[0027] Example 1

[0028] refer to Figure 1 and Figure 2 As shown, this utility model proposes a roller shutter door controller, including a circuit board. The circuit board is equipped with a voltage conversion module, a control module, an execution module, and wiring terminals for connecting to external devices. The input terminal of the voltage conversion module is connected to the mains power supply via the wiring terminals, and the output terminal is connected to the control module and the execution module, converting the mains voltage into the voltage required for the operation of the control and execution modules. The execution module includes a relay and a switch. The relay is connected to the control module, and the switch and relay work together to control the roller shutter door. The control module includes a control chip, which receives and executes control commands. Working with the relay, it converts electrical signals into on / off control of the roller shutter door motor, driving the roller shutter door to move. The wiring terminals are located at the edge of the circuit board for connecting to the mains power supply and external devices such as the roller shutter door motor.

[0029] The circuit board is also equipped with indicator lights, which are connected to the control module and are used to indicate the working status of the roller shutter door controller.

[0030] Preferably, the voltage conversion module includes a surge protection unit, a rectifier and filter unit, and a voltage regulator unit connected in sequence. The surge protection unit is connected in series with the mains input circuit through a surge resistor, which can absorb or disperse overcurrent / overvoltage to protect subsequent circuits. The rectifier and filter unit consists of a rectifier bridge and at least one filter capacitor, used to convert AC power into smooth DC power. After the mains power is filtered by the rectifier and filter unit and regulated by the voltage regulator unit, it outputs a working voltage adapted to the control module and the execution module. The voltage regulator unit includes a metering and monitoring module, a filter element, and a step-down chip, used to monitor electrical parameters and output a stable DC voltage.

[0031] In this embodiment, the voltage conversion module is constructed using a rectifier bridge (corresponding to MB10F type components in the circuit diagram), capacitors (corresponding to filter capacitors such as CD1 and CD2), and a voltage regulator chip (corresponding to voltage regulation units such as U6) to ensure voltage conversion and stable output.

[0032] As a further explanation:

[0033] The roller shutter door controller also includes a wireless communication module, which is connected to the control module and is used to receive external wireless control signals. The wireless communication module is a high-frequency module with an operating frequency of 433.925 MHz.

[0034] In one embodiment, the wireless communication module includes an antenna, a resonant element, and a signal processing chip connected in sequence. The antenna is used to transmit and receive wireless signals in the 433.925MHz band. After being matched and resonated by the resonant element, the signals are transmitted to the signal processing chip (corresponding to a PT690 type chip in the circuit diagram) for processing. The signal processing chip is connected to the control module and transmits the decoded wireless control signal to the control module to realize the interaction of wireless control commands.

[0035] Combined with appendix Figure 2 and 3 As shown, K1, K2, and K3 are relays used to control the on / off state of the circuit;

[0036] F1 is a surge resistor used for overcurrent protection;

[0037] HV1 is a terminal block used for connecting external wires to enable the controller to connect to external devices;

[0038] SW1 and SW2 are switches used for function triggering and mode switching;

[0039] DB1 is a rectifier bridge, and the model can be MB10F; D1 is a diode, and the model can be ES1J rectifier.

[0040] IC1 is a microcontroller, model number 60F011A; IC2 is a driver chip, model number 2001D; IC3 is model number PT790.

[0041] The resistors include R1 (1K), R2 (110K), R3 (4.7K), R4 (3K), and R5 (4.7K), which serve to limit current and divide voltage.

[0042] The capacitors include CD1, CD2, C2, C3, C4, C5, C6, C7, and C8. Among them, CD1 (4.7uF / 400V) and CD2 (470uF / 25V) are electrolytic capacitors used for filtering and energy storage; C2-C8 are surface mount capacitors used for auxiliary filtering and voltage stabilization.

[0043] L1 (1uH102) and L2 (39NH) are inductors, which serve as filters, energy storage, and anti-interference agents;

[0044] ANT stands for Antenna, used for wireless signal transmission and reception.

[0045] The above principle is as follows:

[0046] An external power supply is connected through the terminal block. After being protected by surge resistor F1, it is filtered and regulated by capacitors (CD1, CD2, etc.) to provide a stable operating voltage for chips (IC1, IC2, etc.), relays, etc.

[0047] The input commands from the switches (SW1, SW2) are transmitted to the chip via resistors and other components. After processing by the chip, control signals are output to the relays (K1, K2, K3). The relay contacts then control the on / off state of the loads, such as the roller shutter door motor.

[0048] The chip interacts with external (such as remote control) or other internal modules through inductors (L1, L2) and antennas (ANT); among them, diodes, capacitors and other components assist in voltage regulation and filtering in each link to ensure stable circuit operation.

[0049] Example 2

[0050] Referring to the components in Example 1, and referring to the appendix... Figure 4 The circuit schematic shown provides an embodiment.

[0051] The diagram above, shown on the right, illustrates the composition and principle of a voltage conversion circuit, as detailed below:

[0052] After the 220V AC mains power is connected, it first passes through surge resistor R1 (RX12W type, which uses its own characteristics to absorb and disperse overcurrent / overvoltage to protect the subsequent circuits);

[0053] Next, the current enters the rectifier bridge U1 (model MB10F), which converts the alternating current into pulsating direct current based on the unidirectional conductivity of the diode.

[0054] The converted electrical signal is initially filtered by capacitor CD1 (4.7UF / 400V) (allowing AC and blocking DC, smoothing the voltage);

[0055] Subsequently, one path is divided by resistors R73 (110K) and R3 (4.7K) to monitor electrical parameters (such as voltage and current) with the metering module U (METER); the other path is filtered by capacitor C4 (105P / 25V), processed by diode D4 (SS34, to maintain voltage stability or provide a freewheeling circuit), and then further regulated by inductor L2 (1MH (102), which passes DC and blocks AC to suppress high-frequency interference) and capacitor CD7 (470UF / 25V, for further filtering) to obtain an intermediate voltage of +11.8V.

[0056] Finally, the voltage is precisely stepped down by the step-down chip U6 (78M05) to output a stable +5V voltage, which is then filtered by capacitor C31 (104P, to eliminate high-frequency noise) to power the control circuit and high-frequency module.

[0057] The diagram below, shown on the left side of the circuit, illustrates the composition and operating principle of the control and execution modules, as detailed below:

[0058] 1. First, signal reception and processing:

[0059] The high-frequency antenna (ANT, ANTENNA) receives 433.925M wireless signals, which are then filtered by a frequency selection filter circuit composed of capacitors C1 (2.2P) and C2 (5.6P) and inductors L1 (27NH) and L2 (39NH) (using the resonant characteristics of capacitors and inductors to filter the target frequency band signal) before entering the high-frequency chip U1 (PT690).

[0060] The crystal Y1 (13.52127) provides a stable clock signal for the PT690. The chip demodulates and decodes the signal, extracts rising, falling, and stop instructions, and transmits them to the control chip U3 (30E, 2001, etc.) for processing.

[0061] The learning key signal is input through resistor R7 (10K, current limiting) and enters the control chip together with the wireless command to expand the command sources.

[0062] 2. Secondly, the execution control section:

[0063] The control chip U3 outputs a signal to drive the coil of relay K2 (RELAY-SPDT) to be energized / de-energized (the coil is connected to +11.8V and the chip output terminal); the relay contacts then close / open, controlling the 220V mains power to be supplied to the roller shutter door motor M7, realizing the motor's forward / reverse / stop rotation, and driving the roller shutter door to move.

[0064] This solution eliminates the need for traditional transformers. By using a step-down chip and filter circuit, it adapts to 100V-275V mains power, copes with grid fluctuations, reduces costs and size, and improves applicability.

[0065] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
