Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear power plant radiation monitoring, and in particular to a KRT system monitoring channel locking management method and system. BACKGROUND

[0002] The nuclear power plant radiation monitoring system (KRT system) is one of the key instrument control systems for the safe operation of a nuclear power plant, and its main functions include: preventing the staff of the nuclear power plant from being exposed to high-dose radiation; preventing the public around the nuclear power plant from being exposed; monitoring the integrity and effectiveness of the reactor barrier; and starting automatic safety measures for the protection of staff or the public. The KRT system monitors the radiation levels of various areas of the nuclear power plant in real time through various radiation detectors, and transmits the monitoring data to the control system. During maintenance and testing in the process of nuclear power plant radiation monitoring, invalid alarms need to be shielded, i.e. locked. According to the nuclear industry specifications and actual operation experience, for non-nuclear level alarm signals without interlocking action, the signals are transmitted to the KRT system server through RS485 communication, and then transmitted to the DCS by the server. Correspondingly, the locking is realized by software configuration in the KRT system service.

[0003] The existing software locking method has the following problems: 1. Lack of a dedicated operation interface: the existing KRT system does not have a dedicated radiation monitoring channel alarm locking state tracking operation interface, and the alarm locking state of the radiation channel cannot be effectively tracked. The operator needs to check the locking state through multiple scattered interfaces, which is inefficient and prone to errors.

[0004] 2. Lack of permission management: the channel unlocking and locking operation does not have an operation permission management function, and unauthorized operations cannot be prevented. Many investigations of nuclear power plant incidents have shown that many false locking incidents are caused by unauthorized personnel. 3. Unclear identification: the radiation channels in the unlocking and locking interface are identified by internal names (such as "CH001", "CH002", etc.), which cannot intuitively identify the real radiation monitoring channel name, and the user operation error rate is high. 4. The existing software locking operation process is complicated and requires professional personnel to operate, and the user learning cost is high.

Obtain a configuration file set, parse and extract the content of the configuration file set, and convert it into structured data, the content of the configuration file set including: channel name and closed-loop state of the monitoring channel; In this step, the configuration file set contains closed-loop related information of all KRT system monitoring channels, at least including the channel name and closed-loop state of the monitoring channel, wherein the channel name is a real physical location description of the monitoring channel rather than an internal code, such as "1KRT001MA", and the closed-loop state is the current state of the monitoring channel corresponding to the closed-loop or non-closed-loop. The configuration file set can be automatically scanned at a certain frequency (such as every 5 minutes) to obtain the content of the configuration file set and ensure that the closed-loop related information is updated in real time. By parsing and extracting the content of the configuration file set, the structured closed-loop information data is converted for subsequent reading and display.

[0020] In some optional embodiments, the configuration file set includes a first configuration file recording the channel ID and the channel name, and a second configuration file recording the channel ID and the lock state. In step S1, the first configuration file and the second configuration file are acquired, the mapping relationship between the channel ID, the channel name and the lock state is established, and the mapping relationship is converted into structured data. Specifically, when the configuration file set includes two configuration files recording the lock-related information, the contents of the two configuration files are acquired in step S1. The channel ID is a unique identifier. The mapping relationship between the channel name and the lock state is established through the channel ID, and is output as structured data.

[0021] S2. According to the content of the structured configuration file set, the data items of the plurality of monitoring channels are respectively displayed through the plurality of content display areas of the first main interface. Each content display area is associated with a data item. The data item at least includes the channel name and the corresponding lock state. In this step, the structured lock information data is respectively displayed through the plurality of content display areas of the first main interface. The arrangement style of the content display areas can be set as needed. The displayed channel name is a real physical position description of the monitoring channel rather than an internal code, for example, “1KRT001MA”. The lock state is the current state of the monitoring channel, which is locked or unlocked. By displaying the real physical position, the user can intuitively identify the real monitoring channel name, thereby reducing the misoperation rate.

[0022] S3. Receiving a selection action of a user on the content display area, and superimposing a second operation interface on the first main interface. The second operation interface includes a plurality of operation buttons. The operation buttons at least include a lock button and an unlock button.

[0024] S5. Receiving the input information of the input box of the second operation interface or the input box of the third operation interface, judging whether the input information is consistent with the preset data, if consistent, performing the action corresponding to the target operation button.

[0025] In this step, the type of input information is determined by business requirements, and the user is prompted to input the required content in the operation interface. The input information of the user is obtained and compared with the correct preset data. If the comparison result is consistent, the action corresponding to the target operation button is performed, such as locking or unlocking the corresponding channel. A prompt information of operation success can be given. If the comparison result is inconsistent, the corresponding action is not performed, and a prompt information of operation failure can be given until the user inputs the correct information.

[0026] In some optional embodiments, the input box of the second operation interface or the input box of the third operation interface is an operation password input box. In step S5, the operation password input by the user is received, and it is judged whether the operation password is consistent with the preset correct password. If consistent, the action corresponding to the target operation button is performed. Specifically, the operation password can be the password of the current logged-in user, a uniformly set lock password, or a one-time password, etc. By setting a secondary verification mechanism, unauthorized operations are avoided, the human error lock rate is reduced, and the overall safety level of the nuclear power plant is improved.
