[0028] In the embodiments of the present disclosure, the control system refers to a system formed by introducing a microprocessor, sensor technology, and network communication technology. It has the characteristics of intelligent control, intelligent perception, intelligent application, intelligent diagnosis, and intelligent recovery. The operation process of the control system often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, the control system can realize remote control and management of the control system by the user by connecting to the user's device.

[0030] At present, the use of various control systems has become very common, among which the use of chiller group control systems and building control systems in energy saving has also become very common. Control systems often have problems due to various reasons, but operators are always helpless to solve the problems due to insufficient understanding of the system. To this end, the relevant technology proposes a fault detection method, including: receiving a fault instruction, the fault instruction is obtained based on the operating status data of the faulty monitoring equipment; comparing and analyzing the fault instruction with a preset fault database to obtain the fault information and fault solution corresponding to the fault instruction, the fault database represents the corresponding relationship between the fault instruction and the fault information and fault solution; sending the fault information and fault solution to a mobile terminal for display.

[0031] Although the relevant technology has a certain fault diagnosis capability, when a system failure occurs, the manufacturer or operator still needs to manually confirm and execute the fault solution. The control system cannot be restored by itself, and the actual user experience is poor.

[0032] Combination Figure 1 As shown, the embodiment of the present disclosure provides a fault handling method for a control system, comprising:

[0033] S101, when a control system fails, the processor obtains a fault handling strategy.

[0034] S102: The processor determines a disturbance level of the control system affected by the fault handling strategy.

[0035] S103: The processor controls the execution of the fault handling strategy according to the disturbance level.

[0036] By using the fault handling method for a control system provided by the embodiment of the present disclosure, when a fault occurs in the diagnosis control system, the embodiment of the present disclosure obtains the corresponding fault handling strategy to assist the user in fault handling. In addition, the embodiment of the present disclosure takes into account that the fault handling strategy may cause certain interference to the operation of the control system and the controlled device. By further obtaining the disturbance level of the fault handling strategy acting on the control system, the embodiment of the present disclosure can control the fault handling strategy to be more reasonably executed at the right time, thereby achieving the non-disturbance self-recovery of the control system, which is conducive to improving the user experience.

[0037] Optionally, combined Figure 2 As shown, the processor obtains a fault handling strategy, including:

[0038] S201, the processor obtains operation information of the control system.

[0039] S202: The processor determines the cause of the failure of the control system according to the operation information of the control system.

[0040] S203: The processor determines a corresponding fault handling strategy according to the fault cause of the control system.

[0041] In this way, the disclosed embodiment can analyze the cause of the control system failure by monitoring the operating information of the control system, and then match the corresponding fault handling strategy to assist the user in fault handling, which is conducive to improving the user experience.

[0042] Optionally, the operating information of the control system includes part or all of the operating environment information, program operating information and controlled device information of the control system. By monitoring the above operating information, the embodiment of the present disclosure can identify abnormal information therefrom and analyze the possible causes of the control system failure accordingly, thereby facilitating the acquisition of an accurate fault handling strategy.

[0043] Optionally, the processor determines a corresponding fault handling strategy according to the fault cause of the control system, including: when the fault cause of the control system is a system fault, determining the fault handling strategy to repair the system file and restart the system; or, when the fault cause of the control system is a program fault, determining the fault handling strategy to repair the program file and restart the program. In this way, the embodiment of the present disclosure can match an accurate fault handling strategy according to the specific fault cause of the control system, thereby helping the user to complete fault repair.

[0044] Optionally, the processor determines the corresponding fault handling strategy according to the cause of the control system failure, and also includes: when the cause of the control system failure is an engineering failure, determining the fault handling strategy to repair the engineering file, restart the project, and restore the working parameters. In this way, the embodiment of the present disclosure can further distinguish engineering failures and can provide a more accurate fault handling strategy to enhance the self-recovery capability of the control system. In addition, it can be understood that in most scenarios, restarting the project and restarting the program have almost the same interference with the operation of the controlled device. Therefore, the monitoring and control of the program in the subsequent embodiments can also be equivalent to the monitoring and control of the project, and the embodiment of the present disclosure does not specifically limit this.

[0045] Optionally, the disclosed embodiment may further include more fault handling strategies, not limited to the above-mentioned fault handling strategies. The fault handling strategy may be determined according to the cause of the control system fault, which is not listed here one by one. At the same time, based on the above-mentioned multiple fault handling strategies, the control system may select an appropriate time to execute them.

[0046] Optionally, combined Figure 3 As shown, the processor determines the disturbance level of the fault handling strategy acting on the control system, including:

[0047] S301: The processor determines a disturbance level corresponding to a fault handling strategy according to step information of the fault handling strategy.

[0048] S302: The processor corrects the disturbance level corresponding to the fault handling strategy according to the operation information of the control system, and determines it as the disturbance level of the fault handling strategy acting on the control system.

[0049] In this way, the disclosed embodiment can analyze the step information of the fault handling strategy, and determine the corresponding disturbance level by judging the degree of interference of its steps on the operation of the control system and the controlled equipment. Furthermore, the disclosed embodiment obtains the operation information of the control system to judge the actual working conditions of the control system and the controlled equipment, so as to analyze its anti-interference ability. And by making reasonable corrections to the disturbance level corresponding to the fault handling strategy based on this, the disclosed embodiment can obtain the accurate disturbance level of the fault handling strategy that ultimately acts on the control system, which is conducive to more reasonable execution of the fault handling strategy at the right time, so as to achieve disturbance-free self-recovery of the control system, and then help to ensure the operational stability of the control system and the controlled equipment.

[0050] Optionally, the processor determines the disturbance level corresponding to the fault handling strategy according to the step information of the fault handling strategy, including: when the fault handling strategy includes a restart step, the processor determines that the disturbance level corresponding to the fault handling strategy is medium or high; or, when the fault handling strategy does not include a restart step, the processor determines that the disturbance level corresponding to the fault handling strategy is low. In this way, the embodiment of the present disclosure determines the corresponding disturbance level by judging whether the restart step is involved in the fault handling strategy. When the restart step is involved in the fault handling strategy, the restart step may affect the program operation and device output of the control system, and may even cause the controlled device to shut down in severe cases. Therefore, the fault handling strategy has a high degree of interference with the operation of the control system and the controlled device, and the embodiment of the present disclosure determines that the corresponding disturbance level is medium or high. When the restart step is not involved in the fault handling strategy, since the control system or the system operation program does not need to be restarted when the fault is recovered, the operation of the control system and the controlled device is relatively stable, so the fault handling strategy has a low degree of interference with the operation of the control system and the controlled device, and the embodiment of the present disclosure determines that the corresponding disturbance level is low.

[0051] Optionally, the processor determines that the disturbance level corresponding to the fault handling strategy is intermediate or advanced, including: when the restart object is a program, the processor determines that the disturbance level corresponding to the fault handling strategy is intermediate; or, when the restart object is a system, the processor determines that the disturbance level corresponding to the fault handling strategy is advanced. In this way, the embodiment of the present disclosure can determine the corresponding disturbance level according to the specific action object of the restart step in the fault handling strategy. When the restart object is a program, the degree of interference of the restart program to the controlled device is relatively high, but the interference to the control system itself is relatively small, so the embodiment of the present disclosure determines that its corresponding disturbance level is intermediate. When the restart object is a system, it is mostly accompanied by the repair of the system and the system environment, and the fault handling strategy has a high degree of interference to the operation of the control system itself. And it affects the normal operation of more controlled devices, which is easy to cause many devices to unexpectedly shut down, and there is a great risk. Therefore, the degree of interference of the restart system to the controlled device is extremely high, and the embodiment of the present disclosure determines that its corresponding disturbance level is advanced.

[0052] Optionally, the processor corrects the disturbance level corresponding to the fault handling strategy according to the operation information of the control system, including: when the operation information of the control system indicates that the program is not running, the processor corrects the disturbance level corresponding to the fault handling strategy to a low level; or, when the operation information of the control system indicates that the program is running, the processor corrects the disturbance level corresponding to the fault handling strategy according to the operation of the controlled device. In this way, the embodiment of the present disclosure can judge the actual working conditions of the control system and the controlled device according to the operation information of the control system, and then analyze its anti-interference ability, which is conducive to reasonable correction of the disturbance level corresponding to the fault handling strategy, so as to obtain the accurate disturbance level of the fault handling strategy that ultimately acts on the control system. When the operation information of the control system indicates that the program is not running, it indicates that the group control association mechanism has not been established between the control system and the controlled device at this time. At this time, the fault recovery of the control system itself is difficult to interfere with the operation of the controlled device. Therefore, the embodiment of the present disclosure corrects the disturbance level corresponding to the fault handling strategy to a low level, so as to perform fault self-recovery in time after confirming the non-disturbance environment. When the operating information of the control system indicates that the program is running, the embodiment of the present disclosure further monitors the operating status of the controlled device to determine the degree of interference that the fault handling strategy may cause to the operation of the controlled device, and reasonably corrects the disturbance level corresponding to the fault handling strategy accordingly, which is conducive to more reasonable execution of the fault handling strategy at the right time.

[0053] Optionally, the processor modifies the disturbance level corresponding to the fault handling strategy according to the operation of the controlled device, including: when the controlled device is not running, the processor reduces the disturbance level corresponding to the fault handling strategy; or, when the controlled device is running, the processor maintains the disturbance level corresponding to the fault handling strategy. In this way, the embodiment of the present disclosure can modify the disturbance level corresponding to the fault handling strategy according to the operation of the controlled device to improve the reliability of the execution of the fault handling strategy. When the controlled device is not running, it is difficult for the fault recovery of the control system itself to interfere with the controlled device in the current state. The embodiment of the present disclosure appropriately reduces the disturbance level corresponding to the fault handling strategy to improve the reliability of the execution of the fault handling strategy. When the controlled device is running, since the control program is also running at this time, the group control association mechanism has been established between the control system and the controlled device, and the operation of the controlled device is highly disturbed by the fault recovery of the control system. The embodiment of the present disclosure maintains the disturbance level corresponding to the fault handling strategy, in order to more reasonably execute the fault handling strategy at the right time.

[0054] Exemplarily, when the controlled device is not running, the processor reduces the disturbance level corresponding to the fault handling strategy, including: when the controlled device is not running and the restart object is a program, the processor corrects the disturbance level corresponding to the fault handling strategy to a low level; or, when the controlled device is not running and the restart object is a system, the processor corrects the disturbance level corresponding to the fault handling strategy to a medium level. In this way, when the controlled device is not running, it is difficult for the fault recovery of the control system itself to cause interference to the controlled device in the current state. The disclosed embodiment can improve the reliability of the execution of the fault handling strategy by appropriately reducing the disturbance level corresponding to the fault handling strategy.

[0055] Optionally, when the fault handling strategy includes a restart step, it also includes: the processor determines the operation status of the restart compensation mechanism; the processor corrects the disturbance level corresponding to the fault handling strategy according to the operation status of the restart compensation mechanism. In this way, the embodiment of the present disclosure can also determine whether the control system can restore the original operating state after the restart is completed by determining the operation status of the restart compensation mechanism. And by correcting the disturbance level corresponding to the fault handling strategy accordingly, the embodiment of the present disclosure can further improve the reliability of the execution of the fault handling strategy.

[0056] Optionally, the restart compensation mechanism includes a power-off hold function and / or an online synchronization function. By monitoring the enabled status of functions such as power-off hold and online synchronization, the embodiment of the present disclosure can determine the operation of the restart compensation mechanism to reasonably correct the disturbance level corresponding to the fault handling strategy.

[0057] Optionally, the processor corrects the disturbance level corresponding to the fault handling strategy according to the operation of the restart compensation mechanism, including: when the restart compensation mechanism is running, the processor maintains the disturbance level corresponding to the fault handling strategy; or, when the restart compensation mechanism is not running, the processor increases the disturbance level corresponding to the fault handling strategy. In this way, by determining the operation of the restart compensation mechanism, the embodiment of the present disclosure can determine whether the control system has the ability to restore the original operating state after the restart is completed. When the restart compensation mechanism operates normally, it indicates that the control system can restore the original operating state after the restart is completed. Therefore, the degree of interference in the operation of the control system and the controlled device will gradually decrease after the fault repair is completed. Therefore, the embodiment of the present disclosure maintains the disturbance level corresponding to the fault handling strategy to improve the reliability of the execution of the fault handling strategy. When the restart compensation mechanism is not running, it indicates that the control system does not have the ability to restore the original operating state after the restart is completed. With the execution of the fault handling strategy, the degree of interference with the operation of the control system and the controlled device will be maintained at a high level for a long time. Therefore, the embodiment of the present disclosure increases the disturbance level corresponding to the fault handling strategy, in order to more reasonably execute the fault handling strategy at the right time.

[0058] Exemplarily, when the restart compensation mechanism is not running, the processor increases the disturbance level corresponding to the fault handling strategy, including: when the restart compensation mechanism is not running and the restart object is a program, the processor corrects the disturbance level corresponding to the fault handling strategy to a high level. In this way, when the restart compensation mechanism is not running, it indicates that the control system does not have the ability to restore the original operating state after the restart is completed. With the execution of the fault handling strategy, the degree of interference with the operation of the control system and the controlled device will remain at a high level for a long time. Therefore, the embodiment of the present disclosure increases the disturbance level corresponding to the fault handling strategy, in order to more reasonably execute the fault handling strategy at the right time.

[0059] Optionally, combined Figure 4 As shown, the processor controls the execution of the fault handling strategy according to the disturbance level, including:

[0060] S401, when the disturbance level is low, the processor controls the control system to execute a fault handling strategy. Or,

[0061] S402: When the disturbance level is medium, the processor controls the control system to send a fault handling strategy to the user equipment. Or,

[0062] S403, when the disturbance level is high, the processor determines a new fault handling strategy, and controls the control system to send the fault handling strategy and the new fault handling strategy to the user equipment.

[0063] In this way, the disclosed embodiment can judge the degree of interference caused by the execution of the fault handling strategy on the operation of the control system and the controlled device according to the disturbance level of the fault handling strategy acting on the control system, and by selecting a suitable execution scheme, it can improve the reliability of the execution of the fault handling strategy. Specifically, when the disturbance level is low, it indicates that the execution of the fault handling strategy at this time has a low degree of interference with the operation of the control system and the controlled device. Therefore, the disclosed embodiment controls the control system to directly execute the fault handling strategy, and promptly turns on the disturbance-free self-recovery of the control system, which is conducive to improving the user experience. When the disturbance level is medium, it indicates that the execution of the fault handling strategy at this time has a high degree of interference with the operation of the control system and the controlled device. Therefore, the disclosed embodiment controls the control system to send the fault handling strategy to the user device, and simultaneously pushes the current risk to the user, so that the user can judge whether to execute the fault handling strategy and determine the specific execution time. When the disturbance level is high, it indicates that the execution of this version of the fault handling strategy at this time will cause a very high degree of interference to the operation of the control system and the controlled equipment. Therefore, the disclosed embodiment controls the control system to find a new fault handling strategy, and sends the new and old fault handling strategies to the user device together. At the same time, the effect comparison and risk analysis of the new and old fault handling strategies are also pushed to the user simultaneously, so that the user can determine which version of the fault handling strategy to execute and determine the corresponding execution time.

[0064] Optionally, when the disturbance level is medium, after the processor controls the control system to send the fault handling strategy to the user device, the method further includes: in response to the fault recovery instruction sent by the user, the processor controls the control system to execute the fault handling strategy. In this way, after receiving the fault recovery instruction sent by the user, the embodiment of the present disclosure can reasonably execute the fault handling strategy based on the execution timing selected by the user, thereby realizing self-recovery of the control system, which is conducive to improving the user experience.

[0065] Optionally, when the disturbance level is high, the processor determines a new fault handling strategy, and after controlling the control system to send the fault handling strategy and the new fault handling strategy to the user device, it also includes: in response to the fault recovery instruction sent by the user, the processor controls the control system to determine and execute the target fault handling strategy. In this way, after receiving the fault recovery instruction sent by the user, the embodiment of the present disclosure can further determine the target fault handling strategy from the old and new fault handling strategies, and reasonably execute the target fault handling strategy based on the execution timing selected by the user, so as to realize the self-recovery of the control system, which is conducive to improving the user experience.

[0066] Combination Figure 5As shown, the embodiment of the present disclosure provides a fault handling device for a control system, including a self-diagnosis module 501 and a decision module 502. The self-diagnosis module 501 is configured to obtain a fault handling strategy when a fault occurs in the control system.

[0067] By using the fault handling device for a control system provided by the embodiment of the present disclosure, when a fault occurs in the diagnosis control system, the embodiment of the present disclosure obtains the corresponding fault handling strategy to assist the user in fault handling. In addition, the embodiment of the present disclosure takes into account that the fault handling strategy may cause certain interference to the operation of the control system and the controlled device. By further obtaining the disturbance level of the fault handling strategy acting on the control system, the embodiment of the present disclosure can control the fault handling strategy to be more reasonably executed at the right time, thereby realizing the non-disturbance self-recovery of the control system, which is conducive to improving the user experience.

[0068] Optionally, the fault handling device for a control system further includes a self-recovery module 503. The self-recovery module 503 is configured to execute a fault handling strategy to self-recover the faulty part of the control system.

[0069] Optionally, the fault handling device for the control system also includes a recovery storage area 504. The recovery storage area 504 is configured to store inherent data and operating data to assist the self-recovery module 503 in realizing self-recovery of the control system. Optionally, the recovery storage area 504 includes an operating parameter storage area 5041, an OS (Operating System) system file storage area 5042 and a system boot area 5043. The operating parameter storage area 5041 is configured to store operating parameter data of the program. The OS system file storage area 5042 is configured to store inherent file data of the control system and the program. The system boot area 5043 is configured to determine and retrieve backup data from the operating parameter storage area 5041 and the OS system file storage area 5042. Thus, the recovery storage area 504 can assist in the repair of related files and the restoration of working parameters to realize self-recovery of the control system.

[0070] Optionally, the fault handling device for a control system further comprises an external data interface 505. The external data interface 505 is configured to perform data transmission with a user device, so as to send fault information and a fault handling strategy to the user.
