[0071] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0072] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0074] The embodiments of the present application provide a nuclear power plant wireless communication method, device, electronic device and storage medium, aiming to reduce the damage rate of nuclear power wireless communication equipment in a reactor building.

[0075] The nuclear power plant wireless communication method, device, electronic device and storage medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the nuclear power plant wireless communication device in the embodiments of the present application is described.

[0076] Figure 1 is a schematic diagram of the structure of a wireless communication device for a nuclear power plant provided in an embodiment of the present application, Figure 1 The devices may include but are not limited to:

[0077] Signal source 101, signal source 101 is used to obtain nuclear power wireless communication signals, and signal source 101 is set outside the target plant 100. Signal source 101 refers to communication base stations and other equipment, including POE (Power over Ethernet) switches, wireless routers, wireless bridges, etc., which are used to obtain and transmit wireless communication signals. Among them, the target plant 100 is provided with a protective structure to block the propagation of radiation, which can prevent the radiation in the target plant 100 from propagating to the environment outside the target plant 100.

[0078] The first penetration member 102 is disposed in the protective structure of the target plant 100 and is used to connect the environment inside and outside the target plant 100 to ensure that the nuclear power wireless communication signal can be transmitted between the inside and outside of the target plant 100.

[0079] The bidirectional signal amplifier 103 is arranged in the target plant 100 and is electrically connected to the signal source 101 outside the target plant 100 through a penetration piece. It is used to enhance the nuclear power wireless communication signal transmitted to the target plant 100 to obtain the target output signal, enhance the received plant wireless communication signal, and obtain the target incoming signal.

[0080] The nuclear power wireless communication signal and the plant wireless communication signal are distinguished only in the propagation direction. The nuclear power wireless communication signal is a wireless communication signal acquired by the signal source 101 and transmitted to the inside of the target plant 100, while the plant wireless communication signal is a wireless communication signal transmitted from the inside of the target plant 100 and can be transmitted to the signal source 101 to be transmitted outside the target plant 100. In essence, they are all wireless communication signals in the nuclear power plant wireless communication device provided in the embodiment of the present application.

[0081] Antenna 104 , which is electrically connected to the bidirectional signal amplifier 103 , is used to transmit a target output signal to the target plant 100 and receive a plant wireless communication signal in the target plant 100 .

[0082] Considering that the signal source 101 is set outside the reactor building, the loss of the wireless communication signal during transmission will be relatively large, which will affect the signal strength. Therefore, a bidirectional signal amplifier 103 is set between the signal source 101 and the antenna 104 to enhance the transmitted wireless communication signal.

[0083] Reference Figure 2 In some embodiments, the bidirectional signal amplifier 103 is provided with an amplifier power supply 105 , which is disposed outside the target plant 100 and is electrically connected to the bidirectional signal amplifier 103 in the target plant 100 through a second penetration piece 106 for supplying power to the bidirectional signal amplifier 103 .

[0084] Since the bidirectional signal amplifier 103 usually needs independent power supply to work properly, it is necessary to configure an amplifier power supply 105. The amplifier power supply 105, like the signal source 101, is a device with power supply. The electronic components contained in such devices are easily affected by radiation, resulting in the performance of the electronic components being degraded or not working properly, thereby increasing the damage rate of the device.

[0085] In some embodiments, the housing of the bidirectional signal amplifier 103 is made of stainless steel, and the electronic components inside the bidirectional signal amplifier 103 are wrapped with metal tantalum sheets, thereby resisting the radiation influence inside the radiation reactor plant and ensuring the service life of the bidirectional signal amplifier.

[0086] Figure 3 It is a structural schematic diagram of the bidirectional signal amplifier 103 provided in an embodiment of the present application. The bidirectional signal amplifier 103 includes a first input-output module 201, a first mixer 202, a first crystal oscillator 203, a first power amplifier 204, a first filter 205, a second input-output module 206, a second power amplifier 207, a second mixer 208, a second crystal oscillator 209, a second filter 210 and a control circuit 211.

[0087] Among them, the first input-output module 201 is used to input the nuclear power wireless communication signal and output the target incoming signal. The first crystal oscillator 203 is electrically connected to the first mixer 202, and is used to provide the first reference frequency to the first mixer 202. The first mixer 202 is electrically connected to the first input-output module 201, and is used to perform frequency conversion processing on the input nuclear power wireless communication signal according to the first reference frequency provided by the first crystal oscillator 203, so as to obtain a first processed signal adapted to the communication frequency in the target plant 100. The first power amplifier 204 is electrically connected to the first mixer 202, and is used to perform signal amplification processing on the first processed signal, increase the power of the first processed signal, enhance the signal strength of the first processed signal, and obtain a first enhanced signal. The first filter 205 is electrically connected to the first power amplifier 204, and is used to perform noise filtering processing on the first enhanced signal to obtain a target output signal.

[0088] The second input-output module 206 is electrically connected to the first filter 205, and is used to output the target output signal and input the factory wireless communication signal. The second power amplifier 207 is electrically connected to the second input-output module 206, and is used to amplify the input factory wireless communication signal, enhance the signal strength of the factory wireless communication signal, and obtain a second enhanced signal. The second crystal oscillator 209 is electrically connected to the second mixer 208, and is used to provide the second reference frequency to the second mixer 208. The second mixer 208 is electrically connected to the second power amplifier 207, and is used to perform frequency conversion processing on the second enhanced signal according to the second reference frequency provided by the second crystal oscillator 209, and obtain a second processed signal. The second filter 210 is electrically connected to the second mixer 208, and is used to perform noise filtering processing on the second processed signal to obtain a target incoming signal.

[0089] The control circuit 211 is used to connect to the amplifier power supply 105, and is respectively connected to the first mixer 202, the first power amplifier 204, the first filter 205, the second power amplifier 207, the second mixer 208, and the second filter 210 to supply power.

[0090] Reference Figure 4 In some embodiments, a coupler 301 is further included between the bidirectional signal amplifier 103 and the antenna 104. The coupler 301 is disposed in the target plant 100 and is electrically connected to the bidirectional signal amplifier 103 for limiting the transmission power of the target output signal to obtain a power limiting signal.

[0091] This is because in nuclear power plants, the power of wireless communication equipment needs to be controlled within a certain range to avoid interference with nuclear radiation monitoring equipment and to ensure that the communication equipment itself will not be damaged by radiation. On the other hand, the power of wireless communication signals needs to match the electromagnetic compatibility of other electronic equipment in the nuclear power plant to prevent mutual interference, so it is necessary to limit the transmission power of the target output signal.

[0092] In some embodiments, a power divider 302 is also included between the bidirectional signal amplifier 103 and the antenna 104. The power divider 302 is arranged in the target plant 100 and is electrically connected to the bidirectional signal amplifier 103 for distributing the target output signal to multiple nuclear power signal transmission paths, each of which is equipped with an antenna 104.

[0093] In order to cover the target output signal to the entire target plant 100, multiple antennas 104 need to be set in the target plant 100 to broadcast the target output signal. Therefore, the target output signal can be equally divided or distributed to multiple nuclear power signal transmission paths in a certain proportion by the power divider 302, and an antenna 104 is configured on each nuclear power signal transmission path.

[0094] It should be noted that the coupler and power divider are set based on the environmental requirements of the target plant. If the target plant is small, the wireless communication signal released by one antenna can cover the entire target plant, so there is no need for a power divider to distribute the target output signal to multiple nuclear power signal transmission paths for output at multiple antennas. If the power of the wireless communication equipment does not affect the nuclear radiation monitoring equipment, then the coupler can also be omitted.

[0095] In some embodiments, a coupler 301 and a power divider 302 are included between the bidirectional signal amplifier 103 and the antenna 104. The material of the feeder for transmitting signals in the target plant is copper, and the material of the coupler, the power divider and the antenna is copper. Each of the components described above is connected through a feeder to achieve signal transmission. When the antenna receives the plant wireless communication signal in the target plant, the coupler and the power divider will not process the plant wireless communication signal, and will only be regarded as a channel for transmitting the signal.

[0096] It should be noted that the coupler 301 and the power divider 302 are passive devices. They do not rely on an external power supply to work, but transmit and distribute signals through the energy of the input signal, and are therefore less affected by radiation.

[0097] However, in view of the particularity of the reactor building environment, when the internal environment of the reactor building is at high temperature, aluminum-containing equipment is easy to react with the spray liquid in the reactor building to precipitate hydrogen. When hydrogen accumulates to a certain extent in the reactor building, it may burn, explode or even explode in the presence of an ignition source, threatening the integrity of the reactor and causing the release of radioactive gases in the reactor building. Therefore, when selecting materials for couplers, power dividers, antennas and feeders arranged in the reactor building, their adaptability to the environment is taken into consideration, and couplers, power dividers, antennas and feeders are made of all-copper material.

[0098] See also Figure 5 In some embodiments, the nuclear power plant wireless communication device is provided with a coupler 301, a power divider 302, an amplifier power supply 105, and a second penetration piece 106, so that the operation of the bidirectional signal amplifier 103 is not affected by the radiation inside the reactor building, and the metal tantalum sheet is used to wrap the bidirectional signal amplifier 103 to ensure the service life of the bidirectional signal amplifier 103. On the other hand, the coupler 301 and the power divider 302 can limit the transmission power of the target output signal and distribute it to multiple nuclear power signal transmission paths, thereby avoiding signal interference and ensuring that the target output signal covers the entire target building.

[0099] Figure 6 is a flow chart of a nuclear power plant wireless communication method provided in an embodiment of the present application, Figure 6 The method may include but is not limited to steps S601 to S604.

[0100] Step S601, a signal source is used to obtain a nuclear power wireless communication signal, wherein the signal source is set outside a target plant, and the target plant is provided with a protective structure for blocking radiation propagation;

[0101] Step S602, the first penetration piece is used to connect the environment inside and outside the target plant to ensure that the nuclear power wireless communication signal can be transmitted between the inside and outside of the target plant;

[0102] Step S603, the bidirectional signal amplifier is used to enhance the nuclear power wireless communication signal transmitted to the target plant to obtain the target output signal, and enhance the received plant wireless communication signal to obtain the target incoming signal;

[0103] Step S604: the antenna is used to transmit a target output signal to a target factory building and receive a factory building wireless communication signal in the target factory building.

[0104] In the steps S601 to S604 shown in the embodiment of the present application, a signal source is set outside the target plant to obtain a nuclear power wireless communication signal, a first penetration is set on a protective structure of the target plant that can block radiation propagation, and the communication between the signal source outside the target plant and the two-way signal amplifier in the target plant is realized through the first penetration, and the nuclear power wireless communication signal transmitted to the target plant is enhanced through the two-way signal amplifier, and the plant wireless communication signal received by the antenna is enhanced. It can be seen that the present application avoids the signal source equipment from being affected by radiation in the target plant by setting the signal source outside the reactor plant and communicating with the two-way signal amplifier and other equipment in the plant through the first penetration, thereby reducing the damage rate of nuclear power wireless communication equipment in the reactor plant.

[0105] In step S601 of some embodiments, the signal source is set outside the target plant to prevent the signal source from being affected by radiation. The target plant is equipped with a protective structure that blocks the propagation of radiation, which can protect the signal source from the influence of radiation, ensure that the signal source can safely send signals to the inside of the plant, and prevent radiation from polluting the environment.

[0106] In step S602 of some embodiments, the function of the first penetration component is to connect the environment inside and outside the target plant, allowing nuclear power wireless communication signals to be transmitted between the inside and outside of the plant.

[0107] In step S603 of some embodiments, the bidirectional signal amplifier not only enhances the nuclear power wireless communication signal transmitted to the target plant to obtain the target output signal, but also enhances the received plant wireless communication signal to obtain the target incoming signal. The bidirectional enhanced signal ensures the strength and clarity of the signal during transmission, so as to maintain the reliability of communication in a complex radiation environment.

[0108] In step S604 of some embodiments, the antenna is used to transmit a target output signal to the target plant and receive a plant wireless communication signal from the plant. The design and position of the antenna have a direct impact on the signal coverage and communication quality. Multiple antennas can be set up at different locations of the target plant to achieve maximum signal coverage, ensuring effective signal propagation inside the target plant, while also being able to receive plant wireless communication signals from inside the plant.

[0109] See also Figure 7 In some embodiments, the bidirectional signal amplifier includes a first input-output module, a first mixer, a first crystal oscillator, a first power amplifier, and a first filter. Step S603 may include but is not limited to steps S701 to S704:

[0110] Step S701, generating a first reference frequency by a first crystal oscillator;

[0111] Step S702, the first mixer performs frequency conversion processing on the nuclear power wireless communication signal input through the first input and output module according to the first reference frequency to obtain a first processed signal;

[0112] Step S703: the first power amplifier performs signal amplification processing on the first processed signal to obtain a first enhanced signal;

[0113] Step S704: The first filter performs noise filtering on the first enhanced signal to obtain a target output signal.

[0114] In steps S701 to S702 of some embodiments, the first crystal oscillator is responsible for generating a first reference frequency so that the first mixer uses the reference frequency provided by the first crystal oscillator to perform frequency conversion processing on the nuclear power wireless communication signal input through the first input and output module, so that the signal can adapt to the requirements of the wireless communication system and convert the signal into a frequency suitable for transmission to obtain a first processed signal.

[0115] In step S703 of some embodiments, the first power amplifier performs signal amplification processing on the first processed signal, thereby ensuring that the signal has sufficient strength during transmission to overcome the loss of the wireless communication signal during transmission and obtain a first enhanced signal.

[0116] In step S704 of some embodiments, the first filter performs noise filtering processing on the first enhanced signal to remove noise and interference that affect signal quality, and finally obtains a target output signal.

[0117] Through steps S701 to S704, the nuclear power wireless communication signal is effectively enhanced and filtered, thereby ensuring the stability and reliability of signal transmission.

[0118] See also Figure 8 In some embodiments, the bidirectional signal amplifier further includes a second input-output module, a second mixer, a second crystal oscillator, a second power amplifier, and a second filter. Step S603 may include but is not limited to steps S801 to S804:

[0119] Step S801, the second power amplifier performs signal amplification processing on the factory building wireless communication signal input by the second input and output module to obtain a second enhanced signal;

[0120] Step S802, generating a second reference frequency by a second crystal oscillator;

[0121] Step S803, the second mixer performs frequency conversion processing on the second enhanced signal according to the second reference frequency provided by the second crystal oscillator to obtain a second processed signal;

[0122] Step S804: The second filter performs noise filtering on the second processed signal to obtain a target incoming signal.

[0123] In step S801 to step S804 of some embodiments, the processing process of this step is the same as step S701 to step S704, except that the second input-output module, the second mixer, the second crystal oscillator, the second power amplifier, and the second filter are described here. In order to save space, the same processing parts are not repeated here. The difference is that the wireless communication signal of the factory building is first amplified to obtain the second enhanced signal. This is because the wireless communication signal of the factory building may be lost due to the complex environment in the target factory building and become very weak. Therefore, it is necessary to first perform signal amplification to obtain the second enhanced signal, and then perform frequency conversion and noise filtering to obtain the target incoming signal.

[0124] Through step S801 to step S804, the factory wireless communication signal is effectively enhanced and filtered, thereby ensuring the stability and reliability of signal transmission.
