For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of a power supply system of the present invention, includes: an ac input module 110 for connecting an ac input; a dc output module 120 connected to the ac input module 110 for providing a dc output; a main control module 140, a standby control module 150 and a switching module 130; the switching module 130 is connected to the main control module 140, the standby control module 150 and the dc output module 120, and is configured to switch the conduction between the main control module 140 or the standby control module 150 and the dc output module 120 to control the output of the dc output module 120; the main control module 140 is connected to the standby control module 150, and configured to output a first control level to the standby control module 150 to start the standby control module 150 when the main control module 140 finishes downloading the software package to be upgraded, and output a second control level to the switching module 130, so as to switch the standby control module 150 to be connected to the switching module 130; the main control module 140 starts to upgrade after the standby control module 150 is conducted with the switching module 130, and outputs a third control level to the switching module 130 after the upgrade is completed, so as to switch the main control module 140 to be conducted with the switching module 130. Specifically, the ac input end of the power system is used to connect to an ac power grid to receive ac input and perform ac processing, the dc output module 120 is used to connect to the ac input module 110, and the dc output module 120 is obtained by processing the output of the ac input module 110, wherein the processing process of the dc output module 120 is controlled by the main control module 140, so that the output end of the dc output module 120 obtains the required dc output. In the upgrading process, the main control module 140 first downloads the corresponding software package to be upgraded, and outputs the corresponding first control level to the standby control module 150 after the downloading is completed, so as to trigger the standby control module 150 to start. In addition, the main control module 140 outputs a second control level to the switching module 130, and the switching standby control module 150 is conducted with the switching module 130. After the standby control module 150 is conducted with the switching module 130, the standby control module 150 controls the dc output module 120 to operate to control the output of the dc output module 120. At this time, the main control module 140 starts to load the software package for upgrading, and the main control module 140 resets and restarts when the software package is loaded and run in the upgrading process. After the main control module 140 finishes upgrading, it outputs a third control level to control the switching module 130 to switch, so that the main control module 140 is conducted with the switching module 130, and at this time, the whole power system is restored to a normal working state in which the upgraded main control module 140 controls the dc output module 120 to work. The whole power supply system is upgraded, power failure or power failure can not occur in the upgrading process, and the reliability of the power supply system is improved.
In an embodiment, after outputting the third control level, the main control module 140 outputs a fourth control level to the standby control module 150 to turn off the standby control module 150. Specifically, after the main control module 140 finishes upgrading and enters a normal working state, it may output a control level through the main control module 140 to turn off the standby control module 150, i.e., the standby control module 150 is restored to a sleep state.
In an embodiment, the standby control module 150 outputs a fifth control level to the main control module 140 after starting up; the main control module 140 outputs the second control level to the switching module 130 when receiving the fifth control level; specifically, after the standby control module 150 receives the control level of the main control module 140 and starts to operate, it needs to initialize the standby control module 150 to make it enter an operating state, and after the standby control module 150 completes initialization, it can normally control the dc output module 120, at this time, it replies a feedback signal to the main control module 140, i.e., outputs the fifth control level to the main control module 140, and the main control module 140 receives the feedback signal and then outputs the control level to control the switching module 130 to switch the standby control module 150 to be conducted with the switching module 130. So as to ensure that the standby control module 150 and the switching module 130 can control the dc output module 120 uninterruptedly after being conducted.
In an embodiment, the main control module 140 outputs the second control level after a preset time interval after outputting the first control level. Specifically, after the standby control module 150 receives the control level of the main control module 140 and starts to operate, it needs to initialize the standby control module 150 to make it enter an operating state, and after the standby control module 150 completes initialization, it can normally control the dc output module 120. Due to the time required for the initialization of the standby control module 150, a preset time period can be set according to the time required for the initialization of the standby control device, and the preset time period is greater than or equal to the time required for the initialization of the standby control module 150. After the main control module 140 outputs the first control level to control the standby control module 150 to start, it waits for the preset time period to output the second control level to switch the standby control module 150 to be conducted with the switching module 130. So as to ensure that the standby control module 150 and the switching module 130 can control the dc output module 120 uninterruptedly after being conducted.
In an embodiment, the main control module 140 detects a working state thereof after the upgrade is completed, and outputs the third control level to the switching module 130 when the working state is normal. Specifically, the main control module 140 performs self-checking after upgrading is completed to determine whether the upgraded state of the main control module 140 is normal, and when the state of the main control module 140 is normal, the main control module 140 and the switching module 130 are switched to be in conduction by outputting a control level. The detection of the state of the main control module 140 ensures that when the main control module 140 is switched to control the dc output module 120, the abnormal control of the upgraded main control module 140 on the dc output module 120, which results in the abnormal output of the power supply system, does not occur after the switching is performed due to the abnormal state of the main control module 140. The uninterrupted power output is realized.

Specifically, when the main control module 140 controls the switching standby control module 150 to control the dc output module 120, it may detect the output of the dc output module 120 through the main control module 140, and when the output of the dc output module 120 is normal, the upgrade action corresponding to the main control module 140 is started.

Specifically, on the above basis, when the main control module 140 detects that the output of the dc output module 120 is abnormal, it indicates that the standby control module 150 may have an abnormality, and at this time, the standby control module 150 is switched to control the dc output module 120, which may cause the abnormality of the power output.

In the upgrading process, the main control module 140 first downloads the corresponding software package to be upgraded, and controls the standby control module 150 to start after the downloading is completed. In addition, the main control module 140 controls the switching module 130 to switch, so that the standby control module 150 is conducted with the switching module 130. After the standby control module 150 is conducted with the switching module 130, the standby control module 150 controls the dc output module 120 to operate to control the output of the dc output module 120.
