DETAILED DESCRIPTION

[0011] The embodiment of the present invention solves the technical problem that the current electric meter detection device cannot achieve flexible compatibility of multiple phenotypic detections, resulting in low detection efficiency and low utilization rate of detection equipment, by providing a multi-epitope large-capacity flexible detection device that is compatible with multiple detection objects. It achieves the technical effect of flexibly responding to the detection needs of different meters and improving the calibration work efficiency and equipment working saturation.

[0012] Embodiment 1, as Figure 1 As shown, an embodiment of the present invention provides a multi-epitope large-capacity flexible detection device compatible with a variety of detection objects, the device comprising: The module 10 for determining the type of the inspected object is used to traverse a plurality of inspected tables to be inspected, obtain a target inspected table, and determine the type of the inspected object based on the target inspected table.

[0013] Specifically, the module 10 for determining the type of the object to be inspected traverses all the meters that need to be inspected, selects a specific meter as the target meter to be inspected for specific inspection, and identifies the specific type of the meter, i.e., the type of the object to be inspected, such as a single-phase smart meter or a three-phase inductive smart meter, by reading the characteristic parameters, specifications, or identification tags of the meter. By automatically identifying the type of the meter, a basis for selection and configuration is provided for the subsequent entire inspection process.

[0014] A matching module 20 is used to select a crimping mechanism and a wiring assembly that match the type of the inspected object, wherein the wiring assembly includes a panel tooling, a first connecting wire, a transfer terminal seat and a second connecting wire corresponding to the type of the inspected object.

[0015] Specifically, the matching module 20 automatically selects a suitable crimping mechanism and wiring assembly according to the physical structure and signal requirements of different types of electric meters. Among them, the crimping mechanism is used to firmly connect the wires and the terminals of the electric meter together to ensure the stable transmission of electrical signals. The wiring assembly is a hardware tool that connects the electric meter and the detection equipment to ensure that an effective electrical connection can be made between the electric meter and the calibration device. The wiring assembly includes a panel tool, a first connecting wire, a transfer terminal seat and a second connecting wire. The panel tool is used to fix and support the electric meter under test so that it remains stable during the detection process and facilitates wiring operations. The first connecting wire is used to connect the terminals of the electric meter and the transfer terminal seat to transmit electrical signals. The transfer terminal seat is an intermediate interface used to convert the terminals of the electric meter with the cables of the detection equipment to ensure port compatibility of different types of electric meters. The second connecting wire is a cable from the transfer terminal seat to the detection equipment for transmitting electrical signals.

[0016] The matching module 20 can automatically select the correct hardware tools and devices according to the type of the electric meter, ensuring that the electric meter can be correctly connected to the detection equipment, thereby improving the efficiency and accuracy of the detection process.

[0017] The electrical connection module 30 is used to establish an electrical connection between the target meter under test and the calibration device through the crimping mechanism and the wiring assembly.

[0018] Specifically, the electrical connection module 30 electrically connects the target meter to be inspected with the calibration device through the crimping mechanism and wiring assembly selected by the matching module 20, ensuring that the electrical signal can be stably transmitted between the meter and the detection device. Exemplarily, the meter to be inspected is a three-phase energy meter, and its terminals usually have 6 main ports, corresponding to three electrical phase lines and voltage detection. The electrical connection module 30 will first use the selected crimping mechanism to firmly connect the terminals of the meter to the wires to avoid loose connections or poor contact due to vibration or external force during the test. The wiring assembly transmits signals during the detection process, wherein the first connecting line transmits the signal of the meter terminal to the adapter terminal seat. The adapter terminal seat plays an adaptation role in different types of meters, converting the port format of the meter into a format compatible with the calibration equipment. The second connecting line transmits the signal from the adapter terminal seat to the calibration device. Through these connections, the actual current, voltage and other signals in the meter can be transmitted losslessly to the calibration device for further analysis and calibration.

[0019] The first configuration module 40 is used to identify the actual terminal arrangement information and real-time terminal definition information of the target meter under test, and establish a mapping relationship between the calibration signal of the calibration device and the actual terminals of the target meter under test as the first configuration condition.

[0020] Specifically, the first configuration module 40 determines the first configuration condition by identifying the terminal arrangement and terminal definition information of the meter under test, establishing a signal correspondence between the calibration device and the target meter under test. First, by reading the technical data or built-in information of the meter, the actual terminal specific layout and order of the meter, that is, the actual terminal arrangement information, is identified. For example, for a three-phase inductive smart energy meter, its terminal arrangement may include 6 terminals, which are used to connect three phase lines and a neutral line, as well as the input of the current transformer. The module automatically reads the position arrangement of these terminals and determines the specific order of terminals 1 to 6.

[0021] Through the technical parameters or internal identification of the meter, the functional definition of each terminal is identified, that is, the real-time terminal definition information. The real-time terminal definition information can be used to determine the role of each terminal of the target meter under inspection in different meter types. For example, terminal 1 may be used for phase A voltage input, terminal 2 for phase B voltage input, terminal 3 for current input, etc.

[0022] After determining the actual terminal arrangement information and real-time terminal definition information, the output signal of the calibration device is mapped to the specific terminal of the target meter. For example, the calibration device may need to input a voltage signal to the phase A of the meter. At this time, the module maps the voltage output terminal of the calibration device to the "terminal 1" of the meter, that is, the phase A voltage input terminal. Through this signal and terminal mapping, the detection signal of the calibration device can be accurately transmitted to the corresponding meter port to ensure the accuracy of the test results.

[0023] Through the above terminal arrangement and definition information, the module generates a complete mapping condition for the verification device, namely the first configuration condition, which is used to configure the verification device so that the detection device can transmit signals according to the actual layout of the target meter under test. When detecting different types of meters, the module will automatically update these mapping relationships to ensure that each detection can match the corresponding terminals.

[0024] The second configuration module 50 is used to obtain the output parameters of the power amplifier in the calibration device according to the capacity characteristics of the target meter under test as the second configuration condition.

[0025] Specifically, the second configuration module 50 dynamically adjusts the output parameters of the power amplifier in the calibration device according to the capacity characteristics of the target meter under test, thereby providing an accurate electrical environment for the target meter under test and ensuring that during the detection process, the target meter under test can accept voltage and current within its design range, preventing excessively high or low signals from affecting the detection results.

[0026] The second configuration module 50 first needs to obtain the capacity characteristics of the electric meter from the technical parameters of the electric meter, including the maximum current, maximum voltage or power that the electric meter can withstand. According to the capacity characteristics of the electric meter, the output parameters that the power amplifier needs to provide are calculated, including the specific values ​​of the voltage, current or power output by the power amplifier. The second configuration module 50 uses the calculated output parameters as the second configuration condition to automatically adjust the power amplifier in the calibration device to ensure that the output electrical signal is suitable for the current detection requirements of the electric meter. This second configuration condition ensures that the signal provided by the calibration device meets the design specifications of the target meter being tested, and works together with the first configuration condition to ensure the stable operation of the entire calibration device.

[0027] The verification process determination module 60 is used to select a target verification process template based on the type of the inspected object, and configure the verification items and verification parameters of the target verification process template according to the target inspection table to obtain the target verification process.

[0028] Specifically, the calibration process determination module 60 selects a suitable detection process template according to the type and parameters of the target test sheet, configures the required calibration items and parameters, and finally generates a specific calibration process to ensure that the detection of the target test sheet can be carried out based on its specific needs, avoiding errors caused by general processes.

[0029] The verification process determination module 60 first selects a verification process template that matches the type of the target meter to be tested, i.e., a target verification process template, according to the identified type of the object to be tested. Each template predefines a series of detection steps applicable to the type of meter. For example, if the target meter to be tested is a three-phase meter, a verification template for the three-phase meter is selected, which may include a three-phase voltage and current error test, a phase sequence detection, etc.

[0030] After determining the target calibration process template, the module further configures the calibration items and specific detection parameters (such as voltage and current values) according to the technical parameters of the target meter to be inspected. Different meters require different detection items. Household meters may only need to perform simple current error tests, while industrial meters may also include complex phase calibration. For meters designed to withstand high voltages, the module will set high voltage detection items in the calibration process; for low voltage meters, the module will set corresponding low voltage test parameters. After the above configuration, a complete target calibration process is generated. The process includes all the calibration items and parameters configured for the target meter to be inspected, and guides the calibration equipment to perform detection in a predetermined order.

[0031] Exemplarily, a single-phase smart energy meter is detected, and the type of the object being tested has been identified as "single-phase". The verification process determination module 60 will select the standard verification template for single-phase meters, which includes verification items such as current error test, voltage calibration and functional test. The technical parameters of the meter are obtained. The maximum withstand voltage of the meter is 230V and the maximum current is 10A. The module sets the specific test current to 5A, 10A and the corresponding voltage value. Subsequently, a complete detection process is generated based on the above configuration information to guide the verification device to perform each test step by step and finally generate a verification report.

[0032] The verification result acquisition module 70 is used to set the verification device through the first configuration condition and the second configuration condition, execute the target verification process, complete the verification operation, and generate the target verification result.

[0033] Specifically, the calibration result acquisition module 70 first reads the first configuration condition and the second configuration condition generated previously, determines the connection position of the signal channel of the calibration device according to the first configuration condition, and sets the output of the power amplifier according to the second configuration condition. After the calibration device is set up, the target calibration process is started. The process includes a series of detection tasks, such as error calibration, current response test, phase detection, etc. All operations are performed in sequence to ensure that the detection process is complete and meets the predetermined requirements. During the calibration process, the output of the target meter under test is monitored in real time through sensors and data acquisition modules, and the results of each test item are recorded, including the meter's error, power factor, frequency response and other performance indicators. After the calibration operation is completed, all test data are summarized to generate the target calibration result. This result will clearly show the performance of the target meter under test in each test, including whether it meets the standard, the size of the error, etc.

[0034] The verification result acquisition module 70 ensures that the detection process is carried out strictly in accordance with the set conditions and ultimately provides reliable detection data, thereby determining whether the electric meter meets the expected standards, greatly improving the degree of automation of the detection and the accuracy of the data.

[0035] Furthermore, the multiple inspected meters described in the embodiment of the present invention include a single-phase smart energy meter, a three-phase direct smart energy meter, a three-phase mutual induction smart energy meter, and a collection terminal.

[0036] Specifically, in the embodiment of the present invention, the meter to be tested can be a single-phase smart energy meter, a three-phase direct smart energy meter, a three-phase inductive smart energy meter, and various types of energy meters or acquisition terminals such as acquisition terminals. By using a calibration device compatible with various types of energy meters and acquisition terminals, the automated calibration of diversified detection objects is realized, which is no longer limited to a single phenotype, greatly improving the flexibility of detection, reducing the idle time of the equipment, and optimizing the detection efficiency.

[0037] Further, such as Figure 2 As shown, the first configuration module 40 in the embodiment of the present invention is also used to perform the following steps: A pre-stored terminal information mapping library is obtained, wherein the terminal information mapping library stores terminal arrangement sample information and corresponding terminal definition sample information of multiple historical inspected meters; actual terminal arrangement information of the target inspected meter is collected, and the actual terminal arrangement information is matched with the terminal arrangement sample information in the terminal information mapping library; if the match is successful, the terminal definition sample information corresponding to the matched terminal arrangement sample information is extracted from the terminal information mapping library as the real-time terminal definition information, and a mapping relationship between the verification signal and the actual terminal of the target inspected meter is established; if the match fails, an alarm is issued to the user, instructing the user to check the terminal connection of the target inspected meter and re-establish the mapping relationship.

[0038] Specifically, the terminal information mapping library is a database that stores the terminal arrangement sample information of multiple historically detected electric meters and the corresponding terminal definition sample information. First, call the pre-saved terminal information mapping library. This mapping library contains a large amount of historical electric meter terminal arrangement sample information and corresponding terminal definition information, covering multiple models of electric meters and terminal devices. This provides a reference database for the establishment of the first configuration condition.

[0039] The actual terminal arrangement information of the current meter being tested is collected through sensors or interfaces. This information reflects the physical arrangement and connection order of the terminals on the current meter. The collected actual terminal arrangement information is then compared with the historical samples in the mapping library to find similar arrangement patterns. If matching sample information is found, the match is successful, indicating that the current meter has the same or similar terminal arrangement as a historical meter model in the mapping library. The module will extract the terminal definition sample information corresponding to the matching terminal arrangement sample information from the mapping library as the real-time terminal definition information, and establish a mapping relationship between the verification signal and the actual terminals of the target meter being tested.

[0040] On the contrary, if no sample matching the actual terminal arrangement information is found in the mapping library, the match fails and an alarm is issued to the user, prompting the user to check the connection of the meter terminals or reset the mapping relationship to prevent errors in the detection results due to incorrect or mismatched terminal connections.

[0041] Furthermore, the first configuration module 40 of the embodiment of the present invention is also used to perform the following steps: A terminal scanning device is provided on the calibration device to automatically scan the terminal arrangement of the target meter to be inspected and obtain terminal arrangement image information; image processing is performed on the terminal arrangement image information to extract terminal arrangement feature information, wherein the terminal arrangement feature information includes the number of terminals, terminal spacing, terminal shape and terminal color; and the extracted terminal arrangement feature information is used to generate a terminal arrangement feature vector in a preset format as the actual terminal arrangement information.

[0042] Specifically, the first configuration module 40 collects the actual terminal arrangement information of the target inspected table through the automated image recognition and processing technology of the terminal scanning device. It can automatically identify and generate the actual terminal arrangement information without relying on pre-stored data, thus providing basic support for subsequent inspection operations and greatly improving the efficiency and accuracy of collecting terminal arrangement information.

[0043] A terminal scanning device is provided on the calibration device, which can automatically scan the terminal area of ​​the target meter under inspection and capture the image information of the arrangement of the terminals of the target meter under inspection, i.e., the terminal arrangement image information. The terminal arrangement image shows the specific arrangement, quantity and physical characteristics of the terminals of the target meter under inspection.

[0044] Image processing technology is used to analyze the scanned terminal arrangement image information, and valuable terminal arrangement feature information is extracted from the image, such as the number of terminals, terminal spacing (the distance between terminals), terminal shape (such as whether it is round or square), and terminal color. The terminal features extracted from the image are organized into a terminal arrangement feature vector according to a preset format as the actual terminal arrangement information. This set of terminal arrangement feature vectors is a numerical description of the terminal arrangement, including information such as the number, spacing, shape, and color of the terminals. For example, the terminal arrangement feature vector can be an array containing 6 values, representing the characteristics of the 6 terminals, such as the distance between the terminals (10 mm), shape (round), color (red / black), etc.

[0045] Furthermore, the power amplifier described in the embodiment of the present invention includes a digital power amplifier and a linear power amplifier.

[0046] Specifically, in the calibration device, the power amplifier is used to provide an electric energy signal and simulate different power conditions to detect the accuracy of the electric meter. In an embodiment of the present invention, the power amplifier of the calibration device includes a digital power amplifier and a linear power amplifier. According to the requirements of the target meter to be inspected, a digital power amplifier or a linear power amplifier can be selectively used. Different types of power amplifiers are suitable for different detection scenarios, among which the digital power amplifier amplifies the input signal through digital signal processing. It has efficient energy conversion performance and low energy loss, and is often used in scenarios with high requirements for accuracy and efficiency. The linear power amplifier directly amplifies the input signal and maintains a linear relationship between input and output. Although the energy efficiency is relatively low, its advantage is that it can provide more accurate signal amplification, which is suitable for application scenarios that require precise signals.

[0047] According to the different requirements in the meter detection process, the appropriate power amplifier type is selected to make the calibration device more flexible and adaptable, and can cope with various types of meter detection requirements.

[0048] Further, such as Figure 3 As shown, the device described in the embodiment of the present invention is also used to perform the following steps: A first threshold and a second threshold for the number of meters under test are set, wherein the first threshold is greater than the second threshold, and a third threshold and a fourth threshold for the output stability requirement are set, wherein the third threshold is greater than the fourth threshold; when the number of multiple meters under test is greater than or equal to the first threshold, or the output stability requirement for the power amplifier is less than or equal to the fourth threshold, the digital power amplifier is selected as the power amplifier; when the number of multiple meters under test is less than or equal to the second threshold, or the output stability requirement for the power amplifier is greater than or equal to the third threshold, the linear power amplifier is selected as the power amplifier.

[0049] Specifically, the power amplifier selection criteria are quantified by setting thresholds related to the number of meters under test and output stability, and the power amplifier is automatically adjusted to optimize the efficiency and accuracy of the detection process.

[0050] First, two thresholds for the number of meters under test, namely the first threshold and the second threshold, are set, wherein the first threshold is greater than the second threshold, and two thresholds for the output stability of the power amplifier, namely the third threshold and the fourth threshold, wherein the third threshold is greater than the fourth threshold. For example, the first threshold can be set to 100 meters under test, and the second threshold can be set to 10 meters under test; the third threshold and the fourth threshold may be defined according to the fluctuation rate of the output power or the frequency accuracy.

[0051] When the number of meters under test is greater than or equal to the first threshold, or the stability requirement of the power amplifier output of the test task is less than or equal to the fourth threshold, the digital power amplifier is automatically selected. The high efficiency and adaptability of the digital power amplifier make it very suitable for the test task of large quantities of electric meters, especially when the accuracy requirement is not high.

[0052] When the number of meters under test is less than or equal to the second threshold, or the stability requirement of the power amplifier output by the test task is greater than or equal to the third threshold, the linear power amplifier is automatically selected. The linear power amplifier provides higher signal accuracy and stability, and is suitable for small batches of high-precision test tasks.

[0053] For example, on a large production line, 200 single-phase energy meters need to be calibrated simultaneously. Since the number exceeds the first threshold and the accuracy requirement is low, digital power amplifiers are preferred to improve overall efficiency. When only five high-precision three-phase inductive energy meters need to be tested and the fluctuation of the output signal needs to be controlled within an extremely low range, linear power amplifiers are selected to ensure the accuracy of the detection.

[0054] By setting the above thresholds, the detection device can dynamically switch the power amplifier according to the number of meters to be tested and the detection accuracy requirements, so as to flexibly respond to different production and detection needs, while ensuring accuracy and maximizing work efficiency.

[0055] Furthermore, the apparatus described in the embodiment of the present invention is also used to perform the following steps: When the power amplifier is a digital power amplifier, the voltage and current vector diagram data of the target meter under test is obtained, a digital signal is generated according to the voltage and current vector diagram data, the digital signal is converted into an analog signal through a digital-to-analog converter and amplified as the output of the digital power amplifier; the standard power value is calculated according to the voltage amplitude, current amplitude and power factor of the digital signal; the output voltage and output current of the digital power amplifier are collected in real time, the output power is calculated, and the output power is compared with the standard power value; if the output power is less than the standard power value, the power supply voltage of the digital power amplifier is increased until the output power reaches the standard power value; if the output power is greater than the standard power value, the power supply voltage of the digital power amplifier is reduced until the output power reaches the standard power value.

[0056] Specifically, when a digital power amplifier is selected based on the aforementioned threshold judgment conditions, the output power of the digital power amplifier is ensured to be stable at a standard value through data input and digital-to-analog conversion of the voltage and current vector diagram, combined with a dynamic power adjustment mechanism, thereby improving the accuracy and efficiency of the meter detection.

[0057] First, the voltage and current vector diagram data of the target meter under test are obtained through the calibration device. These vector diagrams contain information such as the amplitude and phase of the voltage and current, indicating the power transmission characteristics of the target meter under test. Corresponding digital signals are generated based on these vector diagram data. The digital signals are converted into corresponding analog voltage and current signals through a digital-to-analog converter (DAC). The converted analog signals are further amplified as the output signals of the digital power amplifier.

[0058] The ideal standard power value is calculated based on the voltage amplitude, current amplitude and power factor of the generated digital signal as the target value of the output power. For example, when the voltage is 220V, the current is 10A, and the power factor is 0.95, the standard power value is calculated as 220V×10A×0.95=2090W. Next, the output voltage and current of the digital power amplifier are collected in real time, the actual output power is calculated, and compared with the standard power value calculated previously. If the output power is less than the standard power value, the output power is gradually increased by increasing the power supply voltage of the digital power amplifier; if the output power is greater than the standard power value, the power supply voltage is reduced and the output power is reduced until the output power is equal to the standard power value.

[0059] Furthermore, the apparatus described in the embodiment of the present invention is also used to perform the following steps: When the power amplifier is a linear power amplifier, the capacity characteristic parameters of the target meter under test are obtained; the optimal working state of the linear power amplifier is determined according to the capacity characteristic parameters, including the optimal load range and the optimal tube voltage drop range; the output load and tube voltage drop of the linear power amplifier are monitored in real time to determine whether the current working state meets the optimal working state; if the output load exceeds the optimal load range, the current booster gear of the linear power amplifier is adjusted to change the input voltage so that the output load falls back to the optimal load range; if the current tube voltage drop deviates from the optimal tube voltage drop range, the gate bias voltage is dynamically adjusted to return the tube voltage drop to the optimal tube voltage drop range.

[0060] Specifically, when a linear power amplifier is selected according to the aforementioned threshold judgment condition, the linear power amplifier is monitored and adjusted in real time to ensure that it operates under optimal load and tube voltage drop conditions, thereby ensuring the accuracy of the detection result and the stability of the amplifier.

[0061] First, obtain the capacity characteristic parameters of the target device under test. These parameters include the maximum operating load, capacitance value, voltage and other characteristics of the target device, which determine the power range required during the detection process. Based on these capacity characteristic parameters, calculate the optimal operating conditions of the linear power amplifier, including the optimal load range (such as current or voltage) and the optimal tube voltage drop range. Among them, the optimal load range refers to the current or voltage range in which the linear power amplifier can operate efficiently and stably under specific load conditions. Exceeding this range may cause the performance of the linear power amplifier to degrade or the efficiency to become lower. The tube voltage drop refers to the voltage drop across the power transistor inside the amplifier. The optimal tube voltage drop range is the voltage range maintained by the power transistor during normal operation. Deviating from this range may cause power loss or equipment overheating.

[0062] During the detection process, the output load and tube voltage drop of the linear power amplifier are monitored in real time to determine whether the output load is within the optimal load range and whether the tube voltage drop is within the optimal tube voltage drop range. If so, it means that the linear power amplifier meets the optimal working state. Otherwise, it does not meet the requirements and the linear power amplifier needs to be adjusted.

[0063] When the output load of the linear power amplifier is detected to be beyond the optimal load range, the booster gear is automatically adjusted to bring the output load back to the preset optimal range. The booster is an adjustment element inside the linear power amplifier, which is used to adjust the input voltage. By changing the booster gear, the input voltage of the linear power amplifier can be adjusted, thereby changing the output load.

[0064] When the tube voltage drop of the linear power amplifier is detected to exceed the optimal tube voltage drop range, the gate bias voltage is dynamically adjusted to return the tube voltage drop to the normal range. The gate bias voltage is used to control the working state of the internal transistor of the linear power amplifier. By dynamically adjusting the gate bias voltage, the tube voltage drop of the linear power amplifier can be changed.

[0065] For example, a linear power amplifier is used to detect a three-phase energy meter with a maximum load of 50A, an operating voltage of 480V, and an optimal tube voltage drop range of 0.7V to 1.5V. During the detection process, if the output current of the amplifier is monitored to exceed 50A, the current booster gear of the linear power amplifier will be automatically adjusted down to reduce the input voltage and return the output load to the optimal range. If the tube voltage drop is detected to be high (exceeding 1.5V), the gate bias voltage will be automatically reduced to bring the tube voltage drop back to a safe range, thereby ensuring the normal operation of the linear power amplifier.

[0066] By real-time monitoring and automatic adjustment of the output load and tube voltage drop of the linear power amplifier, it is ensured that the linear power amplifier always operates in the best working state, avoiding overload or power loss problems. This not only improves the detection accuracy, but also extends the service life of the equipment. It is suitable for meter detection scenarios that require high precision and high stability.

[0067] In summary, the multi-epitope large-capacity flexible detection device compatible with multiple detection objects provided by the embodiment of the present invention has the following technical effects: The module 10 for determining the type of the object to be inspected traverses multiple inspected tables to be inspected, obtains the target inspected table, and automatically identifies the type of the inspected object based on the target inspected table, providing a basis for subsequent matching of correct detection procedures and parameters. The matching module 20 selects a crimping mechanism and a wiring assembly that match the type of the inspected object, wherein the wiring assembly includes a panel tooling, a first connecting line, a transfer terminal seat, and a second connecting line corresponding to the type of the inspected object. Through a flexible matching mechanism, the connection of different types of electric meters is achieved, the compatibility and efficiency of the detection are ensured, and the frequency of equipment replacement is reduced. The electrical connection module 30 establishes an electrical connection between the target inspected table and the calibration device through the crimping mechanism and the wiring assembly, providing a stable electrical signal for subsequent calibration operations, and reducing the detection error caused by poor connection. The first configuration module 40 identifies the actual terminal arrangement information of the target inspected table, calls the terminal information mapping library to automatically obtain the matching real-time terminal definition information, and establishes a mapping relationship between the calibration signal of the calibration device and the actual terminal of the target inspected table as the first configuration condition, ensuring the accurate transmission of the detection signal and improving the accuracy of the connection. The second configuration module 50 automatically adjusts the output parameters of the power amplifier in the calibration device according to the capacity characteristics of the target meter to be tested as the second configuration condition, thereby realizing adaptive adjustment of the detection conditions so that it can adapt to the capacity requirements of different meters and improve the flexibility and adaptability of detection. The calibration process determination module 60 selects a target calibration process template based on the type of the object to be tested, and configures the calibration items and calibration parameters of the target calibration process template according to the characteristics of the target meter to obtain a personalized target calibration process. The calibration result acquisition module 70 sets the calibration device through the first configuration condition and the second configuration condition, executes the target calibration process, completes the calibration operation, and generates a target calibration result.

[0068] In general, the embodiment of the present invention realizes flexible and compatible detection of various types of electric meters by integrating the above-mentioned modules. It can automatically identify the type of electric meter to be tested, flexibly select the wiring assembly that matches it, ensure stable electrical connection, and automatically adjust the detection parameters according to the actual terminal arrangement and capacity characteristics, which significantly improves the flexibility and adaptability of the calibration device. In addition, by personalizing the configuration of the calibration process, manual intervention and operational errors are reduced, and the detection efficiency and accuracy are improved. While meeting the actual production needs, the device achieves an improvement in the working saturation of the equipment, that is, when faced with the detection tasks of different types of measuring instruments, it can more efficiently dispatch and utilize resources, avoiding idleness and inefficiency caused by the specificity of the equipment.
