[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in combination with specific embodiments of the present invention and the corresponding drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] According to an embodiment of the present invention, a socket system is provided. Refer to Figure 1 Schematic structural diagram of an embodiment of the device of the present invention as shown. The socket system may include: a plug and a socket. The plug and the socket are matched and arranged.

[0042] Wherein, the plug has plug pins and metal false feet. Both the plug pins and the metal false feet are arranged on the body of the plug. The metal false feet are false pins independently arranged from the plug pins.

[0043] The socket has socket power supply jacks and metal false-foot sockets. Both the socket power supply jacks and the metal false-foot sockets are arranged on the body of the socket. The metal false feet can be inserted into the metal false-foot sockets. The metal false-foot sockets are false socket jacks independently arranged from the socket power supply jacks.

[0044] Matched with the body of the socket, a jack control unit is further provided. The jack control unit is respectively connected to the power supply jack of the socket and the metal false foot jack, and is configured to control the plug to be connected to the power supply through the socket, that is, to make the power supply jack of the socket powered on, only when the plug pin is inserted into the power supply jack of the socket, the metal false foot is inserted into the metal false foot jack, and the parameters of the metal false foot jack meet the set conditions.

[0045] In related solutions, electrical sockets usually use insulating parts inserted into the sockets to achieve the purpose of preventing accidental contact. However, the insulating parts are troublesome to insert and remove, and are easy to lose. The protection for children is still poor, the protection effect is not good, and the comfort of using electricity is not considered. Moreover, there is no function to identify the access of electrical equipment, and the consideration of electrical safety is ignored to a certain extent.

[0046] Considering that electrical sockets usually use insulating parts inserted into the sockets to achieve the purpose of preventing accidental contact, but there is no automatic access identification function, the power supply ports are energized for a long time, the protection for children is relatively poor, and the protection effect is not good. In addition, when other conductive objects are inserted into the power supply ports, it will cause a short circuit in the power consumption system, thus triggering safety problems. Moreover, when the power supply ports are energized, there is no display function, and it is impossible to intuitively know whether the power supply ports are energized. The solution of the present invention provides an intelligent socket system with an automatic access identification function. It has an automatic access identification function. By setting metal false feet on the plug, corresponding metal false foot jacks on the socket, and a power supply port detection circuit of the socket inside the socket, only when the plug is inserted into the socket, the metal false feet are inserted into the metal false foot jacks, and the current in the branch where the metal false foot jack is located in the power supply port detection circuit meets the set conditions, can it control the power-on of the strong power port of the socket, and then the plug is powered on. The protection performance is good and safe power-on can be ensured.

[0047] In some embodiments, the number of the metal false feet is more than one. The number of the metal false foot jacks is the same as the number of the metal false feet.

[0048] The solution of the present invention is applicable to other places such as DC interfaces, single-phase AC interfaces, and three-phase AC interfaces, greatly improving the user-side electrical safety of electrical equipment such as photovoltaic air conditioners, inverters, and even other sockets.

[0049] In some embodiments, when the number of the metal false feet is two, the number of the metal false foot jacks is also two.

[0050] The two metal false foot jacks include: a first jack (11) and a second jack (12).

[0051] The two metal prosthetic feet include: a first metal prosthetic foot (21) and a second metal prosthetic foot (22).

[0052] The solution of the present invention also addresses the problem of electrical safety in a photovoltaic air - conditioning system, and proposes a photovoltaic air - conditioning power - using system with automatic access recognition. Figure 2 It is a schematic structural diagram of an embodiment of a photovoltaic community power - using system. The automatic access recognition photovoltaic air - conditioning power - using system and intelligent socket proposed by the solution of the present invention can be seen Figure 2 in the example shown.

[0053] In a photovoltaic community power - using system as Figure 2 shown, the photovoltaic community directly uses direct current and alternating current. The photovoltaic panel is connected to the power grid via a DC / AC module (i.e., a direct - current - to - alternating - current conversion module). Electrical equipment such as a photovoltaic air - conditioner is connected to the line between the photovoltaic panel and the DC / AC module. The user - side jack with a prosthetic foot on the DC side is also connected to the line between the photovoltaic panel and the DC / AC module. The user - side jack with a prosthetic foot on the AC side is connected to the line between the DC / AC module and the power grid.

[0054] Figure 3 It is a schematic structural diagram of a user - side jack with a prosthetic foot. Among them, (a) is a schematic structural diagram of a user - side jack with a prosthetic foot on the AC side, and (b) is a schematic structural diagram of a user - side jack with a prosthetic foot on the DC side. By adding prosthetic feet (such as a first prosthetic foot 21 and a second prosthetic foot 22) to the plug of the electrical equipment, it is used for physical recognition with the jack of the socket power - supply port. The prosthetic foot is a metal prosthetic foot without any electrical connection and is not charged.

[0055] In the solution of the present invention, by adding metal prosthetic feet (such as a first prosthetic foot 21 and a second prosthetic foot 22) to the plug of the electrical equipment, adding prosthetic - foot jacks, a controller (such as a DSP control chip), a current sensor in the socket power - supply port, and adding a relay to the strong - electricity port, etc., a detection and control circuit is constructed, realizing the functions of automatic recognition, judgment, and power - on (the power supply powers the strong - electricity port, that is, the strong - electricity port of the socket is powered on) of the intelligent socket system after the electrical equipment is inserted into the socket power - supply port. Among them, the prosthetic - foot jacks are, for example, a first jack (i.e., the first prosthetic - foot jack) 11 and a second jack (i.e., the second prosthetic - foot jack) 12.

[0056] In some embodiments, the jack control unit includes: a detection module and a switch module.

[0057] Among them, the jack control unit controls the plug to be connected to the power supply through the socket only when the plug pin is inserted into the socket power - supply jack, the metal prosthetic foot is inserted into the metal prosthetic - foot jack, and the parameters of the metal prosthetic - foot jack meet the set conditions, including:

[0058] The detection module is configured to detect whether there are parameters in the metal dummy pin jack when the plug pin is inserted into the socket power supply jack and the metal dummy pin is inserted into the metal dummy pin jack, and when there are parameters in the metal dummy pin jack, detect whether the parameters of the metal dummy pin jack meet the set conditions, so as to send a closing instruction when the plug pin is inserted into the socket power supply jack, the metal dummy pin is inserted into the metal dummy pin jack, and the parameters of the metal dummy pin jack meet the set conditions.

[0059] The switch module is configured to, when receiving the closing instruction, convert itself from the off state to the on state, so that the plug is connected to the power supply through the socket.

[0060] In the solution of the present invention, by providing the first dummy pin 21 and the second dummy pin 22, as well as the first jack 11 and the second jack 12 in the plug and the socket, it is realized that when there is no electrical device connected to the intelligent socket system, the power supply port of the socket in the intelligent socket system is not powered. After the electrical device is connected, it automatically recognizes the device connection and controls the relay (such as relay K1) to close, so that the power supply terminal of the socket power supply port is powered and then powers the electrical device.

[0061] In some embodiments, the detection module includes: a sampling module and a control module. The sampling module is connected to the control module.

[0062] Wherein, the sampling module is configured to sample the parameters of the sampling branch where the sampling module itself is located as the parameters of the metal dummy pin jack in the sampling branch where the sampling module itself is located, such as the current of the metal dummy pin jack.

[0063] The control module is configured to detect whether there are parameters in the metal dummy pin jack when the plug pin is inserted into the socket power supply jack and the metal dummy pin is inserted into the metal dummy pin jack, and when there are parameters in the metal dummy pin jack, detect whether the parameters of the metal dummy pin jack meet the set conditions.

[0064] Figure 4 It is a schematic structural diagram of an embodiment of the DC port detection circuit on the power supply side. In the example as Figure 4 shown, compared with the socket in the related solution, two additional dummy pin jacks (such as the first jack 11 and the second jack 12) and a detection and logic processing circuit are added. Figure 4 In the example shown, it can display the DC socket circuit, and it can be realized that when there is no plug inserted into the socket, the power supply port of the socket is not powered, and even if the hand touches the conductor inside the socket, there will be no electric shock. After a plug is inserted into the socket, it automatically recognizes and controls the jack to be powered, realizing electrical safety.

[0065] Figure 5 It is a schematic structural diagram of an embodiment of the AC port detection circuit on the power supply side. In the example as shown in Figure 5 In the example shown, compared with the socket in the related solution, two dummy pin jacks (such as the first jack 11 and the second jack 12) and a detection and logic processing circuit are added. Figure 5 In the example shown, it can display the AC power supply socket circuit, and it can achieve that when there is no plug inserted into the socket, the power supply port of the socket is not charged, and even if a hand touches the conductor inside the socket, there will be no electric shock. After a plug is inserted into the socket, it can be automatically recognized and the jack is controlled to be powered, realizing electrical safety.

[0066] In some embodiments, the sampling module includes: sampling branches with the same number as the metal dummy pin jacks.

[0067] Each sampling branch includes: a current limiting module and a sampling module. The current limiting module, such as a current limiting resistor, such as at least one of resistor R1 and resistor R2, etc. In each sampling branch, a DC power supply with a set voltage range, such as a +5V power supply, is connected to the first connection end of a metal dummy pin jack corresponding to this sampling branch through the current limiting module. The second connection end of this metal dummy pin jack is grounded after passing through the sampling module.

[0068] In different sampling branches, the resistance values of the current limiting modules are all different.

[0069] In the solution of the present invention, through this intelligent socket system with an automatic access recognition function, when there is no electrical equipment connected, its power supply port is not charged, and even if touched, there will be no electric shock, which can effectively prevent children from accidentally touching and getting an electric shock. When there is an electrical equipment connected, after the electrical equipment is connected, it is automatically recognized by the control end, and then the control end of the relay K1 controls the power supply terminal of the socket power supply port to be charged. In this way, the control end of the relay K1 controls whether the power supply terminal of the power supply port is charged, which has high safety. When a conductive object is inserted, the intelligent socket system with an automatic access recognition function will automatically recognize different abnormal situations and display them through the protection lamp. At this time, the strong electricity is not powered. The power supply port of the socket has a power-on prompt function. When the strong electricity end is powered, the green light-emitting diode at the control end is always on to prompt the user to pay attention to electrical safety.

[0070] In some embodiments, the switch module includes: a relay, such as relay K1.

[0071] The coil of the relay is connected to the control module. The normally open contact of the relay is arranged between the socket power supply jack and the power supply.

[0072] Different from Figure 4 the example shown inFigure 5 In the example shown, the first normally open contact of the relay K1 is set between the neutral jack of the socket and the neutral line N of the AC power supply. The second normally open contact of the relay K2 is set between the live jack of the socket and the live line L of the AC power supply.

[0073] In some embodiments, it further includes at least one of a display module and a reminder module to perform the process of reminding of abnormal situations of the metal false foot jack.

[0074] Wherein, the display module is configured to display the connection situation between the plug and the socket when controlling the plug to be connected to the power supply through the socket; and / or, the detection module is further configured to send a reminder instruction when the plug pin is inserted into the power supply jack of the socket, the metal false foot is inserted into the metal false foot jack, and the parameters of the metal false foot jack do not meet the set conditions.

[0075] The reminder module is configured to initiate a reminder message that the metal false foot jack is abnormal when receiving the reminder instruction.

[0076] In the solution of the present invention, when other conductive objects are inserted, the intelligent socket system will automatically identify different abnormal situations and display them through the protection lamp. At this time, the strong electricity is not powered on, effectively protecting the life and property safety of users.

[0077] In some embodiments, the reminder module includes at least one of a first light-emitting diode module and a second light-emitting diode module. The first light-emitting diode module is, for example, the diode D1. The second light-emitting diode module is, for example, the diode D2.

[0078] Wherein, when the reminder module includes the first light-emitting diode module and the switch module is a relay, the first light-emitting diode module is set between the control module and the coil of the relay. One output terminal of the control module is connected to the anode of the first light-emitting diode module.

[0079] When the reminder module includes the second light-emitting diode module, the other output terminal of the control module is connected to the anode of the second light-emitting diode module. The cathode of the second light-emitting diode module is grounded.

[0080] In the solution of the present invention, when the strong electricity port in the socket power supply port is charged (that is, the electrical equipment is using electricity), the DSP control chip will control the light-emitting diode of the first set color (such as green) to be constantly on, indicating that the strong electricity port in the socket power supply port is charged, and reminding the user to pay attention to electricity safety.

[0081] In some embodiments, a current limiting module is provided between the first light emitting diode module and the coil of the relay. A second current limiting module is provided between the second light emitting diode and the ground.

[0082] As Figure 4 shown, the power supply side DC port detection circuit includes: resistor R1, resistor R2, resistor R3, resistor R4, relay K1, diodes D1, D2, DSP control chip U3, current sensors U1, U2, first jack 11, and second jack 12.

[0083] In Figure 4 the example shown, the +5V DC power supply is grounded after passing through resistor R1, first jack 11, and current sensor U1. The +5V DC power supply is also grounded after passing through resistor R2, second jack 12, and current sensor U2. Current sensor U1 outputs current I1 to the first input terminal of DSP control chip U3, and current sensor U2 outputs current I2 to the second input terminal of DSP control chip U3. The first output terminal of DSP control chip U3 is connected to the anode of diode D1. The cathode of diode D1 is connected to the coil of relay K1 through resistor R3. The first normally open contact of relay K1 is provided between the negative jack of the socket and the negative pole of the DC power supply. The second normally open contact of relay K2 is provided between the positive jack of the socket and the positive pole of the DC power supply. The second output terminal of DSP control chip U3 is connected to the anode of diode D2. The cathode of diode D2 is grounded through resistor R4.

[0084] In Figure 4 the example shown, diode D1 is a light emitting diode of the first set color (such as green) for identifying whether the high-voltage port is energized. Diode D2 is a light emitting diode of the second set color (such as red), also called an alarm lamp. When the intelligent socket system detects and determines an abnormal conduction insertion, the alarm lamp or the fault lamp flashes for warning. The first jack 11 and the second jack 12 are the jacks of the dummy pins on the electrical device plug for detecting whether the plug is inserted into the jack. U1 and U2 are current sensors for detecting the current in their respective circuits to determine whether there is another conductor inserted into the first jack 11 and the second jack 12. The sampling value of current sensor U1 is current I1, and the sampling value of current sensor U2 is current I2. Relay K1 is a double-pole normally open relay for controlling whether the high-voltage port is powered on.

[0085] Resistors R1, R2, R3, and R4 are all current-limiting resistors. Among them, the resistance values R1 ≠ R2, and the purpose is to make I1 ≠ I2 so that the software can perform comparison processing. Resistor R3 only needs to ensure the safe current at the control end of relay K1, and resistor R4 should be as small as possible while ensuring the safe current of diode D2, so that the alarm light such as diode D2 can flash as obviously as possible.

[0086] As Figure 4 and Figure 5 In the example shown, under normal circumstances, the two +5V circuits are disconnected, that is, the currents detected by current sensors U1 and U2 are 0. At this time, the intelligent socket system determines that no conductor is inserted into the first jack 11 and the second jack 12, and relay K1 is not energized, that is, the strong power port is not energized. At this time, only the side of the dummy foot jack has a 5V voltage. Checking the data shows that the self-impedance of the human body is about 100,000 Ω when touching low voltage, so there will be no electric shock.

[0087] Figure 6 It is the flashing rule table for the alarm light such as diode D2. Among them, "——" means D2 flashes slowly, and "." means D2 flashes quickly. In Figure 4 and Figure 5 In the example shown, when the branch where the first jack 11 is located is conducting, diode D2 first flashes slowly and then quickly. When the branch where the second jack 12 is located is conducting, diode D2 first flashes quickly and then slowly. When the first jack 11 and the second jack 12 are short-circuited, diode D2 flashes continuously and quickly.

[0088] Figure 7 It is a simplified structural schematic diagram of the short circuit of the two dummy feet. Figure 7 In the example shown, it simulates inserting conductors into the first jack 11 and the second jack 12 at the same time. Assume a situation where tweezers are inserted into the two dummy foot jacks respectively and then the two dummy foot jacks are short-circuited.

[0089] In some embodiments, where the number of the metal dummy foot jacks is one, the set condition is that the parameters of the metal dummy foot jack meet the set value.

[0090] When the number of the metal dummy foot jacks is more than two, the set condition is that the parameters of different metal dummy foot jacks are all different, and the parameter values of each metal dummy foot jack meet the corresponding set values.

[0091] Figure 8 It is a control logic schematic diagram of an embodiment of the intelligent socket system. As Figure 8 shown, when the intelligent socket system is running, the control process of the intelligent socket system includes:

[0092] Step 1: The intelligent socket system starts to determine whether there is a conductor inserted into either of the two jacks. If so, go to Step 2. Otherwise, return to Step 1.

[0093] Step 2: When a conductor is inserted into the jack, the intelligent socket system starts to determine whether there are conductors inserted into both jacks. If so, go to Step 3. Otherwise, go to Step 4.

[0094] As Figure 4 shown, it can be found that the first jack 11 is not a closed loop. It can be understood as two semi - circles that are not electrically connected. That is, the loop of resistor R1, the first jack 11, and the current sensor U1 is open - circuited, and naturally the current sensor U1 cannot detect current. When the false foot is inserted, it plays a connecting role and connects the two semi - circles. At this time, resistor R1, the first jack 11, the first false foot 21, and the current sensor U1 form a complete loop, and the current value is a fixed value. If the current I1 detected by the DSP chip is equal to the threshold Ref1, it is determined that there is a conductor inserted into the first jack 11.

[0095] Step 3: When the intelligent socket system detects that conductors are inserted into both the first jack 11 and the second jack 12, the DC current sensors U1 and U2 detect different currents I1 and I2 and transmit them to the DSP control chip U3 for processing.

[0096] Specifically, the DSP control chip U3 determines whether I1≠I2, I1 = Ref1, and I2 = Ref2 are satisfied. If so, go to Step 31. Otherwise, go to Step 32. Ref1 and Ref2 are comparison values set inside the software.

[0097] Step 31: If the DSP control chip U3 determines that I1≠I2, I1 = Ref1, and I2 = Ref2 are satisfied, that is, when the software determines that I1≠I2, I1 = Ref1, and I2 = Ref2, the intelligent socket system determines that the false - foot access recognition is normal. At this time, the DSP control chip U3 controls the relay K1 to conduct, enabling the power - strong port to be powered on to supply power to the electrical device, and at the same time, the diode D1 is constantly on to remind the user of electrical safety.

[0098] Assume that the gains of the current sensors U1 and U2 themselves are a, then I1 = Ref1 = 5 / R1*a, and I2 = Ref2 = 5 / R2*a.

[0099] Step 32: If the DSP control chip U3 determines that I1≠I2, I1 = Ref1, and I2 = Ref2 are not satisfied, it is considered that the first jack 11 and the second jack 12 are short - circuited, and the diode D2 flashes quickly to give a warning.

[0100] Assume R1 <R2,若此时I1=I2=5 / ((R1*R2) / (R1+R2))<Ref2<Ref1。则判断智能插座系统有异常导体将第一插孔11和第二插孔12被短接,此时二极管D2会按照设置的规律进行闪烁,其简化图参见 Figure 7 In this process, the highest voltage that the human body can touch is 5V, so there is no safety problem.

[0101] Step 4: If the smart socket system detects that only the first jack 11 or the second jack 12 has a conductor connected, it is determined that other abnormal conductors are connected to the smart socket system. The DSP control chip U3 will send out different pulses to control the alarm light such as the diode D2 to flash according to a certain length rule. The flashing is repeated for 2 times in a group. The flashing rule is shown in Figure 6 Example shown.

[0102] Specifically, when the first jack 11 is turned on, the diode D2 flashes long and short, and when the second jack 12 is turned on, the diode D2 flashes short and long.

[0103] The solution of the present invention adds automatic access identification function, other abnormal conductor insertion alarm function, and interface live prompt function. In abnormal circumstances, all system high-voltage ports shall not be powered, which can effectively prevent safety issues such as electric shock caused by accidental touch by children and electric shock caused by abnormal conductor insertion.

[0104] According to the technical solution of the present invention, a metal prosthetic foot is provided on the plug, a metal prosthetic foot jack corresponding to the metal prosthetic foot is provided on the socket, and a power supply port detection circuit of the socket is also provided inside the socket. Only when the plug is inserted into the socket, the metal prosthetic foot is inserted into the metal prosthetic foot jack, and the current of the branch where the metal prosthetic foot jack is located in the power supply port detection circuit meets the set conditions, can the high-voltage port of the socket be controlled to be energized, and then the plug is energized. Therefore, by enabling the socket system to have an access identification function, the safety protection performance can be improved.

[0105] According to an embodiment of the present invention, an electric device corresponding to the socket system is also provided. The electric device may include: the socket system described above.

[0106] Since the processing and functions implemented by the electrical equipment of this embodiment basically correspond to the embodiments, principles and examples of the aforementioned devices, for the details not fully described in this embodiment, please refer to the relevant descriptions in the aforementioned embodiments, and no further elaboration will be made here.

[0107] Adopting the technical solution of the present invention, by providing metal false feet on the plug, metal false foot jacks corresponding to the metal false feet on the socket, and a power supply port detection circuit of the socket inside the socket, only when the plug is inserted into the socket, the metal false feet are inserted into the metal false foot jacks, and the current in the branch of the metal false foot jack in the power supply port detection circuit meets the set conditions, can the power of the strong electricity port of the socket be controlled, and then the plug is powered on, which can improve the electrical safety of users when using the socket.

[0108] According to an embodiment of the present invention, a control method for a socket system corresponding to an electrical device is also provided. The control method of the socket system may include: through the jack control unit, only when the plug pin is inserted into the socket power supply jack, the metal false foot is inserted into the metal false foot jack, and the parameters of the metal false foot jack meet the set conditions, the plug is controlled to be connected to the power supply through the socket, that is, the socket power supply jack is powered on.

[0109] The solution of the present invention provides an intelligent socket system with an automatic access recognition function. It has an automatic access recognition function. By providing metal false feet on the plug, metal false foot jacks corresponding to the metal false feet on the socket, and a power supply port detection circuit of the socket inside the socket, only when the plug is inserted into the socket, the metal false feet are inserted into the metal false foot jacks, and the current in the branch of the metal false foot jack in the power supply port detection circuit meets the set conditions, can the power of the strong electricity port of the socket be controlled, and then the plug is powered on. It has good protection performance and can ensure safe power on.

[0110] In some embodiments, the specific process of controlling the plug to be connected to the power supply through the socket by the jack control unit only when the plug pin is inserted into the socket power supply jack, the metal false foot is inserted into the metal false foot jack, and the parameters of the metal false foot jack meet the set conditions is shown in the following exemplary description.

[0111] The following combines Figure 9 The schematic flowchart of an embodiment of controlling the plug to be connected to the power supply through the socket in the method of the present invention shown in the figure further illustrates the specific process of controlling the plug to be connected to the power supply through the socket, including: step S110 and step S120.

[0112] Step S110: Through the detection module, when the plug pin is inserted into the socket power supply jack and the metal dummy foot is inserted into the metal dummy foot jack, detect whether there are parameters in the metal dummy foot jack, and when there are parameters in the metal dummy foot jack, detect whether the parameters of the metal dummy foot jack meet the set conditions, so as to send a closing instruction when the plug pin is inserted into the socket power supply jack, the metal dummy foot is inserted into the metal dummy foot jack, and the parameters of the metal dummy foot jack meet the set conditions.

[0113] In some embodiments, in step S110, through the detection module, when the plug pin is inserted into the socket power supply jack and the metal dummy foot is inserted into the metal dummy foot jack, detect whether there are parameters in the metal dummy foot jack, and when there are parameters in the metal dummy foot jack, detect whether the parameters of the metal dummy foot jack meet the set conditions. For the specific process, refer to the following exemplary description.

[0114] The following combines Figure 10 The schematic flow chart of an embodiment for detecting the parameters of the metal dummy foot jack in the method of the present invention shown in the figure further illustrates the specific process of detecting the parameters of the metal dummy foot jack in step S110, including: step S210 and step S220.

[0115] Step S210: Through the sampling module, sample the parameters of the sampling branch where the sampling module itself is located as the parameters of the metal dummy foot jack in the sampling branch where the sampling module itself is located, such as the current of the metal dummy foot jack.

[0116] Step S220: Through the control module, when the plug pin is inserted into the socket power supply jack and the metal dummy foot is inserted into the metal dummy foot jack, detect whether there are parameters in the metal dummy foot jack, and when there are parameters in the metal dummy foot jack, detect whether the parameters of the metal dummy foot jack meet the set conditions.

[0117] Figure 4 It is a schematic structural diagram of an embodiment of the power supply side DC port detection circuit. In the example shown in Figure 4 the figure, compared with the socket in the related solution, two dummy foot jacks (such as the first jack 11 and the second jack 12) and a detection and logic processing circuit are added. Figure 4 In the example shown in the figure, the DC socket circuit can be displayed, and it can be realized that when there is no plug inserted into the socket, the power supply port of the socket is not powered, and even if the hand touches the conductor inside the socket, there will be no electric shock. After a plug is inserted into the socket, it can be automatically recognized and the jack is controlled to be powered, realizing electrical safety.

[0118] Figure 5 It is a schematic structural diagram of an embodiment of the power supply side AC port detection circuit. In the example shown inFigure 5 In the example shown, compared with the socket in the related solution, two dummy pin jacks (such as the first jack 11 and the second jack 12) and a detection and logic processing circuit are added. Figure 5 In the example shown, an AC power supply socket circuit can be displayed. When no plug is inserted into the socket, the power supply port of the socket is not energized, and even if a hand touches the conductive body inside the socket, there will be no electric shock. After a plug is inserted into the socket, it is automatically recognized and the jack is controlled to be energized, achieving electrical safety.

[0119] And Figure 4 Different from the example shown, in Figure 5 In the example shown, the first normally open contact of the relay K1 is arranged between the neutral jack of the socket and the neutral line N of the AC power supply. The second normally open contact of the relay K2 is arranged between the live jack of the socket and the live line L of the AC power supply.

[0120] Step S120: Through the switch module, when the closing instruction is received, the switch module itself is changed from the off state to the on state, so that the plug is connected to the power supply through the socket.

[0121] In the solution of the present invention, by arranging the first dummy pin 21, the second dummy pin 22, the first jack 11 and the second jack 12 in the plug and the socket, when no electrical equipment is connected, the power supply port of the socket in the intelligent socket system is not energized. After the electrical equipment is connected, it automatically recognizes the connection of the equipment and controls the relay (such as the relay K1) to close, so that the power supply terminal of the socket power supply port is energized to supply power to the electrical equipment.

[0122] In the solution of the present invention, through the intelligent socket system with an automatic access recognition function, when no electrical equipment is connected, its power supply port is not energized, and even if touched, there will be no electric shock, which can effectively prevent children from accidentally touching and getting an electric shock. When an electrical equipment is connected, after the electrical equipment is connected, it is automatically recognized by the control end, and then the control end of the relay K1 controls the power supply terminal of the socket power supply port to be energized. In this way, the control end of the relay K1 controls whether the power supply terminal of the power supply port is energized, which has high safety. When a conductive object is inserted, the intelligent socket system with an automatic access recognition function will automatically recognize different abnormal situations and display them through the protection lamp. At this time, the strong electricity is not energized. The power supply port of the socket has a power-on prompt function. When the strong electricity end is energized, the green light-emitting diode at the control end is always on to prompt the user to pay attention to electrical safety.

[0123] In some embodiments, it further includes: a process of reminding of abnormal situations of the metal dummy pin jacks.

[0124] Next, in combination with Figure 11Schematic diagram of a flowchart of an embodiment for reminding of abnormal metal prosthetic foot jacks in the method of the present invention, further illustrating the specific process of reminding of abnormal metal prosthetic foot jacks, including: step S310 and step S320.

[0125] Step S310, through a display module, when controlling the plug to be connected to a power supply through the socket, display the connection situation between the plug and the socket; and / or, through a control module, also send a reminder instruction when the plug pins are inserted into the socket power supply jacks, the metal prosthetic feet are inserted into the metal prosthetic foot jacks, and the parameters of the metal prosthetic foot jacks do not meet the set conditions.

[0126] Step S320, through a reminder module, when receiving the reminder instruction, initiate a reminder message that the metal prosthetic foot jack is abnormal.

[0127] In the solution of the present invention, when other conductive objects are inserted, the intelligent socket system will automatically identify different abnormal situations and display them through a protection lamp. At this time, the strong electricity is not powered on, effectively protecting the life and property safety of users.

[0128] In the solution of the present invention, when the strong electricity port in the socket power supply port is charged (i.e., the electrical equipment is in use), the DSP control chip will control the light-emitting diode of the first set color (such as green) to be constantly on, indicating that the strong electricity port in the socket power supply port is charged, and reminding the user to pay attention to electrical safety.

[0129] As Figure 4 Shown, the power supply side DC port detection circuit includes: resistor R1, resistor R2, resistor R3, resistor R4, relay K1, diode D1, diode D2, DSP control chip U3, current sensor U1, current sensor U2, first jack 11, second jack 12.

[0130] In Figure 4In the example shown, the +5V DC power supply is grounded after passing through resistor R1, the first jack 11, and the current sensor U1. The +5V DC power supply is also grounded after passing through resistor R2, the second jack 12, and the current sensor U2. The current sensor U1 outputs current I1 to the first input terminal of the DSP control chip U3, and the current sensor U2 outputs current I2 to the second input terminal of the DSP control chip U3. The first output terminal of the DSP control chip U3 is connected to the anode of the diode D1. The cathode of the diode D1 is connected to the coil of the relay K1 after passing through resistor R3. The first normally open contact of the relay K1 is set between the negative jack of the socket and the negative pole of the DC power supply. The second normally open contact of the relay K2 is set between the positive jack of the socket and the positive pole of the DC power supply. The second output terminal of the DSP control chip U3 is connected to the anode of the diode D2. The cathode of the diode D2 is grounded after passing through resistor R4.

[0131] In Figure 4 In the example shown, the diode D1 is a light-emitting diode of the first set color (such as green), used to identify whether the high-voltage port is energized. The diode D2 is a light-emitting diode of the second set color (such as red), also called an alarm light. When the intelligent socket system detects and determines an abnormal conduction insertion, the alarm light or the fault light flashes to give a warning. The first jack 11 and the second jack 12 are the jacks for the dummy pins on the electrical equipment plug, used to detect whether the plug is inserted into the jack. U1 and U2 are current sensors, used to detect the current in their respective circuits to determine whether there is another conductor inserted into the first jack 11 and the second jack 12. The sampling value of the current sensor U1 is the current I1, and the sampling value of the current sensor U2 is the current I2. The relay K1 is a double-pole normally open relay, used to control whether the high-voltage port is powered on.

[0132] Resistors R1, R2, R3, and R4 are all current-limiting resistors. Among them, the resistance value R1 ≠ R2, and the purpose is to make I1 ≠ I2 for software comparison processing. The resistor R3 only needs to ensure the safe current at the control end of the relay K1, and the resistor R4 should be as small as possible while ensuring the safe current of the diode D2, so that the alarm light such as the diode D2 flashes as obviously as possible.

[0133] Such as Figure 4 And Figure 5 In the example shown, under normal circumstances, the two +5V circuits are disconnected, that is, the currents detected by the current sensors U1 and U2 are 0. At this time, the intelligent socket system determines that there is no conductor inserted into the first jack 11 and the second jack 12, and the relay K1 is not powered on, that is, the high-voltage port is not powered on. At this time, only the side of the dummy pin jack has a 5V voltage. Checking the data shows that the self-impedance of the human body is about 100,000 Ω when touching low voltage, so there will be no electric shock.

[0134] Figure 6It is a flashing rule table for an alarm lamp such as diode D2. Herein, "——" indicates that D2 flashes slowly, and "." indicates that D2 flashes quickly. In Figure 4 and Figure 5 In the shown example, when the branch where the first jack 11 is located is conducting, diode D2 first flashes slowly and then quickly. When the branch where the second jack 12 is located is conducting, diode D2 first flashes quickly and then slowly. When the first jack 11 and the second jack 12 are short-circuited, diode D2 flashes continuously and quickly.

[0135] Figure 7 It is a simplified structural schematic diagram of two false feet being short-circuited. Figure 7 In the shown example, it simulates inserting conductors into the first jack 11 and the second jack 12 simultaneously. Assume that tweezers are inserted into two false foot jacks respectively, and then a situation where the two false foot jacks are short-circuited.

[0136] In some embodiments, when the number of the metal false foot jacks is one, the set condition is that the parameters of the metal false foot jack satisfy the set value.

[0137] When the number of the metal false foot jacks is more than two, the set condition is that the parameters of different metal false foot jacks are all different, and the parameter value of each metal false foot jack satisfies the corresponding set value.

[0138] Figure 8 It is a control logic schematic diagram of an embodiment of the intelligent socket system. As Figure 8 shown, when the intelligent socket system is running, the control process of the intelligent socket system includes:

[0139] Step 1: The intelligent socket system starts to judge whether there is a conductor inserted into the two jacks. If so, go to Step 2. Otherwise, return to Step 1.

[0140] Step 2: When there is a conductor inserted into the jack, the intelligent socket system starts to judge whether there are conductors inserted into both jacks. If so, go to Step 3. Otherwise, go to Step 4.

[0141] Step 3: If the intelligent socket system detects that conductors are inserted into both the first jack 11 and the second jack 12, the DC current sensors U1 and U2 detect different currents I1 and I2 and transmit them to the DSP control chip U3 for processing.

[0142] Specifically, the DSP control chip U3 judges whether I1≠I2, I1 = Ref1, and I2 = Ref2 are satisfied. If so, go to Step 31. Otherwise, go to Step 32. Ref1 and Ref2 are comparison values set inside the software.

[0143] Step 31: If the DSP control chip U3 determines that I1≠I2, I1 = Ref1, and I2 = Ref2 are satisfied, that is, when the software determines that I1≠I2, and I1 = Ref1, I2 = Ref2, the intelligent socket system determines that the prosthesis access recognition is normal. At this time, the DSP control chip U3 controls the relay K1 to conduct, enabling the power port to be energized and supplying power to the electrical equipment. At the same time, the diode D1 is always on to remind the user of electrical safety.

[0144] Assume that the gains of the current sensor U1 and the current sensor U2 are both a. Then I1 = Ref1 = 5 / R1 * a, and I2 = Ref2 = 5 / R2 * a.

[0145] Step 32: If the DSP control chip U3 determines that I1≠I2, I1 = Ref1, and I2 = Ref2 are not satisfied, it is considered that the first jack 11 and the second jack 12 are short-circuited, and the diode D2 flashes quickly to give a warning.

[0146] Assume that R1 < R2. If at this time I1 = I2 = 5 / ((R1 * R2) / (R1 + R2)) < Ref2 < Ref1, it is determined that there is an abnormal conductor in the intelligent socket system short-circuiting the first jack 11 and the second jack 12. At this time, the diode D2 will flash according to the set rule, and its simplified diagram is shown in Figure 7 the example shown. During this process, the highest voltage that a human body contacts is 5V, so there will be no safety problem.

[0147] Step 4: If the intelligent socket system detects that there is a conductor inserted only in the first jack 11 or the second jack 12, it is determined that there is an abnormal conductor inserted into the intelligent socket system. The DSP control chip U3 will emit different pulses to control the alarm light, such as the diode D2, to flash according to a certain long and short rule, with 2 flashes as a group and repeating continuously. Its flashing rule is shown in Figure 6 the example shown.

[0148] Specifically, when the first jack 11 is conducting, the diode D2 flashes long and then short. When the second jack 12 is conducting, the diode D2 flashes short and then long.

[0149] The solution of the present invention, by adding functions such as automatic access recognition, alarm function for inserting other abnormal conductors, and interface live reminder function. In abnormal situations, the power port of the system is not energized, which can effectively prevent safety problems such as children accidentally touching and getting an electric shock, and getting an electric shock due to inserting an abnormal conductor.

Furthermore, the plug is powered on, ensuring the normal power supply of the electrical equipment and the safe power use of the user.
