It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a block diagram of a charging control circuit of a single-hot switch according to a preferred embodiment of the present invention.
The preferred embodiment of the invention provides a charging control circuit of a single live wire switch, which comprises a power taking module 1, a charging module 2, an energy storage unit 3, a microprocessor 4 and a human body sensor 6, wherein the power taking module 1 is connected with the microprocessor 4 through the charging module 2 and the energy storage unit 3, and a live wire (L) forms a loop with a zero line (N) through the power taking module 1 and a load 5; the microprocessor 4 is connected with the power taking module 1; the microprocessor 4 is also connected to a body sensor 6.

For example, when it is determined that there is a person in the current environment, the microprocessor 4 may control the power generation module to turn off to stop charging the energy storage unit 3, so as to prevent the current flowing through the load from causing the load to flicker and being seen by the user during the charging process of the energy storage unit 3; when the current environment is judged to be nobody, the microprocessor 4 can control the power generation module to be switched on so as to start charging the energy storage unit 3. In this embodiment, the energy storage unit 3 is charged only when the current environment is nobody, that is, only when the current environment is nobody, the problem of load flicker caused by the current flowing through the load in the charging process of the energy storage unit 3 may occur, and because when nobody is present, the user cannot feel the flicker of the loads such as the bulb, the user can be effectively prevented from seeing the flicker of the load 5 caused by charging the energy storage unit 3 from the visitation, and the user experience is enhanced.

Because the available electricity taking module 1 charges the energy storage unit 3 when the load 5 is switched on or switched off, the battery does not need to be frequently replaced, and the operation is more convenient. Moreover, whether a person exists in the current environment can be judged through sampling information collected by the human body sensor 6, and the power-taking module 1 is controlled to be switched on or switched off according to a judgment result so as to control the charging of the energy storage unit 3, so that a user is prevented from seeing the flickering of the load 5 caused by the charging of the energy storage unit 3.
Specifically, referring to fig. 2, fig. 2 is a circuit diagram of a charge control circuit of a single hot switch according to a preferred embodiment of the invention.
The electricity taking module 1 comprises a parallel electricity taking circuit 11, a first switch circuit 12 and a serial electricity taking circuit 13, a live wire forms a loop with a zero line through the serial electricity taking circuit 13, the first switch circuit 12 and a load 5, the serial electricity taking circuit 13 is also connected with the charging module 2, and the first switch circuit 12 is also connected with the microprocessor 4; the live wire also forms a loop with the zero line through the parallel power taking circuit 11 and the load 5; the parallel electricity taking circuit 11 is also connected with the charging module 2; the microprocessor 4 controls the first switch circuit 12 to be conducted to enable the load 5 to be connected, and the serial power taking circuit 13 is used for charging the energy storage unit 3 when the load 5 is connected; the microprocessor 4 controls the first switch circuit 12 to be turned off to disconnect the load 5, and the parallel power taking circuit 11 is used for charging the energy storage unit 3 when the load 5 is disconnected. Specifically, when a user presses a key on a switch panel, the microprocessor 4 controls electronic switches such as a relay to be turned on or off, the electronic switches such as the relay are turned on, and the load 5 is turned off; conversely, the load 5 is switched on. The parallel power-taking circuit 11 is a power-taking circuit when the load 5 (such as a bulb) is disconnected, an electronic switch such as a relay is disconnected, and alternating current flows to the load 5 through the parallel power-taking circuit 11. The first switch circuit 12 and the serial power supply circuit 13 constitute a power supply circuit when the load 5 is connected, and an electronic switch such as a relay is connected, so that the alternating current flows to the load 5 through the serial power supply circuit 13 and the first switch circuit 12. The two parts of power taking circuits can be connected to the charging module 2, the energy storage unit 3 is charged through the charging module 2, the energy storage unit 3 supplies power to the microprocessor 4, the microprocessor 4 is continuously powered when the switch is turned on and turned off, and the microprocessor 4 can normally work in real time. In this embodiment, the energy storage unit 3 is an energy storage device with a long service life, and includes, but is not limited to, a lithium battery, a super capacitor, and the like.
The parallel power taking circuit 11 comprises an electronic switch circuit 111 and an AC-DC circuit 112, the electronic switch circuit 111 is connected with the AC-DC circuit 112, the electronic switch circuit 111 is connected with a load 5, the electronic switch circuit 111 is also connected with the microprocessor 4, and the AC-DC circuit 112 is connected with the charging module 2; the AC-DC circuit 112 is used to convert alternating current into direct current to charge the energy storage unit 3; when the microprocessor 4 detects that the current flowing through the load 5 is greater than the preset second current threshold, the electronic switch circuit 111 is controlled to be turned off so as to directly turn off the parallel power-taking circuit 11. In this embodiment, the electronic switch circuit 111 may be implemented by an MOS transistor, a triode, or the like, the electronic switch circuit 111 is connected to a microprocessor 4(MCU), and the microprocessor 4 controls on/off of the electronic switch circuit 111. The AC-DC circuit 112 may be implemented using an AC-DC power chip.
When the load 5 is in an open state and the electronic switch circuit 111 inside the parallel power-taking circuit 11 is closed, the energy storage unit 3 is charged. Meanwhile, when the parallel power-taking circuit 11 works, current flows through the load 5, and a problem of micro-flash of the load (such as a lamp) when the load is turned off may occur. In this embodiment, a human body sensor 6 is further provided to solve this problem, and the human body sensor 6 includes, but is not limited to, an infrared sensor and the like. The human body sensor 6 is connected with the microprocessor 4, and the human body sensor 6 is used for providing sampling information for the microprocessor 4 so that the microprocessor 4 can judge whether a person exists in the current environment. For example, the motion sensor 6 is normally in a sleep state, and when a person is present in the detection range, the motion sensor 6 transmits the sampling information to the microprocessor 4. If no people are detected within the preset time (for example, 2 hours), the microprocessor 4 judges that the current environment is unmanned, and the microprocessor 4 controls the electronic switch circuit 111 to be switched on when judging that the current environment is unmanned, so that the parallel power taking circuit 11 can charge the energy storage unit 3 through the charging module 2, and the electric quantity of the energy storage unit 3 can be ensured to normally work for the microprocessor 4. In the embodiment, the parallel power taking circuit 11 is controlled to be turned on to charge the energy storage unit only when no person exists in the current environment, so that even if the load slightly flashes due to the fact that current passes through the load in the charging process, a user cannot feel the micro-flashes of the loads such as the lamp bulb and the like in the current unmanned environment, and therefore user experience is enhanced visually.
After the microprocessor 4 receives the sampling information of whether a person exists in the sensing range acquired by the human body sensor 6, the sampling information can be analyzed and processed. For example, in an alternative embodiment, the microprocessor 4 determines whether the current environment is occupied according to the sampling information, and stores the determination result in association with the acquisition time of the sampling information. And the microprocessor 4 carries out analysis and calculation according to the judgment result and the associated data of the acquisition time of the sampling information to obtain a manned time range corresponding to the judgment result of the manned environment and an unmanned time range corresponding to the judgment result of the unmanned environment. When the current time is within the unmanned time range, the microprocessor 4 controls the power taking module 2 to be switched on so as to charge the energy storage unit 3 when no person exists in the current environment. That is, the time range corresponding to the home of the user and the time range not corresponding to the home of the user are determined, and the time range in which no one is at home is used as the basis for controlling the parallel power-taking circuit 11 to be turned on.
In another alternative embodiment, the microprocessor 4 determines whether the current environment is occupied according to the sampling information, and performs combined analysis on the determination result and the user behavior to further determine whether the user is at home. If the judgment result shows that the current environment is unmanned but the load starting behavior of the user is detected, the analysis user is at home, the power taking module 1 is controlled to be turned off, and the charging of the energy storage unit is disconnected, so that the situation that the load flickers when the user is at home is prevented. For example, if it is determined that there is no person in the current environment according to the sampling information detected by the human body sensor 6, but a behavior of turning on a light of the user is detected, the parallel power taking circuit 11 is controlled to be turned off when the user is at home or at home, so as to prevent the load from flickering when the user is at home, and enhance the user experience.
Further, the human body sensor 6 can be arranged inside or outside the single live wire switch, when the human body sensor 6 is arranged inside the single live wire switch, the microprocessor 4 can judge whether the current environment is occupied or not according to the sampling information after receiving the sampling information, the microprocessor 4 can also send the sampling information to the intelligent gateway after receiving the sampling information, and the intelligent gateway judges whether the current environment is occupied or not according to the sampling information and then sends the judgment result to the microprocessor 4. Or the intelligent gateway uploads the sampling information to the cloud server, and the cloud server judges whether the current environment is occupied or not according to the sampling information and then sequentially sends the judgment result to the intelligent gateway and the microprocessor 4.
When the calculation judgment process is carried out in the intelligent gateway or the cloud server, in an optional implementation mode, more than one single live wire switch possibly exists in a user house, the detection range of the human body sensor in each single live wire switch is limited, the sampling information detected by the human body sensor in each single live wire switch can be sent to the intelligent gateway, if the current environment is judged to be someone by the intelligent gateway according to the sampling information sent by the human body sensor in at least one single live wire switch, the judgment result that the current environment is someone is sent to all the single live wire switches.
When the human body sensor 6 is arranged outside the single live wire switch, the single live wire switch and the human body sensor 6 are respectively connected with the intelligent gateway to form a local area network. And the sampling information acquired by the human body sensor 6 is sent to the intelligent gateway. In an implementation manner, the intelligent gateway may determine whether there is a person in the current environment according to the received sampling information, and issue the determination result to the single fire wire switch after obtaining the determination result. In another embodiment, the intelligent gateway can also directly send the received sampling information to the single live wire switch, and the microprocessor 4 in the single live wire switch judges whether the current environment is occupied according to the sampling information and controls the power taking module to be switched on and off according to the judgment result so as to control the charging of the energy storage unit.
Further, in a normal state, when a user turns on the lamp, the serial power taking circuit 13 is used for taking power, and the energy storage unit 3 is charged through the charging module 2. When the user turns off the lamp, if the energy storage unit 3 has sufficient power, the energy storage unit 3 does not need to be charged through the parallel power taking circuit 11. In an embodiment, the microprocessor 4 is further configured to detect an electric quantity of the energy storage unit 3 when the load 5 is turned off, and when the electric quantity of the energy storage unit 3 is detected to be lower than a preset electric quantity threshold value and it is determined that no person, i.e., a user, is present in the current environment according to the sampling information, the electronic switch circuit 111 is controlled to be turned on to control the parallel power taking circuit 11 to be turned on and charge the energy storage unit 3, so that the energy storage unit 3 can normally supply power to the microprocessor 4, and the microprocessor 4 can normally operate.
As shown in fig. 3, fig. 3 is a schematic flowchart of a charging control method for a single live wire switch according to an embodiment of the present invention, where the charging control method for the single live wire switch includes the following steps:
step S10, the power taking module takes power when the load is switched on or off and charges the energy storage unit through the charging module;

and step S40, the microprocessor receives the sampling information, judges whether the current environment is occupied or not according to the sampling information, and controls the power taking module to be switched on or off according to the judgment result so as to control the charging of the energy storage unit.

Because the energy storage unit can be charged by the power taking module when the load is switched on or switched off, the battery does not need to be frequently replaced, and the power taking module is more convenient. And whether the current environment is occupied or not can be judged through sampling information collected by the human body sensor, and the power taking module is controlled to be switched on or switched off according to a judgment result so as to control the charging of the energy storage unit, so that a user is prevented from seeing load flicker caused by the charging of the energy storage unit.
In an optional embodiment, on the basis of the above embodiment, the method further includes:
and the microprocessor judges whether the current environment is occupied or not according to the sampling information and stores the judgment result and the acquisition time of the sampling information in a correlation manner. And the microprocessor analyzes and calculates according to the judgment result and the associated data of the acquisition time of the sampling information to obtain a manned time range corresponding to the judgment result of the manned environment in the current environment and an unmanned time range corresponding to the judgment result of the unmanned environment in the current environment. When the current time is within the unmanned time range, the microprocessor controls the power taking module to be switched on so as to charge the energy storage unit when no person exists in the current environment. The time range corresponding to the home of the user and the time range corresponding to the absence of the user are judged, and the time range of the absence of the user at home is used as the basis for controlling the parallel power taking circuit to be opened.
In an optional embodiment, on the basis of the above embodiment, the method further includes:
and the microprocessor judges whether the current environment is occupied or not according to the sampling information, and performs combined analysis on the judgment result and the user behavior so as to further judge whether the user is at home or not. If the judgment result shows that the current environment is unmanned but the load starting behavior of the user is detected, the analysis user is at home, the power taking module is controlled to be turned off, and the charging of the energy storage unit is disconnected, so that the situation that the load flickers when the user is at home is prevented. For example, if it is determined that the current environment is unmanned according to sampling information detected by a human body sensor, but a behavior of turning on a light of a user is detected, the user is finally analyzed to be at home, and the parallel power taking circuit is controlled to be turned off under the condition that the user is at home, so that the situation that the load flickers when the user is at home is prevented, and user experience is enhanced.
