Description

Technical Field

[0001] This invention belongs to the field of power metering technology, specifically relating to a method and acquisition terminal for reading minute-level frozen data from an electricity meter. Background Technology

[0002] With the continuous deepening of smart grid construction and the upgrading of electricity information collection systems, the electricity marketing business has put forward higher requirements for the granularity of user electricity data collection: the traditional collection mode mainly focuses on the user's total daily electricity consumption, while in order to achieve more refined load analysis and grid management, the current collection mode has begun to fully promote the collection of minute-level frozen data, such as one data point every 15 minutes, for a total of 96 points throughout the day. This has increased the amount of data that a single electricity meter needs to collect and upload by orders of magnitude compared to the past.

[0003] In existing low-voltage centralized meter reading field operation and maintenance scenarios, the operation mode of mobile terminal + data acquisition terminal is usually adopted. In this mode, the data acquisition terminal can use additional devices such as back clips. In this mode, the data acquisition terminal only plays the role of communication relay device for transparent transmission. All business logic, protocol parsing, encryption and decryption operations are dominated by the APP on the mobile terminal.

[0004] For the re-reading of frozen data at the minute level, due to the large amount of data, it is usually necessary to read the data in multiple data frames. Under the existing interaction architecture, each time the mobile terminal initiates a read command, it needs to go through the link of "mobile terminal -> Bluetooth -> data acquisition terminal -> infrared -> electricity meter". After the electricity meter replies, the data is returned to the mobile terminal for parsing and verification before the next frame command can be initiated. This interaction mechanism results in dozens of data round trips between the mobile terminal and the data acquisition terminal.

[0005] However, the field operation environment is often complex, and near-field communication such as Bluetooth or WiFi is easily interfered with. Frequent handshakes and data interactions not only lead to unstable communication links and are prone to failures such as mid-way disconnection and timeout, but also significantly increase the overall time consumption of data collection, resulting in low on-site operation and maintenance efficiency and making it difficult to meet the batch collection needs of massive amounts of minute-level data.

[0006] Therefore, there is an urgent need for a method to read minute-level frozen data from electricity meters that can optimize the interaction process and improve data reading efficiency and stability. Summary of the Invention

[0007] One of the objectives of this invention is to at least solve one or more of the aforementioned problems existing in the prior art. In other words, one of the objectives of this invention is to provide a method and acquisition terminal for reading minute-level frozen data of an electricity meter that meets one or more of the aforementioned requirements.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for reading minute-level frozen data from an electricity meter, comprising: The data acquisition terminal can acquire structured data containing multiple meter reading task instructions and key information from the mobile terminal at once; The data acquisition terminal parses structured data to extract meter reading task instructions and key information for interacting with the target electricity meter; Based on the meter reading task instructions and key information, the data acquisition terminal establishes a connection with the designated electricity meter and completes identity authentication; after successful identity authentication, it collects multiple frames of minute-level frozen data from the designated electricity meter. The acquisition terminal integrates all multi-frame minute-level frozen data into back-transmitted data; The data acquisition terminal will send the returned data to the mobile terminal.

[0009] As a preferred implementation, the acquisition terminal integrates all multi-frame minute-level frozen data into return data, including: The data acquisition terminal compresses the transmitted data.

[0010] In a preferred embodiment, the method further includes the acquisition terminal obtaining the data format returned from the mobile terminal; The acquisition terminal integrates all multi-frame minute-level frozen data into backhaul data, including: The acquisition terminal performs format verification and splicing on all multi-frame minute-level frozen data according to the returned data format.

[0011] In one preferred implementation, the data acquisition terminal establishes a connection with the designated electricity meter and completes identity authentication, including: The data acquisition terminal calls the local security module to generate authentication ciphertext based on the key information, and sends the authentication ciphertext to the designated electricity meter through the infrared communication module to complete the authentication of the designated electricity meter.

[0012] As a preferred implementation, the structured data is in JSON format.

[0013] On the other hand, the present invention also provides a method for reading minute-level frozen data from an electricity meter, comprising: The mobile terminal obtains multiple meter reading task instructions and the corresponding key information of the electricity meter; The mobile terminal generates structured data containing multiple meter reading task instructions and key information; The mobile terminal sends structured data to the data acquisition terminal at once, triggering the data acquisition terminal to establish a connection with the designated electricity meter and acquire multiple frames of minute-level frozen data according to the meter reading task instructions; The mobile terminal obtains back data containing multiple frames of minute-level frozen data from the acquisition terminal; The mobile terminal will send the returned data to the main station.

[0014] In a preferred embodiment, the mobile terminal obtains feedback data containing multiple frames of minute-level frozen data from the acquisition terminal, including: The mobile terminal decompresses the transmitted data.

[0015] As a preferred implementation, the structured data is in JSON format.

[0016] In one preferred implementation, the mobile terminal acquires the data return format and sends the data return format to the acquisition terminal.

[0017] On the other hand, the present invention also provides a data acquisition terminal, comprising: The Bluetooth module is used for data interaction with the mobile terminal; Infrared communication module, used for data interaction with the electricity meter; The security module is used to generate authentication ciphertext based on key information; Memory and processor; The processor is connected to the Bluetooth module, infrared communication module, and security module respectively, and is configured to perform the following operations: The control Bluetooth module can acquire structured data containing multiple meter reading task instructions and key information from the mobile terminal at once; Parse structured data to extract meter reading task instructions and key information for interacting with the target electricity meter; The control security module establishes a connection with the designated electricity meter and completes identity authentication based on the meter reading task command and key information; after the identity authentication is successful, the control infrared communication module collects multiple frames of minute-level frozen data from the designated electricity meter. All multi-frame minute-level frozen data are integrated into the return data; The Bluetooth module is controlled to send the returned data to the mobile terminal.

[0018] Compared with existing technologies, the method and acquisition terminal for reading minute-level frozen data from an electricity meter provided by this invention have the following advantages: This invention changes the interaction mode between the mobile terminal and the data acquisition terminal. The mobile terminal sends structured data containing meter reading task instructions and key information in a single transmission, triggering the data acquisition terminal to independently execute subsequent operations. This eliminates the frequent wireless interactions between the mobile terminal and the data acquisition terminal during the reading of multiple data frames, reducing what could have been dozens of handshake communications to a single transmission and return. This not only significantly reduces handshake time but also avoids process interruptions caused by interference in intermediate links, significantly improving the overall speed and stability of minute-level frozen data acquisition.

[0019] Furthermore, the acquisition terminal integrates and splices the collected multi-frame minute-level frozen data locally, and compresses it to generate the return data. By utilizing the computing power of the acquisition terminal, redundant communication protocol frame headers / tails are removed before data return, and the data volume is reduced through compression algorithms, thus solving the problem of slow transmission of massive minute-level data on low-bandwidth wireless links.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of the invention. Various processes or components may be appropriately omitted, substituted, or added to the various examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0023] Before introducing the invention, for ease of understanding, the existing methods for reading electricity meter data will be explained first: Currently, the existing on-site copying system mainly consists of hardware devices (mobile phone and dedicated mobile phone back clip) and software (mobile phone application APP, back clip embedded program).

[0024] In the standard on-site meter interaction process, such as Figure 1 As shown, the mobile app obtains meter reading information from the main station systems such as the data acquisition system and the secure management system, and then the mobile app initiates the business and controls the data flow. However, when performing minute-level data supplementation, due to the large amount of data returned by the electricity meter, using the original communication processing mechanism would result in multiple data interactions between the mobile app and the battery clip. Taking the infrared authentication step involved in each communication as an example, there were 8 data interactions between the mobile phone and the battery clip. The detailed process is as follows... Figure 2 As shown, it includes: The phone sends a command to request a random number to the security unit in the back clip; The safety unit in the back clip responds to the command and returns a random number; The mobile phone sends a random number to the back clip via infrared, and then the back clip forwards it to the electricity meter. The electricity meter responds to the random number and returns the serial number and random number to the back clip; The back clip sends the serial number and random number back to the phone; The phone sends a random number processing command to the security unit in the back clip; The safety unit in the back clip responds to the command and returns a random number; The mobile phone sends a random number to the back clip via infrared, and then the back clip forwards it to the electricity meter. The electricity meter responds with a random number, authentication is successful, and minute-level frozen data is sent to the back clip; The back clip forwards minute-level frozen data to the phone, completing one transmission.

[0025] As can be seen, the above process requires repeated communication between the mobile phone and the phone clip every time data is retrieved from the electricity meter. In actual minute-level data readings, each subsequent frame of data reading requires repeating this back-and-forth communication. This not only results in high communication overhead and low efficiency, but also directly leads to long waiting times and increased workload for on-site operators.

[0026] An embodiment of the present invention provides a method for reading minute-level frozen data from an electricity meter. Please refer to [link / reference]. Figure 3 This is a flowchart illustrating a method for reading minute-level frozen data from an electricity meter according to an embodiment of the present invention. The method is applied to a mobile terminal and includes the following steps S100-S104.

[0027] S100: The mobile terminal obtains multiple meter reading task instructions and the key information of the corresponding electricity meters.

[0028] Specifically, the mobile terminal connects to the main data acquisition station and the secure data management system to download the current work order. This work order contains the asset number, key information, and time period for which data needs to be read or re-read.

[0029] The mobile terminal can be connected to the main station system via 4G / 5G / LTE networks, which is convenient for on-site use.

[0030] S101, the mobile terminal generates structured data containing multiple meter reading task instructions and key information.

[0031] Specifically, the mobile terminal generates structured data that conforms to a preset protocol locally based on the downloaded job task order. This structured data includes the asset number of the target electricity meter, key information for identity authentication, and the time period of the frozen data to be read.

[0032] Optionally, the structured data is in JSON format. JSON format is lightweight, easy to parse, and cross-platform. The specific content of the structured data is encapsulated in this JSON data packet.

[0033] Further optionally, in some embodiments of the method, step S100 further includes S1001, whereby the mobile terminal obtains the return data format from the main station system and sends the return data format to the acquisition terminal. In this way, the acquisition terminal will preprocess the data according to this format and return structured data that conforms to the format. The mobile terminal can directly obtain data that meets the requirements of the main station system without performing additional processing locally, further reducing the data processing burden on the mobile terminal.

[0034] S102, the mobile terminal sends the structured data to the acquisition terminal at once to trigger the acquisition terminal to establish a connection with the designated electricity meter and collect multiple frames of minute-level frozen data according to the meter reading task instruction.

[0035] At this time, the mobile terminal will send the meter reading task instructions and corresponding key information of multiple electricity meters to the back clip at once. It does not need to send the information required for the single step instruction to the back clip every time it obtains data from the electricity meter. Moreover, the interaction result can be obtained immediately after the interaction.

[0036] S103, the mobile terminal obtains the return data containing multiple frames of minute-level frozen data from the acquisition terminal.

[0037] After the structured data is sent to the acquisition terminal at once, triggering the acquisition terminal to establish a connection with the designated electricity meter according to the meter reading task instruction and collect multiple frames of minute-level frozen data, the mobile terminal waits for the acquisition terminal to complete all meter reading task instructions, and then receives the feedback result sent by the acquisition terminal at once, which contains multiple electricity meters and multiple frames of minute-level frozen data.

[0038] Optionally, if the data acquisition terminal has compression enabled, the mobile terminal will also decompress the transmitted data and use the corresponding decompression algorithm to restore the original data after receiving the data.

[0039] S104, the mobile terminal sends the return data to the main station.

[0040] After receiving the feedback results from the data acquisition terminal, which contain multiple electricity meters and multiple frames of minute-level frozen data, the mobile terminal sends the feedback results to the main station through the 4G / 5G / LTE network connection between the mobile terminal and the main station, thus completing the on-site data acquisition work.

[0041] The method of this invention enables the mobile terminal to send structured data containing meter reading task instructions and key information in a single transmission, triggering the acquisition terminal to independently execute subsequent operations. This eliminates the frequent wireless interactions between the mobile terminal and the acquisition terminal during the reading of multiple frames of data, reducing what could have been dozens of handshake communications to a single transmission and a single return transmission. This not only significantly reduces handshake time but also avoids process interruptions caused by interference in intermediate links, significantly improving the overall speed and stability of minute-level frozen data acquisition.

[0042] Embodiments of the present invention also provide a method for reading minute-level frozen data from an electricity meter; please refer to [link / reference]. Figure 4 This is a flowchart illustrating a method for reading minute-level frozen data from an electricity meter according to an embodiment of the present invention. The method is applied to the data acquisition terminal side and includes the following steps S200-S204.

[0043] S200: The data acquisition terminal acquires structured data containing multiple meter reading task instructions and key information from the mobile terminal in one go.

[0044] Specifically, the structured data includes the target electricity meter's asset number, key information used for authentication, and the time period for which the frozen data needs to be read.

[0045] Optionally, the data acquisition terminal can establish a data connection with the mobile terminal via a wireless connection, such as a Bluetooth module, or a wired connection, such as a USB interface.

[0046] Optionally, the structured data is in JSON format. JSON format is lightweight, easy to parse, and cross-platform. The specific content of the structured data is encapsulated in this JSON data packet.

[0047] Further optionally, in some embodiments of the method, step S200 further includes S2001, whereby the acquisition terminal receives the data return format specified by the main station system from the mobile terminal, performs data preprocessing according to this format in subsequent processes, and returns structured data that conforms to the format.

[0048] The returned data format can be included in the header or configuration fields of the above structured data. This format defines the data organization form that the mobile terminal expects to receive, such as whether to retain the frame header, whether to use hexadecimal transcoding, check digit rules, etc. The acquisition terminal will cache this format requirement locally to guide the subsequent data integration process.

[0049] In these embodiments, the mobile terminal can directly obtain data that meets the requirements of the main station system without performing additional local processing, further reducing the data processing burden on the mobile terminal. S201, the acquisition terminal parses structured data to extract meter reading task instructions and key information for interacting with the target electricity meter.

[0050] Specifically, after the processor inside the acquisition terminal receives the JSON data packet, it performs deserialization processing, breaking down the long message into specific execution parameters.

[0051] S202, the data acquisition terminal establishes a connection with the designated electricity meter and completes identity authentication based on the meter reading task instruction and key information.

[0052] In a specific embodiment, the identity authentication process involves hardware collaboration.

[0053] Figure 5 This is a flowchart illustrating how the data acquisition terminal establishes a connection with the designated electricity meter and completes identity authentication, such as... Figure 5 As shown, the data acquisition terminal calls its local security module, such as the ESAM module, to generate authentication ciphertext based on the key information. Subsequently, it sends the ciphertext to the designated electricity meter via an infrared communication module. The electricity meter verifies the ciphertext, and authentication is completed upon successful verification. It should be noted that this process is entirely completed locally by the data acquisition terminal in a closed loop, eliminating the need to send random numbers back to the mobile phone for calculation, as is required in existing technologies. Through this mechanism, the random numbers and ciphertext that previously required back-and-forth transmission between the mobile terminal and the electricity meter now only need to communicate between the data acquisition terminal and the electricity meter, completely eliminating the latency and security risks associated with frequent Bluetooth transmissions to the mobile terminal.

[0054] More specifically, during this period, the data acquisition terminal independently handles possible communication timeouts or handshake failures. If the handshake fails, a retry mechanism is automatically triggered without reporting an error to the mobile terminal, until the preset maximum number of retry attempts is reached.

[0055] S203, after successful identity authentication, collects multiple frames of minute-level frozen data from the designated electricity meter.

[0056] After successful authentication, the data acquisition terminal gains data reading permission. Given the large volume of frozen data (often frozen every minute), the electricity meter typically cannot return all data in a single frame. In this embodiment, the acquisition terminal automatically constructs multiple read commands based on the parsed task instructions, continuously sends requests to the electricity meter, and receives multiple frames of data streams returned by the meter. During this process, the acquisition terminal temporarily stores each frame of raw data received in its local buffer.

[0057] S204, the acquisition terminal integrates all multi-frame minute-level frozen data into backhaul data and sends the backhaul data to the mobile terminal.

[0058] In this embodiment of the invention, in order to further improve the processing efficiency of the mobile terminal for aggregated data, the acquisition terminal performs format verification and splicing of the data locally, and then sends the feedback result containing multiple electricity meters and multiple frames of minute-level frozen data to the mobile terminal at once.

[0059] Specifically, the acquisition terminal can perform format verification and splicing on all multi-frame minute-level frozen data according to the pre-acquired return data format, remove redundant communication frame headers and tails, and retain the valid data payload.

[0060] Alternatively, before transmitting the data back, the acquisition terminal can compress the transmitted data, for example, using compression algorithms such as GZIP or ZIP, to compress the concatenated data into a smaller compressed package before sending it to the mobile terminal. This method can significantly reduce the data transmission time between the acquisition terminal and the mobile terminal, improving the user experience.

[0061] The method of this invention enables the data acquisition terminal to receive structured data containing meter reading task instructions and key information from the mobile terminal in a single transaction, and then independently execute subsequent operations. This eliminates the frequent wireless interactions between the mobile terminal and the data acquisition terminal during the reading of multiple frames of data, reducing what could have been dozens of handshake communications to a single transmission and a single return. This not only significantly reduces handshake time but also avoids process interruptions caused by interference in intermediate links, significantly improving the overall speed and stability of minute-level frozen data acquisition.

[0062] Please see Figure 6 The figure shows a schematic diagram of a data acquisition terminal provided in an embodiment of the present invention. As shown, the data acquisition terminal is a back clip and includes: a Bluetooth module 101, an infrared communication module 102, a security module 103, a memory 104, and a processor 105.

[0063] Bluetooth module 101 is used to establish a communication connection with the mobile terminal to receive and send data. It should be noted that Bluetooth is only one optional communication method; in practical applications, a USB interface or a Wi-Fi module can also be used.

[0064] The infrared communication module 102 is used to establish a communication link with the electricity meter and perform data transmission and reception at the physical layer.

[0065] Security module 103 is used to store keys and perform encryption operations. In a specific embodiment, this module can be a standard-compliant ESAM module to ensure the security of data interaction.

[0066] The processor 105 is connected to the Bluetooth module 101, the infrared communication module 102, the security module 103, and the memory 104, respectively. The processor 105 is configured to execute the steps of methods S100-S104 in the above embodiments.

[0067] Specifically, the processor 105 controls the Bluetooth module 101 to receive structured data from the mobile terminal in one go and cache it in the memory 104; the processor 105 parses the data and extracts the instructions and keys; the processor 105 schedules the security module 103 to generate authentication ciphertext and completes the authentication of the electricity meter through the infrared communication module 102; after successful authentication, the processor 105 controls the infrared communication module 102 to read minute-level frozen data in batches and integrates and compresses the data in the memory 104; finally, the results are transmitted back through the Bluetooth module 101.
