[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0025] In order to solve the problem that the single power supply module in the prior art can no longer meet the needs of more current scenarios, the present application provides a multi-power supply module, such as Figure 1 As shown, the multi-power supply module includes a main power supply module and multiple secondary power supply modules;

[0026] The main power module is connected in parallel with multiple secondary power modules, the output end of the main power module and the output end of the secondary power module are connected to one end of the switch tube, and the other end of the switch tube is connected to the output end of the multi-power module; the feedback output end of the secondary power module is connected to the cathode of the diode, and the anode of the diode is connected to the output end of the multi-power module.

[0027] In an optional implementation of an embodiment of the present application, the multi-power supply module in the embodiment of the present application also includes a voltage-stabilizing source output module, a first output end of the voltage-stabilizing source output module is connected to a power feedback end of the main power supply module, a second output end of the voltage-stabilizing source output module is connected to an output end of the multi-power supply module, and an input end of the voltage-stabilizing source output module is connected to a voltage input end.

[0028] Furthermore, if Figure 2As shown, in the embodiment of the present application, the voltage-stabilizing source output module in the multi-power module is also connected to the switch tube and the voltage comparison circuit. The switch tube is used to turn on the switch tube so that the voltage-stabilizing source output module can supply power to the load when the main power module is abnormal. The power comparison circuit is used to compare the voltage supplied by the voltage-stabilizing source output module and the main power module to the load, and determine whether the main power module is abnormal through the difference between the two. That is, if the difference is large, it indicates that the main power module is abnormal.

[0029] The multi-power supply module in the embodiment of the present application can control the opening or closing of the secondary power supply module according to the increase or decrease of the load. If the current load increases, the secondary power supply module that is not turned on can be turned on (powered on) to meet the current load requirements. If the current load decreases, some of the secondary power supply modules can be turned off (powered off) accordingly to save resources. In addition, if a certain secondary power supply module fails or is abnormal, it can be replaced by other secondary power supply modules that are not turned on to ensure normal power supply to the load.

[0030] The following will combine the above Figure 1 and Figure 2 , the control method of the multi-power module in the embodiment of the present application is described in detail, such as Figure 3 As shown, the embodiment of the present application also provides a method for controlling multiple power modules, the steps of the method comprising:

[0031] Step 301, obtaining a first power-on timing sequence of multiple loads powered by multiple power modules, and determining a second power-on timing sequence according to the first power-on timing sequence, wherein the second power-on timing sequence represents a power-on timing sequence of a main power module and multiple secondary power modules;

[0032] In the embodiment of the present application, if there are multiple loads of the power supply module, the power-on of the multiple loads is sequential. For example, there are currently 5 loads, and each load is powered on at a certain interval. For example, each load is separated by 2s, then the power-on timing of the corresponding main power module and multiple secondary power modules can be based on the power-on timing of the multiple loads (every 2s), and the power-on timing of the corresponding main power module and multiple secondary power modules can also be corresponding, that is, every 2s. It should be noted that the first power-on in the multiple power modules is the main power module, and then the secondary power module. If a load currently requires two secondary power modules, then every 2s, there are two corresponding secondary power modules powered on until all loads are powered. It can be seen that in the embodiment of the present application, after power-on, for multiple loads, it is not necessary to turn on directly after the chip is powered on and reset. After ensuring that the load is initialized and reset, it enters work normally, and then gradually turns on the corresponding main and secondary power modules according to the different load opening sequence requirements to achieve the power-on timing of different loads. According to the different load opening sequence requirements, the power-on can be controlled to ensure that the load is turned on when the total power supply is stable, and the load is prevented from working abnormally or damaged when the total power supply is unstable.

[0033] Step 302, after the multiple power modules are powered on based on the second power-on sequence, obtaining a first current of the powered-on main power module and a second current of the powered-on secondary power module;

[0034] Step 303: adjusting the number of secondary power modules currently supplying power to the multiple loads according to the variation of the first current and / or the second current.

[0035] For the above steps 302 and 303, it is possible to determine whether the current load is increased or decreased based on the current changes of the main power supply module and the secondary power supply module that are currently powered on, so that the number of secondary power supply modules powered on can be adjusted. In a specific example, it can be that after 5 loads are currently powered on, if the current first current and the second current increase, it indicates that a new load is currently added, and it is necessary to power on the secondary power supply module that is not powered on to meet the power supply of the newly added load. If the current load is reduced from 5 to 3 loads, the first current and the second current are reduced, and the corresponding secondary power supply module that is powered on can be stopped to save resources, realize dynamic adjustment of the secondary power supply module, meet the real-time needs of the load, and improve the output efficiency. As for the determination value of the specific number of powered-on secondary power supply modules, it can be determined according to the change amount of the actual circuit.

[0036] It can be known from the above steps 301 to 303 that the multi-power module in the embodiment of the present application can not only determine the power-on sequence of each module in the multi-power module according to the power-on sequence of the load, so as to ensure that the load demand can be met when the total power supply is stable, and avoid the load from working abnormally or being damaged when the total power supply is unstable. In addition, after the load is powered on according to the power-on sequence, if the load increases or decreases, the corresponding first current and the second current will also increase or decrease accordingly, so that the number of power-on of the corresponding secondary power module can be adjusted. If the current increases, the number of power-on of the corresponding secondary power module can be increased for shunting. If the current decreases, the number of power-on of the corresponding secondary power module can be reduced to save resources. It can be seen that through the multi-power module in the embodiment of the present application, it is possible to adapt to multiple different situations of the load, meet the load demand and save resources at the same time, and solve the problem that the power supply of a single power module in the prior art can no longer meet the needs of more current scenarios.

[0037] In the embodiment of the present application, the method of adjusting the number of secondary power supply modules currently supplying power to multiple loads according to the change amount of the first current and / or the second current involved in step 303 in the embodiment of the present application may further include:

[0038] Step 11, after the first current and / or the second current increases, increasing the number of secondary power modules currently supplying power to the multiple loads;

[0039] Step 12: after the first current and / or the second current decreases, reduce the number of secondary power modules currently supplying power to the multiple loads.

[0040] In a specific example, step 11 and step 12 may be that if the current number of loads is 4, and currently 1 main power module and 3 secondary power modules are powered on to supply power to 4 loads, there are a total of 10 secondary power modules in the multi-power module. If 1 load requires 1 secondary power module to supply power, then if 3 new loads are calculated from the current change, then the 3 secondary power modules that are not powered on in the multi-power module need to be powered on to ensure the power supply demand of the loads. If 2 loads are reduced, then if 2 loads are reduced from the current change, then the 2 powered secondary power modules need to be powered off to save resources while ensuring the power supply demand.

[0041] It can be seen that in the embodiment of the present application, the system turns on or off a power module in real time according to different working states and the current detection conditions of each power module to ensure efficient output. For example, the load quantity of the system changes from full open to half of the original, and combined with the current detection value, some secondary power modules are turned off; the load of the system changes from half to full open, and combined with the current detection value, some secondary power modules are turned on; in the standby state, all secondary power modules are turned off, and only the main power module works. Turning on and off does not include the main power module.

[0042] In the embodiment of the present application, the method of increasing the number of secondary power modules after the current increases involved in the above step 11 can further include increasing the number of powered-on secondary power modules after the first current or the second current increases by a corresponding value, rather than increasing the number of powered-on secondary power modules only when the current increases, so as to avoid misoperation. Based on this, the method of increasing the number of secondary power modules currently supplying power to multiple loads after the first current and / or the second current increases involved in the above step 11 can further include:

[0043] Step 21 , when the first current exceeds a first preset threshold value, or the second current exceeds a second preset value, power on the unpowered secondary power supply module to perform current diversion.

[0044] It should be noted that the first current and the second current are both the currents of a single power module, that is, the second current refers to the current of a single secondary power module. The values ​​of the first preset threshold and the second preset threshold can be taken according to actual needs. It can be seen from the above step 21 that 1. If the current detection value of the main power module and the working secondary power module exceeds the set value, the non-working secondary power module is turned on for diversion to reduce the power supply pressure.

[0045] In addition, in the embodiment of the present application, if a certain primary power supply module continues to increase and its current is greatly different from that of other secondary power supply modules, it indicates that the current secondary power supply module is abnormal and needs to be stopped from continuing to supply power, while other secondary power supply modules are turned on to ensure normal power supply to the load. Therefore, the method of adjusting the number of secondary power supply modules currently supplying power to multiple loads according to the change amount of the first current and / or the second current involved in the above step 303 may further include:

[0046] Step 31, when it is detected that the power of any of the currently powered-on secondary power modules is higher than that of other secondary power modules, the secondary power module with higher power than other secondary power modules is turned off, and any unpowered secondary power module is powered on.

[0047] It can be seen that if the current detection values ​​of each power module are compared, if the current of a power module is larger, the power module is turned off and the power module that is not working is turned on to ensure the normal operation of the system.

[0048] In order to avoid abnormal power supply to the load due to abnormality or failure of the main power module, a voltage-stabilizing source output module is added in the embodiment of the present application to increase or replace the voltage. Therefore, the multi-power module in the embodiment of the present application also includes a voltage-stabilizing source output module. Based on this, the method steps in the embodiment of the present application may also include:

[0049] Step 41, when the secondary power module has a current anomaly, controlling the voltage stabilizing source output module to supply power to the main power module;

[0050] Step 42: When the main power module supplies power abnormally, the main power module is turned off, and the voltage stabilizing source output module is controlled to supply power to the load.

[0051] In this regard, combined with Figure 1 and Figure 2 It can be seen that the setting value of the output voltage Vout1 of the main module is greater than Vout, that is, Vout1-Vout=△V, and △V is set within the acceptable range of the system (for example, the voltage output to the load is 3.3V, the maximum input voltage of the chip is 3.6V, △V=0.3V); a diode is added to the feedback input end of the secondary power supply module, and the selected diode conduction voltage Von=△V is used to provide output capacity and avoid output voltage fluctuations of the secondary power supply module due to output parallel connection, thereby affecting the accurate and stable output of the secondary power supply module. The output voltages of other secondary power supply modules are Vout2=Vout3=,,,=Vout.

[0052] Since the outputs of the main power module and the secondary power module are connected in parallel, the main power module has a strong output capacity and is less affected by the load, while the output capacity of other power modules is small and is easily affected by the load, causing voltage fluctuations. A high-precision voltage regulator output voltage V is required to adjust the output of the main power module, thereby ensuring that the feedback of other power modules is not affected and ensuring accurate and stable output. Based on this, the voltage regulator output module in the embodiment of the present application is a high-precision voltage regulator output module, which is used for high-precision output and sampling devices; such as Figure 2 As shown, the high-precision voltage-stabilizing source output module powered by the same input voltage is connected to the feedback end of the main power module FB (voltage feedback), and the output voltage V=Vout1, ensuring that the FB feedback end of the main power module is not affected by the voltage fluctuation caused by the output parallel line. The voltage comparison circuit is used to compare the output voltage V of the high-precision voltage-stabilizing source with Vout1. According to the error value set by the system, when the Vout1 voltage deviates from the error value by a large margin, the power supply of the main power module is turned off, and the high-precision voltage-stabilizing source output module is used to temporarily supply power.

[0053] It can be seen that through the embodiments of the present application, power-on timing control of multi-module power supply, feedback coordination between the main output power module and the secondary output power module, and current sampling detection are implemented to achieve efficient output and ensure circuit safety, so that the multi-power supply module can meet the load requirements well.

[0054] Corresponding to the above Figure 3 The present application embodiment also provides a control module, such as Figure 4 As shown, the device comprises:

[0055] The processing module 402 is used to obtain a first power-on timing sequence of multiple loads powered by multiple power modules, and determine a second power-on timing sequence according to the first power-on timing sequence, wherein the second power-on timing sequence represents a power-on timing sequence of a main power module and multiple secondary power modules;

[0056] An acquisition module 404, configured to acquire a first current of a powered-on main power module and a second current of a powered-on secondary power module after the multiple power modules are powered-on based on a second power-on sequence;

[0057] The first control module 406 is used to adjust the number of secondary power modules currently supplying power to the multiple loads according to the change in the first current and / or the second current.

[0058] Through the control of the control module in the embodiment of the present application, the multi-power supply module can not only determine the power-on sequence of each module in the multi-power supply module according to the power-on sequence of the load, so as to ensure that the load demand can be met when the total power supply is stable, and avoid the load from working abnormally or being damaged when the total power supply is unstable. In addition, after the load is powered on according to the power-on sequence, if the load increases or decreases, the corresponding first current and the second current will also increase or decrease accordingly, so that the power-on number of the corresponding secondary power supply module can be adjusted. If the current increases, the power-on number of the corresponding secondary power supply module can be increased for shunting. If the current decreases, the power-on number of the corresponding secondary power supply module can be reduced to save resources. It can be seen that through the multi-power supply module in the embodiment of the present application, it is possible to adapt to multiple different load situations, meet the load demand, and save resources at the same time, solving the problem that the power supply of a single power supply module in the prior art can no longer meet the needs of more current scenarios.

[0060] In an optional implementation manner of an embodiment of the present application, the first control unit in the embodiment of the present application may further include: a first control subunit, used to power on an unpowered secondary power supply module for current diversion when the first current exceeds a first preset threshold value or the second current exceeds a second preset value.

[0061] In an optional implementation of an embodiment of the present application, the first control module in the embodiment of the present application may further include: a third control unit, which is used to shut down the secondary power supply module that is higher than the power supply of other secondary power supply modules and power on any secondary power supply module that is not powered on, if it is detected that the power supply of any secondary power supply module that is currently powered on is higher than that of other secondary power supply modules.

[0062] In an optional implementation of the embodiment of the present application, the multi-power supply module in the embodiment of the present application also includes a voltage-stabilizing source output module. Based on this, the device in the embodiment of the present application may also include: a second control module, which is used to control the voltage-stabilizing source output module to supply power to the main power supply module when a current abnormality occurs in the secondary power supply module; a third control module, which is used to shut down the main power supply module and control the voltage-stabilizing source output module to supply power to the load when a power supply abnormality occurs in the main power supply module.
