[0002] Fault recovery refers to the ability of a system to continue to provide acceptable services in the face of a fault. Disaster tolerance refers to the ability to quickly recover and switch to a backup system when a system fails. In the field of energy management of integrated energy systems, in order to ensure the safety and stability of controlled equipment and systems, and to ensure the continuity and quality of energy supply, it is required that a series of key business processes such as monitoring and control of the system can run uninterruptedly, and reliable fault recovery and disaster tolerance technologies are key factors in ensuring system stability.

[0003] In the field of integrated energy systems, currently commonly used fault disaster recovery and disaster tolerance technologies often require intermediate devices such as gateways / intermediate servers to manage the operation and status of the host and backup systems. This will make it impossible for the backup system to be put into use normally when the intermediate device fails. At the same time, this type of traditional solution also has higher construction and operation costs due to the need to introduce intermediate devices. In this context, low-cost, highly reliable fault disaster recovery and disaster tolerance technologies and devices suitable for integrated energy system control terminals are still important research topics in this field.

[0051] Example 1

[0052] Reference Figure 1 , is an embodiment of the present invention, and provides a fault disaster recovery and disaster tolerance method for a comprehensive energy system terminal, comprising:

[0053] S100: The device is initialized and sends information about preempting the host, and determines the host device and the standby device;

[0054] S102: When a host device fails, the host device executes a first action and sends first information to the backup device;

[0055] S104: The standby device receives the first information and starts the first judgment condition, and performs the second action according to the result of the first judgment condition;

[0056] It should be noted that the present invention realizes automatic host and backup machine election between devices through a fault disaster recovery and disaster tolerance method for integrated energy system terminals, ensuring that when a host device fails, it can respond quickly and execute corresponding actions. At the same time, the backup device can be automatically promoted to the host and start the business process based on the fault confirmation result, thereby effectively improving the reliability and stability of the system and ensuring the continuous and stable operation of the integrated energy system.

[0057] In the embodiment of the present application, the above step S100 includes the following sub-steps A1-A4;

[0058] In A1: the device includes a first device and a second device; after the first device and the second device complete initialization after cold start, they send host seizure information to each other within a random time;

[0059] In the embodiment of the present application, the first device and the second device are two completely identical devices;

[0060] In another possible embodiment, the equipment selection can be flexibly adjusted according to the specific actual situation, and equipment with different configurations or performances can be selected. This flexibility stems from the differences in actual situations faced by different integrated energy system control terminals, including but not limited to factors such as system scale, operating environment, cost control, and functional requirements. By selecting equipment based on these actual situations, it can be ensured that the selected equipment can best adapt to and meet the needs of a specific system. However, the above selection method still follows the core principle of the present invention, that is, to achieve automatic commissioning of backup machines in the event of a fault without the need for intermediate equipment, thereby maintaining the continuity of key business processes and the overall stability of the system.

[0061] In A2: the process of determining the host device and the backup device includes: when the second device receives the host seizure information sent by the first device, and the host seizure information of the second device has not been sent, the second device stops sending the host seizure information and sends confirmation information to the first device, the second device is confirmed as the backup device, and after the first device receives the confirmation information of the second device, the first device is confirmed as the host device;

[0062] In A3: when the second device receives the host preemption information sent by the first device, and the host preemption information of the second device has been sent, the second device sends invalid information to the first device, and the first device sends invalid information to the second device. When both devices receive the invalid information sent by the other party, this round of master and backup machine election ends;

[0063] In A4: the first device and the second device repeat the master and backup machine confirmation process until the master and backup machine identities are confirmed.

[0064] It should be noted that the present invention provides a highly flexible and reliable fault disaster recovery and disaster tolerance solution, which is suitable for integrated energy system control terminals. The present invention can be widely adapted to integrated energy systems of different scales and complexities, effectively reducing the cost of system construction and operation; the present invention ensures the continuous operation of key business processes in the event of a host failure through an automatic standby machine commissioning mechanism that does not require intermediate equipment, thereby maintaining the overall stability of the system and the continuity of energy supply.

[0065] In the embodiment of the present application, the above step S102 includes the following sub-steps B1-B3;

[0066] In B1: when the host device fails, the host device responds quickly and automatically executes the degraded operation strategy, executes the fault log recording and reporting strategy, that is, executes the first action;

[0067] In B1, the degraded operation strategy is: when a host failure occurs, the advanced control function is slowed down or shut down according to the degree of the failure, and only the most basic control strategy for maintaining the stable operation of the integrated energy system is retained;

[0068] In a possible embodiment, the advanced control function may include the communication cycle, peak shaving and valley filling, demand response and other functions of the integrated energy system control terminal; taking peak shaving and valley filling as an example for specific explanation: when the host device detects a fault and decides to execute a degraded operation strategy, the severity of the fault and its impact on the overall operation of the integrated energy system are first evaluated. If it is determined that the peak shaving and valley filling function may aggravate the instability of the system or cause uneven resource allocation in the current fault state, the system will automatically trigger an instruction to slow down or shut down the function. Specifically, the peak shaving and valley filling function reduces the energy consumption of non-critical loads during peak energy demand periods and increases the charging of energy storage devices during valley periods through an intelligent scheduling algorithm to balance energy supply and demand. In degraded mode, the system will gradually reduce the execution frequency of the peak shaving and valley filling algorithm until it stops completely. At the same time, the system will send updated control instructions to the integrated energy system control terminal to ensure that all relevant devices can respond to this change in a timely manner and maintain the system in a basically stable state. Through this process, the host device can quickly adjust the control strategy when a fault occurs to ensure system safety while minimizing the impact on user energy use. Ensure that core services such as database services and master-slave communication services remain online and run stably.

[0069] The fault log recording and reporting strategy implemented in B1 includes: when both the host device and the backup device are operating normally, the two machines send heartbeat packets to each other at a specified time interval, and when the two machines receive the heartbeat packets sent by the other machine, they send confirmation data packets to the other machine according to their own status;

[0070] In B2: If the two machines do not receive the confirmation data packet sent by the other party within the set threshold time, or receive the confirmation data packet with fault information sent by the other party, it is considered that the other party's device is in a fault state, and the normal operating device will report the fault to the user;

[0071] In the embodiment of the present application, the two machines send heartbeat packets to each other at a time interval of 5 seconds. If both parties do not receive the confirmation data packet sent by the other party within 10 seconds, it is considered that the other party's device is in a fault state, and both parties take further measures;

[0072] In B3: when a host device fails, the host device automatically records the device failure time and failure data, and sends the first information to the standby device using a heartbeat packet;

[0073] It should be noted that when a host device fails, the present invention can quickly and automatically execute a downgrade operation strategy, adjust the control function according to the degree of failure, ensure that the integrated energy system operates in a basically stable state, and automatically record the failure time and data. Through the dual-machine heartbeat packet mechanism and confirmation data packet exchange, the present invention can monitor the device status in real time, and once a fault is detected, it will immediately report to the user to ensure the timely transmission of fault information. In addition, the heartbeat packet sending at an interval of 5 seconds and the confirmation data packet receiving threshold setting of 10 seconds between the two machines not only ensure the sensitivity of fault detection, but also avoid false alarms caused by instantaneous network jitter.

[0074] In the embodiment of the present application, the above step S104 includes the following sub-step C1;

[0075] In C1: when the standby device receives the first information sent by the host device, the standby device attempts to establish a final communication with the host device to confirm the authenticity of the fault, that is, the first judgment condition;

[0076] The second action in step S104 includes: if the fault is a misjudgment, the heartbeat detection and fault detection process is restored; otherwise, the standby device sends a message to the host device that it is promoted to the host device, and no matter whether the standby device receives a reply from the host device, the standby device identity is changed to the host device, and the service process is started;

[0077] In the embodiment of the present application, the first information includes the failure time and failure data of the host device. In addition to receiving the first information actively sent by the host device to learn about the failure of the host device, the standby device can also learn about it through heartbeat packet detection; the business process includes synchronizing the original host database content, removing the data read and write control rights of the original host, gradually restoring advanced application functions and restoring regular communication frequency, etc.;

[0078] It should be noted that when the standby machine fails, the standby device will send a message to the host to exit the operation group and exit operation; when the device failure is restored, the device will rejoin the host to form an operation group as a standby machine and receive information such as the host's heartbeat packet.

[0079] It should also be noted that the present invention further enhances the system's fault recovery capability and business continuity by introducing an intelligent response mechanism for standby devices; when the standby device receives host fault information or detects an abnormality in a heartbeat packet, it can quickly initiate judgment conditions and take corresponding actions, such as attempting to establish a final communication with the host to verify the authenticity of the fault. Once the fault is confirmed, the standby device will automatically be promoted to the host, ensuring seamless system switching and maintaining stable operation. At the same time, the automatic exit mechanism when the standby device fails and the rejoining mechanism after recovery also ensure the high availability and flexibility of the system.

[0080] The above is a schematic scheme of a method for disaster recovery and disaster tolerance of a comprehensive energy system terminal in this embodiment. It should be noted that the technical scheme of the system for disaster recovery and disaster tolerance of the comprehensive energy system terminal and the technical scheme of the method for disaster recovery and disaster tolerance of the comprehensive energy system terminal described above belong to the same concept.
