[0043] In some embodiments, such as Figure 1As shown, a power supply device for the Conference Treasure 2 is provided. The power supply device for the Conference Treasure 2 includes an AC-DC power supply 1 and the Conference Treasure 2: The AC-DC power supply 1 is connected to the Conference Treasure 2, and the AC-DC power supply 1 is used to convert mains power into direct current and supply direct current to the Conference Treasure 2; The Conference Treasure 2 includes: a local main control unit 3, the local main control unit 3 is connected to a series cascade power control module 4, and is used to monitor and control the series cascade power control module 4; The series cascade power control module 4, the series cascade power control module 4 is connected to the series cascade power supply 5, and is used to monitor and control the series cascade power supply 5 and feed back the monitoring data of the series cascade power supply 5 to the local main control unit 3; The series cascade power supply 5 is used to supply power to its subordinate devices; The subordinate device is another Conference Treasure 6.
[0044] Optionally, the local main control unit 3 is specifically used for: sending a series cascade power control instruction to the series cascade power control module 4; obtaining the current value fed back by the series cascade power control module 4; based on the current value, regenerating a series cascade power control instruction and sending the series cascade power control instruction to the series cascade power control module 4.
[0045] Optionally, sending a series cascade power control instruction to the series cascade power control module 4 includes: sending a series cascade power on instruction to the series cascade power control module 4 at a preset frequency.
[0046] Optionally, regenerating a series cascade power control instruction and sending the series cascade power control instruction to the series cascade power control module 4 includes: if the current value is less than or equal to a preset current threshold, generating a series cascade power off instruction and sending the series cascade power off instruction to the series cascade power control module 4; if the current value is greater than the preset current threshold, no series cascade power control instruction is generated.
[0047] Optionally, regenerating a series cascade power control instruction and sending the series cascade power control instruction to the series cascade power control module 4 includes: if the current value is less than or equal to a preset current threshold, generating a series cascade power off instruction and sending the series cascade power off instruction to the series cascade power control module 4; if the current value is greater than the preset current threshold, no series cascade power control instruction is generated.
[0048] Optionally, the conference device 2 further includes: a local power management module 7, which is respectively connected to the AC-DC power supply 1, the local main control unit 3, the series cascade power control module 4, and the series cascade power supply 5; the local power management module 7 is configured to distribute the direct current power and supply power to the AC-DC power supply 1, the local main control unit 3, the series cascade power control module 4, and the series cascade power supply 5.
[0049] Optionally, the conference device 2 further includes: a first interface 8, which is arranged on the local power management module 7, and the first interface 8 is used to connect the AC-DC power supply 1.
[0050] Optionally, the conference device 2 further includes: a second interface 9, which is arranged on the series cascade power supply 5, and the second interface 9 is used to connect the other conference device 6.
[0051] Optionally, the structure of the other conference device 6 is the same as that of the conference device 2.
[0052] Optionally, the first interface 8 of the other conference device 6 is also used to connect the second interface 9 of the conference device 2.
[0053] Exemplarily, the conference device 2 can be connected to the mains power through the AC-DC power supply 1. For example, the AC-DC power supply 1 is connected to a 220V AC power socket through a plug. The AC-DC power supply 1 is connected to the first conference device 2 through the first interface 8. After converting the AC power into DC power, it supplies power to the first conference device 2. The local power management module 7 will distribute the DC power to supply power to the local main control unit 3, the series cascade power control module 4, and the series cascade power supply 5 respectively. In addition to controlling the operation of the conference device 2, the local main control unit 3 will also send a series cascade power-on command to the series cascade power control module 4 at a certain frequency (for example, once per second). After receiving the series cascade power-on command, the series cascade power control module 4 will control the series cascade power supply 5 to turn on. At this time, the series cascade power control module 4 will monitor the current value of the series cascade power supply 5 in real time and feedback the current value to the local main control unit 3. At this time, if the second interface 9 is not connected to other conference devices 6, the current of the series cascade power supply 5 is extremely small or 0. That is, when the current value is less than or equal to the preset current threshold, the local main control unit 3 will determine that the second interface 9 is not connected to other conference devices 6 at this time. Subsequently, the local main control unit 3 will send a series cascade power-off command to the series cascade power control module 4, and the series cascade power control module 4 will control the series cascade power supply 5 to turn off. If the second interface 9 is connected to other conference devices 6 at this time, the current of the series cascade power supply 5 will be relatively large. When the local main control unit 3 receives this current value and finds that the current value is greater than the preset current threshold, it will determine that there are other conference devices 6 connected at this time, and thus will not send a command to the series cascade power control module 4, so as to maintain the on state of the series cascade power supply 5. When other conference devices 6 are no longer in use and are unplugged from the second interface 9, the current value of the series cascade power supply 5 will drop to a level lower than the preset current threshold again. At this time, the local main control unit 3 can still judge according to the magnitude of the current value that there are no other conference devices 6 connected at this time. Subsequently, a series cascade power-off command is generated and sent to the series cascade power control module 4, and the series cascade power control module 4 will control the series cascade power supply 5 to turn off.
[0054] And so on, the second interface 9 of the first conference device 2 can be connected to the first interface 8 of the second conference device 2, and the second interface 9 of the second conference device 2 can be connected to the first interface 8 of the third conference device 2, so as to realize power supply for multiple conference devices 2.
[0055] It should be noted that since the main control unit sends a series cascade power-on command to the series cascade power control module 4 at a certain frequency (for example, once per second), when other meeting devices 6 are connected, they may be in the state where the series cascade power supply 5 is turned off. At this time, the newly connected other meeting devices 6 cannot be powered immediately, but they only need to wait for up to 1 second to get powered. The waiting time is related to the set frequency, and the corresponding frequency can be set according to specific usage requirements.
[0056] The power supply device for the meeting device 2 in the above embodiment includes an AC-DC power supply 1 and the meeting device 2: The AC-DC power supply 1 is connected to the meeting device 2 and is used to convert commercial power into direct current and provide direct current to the meeting device 2; The meeting device 2 includes: a local main control unit 3, which is connected to the series cascade power control module 4 and is used to monitor and control the series cascade power control module 4; A series cascade power control module 4, which is connected to the series cascade power supply 5 and is used to monitor and control the series cascade power supply 5 and feed back the monitoring data of the series cascade power supply 5 to the local main control unit 3; The series cascade power supply 5 is used to supply power to its subordinate devices; The subordinate device is other meeting devices 6. Only one meeting device 2 needs to be connected to the commercial power, and other meeting devices 6 only need to be connected to the series cascade power supply 5 of the previous meeting device 2 in sequence, then the simultaneous power supply to multiple meeting devices 2 can be realized, without the need for complex circuit deployment, achieving the goal of significantly reducing the deployment difficulty and cost while realizing the power supply to multiple meeting devices 2.
[0057] The technical features of the above embodiments can be arbitrarily integrated. For the sake of brevity of description, not all possible integrations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the integration of these technical features, it should be considered as the scope recorded in this specification.
[0058] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
