Typical embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention.

The general idea of the present invention is: on the one hand, the real-time performance of the dynamic fire-fighting database is guaranteed through the database update step, and the on-site operations that may introduce fire risks that need to be carried out in each area are updated in the dynamic fire-fighting database in real time; on the other hand, through the risk Monitoring step, real-time tracking and monitoring of risks in each area of the power plant, for each area in the dynamic fire database, risk assessment for each field operation that may introduce fire risks, and multiple field operations belonging to the same area The cumulative risk of each area is evaluated in real time based on the results of individual risk assessments for each field operation and the superimposed risk.

In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present application. To illustrate, rather than limit, the technical solutions of the present application, the embodiments of the present invention and the technical features in the embodiments can be combined without conflict.

Embodiment one

This embodiment provides a nuclear power plant fire safety supervision method, the method includes a database updating step and a risk monitoring step. It should be noted that the step of updating the database is to maintain a dynamic firefighting database and ensure the real-time performance of on-site services recorded in the dynamic firefighting database. The dynamic fire database mainly records the information of on-site operations that may introduce fire risks that need to be carried out in each area, and provides data support for the risk monitoring step. The risk monitoring step is based on the information recorded in the dynamic fire database, and monitors the risks of each area in real time. However, in actual execution, there is no necessary relationship between the two steps in the order of execution. These two steps are executed independently. For example, regardless of whether the database update step updates the dynamic fire database, the risk monitoring step is calculated in real time. risk.

In this embodiment, the step of updating the database includes: updating in real time in the dynamic fire database the on-site operations that may introduce fire risks that need to be carried out in each area. Among the many on-site operations of nuclear power plants, the on-site operations that may introduce fire risks mainly include hot work, fire barrier-related operations, storage of combustibles, and storage of hazardous chemicals.

For example, a power plant needs to carry out the following on-site operations: open the fire door 8JSL303PD between rooms L308 and L310 on site. Because the on-site operation will lead to the incomplete boundary of the fire zone 3SFSL0381B, it is considered that the on-site operation may introduce fire risks, and the on-site operation is added and recorded in the dynamic fire protection database. It should be noted that when adding a record to the dynamic fire database for each on-site operation, it will correspond to the relevant job ticket information of the on-site operation (ticket information refers to the information used in the on-site operation in the application approval process) Add it in, and at the same time, it will also record the start and end time of the field work.

Referring to Fig. 1, the risk monitoring steps in this embodiment include:

S101. For each area in the dynamic fire database, perform a separate risk assessment for each on-site operation that may introduce fire risks;

This embodiment provides risk assessment criteria in different dimensions. Specifically, for each field operation, a set of risk assessment criteria (corresponding to a specific dimension) is pre-customized. Different field operations may correspond to risk assessment criteria in different dimensions. According to the risk assessment criteria, the fire risk value of the on-site operation can be quantitatively evaluated to further deepen the fire protection management. For example: the risk assessment criterion for the dimension corresponding to the storage of combustibles is to quantitatively calculate the fire risk value based on the newly added fire load; The spread is quantified to calculate the fire risk value.

S102. Evaluate the superimposed risks of multiple on-site operations belonging to the same area at the same time;

If multiple on-site operations are carried out in a certain area at the same time, it is not only necessary to evaluate the risk of a single operation, but also to comprehensively consider the superimposed risks of multiple operations, especially the interaction between different types of operations, which may cause fire hazards. The risks are far greater than individual job risks.

It should be noted that when dividing the area of the power plant, it can be divided according to the level. For example, the plant is a first-level area, the plant is divided into multiple fire protection areas, and the fire protection area is a second-level area. Each plant or fire protection area has multiple rooms. , each room is a tertiary region. Therefore, the so-called area in the present invention includes factory building, fire protection area, room and so on. Specifically, which areas need to be monitored can be set as required. For example, step S102 may not only assess the superimposed risk of each room, but also consider the superimposed risk of the entire factory building.

As for the calculation of the superimposed risk, the calculation method can be set according to the situation. In a specific implementation, for the room type area, the fire risk value of the superimposed risk can be calculated directly according to the fire risk values of multiple related on-site operations. For example, if on-site business A and B are executed in a certain room at the same time, the superimposed risk of the room can be the fire risk value of on-site business A multiplied by a contribution coefficient and the fire risk value of on-site business B multiplied by a contribution coefficient, corresponding Get after adding. In another specific implementation manner, for a plant-type area, the superimposed risk should not only consider the superimposed risks of on-site operations in each room, but also consider the superimposed risks of on-site operations in different rooms.

In addition, it should be noted that when calculating the superposition risk, the on-site operations participating in the superposition must be at the same time. That is to say, the time when step S102 is performed to calculate the superimposed risk must fall within the time period defined by the start and end times of the selected on-site operations.

S103. Based on the results of the individual risk assessment of each field operation and the superimposed risk, evaluate the cumulative risk of each area in real time;

For example, the fire risk values of various on-site operations in the area obtained in step S101 can be directly accumulated, and then the fire risk value of the superimposed risk calculated in step S102 can be added to obtain the total fire risk value, which can characterize the area cumulative risk. Preferably, the cumulative risk can also be converted into a fire safety risk level. For example, the anti-safety risk level can include low-level, medium-level, medium-high level, and high-level. Each level corresponds to a numerical interval of a fire risk value. According to the fire risk value of the cumulative risk The value interval that falls in can get the fire safety risk level corresponding to the cumulative risk.

S104. According to the on-site business in the area and the fire safety risk level corresponding to the accumulated risk, provide a corresponding prevention strategy formulated in advance;

For example, when the on-site operation of hot work is added to the dynamic fire protection database in the database update step, resulting in the fire safety risk level corresponding to the cumulative risk evaluated in S103 in the risk monitoring step being advanced, then in step S104 provide a pre-set The preventive strategy formulated is as follows: the job applicant is required to supplement the major fire risk plan report, and the fire prevention measures for the entire operation can only be approved.

For another example, when the on-site operation of combustible storage is added to the dynamic fire protection database in the database update step, the fire safety risk level corresponding to the cumulative risk evaluated in S103 in the risk monitoring step is advanced, and then provided in step S104. The pre-established prevention strategy is: the applicant is not allowed to apply, and can modify and choose other storage time (that is, the start and end time of storage of combustibles).

S105 , displaying in real time the fire safety risk levels corresponding to the accumulated risks in each area on the plane indication map of the nuclear power plant.

In order to more intuitively and accurately grasp the fire safety risks of the entire nuclear power plant, preferably, in this embodiment, the geographical location of each fire prevention zone and room in the whole plant is visualized to form a nuclear power plant plane indication map, and the nuclear power plant plane indication Diagrams include area plans of the different floors. On the area plan, each area will display the fire safety risk level corresponding to its own area through color. For example, if a certain level is advanced, it will display red in this area to issue an early warning for managers and remind them to strengthen risk management and control. . For another example, if a certain level is middle-high level, orange will be displayed in this area. If a certain grade is medium, yellow is shown in the area. If a certain grade is low, green is displayed in that area.

The present embodiment will be described below with two specific examples.

For example, for a room-type area, when a certain combustible material is stored in room L301, the fire safety risk level of this area increases to medium level (yellow) due to the increase of fire load in this area, and it will be displayed in the corresponding position of this area on the area plan Displays yellow and provides prevention strategies. When the three on-site operations of storage of combustibles, hot work, and opening of fire barriers occur in room L301 at the same time, although the fire safety risk level of each operation is low (green), the superimposed risk will lead to the fire safety risk of the entire room L301 The grade is intermediate (yellow).

For another example, for a plant-type area, when there are multiple rooms in the plant for on-site operations, the fire safety risk level of each room is low. Since many rooms in the plant are performing on-site operations, although the fire safety risk level of each room is low, considering that the fire protection boundary may be damaged and the fire load is too high, hot work will be very dangerous. Therefore, the plant The cumulative fire safety risk level is likely to be high.

Those of ordinary skill in the art can understand that all or part of the processes in the methods of the above embodiments can be implemented through computer programs to instruct related hardware, and the programs can be stored in a computer-readable storage medium. During execution, it may include the processes of the embodiments of the above-mentioned methods.
