Description

[Technical Field]

[0001] The present invention relates to the technical field of single-wire control and communication, and more particularly to a single live wire intelligent remote control method, a single live wire intelligent remote control device and a system using the same. [Background technology]

[0002] The design of modern architecture and interior spaces not only considers aesthetics and practicality, but also increasingly attaches importance to the concepts of energy conservation and intelligent control. Take ceiling fan control as an example, most of the traditional wall-mounted remote control panels use a button to output commands, and each time a button is pressed, the fan's operating state or rotation speed is changed accordingly. Summary of the Invention [Problem to be solved by the invention]

[0003] However, this control mode has a clear drawback in that when multiple fans are connected to one control panel, the operating status of each fan will not all be the same and will become out of sync.

[0004] To solve this problem, conventional products typically adopt a one-to-one design, where one control panel is connected to only one fan or lamp. However, this approach faces several limitations in practical applications. For example, in large public facilities, the openness and compartmentalization of the space necessitates centralized control of multiple fans or multiple sets of lamps in one location to ensure a unified and synchronized environment within the area. The traditional one-to-one design is clearly insufficient in such situations. Therefore, the industry is actively researching and developing new solutions that support one-to-multiple control, hoping to meet the diverse needs of large facilities—energy conservation, smart technology, and centralized control—and improve convenience and management efficiency.

[0005] Therefore, the inventors of the present invention believed that the above drawbacks could be improved, and as a result of extensive research, they came up with the proposal of the present invention, which rationally and effectively improves the problems.

[0006] The present invention has been made in view of the above circumstances, and aims to solve the above problems, namely, a main object of the present invention is to provide a single live wire intelligent remote control method, a single live wire intelligent remote control device, and a system using the same that meet various demands for energy saving, smartness, and centralized control in large facilities and improve convenience and management efficiency.

A control method according to a preferred embodiment of the present invention achieves highly efficient centralized control of one or more devices by installing a wall-mounted remote control between a live wire and a ceiling / wall device. The wall-mounted remote control converts user-initiated ceiling / wall device operation commands into a series of digitized transmission data. This data is encapsulated in a special AC voltage waveform and transmitted to each ceiling / wall device via the live wire that originally supplied power.

The live line LW is used to supply AC voltage.

[0022] Generally, the wall-mounted remote control unit 101 is fixed or attached to a wall and includes a control panel. The wall-mounted remote control unit 101 includes a first end and a second end, the first end of which is connected to a live line LW. The power cable 102 is attached to the wall and includes a first end and a second end, the first end of which is connected to the second end of the wall-mounted remote control unit 101.

The ceiling / wall-mounted device 11 includes a first input end and a second input end, the first input end of which is connected to the second end of the power cable 102, and the second input end of which is connected to a neutral line NW.

[0023] In this embodiment, the wall-mounted remote control apparatus 101 can simultaneously control multiple ceiling / wall-mounted devices 11 via a single power cable 102. Figure 2 is a schematic diagram of a single live-wire intelligent remote control system according to a preferred embodiment of the present invention. As shown in the figure, in this embodiment, the wall-mounted remote control apparatus 101 includes a switch 201, a rotating fan speed controller 202, a rotating light controller 203, and an infrared receiver 204. In addition to transmitting AC power voltage, the power cable 102 also transmits control signals via a single live-wire controlled ceiling / wall-mounted device 11. Technical details will be described in subsequent embodiments.

As shown in the figure, the wall-mounted remote control device 101 includes a full-bridge rectifier 301, a DC converter 302, a first zero-crossing detection circuit 303, a second zero-crossing detection circuit 304, a microcontroller 305, a control panel 306, a switch driver 307, and a bidirectional switch device 308. The bidirectional switch device 308 is implemented by a first metal oxide semiconductor field-effect transistor Q1 and a second metal oxide semiconductor field-effect transistor Q2. The two metal oxide semiconductor field-effect transistors Q1 and Q2, connected in series in reverse, are used to control the output phase of the AC voltage supplied to the ceiling / wall-mounted device 11.

[0025] The first zero-crossing detection circuit 303 and the second zero-crossing detection circuit 304 are used to detect and synchronize the AC voltage, and then output the detected phase signals DPS1 and DPS2 to the microcontroller 305, respectively. The microcontroller 305 receives settings from the user interface of the control panel 306, converts the settings into a digital sequence of transmission data, and determines the output of the phase control signal PCS based on the digital sequence of transmission data. The switch driver 307 is used to drive two metal oxide semiconductor field effect transistors Q1 and Q2 connected in series in reverse direction based on the phase control signal PCS. Thus, the two metal oxide semiconductor field effect transistors Q1 and Q2 control the AC voltage supplied to the ceiling / wall-mounted device 11 in a phase-switched manner based on the switch control of the phase control signal PCS. In this embodiment, a switch control module is implemented by the switch driver 307 and the metal oxide semiconductor field effect transistors Q1 and Q2, and is used to control the conduction state between the first terminal (hot line) LW and the second terminal N1 of the wall-mounted remote control equipment 101 based on the transmission data. Those skilled in the art will recognize that the switch control module can be implemented using other circuits such as silicon controlled rectifiers (SCRs), triacs (TRIACs), etc., and the present invention is not limited thereto.

[0026] FIG. 4 is a circuit block diagram of a ceiling / wall-mounted device 11 of a single live wire intelligent remote control system according to a preferred embodiment of the present invention. As shown in FIG. 4, in this embodiment, the ceiling / wall-mounted device 11 is a ceiling fan or a wall-mounted fan. The ceiling / wall-mounted device 11 includes a full-bridge rectifier 401, a zero-crossing detection circuit 402, a microcontroller 403, a brushless DC motor circuit 404, and a bleeder circuit 405. The first input terminal of the full-bridge rectifier 401 of the ceiling / wall-mounted device 11 is connected in series with a node N1 of the wall-mounted remote control unit 101 to receive a phase-switched AC voltage. The second input terminal of the full-bridge rectifier 401 of the ceiling / wall-mounted device 11 is connected to a neutral line NW. The zero-crossing detection circuit 402 detects the voltage at the positive output terminal of the full-bridge rectifier 401 and outputs a detected phase signal DPS3.

[0027] The microcontroller 403 receives the detected phase signal DPS3 from the zero-crossing detection circuit 402 and demodulates the detected phase signal DPS3 to obtain a transmitted data digital sequence that may include speed and direction information. In this way, the microcontroller 403 can control the rotation speed and / or rotation direction of the three wires U, V, and W of the brushless motor driven by the brushless DC motor circuit 404 based on the transmitted data.

[0028] In this embodiment, the bleeder circuit 405 and the full-bridge rectifier 401 are connected in series to continuously supply sufficient operating current to the wall-mounted remote control device 101. To reduce unnecessary bleeder current, the bleeder circuit 405 is implemented with a constant current circuit and one switch (not shown in FIG. 4), and the conduction time of the switch is controlled by the microcontroller 403. However, a person skilled in the art will understand that a designer can change the power supply method of the wall-mounted remote control device 101, and the present invention is not limited to this.

[0029] FIG. 5 is a circuit block diagram showing a ceiling / wall-mounted device 11 of a single live wire intelligent remote control system according to a preferred embodiment of the present invention.

The ceiling / wall-mounted device 11 includes a full-bridge rectifier 501, a zero-crossing detection circuit 502, a microcontroller 503, an LED lamp circuit 504, and a DC power supply circuit 505. Similar to the ceiling fan shown in FIG. 4, in this preferred embodiment, the LED lamp circuit demodulates the AC voltage supplied by the wall-mounted remote control device 101 to obtain control commands from the transmission data, thereby achieving simultaneous control of functions such as brightness and color temperature.

[0030] Due to space and height limitations for the LED lamp control circuit, in a preferred embodiment of the present invention, a DC power supply circuit 505 for the microcontroller 503 of the ceiling LED light circuit is implemented using a circuit consisting of a continuously operating constant current source ISRC and a 5V Zener diode Z1. This rectifies the 5V DC voltage to power the microcontroller 503. A zero-crossing detection circuit 502 and a full-bridge rectifier 501 are connected in series to obtain a full-wave AC voltage and provide the detected phase signal DPS4 to the microcontroller 503, which demodulates the digital sequence of the transmitted data to obtain control commands. In this embodiment, the LED lamp circuit 504 is implemented using two constant current drivers, each driving two LED lamps with different color temperatures. The microcontroller 503 can adjust the PWM duty cycle to control the corresponding current for the LED lamps, thereby controlling the color temperature and brightness. 4 and 5 are the same device, such as a ceiling light fan, full-bridge rectifier 401 and full-bridge rectifier 501 may be the same full-bridge rectifier, zero-crossing detection circuit 502 and zero-crossing detection circuit 402 may be the same zero-crossing detection circuit, and microcontroller 503 and microcontroller 403 may be the same microcontroller. Therefore, the present invention is not limited thereto.

In a preferred embodiment of the present invention, different phase switchings correspond to different logic data. In this embodiment, the duty ratio of the detected phase signal 604 indicates the phase switching of the AC voltage. For example, a logic "1" corresponds to a small duty ratio of the detected phase signal 604, and a logic "0" corresponds to a large duty ratio of the detected phase signal 604.

[0032] FIG. 7 is a schematic diagram illustrating a transmission data modulation scheme for a single live wire intelligent remote control system according to a preferred embodiment of the present invention. Referring to FIG. 7, a logic "1" is modulated by cutting a 2 ms AC voltage phase cycle, a logic "0" is modulated by cutting a 1.5 ms AC voltage phase cycle, and a NULL value or spacer is modulated by cutting a 1.75 ms AC voltage phase cycle. The transmission data sequence further includes a rotation speed field 701, a rotation direction field 702, a lamp brightness field 703, a lamp color field 704, and a spacer field 705. The rotation speed field includes 4 bits of data, the rotation direction field includes 1 bit of data, the lamp brightness field includes 4 bits of data, the lamp color field includes 3 bits of data, and the spacer field includes 4 bits of NULL value data. In this embodiment, the wall-mounted remote control device 101 generates a series of control commands by turning off different duty cycles. "0" is 1.5 ms, "1" is 2.0 ms, and the NULL value bit is 1.75 ms. In this embodiment, the ceiling / wall-mounted device 11 can determine that the next AC voltage contains the control command by receiving the NULL value bit, and then demodulate the transmitted data.

[0033] Those skilled in the art will understand the essential spirit of the present invention, and the modulation / encryption method described above is merely an example. Those skilled in the art will be able to modify the timing, e.g., from 1.5 ms to 1 ms, and / or modify the bit count, NULL value bit, character spacing, or even the entire protocol, based on the preferred embodiment of the present invention. Therefore, the present invention is not limited to these. Furthermore, while the above embodiment provides only one LED lamp and one ceiling fan, those skilled in the art will understand that the above embodiment employs digital control of live AC voltage lines, allowing one wall-mounted remote control device 101 to simultaneously control multiple lamps and / or ceiling fans. Therefore, the present invention is not limited to these.

In step S902, it is determined whether a NULL value has been received. If not, the process returns to step S902. If received, the process proceeds to step S903. In step S903, determine whether the length of the NULL value is equal to the threshold T. If not, return to step S902. If equal, proceed to step S904. In step S904, the ceiling / wall-mounted device receives the settings of the ceiling / wall-mounted device by detecting the off-phase of the AC voltage on the power line and decoding the transmitted data.

[0036] The circuit block diagrams of Figures 3 to 5 are merely used for illustrative purposes. A person skilled in the art can modify part or all of the circuits within the essential spirit of the above-described embodiments of the present invention. For example, the switch driver and two metal oxide semiconductor field effect transistors may be replaced with other switches. For example, as shown in Figure 5, if the ceiling / wall-mounted device 11 is changed to a gas discharge light source, the LED lamp circuit 504 is changed to an electronic ballast. Therefore, the present invention is not limited to the above-described circuits.

[0037] In summary, a novel control method according to a preferred embodiment of the present invention achieves highly efficient centralized control of one or more devices by installing a wall-mounted remote control between a live wire and a ceiling / wall device. The wall-mounted remote control converts user-initiated ceiling / wall device operation commands into a series of digitized transmission data. This data is encapsulated in a special AC voltage waveform and transmitted to each ceiling / wall device via the live wire that originally supplied power. The key to this transmission method is that the logic 1 and logic 0 of the digital data correspond to different off-phase voltages, and specific intervals are inserted at the beginning and end of transmission to form an AC voltage waveform capable of carrying information. This achieves both power supply to the device and digital data transmission. By adopting a digitized serial transmission mode and utilizing the existing live wire, no separate clock circuit is required, which naturally eliminates synchronization issues and significantly simplifies the control system. Incidentally, this type of transmission mode allows one wall-mounted control equipment to synchronously control multiple ceiling / wall-mounted devices, truly realizing one pair of multiple centralized control, meeting the control requirements in large facilities and improving energy utilization efficiency and management convenience.
