Description

Technical Field

[0001] The present application relates to the field of communication technologies, and particularly to a power supply device for a repeater. Background Art

[0002] With the rapid development of mobile communication technologies, users have higher and higher requirements for network coverage, and the requirements for in-building deep coverage are increasing day by day. After the construction of the "breadth" of the wireless network, it gradually focuses on the construction of the "depth". At present, the wireless network coverage in most "breadth" areas has been achieved, but there are still some indoor scenarios (such as elevators, basements, etc.) with blind spots and weak coverage problems.

[0003] Micro-power repeater coverage devices can be used to solve the network coverage problems in indoor scenarios such as elevators and underground parking lots. For example, a repeater includes a main control unit and an antenna, etc. The repeater can receive the base station signal through the antenna and retransmit it to the indoor scenario by the main control unit, so as to achieve the wireless network coverage in the indoor scenario. Since the repeater needs to be installed on a physical building, a power supply solution for a repeater is to re-layout or transform the power supply lines on the physical building, which requires high costs and a complex implementation process. Another power supply solution for a repeater is to use a traditional photovoltaic power supply device, but the traditional photovoltaic power supply device has a relatively large floor area and weight, resulting in high installation and maintenance costs and limited operation.

[0043] To make the technical problems, technical solutions and advantages to be solved by the present application clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0044] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure or characteristic related to the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in any suitable manner in one or more embodiments.

[0045] The digital micro-power repeater can select one or more assigned carriers to work within all or part of the frequency bands of each system, and it is a single-system or multi-system micro repeater that can convert radio frequency signals into digital signals for digital processing.

[0046] Taking the elevator-type micro-power repeater as an example, it mainly consists of two parts: the main control unit 1 and the car remote unit 2. The main control unit 1 needs to be connected to the retransmission antenna 3 downward, and the car remote unit 2 needs to be connected to the car receiving antenna upward and the car coverage antenna downward respectively to achieve the coverage of the elevator shaft. Its working principle is shown as Figure 1 shown.

[0047] The main purpose of the elevator-type micro-power repeater is to solve the communication coverage problem inside the elevator. Especially when the elevator is in a moving state, the signal is usually severely interfered with or lost. By using this device, the signal coverage blind area inside the elevator can be effectively eliminated, interference can be suppressed, and a stable and reliable signal can be provided for the users inside the elevator. The repeater antenna is generally deployed on the roof. The repeater can receive the signal sent by the macro station 5 through the receiving antenna 4. After being amplified by the amplification unit, the signal sent by the macro station 5 is sent into the elevator shaft through the retransmission antenna 3, so that the terminal users in the elevator car can communicate normally.

[0048] As Figure 2 shown, an embodiment of the present application provides a power supply device for a repeater, including:

[0049] A flexible photovoltaic module 10, which supports switching between an unfolded state and a retracted state; the flexible photovoltaic module 10 generates electricity in the unfolded state and stops generating electricity in the retracted state;

[0050] A control module 20, which is connected to the control end of the flexible photovoltaic module 10; the control module 20 is used to control the flexible photovoltaic module 10 to be in the unfolded state under a first condition and to control the flexible photovoltaic module 10 to be in the retracted state under a second condition;

[0051] A power storage module 30, the input end of the power storage module 30 is connected to the output end of the flexible photovoltaic module 10, and the output end of the power storage module 30 is respectively connected to the control module 20 and the repeater 40; the power storage module 30 is used to store the electric energy output by the flexible photovoltaic module 10 and supply power to the control module 20 and the repeater 40;

[0052] Wherein, the first condition and the second condition are related to at least one of the following: the time of the environment where the power supply device of the repeater is located, the humidity of the environment where the power supply device of the repeater is located.

[0053] Optionally, the flexible photovoltaic module 10 has a flexible structure and can be bent or folded. Under the control of the control module 20, the flexible photovoltaic module 10 can support switching between the unfolded state and the retracted state. For example, when the flexible photovoltaic module 10 is in the unfolded state, it can perform photoelectric conversion and generate electricity if exposed to light; for another example, when the flexible photovoltaic module 10 is in the retracted state, it can avoid being exposed to light and stop generating electricity. In this way, since the flexible photovoltaic module 10 supports switching between the unfolded state and the retracted state, the flexible photovoltaic module 10 can be controlled to switch between the unfolded state and the retracted state according to the illumination time and / or climate change. For example, the flexible photovoltaic module 10 can be unfolded for power generation under good environmental conditions (such as having light, sufficient light, low humidity, no rain, etc.), and retracted to stop power generation under harsh environmental conditions (such as no light, scarce light, high humidity, rain, etc.), that is, while ensuring that the flexible photovoltaic module 10 can provide electrical energy, it can also avoid its loss or even damage in harsh environments, so as to extend the service life of the flexible photovoltaic module 10.

[0054] Optionally, the control module 20 can output a first electrical signal to the flexible photovoltaic module 10 under a first condition, and then the flexible photovoltaic module 10 switches to the unfolded state under the action of the first electrical signal, that is, the control module 20 controls the flexible photovoltaic module 10 to be in the unfolded state under the first condition; the control module 20 can also output a second electrical signal to the flexible photovoltaic module 10 under a second condition, and then the flexible photovoltaic module 10 switches to the retracted state under the action of the second electrical signal, that is, the control module 20 controls the flexible photovoltaic module 10 to be in the retracted state under the second condition.

[0055] Optionally, the first condition is related to at least one of the time in the environment where the repeater power supply device is located and the humidity in the environment where the repeater power supply device is located, and the second condition is related to at least one of the time in the environment where the repeater power supply device is located and the humidity in the environment where the repeater power supply device is located. For example, if the first condition is related to the time in the environment where the repeater power supply device is located and the second condition is related to the time in the environment where the repeater power supply device is located, the times corresponding to the first condition and the second condition are different (such as the time ranges do not overlap). For another example, if the first condition is related to the humidity in the environment where the repeater power supply device is located and the second condition is related to the humidity in the environment where the repeater power supply device is located, the humidities corresponding to the first condition and the second condition are different (such as the humidity ranges do not overlap), etc. The embodiments of the present application are not limited thereto.

[0056] Optionally, the flexible photovoltaic module 10 generates electricity in the deployed state, and the generated electric energy can be output to the energy storage module 30 for storage. On the one hand, the energy storage module 30 can output electric energy to the repeater 40 to supply power to the repeater 40, and on the other hand, it can also output electric energy to the control module 20 to supply power to the control module 20. In this way, the repeater 40 is powered by the electric energy generated by the flexible photovoltaic module 10, solving the problems of large occupied space, complex power supply line layout, and high cost of the current power supply device for the repeater 40. Moreover, the control module 20 is powered by the electric energy generated by the flexible photovoltaic module 10, solving the power supply problem of the power supply device for the repeater 40 itself.

[0057] In the embodiment of the present application, the flexible photovoltaic module 10 is used to generate electricity in the power supply device for the repeater 40. Since the flexible photovoltaic module 10 has the characteristics of light weight and small volume, the problem of large occupied space of the current power supply device for the repeater 40 can be solved. And by the control module 20 controlling the flexible photovoltaic module 10 to be in the deployed state for power generation under the first condition and controlling the flexible photovoltaic module 10 to be in the retracted state to stop power generation under the second condition, it can be ensured that the flexible photovoltaic module 10 can provide electric energy while avoiding its loss or even damage in harsh environments, so as to extend the service life of the flexible photovoltaic module 10; the electric energy generated by the flexible photovoltaic module 10 is output to the energy storage module 30 for storage and supplies power to the control module 20 and the repeater 40, which can solve the problems of complex power supply line layout and high cost of the current power supply device for the repeater 40, and also solve the power supply problem of the power supply device for the repeater 40 itself.

[0058] Optionally, the first condition includes at least one of the following:

[0059] The time in the environment where the repeater power supply device is located is in the first time period;

[0060] The humidity in the environment where the repeater power supply device is located is less than or equal to the first threshold;

[0061] And / or, the second condition includes at least one of the following:

[0062] The time in the environment where the repeater power supply device is located is in the second time period;

[0063] The humidity in the environment where the repeater power supply device is located is greater than or equal to the second threshold;

[0064] Wherein, the first time period is different from the second time period, or there is no overlap between the first time period and the second time period.

[0065] For example, the first time period and the second time period can be preset according to the lighting time of the geographical area where the repeater power supply device is deployed (specifically, it can be achieved by setting the signal sending time of the control module 20. For example, the control module 20 sends a first electrical signal in the first time period and a second electrical signal in the second time period, etc.), or can also be dynamically set according to the time when the lighting signal is collected (specifically described in the following embodiments), etc. The embodiments of the present application are not limited thereto.

[0066] For example: the first time period can be the time period when the power supply device can receive light in the environment where the power supply device is located (or the geographical area where it is deployed), or the time period when the received light amount is greater than or equal to a preset threshold; the second time period can be the time period when the power supply device cannot receive light in the environment where the power supply device is located (or the geographical area where it is deployed), or the time period when the received light amount is less than the preset threshold, etc. For example, the first time period can be daytime, or from 9:00 to 16:00 in world time; the second time period can be nighttime, or after 16:00 in world time to 9:00 the next day. The embodiments of the present application are not limited thereto.

[0067] Among them, the first threshold is less than or equal to the second threshold.

[0068] For example, the first threshold T1 and the second threshold T2 can be equal (i.e., T1 = T2), that is, the first condition includes that the humidity of the environment where the repeater power supply device is located ≤ T1 = T2, and the second condition includes that the humidity of the environment where the repeater power supply device is located > T1 = T2; or, the first condition includes that the humidity of the environment where the repeater power supply device is located < T1 = T2, and the second condition includes that the humidity of the environment where the repeater power supply device is located ≥ T1 = T2.

[0069] For another example, the first threshold may be less than the second threshold (i.e., T1 < T2), that is, the first condition includes that the humidity of the environment where the repeater power supply device is located ≤ T1 < T2, and the second condition includes that the humidity of the environment where the repeater power supply device is located ≥ T2 > T1. Optionally, when the humidity of the environment where the repeater power supply device is located is between T1 and T2 (i.e., T1 < the humidity of the environment where the repeater power supply device is located < T2), the control module 20 may control the flexible photovoltaic module 10 to maintain its current state. For example: when the humidity ≤ T1, the control module 20 controls the flexible photovoltaic module 10 to be in the unfolded state; if the humidity exceeds T1 (e.g., T1 < humidity < T2), the flexible photovoltaic module 10 may temporarily remain in the unfolded state, and when the humidity reaches T2 (e.g., humidity ≥ T2), the control module 20 controls the flexible photovoltaic module 10 to switch to the retracted state; if the humidity further decreases to T2 (e.g., T1 < humidity < T2), the flexible photovoltaic module 10 may temporarily remain in the retracted state, and when the humidity decreases to T1 (e.g., humidity < T1), the control module 20 controls the flexible photovoltaic module 10 to switch to the unfolded state. This can prevent the flexible photovoltaic module 10 from frequently switching between the unfolded state and the retracted state when the humidity of the environment where the repeater power supply device is located is close to T1 or T2, and can extend the service life of the flexible photovoltaic module 10.

[0070] Optionally, the control module 20 may include:

[0071] a light detection unit, which may be disposed on the flexible photovoltaic module 10 or near the flexible photovoltaic module 10;

[0072] a drive control unit, which is electrically connected between the light detection unit and the flexible photovoltaic module 10 respectively.

[0073] Wherein, the light detection unit is used to detect the amount of light irradiated on the flexible photovoltaic module 10. For example, the light detection unit may convert the optical signal into an electrical signal, and quantify the amount of light irradiated on the flexible photovoltaic module 10 based on the voltage value or current value or other electrical parameter values of the electrical signal, so as to realize the detection of the amount of light irradiated on the flexible photovoltaic module 10, such as a light detector, etc. The embodiments of the present application are not limited thereto.

[0074] The light detection unit can output an electrical signal corresponding to the amount of light to the drive control unit. The drive control unit controls the flexible photovoltaic module to switch between the unfolded state and the retracted state according to the electrical signal corresponding to the amount of light. For example, the drive control unit may include a comparator for comparing the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the amount of light with a threshold value. For example, when the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the amount of light is greater than or equal to the threshold value, it indicates that the amount of light is greater than or equal to the preset threshold, and then a first electrical signal can be output to the flexible photovoltaic module 10 to control the flexible photovoltaic module 10 to be in the unfolded state; if the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the amount of light is less than the threshold value, it indicates that the amount of light is less than the preset threshold, and then a second electrical signal can be output to the flexible photovoltaic module 10 to control the flexible photovoltaic module 10 to be in the retracted state. Of course, the embodiments of the present application are not limited thereto.

[0075] It should be noted that the spatial range where the light detection unit is disposed close to the flexible photovoltaic module 10 can be set based on the actual application scenario. For example, it is necessary to ensure that the light detection unit can detect the amount of light irradiated on the flexible photovoltaic module 10, etc. The embodiments of the present application are not limited thereto.

[0076] Optionally, as Figure 3 shown, the control module 20 includes:

[0077] a humidity detection unit 201, which is disposed on the flexible photovoltaic module 10 or close to the flexible photovoltaic module 10;

[0078] a drive control unit 202, which is electrically connected between the humidity detection unit 201 and the flexible photovoltaic module 10 respectively.

[0079] Among them, the humidity detection unit 201 is used to detect the humidity of the environment where the repeater power supply device is located. For example, the humidity detection unit 201 can convert the humidity into an electrical signal, and quantify the humidity of the environment where the repeater power supply device is located based on the voltage value, current value, or other electrical parameter values of the electrical signal, so as to detect the humidity value of the environment where the repeater power supply device is located, such as a humidity detector, etc. The embodiments of the present application are not limited thereto.

[0080] The humidity detection unit 201 outputs an electrical signal corresponding to the humidity to the drive control unit 202; the drive control unit 202 controls the flexible photovoltaic module 10 to switch between the unfolded state and the retracted state according to the electrical signal corresponding to the humidity. For example, the drive control unit 202 may include a comparator for comparing the magnitude of the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the humidity with a threshold value. For example, when the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the humidity is less than or equal to a first threshold value, it indicates that the humidity is less than or equal to the first threshold, and a first electrical signal may be output to the flexible photovoltaic module 10 to control the flexible photovoltaic module 10 to be in the unfolded state; if the voltage value, current value, or other electrical parameter value of the electrical signal corresponding to the humidity is greater than or equal to a second threshold value, it indicates that the humidity is greater than or equal to the second threshold, and a second electrical signal may be output to the flexible photovoltaic module 10 to control the flexible photovoltaic module 10 to be in the retracted state. Of course, the embodiments of the present application are not limited thereto.

[0081] It should be noted that the spatial range where the humidity detection unit 201 is disposed close to the flexible photovoltaic module 10 may be set based on the actual application scenario. For example, it is necessary to ensure that the humidity detection unit can detect the humidity of the environment where the flexible photovoltaic module 10 is located, etc. The embodiments of the present application are not limited thereto.

[0082] Optionally, continue to refer to Figure 3 , the flexible photovoltaic module 10 includes:

[0083] A flexible photovoltaic film 101 that generates electricity in the unfolded state and stops generating electricity in the retracted state;

[0084] A stretching mechanism 102 that is mechanically connected to the flexible photovoltaic film 101 and electrically connected to the control module 20;

[0085] Wherein, the control module 20 outputs a first electrical signal to the stretching mechanism 102 under a first condition, and the stretching mechanism 102 stretches the flexible photovoltaic film 101 to the unfolded state under the action of the first electrical signal; the control module 20 outputs a second electrical signal to the stretching mechanism 102 under a second condition, and the stretching mechanism 102 retracts the flexible photovoltaic film 101 to the retracted state under the action of the second electrical signal.

[0086] In this embodiment, the flexible photovoltaic film 101 has a flexible structure and can be bent or folded. The flexible photovoltaic film 101 can be supported to switch between the unfolded state and the retracted state under the control of the control module 20.

[0087] For example, the winding and stretching mechanism 102 can adopt a folding method to control the flexible photovoltaic film 101 to switch between the unfolded state and the wound state (for example, in a folding method similar to a folding fan or a folding umbrella, the flexible photovoltaic film 101 is folded and wound or unfolded). Alternatively, the winding and stretching mechanism 102 can also adopt a reel method to control the flexible photovoltaic film 101 to switch between the unfolded state and the wound state (for example, the flexible photovoltaic film 101 is wound or unfolded through a reel), etc. The embodiments of the present application are not limited thereto.

[0088] Optionally, the thickness level of the flexible photovoltaic film 101 is in millimeters. By using the flexible photovoltaic film 101 with a thickness level in millimeters, the repeater power supply device can have the advantages of light weight and small volume. And it enables the flexible photovoltaic film 101 to exhibit the characteristics of being easily bent or folded, ensuring that the flexible photovoltaic film 101 can switch between the wound state and the unfolded state.

[0089] Optionally, as Figure 4 shown, the flexible photovoltaic film 101 includes: a flexible photovoltaic functional layer 1011 for generating electricity, and a flexible encapsulation layer 1012 covering the flexible photovoltaic functional layer;

[0090] Among them, the thickness level of the flexible photovoltaic functional layer 1011 is in nanometers, and the thickness level of the flexible encapsulation layer 1012 is in micrometers.

[0091] For example, the flexible encapsulation layer 1012 can include an encapsulation layer and a base layer; the flexible photovoltaic functional layer 1011 can include, but is not limited to: indium tin oxide (ITO), a hole transport layer, a perovskite photovoltaic layer, an electron transport layer, and an electrode. The flexible photovoltaic functional layer 1011 can be prepared by one or more solution process technologies such as spraying, doctor blading, and spin coating. The embodiments of the present application are not limited thereto.

[0092] In this embodiment, by using the flexible photovoltaic functional layer 1011 with a thickness level in nanometers (such as 800 nanometers) and the flexible encapsulation layer 1012 with a thickness level in micrometers, the thickness level of the flexible photovoltaic film 101 can be in millimeters, so that the flexible photovoltaic film 101 can exhibit the characteristics of being easily bent or folded, and ensure that the repeater power supply device has the advantages of light weight and small volume.

[0093] Optionally, the flexible photovoltaic film 101 is a perovskite flexible photovoltaic film.

[0094] For example, the perovskite flexible photovoltaic film can adopt a reverse structure. Compared with traditional photovoltaic devices using relatively heavy traditional silicon-based photovoltaic panels, the embodiments of the present application use the perovskite flexible photovoltaic film to provide electric energy, which has the advantages of simple manufacturing process and assembly process, low cost, light weight, and convenient installation. AsFigure 5 As shown, traditional silicon-based photovoltaic panels usually have a designed specification of 1650mm×992mm, a weight of about 20kg, and an average of 1.83g / cm2. While the perovskite flexible photovoltaic film in the embodiment of the present application can be designed with an area of 15mm×15mm, a weight of 0.0365g, and an average of 0.016g / cm2. That is, compared with the traditional silicon-based photovoltaic panel, the weight per unit area of the flexible photovoltaic film 101 in the embodiment of the present application can be reduced by at least two orders of magnitude, thereby reducing the space occupied by the repeater power supply device.

[0095] Optionally, as Figure 6 shown, the repeater power supply device further includes: a power conversion module 50.

[0096] The output end of the flexible photovoltaic module 10 is connected to the input end of the energy storage module 30 through the power conversion module 50; the power conversion module 50 is used to perform power conversion on the voltage and / or current output by the flexible photovoltaic module 10, and output a voltage within a predetermined range and / or a current within a predetermined range to the energy storage module 30.

[0097] In this embodiment, considering that the voltage and / or current output by the flexible photovoltaic module 10 may change due to changes in the amount of light (or light intensity), by setting the power conversion module 50 to perform power conversion on the voltage and / or current output by the flexible photovoltaic module 10, it is ensured that a stable voltage and / or current can be output to the energy storage module 30 (that is, output a voltage within a predetermined range and / or a current within a predetermined range to the energy storage module 30, such as a voltage and / or current that meets the charging conditions of the energy storage module 30, etc.). In this way, by setting the power conversion module 50, it is ensured that the flexible photovoltaic module 10 can output a stable voltage and / or current to the energy storage module 30, so as to avoid damage to the energy storage module 30 and thus extend the service life of the energy storage module 30.

[0098] Optionally, continue to refer to Figure 6 , the repeater power supply device further includes: a battery management module 60.

[0099] The output end of the energy storage module 30 is respectively connected to the control module 20 and the repeater 40 through the battery management module 60; the battery management module 60 is used to distribute the electric energy of the energy storage module 30 and output it to the control module 20 and the repeater 40 respectively.

[0100] For example, the battery management module 60 can record and distribute the electrical energy of the energy storage module 30, such as recording the number of charge and discharge cycles, the charge amount, the discharge amount, the remaining power, etc. For example, the battery management module 60 can perform power distribution based on the remaining power to ensure that the energy storage module 30 supplies power to the control module 20 and the repeater 40 in a reasonable and balanced manner.

[0101] Optionally, the energy storage module 30 includes: blade batteries.

[0102] In this embodiment, blade batteries are used as the energy storage module 30 to store the clean energy generated by the flexible photovoltaic module 10 and provide stable power for the control module 20 and the repeater 40. Moreover, the blade batteries have the advantages of small volume and light weight, which can reduce the space occupied by the power supply device of the repeater.

[0103] The working process of the power supply device of the repeater according to the present application will be described below in conjunction with specific examples:

[0104] In the sunshine mode (or called the working mode, that is, the flexible photovoltaic film is in the unfolded state), the control module determines whether to control the flexible photovoltaic film to be in the unfolded state according to the set first condition. Among them, the first condition may include at least one of the following:

[0105] Condition 1: Local sunshine time is from 9:00 to 16:00;

[0106] Condition 2: The detector in the control module does not detect rain in the environment (or detects that the environmental humidity is less than or equal to the first threshold);

[0107] Optionally, when any one of the above Condition 1 and Condition 2 is satisfied, or when both the above Condition 1 and Condition 2 are satisfied, it is determined that it is necessary to control the flexible photovoltaic film to be in the unfolded state for power generation.

[0108] The calculation formula for the photoelectric conversion efficiency of the flexible photovoltaic film is as follows:

[0109] PCE = V × I × FF

[0110] Among them, PCE is the photoelectric conversion efficiency, V is the open-circuit voltage, I is the short-circuit voltage, and FF is the fill factor. Based on laboratory tests, the photoelectric conversion efficiency of the flexible photovoltaic film is 17.17%, as Figure 7 shown.

[0111] Taking the fifth type of area with poor sunshine as an example, the average annual solar radiation is about 1000 KWh / m 2 , the sunshine time is short. Considering factors such as occlusion and device aging, through the formula: 1000 KWh / m 2 × 1 m 2× 17.17% × 90% ÷ 365 days = 423 Wh, and it is calculated that per 1 m 2 The flexible photovoltaic film generates about 423 Wh of electricity per day on average. In this way, taking the power consumption of an elevator-type low-power repeater as about 20 W as an example, even in areas with poor sunlight, using a 2 m 2 flexible photovoltaic film can enable the elevator-type low-power repeater to operate effectively for more than 40 hours.

[0112] In this mode, the clean energy generated by the flexible photovoltaic film is stored in the blade battery after passing through the power conversion module. At the same time, the battery management module monitors and records the energy storage situation of the blade battery in real time to distribute power to the repeater and the control module.

[0113] In the night or rainy day mode (or standby mode, that is, the flexible photovoltaic film is in the retracted state), the control module determines whether to control the flexible photovoltaic film to be in the retracted state according to the set second condition. Among them, the second condition may include at least one of the following:

[0114] Condition 1: Local time from 16:00 to 9:00 am of the next day;

[0115] Condition 2: The detector in the control module detects rain in the surrounding environment (or detects that the environmental humidity is greater than or equal to the second threshold);

[0116] Optionally, when any one of the above Condition 1 and Condition 2 is satisfied, or when both of the above Condition 1 and Condition 2 are satisfied, it is determined that it is necessary to control the flexible photovoltaic film to be in the retracted state to stop generating electricity.

[0117] In this mode, the battery management module can control the blade battery to supply power to the repeater and the control module.

[0118] In the embodiments of the present application, the device uses a flexible photovoltaic film to generate electric energy, which can solve the high-cost problem caused by the use of wire-pulling power supply for the repeater, and can reduce the electricity cost expenditure, reduce carbon emissions, reduce the impact on the environment, and reduce the energy cost by providing clean energy through the flexible photovoltaic film; the device can also control the extension or contraction of the flexible photovoltaic film according to the light time and humidity detection, etc., rationally utilize the flexible photovoltaic film to generate electricity, and greatly extend the service life of the flexible photovoltaic film; and the lightweight feature of the flexible photovoltaic film can ensure installation and later maintenance, and improve the structural stability of the equipment and the physical building.
