[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

DETAILED DESCRIPTION

[0017] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0018] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0019] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0020] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0021] The existing power switching control device can refer to Figure 1In the example shown, one end of switch 1 in the device is connected to the first power source, and the other end is connected to the input port of the power switching module. One end of switch 2 is connected to the second power source, and the other end is connected to the input port of the power switching module. The output port of the power switching module can output voltage to power the load device. Figure 1 In the circuit shown, only one power supply can supply power to the load device at the same time.

[0022] When switch 1 is connected, switch 2 needs to be disconnected, and the first power supply supplies power to the load device. If it is necessary to switch to the second power supply later, the power switching module needs to control switch 1 to disconnect first, and then control switch 2 to connect, and the second power supply supplies power to the load device. If it is switched to the first power supply again, the power switching module first controls the switch to disconnect, and then controls switch 1 to connect, and the first power supply supplies power to the load device. There will be a short power-off period during the switch switching process, and the load device cannot work during this period.

[0023] In response to the above problems, an embodiment of the present application provides a dual power supply switching control device. By setting a redundant module, the dual power supplies can be connected at the same time when the dual power supplies are switched, ensuring that the load equipment is continuously powered on and improving data security.

[0024] The device is provided with a redundancy module between the power supply and the load device, and the redundancy module is provided with a first input port and a second input port, and the first input port and the second input port are connected to the first power supply and the second power supply respectively. The redundancy module is also provided with an output port, and when any input port of the redundancy module is powered by power, the output port of the redundancy module outputs a DC voltage to power the load device. After the redundancy module is provided, the two power supplies can be supplied at the same time. In the power supply switching scenario, there is no need to disconnect the power supply being supplied first, which can avoid power failure during power switching.

[0025] The device is also provided with a power supply module, specifically including: a first power supply module and a second power supply module. The input of the first power supply module is connected to the first power supply, and the output of the first power supply module is connected to the first input port of the redundant module. The input of the second power supply module is connected to the second power supply, and the output of the second power supply module is connected to the second input port of the redundant module. The first power supply module can convert the AC voltage output by the first power supply into a DC voltage and output the DC voltage to the first input port of the redundant module, and the second power supply module can convert the AC voltage output by the second power supply into a DC voltage and output the DC voltage to the second input port of the redundant module. A first switch is provided between the first power supply and the first power supply module, and a second switch is provided between the second power supply and the second power supply module.

[0026] Figure 2 This is a schematic diagram of the structure of another dual power switching control device provided in an embodiment of the present application. Figure 2As shown, the device may include: a first power supply, a second power supply, a power switching module, a first power supply module, a second power supply module, a redundant module, a load device, a switch 1, a switch 2, a switch 3, and a switch 4. The first power supply is connected to the first power supply module through switch 1 and switch 3, and the first power supply module converts the AC voltage into a DC voltage and outputs it to the input port 1 (i.e., the first input port) of the redundant module. The second power supply is connected to the second power supply module through switch 2 and switch 4, and the second power supply module converts the AC voltage into a DC voltage and outputs it to the input port 2 (i.e., the second input port) of the redundant module. When at least one input port of the redundant module is connected to the power supply, its output port can output a DC voltage to power the load device. Switch 1 and switch 3 can be regarded as the first switch, and switch 2 and switch 4 can be regarded as the second switch.

[0027] In an optional embodiment, when two power supplies are supplied at the same time, switch 1, switch 2, switch 3 and switch 4 are all connected. The first power supply is connected to the first power supply module through switch 1 and switch 3, and the first power supply module outputs a DC voltage to the input port 1 of the redundant module. The second power supply is connected to the second power supply module through switch 2 and switch 4, and the second power supply module outputs a DC voltage to the input port 2 of the redundant module. The output port of the redundant module continuously outputs a DC voltage to power the load device. Optionally, the load device may include a device such as a controller that requires direct voltage supply.

[0028] In an optional embodiment, in a scenario where two power supplies are simultaneously powered, if the first power supply is powered off, the first power supply module cannot receive the AC voltage and cannot output the DC voltage to the redundant module. At this time, the second power supply still outputs the AC voltage to the second power supply module, and the second power supply module outputs the DC voltage to the input port 2 of the redundant module. In this scenario, the output port of the redundant module can still continuously output the DC voltage to power the load device. If the first power supply is restored, the first power supply module can receive the AC voltage and then output the DC voltage to the input port 1 of the redundant module. The two input ports of the redundant module are restored to power at the same time, and its output port can continuously output the DC voltage to power the load device.

[0029] In an optional embodiment, in a scenario where two power supplies are supplying power at the same time, if the second power supply loses power, the second power supply module cannot receive the AC voltage and cannot output the DC voltage to the redundant module. At this time, the first power supply still outputs the AC voltage to the first power supply module, and the first power supply module outputs the DC voltage to the input port 1 of the redundant module. In this scenario, the output port of the redundant module can still continuously output the DC voltage to power the load device. If the second power supply resumes power supply, the second power supply module can receive the AC voltage and then output the DC voltage to the input port 2 of the redundant module. The two input ports of the redundant module resume power supply at the same time, and its output port can continuously output the DC voltage to power the load device.

[0030] By setting up a redundant module and two power modules, two power supplies can be supplied at the same time. When one power supply fails, the other power supply can still continue to supply power to ensure the normal operation of the load equipment.

[0031] The power switching module can control the connection or disconnection of the switch to realize active switching of the power supply mode. Optionally, in the scenario where the first power supply is powered alone, switch 1 and switch 3 are connected, switch 2 and switch 4 are disconnected, and the first power supply module can receive AC voltage and then output DC voltage to the input port 1 of the redundant module. If the power supply mode needs to be changed to the second power supply alone, the power switching module first controls switch 2 and switch 4 to be connected, and the second power supply module can receive AC voltage and then output DC voltage to the input port 2 of the redundant module. Afterwards, the power switching module controls switch 1 and switch 3 to be disconnected, and the first power supply module stops outputting DC voltage to the input port 1 of the redundant module. During the entire switching process, the redundant module has at least one power supply to ensure continuous output of DC voltage to power the load device.

[0032] Optionally, in a scenario where the second power supply is powered alone, switch 2 and switch 4 are connected, switch 1 and switch 3 are disconnected, and the second power supply module can receive AC voltage, and then output DC voltage to the input port 2 of the redundant module. If the power supply mode needs to be changed to power supply by the first power supply alone, the power switching module first controls switch 1 and switch 3 to be connected, and the second power supply module can receive AC voltage, and then output DC voltage to the input port 1 of the redundant module. Afterwards, the power switching module controls switch 2 and switch 4 to be disconnected, and the second power supply module stops outputting DC voltage to the input port 2 of the redundant module. During this switching process, the redundant module changes from being powered by the second power supply to being powered by two power supplies at the same time, and then changes to being powered by the first power supply. At least one input port of the redundant module has a DC voltage input, which can ensure the continuous output of DC voltage to power the load device.

[0033] In an optional embodiment, the above switches can be implemented by circuit breakers. Specifically, switch 1 is the first circuit breaker, switch 2 is the second circuit breaker, switch 3 is the third circuit breaker, and switch 4 is the fourth circuit breaker.

[0034] Through the above device, when any power supply fails, another power supply is guaranteed to continue to supply power, so that the controller can continue to work and reach the set working condition more quickly after the power supply switching is completed.
