Description

[0002] Because the voltage and current data of the power supply unit fluctuate in real time, accurate analysis of the power consumption of the power supply unit requires the synchronous collection of power data from each node of the power supply unit. Currently, during the synchronous collection of power data from each node of the power supply unit, the acquisition unit begins collecting data after receiving an instruction and sends the collected data to the main controller after completion. During this process, multiple acquisition units may send data to the main controller simultaneously, leading to transmission channel congestion or data conflicts with the main controller, resulting in low data acquisition efficiency.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0048] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0049] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0050] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0052] Because the voltage and current data of the power supply unit fluctuate in real time, it is extremely important to synchronously collect the power data of each node of the power supply unit when it is necessary to accurately analyze the energy consumption of the power supply unit.

[0053] The relevant technologies for data acquisition include: Method 1, acquiring data through multi-channel parallel data acquisition; and Method 2, acquiring data through single-channel serial data acquisition. The following sections will provide detailed explanations of Methods 1-2 respectively.

[0054] Method 1: Data is acquired through multi-channel parallel data acquisition, specifically including: Figure 1 As shown, a data transmission channel is configured between the main controller and each data acquisition unit. The main controller communicates with each data acquisition unit simultaneously, sending synchronous acquisition information. After receiving the synchronization pulse command, each data acquisition unit starts data acquisition simultaneously, and then synchronously returns the data acquired by each data acquisition unit to the main controller through the transmission channel between the main controller and the main controller.

[0055] In Method 1, each data acquisition unit involves two processes: receiving a synchronization command and immediately responding by returning the acquired data to the main controller via its corresponding data acquisition channel. While Method 1 ensures data synchronization, the main controller only needs to acquire data collected at the "same time point," not simultaneously. Therefore, Method 1 suffers from wasted channel resources. Furthermore, in Method 1, each data acquisition unit immediately returns the acquired data to the main controller after collection. Consequently, data acquisition via Method 1 can lead to data conflicts or congestion at the main controller, resulting in low data acquisition efficiency.

[0056] In addition to method 1 mentioned above, related technologies also propose method 2, which involves acquiring data through a single-channel serial data acquisition method.

[0057] Method 2: Data is acquired via a single-channel serial data acquisition method, specifically including: the main controller connects to multiple data acquisition units through a single data transmission channel; such as... Figure 2 As shown, based on the first synchronization pulse signal, each data acquisition unit initiates a data acquisition command. Then, based on subsequent synchronization pulse signals, each data acquisition unit begins to return the acquired data. The main controller parses the data from each data acquisition unit according to the specific order of the synchronization signals.

[0058] Method 2 obtains synchronization information from all data acquisition units through a single data channel, solving the channel resource waste problem in Method 1 and saving data channels. However, in Method 2, each data acquisition unit immediately returns the acquired data to the main controller after acquisition. Therefore, data acquisition via Method 2 still suffers from data conflicts or congestion at the main controller, resulting in low data acquisition efficiency.

[0059] Therefore, the single-channel data acquisition system provided in this application first sends synchronous data acquisition signals to multiple data acquisition units, instructing them to acquire target data. Then, in response to the synchronous data acquisition signals, each data acquisition unit acquires the target data and sends it to the main controller at the corresponding target time point. Finally, the main controller receives the target data from the data acquisition units. Compared to current data acquisition technologies that suffer from data conflicts or congestion at the main controller, the above solution avoids multiple data conflicts or congestion at the main controller by controlling each data acquisition unit to send target data to the main controller at the corresponding target time point, thereby significantly improving the efficiency of the data acquisition system.

[0060] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0061] Figure 3 This is an architecture diagram of a single-channel data acquisition system 30 provided in an embodiment of this application. Figure 3 As shown, the single-channel data acquisition system 30 includes a main controller 301 and a data acquisition unit 302.

[0062] The data acquisition unit 302 can be one or more.

[0063] The main controller 301 and the data acquisition unit 302 are connected via a communication link. This communication link can be a wired communication link or a wireless communication link, and this application does not limit it in this way.

[0064] The main controller 301 is configured to send synchronous data acquisition signals to multiple data acquisition units 302. These synchronous data acquisition signals instruct the data acquisition units 302 to acquire target data.

[0065] In one possible implementation, the main controller 301 sends a synchronization pulse signal to multiple data acquisition units 302 via a serial digital interface, instructing the multiple data acquisition units 302 to acquire target data respectively.

[0066] The data acquisition unit 302 is configured to: acquire target data in response to the synchronous data acquisition signal; and send the target data to the main controller 301 at the corresponding target time point.

[0067] One data acquisition unit 302 corresponds to one target time point.

[0068] One possible implementation is that, upon receiving a synchronization pulse signal, multiple data acquisition units 302 simultaneously acquire target data in response to the synchronization pulse signal.

[0069] Optionally, the synchronization error of the data acquisition unit 302 in acquiring the target data is less than or equal to a preset threshold.

[0070] For example, the synchronization error of the data acquisition unit 302 in acquiring the target data is less than or equal to 10 microseconds.

[0071] One possible implementation is that after multiple data acquisition units 302 acquire the target data, they send the target data to the main controller 301 sequentially through a single data transmission channel according to the corresponding target time point.

[0072] For example, such as Figure 4 As shown, taking multiple data acquisition units, including data acquisition unit A, data acquisition unit B, and data acquisition unit C, as an example, in the target data transmission channel, data acquisition unit A sends target data A to the main controller 301 at 00:00:01, data acquisition unit B sends target data B to the main controller 301 at 00:00:02, and data acquisition unit C sends target data C to the main controller 301 at 00:00:03.

[0073] The main controller 301 is also configured to receive the plurality of target data.

[0074] For example, the main controller 301 receives target data A from data acquisition unit A, target data B from data acquisition unit B, and target data C from data acquisition unit C.

[0075] Based on the above technical solution, the single-channel data acquisition system provided in this application first sends a synchronous data acquisition signal to multiple data acquisition units 302, instructing the data acquisition units 302 to acquire target data. Then, in response to the synchronous data acquisition signal, each data acquisition unit 302 acquires the target data and sends it to the main controller 301 at the corresponding target time point. Finally, the main controller 301 receives the target data from the data acquisition units 302. Compared to current data acquisition technologies that suffer from data conflicts or congestion at the main controller, the above technical solution avoids multiple data conflicts or congestion at the main controller 301 by controlling each data acquisition unit 302 to send target data to the main controller 301 at the corresponding target time point, thereby greatly improving the efficiency of the data acquisition system.

[0076] The following describes in detail the process by which the main controller 301 sends the target data to each data acquisition unit 302 at the target time point.

[0077] The main controller 301 is also configured to: determine the target time point corresponding to each data acquisition unit 302; and send a first instruction to the multiple data acquisition units respectively.

[0078] The first instruction is used to instruct the data acquisition unit 302 to send target data to the main controller 301 at the corresponding target time point.

[0079] In one possible implementation, the main controller 301 sends the corresponding target time point and a first instruction to each data acquisition unit 302 through a serial digital interface, instructing the multiple data acquisition units 302 to send target data to the main controller 301 at the corresponding target time point.

[0080] For example, consider multiple data acquisition units, namely data acquisition unit A, data acquisition unit B, and data acquisition unit C, with target time points of 00:00:01, 00:00:02, and 00:00:03, respectively. The main controller 301 sends a first instruction to data acquisition unit A via a serial digital interface, instructing data acquisition unit A to send target data A to the main controller 301 at the corresponding target time point 00:00:01. The main controller 301 also sends a first instruction to data acquisition unit B via the serial digital interface, instructing data acquisition unit B to send target data B to the main controller 301 at the corresponding target time point 00:00:02. Finally, the main controller 301 sends a first instruction to data acquisition unit C via the serial digital interface, instructing data acquisition unit C to send target data C to the main controller 301 at the corresponding target time point 00:00:03.

[0081] The data acquisition unit 302 is configured to: receive a first instruction and determine the corresponding target time point based on the first instruction.

[0082] For example, data acquisition unit A receives a first instruction from the main controller 301 and determines 00:00:01 as the corresponding target time point. Data acquisition unit B receives a first instruction from the main controller 301 and determines 00:00:02 as the corresponding target time point. Data acquisition unit C receives a first instruction from the main controller 301 and determines 00:00:03 as the corresponding target time point.

[0083] Based on the above technical solution, the main controller 301 determines the target time point corresponding to each data acquisition unit and sends a first instruction to each of the multiple data acquisition units 302. Since the first instruction instructs the data acquisition units 302 to send target data to the main controller 301 at the corresponding target time point, in this technical solution, the main controller 301 controls the time when multiple target data arrive at the main controller 301 by controlling the time when the data acquisition units 302 send the target data to the main controller 301. This avoids multiple data conflicts or congestion at the main controller 301, thereby greatly improving the efficiency of the data acquisition system.

[0084] The following describes in detail the process by which the main controller 301 determines the target time point for each data acquisition unit 302.

[0085] The main controller 301 is also configured to: determine the transmission time interval based on the preset period and the total number of data acquisition units 302; determine the transmission order of each data acquisition unit 302; determine the target time point based on the transmission time interval and the transmission order; and the time interval between two adjacent target time points is less than or equal to the ratio of the preset period to the total number of data acquisition units 302.

[0086] In one possible implementation, the main controller 301 determines the ratio of a preset period to the total number of data acquisition units 302, and determines that the time interval between the transmission of target data by multiple data acquisition units 302 is less than the ratio.

[0087] For example, taking a preset period of 4 seconds and a total number of 3 data acquisition units 302 as an example. The main controller 301 determines that the ratio of the preset period of 4 seconds to the total number of 3 data acquisition units 3 is 4 / 3. The main controller 301 selects any value from the range [0, 3 / 4], for example, 1. The main controller 301 determines 1 second as the transmission time interval for multiple data acquisition units 302 to send target data.

[0088] In one possible implementation, the main controller 301 determines the target time point of each data acquisition unit 302 based on the preset transmission order and transmission time interval of multiple data acquisition units 302.

[0089] For example, consider multiple data acquisition units, namely data acquisition unit A, data acquisition unit B, and data acquisition unit C, with a preset transmission order of data acquisition unit A, data acquisition unit B, and data acquisition unit C. Since the main controller 301 determines 1 second as the transmission time interval, it determines the target time point for data acquisition unit A as 00:00:01, the target time point for data acquisition unit B as 00:00:02, and the target time point for data acquisition unit C as 00:00:03.

[0090] Based on the above technical solution, the main controller 301 determines the transmission time interval and the transmission order of each data acquisition unit 302 according to the preset period and the total number of data acquisition units 302, and determines the target time point based on the transmission time interval and transmission order. Since the first instruction is used to instruct the data acquisition units 302 to send target data to the main controller 301 at the corresponding target time point, and the time interval between two adjacent target time points is less than or equal to the ratio of the preset period to the total number of data acquisition units 302, the main controller 301, through the above technical solution, determines that the total time for multiple data acquisition units 302 to send target data to the main controller 301 is less than the preset period, avoiding multiple data conflicts or congestion at the main controller 301, thereby greatly improving the efficiency of the data acquisition system.

[0091] As one possible embodiment of this application, such as Figure 5 As shown, the main controller 301 also includes a computing unit 3011.

[0092] The computing unit 3011 is configured to process multiple target data.

[0093] One possible implementation is that the computing unit 3011 performs calculations on multiple target data.

[0094] In another possible implementation, the computing unit 3011 is also used to calculate the target time point for each data acquisition unit 302.

[0095] Based on the above technical solution, the main controller 301 also includes a computing unit 3011. After the main controller acquires multiple target data, the main controller 301 processes the multiple target data through the computing unit 3011, which facilitates data analysis by the staff.

[0096] When implemented in hardware, the various modules of the main controller 301, data acquisition unit 302, or computing unit 3011 in the single-channel data acquisition system 30 can be integrated onto an electronic device. Specifically, for example... Figure 6 As shown, the basic hardware structure of electronic devices is introduced.

[0097] Figure 6 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Figure 6 As shown, the electronic device includes at least one processor 601, a communication line 602, and at least one communication interface 604, and may also include a memory 603. The processor 601, memory 603, and communication interface 604 are connected via the communication line 602.

[0098] The processor 601 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this application, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0099] Communication line 602 may include a path for transmitting information between the aforementioned components.

[0100] The communication interface 604 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0101] The memory 603 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code having the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0102] In one possible design, the memory 603 can exist independently of the processor 601, meaning the memory 603 can be an external memory of the processor 601. In this case, the memory 603 can be connected to the processor 601 via a communication line 602 to store execution instructions or application code, and its execution is controlled by the processor 601 to implement the single-channel data acquisition method provided in the following embodiments of this application. In another possible design, the memory 603 can also be integrated with the processor 601, meaning the memory 603 can be an internal memory of the processor 601. For example, the memory 603 can be a cache, used to temporarily store some data and instruction information.

[0103] As one possible implementation, processor 601 may include one or more CPUs, for example Figure 6 CPU0 and CPU1 in the example. As another possible implementation, the electronic device may include multiple processors, such as... Figure 6 The processors 601 and 607 are included. As another possible implementation, the electronic device may also include an output device 605 and an input device 606.

[0104] It should be noted that the various embodiments of this application can be referenced or learned from each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can be referenced from each other without limitation.

Figure 7 As shown, the method includes the following steps: S701-S704.

[0110] One possible implementation is that, upon receiving a synchronization pulse signal, the data acquisition unit acquires target data in response to the synchronization pulse signal.

[0111] S703. Send target data to the main controller at the target time point corresponding to the data acquisition unit.

[0112] One possible implementation is that after the data acquisition unit acquires the target data, it sends the target data to the main controller through a single data transmission channel according to the corresponding target time point.

[0113] For example, in the target data transmission channel, data acquisition unit A sends target data A to the main controller at 00:00:01. Data acquisition unit B sends target data B to the main controller at 00:00:02. Data acquisition unit C sends target data C to the main controller at 00:00:03.

[0114] S704, the main controller receives data from multiple targets.

[0115] For example, the main controller 301 receives target data A from data acquisition unit A, target data B from data acquisition unit B, and target data C from data acquisition unit C.

[0116] Based on the above technical solution, the main controller sends synchronous data acquisition signals to multiple data acquisition units. The data acquisition units respond to these signals and acquire target data accordingly, achieving the goal of controlling multiple data acquisition units to acquire target data at the same time point. Furthermore, each data acquisition unit sends its target data to the main controller at its corresponding target time point, and the main controller receives multiple target data sets. Compared to current data acquisition technologies that suffer from data conflicts or congestion at the main controller, this technical solution avoids such problems by controlling each data acquisition unit to send its target data to the main controller at its corresponding target time point, thereby significantly improving the efficiency of the data acquisition system.

[0117] As one possible embodiment of this application, combined with Figure 7 ,like Figure 8 As shown, prior to S703 above, the process of determining the target time point for the data acquisition unit to send target data can also be implemented through the following S801-S803.

[0118] S801, the main controller determines the target time point corresponding to each data acquisition unit.

[0119] In one possible implementation, the main controller 301 sends the corresponding target time point to each data acquisition unit 302 via a serial digital interface.

[0120] For example, consider multiple data acquisition units, namely data acquisition unit A, data acquisition unit B, and data acquisition unit C, with target time points of 1s, 2s, and 3s respectively. The main controller 301 sends the target time point 1s to data acquisition unit A via a serial digital interface. The main controller 301 sends the target time point 2s to data acquisition unit B via a serial digital interface. The main controller 301 sends the target time point 3s to data acquisition unit C via a serial digital interface.

[0121] S802 and the main controller send first instructions to multiple data acquisition units respectively. Correspondingly, the data acquisition units receive the first instructions.

[0122] The first instruction is used to instruct the data acquisition unit to send target data to the main controller at the corresponding target time point.

[0123] In one possible implementation, the main controller 301 sends a first instruction to each data acquisition unit 302 via a serial digital interface, instructing the multiple data acquisition units 302 to send target data to the main controller 301 at the corresponding target time point.

[0124] For example, consider multiple data acquisition units, namely data acquisition unit A, data acquisition unit B, and data acquisition unit C, with target time points of 1 second, 2 seconds, and 3 seconds, respectively. The main controller 301 sends a first instruction to data acquisition unit A via a serial digital interface, instructing data acquisition unit A to send target data A to the main controller 301 at the corresponding target time point 00:00:01. The main controller 301 sends a first instruction to data acquisition unit B via the serial digital interface, instructing data acquisition unit B to send target data B to the main controller 301 at the corresponding target time point 00:00:02. The main controller 301 sends a first instruction to data acquisition unit C via the serial digital interface, instructing data acquisition unit C to send target data C to the main controller 301 at the corresponding target time point 00:00:03.

[0125] For example, data acquisition unit A receives a first instruction from the main controller 301. Data acquisition unit B receives a first instruction from the main controller 301. Data acquisition unit C receives a first instruction from the main controller 301.

[0126] S803, the data acquisition unit determines the corresponding target time point based on the first instruction.

[0127] For example, data acquisition unit A determines 00:00:01 as the corresponding target time point. Data acquisition unit B determines 00:00:02 as the corresponding target time point. Data acquisition unit C determines 00:00:03 as the corresponding target time point.

[0128] Based on the above technical solution, the main controller determines the target time point corresponding to each data acquisition unit and sends a first instruction to each of the multiple data acquisition units. The data acquisition units receive the first instruction and, based on it, determine their corresponding target time points. Since the first instruction instructs the data acquisition units to send target data to the main controller at the corresponding target time point, in this technical solution, the main controller controls the timing of multiple target data points arriving at the main controller by controlling the time when the data acquisition units send target data to the main controller. This avoids data conflicts or congestion at the main controller, thereby greatly improving the efficiency of the data acquisition system.

[0129] As one possible embodiment of this application, combined with Figure 7 ,like Figure 8 As shown, after S704 above, the main controller can also process the target data through the following S804.

[0130] S804, the main controller processes multiple target data.

[0131] For example, after receiving multiple target data, the main controller unifies the target data into a unified format and outputs a list of target data.

[0132] For example, the main controller compares the differences in the target data and performs calculations for multiple target data.

[0133] Based on the above technical solution, after the main controller acquires multiple target data, the processing of these multiple target data facilitates data analysis by the staff.

[0134] As one possible embodiment of this application, combined with Figure 8 ,like Figure 9 As shown, the process by which the S801 main controller determines the target time point corresponding to each data acquisition unit can also be implemented through the following S901-S903.

[0135] S901. The main controller determines the transmission time interval based on the preset period and the total number of data acquisition units.

[0136] Wherein, the time interval between two adjacent target time points is less than or equal to the ratio of the preset period to the total number of data acquisition units.

[0137] One possible implementation is that the main controller determines the ratio of a preset period to the total number of data acquisition units, and determines that the time interval between multiple data acquisition units sending target data is less than the ratio.

[0138] For example, taking a preset period of 4 seconds and a total number of 3 data acquisition units 302 as an example. The main controller 301 determines that the ratio of the preset period of 4 seconds to the total number of 3 data acquisition units 302 is 4 / 3. The main controller 301 selects any value from the interval [0, 3 / 4], for example, 1. The main controller determines 1 second as the transmission time interval for multiple data acquisition units to send target data.

[0139] S902, the main controller determines the transmission sequence of each data acquisition unit.

[0140] One possible implementation is that the main controller obtains the preset transmission order of multiple data acquisition units.

[0141] Another possible implementation is that the main controller determines the sending priority of the data acquisition unit with the shortest time to acquire the target data based on the time it takes for the data acquisition unit to complete the acquisition of the target data.

[0142] For example, in response to the synchronous data acquisition signal, data acquisition unit A completes the acquisition of target data within 0.01 seconds, data acquisition unit B completes the acquisition of target data within 0.02 seconds, and data acquisition unit C completes the acquisition of target data within 0.03 seconds. Since 0.01 seconds is less than 0.02 seconds, which is less than 0.03 seconds, the main controller determines that data acquisition unit A has the first priority to send target data to the main controller, data acquisition unit B has the second priority to send target data to the main controller, and data acquisition unit C has the third priority to send target data to the main controller.

[0143] S903, the main controller determines the target time point based on the transmission time interval and transmission sequence.

[0144] One possible implementation is that the main controller determines the target time point for each data acquisition unit based on the preset transmission order and transmission time interval of multiple data acquisition units.

[0145] For example, consider multiple data acquisition units, namely data acquisition unit A, data acquisition unit B, and data acquisition unit C, with a preset transmission order of data acquisition unit A, data acquisition unit B, and data acquisition unit C. Since the main controller determines 1 second as the transmission time interval, it determines the target time point for data acquisition unit A as 00:00:01, the target time point for data acquisition unit B as 00:00:02, and the target time point for data acquisition unit C as 00:00:03.

[0146] Based on the above technical solution, the main controller determines the transmission time interval and the transmission order of each data acquisition unit according to the preset period and the total number of data acquisition units, and determines the target time point based on the transmission time interval and transmission order. Since the time interval between two adjacent target time points is less than or equal to the ratio of the preset period to the total number of data acquisition units, this technical solution ensures that the total time for multiple data acquisition units to send target data to the main controller is less than the preset period, avoiding multiple data conflicts or congestion at the main controller, thereby greatly improving the efficiency of the data acquisition system.
