Abstract

The invention discloses a control device and a control system used for a power source. The device comprises a first wiring terminal platform, a second wiring terminal platform and at least two reverse isolation units, wherein the first wiring terminal platform comprises at least two groups of power input terminals, and electric energy inputted by one power source is respectively received by first ends of each group of power input terminals; the second wiring terminal platform comprises at least two groups of power output terminals, electric energy is outputted to one terminal respectively by first ends of each group of power output terminals, and second ends of each group of power output terminals are connected in parallel at a first node through cascade wires; and a first end of each reverse isolation unit is connected with the second end of one power input terminal, a second end of each reverse isolation unit is connected with each other in parallel at a second node, and the first node is connected with the second node. According to the control device used for the power source and the system, while the electric energy can be provided for a display unit of which the power source fails, the size and the cost of the display unit are not increased.

Description

technical field [0001] The invention relates to the field of control, in particular to a control device and system for a power supply. Background technique [0002] Existing display units are generally powered by a single power supply. Once the power supply of the display unit fails, the display unit will display failure, which will also lead to the disconnection of the downward cascading signal channel, and the independent display unit will fail due to power failure. It may cause a large-area display unit to fail to work, and the visual effect of the system will also deteriorate. At present, people mainly use n+1 power supply with redundant function to solve this problem, that is, add a power supply to a display unit, and connect the power supplies in parallel. When one power supply fails, the backup power supply can be used. Enable power supply output. [0003] However, if the above solution is adopted, adding a set of backup power supply will increase the size of the di...
