[0033] It is understood that the "embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, the various embodiments in the entire specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It is understood that in various embodiments of the present application, the size of the sequence number of each process does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0035] It can be understood that some optional features in the embodiments of the present application may be implemented independently in certain scenarios without relying on other features, such as the solution on which they are currently based, to solve corresponding technical problems and achieve corresponding effects, or may be combined with other features according to needs in certain scenarios. Accordingly, the devices provided in the embodiments of the present application may also realize these features or functions accordingly, which will not be elaborated here.
[0036] In this application, unless otherwise specified, the same or similar parts between the various embodiments can refer to each other. In the various embodiments in this application, and the various implementation methods in each embodiment, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments and the various implementation methods in each embodiment are consistent and can be referenced to each other. The technical features in different embodiments and the various implementation methods in each embodiment can be combined to form new embodiments, implementation methods, implementation methods, or implementation methods according to their inherent logical relationships. The following implementation methods of this application do not constitute a limitation on the scope of protection of this application.
[0037] Electronic devices generate power consumption when they are running. For example, the positioning chip of a satellite signal receiver has multiple operating conditions when it is running (for example, capturing satellite signals, tracking satellite signals, positioning, sleep, wake-up, ephemeris injection, RTK solution, RD combined inertial navigation, etc.). Under different operating conditions, the power consumption of the positioning chip will also be different.
[0038] The existing solution has the problem that the measured power consumption value of the electronic device is not aligned with the time. For example, the power consumption value of the electronic device is measured to be 5W at 10:00:00 on January 1, 2024. 5W should be corresponded to 10:00:00 on January 1, 2024. In some cases, 5W will be corresponded to 10:00:01 on January 1, 2024, resulting in the power consumption value of the measured electronic device not being aligned with the time.
[0039] To solve the above problems, the present application provides a time alignment method, which can be applied to a time alignment system. Figure 1 This is a schematic diagram of the architecture of a time alignment system provided by the present application. The technical solution of the embodiment of the present application can be applied to Figure 1 The time alignment system shown, such as Figure 1 As shown, the time alignment system 10 includes a measuring device 11 and an electronic device 12 .
[0040] The measuring device 11 is used to measure the power consumption value of the electronic device, and the measuring device 11 may be a power consumption measurement chip.
[0041] The electronic device 12 may include a timer, a plurality of event control registers and a plurality of data registers. The timer may count, the event control register may execute a preset processing logic after being triggered, and the data register may store data.
[0042] The electronic device 12 may be a GNSS positioning chip, or the electronic device 12 may be a receiver including a GNSS positioning chip. Of course, the electronic device 12 may also be other devices, and this application does not impose any specific limitation on this.
[0043] The measuring device 11 is directly or indirectly connected to the electronic device 12 . In this connection relationship, a wired connection or a wireless connection may be adopted, which is not limited in the embodiment of the present application.
[0044] The measuring device 11 and the electronic device 12 can exchange data.
[0045] It should be noted that the measuring device 11 and the electronic device 12 may be independent devices or integrated into the same device, and this application does not make any specific limitation on this.
[0046] When the measuring device 11 and the electronic device 12 are integrated into the same device, the communication between the measuring device 11 and the electronic device 12 is the communication between the internal modules of the device. In this case, the communication process between the two is the same as "the communication process between the two when the measuring device 11 and the electronic device 12 are independent of each other".
[0047] In the following embodiments provided in the present application, the present application is described by taking the example that the measuring device 11 and the electronic device 12 are independently configured.
[0048] In practical applications, the time alignment method provided in the embodiment of the present application can be applied to the electronic device 12, and can also be applied to the device included in the electronic device 12.
[0049] The time alignment method provided in the embodiment of the present application is described below with reference to the accompanying drawings, taking the time alignment method applied to the electronic device 12 as an example.
[0050] Figure 2 A schematic diagram of a time alignment method provided in this application, which is applied to Figure 1 The electronic device shown includes a target timer, such as Figure 2 As shown, the method comprises the following steps:
[0051] S201: The electronic device triggers a first event in response to a first interrupt.
[0052] The measuring device generates a first interrupt after obtaining the target power consumption value of the electronic device, and the first event is used to obtain first counting information of the target timer when the first interrupt is generated.
[0053] It should be noted that the target timer can run in free counting mode, which means that the target timer starts from the maximum value 0xFFFFFFFF, and automatically decreases by one after receiving a pulse from the clock source until it automatically returns to the maximum value and continues to run after decreasing to 0. The clock source of the target timer can be the external TCXO of the electronic device, with an accuracy of 1ppm, that is, there will be a maximum error of 1us per second.
[0054] Exemplarily, the first counting information may be 0x9495843, 0x9495833, or 0x9495863. Of course, the first counting information may be other values, and the present application does not impose any specific limitation on this.
[0055] As a possible implementation manner, the electronic device includes a first event control register and a first data register. After receiving the first interrupt, the electronic device triggers the first event control register in response to the first interrupt.
[0056] The first event control register is used to take a snapshot of the target timer, obtain first counting information of the target timer, and save the first counting information to the first data register.
[0057] Based on this possible implementation method, compared with triggering the first event by software, the first event is triggered by triggering the first event control register. Since the event control register is triggered at the hardware level, the hardware processing speed is faster. After the first interrupt is generated, the target timer can be snapshotted quickly to obtain the first counting information, thereby improving the accuracy of the first counting information.
[0058] S202: The electronic device obtains first information.
[0059] The first information includes the second counting information of the target timer at the first moment and the first UTC at the first moment, and the first moment is before the generation moment of the first interrupt.
[0060] Exemplarily, the second counting information may be 0x9496843, 0x9595833, or 0x9695863. Of course, the second counting information may be other values, and the present application does not impose any specific limitation on this.
[0061] As a possible implementation manner, the electronic device obtains the first information input by the external device from its own input device.
[0062] As another possible implementation, the electronic device includes a second data register and a third data register, the second data register is used to store the second counting information of the target timer at the first moment, and the third data register is used to store the first UTC at the first moment.
[0063] The electronic device obtains the second counting information from the second data register and obtains the first UTC from the third data register.
[0064] S203: The electronic device determines a second UTC according to the first counting information, the second counting information, and the first UTC.
[0065] The second UTC is the time when the measuring device obtains the target power consumption value.
[0066] As a possible implementation manner, the electronic device determines a target duration, and uses the sum of the first UTC and the target duration as the second UTC.
[0067] The target duration is the product of the target difference and the clock source frequency of the target timer, and the target difference is the difference between the first counting information and the second counting information.
[0068] In this possible implementation, since the first UTC corresponds to the second counting information, after determining the product of the target difference and the clock source frequency of the target timer, that is, the target duration, the sum of the first UTC and the target duration can be used as the second UTC.
[0069] Based on S201-S203, after the measuring device connected to the electronic device obtains the target power consumption value of the electronic device and generates a first interrupt, the electronic device triggers a first event for obtaining first counting information of the target timer in the electronic device when the first interrupt is generated by responding to the first interrupt, and then obtains first information including second counting information of the target timer at the first moment and first UTC at the first moment. Since the first information at the first moment is before the moment when the first interrupt is generated, the second UTC corresponding to the moment when the measuring device obtains the target power consumption value can be determined based on the first counting information, the second counting information and the first UTC, so that the power consumption value of the measured electronic device can be aligned with the moment.
[0070] The above is a general description of the time alignment method provided in the present application. The time alignment method provided in the present application will be further described below in conjunction with the accompanying drawings.
[0071] In one design, the time alignment method provided by the present application may further include the following steps:
[0072] S301: The electronic device triggers a second event and a third event in response to a second interrupt at a first moment.
[0073] Among them, the electronic device generates a second interrupt after outputting the PPS signal, the second event is used to save the second counting information of the target timer at the first moment to the second data register, and the third event is used to save the first UTC at the first moment to the third data register.
[0074] It should be noted that the frequency of the PPS signal can be 1 Hz-10 Hz, and this application does not impose any specific limitation on this.
[0075] The error of the PPS signal can be less than 50ns.
[0076] As a possible implementation, for the second event, the electronic device includes a second event control register, the second data register includes a counting information storage area, the counting information storage area is used to store the counting information of the target timer, and the electronic device triggers the second event control register in response to the second interrupt at the first moment.
[0077] The second event control register is used to take a snapshot of the target timer, obtain the second counting information of the target timer, clear the data in the counting information storage area of the second data register, and save the second counting information to the counting information storage area of the second data register.
[0078] Based on this, on the one hand, compared with triggering the second event by software, triggering the second event control register to trigger the second event, because the event control register is triggered at the hardware level, the hardware processing speed is faster, and after the second interrupt is generated, the target timer can be snapshotted quickly to obtain the second counting information, thereby improving the accuracy of the second counting information. On the other hand, before the second counting information is saved to the counting information storage area of the second data register, the data in the counting information storage area of the second data register is cleared, and the data stored in the counting information storage area of the second data register can be updated, thereby reducing the difference between the first counting information and the second counting information, and reducing the error of the second UTC.
[0079] For the third event, the electronic device includes a third event control register, the third data register includes a UTC storage area, the UTC storage area is used to store UTC, and the electronic device triggers the third event control register.
[0080] The third event control register is used to obtain the first UTC, clear the data in the UTC storage area of the third data register, and save the first UTC to the UTC storage area of the third data register.
[0081] Based on this, compared to triggering the third event by software, the third event is triggered by triggering the third event control register. Since the event control register is triggered at the hardware level, the hardware processing speed is faster. After the second interrupt occurs, the first UTC can be stored in the UTC storage area of the third data register more quickly.
[0082] It should be noted that the electronic device can execute S301 and S201 - S203 in parallel.
[0083] In one design, after the electronic device obtains multiple second UTCs, it can generate multiple data packets, each of which includes multiple second information, and the second information includes the second UTC, the power consumption value corresponding to the second UTC, the voltage value corresponding to the power consumption value, the current value corresponding to the power consumption value, the data packet header, the data packet check code and other information.
[0084] It should be noted that the data volume of the data packet can be 15 bytes to 25 bytes.
[0085] The second UTCs in the plurality of second information in the data packet are adjacent, so that the temporal continuity of the data in the data packet can be improved.
[0086] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the electronic device executing the time alignment method. In order to achieve the above functions, the electronic device includes a hardware structure and / or software module corresponding to the execution of each function. It should be easily appreciated by those skilled in the art that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the embodiments of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of this application.
