Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a communication base station with nuclear protection function and its power regulation method. Background Art

[0002] Multiple sets of communication equipment are required in nuclear energy facilities. Through the communication equipment, communication connections between components such as sensors and valves and the control terminal are constructed. In the prior art, the corresponding wireless communication connection can be constructed by deploying communication base stations. However, due to the strong nuclear radiation in the nuclear facility, the communication base stations applied in non-nuclear environments have poor protection capabilities. When directly applied to nuclear facilities, the communication components will be interfered with or unable to work properly. For example, the single-event effect in a strong radiation environment causes the signal data bits in the storage unit to flip, and the strong radiation causes signal distortion or an increase in the bit error rate of the transceiver chip, resulting in packet errors or communication link interruptions. In the prior art, a protective cover is set to protect the internal communication components. However, the protective cover is not conducive to the heat dissipation of the communication base station. Because the heat generated inside the base station exceeds its designed heat dissipation capacity, it is easy to cause heat accumulation inside the base station and burn out the components, affecting the safety and stability of the operation of the communication base station. Therefore, the communication base station with a protection function in the prior art method has the problem that the internal heat generation exceeds the heat dissipation capacity. Summary of the Invention

[0034] Please refer to Figure 1 andFigure 2 , as shown in the figure, an embodiment of the present invention provides a power regulation method, which is applied to the controller 10 of a communication base station with nuclear protection function. The controller 10 is communicatively connected to the contact temperature sensor 20 and the power supply circuit 30 in the communication base station to realize the transmission of data information. The controller 10 is also communicatively connected to the external temperature sensor 40 arranged outside the communication base station through a connection line to realize the transmission of data information. The controller 10 can be a control chip (such as an MCU control chip) configured in the communication base station for information reception and data processing. The controller 10 can issue control instructions to control each component. The contact temperature sensor 20 is used to detect the temperature of the central area of the bottom plate 41. There are multiple high-power devices, such as optical modules, signal transceivers and other components, arranged in the central area of the bottom plate 41. The external temperature sensor 40 is used to detect the ambient temperature outside the communication base station. The power supply circuit 30 is used to receive control instructions from the controller 10 and adjust the power output to components such as optical modules and signal transceivers (realize power regulation by adjusting the current and voltage output to the corresponding components). As Figure 1 shown, the method includes steps S110 to S150.

[0035] S110. If a received startup instruction is received, obtain the internal temperature collected by the contact temperature sensor and determine whether it meets the preset regulation conditions.

[0036] If a received startup instruction is received, obtain the internal temperature collected by the contact temperature sensor and determine whether it meets the preset regulation conditions. If a received base station startup instruction is received, the controller can obtain the internal temperature collected by the contact temperature sensor, and the controller further determines whether the internal temperature meets the preset regulation conditions.

[0037] In a specific embodiment, step S110 includes sub-steps: determine whether the internal temperature is greater than the temperature threshold set in the regulation conditions; if the internal temperature is not greater than the temperature threshold, it is determined that the regulation conditions are not met; if the internal temperature is greater than the temperature threshold, it is determined that the regulation conditions are met.

[0038] Specifically, it can be determined whether the internal temperature is greater than the temperature threshold set in the regulation conditions. If it is greater, it indicates that the internal temperature is relatively high and power regulation is required, so it is determined that the regulation conditions are met; if the internal temperature is not greater than the temperature threshold, it indicates that the internal temperature does not exceed the heat dissipation capacity and power regulation is not required, and it is determined that the regulation conditions are not met. For example, the temperature threshold can be set to 95 °C.

[0039] In a specific embodiment, before determining that the regulation condition is not satisfied, it further includes: obtaining the heating rate corresponding to the internal temperature; determining whether the heating rate is greater than the rate threshold set in the regulation condition; if the heating rate is not greater than the rate threshold, determining that the regulation condition is not satisfied; if the heating rate is greater than the rate threshold, determining that the regulation condition is satisfied.

[0040] Further, if it is determined that the internal temperature is not greater than the temperature threshold, the heating rate corresponding to the internal temperature can be further obtained, and two historical internal temperatures obtained before the internal temperature can be obtained; calculate the first rate between the two historical internal temperatures obtained before: (T i-1 -T i-2 ) / Δt, calculate the second rate between the internal temperature obtained this time and the previous historical internal temperature obtained: (T i -T i-1 ) / Δt, where i is the serial number of the internal temperature and Δt is the time difference between two acquisitions of the internal temperature. Perform a weighted average calculation on the first rate and the second rate to obtain the corresponding heating rate. For example, set the weighting coefficient of the first rate to 0.25 and the weighting coefficient of the second rate to 0.75; the obtained heating rate is a signed value. If the sign is positive, it indicates that the inside of the communication base station is heating up, and if the sign is negative, it indicates that the inside of the communication base station is cooling down.

[0041] Determine whether the obtained heating rate is greater than the rate threshold set in the regulation condition. If the heating rate is greater than the rate threshold, determine that the regulation condition is satisfied. If the heating rate is not greater than the rate threshold, determine that the regulation condition is not satisfied.

[0042] S120. If the internal temperature satisfies the regulation condition, obtain the external temperature collected by the external temperature sensor.

[0043] If the internal temperature satisfies the regulation condition, obtain the external temperature collected by the external temperature sensor. If the internal temperature satisfies the regulation condition, the external temperature can be obtained through the external temperature sensor; the higher the external temperature, the more difficult it is for the heat dissipation chassis to dissipate heat externally, and the lower the external temperature, the more conducive it is for the heat dissipation chassis to dissipate heat externally. If the internal temperature does not satisfy the regulation condition, after an interval of Δt time, collect the internal temperature obtained by the contact temperature sensor again and repeat the above steps.

[0044] S130. Obtain the regulation coefficient corresponding to the internal temperature and the external temperature according to the preset power regulation strategy.

[0045] Obtain the regulation coefficient corresponding to the internal temperature and the external temperature according to the preset power regulation strategy. The internal temperature and the external temperature can be analyzed through the power regulation strategy to obtain the corresponding regulation coefficient, and the current power can be adjusted through the regulation coefficient.

[0046] In a specific embodiment, step S130 includes sub-steps: calculating the temperature difference value between the internal temperature and the external temperature; obtaining the temperature difference coefficient matching the temperature difference value according to the temperature difference coefficient configuration table in the power regulation strategy; inputting the temperature difference coefficient and the internal temperature into the regulation coefficient calculation formula in the power regulation strategy to calculate the corresponding regulation coefficient.

[0047] Specifically, the temperature difference value between the internal temperature and the external temperature can be calculated. The temperature difference coefficient configuration table contains multiple temperature ranges. The calculated temperature difference value can be matched with the temperature ranges to obtain a temperature range matching the temperature difference value. Each temperature range corresponds to a coefficient value, so the coefficient value corresponding to a temperature range matching the temperature difference value can be obtained as the temperature difference coefficient. For example, the information in the temperature difference coefficient configuration table is shown in Table 1:

[0048] Table 1

[0049] Group Temperature range Coefficient value 1 0 ≤ and < 15 °C 11.32 2 15 ≤ and < 30 °C 11.01 3 30 ≤ and < 50 °C 10.74 4 50 ≤ and < 70 °C 10.38 5 70≤ 9.93

[0050] Furthermore, input the temperature difference coefficient and the internal temperature into the regulation coefficient calculation formula to calculate the corresponding regulation coefficient. The regulation coefficient calculation formula is shown in formula (1):

[0051]

[0052] Among them, s is the calculated regulation coefficient, r is the obtained corresponding temperature difference coefficient, ln is the logarithm operation symbol, and T i is the currently obtained internal temperature.

[0053] S140. Generate a corresponding power regulation instruction according to the regulation coefficient and the preset rated power.

[0054] Generate a corresponding power regulation instruction according to the regulation coefficient and the preset rated power. Further generate a corresponding power regulation instruction according to the regulation coefficient and the rated power of the device to be regulated. The rated powers set for different devices are different. According to the obtained regulation coefficient and the rated power of the device to be regulated, a corresponding power regulation instruction can be generated.

[0055] In a specific embodiment, step S140 includes sub-steps: multiplying the regulation coefficient by the rated power to obtain a corresponding regulated power value; generating a corresponding power regulation instruction according to the regulated power value.

[0056] Specifically, the regulation coefficient can be multiplied by the rated power to obtain the regulation power value of a specific device. According to the obtained regulation power value, a corresponding power regulation instruction can be generated. The power regulation instruction includes the regulation time and the corresponding regulation power value. Then, a power regulation instruction can be generated for each device that needs to be regulated.

[0057] S150: Send the power regulation instruction to the power supply circuit to adjust the working power of the device through the power supply circuit.

[0058] Send the power regulation instruction to the power supply circuit to adjust the working power of the device through the power supply circuit. Send the power regulation instruction to the power supply circuit, so as to adjust the working power of the corresponding device through the power supply circuit. Specifically, the voltage value of the electrical signal output by the controller and the corresponding pin of the device can be adjusted according to the regulation power value in the power regulation instruction. For a specific device, if the corresponding regulation power value increases, the voltage value of the electrical signal output by the corresponding pin is increased; if the corresponding regulation power value decreases, the voltage value of the electrical signal output by the corresponding pin is decreased. The power supply circuit obtains the electrical signal from the pin of the controller and correspondingly adjusts the power supply power output to the specific device according to the voltage value of the electrical signal to achieve the adjustment of the working power of the device.

[0059] In the power regulation method provided by the embodiment of the present invention, if a received start instruction is received, the internal temperature collected by the contact temperature sensor is obtained and it is determined whether it meets the preset regulation condition; if the internal temperature meets the regulation condition, the external temperature collected by the external temperature sensor is obtained; according to the preset power regulation strategy, the regulation coefficient corresponding to the internal temperature and the external temperature is obtained; according to the regulation coefficient and the preset rated power, a corresponding power regulation instruction is generated; the power regulation instruction is sent to the power supply circuit to adjust the working power of the device through the power supply circuit. The communication base station with nuclear protection function applies the above power regulation. By monitoring the internal temperature and the external temperature in real time and dynamically adjusting the working power of the device, it is possible to avoid the internal components from overheating due to the heat generation exceeding the heat dissipation capacity, effectively ensuring the safety and reliability of the communication base station with nuclear protection function.

[0060] In this embodiment, as Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a communication base station with nuclear protection function. The communication base station includes a housing 1, a protective cover 2, a heat dissipation housing 3, a circuit board 4 and an interface adapter board 5. The housing 1 includes an upper housing 11 and a lower housing 12. One end of the lower housing 12 facing the upper housing 11 is provided with a housing cavity 121 that is recessed inward. The upper housing 11 covers the upper part of the lower housing 12 to enclose the housing cavity 121. The heat dissipation housing 3 is covered and arranged on the bottom surface of the housing cavity 121. The interface adapter board 5 is arranged between the bottom surface of the housing cavity 121 and the heat dissipation housing 3. One side of the heat dissipation housing 3 facing the interface adapter board 5 is provided with a receiving cavity 31 for receiving the interface adapter board 5. The protective cover 2 covers the heat dissipation housing 3, and the circuit board 4 is clamped between the protective cover 2 and the heat dissipation housing 3.

[0061] In a more specific embodiment, as Figure 6 and Figure 7 shown, the circuit board 4 includes a bottom board 41 and a combining board 42. The bottom board 41 is arranged closely against the heat dissipation housing 3. The combining board 42 is arranged closely against the protective cover 2. The bottom board 41 and the combining board 42 are electrically connected. A plurality of wiring ports 421 are provided on the combining board 42. Specifically, a shielding cover 43 is arranged between the bottom board 41 and the combining board 42, and the size of the shielding cover 43 is the same as that of the bottom board 41. Among them, the wiring ports 421 are all arranged near the edge of the combining board 42. As Figure 8 shown, a plurality of grooves are provided on the side of the shielding cover 43 facing the bottom board 41, and the grooves can be used to accommodate the electrical components arranged on the bottom board 41.

[0062] Specifically, as Figure 4 shown, the circuit board 4 includes a bottom board 41 and a combining board 42. The bottom board 41 is used to arrange circuit devices such as radio frequency and power amplifier. Then the circuit devices arranged on the bottom board 41 are used for signal transceiver, information processing, etc. Wiring ports 421, microstrip lines, etc. are arranged on the combining board 42. Then the combining board 42 is used for signal forwarding and transmission. The circuit devices arranged on the bottom board 41 need more protection. For this reason, a shielding cover 43 can be arranged between the bottom board 41 and the combining board 42. On the one hand, the shielding cover 43 can increase the radiation protection ability of the circuit devices on the bottom board 41. On the other hand, it has an EMC (electromagnetic compatibility) shielding function, which improves the electromagnetic isolation degree between the bottom board 41 and the combining board 42. Specifically, the size of the shielding cover 43 can be set to be the same as that of the bottom board 41, so as to realize the full coverage of the shielding cover 43 on the bottom board 41.

[0063] Further, since most of the circuit devices provided on the bottom plate 41 are concentrated in the central region, the heat generated by the circuit devices is also mostly concentrated in the middle region of the circuit board 4. To prevent the high temperature generated by the circuit devices from affecting the operation of the wiring ports 421, the wiring ports 421 can be arranged at the edges of the multiplexing board 42. Specifically, the interfaces of the wiring ports 421 can be arranged radially along the multiplexing board 42, and the interfaces of the wiring ports 421 all face outward. The interfaces of the wiring ports 421 are used to connect with connecting wires.

[0064] The controller 10, the contact temperature sensor 20 and the power supply circuit 30 are all arranged on the bottom plate. The external temperature sensor 40 is electrically connected to the wiring port 421 through a connecting wire led out from the wiring port 421. The specific communication connection relationship is as Figure 2 shown. The controller 10 communicates with the contact temperature sensor 20 and the power supply circuit 30 to realize the transmission of data information. The controller 10 also communicates with the external temperature sensor 40 arranged outside the communication base station through a connecting wire to realize the transmission of data information.

[0065] A 5G communication device can be arranged in the above communication base station, so that it can be configured to be used as a 5G communication base station with nuclear protection function.

[0066] Since the heat dissipation housing 3 dissipates heat by passive heat dissipation, its heat dissipation power is limited. To prevent the heat generation power of the components inside the communication base station from being too high and causing the heat generation power to exceed the heat dissipation capacity of the heat dissipation housing 3, when the internal temperature is relatively high, it is necessary to limit the operating power of the components inside the communication base station.

[0067] Specifically, as Figure 4 shown, after the upper housing 11 and the lower housing 12 are combined, a housing cavity 121 is formed inside. Then, the protective cover 2, the heat dissipation housing 3, the circuit board 4 and the interface adapter board 5 are all arranged in the housing cavity 121. In a specific embodiment, as Figure 6 shown, the housing 1 can be set to be rectangular, and a plurality of L-shaped fittings 13 are fixedly arranged on the side of the housing 1. Pass the bolt 131 through the fixing holes on the L-shaped fittings 13, and the housing 1 can be fixed to the wall; then the side of the lower housing 12 facing away from the upper housing 11 can be fixed to the wall. A plurality of connector 15 through holes are provided on one side of the lower housing 12, and a connector 15 is assembled in each connector 15 through hole. The connector 15 is used to connect with the connecting wire led out from the wiring port 421 and realize communication with other external devices.

[0068] The wall thickness of the housing 1 is 1.2 mm, and the material is 304 stainless steel. The edges of the upper housing 11 and the lower housing 12 are both bent to form bent sides to improve the strength of the housing 1. As Figure 3As shown, a handle 14 is provided on one side of the housing 1 opposite to the through hole of the connector 15, which facilitates lifting and gripping.

[0069] During the operation of the electrical components provided on the circuit board 4, heat is generated. The heat dissipation housing 3 is arranged closely against the circuit board 4, so that the electrical components provided on the circuit board 4 can be dissipated by the heat dissipation housing 3. Further, a thermal conductive gel can be coated on the side of the heat dissipation housing 3 facing the circuit board 4, so as to increase the heat conduction area between the heat dissipation housing 3 and the circuit board 4 and improve the heat conduction efficiency. The heat generated by the devices on the circuit board 4 diffuses outwards through the thermal conductive gel, the heat dissipation housing 3, and the lower housing 12. As Figure 10 shown, a receiving cavity 31 is provided on one side of the heat dissipation housing 3 facing the interface adapter board 5, and the receiving cavity 31 is used to receive the interface adapter board 5.

[0070] Specifically, to achieve the nuclear protection performance to meet actual use, the material of the protective cover 2 is copper, and the thickness is 14-18 mm, and preferably 15-16 mm in the preferred embodiment; or, the material of the protective cover 2 is 304 stainless steel, and the thickness is 16-20 mm, and preferably 17-18 mm in the preferred embodiment.

[0071] In a more specific embodiment, as Figure 6 shown, an inner concave cavity 32 is provided on the side of the heat dissipation housing 3 facing the protective cover 2, and the edge of the inner cavity 32 protrudes towards the protective cover 2 to form an annular wall 321; the protective cover 2 is provided with a concave cavity adapted to the annular wall 321; when the protective cover 2 is covered on the heat dissipation housing 3, the annular wall 321 is embedded in the concave cavity to form a sealed cavity; the circuit board 4 is arranged in the sealed cavity. Specifically, the heat dissipation housing 3 further includes heat dissipation fins 33 arranged around the annular wall 321. Among them, as Figure 9 and Figure 10 shown, the heat dissipation fins 33 are arranged perpendicular to and staggered with each other, and a homogeneous substrate 34 fixedly connected to the heat dissipation fins 33 is provided on the bottom surface of the heat dissipation housing 3 facing the lower housing 12, and the outer dimension of the homogeneous substrate 34 is adapted to the inner wall dimension of the housing cavity 121.

[0072] Further, to improve the protection performance of the protective cover 2, an inner cavity 32 can be provided on the side of the heat dissipation housing 3, and the periphery of the inner cavity 32 protrudes outwards to form an annular arm, and the protective cover 2 is provided with a concave cavity. When the protective cover 2 is covered on the heat dissipation housing 3, the annular arm is embedded in the concave cavity to form a sealed cavity corresponding to the inner cavity 32, and the circuit board 4 is arranged in the sealed cavity. Specifically, as Figure 5 and 6As shown, the inner cavity 32 and the concave cavity can be set to be circular. Similarly, the protective cover 2 can be set to be circular. A plurality of side screw holes are provided on the outer edge of the protective cover 2, and a plurality of outwardly protruding screw holes are correspondingly provided on the heat dissipation housing 3. The bolts 131 pass through the side screw holes in sequence and are screwed into the outwardly protruding screw holes, thereby firmly fixing the protective cover 2 on the heat dissipation housing 3.

[0073] To further improve the heat conduction efficiency, as Figure 9 shown, heat dissipation fins 33 can be provided around the annular surrounding arm. Then, the heat dissipation fins 33 can efficiently conduct the heat in the annular surrounding arm area to the lower housing 12, thereby improving the heat dissipation efficiency. Further, the heat dissipation fins 33 can be set to be perpendicular and staggered with each other to form a grid-shaped heat dissipation assembly; one side surface of each heat dissipation fin 33 is fixedly arranged on a homogeneous substrate 34, and each heat dissipation fin 33 is perpendicular to the plane where the homogeneous substrate 34 is located. The bottom surface of the homogeneous substrate 34 is closely attached to the bottom surface of the lower housing 12, and the outer dimension of the homogeneous substrate is adapted to the inner wall dimension of the housing cavity 121; thereby further expanding the contact area between the heat dissipation housing 3 and the lower housing 12 and improving the heat dissipation performance.

[0074] In a specific embodiment, the homogeneous substrate 34 can be set to be rectangular. Similarly, the inner wall of the housing cavity 121 encloses a rectangular area; the outer dimension of the homogeneous substrate is set to be slightly smaller than the dimension of the above rectangular area.

[0075] In a more specific embodiment, as Figure 5 shown, the protective cover 2 includes a first cover body 21 and a second cover body 22; an L-shaped concave platform 221 is provided at one side edge of the second cover body 22 facing the first cover body 21, and the first cover body 21 is recessed inward to form a first cover body concave cavity; when the first cover body 21 covers the second cover body 22, the edge of the first cover body concave cavity is embedded in the L-shaped concave platform 221. Specifically, a heat-conducting and insulating substrate 6 is provided on the bottom surface of the housing cavity 121, and the interface adapter board 5 is arranged by being attached to the heat-conducting and insulating substrate 6. Among them, the interface adapter board 5 is fixedly clamped to the heat-conducting and insulating substrate 6 through a snap cover 51.

[0076] Specifically, the protective cover 2 can be set to be composed of a first cover body 21 and a second cover body 22.
