Technical Field
The application relates to the technical field of power supply control, in particular to a centralized power supply device.
Background
In video transmission, a plurality of display screens and a plurality of coding and decoding devices are generally arranged in a scene. In order to manage a plurality of codec devices, a power adapter with a certain power is generally used to supply power to the codec devices, for example, a plurality of 12V power adapters are used to supply power to a plurality of codec devices respectively. For unified management, a timing power source or a multi-hole socket is generally used for management.
For a time sequence power supply, the multi-channel single switch or simultaneous switch can be realized, and the unified management is convenient to carry out. However, due to the large size and weight of the sequential power supply equipment, the sequential power supply equipment can only be placed at a specific position, namely, the sequential power supply equipment needs to be placed in a cabinet, so that the whole video system needs to be arranged around the sequential power supply. Furthermore, since the devices may not be in the same cabinet, additional extension cords are required to connect the devices to the sequential power supply. Due to long-term exposure in the external environment, the extension line is easy to damage and is not easy to arrange.
For a multi-porous patch, it can be placed anywhere in the scene. However, the multi-hole socket can only realize simultaneous power-on and power-off, and cannot realize multi-channel independent switch. In addition, the safety performance of the multi-hole socket is poor, and under the condition that a plurality of devices are powered on simultaneously, the instantaneous current of the multi-hole socket is large, so that the multi-hole socket is easily damaged after repeated times. Further, since the voltage of each hole site of the multi-hole site socket is 220V, a plurality of 12V power adapters need to be provided, thereby preventing the problem that the high voltage damages the equipment. The equipment of a plurality of power adapters can bring the winding of power cord, is unfavorable for the later maintenance.
At present, no effective solution is provided for the problem that the codec device cannot be uniformly managed due to the need of configuring an additional power adapter in the related art.
