[0002] At present, providing high-quality video resources for sharing is one of the means to achieve balanced education. As a terminal device for recording video resources, recording and broadcasting equipment plays a core role in the processing, acquisition, transmission and recording of audio and video information. In addition to normal teaching scenarios, the demand for recording and broadcasting in outdoor, training, conference and teaching and research scenarios is also increasing. In order to make recording and broadcasting equipment suitable for a variety of application scenarios, portable mobile recording and broadcasting application solutions have emerged.

[0003] In the portable mobile recording and broadcasting application scenario, the recording and broadcasting equipment is no longer installed and fixed on the desktop or wall. Instead, according to the change of application scenarios, the recording and broadcasting equipment can be moved to the physical environment of the current application scenario (such as a conference room, training room or outdoor environment). When moving the recording and broadcasting equipment, the recording and broadcasting equipment is no longer charged through the AC power interface on the desktop or wall, that is, there is no guarantee that the recording and broadcasting equipment will be charged in time.

[0062] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0063] The recording and broadcasting equipment can also be understood as the various devices included in the recording and broadcasting system, which can integrate and synchronously record the video, audio and image signals of electronic equipment recorded on site to generate standardized streaming media files for external live broadcast, storage, post-editing and on-demand broadcasting, etc.

[0066] The audio capture device can be an independent microphone or a microphone installed on a smart device, such as a microphone installed on a smartphone, a microphone installed on a smart speaker, or a microphone installed on a laptop computer.

[0067] In some cases, the video acquisition device and the audio acquisition device may also be integrated together, for example, the camera on a laptop computer serves as a video acquisition device, and the microphone on the laptop computer serves as an audio acquisition device.

[0068] Currently, the description is made by taking the video acquisition device as an independent camera and the audio acquisition device as an independent microphone as an example.

[0069] The recording and broadcasting host can obtain video data collected by at least one video acquisition device and audio data collected by at least one audio acquisition device, and then can integrate and record the video data and audio data to obtain audio and video files. In addition, the recording and broadcasting host can also play the currently recorded video data and / or audio data and other content, upload the recorded audio and video files to the cloud, broadcast the acquired video data and / or audio data live, and provide other interactions for users. The device type, structure and specific functions of the recording and broadcasting host are not currently limited, and only need to meet the relevant functions of recording and broadcasting.

[0070] The camera, microphone and recording and broadcasting host are all devices with built-in batteries, and the batteries are rechargeable batteries. In this way, when the batteries of the camera, microphone and recording and broadcasting host are all charged, the camera, microphone and recording and broadcasting host can be set up and used in a relatively free environment.

[0071] Based on the aforementioned recording and broadcasting equipment, the embodiment of the present application provides a recording and broadcasting equipment storage box, which can store the aforementioned recording and broadcasting equipment, so as to realize convenient movement of the recording and broadcasting equipment when the recording and broadcasting equipment storage box is moved. In addition, the recording and broadcasting equipment storage box can also charge the recording and broadcasting equipment stored inside when connected to a power source, so that the recording and broadcasting equipment can be charged when stored in the storage box, ensuring the convenience of charging the recording and broadcasting equipment.

[0072] refer to Figure 1-2 The recording and broadcasting equipment storage box 10 includes: a box body 11 and a box cover 12 hinged to the box body 11, the outer surface of the box body 11 is provided with a power inlet 21, the inner surface of the box body 11 is provided with a plurality of storage bins 22, each storage bin 22 is provided with a power outlet 23, and the box body 11 is also provided with a transfer bin module 24, which is respectively connected to the power inlet 21 and the power outlet 23.

[0073] The storage compartment 22 is used to store the corresponding recording and broadcasting equipment. The power access port 21 is used to receive an external power signal. The transfer compartment module 24 is used to convert the external power signal into a target power signal suitable for the recording and broadcasting equipment when the corresponding recording and broadcasting equipment is stored in the storage compartment 22 and the power access port 21 receives an external power signal, and send the target power signal to the corresponding power output port 23. The power output port 23 is used to provide the target power signal to the recording and broadcasting equipment stored in the storage compartment 22 so that the recording and broadcasting equipment can be charged.

[0074] The top of the box body 11 of the recording and broadcasting equipment storage box 10 is hinged with a box cover 12. After the box cover 12 rotates relative to the box body 11, the recording and broadcasting equipment storage box 10 can be closed and opened. Among them, the implementation method of the hinge and the fixing method of the box body 11 and the box cover 12 when the recording and broadcasting equipment storage box 10 is closed are not limited at present. It can be understood that the outer surface material and the internal material of the box body 11 are not limited at present.

[0075] The inner surface of the box 11 is provided with a plurality of storage bins 22, each of which can store a recording and broadcasting device. The storage bin 22 can be understood as a groove in the box 11, and the recording and broadcasting device is placed in the groove, so that the recording and broadcasting device can be stored in the storage bin 22. The shape of the groove can be determined according to the shape of the recording and broadcasting device stored therein, which is not limited in the embodiment, and only needs to satisfy that the groove can fix the recording and broadcasting device placed therein.

[0076] The number of storage bins 22 can also be set according to actual conditions. In the embodiment, the example of at least two storage bins 22 is used for description. In this case, at least two storage bins 22 can store one type of recording and broadcasting equipment and at least two types of recording and broadcasting equipment. For example, the number of storage bins 22 is 2, and they are all used to store audio acquisition equipment. For another example, the number of storage bins 22 is 3, and they are respectively used to store a recording and broadcasting host, a video acquisition device, and an audio acquisition device. For another example, the number of storage bins 22 is 4, and they are respectively used to store a recording and broadcasting host, a video acquisition device, and two audio acquisition devices.

[0077] In the embodiment, the storage bin 22 is used as an example to describe that it can store at least two types of recording and broadcasting equipment. For example, Figure 1 and Figure 2 Three storage bins 22 are shown as an example, and the three storage bins 22 are used to store the recording and broadcasting host, the video acquisition device and the audio acquisition device respectively.

[0078] Need to explain, Figure 1 The different sizes of the storage bins 22 corresponding to the three types of recording and broadcasting equipment are only illustrated by way of example, without any specific limitation on the shape of the storage bins 22 .

[0079] When the recording and broadcasting device comes with a rechargeable battery, the surface of the recording and broadcasting device is generally provided with a charging interface for connecting to a power source. The type of charging interface is not currently limited. The types of charging interfaces commonly used by recording and broadcasting devices on the market are all applicable to the charging interfaces mentioned in this application. When charging the recording and broadcasting device, it is necessary to first insert a suitable charging cable into the charging interface, and the other end of the charging cable is connected to a power source or connected to a power source through a charger head to charge the battery through the power source.

[0080] In the embodiment, in order to realize charging of the recording and broadcasting device in the recording and broadcasting device storage box 10, a power outlet 23 is provided in each storage compartment 22. The power outlet 23 is compatible with the charging interface used by the recording and broadcasting device stored in the storage compartment 22. For example, if the charging interface is a USB Type-C type, then the power outlet 23 in the storage compartment 22 is a USB Type-C plug that can be inserted into the USB Type-C charging interface.

[0081] Optionally, when the storage bin 22 is provided with a power outlet 23, the power outlet 23 can be directly fixed on the surface of the groove where the storage bin 22 is located. In this case, the position of the power outlet 23 in the storage bin 22 can be determined according to the position of the charging interface of the recording and broadcasting device when the recording and broadcasting device is stored, so as to ensure that the power outlet 23 can be inserted into the charging interface when the recording and broadcasting device is stored in the storage bin 22. In this case, the surface of the groove of the storage bin 22 can be provided with a through hole, and the power outlet 23 can be fixed in the through hole, or the power outlet 23 and the storage bin 22 are integrally formed.

[0082] Optionally, when the storage bin 22 is provided with a power outlet 23, the power outlet 23 can also be fixed in the storage bin 22 by a charging cable. In this case, the power outlet 23 can also be moved, and the range of movement can be determined according to the length of the charging cable and the fixed position. When the recording and broadcasting device is stored in the storage bin 22, the power outlet 23 is inserted into the charging interface of the recording and broadcasting device. In this case, the surface of the groove of the storage bin 22 can be provided with a through hole, and the charging cable can be fixed in the through hole.

[0083] Regardless of whether the power outlet 23 is directly fixed in the storage bin 22 or indirectly fixed in the storage bin 22 through a charging cable, it can be considered that the side of the power outlet 23 that can be used by the recording and broadcasting device is located in the storage bin 22. The other side of the power outlet 23 is also connected to a charging cable, which is located inside the box 11 and connected to the transfer bin module 24 disposed inside the box 11. At this time, it can also be considered that the transfer bin module 24 is connected to the power outlet 23 disposed in each storage bin 22.

[0084] It should be noted that there may be two states when the recording and broadcasting device is stored in the storage bin 22, one is that the charging interface of the recording and broadcasting device is connected to the power output port 23, and the other is that the charging interface of the recording and broadcasting device is not connected to the power output port 23. In the embodiment, it is assumed that when the recording and broadcasting device is stored in the storage bin 22, the charging interface of the recording and broadcasting device is connected to the power output port 23, so as to facilitate the description of the charging process of the recording and broadcasting device.

[0085] A power input port 21 is provided on the outer surface of the box body 11. The power input port 21 can be directly connected to an external power source, or can be connected to an external power source through a charging cable. The type of the power input port 21 is not currently limited. For example, the power input port is a three-phase AC power input port, and the three-phase AC power is an electric power system composed of three AC circuits with the same frequency, equal potential amplitude, and a phase difference of 120°. The ground wire in the three-phase AC power input port is connected to the metal material of the box body 11 to avoid electric shock when the user touches the recording and broadcasting equipment storage box 10, thereby realizing electric shock protection. The specific position, structure or shape of the metal material in the box body 11 is not currently limited.

[0086] The power input port 21 can be directly fixed on the outer surface of the box body 11, or can be fixed on the outer surface of the box body 11 through a charging cable. The specific setting method can refer to the setting method when the power output port 23 is set in the storage bin 22.

[0087] The position of the power input port 21 on the outer surface of the box 11 is not limited at present. At present, it can be considered that the side of the power input port 21 that can be connected to the external power source is located on the outer surface of the box 11. The other side of the power input port 21 is also connected to a charging cable, which is located inside the box 11 and connected to the transfer compartment module 24 set inside the box 11. At this time, it can also be considered that the transfer compartment module 24 is connected to the power input port 21 set on the outer surface of the box 11.

[0088] It should be noted that the outer surface of the box 11 can be understood as the external surface, that is, when the recording and broadcasting equipment storage box 10 is closed, the user can still touch the outer surface of the box 11. The inner surface of the box 11 can be understood as the surface that the user can touch only when the recording and broadcasting equipment storage box 10 is opened. The material of the outer surface of the box 11, the material of the inner surface, and the material of the box cover 12 are not currently limited. In some cases, the power input port 12 can also be set on the inner surface of the box 11.

[0089] Based on the aforementioned connection relationship, the external power connected to the power input port 21 can be processed by the adapter module 24 and then charged by the recording and broadcasting device through the power output port 23 .

[0090] Specifically, after the power input port 21 is connected to an external power source, the voltage and current provided by the power source can flow into the transfer compartment module 24. In the embodiment, the voltage and current provided by the external power source are recorded as external power signals. The type of the external power source is not currently limited. In order to facilitate understanding of the technical solution, in the embodiment, an example is given in which an external power source provides alternating current (such as city electricity).

[0091] The transfer compartment module 24 has a power supply change function. For example, when the external power supply is AC power, the transfer compartment module 24 needs to convert the AC input into a DC output. In an embodiment, after receiving the external power signal, the transfer compartment module 24 can convert it into a power supply suitable for charging the recording and broadcasting device. After that, the applicable voltage and current are provided to the recording and broadcasting device through the power output port 23 so that the recording and broadcasting device can be charged. At present, the voltage and current that can be directly charged by the recording and broadcasting device are recorded as the target power signal. The transfer compartment module 24 obtains the target power signal after processing the external power signal.

[0092] Among them, the process of the transfer chamber module 24 processing the external power signal is not currently limited. For example, the transfer chamber module 24 can perform surge suppression, rectification, filtering, power management, etc. on the external power signal. Among them, the surge is an instantaneous overvoltage that exceeds the normal voltage, that is, the transfer chamber module 24 can suppress the surge after receiving the external power signal. In terms of power electronics, rectification refers to converting AC power into DC power, that is, the transfer chamber module 24 converts the surge-suppressed AC power into DC power through rectification. Filtering is often used to filter out ripples in the rectifier output, that is, to filter out ripples in DC power. At this time, the transfer chamber module 24 can obtain usable DC power. After that, the transfer chamber module 24 can process the DC power according to the charging voltage and charging current required by each recording and broadcasting device to obtain a target power signal suitable for each recording and broadcasting device.

[0093] The transfer chamber module 24 may be composed of one or more circuit boards, on which circuits are mounted to realize the functions of the transfer chamber module 24, for example, surge suppression circuits, rectification circuits, filtering circuits, power management chips, and power supplies are mounted on the circuit board to realize the functions of the transfer chamber module 24. The specific structure of the circuit mounted on the circuit board is not currently limited.

[0094] In one embodiment, the transfer compartment module 24 is located inside the box 11, and the user cannot see the transfer compartment module 24 inside the box 11 during use. At this time, the fixing method of the transfer compartment module 24 inside the box 11 is not currently limited.

[0095] In one embodiment, the transfer compartment module 24 outputs multiple target power signals, and each target power signal flows into the charging interface of the recording and broadcasting device through a power output port 23 to charge the recording and broadcasting device. Optionally, when the type of recording and broadcasting device is different, the voltage and / or current of the required target power signal may be different. At this time, the voltage and / or current of the multiple target power signals output by the transfer compartment module 24 are different, that is, the transfer compartment module 24 can obtain multiple target power signals with different voltages and / or currents based on external power signal processing to meet the charging requirements of different recording and broadcasting devices. Optionally, when a certain recording and broadcasting device is fully charged, the transfer compartment module 24 may no longer send the target power signal to the power output port 23 corresponding to the recording and broadcasting device to achieve energy saving.

[0096] In one embodiment, only when the power inlet 21 is connected to an external power signal and the recording and broadcasting device is stored in the storage compartment 22 , the transfer compartment module 24 will send a target power signal to the power outlet 23 provided in the storage compartment 22 .

[0097] It should be noted that when the transfer compartment module 24 is in operation or other modules inside the box 11 require power supply, the external power signal received by the transfer compartment module 24 can also power the transfer compartment module 24 and other modules. It can be understood that the amount of power required by the transfer compartment module 24 and other modules is much less than the amount of power required by each recording and broadcasting device.

[0098] In practical applications, the power inlet 21 can also be included in the transfer compartment module 24 .

[0099] As described above, a plurality of storage compartments for storing recording and broadcasting equipment are arranged in the box of the recording and broadcasting equipment storage box, and a power outlet is arranged in each storage compartment, and the power outlet is connected to the power access port on the surface of the box through the adapter compartment module in the box. When the power access port is connected to an external power signal, for the recording and broadcasting equipment stored in the storage compartment, the adapter compartment module can convert the external power signal into a target power signal suitable for charging the recording and broadcasting equipment, and flow the target power signal into the recording and broadcasting equipment through the power outlet, so as to charge the recording and broadcasting equipment. Through the aforementioned recording and broadcasting equipment storage box, the technical problem that the charging convenience of the recording and broadcasting equipment cannot be guaranteed in the portable mobile recording and broadcasting application scheme in the related technology can be solved. Through the power outlet, the power access port and the adapter compartment module, the recording and broadcasting equipment stored in the storage compartment can be charged. At this time, during the movement of the recording and broadcasting equipment, if there is an external power source that can be connected, then the recording and broadcasting equipment can be charged during the movement. In addition, multiple storage compartments are provided to store multiple recording and broadcasting devices, so that the internal space of the recording and broadcasting device storage box can be reasonably utilized, that is, multiple recording and broadcasting devices can be stored and moved at the same time, and multiple recording and broadcasting devices can be charged at the same time, thereby improving the charging efficiency of multiple recording and broadcasting devices.

[0100] In one embodiment of the present application, reference Figure 3 , which is in Figure 2 On the basis of the above, a monitoring module 25 is added. At this time, a monitoring module 25 is also provided in the box body 11 of the recording and broadcasting device storage box 10. The monitoring module 25 is connected to the transfer compartment module 24. The monitoring module 25 is used to monitor the current value of each target power signal output by the transfer compartment module 24 and / or the temperature value inside the monitoring box body 11 during the charging process of the recording and broadcasting device, and when the current value and / or the temperature value meet the charging stop condition, instruct the transfer compartment module 24 to stop providing the target power signal to the recording and broadcasting device. The transfer compartment module 24 is also used to stop providing the target power signal according to the instruction of the monitoring module 25.

[0101] Exemplarily, the monitoring module 25 can also monitor the charging process of the recording and broadcasting device, so as to instruct the transfer compartment module 24 to stop providing the target power signal to the recording and broadcasting device when the device is fully charged or abnormally charged. The setting position of the monitoring module 25 in the box 11 is not currently limited. Optionally, the monitoring module 25 is set inside the box 11, and the user cannot see the monitoring module 25.

[0102] In one embodiment, during the operation of the monitoring module 25 , the current value of the target power signal and / or the temperature value inside the box can be monitored.

[0103] The current value of the target power signal can also be understood as the specific value of the charging current. When the transfer compartment module 24 sends the corresponding target power signal to each power output port 23, the monitoring module 25 can monitor the real-time current value of each target power signal. Generally speaking, during the charging process of the recording and broadcasting device, as the amount of electricity in the battery increases, the required charging current will decrease. When the real-time current value of the target power signal decreases and is less than the preset current value, it indicates that the recording and broadcasting device is fully charged, wherein the preset current value is the current value provided by the power supply when the recording and broadcasting device is in trickle charging, that is, the current value of the target power signal under trickle charging. The preset current value can be set in combination with the actual parameters of the recording and broadcasting device, and the preset current values ​​corresponding to different recording and broadcasting devices may be different. When the monitoring module 25 detects that the current current value of a certain target power signal is less than the corresponding preset current value, it can be considered that the corresponding recording and broadcasting device is fully charged, that is, it is considered that the current current value meets the condition for stopping charging. The condition for stopping charging refers to the condition for stopping power supply to the recording and broadcasting device. At this time, the monitoring module 25 can instruct the transfer compartment module 24 to stop supplying power to the corresponding recording and broadcasting device, that is, the transfer compartment module 24 stops providing the target power signal of the channel. It is understandable that if the current value of the target power signal of other paths is not less than the corresponding preset current value, the adapter module 24 will continue to provide the target power signal of other paths so that other recording and broadcasting devices can continue to charge.

[0104] The temperature value in the box can reflect the ambient temperature when the recording and broadcasting device is charging. At present, the monitoring module 25 can collect temperature values ​​at one or more positions in the box. Moreover, the more positions collected, the more accurately the monitoring module 25 grasps the ambient temperature when the recording and broadcasting device is charging. In one embodiment, the monitoring module 25 needs to monitor the temperature of each storage bin 21 at least to obtain the temperature value of each storage bin 21. The temperature value of the storage bin 21 can reflect the heat consumption of the recording and broadcasting device stored therein when charging to a certain extent. The higher the temperature value of the storage bin 21, the higher the heat consumption of the recording and broadcasting device, and the more heat the recording and broadcasting device generates. If the heat consumption of the recording and broadcasting device is too high when charging, it may cause damage to the recording and broadcasting device. Therefore, when the monitoring module 25 determines that the temperature value of the current storage bin 21 is too high, it can be determined that the heat consumption of the recording and broadcasting device is too high. If the charging continues, it may cause damage to the recording and broadcasting device. At this time, it can be considered that the current temperature value of the storage bin 21 meets the condition for stopping charging. In one embodiment, a temperature threshold can be set in advance, and the temperature thresholds corresponding to different recording and broadcasting devices can be the same or different. During the charging process of the recording and broadcasting device, the monitoring module 25 can continuously or at a certain time interval collect the temperature value of each storage bin 21. Afterwards, when the monitoring module 25 determines that a certain temperature value currently collected reaches the temperature threshold, it means that the temperature of the corresponding storage bin 21 is too high, and then determines that the heat consumption of the recording and broadcasting device during charging is too high, which may cause loss to the recording and broadcasting device. At this time, the monitoring module 25 can instruct the transfer bin module 24 to stop supplying power to the corresponding recording and broadcasting device, that is, the transfer bin module 24 stops providing the target power signal. Optionally, when the monitoring module 25 instructs the transfer bin module 24 to stop supplying power to the recording and broadcasting device, it can be to instruct the transfer bin module 24 to stop providing the target power signal to the recording and broadcasting device in the storage bin 21 whose current temperature value exceeds the temperature threshold, or it can be to instruct the transfer bin module 24 to stop providing the target power signal to all recording and broadcasting devices. In one embodiment, since the area of ​​the cabinet 11 is limited, if the temperature value at a certain location exceeds the temperature threshold, the temperature values ​​at other locations will also be high. In order to ensure the safety of the cabinet 11 and the recording and broadcasting equipment, the monitoring module 25 instructs the transfer compartment module 24 to stop providing the target power signal to all the recording and broadcasting equipment.

[0105] Optionally, in addition to collecting the temperature value of each storage bin 21, the monitoring module 25 can also collect the temperature value of other locations in the box body 11. For example, the temperature value of the transfer bin module 24 is collected to prevent the temperature from being too high when the transfer bin module 24 provides the target power signal. Currently, the transfer bin module 24 can also have a corresponding temperature threshold. When the monitoring module 25 determines that the temperature value of the transfer bin module 24 reaches the temperature threshold, it is determined that the temperature value reaches the condition for stopping charging. At this time, the monitoring module 25 instructs the transfer bin module 24 to stop providing the target power signal to all recording and broadcasting devices.

[0106] Exemplarily, the implementation method of the transfer compartment module 24 stopping providing the target power signal to the recording and broadcasting device according to the instruction of the monitoring module 25 is not limited at present. For example, the transfer compartment module 24 stops sending the target power signal to the power output port, and for another example, the transfer compartment module 24 disconnects the connection with the external power signal.

[0107] For example, when the monitoring module 25 determines that any temperature value satisfies the condition for stopping charging, it instructs the transfer compartment module 24 to disconnect from the power access port 22, that is, to disconnect from the external power signal. At this time, a circuit breaker may also be provided in the transfer compartment module 24, and the connection with the power access port 21 may be disconnected through the circuit breaker, that is, the monitoring module 25 may start the circuit breaker to disconnect the transfer compartment module 24 from the external power signal. When the monitoring module 25 determines that a certain current value satisfies the condition for stopping charging, it instructs the transfer compartment module 24 to stop outputting the target power signal of the corresponding path, so that the recording and broadcasting equipment in the corresponding storage compartment 22 no longer receives the target power signal. At this time, the transfer compartment module 24 continues to receive the external power signal and continues to provide the target power signal to other recording and broadcasting equipment.

[0108] It can be understood that when the monitoring module 25 monitors the current value and the temperature value at the same time, it determines in real time whether the current value meets the condition for stopping charging and whether the temperature value meets the condition for stopping charging. If the current value meets the condition for stopping charging, a corresponding response is made to stop providing the target power signal. If the temperature value meets the condition for stopping charging, a corresponding response is made to stop providing the target power signal.

[0109] As described above, by setting a monitoring module in the box, monitoring the current value of the target power signal and / or the temperature value inside the box through the monitoring module, and instructing the transfer compartment module to stop providing the target power signal when the current value and / or the temperature value meet the charging stop condition, the recording and broadcasting equipment storage box has an intelligent and safe charging service, which automatically stops providing the target power signal when the battery is fully charged or charging is abnormal, thereby saving power energy and ensuring the charging safety of the recording and broadcasting equipment storage box and the recording and broadcasting equipment.

[0110] In one embodiment of the present application, the external power signal is an alternating current signal. Figure 4When the external power signal is an AC signal, the adapter module 24 includes: a surge protection unit 241, a rectifier and filter unit 242, a power management unit 243 and multiple power units 244. Each power unit 244 corresponds to a power output port 23. The surge protection unit 241 is used to receive the AC signal connected to the power access port 21 and suppress the surge voltage in the AC signal. The rectifier and filter unit 242 is used to convert the AC signal output by the surge protection unit 241 into a DC signal. The power management unit 243 is used to adjust the DC signal into a DC signal that can be used by each power unit. The power unit 244 is used to obtain a target power signal suitable for the corresponding recording and broadcasting equipment based on the adjusted DC signal, and provide the target power signal to the corresponding power output port 23.

[0111] Exemplarily, the AC power signal is three-phase AC power.

[0112] The power inlet 21 is connected to the surge protection unit 241 in the transfer compartment module 24. When the AC signal flows from the power inlet 21 into the transfer compartment module 24, it first passes through the surge protection unit 241. At this time, the input end of the surge protection unit 241 has three interfaces to receive three-phase AC power through three interfaces. The surge protection unit 241 is used to suppress surges in AC signals, that is, to absorb surges or peak voltages in AC signals to avoid damage to other devices, modules or units on the charging line caused by surges, and to achieve overcurrent protection. The surge protection unit 241 can be implemented by a surge protection circuit (also referred to as a surge protector), which is installed on the circuit board of the transfer compartment module 24. When the AC signal passes through the surge protection circuit, if a surge voltage occurs in the AC signal, the surge protection circuit will embed the surge voltage and absorb the surge energy to suppress the surge. The circuit structure and parameters of the surge protection circuit are not limited in the embodiment, and the currently existing surge protection circuit can be used as long as the aforementioned functions are met.

[0113] The surge protection unit 241 is also connected to the rectifier and filter unit 242 in the transfer bin module 24. The rectifier and filter unit 242 is used to realize rectification and filtering. After the AC signal output by the surge protection unit 241 flows into the rectifier and filter unit 242, the rectifier and filter unit 242 can rectify and filter the AC signal (i.e., AC power) into a suitable DC voltage. At present, the DC voltage output by the rectifier and filter unit 242 is recorded as a DC signal, that is, the rectifier and filter unit 242 outputs DC power. The DC power can be used as electric energy to provide to the subsequent power management unit 243. The rectifier and filter unit 242 can be implemented by a rectifier and filter circuit, and the rectifier and filter circuit is installed on the circuit board of the transfer bin module 24. Optionally, the surge protection unit 241 and the rectifier and filter unit 242 can be installed on the same circuit board.

[0114] The rectifier filter circuit consists of two parts: a rectifier circuit and a filter circuit. Among them, the rectifier circuit is a circuit that converts AC power into DC power. The circuit structure and parameters of the rectifier circuit are not currently limited. The existing rectifier circuit can be used as long as the above functions are met. The filter circuit often follows the rectifier circuit. The DC power output by the rectifier circuit may contain a large amount of AC components. The filter circuit can filter out the AC components in the DC pulse voltage in the DC power (i.e., the ripple in the voltage) to obtain a smooth DC voltage (i.e., a DC signal). The circuit structure and parameters of the filter circuit are not currently limited. The existing filter circuit can be used as long as the above functions are met.

[0115] In an optional manner, a filter circuit for preventing the external power signal from causing power fluctuation (ie, interference) to other circuits or components inside the housing 11 may be provided between the surge protection unit 241 and the rectifying and filtering unit 242. The filter circuit may use an existing filter circuit.

[0116] The rectifier and filter unit 242 is also connected to the power management unit 243 in the transfer bin module 24. In one embodiment, the power management unit 243 includes a power factor correction (PFC) circuit, a resonance (LLC) circuit, and an output rectifier and filter circuit. Optionally, the PFC circuit is a common circuit. At present, the PFC circuit can be composed of a PFC main control chip (i.e., a main control IC) and a peripheral circuit. The model of the PFC main control IC is not currently limited. The PFC circuit can further boost the DC voltage (i.e., a DC signal) after rectification and filtering and perform power factor correction. The DC voltage after power factor correction has higher active power. The DC voltage corrected by the PFC circuit is used as the input of the LLC circuit. Among them, in addition to the necessary inductors and capacitors, the LLC circuit also includes an LLC main control IC and peripheral circuits. Among them, the model of LLC master control IC is not limited at present, for example, a chip with model FA6A31N-C6-L3 is used as LLC master control IC, based on the control of LLC master control IC, the LLC circuit can provide the voltage value required by each power supply unit 224, and the voltage value is a DC voltage value. At present, the voltage value required by each power supply unit 224 is recorded as a DC signal for use by each power supply unit 224. The voltage value provided by the LLC circuit can be filtered by the output rectifier filter circuit before being used by each power supply unit 224, wherein the output rectifier filter circuit can adopt the currently existing filter circuit, and the output rectifier filter circuit can reduce the ripple voltage in the DC voltage, thereby reducing the ripple voltage in the target power signal output to each power output port 23.

[0117] The power management unit 243 is also connected to each power supply unit 244. That is, the output rectifier filter circuit in the power management unit 243 is connected to each power supply unit 224 to provide the required DC voltage to each power supply unit 244. At present, the DC signal output by the power management unit 243 can be divided into multiple paths, and the number of paths is consistent with the number of power supply units 244 to ensure that each power supply unit 244 can receive the DC voltage output by the power management unit 243. An optional method is to provide applicable DC power (i.e., target power signal) for different recording and broadcasting equipment through a transformer, and the DC voltage output by the LLC circuit can be provided for transformer transformation after passing through the output rectifier filter circuit. At this time, one side of the transformer (including one winding) can be connected to the output rectifier filter circuit, and multiple windings are set on the other side of the transformer, and each power output port has a corresponding winding, and the number of turns of the winding can be determined according to the charging voltage applicable to the corresponding recording and broadcasting equipment. At this time, the winding corresponding to the power output port and the peripheral circuit corresponding to the winding can be considered as a power supply unit 244. The side of the transformer connected to the output rectifier filter circuit can be considered as the input port of each power supply unit 244. In this case, each power supply unit 244 shares one input port. Alternatively, the side of the transformer connected to the output rectifier filter circuit can be considered as the output port of the power management unit 243, and the winding of the transformer included in each power supply unit 244 can be considered as the input port of the power supply unit 244. It should be noted that Figure 4 The power management unit 243 is connected to each power supply unit 244 through three paths, which is only used to illustrate that the power management unit 243 can provide a DC voltage for use by each power supply unit 244.

[0118] Currently, the power management unit 243 , the surge protection unit 241 , and the rectification and filtering unit 242 may be installed on the same circuit board, or on different circuit boards, which is not limited in the embodiment.

[0119] Each storage bin 22 has a corresponding power supply unit 244, which can be understood as a power supply for the recording and broadcasting equipment in the storage bin 22. The power supply unit 244 is connected to the power output port 23 provided in the corresponding storage bin 22. After the power supply unit 244 receives the processed DC signal (i.e., DC voltage) output by the power management unit 243, it can supply power to the recording and broadcasting equipment based on the DC signal. At this time, the power supply unit 244 can output the corresponding target power signal to the power output port 23. The target power signal can be considered as the power output after being transformed by the transformer and then processed by the peripheral circuit. The recording and broadcasting equipment receives the target power signal through the power output port 23 and charges the battery inside the recording and broadcasting equipment. Among them, the circuit interface and component parameters of each power supply unit 244 are not currently limited.

[0120] As mentioned above, when the external power supply signal is an AC signal, the surge protection unit can absorb the surge or peak voltage in the AC signal, the rectifier and filter unit can convert the AC signal into a DC signal that can be used as electrical energy, and the power management unit can realize functions such as electrical energy conversion for use by the power supply unit, thereby enabling each power supply unit to provide a higher quality target power supply signal to each recording and broadcasting device.

[0121] In one embodiment of the present application, reference Figure 5 When the monitoring module 25 is used to monitor the current value, the monitoring module 25 includes a current detection unit 251 and a central processing unit 252. The current detection unit 251 is used to obtain the current value of the target power signal sent by each power supply unit 244 to each power output port 23, and send each current value to the central processing unit 252. The central processing unit 252 is used to determine the recording and broadcasting equipment in a fully powered state according to each current value, and instruct the power supply unit 244 corresponding to the recording and broadcasting equipment in a fully powered state to shut down. Correspondingly, the power supply unit 244 is also used to shut down according to the instruction of the central processing unit 252, so as to stop providing the target power signal to the recording and broadcasting equipment in a fully powered state.

[0122] For example, during the charging process of the recording and broadcasting device, the current detection unit 251 in the monitoring module 25 collects the real-time current value of each target power signal, that is, the current detection unit 251 can detect the specific value of the current current of the target power signal. The specific structure and / or components included in the current detection unit 251 are not currently limited, and the existing technical solutions can be used, and only the current value needs to be measured.

[0123] The current detection unit 251 has multiple current input terminals, each of which is connected to an output terminal of a power supply unit 244, so that the current detection unit 251 obtains the target power signal output by each power supply unit 244. It can be understood that when the current detection unit 251 is connected to the output terminal of the power supply unit 244, it can be connected to any position in the line between the power supply unit 244 and the power output port 23, and only needs to obtain the target power signal. The power detection unit 251 can receive the real-time target power signal of each channel and determine the current value of each real-time target power signal.

[0124] The power detection unit 251 is also connected to the central processing unit 252 in the monitoring module 25, and the power detection unit 251 also sends the real-time current value of each target power signal to the central processing unit 252. The central processing unit 252 has calculation and control functions, and the central processing unit 252 can be a microcontroller unit (MCU) or a field programmable gate array (FPGA). When the central processing unit 252 receives the real-time current value of each target power signal, the current charging current of each recording and broadcasting device can be clearly determined. Afterwards, the central processing unit 252 can determine whether each recording and broadcasting device is fully charged based on the real-time current value of each target power signal. Among them, the central processing unit 252 pre-stores the preset current values ​​corresponding to each current value (i.e., the current value provided by the power supply when the recording and broadcasting device is in trickle charging). For example, the power detection unit 251 sends the current value of each target unit signal to the central processing unit 252 in a fixed order, and the central processing unit 252 pre-stores the preset current value corresponding to each position in the fixed order. At this time, after the central processing unit 252 receives the current value sent by the current detection unit 251, it can determine the corresponding preset current value based on the order received and the pre-stored fixed order. For another example, the central processing unit 252 pre-stores the identification and / or ID of each power supply unit 244 and other identity information that can distinguish each power supply unit 244, as well as the preset current value corresponding to the recording and broadcasting device corresponding to each power supply unit 244 (i.e., the current value provided by the power supply when the recording and broadcasting device is in trickle charging). When the power detection unit 251 sends the current value of each target power signal, it also sends the identity information. The central processing unit 252 can clarify the power units 244 and the corresponding recording and broadcasting equipment corresponding to each current value based on the identity information, and then determine the corresponding preset current value. In addition, the central processing unit 252 can also match the received current value with the corresponding power unit 244 or recording and broadcasting equipment in other ways.

[0125] At this time, when the central processing unit 252 determines that the real-time current value of a target power signal reaches the corresponding preset current value, it determines that the corresponding recording and broadcasting device is fully charged, that is, the current value meets the charging stop condition. In the embodiment, the fully charged recording and broadcasting device is recorded as a fully charged recording and broadcasting device.

[0126] The central processing unit 252 is also connected to each power supply unit 244. When the central processing unit 252 determines that the recording and broadcasting device is in a fully charged state (i.e., the current value meets the condition for stopping charging), it can send a signal to the corresponding power supply unit 244, which is used to instruct the power supply unit 243 to shut down. Optionally, the central processing unit 252 pre-stores the corresponding relationship between each preset current value and each power supply unit 244. When it is determined that the recording and broadcasting device is in a fully charged state, the central processing unit 252 can determine the power supply unit 244 corresponding to the recording and broadcasting device according to the currently used preset current value. Afterwards, the central processing unit 252 sends a signal for shutting down to the power supply unit 244 through the connection channel between the central processing unit 252 and the power supply unit 244.

[0127] Optionally, the power supply unit 244 includes a switch in addition to the necessary components for providing power, wherein the position of the switch in the power supply unit 244 can be set according to the actual circuit structure of the power supply unit 244, for example, a switch is set on the output line (i.e., the line providing the DC voltage as the power supply) of the winding of the transformer included in the power supply unit 244, and the switch can control the disconnection and connection of the output line. When the switch controls the output line to be disconnected, the power supply unit 244 is turned off (i.e., the channel with the corresponding power output port 23 is closed), and at this time, the power supply unit 244 stops working, i.e., no longer outputs the target power signal. When the switch controls the output line to be connected, the power supply unit 244 works normally, i.e., outputs the target power signal to the power output port 23. The switch in each power supply unit 244 is connected to the central processing unit 252, and at this time, the central processing unit 252 and the switch in each power supply unit 244 have corresponding connection channels to send a signal for closing to the power supply unit 244 through the connection channel. Among them, the signal for closing the channel can also be considered as a signal for the switch to close. In the embodiment, the central processing unit 252 can control the opening and closing of the switch. When the switch is turned on, the power supply unit 244 works normally, and when the switch is turned off, the power supply unit 224 stops working. The type of the switch and the way the central processing unit 252 controls the switch are not currently limited. For example, the switch is implemented by a MOS tube, and the central processing unit 252 controls the on and off of the MOS tube to realize the control of the on and off of the switch.

[0128] It can be understood that the power supply unit 244 has an interface connected to the power management unit 243, an interface connected to the power output port 23, and an interface connected to the central processing unit 252. Optionally, there is no need to additionally set up an interface connected to the current detection unit 251. The current detection unit 251 only needs to be connected to the connection line between the power supply unit 244 and the power output port 23.

[0129] In the above-mentioned technical means, the current value of each target power signal is detected by the current detection unit, the central processing unit determines whether the recording and broadcasting device is fully charged based on the current value, and instructs the power unit in the adapter module to turn off when the recording and broadcasting device is fully charged to stop providing the target power signal to the recording and broadcasting device. This realizes the real-time charging current monitoring of each recording and broadcasting device during the charging process of each recording and broadcasting device, so as to stop supplying power to the recording and broadcasting device when the recording and broadcasting device is fully charged, thereby reducing power consumption.

[0130] In one embodiment of the present application, reference Figure 6 The transfer compartment module 24 further includes: a circuit breaker unit 245. The central processing unit 252 is also used to control the circuit breaker unit 245 to start when it is determined that all recording and broadcasting devices are in a fully powered state; the circuit breaker unit 245 is used to disconnect the surge protection unit 241 from the power inlet 21 according to the control of the central processing unit 252, so as to stop providing the target power signal to all recording and broadcasting devices.

[0131] For example, when all recording and broadcasting devices are fully charged, the transfer compartment module 24 no longer needs to provide power to each recording and broadcasting device, and at this time, the transfer compartment module 24 does not need to work. Therefore, in order to further save power consumption, the connection between the transfer compartment module 24 and the power access port 21 can be disconnected to disconnect the external power signal.

[0132] In one embodiment, the switching compartment module 24 can disconnect the connection with the power access port 21 through the circuit breaker unit 245. At this time, the switching compartment module 24 may also include a circuit breaker unit 245. The circuit breaker unit 245 can be implemented by a circuit breaker, which is a commonly used device in the power field and is not described separately in the embodiment. The circuit breaker unit 245 is connected to the line between the surge protection unit 241 and the power access port 21, and the circuit breaker unit 245 can disconnect and close the line between the surge protection unit 241 and the power access port 21. Currently, the circuit breaker unit 245 is also connected to the central processing unit 252. When the central processing unit 252 determines that all the recording and broadcasting devices are fully charged, the circuit breaker unit 245 is controlled to start. After the circuit breaker unit 245 is started, the line between the surge protection unit 241 and the power access port 21 can be disconnected. At this time, the switching compartment module 24 cannot receive the external power signal, and the target power signal can be stopped from being provided to the recording and broadcasting device, which can be considered to stop the charging work.

[0133] Optionally, the circuit breaker unit 245 may be located inside the box 11, or on the inner surface or outer surface of the box 11. When the circuit breaker unit 245 is located on the inner surface or outer surface of the box 11, the user may manually control the circuit breaker unit 245 to start.

[0134] After the circuit breaker unit 254 is activated, it needs to be closed to restore the connection between the surge protection unit 241 and the power inlet 21. The closing method is not currently limited, for example, the circuit breaker unit 245 is closed manually, or when the power inlet 21 is connected to an external power signal again, the circuit breaker unit 245 is automatically closed.

[0135] As mentioned above, when all the recording and broadcasting devices are fully charged, the central processing unit 252 controls the circuit breaker unit 245 to start up to disconnect the line between the power inlet 21, that is, to stop receiving the external power signal. At this time, the recording and broadcasting device storage box no longer performs charging work to further save power consumption.

[0136] In one embodiment of the present application, reference Figure 7 When the monitoring module 25 is used to monitor the temperature value, the monitoring module 25 includes at least one temperature sensor 253, a temperature monitoring unit 254 and a central processing unit 252. The temperature sensor 253 is located in the box 11. The transfer bin module 24 also includes: a circuit breaker unit 245. Figure 7 The description is made by taking five temperature sensors 253 as an example.

[0137] The temperature monitoring unit 254 is used to obtain the temperature value collected by at least one temperature sensor 253 and send the temperature value to the central processing unit 252. The central processing unit 252 is used to control the circuit breaker unit 245 to start when it is determined that the cabinet 11 is in an abnormal temperature state according to the temperature value. The circuit breaker unit 245 is used to disconnect the surge protection unit 241 and the power inlet 21 according to the instruction of the central processing unit 252, so as to stop providing the target power signal to all recording and broadcasting devices.

[0138] Exemplarily, at least one temperature sensor 253 is also provided in the box 11, and the temperature sensor 253 can detect the temperature during the charging process of the recording and broadcasting device. Among them, the installation position of the temperature sensor 253 in the box can be determined in combination with the actual installation requirements. In one embodiment, each storage bin 22 corresponds to at least one temperature sensor 253, and the temperature sensor 253 collects the temperature in the corresponding storage bin 22. The number of temperature sensors 253 corresponding to each storage bin 22 can be determined according to the type of recording and broadcasting device stored in the storage bin 22. For example, when the recording and broadcasting device is a video acquisition device, the corresponding storage bin 22 corresponds to two temperature sensors 253, and the two temperature sensors 253 are used to detect the temperature of the storage bin. At this time, the temperature collected by the two temperature sensors 253 can reflect the charging heat consumption of the video acquisition device to a certain extent. When the recording and broadcasting device is an audio acquisition device, the corresponding storage bin 22 corresponds to one temperature sensor 253, and the temperature sensor 253 is used to detect the temperature of the storage bin. At this time, the temperature collected by the temperature sensor 253 can reflect the charging heat consumption of the audio acquisition device to a certain extent. When the recording and broadcasting device is a recording and broadcasting host, the corresponding storage bin 22 corresponds to a temperature sensor 253, and the temperature sensor 253 is used to detect the temperature of the storage bin. At this time, the temperature collected by the temperature sensor 253 can reflect the charging heat consumption of the recording and broadcasting host to a certain extent. The relative position between each temperature sensor 253 and the storage bin 22 is not currently limited.

[0139] In addition, at least one temperature sensor 253 may be provided for the transfer compartment module 24. In one embodiment, the temperature sensor 253 is used to collect the temperature of the power management unit 243. During the charging process of the recording and broadcasting equipment storage box 10, the temperature of the power management unit 243 of the transfer compartment module 24 is the highest. At this time, by collecting the temperature of the power management unit 243, the temperature of the transfer compartment module 24 in the box body 11 can be intuitively determined. When the transfer compartment module 24 supplies power to each recording and broadcasting device and other modules that need power supply (such as monitoring modules, prompt modules, etc.), the temperature of the power management unit 243 can reflect the size of the instantaneous power when the power is supplied. Generally speaking, one temperature sensor 253 can meet the need to collect the temperature of the power management unit 243. At this time, the relative position between the temperature sensor 253 and the power management unit 243 is not currently limited. Optionally, the temperature sensor 253 is set inside the box body 11 when installed, and the user will not see the temperature sensor when using the recording and broadcasting equipment storage box 10. The specific type and model of the temperature sensor 253 are not currently limited.

[0140] Each temperature sensor 253 is connected to the temperature monitoring unit 254 to convert the temperature it feels into a usable output signal and send it to the temperature monitoring unit 254. Afterwards, the temperature monitoring unit 254 obtains the temperature value collected by each temperature sensor 253 according to the signal output by each temperature sensor 253. Among them, the internal structure and component type of the temperature monitoring unit 254 are not currently limited. For example, the temperature monitoring unit 254 can be implemented by a programmable logic controller (PLC), and the programming language of the PLC can perform corresponding conversion and processing on the signal output by the temperature sensor 253 to obtain a signal that can represent the temperature value. Optionally, the temperature monitoring unit 254 can have multiple interfaces for input, each interface is connected to a temperature sensor 253, so as to receive the signal output by each temperature sensor 253 and obtain the temperature value collected by each temperature sensor 253.

[0141] The temperature monitoring unit 254 is also connected to the central processing unit 252. The central processing unit 252 can refer to the relevant description of the central processing unit 252. After the temperature monitoring unit 254 obtains the temperature values ​​collected by each temperature sensor 253, it can send each temperature value to the central processing unit 252.

[0142] The central processing unit 252 is also connected to the transfer compartment module 24 so as to control the transfer compartment module 24 to disconnect from the power inlet 21 when the temperature value meets the condition for stopping charging. Specifically, after the central processing unit 253 obtains each temperature value, if the temperature value reaches the preset temperature threshold, it can be considered that there is an area with too high temperature in the box 11. At this time, it can be considered that the box 11 is in an abnormal temperature state. In the abnormal temperature state, the modules and recording and broadcasting equipment in the box 11 may be damaged. In order to avoid such damage, the central processing unit 252 will control the transfer compartment module 24 to disconnect from the power inlet 21. In one embodiment, after the central processing unit 252 obtains each temperature value, as long as one of the temperature values ​​reaches the preset temperature threshold, it can be determined that the box 11 is in an abnormal temperature state.

[0143] Exemplarily, the switching compartment module 24 can be disconnected from the power inlet 21 by a circuit breaker unit 245. The circuit breaker unit 245 can refer to the related description of the circuit breaker unit 245. Optionally, when the user can manually control the circuit breaker unit 245 to be closed, if the user can feel the temperature of the box 11 drops, then the circuit breaker unit 245 can be manually controlled to be closed. After the circuit breaker unit 245 is closed, the switching compartment module 24 reconnects to the external power signal and charges the recording and broadcasting device.

[0144] As mentioned above, by arranging multiple temperature sensors inside the box, and obtaining the temperature value collected by each temperature sensor through the temperature monitoring unit, when the central processing unit determines that the box is in an abnormal temperature state based on each current value, the transfer compartment module is controlled to disconnect from the power inlet, so as to ensure charging safety during the charging process and avoid damage to the recording and broadcasting equipment storage box and the recording and broadcasting equipment due to excessive temperature.

[0145] refer to Figure 8 When the monitoring module 25 collects the temperature value and the current value at the same time, the monitoring module 25 includes a current detection unit 251, a central processing unit 252, at least one temperature sensor 253 and a temperature monitoring unit 254, and the transfer compartment module 24 includes a circuit breaker unit 245, a surge protection unit 241, a rectifier filter unit 242, a power management unit 243 and at least one power supply unit 244 ( Figure 8 The three power supply units 244 are taken as an example). The connection relationship and function of each unit can refer to the above content and are not limited at present.

[0146] In one embodiment of the present application, reference Fig. 9 The box 11 is also provided with a prompt module 26. The prompt module 26 is connected to the monitoring module 25. When monitoring the current value, the monitoring module 25 is also used to determine the current charging state of the recording and broadcasting device according to the current value, and to indicate the prompt module 26 to give a corresponding prompt according to the charging state. When monitoring the temperature value, the monitoring module 25 is also used to determine the high temperature state of the box according to the temperature value, and to indicate the prompt module 26 to give a corresponding prompt according to the high temperature state. The prompt module 26 is used to give a prompt according to the instruction of the monitoring module 25.

[0147] Exemplarily, the prompt module 26 is connected to the monitoring module 25, and can give prompts according to the instructions of the monitoring module 25. Optionally, the prompt module 26 is arranged on the inner surface of the box 11, and the user can see or hear the prompt of the prompt module 26 when using the recording and broadcasting equipment storage box. The prompt module 26 can be composed of at least one prompt light, a buzzer and / or an LED display screen.

[0148] In one embodiment, reference Fig.10 The prompt module 26 includes a plurality of prompt light groups 261 , each prompt light group 261 includes a plurality of prompt lights, each prompt light is arranged on the inner surface of the box body 11 , and each storage bin 22 has a corresponding prompt light group 261 .

[0149] Exemplarily, the number of indicator light groups 261 is consistent with the number of storage bins 22. In this case, each storage bin 22 has a corresponding indicator light group 261 to indicate the charging status and / or high temperature status of the recording and broadcasting equipment in the corresponding storage bin 22 through the indicator light group 261.

[0150] Each warning light group 261 includes a plurality of warning lights. Fig.10 Take for example that each indicator light group 261 includes 6 indicator lights. In the embodiment, the description is made on the assumption that each indicator light group 261 includes the same number of indicator lights. In actual applications, the number of indicator lights included in each indicator light group 261 may be different. The indicator lights may be controlled by the monitoring module 25. Specifically, the central processing unit 252 of the monitoring module 25 may control each indicator light to turn on and off respectively, and may also control the form in which the indicator lights are turned on, for example, controlling the indicator lights to flash at a certain frequency or to be always on. The model of the indicator lights is not currently limited.

[0151] The installation position of the warning light group 261 on the surface of the box body 11 is not limited at present, for example, Fig.10 In the embodiment, a corresponding warning light group 261 is installed around each storage bin 22 .

[0152] In one embodiment, when the monitoring module 25 obtains the current value of each target power signal, it can instruct the prompt module 26 to give a corresponding prompt according to the current value. Take the prompt module 26 including a prompt light group as an example. For example, when each storage bin 22 shares the same prompt light group 261 in the prompt module 26, the monitoring module 25 determines that each recording and broadcasting device is in a fully charged state according to the current current value of each target power signal, and can instruct the prompt module 26 to give a full power prompt. At this time, the user can clearly know that all recording and broadcasting devices are fully charged according to the prompt module 26. For another example, when each storage bin 22 corresponds to a different prompt light group 261 in the prompt module 26, when the monitoring module 25 determines that a certain recording and broadcasting device is in a fully charged state according to the current current value of each target power signal, it can instruct the prompt module 26 to indicate the prompt light group 261 corresponding to the storage bin 22 where the recording and broadcasting device is located to give a full power prompt, so that the user can clearly know which recording and broadcasting device is fully charged. In addition to prompting the full charge status, the monitoring module 25 can also determine other charging states during the charging process of the recording and broadcasting device according to the real-time current value of each target power supply signal, and instruct the prompt module 26 to give prompts so that the user can clearly understand the current charging progress of each recording and broadcasting device.

[0153] The charging state may reflect the current charging progress of the recording and broadcasting device. In one embodiment, the charging state of the recording and broadcasting device during charging may include a fast charging state, a constant voltage charging state, a trickle charging state, and a full charge state.

[0154] In the fast charging state, the battery power of the recording and broadcasting device is low. When charging, the recording and broadcasting device can be quickly charged through a relatively large charging current. At this time, the power in the battery of the recording and broadcasting device increases rapidly. When the battery power of the recording and broadcasting device reaches a certain proportion, that is, when the battery power is high, it will enter the constant voltage charging state from the fast charging state. For example, after the battery power reaches 80%, it can enter the constant voltage charging state. In the constant voltage charging state, the charging voltage continues to be at the maximum value, and the charging current gradually decreases. When the battery power reaches the critical state of being full, it enters the trickle charging state. In the trickle charging state, the battery power is close to full power. At this time, the battery can be charged by a small pulse current to ensure that the battery is truly saturated, that is, it reaches a full power state. The charging current of the recording and broadcasting device in the fast charging state is greater than the charging current of the recording and broadcasting device in the constant voltage charging state, and the charging current of the recording and broadcasting device in the constant voltage charging state is greater than the charging current of the recording and broadcasting device in the trickle charging state. The charging current of the recording and broadcasting device in the trickle charging state is greater than the charging current of the recording and broadcasting device in the full power state.

[0155] When each power supply unit 244 provides a target power signal, it specifically provides a target power signal in the current charging state. Accordingly, the central processing unit 252 pre-records the current value range or current value critical value corresponding to each recording and broadcasting device in each charging state. Afterwards, the central processing unit 252 can determine the current charging state of the recording and broadcasting device based on the acquired real-time current value and the current value range or current value critical value corresponding to each charging state, wherein the specific value of the current value range or current value critical value corresponding to each charging state is not currently limited. Afterwards, the central processing unit 252 indicates the element corresponding to the recording and broadcasting device in the prompt module 26 (such as the prompt light group 261) according to the current charging state of each recording and broadcasting device, wherein the prompting methods corresponding to different charging states are different, so that the user can clearly understand the current charging state of each recording and broadcasting device.

[0156] In one embodiment, when monitoring the current value, the monitoring module 25 prompts the charging status through the prompt light group 261. At this time, each prompt light group 261 includes three first prompt lights 2611. Among them, the first prompt light can be understood as a prompt light used to prompt the charging status. Each first prompt light displays the same color when it is lit. Currently, the color displayed when the first prompt light is lit is recorded as the first color.

[0157] The three first prompt lights cooperate with each other to provide prompts for fast charging status, constant voltage charging status, trickle charging status and full charge status.

[0158] In one embodiment, when the current charging state of the recording and broadcasting device is a fast charging state, the first first indicator light in the corresponding indicator light group 261 flashes a first color at a first frequency; when the current charging state of the recording and broadcasting device is a constant voltage charging state, the first first indicator light in the corresponding indicator light group 261 is always on in the first color, and the second first indicator light in the indicator light group 261 flashes a first color at a second frequency; when the current charging state of the recording and broadcasting device is a trickle charging state, the first first indicator light and the second first indicator light in the corresponding indicator light group 261 are always on in the first color, and the third first indicator light flashes a first color at a third frequency; when the current charging state of the recording and broadcasting device is a full charge state, the three first indicator lights in the corresponding indicator light group 261 are always on in the first color, and the current value of the corresponding target power signal of the recording and broadcasting device in the full charge state meets the condition for stopping charging.

[0159] Exemplarily, in each charging state, the central processing unit 252 controls the first indicator light 2611 in each indicator light group 261 in the same manner. Therefore, in the embodiment, taking the central processing unit 252 controlling the first indicator light 2611 in a indicator light group 261 as an example, how to indicate each charging state is described.

[0160] When the central processing unit 252 determines that the recording and broadcasting device is currently in a fast charging state based on the real-time current value of a target power supply signal, it controls one of the first prompt lights in the corresponding prompt light group 261 to flash, and the other two first prompt lights remain off. At present, the first prompt light flashing in the fast charging state is recorded as the first first prompt light. Among them, the first first prompt light can be the first prompt light located at the edge of the prompt light group 261. For example, when the three first prompt lights are arranged in a horizontal direction, the first prompt light located on the far left can be used as the first first prompt light. For another example, when the three first prompt lights are arranged in a vertical direction, the first prompt light located at the bottom can be used as the first first prompt light. The first first prompt light displays a first color when it flashes. Optionally, the central processing unit 252 can control the first first prompt light to flash according to a first frequency. Among them, the specific value of the first frequency is not currently limited.

[0161] When the central processing unit 252 determines that the recording and broadcasting device is currently in a constant voltage charging state according to the real-time current value of a target power supply signal, it controls the first first prompt light in the corresponding prompt light group 261 to be always on, controls another first prompt light to flash, and keeps the remaining first prompt light off. At present, the first prompt light flashing in the constant voltage charging state is recorded as the second first prompt light. Among them, the second first prompt light can be the first prompt light adjacent to the first first prompt light in the prompt light group 261. For example, when the three first prompt lights are arranged in a horizontal direction, the middle prompt light can be used as the second first prompt light. For another example, when the three first prompt lights are arranged in a vertical direction, the middle prompt light can be used as the second first prompt light. The second first prompt light displays the first color when it flashes. The first first prompt light is always on the first color and no longer flashes. Optionally, the central processing unit 252 can control the second first prompt light to flash according to the second frequency, and control the first first prompt light to be always on the first color. Among them, the specific value of the second frequency is not currently limited, and the second frequency and the first frequency can be the same or different.

[0162] When the central processing unit 252 determines that the recording and broadcasting device is currently in a trickle charging state based on the real-time current value of a target power supply signal, it controls the first first prompt light and the second first prompt light in the corresponding prompt light group 261 to be always on, and the remaining first prompt light to flash. At present, the first prompt light that flashes in the trickle charging state is recorded as the third first prompt light. Among them, the third first prompt light is the first prompt light remaining in the prompt light group 261 except the first first prompt light and the second first prompt light. The third first prompt light displays the first color when it flashes. The first first prompt light and the second first prompt light are always on the first color and no longer flash. Optionally, the central processing unit 252 can control the third first prompt light to flash according to the third frequency, and control the first first prompt light and the second first prompt light to be always on. Among them, the specific value of the third frequency is not currently limited, and the third frequency can be the same as or different from the second frequency and the first frequency.

[0163] When the central processing unit 252 determines that the recording and broadcasting device is currently in a fully charged state according to the real-time current value of the target power supply signal, it controls the three first prompt lights in the corresponding prompt light group 261 to be always on. At this time, the three first prompt lights are always on in the first color and no longer flash. It can be understood that when the device is in a fully charged state, the central processing unit 252 can determine that the charging stop condition is met and instruct the corresponding power supply unit 244 to shut down so that the recording and broadcasting device no longer receives the charging current.

[0164] At this time, the prompt light group 261 can be lit one by one from one side to the other side, so that the user can better understand the charging status of the current recording and broadcasting device.

[0165] It is understandable that other numbers of first warning lights may be provided in the warning light group 261, and other lighting rules may be adopted for the first warning lights in different charging states.

[0166] In one embodiment, when monitoring the temperature value, the monitoring module 25 can also instruct the prompt module 26 to give a corresponding prompt according to the temperature value. Take the prompt module 26 including a prompt light group as an example. For example, when each storage bin 22 shares the same prompt light group 261 in the prompt module 26, when the monitoring module 25 determines that the temperature in the box 11 is in an abnormal state according to each temperature value, it can instruct the prompt module 26 to give a prompt of the abnormal temperature state. At this time, the user can clearly understand the temperature abnormality according to the prompt module 26. For another example, when each storage bin 22 corresponds to a different prompt light group 261 in the prompt module 26, when the monitoring module 25 determines that a certain storage bin 22 is in an abnormal temperature state according to each temperature value, it can instruct the prompt module 26 to give a prompt corresponding to the storage bin 22, so that the user can clearly understand which storage bin 22 has an abnormal temperature. In addition to prompting the abnormal temperature state, the monitoring module 25 can also determine the various high temperature states during the charging process of the recording and broadcasting device, and instruct the prompt module 26 to give a prompt, so that the user can clearly understand the current high temperature state.

[0167] Among them, the high temperature state refers to the temperature state when the temperature in the box 11 is high but has not reached the temperature abnormal state. In one embodiment, during the charging process of the recording and broadcasting device, the high temperature state may include a first high temperature state, a second high temperature state, a third high temperature state and a fourth high temperature state. Among them, the temperature value range of the second high temperature state is adjacent to the temperature value range of the first high temperature state and the temperature value range of the second high temperature state is greater than the temperature value range of the first high temperature state, the temperature value range of the third high temperature state is adjacent to the temperature value range of the second high temperature state and the temperature value range of the third high temperature state is greater than the temperature value range of the second high temperature state, the temperature value range of the fourth high temperature state is adjacent to the temperature value range of the third high temperature state and the temperature value range of the fourth high temperature state is greater than the temperature value range of the third high temperature state, and the temperature threshold corresponding to the temperature abnormal state is equal to the maximum temperature value in the temperature value range of the fourth high temperature state. Among them, the temperature value range corresponding to each high temperature state is not currently limited. For example, the temperature value range of the first high temperature state is [T0, T1), the temperature value range of the second high temperature state is [T1, T2), the temperature value range of the third high temperature state is [T2, T3), the temperature value range of the fourth high temperature state is [T3, T4), the temperature threshold of the temperature abnormal state is T4, and T4>T3>T2>T1>T0.

[0168] The temperature value range corresponding to each high temperature state and the temperature threshold corresponding to the temperature abnormal state are pre-recorded in the central processing unit 252. Afterwards, the central processing unit 252 can determine the high temperature state or temperature abnormal state around the location of the corresponding temperature sensor according to the acquired temperature value and each temperature value range. Afterwards, the central processing unit 252 gives a corresponding prompt according to the high temperature state indication prompt module 26.

[0169] In one embodiment, the central processing unit 252 can respectively determine the current high temperature state of each storage bin 22 (it can also reflect the current high temperature state of the recording and broadcasting equipment), and then, according to the high temperature state of each storage bin 22, the indicator light group 261 corresponding to the storage bin 22 in the control prompt module 26 is given a corresponding prompt, wherein different high temperature electrical states correspond to different prompt methods, so that the user can clearly understand the current high temperature state of each storage bin 22.

[0170] When the monitoring module monitors the temperature value, the temperature value includes the first temperature value corresponding to each storage bin, and each indicator light group includes three second indicator lights 2612. When the first temperature value corresponds to the first high temperature state, one second indicator light in the corresponding indicator light group 261 flashes the second color at the fourth frequency. When the first temperature value corresponds to the second high temperature state, two second indicator lights in the corresponding indicator light group 261 flash the second color at the fifth frequency. When the first temperature value corresponds to the third high temperature state, three second indicator lights in the corresponding indicator light group 261 flash the second color at the sixth frequency. When the first temperature value corresponds to the fourth high temperature state, the three second indicator lights in the corresponding indicator light group 261 are always on the second color. When the first temperature value corresponds to the abnormal temperature state, the first temperature value meets the condition for stopping charging, and the three second indicator lights in the corresponding indicator light group 261 are all off.

[0171] The second prompt light can be understood as a prompt light used to prompt a high temperature state, and the first prompt light and the second prompt light are different prompt lights. When the prompt light group 261 can provide high temperature state prompts and charging state prompts, it includes three first prompt lights and three second prompt lights. Each second prompt light displays the same color when it is lit. Currently, the color displayed when the second prompt light is lit is recorded as the second color. The second color is different from the first color so that the user can clearly understand the charging prompt and the high temperature prompt. After the three second prompt lights cooperate with each other, prompts for the first high temperature state, the second high temperature state, the third high temperature state and the fourth high temperature state can be realized.

[0172] Currently, each storage bin 22 is configured with a corresponding temperature sensor, and the real-time temperature value of each storage bin 22 can be obtained based on the temperature sensor. Among them, the number of temperature sensors configured in different storage bins 22 can be the same or different. For example, the storage bin 22 storing the video acquisition device is configured with two temperature sensors, the storage bin 22 storing the audio acquisition device is configured with one temperature sensor, and the storage bin 22 storing the recording and broadcasting host is configured with one temperature sensor. In the embodiment, the temperature value of the storage bin 22 collected is recorded as the first temperature value. The central processing unit 252 can determine the high temperature state of each storage bin 22 according to each first temperature value, and instruct the corresponding prompt light group to give a prompt.

[0173] Exemplarily, under each high temperature state, the central processing unit 252 controls the second indicator light 2612 in each indicator light group 261 in the same manner. Therefore, in the embodiment, taking the central processing unit 252 controlling the second indicator light 2612 in a indicator light group 261 as an example, how to provide a prompt for each high temperature state is described.

[0174] When the central processing unit 252 determines that the real-time first temperature value of a storage bin 22 is within the temperature value range of the first high temperature state, it determines that the first temperature value corresponds to the first high temperature state. At this time, it can be considered that the temperature of the storage bin 22 has left the comfort zone. Among them, the temperature value range of the comfort zone is lower than the temperature value range of the first high temperature state, and the indicator light group 261 in the comfort zone does not indicate the high temperature state and is in an off state. When the temperature value is in the comfort zone, it means that the temperature of the box 11 is normal. When the central processing unit 252 determines that the first temperature value corresponds to the first high temperature state, it controls one of the second indicator lights in the corresponding indicator light group 261 to flash, and the other two second indicator lights remain off. Among them, in the first high temperature state, the flashing second indicator light can be the second indicator light located at the edge of the indicator light group 261. For example, when the three second indicator lights are arranged in the horizontal direction, the second indicator light located on the far right can be used as the flashing second indicator light in the first high temperature state. For another example, when the three second indicator lights are arranged in the vertical direction, the second indicator light located on the uppermost side can be used as the flashing second indicator light in the first high temperature state. The second indicator light displays the second color when it flashes. Optionally, in the first high temperature state, the central processing unit 252 may control a second prompt light to flash according to a fourth frequency, wherein the specific value of the fourth frequency is not currently limited.

[0175] When the central processing unit 252 determines that the first temperature value continues to rise and is within the temperature value range of the second high temperature state, it determines that the first temperature value corresponds to the second high temperature state. At this time, the central processing unit 252 controls the two second indicator lights in the corresponding indicator light group 261 to flash, and the other second indicator light remains off. In the second high temperature state, the two flashing second indicator lights can be two adjacent second indicator lights in the indicator light group 261, and optionally, the two flashing second indicator lights include the second indicator lights flashing in the first high temperature state. For example, when the three second indicator lights are arranged in the horizontal direction, the two second indicator lights located on the far right and in the middle can be used as the second indicator lights flashing in the second high temperature state. For another example, when the three second indicator lights are arranged in the vertical direction, the two second indicator lights located on the uppermost side and in the middle can be used as the second indicator lights flashing in the second high temperature state. The second indicator light displays the second color when it flashes. Optionally, in the second high temperature state, the central processing unit 252 can control the two second indicator lights to flash according to the fifth frequency, and the specific value of the fifth frequency is not currently limited, wherein the fifth frequency and the fourth frequency can be the same or different.

[0176] When the central processing unit 252 determines that the first temperature value continues to rise and is within the temperature value range of the third high temperature state, it is determined that the first temperature value corresponds to the third high temperature state. At this time, the central processing unit 252 controls the three second prompt lights in the corresponding prompt light group 261 to flash. The three second prompt lights display the second color when flashing. Optionally, in the third high temperature state, the central processing unit 252 can control the three second prompt lights to flash according to the sixth frequency. Among them, the specific value of the sixth frequency is not currently limited, and the sixth frequency can be the same as or different from the fifth frequency and the fourth frequency.

[0177] When the central processing unit 252 determines that the first temperature value continues to rise and is within the temperature value range of the fourth high temperature state, it determines that the first temperature value corresponds to the fourth high temperature state. At this time, the central processing unit 252 controls the three second prompt lights in the corresponding prompt light group 261 to be always on. When the three second prompt lights are always on, they display the second color.

[0178] When the first temperature value reaches the temperature threshold corresponding to the temperature abnormal state, the central processing unit 252 determines that the first temperature value corresponds to the temperature abnormal state. At this time, the central processing unit 252 instructs the transfer compartment module 24 to disconnect from the power inlet 21. After the disconnection, there is no external power signal input. At this time, all second prompt lights are off.

[0179] It should be noted that if the storage bin 22 corresponds to multiple temperature sensors, the central processing unit 252 selects the highest temperature value from the temperature values ​​collected by the temperature sensor corresponding to the storage bin 22 to determine the high temperature state.

[0180] It is understandable that other numbers of second warning lights may be provided in the warning light group 261, and other lighting rules may be adopted for the second warning lights under different temperature conditions.

[0181] In one embodiment, the temperature value also includes a second temperature value of the power management unit 243; when the second temperature value corresponds to a fourth high temperature state, the three second indicator lights in each indicator light group are always on in a second color; when the second temperature value corresponds to an abnormal temperature state, the second temperature value meets the condition for stopping charging, and the three second indicator lights in each indicator light group are off.

[0182] In addition to configuring a temperature sensor for each storage bin 22, a temperature sensor is also configured for the power management unit 243, which can intuitively reflect the temperature inside the box. Currently, the temperature value obtained based on the temperature sensor configured based on the power management unit 243 is recorded as the second temperature value. When the central processing unit 252 receives the second temperature value, it determines that the second temperature value reaches the fourth high temperature state, and controls the three second prompt lights 2612 in each prompt light group 261 to be always on. Each second prompt light displays a second color when it is always on. Optionally, when the second temperature value reaches the temperature threshold corresponding to the temperature abnormality state, the central processing unit 252 determines that the second temperature value satisfies the temperature abnormality state. At this time, the central processing unit 252 instructs the transfer bin module 24 to disconnect from the power inlet 21, and each second prompt light 2612 is turned off.

[0183] Optionally, the central processing unit 252 may also determine the first high temperature state to the third high temperature state corresponding to the second temperature value, but does not control the prompt module 26 to give a prompt. Because when the second temperature value corresponds to the first high temperature state to the third high temperature state, the recording and broadcasting device storage box and the recording and broadcasting device are still in a relatively safe charging environment.

[0184] In one embodiment of the present application, the prompt module 26 further includes a buzzer 2613, and the buzzer 2613 is used to play a warning sound when the fourth high temperature state occurs.

[0185] Exemplarily, the prompt module 26 also includes a buzzer 2613, and the number of the buzzer 2613 can also be one or more. In the embodiment, the buzzer is described as one for example. The buzzer 2613 is installed on the inner surface of the box 11. In one embodiment, the central processing unit 252 is also connected to the buzzer 2613. When the central processing unit 252 determines that one of the temperature values ​​corresponds to the fourth high temperature state, the buzzer is activated to make the buzzer sound to prompt the user that the current temperature of the box is high. At this time, the user can determine which recording and broadcasting device has a higher temperature or determine that the temperature inside the box is higher according to the second prompt light.

[0186] As mentioned above, each charging status and / or each high temperature status can be prompted through the prompt module. In addition, when the prompt module includes multiple prompt light groups and each storage bin has a corresponding prompt light group, the charging status and / or high temperature status of the recording and broadcasting equipment in each storage bin can be prompted separately. In addition, different prompt lights are used to prompt the charging status and high temperature status, so that the user can clearly understand the charging status and high temperature status at the same time. In addition, different high temperature statuses can be set according to actual conditions, and the high temperature status can be prompted more reasonably. By setting a buzzer, the user can be more clearly prompted when the temperature value is about to reach the abnormal temperature state, thereby further ensuring the charging safety.

[0187] The following is an exemplary description of the storage box for recording and broadcasting equipment provided in the embodiment of the present application. Fig.11 The power supply inlet 21 is a three-phase AC power supply inlet, and the three storage compartments 22 store the recording and broadcasting host, the microphone and the camera respectively. There are five temperature sensors 253, among which the storage compartment 22 corresponding to the recording and broadcasting host and the storage compartment 22 corresponding to the microphone are respectively provided with temperature sensors 4 and 5, the storage compartment 22 corresponding to the camera is provided with temperature sensors 2 and 3, and the power management unit 243 is provided with a temperature sensor 1. The threshold corresponding to the abnormal temperature state is T4, the temperature value range of the first high temperature state is [T0, T1), the temperature value range of the second high temperature state is [T1, T2), the temperature value range of the third high temperature state is [T2, T3), and the temperature value range of the fourth high temperature state is [T3, T4). The prompt module 26 (connected to the central processing unit 252) includes three prompt light groups, each prompt light group includes 6 prompt lights, among which 3 prompt lights flash blue when they are lit, as the first prompt lights, and 3 prompt lights flash red when they are lit, as the second prompt lights.

[0188] When three recording and broadcasting devices are placed in the storage compartment 22 and the power inlet 21 is connected to an external power signal, each recording and broadcasting device can be charged.

[0189] Taking the recording and broadcasting host as an example, the corresponding three first prompt lights are arranged horizontally, and the three second prompt lights are arranged horizontally. In the fast charging state, the current value of the charging current required by the recording and broadcasting host is recorded as I12, in the constant voltage charging state, the current value of the charging current required by the recording and broadcasting host is recorded as I11, and in the trickle charging state, the current value of the charging current required by the recording and broadcasting host is recorded as I10.

[0190] At present, when the recording and broadcasting host is charging, the central processing unit 252 obtains the real-time current value of the target power signal corresponding to the recording and broadcasting host, which is currently recorded as I1. When I1=I12, it is determined that the recording and broadcasting host is in a fast charging state. At this time, the first prompt light on the far left flashes blue, and the flashing frequency is recorded as f3. When I1=I11, it is determined that the recording and broadcasting host is in a constant voltage charging state. At this time, the first prompt light on the far left is always on, and the first prompt light in the middle flashes blue, and the flashing frequency is recorded as f2. When I1=I10, it is determined that the recording and broadcasting host is in a trickle charging state. At this time, the first prompt light on the far left and the first prompt light in the middle are always on, and the first prompt light on the right flashes blue, and the flashing frequency is recorded as f1. f1=f2=f3, or, f1<f2<f3. When I1<I10, the corresponding power supply unit is controlled to be turned off, and at this time, the recording and broadcasting host is no longer charged.

[0191] Optionally, when the three recording and broadcasting devices are fully charged, the central processing unit 252 turns on the circuit breaker unit to disconnect the external power signal.

[0192] When the recording and broadcasting host is charging, the temperature value collected by the temperature sensor 4 is recorded as T. When the central processing unit 252 determines that T is in the comfort zone (i.e. <T0), the second prompt light will not be turned on. When it is determined that T0≤T<T1, it is determined that the recording and broadcasting host is in the first high temperature state, and the second prompt light on the right flashes red. When it is determined that T1≤T<T2, it is determined that the recording and broadcasting host is in the second high temperature state, and the second prompt lights on the right and in the middle flash red. When it is determined that T2≤T<T3, it is determined that the recording and broadcasting host is in the third high temperature state, and the three second prompt lights flash red. When it is determined that T3≤T<T4, it is determined that the recording and broadcasting host is in the fourth high temperature state, and the three second prompt lights are always on red, and when the buzzer is configured, the buzzer is controlled to emit an alarm sound. When it is determined that T4≤T, the circuit breaker unit is turned on to disconnect the external power signal.

[0193] In the above, each recording and broadcasting device in the storage box can be charged, and during charging, the charging state and high temperature state can be prompted. When the battery is fully charged or the temperature is abnormal, the power supply to the recording and broadcasting device is stopped, thereby ensuring charging safety.
