There is a lack of integrated, multi-parameter, and high-speed comprehensive electromagnetic environment sensing and control tools. Therefore, there is no electromagnetic environment measurement and control software platform capable of completing the acquisition, analysis, control, and early warning of a series of parameters, including electromagnetic radiation, conduction, electric field, magnetic field, frequency domain, time domain, voltage, and current.

[0075] The technical solutions of this disclosure and how they solve the above-mentioned problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0076] This invention can identify abnormalities in the electromagnetic environment within a nuclear power plant in advance, alerting staff to take proactive and effective measures to reduce the risks to equipment safety caused by changes in the electromagnetic environment and ensure the normal operation of all functions during the nuclear power unit's operation.

This includes comprehensive sensing and measurement of typical operating electromagnetic environments such as electromagnetic frequency, intensity, time domain, frequency domain, and spatial domain. Furthermore, it uses a measurement and control software platform to record electromagnetic environment characteristic data during the nuclear power unit's operation phase over a long period, providing support for research on the electromagnetic environment characteristics of nuclear power units. Statistical analysis of a large amount of electromagnetic data from nuclear power units can provide strong support for research on the development of new nuclear power units, the electromagnetic environment characteristics of nuclear power units, electromagnetic emissions from instrumentation and control equipment, and electromagnetic immunity characteristics.

The frequency-domain sensors include four types: far-field ultra-wideband near-field electric field probes, ultra-wideband near-field magnetic field probes, ultra-wideband high-sensitivity antennas, and current probes, with one or more of each type. The time-domain sensors include one or more voltage probes.

[0086] The radio frequency matrix switch is connected to each sensor via radio frequency cables or photoelectric transmission channels. It is used to sequentially select the transmission signals of each sensor and transmit them to a real-time spectrum analyzer. The photoelectric transmission channel includes an electro-optical converter located at the sensor and connected to the sensor, a photoelectric converter located at the radio frequency matrix switch and connected to one input of the radio frequency matrix switch, and a switch connecting the electro-optical converter and the photoelectric converter.

At the same time, a file size setting function is provided to set the file size according to two parameters: file size or test data duration.

[0102] The first status statistics unit is used to statistically display various states of the comprehensive risk index, single test duration, cycle period, and electromagnetic compatibility status. The various states of electromagnetic compatibility status include red, yellow, and green states. It also calls the functions in the data statistical analysis module to display the overall electromagnetic status of the nuclear power unit.

[0103] Among the various electromagnetic compatibility states, red, yellow, and green represent alarm, warning, and safety states, respectively. These states are determined by the alarm alert level set in the alarm parameter setting unit, and are generally determined based on the environment and design standards of the equipment.

[0104] Measurement data display module 13 is used to display measurement data of the measurement and control hardware system;

[0105] like Figure 5 As shown in the embodiments of this application, the measurement and data display module 13 can respectively complete the measurement and data display of five types of sensors: ultra-wideband near-field electric field probe, ultra-wideband near-field magnetic field probe, ultra-wideband high-sensitivity antenna, current probe, and voltage probe. The ultra-wideband near-field electric field probe has a maximum sweep bandwidth of 18 GHz and can complete near-field electric field signal testing and display, showing the measurement results in the form of a frequency domain graph.

After calculating the cumulative alarm-free time ratio, the current continuous test fault-free time ratio of the system needs to be displayed, calculated as a percentage, with a maximum of 100% and a minimum of 0%. This ratio is equal to the cumulative fault-free time divided by the cumulative test duration.

[0111] In the alarm status analysis unit, the number of red alarms is analyzed, which is the number of times the red alarm limit is exceeded during the continuous operation of the system. The maximum number of times is 1 and the minimum number is 0 in each test cycle, and the count is continuously accumulated.
