Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the on-line maintenance method of the device of the present invention. The equipment online maintenance method is applied to a parallel operation system, and comprises the following steps:
Step S10, when detecting that equipment faults exist in the parallel operation system, determining equipment types of faulty equipment;
In this embodiment, the parallel operation system refers to a system formed by parallel operation of a plurality of electrical devices (including, but not limited to, a frequency converter, a rectifier and an energy storage converter), and generally one parallel operation system includes a master machine and a plurality of slave machines, where the master machine is used to send control instructions to each slave machine, and each slave machine operates according to the control instructions sent by the master machine. It should be noted that, in a practical situation, one or more slaves may fail in the parallel operation system, the master may fail, or the master and the slaves may fail, so the device type of the failed device may be the master type and/or the slave type.
Specifically, each device in the parallel operation system monitors the running state of the device, and each device also sends its own state information to other devices in the system (for example, may send heartbeat messages), so when the device in the system stops running due to a fault, the system can determine the device with the fault in time, and further learn the device type of the fault device.
Step S20, according to the equipment type, carrying out corresponding fault tolerance adjustment on the parallel operation system to maintain the operation of the parallel operation system, and removing the fault equipment from the parallel operation system;
and step S30, if the maintained equipment to be put into is determined to pass through a preset overhaul process, accessing the equipment to be put into the parallel operation system until the maintenance of the fault equipment is completed, wherein the overhaul process comprises a buffer detection process and/or an operation detection process.
In this embodiment, the fault-tolerant adjustment policy corresponding to the master type is different from the fault-tolerant adjustment policy corresponding to the slave type. When the system only has the slave machine type or only has the equipment of the master machine type to fail, the system adopts the fault-tolerant adjustment strategy corresponding to the master machine type or the slave machine type, and when the master machine and the slave machine in the system fail, the system can simultaneously adopt the two fault-tolerant adjustment strategies. The overhaul flow at least comprises a buffer detection flow and/or an operation detection flow, and other overhaul flows can be added according to actual requirements.
Specifically, for the host type, the fault tolerance adjustment policy may be that a device is selected from the slave devices in the system as a new host device to take over the failed host to continue instruction transmission while (or after) removing the failed host from the system, and for the slave type, the slave device may be directly removed from the system because its removal will not affect the system, or the host in the system may be notified, and the host reassigns the task to be executed to the other normally operating slave device, while (or after) removing the failed slave device from the system to timely assign the task originally executed by the failed slave device to the other slave device to complete, thereby avoiding delay of task execution progress.
After the faulty device is removed, the faulty device can be repaired or replaced. After maintenance or replacement is completed, the maintained equipment or newly replaced equipment can be used as equipment to be put into preparation for accessing the original parallel operation system. It should be noted that, before the device to be put into operation is connected to the system, it is generally required to overhaul the device to be put into operation to confirm that the device to be put into operation has no abnormality in performance of each function, because of the system stability and safety.
The embodiment provides an equipment online maintenance method, which comprises the steps of firstly determining equipment types of equipment when a parallel operation system fails, then carrying out corresponding fault-tolerant operation on the system according to different equipment types, so that the system can still maintain a normal operation state after the failure occurs, timely removing failed equipment from the system, maintaining or replacing the failed equipment under the condition that the normal operation of the system is not affected, and re-accessing the equipment to be input into the system after the maintenance or replacement is completed and the equipment to be input is confirmed to pass through a preset maintenance flow comprising a buffer detection flow and/or an operation detection flow, so that the normal operation of the system is not disturbed in the whole process from the failure occurrence to the failure removal re-access of the equipment in the parallel operation system, namely the system can always carry out normal production, and the technical problem of high maintenance cost of the existing failure removal mode of the parallel operation is solved.
Further, based on the first embodiment shown in fig. 2, a second embodiment of the device online maintenance method of the present invention is proposed. In this embodiment, the device types include a master type and a slave type, and step S20 includes:
Step S21, if the equipment type of the fault equipment is a host type, changing the equipment type of the fault equipment into a slave type, and selecting a new host from a plurality of slaves of the parallel operation system except the fault equipment;
and step S22, maintaining the operation of the parallel operation system based on the new host, and removing the fault equipment from the parallel operation system.
In this embodiment, when the system detects that the host fails and cannot operate normally, the failed host needs to be changed to a slave first, and a new host needs to be selected from the slaves in the system to serve as the new host, and then the failed host that has been lowered to the slave needs to be removed from the system.
The selection strategy of the new host can be flexibly set according to actual conditions, specifically, a slave is selected from all the slaves in normal operation states in the slave system to serve as the new host, and a slave which is most suitable for the standard is selected from all the slaves in normal operation states to serve as the new host according to certain parameter standards.
According to the embodiment, when the host fails, a new host is rapidly contended from the slaves which are currently running, so that the fact that other slaves can continuously receive a correct control instruction is guaranteed, and stable running of the system is guaranteed.
Further, the step of selecting a new host from a plurality of slaves of the parallel operation system except for the faulty device in step S21 includes:
Step S211, obtaining state information and number information of the slaves, and selecting the new master according to the state information and the number information.
In this embodiment, the status information refers to information reflecting the operation status of the device, and may be specifically classified into a normal operation status and an abnormal status. The number information refers to a device number uniquely corresponding to each device.
Specifically, for selecting a new host, the system can obtain the state information of each slave device, screen the slave device with normal operation state from the state information, and then select the slave device with the largest (or smallest) device number from the slave devices with normal operation state as the new host.
Further, step S30 includes:
Step S31, determining to-be-put equipment after maintenance or replacement until a new equipment addition access instruction is received;
and S32, executing the overhaul flow on the equipment to be input, and accessing the equipment to be input into the parallel operation system after the overhaul is passed, wherein a direct current power switch of the equipment to be input is not switched on in the overhaul process.
In this embodiment, the device newly-added access instruction may be initiated to the system by a related maintainer. After the maintenance personnel complete the maintenance of the fault equipment, the maintenance personnel send an equipment newly-added access instruction to the system. After the system receives the instruction, the equipment to be put into is determined to be connected, then the equipment to be put into is overhauled according to a preset overhauling flow, each function of the equipment to be put into can be overhauled specifically, the equipment to be put into can be connected into the system after each function is confirmed to be normal, and specific operation of the system to be connected comprises switching on a direct current power supply switch of the equipment to be put into.
Before the maintenance is finished, the direct-current power switch of the equipment to be put into operation is always in an off state, so that the running state of the equipment to be put into operation is ensured not to influence the system, and the system is ensured to run stably all the time.
Further, based on the above second embodiment, a third embodiment of the online maintenance method of the device of the present invention is proposed. In the present embodiment, step S32 includes:
step S321, judging whether the buffer function of the equipment to be put into is normal;
step S322, if yes, judging whether the equipment to be put into can normally operate;
step S323, if yes, judging that the equipment to be put into the operation passes maintenance;
And step S324, switching on the direct-current power supply switch of the equipment to be input so as to switch the equipment to be input into the parallel operation system.
In the present embodiment, the buffer function is verified mainly by changing the on-off state of the ac power switch of the equipment to be put into operation. The system judges whether the buffering function of the equipment to be input is normal or not by changing the opening and closing state of an alternating current power switch, if the equipment to be input fails, the equipment to be input is indicated to have abnormal functions, the system cannot be accessed at the moment, further investigation is needed, the specific system can output abnormal prompt information on a display interface to prompt maintenance personnel to overhaul failure, if the equipment to be input is normal, the system continues to judge whether the equipment to be input can normally operate, if the equipment to be input can normally operate at the moment, the equipment to be input can be judged to pass overhaul, the equipment to be input can be accessed to the system at the moment, and if the equipment to be input can not normally operate (can be judged by operating error information), the equipment to be input can not pass through an overhaul flow, and the equipment to be input can not be accessed to the system at the moment.
Further, step S321 includes:
step S3211, determining that both the alternating current power switch and the direct current power switch of the equipment to be put into operation are switched off;
step S3212, switching on the AC power switch, and judging whether the actual DC side voltage value of the equipment to be put into is consistent with a standard DC side voltage value;
Step S3213, if yes, judging that the buffering function of the equipment to be put into is normal;
Step S3214, if not, judging that the buffering function of the equipment to be put into is abnormal.
In this embodiment, the system firstly ensures that the ac power source and the dc power source of the device to be put into operation are both switched off (i.e. not energized), then switches on (i.e. energized) the ac power switch, and judges whether the actual dc side voltage value of the device to be put into operation is consistent with the standard dc side voltage value at this time, so as to detect the buffer function of the device to be put into operation, if so, the system can judge that the buffer function of the device to be put into operation is normal, the specific system can output the prompt information of normal function on the display interface, and if not, the system can judge that the buffer function verified at this time is abnormal, and can also output the prompt information of abnormal function on the display interface.
Further, the device type includes a master type and a slave type, and step S20 includes:
And step A, if the equipment type of the fault equipment is the slave type, informing a host in the parallel operation system to carry out task redistribution to a plurality of slaves except the fault equipment so as to maintain the operation of the parallel operation system, and removing the fault equipment from the parallel operation system.
In this embodiment, if the slave device in the system fails, the system may notify the host of the failure, and after knowing that the host may redistribute the tasks to be executed next to the other slaves, the task originally executed by the failed slave is transferred or distributed to the other slaves that are normally executed, so as to ensure that all tasks can be normally advanced, and then the failed slave is removed from the system for maintenance alone.
As a specific example, fig. 3 shows.
When the system enters a maintenance operation mode aiming at equipment to be put into operation, firstly, a direct current power switch and an alternating current power switch of the equipment to be put into operation are switched off, after switching off completion is confirmed, the alternating current power switch is switched on, after switching off completion is confirmed, whether the direct current side voltage value of the equipment to be put into operation is consistent with a standard value is judged to judge whether the pre-charging is completed or not (namely, a buffering function is detected), if the direct current side voltage value is inconsistent with the standard value, a Human-machine interface (HMI, human MACHINE INTERFACE) prompts maintenance failure and switching off the alternating current power switch, if the direct current side voltage value is consistent with the standard value, the pre-charging is judged to complete, whether the equipment to be put into operation can be normally operated is continuously, if the equipment to be put into operation can not be normally operated, the maintenance failure is prompted through the Human-machine interface, and if the equipment to be overhauled successfully is prompted through the Human-machine interface. After the overhaul is successful, the system firstly breaks the AC power switch to be put into the equipment to exit from the overhaul operation mode, then enters the normal operation mode after the break is completed, and in the mode, the DC power switch and the AC power switch to be put into the equipment are switched on to formally access the system, and the equipment can normally operate after being accessed into the system.
