The operation and maintenance management platform firstly selects a pairing pipeline key A for decryption and data verification after receiving the ciphertext, ensures the reliability of frame information, inquires the receiver as APP2 through a message identification code, selects a pairing pipeline key B for re-encrypting forwarding data (the data obtained at the moment is second data to be transmitted), sends the encrypted message to a destination through an independent communication pipeline of the APP2, and the APP2 can obtain the required data by decrypting through the special pipeline key B after receiving the ciphertext, and vice versa. The data in each APP communication pipeline is in an encryption state in the interaction process, and the exclusive key can not be shared, so that the safety and reliability of communication data can be effectively ensured, the data can not be decrypted to obtain clear text even if the data is stolen by a third party, and the data can not be received by error through verification even if the data is tampered.

In the method provided by the embodiment of the application, the interface of the APP direct external communication is canceled in consideration of management and safety, and the operation and maintenance management platform is uniformly responsible for data read-write or instruction control with a user or superior equipment, so that the external communication of the service APP is transferred by the platform.

As an alternative embodiment, this alternative embodiment further optimizes the inclusion of B1-B2:

b1, periodically sending an online query request to each application program through the communication pipeline of the at least one managed application program, and determining the running state of the application program according to the reply of the online query request.

In this embodiment, an online query request may be understood as a request for determining whether an application program is operating normally. The online query request may or may not carry information, and only instructs the application to answer. The running state of the application may be normal, abnormal, etc.

The operation and maintenance management platform determines each managed application program, periodically generates an online query request according to a set period for each application program, and periodically transmits the generated online query request to the application program through a communication pipeline corresponding to the application program. The period of sending the online query request to each application may be the same or may be different, for example, the applications are divided by type, and the periods of the same type of application are the same. For convenience of management, the transmission period of the line query request of each application may be set to the same period. Each application program replies after receiving the online query request, the operation and maintenance management platform analyzes the received replies and determines the running state of the application program according to whether the application program replies, for example, the received replies of the application program determine that the running state of the application program is normal, and the received replies of the application program determine that the running state of the application program is abnormal.

As an alternative embodiment, the present alternative embodiment further optimizes determining the running state of the application based on the reply to the online query request, including C1-C2:

And C1, if the reply of the application program for the online query request is received within the preset time, determining that the running state of the application program is normal.

In this embodiment, the preset time may be set according to requirements, for example, the preset time is 1s, 5s, etc., and the preset time may be set according to a transmission period of the online query request, where the preset time is smaller than the transmission period of the online query request, for example, the preset time=0.5×period.

And starting timing after sending the online query request to each application program, judging whether the application program returns a corresponding reply or not within a preset time, and if the reply of the application program for the online query request is received within the preset time, determining that the running state of the application program is normal.

And C2, if the reply of the application program for the online query request is not received within the preset time, calling an operating system interface to read the running information of the application program, and determining the running state of the application program according to the running information.

If the reply of the application program for the online query request is not received within the preset time, the operating system interface is called to read the operating information of the application program, wherein the operating information can be a thread ID, a name, an operating state, a CPU occupancy rate, a stack space, a stack pointer and the like, the operating state of the application program is determined by analyzing the operating information, for example, when the CPU occupancy rate of the application program is too high, the operating state of the application program is determined to be abnormal, and if the operating information of the application program is normal, the operating state of the application program is determined to be normal.

And B2, if the running states of the application programs are abnormal in continuous preset times, calling the system interface to restart the application programs with abnormal running states.

And after the online query request is sent to the application program for multiple times, if the running states of the application program with the continuous preset times are abnormal, calling a system interface, and restarting the application program with the abnormal running states. After the application program is restarted, the on-line inquiry request is continuously and periodically sent, and the running state of the application program is detected.

As an optional embodiment, the further optimization of the optional embodiment includes that if the continuous restarting times of the application program with abnormal running state reach the preset times threshold, the running state of the application program is still abnormal, and a system restarting interface is called to restart the operating system.

In this embodiment, the preset number of times threshold may be set according to the requirement, for example, 3, 4, etc. After restarting the application program with abnormal running state, recording the restarting times of the application program, continuously detecting the running state of the application program, continuously restarting the application program if the running state of the application program detected by the continuous preset times is still abnormal, and calling a system restarting interface to restart the operating system if the continuous restarting times of the application program reaches the preset times threshold value. Restarting the operating system may be a soft restart of the operating system.

If the running state of the application program is recovered to be normal, resetting the recorded restarting times; after restarting the operating system, the number of restarts of the recorded application program may also be cleared.

The operation and maintenance management platform in the embodiment of the application also has APP operation condition management and rapid exception handling functions, and is used for monitoring whether the APP operation of each service is abnormal and performing early warning treatment. FIG. 5 provides a flow chart of monitoring and exception handling of an application program, wherein the operation and exception handling of the application program is monitored and performed by an operation and maintenance management platform. The operating condition monitoring and exception handling principles of each application are the same, and fig. 5 is an example of monitoring and exception handling of an operating condition of an application, and specifically includes the following implementation steps:

s1, broadcasting and sending an online query request to a communication pipeline of the APP.

In the running process of the low-voltage intelligent circuit breaker, the operation and maintenance management platform can periodically broadcast and send an online query request to the communication pipelines of all the APPs, the period time T can be set, and the default value is 20s. The service APP needs to reply within 0.5×t of the received request to indicate that the current state is still in online operation.

S2, judging whether the APP does not reply or replies with overtime, if so, executing S3, and if not, executing S11.

S3, calling an operating system interface to read the running information of the APP.

The APP operation information comprises at least one of thread ID, name, operation state, CPU occupancy rate, stack space and stack pointer, and judges whether abnormal conditions such as thread exit, CPU occupancy rate is too high, stack out-of-limit and the like occur or not by reading the operation information, and makes operation alarm records.

S4, determining the running state of the APP according to the running information, executing S5 if abnormal, and executing S11 if normal.

S5, accumulating the abnormal count of the APP.

The anomaly count increment may be an increment of a preset value, for example, an increment of 1.

S6, judging whether the anomaly count of the APP is larger than a preset number of times, if so, executing S7, otherwise, executing S11.

S7, calling a system interface to restart the corresponding APP.

S8, accumulating the restarting times of the APP.

The restart times accumulation may be an increase of a preset value, for example, an increase of 1.

S9, judging whether the restarting times of the APP is larger than a preset times threshold, if so, executing S10, otherwise, executing S12.

S10, calling a system restarting interface to restart the operating system, and executing S12.

S11, clearing the APP anomaly count and the restarting times.

S12, ending.

Illustratively, if the anomaly is still maintained after 3 consecutive query requests by the APP, the operation and maintenance management platform invokes the system interface to restart the corresponding APP. If the problem is not solved after the APP is restarted for 3 times continuously, the operation and maintenance management platform calls a system restarting interface to realize the soft restarting of the operating system.

As an optional embodiment, the optional embodiment further comprises executing the hardware watchdog feeding operation according to a preset period, so that the watchdog monitoring loop controls the operating system to restart after the watchdog monitoring loop does not detect that the operation and maintenance management platform executes the feeding operation within a preset time range.

The operation and maintenance management platform feeds dogs at regular intervals of a preset period, and when the dog feeding operation is not executed within a continuous preset time range, the watchdog monitoring loop judges that the operation and maintenance management platform is abnormal and controls the operating system to restart.

In order to ensure reliable operation of the operation and maintenance management platform, an independent hardware watchdog monitoring loop is designed, the operation and maintenance management platform needs to send a watchdog feeding signal to the watchdog monitoring loop at regular time during operation, when the operation and maintenance management platform is not detected to send the watchdog feeding signal within a preset time range, the operation and maintenance management platform is judged to be abnormal, the watchdog monitoring loop resets a main chip to restart an operating system, wherein the main chip is a hardware base of whole software operation, and the operating system is operated on the main chip. For example, the operation and maintenance management platform feeds dogs at intervals of 10 seconds, when the continuous 20 seconds are not executed, the watchdog monitoring loop can judge the abnormality and reset the main control chip to restart the operating system, so that the intelligent circuit breaker can respond and process at the first time when the abnormality occurs in operation, and the intelligent circuit breaker does not depend on manual maintenance only.

The operation and maintenance management platform is used as a central of multi-service APP operation and maintenance management, and further has functions of APP upgrade management, APP service flow monitoring management, APP access object statistics management, APP software version management, breaker accumulated running time, operation event record management and the like.

The embodiment of the invention provides a multi-service application program operation and maintenance management method based on a low-voltage intelligent circuit breaker, which solves the problem that multi-service APP cannot be uniformly scheduled and managed in the low-voltage intelligent circuit breaker, and realizes interaction with an operating system, communication with a user or superior equipment and operation and maintenance management of each APP on the upper side and the lower side on the lower side by constructing an independent operation and maintenance management platform in the low-voltage intelligent circuit breaker, so that the operation reliability and operation and maintenance efficiency of the circuit breaker can be effectively improved, the labor management investment is reduced, and the expansion of newly-added service APP or functional requirements is facilitated, and the method has a better intelligent level.
