If the specific posture (as shown in the drawings) changes, the directionality will also change accordingly.
[0021] As shown in Figure 1 The embodiments of the present application provide a power consumption test system 100, which comprises a connecting circuit 110, a current detection device 120, a controllable power supply 130 and a control device 140.
[0022] The connecting circuit 110 comprises an output end and at least two input ends. The output end of the connecting circuit 110 is connected to the current detection device 120, and the input ends of the connecting circuit 110 are respectively used for connecting at least two devices to be tested 200.
[0023] The controllable power supply 130 is used for connecting the devices to be tested 200 respectively to supply power to the devices to be tested 200. When the controllable power supply 130 is connected to one of the devices to be tested 200, the controllable power supply 130 supplies power to the device to be tested 200.
[0024] The control device 140 is in communication connection with the connecting circuit 110, the current detection device 120 and the controllable power supply 130. The control device 140 is used for controlling the controllable power supply 130 to supply power to the device to be tested 200 connected to one of the input ends, and controlling the connecting circuit 110 to transmit the power supply current of the device to be tested 200 which has been supplied with power through the output end to the current detection device 120. The control device 140 receives and stores the power supply current collected by the current detection device 120, and obtains the power consumption of the device to be tested 200 according to the power supply current.
[0025] In the power consumption test system 100, the at least two to-be-tested devices 200 are connected by the connection circuit 110 having at least two input terminals, the control device 140 controls the controllable power supply 130 to supply power to the to-be-tested device 200 connected to one input terminal, and controls the connection circuit 110 to transmit the power supply current of the to-be-tested device 200 that has been supplied with power to the current detection device 120 through the output terminal, and then the control device 140 receives and stores the power supply current collected by the current detection device 120, and obtains the power consumption of the to-be-tested device 200 according to the power supply current. Thus, the power consumption of the to-be-tested device 200 is automatically tested, thereby saving manpower and time for power consumption test, and improving test efficiency.
[0026] As shown in Figure 2 In some embodiments, the connection circuit 110 can include a multiplexer 111, and the multiplexer 111 is configured to time-divisionally connect the plurality of input terminals with the output terminal. It can be understood that the control device 140 can send a control instruction to the multiplexer 111, and the multiplexer 111 controls the corresponding channel to be turned on according to the control instruction, so that the corresponding input terminal is connected with the output terminal. Of course, in the present embodiment, the connection circuit 110 is not limited to the multiplexer 111, and can also be other circuit structures, for example, a plurality of controllable switches are respectively connected between the to-be-tested devices 200 and the current detection device 120, and the control device 140 turns on the controllable switch connected to the to-be-tested device 200 that needs to be tested, so as to realize the power consumption test of the to-be-tested device 200.
[0027] Further, the control device 140 is configured to control the multiplexer 111 to time-divisionally connect the plurality of input terminals with the output terminal, so as to respectively make the to-be-tested devices 200 perform power consumption test on the corresponding to-be-tested devices 200.
[0028] Thus, by sending a control instruction to the multiplexer 111 through the control device 140, the multiplexer 111 can time-divisionally control the turn-on of different channels, so as to conveniently realize the power consumption test of different to-be-tested devices 200, and can also simplify the connection structure of the control device 140 and the connection circuit 110, thereby reducing the cost.
[0029] In the present embodiment, the current detection device 120 can be a precision ammeter, the controllable power supply 130 can be a programmable power supply, and the control device 140 can be a computer terminal.
[0030] In some embodiments, when the controllable power supply 130 supplies power to the to-be-tested device 200, the to-be-tested device 200 is started to perform power consumption test on the to-be-tested device 200.
[0031] In some embodiments, the to-be-tested device 200 is started to perform power consumption test on the to-be-tested device 200 when the controllable power supply 130 supplies power to the to-be-tested device 200. Figure 3As shown, a power supply circuit 150 can be arranged between the controllable power supply 130 and each of the devices under test 200, and the controllable power supply 130 controls the power supply circuit 150 to supply power to the corresponding device under test 200 according to the control signal sent by the control device 140, while the multiplexer 111 connects the corresponding input terminal and output terminal to enable the current detection device 120 to detect the power supply current of the corresponding device under test 200.
[0032] In some embodiments, the control device 140 is further configured to receive the power supply voltage provided by the controllable power supply 130 to the device under test 200, so as to obtain the power consumption of the device under test 200 according to the power supply voltage and the power supply current.
[0033] It can be understood that the power consumption of the device under test 200 needs to be determined according to the power supply current and the power supply voltage, and therefore the control device 140 further receives the power supply voltage provided to the device under test 200 to obtain the power consumption.
[0034] In some embodiments, the control device 140 is further configured to control the controllable power supply 130 to provide different power supply voltages to the device under test 200, and receive and store the power supply current detected by the current detection device 120 under each power supply voltage.
[0035] The device under test 200 can have different modes, and the power consumption of the device under test 200 is different in different modes, and the power supply voltage of the device under test 200 is also different in different working modes. Therefore, the control device 140 controls the controllable power supply 130 to provide different power supply voltages to the device under test 200, and the current detection device 120 collects the power supply current of the device under test 200 in different modes and sends it to the control device 140, so that the control device 140 can receive and store the power supply voltage and the power supply current of the device under test 200 in different modes to obtain the power consumption of the device under test 200 in different modes.
[0036] In some embodiments, the control device 140 can issue control instructions to the controllable power supply 130 and the device under test 200 according to the mode of the device under test 200 to be tested, so that the controllable power supply 130 provides the required power supply voltage to the device under test 200, and the device under test 200 works in the mode to be tested. For example, the device under test 200 can include a working mode, an idle mode, a sleep mode, a power-off mode, etc. The working mode can include a high-power mode, a low-power mode, a normal-power mode, etc. The control device 140 or the controllable power supply 130 can store the required power supply voltage of the device under test 200 in different modes, so that when testing the power consumption of the device under test 200 in different modes, the controllable power supply 130 provides the corresponding power supply voltage to the device under test 200, and the power consumption of the device under test 200 in different scenarios is tested.
[0037] In some embodiments, the control device 140 is further configured to generate and display a relationship chart of the to-be-tested device 200 according to the power supply voltage and the power supply current.
[0038] The control device 140 can facilitate the tester to view the power consumption test of the to-be-tested device 200 by generating the relationship chart according to the power supply voltage and the power supply current, and help the tester to determine whether the power consumption of the to-be-tested device 200 meets the requirements.
[0039] In some embodiments, as shown in FIG. 2, the to-be-tested device 200 is a storage device, the to-be-tested device 200 includes a main controller 210 and a memory 220, the power supply voltage includes a first power supply voltage of the main controller 210 and a second power supply voltage of the memory 220, and the power supply current includes a first power supply current of the main controller 210 and a second power supply current of the memory 220. Figure 4
[0040] The main controller 210 and the memory 220 in the storage device need to be powered respectively, so the controllable power supply 130 needs to power the main controller 210 and the memory 220 respectively. It can be understood that the power supply circuit 150 can convert the power supply voltage provided by the controllable power supply 130 into two power supply voltages, i.e., the first power supply voltage and the second power supply voltage, to power the main controller 210 and the memory 220 respectively. In this way, the controllable power supply 130 can provide the first power supply voltage for the main controller 210 and the second power supply voltage for the memory 220 through the power supply circuit 150.
[0041] In some embodiments, the storage device is an EMMC (Embedded Multi Media Card) memory or a UFS (Universal Flash Storage) memory. At this time, the first power supply voltage is the voltage of the VCC terminal of the EMMC memory and the UFS memory, and the second power supply voltage is the voltage of the VCCQ terminal of the EMMC memory and the UFS memory.
[0042] Of course, in the embodiments of the present application, the to-be-tested device 200 is not limited to the storage device, but can also be other electronic components that need to be tested for power consumption, such as some power devices, Bluetooth chips, communication chips, etc.
[0043] In some embodiments, the control device 140 is in communication connection with the connection circuit 110, the current detection device 120, and the controllable power supply 130 through Ethernet cables respectively.
[0044] Those skilled in the art should understand that the above embodiments are only used to illustrate the present application, but not as a limitation to the present application, and any appropriate changes and variations made to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
