[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0028] refer to Figure 1-5 A DMX signal glass panel controller includes an overload detection circuit, a microcontroller, a DMX signal converter, a touch chip circuit, a DC-DC power supply module, the DC-DC power supply module being connected to the microcontroller and used to convert the input high-voltage DC power into a stable and smooth voltage to supply the microcontroller, a DMX signal output module, and a touch chip circuit.

[0029] The DMX signal output module is connected to the microcontroller and is used to convert the microcontroller's TTL signal and input the TTL signal to the DMX signal converter. The RS485 chip then synchronously outputs the DMX signal.

[0030] The LED indicator circuit, connected to a microcontroller, is used to synchronously indicate whether the function of the touch key on the glass panel is turned on or off when a finger touches the panel key. When a finger presses the panel key, the indicator light lights up; when the panel key is touched again, the LED indicator light turns off.

[0031] MOSFET driver circuit, connected to a microcontroller, is used to drive the motor vibrator and to turn the touch key function on and off when touched by a finger on the glass panel.

[0032] The storage circuit, connected to the microcontroller, is used to store scenes edited on the computer, so that downloaded scenes can be automatically recalled when there is no network connection.

[0033] The DC-DC power module uses a diode D1 to filter the 12V DC power supply through capacitors C31 and C35 to generate a stable 12V DC voltage. The voltage is then reduced to 3.3V by a switching regulator circuit consisting of an MP2451 chip, an inductor, and a freewheeling diode, which is used to power the microcontroller module and other modules.

[0034] The microcontroller sends high and low levels to drive the MOSFET to conduct. The 3.3V DC current passes through the motor oscillator, and the high voltage D15 diode absorbs the high voltage to protect the motor oscillator.

[0035] The touch chip circuit consists of touch chip U2 connected to the microcontroller serial port and peripheral components C30, C26, C23, and C29. The pins of touch chip U2 form touch pads with resistors R2 and T66.

[0036] The RS485 U11 chip is connected to the microcontroller's serial port and, together with peripheral components C55, R42, and R41, forms a DMX transmit / receive circuit. Connected to the microcontroller, it is used to convert the microcontroller's TTL signals. When the RS485 U11 receives the TTL signal, it outputs a standard DMX signal through signal conversion to control the corresponding DMX decoder.

[0037] Specifically, this utility model provides a DMX glass panel controller that outputs standard DMX signals and outputs different commands according to the area touched by a finger to achieve different functions.

[0038] DC-DC power supply module, DMX signal output module, LED indicator circuit, overload detection circuit, microcontroller, DMX signal converter, touch chip circuit, MOSFET drive circuit, storage circuit;

[0039] DC-DC power module, connected to a microcontroller, used to convert the input high-voltage DC power into a stable and smooth voltage to supply the microcontroller; DMX signal output module; touch chip;

[0040] The DMX signal output module connects to the microcontroller and is used to convert the microcontroller's TTL signal and input the TTL signal to the DMX signal converter via an RS485 chip, and then synchronously output the DMX signal.

[0041] The LED indicator circuit, connected to the microcontroller, is used to synchronously indicate whether the function of the touch key on the glass panel is turned on or off when a finger touches the panel key. When a finger presses on the panel key, the indicator light lights up; when the panel key is touched again, the LED indicator light turns off.

[0042] The storage circuit, connected to the microcontroller, is used to store scenes edited on the computer, so that downloaded scenes can be automatically recalled when there is no network connection.

[0043] The MOSFET driver circuit, connected to the microcontroller, drives the motor oscillator. When a finger touches the touch button on the glass panel to turn the function on or off, the motor oscillator vibrates, giving the user a tactile sensation. This ensures that each touch button press triggers the button's function.

[0044] as follows Figure 2 As shown, the 12V DC power is filtered by diode D1, then filtered by C31 and C35 to generate a stable 12V DC voltage. Then, the voltage is reduced to 3.3V by a switching regulator circuit composed of MP2451, inductor, freewheeling diode, etc. This 3.3V power supply is used to power the microcontroller module and other modules.

[0045] like Figure 3 As shown, when the microcontroller sends high and low levels to drive the MOS Q12 transistor, and the base of the transistor is connected to a high level of approximately 3V, the MOS transistor conducts. The 3.3V DC current passes through the motor oscillator, absorbing the high voltage. The D15 diode is used to protect the motor oscillator. Thus, the motor oscillator starts to vibrate. If the base of the transistor is connected to a low level, the motor oscillator stops vibrating. Each rapid switching generates an induced electromotive force in the motor, which may be higher than 3.3V. The D15 diode can absorb the voltage higher than 3.3V, protecting external devices from damage.

[0046] like Figure 4 As shown, the touch chip U2 is connected to the microcontroller's serial port and forms a touch circuit with peripheral components C30, C26, C23, and C29. The touch chip pins form touch pads with resistors such as R2 and T66. If a finger touches the touch pad, the touch chip will detect it and send a signal to the microcontroller, which will then output accordingly.

[0047] like Figure 5 As shown, the RS485 U11 chip is connected to the microcontroller's serial port and, together with peripheral components C55, R42, and R41, forms a DMX transmit / receive circuit. Connected to the microcontroller, it converts the microcontroller's TTL signals. The RS485 U11 receives the TTL signal and outputs a standard DMX signal through signal conversion to control the corresponding DMX decoder.

[0048] The working principle of this utility model is as follows: This utility model provides a DMX signal glass panel controller, which is controlled by touching the glass panel. It sends standard DMX signals, receives DMX signals, and decodes them to achieve different scene brightness changes. It conforms to the DMX512 / 1990 international standard protocol with 1024 DMX output channels, can control 340 RGB lights, and can adjust various lights such as full color, color temperature, and single color. It has real-time clock and calendar trigger functions, can be programmed and controlled online via USB, has a built-in 8G high-speed memory card for independent control, 4 external dry contacts and a set of 485 external triggers (RJ45), 8 touch scene buttons, 4 scene pages, and supports 32 offline scenes. Touch color / brightness / speed sliders are used, and up to 50 devices can be interconnected on a local area network for control via UDP / TCP / HTTP. After networking, it can receive synchronized scenes, brightness, and speed from DMX-03 and DMX-P08 (main mode).

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
