[0044] The central coordinator 201 (CCO) is a core control unit in the entire power system, responsible for coordinating and managing the communication and data exchange between multiple devices or nodes.

[0045] The energy meter 202 may be a smart meter installed at the user end, which can monitor power data in real time, such as voltage, current, power factor, etc., and collect information such as switch status and transformer temperature.

[0046] The power system 200 also includes a communication unit 210 under test, which can be at least one of a communication unit of the central concentrator 201 and a communication unit (Station, STA) of the electric energy meter. The STA can be a single-phase STA or a three-phase STA. A one-way STA refers to a station module for single-phase electric energy metering. A three-phase STA refers to a station module for three-phase electric energy metering.

[0047] That is, the test system 100 can test at least one of the communication unit of the central concentrator 201 and the communication unit of the electric energy meter.

[0052] The function limitation method involved in this application can be implemented based on cloud technology, that is, the host computer is a cloud server.

[0053] Among them, cloud technology refers to a hosting technology that unifies hardware, software, network and other resources within a wide area network or local area network to achieve data calculation, storage, processing and sharing.

It can form a resource pool, which can be used on demand and is flexible and convenient. Cloud computing technology will become an important support. The backend services of the technical network system require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the rapid development and application of the Internet industry, in the future, each item may have its own identification mark, which needs to be transmitted to the backend system for logical processing. Data of different levels will be processed separately. All kinds of industry data need strong system backing support, which can only be achieved through cloud computing.

[0055] The function restriction method of the present application can be implemented based on cloud computing. Cloud computing is a computing model that distributes computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power, storage space and information services as needed. The network that provides resources is called a "cloud". The resources in the "cloud" are infinitely expandable in the eyes of users, and can be obtained at any time, used on demand, expanded at any time, and paid for by use.

[0056] As a provider of basic cloud computing capabilities, a cloud computing resource pool (referred to as a cloud platform, generally referred to as an IaaS (Infrastructure as a Service) platform) will be established, and various types of virtual resources will be deployed in the resource pool for external customers to choose to use. The cloud computing resource pool mainly includes: computing devices (virtualized machines, including operating systems), storage devices, and network devices.

[0144] The test device 20 is connected to the host computer 10 in communication. The host computer 10 can issue test instructions to the test device 20 by running test cases. The test device 20 is a hardware device for specific test control. The test device 20 is respectively connected to the communication unit under test, the listening device 30 and the accompanying test device 40 to realize the control and communication of the communication unit under test, the listening device 30 and the accompanying test device 40. The test device 20 can obtain communication data directly with the communication unit under test and the accompanying test device 40.

[0145] The monitoring device 30 is used to monitor the communication data between the communication unit under test 210 and the accompanying device under test 40 .

[0146] It can be understood that the various functions of the communication unit under test 210 generally cannot be implemented independently and can only be used in the constructed power system environment. Therefore, after the power system environment is constructed, the functions of the communication unit under test 210 can be guaranteed to be realized by controlling the communication unit under test 210 and the accompanying test device 40 to perform corresponding test operations, thereby realizing the functional test of the communication unit under test 210.

[0147] The accompanying test device 40 may be one of the communication units of the central concentrator 201 and the electric energy meter 202 , and the accompanying test device 40 may be the other of the communication unit of the central concentrator 201 and the communication unit of the electric energy meter 202 .

[0149] It should be noted that Figure 1 The number of central concentrators 201 and electric energy meters 202 is only used as an example, and the number of central concentrators 201 and electric energy meters 202 can also be more or less, which is not limited here. The central concentrator 201 and the electric energy meter can be directly or indirectly connected through wired (such as power lines) or wireless communication, which is not limited in this application.

[0150] Based on the introduction of the above-mentioned related scenarios, the embodiment of the present application provides a test method for a communication unit of an electric power system. The test method is described in detail below:

[0151] See also Figure 3 A testing method provided in an embodiment of the present application is implemented by steps 011 to 013, which are described in detail below.

[0152] Step 011: Generate a simulated concentrator and a simulated electric energy meter to construct a simulated power consumption system. The simulated power consumption system includes a simulated concentrator, a simulated electric energy meter, an actual concentrator, and a communication unit of the actual electric energy meter. The simulated concentrator communicates with the communication unit of the actual concentrator, and the simulated electric energy meter is used to generate simulated power consumption data and communicate with the communication unit of the actual electric energy meter.

[0153] The simulated concentrator is a software object that runs in the test software of the host computer and realizes the communication and control of the actual concentrator (i.e., the CCO in the application scenario). The simulated energy meter is a software object that runs in the test software of the host computer and realizes the communication and control of the actual energy meter (i.e., the STA in the application scenario).

[0154] Specifically, see Figure 4 In actual test scenarios, since the actual electric energy meter is generally disconnected from the power grid and the power consumption data collected by the actual electric energy meter is uncontrollable, the power consumption data generated by the actual electric energy meter is generally not used. Therefore, the present application generates a simulated electric energy meter to generate controllable simulated power consumption data, thereby facilitating the testing of the simulated power consumption system. The communication units of the simulated electric energy meter and the actual electric energy meter are used to form a testable electric energy meter that is the same as the actual electric energy meter. The communication units of the simulated electric energy meter and the actual electric energy meter can communicate through the serial port, specifically, the communication units of the test device and the actual electric energy meter communicate through the serial port.

[0155] By controlling the simulated electric energy meter and communicating between the simulated electric energy meter and the actual electric energy meter, it is possible to control the communication unit of the actual electric energy meter and collect communication data, thereby facilitating functional testing.

[0156] By generating a simulated concentrator and establishing a connection between the simulated concentrator and the actual concentrator (which can be serial communication, specifically serial communication between the test device and the actual concentrator), the control of the CCO and the collection of communication data can be achieved through the control of the simulated concentrator and the communication between the simulated concentrator and the actual concentrator, thereby facilitating functional testing.

[0157] In this way, a complete simulated power system environment can be constructed to meet the functional test requirements of any communication unit of the simulated power system (such as the communication unit of the CCO or the STA) without switching the hardware environment, thereby improving the test efficiency.

[0158] Step 012: Run the test case corresponding to the function to be tested to obtain the message of the simulated power consumption system.

[0159] Among them, test cases are a very important component of software testing. It is a set of specific inputs, execution conditions, and expected results, which are used to verify whether a specific function or behavior works as expected.

[0160] In the field of communication and networking, a message refers to a unit of data transmitted on a network. A message can contain different types of information, such as text, images, audio, or control instructions.

[0161] Optionally, the function to be tested is at least one of the preset functions of the communication unit, and each preset function is configured with a corresponding test case. In this way, one or more preset functions of the communication unit that need to be tested can be tested.

[0162] Specifically, after the simulated power consumption system is constructed, the test of the communication unit can be started. The test software has preset test cases for different functions of the communication unit, and different functions of the communication unit can be tested through different test cases.

[0163] Based on the function to be tested currently being tested, the test case corresponding to the function to be tested is run, such as by establishing a separate thread to run the test case. Then, by implementing the factory pattern, the corresponding test case is obtained by the name of the current test case, and the test case is started to be executed.

[0164] After the test case is run, the control of the communication unit under test, accompanying test device and other devices in the simulated power system can be realized, so that the simulated power system can realize the corresponding function to be tested. By realizing the corresponding function to be tested by the simulated power system and collecting various communication messages in the process of the simulated power system realizing the corresponding function to be tested, the test data in the process of realizing the function to be tested can be obtained.

[0165] It can be understood that the test data during the implementation process of the function to be tested can represent the implementation status of the function to be tested, thereby realizing the test evaluation of the function to be tested.

[0166] See also Figure 5 Optionally, the message of the simulated power consumption system includes a first message, a second message and a third message, and step 012 includes:

[0167] Step 0121: obtaining, through the simulated concentrator, a first message between the simulated concentrator and the actual concentrator;

[0168] Step 0122: obtaining, through the simulated electric energy meter, a second message between the communication units of the simulated electric energy meter and the actual electric energy meter;

[0169] Step 0123: Listen to the third message of the power line between the actual concentrator and the communication unit of the actual electric energy meter.

[0170] Specifically, in the simulated power consumption system, the objects for communication mainly include the simulated concentrator, the actual concentrator, the simulated electric energy meter and the communication unit of the actual electric energy meter.

[0171] The communication path includes a communication path between the simulation concentrator and the actual concentrator, a communication path between the simulation electric energy meter and the communication unit of the actual electric energy meter, and a communication path between the actual concentrator and the communication unit of the actual electric energy meter.

[0172] Therefore, the messages of the simulated power consumption system can be divided into three types, namely the first message, the second message and the third message. The first message, the second message and the third message correspond to the communication path between the simulated concentrator and the actual concentrator, the communication path between the simulated electric energy meter and the communication unit of the actual electric energy meter, and the communication path between the actual concentrator and the communication unit of the actual electric energy meter.

[0173] The first message can be obtained through the simulated concentrator, the second message can be obtained through the simulated electric energy meter, and the third message can be obtained through the listening device. The simulated concentrator communicates with the actual concentrator through the test device, and the simulated electric energy meter communicates with the communication unit of the actual electric energy meter through the test device.

[0174] Therefore, when the test device obtains the first message, it will upload it to the simulation concentrator in the host computer, so that the simulation concentrator obtains the first message; when the test device obtains the second message, it will upload it to the simulation electric energy meter in the host computer, so that the simulation electric energy meter obtains the second message.

[0175] The listening device can intercept the third message, and the listening device is connected to the testing device, so as to send the intercepted third message to the testing device. After the testing device obtains the third message, it will also upload it to the host computer, so that the host computer can obtain each communication message in the simulated power consumption system, and realize the acquisition of test data of the whole process of realizing the function to be tested of the simulated power consumption system.

[0176] See also Figure 6 Optionally, the message of the simulated power consumption system includes a first message, a second message and a third message, and step 012 further includes:

[0177] Step 0124: parsing the first message based on the first communication class corresponding to the communication protocol between the simulated concentrator and the actual concentrator;

[0178] Step 0125: parsing the second message based on the second communication type corresponding to the communication protocol between the simulated electric energy meter and the actual electric energy meter;

[0179] Step 0126: Parse the third message based on the third communication class corresponding to the communication protocol between the actual concentrator and the actual electric energy meter.

[0180] Specifically, since the communication protocol between the simulated concentrator and the actual concentrator, the communication protocol between the simulated electric energy meter and the communication unit of the actual electric energy meter, and the communication protocol between the communication unit of the actual electric energy meter and the actual concentrator may be different, in order to process messages of different communication protocols so that the host computer can accurately parse the specific content of each message, corresponding communication protocol classes are set in the host computer for different communication protocols to implement the parsing of the corresponding communication protocols.

[0181] The communication protocol classes set by the host computer include a first communication class (ie, a simulation concentrator class), a second communication class (ie, a simulation electric energy meter class), and a third communication class (ie, a listening device class).

[0182] Among them, the analog concentrator class enables the analog concentrator to process and parse the received first message, the analog electric energy meter class enables the analog electric energy meter to process and parse the received second message, and the listening device class is used to process and parse the third message intercepted by the listening device.

[0183] Optionally, in order to realize communication with the test device, the host computer is further provided with a test communication class, and the test communication class is used to send, receive, and process messages between the test device to realize the sending and receiving of messages and the control of the test device.

[0184] For example, the host computer and the test device communicate through the network port. The test device encapsulates the messages of 1376.2, DLT646, DLT698, 1376.1 and 11612.1 protocols based on the test communication class and sends them to the host computer. After the host computer restores the message, it parses, identifies and filters the correct message and sends it to the corresponding communication class for processing. Based on these classes, the test case processes the message of the corresponding protocol to determine whether the required message is received and the correctness of the message.

[0185] In an example, the analog concentrator class is used to communicate with the CCO, and the communication protocol is 1376.2 (1376.2 concentrator local communication module interface communication protocol). It implements the organization and parsing of 1376.2 protocol messages, sends correct messages to the CCO, and waits for and receives 1376.2 protocol messages sent by the CCO for parsing and judgment.

[0186] The analog energy meter class is used to communicate with STA. The communication protocol is DLT646 (DL_T_645_2007_Multi-function Energy Meter Communication Protocol) and DLT698 (DLT698.45 Electric Energy Information Collection and Management System-Object-oriented Data Exchange Protocol). It implements the organization and parsing of DLT646 and DLT698 protocol messages, sends correct messages to STA, and waits for and receives DLT646 and DLT698 protocol messages sent by STA for parsing and judgment.

[0187] The listening device class is used to obtain power line messages, and the communication protocol is 11612.1 protocol (Low Voltage Power Line Broadband Carrier Communication Interoperability Technical Specification). It realizes receiving power line messages from the listening unit, parsing and judging.

[0188] The test communication class is used to communicate with the baseboard, and the communication protocol is the 1376.1 protocol (QGDW 10376.1—2019 Electricity Consumption Information Collection System Communication Protocol) extended protocol. The baseboard is configured (module power on and off, serial port baud rate switching, GPIO (General-Purpose Input / Output) level control, etc.) by sending 1376.1 protocol messages to the baseboard.

[0189] Step 013: Based on the message, determine the test result of the function to be tested.

[0190] Specifically, after collecting various communication messages in the process of simulating the power consumption system to realize the corresponding function to be tested, a test evaluation can be performed based on the messages to determine the test result of the function to be tested, such as test pass or test fail.

[0191] For example, for the meter reading function test of STA, by judging whether the simulated power consumption data generated by the simulated power meter is consistent with the meter reading power data obtained by the actual concentrator after reading the STA meter, it can be determined whether the meter reading function test of STA is normally implemented, thereby determining the test result. If the simulated power consumption data and the meter reading power data are consistent, it is determined that the test has passed; if the simulated power consumption data and the meter reading power data are inconsistent, it is determined that the test has failed, thereby realizing the test of the meter reading function of STA.

[0192] See also Figure 7 Optionally, step 013 includes:

[0193] Step 0131: Determine each preset test condition satisfied by the message;

[0194] Step 0132: Determine the test result of the function to be tested based on the preset test conditions that have been met.

[0195] Specifically, after the host computer receives the message (such as the first message, the second message and the third message) of the simulated power system during the running of the test case, the message of the simulated power system can be tested and evaluated to obtain the test results.

[0196] The specific process of test evaluation is as follows:

[0197] First, each function to be tested is set with one or more corresponding preset test conditions. The message of the simulated power system can be used to determine whether the function to be tested meets each preset test condition. Based on the preset test conditions met by the message of the simulated power system, the test evaluation of the function to be tested can be realized and the test result can be obtained.

[0198] Optionally, when all preset test conditions are met, the test result of the function to be tested is determined to be a test pass; when any preset test condition is not met, the test result of the function to be tested is determined to be a test fail.

[0199] In other words, the test is considered passed only when all preset test conditions are met. Only then can the next function to be tested be tested. If any preset test condition is not met, the function to be tested is considered to have failed. In this way, by setting higher test requirements, the stability of the functions to be tested that have passed the test is guaranteed.

[0200] Optionally, the preset test condition includes at least one of the following:

[0201] Whether the message corresponding to the function to be tested is received. For example, in the communication process function test at power-on, determine whether the response message is received.

[0202] Whether the message corresponding to the function to be tested is received within the specified time. For example, in the communication process function test of STA, when STA is not communicating with the simulated power meter, it will read the communication address of the power meter every preset period (such as 5 minutes) to maintain the heartbeat, and judge whether the message corresponding to the function to be tested is received within the specified time by judging whether the request message to read the communication address of the power meter is received every 5 minutes.

[0203] Whether the number of received messages corresponding to the function to be tested is greater than a preset ratio. For example, whether the meter reading rate of the CCO for STAs within a preset time period reaches 98%.

[0204] Whether the received message corresponding to the function to be tested complies with the corresponding communication protocol standard. For example, when performing a 1376.2 protocol test, determine whether the received message meets the requirements of the 1376.2 protocol.

[0205] Whether the received message corresponding to the function to be tested is consistent with the configuration parameters of the test case. For example, in the version information setting and query function test, whether the version information set in the test case is consistent with the version information in the message containing the actual queried version information.

[0206] Whether the received message corresponding to the function to be tested is consistent with the simulated power consumption data. For example, in the meter reading function test, whether the power data reported by STA and CCO is consistent with the simulated power consumption data generated by the simulated power meter.

[0207] Whether the functions of the test case are executed normally. For example, in the upgrade function test, after the test is completed, whether the version of CCO or STA is consistent with the version of the upgrade file issued by the test case.

[0208] Optionally, after the test results are determined, information may be displayed based on the test results.

[0209] For example, when testing the meter reading function, if the test result is passed, the host computer can display information through a display screen or speaker or other prompting devices, so that the test personnel can quickly understand the test result of the meter reading function, and then test the next function to be tested when the test passes, so as to improve the test efficiency. If the test fails, the test result is recorded to facilitate the subsequent debugging of the communication unit for the function that failed the test.

[0210] Optionally, the test result display scheme includes at least one of the following:

[0211] (1) In the test interface, the selected test items (i.e., the functions to be tested) are displayed in a table format, showing the test item name, test item duration, test item results, test item result description and other information, which will be updated in real time during the test.

[0212] (2) During the test, the interface will display information such as the number of tests completed and the number of tests passed.

[0213] (3) Record relevant test data, test results, etc. through test logs.

[0214] (4) Test data and results will be saved in the database.

[0215] (5) The test report interface can query historical test records, preview or print test reports.

[0216] Optionally, the test software can manage the test results, the specific process is as follows:

[0217] (1) Log management: The software log contains necessary process information and all communication messages, which are displayed on the graphical interface and saved in the local log file.

[0218] (2) Data management: The software stores test data and test results in the sqlite database. Data management enables the addition, deletion, modification and query of the database.

[0219] (3) Report management: realize the query of test records, preview and print functions of test reports.

[0220] The test method of the communication unit of the present application generates a simulated concentrator and a simulated electric energy meter, which together with the communication unit of the actual concentrator and the actual electric energy meter constitute a complete simulated power consumption system, wherein the simulated electric energy meter generates simulated power consumption data, and the communication unit of the simulated electric energy meter and the actual electric energy meter together constitute a complete electric energy meter. After completing the construction of the simulated power consumption system, the test case corresponding to the function to be tested that needs to be tested can be run, and the message in the simulated power consumption system during the running of the test case can be obtained. The test result of the function to be tested can be quickly determined by the message of the simulated power consumption system, and the automated test of the function to be tested can be realized. Moreover, since a complete simulated power consumption system is constructed, when testing different functions to be tested, it is only necessary to replace the corresponding test case without switching the accompanying test device (i.e., the device that is essential for the communication unit to be tested to realize the function). Compared with the low test efficiency of switching the corresponding accompanying test device when testing different functions, the test efficiency is significantly improved.

[0221] See also Figure 8 In some embodiments, the testing method of the present application further includes:

[0222] Step 014: Display the use case configuration interface;

[0223] Step 015: Obtain at least one of the selection operation received by the use case selection module and the editing operation received by the use case editing module of the use case configuration interface to generate a test case corresponding to the function to be tested.

[0224] Specifically, when testing the function to be tested, the tester can configure the corresponding test case through the host computer.

[0225] During the configuration process, the monitor of the host computer will realize the software interface. The tester can enter the use case configuration interface by controlling the host computer. At this time, the monitor shows the use case configuration interface.

[0226] The use case configuration interface includes a use case selection module and a use case editing module.

[0227] The use case selection module can be a drop-down box. The tester clicks the drop-down box to display the various test cases preset in the test software. The tester can select the test case corresponding to the function to be tested, thereby selecting the test case corresponding to the function to be tested through the selection operation.

[0228] The case editing module can configure the parameters of the selected test case. For example, different customers have different customer version information, and different power grid companies support different extension protocols of power line carrier communication protocols (such as 1376.2 protocol). Targeted configuration is required to achieve targeted testing of different customer versions and power grid companies, thereby ensuring the test effect.

[0229] Optionally, after configuring parameters for different customer versions, different power grid companies, etc., the configured test cases can be saved and saved in the use case selection module, so that when the use cases are subsequently configured for specific customer versions, specific power grid companies, etc., the test cases saved in the use case selection module can be reused, thereby improving the efficiency of the use case configuration, which is conducive to improving the testing efficiency.

[0230] Optionally, the same function of the communication unit may correspond to multiple test cases, and the multiple test cases are set for different customer versions and different power grid companies, thereby reducing the frequency of parameter configuration by testers (i.e., in most cases, only test case selection is required without parameter configuration), further improving test efficiency.

[0231] After the use case selection and parameter configuration are completed, the test case corresponding to the function to be tested can be generated, and the function to be tested can be tested by running the test case.

[0232] Optionally, the test case is serialized to generate and store an XML (eXtensible Markup Language) file corresponding to the test case.

[0233] XML is a standard file format for marking data, designed to transmit and store data. XML is designed for cross-platform and cross-application data exchange, and is widely used in Web services, configuration files, data exchange protocols, and other fields.

[0234] XML serialization and deserialization of test cases refers to the process of converting test case objects into XML formatted text and restoring XML formatted text into test case objects, so as to save the status of test cases, transfer test case information, or exchange data between different systems.

[0235] XML serialization refers to converting an object into a string in XML format, which makes it easy to store or transmit data. XML deserialization refers to converting a string in XML format back into an object.

[0236] In order to facilitate an overall understanding of the present application, specific examples are provided below for illustration.

[0237] In an example, the test system tests the meter reading function of the communication unit of the actual electric energy meter. Fig. 9 , the test process is as follows:

[0238] (1) Initialization steps: simulate the concentrator and simulate the electric energy meter (corresponding to Fig. 9 Virtual electric energy meter in the real concentrator, the communication unit of the real electric energy meter, the test device, the listening device (corresponding to Fig. 9 The listening unit in the device is initialized to configure the communication address, frequency band, etc., and restore the parameters of each device to the initial state.

[0239] (2) Test steps: The test device will send control instructions to the actual concentrator to control the actual concentrator to send meter reading messages to the communication unit of the actual electric energy meter. At this time, the listening device can obtain the communication data between the actual concentrator and the actual electric energy meter by listening to the data of the power line between the actual concentrator and the actual electric energy meter as test data; then, the communication unit of the actual electric energy meter collects simulated power consumption data from the test device (serial port communication data capture), and gives the collected simulated power consumption data to the actual concentrator to complete the meter reading of the simulated power consumption data.

[0240] The communication data between the test device and the actual electric energy meter, and the communication data between the test device and the actual concentrator can be directly obtained by the test device. The communication data between the actual concentrator and the actual electric energy meter can be obtained by the monitoring device monitoring the data of the power line between the actual concentrator and the actual electric energy meter, thereby obtaining the test data in the entire test process (i.e., the communication data between the test device and the actual electric energy meter, the communication data between the test device and the actual concentrator, and the communication data between the actual concentrator and the actual electric energy meter).

[0241] The test device uploads the test data to the host computer, and the host computer evaluates the test data to determine the test results. For example, for the meter reading test, if the power consumption data collected by the actual energy meter and the power consumption data obtained by the actual concentrator meter reading are consistent with the simulated power consumption data generated by the test device, it can be determined that the meter reading function is normal and the meter reading function test has passed. If the power consumption data collected by the actual energy meter or the power consumption data obtained by the actual concentrator meter reading are inconsistent with the simulated power consumption data generated by the test device, it can be determined that the meter reading function is abnormal and the meter reading function test has failed.

[0242] After the host computer determines the test results, it can record and display the test results, which is convenient for testers to view in time and maintain the device under test based on the test results.

[0243] In another example, the test system tests the communication process function of the communication unit of the actual electric energy meter. The description of the communication process function when powered on is as follows:

[0244] After the STA is powered on, it first detects the 645 protocol. After receiving a normal response, it stops detecting the DL / T 645 protocol and detects the DL / T 698 protocol at the same baud rate. If no DL / T 645 protocol response is received, it will actively detect the DL / T 698 protocol.

[0245] STA is not connected to the analog energy meter (corresponding to Fig.10 In the case of communication with the virtual electric energy meter in the example, the communication address of the analog electric energy meter is read at a preset period (such as 5 minutes) to maintain the heartbeat.

[0246] When STA detects the simulated energy meter, normal communication can be carried out and the test verification is carried out by meter reading.

[0247] Please combine Fig.10 , the test process is as follows:

[0248] After power-on, observe whether the detection message of DL / T 645 and DL / T 698 protocols is received through the simulated electric energy meter. If not, the test fails; if yes, no response is made, and wait for the next round of detection by STA to determine whether the detection cycle is consistent with the heartbeat cycle (parameters are configured by the test case editing module of the test case, usually 5 minutes). If not, the test fails. If consistent, respond to the detection message. After receiving the response, STA should no longer continue to detect and wait for two heartbeat cycles to observe whether STA continues to detect during this period. If there is detection, the test fails. If not, perform a round of meter reading and observe whether STA correctly sends the reading message (DL / T645 protocol) through the simulated electric energy meter. If no message is sent, the test fails. Otherwise, the test passes and the next functional test is performed.

[0249] In another example, the test system tests the setting and query module identification (Identity document, ID) function of the actual concentrator. The setting and query module ID function is used to determine whether the module ID information query and setting function of the communication unit of the actual concentrator is normal. Fig.11 , the test process is as follows:

[0250] (1) Initialization steps: simulate the concentrator and simulate the electric energy meter (corresponding to Fig.11 Virtual electric energy meter in the real concentrator, the communication unit of the real electric energy meter, the test device, the listening device (corresponding to Fig.11 The listening unit in the device is initialized to configure the communication address, frequency band, etc., and restore the parameters of each device to the initial state.

[0251] (2) Test steps: During the test, a module ID information query message is sent to the communication unit of the actual concentrator through the test device to observe whether the communication unit of the actual concentrator can normally reply to the query message. If so, the module ID information is saved for restoration of the module ID information after the test is completed; then, according to the ID information configured in the scheme, a module ID setting message is sent to the communication unit of the actual concentrator, and the communication unit of the actual concentrator is waited for to respond with a successful setting message. After the communication unit of the actual concentrator responds, the module ID is queried again.

[0252] The test device can obtain the queried module ID, and upload the queried module ID and the set module ID to the host computer. The host computer determines whether the queried ID information is consistent with the set ID information. If not, the test fails. The test device can control the communication unit of the actual concentrator to restart the module and query again, so as to test whether the module restart will cause the module ID to be lost. If lost, the test fails, otherwise the test passes, and the next test is performed after the module ID is restored.

[0253] According to the method described in the above embodiment, the present application embodiment also provides a testing device 300 for executing the steps in the above testing method.
