Detailed Implementation

[0018] The technical solutions in 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.

[0019] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] In the following text, the terms "comprising," "having," and their cognates, which may be used in various embodiments of this application, are intended only to indicate a particular feature, number, step, operation, element, component, or combination thereof, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations thereof, or adding the possibility of one or more combinations thereof. Furthermore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0021] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Traditional smart meters with communication capabilities generally refer to PLC carrier (Power Line Communication) systems. Existing automated testing systems for smart meters primarily focus on basic performance tests such as metering errors, lacking testing methods for new IoT communication smart meters. This prevents comprehensive verification of the meter's communication functions and its interactivity with cloud platforms. Traditional wireless communication smart meters only use the communication module (such as a 4G module) as a data transmission channel for the testing system, transmitting test results back without specifically testing key indicators unique to smart meters, such as wireless communication functions and control command response. Traditional multi-communication channel (WIFI / Bluetooth / Infrared) smart meter systems improve reliability through redundant communication, but have limitations. For example, they do not involve automated testing processes before the meter leaves the factory, only verifying channel connectivity and not covering key indicators such as the stability of the smart meter's communication functions and the timeliness of interaction with the cloud platform. Users typically need to manually bind the meter number to their platform account; if the meter is not pre-registered or communication is abnormal, customers will be unable to use it normally.

[0024] To address the aforementioned issues, this application provides an automated factory testing method, system, terminal equipment, and medium for electricity meters. This achieves full automation of the electricity meter testing process, preventing human error in detection. The cloud platform of this application can issue test commands to the corresponding electricity meters, and the terminal equipment obtains the execution records of the electricity meters. This verifies the communication function between the electricity meters and the cloud platform, as well as the interaction and event response capabilities between the electricity meters and the cloud platform, preventing electricity meters with communication malfunctions from reaching the customer. The cloud platform also sends the registration results of each electricity meter to the terminal equipment, which in turn obtains the registration results, further preventing unregistered electricity meters from reaching the customer.

[0025] First, this application provides an automated factory testing system 100 for electricity meters. Please refer to... Figure 1 This is a structural block diagram of an automated factory testing system 100 for electricity meters provided in an embodiment of this application. The automated factory testing system 100 for electricity meters includes a terminal device 110 and a cloud platform 120, wherein the terminal device 110, the cloud platform 120, and multiple electricity meters 130 are directly or indirectly electrically connected to realize data transmission and interaction.

[0026] In this embodiment, the terminal device 110 is used to obtain the unique meter number of each electricity meter 130 and upload it to the cloud platform 120; the cloud platform 120 is used to register each electricity meter 130 upon receiving the unique meter number of each electricity meter 130, and to send the registration status of each electricity meter 130 to the terminal device 110; the terminal device 110 is also used to notify the cloud platform 120 to send a test command to each electricity meter 130 upon receiving the registration status of each electricity meter 130 sent by the cloud platform 120; each electricity meter 130 is used to execute the test command and send the execution record of the test command to the terminal device 110; the terminal device 110 is also used to determine whether each electricity meter 130 is qualified for the test based on the registration status and the execution record. The registration status is used to indicate whether the electricity meter 130 is registered successfully, and the execution record fed back by the electricity meter 130 is used to verify the communication function of the electricity meter 130. This application can perform communication function tests on each electricity meter 130 and obtain the registration status and communication function test results of each electricity meter 130.

[0027] In one embodiment, such as Figure 2 As shown, terminal device 110 and each electricity meter 130 are provided with a communication interface 111. Terminal device 110 communicates with each electricity meter 130 through communication interface 111. This communication interface 111 includes, but is not limited to, RS485 communication interface and RJ45 communication interface. Terminal device 110 includes PC host computer software 112. This PC host computer software 112 uploads the unique meter number of each electricity meter 130 to cloud platform 120 based on Hypertext Transfer Protocol-based Application Programming Interface (HTTP API). Cloud platform 120 sends the registration status of each electricity meter 130. The registration status includes failure status and success status.

[0028] In another embodiment, each electricity meter 130 is equipped with a wireless communication device 131 that communicates with the cloud platform 120 to enable the cloud platform 120 to remotely control, configure, and schedule tasks for multiple electricity meters 130. The wireless communication device 131 includes, but is not limited to, 4G and 5G communication devices, enabling the electricity meters 130 to have remote communication capabilities. This allows them to upload data collected by the electricity meters 130 to the cloud platform 120 in real-time or periodically, and to receive test commands and control commands from the cloud platform 120. Each electricity meter 130 is also equipped with an event recording memory 132, which records the execution record of the electricity meter 130 in response to test commands after the electricity meter 130 executes a corresponding event. The terminal device 110 can read the execution records in the event recording memory 132 of each electricity meter 130 through the communication interface 111.

[0029] For ease of understanding, the following embodiments of this application will be described in terms of... Figure 2 Taking the automated factory testing system 100 for electricity meters shown as an example, and in conjunction with the accompanying drawings, the automated factory testing method for electricity meters 130 provided in this application embodiment will be described.

[0030] Figure 3 A flowchart illustrating an automated factory testing method for an energy meter 130 according to an embodiment of this application is shown. Exemplarily, the automated factory testing method for the energy meter 130 includes the following steps: S210, upload the unique meter number of each electricity meter 130 in the Production Management System (PMS) to the cloud platform 120 so that the cloud platform 120 can register each electricity meter 130 according to each unique meter number.

[0031] In one embodiment, the production management system is a structured data storage system for storing and managing information such as the production, testing, registration, and status of electricity meters 130. Before uploading the unique meter number of each electricity meter 130 in the production management system to the cloud platform 120, the terminal device 110 sends a read meter number command to each electricity meter 130 to obtain and parse the unique meter number of each electricity meter 130.

[0032] In one embodiment, the meter number is written into the internal memory of the energy meter 130 after manufacturing or error verification. When the energy meter 130 that has passed the error verification is powered on, the terminal device 110 sends a read meter number command through the communication interface 111. The read meter number command follows a standard communication protocol, such as DL / T 645-2007 (Communication Protocol for Multifunctional Energy Meter 130). Each energy meter 130 responds to the read meter number command from the terminal device 110 and returns a response frame containing its unique meter number. The terminal device 110 parses the response frame and extracts the meter number information. In this embodiment, an energy meter 130 that has passed the error verification means that the actual error measured by the energy meter 130 under standard test conditions is within the allowable range and meets the requirements of the product metrology specification. Each energy meter 130 has a unique meter number, which enables automatic identification of the energy meter 130, improves verification and deployment efficiency, reduces manual intervention, and lowers the error rate; it supports concurrent identification of multiple meter numbers and is suitable for scenarios where multiple meters are registered in parallel.

[0033] In this embodiment, the cloud platform 120 registers each electricity meter 130 with a unique meter number, establishing a binding between the electricity meter 130's identity and its data. This ensures the self-registration of the electricity meters 130, eliminating the need for users to manually bind the meter number to the cloud platform 120 and preventing users from being unable to use the electricity meters normally due to unregistered meters. The electricity meter 130 data includes, but is not limited to, electricity consumption, meter operating status, and power outage records.

[0034] S220, upon receiving the registration status of each electricity meter 130 sent by the cloud platform 120, notifies the cloud platform 120 to send a test command to each electricity meter 130.

[0035] In this embodiment, the electricity meter 130 receives the test command sent by the cloud platform 120 through the wireless communication device 131 and executes the corresponding events of the test command, such as the circuit breaker event, the circuit breaker closing event, and the electricity meter reset event.

[0036] S230: Obtain the execution record of the test command fed back by each electricity meter 130, so as to determine whether each electricity meter 130 has passed the test based on the registration status and the execution record.

[0037] In one embodiment, the registration status of the electricity meter 130 includes successful registration and failed registration. This application determines that the electricity meter 130 has failed the test and provides feedback to the user regarding the failed registration of the electricity meter 130 when the registration status is "failed registration." A successful registration status indicates that the electricity meter 130 has been successfully registered to the cloud platform 120, and the electricity meter 130's identity is identifiable. In this embodiment, when the terminal device 110 receives a registration failure status, the terminal device 110 indicates the electricity meter 130 with a failed registration status via a pop-up window or an alarm. This application achieves immediate local alarm feedback for electricity meter 130 registration failure events, preventing failed registration electricity meters 130 from entering the user's system, thereby preventing the electricity meter 130 from being unable to be used normally due to not being registered in advance, and improving the maintenance efficiency and anomaly response capability of the electricity meter 130.

[0038] In this embodiment, the execution record includes the execution event type and instruction response time. The electricity meter 130 is used to receive test instructions from the cloud platform 120 through the wireless communication device 131 and execute the event type specified by the test instructions. The event type includes, but is not limited to, power-off events, power-on events, and meter reset events.

[0039] In one embodiment, this application determines that the electricity meter 130 fails the test if the execution record is missing the execution event type and / or instruction response time; if the execution record includes the execution event type and instruction response time, it determines whether the electricity meter 130 passes the test based on the execution event type, instruction response time, and registration status.

[0040] In another embodiment, this application determines that the energy meter 130 fails the test if the type of the executed event is inconsistent with the type of the event specified in the test instruction; if the instruction response time exceeds the preset response time, the energy meter 130 fails the test; and if the type of the executed event is consistent with the type of the event specified in the test instruction, the instruction response time is less than or equal to the preset response time, and the registration status is successful, the energy meter 130 passes the test.

[0041] In this embodiment, the command response time refers to the entire time interval from when the cloud platform 120 issues the test command to when the electricity meter 130 finishes executing the test command. The preset response time can be set according to the actual situation. For example, the test request response timeout time can be set to 60 seconds. When the command response time exceeds 60 seconds, the electricity meter 130 can be recorded as having timed out. The execution event type is consistent with the event type specified in the test command, and the command response time is less than or equal to the preset response time, indicating that the electricity meter 130 has executed the correct test command and executed it within the specified time. This means that the communication function of the wireless communication device 131 in the electricity meter 130 is normal, and it can interact with the cloud platform 120 and respond to the commands of the cloud platform 120. This application can ensure that the qualified electricity meter 130 has the ability to communicate bidirectionally with the cloud platform 120, and ensure that the electricity meter 130 has been registered, reducing the rework rate caused by communication abnormalities after the deployment of the electricity meter 130, and preventing unregistered or malfunctioning electricity meters 130 from entering the user's system.

[0042] In one embodiment, after determining the test results of each electricity meter 130, this application marks each electricity meter 130 in the production management system as qualified and unqualified; and writes the test failure information of the unqualified electricity meter 130 into the production management system; wherein, the test failure information includes one or more of the following: registration failure, missing execution record, test instruction response timeout, and execution event type error.

[0043] In one embodiment, after determining that the electricity meter 130 has passed the test, this application obtains supplementary printing information of the tested electricity meter 130 from the production management system; and sends a printing instruction to the printer to obtain a certificate of conformity for the tested electricity meter 130. The certificate of conformity includes the test result and supplementary printing information. The supplementary information includes, but is not limited to, the production batch number of the electricity meter 130, the testing employee number, etc.
