Background
At present, for devices with large power consumption, such as a Network Video Recorder (NVR) or a server, a multi-power supply mode is generally required to be adopted for power supply, for example, a power supply mode of an N +1 redundant power supply is adopted for power supply, that is, N +1 power supply modules are used for power supply for the devices.
In the related art, when a power supply mode with multiple power supplies is adopted to supply power to equipment, and power modules are sequentially connected into the equipment, the problem that the load power consumption of the power modules is greater than the output power consumption of the power modules easily occurs. When the load power consumption of the power module is greater than the output power consumption of the power module, the power module enters an OCP (Over current protection) protection mode. The load power consumption of the power supply module is the power consumption of the equipment powered by the power supply module. For example: under the condition that the equipment is only connected with one power supply module and is not connected with a second power supply module, the power consumption of the equipment is larger than the output power consumption of the connected power supply module, and at the moment, the connected power supply module enters an OCP protection mode.
After the power module enters the OCP protection mode, even if subsequent other power modules are all connected to the device and the output power consumption of all the connected power modules reaches the power consumption of the electronic device, the power module cannot exit the OCP protection mode, that is, the power module cannot supply power to the device, which may affect the performance of the device to a certain extent.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The embodiment of the invention provides electronic equipment and a power supply control method and device thereof, which are used for avoiding the situation that when the electronic equipment is powered by adopting a multi-power supply mode, a power module enters an OCP (optical communications protocol) protection mode to influence the performance of the electronic equipment.
As shown in fig. 1, which is a schematic structural diagram of an electronic device according to an embodiment of the present invention, the electronic device 100 is provided with a power supply control circuit 110, which includes a power supply controller 111;
the power supply controller 111 is configured to detect the number of power modules that have been connected to the electronic device, as a first number, and determine whether the first number is not less than a preset number threshold; if the first quantity is not less than the preset quantity threshold value, sending a power supply control signal to the power module 200;
the power module 200 is configured to supply power to the electronic device 100 after receiving the power supply control signal.
In one implementation, the electronic device may be any type of device, and the electronic device may be connected to multiple power supply modules to supply power through the connected multiple power supply modules. For example, the electronic device may be a device with a large power consumption, such as a Network Video Recorder (NVR) or a server, where the large number may refer to a number of paths exceeding a preset value.
In this embodiment of the present invention, the electronic device 100 may be provided with a power supply control circuit 110, where the power supply control circuit 110 may include a power supply controller 111, and the power supply control circuit 110 is configured to control a timing when a plurality of power modules connected to the electronic device start to supply power to the electronic device. In one case, the power supply controller may be a single chip microcomputer and a Complex Programmable Logic Device (CPLD) or other controllers.
After the power supply controller 111 is powered on, the number of power modules 200 that have been connected to the electronic device 100 may be detected in real time or at regular time as a first number, and then, whether the first number is not less than a preset number threshold is determined; if the first number is not less than the preset number threshold, the power supply controller 111 sends a power supply control signal to the power module 200, that is, the power module 200 of the electronic device is connected. After receiving the power supply control signal, the power supply module 200 supplies power to the electronic device 100. Wherein, the power module 200 may be configured to supply power to the electronic device: the electronic device 100 is powered on as a whole, that is, the electronic device 100 is powered on to start and operate various functional devices.
The preset number threshold is set for the staff according to the power consumption of the electronic device 100 in advance, and it can be ensured that at least the power modules with the preset number threshold supply power to the electronic device 100, so that the situation that the power modules enter the OCP protection mode can be avoided.
In view of this, after receiving the power supply control signal, the first number of power modules 200 connected to the electronic device 100 may simultaneously supply power to the electronic device 100, so as to avoid the power modules entering the OCP protection mode.
In one implementation, each power module may include two types of power supplies, for example, may include a first power supply and a second power supply, the first power supply being: the power supply which can output current by being connected with the electronic equipment and being plugged in the power line is characterized in that the first power supply can directly supply power for the electronic equipment after being connected with the electronic equipment and being plugged in the power line. The second power supply may be: the power supply is connected with the electronic equipment and is plugged in the power line, and the power supply can output current after receiving the power supply control signal, namely, the second power supply is connected with the electronic equipment and is plugged in the power line, and supplies power for the electronic equipment after receiving the power supply control signal. The power module can be connected with alternating current through a power line, and can convert the connected alternating current into direct current to supply power to the electronic equipment. In one case, the Power module may be a crps (common Redundant Power supplies) Power module, a first Power source of the Power module may convert the accessed ac Power into a voltage of +12V _ SB to supply Power to the electronic device, and a second Power source of the Power module may convert the accessed ac Power into a voltage of +12V to supply Power to the electronic device.
In one implementation, after the power module 200 is plugged into the electronic device 100, the first power source may be used to supply power to the power supply controller 111, and after the power supply controller 111 supplies power, the power supply control process provided by the embodiment of the present invention is started. Wherein, the power module 200 is plugged into a power line, i.e. ac power is connected through the power line.
In one case, the preset number threshold may be less than the number of power modules required to be connected by the electronic device 100. For example: the number of power modules that need to be connected to the electronic device is 5, and the preset number threshold may be 2, that is, when the power supply controller 111 determines that the number of power modules connected to the electronic device 100 is greater than or equal to 2, the power supply controller may send a power supply control signal to the power module 200 connected to the electronic device 100. In one case, when the power supply controller 111 determines that the number of power modules connected to the electronic device 100 is equal to 2, the power supply controller sends a power supply control signal to the power modules 200 connected to the electronic device 100, and at this time, after the two power modules 200 connected to the electronic device 100 receive the power supply control signal, the electronic device 100 is powered. Subsequently, a power module 200 is connected to the electronic device 100, and at this time, the connected power module 200 receives the power supply control signal after being connected, so as to supply power to the electronic device 100.
In the embodiment of the invention, the electronic device can detect the first number of the power modules connected to the electronic device through the power supply controller in the power supply control circuit, and when the first number is judged to be not less than the preset number threshold, the electronic device sends the power supply control signal to the power modules, so that the power modules supply power to the electronic device. The power module is prevented from being insufficient in output power consumption to support the power consumption of the electronic equipment, so that the power module enters an OCP protection mode and the performance of the electronic equipment is prevented from being affected.
In one implementation, as shown in fig. 2, the power supply control circuit 110 may further include a dc chopper 112; each power module 200 may include a first power supply 210;
the first power source 210 of the power supply module 200 is electrically connected to the power supply controller 110 through the dc chopper 112;
the dc chopper 112 is configured to convert a first voltage output by the first power supply 210 of the power supply module 200 into a second voltage, and supply power to the power supply controller 111.
In one case, the first voltage output by the first power supply 210 of the power module 200 may not meet the voltage required for the power controller 111 to operate. In view of this, the power supply control circuit 110 may also include a direct current chopper DC/DC. The first power source 210 of the power supply module 200 is electrically connected to the power supply controller 110 through the dc chopper 112. The first voltage output by the first power source 210 of the power module 200 is converted into the second voltage after passing through the dc chopper 112, so as to supply power to the power supply controller 111. As shown in fig. 3, the first voltage output from the first power source of the power module 200 is +12V _ SB, and is converted into the second voltage of +3.3V _ SB by the dc chopper 112.
The dc chopper 112 may be any type of dc chopper, and the embodiment of the present invention is not limited to the type of the dc chopper 112.
In one implementation, as shown in fig. 2, each power module 200 may further include a second power supply 220;
the power module 200 is configured to turn on the second power supply 220 after receiving the power supply control signal, and supply power to the electronic device 100 by using the second power supply 220.
It is understood that the second power source of the power module 200 is a power source that is connected to the electronic device 100 and plugged into a power line, and supplies power to the electronic device 100 only after receiving the power supply control signal. Before the second power of the power module 200 receives the power supply control signal, after the power module 200 is connected to the electronic device 100 and the power line is plugged in, the second power may be in an off state until the second power is turned on after the power supply control signal is received, and the power module 200 uses the second power 220 to supply power to the electronic device 100.
In one implementation, in order to prevent the reverse flow of the current of the power supply modules 200, as shown in fig. 4, the power supply control circuit 110 may further include a plurality of diodes 113, and the first power supply 210 of each power supply module 200 is electrically connected to the dc chopper 112 through a diode 113.
It is understood that the maximum power consumption of the electronic device 100 is determined, and the number of power modules 200 required for the electronic device may also be determined. In this embodiment of the present invention, the number of the diodes 113 included in the power supply control circuit 110 may be the same as the number of the power modules 200 that the electronic device 100 needs to access, or the number of the diodes 113 included in the power supply control circuit 110 may be greater than the number of the power modules 200 that the electronic device 100 needs to access, which is all acceptable.
The diode 113 may be any type of diode, and the type of diode is not limited in the embodiments of the present invention.
Fig. 5 is a circuit diagram of the first power source 210 of the power module 200 connected to a diode 113. As shown in fig. 5, the first power supplies of the 5 power supply modules 200 that are connected are all power supplies with an output voltage of +12V _ SB, the voltages output by the first power supplies of the 5 power supply modules 200 are combined into a voltage of +12V _ SB through diodes, the diode shown in fig. 5 is a diode of type SK34, the "Dx" shown in fig. 5 can identify the diode, and the "+ 12V _ SBx" shown in fig. 5 can identify each power supply module 200, where x is 1, 2, 3, 4, and 5, and the "1" at two ends of the diode represents the cathode of the diode, and the "2" represents the anode of the diode.
In one implementation, as shown in fig. 6, the power supply control circuit 110 may further include a plurality of resistor sets, each resistor set includes a first resistor 114 and a second resistor 115, and each power module 200 corresponds to a different resistor set;
the first power supply 210 of each power supply module 200 is electrically connected to the power supply controller 111 through the first resistor 114 in a group of resistor groups, and is grounded through the first resistor 114 and the second resistor 115 in the group of resistor groups in sequence;
the power supply controller 111 is configured to detect the number of power modules 200 connected to the electronic device 100 by detecting the number of received third voltages, where each third voltage is: the first voltage output by the first power supply 210 of each power module 200 is divided by the first resistor 114 and the second resistor 115 in a resistor set.
In this implementation, the power supply control circuit 110 may further include a plurality of resistor sets, each resistor set includes a first resistor 114 and a second resistor 115, and each power module 200 corresponds to a different resistor set; the first resistor 114 and the second resistor 115 in each resistor group are configured to divide the output voltage of the first power supply 210 of the corresponding power module 200 to obtain a third voltage, and the power supply controller 111 is configured to detect the number of power modules 200 that have been connected to the electronic device 100 by detecting the number of the received third voltage.
The process of detecting, by the power supply controller 111, the number of the power modules 200 connected to the electronic device 100 by detecting the number of the received third voltages may be: the power supply controller 111 determines the detected number of the received third voltages as the number of the power supply modules 200 that have been connected to the electronic apparatus 100. For example: when it is detected that the number of the received third voltages is 0, it may be determined that the number of the power modules 200 connected to the electronic device 100 is 0; when it is detected that the number of the received third voltages is 1, it may be determined that the number of the power modules 200 connected to the electronic device 100 is 1; when it is detected that the number of the received third voltages is 2, it may be determined that the number of the power modules 200 connected to the electronic device 100 is 2, and so on.
The power module 200, the first resistor 114 and the second resistor 115 in the resistor group, and the power supply controller 111 are connected in the following manner: the first power supply 210 of each power supply module 200 is electrically connected to the power supply controller 111 through the first resistor 114 in a resistor group, and is grounded through the first resistor 114 and the second resistor 115 in the resistor group in sequence. Fig. 7 is a schematic diagram of a power module 200, a first resistor 114 and a second resistor 115 in a resistor group, and a connection circuit of a power supply controller 111. For example, when the first power supply 210 of the power module 200 can output a voltage of +12V _ SB and a third voltage of +3.3V _ SB is obtained by dividing the voltage by the first resistor 114 and the second resistor 115 in the resistor group, the resistance of the first resistor may be 12K ohms, and the resistance of the second resistor may be 4.7K ohms. It should be noted that the above is only an example, and the embodiment of the present invention does not limit the specific resistance values of the first resistor and the second resistor, and the embodiment of the present invention does not limit the voltage value of the first power source outputtable voltage, the voltage value of the second power source outputtable voltage, and the voltage value of the third voltage obtained by voltage division of the power module.
In one implementation, the power supply controller 111 may obtain the preset number threshold by reading a preset general purpose input/output GPIO state value.
In this implementation, the staff can set up general purpose input/output GPIO state values in advance according to the power consumption of the electronic device and the output power consumption of the power supply module, and the preset number threshold is represented by the set GPIO state values. Furthermore, in the power supply control process, after the power supply controller 111 determines the number, i.e. the first number, of the power modules 200 that have been connected to the electronic device 100, it may obtain the preset number threshold by reading the preset general purpose input/output GPIO state value, and execute the subsequent processes. Or, after the power supply controller 111 is powered, the preset general purpose input/output GPIO state value is read immediately to obtain the preset number threshold, and then the step of determining the number of the power modules 200 connected to the electronic device 100 is performed. For example, GPIO [ 1: 0], a state value of 00, which may characterize a preset number threshold of 2; GPIO [ 1: 0], a state value of 01, which may characterize a preset number threshold of 3. In the embodiment of the present invention, the Power Supply control signal is a Power Supply startup signal in a low level state, i.e., a PS _ ON signal (Power Supply ON).
Wherein the dashed lines in fig. 1, 2, 4 and 6 may indicate that they have not been connected.

s810: detecting the number of power supply modules accessed to the electronic equipment as a first number;

In one case, the power supply controller may be a single chip microcomputer and a CPLD (complex programmable Logic Device) or other controllers.
After the power supply controller is powered on, the number of power supply modules connected to the electronic equipment can be detected in real time or at regular time to serve as a first number, and then whether the first number is not smaller than a preset number threshold value or not is judged; if the first quantity is judged to be not less than the preset quantity threshold value, the power supply controller sends a power supply control signal to the power supply module, namely the power supply module of the accessed electronic equipment.
