Embodiment 1

[0039] Such as figure 1 As shown, Embodiment 1 of the present invention provides a processing system for nuclear power plant unit start-up and shutdown alarms, including: unit state pre-selection module 1, which is used to receive unit status information during the operation of nuclear power plant units, and pre-select important The unit status of the alarm; the alarm analysis module 2 is connected with the unit status preselection module 1, and is used to determine the alarm range according to the unit status of the alarm according to the needs, and sort out and classify the multiple alarms that occur; the alarm display and processing module 3. Connected with the alarm analysis module 2, for layout according to the importance level of the alarms sorted out by the alarm analysis module 2 and display the alarms in the same display area, and process the alarms , All alarms are displayed in the same area so that operators can monitor all important alarm information to avoid omiss...

Embodiment 2

[0070] Such as image 3 As shown, Embodiment 2 of the present invention provides a processing method for starting and stopping alarms of nuclear power plant units, including the following steps:

[0071] S1. Receive the status information of the unit during the operation of the nuclear power plant unit, and pre-select the status of the unit that needs to be issued with an important alarm;

[0072] S2. According to the unit status determined in step S1 that needs to be alarmed, determine the alarm range, and sort out and classify multiple alarms that appear;

[0073] S3. Layout according to the importance levels of the alarms sorted out in the step S2, and collectively display the alarms on the same display area, and process the alarms.

[0074] Specifically, the importance levels of the alarms in the step S2 are laid out in a manner that increases sequentially from the edge of the display area to the center of the display area.

[0075] In this embodiment, the normal operati...

Embodiment 3

[0078] Such as Figure 4 As shown, in this embodiment, step S3 includes:

[0079] S31. Centrally display the alarm information classified in step S2 according to the alarm importance level;

[0080] The alarm information displayed in step S31 specifically includes: alarm type, alarm content, and alarm importance; each alarm card is used to display the corresponding alarm value, alarm reason, and subsequent processing flow so that the operator can handle the alarm.

[0081] S32. Automatically process the alarm or provide a manual processing link and an alarm card, so that the operator can manually process the alarm.

[0082] combine figure 2 and Figure 4 As shown, in this embodiment, the classified alarm information is displayed on the display screen of the power station computer and the control system, and the alarm information on the display screen is divided into five categories: reactivity, cooling-related, barrier integrity, compressed air pressure, and regulator Wat...

Abstract

The invention discloses a processing system for starting and stopping alarms of nuclear power plant units. The system includes a unit status preselection module, an alarm analyzing module and an alarmdisplaying and processing module, wherein the unit status preselection module is used for receiving unit status information during the operation of a nuclear power plant unit, and preselecting the unit status which needs to perform an important alarm; the alarm analyzing module is connected to the unit status preselection module, and used for determining an alarm range according to the unit status which needs to perform the alarm and performing combing and classifying on the appeared multiple alarms; and the alarm displaying and processing module is connected to the alarm analyzing module, and is used for performing a layout according to the importance grade of the sorted alarms, centrally displaying the alarms on the same display area, and performing processing on the alarms; A processing method for starting and stopping alarms of nuclear power plant units is also disclosed. The processing system and method are convenient for operators to monitor important alarm information and the importance grade of the alarms, and can timely perform corresponding processing on the alarms.

Description

technical field [0001] The invention relates to the field of operation and management of nuclear power plants, in particular to a processing system and method for starting and stopping alarms of nuclear power plant units. Background technique [0002] Nuclear power plants are generally maintained within the normal operating range, but when the process parameters deviate from the operating range, the equipment status does not match the actual operating status of the current process system, the equipment fails, or the system equipment is no longer operable, an alarm will be generated. The purpose of the alarm is to remind the operator of the event, and require the operator to intervene in the process to eliminate or alleviate the fault, so that the nuclear power plant can return to normal state. [0003] In the prior art, combined alarms or single alarms are used. When combined alarms are used, the operator must rely on the indicator or view other information to determine the ...
