[0041] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0042] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0043] The following is a detailed description of the solution of the present disclosure in conjunction with the specific drawings:

[0044] Figure 1 A schematic diagram of the structure of a DC power supply system provided by an embodiment of the present disclosure. Figure 1 , the DC power supply system comprises:

[0045] A first AC / DC module, a second AC / DC module, a first DC / DC module, a second DC / DC module, and a control module;

[0046] A first AC / DC module, wherein the input end is used to be connected to the mains, the first sub-end of the output end is connected to the first sub-end of the input end of the first DC / DC module, the second sub-end of the output end is connected to the second sub-end of the input end of the second DC / DC module, and the control end is connected to the first control end of the control module;

[0047] A second AC / DC module, wherein the input end is used to be connected to the mains, the first sub-end of the output end is connected to the first sub-end of the input end of the second DC / DC module, the second sub-end of the output end is connected to the second sub-end of the input end of the first DC / DC module, and the control end is connected to the second control end of the control module;

[0048] A first DC / DC module, a control terminal connected to a third control terminal of the control module, and an output terminal for connecting to an electrical appliance;

[0049] The second DC / DC module has a control end connected to the fourth control end of the control module, and an output end used to be connected to an electrical appliance.

[0050] The control module is configured to control the first AC / DC module, the second AC / DC module, the first DC / DC module, and the second DC / DC module to sleep in turn according to time.

[0051] The first AC / DC module is exactly the same as the second AC / DC module. The first AC / DC module is used to convert the AC power input from the mains into DC power, and output the converted DC power to the first DC / DC module or the second DC / DC module. The second AC / DC module is the same.

[0052] The first DC / DC module is exactly the same as the second DC / DC module. The first DC / DC module is used to step up or step down the DC voltage input by the first AC / DC module or the second AC / DC module, and output the output voltage to the electrical appliance. The second DC / DC module is the same.

[0053] The control module is used to control the working switch states of the first AC / DC module, the second AC / DC module, the first DC / DC module, and the second DC / DC module, and the control method is to adjust the switch states once every fixed time.

[0054] Specifically, the control module controls one of the first AC / DC module and the second AC / DC module to start working and the other to sleep at the same time; controls one of the first DC / DC module and the second DC / DC module to start working and the other to sleep. After a fixed time, the control module controls the working module to stop working and controls the sleeping module to start working. The control module changes the working state of the working module every fixed time.

[0055] For example, the control module controls the first AC / DC module to work at the first time, and the second AC / DC module starts to sleep. After a period of time, the control module controls the second AC / DC module to work and the first AC / DC module sleeps.

[0056] The control module controls the first AC / DC module, the second AC / DC module, the first DC / DC module, and the second DC / DC module to rotate, thereby avoiding the problem of shortening the life of the DC power supply panel due to long-term work, and extending the service life of the DC power supply panel.

[0057] In one embodiment, the DC power supply system further comprises:

[0058] A battery pack, a third DC / DC module, and a fourth DC / DC module;

[0059] A third DC / CD module, the input end of which is connected to the battery pack, the output end of which is used to be connected to the electrical appliance, and the control end of which is connected to the fifth control end of the control module;

[0060] The fourth DC / DC module has an input terminal connected to the battery pack, an output terminal used to be connected to an electrical appliance, and a control terminal connected to the sixth control terminal of the control module.

[0061] The control module is configured to adjust the third DC / DC module and the fourth DC / DC module to take turns according to time.

[0062] The battery pack is used to provide AC power to electrical appliances. The third DC / DC module is identical to the fourth DC / DC module, and the third DC / DC module and the fourth DC / DC module are used to step up or step down the AC voltage of the battery pack. The control module controls the third DC / DC module and the fourth DC / DC module to take turns to rest at a fixed time.

[0063] Specifically, the control module controls one of the third DC / DC module and the fourth DC / DC module to enter the working state, and controls the other to sleep. The working or sleeping state is changed every once in a while. The working DC / DC module steps up or down the output voltage of the battery pack, and outputs the stepped-up or stepped-down voltage to the electrical appliance.

[0064] For example, the control module controls the third AC / DC module to work at the first time, and the fourth AC / DC module starts to sleep. After a period of time, the control module controls the third AC / DC module to work and the fourth AC / DC module to sleep.

[0065] The control module controls the third DC / DC module and the fourth DC / DC module to take turns to rest, thereby avoiding the problem of shortening the life of the DC power supply panel due to long-term work and extending the service life of the DC power supply panel.

[0066] In one embodiment, the DC power supply system further comprises:

[0067] Supercapacitors;

[0068] The supercapacitor has an output end connected to an input end of a battery pack, and an input end connected to the mains.

[0069] Supercapacitors are used to charge the battery pack.

[0070] Specifically, after the battery pack runs out of power, the supercapacitor provides high-power power to the battery pack, so that the battery pack is fully charged in a short time, avoiding the battery pack stopping powering the electrical appliances due to insufficient power. When the supercapacitor runs out of power, the supercapacitor is powered by the mains.

[0071] The supercapacitor speeds up the charging of the battery pack and ensures the normal operation of the battery pack.

[0072] In one embodiment, the DC power supply system further comprises:

[0073] Detection module;

[0074] A detection module, wherein the first detection end is connected to the detection end of the first AC / DC module, the second detection end is connected to the detection end of the second AC / DC module, the third detection end is connected to the detection end of the first DC / DC module, the fourth detection end is connected to the detection end of the second DC / DC module, the fifth detection end is connected to the detection end of the third DC / DC module, the sixth detection end is connected to the detection end of the fourth DC / DC module, and the output end is connected to the input end of the control module.

[0075] The detection module is used to detect the operating status of the first AC / DC module, the second AC / DC module, the first DC / DC module, the second DC / DC module, the third DC / DC module and the fourth DC / DC module. If a fault is detected, the fault information is input to the control module. After receiving the fault information, the control module controls the fault module to enter a dormant state and controls the module that is exactly the same as the fault module to start running.

[0076] Taking the first AC / DC module as an example, if the detection module detects that the first AC / DC module is faulty, the detection module transmits the information that the first AC / DC module is faulty to the control module. The control module controls the first AC / DC module to enter a sleep state and controls the second AC / DC module to enter a working state according to the received detection information. Since the first AC / DC module is faulty, the control module no longer controls the first AC / DC module and the second AC / DC module to take turns to rest. Before the first AC / DC module is repaired normally, the second AC / DC module keeps working to ensure normal power consumption of electrical appliances.

[0077] The detection module can promptly detect whether there is a fault inside the DC panel, and adjust the sleep state of the internal modules of the DC panel according to the fault information to ensure the normal operation of the DC power panel.

[0078] In one embodiment, the DC power supply system further comprises:

[0079] Temperature sensor module;

[0080] The temperature sensing module has an output end connected to the seventh detection end of the detection module.

[0081] The temperature sensing module is used to detect the temperature information of the DC power supply panel. It usually contains one or more temperature sensors (such as thermistors, thermocouples, integrated circuit temperature sensors, etc.), which can sense the temperature changes of the surrounding environment or specific parts in real time and convert them into electrical signals.

[0082] Specifically, the temperature sensor detects the temperature information of the DC power supply screen and transmits the temperature information to the control module. The control module controls the rotation status of the first AC / DC module, the second AC / DC module, the first DC / DC module, the second DC / DC module, the third DC / DC module and the fourth DC / DC module in the DC power supply screen according to the temperature information detected by the temperature sensor.

[0083] If it is detected that the temperature of the DC power supply panel is too high, the control module controls all the working modules to enter the sleep state, and controls the modules in the sleep state to enter the working state. For example. If the first AC / DC module and the first DC / DC module are working at this time, and the second AC / DC module and the second DC / DC module are sleeping, if the temperature sensor detects that the temperature in the DC power supply panel is too high at this time, the information that the temperature in the detected DC power supply panel is too high is transmitted to the control module. After receiving the information that the temperature in the DC power supply panel is too high, the control module controls the working first AC / DC module and the first DC / DC module to enter the sleep state, and controls the second AC / DC module and the second DC / DC module to start working, and restarts the timing of the module rotation time.

[0084] The temperature sensor avoids the damage of the DC power supply screen due to over-high temperature and ensures the normal use of the DC power supply screen.

[0085] In one embodiment, the DC power supply system further comprises:

[0086] Warning module;

[0087] The alarm module has an input terminal connected to the seventh control terminal of the control module.

[0088] The alarm module is used to receive information from the control module and issue an alarm or remain silent according to the received information.

[0089] Specifically, the first AC / DC module, the second AC / DC module, the first DC / DC module, the second DC / DC module, the third DC / DC module and the fourth DC / DC module share an alarm module. The alarm module may include a sound alarm to prompt the staff that the DC power supply screen is faulty when a module fails.

[0090] For example, the detection module detects that the first AC / DC module has a fault, and transmits information about the fault of the first AC / DC module to the control module. After receiving the information about the fault of the first AC / DC module, the control module sends a first instruction to the alarm module. After receiving the first instruction, the alarm module can issue a sound alarm about "the first AC / DC module has a fault".

[0091] The control module can control the alarm module to emit an alarm sound according to the detection result of the detection module on the DC power supply screen, and the alarm module can emit different alarm sounds according to the information of the control module, so that the staff can find the source of the fault in time.

[0092] In one embodiment, the DC power supply system further comprises:

[0093] Indicator module;

[0094] The indication module has an input terminal connected to the eighth control terminal of the control module.

[0095] The indication module is used to indicate the module in working status.

[0096] The indication module includes a plurality of indication units. The first AC / DC module, the second AC / DC module, the first DC / DC module, the second DC / DC module, the third DC / DC module and the fourth DC / DC module each have a corresponding indication unit. The indication unit may include a red LED and a green LED to display the working status of the corresponding module. When the module is working normally, the corresponding indication module lights up green; when the module enters the dormant state, the corresponding indication module lights up yellow.

[0097] For example, when the control module is controlling the first AC / DC module to work, the control module controls the indicator module corresponding to the first AC / DC module to light up green. At this time, the control module is controlling the second AC / DC module to sleep, and the control module simultaneously controls the indicator module corresponding to the second AC / DC module to light up yellow.

[0098] The staff can understand the working status of the internal modules of the DC power supply panel by detecting the indicator light.

[0099] In one embodiment, the DC power supply system further comprises:

[0100] Communication module;

[0101] The communication module has an input terminal connected to the ninth control terminal of the control module.

[0102] The communication module serves as a bridge for data exchange between the DC power system and remote terminals (such as monitoring centers, mobile devices, etc.). It is responsible for receiving information from the control module and transmitting this information to the remote terminal through wireless or wired communication technology.

[0103] Specifically, the control module sends various information to the communication module, including information about the control module controlling other modules to take turns, information about the temperature sensor, and information about the fault detected by the detection module.

[0104] For example, the control module controls the operation of the first AC / DC module and sends the operation information of the first AC / DC module to the communication module. The staff learns the operation information of the first AC / DC module through the communication module.

[0105] The control module transmits fault information, temperature information, and rest information to the communication module. After receiving the message from the control module, the communication module transmits the message to the remote terminal. Through the information from the remote terminal, the staff can remotely understand the working status of the DC power supply panel and ensure the normal operation of the DC power supply panel.

[0106] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
