Taking the intelligent socket as an example, the size of the intelligent socket is small, after the intelligent socket is connected with a high-power electric appliance, the heating effect of the high-power electric appliance is superposed with the heating effect of the communication module, and the average non-fault time of the high-power electric appliance during operation is reduced in the past; relays used for high-power control in smart sockets (for example, relays of 10A and 16A) are sensitive to level changes of control pins, and an uncertain working state can occur, which causes accidental power failure of connected external electrical equipment and influences stability.
In view of this, the present application provides an electrical device based on wireless control to realize the stability of the operation of the electrical device and reduce the heat generation amount.

wherein the content of the first and second substances,
the communication module has two states:
one is a working state, which is a full power operation mode, and is generally used for acquiring connection information of the wireless router and reporting the current working state to an application program (APP) of the user terminal when the wireless router is initially powered on, and the duration is generally several minutes;
the other is a non-working state, including one of dormancy, crash, restart, and wakeup, wherein, for the smart socket, because there is no complex operation function, the dormancy state usually lasts for a long time, the state is a low power consumption operation mode, and the operation frequency of the communication module is reduced, for example, the transmission power and/or frequency of the wireless signal and the network scanning frequency are reduced, so as to silence the wireless signal, thereby reducing the wireless interference generated by the communication module to other communication modules; the receiving frequency of the wireless signals is reduced so as to reduce the wireless interference probability of other communication modules to the communication module; thus, the heat generation amount is favorably reduced in the sleep state.
Under the condition that a large number of intelligent sockets are installed, each intelligent socket is in a low-power-consumption operation mode, the load of the whole wireless network is reduced, and the whole operation quality is improved.

as an example of the manner in which the device may be used,

as another example, the current device state of the switch circuit in the relay module of the smart socket may also be obtained and stored; or, determining the equipment state according to the current control command; the current equipment state of the switch circuit in the relay module can be used for locking the control signal by the communication module through the stabilizing module in the non-working state, and the current equipment state can be stored in the communication module and also can be stored in the stabilizing module.

The stabilizing module is connected between the communication module and the relay module, a control signal output end of the communication module is connected with an input end of the stabilizing module, an output end of the stabilizing module is connected with a control end of the relay module, the control signal is kept to be a set voltage value and is supplied to the control end of the relay module according to the current state of a switch circuit in the relay module when the communication module is in a non-working state until a next control command is responded, and the control signal is supplied to the control end of the relay module when the communication module is in a working state. And a switch circuit in the relay module is connected to an output port of the power supply.
In one embodiment:
the communication module responds to a first control command from a user terminal in an operating state to generate a first control signal with a non-transient voltage value, and in a non-operating state, generates a second control signal with a transient voltage value, wherein the transient voltage value is as follows: except for voltage values other than the transient voltage values.
Referring to fig. 4, fig. 4 is a schematic view of a stabilizing module according to an embodiment of the present disclosure. Stabilize the module and include:
and the holding circuit is used for latching the current signal so as to hold the current signal as a set voltage value.
One of the following circuits may also be included:
a first isolation circuit for isolating an interference signal from a wireless network side,
a second isolation circuit for isolating an interference signal from the power supply side,
wherein the content of the first and second substances,
the first isolation circuit is connected between the control signal output end of the communication module and the input end of the holding circuit,
the second isolation circuit is connected between the output end of the holding circuit and the control end of the relay module.
The first isolation circuit receives a first control signal (at this time, the communication module is in an operating state) from the communication module, for example, the control signal 1 corresponding to an open socket command is a high level signal, i.e., a first voltage value, the control signal 0 corresponding to a close socket command is a low level signal, i.e., a second voltage value, wherein the first voltage value and the second voltage value are both non-transient voltage values, and then the voltage values except the first voltage value and the second voltage value are both transient voltage values.
The holding circuit is used for holding the set voltage value of the current control signal, and specifically comprises the following steps:
when the communication module is in working state, the first control signal is input to the input terminal of the holding circuit through the first isolation circuit, the holding circuit outputs the first control signal,
when the communication module is in a non-working state such as a sleep state or a restart process, since the control command is not directly responded, the control signal of the communication module is a transient voltage value except for the first voltage value and the second voltage value, which is called a second control signal for convenience of the art, at this time, the holding circuit latches the second control signal as a set voltage value determined by the first control signal, for example, the same voltage value as the first control signal.
For example, when the communication module is in an operating state, a high level (a first voltage value) of the control signal 1 is input to an input terminal of the holding circuit, and the holding circuit outputs a first set voltage value, which turns on a switch circuit in the relay module to output the power supply; if the communication module enters a non-working state such as a dormant state or a restarting process, the holding circuit still maintains the current first set voltage value although the control signal of the communication module is a transient voltage value, so that the switching circuit is kept on, and the power supply is continuously output until the communication module responds to a next control command to generate a next control signal.
Similarly, when the communication module is in the working state, and the low level (second voltage value) of the control signal 0 is input to the input end of the holding circuit, the holding circuit outputs a second set voltage value, and the second set voltage value enables the switch circuit in the relay module to be turned off so as to disconnect the output of the power supply; if the communication module is in a non-working state such as a dormant state or a restarting process, the holding circuit still holds the current second set voltage value although the control signal of the communication module is the transient voltage value, so that the switching circuit is kept off, and the output of the power supply is disconnected until the communication module generates the next control signal in response to the next control command.
Therefore, no matter what interference is received by the control signal from the communication module or what transient voltage value is obtained, the corresponding set voltage value can be kept for the transient voltage value through the holding circuit, so that the heat effect of the communication module is reduced, and the stability and the reliability of the intelligent socket are improved.
The holding circuit can be built by using MOS (metal oxide semiconductor) tubes and RC (resistor-capacitor) separation devices as auxiliary devices, or can be built by using a special latch integrated chip, and the core function of the holding circuit is to receive a voltage signal, latch the signal until receiving another voltage signal, and then change the value of the latch signal according to the received another voltage signal.
Referring to fig. 5, fig. 5 is a timing diagram of the hold circuit. In the figure, u1 represents a control signal from the communication module, i.e. an input signal of the stabilization module; u2 represents the output signal of the holding circuit, the signal with the first voltage value is the control signal 1, the signal with the second voltage value is the control signal 0, except that the signal with the first voltage value and the signal with the second voltage value are the transient voltage part, at the output end of the holding circuit, the setting voltages corresponding to the control signal 1 and the control signal 0 are the first setting voltage value and the second setting voltage value respectively, the setting voltage corresponding to the transient voltage part is the current setting voltage, that is, when the current voltage is the first setting voltage value, the setting voltage corresponding to the transient voltage part is the first setting voltage, and when the current voltage is the second setting voltage value, the setting voltage corresponding to the transient voltage part is the second setting voltage.
In another embodiment:
the communication module responds to the first control command in a working state, generates a first control signal with a non-transient voltage value, acquires a current equipment state under the control of the first control signal, and stores the current equipment state; reading the stored current device state in a non-operating state, outputting a third control signal for maintaining the current device state according to the current device state,
the stabilizing module outputs a set voltage value corresponding to the current control signal according to the current control signal.
For example, when the communication module is in a working state, a high level of the control signal 1 is input to an input end of the stabilization module, the stabilization module outputs a first set voltage value, the first set voltage value enables a switch circuit in the relay module to be switched on to output a power supply, the communication module acquires a current equipment state of the intelligent equipment, and stores the current equipment state in the communication module or the stabilization module, wherein the current equipment state is a conducting state; if the communication module enters a non-working state such as a dormant state or a restarting process, the communication module reads the current equipment state, and outputs a third control signal for maintaining the current equipment state according to the current equipment state, for example, a control signal with a first voltage value, and the control signal enables the stabilizing module to output a first set voltage value; therefore, even if the communication module is in a non-working state such as dormancy, crash, restart and the like, the stabilizing module can still keep the first set voltage value, so that the switching circuit is kept conducted, and the power supply is continuously output.
Similarly, when the communication module is in a working state, the low level of the control signal 0 is input to the input end of the stabilization module, the stabilization module outputs a second set voltage value, the second set voltage value enables the switch circuit in the relay module to be turned off so as to cut off the output of the power supply, the communication module acquires the current equipment state of the intelligent equipment, and stores the current equipment state in the communication module or the stabilization module, wherein the current equipment state is the off state; if the communication module enters a non-working state such as a dormant state or a restarting process, the communication module reads the current equipment state, and outputs a third control signal for maintaining the current equipment state according to the current equipment state, for example, a control signal with a second voltage value, and the control signal enables the stabilizing module to output a second set voltage value; thus, even if the communication module is in a non-working state such as dormancy, crash, restart, etc., the stabilizing module can still keep the second set voltage value, thereby keeping the switch circuit off and disconnecting the output of the power supply.
The stabilizing module may be the same as in fig. 4.
Referring to fig. 6, fig. 6 is a timing diagram of a stabilization module according to an embodiment of the disclosure. In the figure, u1 represents a control signal from the communication module, i.e., an input signal of the stabilization module, u2 represents an output signal of the stabilization module, a signal having a first voltage value is a control signal 1, a signal having a second voltage value is a control signal 0, and in addition to the control signal 1 and the control signal 0, there are control signals for maintaining the current device state; at the output end of the stabilizing module, the setting voltages corresponding to the control signal 1 and the control signal 0 are respectively a first setting voltage value and a second setting voltage value, and the setting voltage corresponding to the control signal for maintaining the current device state is the current setting voltage, that is, when the current voltage is the first setting voltage value, the setting voltage corresponding to the control signal for maintaining the current device state is the first setting voltage, and when the current voltage is the second setting voltage value, the setting voltage corresponding to the control signal for maintaining the current device state is the second setting voltage.
In yet another embodiment:
the communication module responds to the first control command in a working state to generate the control signal, acquires the current equipment state under the control of the control signal, stores the current equipment state, suspends the output of the control signal in a non-working state,
the stabilizing module outputs a set voltage value corresponding to the control signal under the condition that the control signal exists, reads the current equipment state under the condition that the control signal does not exist, and outputs the set voltage value for maintaining the current equipment state according to the current equipment state, wherein the set voltage value is determined by the control signal.
For example, when the communication module is in a working state, a high level of the control signal 1 is input to an input end of the stabilization module, the stabilization module outputs a first set voltage value, the first set voltage value enables a switch circuit in the relay module to be switched on to output a power supply, the communication module acquires a current equipment state of the intelligent equipment, and stores the current equipment state in the communication module or the stabilization module, wherein the current equipment state is a conducting state; if the communication module enters a non-working state such as a dormant state or a restarting process, the stabilizing module reads the current equipment state, and keeps the first set voltage value and outputs the first set voltage value according to the current equipment state, so that the stabilizing module can still keep the first set voltage value even if the communication module is in the non-working state such as the dormant state, the dead halt state, the restarting state and the like, and the switching circuit is kept on to continuously output the power supply.
Similarly, when the communication module is in a working state, the low level of the control signal 0 is input to the input end of the stabilization module, the stabilization module outputs a second set voltage value, the second set voltage value enables the switch circuit in the relay module to be turned off so as to cut off the output of the power supply, the communication module acquires the current equipment state of the intelligent equipment, and stores the current equipment state in the communication module or the stabilization module, wherein the current equipment state is the off state; if the communication module enters a non-working state such as a dormant state or a restarting process, the stabilizing module reads the current equipment state, and keeps the second set voltage value and outputs the second set voltage value according to the current equipment state, so that even if the communication module is in the non-working state such as the dormant state, the dead halt state, the restarting state and the like, the stabilizing module can still keep the second set voltage value, thereby keeping the switch circuit off and disconnecting the output of the power supply.
