Description

Technical Field

[0001] The present invention relates to the field of wireless control, and in particular to a self-powered control system, a wireless controller, and a wireless connection method and a control method. Background Art

[0002] The wireless switch with self-powered function does not need to be connected to the circuit through a cable or built-in battery, but converts mechanical energy into electrical energy by pressing the switch to power the communication module inside the wireless switch. Therefore, the self-powered wireless switch is widely used in the switch control of electrical appliances because of its energy saving and environmental protection.

[0003] The energy generated by the existing self-powered wireless switch is extremely limited, and it can only transmit codes in a very short time, and it itself has no ability to receive and process signals. Therefore, the existing self-powered wireless switch cannot directly access wireless networks such as Bluetooth MESH networks or ZIGBEE networks.

[0004] In the existing Bluetooth MESH communication protocol, it is necessary to write a triplet in the Bluetooth device, that is, it is necessary to burn the three elements of MAC (address), PID (user information), and key (encrypted information) in the Bluetooth storage chip. The Bluetooth device of the prior art needs about 12 seconds of communication time to complete the wireless configuration during the initial configuration with the MESH network. In addition, after the initial configuration of the Bluetooth terminal device and the MESH network is successful, for the security of the network, the MESH network will also communicate with the Bluetooth terminal device regularly (for example, every 48 hours), and regularly update the key stored in the Bluetooth terminal device to improve the security of the MESH network. Therefore, the Bluetooth terminal device must have the ability to continuously receive signals, and the existing self-powered wireless control device cannot have such a function. That is to say, the self-powered wireless switch of the prior art can only control the switch of the electrical appliance through the wireless control device, but cannot connect to the wireless network, and control other electrical equipment through the wireless network. The energy generated by the self-powered wireless switch device of the prior art is only enough to transmit a signal of tens of milliseconds for the communication circuit, and such a short communication time cannot be directly connected to the wireless network.

[0005] The Chinese invention patent with application number 201880001098.9 discloses a circuit control system and a series control device and a control method thereof, wherein the circuit control system includes a mobile control device and a series control device, wherein the series control device is connected in series to the live wire of the circuit and obtains electrical energy from the live wire. The mobile control device sends a control signal to the series control device in a self-powered manner, wherein the series control device receives the control signal of the mobile control device and controls the operation of the load electrical appliance. The control method in this invention patent only solves the problem of connecting the self-powered switch to the single live wire switch, and does not involve how to solve how the self-powered switch can be connected to the wireless network.

[0006] The operating current of the series self-powered control device in the prior art is too low to support the operation of two or more wireless communication modules, nor can it support the operation of dual-mode communication modules. As the number of communication modules increases, the power consumption of the self-powered control device will increase, which will cause abnormal flickering of electrical equipment in the series circuit, such as lamps, when not in operation, affecting the normal service life of the electrical equipment.

[0151] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0152] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0153] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0154] Referring to the accompanying drawings of the present invention Figures 1 to 4 As shown, a self-powered control system according to the first preferred embodiment of the present invention is explained in the following description. The self-powered control system includes a self-powered switch 10 and at least one wireless controller 20, wherein the wireless controller 20 is connected to a circuit 100 and controls the current working state of at least one electrical device 200 in the circuit 100. The self-powered switch 10 is communicatively connected to the wireless controller 20, and the self-powered switch 10 generates and transmits a control information to the wireless controller 20 in a self-powered manner, wherein the wireless controller 20 controls the working state of the electrical device 200 in the circuit 100 based on the control information. The wireless controller 20 can be connected to a wireless device 300, wherein the wireless controller 20 can receive a control signal sent by the wireless device 300, and the wireless controller 20 controls the working state of the electrical device 200 in the circuit 100 based on the control signal. The wireless controller 20 transmits the action result information of the electrical device 200 to the wireless device 300 in a wireless transmission manner.

[0155] The wireless controller 20 can transfer the control information of the self-powered switch 10 to the wireless device 300 , and connect the self-powered switch 10 to the wireless device 300 through the wireless controller 20 , so that the self-powered switch 10 controls other electrical devices in the wireless device 300 through the wireless controller 20 .

[0156] Preferably, the wireless device 300 can be, but is not limited to, a MESH network, wherein the wireless controller 20 obtains control instructions transmitted by the MESH network, and transmits the control signal generated by the self-powered switch 10 and the circuit control information of the electrical device 200 in the circuit 100 to the MESH network, so that the MESH network can know the control state of the electrical device 200, or control other electrical devices of the MESH network based on the control instructions of the self-powered switch 10, such as the switching of lamps and the opening and closing of curtains. It is understandable that the wireless device 300 can also be implemented as other types of wireless devices, such as a wireless local area network. Therefore, in this preferred embodiment of the present invention, the specific implementation of the wireless device 300 is not limited here.

[0157] like Figure 2AAs shown, the self-powered switch 10 wirelessly sends a control signal in a self-powered manner, wherein the wireless controller 20 receives the control signal, executes a control instruction to control the electrical device 200 based on the content of the control signal, and / or transmits the control signal to the wireless device 300. In other words, the wireless controller 20 has the ability to receive the self-powered switch 10 signal and the wireless device 300 signal. In the first preferred embodiment of the present invention, the wireless controller 20 is connected to the circuit 100 in series, and the circuit 100 provides the working current of the wireless controller 20 to keep the wireless controller 20 receiving the control signal and performing the control operation.

[0158] It is worth mentioning that the circuit 100 can be but not limited to a two-phase circuit, and the circuit 100 includes a live wire 110 and a neutral wire 120, wherein the wireless controller 20 is connected in series to the live wire 110 of the circuit 100. It is understandable that the wireless controller 20 can also be connected to a live wire in a three-phase circuit, and any live wire of the three-phase circuit 20 provides working power for the wireless controller 20.

[0159] The wireless controller 20 includes a communication module 21, a power supply module 22, and at least one circuit control device 23, wherein the power supply module 22 is electrically connected to the communication module 21 and the circuit 100, and the power supply module 22 obtains the power of the circuit 100 and provides the power to the communication module 21. The communication module 21 is communicatively connected to the power supply module 22 and the circuit control device 23, wherein the communication module 21 receives a control signal sent by the self-powered switch 10 or the wireless device 300, and sends corresponding control instructions to the power supply module 22 and the circuit control device 23 based on the control signal, so as to adjust the working state of the circuit 100 and adjust the power supply mode of the power supply module 22.

[0160] like Figures 2A to 3AAs shown, the communication module 21 includes a first communication unit 211 and a second communication unit 212, and a control unit 213, wherein the first communication unit 211 is communicatively connected to the control unit 213, wherein the second communication unit 212 is communicatively connected to the control unit 213. The first communication unit 211 and the control unit 213 constitute a first communication protocol unit 201 communicatively connected to the wireless device 300, wherein the second communication unit 212 and the control unit 213 constitute a second communication protocol unit 202 communicatively connected to the self-powered switch. In short, the control unit 213 supports the operation of the first communication unit 211 and the second communication unit 212, so that the first communication unit receives and sends control information to the wireless device, and the second communication unit 212 receives control information sent by the self-powered switch 10.

[0161] It is understandable that the communication module 21 reduces the number of control units in a manner that the same control unit 213 supports the operation of two different communication units, thereby reducing the energy consumption of the communication module 21, so as to reduce the magnitude of the working current when the wireless controller 20 is working. It is understandable that since the wireless controller 20 is connected to the circuit 100 in series, the wireless controller 20 and the electrical device 200 are connected in series with each other. Therefore, when the electrical device 200 is in a dormant state, the current is the same as the working current of the wireless controller 20. By reducing the number of the control units 213 of the wireless controller 20, the working energy consumption and current of the wireless controller 20 can be effectively reduced, thereby reducing the magnitude of the current of the electrical device 200 in a dormant state, and avoiding abnormal startup of the electrical device 200 in a dormant state, such as flickering of lamps.

[0162] It can be understood that the first communication protocol unit 201 and the second communication protocol unit 202 receive the wireless control signals of the wireless device 300 and the self-powered switch 10 based on their respective communication protocols.

[0163] The first communication protocol unit 201 may, but is not limited to, adopt communication protocols such as Bluetooth communication protocol, WIFI communication protocol, and ZIGBEE communication protocol. For example, the first communication protocol unit 201 adopts the Bluetooth communication protocol, wherein the first communication unit 211 is a Bluetooth communication module, which operates in the Bluetooth communication frequency band, for example but not limited to 2400MHZ. The second communication protocol unit 202 may, but is not limited to, adopt a radio frequency communication protocol. For example, the second communication unit 212 of the second communication protocol 202 operates in the 200MHZ-1000MHZ frequency band. It is understandable that the frequency band range in which the first communication protocol unit 201 and the second communication protocol unit 202 operate is merely exemplary and not limiting.

[0164] Preferably, the second communication unit 212 is communicatively connected to the control unit 213, wherein the control unit 213 keeps the second communication unit 212 working uninterruptedly to receive burst information sent by the self-powered switch 10 at any time. It can be understood that when the self-powered switch 10 is operated to send burst control information, the burst control information is received by the second communication unit 212 to the control unit 213, and the control unit 213 controls the circuit control device 23 based on the control information.

[0165] Preferably, the first communication unit 211 is communicatively connected to the control unit 213, wherein the control unit 213 controls the first communication unit 211 to sleep intermittently to reduce the power consumption of the first communication unit 211. It is understandable that when the control unit 213 controls the first communication unit 211 to be in a dormant state, the first communication unit 211 is in a standby working state, thereby reducing the energy consumption of the first communication unit; when the control unit 213 controls the first communication unit 211 to be in a working state or a wake-up state, the first communication unit 211 is awakened to detect whether there is a wireless control signal. More preferably, the control unit 213 controls the first communication unit 211 to sleep periodically to reduce the power consumption of the first communication unit 211. Exemplarily, the control unit 213 controls the first communication unit 211 to be in an awake state or a working state every 10 milliseconds within 1 second to detect wireless signals in the space, and controls the first communication unit 211 to be in a dormant state every 990 milliseconds to reduce the energy consumption of the communication module 21, especially when the electrical device 200 is in a non-working state or a turned-off state, such as when the lamp is off. It is understandable that in this preferred embodiment of the present invention, the length and proportion of the working / sleeping time of the first communication unit 211 controlled by the control unit 213 are merely exemplary and not limiting. Most preferably, when the first communication unit 211 is in standby mode, the average current of the DC 3V voltage is 50uA-1mA, and the power consumption is less than 3mW.

[0166] It is understandable that the first communication unit 211 and the second communication unit 212 of the communication module 21 share the same control unit 213 to reduce the number of the controllers, thereby reducing the energy consumption of the communication module 21, especially the energy consumption of the electrical device 200 in the dormant state. Exemplarily, when the electrical device 200 is in the dormant or turned off state, the average power consumption of the first communication protocol unit 201 and the second communication protocol unit 202 combined does not exceed 5mA, and the power is not greater than 17mW.

[0167] In other words, the control unit 213 supports the communication protocol of the first communication unit 211 and the communication protocol of the second communication unit 212 at the same time, so that the control unit 213 can receive the control signal of the wireless device 300 through the first communication unit 211, and receive the control signal of the self-powered switch 10 through the second communication unit 212. The communication protocol of the first communication unit 211 and the communication protocol of the second communication unit 212 are stored in the control unit 213, so that the control unit 213 has the ability to support the first communication unit 211 to wirelessly communicate with the wireless device 300, and has the ability to support the second communication unit 212 to receive the control signal of the self-powered switch 10.

[0168] Referring to the accompanying drawings of the present invention Figure 3A , a schematic diagram of an implementation of the wireless controller 20 is shown. The first communication unit 211 and the control unit 212 of the communication module 21 are integrated into a chip, or the first communication unit 211 and the control unit 212 are packaged as an integrated circuit. That is, the first communication protocol unit 201 is implemented as an integrated chip or an integrated circuit, wherein the second communication unit 212 is communicatively connected to the integrated chip, wherein the integrated chip controls the second communication unit 212 to receive control information of the self-powered switch 10.

[0169] The first communication protocol unit 201 may be, but is not limited to, a chip supporting the Bluetooth communication protocol, a chip supporting the ZigBee communication protocol, and a chip supporting the WiFi communication protocol. Exemplarily, the first communication protocol unit 201 is implemented as a Bluetooth chip of model RTL8762CJ, wherein the Bluetooth chip stores the Bluetooth communication protocol and the Bluetooth control protocol. It is understandable that the model of the Bluetooth chip is only used as an exemplary quality and not a limitation, so the first communication protocol unit 201 can also be implemented as a chip of other models. Exemplarily, the second communication unit 212 is implemented as a radio frequency signal transceiver chip of model A7129, wherein the model of the chip is only used as an exemplary quality and not a limitation. The second communication unit 212 is communicatively connected to the Bluetooth chip, wherein the Bluetooth chip controls the operation of A7129 through the serial communication interface SPI to form the communication module 21 of dual-mode communication.

[0170] like Figure 2AAs shown, the first communication unit, the second communication unit and the control unit are packaged into an integrated circuit, wherein the first communication unit and the second communication unit operate in the same frequency band. Exemplarily, the first communication unit and the second communication unit operate in the Bluetooth frequency band, the first communication unit adopts the Bluetooth communication protocol so that the first communication unit exchanges data with the Bluetooth network, and the second communication unit adopts the short code communication protocol to receive self-powered control information. It can be understood that when the first communication unit, the second communication unit and the control unit are integrated into the same integrated circuit, the integrated circuit is in a continuous working state, the integrated circuit is in a continuous working state, and is no longer in a sleep state, and its continuous working current does not exceed 5mA@AC3.3V, and the power consumption is less than 17 mW.

[0171] like Figures 3A to 3C As shown, the control unit 213 includes a storage unit 2131 and a processor 2132, wherein the storage unit 2131 stores the communication protocol of the first communication unit 211 and the triplet of the first communication unit 211. By burning the communication protocol of the second communication unit 212 in the storage unit 2131, the control unit 213 has the ability to control the second communication unit 212. Exemplarily, when the first communication protocol unit 201 is configured as the Bluetooth chip, by burning the communication protocol of the second communication unit 212 in the storage unit 2131 of the Bluetooth chip, the Bluetooth chip has the ability to control the second communication unit 212, and the processor 2132 of the control unit 213 supports the operation of the second communication unit 212. In short, in this preferred embodiment of the present invention, the Bluetooth chip is connected to the second communication unit through the SPI interface, so that the communication module 21 has the ability of dual-mode communication, that is, the ability to receive and process the wireless communication protocol of the wireless device 100, and the ability to receive and process the wireless communication protocol of the self-powered switch 10. The storage unit 2131 is used to store the device ID of the self-powered switch, and store the configuration program of the communication protocol of the first communication unit 211 and the configuration program of the communication protocol of the second communication unit 212 .

[0172] It can be understood that the processor 2132 of the control unit 213 is connected to the first communication unit 211 and the second communication unit 212, wherein the processor 2132 demodulates the received control information and outputs corresponding control instructions to the circuit control device 23 to adjust the working state of the circuit control device 23, thereby controlling the working state of the electrical device 200. Preferably, the processor 2132 of the control unit 213 is implemented as an MCU (single-chip microcomputer), wherein the processor 2132 is communicatively connected to the storage unit 2131, obtains the configuration program from the storage unit 2131, and based on the configuration program, the processor 2132 receives and transmits data and calculates and processes the control data to obtain control instructions for controlling the circuit control device 23.

[0173] The first communication unit 211 demodulates the control information sent by the wireless device 300 to the control unit 213, and the control unit 213 obtains at least one control instruction for controlling the circuit control device 23 based on the control information, wherein the control unit 213 transmits the control instruction to the circuit control device 23 to control the working state of the circuit control device 23. The second communication unit 212 demodulates the control information sent by the self-powered switch 10 to the control unit 213, and the control unit 213 obtains at least one control instruction for controlling the circuit control device 23 based on the control information, wherein the control unit 213 transmits the control instruction to the circuit control device 23 to control the working state of the circuit control device 23.

[0174] like Figure 3B As shown, the processor 2132 of the control unit 213 includes an information processing module 21321, wherein the information processing module 21321 calculates the control instruction corresponding to the circuit control device 23 based on the control information demodulated by the first communication unit 211 or the control information demodulated by the second communication unit 212. The processor 2132 further includes a communication control module 21322, wherein the communication control module 21322 controls the working frequency, working time, and sleep time ratio of the first communication unit 211 and the second communication unit 212. The communication control module 21322 controls the first communication unit 211 to sleep periodically to save the energy consumption of the communication module 21. The communication control module 21322 controls the second communication unit 212 to keep working continuously so as to receive the control signal sent by the self-powered switch at any time.

[0175] The processor 2132 further includes a status update module 21323, wherein the status update module 21323 updates the working status information of the circuit control device 23 to the wireless device 300, so that the wireless device 300 knows the working status of the circuit control device 23. The status update module 21323 transmits the working status information of the circuit control device 23 to the wireless device 300 through the first communication unit 211 based on the wireless communication protocol. The control information sent by the self-powered switch 10 is transmitted to the wireless device 300 through the wireless controller 20, and other electrical devices are controlled by the wireless device 300. Accordingly, the processor 2132 further includes a protocol conversion module 21324, wherein the protocol conversion module 21324 converts the control information sent by the self-powered switch 10 based on the communication protocol of the wireless device, so that the first communication unit 211 transmits the converted control information to the wireless device 300. That is, the self-powered switch 10 generates device control information for controlling the wireless device 300 and is received by the wireless controller 20, wherein the second communication unit 212 of the communication module 21 receives and demodulates the control information to the control unit 213, wherein the protocol conversion module 21324 of the control unit 213 converts the control information based on the wireless communication protocol so that the first communication unit 211 transmits the control information to the wireless device 300.

[0176] Referring to the accompanying drawings of the present invention Figure 5A As shown, another optional implementation of the wireless controller 20 is shown, wherein the second communication module 212 and the control unit 213 of the communication module 21 of the wireless controller 20 are integrated into a chip, wherein the first communication module 211 is communicatively connected to the control unit 213. It is worth mentioning that in this preferred embodiment of the present invention, the packaging method of the communication module 21 of the wireless controller 20 is different from the packaging method of the first preferred embodiment mentioned above. Accordingly, the second communication protocol unit 202 is implemented as an integrated chip, wherein the communication protocol configuration program, triplet, etc. of the self-powered switch 10 are stored in the integrated chip. By burning the communication protocol of the first communication unit 211 in the control unit 213, the control unit 213 has the ability to control the operation of the first communication unit 211.

[0177] It is understood by those skilled in the art that the power consumption of the wireless controller 20 connected in series with the electrical device 200 will affect the stability and working state of the electrical device 200 connected in series with it. If the standby power consumption of the wireless controller 20 is large, the electrical device 200 connected in series with it will be unstable, especially the lamp with LED as the light source. LED is an efficient light source, and some 3-10W LED lamps will flicker as long as there is a current of about 100uA flowing through them.

[0178] The power supply module 22 is electrically connected to the communication module 21 and the circuit 100, wherein the power supply module 22 obtains electric energy from the circuit 100 to support the operation of the communication module 21. The power supply module 22 includes an electric energy conversion unit 221 and a pulse width power supply unit 222, wherein the electric energy conversion unit 221 and the pulse width power supply unit 222 are connected to the circuit 100, and convert the current in the circuit 100 into the working current of the communication module 21 to support the operation of the communication module 21. When the electrical device 200 is in a power-off state, a sleep state, or the circuit control device 23 disconnects the circuit 100, the electric energy conversion unit 221 provides electric energy to the communication module 21. When the electrical device 200 is in a working state, or the circuit control device 23 connects the circuit 100, the pulse width power supply unit 222 provides electric energy to the communication module 21. It is worth mentioning that the power conversion unit 221 and the pulse width power supply unit 222 of the power supply module 22 convert the high voltage power of the circuit 100 into low voltage DC power to support the operation of the communication module 21. Preferably, the power conversion unit 221 and the pulse width power supply unit 222 of the power supply module 22 convert the high voltage AC power of the circuit 100 into DC1.5-DC12V DC power.

[0179] It is worth mentioning that the power conversion unit 221 and the pulse width power supply unit 222 are located at one end of the circuit control device 23, that is, the side close to the input end of the circuit 100. The power conversion unit is electrically connected to the live wire 110 and the neutral wire 120 of the circuit 100. When the electrical device 200 is in a dormant state, or when the circuit control device 23 controls the circuit 100 to be disconnected, the power conversion unit 221 converts the power of the circuit 100 and transmits the converted power to the communication module 21. Preferably, in the first preferred embodiment of the present invention, the power conversion unit 221 is a high-efficiency AC-DC unit, so that the leakage current of the circuit 100 when the electrical device 200 is turned off provides working power for the wireless controller 20. The power conversion unit 221 is a switching power supply, and its working current is less than 150uA@AC220V. Exemplarily, in this preferred embodiment of the present invention, a LNK3202D switching power supply chip is used to provide standby working power for the communication module 21 of the wireless controller 20. It is understood that the type and model of the power conversion unit 221 are merely exemplary and not limiting.

[0180] Those skilled in the art can understand that when the electrical device 200 is in a dormant state, the working current generated by the power conversion unit 221 flows through the electrical device 200, such as a lamp, and will not cause abnormal startup of the electrical device 200.

[0181] The pulse width power supply unit 222 is connected to the live wire 110 of the circuit 100 in series. When the circuit control device 23 is connected to the circuit 100, the pulse width power supply unit 222 is controlled by the control unit 213 of the communication module 21 to obtain the power of the circuit 100. It can be understood that when the circuit control device 23 is connected to the circuit 100, the voltage difference between the power conversion unit 221 and the circuit 100 is zero, so that the power conversion unit 221 stops working, and the control unit 213 controls the pulse width power supply unit 222 to start, so as to provide power to the communication module 21.

[0182] When the communication module 21 receives the control information sent by the self-powered switch 10 or receives the control information of the wireless device 300, and controls the circuit control device 23 to turn on the circuit 100, the control unit 213 of the communication module 21 controls the pulse width power supply unit 222 to draw power from the circuit 100. The pulse width power supply unit 222 periodically draws power from the circuit 100 based on the control signal of the control unit 213 to support the operation of the communication module 21. The pulse width power supply unit 222 is connected in series to point a and point b of the live wire 110, wherein the pulse width power supply unit 222 obtains AC power support from point a and point b of the live wire in an intermittently disconnected manner.

[0183] like Figure 4 As shown, the pulse width power supply unit 222 is controlled by the control unit 213, and periodically obtains AC power from the circuit 100, and converts the AC power of the circuit 100 into low-voltage DC power to support the operation of the communication module 21. Preferably, the pulse width power supply unit 222 periodically draws power near the zero-point potential of the AC power of the circuit 100 based on the control signal of the control unit 213, so that the pulse width power supply unit 222 obtains 10-30V AC power between points a and b. The pulse width power supply unit 222 converts the AC10-30V AC power into DC1.5-5V DC power to support the operation of the communication module 21.

[0184] Preferably, in the first preferred embodiment of the present invention, the pulse width power supply unit 222 is a MOS tube, wherein the MOS tube is electrically connected to the point a and point b of the live wire 110 of the circuit 100. When the circuit control device 23 is connected to the circuit 100, the pulse width power supply unit 222 is controlled by the control unit 213 to be periodically disconnected for a period of time near the zero point of the alternating current, wherein the MOS tube obtains electrical energy based on the periodic disconnection of the MOS field effect tube near the zero point of the alternating current. It can be understood by those skilled in the art that the pulse width power supply unit 222 periodically disconnects the live wire 110 of the circuit 100 with a narrow pulse width to obtain electrical energy from the circuit 100. It is worth mentioning that the time for the pulse width power supply unit 222 to disconnect the power supply of the live wire 110 is extremely short, which will not affect the normal operation of the electrical device 200, and the human eye and senses will not detect the change.

[0185] like Figure 3AAs shown, the circuit control device 23 is connected in series to the live wire 110 of the circuit 100, wherein the circuit control device 23 is controlled by the control unit 213 to control the working state of the electrical device 200. Preferably, the circuit control device 23 controls the working state of the live wire 110 of the circuit 100, thereby controlling the connection and disconnection of the electrical device 200. In this preferred embodiment of the present invention, the circuit control device 23 can be but is not limited to a relay switch, wherein the relay switch is set on the live wire of the circuit 100. When the relay switch is energized, the circuit 100 is connected, and the electrical device 200 is in a working state, thereby causing the two ends of the power conversion unit 221 to be short-circuited and stop working. In short, when the circuit control device 23 is in the energized state, the electrical device 200 is connected, wherein the power conversion unit 221 stops working, and the pulse width power supply unit 222 is controlled by the control unit 213 to periodically take power to support the operation of the communication module 21.

[0186] Referring to the accompanying drawings of the present invention Figure 5B As shown, another optional implementation of a wireless controller 20 according to the present invention is explained in the following description. The wireless controller 20 includes a communication module 21, a power supply module 22, and a circuit control device 23, wherein the communication module 21 has the same structure and function as the communication module 21 of the first preferred embodiment, and the difference lies in the power supply module 22 and the circuit control device 23. The power supply module 22 and the circuit control device 23 are communicatively connected to the communication module 21, and the circuit control device 23 is controlled by the control unit 213 of the communication module 21, thereby controlling the working state of the circuit 100. The power supply module 22 is a high-efficiency AC-DC conversion unit. When the power-consuming device 200 is in a dormant state or the circuit 100 is in a disconnected state, the power supply module 22 draws power from the circuit 100 to support the operation of the communication module 21.

[0187] When the communication module 21 receives the control information of the self-powered switch 10, or receives the control information of the wireless device 300 to control the operation of the electrical device 200, the control unit 213 of the communication module 21 controls the circuit control device 23 to connect the circuit 100, so that the power supply module 22 stops working, and the circuit control device 23 takes power from the circuit 100 to support the operation of the communication module 21. In this preferred embodiment of the present invention, the circuit control device 23 can be but not limited to a semiconductor device, wherein the semiconductor device can be a bidirectional thyristor, a triode, a field effect transistor, or a thyristor, etc., wherein the semiconductor device is connected in series to the live wire 110 of the circuit 100. The circuit control device 23 controls the working state of the circuit 100 based on the control instruction of the control unit 213, and when the circuit 100 is in the connected state, the live wire of the circuit 100 is periodically disconnected to take power from the circuit 100.

[0188] like Figure 2A As shown, the self-powered switch 10 includes at least one power generation unit 11, an energy storage unit 12, an energy extension unit 13, and a communication unit 14, wherein the power generation source 11 generates electric energy by being pressed, and stores the electric energy in the energy storage unit 12, wherein the electric energy stored in the energy storage unit 12 is transmitted to the communication unit 14 via the energy extension unit 13. The communication unit 14 encodes a control message based on the communication protocol of the self-powered switch, and sends the control message to the wireless controller 20, so that the wireless controller 20 controls the working state of the electrical device 200 based on the control message, or transmits the control message to the wireless device 300 via the wireless controller 20.

[0189] The communication unit 14 sends a short code communication protocol, wherein the short code communication protocol is received by the second communication unit 212 of the wireless controller 20. The message length of the short code communication protocol sent by the communication unit 14 is less than 15 bytes, and the content of the message includes at least a header, an address, service content, a device code, and a verification code.

[0190] Preferably, in this preferred embodiment of the present invention, the message generated by the communication unit 14 is wirelessly sent in space in a broadcast manner so as to be received by the second communication unit 212 of the wireless controller 20. In short, the broadcast mechanism is adopted between the self-powered switch 10 and the wireless controller 20, which can omit the long process of pairing the self-powered switch 10 and the wireless controller 20, thereby reducing the demand of the self-powered switch 10 for power supply capability and further reducing power consumption.

[0191] It is worth mentioning that the communication unit 14 can broadcast messages in a general broadcast mode or a directional broadcast mode. When the communication unit 14 adopts the general broadcast mode, the communication unit 14 broadcasts cyclically on multiple channels so that the wireless controller 20 receives the broadcast information of one of the channels. When the communication unit 14 adopts the directional broadcast mode, the communication unit 14 broadcasts on a preset channel so that the receiving channel of the wireless controller 20 corresponds to the channel of the self-powered switch.

[0192] Preferably, in this preferred embodiment of the present invention, the channel through which the second communication protocol unit receives the short code communication protocol is Bluetooth broadcast channel 37, 38, 39. It is worth mentioning that the broadcast channel of the second communication protocol unit is only exemplary and not limiting.

[0193] like Figure 8 As shown, the self-powered switch 10 further includes at least one electrical device button 15 and at least one network device button 16, wherein when the electrical device button 15 is pressed, the communication unit 14 of the self-powered switch 10 generates and sends control information for controlling the electrical device 200, and when the network device button 16 is pressed, the communication unit 14 of the self-powered switch 10 generates and sends control information for controlling the electrical device in the wireless device 300. In short, the self-powered switch 10 can generate control information corresponding to the electrical device according to different electrical devices.

[0194] It is worth mentioning that the control information of the self-powered switch 10 and the working state information of the electrical device 200 are transmitted to the wireless device 300 by the communication module 21 of the wireless controller 20, or the working state information of the electrical device 200 is uploaded to a cloud server 400 through the wireless device 300. The communication module 21 of the wireless controller 20 receives the control information of the electrical device 200 from the cloud server 400 through the wireless device 300, so as to control the working state of the electrical device 200 based on the control information.

[0195] like Figure 6As shown, a wireless connection method and a control method of a wireless controller 20 according to the above preferred embodiment of the present invention are explained in the following description. When the electrical device button 15 of the self-powered switch 10 is operated, the self-powered switch 10 generates and transmits a control information to start the electrical device 200. The second communication unit 212 of the communication module 21 of the wireless controller 20 receives the control information transmitted by the self-powered switch 10, and demodulates the control information based on the self-powered communication protocol, wherein the second communication unit 212 transmits the demodulated control information to the control unit 213, and the control unit 213 controls the circuit control device 23 to start based on the demodulated control information, so that the circuit 100 is turned on, and the electrical device 200 is in a working state. When the circuit 100 is turned on, the power conversion unit 221 of the power supply module 22 stops working, wherein the control unit 213 controls the pulse width power supply unit 222 to take power from the circuit 100 to support the operation of the communication module 21.

[0196] When the electrical device button 15 of the self-powered switch 10 is operated, the self-powered switch 10 generates and transmits a control information for shutting down the electrical device 200. The second communication unit 212 of the communication module 21 receives the control information transmitted by the self-powered switch 10, and demodulates the control information based on the self-powered communication protocol, wherein the second communication unit 212 transmits the demodulated control information to the control unit 213, and the control unit 213 controls the circuit control device 23 to shut down based on the demodulated control information, so that the circuit 100 is disconnected, and the electrical device 200 is in a dormant or disconnected state. When the circuit 100 is disconnected, the power conversion unit 221 of the power supply module 22 starts to draw power from the circuit 100 to support the operation of the communication module 21, wherein the pulse width power supply unit 222 is controlled by the control unit 213 and stops working.

[0197] When the network device button 16 of the self-powered switch 10 is operated, the self-powered switch 10 generates and transmits a control information for shutting down a device in the wireless device 300. The second communication unit 212 of the communication module 21 receives the control information transmitted by the self-powered switch 10, and demodulates the control information based on the self-powered communication protocol, wherein the second communication unit 212 transmits the demodulated control information to the control unit 213. The control unit 213 modulates the control information to the first communication unit 211 based on the network communication protocol, and transmits the modulated control information to the device in the wireless device 300 through the first communication unit 211, so that the device can control the working state of the switch based on the control information.

[0198] It can be understood that the control information of the wireless controller 20 is sent to the wireless device 300 by the first communication unit 211 in a wireless transmission manner, so that the wireless device 300 knows the working status and control information of the electrical device 200 .

[0199] The wireless device 300 sends control information (startup and shutdown) to the wireless controller 20, wherein the control information is received and demodulated by the first communication unit 211, wherein the control unit 213 controls the working state of the circuit control device 23 based on the demodulated control information to control the working state of the electrical device 200. It is worth mentioning that in order to ensure the security of the wireless device 300, the wireless device 200, such as the METH network, periodically updates the secret key in the wireless controller 20 to prevent the terminal device of the wireless controller 20 from being copied.

[0200] like Figure 2B As shown, the wireless controller 20 further includes a control switch 24, wherein the control switch 24 is arranged in the control unit 213 of the communication module 21. The control switch 24 controls the startup of the wireless controller 20, and controls the working state of the electrical device 200 by operating the control switch 24. The control switch 24 controls the pairing connection between the wireless controller 20 and the self-powered switch 10, and controls the network connection between the wireless controller 20 and the wireless device 300. In other words, when the control switch 4 is pressed, the wireless controller 20 automatically realizes the pairing connection with the wireless device 300.

[0204] In the wireless connection method, the control unit 213 stores the wireless communication protocol and the self-powered communication protocol, so that the control unit 213 has the function of communicating with the wireless device 300 and the ability to communicate with the self-powered switch 10. The second communication unit 212 receives a control message sent by the self-powered switch 10, and demodulates the control message to the control unit 213 based on the self-powered communication protocol, so that the control unit 213 controls a circuit control device 23 of the wireless controller 20 based on the demodulated control message. The first communication unit 211 receives a control message of the wireless device 300, and demodulates the control message to the control unit 213 based on the wireless communication protocol, so that the control unit 213 controls a circuit control device 23 of the wireless controller 20 based on the demodulated control message. The control unit 213 modulates the control message of the circuit control device 23 based on the wireless communication protocol, and sends the control message to the wireless device 300 through the first communication unit 211.

[0205] In the steps of the above-mentioned wireless connection method, the self-powered communication protocol of the second communication unit 212 is stored in the control unit 213 by burning it in the control unit 213 of the first communication protocol unit 201, so that the control unit 213 has the ability to communicate with the self-powered switch.

[0239] like Fig. 10A As shown, the communication module 21a is implemented as a dual-protocol communication processing device, that is, a module with the receiving and processing capabilities of two different communication protocols in one communication module, which can process two or more messages of different formats simultaneously or separately. In the present invention, it refers to a communication module that is capable of receiving and processing wireless communication protocols (Bluetooth protocol, WiFi protocol or ZigBee protocol) and self-powered communication protocols at the same time.

Exemplarily, the wireless device 300 may be, but is not limited to, a MESH mesh network. It is understood that the operating frequency band of the two-way communication unit 211a is merely exemplary and not limiting.

[0246] It is worth mentioning that the self-powered switch 10a sends a short code communication protocol in a broadcasting manner, wherein the communication frequency band of the self-powered switch 10a is 1000MHZ-5000MHZ, so that the short code communication protocol sent by the self-powered switch 10a can be received by the wireless controller 20a. The message length of the short code communication protocol sent by the self-powered switch 10a is less than 15 bytes, wherein the message length content at least includes a header, an address, a service content, a device code, and a verification code. The self-powered switch 10a sends the same message at least twice so that the wireless controller 20a can receive the message.

[0247] It is worth mentioning that when the message is broadcasted for the first time, it is received by the two-way communication unit 211a, and the data broadcasted by the self-powered device is stored in the storage unit 2131a through the control switch 24a or the setting of the program, so as to form a pairing relationship between the transmitter and the two-way communication unit 211a. When the two-way communication unit 211a receives the same message again, the processor 2132 outputs data or level through the I / O interface to control the circuit control device 23a to perform the set control action.
