The reminding module comprises the first light-emitting diode module, and the first light-emitting diode module is arranged between the control module and the coil of the relay under the condition that the switch module is the relay. And one output end of the control module is connected with the anode of the first light-emitting diode module.

And under the condition that the reminding module comprises the second light-emitting diode module, the other output end of the control module is connected with the anode of the second light-emitting diode module. And the cathode of the second light-emitting diode module is grounded.

In the scheme of the utility model, when a strong current port in the socket power supply port is electrified (i.e. the electric equipment is being electrified), the DSP control chip controls the light emitting diode with the first set color (such as green) to be normally on, which represents that the strong current port in the socket power supply port is electrified, and prompts a user to pay attention to the electricity utilization safety.

In some embodiments, a current limiting module is disposed between the first led module and the coil of the relay. And a second current limiting module is arranged between the second light emitting diode and the ground.

As shown in fig. 4, the power supply side dc port detection circuit includes: resistance R1, resistance R2, resistance R3, resistance R4, relay K1, diode D1, diode D2, DSP control chip U3, current sensor U1, current sensor U2, first jack 11, second jack 12.

In the example shown in fig. 4, dc +5V is grounded via the resistor R1, the first jack 11 and the current sensor U1. The +5V direct current is grounded through a resistor R2, the second jack 12 and a current sensor U2. The current sensor U1 outputs a current I1 to a first input terminal of the DSP control chip U3, and the current sensor U2 outputs a current I2 to a 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 via the resistor R3. And a first normally open contact of the relay K1 is arranged between the negative electrode jack of the socket and the negative electrode of the direct-current power supply. And a second normally open contact of the relay K2 is arranged between the positive electrode jack of the socket and the positive electrode of the direct-current power supply. And a second output end of the DSP control chip U3 is connected to the anode of the diode D2. The cathode of the diode D2 is grounded through a resistor R4.

In the example shown in fig. 4, the diode D1 is a first color-setting (e.g., green) light emitting diode for identifying whether the strong power port is charged. Diode D2 is a second light emitting diode of a set color (e.g., red), also called a warning light, which flashes and warns when the smart socket system detects and determines an abnormal conductive plug-in. The first jack 11 and the second jack 12 are jacks of a prosthetic foot on a plug of the electric equipment and are used for detecting whether the plug is inserted into the jacks. U1 and U2 are current sensors for detecting the current on the respective loops to determine whether other conductors are inserted into the first jack 11 and the second jack 12. The current sensor U1 samples current I1 and the current sensor U2 samples current I2. Relay K1 is a double-pole normally open relay for controlling whether the strong current port is energized.

The resistor R1, the resistor R2, the resistor R3 and the resistor R4 are all current-limiting resistors, wherein the resistance value R1 is not equal to R2, and the purpose is to enable I1 to be not equal to I2, so that comparison processing can be performed by software. The resistor R3 ensures that the safe current of the control end of the relay K1 is enough, and the resistor R4 is as small as possible under the condition of ensuring the safe current of the diode D2, so that the alarm lamp such as the diode D2 flickers as obviously as possible.

As in the example shown in fig. 4 and 5, normally, the two +5V loops are open, i.e., the currents detected by the current sensors U1 and U2 are 0. At this time, the smart socket system determines that no conductor is inserted into the first jack 11 and the second jack 12, and the relay K1 is not powered, that is, the strong power port is not powered. Only one side of the prosthetic foot jack is provided with 5V voltage. The data shows that the impedance of the human body is about one hundred thousand omega when the human body touches low voltage, so that the human body does not get an electric shock.

Fig. 6 is a table showing the flashing rules of a warning light such as a diode D2, wherein "-" indicates that D2 is slow flashing and "-" indicates that D2 is fast flashing. In the example shown in fig. 4 and 5, diode D2 flashes slowly before flashing with the branch of the first jack 11 conducting. With the branch of the second jack 12 conducting, the diode D2 flashes first and then slowly. In case the first jack 11 and the second jack 12 are short-circuited, the diode D2 is flash-continuous.

Fig. 7 is a simplified schematic diagram of a two-foot short circuit. Fig. 7 shows an example simulating the simultaneous insertion of conductors in the first jack 11 and the second jack 12. Suppose a situation where forceps are inserted into two prosthetic foot insertion holes, respectively, and then the two prosthetic foot insertion holes are short-circuited.

In some embodiments, wherein the set condition is that a parameter of the metal prosthetic foot insertion hole satisfies a set value in a case where the number of the metal prosthetic foot insertion holes is one.

And under the condition that the number of the metal prosthetic foot jacks is more than two, the set conditions are that the parameters of the metal prosthetic foot jacks are different, and the parameter value of each metal prosthetic foot jack meets the corresponding set value.

Fig. 8 is a control logic diagram of an embodiment of a smart socket system. As shown in fig. 8, when the smart socket system operates, the control flow of the smart socket system includes:

step 1, the intelligent socket system starts to judge whether a conductor is connected into two jacks: if yes, executing step 2. Otherwise, returning to the step 1.

Step 2, when the jack has the conductor to insert, the smart jack system begins to judge whether two jacks all have the conductor to insert: if yes, go to step 3. Otherwise, step 4 is executed.

As shown in fig. 4, it can be seen that the first jack 11 is not a closed-loop circle. It is understood that two semicircles are provided, the two semicircles not being electrically connected. Namely, the resistor R1, the first jack 11 and the current sensor U1 are open circuits, and the current sensor U1 cannot detect the current. When the prosthetic foot is inserted, it acts as a joint connecting the two semi-circles. The resistor R1, the first socket 11, the first prosthetic foot 21 and the current sensor U1 form a complete circuit, and the current value is a constant value. If the current I1 detected by the DSP chip is equal to the threshold Ref1, it is determined that a conductor is inserted into the first insertion hole 11.

And 3, if the intelligent socket system detects that the conductors are inserted into the first jack 11 and the second jack 12, detecting different currents I1 and I2 by the current sensor U1 and the current sensor U2 of the direct current, and transmitting the detected currents I1 and I2 to the DSP control chip U3 for processing.

Specifically, the DSP control chip U3 determines whether I1 ≠ I2, I1 ═ Ref1, and I2 ═ Ref2 are satisfied: if yes, go to step 31. Otherwise, step 32 is performed. Ref1, Ref2 are comparison values set internally in the software.

Step 31, if the DSP control chip U3 determines that I1 ≠ I2, I1 ≠ Ref1, and I2 ═ Ref2 are satisfied, that is, the software determines that I1 ≠ I2, I1 ═ Ref1, and I2 ═ Ref2, the intelligent socket system determines that the prosthetic foot access identification is normal, at this time, the DSP control chip U3 controls the relay K1 to be turned on, so that the strong power port is powered on, power is supplied to the electric equipment, and the diode D1 is normally lit, thereby reminding the user of safety of power utilization.

Assuming that the gains of the current sensor U1 and the current sensor U2 are a, I1 ═ Ref1 ═ 5/R1 ═ a, and I2 ═ Ref2 ═ 5/R2 ×.a.

In step 32, if the DSP control chip U3 determines that I1 ≠ I2, I1 ═ Ref1, and I2 ═ Ref2 are not satisfied, it is determined that the first jack 11 and the second jack 12 are short-circuited, and the diode D2 flashes, thereby giving an alarm.

Let R1< R2, when I1 ═ I2 ═ 5/((R1 × R2)/(R1+ R2)) < Ref2< Ref 1. It is determined that the smart socket system has an abnormal conductor to short-circuit the first jack 11 and the second jack 12, and the diode D2 flickers according to the set rule, which is a simplified example shown in fig. 7. In this process, the maximum voltage of human body contact is 5V, so there is no safety problem.

Step 4, if the smart socket system detects that only the first jack 11 or the second jack 12 has a conductor to be accessed, it is determined that the smart socket system has another abnormal conductor to be accessed, the DSP control chip U3 will send different pulses to control the alarm lamp, such as the diode D2, to flash according to a certain length rule, and the flashing is performed for 2 times as a group and repeated continuously, where the flashing rule refers to the example shown in fig. 6.

Fig. 4 is a schematic structural diagram of an embodiment of a power supply side dc port detection circuit. In the example shown in fig. 4, two prosthetic foot sockets (e.g., first socket 11 and second socket 12) are added, as well as sensing and logic processing circuitry, as compared to the socket in the related solution. The example shown in fig. 4 can show a dc socket circuit, and when a socket is plugged in without a plug, the socket power supply port is not charged, and even if a hand touches a conductor inside the socket, the contact is not made. After the socket is plugged with the plug, the socket is automatically identified, the jacks are controlled to be powered on, and the power utilization safety is realized.

Fig. 5 is a schematic structural diagram of an embodiment of a power supply side ac port detection circuit. In the example shown in fig. 5, two prosthetic foot sockets (e.g., first socket 11 and second socket 12) are added, as well as sensing and logic processing circuitry, as compared to the socket in the related solution. The example shown in fig. 5 can show an ac power supply socket circuit, and when a socket is plugged in without a plug, a socket power supply port is not electrified, and even if a hand touches a conductor inside the socket, the contact is not made. After the socket is plugged with the plug, the socket is automatically identified, the jacks are controlled to be powered on, and the power utilization safety is realized.

In contrast to the example shown in fig. 4, in the example shown in fig. 5, the first normally open contact of the relay K1 is provided between the neutral wire receptacle of the outlet and the neutral wire N of the ac power supply. And a second normally-open contact of the relay K2 is arranged between the live wire jack of the socket and the live wire L of the alternating-current power supply.

And step S120, through a switch module, under the condition that the closing instruction is received, the switch module is switched from an open state to a closed state, so that the plug is communicated with a power supply through the socket.

In the scheme of the utility model, the first artificial foot 21 and the second artificial foot 22, and the first jack 11 and the second jack 12 are arranged in the plug and the socket, so that when no-power equipment is accessed in the intelligent socket system, a socket power supply port in the intelligent socket system is not electrified. After the electric equipment is connected, the automatic identification equipment is connected, and a relay (such as a relay K1) is controlled to be closed, so that a power supply terminal of a socket power supply port is electrified to supply power for the electric equipment.

According to the scheme of the utility model, when the power-free equipment is accessed, the power supply port of the intelligent socket system with the automatic access identification function is not electrified, so that electric shock can not occur even if the intelligent socket system is touched, and the electric shock caused by mistaken touch of children can be effectively prevented. When the electric equipment is connected, the electric equipment is automatically identified by the control end after being connected, and then the control end of the relay K1 controls the power supply terminal of the socket power supply port to be electrified. Thus, the control end of the relay K1 controls whether the power supply terminal of the power supply port is electrified or not, and the safety is high. When the conductive object is inserted, the intelligent socket system with the automatic access recognition function can automatically recognize different abnormal conditions and display the abnormal conditions through the protection lamp, and the strong electricity is not available at the moment. The power supply port of the socket has an electrified prompt function, and when the strong electricity end is electrified, the green light emitting diode at the control end is normally on, so that the user is prompted to pay attention to electricity safety.

In some embodiments, further comprising: and (5) reminding the abnormal condition of the metal prosthetic foot jack.

The following further describes, with reference to a schematic flow chart of an embodiment of the method of the present invention shown in fig. 11, a specific process of reminding an abnormal condition of a metal prosthetic foot jack, including: step S310 and step S320.

Step S310, through a display module, under the condition that the plug is controlled to be communicated with a power supply through the socket, the condition that the plug is communicated with the socket is displayed; and/or sending a reminding instruction through a control module under the condition that 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 parameter of the metal prosthetic foot jack does not meet the set condition.

And step S320, initiating a reminding message that the metal prosthetic foot jack is abnormal through a reminding module under the condition that the reminding instruction is received.

In the scheme of the utility model, when other conductive objects are inserted, the intelligent socket system can automatically identify different abnormal conditions and display the abnormal conditions through the protection lamp, and the strong electricity is not available, so that the life and property safety of a user is effectively protected.

In the scheme of the utility model, when a strong current port in the socket power supply port is electrified (i.e. the electric equipment is being electrified), the DSP control chip controls the light emitting diode with the first set color (such as green) to be normally on, which represents that the strong current port in the socket power supply port is electrified, and prompts a user to pay attention to the electricity utilization safety.

As shown in fig. 4, the power supply side dc port detection circuit includes: resistance R1, resistance R2, resistance R3, resistance R4, relay K1, diode D1, diode D2, DSP control chip U3, current sensor U1, current sensor U2, first jack 11, second jack 12.

In the example shown in fig. 4, dc +5V is grounded via the resistor R1, the first jack 11 and the current sensor U1. The +5V direct current is grounded through a resistor R2, the second jack 12 and a current sensor U2. The current sensor U1 outputs a current I1 to a first input terminal of the DSP control chip U3, and the current sensor U2 outputs a current I2 to a 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 via the resistor R3. And a first normally open contact of the relay K1 is arranged between the negative electrode jack of the socket and the negative electrode of the direct-current power supply. And a second normally open contact of the relay K2 is arranged between the positive electrode jack of the socket and the positive electrode of the direct-current power supply. And a second output end of the DSP control chip U3 is connected to the anode of the diode D2. The cathode of the diode D2 is grounded through a resistor R4.

In the example shown in fig. 4, the diode D1 is a first color-setting (e.g., green) light emitting diode for identifying whether the strong power port is charged. Diode D2 is a second light emitting diode of a set color (e.g., red), also called a warning light, which flashes and warns when the smart socket system detects and determines an abnormal conductive plug-in. The first jack 11 and the second jack 12 are jacks of a prosthetic foot on a plug of the electric equipment and are used for detecting whether the plug is inserted into the jacks. U1 and U2 are current sensors for detecting the current on the respective loops to determine whether other conductors are inserted into the first jack 11 and the second jack 12. The current sensor U1 samples current I1 and the current sensor U2 samples current I2. Relay K1 is a double-pole normally open relay for controlling whether the strong current port is energized.

The resistor R1, the resistor R2, the resistor R3 and the resistor R4 are all current-limiting resistors, wherein the resistance value R1 is not equal to R2, and the purpose is to enable I1 to be not equal to I2, so that comparison processing can be performed by software. The resistor R3 ensures that the safe current of the control end of the relay K1 is enough, and the resistor R4 is as small as possible under the condition of ensuring the safe current of the diode D2, so that the alarm lamp such as the diode D2 flickers as obviously as possible.

As in the example shown in fig. 4 and 5, normally, the two +5V loops are open, i.e., the currents detected by the current sensors U1 and U2 are 0. At this time, the smart socket system determines that no conductor is inserted into the first jack 11 and the second jack 12, and the relay K1 is not powered, that is, the strong power port is not powered. Only one side of the prosthetic foot jack is provided with 5V voltage. The data shows that the impedance of the human body is about one hundred thousand omega when the human body touches low voltage, so that the human body does not get an electric shock.

Fig. 6 is a table showing the flashing rules of a warning light such as a diode D2, wherein "-" indicates a D2 slow flash and "-" indicates a D2 flash. In the example shown in fig. 4 and 5, diode D2 flashes slowly before flashing with the branch of the first jack 11 conducting. With the branch of the second jack 12 conducting, the diode D2 flashes first and then slowly. In case the first jack 11 and the second jack 12 are short-circuited, the diode D2 is flash-continuous.

Fig. 7 is a simplified schematic diagram of a two-foot short circuit. Fig. 7 shows an example simulating the simultaneous insertion of conductors in the first jack 11 and the second jack 12. Suppose a situation where forceps are inserted into two prosthetic foot insertion holes, respectively, and then the two prosthetic foot insertion holes are short-circuited.

In some embodiments, in the case where the number of the metal prosthetic foot insertion holes is one, the set condition is that a parameter of the metal prosthetic foot insertion holes satisfies a set value.

And under the condition that the number of the metal prosthetic foot jacks is more than two, the set conditions are that the parameters of the metal prosthetic foot jacks are different, and the parameter value of each metal prosthetic foot jack meets the corresponding set value.

Fig. 8 is a control logic diagram of an embodiment of a smart socket system. As shown in fig. 8, when the smart socket system operates, the control flow of the smart socket system includes:

step 1, the intelligent socket system starts to judge whether a conductor is connected into two jacks: if yes, executing step 2. Otherwise, returning to the step 1.

Step 2, when the jack has the conductor to insert, the smart jack system begins to judge whether two jacks all have the conductor to insert: if yes, go to step 3. Otherwise, step 4 is executed.

And 3, if the intelligent socket system detects that the conductors are inserted into the first jack 11 and the second jack 12, detecting different currents I1 and I2 by the current sensor U1 and the current sensor U2 of the direct current, and transmitting the detected currents I1 and I2 to the DSP control chip U3 for processing.

Specifically, the DSP control chip U3 determines whether I1 ≠ I2, I1 ═ Ref1, and I2 ═ Ref2 are satisfied: if yes, go to step 31. Otherwise, step 32 is performed. Ref1, Ref2 are comparison values set internally in the software.

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 identification of the prosthetic foot access is normal, at this time, the DSP control chip U3 controls the relay K1 to be turned on, so that the strong power port is powered on, power is supplied to the electric equipment, and the diode D1 is normally lit, thereby reminding the user of safety of power utilization.

Assuming that the gains of the current sensor U1 and the current sensor U2 are a, I1 ═ Ref1 ═ 5/R1 ═ a, and I2 ═ Ref2 ═ 5/R2 ×.a.

In step 32, if the DSP control chip U3 determines that I1 ≠ I2, I1 ═ Ref1, and I2 ═ Ref2 are not satisfied, it is determined that the first jack 11 and the second jack 12 are short-circuited, and the diode D2 flashes, thereby giving an alarm.

Let R1< R2, when I1 ═ I2 ═ 5/((R1 × R2)/(R1+ R2)) < Ref2< Ref 1. It is determined that the smart socket system has an abnormal conductor to short-circuit the first jack 11 and the second jack 12, and the diode D2 flickers according to the set rule, which is a simplified example shown in fig. 7. In this process, the maximum voltage of human body contact is 5V, so there is no safety problem.

Step 4, if the smart socket system detects that only the first jack 11 or the second jack 12 has a conductor to be accessed, it is determined that the smart socket system has another abnormal conductor to be accessed, the DSP control chip U3 will send different pulses to control the alarm lamp, such as the diode D2, to flash according to a certain length rule, and the flashing is performed for 2 times as a group and repeated continuously, where the flashing rule refers to the example shown in fig. 6.

Specifically, in the case where the first jack 11 is turned on, the diode D2 blinks long and short. With the second jack 12 conductive, the diode D2 blinks as soon as possible.

According to the scheme of the utility model, the automatic access recognition function is added, the alarm function is realized by inserting other abnormal conductors, and the interface is electrified and prompted. Under the abnormal condition, the strong current port of the system is not powered, so that the safety problems of electric shock caused by the mistaken touch of children, electric shock caused by the insertion of an abnormal conductor and the like can be effectively prevented.
