Description

Technical Field

[0001] The present invention relates to the field of ecological early warning, and in particular to a biosafety early warning method, device, equipment and storage medium. Background Art

[0002] Nuclear power is a clean energy source. my country, facing electricity shortages, has a strategically important national goal. However, marine biomass outbreaks can clog nuclear power plant cooling systems, causing reactors to overheat and shut down, seriously threatening the normal operation of nuclear power plants. Early warning of zooplankton population changes at cooling water intakes plays a guiding role in addressing biosafety issues in nuclear power cooling systems.

[0003] To effectively intercept marine life, a semi-enclosed bay will be constructed near the nuclear power plant's cooling water intake for salvaging marine life. Multiple monitoring devices will be deployed in the forebay to monitor marine life populations in real time. While these monitoring devices can provide alerts for marine life outbreaks, they are often belated or false alarms, making their effectiveness limited. The primary reason for this is the lack of a targeted early warning model. For one thing, the location of the monitoring devices is poor, overlooking the biological habits and flow characteristics within the bay. Furthermore, the monitoring results cannot be rationally linked to ecological processes, lacking the ability to predict future ecological changes. Consequently, the current solution suffers from low accuracy. Summary of the Invention

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0056] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 The first embodiment of the biosafety early warning method in the embodiment of the present invention includes:

[0057] 101. Obtain the initial biological data corresponding to the pre-set semi-enclosed harbor where the cold source water intake of the nuclear power plant is located. The initial biological data includes: initial biological data in the active water area and initial biological data in the still water area;

[0058] It is understandable that the execution subject of the present invention can be a biosafety early warning device, or a terminal or a server, which is not limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0059] It should be noted that semi-enclosed harbors are hotbeds for marine life. The rapid reproduction and growth of marine life in specific areas is the main cause of biological blockage at water intakes. Figure 10 This is a schematic diagram of a semi-enclosed harbor in an embodiment of the present invention. The nuclear power plant's cooling water intake is located downstream of the active water zone, which is located outside the semi-enclosed harbor, while the still water zone is located inside. This invention divides the harbor based on flow field characteristics and models ecological processes within and between zones. This allows for prediction of biomass changes at the water intake over the next few days based on current monitoring results.

[0060] 102. Calculate the biomass of the initial data of organisms in the active water area and the initial data of organisms in the still water area according to a preset ratio to obtain the biomass of the active water area and the biomass of the still water area;

[0061] Specifically, the total biomass in the still water area on a given day consists of three parts: the first part is the organisms that enter the still water area on that day; the second part is the growth of biomass in the previous water exchange cycle and the transport of organisms from the still water area to the active water area caused by water exchange; the third part is the biomass transported from the still water area to the active water area through water exchange on that day, such as Figure 6 shown.

[0066] It should be noted that if Figure 7 As shown, the biomass growth rate is the growth of biological weight, covering both quantity and length increment. The biomass growth rate is regulated by different factors and can be set by the model user. The present invention provides the relationship between growth and seasonal changes. Mid-February is the season for large-scale reproduction of plankton. The closer to this time point, the higher the growth rate. This relationship is characterized by a normal distribution. The biomass growth rate calculation formula is:

[0074]

[0075] Among them, F t (t) represents the biomass that migrates from the still water area to the active water area, F m represents the local biological environment capacity, T n is the time constant.

[0076] In an embodiment of the present invention, initial biological data corresponding to a preset semi-enclosed harbor where a nuclear power plant's cold source water intake is located is obtained, wherein the initial biological data includes: initial biological data in a flowing water zone and initial biological data in a still water zone; biomass is calculated for the initial biological data in the flowing water zone and the initial biological data in the still water zone according to a preset ratio to obtain the biomass of the flowing water zone and the biomass of the still water zone; the biomass of the still water zone is input into a preset population reproduction prediction model to perform biomass prediction to obtain a biomass prediction value; the biomass of the flowing water zone is transmitted in real time to a monitoring terminal at the cold source water intake of the nuclear power plant, and the biomass prediction value is transmitted to the monitoring terminal at the cold source water intake of the nuclear power plant according to a preset daily ratio; and a biosafety warning is issued to the cold source water intake of the nuclear power plant via the monitoring terminal based on the biomass of the flowing water zone and the biomass prediction value.
