Description

Technical Field

[0001] This application relates to the field of equipment operation and maintenance technology, specifically to an operation and maintenance management method and related equipment for power supply equipment. Background Technology

[0002] Equipment operation and maintenance (O&M) technologies are moving towards intelligence, integration, and networking. In practice, field monitoring units (FSUs) need to directly connect to numerous heterogeneous intelligent and non-intelligent devices. Due to the wide variety of these heterogeneous devices, which may originate from different manufacturers, there is significant fragmentation in the communication protocols (such as Modbus, CANopen, and proprietary protocols) and communication interfaces (such as RS-485, CAN, and Ethernet). This severely limits the integration capabilities of the O&M system, keeps costs high, and restricts users' choices in field equipment selection and future equipment expansion, leading to significant constraints on equipment selection and monitoring capacity expansion. Summary of the Invention

[0003] In view of the above, this application provides an operation and maintenance management method and related equipment including power supply equipment, which can solve the problem that existing operation and maintenance systems are greatly restricted in equipment selection and expansion.

[0004] In a first aspect, embodiments of this application provide an operation and maintenance management method including a power supply device, applied to a communication conversion device. The communication conversion device is communicatively connected to a field monitoring unit, which in turn is communicatively connected to a monitoring center device based on a preset communication protocol. The communication conversion device is also communicatively connected to multiple first devices, each including a power supply device, and each first device corresponds to one or more communication protocols. The operation and maintenance management method including the power supply device includes: acquiring device data from at least one of the multiple first devices; parsing the device data; and, based on the parsing results, determining the target data to be converted and the corresponding processing based on the target data. The processing levels correspond to different protocol mapping rules and / or different data reporting rules, and the data reporting rules define the priority of data reporting. Based on a preset protocol mapping rule library, a first protocol mapping rule corresponding to the processing level is determined. Based on the first protocol mapping rule, the target data is converted into a first data frame conforming to the preset communication protocol. The first protocol mapping rule defines field mapping logic and field encapsulation logic for mapping and encapsulating the fields of the target data into a data frame conforming to the preset communication protocol. Based on the first data reporting rule corresponding to the processing level, the first data frame is sent to the field monitoring unit to be uploaded to the monitoring center equipment.

[0005] The above technical solution uses the communication conversion device as a universal adaptation layer between the FSU and multiple first devices. The communication conversion device is responsible for data acquisition and protocol conversion processing, and then sends the processed data frames conforming to the preset communication protocol to the FSU through the uplink interface. From the FSU's perspective, the communication conversion device can be considered a regular data source conforming to the preset communication protocol. The FSU does not need to be aware of the complexity of the field devices connected to the communication conversion device, making the selection of FSUs diverse and achieving the goal of "unified upper-layer standards and open access to lower-layer devices." Users can freely choose the end-user field devices without relying on the FSU manufacturer's hardware and software customization, achieving decoupling between field devices and the FSU, simplifying the design of the operation and maintenance system, and reducing system integration, maintenance, and upgrades. The FSU reduces costs, and because it only needs to handle a single, standard, preset communication protocol, its hardware and software complexity is greatly reduced, allowing it to focus on core monitoring logic and improving FSU reliability. When there is a need to connect new field devices, only hardware and software updates are required during the testing of the communication conversion equipment, greatly shortening the deployment and expansion cycle and improving the flexibility and response speed of the operation and maintenance system. Furthermore, by dividing data into different processing levels, with different processing levels corresponding to different protocol mapping rules and / or different data reporting rules, different levels of data have different communication priorities and frame encapsulation logic. High-level data is processed first and fully encapsulated to avoid information loss and ensure the real-time reporting of high-level data, while low-level data is encapsulated in a simplified manner, saving bus bandwidth and device hardware resources.

[0006] In some embodiments, the device data includes a status word indicating a device operating mode, and the method further includes: constructing a state machine corresponding to the at least one first device; switching the state of the state machine based on the status word in the parsing result so that the state of the state machine matches the device operating mode indicated by the status word; and adjusting the processing level corresponding to the target data based on the state of the state machine.

[0007] In some embodiments, the priority of the data reporting includes a first priority and a second priority, wherein the first priority is higher than the second priority, the priority corresponding to the first data frame is the second priority, and the step of sending the first data frame to the field monitoring unit includes: in the timing control stage of sending the first data frame to the field monitoring unit, if a data frame with the first priority to be sent is detected, the timing control stage is interrupted to execute sending the data frame with the first priority to the field monitoring unit.

[0008] In some embodiments, obtaining device data of at least one of the plurality of first devices includes: obtaining the device data reported by the at least one first device when a preset trigger condition is met; and / or polling each of the plurality of first devices at a preset period based on a preset downlink protocol to obtain the device data of the at least one first device, wherein the preset downlink protocol records interface information and device data storage information of each first device; and converting the target data into a first data frame conforming to the preset communication protocol based on the first protocol mapping rule includes: performing engineering value conversion and filtering on the target data; and converting the filtered target data into a first data frame conforming to the preset communication protocol based on the first protocol mapping rule.

[0009] In some embodiments, the method further includes: receiving a control command forwarded by a field monitoring unit from a monitoring center device; parsing the control command to determine a target first device corresponding to the control command, wherein the target first device is one or more of the plurality of first devices; converting the control command into an executable command for the target first device based on a preset command mapping rule; and sending the executable command to the target first device.

[0010] In some embodiments, the method further includes: receiving execution result information of the executable instruction reported by the target first device; determining a second protocol mapping rule corresponding to the execution result information based on the preset protocol mapping rule base and the processing level corresponding to the execution result information; converting the execution result information into a second data frame conforming to the preset communication protocol based on the second protocol mapping rule; determining a second data reporting rule corresponding to the execution result information based on the processing level corresponding to the execution result information; and sending the second data frame to the field monitoring unit based on the second data reporting rule to upload it to the monitoring center device.

[0011] In some embodiments, the preset communication protocol includes the Tower Protocol. Before acquiring the device data of at least one of the plurality of first devices, the method further includes: initializing the communication conversion device based on a preset configuration file. The preset configuration file includes information of the plurality of first devices and a preset protocol mapping rule library. The protocol mapping rules in the preset protocol mapping rule library define field mapping logic and field encapsulation logic for mapping and encapsulating fields of target data in the device data into data frames conforming to the Tower Protocol.

[0012] Secondly, this application also provides an equipment operation and maintenance system, including: a plurality of first devices, including a power supply device; a monitoring center device; a field monitoring unit, wherein the field monitoring unit is communicatively connected to the monitoring center device based on a preset communication protocol; and a communication conversion device, which is communicatively connected to the field monitoring unit and the plurality of first devices respectively, wherein the communication conversion device is used to execute the above-mentioned operation and maintenance management method including the power supply device.

[0013] Thirdly, this application also provides a communication conversion device, which includes a processor and a memory. The memory is used to store instructions, and the processor is used to call the instructions in the memory to enable the communication conversion device to execute the above-mentioned operation and maintenance management method including power supply equipment.

[0014] Fourthly, embodiments of this application also provide a computer-readable storage medium that stores computer instructions. When the computer instructions are executed on a communication conversion device, the communication conversion device performs the aforementioned operation and maintenance management method including power supply equipment.

[0015] The technical effects brought about by the second to fourth aspects mentioned above can be found in the descriptions of the methods in the above-mentioned method section, and will not be repeated here. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0025] Currently, equipment operation and maintenance (O&M) technologies are moving towards intelligence, integration, and networking. In actual operation, field monitoring units (FSUs) need to directly connect to numerous heterogeneous intelligent and non-intelligent devices. Due to the wide variety of these heterogeneous devices, which may come from different manufacturers, the communication protocols (such as Modbus, CANopen, and proprietary protocols) and communication interfaces (such as RS-485, CAN, and Ethernet interfaces) used in their deployment exhibit severe fragmentation. This results in high complexity and cost for O&M system integration.

[0026] In related technologies, a feasible approach is to use an integrated FSU. This FSU requires integrated hardware with multiple communication interfaces and built-in drivers for various device protocols. It directly connects to end devices through these interfaces. The FSU manufacturer is responsible for developing and updating the communication interfaces and protocols. When users want to connect new devices, they rely on support from the FSU manufacturer, binding them to a single FSU manufacturer's ecosystem and depriving them of autonomy in device selection. Furthermore, when adding or replacing devices not supported by the FSU manufacturer, users must wait for the FSU manufacturer's lengthy driver development, testing, and release cycles, hindering rapid response to on-site needs and resulting in poor system scalability. This leads to significant constraints on device selection and subsequent monitoring and expansion.

[0027] Based on this, this application provides an operation and maintenance management method and device including power supply equipment to solve the problem that existing operation and maintenance systems heavily rely on FSU manufacturer support for equipment selection and subsequent monitoring and expansion.

[0028] The operation and maintenance management method for power supply equipment in this application embodiment can be applied to communication conversion equipment, such as... Figure 1 The communication conversion device shown.

[0029] like Figure 1 As shown, the equipment operation and maintenance system 10 may include a communication conversion device 101, a field monitoring unit (FSU) 102, a monitoring center device 103, and multiple first devices 104.

[0030] The FSU 102 is an embedded intelligent monitoring host deployed at monitoring sites (such as communication base stations, data centers, etc.), serving as a key node connecting field devices (various sensors, intelligent / non-intelligent devices) with the upper-level monitoring center. The FSU 102 can communicate with the upper-level monitoring center through preset standard interfaces and communication protocols. For example, if monitoring center device 103 is a device within the upper-level monitoring center, and the FSU 102 communicates with monitoring center device 103 via a standard tower interface and tower protocol, this can be used as an example. The data reported by the FSU 102 can be uniformly managed, alarm aggregated, operation and maintenance scheduled, stored, and analyzed by monitoring center device 103. Monitoring center device 103 may include servers, network devices, consoles, and display devices deployed within the monitoring center.

[0031] In some embodiments, integrated FSUs can directly interface with various sensors and smart / non-smart devices to perform functions such as data acquisition, protocol parsing, local logic processing, alarm reporting, and remote control execution. However, such FSUs are costly, and each integrated FSU requires a complete set of built-in communication interfaces and protocol processing capabilities. For different maintenance sites, the field devices may differ and change, and only a small portion of the communication interfaces and protocol processing capabilities may be used, resulting in redundancy of hardware and software resources. The FSU 102 in this embodiment can be any FSU conforming to a preset communication protocol (e.g., tower protocol), without the need for direct interface capabilities with various field devices. FSU 102 can handle only a single, standard communication protocol, significantly reducing hardware and software complexity. FSU 102 can focus on core monitoring logic, improving reliability.

[0032] The communication conversion device 101 is communicatively connected to the FSU 102 and multiple first devices 104. The multiple first devices 104 can refer to field devices deployed at the monitoring site, and can include various sensors, intelligent devices, and non-intelligent devices. For example, the multiple first devices 104 can include power supply equipment, air conditioners, batteries, temperature and humidity sensors, smoke sensors, access control devices, etc. The multiple first devices 104 can correspond to multiple communication protocols and multiple communication interfaces. This application embodiment does not limit the communication protocol and communication interface used by each first device 104. For example, the communication conversion device 101 includes an uplink interface and multiple downlink interfaces. The uplink interface is used for communication connection with the FSU 102, and the multiple downlink interfaces are used for communication connection with the multiple first devices 104. One downlink interface can correspond to one first device 104.

[0033] The communication conversion device 101 serves as a universal adaptation layer between the FSU 102 and multiple first devices 104. The communication conversion device 101 is responsible for data acquisition and protocol conversion processing, sending the processed data to the FSU 102 via the uplink interface. For the FSU 102, the communication conversion device 101 is treated as a regular data source conforming to a preset communication protocol. The FSU 102 does not need to be aware of the complexity of the field devices connected to the communication conversion device 101. By introducing the communication conversion device 101, the goal of "unified upper-layer standards and open access for lower-layer devices" can be achieved.

[0034] For example, the communication conversion device 101 can acquire device data from at least one of the multiple first devices 104, parse the device data, and determine the target data to be converted based on the parsing results. The communication conversion device 101 can also convert the target data into a first data frame conforming to a preset communication protocol (e.g., the tower protocol) based on a preset protocol mapping rule base, and send the first data frame to the FSU 102, which then uploads the first data frame to the monitoring center device 103, thereby enabling the device data of the first device 104 to be uploaded to the monitoring center device 103.

[0035] In some embodiments, the communication conversion device 101 may include multiple communication interfaces and device drivers to communicate with each of the first devices 104. The communication conversion device 101 may also have the capability to standardize the conversion of multiple communication protocols to a preset communication protocol (e.g., the tower protocol) to convert device data into a first data frame conforming to the preset communication protocol. For example, the communication conversion device 101 communicates with sensors within the maintenance site via an RS485 interface, and the data exchange communication protocol may be the Modbus protocol. Another example is that the communication conversion device 101 communicates with photovoltaic systems, battery clusters, etc., within the maintenance site via a CAN interface, and the data exchange communication protocol may be the CANopen protocol. Yet another example is that the communication conversion device 101 communicates with video surveillance cameras, air conditioning systems, etc., within the maintenance site via an Ethernet interface, and the data exchange communication protocol may be the HTTP protocol or the Modbus TCP protocol, etc.

[0036] In some embodiments, the communication conversion device 101 may also have the function of converting and sending control commands, so that the control commands (the control commands originate from the monitoring center device 103) issued by the FSU 102 in accordance with the preset communication protocol can be converted into executable commands of the first device 104 and sent out, so that the control commands issued by the monitoring center device 103 can control the first device 104.

[0037] In some embodiments, since the communication conversion device 101 can be maintained by the user, the user can update the communication interface and device driver of the communication conversion device 101 according to the actual equipment monitoring and maintenance needs, which facilitates equipment selection and monitoring expansion.

[0038] The communication conversion device 101 may include a chip with data processing / control functions. For example, the communication conversion device 101 may include a processor, a microprogrammed control unit (MCU), a programmable logic controller (PLC), a digital signal processor (DSP), etc.

[0039] In some embodiments, the communication conversion device 101 can support local configuration, centralized configuration via a remote cloud platform, or near-field configuration via a mobile phone / tablet APP. For example, a mobile phone can connect to the communication conversion device 101 via NFC, Bluetooth, or other means to configure the communication conversion device 101. The configuration may include updating the device driver, protocol mapping rule base, etc. The protocol mapping rule base may include one or more protocol mapping rules.

[0040] It is understood that the communication conversion device 101 of this application can be used not only for environmental monitoring of communication base stations (multiple first devices may include power equipment using different interfaces and protocols - switching power supplies / battery packs / generators, etc., environmental equipment - air conditioners / various sensors / access control, etc., main equipment - BBU / 5G / 4G main equipment, etc.), operation and maintenance monitoring of data center infrastructure (multiple first devices may include uninterruptible power supplies, precision air conditioners, distribution cabinets, generators, deployed sensors, etc. connected to the data center from different brands), and operation and maintenance monitoring of smart photovoltaic power stations (multiple first devices may include various photovoltaic inverters, combiner boxes, meters, deployed sensors, etc.). The communication conversion device 101 can also be applied to the field of industrial internet, for example, in factory workshops, converting data from old industrial equipment (using PLC proprietary protocols) into standard OPC UA or MQTT protocols and uploading it to the industrial internet platform; in the field of building automation system upgrades, for example, without replacing the original building automation host, using the communication conversion device 101 to connect old and new energy-saving equipment / IoT sensors, and then uploading them to the building monitoring center through standard protocols.

[0041] Figure 2 This is a flowchart illustrating the steps of an embodiment of the operation and maintenance management method for power supply equipment provided in this application. The operation and maintenance management method for power supply equipment can be applied to the aforementioned communication conversion equipment. Depending on different needs... Figure 2 The order of steps in the flowchart shown can be changed, and some steps can be omitted or combined.

[0042] The operation and maintenance management method for power supply equipment may include the following steps: Step S201: Obtain device data of at least one of the multiple first devices.

[0043] In some embodiments, device data may include one or more of telemetry data, remote signaling data, remote control feedback data, and fault and event log data. For example, telemetry data may refer to continuously changing, numerical operating data, which can be monitored by sensors or fed back by field devices, including but not limited to voltage, current, power, temperature, humidity, smoke concentration, air conditioning set temperature, and return air temperature. Remote signaling data may refer to status data with "normal / alarm" or "on / off" states, including but not limited to smoke alarms, water immersion alarms, door sensor status, and communication interruptions. Remote control feedback data may refer to the results returned by the field device after performing remote control, including but not limited to successful / failed remote power-on, successful / failed remote power-off, device mode switching results, and device parameter configuration results. Fault and event log data may be information actively reported by the field device, including but not limited to device self-test result data and device alarm data.

[0044] In some embodiments, the device data collection modes include, but are not limited to, master-slave polling, event-triggered (such as device active reporting), and hybrid (polling + subscription).

[0045] For example, acquiring device data from at least one of a plurality of first devices may specifically include: acquiring device data reported by at least one first device when a preset trigger condition is met; and / or polling each of the plurality of first devices at a preset period based on a preset downlink protocol to acquire device data from at least one first device. The preset downlink protocol may record interface information and device data storage information for each first device, thereby enabling the communication conversion device to collect device data through a polling method. For example, based on the communication interfaces of the plurality of first devices, the registers of the plurality of first devices can be accessed to read the device data of the plurality of first devices.

[0046] In some embodiments, the preset period can be set according to actual monitoring needs, and this application embodiment does not limit this. For example, the preset period is every 5 minutes. The preset trigger condition can also be set according to actual needs, and this application embodiment does not limit this. For example, the preset trigger condition can be set based on the active reporting needs of field devices (such as active alarm reporting or active reporting of specific data / status).

[0047] It is understood that the communication conversion device has completed initialization configuration before executing step S201, thereby enabling the communication conversion device to smoothly execute the operation and maintenance management method including power supply equipment according to the embodiments of this application. For example, after the communication conversion device is powered on, it can be initialized and configured through a network server, a serial communication interface, or by receiving configuration instructions transmitted from an upper layer based on the tower protocol. That is, the network server can send a preset configuration file to the communication conversion device through the network, or an external device can import the preset configuration file to the communication conversion device through a serial communication interface (such as UART, RS-232, RS-485, etc.), or an external device can send a preset configuration file to the communication conversion device based on the tower protocol.

[0048] It is understood that if the communication conversion device has not completed its initialization configuration before executing step S201, it can be initialized based on a preset configuration file. The preset configuration file may include communication-related information of the multiple first devices (e.g., communication-related information includes, but is not limited to, device type, physical address, communication parameters, etc.) and a preset protocol mapping rule base. The communication-related information of the multiple first devices can be used to configure multiple downlink interfaces, enabling the communication conversion device to interact with multiple first devices. For example, the communication conversion device can establish a communication connection with a first device to receive the preset configuration file sent by the first device. The first device can be a portable device such as a mobile phone or tablet computer that communicates with the communication conversion device in the near field, or it can be a server or other device that communicates remotely with the communication conversion device.

[0049] In some embodiments, initializing the communication conversion device may include configuring the device type, physical address, communication parameters, and protocol mapping rules for each downlink interface. Communication parameters may be configuration parameters used to establish a communication connection between the communication conversion device and the downlink device (field device) and ensure normal data interaction. Protocol mapping rules may define field mapping logic and field encapsulation logic to encapsulate target data into data frames conforming to a preset communication protocol. For example, the field mapping logic defines the correspondence between "raw data" and "protocol-defined fields," and the field encapsulation logic defines how to package the mapped field data into a transmittable data frame according to the format specified by the preset communication protocol. For another example, for target data in the Modbus protocol, the field mapping logic defines the logic for mapping the first data field of the target data to the second data field in the data frame of the preset communication protocol, and the field encapsulation logic defines how to encapsulate the field mapping result (such as the mapping result of the first data field) according to the frame structure of the preset communication protocol.

[0050] In some embodiments, the protocol mapping rules can be in the form of a protocol mapping table, a static configuration file, a pluggable driver plugin, or can be dynamically generated by a script engine.

[0051] Step S202: Parse the device data, and based on the parsing results, determine the target data to be converted and the corresponding processing level of the target data. Different processing levels correspond to different protocol mapping rules and / or different data reporting rules. The data reporting rules define the priority of data reporting.

[0052] In some embodiments, different device data may have different processing levels, and different processing levels may correspond to different protocol mapping rules and / or different data reporting rules. During the initial configuration of the communication conversion device, the data reported by the first device can be divided into multiple processing levels. Taking the device data reported by the first device as including three types—alarm data, operational data, and statistical data—as an example, each type corresponds to a different level. For instance, alarm data corresponds to Level 1 (highest level), operational data corresponds to Level 2, and statistical data corresponds to Level 3 (lowest level). The protocol mapping rule corresponding to Level 1 data (such as alarm data for overcurrent, overvoltage, power failure, and battery thermal runaway) can be to use complete field encapsulation (i.e., retaining all fields and strictly prohibiting compression or discarding). The corresponding data reporting rule can be to allocate the highest transmission priority and dedicated priority transmission time slot at the data link layer to achieve immediate reporting, and configure a multiple retransmission mechanism to allow it to exclusively occupy link resources during transmission. For Level 2 data (such as sampling data during equipment operation: voltage and current sampling data), the corresponding protocol mapping rule can be simplified field mapping (appropriate simplification, elimination of secondary and unnecessary fields, and complete retention of core fields), and the corresponding data reporting rule can be reporting at a preset period. For Level 3 data (such as historical power consumption statistics of equipment, equipment asset tags, and software version numbers), the corresponding protocol mapping rule can be to trim redundant fields (retaining only key and necessary fields) and perform message bit padding, etc. The corresponding data reporting rule can be to use a buffer to merge multiple Level 3 data into batch data packets, and perform low-priority intermittent transmission of batch data packets when the network is idle, so as to save hardware computing power and bus bandwidth.

[0053] In some embodiments, the acquired device data may contain valid data, redundant data, invalid data, etc. By parsing and processing the device data, and filtering out valid target data from the original device data based on the parsing results, subsequent transformation and standardization of the target data can be performed, thereby improving data processing efficiency and preventing invalid data from interfering with subsequent business logic. The rules for filtering target data can be predetermined based on on-site monitoring business requirements, protocol format requirements, data types, monitoring point information, and data validity conditions. Taking filtering based on protocol format requirements as an example, determining the target data to be transformed based on the device data parsing results may include: determining the target data to be transformed in the parsing results based on protocol mapping rules corresponding to the processing level, so that the filtered target data can be subsequently transformed and encapsulated into a first data frame conforming to a preset communication protocol.

[0054] In some embodiments, the parsing and processing of device data may include one or more of the following: data validity verification, data field splitting and extraction (splitting valid data fields from the original device data), and data type identification (identifying the device data as telemetry, remote signaling, remote control feedback, etc.).

[0055] In some embodiments, after determining the target data to be converted, the target data can be subjected to engineering value conversion and filtering. Engineering value conversion refers to converting the raw values ​​collected by sensors / devices (such as ADC sample values, voltage values) into values ​​with practical engineering significance (such as temperature, pressure, concentration, etc.) using a preset physical formula. Filtering can be used to remove noise (random fluctuations) from the engineering values ​​to obtain smooth and reliable target data. For example, filtering can be implemented using moving average filtering, median filtering, first-order low-pass filtering, etc.

[0056] In some embodiments, the device data may further include a status word indicating the device's operating mode. The communication conversion device may also adjust the processing level corresponding to the target data by: constructing a working condition state machine corresponding to at least one first device; switching the state of the working condition state machine based on the status word in the parsing result so that the state of the working condition state machine matches the device operating mode indicated by the status word; and adjusting the processing level corresponding to the target data based on the state of the working condition state machine so that the target data may have different processing levels under different device operating conditions, thereby realizing dynamic working condition adaptation of the data processing level.

[0057] Taking the first device as a power supply as an example, a state machine corresponding to the power supply's operating conditions can be built inside the communication conversion equipment. These operating conditions can include: normal mains power float charging, mains power outage discharge, battery equalization charging maintenance, and high-risk thermal runaway conditions. When parsing device data, the communication conversion equipment extracts the status words from the device data in real time to drive the state machine to switch between operating conditions. The communication conversion equipment can adjust the processing level according to the current operating condition of the power supply, such as changing the truncation accuracy of fields like voltage, current, and individual cell temperature, the engineering value conversion factor, and the reporting priority.

[0058] The communication conversion equipment can also be linked with maintenance work orders. For example, the communication conversion equipment receives maintenance work order information injected by the monitoring center equipment through the uplink interface. When the maintenance work order information indicates "on-site emergency repair status", the communication conversion equipment can remove restrictive reporting conditions such as the daily polling cycle, and fully encapsulate and report the equipment data (such as single cell internal resistance, single cell voltage, high-frequency ripple voltage, and other maintenance fields) at high frequency. When the maintenance work order information indicates "routine maintenance and repair", the communication conversion equipment can start a reverse interception lock-up mechanism at the protocol encapsulation layer. At this time, even if the on-site monitoring unit forwards downlink control commands from the monitoring center equipment (such as remote power on / off, modification of protection thresholds, and issuance of equalization charge test commands), the communication conversion equipment can intercept the commands and send them to the lower-level equipment, thereby preventing base station miscontrol accidents caused by misoperation on the monitoring center side from the bottom-level communication layer.

[0059] Step S203: Based on the preset protocol mapping rule library, determine the first protocol mapping rule corresponding to the processing level.

[0060] In some embodiments, the preset protocol mapping rule base may include a variety of protocol mapping rules. After determining the processing level corresponding to the target data, the protocol mapping rule corresponding to the processing level can be determined from the preset protocol mapping rule base (referred to as the first protocol mapping rule in this application embodiment).

[0061] Step S204: Based on the first protocol mapping rule, the target data is converted into a first data frame that conforms to the preset communication protocol. The first protocol mapping rule defines field mapping logic and field encapsulation logic that map and encapsulate the fields of the target data into a data frame that conforms to the preset communication protocol.

[0062] In some embodiments, the communication conversion device may map and convert the fields of target data into a first data frame conforming to a preset communication protocol based on a first protocol mapping rule. For example, the target data may be mapped and encapsulated into a data frame conforming to the preset communication protocol according to the data frame structure, data encoding rules, and communication rules defined by the preset communication protocol.

[0063] In some embodiments, converting target data into a first data frame conforming to a preset communication protocol may refer to converting the target data after conversion and filtering into a first data frame conforming to a preset communication protocol.

[0064] Step S205: Based on the first data reporting rule corresponding to the processing level, the first data frame is sent to the field monitoring unit to be uploaded to the monitoring center equipment.

[0065] In some embodiments, the data reporting rule corresponding to the first data frame (referred to as the first data reporting rule in this application embodiment) can be determined based on a pre-defined mapping relationship between processing levels and data reporting rules. After converting to obtain a first data frame that conforms to a preset communication protocol, the communication conversion device can send the first data frame to the field monitoring unit (FSU) based on the first data reporting rule. The FSU then uploads the first data frame to the monitoring center device, thereby enabling device data to be uploaded to the monitoring center device via the uplink.

[0066] In some embodiments, taking the data reporting priority as including a first priority, a second priority, and a third priority as an example, where the first priority is higher than the second priority, and the second priority is higher than the third priority, assuming the priority corresponding to the first data frame is the second priority or the third priority, sending the first data frame to the field monitoring unit may further include: in the timing control stage of sending the first data frame to the field monitoring unit, if a data frame of the first priority to be sent is detected, the timing control stage is interrupted to execute sending the data frame of the first priority to the field monitoring unit. That is, in the timing control stage of uploading non-first priority data frames to the field monitoring unit in this embodiment, once the communication conversion device detects a data frame of the first priority to be reported, its internal hard interrupt program will immediately suspend, truncate, or temporarily terminate the currently ongoing transmission queues of second-level data (second priority) and third-level data (third priority), clear and exclusively occupy the uplink physical channel, ensuring that first-level data is uploaded with priority in a zero-latency, non-preemptive manner.

[0067] Compared with the prior art, the embodiments of this application have at least the following advantages: In this embodiment, a communication conversion device serves as a universal adaptation layer between the FSU and multiple first devices. The communication conversion device is responsible for data acquisition and protocol conversion processing, and then sends the processed data frames conforming to a preset communication protocol to the FSU via an uplink interface. For the FSU, the communication conversion device can be considered a regular data source conforming to the preset communication protocol. The FSU does not need to be aware of the complexity of the field devices connected to the communication conversion device, enabling diverse FSU selection and achieving the goal of "unified upper-layer standards and open lower-layer device access." Users can freely choose the end-user field devices without relying on the FSU manufacturer's hardware and software customization, thus decoupling the field devices from the FSU, simplifying the operation and maintenance system design, and reducing system integration, maintenance, and upgrade costs. Furthermore, since the FSU only needs to handle a single, standard, preset communication protocol, its hardware and software complexity is greatly reduced, allowing it to focus on core monitoring logic and improving FSU reliability. When there is a need to connect new field devices, only hardware and software updates are required during the communication conversion equipment test, greatly shortening the deployment and expansion cycle and improving the flexibility and response speed of the operation and maintenance system. Moreover, by dividing data into different processing levels, with different processing levels corresponding to different protocol mapping rules and / or different data reporting rules, different levels of data have different communication priorities and frame encapsulation logic. High-level data is processed first and fully encapsulated to avoid information loss and ensure the real-time reporting of high-level data, while low-level data is encapsulated in a simplified manner, saving bus bandwidth and device hardware resources.

[0068] Figure 3 This is a flowchart illustrating the steps of an embodiment of the operation and maintenance management method for power supply equipment provided in this application. The operation and maintenance management method for power supply equipment can be applied to the aforementioned communication conversion equipment. Depending on different needs... Figure 3 The order of steps in the flowchart shown can be changed, and some steps can be omitted or combined.

[0069] The operation and maintenance management method for power supply equipment may include the following steps: Step S301: Receive control commands from the monitoring center equipment forwarded by the field monitoring unit.

[0070] In some embodiments, the monitoring center equipment also needs to send control commands to field devices to control them. Taking the tower protocol as the preset communication protocol as an example, the control commands sent by the monitoring center equipment can be transmitted to the field monitoring unit (FSU) based on the tower protocol, and the FSU will forward the control commands to the communication conversion device. For example, the control command can carry the address of the communication conversion device, so that the FSU can forward the control command to the monitoring center equipment after receiving it. That is, the address of the communication conversion device can be pre-recorded in both the monitoring center equipment and the FSU, and the address can be a network address, device address, etc.

[0071] Step S302: Parse the control command and determine the target first device corresponding to the control command. The target first device is one or more devices among a plurality of first devices.

[0072] In some embodiments, the control command may also record relevant information about the target field device (target first device). The communication conversion device can determine the target first device corresponding to the control command by parsing the control command, that is, determine the execution object of the control command. The control command may carry the identification information of the target first device. The communication conversion device can obtain the identification information of the target first device by parsing the control command, and thus determine the target first device corresponding to the control command.

[0073] In some embodiments, the target first device may be one or more of a plurality of first devices, that is, the monitoring center device can control one or more first devices by issuing a control command.

[0074] Step S303: Based on the preset instruction mapping rules, the control instructions are converted into executable instructions for the target first device.

[0075] In some embodiments, since the control commands issued by the monitoring center device are based on a preset communication protocol and contain a lot of information, the control commands can be simplified (for example, the address of the communication conversion device can be removed), retaining the control information related to the control of the field device, and then converting the control information into executable commands that the field device can recognize.

[0076] In some embodiments, the communication conversion device may pre-store preset instruction mapping rules. These rules may record the instruction formats executable by each first device and the conversion rules for converting them into those formats, thereby enabling the conversion of control instructions of a uniform format into instructions executable by each first device. The instruction mapping rules may also record exception handling rules to prevent system anomalies caused by instruction conversion failures.

[0077] For example, the issued control command is to configure a first parameter value for a specified parameter of the target first device. By parsing the control command, it can be determined that the control command is applied to the target first device, and the control information in the control command is to configure the first parameter value for a specified parameter of the target first device. Then, based on the preset command mapping rules, "configure the first parameter value for a specified parameter" is converted into an executable command for the target first device. Subsequently, the target first device can respond to the executable command and configure the specified parameter according to the first parameter value.

[0078] Step S304: The executable instructions are sent to the target first device.

[0079] In some embodiments, after converting to obtain executable instructions, the communication conversion device can send the executable instructions to the target first device for execution through the corresponding downlink interface.

[0080] In some embodiments, step S301 may be executed after step S204 or before step S201, and the embodiments of this application do not limit this.

[0081] The embodiments of this application can realize the conversion and issuance of control commands, enabling the monitoring center to control the field equipment.

[0082] In some embodiments, such as Figure 4 As shown, after executing the instruction, the target device can also report the instruction execution result. For example, the target device can report the instruction execution result to the monitoring center device through a communication conversion device. This operation and maintenance management method including power supply equipment may also include the following steps: Step S305: Receive the execution result information of the executable instructions reported by the target first device.

[0083] In some embodiments, the communication conversion device may receive execution result information of executable instructions reported by the target first device.

[0084] Step S306: Based on the preset protocol mapping rule library and the processing level corresponding to the execution result information, determine the second protocol mapping rule corresponding to the execution result information, and convert the execution result information into a second data frame that conforms to the preset communication protocol based on the second protocol mapping rule.

[0085] In some embodiments, different execution result information may have different processing levels, and different processing levels may correspond to different protocol mapping rules and / or different data reporting rules. During the initial configuration phase of the communication conversion device, the execution result information can be divided into multiple processing levels. Based on the processing level corresponding to the execution result information, the protocol mapping rule corresponding to the execution result information (referred to as the second protocol mapping rule in this embodiment) can be searched in the protocol mapping rule base.

[0086] In some embodiments, in order for the FSU to forward execution result information to the monitoring center device based on a preset communication protocol, the communication conversion device can convert the execution result information into a second data frame conforming to the preset communication protocol based on a second protocol mapping rule. For example, the execution result information is encapsulated into a compliant second data frame according to the data frame structure, data encoding rules, and communication rules defined by the preset communication protocol.

[0087] Step S307: Based on the processing level corresponding to the execution result information, determine the second data reporting rule corresponding to the execution result information.

[0088] In some embodiments, the data reporting rule corresponding to the execution result information (referred to as the second data reporting rule in this application embodiment) can be determined based on a pre-defined mapping relationship between processing level and data reporting rule.

[0089] Step S308: Based on the second data reporting rules, the second data frame is sent to the field monitoring unit to be uploaded to the monitoring center equipment.

[0090] In some embodiments, after encapsulating the execution result information into a compliant second data frame, the communication conversion device can send the second data frame to the FSU based on the second data reporting rules, and the FSU can upload the second data frame to the monitoring center device, so that the monitoring center device can know the execution result of the control command reported by the target first device, which facilitates the subsequent monitoring and management of the target first device.

[0091] In some embodiments, the monitoring center device may also be configured to reissue the control command if it does not receive the execution result information of the executable command reported by the target first device within a preset time. If, after reissuing the control command, the execution result information of the executable command reported by the target first device is still not received within the preset time, the monitoring center may display corresponding warning information, for example, the warning information may be displayed on the display device of the monitoring center. The preset time can be set according to actual needs, and this application embodiment does not limit it in this regard.
