Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a multi-service application program operation and maintenance management method and system based on a low-voltage intelligent circuit breaker. Background Art

[0002] In recent years, circuit breakers (switches) used in low-voltage distribution networks have been developing towards intelligence. Based on the original intelligent switch measurement, communication, and topology identification, the technical route of the fusion terminal has been inherited and further extended to realize the "hardware platformization and software APPization" of low-voltage circuit breakers. However, the APPization of application software business functions also brings the following problems:

[0003] (1) Business apps are highly coupled to each other, and there is a lack of effective supervision on their loading and operation. When adding new apps, they can only be managed manually by users or developers. On the one hand, there are security risks. Once an unknown app is installed privately or by mistake, it may cause abnormal operation or even crash of the smart circuit breaker. On the other hand, due to the mutual coupling between businesses, adding a new app may involve the modification of some existing apps, which leads to insufficient scalability. As the number of business apps increases, management becomes very inconvenient.

[0004] (2) Different business apps need to establish communication with each other to achieve data exchange. As the number of apps increases, the occupation of system resources will increase exponentially. At the same time, due to the lack of unified scheduling, multiple apps are prone to interfere with each other when exchanging data at the same time, resulting in data loss and leakage, and the security of data exchange between apps is difficult to guarantee.

[0005] The operation and maintenance management issues when multiple business APPs coexist on low-voltage intelligent circuit breakers currently rely mainly on manual management by users, which makes it impossible to carry out overall business operation scheduling management and ensure the security and efficiency of data interaction.

[0033] Embodiment 1

[0034] Figure 1This is a flowchart of a method for operation and maintenance management of a multi-service application based on a low-voltage intelligent circuit breaker provided in the first embodiment of the present invention. This embodiment is applicable to the case of operation and maintenance management of a multi-service application of a low-voltage intelligent circuit breaker. The method can be executed by an operation and maintenance management platform, which runs on an operating system, and the operating system is deployed on a low-voltage intelligent circuit breaker. For example, Figure 2 Provided is an architecture diagram of a low-voltage intelligent circuit breaker. An embedded APP comprehensive operation and maintenance management platform 12 is created based on the software operating system 11 of the low-voltage intelligent circuit breaker. The kernel allocates resources and opens interface call permissions to realize function calls and information interaction between the operation and maintenance management platform 12 and the operating system 11. Each application 13 only retains necessary interface call permissions such as peripherals and file systems. The operation and maintenance management platform 12 performs unified authentication and operation management, and provides security for the operating conditions of each APP and data interaction between them. The operation and maintenance management platform 12 can interact with users / superior devices 14 through external interfaces.

[0035] like Figure 1 As shown, the method includes:

[0036] S101: Receive a registration application for a newly added application sent by a smart device, where the registration application includes feature information of the newly added application.

[0037] In this embodiment, the smart device can be any electronic device with data processing capabilities, such as a smart phone, a computer, and a tablet computer. The registration application can be understood as a request for applying to the operation and maintenance management platform for application installation. The characteristic information can be understood as information used to describe the operating information, identification and other characteristics of the application. The application can be an application that performs corresponding business in the low-voltage smart circuit breaker, and the operation and maintenance management platform can manage different business applications.

[0038] When a new application needs to be loaded, the low-voltage intelligent circuit breaker first determines the feature information of the newly added application and establishes a communication connection with the operation and maintenance management platform through the intelligent device. The feature information of the newly added application can be manually input by the user on the intelligent device, or it can be pre-saved in a file and the feature information of the newly added application can be obtained by reading the file through the intelligent device. After determining the feature information of the newly added application, the intelligent device generates a registration application based on the feature information of the application and sends the registration application to the operation and maintenance management platform.

[0039] The operation and maintenance management platform has the function of business APP security loading management, and is responsible for the information authentication, resource allocation and operation management of all business APPs. If a low-voltage intelligent circuit breaker needs to load a new business APP, it is necessary to first establish communication with the operation and maintenance management platform inside the circuit breaker through an intelligent device (for example, a client or a master station). The communication needs to be authenticated by hierarchical permissions, including three permissions: administrator, debugger, and auditor. The administrator has the highest authority and can create new debugger and auditor accounts; the debugger has the authority to read the circuit breaker operation information and modify the equipment setting parameters; the auditor has the authority to read and query the circuit breaker event records and operation logs. The account login passwords are all default values ​​before leaving the factory. After the user's modification takes effect, the operation and maintenance management platform will form a new login whitelist. The registration application can be initiated by any account, and the account that initiates the registration application can also be controlled by setting rights. For example, only the administrator account has the authority to initiate the registration application.

[0040] Optionally, the characteristic information includes at least one of the following: application name, occupied memory resources, and number of threads.

[0041] S102. If the registration application is evaluated to be successful, resources are allocated to the newly added application, and the allocated resource information is fed back to the smart device so that the smart device can obtain the installation package of the newly added application generated by the configuration update based on the resource information. The allocated resources include: system resources and communication channels.

[0042] The registration application is evaluated, and the remaining resources of the operating system in the low-voltage intelligent circuit breaker are judged according to the characteristic information of the newly added application to support the installation of the newly added application. If so, it is determined that the registration application evaluation is passed; otherwise, it is determined that the registration application evaluation is not passed and the application cannot be installed. If the registration application evaluation is passed, resources are allocated to the newly added application, and system resources and communication pipelines are allocated to the newly added application, wherein the system resources can be the starting address and size of the memory space, the application ID code, etc., and the communication pipeline is a channel for completing data transmission. Feedback the allocated resource information to the smart device, and the smart device can obtain the installation package of the newly added application generated by the configuration update based on the resource information. After receiving the allocated resource information, the smart device can update the configuration of the newly added application according to the allocated resource information and generate an installation package, or the smart device sends the resource information to other devices, and the other devices update the configuration of the newly added application according to the resource information and generate an installation package, and then feed the installation package back to the smart device, and install the application to the operating system through the smart device so that the newly added application can be installed normally. For example, if the allocated processor FLASH starting address is 0x08050000 and the size is 64k, the loading domain configuration of the newly added application will be modified accordingly, and so on.

[0043] After the operation and maintenance management platform evaluates and identifies the registration application, if the registration application passes the evaluation, the registration application can be added to the APP registration information list. This list contains the registration time and account for traceability and supports administrator permission to read. After the new APP is updated with the configuration based on the information, dynamic distributed loading can be achieved based on the operating system.

[0044] S103: Receive an installation package of a newly added application sent by the smart device, install the newly added application according to the installation package, and set the state of the newly added application to an isolated running state.

[0045] In this embodiment, the isolated running state can be understood as a running state of an application program, in which the application program cannot exchange information with other applications.

[0046] After the newly added application updates the configuration and generates the installation package, the installation package is sent to the operation and maintenance management platform through the smart device. The operation and maintenance management platform receives the installation package of the newly added application and installs the newly added application based on the installation package of the application. For example, the operation and maintenance management platform can call the system interface to burn and install the newly added application. The application is installed in the operating system. Since the operating system is deployed on the low-voltage intelligent circuit breaker, the application can eventually run on the low-voltage intelligent circuit breaker. After the application is installed, the status of the newly installed application is set to the isolated running state.

[0047] S104. Receive an activation application reported by a newly added application, verify the activation application according to the registration application, and if the verification passes, release the isolated running state of the newly added application, and allocate a pipeline key to the newly added application to perform secure data interaction between applications.

[0048] In this embodiment, the pipeline key can be understood as a key used to encrypt data when the application and the operation and maintenance management platform interact with each other through the communication pipeline.

[0049] The operation and maintenance management platform calls the system interface to monitor the running information of the newly added application, and waits for the application to report the activation application in the allocated communication channel. The newly added application can actively report the activation application, or set the reporting conditions, and generate and report the activation application after the reporting conditions are met. The reporting conditions can be that a certain running information of the application meets certain conditions, or the running time exceeds a certain threshold, etc. The operation and maintenance management platform receives the activation application reported by the newly added application through the communication channel allocated to the newly added application. The activation application can carry relevant information of the application. After receiving the activation application, the operation and maintenance management platform verifies the activation application according to the registration request to determine whether the application is installed according to the registration request. If so, it determines that the verification is passed; otherwise, the verification fails. If the verification is passed, the isolated running state of the newly added application is released, and the newly added application can normally exchange data with other applications through the operation and maintenance management platform. The operation and maintenance management platform allocates pipeline keys to the newly added applications. For example, the pipeline keys are randomly generated and sent to the newly added applications. Alternatively, the operation and maintenance management platform and the newly added applications both pre-store the same key table, which includes the keys and their corresponding identifiers. The operation and maintenance management platform indicates the identifier of the newly added application key, and the newly added application queries the corresponding key from the key table according to the identifier of the key, and uses this key as the pipeline key. When data is exchanged between the application and the operation and maintenance management platform, the data is encrypted according to the pipeline key to ensure data security.

[0050] The embodiment of the present invention provides an operation and maintenance management method for multi-service applications based on a low-voltage intelligent circuit breaker, which solves the problem that multi-service APPs in a low-voltage intelligent circuit breaker cannot be uniformly scheduled and managed. The operation and maintenance management platform uniformly manages the applications. When a new application is added to the low-voltage intelligent circuit breaker, a registration application is sent to the operation and maintenance management platform through an intelligent device. The operation and maintenance management platform evaluates the registration application, and after the evaluation is passed, resources are allocated to install the new application. The installation of the new application is achieved by allocating system resources, and data transmission is achieved by allocating communication pipelines, so as to avoid data interference when multiple applications perform data interaction at the same time, avoid data loss and leakage, and ensure the security of data interaction; after the new application is installed, it is set to an isolated running state, and an activation application reported by the new application is received and after verification is passed, the isolated running state is released. At this time, the application can run normally, and information is exchanged with other applications through the operation and maintenance management platform. To ensure data security, a pipeline key is allocated to the new application, and the application is uniformly managed through the operation and maintenance management platform, which effectively improves the security and efficiency of data interaction.

[0051] Embodiment 2

[0052] Figure 3 This is a flowchart of a multi-service application operation and maintenance management method based on a low-voltage intelligent circuit breaker provided in the second embodiment of the present invention. This embodiment is refined on the basis of the above embodiment. Figure 3 As shown, the method includes:

[0053] S201: Receive a registration application for a newly added application sent by a smart device, where the registration application includes feature information of the newly added application.

[0054] S202. If the registration application is evaluated to be successful, resources are allocated to the newly added application, and the allocated resource information is fed back to the smart device so that the smart device can obtain the installation package of the newly added application generated by the configuration update based on the resource information. The allocated resources include: system resources and communication channels.

[0055] S203: Receive an installation package of a newly added application sent by the smart device, install the newly added application according to the installation package, and set the state of the newly added application to an isolated running state.

[0056] S204: Receive an activation application reported by a newly added application, encrypt the characteristic information in the registration application according to a preset encryption algorithm, and obtain a ciphertext to be verified.

[0057] Optionally, the activation application includes: ciphertext obtained by encrypting characteristic information of the newly added application;

[0058] The newly added application encrypts the characteristic information used for registration to obtain the corresponding ciphertext, and sends the ciphertext as an activation application to the operation and maintenance management platform through the assigned communication channel. When encrypting the characteristic information, a set algorithm can be used for encryption. For example, an irreversible Hash algorithm is used to encrypt the characteristic information into 16-byte data.

[0059] In this embodiment, the ciphertext to be verified can be understood as the ciphertext that needs to be verified. After receiving the activation application, the operation and maintenance management platform uses a preset encryption algorithm to encrypt the characteristic information carried in the registration application. The preset encryption algorithm is consistent with the algorithm used when encrypting the newly added application, and the encryption algorithm can be agreed in advance. By encrypting the characteristic information, the ciphertext to be verified is obtained.

[0060] S205: Determine whether the ciphertext in the activation application is consistent with the ciphertext to be verified. If not, execute S206; if so, execute S207.

[0061] The operation and maintenance management platform compares the ciphertext in the activation application with the ciphertext to be verified to ensure the consistency of the newly added application and the registration information.

[0062] S206: Determine whether the activation application verification has failed.

[0063] If the activation application verification fails, the operation and maintenance management platform will directly kill the newly added application, and the application needs to re-apply for registration. The operation and maintenance management platform can deregister the application in the registration information list.

[0064] S207: Determine whether the activation application verification has passed.

[0065] S208: Release the isolated running state of the newly added application.

[0066] After the activation verification is passed, confirm that the application is installed correctly and release the isolated running state of the newly added application.

[0067] S209. Randomly generate a set number of address numbers, each address number corresponding to one byte of feature information.

[0068] In this embodiment, the set number can be pre-set according to the byte length of the characteristic information. For example, if the byte length of the characteristic information is 16 bytes, the set number is 16. The address number indicates the address where the key information is stored.

[0069] Determine the byte length of the characteristic information, determine the set number according to the byte length; randomly generate the set number of numbers, use the generated numbers as address numbers, and indicate the key storage address through the address numbers, wherein each address number corresponds to one byte of the characteristic information.

[0070] S210. Generate pipeline key information according to each address number, where the pipeline key information is used to indicate the pipeline key.

[0071] In this embodiment, the pipeline key information can be understood as information used to describe the pipeline key, and the pipeline key can be determined by the pipeline key information. The pipeline key information is generated based on each address number, for example, each address number is sorted in sequence, and the obtained value is the pipeline key information.

[0072] The operation and maintenance management platform sends the pipeline key information to the newly added application through the communication pipeline. After receiving the pipeline key information, the newly added application sequentially takes out the corresponding values ​​from the feature information according to the address numbers indicated in the pipeline key information to form the pipeline key.

[0073] After the newly added APP is activated and running, it will receive the pipeline key information automatically created and sent by the operation and maintenance management platform. For example, the pipeline key information is a 16-byte exclusive key address, and each byte represents a randomly generated address number, which corresponds to the byte address of the characteristic information content of the APP. The actual value is taken from the corresponding address to form the final pipeline key exclusive to this application. For example, the address numbers are 01, 05, 08, and 07, respectively, and the corresponding values ​​are taken from address 01, address 05, address 08, and address 07 to form the pipeline key. Since the APP characteristic information is only known to the APP itself and the operation and maintenance management platform, the privacy of the key can be guaranteed. At the same time, in order to take into account both communication security and efficiency, the interactive message of the business APP adopts a symmetric key block encryption algorithm, with a key length of 16 bytes, a block word length of 32 bits, and a number of encryption rounds of 6. Data encryption is achieved through group multi-round mixed bit operations. Each group of pipelines is paired with a unique key to realize the encryption and decryption of interactive messages. The operation and maintenance management platform is responsible for the management of the exclusive keys of each group of pipelines.

[0074] As an optional embodiment, this optional embodiment is further optimized to include steps A1-A4:

[0075] A1. Receive first data to be transmitted sent by the first application through a communication channel between the first application. The first data to be transmitted is generated by the first application according to a set communication protocol format and encrypted according to a channel key corresponding to the first application.

[0076] In this embodiment, the first data to be transmitted can be understood as a type of data that needs to be transmitted, which can be operating data generated during the operation of the application, data interacting with the user during the operation of the application, or data generated by processing the data interacting with the user, and so on. The first application and the second application are applications managed by the operation and maintenance management platform. The first application and the second application first apply for registration on the operation and maintenance management platform, and then they are installed after passing the registration. Then the operation and maintenance management platform assigns them a pipeline key, and the application can transmit and interact data according to the pipeline key. Any application managed by the operation and maintenance management platform can send data as the first application, and can also receive data as the second application.

[0077] The first application generates the first data to be transmitted after the conditions for data transmission are met. For example, the first application obtains data of a set type to determine that the conditions for data transmission are met. After obtaining the data, the first application determines that the data exceeds a certain threshold to determine that the conditions for data transmission are met, and so on. When generating the first data to be transmitted, the first application first determines the data to be transmitted, and then processes the data according to the set communication protocol format to generate data in a specific format. For example, the set communication protocol format defines the format of the data, and the data needs to include a sender and a receiver; the generated data in a specific format is encrypted according to the pipeline key corresponding to the first application to obtain the first data to be transmitted. The first application sends the first data to be transmitted to the operation and maintenance management platform through the communication pipeline between the first application and the operation and maintenance management platform, and the operation and maintenance management platform receives the first data to be transmitted sent by the first application through the communication pipeline between the first application and the first application.

[0078] The first data to be transmitted may include at least one of the following information: a receiving identification code, a sending identification code, a data length, and a data Payload. The Payload is composed of one or more of a control code, data, and a check code.

[0079] A2. Decrypt the first data to be transmitted according to the pipeline key corresponding to the first application, and verify the decrypted first data to be transmitted. If the verification passes, determine the second application as the data recipient.

[0080] Determine the pipeline key corresponding to the first application. The operation and maintenance management platform manages one or more applications, and each application corresponds to a pipeline key. The operation and maintenance management platform can store the pipeline key corresponding to each application in a data table or other form. After receiving the first data to be transmitted sent by the first application, determine the pipeline key corresponding to the first application by querying the data table or other means. Decrypt the first data to be transmitted according to the pipeline key, and verify the decrypted first data to be transmitted. For example, the plaintext data corresponding to the first data to be transmitted includes verification parameters such as a verification code. After decryption, the plaintext data obtained after decryption is verified according to the verification parameters. If the verification passes, determine the data recipient based on the information carried by the decrypted first data to be transmitted, and then determine the data recipient as the second application.

[0081] Illustratively, Table 1 provides a communication protocol format that defines the format of data transmission.

[0082] Table 1

[0083] Frame Header Send identification code Receive identification code Frame number Data length Data Payload Frame end 0x68 1 Byte 1 Byte 1 Byte 2Byte Indefinite length 0x16

[0084] The message is framed with the low byte first and the high byte last. Among them: the sending identification code is the identity code of the message sender APP, and the receiving identification code is the identity code of the message receiver APP, which is assigned by the operation and maintenance management platform when the APP registration is completed. The frame sequence number is used to synchronize the request frame and the response frame, which can improve the communication reliability. It is maintained by the message requester. The frame sequence number used by adjacent frames is self-incrementing, with a minimum value of 1 and a maximum of 0xFF. The data length indicates the length of the payload that follows. The payload consists of a control code, data, and a check code. The control code identifies the data feature and is used by the receiver to identify the purpose of the frame message. The check code is the binary arithmetic sum of all bytes from the first byte of the payload to the check code (excluding overflow values ​​exceeding 256), which is used to identify transmission errors in the data part. The verification of interactive data mainly includes: frame header and frame tail identification judgment, sending and receiving identification code legitimacy judgment, data length verification, verification code calculation and comparison, etc. The operation and maintenance management platform will perform verification when the data is transferred. If the verification finds an abnormality, the frame data will be discarded, and the sender APP will be directly replied with an alarm notification of data abnormality, reminding the APP to self-check and resend the message.

[0085] A3. Encrypt the decrypted first data to be transmitted according to the pipeline key corresponding to the second application to obtain second data to be transmitted.

[0086] In this embodiment, the second data to be transmitted can be understood as data that needs to be transmitted to the second application. After determining that the recipient is the second application, the operation and maintenance management platform determines the pipeline key corresponding to the second application by querying the data table, etc., and encrypts the decrypted first data to be transmitted according to the pipeline key, and the obtained ciphertext data is the second data to be transmitted.

[0087] A4. Send the second data to be transmitted to the second application through the communication channel between the second application, so that the second application decrypts the second data to be transmitted according to the corresponding channel key to obtain the transmitted data.

[0088] The operation and maintenance management platform sends the second data to be transmitted to the second application through the communication channel between the second application. After receiving the second data to be transmitted, the second application can decrypt the second data to be transmitted according to the corresponding channel key to obtain plaintext data, which is the data transmitted by the first application.

[0089] For example, Figure 4 A schematic diagram of data interaction management is provided. The data interaction process of business APP is as follows Figure 4As shown: when the first application APP1 needs to send data to the second application APP2, it is first framed into plain text according to the communication protocol format, and encrypted by the exclusive pipeline key A (the data obtained at this time is the first data to be transmitted), and then sent to the operation and maintenance management platform via an independent communication pipeline. After receiving the ciphertext, the operation and maintenance management platform will first select the paired pipeline key A for decryption and data verification to ensure the reliability of the frame information, and then query the recipient as APP2 through the message identification code, select the paired pipeline key B to re-encrypt the forwarded data (the data obtained at this time is the second data to be transmitted), and send the encrypted message to the destination through the independent communication pipeline of APP2. After receiving the ciphertext, APP2 uses the exclusive pipeline key B to decrypt and obtain the required data, and vice versa. Since the data in each APP communication pipeline is in an encrypted state during the interaction process, and the key is exclusive and cannot be shared, the security and reliability of the communication data can be effectively ensured: even if the data is stolen by a third party, it cannot be decrypted to obtain plain text; even if the data is tampered with, it cannot be received incorrectly through verification.

[0090] The method provided in the embodiment of the present application cancels the interface for direct external communication of the APP for management and security considerations, and the operation and maintenance management platform is responsible for the unified data reading and writing or command control between the user or the upper-level equipment, and the external communication of the business APP must be transferred by the platform.

[0091] As an optional embodiment, this optional embodiment further optimizes and includes B1-B2:

[0092] B1. Periodically sending online inquiry requests to each application through the communication channel of at least one managed application, and determining the running status of the application according to the reply to the online inquiry request.

[0093] In this embodiment, the online inquiry request can be understood as a request for determining whether the application is running normally. The online inquiry request may carry information or may not carry information, and only instruct the application to respond. The running status of the application may be normal, abnormal, etc.

[0094] The operation and maintenance management platform determines each application it manages, and for each application, periodically generates an online inquiry request according to a set period, and periodically sends the generated online inquiry request to the application through the communication channel corresponding to this application. The period for sending online inquiry requests to each application can be the same, or can be set to be different. For example, each application is divided according to type, and the period for applications of the same type is the same. For the convenience of management, the period for sending online inquiry requests for each application can be set to the same period. After receiving the online inquiry request, each application replies, and the operation and maintenance management platform analyzes the received replies and determines the running status of the application based on whether the application has replied. For example, if a reply from the application is received, the running status of the application is determined to be normal, and if no reply from the application is received, the running status of the application is determined to be abnormal.

[0095] As an optional embodiment, this optional embodiment further optimizes determining the running state of the application according to the reply to the online inquiry request, including C1-C2:

[0096] C1. If a response to the online inquiry request from the application is received within a preset time, it is determined that the running status of the application is normal.

[0097] In this embodiment, the preset time can be set according to demand, for example, the preset time is 1s, 5s, etc. The preset time can be set according to the sending period of the online inquiry request, and the preset time is less than the sending period of the online inquiry request, for example, the preset time = 0.5*period.

[0098] For each application, a timer starts after an online inquiry request is sent to it to determine whether the application returns a corresponding response within a preset time; if a response to the online inquiry request from the application is received within the preset time, it is determined that the running status of the application is normal.

[0099] C2. If no response to the online inquiry request from the application is received within a preset time, the operating system interface is called to read the running information of the application, and the running status of the application is determined according to the running information.

[0100] If no response is received from the application to the online inquiry request within the preset time, the operating system interface is called to read the application's running information. The running information may be thread ID, name, running status, CPU occupancy, stack space and stack pointer, etc. The running status of the application is determined by analyzing the running information. For example, when the CPU occupancy of the application is too high, the running status of the application is determined to be abnormal; if the running information of the application is normal, the running status of the application is determined to be normal.

[0101] B2. If the running status of the application is abnormal for a preset number of consecutive times, call the system interface to restart the application with the abnormal running status.

[0102] When the running status of the application is abnormal for a preset number of consecutive times after sending online query requests to the application multiple times, the system interface is called to restart the application with abnormal running status. After the application is restarted, the online query request is continued to be sent periodically to detect the running status of the application.

[0103] As an optional embodiment, this optional embodiment is further optimized to include: if the number of consecutive restarts of an application whose running status is abnormal reaches a preset threshold, and the running status of the application is still abnormal, calling a system restart interface to restart the operating system.

[0104] In this embodiment, the preset number threshold can be set as required, for example, 3, 4, etc. After restarting an application whose running state is abnormal, the number of restarts of the application is recorded, and the running state of the application is continuously detected. If the running state of the application detected for consecutive preset times is still abnormal, the application is continuously restarted. If the number of consecutive restarts of the application reaches the preset number threshold, the running state of the detected application is still abnormal at this time, and the system restart interface is called to restart the operating system. Restarting the operating system may be a soft restart of the operating system.

[0105] If the running state of the application returns to normal, the recorded restart times are cleared; after the operating system is restarted, the recorded restart times of the application can also be cleared.

[0106] The operation and maintenance management platform in the embodiment of the present application also has the functions of APP operation condition management and rapid exception handling, which is used to monitor whether there are any abnormalities in the operation of each business APP and make early warning processing. Figure 5 A flowchart of application operation status monitoring and exception handling is provided. The operation and maintenance management platform monitors the application operation status and handles exceptions. The operation status monitoring and exception handling principles of each application are the same. Figure 5 Taking the monitoring of the operating conditions of an application and handling of exceptions as an example, the specific implementation steps include:

[0107] S1. Broadcast an online inquiry request to the communication channel of the APP.

[0108] During the operation of the low-voltage intelligent circuit breaker, the operation and maintenance management platform will periodically broadcast online inquiry requests to the communication channels of each APP. The cycle time T can be set, and the default value is 20s. The business APP needs to reply within 0.5*T time after receiving the request to indicate that it is still in online operation.

[0109] S2. Determine whether there is an APP that has not responded / has responded for a timeout. If so, execute S3; if not, execute S11.

[0110] S3. Call the operating system interface to read the running information of the APP.

[0111] Among them, the running information of the APP includes at least one of the following: thread ID, name, running status, CPU occupancy, stack space and stack pointer; by reading the running information, it is determined whether there are abnormal situations such as thread exit, high CPU occupancy, stack out of bounds, etc., and an operation alarm record is made.

[0112] S4. Determine the running status of the APP according to the running information. If it is abnormal, execute S5; if it is normal, execute S11.

[0113] S5. Accumulate the abnormal count of the APP.

[0114] The abnormality count accumulation may be increased by a preset value, for example, by 1.

[0115] S6. Determine whether the abnormal count of the APP is greater than the preset number. If so, execute S7; otherwise, execute S11.

[0116] S7. Call the system interface to restart the corresponding APP.

[0117] S8. Accumulate the number of restarts of the APP.

[0118] The restart times accumulation may be increased by a preset value, for example, by 1.

[0119] S9. Determine whether the number of restarts of the APP is greater than a preset number threshold. If so, execute S10; otherwise, execute S12.

[0120] S10. Call the system restart interface to restart the operating system, and execute S12.

[0121] S11. Clear the APP exception count and restart times.

[0122] S12, end.

[0123] For example, if the abnormal phenomenon of the APP still persists after three consecutive query requests, the operation and maintenance management platform calls the system interface to restart the corresponding APP. If the problem is not solved after restarting the APP three times in a row, the operation and maintenance management platform calls the system restart interface to implement a soft restart of the operating system.

[0124] As an optional embodiment, this optional embodiment is further optimized to include: executing the hardware watchdog feeding operation according to a preset period, so that the watchdog monitoring circuit controls the operating system to restart after failing to detect that the operation and maintenance management platform executes the feeding operation within a preset time range.

[0125] The operation and maintenance management platform feeds the watchdog at preset intervals. When the dog feeding operation is not performed within the preset time range, the watchdog monitoring circuit will determine that the operation and maintenance management platform is abnormal and control the operating system to restart.

[0126] In order to ensure the reliable operation of the operation and maintenance management platform itself, an independent hardware watchdog monitoring circuit is designed. The operation and maintenance management platform needs to send a feeding signal to the watchdog monitoring circuit regularly during operation. If the operation and maintenance management platform does not send a feeding signal within the preset time range, the operation and maintenance management platform is judged to be abnormal, and the watchdog monitoring circuit will reset the main chip to restart the operating system. The main chip is the hardware foundation for the entire software operation, and the operating system runs on the main chip. For example, the operation and maintenance management platform feeds the dog regularly every 10 seconds. When it is not executed for 20 consecutive seconds, the watchdog monitoring circuit will determine the abnormality and reset the main control chip to restart the operating system to ensure that the intelligent circuit breaker itself can respond and handle abnormalities in the first time when the operation occurs, instead of relying solely on manual maintenance.

[0127] As the hub of multi-business APP operation and maintenance management, the operation and maintenance management platform also has functions such as APP upgrade management, APP business traffic monitoring management, APP access object statistics management, APP software version management, circuit breaker cumulative operating time and operation event record management.

[0128] The embodiment of the present invention provides a multi-service application operation and maintenance management method based on a low-voltage intelligent circuit breaker, which solves the problem that multiple service APPs in low-voltage intelligent circuit breakers cannot be uniformly scheduled and managed. By building an independent operation and maintenance management platform inside the low-voltage intelligent circuit breaker, the interaction with the operating system is realized, the communication with the user or the upper device is realized externally, and the operation and maintenance management of each APP is realized downward, which can effectively improve the operation reliability and operation and maintenance efficiency of the circuit breaker, reduce the input of manual management, and also facilitate the expansion of new service APPs or functional requirements, and have a better level of intelligence. The APP security loading management function of the operation and maintenance management platform can realize the information authentication, resource allocation, security loading and operation management of the new service APP, with stronger security, more flexible resource allocation mode and higher management efficiency. At the same time, with the help of the system's dynamic distributed loading technology, the operation and expansion of the service APP can be made more independent and convenient. The data interaction management function of the operation and maintenance management platform can realize the communication decoupling and security encryption management of data interaction between service APPs, taking into account the characteristics of simplicity, speed, safety and reliability, and can effectively solve the problem of insufficient communication security between current multi-service APPs, and improve the confidentiality and integrity of interactive data. The APP operating condition management function of the operation and maintenance management platform can rely on the current software architecture to more conveniently realize real-time monitoring of the operating conditions of subordinate business APPs, and has the advantages of rapid identification and autonomous processing of abnormal conditions, which can further improve the operating reliability of circuit breakers and reduce operation and maintenance management costs.

At this time, the application can run normally, and information is exchanged with other applications through the operation and maintenance management platform.
