[0047] The core of the present invention is to provide a multi-functional socket and a power supply system. The multi-functional socket in the present invention not only has a conventional power supply mode (continuously supplying power to the load), but also can control the load to be powered on again in a fatigue test mode when the load is not in a running state after being powered on. Thus, in cooperation with the timed shutdown logic of the load after power-on, a large number of power-on-off cycles can be performed on the load to complete the AC fatigue test. Therefore, the AC fatigue test can be performed on the electrical equipment on the basis of carrying a commonly used socket, eliminating the need to carry a large-volume fatigue machine and reducing the test cost of the AC fatigue test.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a multifunctional socket provided by the present invention, the multifunctional socket comprises:

[0050] A power supply circuit connected to the control device;

[0051] A mode switching device connected to the control device, used for controlling the multi-function socket to be in a normal power supply mode or a fatigue test mode;

[0052] The control device is used to control the power supply circuit to continuously supply power to the load in the normal power supply mode; in the fatigue test mode, after the load is controlled by the power supply circuit to execute the re-power-on process, the load is controlled by the power supply circuit to execute the re-power-on process when the load is not in the running state, so as to cooperate with the timed shutdown logic of the load after power-on to realize the AC fatigue test of the load;

[0053] The load is a computer device.

[0054] Specifically, considering the technical problems in the above background technology, and considering (1) that the socket is a common power supply tool for computer equipment, it is light and low-cost, and (2) based on the timed shutdown logic of the load after power-on, the power-on control of the computer equipment by the socket can realize AC fatigue test. Therefore, in the embodiment of the present invention, with the cooperation of the "timed shutdown logic of the load after power-on", the multi-function socket "controls the execution of the re-power-on process when it detects that the load is not in the running state", so as to realize the AC fatigue test of the load. Therefore, the multi-function socket in the embodiment of the present invention supports the fatigue test mode. In the fatigue test mode, the control device in the embodiment of the present invention can first control the load to execute the re-power-on process through the power supply circuit, and then control the load to execute the re-power-on process through the power supply circuit when the load is not in the running state. That is, on the one hand, the load can be shut down at a scheduled time after power-on, and the multi-function socket can control the load to execute the re-power-on process when the load is not in the running state (including the shutdown state) in the fatigue test mode, that is, the load power-off-on cycle is realized, and the AC fatigue test can be carried out.

[0055] Among them, the timed shutdown logic after power-on means that the power can be shut down after the third preset time after power-on. The third preset time can be set independently, for example, it can be 2 minutes, etc., and the embodiment of the present invention is not limited here.

[0056] Specifically, the multi-function socket is essentially still a socket, and it also has the conventional power supply mode of an ordinary socket, that is, it can continuously supply power to the load through the power supply circuit.

[0057] Among them, in order to facilitate switching between the two working modes, a mode switching device is also provided in the embodiment of the present invention. Through the mode switching device, the multi-function socket can be conveniently and accurately operated in any working mode, making the AC fatigue test easier to carry out, which is beneficial to improving the test efficiency.

[0058] Specifically, the computer device may be of various types, such as a server, etc., which is not limited in the embodiment of the present invention.

[0059] In addition, considering that AC fatigue testing needs to be carried out under specified AC electrical parameters in some cases, in order to facilitate the execution of more diverse AC fatigue tests, the embodiments of the present invention may also include an electric energy conversion device and a parameter mode switching switch. The electric energy conversion device can adjust the preset electric energy parameters of the electric energy provided by the power supply circuit to the load under the control of the control device. Through the parameter mode switching switch, one of several preset parameter modes (any preset parameter mode includes target values ​​of several electric energy sub-parameters) can be conveniently selected as the target parameter mode. The control device can control the electric energy conversion device in the fatigue test mode so that the power supply circuit provides the load with "electric energy that meets the target parameter mode", thereby flexibly realizing customized AC fatigue testing.

[0060] Specifically, the parameter mode switching device may include a preset number of buttons, each button corresponds to a preset parameter mode, and when a button is pressed, it represents the selection of the preset parameter mode corresponding to the button as the target parameter mode, which has the advantages of easy operation, simple structure and low cost.

[0061] Among them, the structure of the electric energy conversion device can be of various types, and can be flexibly set according to the types of electric energy sub-parameters contained in the preset parameter mode. For example, when the types of electric energy sub-parameters include voltage and current, the electric energy conversion device can include a current regulation circuit and a voltage regulation circuit. The embodiments of the present invention are not limited here.

[0062] The present invention provides a multifunctional socket. Considering that (1) the socket is a common power supply tool for computer equipment and is light and low-cost, and (2) based on the timed shutdown logic of the load after power-on, AC fatigue test can be realized by controlling the power-on of the computer equipment through the socket, the multifunctional socket in the present invention not only has a conventional power supply mode (continuously powering the load), but also can control the load to be powered on again in the fatigue test mode when the load is not in the running state after power-on, so that a large number of power-on-off cycles can be performed on the load in cooperation with the timed shutdown logic of the load after power-on to complete the AC fatigue test, so that the computer equipment can be subjected to AC fatigue test on the basis of carrying a common socket, avoiding the need to carry a large-volume fatigue test machine, and also reducing the test cost of the AC fatigue test.

[0063] Based on the above embodiments:

[0064] As an optional embodiment, the control device includes:

[0065] An electrical parameter detection module connected to the output end of the power supply circuit, used to detect real-time electrical parameters of the power supply loop between the power supply circuit and the load;

[0066] The control module is used to control the power supply circuit to continuously supply power to the load in the normal power supply mode; in the fatigue test mode, after the load is controlled by the power supply circuit to execute the re-power-on process, the load is controlled by the power supply circuit to execute the re-power-on process when the load is not in the running state, so as to cooperate with the timed shutdown logic of the load after power-on to realize the AC fatigue test of the load;

[0067] When the load is not in operation, the process of controlling the load to re-power on through the power supply circuit includes:

[0068] If it is determined through the real-time electrical parameters that the load is not in operation, the load is controlled through the power supply circuit to execute the power-on process again.

[0069] Specifically, considering the real-time electrical parameters supplied to the load through the power supply circuit, it is possible to conveniently and accurately determine whether the load is in an operating state. Therefore, the control device in the embodiment of the present invention includes an electrical parameter detection mode and a control module. The control module can determine whether the load is in an operating state through real-time electrical parameters, thereby reducing the detection cost of the load operating state and improving the detection accuracy.

[0070] As an optional embodiment, the control module includes:

[0071] Timer;

[0072] The controller is used to control the power supply circuit to continuously supply power to the load in the normal power supply mode; in the fatigue test mode, after the load is controlled by the power supply circuit to execute the re-power-on process, the load is controlled by the power supply circuit to execute the re-power-on process when the load is not in the running state, so as to cooperate with the timed shutdown logic of the load after power-on to realize the AC fatigue test of the load;

[0073] The power-on process includes:

[0074] Under the timing of the timer, the power supply circuit is controlled to cut off power for a first preset time period, and the power supply circuit is controlled to supply power to the load for a second preset time period.

[0075] Specifically, considering that the power-off and power-on control of the load can be controlled by measuring the duration through a timer to ensure the completion of the load power-off and power-on actions, the control module in the embodiment of the present invention includes a timer and a controller. The controller can control the load to execute the re-power-on process through the power supply circuit in the fatigue test mode, and then control the load to execute the re-power-on process through the power supply circuit when the load is not in the operating state, so as to cooperate with the timed shutdown logic of the load after power-on to achieve AC fatigue testing of the load. The power-on process may include: under the timing of the timer, controlling the power supply circuit to cut off power for a first preset time, and controlling the power supply circuit to supply power to the load for a second preset time. On the one hand, the first preset power-off time can ensure that the load is completely powered off when entering the fatigue test mode. On the other hand, the second preset power supply time can ensure that the load has enough time to enter the power-on operating state, which is beneficial to improving the accuracy of the fatigue test.

[0076] Among them, the first preset time length and the second preset time length can be set independently. For example, the first preset time length can be 15 seconds, the second preset time length can be 5 minutes, etc., and the embodiment of the present invention does not limit this.

[0077] Specifically, in order to better illustrate the embodiments of the present invention, please refer to Figure 2 , Figure 2 A control flow chart of a fatigue test mode provided by the present invention, when the fatigue test mode is not entered, the power supply circuit can be controlled to continuously supply power to the load, after entering the fatigue test mode, the power supply circuit can be controlled to disconnect for a first preset time, and then the power supply circuit can be controlled to supply power to the load for a second preset time, and it can be determined whether the real-time current value is lower than a preset threshold value, if it is lower than the preset threshold value, it can return to execute the step of "controlling the power supply circuit to disconnect for the first preset time length", and when it is lower than the preset threshold value, it can be determined whether it is in a normal power supply mode, if it is in the normal power supply mode, the power supply circuit can be controlled to continuously supply power to the load, if it is not in the normal power supply mode, the action of "determining whether the real-time current value is lower than the preset threshold value" can be continuously and periodically executed.

[0078] The timer may be of various types, such as a timing chip, etc., which is not limited in the embodiment of the present invention.

[0079] Specifically, the controller may be of various types, such as a single chip microcomputer, etc., which is not limited in the embodiment of the present invention.

[0080] As an optional embodiment, the electrical parameter detection module includes a current sensor;

[0081] The electrical parameter detection module is specifically used to detect the real-time current value of the power supply loop between the power supply circuit and the load;

[0082] If the load is determined to be not in operation through the real-time electrical parameters, the power supply circuit controls the load to execute a power-on process including:

[0083] If the real-time current value is lower than the preset threshold value, it is determined that the load is not in operation, and the load is controlled by the power supply circuit to execute the power-on process again.

[0084] Specifically, considering that when the load is in an operating state, the current value output by the power supply circuit will reach a certain value, this feature can be used to accurately identify whether the load is in an operating state. Therefore, the electrical parameter detection module in the embodiment of the present invention includes a current sensor, which can determine that the load is not in an operating state when the real-time current value is lower than a preset threshold, thereby triggering "controlling the load to execute the power-on process through the power supply circuit".

[0085] The preset threshold value may be independently set, for example, 5 amperes, etc., and the embodiment of the present invention does not limit this.

[0086] As an optional embodiment, the multifunctional socket further includes a reminder connected to the controller;

[0087] The controller is also used to:

[0088] When the real-time current value is lower than the preset threshold, the number of power-on times with an initial value of zero is increased by one, and the control prompter prompts the latest number of power-on times. When entering the normal power supply mode, the number of power-on times is cleared to zero.

[0089] Specifically, considering that the number of power-on and power-off cycles of the load is an important parameter of the test during the AC fatigue test, the number of power-on and power-off cycles can be conveniently counted through the multi-function socket because it participates in the control process of the "load power-on and power-off cycles". Therefore, the controller in the embodiment of the present invention can increase the number of power-on cycles from zero to one when the real-time current value is lower than the preset threshold, and the control prompter can prompt the latest number of power-on cycles. It can also reset the number of power-on cycles to zero when entering the normal power supply mode, so as to facilitate re-counting when entering the fatigue test mode next time.

[0090] The prompter may be of various types, for example, an LED (Light-Emitting Diode) display, etc., which is not limited in the embodiment of the present invention.

[0091] In addition, it is worth mentioning that the embodiments of the present invention may also include a network communication module and a network terminal. The controller can communicate with the network terminal through the network communication module. In this case, the user can send a mode switching instruction to the controller through the network terminal to remotely control the working mode of the multi-function socket, and can also set a timed mode switching instruction through the network terminal, that is, a method of executing the mode switching instruction in advance, which further improves the convenience of mode switching.

[0096] The power output interface connected to the output end of the controllable switch is used to achieve electrical connection with the power plug of the load.

[0097] Specifically, the power supply circuit in the embodiment of the present invention includes a power input interface, a controllable switch and a power output interface. The AC power can be connected through the power input interface, and the on-off state of the controllable switch can control whether "the AC power is connected to the power output interface". The power output interface can be used to achieve electrical connection with the power plug of the load. The power supply circuit in the embodiment of the present invention has the advantages of simple structure and easy operation.

[0098] Specifically, it is worth mentioning that the power input interface in the embodiment of the present invention can be a plug for connecting to a wall socket so as to connect to the mains electricity from the wall socket, that is, the multi-function socket in the embodiment of the present invention is in the form of a portable socket strip.

[0099] The controllable switch may be of various types, such as a relay, etc., which is not limited in the embodiment of the present invention.

[0100] Of course, in addition to this specific form, the power supply circuit may also be of many other types, which is not limited in the embodiments of the present invention.

The mode switching switch is Figure 3 The control system is realized by a toggle switch with two modes, which has the characteristics of small size, low cost and easy operation.

[0102] Specifically, considering that there are a large number of AC fatigue test requirements for computer equipment in laboratory scenarios, the multi-function socket in the embodiment of the present invention can be designed in the form of a laboratory socket, that is, Figure 4 The socket shown in the side view is triangular, and this multifunctional laboratory socket can be placed snugly and stably on the test bench.

[0103] As an optional embodiment, the power output interface includes:

[0104] A two-hole socket jack connected to the output end of the controllable switch, used for connecting to the plug of the load through it;

[0105] A three-hole socket connected to the output end of the controllable switch, used for connecting to the plug of the load through it;

[0106] The two-hole socket and the three-hole socket are overlapped and arranged in the same area to prevent the two-hole socket and the three-hole socket from being plugged into at the same time.

[0107] Specifically, considering that there may be many types of power plugs for computer devices, in order to be suitable for loads of various types of power plugs, the power output interface in the embodiment of the present invention integrates two types of jacks, namely a two-hole socket jack and a three-hole socket jack, and in order to prevent plugs of two different types of jacks from being connected to the socket at the same time, the two-hole socket jack and the three-hole socket jack can be overlapped and arranged in the same area.

[0108] Multiple multifunctional sockets provided in the embodiments of the present invention may be integrated together as a multifunctional socket, thereby supporting simultaneous connection of multiple loads for power supply or AC fatigue testing.

[0116] Specifically, to better illustrate the embodiments of the present invention, please refer to Figure 5 , Figure 5 A control logic diagram of a display provided by the present invention.

[0117] Specifically, considering that when the value of the real-time electrical parameter is lower than the preset threshold, there is no need to display the real-time power of the load, and the operation of the display itself consumes power, the control module in the embodiment of the present invention can control the display to turn off when the value of the real-time electrical parameter is lower than the preset threshold, thereby saving energy.

[0118] The real-time electrical parameters may include real-time voltage values ​​and / or real-time current values.
