Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a method for regulating the temperature of a nuclear power capacitor is provided, which is described by taking the method as an example applied to a computer device, and comprises the following steps:
102, acquiring multi-point temperature information corresponding to the interior of a nuclear power container through a plurality of fiber bragg grating sensors; a plurality of fiber grating sensors are arranged in the same nuclear power container.
And 104, comparing the multipoint temperature information with a preset temperature threshold interval to obtain a plurality of comparison results.
And 106, determining a target comparison result meeting a preset adjusting condition in the plurality of comparison results.
And step 110, adjusting the corresponding target comparison result according to the corrected temperature information.
In the process of monitoring the temperature of the nuclear power container, the temperature information in the nuclear power container can be acquired through a plurality of fiber grating sensors on the optical fiber. A plurality of fiber grating sensors may be connected in series on the optical fiber. The fiber grating sensor may be a fiber grating temperature sensor. The fiber bragg grating temperature sensor obtains temperature information by modulating the fiber bragg wavelength by the physical temperature quantity, so that the physical temperature quantity is directly measured.
And the computer equipment acquires the temperature information of the corresponding measuring points in the nuclear power container output by the plurality of fiber bragg grating sensors. Each measuring point can correspond to one fiber grating sensor, and the measuring point can be the main position of the nuclear power container. The form of the temperature information may be a physical quantity obtained by processing information generated by a plurality of fiber grating sensors by a computer device, or a set of numerical values corresponding to the physical quantity obtained in the process of processing the information generated by the fiber grating sensors, and may be binary data, or other types of data such as 16-ary data. For example, the temperature information may be a temperature value of 25 degrees, or may be a set of binary data corresponding to a temperature value of 25 degrees. The form of the temperature information is not limited herein.
In one embodiment, acquiring the multi-point temperature information corresponding to the inside of the nuclear power container through a plurality of fiber grating sensors includes: acquiring multipoint temperature information corresponding to each moment in the core capacitor in a preset time period through a plurality of fiber bragg grating sensors; comparing the multipoint temperature information with a preset temperature threshold interval to obtain a plurality of comparison results, wherein the comparison results comprise: and comparing the multipoint temperature information corresponding to each moment with a preset temperature threshold interval to obtain a plurality of comparison results corresponding to each moment.
The temperature information may be obtained in various ways. The computer equipment can acquire multipoint temperature information corresponding to the interior of the nuclear capacitor output by the plurality of fiber bragg grating sensors in real time, and can also acquire multipoint temperature information corresponding to the nuclear capacitor at each moment in a preset time period. For example, the temperature information may be temperature information of a plurality of positions corresponding to each minute for 10 minutes.
And the computer equipment compares the acquired multipoint temperature information with a preset temperature threshold interval to obtain a plurality of comparison results. Specifically, the computer device compares the temperature information of each measurement point with a preset temperature threshold interval to obtain a comparison result of each measurement point. The preset temperature threshold interval can be the normal working temperature of the nuclear power capacitor. Because the normal working temperature of each measuring point is different, the temperature threshold interval can be set according to the normal working temperature corresponding to each measuring point. The setting manner of the temperature threshold value interval is not limited. The preset temperature threshold interval comprises a minimum temperature value and a maximum temperature value. The comparison result may be a difference between the temperature information and the minimum temperature value, or may be a difference between the temperature information and the maximum temperature value.
When the computer equipment acquires the temperature information in the preset time period, comparing the temperature information corresponding to each measuring point at each moment with a preset temperature threshold interval to obtain a comparison result corresponding to each measuring point at each moment.
The computer device judges whether the comparison results are within a preset temperature threshold interval. And if the comparison result is not within the preset temperature threshold range, taking the comparison result as a target comparison result. The target comparison result is a comparison result which is not within the preset temperature threshold range and represents temperature information which needs to be subjected to temperature adjustment. And the computer equipment retrieves according to the historical adjustment information through the big data platform to obtain the corrected temperature information to be verified. The computer equipment can verify the corrected temperature information to be verified, which is obtained for the first time, through an expert system. The expert system comprises two parts: and part is the historical adjustment information that passed the verification. And the other part is confirmed by an expert terminal. When the temperature information to be verified and corrected cannot be verified according to the history adjusting information passing the verification, the temperature information to be verified and corrected can be sent to the expert terminal, the temperature information to be verified and corrected can be confirmed through the expert terminal, and a verification result sent by the expert terminal can be obtained. And the computer equipment takes the corrected temperature information after passing the verification as the corrected temperature information corresponding to the target comparison result. And the computer equipment adjusts the corresponding target comparison result according to the corrected temperature information, so that the temperature in the nuclear power container can be automatically adjusted. Specifically, the computer device may send the corrected temperature information to the temperature adjustment device, so that the temperature adjustment device adjusts the temperature of the nuclear power capacitor according to the corrected temperature information. The computer device obtains the adjusted temperature information output by the temperature measuring device.
In this embodiment, the computer device obtains the multi-point temperature information corresponding to the inside of the nuclear power container through the plurality of fiber bragg grating sensors, and can measure the temperature of a plurality of main parts inside the nuclear power container, so as to realize comprehensive monitoring. And the computer equipment compares the multipoint temperature information with a preset temperature threshold interval, and when the multipoint temperature information meets a preset adjusting condition, the corrected temperature information is obtained through analysis of a big data platform, so that the temperature of the nuclear power container is adjusted. The temperature in the nuclear power container can be adjusted in time when the temperature information is abnormal, and the temperature in the nuclear power container is controlled within a safety range, so that safety accidents are reduced.
In one embodiment, as shown in fig. 2, the step of obtaining the corrected temperature information corresponding to the target comparison result through the big data platform analysis includes:

And the computer equipment acquires the target comparison result, and searches in the historical adjustment information according to the target comparison result through the big data platform to obtain the similar historical adjustment information. There may be a plurality of historical adjustment information of the same type. And the computer equipment analyzes the retrieved historical adjustment information of the same type through the big data platform to obtain the correction probability of the historical adjustment information of the same type. The computer equipment selects the same type of historical adjustment information with the maximum correction probability as initial adjustment information, namely corrected temperature information to be verified.
The computer device may verify the initial adjustment information in a number of ways. The computer equipment can perform a double check on the initial adjustment information according to the historical adjustment information passing the historical verification in the expert system. The computer device may also confirm the initial adjustment information through an expert terminal in the expert system. And when the initial adjustment information passes the verification, the final corrected temperature information is obtained. And the server adjusts the corresponding target comparison result according to the final correction adjustment information.
In this embodiment, the computer device retrieves the corrected temperature information to be verified from the historical adjustment information through the big data platform, and verifies the corrected temperature information to be verified to obtain the corrected temperature information corresponding to the target comparison result. The correction temperature information corresponding to the multipoint temperature information can be identified according to historical adjustment experience, so that a reasonable basis exists for the correction temperature information, and the accuracy of temperature adjustment of the nuclear power container is further improved.

The computer device sends the corrected temperature information to the temperature adjustment device. The corrected temperature information refers to an appropriate temperature within a safe temperature range of a target comparison result satisfying a preset regulation condition. The temperature adjusting device adjusts the flow area between the valve flap and the valve seat of the valve according to the corrected temperature information. And a pipeline is arranged outside the nuclear power container and communicated with the nuclear power container. When the flow area changes, the heat exchange rate of the medium in the pipeline and the medium in the nuclear capacitor changes, so that the temperature in the nuclear capacitor is adjusted, and the adjusted temperature information is output.
The computer equipment sends the corrected temperature information to the temperature adjusting device, so that the temperature adjusting device adjusts the flow area between the valve clack and the valve seat of the valve, and the temperature information in the nuclear power container can be adjusted in time.
In one embodiment, determining the target comparison result satisfying the preset adjustment condition among the plurality of comparison results includes: searching a comparison result which is not in a preset temperature threshold value interval in the plurality of comparison results; and taking the comparison result which is not in the preset temperature threshold interval as a target comparison result meeting the preset regulation condition.
After the computer equipment obtains the comparison result, whether the comparison result is within a preset temperature threshold value interval is judged. For example, when the difference between the temperature information in the comparison result and the minimum temperature value in the preset temperature threshold interval is less than zero, that is, the temperature information is less than the minimum temperature value in the preset temperature threshold interval, the comparison result is taken as the target comparison result. And when the difference value between the temperature information in the comparison result and the maximum temperature value of the preset temperature threshold interval is greater than zero, namely the temperature information is greater than the maximum temperature value of the preset temperature threshold interval, taking the comparison result as a target comparison result.
The computer equipment compares a plurality of comparison results with a preset temperature threshold interval by setting the temperature threshold interval, and can monitor abnormal temperature information in the nuclear power container.

The computer equipment can also set a preset alarm temperature, compare the multipoint temperature information with the preset alarm temperature, and generate corresponding alarm information when the difference value between the multipoint temperature information and the preset alarm temperature is larger than the error range. The corresponding alarm information can be generated under the condition that the temperature of the nuclear power container is abnormal seriously, so that monitoring personnel can adjust the temperature in time.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
