[0002] In recent years, with the wide application of hydrogen fuel cells, the corresponding power generation system is also becoming more and more complex, so the requirement for the fault handling capability of the power generation system is also increasing. Generally, the fault handling process of the hydrogen fuel cell power generation system is: fault triggering-system shutdown or load reduction-fault alarm. During the period from fault triggering to system shutdown or load reduction, a series of related faults are often triggered, and the system will report all the occurring faults to the display interface without distinction. According to actual experience, more than 90% of the faults are caused by first faults, but in the prior art, since the first fault cannot be distinguished, the after-sales maintenance personnel need to rely on experience to analyze the faults one by one, resulting in low fault handling efficiency.

[0028] Figure 1A step flow chart of a first failure determination method provided by an embodiment of the present application is shown in the figure;

[0029] Figure 2 A structural schematic diagram of a first failure determination device provided by an embodiment of the present application is shown in the figure. DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application.

[0031] Please refer to Figure 1 For an embodiment of the present application, a first failure determination method is provided, which is suitable for a PLC processor. The PLC processor includes n failure data storage sub-areas, n failure flag registers and an output state register. Each failure data storage sub-area stores a type of failure information. Each failure flag register includes (n-1) failure flag bits. Each failure data storage sub-area is associated with (n-1) failure flag registers, and corresponds to a failure flag bit in each associated failure flag register.

[0032] The first failure determination method includes:

[0033] Step S1: obtaining a failure signal and determining a failure type corresponding to the failure signal.

[0034] Preferably, the obtaining of the failure signal includes monitoring the failure according to a plurality of sensors to obtain the failure signal.

[0035] In a preferred embodiment, the first failure determination method disclosed by the present application is suitable for a hydrogen fuel cell power generation system. The PLC processor inside the hydrogen fuel cell power generation system monitors failure signals according to sensors. One failure signal may include a plurality of failure sub-signals, i.e., the failure information corresponding to the failure signal includes the failure information corresponding to a plurality of failure sub-signals. Since each module in the hydrogen fuel cell power generation system may generate several sub-failures in a very short time, and these sub-failures correspond to a type of failure, such as a type of representing an alarm but not stopping; a type of representing load reduction or power limitation but not stopping; a type of representing a delay stop; a type of representing an instantaneous stop, an operation and maintenance personnel can determine the failure point through one sub-failure. Therefore, these sub-failures can be packaged as one failure signal, which is convenient for identification in subsequent failure information storage and reduces the partition memory, so that the failure processing is more efficient.

[0036] Step S2: determining a target fault data storage sub-area corresponding to the fault signal according to the fault type, and then storing the fault information corresponding to the fault signal into the target fault data storage sub-area;

[0037] In a preferred embodiment, after a fault signal is generated in the hydrogen fuel cell power generation system, a series of other faults can be triggered, and these faults are stored in corresponding fault data storage sub-areas in sequence. By reading the fault data storage sub-areas, all the fault information can be obtained.

[0038] Step S3: when a change in the target fault data storage sub-area is monitored, refreshing the (n-1) fault flag registers associated with the target fault data storage sub-area, so that the state value of the fault flag bit corresponding to the target fault data storage sub-area in the register associated with the target fault data storage sub-area is changed;

[0039] In a preferred embodiment, when a change in a fault data storage sub-area is monitored, it is regarded as a target fault data storage sub-area, and the (n-1) fault flag registers associated with it are immediately updated, so that the state value of the fault flag bit corresponding to the target fault data storage sub-area is changed. Therefore, the internal storage of the above (n-1) fault flag registers has new storage content compared with the initial time. For example, if there are currently 4 types of faults, and the fault type corresponding to the target fault data storage sub-area is type 1, then the state value of the fault flag bit corresponding to type 1 in the 3 fault flag registers associated with it is updated. If the initial sequence values of the 3 fault flag registers are (0, 0, 0), (0, 0, 0), and (0, 0, 0), respectively, the updated values are (1, 0, 0), (1, 0, 0), and (1, 0, 0), respectively. 1类 3类 4类 1类 2类 4类 1类 2类 3类 1类 3类 4类 1类 2类 4类 1类 2类 3类

[0040] Step S4: outputting the state values of the fault flag bits of all the fault flag registers to an output state register, so that the output state register generates a control signal according to the received state values of the fault flag bits;

[0041] ​​​​​​​​​​​​​​​​​​In a preferred embodiment, a unique control signal is generated in the output state register according to the outputs of the n fault flag registers, such as the sequence values of the updated 3 fault flag registers (1 1类 , 0 3类 , 0 4类 ), (1 1类 , 0 2类 , 0 4类 ), (1 1类 , 0 2类 , 0 3类 ) above, whose binary groups are represented as 100, 100, 100, and the continuous 3 rectangular signals are generated according to the binary groups, and then a control signal is composed, and the amplitudes of the continuous 3 rectangular signals in this embodiment are 4-4-4 respectively, that is, the corresponding binary groups are converted into decimal.

[0042] Step S5: comparing the control signal with a preset first-failure control signal, and determining that the fault corresponding to the fault signal is a first-failure fault when the control signal is consistent with the preset first-failure control signal.

[0043] In a preferred embodiment, when a preset first-failure control signal corresponding to the fault signal is input as the first input, the generated control signal, such as a Class 1 fault, will have a preset first-failure control signal, and the amplitudes of the 3 continuous rectangular signals contained in the preset first-failure control signal are 4-4-4. After the control signal is generated in the PLC processor, it is compared with the preset first-failure control signal corresponding to the Class 1 fault. When the comparison is consistent, it means that the Class 1 fault is a first-failure fault. When the comparison is inconsistent, it means that the Class 1 fault is not a first-failure fault.

[0044] Preferably, after determining that the fault corresponding to the fault signal is a first-failure fault, the method further comprises: controlling an alarm to alarm the first-failure fault.

[0045] Preferably, when the control signal is determined to be inconsistent with the preset first-failure control signal, it is determined that the fault corresponding to the fault signal is a non-first-failure fault.

[0046] After determining that the fault corresponding to the fault signal is a first-failure fault, the fault information corresponding to the first-failure fault is sent to an upper computer, so that the upper computer displays the fault information in a first display area.

[0047] After determining that the fault corresponding to the fault signal is a non-first-failure fault, the fault information corresponding to the non-first-failure fault is sent to an upper computer, so that the upper computer displays the fault information in a second display area.

[0048] The first display area and the second display area are different.

[0049] In a preferred embodiment, the acquired control signal is compared with a preset first-failure control signal, and when the comparison is consistent, it indicates that the fault corresponding to the fault signal is a first-failure, and when the comparison is inconsistent, it indicates that the fault corresponding to the fault signal is a non-first-failure, and further, the host computer displays the first-failure information and the non-first-failure information after judgment, so that the first-failure information and other non-first-failure information can be understood in time, and then the operation and maintenance personnel are informed to process.
