[0044] The following details the specific implementation manners of the present invention in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0045] Figure 1 It is the flow chart of the alarm method of the nuclear power unit provided by the present invention; Figure 2 It is the alarm flow chart of the nuclear power unit provided by the present invention; Figure 3 It is the structural schematic diagram of the alarm device of the nuclear power unit provided by the present invention; Figure 4 It is the structural schematic diagram of the alarm system of the nuclear power unit provided by the present invention; Figure 5 It is the working flow chart of the alarm system of the nuclear power unit provided by the present invention.

[0046] As Figure 1 shown, the embodiments of the present invention provide an alarm method for a nuclear power unit, and the method includes:

[0047] Step 1: Obtain the current alarm type of the nuclear power unit and the current control authority of the nuclear power unit;

[0048] Step 2: Based on the current control authority, determine the alarm execution end, and the alarm execution end includes: the main control server or the backup panel;

[0049] Step 3: Based on the current alarm type, generate a corresponding alarm instruction, and send the corresponding alarm instruction to the alarm execution end, so that the alarm execution end controls the corresponding alarm mechanism to generate an alarm according to the alarm instruction.

[0050] Specifically, in this embodiment, the nuclear power unit includes a main control server and a backup panel, both of which are suitable for implementing the control of the unit. Among them, the main control server is embedded with a computerized control system (IIC). During the operation of the nuclear power unit, under normal circumstances, the control authority lies with the computerized control system (IIC). The operator monitors the nuclear power plant at the operator workstation. The flashing of the alarm indicator and the sound emitted on the display of the operator station remind the operator of the occurrence of abnormal conditions. In the case of the triggering or disappearance of safety attention alarms, process alarms, instrument control failures, or changes in the unit's operating conditions, the operator workstation emits sounds in different tones and ringing patterns for reminder. The backup panel (BUP) mainly serves as a backup means after the failure of the digital technology in the main control room, and is used for safely shutting down the reactor and maintaining the reactor at the cold shutdown level as well as handling accident conditions. Specifically, it realizes three functions: alarm, display, and control. Its safety and reliability are very important for ensuring the safe shutdown of the reactor.

[0051] However, currently, the alarm sound systems of the main control server (computerized control system - IIC) and the backup panel (BUP) cannot be uniformly managed. When the alarm on one side is activated, the alarm sound reminder on the other side is not effectively suppressed, which brings interference to the operator's alarm handling, easily leads to misjudgment, and there are potential safety hazards. Therefore, in this embodiment, after receiving the alarm of the nuclear power unit, first obtain the current alarm type of the nuclear power unit, and at the same time obtain whether the current control authority of the nuclear power unit belongs to the main control server (computerized control system - IIC) or the backup panel (BUP). If the current control authority lies with the main control server (computerized control system - IIC), then control the corresponding alarm mechanism to give an alarm through the main control server (computerized control system - IIC). If the current control authority lies with the backup panel, the operator no longer needs to pay attention to the alarm interface and sound of the operator station, and the backup panel (BUP) conducts alarm monitoring. The flashing of the alarm light and the single ringing of the buzzer on the backup panel remind the operator of abnormal conditions. When the control authority in the main control room switches from IIC to BUP or from BUP to IIC, develop a nuclear power alarm sound management method to ensure that while the alarm sound on the side in the control mode is activated, the alarm sound on the non-control mode side is suppressed, shielding the interference of invalid alarm sounds, reducing the burden on the operator to monitor and handle alarms, effectively avoiding the possibility of human error, and thus ensuring the safe operation of the nuclear power plant. By adopting this method, it is possible to effectively reduce the interference and burden of the operator during the alarm handling process, reduce misjudgment, and improve the operating safety of the unit.

[0052] In another embodiment, when the main control server (Computerized Control System - IIC) and the backup panel (BUP) receive an alarm end instruction, they control the corresponding alarm mechanism to stop alarming.

[0053] Furthermore, the alarm instruction includes an alarm type, and the alarm type includes at least one of safety attention alarm, general alarm, process alarm, and instrument control failure alarm.

[0054] Specifically, in this embodiment, in order to achieve comprehensive control of the operation of the nuclear power unit, it is necessary to monitor the operation parameters, environment, its own structural components, monitoring equipment, etc. of the nuclear power unit. Therefore, different alarm types are specifically set to achieve differentiation, facilitating quick identification and understanding of the alarm reasons. In this embodiment, the safety attention alarm includes: abnormal alarm of the unit's own structure, etc.; the general alarm includes: abnormal environment alarm, etc.; the process alarm includes: abnormal alarm of steam temperature, pressure, flow, etc. in the nuclear power unit, etc.; the instrument control failure alarm includes: self - failure alarm of instruments and control systems in the nuclear power unit, etc.

[0055] Furthermore, the alarm type has a corresponding alarm priority, and the alarm priority from high to low is: safety attention alarm, general alarm, process alarm, and instrument control failure alarm.

[0056] Specifically, in this embodiment, since there may be a situation where multiple alarm types are triggered simultaneously, however, in the case of multiple types of alarms, some alarm - corresponding situations are more urgent. Therefore, the alarm priorities of different alarm types are defined to accurately identify the alarm category with the highest priority, so that the most urgent type generates an alarm first. By sounding a special sound, it reminds the operator, enabling the power plant operator to accurately distinguish the alarms that need to be processed first among multiple types of alarms, effectively avoiding the keyhole effect of the digital alarm system in the main control room, and taking targeted measures in a timely manner to avoid serious consequences.

[0057] In another embodiment, the BUP only needs to judge three states: process alarm trigger, all alarms disappear, and safety attention alarm trigger, and there is no requirement for priority. After judgment, it outputs 3 hard points to the buzzer with multi - channel input to achieve different sounding modes for the three working conditions.

[0058] Furthermore, the alarm execution end controls the alarm mechanism to generate an alarm according to the alarm instruction, including:

[0059] Based on the alarm type, control the alarm mechanism to alarm according to different tones and different preset time intervals according to the alarm priority corresponding to the alarm type.

[0060] Specifically, in this embodiment, in order to accurately distinguish anomalies of different importance levels, an alarm method according to different priorities is adopted, and different alarm types are distinguished. For different alarm types, alarm forms with different tones and different preset time intervals are set to assist the staff in making timely distinctions and taking corresponding measures.

[0061] Furthermore, based on the alarm type, the alarm mechanism is controlled to give alarms according to different tones and different preset time intervals corresponding to the alarm type, including:

[0062] If the alarm type is a safety notice alarm, the alarm mechanism is controlled to give a sound alarm according to the first tone and the first preset time interval;

[0063] If the alarm type is a general alarm, the alarm mechanism is controlled to give a sound alarm according to the second tone and the first preset time interval;

[0064] If the alarm type is a process alarm, the alarm mechanism is controlled to give a sound alarm according to the third tone and the second preset time interval;

[0065] If the alarm type is an instrument control fault alarm, the alarm mechanism is controlled to give a sound alarm according to the third tone and the third preset time interval;

[0066] The first preset time interval is less than the third preset time interval, and the third preset time interval is less than the second preset time interval.

[0067] Specifically, in this embodiment, the alarm priorities of alarm types from high to low are as follows: safety attention alarm, general alarm, process alarm, and instrument control failure alarm. Therefore, the reminders for safety attention alarms and general alarms need to be more vigilant. Therefore, when the current alarm type corresponding to the alarm instruction is a safety attention alarm, the alarm mechanism is controlled to sound an alarm according to the first tone and the first preset time interval; when the current alarm type corresponding to the alarm instruction is a general alarm, the alarm mechanism is controlled to sound an alarm according to the second tone and the first preset time interval; wherein, the first preset time interval is shorter, and the frequency of the first tone is higher than that of the second tone, so that the sound of the safety attention alarm is more piercing and continuous than that of the general alarm, playing a better reminder role. In addition, when the current alarm type corresponding to the alarm instruction is a process alarm, the alarm mechanism is controlled to sound an alarm according to the third tone and the second preset time interval, wherein the frequency of the third tone is less than that of the second tone, and the time interval for sounding the alarm is set to the second preset time interval, which is less than the first preset time interval, so that the sound of the process alarm is more gentle and intermittent than that of the general alarm, playing a better role in distinguishing and reminding. When the current alarm type corresponding to the alarm instruction is an instrument control failure alarm, the alarm mechanism is controlled to sound an alarm according to the third tone and the third preset time interval, wherein the frequency of the third tone is less than that of the second tone, and the time interval for sounding the alarm is set to the third preset time interval, which is less than the second preset time interval. In comparison, the alarm sound of the instrument control failure alarm is the gentlest and intermittent, thus playing a better role in distinguishing and reminding.

[0068] In a specific embodiment, as Figure 2 shown, the sound ringing tones and time intervals are determined in advance, and three tones and three modes are preset in the system of the alarm mechanism: the first is: continuous ringing, the second is: short sound (default 3s, adjustable), and the third is: long sound (default 30s, adjustable). Matching the sound ringing mode: ① Corresponding the above working conditions to the sound ringing mode: when a safety attention alarm occurs → tone 3 rings continuously; when a general alarm occurs (except for safety attention alarms) → tone 1 rings continuously; when a process alarm (a change in the calculation working condition occurs) → tone 2 rings with a long sound; when an instrument control failure alarm (an I&C failure occurs) → tone 2 rings with a short sound; when all types of alarms disappear → tone 1 rings with a short sound. ② Coding the above ringing methods starting from 1, and each ringing method has a unique code, and 0 means no ringing. ③ Determining the sound coding clearing working condition: pressing the mute button → all alarm sounds stop; pressing the confirmation button on the working condition screen → tone 2 rings with a long sound.

[0069] Furthermore, the method further includes:

[0070] If it is determined that the alarm execution end is the main control server, after sending an alarm instruction to the main control server, it is judged whether an alarm execution signal feedback from the main control server is received. If not, the alarm instruction and a first communication failure instruction are sent to the backup panel.

[0071] If it is determined that the alarm execution end is the backup panel, after sending an alarm instruction to the backup panel, it is judged whether an alarm execution signal feedback from the backup panel is received. If not, a determination alarm instruction and a second communication failure instruction are sent to the main control server.

[0072] Specifically, in this embodiment, since there may be an abnormal communication link between the main control server and the backup panel, therefore, when it is determined that the alarm execution end is the main control server and after sending an alarm instruction to the main control server, if the alarm execution signal feedback from the main control server is not received, it is considered that the main control server cannot give an alarm reminder normally, and it is necessary to send an alarm instruction and a first communication failure instruction (the first communication failure instruction is used to indicate that there is an abnormality in the communication of the main control server) to the backup panel for reminder; when it is determined that the alarm execution end is the backup panel and after sending an alarm instruction to the backup panel, if the alarm execution signal feedback from the backup panel is not received, it is considered that the backup panel cannot give an alarm reminder normally, and it is necessary to send an alarm instruction and a second communication failure instruction (the first communication failure instruction is used to indicate that there is an abnormality in the communication of the backup panel) to the main control server for reminder.
