power consumption acquisition times.

[0079] Based on this specific solution, the technical solution sets a preset duration threshold. For measurement data packets with an offset duration greater than the threshold, interpolation is used to calculate the corresponding interpolated power consumption measurement value. For measurement data packets with an offset duration less than or equal to the threshold, alignment processing is performed directly. This solution can adaptively select an appropriate alignment method according to the degree of offset at the measurement time. While ensuring the time alignment accuracy of multi-channel power consumption measurement data, it reduces unnecessary interpolation calculations, thus balancing the accuracy and processing efficiency of power consumption data alignment. This effectively improves the rationality and reliability of time alignment processing for multi-channel power consumption data.

[0080] Based on this exemplary solution, the technical solution calculates the offset time between the power measurement time of the power measurement device to be aligned and the nearest target power acquisition time, and aligns the corresponding power measurement value to the target power acquisition time according to the offset time. This enables fine-grained time alignment of multi-channel power measurement data even when the sampling times of various measurement devices are inconsistent. It effectively reduces data errors caused by asynchronous sampling times, improves the matching accuracy and fusion reliability of multi-channel power data under a unified time reference, and provides accurate and reliable data support for the precise analysis and evaluation of multi-channel power consumption of satellite positioning devices.

[0081] Based on this possible implementation method, the technical solution uses the measurement time of the target power consumption measuring device with the smallest measurement interval as the unified power consumption acquisition time, and performs time alignment processing on the power consumption measurement values ​​of other power consumption measuring devices to be aligned with it. This can unify the power consumption measurement data of multiple channels with different sampling frequencies and acquisition times under the same time reference, eliminate the differences in the time dimension of each measurement data, realize the accurate time synchronization and normalization integration of multiple power consumption data, thereby accurately obtaining the complete power consumption information of all power-consuming devices at each unified acquisition time, and improving the time consistency and data validity of multiple power consumption measurement results.

[0082] Based on S201-S205, a one-to-one independent measurement architecture is constructed by configuring a corresponding power consumption measurement device for each power-consuming device in the satellite positioning device. This hardware-level hardware ensures that the power consumption of multiple power-consuming devices can be collected simultaneously and independently. Each power consumption measurement device uploads a data packet carrying the device number, power consumption measurement value, and measurement time in parallel via a data bus, providing basic hardware and transmission support for multi-channel power consumption measurement. The transmitting device identifies the scenario of concurrent data transmission by judging the number of measurement data packets received at the same time and determines the orderly transmission order based on the device number in the data packet. This effectively avoids conflicts and errors caused by simultaneous transmission of multiple data, ensuring that all measurement data can be transmitted completely and orderly to the subsequent processing device. The processing device performs time alignment processing on the received multi-channel measurement data packets, integrating the power consumption data corresponding to different power consumption measurement devices at the same measurement time into a set of power consumption measurement values. This allows for the complete acquisition of power consumption information of multiple power-consuming devices in the same time dimension, ultimately achieving synchronous measurement and effective integration of the power consumption of multiple power-consuming devices in the satellite positioning device.
