Description

Technical Field

[0001] This invention relates to the field of intelligent diagnostic equipment technology, specifically to a remote module anomaly intelligent diagnostic device and method on a centralized procurement area concentrator. Background Technology

[0002] With the upgrading of power grid centralized data collection equipment and the arrival of the big data era, the State Grid Corporation of China (SGCC) is collecting data on an increasingly wider and denser scale. This necessitates higher timeliness for data collection tasks. However, the distribution of centralized data collection equipment is highly dispersed, especially in remote or mountainous areas where signal strength is extremely unstable or only a weak signal from a single communication provider exists. Therefore, we need to test the network login status of SIM cards from different operators in the area where the concentrator is located for the SGCC's reference, enabling them to select a more suitable SIM card usage scheme for that location.

[0003] Currently, the remote module communication status on the remote procurement area concentrator can only simply identify whether the SIM card is connected to the main station, or some concentrator manufacturers will display the 4G module's network connection status on the screen. However, the traditional remote module communication technology on the remote procurement area concentrator is not effective. Specifically, the problems with the concentrator's use of the remote communication module are: 1. It cannot accurately reflect the reasons for errors when the SIM card connects to the State Grid main station through the remote communication module; 2. It cannot obtain the SIM card information, which is not conducive to SIM card management; 3. It cannot record the interaction information between the concentrator and the remote communication module, so there is no data source for troubleshooting when problems occur during use. Summary of the Invention

[0004] To address the shortcomings and deficiencies of existing technologies in remote module communication on remote mining concentrators, this invention provides an intelligent diagnostic device for remote module anomalies on mining concentrators.

[0005] The present invention achieves the above objectives by adopting the following technical solution: A remote module anomaly intelligent diagnostic device for a centralized procurement area concentrator includes a mobile control terminal, a concentrator body, a remote channel tester base, a 4G communication module, and a monitoring device. The mobile control terminal is used for secure login to the State Grid main station APP for identity verification and can view information data and perform SIM card information detection services. One end of the concentrator body is connected to a power line carrier, and a mounting slot is provided on one side, where a remote communication module interface is also located. The monitoring device maintains a signal connection with the mobile control terminal via Bluetooth. The monitoring device has a power strip interface on one side and a Type-C interface on the other side, the Type-C interface being used for communication maintenance. The 4G communication module maintains a signal connection with the monitoring device via the power strip interface. In the installed state, the two devices can also maintain a connection through an adapter installation method between the monitoring device and the mounting slot. The signal end of the monitoring device and the remote communication module interface maintain a signal connection through a monitoring communication channel. When performing a monitoring task, the monitoring device automatically opens the monitoring communication channel between the 4G communication module and the concentrator. The remote channel tester base is equipped with an external antenna on its top and multiple evenly distributed operation buttons on one side of its front. An LED display screen is also located on the outer wall of the base, displaying the testing progress in real time. The remote channel tester base and the monitoring device maintain a signal connection via a detection communication channel. When the device performs a SIM card network testing task, the monitoring device can intelligently identify the inserted remote channel tester base and open the detection communication channel between the monitoring device and the remote channel tester base. Then, it performs the task of logging into the State Grid main station via the remote communication chip of the 4G communication module and the external antenna. Furthermore, an adapter for the monitoring device is installed on one side of the remote channel tester base. The device secures the card in place; the mobile control terminal sends network communication parameters for logging into the main station via Bluetooth channel, ensuring no tasks are executed before initiating either network login detection or SIM card information detection; alternatively, the SIM card slot's network login task and the external 4G communication module's network login task can be executed via the buttons on the remote channel tester's base meter; the SIM card information detection includes information such as the SIM card's manufacturer, signal strength, phone number, CCID, IMEI, network registration mark, data connection mark, main station connection mark, and main station login mark; simultaneously, each detection operation generates and stores corresponding timestamp detection information, which can be queried by the mobile control terminal's APP.

[0006] As a preferred technical solution, the mobile control terminal is the State Grid handheld device.

[0007] A further preferred technical solution: The mobile control terminal further includes a login module, a Bluetooth protocol connection module, a command execution module, a data transmission module, and a feedback analysis module. The login module is used by maintenance personnel to open the corresponding APP, connect to the State Grid main station via account and password, and obtain the main station's identity authentication. The Bluetooth protocol connection module is used to connect to the monitoring device of the remote channel via Bluetooth and read the monitoring frames in the on-site monitoring device. The command execution module is used to encrypt and package the monitoring frames within the time period required by the State Grid handheld device. The data transmission module is used to transmit the packaged monitoring frame data from the command execution module to the State Grid main station via the 5G network transmission protocol. The feedback analysis module is used to make judgments on the on-site situation based on the viewing and analysis of the on-site monitoring frames and to provide support for maintenance operations.

[0008] A further preferred technical solution: The bottom of the remote channel tester base is also provided with a type-C power supply interface for power supply by a mobile power source.

[0009] A further preferred technical solution: The concentrator is also equipped with a 4V power supply module, which supplies power to the monitoring device through a remote communication module interface, and the operating power does not exceed 5W.

[0010] A further preferred technical solution: The remote channel tester is also provided with a battery mounting slot on one side of the base, and a lithium battery is adapted to be installed inside the battery mounting slot.

[0011] A further optimized technical solution: During SIM card testing and installation, the 4G communication module is unplugged from the remote communication module interface of the concentrator, inserted into the top of the monitoring device, and then the combined monitoring device is inserted into the base table of the remote channel tester to perform the testing operation; when multiple other related SIM cards need to be tested, they can be inserted into the other 3 card slots of the tester base table.

[0012] A further preferred technical solution: The monitoring device is also equipped with a data comparison and analysis module. The data comparison and analysis module will analyze the monitored data to determine which step the current network process has entered, whether the parameters sent are the same as the parameters of the main station, and what kind of error the error response is. This analysis can be queried by operation and maintenance personnel.

[0013] A further preferred technical solution: The State Grid handheld device can upgrade the system and functions of the monitoring device and the remote channel tester base meter via Bluetooth; the monitoring device can be maintained via communication through the Type-C port.

[0014] A diagnostic method for a remote module anomaly intelligent diagnostic device on a centralized procurement area concentrator, wherein the method for performing the detection and diagnostic operation using the aforementioned diagnostic device is as follows: S1: When the State Grid mobile app is logged in, a command is issued to start the detection task of logging into the State Grid main website; S2: Staff confirm whether the 4G communication module and SIM card are inserted into the card slot; including whether the 4G communication module is inserted or not. S3: With the 4G communication module inserted, the staff first performs the corresponding hardware initialization according to the pin definition of the remote communication module interface in the State Grid Concentrator Type I General Technical Specification, and then performs APP software initialization to obtain the SIM card insertion status. S4: Obtain basic information about the SIM card and send the main station IP and other related network parameters; among which, the SIM card information includes the SIM card operator, signal strength, mobile phone number, CCID, IMEI, network registration mark, data connection mark, connection to main station mark, and login to main station mark; S5: Initiate connection to the master station. According to the communication requirements of the State Grid Corporation of China enterprise standard Q / GDW1376.3--2012, use AT commands to obtain information such as operator information, signal strength, CCID, and IM time, connect to the base station, send network parameters, register the network, and connect to the specific server address; the concentrator includes a successfully connected state and an unsuccessfully connected state. S6: Upon successful connection, the encrypted login master station confirms the connection to the State Grid master station IP server. It then sends a login frame corresponding to the concentrator address in the network parameters according to the State Grid Corporation's enterprise standard Q / GDW1376.1--2022 protocol and encrypts it using the State Grid ESAM chip. Upon receiving the encrypted frame, the State Grid master station decrypts the data frame using the corresponding ESAM decryption server, verifies whether the data frame conforms to the above protocol format, and performs data frame verification to ensure data integrity. It then checks that the concentrator address is a valid address registered in the database and replies with an encrypted login frame. The host, upon receiving the encrypted frame, decrypts it using the ESAM chip to determine if the login was successful. S7: Generate network login detection results for the State Grid main station. Based on the process of remotely connecting to the main server and the feedback of login information, generate detection results with information such as generation time, card slot position, connection operator flag, parameter setting flag, network registration flag, connection to main station flag, and login to main station flag. S8: In step S2, when no 4G communication module is inserted, the slave device initializes the network chip, performs software and hardware initialization according to the datasheet of the network communication chip used by the slave device, and obtains the SIM card insertion status. S9: Continuing from step S8, obtain the basic information of the SIM card and send the main station IP and other related network parameters; among which, the SIM card information includes the SIM card operator, signal strength, mobile phone number, CCID, IMEI, network registration mark, data connection mark, connection to main station mark, and login to main station mark; S10: Initiate connection to the master station. According to the communication requirements of the State Grid Corporation of China enterprise standard Q / GDW1376.3--2012, use AT commands to obtain information such as operator information, signal strength, CCID, and IM time, connect to the base station, send network parameters, register the network, and connect to the specific server address; the monitoring device includes a successful connection status and a failed connection status; when the monitoring device is in a failed connection status, the program proceeds to step S7; S11: When the monitoring device is successfully connected, it sends an encrypted login confirmation reply to the main station. After confirming the connection to the State Grid main station IP server, it sends a login frame corresponding to the concentrator address in the network parameters according to the State Grid Corporation of China's enterprise standard Q / GDW1376.1--2022 protocol and encrypts it using the State Grid ESAM chip. After receiving the encrypted frame, the State Grid main station decrypts the data frame using the corresponding ESAM decryption server, then verifies whether the data frame conforms to the format of the above protocol and performs data frame verification to ensure data integrity. It then verifies that the concentrator address is a valid address registered in the database and replies with an encrypted login frame. After receiving the encrypted frame, the host decrypts it using the ESAM chip to determine whether the login is successful. Then the program proceeds to step S7. S12: When switching hardware data lines where there is an undetected SIM card slot, the process jumps from step S11 to step S8.

[0028] In this embodiment, the remote channel tester base meter 6 is equipped with an external antenna 4 at its top and multiple evenly distributed operation buttons 7 on one side of its front. An LED display screen 8 is also provided on the outer wall of the remote channel tester base meter 6, which can display the testing progress in real time. The remote channel tester base meter 6 and the monitoring device 12 maintain a signal connection through a detection communication channel 15. When the device performs a SIM card network detection task, the monitoring device 12 can intelligently determine the inserted remote channel tester base meter 6 and open the detection communication channel 15 between the monitoring device 12 and the remote channel tester base meter 6. Then, it performs the task of logging into the State Grid main station through the remote communication chip of the 4G communication module 11 and the external antenna 4. A fastening slot 18 for mounting the monitoring device 12 is also provided on one side of the remote channel tester base meter 6.

A battery mounting slot 25 is also provided on one side of the remote channel tester base meter 6, and a lithium battery 26 is installed inside the battery mounting slot 25.

[0029] In this embodiment, the mobile control terminal 10 sends the network communication parameters for logging into the master station via Bluetooth. After ensuring that no tasks are being executed, it initiates either network login detection or SIM card information detection. Alternatively, the task of starting the SIM card in the SIM card slot 5 to log into the master station and the task of starting the external 4G communication module 11 to log into the master station can be executed respectively via the buttons on the base table 6 of the remote channel tester. The SIM card information detection includes information such as the SIM card's operator, signal strength, phone number, CCID, IMEI, network registration mark, data connection mark, master station connection mark, and master station login mark. At the same time, each detection operation generates and stores detection information with a corresponding timestamp, which can be queried by the APP of the mobile control terminal 10.

[0030] In this embodiment, during the SIM card testing and installation operation, the 4G communication module 11 is unplugged from the remote communication module interface 3 of the concentrator, inserted into the top of the monitoring device 12, and then the combined monitoring device 12 is inserted into the base table 6 of the remote channel tester to perform the testing operation. When multiple related SIM cards need to be tested, they can be inserted into the other three card slots of the tester base table. The main station obtains monitoring data operation process: Open the corresponding APP on the State Grid handheld device and log in to the internal account; connect to the remote channel monitoring device and read the complete monitoring data message and intelligent analysis content; the intelligent analysis content is based on the data part related to network login in the monitoring message, and uses the State Grid Corporation enterprise standard Q / GDW1376.3--2012 protocol to parse each interaction step in the network login to obtain the corresponding occurrence time and conclusion; after the handheld device extracts the monitoring data and analysis results, it uploads them to the State Grid internal server for recording.
