Description

Technical Field

[0001] This invention relates to the field of meteorological satellite technology, and in particular to a method for remote monitoring and parameter adjustment of a meteorological satellite data collection platform. Background Technology

[0002] Meteorological satellite data collection platforms are the core field terminal equipment of the integrated space-ground meteorological monitoring network. They are widely deployed in unmanned field scenarios such as mountains, water areas, and deserts. They are mainly responsible for collecting environmental data such as meteorology, hydrology, air quality, and geological disasters, and uploading the monitoring data to the ground center station in real time through a dedicated satellite link. They are important data support equipment for meteorological early warning, hydrological scheduling, environmental management, and disaster prevention and mitigation. Currently, the traditional DCP equipment that has been deployed on a large scale in the market all adopt a local fixed configuration mode. After the equipment is deployed at the factory, its core operating parameters such as transmission channel, start transmission time, data transmission interval, and environmental data collection cycle can only be configured and modified through a professional computer and a dedicated serial cable connected to the local debugging serial port of the equipment. Once the parameters are fixed, they cannot be updated automatically. When the field monitoring environment changes, the satellite communication channel is interfered with, the meteorological emergency monitoring mission is launched, or the equipment has abnormal parameters or deadlock failure, professional operation and maintenance personnel must be dispatched to the field deployment site for manual debugging and parameter modification.

[0003] In summary, traditional operation and maintenance methods have the following drawbacks: 1. DCP equipment is deployed over a wide area and in remote locations, resulting in extremely high costs for manual on-site operation and maintenance, consuming a large amount of manpower, material resources, and time; 2. On-site operation and maintenance response is slow, making it unable to cope with emergency scenarios such as sudden extreme weather or channel failures, which can easily lead to monitoring data interruption and insufficient data acquisition accuracy; 3. Many old, low-cost DCP devices are not designed with independent debugging serial ports, only retaining a single service data serial port, making conventional remote transformation solutions incompatible and making intelligent operation and maintenance upgrades of the equipment difficult; 4. Most existing transformation solutions require replacing the main equipment or tampering with the core firmware, resulting in high transformation costs, poor compatibility, and easy disruption of the equipment's original satellite data transmission services, making stability unreliable.

[0004] In summary, this application proposes a method for remote monitoring and parameter adjustment of a meteorological satellite data collection platform. Summary of the Invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes a method for remote monitoring and parameter adjustment of a meteorological satellite data collection platform.

[0006] This invention proposes a method for remote monitoring and parameter adjustment of a meteorological satellite data collection platform, comprising two remote control schemes that can be implemented independently or combined appropriately, as detailed below:

[0007] Option 1: For DCP devices with independent external debugging serial ports, connect a remote communication module to the external debugging serial port of the DCP device. The remote communication module adopts a 4G DTU device to establish a bidirectional transparent transmission channel between the remote monitoring center and the DCP debugging serial port through the 4G network. Relying on the transparent transmission channel, remote query and monitoring of the working status of the DCP device can be achieved, as well as remote configuration and modification of the DCP transmission channel, start transmission time, transmission time interval, and data acquisition cycle parameters.

[0008] The specific logical steps are as follows:

[0009] S101: Hardware Adaptor Connection: Connect the serial port of the 4G DTU to the external debugging serial port of the DCP device to complete the power supply and communication line construction, and ensure that the 4G DTU and the DCP satellite launch main service are completely isolated.

[0010] S102: Network Channel Establishment: The 4G DTU powers on and connects to the network, automatically establishing a long connection with the remote monitoring center and building a stable two-way transparent data transmission channel;

[0011] S103: Remote Status Monitoring: The remote monitoring center issues a device status query command according to the DCP device's private debugging protocol. The command is transmitted to the DCP main control unit via the 4G DTU. The DCP collects its own operating voltage, satellite signal strength, current transmission parameters and device operating status data and transmits them back to the remote monitoring center via the same route.

[0012] S104: Remote parameter adjustment: The remote monitoring center issues parameter modification instructions based on channel interference, satellite overpass time, and emergency monitoring needs. The DCP main control unit receives and parses the instructions, updates the core working parameters, and writes them into the non-volatile memory to complete parameter solidification.

[0013] S105: Result Verification Feedback: After the DCP device completes the parameter update, it sends the latest configuration parameters and execution results back to the remote monitoring center to complete the parameter verification and filing.

[0014] Option 2: For DCP devices that do not have an independent external debugging serial port and are only configured with a single service data serial port, an external circuit including an IO activation line and a serial port multiplexing line is built. The remote monitoring center issues an activation command to wake up the DCP device, which switches the DCP device to remote configuration mode and listens to the service data serial port. By reusing the DCP's unique service data serial port, remote monitoring of device status and dynamic adjustment of working parameters are completed.

[0015] The specific logical steps are as follows:

[0016] S201: Hardware modification and setup: Complete the wiring adaptation of the remote communication module, IO activation signal line and analog switch to ensure that the IO activation signal is independently controllable and the serial communication line can be seamlessly switched.

[0017] S202: Remote wake-up activation: When the remote monitoring center sends a wake-up command, the GPIO pin of the remote communication module outputs a high-level pulse of preset duration or a continuous high level, triggering an external interrupt of the DCP main control chip;

[0018] S203: Mode Switching Listening: After the DCP device detects the activation interrupt signal, it suspends regular data acquisition and satellite launch services, automatically switches to remote configuration mode, and continuously listens for communication data on the service data serial port;

[0019] S204: Parameter Interaction Configuration: The remote monitoring center sends query or configuration commands through the 4G network, which are transmitted to the DCP service data serial port via the remote communication module. The DCP parses and executes the commands to complete the status query or parameter modification and fixation.

[0020] S205: Exit Configuration Mode: After the parameters are configured, the remote monitoring center issues an exit command, or through the device's built-in timeout mechanism, the DCP device automatically exits the configuration mode, releases the IO activation signal, and resumes normal monitoring and satellite data transmission services.

[0021] Preferably, in Scheme 1, the external debugging serial port is a dedicated debugging interface with RS-232 or TTL-232 level, which is physically isolated and logically independent from the service data serial port of the satellite transmitter connected to the DCP device. The 4G DTU device works in pure transparent transmission mode throughout the process, and there is no parsing, tampering, or forwarding delay for the configuration query commands issued by the remote monitoring center and the status data returned by the DCP device.

[0022] Preferably, in the second scheme, the external circuit includes a remote communication module and an IO activation signal line. The remote communication module has a built-in controllable GPIO pin, and the GPIO pin is connected to the external interrupt wake-up pin of the DCP main control chip through the IO activation signal line. The communication serial port of the remote communication module is connected to the DCP service data serial port in parallel through an analog switch.

[0023] The commands to modify the parameters "transmission channel, start transmission time, and transmission time interval" are transmitted through the same serial communication line that is connected in parallel with the IO activation signal line.

[0024] Preferably, in the second scheme, after receiving the IO activation signal, the DCP device switches from the normal operation mode or the low-power sleep mode to the "remote configuration mode". In this mode, the DCP device actively listens to its data serial port and parses the received instructions.

[0025] Preferably, the specific logical steps of S103 are as follows:

[0026] S1031: Command Encapsulation and Issuance: The remote monitoring center assembles a standardized status query command frame according to the original manufacturer's private debugging protocol of the DCP device. The command frame contains the device's unique ID, status query command code, check code, and frame header and frame tail identifiers. The remote monitoring center issues the query command to the 4G DTU device through the 4G network.

[0027] S1032: Transparent Transmission Input: The 4G DTU operates in pure transparent transmission mode, without parsing, tampering with, or filtering the instruction content. It completely transmits and forwards the status query instruction to the external debugging serial port of the DCP device to complete the monitoring instruction input.

[0028] S1033: Equipment data sampling: The DCP main control unit receives and verifies the query command. After the command verification is successful, it synchronously collects four types of core operating data, including the equipment's real-time operating voltage, real-time satellite signal strength, currently fixed transmission configuration parameters, and equipment operating status identification data.

[0029] S1034: Data Quality Screening Calculation: The DCP main control unit performs noise filtering and validity assessment on the collected raw sensor and operational data, eliminates abrupt and abnormal data, and quantifies the reliability of the data based on the effective determination of the equipment operational data to obtain standardized and valid operational data. The specific calculation formula is as follows:

[0030] ;

[0031] in To determine the validity of a single type of operational data, X represents the real-time sampled data for this instance, which includes two types of dynamic sampled data: real-time operating voltage and real-time satellite signal strength. The historical steady-state baseline values ​​for the corresponding parameters are the average steady-state data under normal, undisturbed operating conditions, pre-stored in the DCP non-volatile memory. The environmental stability coefficient, with a value range of [0.6, 1.0], is used when the weather is clear and electromagnetic interference is weak. =1.0, δ decreases accordingly in outdoor environments such as thunderstorms, sandstorms, and strong electromagnetic interference, and the system presets the effective data threshold. If η≥0.8, the sampled data is considered valid; if η<0.8, it is considered abnormal data with interference distortion and is discarded directly, and will not be included in subsequent response encapsulation and status statistics.

[0032] S1035: Response data encapsulation and transmission: The DCP encapsulates the filtered valid operating voltage, satellite signal strength, transmission parameters, and equipment operating status data into response frames according to the private protocol, and sends them to the 4G DTU via the debug serial port.

[0033] S1036: Central parsing, displaying, and archiving: The 4G DTU transmits response data to the remote monitoring center. The monitoring center parses the response frames, verifies the data integrity and accuracy, and after parsing, visualizes the device's operating status and automatically archives it to the device operation and maintenance database.

[0034] Preferably, in step S104, the remote parameter allocation process includes a satellite channel quality determination mechanism, which determines the channel communication status through the channel integrated quality coefficient. The corresponding calculation formula is as follows: ;

[0035] in The channel overall quality coefficient, Real-time satellite signal strength for DCP equipment. The current ambient background noise intensity, The preset channel data packet loss rate is set to a value range of [0,1], and the preset channel quality threshold is also set. ,when If interference is detected in the channel, the remote monitoring center will automatically trigger the DCP transmission channel and transmission interval parameter adjustment command.

[0036] Preferably, in step S202, the remote wake-up activation process employs adaptive pulse duration control, the calculation formula of which is: ;

[0037] in For the effective pulse duration of IO activation, This is the minimum wake-up response time for the DCP main control chip. This is the environmental disturbance compensation coefficient, with a value range of [1.0, 1.5]. Real-time transmission latency for 4G communication links.

[0038] Preferably, the specific logical steps of S204 are as follows:

[0039] S2041: Remote command delivery encapsulation: The remote monitoring center generates corresponding DCP status query commands or parameter configuration commands based on the on-site monitoring conditions, satellite channel quality, and emergency monitoring level. The commands are encapsulated according to the DCP private serial port protocol. The frame structure includes a frame header, device ID, command function code, parameters to be configured, CRC check code, and frame tail. The commands are then delivered to the on-site remote communication module via the 4G wireless network.

[0040] S2042: Communication module transparent forwarding: The remote communication module receives 4G downlink commands, completes the protocol conversion from network data to serial port data, does not parse or tamper with the command content, and forwards the standard serial port commands to the DCP service data serial port that is in the listening state;

[0041] S2043: DCP command validity verification: The DCP main control unit continuously listens to the service serial port data stream. After receiving the serial port command, it first matches the unique device ID and verifies the CRC check code to filter out valid commands for the local machine and filter out broadcast miscellaneous packets, interference garbled characters and invalid commands that are not local machines.

[0042] S2044: Adaptive Parameter Calculation: The DCP parses valid configuration instructions, obtains the target configuration baseline parameters issued by the center, and combines them with the current satellite channel status, field environment interference level, and meteorological emergency level to complete adaptive parameter correction calculations and achieve optimal parameter configuration. The correction formula used is as follows:

[0043] ;

[0044] in The final configuration parameters include the revised transmit time interval and data acquisition period. The baseline configuration parameters issued by the remote monitoring center. For meteorological emergency level coefficients, conventional steady-state monitoring scenarios For emergency monitoring scenarios involving heavy rain, typhoons, and floods, the value range is (0, 0.5). The higher the emergency level, the larger the value, and the higher the number of data collection and transmission frequencies after parameter updates. The channel transmission reliability coefficient has a value range of [0.8, 1.0]. The lower the channel signal-to-noise ratio, the higher the packet loss rate. The smaller the value, the better it is used to compensate for data loss caused by channel instability;

[0045] S2045: Parameter Firmware Storage: DCP writes the calculated and corrected final parameters into the non-volatile Flash memory of the device's main controller, overwriting the original firmware parameters. The device can load the new parameters and run without restarting, thus permanently firming the working parameters.

[0046] S2046: Execution result response feedback: After the parameter configuration is completed, DCP generates a response frame containing a comparison of the old and new parameters, the configuration status code, and the device operating status. This frame is then fed back to the remote communication module via the service serial port and finally uploaded to the remote monitoring center to complete the configuration archiving and verification.

[0047] Preferably, in step S205, the device's built-in timeout mechanism satisfies the configuration duration determination formula as follows: ,in Configure the real-time dwell time for DCP mode. The value is 30 seconds, which is the minimum effective configuration interaction duration. The value is 120s; when > When there is no valid command interaction on the serial port, DCP automatically exits the remote configuration mode.

[0048] Preferably, the specific logical steps of S203 are as follows:

[0049] S2031: Interrupt signal identification and judgment: The DCP main control chip polls the level status of the external wake-up pin in real time. When it detects the level pulse signal output by the GPIO pin of the remote communication module, it triggers an external interrupt, synchronously identifies the pulse width and level amplitude of the activation signal, filters out jitter noise and false interrupt signals generated by transient interference, and determines whether it is a valid remote activation signal.

[0050] S2032: Routine Service Suspension Calculation: DCP obtains the current device runtime sequence status and dynamically calculates the service suspension duration based on the remaining satellite launch window and data acquisition progress. This ensures that satellite data packet loss and abnormal task interruption do not occur during mode switching. The formula for determining the service suspension safety duration is as follows: ,in The "Business Security Suspension Duration" represents the effective duration for which the device can safely suspend regular business operations and is used for configuration mode listening. This represents the remaining time of the current satellite mission launch cycle. The hardware latency for mode switching and the basic latency for instruction response are fixed parameters inherent to the device. If calculated... If the value is >0, the current moment is considered a safe switching window, allowing a temporary halt to routine data acquisition and satellite launch services; if... This indicates that the equipment is about to enter the satellite launch window. Priority will be given to the main satellite launch service, and the switch to remote configuration mode will be postponed to avoid the failure of main service data loss.

[0051] S2033: Working mode switching: Under the condition of meeting the safety switching conditions, DCP actively suspends the local data acquisition timer and satellite launch scheduling task, closes the regular business serial port data reporting logic, exits the regular operation mode, and switches to the dedicated remote configuration mode.

[0052] S2034: Serial port listening parameter configuration: The DCP main control unit reconstructs the working state of the service data serial port, initializes the serial port baud rate, parity bit, data bits, and stop bits, enables the serial port continuous receive interrupt, clears the serial port receive buffer, and eliminates the interference of historical residual frame data on instruction parsing.

[0053] S2035: Continuous Listening and Standby: In remote configuration mode, the DCP continuously listens to the service data serial port with high priority, captures external downlink command frames in real time, maintains a standby interactive state, and waits for status query commands or parameter configuration commands issued by the remote monitoring center to complete the preparatory work.

[0054] Compared with existing technologies, the beneficial effects of this invention are:

[0055] 1. This application adopts a dual-mode remote control solution of out-of-band serial port pass-through and IO activation serial port multiplexing, which completely eliminates the traditional DCP equipment operation and maintenance mode that relies on professional personnel and dedicated cables for on-site debugging. It can realize remote status query, fault diagnosis and dynamic parameter update for DCP terminals deployed in the field. There is no need for personnel to go to remote field sites such as mountains, waters and deserts, which greatly reduces the operation and maintenance costs of manpower, material resources and time, and solves the problem of huge operation and maintenance costs caused by the dispersed deployment and remote geographical location of traditional technical equipment.

[0056] 2. By adjusting the core parameters of the DCP transmission channel, transmission time interval, and data acquisition cycle in real time, dynamically, and at the second level according to the field channel interference status, satellite overhead timing changes, and emergency mission requirements of extreme weather and geological disasters, no on-site manual operation is required. It can quickly adapt to sudden monitoring scenarios, effectively avoid the defects of monitoring data interruption, parameter adaptation lag, and insufficient acquisition accuracy under extreme conditions, and significantly improve the emergency operation capability and data reliability of the space-ground integrated meteorological monitoring network.

[0057] 3. By setting up two complementary technical solutions, a 4G DTU transparent transmission out-of-band management solution is adopted for new devices with independent debugging serial ports, and an IO activation serial port multiplexing solution is adopted for old low-cost devices without debugging serial ports or only single service serial ports. The two solutions work together to fully cover all models of DCP devices in the market, solving the industry pain points that traditional transformation solutions cannot be adapted to old single serial port devices and that it is difficult to upgrade existing terminals to be intelligent. The device adaptability and scenario coverage are extremely high.

[0058] 4. Hardware modification is completed only through external communication modules, IO activation lines and analog switches. There is no need to replace the main hardware of the DCP device, nor to tamper with or intrude into the core firmware of the device. The original satellite data acquisition and transmission business logic of the device is completely preserved. At the same time, through the mode switching security judgment mechanism and data validity verification mechanism, the parameter configuration process is prevented from preempting and interfering with the main satellite business. This solves the problems of high modification cost, poor compatibility, easy damage to the original business and poor operation stability of traditional modification solutions.

[0059] This invention employs a dual-path remote management and control scheme that can be deployed independently or in combination. Addressing the shortcomings of traditional DCP equipment, such as high maintenance costs, slow emergency response, poor compatibility with older equipment, and potential interference with main services during upgrades, this invention utilizes non-intrusive, lightweight upgrades to ensure compatibility with various existing equipment, enabling remote monitoring and dynamic parameter adjustment of DCP equipment. Combined with data verification, secure switching, and parameter adaptive algorithms, it adapts to complex outdoor channel environments and meteorological emergency scenarios, effectively ensuring the stability of satellite data acquisition and transmission services, significantly reducing field maintenance costs, shortening fault and parameter adjustment response times, and substantially improving the operational stability and emergency monitoring capabilities of the meteorological monitoring network.

[0063] Example 1

[0064] Reference Figure 1 This embodiment proposes a remote monitoring and parameter adjustment method for a meteorological satellite data collection platform. For DCP devices with independent external debugging serial ports, a remote communication module is connected to the external debugging serial port of the DCP device. The remote communication module uses a 4G DTU device to establish a bidirectional transparent transmission channel between the remote monitoring center and the DCP debugging serial port via a 4G network. Relying on this transparent transmission channel, remote querying and monitoring of the DCP device's operating status, as well as remote configuration and modification of parameters such as the DCP transmission channel, start transmission time, transmission time interval, and data acquisition cycle, are achieved.

It is physically isolated and logically independent from the service data serial port of the satellite transmitter connected to the DCP device. The 4G DTU device works in pure transparent transmission mode throughout the process.

[0071] The remote parameter allocation process includes a satellite channel quality assessment mechanism, which determines the channel communication status through a comprehensive channel quality coefficient. The corresponding calculation formula is as follows: ;

[0072] in The channel overall quality coefficient, Real-time satellite signal strength for DCP equipment. The current ambient background noise intensity, The preset channel data packet loss rate is set to a value range of [0,1], and the preset channel quality threshold is also set. ,when When interference is detected in the channel, the remote monitoring center automatically triggers the DCP transmission channel and transmission interval parameter adjustment command.

[0073] S105: Result Verification Feedback: After the DCP device completes the parameter update, it sends the latest configuration parameters and execution results back to the remote monitoring center to complete the parameter verification and filing.

[0074] In this implementation scheme, the specific logical steps of S103 are as follows:

[0083] Example 2

[0084] Reference Figure 2This embodiment proposes a remote monitoring and parameter adjustment method for a meteorological satellite data collection platform. For DCP devices that do not have an independent external debugging serial port and are only configured with a single business data serial port, an external circuit including an IO activation line and a serial port multiplexing line is built. The remote monitoring center issues an activation command to wake up the DCP device, enabling the DCP device to switch to remote configuration mode and listen to the business data serial port. By reusing the DCP's unique business data serial port, remote monitoring of device status and dynamic adjustment of working parameters are completed.

[0085] The external circuitry includes a remote communication module and an IO activation signal line. The remote communication module has a built-in controllable GPIO pin, which is connected to the external interrupt wake-up pin of the DCP main control chip through the IO activation signal line. The communication serial port of the remote communication module is connected to the DCP service data serial port in parallel through an analog switch.

[0086] The modification instructions for the parameters "transmission channel, start transmission time, and transmission time interval" are transmitted through the same serial communication line connected in parallel with the IO activation signal line.

[0087] It includes the following steps:

[0088] S201: Hardware modification and setup: Complete the wiring adaptation of the remote communication module, IO activation signal line and analog switch to ensure that the IO activation signal is independently controllable and the serial communication line can be seamlessly switched.

[0089] S202: Remote wake-up activation: When the remote monitoring center sends a wake-up command, the GPIO pin of the remote communication module outputs a high-level pulse of preset duration or a continuous high level, triggering an external interrupt of the DCP main control chip;

[0090] The remote wake-up activation process employs adaptive pulse duration control, and its calculation formula is as follows: ;

[0091] in For the effective pulse duration of IO activation, This is the minimum wake-up response time for the DCP main control chip. This is the environmental disturbance compensation coefficient, with a value range of [1.0, 1.5]. Real-time transmission latency for 4G communication links;

[0092] S203: Mode Switching Listening: After the DCP device detects the activation interrupt signal, it suspends regular data acquisition and satellite launch services, automatically switches to remote configuration mode, and continuously listens for communication data on the service data serial port;

[0093] After receiving the IO activation signal, the DCP device switches from normal operation mode or low-power sleep mode to "remote configuration mode". In this mode, the DCP device actively listens to its data serial port and parses the received instructions.

[0094] S204: Parameter Interaction Configuration: The remote monitoring center sends query or configuration commands through the 4G network, which are transmitted to the DCP service data serial port via the remote communication module. The DCP parses and executes the commands to complete the status query or parameter modification and fixation.

[0095] S205: Exit Configuration Mode: After the parameters are configured, the remote monitoring center issues an exit command, or through the device's built-in timeout mechanism, the DCP device automatically exits the configuration mode, releases the IO activation signal, and resumes normal monitoring and satellite data transmission services.

[0096] The built-in timeout mechanism of the device satisfies the following formula for determining the configuration duration: ,in Configure the real-time dwell time for DCP mode. The value is 30 seconds, which is the minimum effective configuration interaction duration. The value is 120s; when > When there is no valid command interaction on the serial port, DCP automatically exits the remote configuration mode.

[0097] In this implementation scheme, the specific logical steps of S203 are as follows:

[0103] In this implementation scheme, the specific logical steps of S204 are as follows:

[0104] S2041: Remote command delivery encapsulation: The remote monitoring center generates corresponding DCP status query commands or parameter configuration commands based on the on-site monitoring conditions, satellite channel quality, and emergency monitoring level. The commands are encapsulated according to the DCP private serial port protocol. The frame structure includes a frame header, device ID, command function code, parameters to be configured, CRC check code, and frame tail. The commands are then delivered to the on-site remote communication module via the 4G wireless network.

[0105] S2042: Communication module transparent forwarding: The remote communication module receives 4G downlink commands, completes the protocol conversion from network data to serial port data, does not parse or tamper with the command content, and forwards the standard serial port commands to the DCP service data serial port that is in the listening state;

[0106] S2043: DCP command validity verification: The DCP main control unit continuously listens to the service serial port data stream. After receiving the serial port command, it first matches the unique device ID and verifies the CRC check code to filter out valid commands for the local machine and filter out broadcast miscellaneous packets, interference garbled characters and invalid commands that are not local machines.

For meteorological emergency level coefficients, conventional steady-state monitoring scenarios For emergency monitoring scenarios involving heavy rain, typhoons, and floods, the value range is (0, 0.5). The higher the emergency level, the larger the value, and the higher the number of data collection and transmission frequencies after parameter updates. The channel transmission reliability coefficient has a value range of [0.8, 1.0]. The lower the channel signal-to-noise ratio, the higher the packet loss rate. The smaller the value, the better it is used to compensate for data loss caused by channel instability;

[0110] S2045: Parameter Firmware Storage: DCP writes the calculated and corrected final parameters into the non-volatile Flash memory of the device's main controller, overwriting the original firmware parameters. The device can load the new parameters and run without restarting, thus permanently firming the working parameters.

[0111] S2046: Execution result response feedback: After the parameter configuration is completed, DCP generates a response frame containing a comparison of the old and new parameters, the configuration status code, and the device operating status. This frame is then fed back to the remote communication module via the service serial port and finally uploaded to the remote monitoring center to complete the configuration archiving and verification.
