Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to ensure uninterrupted power supply of the power supply system, a redundant power supply scheme can be adopted, i.e. a plurality of power supply modules are arranged for the power supply system. In the prior art, standby function signal ends of a plurality of power modules are usually connected together so as to control the whole power supply system, but when one of the power modules fails and the standby function signal end outputs a high level, the high level is transmitted to the standby function signal ends of other power modules, so that the other power modules enter a standby state, the whole power supply system cannot normally supply power, and the power supply system can normally restore the power supply after the power module with the failure is removed from the power supply system.
In order to solve the above problem, the present application first proposes a power supply system, as shown in fig. 1, a power supply system 10 in this embodiment includes a control device 20, a main power module 120 and a standby power module 130, where the control device 20 includes a controller 110, the controller 110 is connected to the main power module 120 and the standby power module 130, and the controller 110 is configured to monitor turning on or off of a standby function of the main power module 120, obtain a working state of the main power module 120 when it is monitored that the standby function of the main power module 120 is turned on, and control turning on or off of the standby function of the standby power module 130 according to the working state of the main power module 120.
The Controller 110 in this embodiment may be a Micro Controller Unit (MCU), a Baseboard Management Controller (BMC), an Embedded Controller (EC), or the like.
When the controller 110 monitors that the standby function of the main power module 120 is turned on (the standby function may be turned on normally when the main power module 120 fails or operates within a range of a load setting parameter, etc.), the controller controls the standby function of the standby power module 130 to be turned on or off according to the operating state of the main power module 120. Specifically, the controller 110 determines whether the working state of the main power module 120 is an abnormal state, if so, it determines that the main power module 120 has a fault, and the controller 110 controls the standby function of the standby power module 130 to be turned off, so that the standby power module 130 is in a standby state, otherwise, it determines that the main power module 120 normally works, and the standby function of the standby power module 130 does not need to be started to supply power, and the controller 110 controls the standby function of the standby power module 130 to be turned off.
Different from the prior art, in the embodiment, when the standby function of the main power module is turned on, the controller controls the standby power of the standby power module to be turned on or turned off according to the working state of the main power module, so that the controller can control the standby function of the standby power module to be turned off when the standby function of the main power module is turned on due to the abnormal working of the main power module, so that the standby power module is in a power supply state to ensure the normal power supply of a power supply system; meanwhile, the controller can control the standby function of the standby power supply module to be started when the standby function of the main power supply module is started but works normally, so that the standby power supply module is in a standby state to reduce the power of the power supply system.
In another embodiment, as shown in fig. 2, the controller 110 of this embodiment includes a first signal input/output end 11, a second signal input/output end 12, a third signal input/output end 13 and a fourth signal input/output end 14, the main power module 120 includes a first standby signal end 21 and a first operating state signal end 22, the standby power module 130 includes a second standby signal end 31 and a second operating state signal end 32, the first signal input/output end 11 is connected to the first operating state signal end 22, the second signal input/output end 12 is connected to the first standby signal end 21, the third signal input/output end 13 is connected to the second standby signal end 31, and the fourth signal input/output end 14 is connected to the second operating state signal end 32.
The signal input/output terminal of the controller 110 is a General Purpose input/output (GPIO) port, and in other embodiments, the output signal terminal may also be an I2C or I2S type port. The first signal input/output end 11 and the second signal input/output end 12 of the controller 110 are in a signal receiving state to receive the working state signal and the standby signal from the first working state signal end 22 and the first standby signal end 21 of the main power module 120, respectively; the third signal input/output terminal 13 of the controller 110 is in a signal transmitting state to transmit the standby signal to the second standby signal terminal 31 of the standby power module 130, and the fourth signal input/output terminal 14 of the controller 110 is in a signal receiving state to receive the operating state signal from the second operating state signal terminal 32 of the standby power module 130.
Wherein, the standby signal and the working state information are both level signals; when the level of the first standby signal terminal 21 is low, the standby function of the main power module 120 is in an off state, the main power module 120 is in a power supply state, when the level of the first standby signal terminal 21 is high, the standby function of the main power module 120 is in an on state, and the main power module 120 is in a standby state; when the level of the first operating state signal terminal 22 is a high level, the main power module 120 is in a normal operating state, and when the level of the first operating state signal terminal 22 is a low level, the main power module 120 is in an abnormal operating state.
The functional terminals of the standby power module 130 are similar to the functional terminals of the main power module 120, and are not described in detail herein.
When the level received by the second signal input/output end 12 of the controller 110 from the first standby signal end 21 of the main power module 120 is switched from the low level to the high level, and the level received by the first signal input/output end 11 of the controller 110 from the first working state signal end 22 of the main power module 120 is the high level, it is considered that the standby function of the main power module 120 is turned on, and the main power module 120 works normally, the controller 110 controls the third signal input/output end 13 to output the high level to the second standby signal end 31 of the standby power module 130, so that the standby power module 130 is in the standby state, and the power consumption is reduced.
When the level received by the second signal input/output end 12 of the controller 110 from the first standby signal end 21 of the main power module 120 is switched from the low level to the high level, and the level received by the first signal input/output end 11 of the controller 110 from the first working state signal end 22 of the main power module 120 is the low level, it is considered that the standby function of the main power module 120 is turned on, and the main power module 120 works abnormally, the controller 110 controls the third signal input/output end 13 to output the low level to the second standby signal end 31 of the standby power module 130, so that the standby power module 130 is in a power supply state, and the normal power supply of the power supply system 10 is ensured.
Further, the main power module 120 further includes a first power management terminal 23, the standby power 130 includes a second power management terminal 33, the controller 110 further includes a third power management terminal 15 and a fourth power management terminal 16, the first power management terminal 23 is connected to the third power management terminal 15, and the second power management terminal 33 is connected to the fourth power management terminal 16.
The power management terminal is a power management bus PMBUS. In other embodiments, the power management terminal may also be a bus such as I2C or I2S, or other types of ports.
Alternatively, when the power supply system 10 is turned on, the third power management terminal 15 of the controller 110 provides a high level to the first power management terminal 23 of the main power module 120 to enable the main power module 120 to turn on the standby function, and the fourth power management terminal 16 of the controller 110 provides a high level to the second power management terminal 33 of the standby power module 130 to enable the standby power module 130 to turn on the standby function. That is, when the power supply system 10 is turned on, the standby functions of all the power modules are controlled to be turned on, so that the power consumption of the power supply system 10 can be further reduced.
Each power module in the power supply system 10 can be used as the main power module 120 or the backup power module 130 in different power supply scenarios, so when the power supply system 10 is started, configuration information should be set according to actual power supply requirements, and the controller 110 sets each power module as the main power module 120 or the backup power module 130 according to the configuration information.
Specifically, the controller 110 sets the first signal input/output end 11 and the second signal input/output end 12 as signal input ends according to the configuration information, so as to receive the standby signal of the main power module 120 from the first standby signal end 21 of the main power module 120 and receive the operating state signal of the main power module 120 from the first operating state signal end 22; meanwhile, the controller 110 sets the third signal input/output terminal 13 as a signal output terminal according to the configuration information to provide a standby signal to the second standby signal terminal 31 of the standby power module 130.
In other application scenarios, the controller 110 may further set the main power module 120 as a standby power module and the standby power module 130 as a main power module according to power supply requirements, specifically, may set the third signal input/output end 13 and the fourth signal input/output end 14 as signal input ends and the second signal input/output end 12 as signal output ends. The working principle is similar to the application scenario described above, and is not described here again.

The working principle of this embodiment is similar to that of the above embodiment, and is not described herein again.
Table 1 shows signal terminals of the main power module 120 and the standby power module 130 of this embodiment.
TABLE 1
In another embodiment, as shown in fig. 4, the control device 20 of the present embodiment further includes a switch module 140, the controller 110 further includes a fifth signal input/output end 17, the switch module 140 includes a first signal transmission end 41, a second signal transmission end 42 and a first control end 43, the first signal transmission end 41 is connected to the first standby signal end 21, the second signal transmission end 42 is connected to the second standby signal end 31, the fifth signal input/output end 17 is connected to the first control end 43, and the first signal transmission end 41 is selectively connected to or disconnected from the second signal transmission end 42.
Specifically, when the level received by the second signal input/output end 12 of the controller 110 from the first standby signal end 21 of the main power module 120 is changed from a low level to a high level, and the level received by the first signal input/output end 11 of the controller 110 from the first working state signal end 22 of the main power module 120 is a high level, it is determined that the standby function of the main power module 120 is turned on, and the main power module 120 works normally, the controller 110 controls the fifth signal input/output end 17 to output the first control signal to the first control end 43, the first control signal controls the first signal transmission end 41 of the switch module 140 to be communicated with the second signal transmission end 42, so that the first standby signal end 21 transmits a high level to the second standby signal end 31 to control the standby function of the standby power module 130 to be turned off, and the standby power module 130 is in a standby state to reduce power consumption.
When the level received by the second signal input/output end 12 of the controller 110 from the first standby signal end 21 of the main power module 120 is switched from the low level to the high level, and the level received by the first signal input/output end 11 of the controller 110 from the first working state signal end 22 of the main power module 120 is the low level, it is considered that the standby function of the main power module 120 is turned on, and the main power module 120 works abnormally, at this time, the controller 110 does not control the switch module 140, so that the first signal transmission end 41 and the second signal transmission end 42 of the switch module 140 keep the default off state, so that the second standby signal end 31 of the standby power module 130 receives the low level of the third input/output end 13 of the controller 110 by default, and the standby power module 130 is in the power supply state, so as to ensure that the power supply system 10 supplies power normally.
As can be seen from the above analysis, in order to reduce power consumption, when the power supply system 10 is powered on, the main power module 120 and the standby power module 130 are both in the standby state, so as to provide another embodiment, as shown in fig. 5, the switch module 140 of this embodiment further includes a second control terminal 44, the controller 110 further includes a sixth signal input/output terminal 18, the second control terminal 44 is connected to the sixth signal input/output terminal 18, when the level received by the second signal input/output terminal 12 of the controller 110 from the first standby signal terminal 21 of the main power module 120 is changed from the low level to the high level, and the level received by the first signal input/output terminal 11 of the controller 110 from the first operating state signal terminal 22 of the main power module 120 is the low level, the controller 110 controls the fifth signal input/output terminal 17 to output the second control terminal 43, the second control signal controls the first signal transmission terminal 41 to be disconnected from the second signal transmission terminal 42, and the controller 110 controls the sixth signal input/output terminal 18 to output a third control signal to the second control terminal 44 to control the second signal transmission terminal 42 to output a low level to the second standby signal terminal 31.
In another embodiment, as shown in fig. 6, the first signal transmission terminal I01, the second signal transmission terminal I02, the first control terminal CRT1 and the second control terminal CRT2 of the switch module 140 of this embodiment are respectively connected to the first standby function signal terminal SMART _ ON of the main power module 120, the second standby function signal terminal SMART _ ON of the standby power module 130, the fifth signal input/output terminal GPIO5 and the sixth signal input/output terminal GPIO6 of the controller 110. The working principle of which is not described in detail here.
Other arrangements and working principles of the embodiments of fig. 4 to 6 are similar to those of the embodiments of fig. 1 to 3, and are not described herein again.
It should be noted that, in order to improve the accuracy of the controller 110 in monitoring the operating state of the main power module 120, after the level of the first standby function signal terminal SMART _ ON of the main power module 120 is monitored to be switched from the low level to the high level, the level of the first operating state signal terminal PWR _ OK of the main power module 120 is monitored after a preset time interval, so as to avoid the problem that the level of the first operating state signal terminal PWR _ OK is not pulled down in a short time, which results in an erroneous monitoring result.
In other embodiments, the number of the power modules of the power supply system of the present application may also be more than two; and the controller can also select one or more power supply modules to supply power according to the load condition of the power supply system, for example, one power supply module supplies power when the load is light, and two or more power supply modules simultaneously supply power when the load is heavy.
The present application further provides a control device for redundant power supplies, which is the control device 110 in the power supply system 10, and is not described herein again.
The application further provides a control method of the redundant power supply, which can be used for the power supply system. As shown in fig. 7, fig. 7 is a schematic flowchart of an embodiment of a control method for a redundant power supply of the present application. The control method of the embodiment comprises the following steps:
step S701: the controller monitors the on and off of the standby function of the main power supply module.
The controller can receive a level signal of a standby signal end of the main power supply module through the input end and the output end to monitor the standby function of the main power supply module. For example, if the level received by the controller from the standby signal terminal of the main power module is high, it is considered that the standby function of the main power module is turned on, and if the level received from the standby signal terminal of the main power module is low, it is considered that the standby function of the main power module is turned off.
Step S702: the controller acquires the working state of the main power supply module when monitoring that the standby function of the main power supply module is started.
The controller can receive the level signal of the working state signal end of the main power supply module through the input end and the output end to monitor the working state of the main power supply module. For example, if the level received by the controller from the operating state signal terminal of the main power supply module is a high level, the main power supply module is considered to be operating normally, and if the level received from the operating state signal terminal of the main power supply module is a low level, the main power supply module is considered to be operating abnormally.
Step S703: and the controller controls the standby function of the standby power supply module to be turned on or off according to the working state.
Specifically, the present embodiment may implement step S703 by using the method shown in fig. 8. The method of the present embodiment includes steps S801 to S803.
Step S801: the controller determines whether the operating state is abnormal, if not, executes step S802, and if so, executes step S803.
Step S802: the controller controls the standby function of the standby power supply module to be started so as to enable the standby power supply module to be in a standby state.
In an application scenario, the controller may send a high level to the standby signal terminal of the standby power module through the input/output terminal to control the standby function of the standby power module to be turned on.
In another application scenario, the controller may control the switch module disposed between the standby signal end of the main power module and the standby signal end of the standby power module to be turned on, so that the main power module transmits a standby function start signal (i.e., a high level) to the standby power module through the switch module, and the standby power module is in a standby state.
Step S803: the controller controls the standby function of the standby power supply module to be turned off so that the standby power supply module is in a power supply state.
In an application scenario, the controller may send a low level to the standby signal terminal of the standby power module through the input/output terminal to control the standby function of the standby power module to be turned off.
In another application scenario, the controller may control the switch module disposed between the standby signal end of the main power module and the standby signal end of the standby power module to be turned off, and control the switch module to send a low level to the standby signal end of the standby power module to control the standby function of the standby power module to be turned off.
In another embodiment, as shown in fig. 9, the method of the present embodiment includes the steps of:
step S901: when the power supply system is started, the controller controls the standby function of the main power supply module to be started and controls the standby function of the standby power supply module to be started, so that the main power supply module and the standby power supply module enter a standby state.
The controller can send high level through the power management end of the main power module of the power management end and the power management end of the standby power module to control the standby function of the main power module to be started and the standby function of the standby power module to be started, and the power consumption of the power supply system can be further reduced.
Optionally, step S902 and step 903 may be further included after step S901.
Step S902: the controller obtains configuration information.
Step S903: and the controller controls the standby function of the main power supply module to be closed according to the configuration information.
When the power supply system works, only the main power module is used for supplying power to the equipment, so that after the power supply system determines the main power module according to the configuration information, the standby function of the main power module is controlled to be closed, and the main power module is in a power supply state.
Step S904: the controller monitors the on and off of the standby function and the working state of the main power supply module according to the configuration information.
Step S905: the controller acquires the working state of the main power supply module when monitoring that the standby function of the main power supply module is started.
Step S906: and the controller controls the standby function of the standby power supply module to be turned on or off according to the working state.
Steps S904-S906 are similar to steps S701-S703 described above and are not described in detail herein.
