Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent switches, and in particular to a multi-control intelligent switch. Background Art

[0002] When the current smart switch replaces the ordinary switch, a relatively simple single-control replacement can be achieved. For the dual-control solution in which two smart switches (here two smart switches are taken as an example) control an electrical device together, it is very difficult to replace both. The key problem is that the state of the smart switch is uncertain during the initial installation, and it is difficult to draw power when connected to the dual-control circuit.

[0003] Specifically, the smart switch usually includes a controller and an electronic switch. During the normal use stage after the configuration is completed, the on and off of the electronic switch can be controlled by the controller. However, during the initial installation stage when the controller has not yet been configured, the power supply circuit is required to power the controller to complete the network configuration. Since the two smart switches are connected in series in the control loop of the electrical equipment, when the two smart switches are turned on or off at the same time, the impedance of the control circuit where the two smart switches are located is equal, and the respective power supply circuits can obtain electrical energy to power the controllers of their respective control circuits; when one smart switch is turned on and the other smart switch is turned off, it is difficult for the power supply circuit of the closed smart switch to obtain current and cannot power the corresponding controller, and the controller cannot complete the network configuration.

[0004] Since the initial state of the smart switch received by the user is unknown, there is a high probability that the smart switch will be turned on and off, causing network configuration failure. Utility Model Content

[0024] The embodiment of the present disclosure provides a multi-control intelligent switch. The preferred embodiment of the present disclosure is described below in conjunction with the drawings of the specification. It should be understood that the preferred embodiment described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.

[0025] The present disclosure provides a multi-control intelligent switch. Figure 1 As shown, it includes: at least two intelligent switch circuits 10 are arranged in series between two connection terminals L and L1; wherein each intelligent switch circuit 10 includes: a controller 101, an electric control switch 102, a configuration switch 103, and a power supply module 104 connected in parallel with the electric control switch 102 for supplying power to the controller 101;

[0026] The configuration switch 103 is used to respond to the first external operation instruction in the network configuration stage to make the intelligent switch circuit 10 connected;

[0027] The controller 101 is used to send an electric control signal to the electric control switch 102 through a pin after completing the network configuration;

[0028] The electric control switch 102 is used to control the connection or disconnection of the intelligent switch circuit when receiving an electric control signal.

[0029] The embodiments of the present disclosure can be applied to a single live wire scenario. In one implementation, terminal L1 can be connected to the live wire, and terminal L can be connected to an electrical device (or terminal L is connected to the live wire, and terminal L1 is connected to an electrical device, which is not limited here).

[0030] Figure 2 This is a schematic diagram of the structure of a dual-control intelligent switch in an ordinary switch. Figure 2 As shown, taking two groups of intelligent switch circuits as an example, for each group of intelligent switch circuits, the power supply module 104 is approximately connected in parallel with the electric control switch 102 (here implemented as a single-pole switch relay). In ordinary switches, the connection of the two terminals L and L1 is for the use of electrical equipment, and after replacing with an intelligent switch, the power supply problem of the controller 101 needs to be considered, especially the case of a single live wire. Therefore, in the related art, different circuits are designed for the controller 101 to obtain power, and the power supply module 104 is approximately connected in parallel with the electric control switch 102. Furthermore, since at least two intelligent switch circuits 10 are connected in series between L and L1, when the electric switches 102 of at least two intelligent switch circuits 10 are simultaneously turned on or off, the impedances of the two intelligent switch circuits are equal, and their respective power supply modules 104 (control loop power supply) can obtain electrical energy to power their respective corresponding controllers 101; and when some of the electric switches 102 in different intelligent switch circuits 10 are turned on and some of the electric switches 102 are turned off, since the electric switch 102 has a smaller impedance than the power supply module 104, it is difficult for the power supply module 104 of the closed electric switch 102 to obtain current and cannot power the corresponding controller 101. In the network configuration stage, if the controller 101 cannot be used for control, the network configuration cannot be completed.

[0031] The embodiment of the present disclosure provides a configuration switch 103, and the electric control switch 102 and the configuration switch 103 can be connected in series between two terminals L and L1. By designing the structures of the electric control switch 102 and the configuration switch 103, by operating the configuration switch 103 (i.e., receiving the first external operation instruction), no matter whether the current state of the electric control switch 102 is closed or open, the intelligent switch circuit where it is located can be connected. When at least two intelligent switch circuits are connected, the terminals L and L1 are connected, the impedances of at least two intelligent switch circuits are equal, and the respective power supply modules 104 (control loop power supply) can obtain electrical energy to power the corresponding controllers 101 to complete the network configuration.

[0032] In addition, the number of multiple groups of intelligent switch circuits between L and L1 can be set as needed. Figure 1 In the example, two sets of intelligent switch circuits are set. The electric switch 102 is connected to the pin of the controller 101 (directly or indirectly) to control the electric switch 102. The electric switch 102 can be a switch that can be turned on or off according to the control signal sent by the controller 101, such as a relay.

[0033] In another embodiment provided by the present disclosure, Figure 3 As shown, the electric control switch 102 includes a single-pole double-throw electronic switch 1021, and the single-pole double-throw electronic switch 1021 is provided with a movable end K, a first fixed end A and a second fixed end B; the configuration switch 103 includes a single-pole single-throw mechanical switch 1031;

[0034] The moving end K and the first fixed end A are respectively located between the two connection terminals; the second fixed end B is connected to one end of the single-pole single-throw mechanical switch 1031; and the other end of the single-pole single-throw mechanical switch 1031 is connected to the first fixed end A.

[0035] In the embodiment of the present disclosure, two paths can be designed for the electric control switch 102, one path directly connects the intelligent switch circuit, and the other path connects the intelligent switch circuit by adding a manually controlled mechanical switch (configuration switch 103). In this way, no matter which path the electric control switch 102 is in at the beginning, the intelligent switch circuit can be controlled to be connected by manual control.

[0036] In a possible implementation, the electronically controlled switch 102 may be implemented as a single-pole double-throw electronic switch 1021, and the configuration switch 103 may be implemented as a single-pole single-throw switch 1031. When the moving end K of the single-pole double-throw electronic switch 1021 is connected to the fixed end A of the single-pole double-throw electronic switch 1021, the intelligent switch circuit where the single-pole double-throw electronic switch 1021 is located is connected. When the moving end K of the single-pole double-throw electronic switch 1021 is connected to the fixed end B of the single-pole double-throw electronic switch 1021, the single-pole double-throw electronic switch 1021 connects the intelligent switch circuit where it is located through the single-pole single-throw mechanical switch 1031. That is, when the single-pole single-throw mechanical switch 1031 is closed, the intelligent switch circuit where it is located is connected, and when the single-pole single-throw mechanical switch 1031 is opened, the intelligent switch circuit where it is located is disconnected. It can be seen that as long as the single-pole single-throw mechanical switch 1031 is in a closed state, no matter the moving end K of the single-pole double-throw electronic switch 1021 is connected to the fixed end A or the fixed end B, the intelligent switch circuit can be connected. If at least two intelligent switch circuits are connected, the two connection terminals can be connected.

[0037] In this way, during the network configuration stage of the intelligent switch, as long as the single-pole single-throw mechanical switches 1031 of at least two intelligent switch circuits are in a closed state, the impedance of at least two intelligent switch circuits can be ensured to be equal, and the respective power supply modules 104 (control loop power supply) can obtain electrical energy to power the corresponding controllers 101 to complete the network configuration.

[0038] In yet another embodiment provided by the present disclosure, the intelligent switch further includes a switch button;

[0039] The switch button is connected to the configuration switch 103 and is used to receive a first external operation instruction from a user during the network configuration phase to place the configuration switch 103 in a closed state.

[0040] In the embodiment of the present disclosure, in order to ensure that the single-pole single-throw mechanical switches 1031 of at least two intelligent switch circuits are in a closed state, a switch button can be set for the configuration switch 103. The user can issue a first external operation instruction by operating the switch button to close the configuration switch, thereby starting the configuration process.

[0041] During implementation, the switch button may be a push button, a twist button, a toggle button, etc., and there is no limitation on the operation method of the switch button.

[0042] In another embodiment provided by the present disclosure, the switch button is further used to receive a second external operation instruction from the user after the network configuration is completed, so as to place the configuration switch 103 in an off state.

[0043] In the embodiment of the present disclosure, after the configuration is completed, in order not to affect the normal operation of the subsequent electric control switch 102, a second external operation instruction can be issued by operating the switch button to disconnect the configuration switch 103.

[0044] In another embodiment provided in the present disclosure, the electric control switch 102 is used to control the dynamic terminal K to be connected to the first static terminal A when receiving an electric control signal for controlling the connection of the intelligent switch circuit; and to control the dynamic terminal K to be connected to the second static terminal B when receiving an electric control signal for controlling the disconnection of the intelligent switch circuit.

[0045] In the embodiment of the present disclosure, after the configuration is completed, during the normal use of the intelligent switch, when the multi-control intelligent switch is configured so that each intelligent switch is controlled separately, for each intelligent switch, the electric control switch 102 can control the connection or disconnection of the intelligent switch circuit when receiving the electric control signal, that is, when the received electric control signal indicates that the intelligent switch circuit is controlled to be connected, the moving end K is controlled to be connected to the first fixed end A;

[0046] When the received electric control signal indicates that the intelligent switch circuit is disconnected, the movable terminal K is controlled to be connected to the second fixed terminal B. Since the configuration switch 103 is in the disconnected state through the second external operation instruction after the network configuration is completed, even if the movable terminal K is connected to the second fixed terminal B, the intelligent switch circuit cannot be connected.

[0047] In another embodiment provided by the present disclosure, the electric control switch 102 is used to control the movable terminal K to be connected to the first fixed terminal A or the second fixed terminal B when receiving an electric control signal for controlling the connection or disconnection of the intelligent switch circuit when the intelligent switch circuit is configured as a main control circuit;

[0048] When the intelligent switch circuit is configured as an auxiliary circuit, the movable terminal K is controlled to be connected to the first fixed terminal A.

[0049] In the embodiment of the present disclosure, after the configuration is completed, during the normal use of the intelligent switch, when the multi-control intelligent switch is configured as a main control circuit and an auxiliary circuit, the intelligent switch as the auxiliary circuit can be set to a connected state all the time, that is, the active terminal K in the intelligent switch circuit as the auxiliary circuit is always connected to the first fixed terminal A. The intelligent switch as the main control circuit can respond to the electric control signal, for example: when receiving the electric control signal to control the connection of the intelligent switch circuit, the active terminal K is controlled to be connected to the first fixed terminal A, and when receiving the electric control signal to control the disconnection of the intelligent switch circuit, the active terminal K is controlled to be connected to the second fixed terminal B.

[0050] In another embodiment provided by the present disclosure, after the network configuration is completed, the switch button is encapsulated in the physical device where the multi-control intelligent switch is located.

[0051] In the embodiment of the present disclosure, since the configuration switch 103 is used in the network configuration stage, the subsequent normal use stage of the smart switch can be in a disconnected state. Therefore, the corresponding configuration operation can be performed in the network configuration stage. In order not to affect the subsequent use, the switch button can be encapsulated in the physical device where the smart switch is located after the configuration is completed. For example, if the physical device of the smart switch is a wall switch, the switch button can be encapsulated in the wall switch.

[0052] In yet another embodiment provided by the present disclosure, the single-pole double-throw electronic switch includes a single-pole double-throw relay.

[0053] In another embodiment provided by the present disclosure, one of the two terminals is connected to the live wire, and the other terminal is connected to the electrical device.

[0054] In another embodiment provided by the present disclosure, the power supply module 104 includes: a first power supply module and / or a second power supply module;

[0055] A first power supply module, used to supply power to the controller 101 when the electrical equipment is operating normally;

[0056] The second power supply module is used to supply power to the controller 101 when the power-consuming device stops working.

[0057] In the embodiments of the present disclosure, the implementation of the first power supply module can refer to the relevant technology. For example, the first power supply module is implemented by using the typical application of the BP8005 chip, which will not be described in detail here. The second power supply module can obtain the electrical energy in the circuit to power the controller 101 when the electrical equipment stops working. When implemented, it can be implemented through a serially connected bridge circuit and AC / DC (Alternang Current / Direct Current), which will not be described in detail here. In addition, the first power supply module and the second power supply module can power the controller 101 through different pins of the controller 101, or through the same pins, which is not limited here.

[0058] A multi-control smart switch provided by an embodiment of the present disclosure has a configuration switch set in each smart switch circuit. In the network configuration stage, according to a first external operation instruction, the smart switch circuit is connected, and when multiple smart switches are connected, the two wiring terminals are connected. In this way, no matter what the initial state of the smart switch obtained by the user is, the configuration switch can be used to achieve the connected state of the smart switch, and each smart switch circuit can obtain electrical energy to power the corresponding controller, thereby improving the success rate of network configuration.
