For safety of the nuclear power plant and the surrounding environment, in the internal space of the nuclear island building, there are usually disposed monitoring instruments, such as radiation dose sensors, hydrogen concentration sensors, aerosol detectors, etc., which monitor physical parameters of the internal space of the nuclear power plant building, such as radiation intensity, hydrogen concentration, aerosol number concentration, mass concentration, etc., so as to help the nuclear power plant operator to grasp the status of the monitoring parameters inside the nuclear island building of the nuclear power plant and to give an alarm when a nuclear leak may occur.

At present, the monitoring meters used in the design of the nuclear power plant are basically wired meters which are powered by a wired line and perform communication transmission. The advantage of these wired meters is that data and power transmission is reliable.

However, the space layout inside the nuclear island plant of the nuclear power plant is complex, the arrangement position and the number of the wired monitoring instruments are limited by the wiring, and the cost and the construction amount of the instrument wiring are high.

Compared with a wired instrument, the wireless monitor meter reduces the limitation and cost caused by meter wiring, so that the arrangement and installation are more flexible, but if the wireless monitor meter is applied to a nuclear island factory building of a nuclear power station, some problems exist in meter maintenance.

The time interval of refueling and maintenance of the existing pressurized water reactor nuclear power station is mostly one to two years, maintenance personnel cannot enter a nuclear island plant to maintain the wireless monitoring instrument in the period, and only in the shutdown refueling or maintenance period of the nuclear power station, the nuclear power station maintenance personnel can possibly enter the nuclear island plant to maintain and replace the battery of the wireless monitoring instrument, so that the battery reliability and the cruising ability of the wireless monitoring instrument are challenged.

Be applied to the nuclear power station design through wireless monitoring instrument, because wireless monitoring instrument has very big flexibility in arranging, can arrange it in the narrow and small and difficult position department of wiring of nuclear power station nuclear island factory building inner space, reduce the construction volume of the cost of instrument wiring simultaneously. Especially for monitoring instruments such as radiation dose sensors, hydrogen concentration sensors and aerosol detectors, wherein monitoring targets are distributed in the whole space range in a nuclear island plant, instrument lines are omitted, the number of the monitoring instruments is increased more easily, and therefore the density and the range of arrangement of the monitoring instruments are increased.

The battery of the target wireless monitoring instrument does not need to be replaced within a long operating life of the nuclear power station, so that the workload of nuclear power station maintenance personnel is greatly reduced. Meanwhile, although the maintenance work of the wireless charging stations is increased by the maintenance personnel of the nuclear power station, one wireless charging station can charge a plurality of target wireless monitoring instruments, so that the number of the wireless charging stations to be maintained is usually far less than that of the target wireless monitoring instruments, and in addition, the wireless charging stations are reasonably arranged at positions in the nuclear island plant where the personnel can easily reach and the ionizing radiation intensity is relatively low, so that the workload and the ionizing radiation dose of the maintenance personnel of the nuclear power station can be further reduced.

Next, a charging system for a nuclear power plant wireless monitoring instrument in the present exemplary embodiment will be further described.

In the embodiment of the application, the control device is respectively connected with the wireless charging station and the target wireless monitoring instrument in a wireless manner; the control device controls the wireless charging receiver to adjust the configuration of the antenna array, so that the target wireless monitoring instrument is controlled to receive a wireless wave beam with preset power and preset time; the control device controls the wireless charging station to emit the radio wave beam to the direction of the target wireless monitoring instrument, the control device controls the wireless charging receiver to adjust the configuration of the antenna array, so that the target wireless monitoring instrument is controlled to receive the radio wave beam with preset power and preset time, and the wireless charging receiver converts the energy of the radio wave beam into electric energy; the control device controls the target wireless monitoring instrument to adjust the frequency of measuring the physical quantity and the frequency of transmitting the measurement result.

In one implementation, the control device is capable of receiving signals from the wireless charging station and the wireless monitoring meter and wirelessly transmitting control signals to the wireless charging station and the wireless monitoring meter.

In a specific implementation, the control device may control the target wireless monitoring instrument to adjust a frequency of measuring the physical quantity and a frequency of transmitting a measurement result according to an operation state of the nuclear power plant, and simultaneously control the wireless charging station to transmit a radio beam to the target wireless monitoring instrument at a corresponding preset power and preset time. Specifically, when the nuclear power plant is in a dynamic working condition such as a reactor start-up process, a reactor shutdown process, a power lifting process, or the like, or when the nuclear power plant is in an abnormal operating working condition (for example, in an accident working condition), the control device controls the target wireless monitoring instrument to measure the physical quantity at a higher frequency (for example, a measurement period of 1 second to several seconds) and transmit the measurement result, so that a higher monitoring density is achieved during a critical operating working condition of the nuclear power plant, and at this time, the target wireless monitoring instrument consumes a larger amount of power, so that the control device controls the wireless charging station to transmit a radio beam to the target wireless monitoring instrument at a higher preset power or for a longer preset time. When the nuclear power plant is in a stable full power operation condition or a hot standby condition, the control device controls the target wireless monitoring instrument to measure the physical quantity at a medium frequency (a measurement period is several seconds to several tens of seconds) and transmit the measurement result, and controls the wireless charging station to transmit the radio beam to the target wireless monitoring instrument at a medium preset power or a medium preset time. In addition, when the nuclear power plant is in an operating condition such as normal cold shut down, the control device controls the target wireless monitoring instrument to measure the physical quantity at a low frequency (the measurement period is 1 minute or more) and transmit the measurement result, and controls the wireless charging station to transmit the radio beam to the target wireless monitoring instrument at a low preset power or for a short preset time. Through the configuration, the monitoring effect of the target wireless monitoring instrument under the key working condition of the nuclear power station can be ensured, the power utilization efficiency of the target wireless monitoring instrument is improved, and the charging times and the battery loss are reduced. In a further specific implementation, the control device may further control the target wireless monitoring instrument to adjust the frequency of measuring the physical quantity and the frequency of transmitting the measurement result according to the measurement result transmitted by the target wireless monitoring instrument to the control device, and simultaneously control the wireless charging station to transmit the radio beam to the target wireless monitoring instrument at the corresponding preset power and preset time. Specifically, when the measurement result transmitted from the target wireless monitoring meter to the control device changes smoothly, the control device controls the target wireless monitoring meter to measure the physical quantity at a lower frequency and transmit the measurement result, and controls the wireless charging station to transmit the radio beam to the target wireless monitoring meter at a lower preset power or a shorter preset time. And when the measurement result transmitted to the control device by the target wireless monitoring instrument indicates that environmental parameters such as ionizing radiation dose, aerosol concentration or hydrogen concentration are abnormally increased, the control device controls the target wireless monitoring instrument to measure physical quantity at a higher frequency and transmit the measurement result, and controls the wireless charging station to transmit a radio beam to the target wireless monitoring instrument at a higher preset power or a longer preset time. Through the configuration, when abnormal working conditions of the nuclear power station occur, the monitoring density of the target wireless monitoring instrument can be guaranteed, the power utilization efficiency of the target wireless monitoring instrument is improved, and the charging times and the battery loss are reduced.

In the embodiment of the application, the control device is wirelessly connected with the wireless gateway; the wireless gateway is respectively in wireless connection with the wireless charging station and the target wireless monitoring instrument; the control device respectively transmits control signals to the wireless charging station and the target wireless monitoring instrument through the wireless gateway, so that the control device controls the wireless charging station to emit the radio wave beam with preset power and preset time to the direction of the target wireless monitoring instrument; the control device controls the wireless charging receiver to adjust the configuration of the antenna array through a control signal of the wireless gateway, so that the target wireless monitoring instrument is controlled to receive a wireless beam with preset power and preset time; the control device controls the target wireless monitoring instrument to adjust the frequency of the measured physical quantity and the frequency of the transmitted measurement result through the control signal of the wireless gateway.

In the embodiment of the application, the target wireless monitoring instrument is arranged in a specific area of the nuclear power station; wherein the specific region includes a region where the ionizing radiation dose is not less than a preset amount and a region where it is difficult for an operator to perform work.

In a specific implementation, the multiple devices in the nuclear island building are radioactive sources, and the target wireless monitoring instrument may need to be arranged in a high radiation area in the nuclear island building to monitor radiation dose, hydrogen concentration, aerosol concentration and the like in a critical area. And after entering the nuclear island plant, maintenance personnel need to be as far as possible away from the radiation source, so that the safety problem of the maintenance personnel is solved by the target wireless monitoring instrument. In addition, the specific area can also be a position which can be reached by maintenance personnel by additional equipment, such as a higher position or a position with narrow space.

In a particular implementation, the present application may include a plurality of target wireless monitor meters and at least one wireless charging station. Each target wireless monitoring instrument is used to measure a specific physical quantity, such as hydrogen concentration, aerosol number concentration, radiation dose, etc., continuously or with a specific time period. The method is particularly suitable for a network formed by wireless instruments for online monitoring in the space of a nuclear island of a nuclear power station, such as a network formed by a radiation dose sensor, a hydrogen concentration sensor, an aerosol detector and the like.

It should be noted that, because the radiation dose of the nuclear island plant of the nuclear power plant is high during normal operation, a maintainer cannot enter the nuclear island plant, and cannot maintain and replace the target wireless monitoring instrument, and only during shutdown and refueling of the nuclear power plant or during maintenance, the maintainer of the nuclear power plant may enter the nuclear island plant to maintain and replace the target wireless monitoring instrument. If the target wireless monitoring instrument does not have wireless charging capability, its instrument battery must supply power to the target wireless monitoring instrument for at least one refuel service period, and one refuel service period is one to two years, which requires each target wireless monitoring instrument to be equipped with a large capacity battery and limits the energy consumption of the target wireless monitoring instrument. In addition, since it is necessary to replace batteries for a large number of target wireless monitoring instruments with flexible installation positions during each shutdown refueling maintenance of the nuclear power plant, the workload of the nuclear power plant maintenance personnel will be significantly increased. Therefore, the wireless charging system is designed for the target wireless monitoring instrument in the nuclear island plant of the nuclear power station, so that the requirements on the capacity of the instrument battery and the energy consumption of the instrument are reduced, and the times of replacing the battery for the target wireless monitoring instrument are reduced. A wireless charging station is arranged in the wireless charging system, and the wireless charging station transmits energy to a plurality of target wireless monitoring meters in a wireless charging range of the wireless charging station in a wireless wave beam mode so as to charge a meter battery of the target wireless monitoring meters.

In an embodiment of the present application, the target wireless monitoring instrument includes a wireless charging receiver; the control device controls the wireless charging receiver to adjust the configuration of the antenna array, so that the target wireless monitoring instrument is controlled to receive the wireless wave beam with preset power and preset time. Since the energy of the radio beam is continuously attenuated with the increase of the transmission distance, the wireless charging station has a certain charging range, the wireless charging station can only carry out effective wireless charging on the wireless monitoring instrument in the charging range, and the target wireless monitoring instrument is covered by the charging ranges of at least two wireless charging stations. As an example, each of the target wireless monitoring meters does not have a wired connection to an external power source and is within wireless charging range of at least one wireless charging station. Optionally, by redundantly configuring a plurality of wireless charging stations and arranging the locations of the wireless charging stations such that each target wireless monitoring instrument is within the charging range of at least two wireless charging stations, the wireless charging receiver of each target wireless monitoring instrument can adjust the receiving antenna array configuration by the control device to receive a radio beam from any one of the wireless charging stations. Therefore, even under the condition that a single wireless charging station has a fault, the power supply of any target wireless monitoring instrument in the charging network cannot be influenced, and the reliability of the system is improved.

In a further embodiment, the target wireless monitor meter is covered by the charging range of at least two of the wireless charging stations, and the power supply of the wireless charging stations is a battery. The wireless charging station wirelessly transmits a signal indicating the current electric quantity of the storage battery of the wireless charging station to the control device, and the control device controls the wireless charging device with the higher current electric quantity of the storage battery to transmit a radio beam with preset power and preset time to the target wireless monitoring instrument, so that uneven consumption of the electric quantity of the storage battery of the wireless charging station is avoided, and the working time of the wireless charging station is prolonged.

In an embodiment of the present application, the second wireless signal transceiver receives the control signal from the control device through the wireless gateway and transmits the control signal to the second processing circuit, and the second processing circuit processes the control signal; the second processing circuit controls the wireless charging receiver to adjust the configuration of the antenna array according to the control signal, so that the target wireless monitoring instrument receives the radio wave beam with preset power and preset time; the second processing circuit controls the sensing device to measure the frequency of the physical quantity according to the control signal and controls the second wireless signal transceiver to adjust the frequency of the transmission measurement result.

As an example, the target wireless monitoring meter includes a second wireless signal transceiver, and the second wireless signal transceiver receives the control signal transmitted from the control device, so as to control the wireless charging receiver to receive the radio beam.

As an example, when the target wireless monitoring instrument is an internet of things instrument, the second wireless signal transceiver may communicate with a wireless gateway or a relay station by using an internet of things communication protocol such as a narrowband internet of things.

As one example, each target wireless monitoring meter includes one or more sensing devices, a second processing circuit, at least one second wireless signal transceiver, a meter battery pack, a second power converter, and one or more wireless charging receivers. The sensing device of the target wireless monitoring instrument is used to measure at least one physical quantity, such as hydrogen concentration, aerosol number concentration, radiation dose, etc., continuously or with a specific time period and to generate a corresponding analog measurement signal. The second processing circuit of the target wireless monitoring meter processes the analog measurement signal generated by the sensing device and converts it to a digital signal of suitable form. The second processing circuit may be a mode-to-electrical conversion circuit.

The modulation circuit modulates information to be transmitted onto a carrier signal, and then the power amplification circuit amplifies the power of an output signal of the modulation circuit.

As one example, each target wireless monitoring meter in the wireless charging system is configured with a wireless charging receiver and a second power converter. The wireless charging receiver comprises a receiving antenna array and a radio frequency receiving circuit, and is configured to receive a radio beam wirelessly transmitted from the wireless charging station and convert the radio beam into alternating current. The wireless charging receiver is connected to the instrument battery via a second electric energy converter, and the high-frequency current received and converted by the wireless charging receiver is converted into direct current suitable for charging the instrument battery by the second electric energy converter and is used for charging the instrument battery pack of the target wireless monitoring instrument. The second power converter may be implemented with an AC-DC conversion circuit (Alternating current-Direct current), such as a diode rectifier circuit or an electronic switch rectifier circuit.

The battery management circuit switches between the meter battery and the backup battery according to the capacity fade of the meter battery.

As an example, when the chargeable capacity of the meter battery decays below a preset threshold, switching to the backup battery by the battery management circuit; when the chargeable capacity of the backup battery decays to below a preset threshold, switching to another backup battery by the battery management circuit.

As an example, the instrument battery and the backup battery of the target wireless monitoring instrument supply power for the sensing device, the second processing circuit, the second wireless signal transceiver, and other energy consuming devices, and the instrument battery is a rechargeable battery, such as a zinc-manganese battery, a cadmium-nickel battery, a hydrogen-nickel battery, a lithium battery, and the like. Because the capacity of the instrument battery and the spare battery is small, even if a plurality of spare batteries are redundantly configured for each target wireless monitoring instrument, the cost increase and the instrument volume increase are not obvious, and therefore the battery redundancy and the reliability of the wireless monitoring instrument can be improved at a low cost.

It should be noted that, compared with a target wireless monitoring instrument of a nuclear island plant of a nuclear power plant which only depends on a battery of the target wireless monitoring instrument, the target wireless monitoring instrument of the nuclear island plant of the nuclear power plant can obtain electric energy through wireless charging, so that a large-capacity instrument battery which can supply power for the instrument in one or even several refueling periods is not required to be configured for the target wireless monitoring instrument, a battery with a smaller capacity can be used, the requirements on the capacity of the instrument battery and the energy consumption of the instrument are remarkably reduced, and the cost of the target wireless monitoring instrument is also reduced.

In a specific implementation, the target wireless monitoring instrument has a wireless charging capability, so that a small-capacity and low-cost instrument battery can be used, each target wireless monitoring instrument can be redundantly configured with multiple groups of standby instrument batteries without increasing excessive cost and volume, the target wireless monitoring instrument is powered by one of the batteries, and when the chargeable electric quantity of the used instrument battery is attenuated to a preset threshold value or other faults occur, the target wireless monitoring instrument is switched to use the standby battery through a battery pipeline circuit, so that the reliability of the target wireless monitoring instrument is improved.

Since the relative position of the target wireless monitoring meter and the wireless charging station is fixed, existing beam forming techniques can be readily used to directionally transmit the radio beam to the wireless charging receiver of the target wireless monitoring meter. The radio wave beam frequency for transmitting energy to the target wireless monitoring instrument is high enough; for example, millimeter waves or terahertz waves are employed to ensure the directivity of the beam, thereby improving the energy transmission efficiency.

As an example, the wireless charging station further comprises a first power converter for converting the electric energy of the power source into the current required by the wireless charging transmitter

As an example, the wireless charging station includes a first wireless signal receiver electrically connected to the wireless charging transmitter and the power supply, respectively, the first wireless signal receiver receiving the control signal transmitted from the control device, turning on or off the power supply, and directionally transmitting the radio beam of the wireless charging transmitter to the wireless charging receiver of the target wireless monitoring instrument.

As an example, the amount of electricity of the storage battery is larger than the sum of the required electricity consumption of the target wireless monitoring instrument covered in the charging range in a preset period.

As an example, when the battery is used for power supply, the first power converter is a DC-DC conversion circuit (Direct current-Alternating current), and may be implemented by a switching circuit with a semiconductor switch.

In a specific implementation, if the wireless charging stations are powered by a battery, each wireless charging station needs to be equipped with a large capacity battery and a first power converter. A wireless charging transmitter of the wireless charging station is connected to the battery through a first power converter and is configured to draw power from the battery. The total charge of the battery of the wireless charging station should be much higher than the total charge of the meter batteries of the surrounding target wireless monitoring meter or meters, and the total charge of the battery of the wireless charging station is sufficient to power the target wireless monitoring meter or meters surrounding the wireless charging station during at least one refueling cycle of the nuclear power plant complex, where losses in wireless power transmission are taken into account substantially.

The technical scheme of using the storage battery has the advantages that when a loss of service accident similar to the first nuclear power station accident in the Fudao occurs, the wireless charging station can still supply power to the target wireless monitoring instrument in the wireless charging range of the wireless charging station, and therefore the usability of the nuclear power station monitoring system is improved.
